RESEALABLE CONTAINER LID AND ACCESSORIES INCLUDING METHODS
OF MANUFACTURE AND USE
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This Application under the Patent Cooperation Treaty (PCT) claims
the benefit of
United States Patent Application Serial Number 15/056,216, filed February 29,
2016.
TECHNICAL FIELD
[0002] The present invention relates to a resealable lid and cap
combination for a
container, including the structure, method of manufacturing, and method of use
thereof. In
general, the resealable lid is assembled to a container such as an aluminum
beverage can. The
cap is assembled to the lid and rotated by the consumer to open and reseal the
can. The
rotational movement of the cap is converted into linear motion by one or more
cam
mechanisms to effect an opening action, fracturing a score line and bending a
tear panel
inward into the can. Once the can is opened, the cap can be removed for
consumption of
content stored therein and replaced to reseal the opened lid.
BACKGROUND OF THE PRESENT INVENTION
[0003] The beverage and can industries have long sought to create a can
that is both
economical to produce and convenient for use by consumers. In the past,
beverage cans were
provided with a "pull tab" which the consumer would grab by a ring, and pull
until the tab
was removed from the can. This created a problem in that the tab became
disposable waste
for which the consumer was responsible to ensure proper disposal. Often the
consumer failed
to properly dispose of the tab, thereby creating not only litter, but also a
safety issue, in that
the tabs could be swallowed by small children. Moreover, the edges of the pull
tab were sharp
enough that they could, if mishandled, cut the fingers or hands of the
consumer or anyone
else who handled a loose pull tab. As a result of these problems, the industry
moved in the
1
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
direction of a tab that stayed on the can after opening, thereby preventing
both litter and any
sharp edges from coming into contact with consumers.
[0004] The present state of the art is to have a "stay on" tab that is
attached to the can lid
by a rivet formed in the can lid next to the opening. The opening is formed by
a score line, or
frangible "kiss cut" which breaks when the tab is pulled up by the consumer.
The score line,
when broken, produces a hinged flap that stays connected to the can lid, but
inside the can.
[0005] Beverage cans with stay on tabs suffer from at least the following
deficiencies.
First, they are not resealable, so that once the consumer opens the beverage;
the contents are
subject to loss of carbonation, and the influx of foreign material due to the
contents being
open to the surrounding environment. Secondly, in order to form the rivet
which is used to
secure the stay on tab to the beverage lid, the lid needs to be made of a
different material,
typically an aluminum alloy that is stronger than the aluminum alloy used to
make the sides
and bottom of the can. Further, the tab itself is typically made of a
different alloy than the
sides and lid, reflecting the need for a still stronger, typically stiffer
material. As a result,
recycling of the aluminum beverage can is problematic because the different
materials need
to be separated. The use of three different materials also tends to add
complexity, and
expense, to the finished container.
[0006] A need exists for improved beverage containers that are resealable,
cost effective
to produce, and "green" in terms of avoiding waste and facilitating the
recycling of aluminum
cans. Concurrently, a need exists for improved methods for manufacturing
beverage
containers that result in faster production time, lower production costs, and
improved
products.
BRIEF DESCRIPTION OF THE PRESENT INVENTION
[0007] A container has a sidewall and integrally formed bottom. The
container is
preferably a beverage container, but could be adapted to any suitable
container. A top lid
includes a socket integrally formed therein; the socket including a
substantially cylindrical
sidewall and a bottom wall. A score line formed in the bottom wall defines a
tear panel which
forms an opening into the can when the score line is fractured and the tear
panel is bent
inward or removed. A cap is fitted in the socket and has a sidewall which is
formed with cam
2
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
surfaces. The cam surfaces, formed as grooves or slots, cooperate with bosses
or detents
formed in the cylindrical sidewall of the socket. The design of the cam
surfaces and
associated bosses translate the rotational motion of the cap into linear
motion, wherein the
linear motion fractures the score line and opens the tear panel. As the cap
moves
downwardly, a protrusion formed on the lower surface of the cap impinges on
the periphery
of the score line, fracturing the score line and subsequently pushing the tear
panel into the
can.
[0008] Once opened, the cap can be re-fitted into the socket, so that the
cam surfaces
engage the detents, and are rotated to achieve a sealing position, whereby the
contents of the
can are protected from the ambient atmosphere. This will result in the
prevention of spillage,
the loss of carbonation, and the prevention of foreign objects from entering
the can. The user
can opt to discard the cap and/or container once the entire contents of the
can are consumed.
[0009] Preferably, the container is a beverage container, commonly referred
to as a "can."
but the same principals described above could be used for other types of
containers, including
bottles made of various materials, including plastic. paper, metal (such as
aluminum),
cartons, cups, glasses, etc. In one particularly preferred embodiment, the
container can be an
aluminum can with a body manufactured of an aluminum alloy material, and a
container lid
being manufactured of the same aluminum alloy material as the container. The
cap can be
made of a plastic material of sufficient hardness that the cam surfaces do not
deform during
opening and closing operations, a metal, or any other suitable material.

[00442] A container 100, exemplified as a beverage container in FIGS. 1
through 12,
includes a container cylindrical sidewall 202, a container closed container
closed bottom wall
204, integrally formed with the container cylindrical sidewall 102 and a
resealable container
lid 110 connected to the container cylindrical sidewall 102 at the end
opposite the container
closed container closed bottom wall 204. In the illustrated embodiment, the
container 100 is a
beverage container commonly referred to as a can, wherein the container closed
container
closed bottom wall 204 and the container cylindrical sidewall 102 are formed
from a single
piece of aluminum material, using otherwise known processes. The aluminum
material is a
lightweight aluminum alloy commonly used in the beverage can industry. The
resealable
container lid 110 is preferably made of the same lightweight aluminum alloy
material, and is
joined at the upper end of the sidewall through likewise known processes. The
resealable
container lid 110 includes a cap receiving socket 130 which extends downwardly
into the
container 100 from a resealable container lid upper surface 114. The cap
receiving socket 130
is formed near a peripheral edge or lip of the resealable container lid 110 as
is customary in
the art, to allow drinking from the container 100. A resealable container cap
160 fits into the
cap receiving socket 130 and engages same in a manner described in more detail
below. The
container cylindrical sidewall 202 of the container 100 is preferably tapered
at both the upper
and lower ends to provide greater structural integrity, particularly for use
with pressurized
contents, such as when used for carbonated beverages.
[00443] The resealable container lid 110 has an outer perimeter that is
connected to the
upper open end of the container cylindrical sidewall 102 of the beverage
container, using
known processes, to form an enclosure which contains a beverage. Beverages
contained
therein are not limited, but include carbonated or non-carbonated beverages,
and could also
include foodstuffs, and non-edible products. The cap receiving socket 130 is
integrally
formed in the resealable container lid upper surface 114 of the resealable
container lid 110
and includes a cap receiving socket cylindrical sidewall 132, which extends
downwardly into
the container 100, and a cap receiving socket bottom wall 134. A cap receiving
socket bottom
panel circular score line 136 is formed in the cap receiving socket bottom
wall 134 in order to
create a cap receiving socket bottom panel tear panel 138 (see FIGS. 13B, 13C
and 13D)
which is pushed into the can when the can is opened. In the opened position,
the cap
receiving socket bottom panel tear panel 138 remains connected to the cap
receiving socket
bottom wall 134 due to the fact that the cap receiving socket bottom panel
circular score line
54
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
136 does not make a complete circle or loop; a tear panel hinge 139 is created
where the cap
receiving socket bottom wall 134 is not scored (see FIG. 5).
[00444] As seen in figures, the resealable container cap 160 is sized to
fit substantially
within the cap receiving socket 130, and includes a flat annular cap bottom
sealing surface
167 which is disposed between the cam shaped cap bottom surface 166 and the
cap's
resealable container cap cylindrical sidewall 162. In FIG. 9, the cap
receiving socket bottom
wall 134 of the cap receiving socket 130 may include a cap receiving socket
bottom panel flat
annular surface 140 which is disposed between the cap receiving socket
cylindrical sidewall
132 and the cap receiving socket bottom panel circular score line 136. When
assembled and
in the "resealed" position shown in FIG. 13D, the flat annular cap bottom
sealing surface 167
of the resealable container cap 160 comes into contact with the cap receiving
socket bottom
panel flat annular surface 140 of the bottom of the cap receiving socket 130
to effectively
reseal the container 100.
[00445] The resealable container lid 110 has a shallow, resealable container
lid upper
surface reinforcement formation 118 which serves two purposes. First, the
resealable
container lid upper surface reinforcement formation 118 acts as a stiffening
structure to
provide greater strength to the resealable container lid 110. This is
particularly advantageous
if the resealable container lid 110 is to be made of the same aluminum alloy
as the container
cylindrical sidewall 102 and container closed container closed bottom wall 204
of the
container 100. Secondarily, the resealable container lid upper surface
reinforcement
formation 118 adds a familiar look to consumers who are accustomed to the
prior art
beverage containers employing a pull tab that is operated first in an opening
direction, and
then secondly, in a seated direction, where the hinged pull tab is positioned
after opening.
[00446] As shown in FIGS. 2, 3 and 5. the cap receiving socket cylindrical
sidewall 132 of
the cap receiving socket 130 has a plurality of equally spaced socket sidewall
cam engaging
projections 150, disposed substantially on the same plane and being integrally
formed in the
sidewall 22. FIG. 5 shows one protrusion as an indentation or recess, since
FIG. 5 shows the
outer cylindrical sidewall 132 of the resealable container lid 110, whereas
the other figures
show the inner cap receiving socket cylindrical sidewall 132 of the resealable
container lid
110. The socket sidewall cam engaging projections 150 cooperate with the
resealable
container cap 160 in a manner described below in order to open and reseal the
container 100.
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00447] Referring to FIGS. 5-7, the resealable container cap 160 has a
radially extending
cap skirt 170 which acts as a tamper proof indicator. As seen in FIG. 1, prior
to opening the
container 100, the radially extending cap skirt 170 seats flush with the
resealable container lid
planar upper surface outer segment 119 of the resealable container lid 110.
The skirt is
integrally formed with the resealable container cap 160, which is preferably
made of plastic
material. The radially extending cap skirt 170 includes a series of radially
extending cap skirt
frangible score lines 172, extending radially outwardly, which are operable to
break during
the opening operation of the can. The breaking of the score lines 172 is
effected by the skirt
170 being driven downwardly as the resealable container cap 160 is twisted or
rotated and
thereby advances downwardly into the cap receiving socket 130. Opening of the
beverage
container will thus be evident by the broken score lines 172 of the radially
extending cap skirt
170, and preferably, by the sections of the radially extending cap skirt 170
that are formed by
the broken score lines 172 extending at an angle upwardly, thus extending
radially outwardly
and radially upwardly.
[00448] The resealable container cap 160 is preferably made of a molded
plastic material,
is sized to fit substantially within the cap receiving socket 130, and
includes a cam shaped
cap bottom surface 166 formed at the lower or inner end of a resealable
container cap
cylindrical sidewall 162. The cam shaped cap bottom surface 166 may include an
integrally
formed sharp or pointed offset projecting incisor 168 disposed offset to the
center axis of the
resealable container cap 160 and extending downwardly into the cap receiving
socket 130
when the resealable container cap 160 is assembled in the cap receiving socket
130. When
assembled, the offset projecting incisor 168 is disposed immediately above the
cap receiving
socket bottom panel circular score line 136, so that when the resealable
container cap 160
moves downwardly during opening of the container 100 offset projecting incisor
168
punctures the can at the beginning of the cap receiving socket bottom panel
circular score line
136, next to the tear panel hinge 139, then progressively propagates the
rupture along the cap
receiving socket bottom panel circular score line 136 to its terminus on the
opposite end of
the tear panel hinge 139.
[00449] The cam shaped cap bottom surface 166 may also include a centered
projecting
incisor 169 disposed on the center axis of the resealable container cap 160
and extending
downwardly into the cap receiving socket 130 when the resealable container cap
160 is
assembled in the cap receiving socket 130. When assembled, the projection 169
is disposed
56
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
immediate above a cap receiving socket bottom panel centered "X" shaped score
line 142, so
that when the resealable container cap 160 moves downwardly during opening of
the
container, the projection punctures the can at the cap receiving socket bottom
panel centered
"X" shaped score line 142, thereby relieving internal pressure and assisting
in the rupturing of
the cap receiving socket bottom panel circular score line 136 by the offset
projecting incisor
168.
[00450] The opening operation of the container 100 is made possible by forming
a cam
structure between the cap receiving socket 130 and the resealable container
cap 160. In
particular, cam groove surfaces 180 are formed in the resealable container cap
cylindrical
sidewall 162 of the resealable container cap 160. The socket sidewall cam
engaging
projections 150 are fitted into and engage the cam groove surfaces 180 such
that when the
resealable container cap 160 is hand-twisted by the consumer, rotational
motion of the
resealable container cap 160 is converted into linear motion of the resealable
container cap
160 thus driving the cap in a downward direction relative to the cap receiving
socket 130. As
the resealable container cap 160 moves downwardly, the cap receiving socket
bottom panel
circular score line 136 is ruptured by the offset projecting incisor 168, then
progressively
propagates the rupture along the cap receiving socket bottom panel circular
score line 136 to
its terminus. In an alternate embodiment, an optional cap receiving socket
bottom panel
centered "X" shaped score line 142 may be ruptured by the centered projecting
incisor 169
immediately before the cap receiving socket bottom panel circular score line
136 is ruptured
by the offset projecting incisor 168, to thereby relieve internal pressure and
assist in the
rupture of the cap receiving socket bottom panel circular score line 136 by
the offset
projecting incisor 168.
[00451] As shown in FIG. 8, the resealable container cap 160 includes a
resealable
container cap grip element 174 for the consumer to grab when ready to open the
beverage
container, and also, as described below, for resealing the beverage container
after opening.
Depending on the contour of the cam surfaces and their direction of
orientation, the cap can
be rotated in one direction, preferably clockwise for opening, and then in the
opposite
direction, counterclockwise, to remove the cap during consumption of beverage,
and then
again back to the can-opening direction for resealing the beverage container
if the contents
are not entirely consumed. Symmetry of disposition of the three socket
sidewall cam
engaging projections 150 is shown in FIG. 9, wherein the three socket sidewall
cam engaging
57
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
projections 150 are located at approximately equal angular intervals of 120
degrees. Each
projection engages a corresponding cam groove surface 180, more specifically,
a first cam
groove surface 181, a second cam groove surface 182, and a third cam groove
surface 183.
As shown in the illustrated embodiment, the resealable container cap
cylindrical sidewall 162
of the resealable container cap 160 would be contoured, as by forming grooves,
to form three
cam groove surfaces 181, 182, 183. The cam surfaces or features 181. 182, 183
are shaped
and sloped in a manner designed to cause the resealable container cap 160 to
advance into an
opening position without more than a quarter to half a turn, and as measured
in radians, this
would be no more than 1 to 2 radians. The number of projections and cam
elements can be
varied, although three provides a balance between cost and effectiveness.
[00452] The cap resealable container cap cylindrical sidewall 162 includes
three equally
spaced cam groove surfaces 181, 182 and 183, as best shown in FIGS. 10 and 11.
The cam
groove surfaces 181 and 182 and the resealable container cap grip element 174
extending
across the page are best illustrated in FIG. 10. The resealable container cap
bottom surface
164 of the resealable container cap 160 includes the centered projecting
incisor 169, acting as
a piercing element, which punctures the cap receiving socket bottom panel
centered "X"
shaped score line 142, and it further includes an offset projecting incisor
168 which also acts
as a piercing element. The projection 168 is designed and shaped to impinge on
the cap
receiving socket bottom wall 134 of the cap receiving socket 130 inside and
juxtaposed the
cap receiving socket bottom panel circular score line 136. As the resealable
container cap 160
is rotated, from the unopened position shown in FIG. 10, the cam structure
turns the
rotational movement to translational movement, thus moving the cap inwardly.
As the
resealable container cap 160 moves inwardly, the offset projecting incisor 168
rotates until,
preferably, it reaches the position shown in FIG. 11, wherein a portion of the
cap receiving
socket bottom wall 134 breaks away and is pushed inwardly to form the cap
receiving socket
bottom panel tear panel 138 that remains hinged to the cap receiving socket
bottom wall 134
by virtue of the cap receiving socket bottom panel circular score line 136 not
extending to a
complete loop. The offset projecting incisor 168 starts at the beginning of
the cap receiving
socket bottom panel circular score line 136 and only travels ninety degrees
(90 ). Thus, offset
projecting incisor 168 will only have traveled a portion of the length. What
pushes the cap
receiving socket bottom panel tear panel 138 out of the way is the body of the
cam shaped
cap bottom surface 166 going past the plane of the cap receiving socket 130
cap receiving
58
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
socket bottom wall 134. Notice that the cam shaped cap bottom surface 166
protrudes out
from the flat annular cap bottom sealing surface 167.
[00453] Cross sectional views of the cap moving between opening and resealing
positions
are shown in FIGS. 13A through 13D. In FIG. 13A, the resealable container cap
160 is shown
in cross section prior to opening the beverage container. Thus, the cap
receiving socket
bottom wall 134 of the cap receiving socket 130, the cap receiving socket
cylindrical sidewall
132 of the cap receiving socket 130, and the resealable container lid upper
surface 114 form
the resealable container lid 110. The resealable container cap 160 is shown in
the storage
position, i.e., pre-opening of the can, in FIG. 13A, wherein the cap receiving
socket bottom
wall 134 is not punctured and the contents of the container 100 are air tight
for potentially
long term storage. The resealable container cap grip element 174 is shown in a
first,
unopened position. In this position the flat annular cap bottom sealing
surface 167 of the
resealable container cap 160 is spaced above the socket cap receiving socket
bottom wall
134, but the offset projecting incisor 168 is close to or in slight contact
with the cap receiving
socket bottom panel circular score line 136. Similarly, if a second centered
projecting incisor
169 is employed at the center of the lower end of the resealable container cap
160, it is also
disposed in close proximity to the score line 44 if not slightly touching.
[00454] The resealable container cap 160 is rotated clockwise approximately
ninety
degrees (90'1, as shown in FIG. 13B. Engagement between the cam groove
surfaces 180 and
the socket sidewall cam engaging projections 150 translates the resealable
container cap 160
downwardly by a distance sufficient to cause the offset projecting incisor 168
to rupture the
cap receiving socket bottom panel circular score line 136 as the projection
moves along the
inner side of the score line. The rupture creates a cap receiving socket
bottom panel tear panel
138 which is pushed by the offset projecting incisor 168 into the interior of
the container 100
by rotating downwardly about a tear panel hinge 139, wherein the tear panel
hinge 139 is
formed spanning between opposite ends of the cap receiving socket bottom panel
circular
score line 136. The opposite ends of the score line 136 are positioned to
locate and define a
pivot axis of the tear panel hinge 139 for the cap receiving socket bottom
panel tear panel
138.
[00455] After the cap receiving socket bottom panel tear panel 138 is formed,
and the
resealable container cap 160 is disposed at its innermost position relative to
the socket, the
consumer would then rotate the resealable container cap 160 counterclockwise,
preferably by
59
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
turning the resealable container cap grip element 174. The resealable
container cap 160 is
shown in FIG. 13C being separated from the container 100, and can be pocketed
by the
consumer, or placed in a location for easy access in case the consumer chooses
not to
consume the entire contents of the container 100. As evidence that the
beverage container has
been opened, the radially extending cap skirt 170 may be angled upwardly as a
result of the
frangible score lines being broken, so that individual sections of the skirt
are now biased in an
upward direction. Also, when rotating counterclockwise, the cam groove
surfaces 180 and the
socket sidewall cam engaging projections 150 will eventually separate,
allowing the
resealable container cap 160 to be free of the container 100.
[00456] In the event that the consumer wishes to reseal the container 100, and
as shown in
FIG. 13D, the resealable container cap 160 is brought into contact with the
cap receiving
socket 130 by the consumer, by bringing the cam groove surfaces 180 into
engagement with
the socket sidewall cam engaging projections 150. Once this occurs. clockwise
rotation will
cause the resealable container cap 160 to translate downwardly until a
sealing, seating
arrangement is made between the cap receiving socket bottom panel flat annular
surface 140
of the socket cap receiving socket bottom wall 134 and the flat annular cap
bottom sealing
surface 167 of the resealable container cap 160, thereby keeping the contents
of the container
100 fresh and safe from foreign contaminants. The seal will retain carbonation
when the
contents are carbonated.
[00457] The resealable container cap 160 can be removed again and again to
gain access to
the contents of the beverage container until all contents are consumed. There
is no limit to the
type of beverages or other contents that can be housed in the container 100,
but most
commonly "canned" beverages include sodas, beer, juices, etc. It is also
within the scope of
the present invention that the contents of the containers could be foodstuff,
and non-
consumable liquids, gels, powders, and the like.
[00458] The cam means disclosed herein can be used for caps that provide other
functionality for the container 100. For example, a variation of the
resealable container cap
160 would be one that could include a passageway extending through the
resealable container
cap 160 with drinking implements formed at the upper, outer end, such as a
child's sip cup,
which would allow a child to drink from the container 100 without spilling.
Alternatively, the
resealable container cap 160 could be formed with an infant nipple for feeding
formula, juice,
water or other beverages suitable for infants. When using drinking implements
such as sip
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
cup and baby bottle nipples, a resealable container cap 160 would nonetheless
have to be
employed for opening the container, and then a second "cap" could be used for
consuming
the contents. In any event, the opening caps and drinking implements could be
sold separately
from the container 100, as long as the container 100 included the socket
sidewall cam
engaging projections 150 formed in the cap receiving socket cylindrical
sidewall 132 of the
cap receiving socket 130.
[00459] Although a wide range of plastic materials could be used to form the
resealable
container cap 160, other materials could be used, including ceramics and
metals. However,
for harder materials such as these, it may be necessary to position a gasket
between the
opposing annular surfaces 140, 167 of the socket 130 and the cap 160,
respectively to ensure
the best possible seal.
[00460] While the embodiments described herein place the socket 130 and cap
160 in the
top of the container 100, it is possible to have the same opening and
resealing structures in
the container closed bottom wall 104 of the container 100. Also, while a
cylindrical container
100 has been described herein, other shapes of containers, e.g., oval,
rectangular, hexagonal,
octagonal, and the like, could also be used.
[00461] The preferred shape of the frangible cap receiving socket bottom panel
circular
score line 136 in the bottom of the cap receiving socket 130 is circular, with
a closed end and
an open end. The inside score (shallower line) terminates in a curve arcing
towards the
socket's cylindrical sidewall to prevent loss of tear panel into the
container. The outside score
line (deeper line) terminates in circular form spaced from the inside score
line. There is a
hinged portion of the tear panel that keeps the panel in contact with the lid
once ruptured, as
described above.
[00462] The offset projecting incisor 168, described as a piercing element, is
intended to
be a single point of contact that moves deeper, and radially along the inside
of the cap
receiving socket bottom panel circular score line 136 while the resealable
container cap 160
is rotated. The offset projecting incisor 168 may also include additional
areas to further drive
the cap receiving socket bottom panel tear panel 138 deeper into the
container. A single point
will apply more force to breaking the cap receiving socket bottom panel
circular score line
136 defining the cap receiving socket bottom panel tear panel 138 but
additional areas acting
in a secondary fashion could help in the opening process.
61
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00463] The socket sidewall cam engaging projections 150 used in the cap
receiving
socket 130 allow the use of a very shallow socket 130 (as compared to threaded
designs) and
still provide positive opening, closing and sealing of the resealable
container cap 160. The
design of the socket sidewall cam engaging projections 150 also provides for
positive stops
for open, closed and removable cap positions. As seen in FIGS. 10 and 11, each
cam groove
surface 181, 182, 183 includes a sloped cam groove surface segment 184, a cam
groove
surface lower detent 186 and a cam groove surface upper detent 188. Once
assembled, the
three socket sidewall cam engaging projections 150 are respectively positioned
so that the
detents prevent the resealable container cap 160 from becoming disconnected
from the cap
receiving socket 130, during transport or storage, and from backing off a
sealing position,
when the resealable container cap 160 is positioned in a resealing position.
This can be
illustrated with reference to FIG. 11, where the socket sidewall cam engaging
projection 150
is shown as a broken line circle. When the resealable container cap 160 is in
the unopened
position, each socket sidewall cam engaging projection 150 (shown as a broken
line circle)
will be positioned next to the cam groove surface lower detent 186. The cam
groove surface
lower detent 186 prevents the resealable container cap 160 from turning to a
position where
the socket sidewall cam engaging projection 150 is disengaged from the first
cam groove
surface 181, as for example, if vibration or the like caused the projection
150 to pass out of
the sloped cam groove surface segment 184. Similarly, when the resealable
container cap 160
is intentionally rotated clockwise, to either open or reseal the beverage
container, the
projection passes over the cam groove surface upper detent 188 to become
locked by
interference fit between the cam groove surface upper detent 188 and the
socket sidewall cam
engaging projection 150. The cam groove surface upper detent 188 thus prevents
the
resealable container cap 160 from inadvertently backing out from the sealing
position. Thus,
the resealable container cap 160 is held in two positions by the detents 186,
188. The first
position can be referred to as a transport retaining position and the second
position can be
referred to as a closed position. The distance between the two detents,
measured along the
rotational axis of the resealable container cap 160 is equal to the distance
between the
resealing surface on the resealable container cap 160 and the associated
surface of the cap
receiving socket bottom wall 134. The transport retaining detent, or cam
groove surface
lower detent 186 restricts the rotary movement of the resealable container cap
160 due to the
interference between the stabilizing radially extending cap skirt 170 and the
flat upper rim of
the resealable container cap 160, as well as the interference between the
piercing element or
offset projecting incisor 168 and the socket cap receiving socket bottom panel
tear panel 138.
62
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00464] When turning the resealable container cap 160 in the opening
direction, e.g.,
clockwise, the socket sidewall cam engaging projections 150 on the socket's
cylindrical
sidewall follow the sloped cam groove surface segments 184 of the cam groove
surfaces 180,
which form gradual ramps, converting the rotary motion of the resealable
container cap 160
to a linear or translational movement, which drives the resealable container
cap 160 into the
interior of the container 100. This engages the offset projecting incisor 168
against the cap
receiving socket bottom panel tear panel 138 and provides the force necessary
to rupture the
cap receiving socket bottom panel circular score line 136. Further turning of
the resealable
container cap 160 in the opening direction progressively pushes the cap
receiving socket
bottom panel tear panel 138 out of the way and into the interior of the
container 100, until the
socket sidewall cam engaging projections 150 reach the closed position of the
cam groove
surface upper detents 188. A slightly higher point on the sloped cam groove
surface segment
184 of the cam groove surfaces 180 just before the closed position provides
the resistance
necessary to keep the resealable container cap 160 from backing out.
[00465] When turning the resealable container cap 160 opposite the opening
direction, the
socket sidewall cam engaging projections 150 follow the same route to their
starting positions
but after opening, the socket sidewall cam engaging projections 150 can pass
over the
transport retaining or cam groove surface lower detents 186 because the
stabilizing radially
extending cap skirt 170 and the cap receiving socket bottom panel tear panel
138 are now not
providing any interference between the transport retaining or cam groove
surface lower
detents 186 and the void between the cam groove surfaces 180, allowing the
resealable
container cap 160 to be freed from the container.
[00466] In the embodiments described and illustrated herein, the exemplary cam
groove
surfaces 180 are shown as grooves having a sloped segment that terminates at
opposite lower
and upper ends in a lower and an upper detent 186, 188 (respectively), whereby
the entire
cam groove surfaces or elements 181, 182, 183 were formed in the resealable
container cap
cylindrical sidewall 162 of the resealable container cap 160. It is equally
possible to form the
cam groove surfaces or elements 181, 182, 183 as projections or bosses from
the surface,
integrally formed therewith, or as separate parts connected to the resealable
container cap
160. Further, while the socket sidewall cam engaging projections 150, acting
as cam
followers, project from the cap receiving socket cylindrical sidewall 132 of
the cap receiving
socket 130, the cap receiving socket 130 could have been formed with cam
surfaces 181, 182,
63
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
183 and the cam followers or cam engaging projections 150 could have been
formed on the
resealable container cap 160. The exact size and shapes of the cam surfaces
181, 182, 183 can
be selected to correspond to the particular needs of the container 100. The
overall goal is to
select a structure that results in an operable torque which can be applied by
consumers
without exerting excessive effort.
[00467] The structures described above can be made using unique manufacturing
processes, which combine some of the known processing steps with new, modified
or
avoided steps. In one particularly preferred method of making containers 100,
as illustrated in
the flow chart of FIG. 14, preformed resealable container lids 110 are
provided from a shell
press. Next, cap receiving sockets 130 are formed in the resealable container
lids 110 using a
conversion press. Next, a score line is formed in the bottom of the cap
receiving socket 130 in
the conversion press, either at the same time, or sequentially after the cap
receiving socket
130 is formed. Resealable container cap 160 are formed by injection molding,
or other
suitable means, and the resealable container caps 160 are supplied to the
assembly line, where
they are inserted into the sockets. The resealable container caps 160 are then
secured to the
sockets by press forming the projections by spacing three dies around the
socket, all centered
on a common plane. The dies arc pressed inwardly against the cylindrical
sidewall of the cap
receiving socket 130, and the resealable container cap 160 acts as a mandrel
against the inner
pressing force of the dies, thus forming the socket sidewall cam engaging
projections 150 to
project into the grooves of the cam groove surfaces 180. The resealable
container lids 110 or
ends are then packaged and sent to bottlers, who can then use conventional
processing steps
to secure the lid to any of a variety of cans or other beverage containers.
[00468] The process described above achieves several cost and environmental
advantages
over the prior manufacturing techniques. First of all, the lid does not have
to be processed to
form a rivet, which has conventionally been used to secure a pull tab to a can
lid. There is no
need for a rivet because there is no need for the pull tab. The rivet required
the lid to be made
of stronger, thicker material, usually consisting of a different alloy of
aluminum as opposed
to the material that made up the sidewall and bottom. Moreover, the
conventional process
would have required the formation of a pull tab, likely to be made of third,
different
aluminum alloy. Use of three different aluminum materials presented a problem
for recycling,
whereas in the present invention, a single material can be used to form the
can body and the
can lid.

CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00469] Referring to FIG. 15, a further variation of manufacturing process is
disclosed. In
the first step a pre-formed resealable container lid 110 is provided from a
shell press with a
cap receiving socket 130 already formed. In the next step, the resealable
container lid 110 and
cap receiving socket 130 are aligned directionally for a conversion press.
Next a cap
receiving socket bottom panel circular score line 136 is created in the
conversion press, at the
bottom of the cap receiving socket 130. Molded resealable container caps 160
are provided to
the assembly line, and inserted into the molded resealable container cap 160.
The molded
resealable container caps 160 are secured to the cap receiving socket 130 by
forming the
socket sidewall cam engaging projections 150 in a manner described above, in
which the
resealable container cap 160 functions as a mandrel during formation of the
projections.
Next, the resealable container lids 110 with secured resealable container caps
160 are
packaged and shipped to bottlers or others for conventional filling, sealing,
and shipment to
customers. As in the previously described manufacturing process, there is no
need to form a
rivet in the resealable container lid 110, and no need to attach a pull tab to
the rivet. Avoiding
these steps saves money and makes the resulting product easier to recycle.
[00470] An alternative embodiment of a container 200 is shown in FIGS. 18
through 35,
and includes a body having a container cylindrical sidewall 202 and opposite
axial ends. The
container 100 and container 200 include a number of similar features. Like
features of the
container 100 and the container 200 are numbered the same except preceded by
the numeral
'2'. The container 200, like that of the previous embodiment (container 100),
is illustrated in
the size and shape of a common aluminum can used today for a wide variety of
beverages,
including soft drinks, juice drinks, beer, and the like. The body itself
differs from the prior art
in the features at the top end or lid of the container 100 where the features
of the present
invention allow for opening and resealing the container 200.
[00471] A container closed bottom wall 204 (seen in FIG. 20) is integrally
formed at one
of the axial ends with the container sidewall 202 in the known fashion of
making aluminum
cans. However, the body (202, 204) can be made of other materials and have
other shapes,
depending on either style, functionality or a combination of both. A
resealable container lid
210 is attached to the open axial end of the body, at the open end defined by
the container
cylindrical sidewall 202, after filling the body (202, 204) with a beverage in
the ordinary, and
known, way of attaching resealable container lids or tops 110 to the
containers 200. After
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
assembly, the resealable container lid 210, container closed bottom wall 204
and container
cylindrical sidewall 202 define a closed, interior space.
[00472] A cap receiving socket 230 is formed in the resealable container lid
210 and
includes a cylindrical sidewall 110 and a cap receiving socket bottom wall
234. The cap
receiving socket 230 is located eccentrically so that it nears a peripheral
edge of the
resealable container lid 210 to facilitate drinking and pouring after opening.
The cap
receiving socket 230 further includes a cap receiving socket bottom panel
circular score line
236 slightly inset from the peripheral edge of the cap receiving socket bottom
wall 234 and
forming a cap receiving socket bottom panel substantially closed loop tear
panel 238. An cap
receiving socket bottom panel centered score line 242 is provided at the
center of the bottom
wall cap receiving socket bottom wall 234 and preferably includes two
intersecting score
lines that form an -X" with the intersection of the two lines being at the
center of the cap
receiving socket bottom wall 234. The cap receiving socket bottom wall 234
further includes
socket bottom panel ramps 290, 291, 292 which are equidistantly spaced around
the
periphery of the cap receiving socket bottom wall 234 inside the cap receiving
socket bottom
panel circular score line 236. A different number of ramps could be used, but
three is
preferable. The socket bottom panel ramps 290, 291, 292 are integrally formed
in the cap
receiving socket bottom wall 234.
[00473] The cap receiving socket 230 further includes equidistantly spaced
socket sidewall
cam engaging projections 252, 254, 256 formed in the sidewall 110. From an
interior view,
such as that shown in FIGS. 22 and 34, the projections such as projections 124
and 128 are
shown as indentations, since the projections are formed from the sidewall
material. The
resealable container lid 210 also includes a resealable container lid upper
surface
reinforcement formation 218, as in the previous embodiment, which may include
instructional text to inform the consumer how to use the opening and resealing
features of the
container 200.
[00474] A resealable container cap 260 fits into the cap receiving socket 230
and includes
a resealable container cap cylindrical sidewall 262 and a bottom wall 136. A
series of cam
groove surfaces 281, 282, 283 are provided in the resealable container cap
cylindrical
sidewall 262 of the resealable container cap 260 at equidistantly spaced
locations and are
designed to receive the cam engaging projections 252, 254, 256, respectively,
of the cap
receiving socket 230, when the resealable container cap 260 is assembled
within the cap
66
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
receiving socket 230. In this regard, the embodiment of container 200 is
similar to that of the
embodiment of container 100. When assembled and before opening the container,
the
resealable container cap 260 seats in the cap receiving socket 230 as shown in
FIGS. 30
through 32.
[00475] The resealable container cap 260 further includes a resealable
container cap
handle or grip element 274 at the upper end of the resealable container cap
260 so that the
consumer can turn the cap in either clockwise or counterclockwise directions.
As in the
previous embodiments, the upper perimeter of the resealable container cap 260
is provided
with a radially extending cap skirt 270 which provides a tamper resistant
feature, whereby the
skirt would extend upwardly if the cap had been turned to cause the resealable
container cap
260 to descend further into the cap receiving socket 230. The radially
extending cap skirt 270
and all other features of the resealable container cap 260 are integrally
formed in a one-piece
construction preferably of a plastic material. Within the scope of the
invention, other
materials could be used including ceramic and metallic materials.
[00476] A sharp centered incising projection 269 is formed in the center of
the bottom
surface of the resealable container cap 260, so that when the resealable
container cap 260 is
fitted in the cap receiving socket 230, prior to opening the beverage can 100,
the point of the
sharp centered incising projection 269 is positioned next to or juxtaposed at
the center of the
bottom surface of the cap receiving socket 230, at the point of intersection
between the two
lines that form the cap receiving socket bottom panel centered score line 242.
The sharp
centered incising projection 269 punctures the cap receiving socket bottom
wall 234 of the
cap receiving socket 230 as the resealable container cap 260 moves linearly
downwardly and
further into the cap receiving socket 230 during opening operation of the
beverage can 200.
[00477] An offset projecting incisor 268 is formed along an outer region of
the bottom
surface of the resealable container cap 260, so that when the resealable
container cap 260 is
fitted in the cap receiving socket 230, prior to opening the beverage can 100,
the point of the
sharp offset projecting incisor 268 is positioned in alignment with the cap
receiving socket
bottom panel circular score line 236 formed in the bottom surface of the cap
receiving socket
230, as best shown in FIG. 30. The sharp offset projecting incisor 268
fractures the cap
receiving socket bottom panel circular score line 236 formed in the cap
receiving socket
bottom wall 234 of the cap receiving socket 230 as the resealable container
cap 260 moves
67
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
linearly downwardly and further into the cap receiving socket 230 during
opening operation
of the beverage can 100.
[00478] To understand how the embodiment of container 200 operates, reference
is made
to FIG. 25, which is a top view of the beverage container prior to opening.
Optionally, the
resealable container lid upper surface reinforcement formation 218 is
embossed, printed or
otherwise marked with instructions for how to use the resealable container cap
260. First, the
consumer is instructed to open the beverage container by turning, or rotating,
the resealable
container cap 260 in the clockwise direction. The degree of slope on the ramps
and the degree
of slope on the spiral grooves is selected to ensure that the container 200
can be opened with
the same or similar amount of force used to open a conventional beverage
container, such as
a soda can. This can be accomplished with a turning motion of the cap that is
in the range of
45 to ninety degrees (45-90 ), preferably.
[00479] After the resealable container cap 260 is rotated or turned to the
full extent
allowed, the resealable container cap 260 pushes the cap receiving socket
bottom panel loop
tear panel 238 into the can, but the tear panel 238 stays connected to the
resealable container
lid 210 through a portion of the lid between the ends of the cap receiving
socket bottom panel
circular score line 236. In order to then drink the contents of the container
200, the consumer
turns, twists or rotates the resealable container cap 260 in the opposite
direction until
returning past the starting point from where the opening rotation started,
placing the cam
engaging projections 252, 254, 256 in the opened area of the cam groove
surfaces 281, 282,
283.
[00480] At that point, the resealable container cap 260 is pulled upwardly by
the consumer
to become separated from the container 200, and the consumer is then free to
drink from the
opening formed in the resealable container lid 210 as a result of the cap
receiving socket
bottom panel substantially closed loop tear panel 238 being pushed into the
container 100.
When the consumer is finished drinking, and if the container 200 is not empty,
the consumer
can reseal or close the beverage container by pushing the resealable container
cap 260 back
into the cap receiving socket 230 and then turning, twisting or rotating the
resealable
container cap 260 in the same direction as the opening direction, until the
resealable container
cap 260 is fully seated in the cap receiving socket 230, thus sealing the
opening in the
container 200. In the resealed state, the contents of the container 200 can be
kept fresh,
68
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
carbonated (in the case of carbonated drinks), and spill-proof (when the
beverage container
200 is mobile, such as if kept in a back pack, stroller, automobile drink
holder, and the like).
[00481] As in the other embodiments described herein, the invention includes
an
assembled container 200, with or without contents, with a unique resealing
mechanism. The
invention also includes a container subassembly comprising a resealable
container lid 210
and a resealable container cap 260, capable of further assembly with a
container body 202,
204, such as beverage containers commonly in use as aluminum cans for
distribution of a
wide variety of beverages. The invention further includes a resealable
container cap 260
capable of use with a resealable container lid 210, or with a container 200
that includes a
resealable container lid 210, such that the beverage containers could be
purchased without
resealable container caps 260, and could separately purchase resealable
container caps 260
that are then used with the containers 200 that are formed with the
aforementioned cap
receiving socket 230. This way, resealable container caps 260 could be re-
used, repeatedly.
Purchase of resealable container caps 260 separately from the containers 200
would have a
"green" effect, in that the resealable container caps 260 could be washed and
re-used over
and over, thereby reducing waste.
[00482] Another feature of the invention is to provide a resealable container
cap 360, as
illustrated in FIGS. 36 and 37. The resealable container cap 260 and
resealable container cap
360 include a number of similar features. Like features of the resealable
container cap 260
and the resealable container cap 360 are numbered the same except preceded by
the numeral
'3'. The resealable container cap 360 includes the features presented above,
including the cap
bottom surface ramps 394, 395, and 396, and cam groove surfaces 381, 382, and
383. As with
the other embodiments, the resealable container cap 360 has a cap receiving
socket bottom
wall 334 from which the ramps project. A cap sealing ring 365 is provided on
the surface of
the cap receiving socket bottom wall 334 near the periphery thereof. The cap
sealing ring 365
is made of an elastomeric material that is different from the material that
constitutes the
resealable container cap 360, which is preferably made of a hard plastic
material. The
material which forms the cap sealing ring 365 can be injected through ports
into a mold and
formed on the resealable container cap 360 at the same time that the
resealable container cap
360 is being injection molded. Alternatively, the cap sealing ring 365 can be
a separate pre-
formed item that can be adhesively bonded in place after the resealable
container cap 360 is
removed from its mold.
69
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00483] A central sharp projection 241 is formed in the center of the
bottom surface of
the resealable container cap 360, wherein the central sharp projection 241 is
similar to the
sharp centered incising projection 269 described above in design, location and
function.
[00484] An offset projecting incisor 368 is formed along an outer region of
the bottom
surface of the resealable container cap 360, wherein the offset projecting
incisor 368 is
similar to the offset projecting incisor 268 described above in design,
location, and function.
[00485] Any of a variety of thermoplastic elastomers (TPEs) can be used to
make the cap
sealing ring 365, and selection of the precise one is a matter of design
choice, as the
requirements are simply that the material be easy to mold, easily adherent to
the material that
makes up the cap, and to some degree deformable under pressure (in use). Other
materials
could be used if a sealing ring is pre-made and adhesively bonded to the end
face or bottom
wall of the cap. However, molding the ring in place is preferred. As for TPEs,
they are
sometimes referred to as thermoplastic rubbers, and are in a class of
copolymers or a mixture
of polymers which consist of both thermoplastic and elastomeric properties.
They are
particularly suitable for injection molding, which is the preferred way to
form the cap sealing
ring 365 on the face of the resealable container cap 360.
[00486] It is noted that in FIG. 38, there are two ramps 390, 391 illustrated
as opposed to
three, which are found in the other embodiments. Essentially any number of
ramps can be
employed, but two or three are more preferred for reasons that two or three
can generate an
opening force without requiring too much torque, and they are easier to
manufacture than a
number greater than three. As seen in FIG. 38, a cap used in the embodiment of
FIG. 38 has
two ramps on the lower end face that arc shaped and positioned compatibly with
the socket
bottom panel ramps 390 and 391 shown in FIG. 38.
[00487] The resealable container cap 360 operates in the same way as the caps
of previous
embodiments, in that the consumer turns the cap in one direction to open the
container, then
turns the resealable container cap 360 in the opposite direction to remove the
resealable
container cap 360, and then the resealable container cap 360 is re-inserted
into the cap
receiving socket 230 and turned in the first, container-opening direction
until the resealable
container cap 360 is fully seated in the cap receiving socket 230. The
resealable container cap
260 is shown in this fully seated position in FIG. 35, for resealing the
container 200, in which
the bottom surface 264 of the resealable container cap 260 presses against the
cap receiving
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
socket bottom wall 234 of the cap receiving socket 230 to form a sealing
engagement
between the cap receiving socket 230 and the cap. With the embodiment of
resealable
container cap 360 that includes the sealing ring 367, in this position, the
cap sealing ring 365
is pressed against the cap receiving socket bottom wall 234 of the cap
receiving socket 230 to
enhance the sealing relationship between the cap receiving socket 230 and the
resealable
container cap 360. Contact between a hard surface, i.e., the metal material
that makes up the
cap receiving socket 230, and a relatively softer material, i.e., the
elastomeric material that
makes up the cap sealing ring 365, will ensure a better seal for the contents
of the container
200. This is particularly useful when it comes to carbonated beverages, such
as sodas, beers,
and the like.
[00488] In the previously described embodiments, the cap is provided with a
resealable
container cap handle or grip element 174, as seen in FIGS. 10, 11 and 13a, for
example. An
alternative embodiment of a resealable container cap grip element 374 is shown
in FIGS. 39
and 40, in which the resealable container cap grip element 474 includes two
parallel
resealable container cap grip element first cross member 476 and 478, spaced
apart by an
amount sufficient to fit a force enhancing, or grip enhancing implement 479,
such as a coin or
other object made of a material that is rigid and strong enough to transfer
torque from the
consumer's hand to the resealable container cap 460. It is understood that the
larger the
diameter of the coin or other object, the greater the force that can be
transmitted to the
resealable container cap 460. The container 300 can be sold as an assembly
which includes
the resealable container cap 460 and the implement (coin) 479 (assuming it is
not a coin), a
subassembly including the resealable container lid 410, resealable container
cap 460 and grip
enhancing implement 479 (without the container body and sealed contents), or
the resealable
container cap 460 can be sold by itself. For ease of storage and
transportation, and as a cost
saving, it is preferable not to sell or package a grip enhancing implement 479
with the
container 400 or resealable container cap 460, and/or lid/cap assembly.
[00489] Referring now to FIG. 41, another aspect of the invention includes
making the
score line which defines the tear panel or panels in a way that enhances the
opening or
fracturing ability of the score line. As seen in FIG. 41, a resealable
container lid 410 includes
a cap receiving socket bottom wall 434 which includes a cap receiving socket
bottom wall
434. The cap receiving socket bottom wall 434 includes three socket bottom
panel ramps 490,
491 and 492, and a cap receiving socket bottom panel tear panel 438 defined by
a cap
71
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
receiving socket bottom panel circular score line 436. The cap receiving
socket bottom panel
circular score line 436, as in one of the previous embodiments, is in the form
of a loop, not
quite fully disposed, so that a hinge is defined between the opposite ends of
the cap receiving
socket bottom panel circular score line 436. The cap receiving socket bottom
panel circular
score line 436 is made during the formation steps that create the resealable
container lid 410,
which in the case of beverage cans, is made of 0.008 inch thick material. The
score line 436
is typically 0.004 inch deep, so that the thickness of the lid 410 under the
score line 436 is
typically about 0.004 inch thick for aluminum beverage cans. The thinning of
the material
occurs during pressing of the lid 410, and in essence, the material which
comprises the lid
410 is deformed and flows to create a thinned area beneath the score line 436.
[00490] Using the same principals of material flow or deformation during the
pressing
steps, a score line thinned fracture initiation region 437 is formed at one
end of the cap
receiving socket bottom panel circular score line 436 where one of the ramps
394, 395. 396 in
conjunction with ramps 490, 491, 492 will impinge upon the score line 436. At
the beginning
of the opening process, the ramps 394, 395, 396 in conjunction with ramps 490,
491, 492
push on the flared, score line thinned fracture initiation region 437. which
has been thinned
essentially to the thickness of the sidewall 102, 202 of the container 100,
200, in the case of
an aluminum can. In other words, the entire area of the puncture area is
thinned relative to the
surrounding surface of the lid 410 to make it easier to puncture or break the
score line 436.
Once the score line 436 is broken at the puncture area 437, the break will
propagate more
readily and predictably around the score line 436 to ease the opening of the
container 100,
200. Although the score line thinned fracture initiation region 437 is
thinner, and thus
potentially more vulnerable to accidental opening, it is no thinner than the
sidewall of the
beverage container and thus capable of withstanding internal pressures. It is
also shielded
from accidental external rupture by means of the cap 460 when seated in the
socket 430.
[00491] Each embodiment described herein has referred to a tear panel, such as
cap
receiving socket bottom panel tear panel 138, as that part of the bottom wall
of the socket that
is defined by a circular or loop-shaped score line. This tear panel can also
be described as a
"frangible area" because it breaks away from the rest of the bottom wall 138,
238, 338. 438
when the cap 160, 260, 360, 460 descends into the socket 130, 230, 330, 430.
It is not
required, however, for the tear panel 138, 238, 338, 438 or frangible area to
be substantially
circular or looped in shape, and indeed, a second illustrated embodiment is
shown in FIG. 38.
72
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
While all other aspects of the resealable container lid 310 are the same as in
previous
embodiments, including a cap receiving socket 330 having a cap receiving
socket bottom
wall 334, the bottom wall 334 is provided with an cap receiving socket bottom
panel "S"
shaped score line 344 which, when fractured by operation of the down movement
of the cap
and engagement of socket bottom panel ramp 390 and 391, the fracture forms two
separate
tear panels 338 which are pushed inwardly during the opening operation, with
the two tear
panels 338 being connected to the can by a hinge area 339 on opposite sides of
the cap
receiving socket bottom wall 334. During the opening process, the sharp
protrusion in the
middle of the bottom wall of the cap will puncture the center of the score
line 344 at a score
line fracture thinned initiation region 346. At about the same time, the ramps
390, 391, 392,
393 of the cap receiving socket 330 and the ramps 394, 395, 396 of the
resealable container
cap 360 cooperate to push the tear panels 338 at locations opposite what will
become the
hinges 339. in essentially the "loop" portions of the cap receiving socket
bottom panel "S"
shaped score line 344. Simultaneously, two tear panels 338 are formed and
pushed into the
interior of the container 100, 200.
[00492] During opening and closing operations, the resealable container cap
handle or grip
element 274, 474 is turned preferably ninety degrees (90 ) in one direction,
and then to
withdraw the resealable container cap 260, 360, 460 from the socket, the grip
274, 474 is
turned ninety degrees (90') in the opposite direction, to the beginning point.
In order to
remove the resealable container cap 260, 360, 460 altogether from the lid, the
grip is turned
approximately another ten degrees (10 ) until the grooves and protrusions are
separated and
the resealable container cap 260, 360, 460 is free to be lifted upwardly away
from the
container. Different combinations of embossed ramps 390, 392 and de-bossed
ramps 391,
393, and different numbers of ramps, can be employed to achieve the desired
effect. The
space between the resealable container cap 260, 360, 460 and the cap receiving
socket bottom
wall 234, 334 of the cap receiving socket 230, 330, 430 is equal to the length
of linear travel
when the resealable container cap 260, 360, 460 is operated between the
transport and
open/resealed positions (in the case of aluminum beverage cans, approximately
0.055 inches).
With the use of ramps that are embossed on the tear panel 238, 338, 438 that
distance can be
doubled, forcing the tear panel 238, 338, 438 to fold on its hinge 239, 339,
439 further away
from the opening.
73
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00493] In all cases using ramps, it is preferred that the peak height of the
ramps be
disposed near or in close proximity to the hinge, as this will help push the
tear panel 238,
338, 438 out of the way when the cap's cam body pushes through the opening.
The ramps
help propagate the ruptured score line along its length. There are
corresponding ramps or
other structures on the bottom of the cap that will interface with ramps on
the tear panel 238,
338, 438 or panels. All ramps are embossed (rise up from the bottom socket
surface), but they
could equally be de-bossed ramps 391, 393 that start below the bottom socket
surface and
continue up the embossed ramp 390, 392. If the respective ramp on the cap
starts inside the
debossed ramp on the lid 210, 310, 410, during operation the effective linear
travel of the cap
260, 360 460 can be doubled, tripled, and perhaps quadrupled.
[00494] A resealable container lid 510, illustrated in FIGS. 42 through 78, is
another
exemplary variant of the resealable container lid concepts previously
described herein. The
resealable container lid 510 (detailed in FIGS. 42 through 44) and the
resealable container
cap 560 (detailed in FIGS. 45 through 47) include a portion of features that
are similar to
those of the resealable container lid 110 and resealable container lid 210 and
those of the
resealable container cap 160 and resealable container cap 260, respectively.

formed
having a generally "U" shape, extending downward from the cap receiving socket
cylindrical
sidewall 532, then radially inward arching from a downward direction to an
upward direction,
and extending upward where the peripheral countersink 526 transitions into a
peripheral edge
of the cap receiving socket bottom wall 534. The peripheral countersink 526
can be used to
reference a lower peripheral edge.
[00498] The peripheral countersink 526 extends downward below an upper surface
of the
cap receiving socket bottom wall 534. The peripheral countersink 526 provides
a clearance
for a lower region of a resealable container cap cylindrical exterior sidewall
562 of the

hinge 539. At least
one end can be configured extending outward from an interior region or cap
receiving socket
bottom panel tear panel 538 defined by the cap receiving socket bottom panel
circular score
line 536. The at least one outward extending end of the cap receiving socket
bottom panel
circular score line 536 deters against tearing of the material between the two
ends of the cap
receiving socket bottom panel circular score line 536. It is understood that
the preferred cap
receiving socket bottom panel circular score line 536 would include a
configuration where
both ends include the outward extending formation. The outward extending
formation can be
linear, arched, or of any other suitable shape. In the exemplary embodiment,
the cap receiving
socket bottom panel tear panel 538 is designed to open when the resealable
container cap 560
is rotated in a counterclockwise direction, wherein the opening is defined as
a dispensing
aperture. The dispensing aperture can be sized to dispense a beverage and/or a
food product,
wherein the beverage and/or food product are collectively referred to as
comestible. The
exemplary embodiment is directed towards a container adapted for retaining,
distributing, and
consuming a beverage, such as water, carbonated drinks, fruit drinks, milk,
beer, wine, and
the like. It is understood that the same container lid 510 can be used for
smaller food
products, such as peanuts and other nuts, candy, mints, gumdrops, confections,
jelly beans,
condiments, soups, oils, spices, powdered products (baking soda, sugar,
flour), and the like.
[00501] A seaming chuck shoulder 524 can be folined about a central portion of
the
vertical wall, segmenting the wall into a seaming chuck wall 522 (upper
portion) and a cap
receiving socket cylindrical sidewall 532 (lower portion). The seaming chuck
shoulder 524
can be considered as an upper peripheral edge of the cap receiving socket
cylindrical sidewall
532. A plurality of cam tracks 552, 554, 556 is formed within the cap
receiving socket
cylindrical sidewall 532. The plurality of cam tracks 552, 554, 556 is
spatially arranged about
the cap receiving socket cylindrical sidewall 532. The plurality of cam tracks
552, 554, 556
76
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
run generally horizontally, having slight upward and/or downward deviations to
accomplish
upward and/or downward motions of the resealable container cap 560. The cam
tracks 552,
554, 556, provide several functions, including rotational and axial motions
between the
resealable container lid 510 and the resealable container cap 560,
reinforcement of the
vertical wall, a retention mechanism for retaining the resealable container
cap 560 within the
cap receiving socket of the resealable container lid 510, and other functions.
The cam tracks
552, 554, 556 are segmented functionally into a plurality of sections, as
shown in FIGS. 52
and 53. Details of the plurality of sections of the cam tracks 552, 554, 556
will be described
later herein. The cam tracks 552, 554, 556 are preferably formed as embossed
features
extending inward from the cap receiving socket cylindrical sidewall 532. An
inter-cam relief
section 551, 555, 553 extends between adjacent ends of adjacent cam tracks
552, 554, 556.
The inter-cam relief sections 551. 555. 553 enable passage of a respective cam
follower 581,
582, 583 of the resealable container cap 560 from a position above the cam
tracks 552, 554,
556 to a position below the cam tracks 552, 554, 556.
[00502] A resealable container lid upper surface reinforcement formation 518
can be
included and would be formed as either an embossed feature or a debossed
feature within the
cap receiving socket bottom wall 534. The resealable container lid upper
surface
reinforcement formation 518 is defined by a socket bottom wall to surface
reinforcement
formation transition 541. The cap receiving socket bottom panel tear panel 538
would be
located within the resealable container lid upper surface reinforcement
formation 518. The
resealable container lid upper surface reinforcement formation 518 would be
shaped to
support the material of the reseal able container lid upper surface
reinforcement formation 518
adjacent to the cap receiving socket bottom panel circular score line 536 to
increase the
efficiency of the propagation of the fracture when the opening force is
applied by the
resealable container cap 560 onto the associated features of the cap receiving
socket bottom
panel tear panel 538. In addition, the resealable container lid upper surface
reinforcement
formation 518 provides a clearance for an incisor deboss panel 566 on the
resealable
container cap 560 and the resealable container lid upper surface reinforcement
formation 518
lowers the top surfaces of the lead in supplemental score fracture propagation
and tear panel
support boss 597, the tear panel reinforcing boss 598, and the finishing score
fracture
propagation and tear panel fold urging boss 593 of the cap receiving socket
bottom panel tear
panel 538 resulting in a clearance to the bottom surface of the resealable

traversing wall 564 of the resealable container cap 560. The incisor deboss
panel 566 is
77
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
described as such as when viewing from an exterior surface of a resealable
container cap 560
formed from a single sheet of material, the incisor deboss panel 566 appears
as a recession
extending downward from the resealable container cap planar traversing wall
564. In an
alternative description, the incisor deboss panel 566 can be referred to as an
incisor platform
566, as the incisor platform 566 extends downward from a bottom surface of the
resealable
container cap planar traversing wall 564.
[00503] The resealable container lid 510 can include one or more features to
reinforce
desired areas of the resealable container lid 510.
[00504] Reinforcement features can be integrated into the cap receiving socket

any of several
functions, including retention of a shape of the associated segment of the
resealable container
lid 510, movement between the resealable container cap 560 and the resealable
container lid
510, reinforcement during initiation and/or propagation of a fracture of a cap
receiving socket
bottom panel circular score line 536, clearance for features during operation,
retention of the
resealable container cap 560 within the cap receiving socket of the resealable
container lid
510, and the like.
[00505] The seaming chuck shoulder 524 provides some rigidity to the vertical
sidewall.
The cam tracks 552, 554, 556 provide additional rigidity to the vertical
sidewall. The
peripheral countersink 526 provides support about the lower edge of the
vertical sidewall and
the peripheral edge of the cap receiving socket bottom wall 534. The
peripheral countersink
526 introduces some flexibility between the lower edge of the vertical
sidewall and the
peripheral edge of the cap receiving socket bottom wall 534, which will be
described in more
detail when discussing a retort process.
[00506] As stated above, the socket bottom wall to surface reinforcement
formation
transition 541 (defining the resealable container lid upper surface
reinforcement formation
518) supports the portion of the resealable container lid upper surface
reinforcement
formation 518 adjacent to the cap receiving socket bottom panel circular score
line 536 to
increase the efficiency of the propagation of the fracture when the opening
force is applied by
the resealable container cap 560 onto the associated features of the cap
receiving socket

WO 2017/151419 PCMJS2017/019274
[00507] An incisor pathway channel 517 can be formed within the resealable
container lid
upper surface reinforcement formation 518. The incisor pathway channel 517 is
preferably
formed having a semi-circular, debossed shape concentric with an axis of
rotation of the
resealable container cap 560. One end of the incisor pathway channel 517
terminates at an
incisor channel to tear panel surface transition 592, wherein the incisor
channel to tear panel
surface transition 592 is located proximate and/or abutting a fracture
initiating region of a cap
receiving socket bottom panel circular score line 536. The incisor pathway
channel 517
provides several functions, including increasing a rigidity of the resealable
container lid
upper surface reinforcement formation 518 and providing a clearance for an
incisor 568
during rotation of the resealable container cap resealable container cap 560,
wherein the
offset projecting incisor 568 extends downward from a lower surface of the
resealable
container cap 560.
[00508] The exemplary embodiment includes a series of ribs 593. 597, 598 for
reinforcing
the cap receiving socket bottom panel tear panel 538. These formations
reinforce the cap
receiving socket bottom panel tear panel 538 in both a radial direction and a
tangential
direction respective to a rotational motion of the resealable container cap
560. The series of
ribs 593, 597, 598 transfers and distributes a force applied by features of
the resealable
container cap 560 across the cap receiving socket bottom panel tear panel 538,
directing the
applied force to the cap receiving socket bottom panel circular score line
536, propagating a
fracturing of the cap receiving socket bottom panel circular score line 536
along a length of
the cap receiving socket bottom panel circular score line 536.
[00509] In addition to the above described reinforcing features, the lower
edge of the
resealable container cap cylindrical exterior sidewall 562 can be rolled to
reinforce the
circumferential lower edge thereof, as well as eliminating any sharp edges of
the resealable
container cap 560.
[00510] The resealable container cap 560 can be formed in any suitable
configuration,
with several variations of the container cap being described herein. Each of
the variants of the
container caps can be fabricated of any suitable metal, aluminum, steel,
plastic, composite
materials, fiber reinforced plastics, or any other suitable material. The

exterior sidewall
562. The upward extending resealable container cap cylindrical interior
sidewall 563 and the
downward extending resealable container cap cylindrical exterior sidewall 562
are generally
perpendicular to a resealable container cap planar traversing wall 564.
[00512] A cylindrical sidewall inverted countersink 570 is formed about an
upper end of
the vertical sidewall, the cylindrical sidewall inverted countersink 570 being
a transition
between the resealable container cap cylindrical interior sidewall 563 and the
resealable
container cap cylindrical exterior sidewall 562. The cylindrical sidewall
inverted countersink
570 can be formed having an inverted "U" shape. The resealable container cap
cylindrical
exterior sidewall 562 is preferably dimensioned so that it fits within a
generally vertical
clearance between the proximal surfaces of the cam tracks 552, 554, 556 and
the peripheral
edge of the cap receiving socket bottom wall 534 (essentially, an inner wall
of the peripheral
countersink 526). Additionally, the resealable container cap cylindrical
exterior sidewall 562
is preferably designed so that it curves out towards the cap receiving socket
cylindrical
sidewall 532, closing the gap created between the cap receiving socket
cylindrical sidewall
532 and resealable container cap cylindrical exterior sidewall 562 to provide
clearance for the
cam tracks 552, 554, 556. It is understood that by closing this gap the
container lid assembly
can decrease the possibility of contaminants entering the gap between the cap
receiving
socket cylindrical sidewall 532 and resealable container cap cylindrical
exterior sidewall 562.
[00513] An offset projecting incisor 568 extends downward from a bottom
surface of the
resealable container cap planar traversing wall 564. The offset projecting
incisor 568 can be
located within a incisor deboss panel 566, wherein the incisor deboss panel
566 is a &bossed
feature providing several functions, including lowering the offset projecting
incisor 568,
reinforcing an area of the material surrounding the offset projecting incisor
568, a distributed

[00515] A series of cam followers 581, 582, 583 are spatially arranged along a
lower edge
of the resealable container cap cylindrical exterior sidewall 562. The cam
followers 581, 582,
583 are preferably formed using any suitable metal forming process, such as
crimping
process. The cam followers 581, 582, 583 would be sized and spatially arranged
and located
to be in alignment with the respective inter-cam relief sections 551, 555,
553. The cam
followers 581, 582. 583 are sized and spatially arranged to pass through each
respective inter-
cam relief section 551, 555, 553 for engagement with a lower surface of the
respective cam
track 552, 554, 556. The interaction between the cam followers 581, 582, 583
and the
respective cam track 552, 554, 556 converts a rotational motion of the
resealable container
cap 560 within the cap receiving socket of the resealable container lid 510
into at least one of
an axial motion and an axial force applicator. The peripheral countersink 526
of the
resealable container lid 510 is sized and shaped to receive the bottom edge of
resealable
container cap cylindrical exterior sidewall 562 and the cam followers 581,
582, 583 formed
on the bottom edge of resealable container cap cylindrical exterior sidewall
562.
[00516] At least one resealable container cap grip element 574 is formed
extending
upward from the top surface of the resealable container cap planar traversing
wall 564 of the
resealable container cap 560. The resealable container cap grip element 574
can be formed
having any suitable shape. In a preferred embodiment, the resealable container
cap grip
element 574 would be of a height that retains a top edge of the resealable
container cap grip
element 574 at or below a top edge or surface of the seam of the container
(container body
and lid assembly seam 509 of FIG. 90). The resealable container cap planar
traversing wall
564 is recessed within a cavity defined by the resealable container cap
cylindrical interior
sidewall 563, wherein the recessed resealable container cap planar traversing
wall 564
enables the resealable container cap grip element 574 to project upward
therefrom, while
retaining a minimum overall height from the bottom of the resealable container
cap 560.
[00517] The resealable container cap grip element 574 would include at least
one cap grip
element force application surface 575. The cap grip element force application
surface 575
would be sized to ergonomically and adequately support a force applied by the
end user.
[00518] The user would grip each at least one cap grip element force
application surface
575 to apply a force to the resealable container cap 560. The force is
translated into a
rotational or torsional force for urging the resealable container cap 560 into
a
counterclockwise (score line fracturing) motion or a clockwise (closing)
motion. In more
81
CA 03015350 2018-08-20

detail, the cam tracks 552, 554, 556 are segmented into a plurality of
functional sections, as
best shown in FIGS. 52 and 53. Initially, each cam follower 581, 582, 583 is
aligned with the
respective inter-cam relief section 551, 555, 553, as best shown in FIGS. 44,
48. 49, and 54.
The resealable container cap 560 is inserted into the cap receiving socket of
the resealable
container lid 510, wherein the cam followers 581, 582, 583 pass through the
respective inter-
cam relief sections 551, 555, 553, creating a container lid assembly as shown
in FIG. 50. In
the exemplary version, the resealable container lid 510 and the resealable
container cap 560
are geometrically related with one another. The first formed cam follower 581
is aligned with
the first inter-cam relief section 551 during initial assembly of the
resealable container cap
560 into the cap receiving socket of the resealable container lid resealable
container lid 510,
as shown in the side elevation exploded assembly view of FIG. 54.
Additionally, this
alignment inserts the offset projecting incisor 568 into the incisor pathway
channel 517, as
shown in FIG. 55 and 56.
[00519] The assembly requires a significant downward force in combination with
a
counterclockwise rotation, compressing a cap sealing ring 565 sufficiently
enough to locate
the first formed cam follower 581 along a bottom edge of the cam track
assembly / locking
detent segment 552A of the first socket cam track 552. The significant
downward force
compresses the cap sealing ring 565, as shown in FIGS. 55, 56, 57. The initial
contact is
illustrated in FIG. 56, where the cap sealing ring 565 is in contact with the
top surface of the
cap receiving socket bottom wall 534, but not yet compressed. During
application of the
significant downward force, the cap sealing ring 565 is compressed, as
illustrated in FIG. 57.
The cam track assembly / locking detent segment 552A is configured being the
lowest point
of the cam track 552. Continuing with the counterclockwise rotation of the cap
will transfer
the first formed cam follower 581 into cam track initial / resealed segment
552B, which
allows decompression of the cap sealing ring 565 (as shown in FIG. 68), as
shown in the side
elevation exploded assembly view of FIG. 58. Additionally, the configuration
of the cam
tracks 552, 554, 556 retain the resealable container cap 560 with the cap
receiving socket of
the resealable container lid 510 by the cam followers 581, 582, 583.
[00520] The cam track assembly / locking detent segment 552A retains the
resealable
container cap 560 within the cap receiving socket of the resealable container
lid 510, when
subjected to a clockwise motion. The offset projecting incisor 568 butts up
against the incisor
channel to tear panel surface transition 592 to retain the resealable

the cap receiving socket of the resealable container lid 510, when subjected
to a continuing
counterclockwise motion. Registration between the offset projecting incisor
568 and the
incisor channel to tear panel surface transition 592 is best shown in FIGS. 60
and 61. Thus
retaining the resealable container cap 560 within the cap receiving socket
enabling only a
small rotational motion thereof. It is understood that the design can be such
to limit any
motion to effectively eliminating any play between a counterclockwise motion
and a
clockwise motion.
[00521] The initial assembly step is adapted for completion by a mechanical
device, such
as an assembly machine. The forces required are designed to deter
accomplishment of the
initial assembly step by an individual. The subsequent steps are adapted to be
accomplished
by the end user.
[00522] The following describes the container lid opening sequence, which is
directed
towards completion by the end user. Continuing with a counterclockwise
rotation of the
resealable container cap 560, from a position where the first formed cam
follower 581 is
engaged with the cam track initial / resealed segment 552B, the continuing
motion causes the
offset projecting incisor 568 to impinge upon the incisor channel to tear
panel surface
transition 592, initializing a fracture of the cap receiving socket bottom
panel circular score
line 536, as shown in FIGS. 61, 67, 71.
[00523] As the rotation continues, the first formed cam follower 581
transitions from the
cam track initial / resealed segment 552B to a cam track height transition
segment 552C, as
best shown in FIGS. 62, 68, 72. During this transition, the bottom surface of
the offset
projecting incisor 568 begins to ride upon a top surface of the incisor
channel to tear panel
surface transition 592, wherein the offset projecting incisor 568 begins to
force the cap
receiving socket bottom panel tear panel 538 into the resealable container
500. Additionally,
the bottom surface of the incisor deboss panel 566 begins to ride upon a top
surface of the
lead in supplemental score fracture propagation and tear panel support boss
597, wherein the
incisor deboss panel 566 performs at least one function of propagating the
fracture of the cap
receiving socket bottom panel circular score line 536 and traversely
distributes the axial force
applied by the offset projecting incisor 568 to the incisor channel to tear
panel surface
transition 592 out to the bifurcated score line fracture 536. Further, the
resealable container
cap 560 separates slightly from the resealable container lid 510 in an axial
direction,
separating cap sealing ring 565 from contact with the upper surface of the cap
receiving
83
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
socket bottom wall 534 of the resealable container lid 510. This separation
decreases or
eliminates any parasitic drag or continued friction between the cap sealing
ring 565 and the
upper surface of the cap receiving socket bottom wall 534 and enables
continued
counterclockwise rotation of the resealable container cap 560 to propagate the
fracturing of
the cap receiving socket bottom panel circular score line 536. Additionally,
this separation
allows the venting of the pressurized gases released from the resealable
container 500 when
the offset projecting incisor 568 impinged upon the incisor channel to tear
panel surface
transition 592, initializing the fracture of the cap receiving socket bottom
panel circular score
line 536, in order to avoid the resealable container cap 560 from becoming a
projectile if
released from the container lid socket while still retaining pressure from the
opened
resealable container 500. As the rotation continues, the first formed cam
follower 581
transitions from the cam track height transition segment 552C to a cam track
operating
segment 552D, as best shown in FIGS. 63, 69, 73. During this transition, the
bottom surface
of the offset projecting incisor 568 begins to ride upon a top surface of the
tear panel surface
incisor pathway 591, continuing to generate an axial force for propagating the
bifurcated
score line fracture 536 and further separating the cap sealing ring 565 and
the upper surface
of the cap receiving socket bottom wall 534. Additionally, the incisor deboss
panel 566 in
conjunction with the arrangement the ribbed support structures lead in
supplemental score
fracture propagation and tear panel support boss 597, 598, 593 on the cap
receiving socket
bottom panel tear panel 538, further the propagation of the fracture of the
cap receiving
socket bottom panel circular score line 536 by distributing the applied
loading force from the
resealable container cap 560, as shown in FIG. 69 and 73. In addition to
propagating the
fracture of the cap receiving socket bottom panel circular score line 536, the
process also
folds the cap receiving socket bottom panel tear panel 538 about the tear
panel hinge 539,
away from the resealable container lid upper surface reinforcement formation
518. The load
is sustained by the cam followers 581. 582, 583 riding against the bottom
surface of the
respective cam track 552, 554, 556.
[00524] As the rotation continues, the offset projecting incisor 568 rides up
tear panel
surface incisor pathway to tear panel fold boss transition 590, as shown in
FIGS. 64, 70, and
74, and subsequently transitions onto the finishing score fracture propagation
and tear panel
fold urging boss 593, as shown in FIGS. 65 and 75. As the transition occurs,
the incisor
deboss panel 566 separates from the top surface of the ribbed support
structure 597, 598, 593.
84
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00525] Nearing the end of the rotational container lid opening sequence, just
prior to the
transition of the first formed cam follower 581 between the cam track
operating segment
552D to a cam track cam follower leader section 552E, shown in FIGS. 73. 74,
the offset
projecting incisor 568 impinges upon finishing score fracture propagation and
tear panel fold
urging boss 593 to finalize the folding of the cap receiving socket bottom
panel tear panel
538 into the interior of the resealable container 500, as shown in FIGS. 65
and 75. Following
the conclusion of the opening sequence, the cam followers 581, 582, 583
transition to a cam
track cam follower leader section 552E, as shown in FIG. 75, where the cam
followers 581,
582, 583 are guided into the adjacent inter-cam relief section 551, 555, 553,
enabling removal
of the resealable container cap 560 from the resealable container lid 510.
More specifically,
the conclusion of the opening sequence locates the first formed cam follower
581 within the
third inter-cam relief section 555, enabling the axial withdrawal of the
resealable container
cap 560 from the resealable container lid 510, as shown in FIG. 76.
[00526] The shape of the cam tracks 552, 554, 556, more specifically, the cam
track cam
follower leader section 552E, is designed such to provide a clearance between
the bottom of
the offset projecting incisor 568 and the top surface of the resealable
container lid upper
surface reinforcement formation 518 to avoid any binding or other interference
of the rotation
of the resealable container cap 560. The combination of the cam track assembly
/ locking
detent segment 552A and cam track cam follower leader section 552E ensures the
reinstallation of the resealable container cap 560 into the cap receiving
socket is only in a
clockwise direction. Additionally, the revised, opened configuration of the
resealable
container lid 510 enables the user to insert the resealable container cap 560
into the cap
receiving socket to reseal the resealable container 500 in any of the three
potential
orientations. The incisor pathway channel 517 provides clearance for the
offset projecting
incisor 568 in any orientation. The associated cam follower 581, 582, 583 is
rotated to engage
with the respective sealing section of the cam track 552, 554, 556 (as
referenced by cam track
initial / resealed segment 552B of the first socket cam track 552), causing
the cap sealing ring
565 to compress against the top surface of the cap receiving socket bottom
wall 534,
providing an air and liquid tight seal therebetween.
[00527] In addition to the operational features, the resealable container cap
560 can
include a tamper indicator, such as the off-center tamper indicator feature
528, shown in
FIGS. 45-47, and shown functioning in FIGS. 77, 78. The off-center tamper
indicator feature
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
528 includes an off-center tamper indicator operation element 529, wherein the
off-center
tamper indicator operation element 529 mechanically operates the off-center
tamper indicator
feature 528. The off-center tamper indicator operation element 529 contacts
the opposing
surface of the resealable container lid upper surface reinforcement formation
518. The
resealable container lid upper surface reinforcement formation 518 maintains a
rigid (non-
pliable) form when the resealable container 500 is in a sealed (unopened)
condition, as shown
in FIG. 77. The rigidity is provided by an internal pressure within the
resealable container
500. The rigidity of the resealable container lid upper surface reinforcement
formation 518
supports the off-center tamper indicator operation element 529, which in turn
inhibits any
motion of the off-center tamper indicator feature 528. This maintains the off-
center tamper
indicator feature 528 in position, disabling any potential for the off-center
tamper indicator
feature 528 to -report", wherein the "report" is the ability of the off-center
tamper indicator
feature 528 to flex, which preferably generates an audible and/or tactile
response. When the
resealable container 500 is breached, such as by the opening sequence
previously described
herein, the supporting pressure from within the resealable container 500 is
reduced or
removed, thus removing any support provided by the resealable container lid
upper surface
reinforcement formation 518 to the off-center tamper indicator operation
element 529,
resulting in a flexible condition of the off-center tamper indicator feature
528, now allowing
the off-center tamper indicator feature 528 to "report", as shown in FIG. 78.
[00528] Another feature of the configuration of the resealable container lid
510 and
resealable container cap 560 is an anti-missiling function. Missiling may
occur upon an initial
fracture of the cap receiving socket bottom panel circular score line 536,
releasing stored
pressure from within the resealable container 500. In a condition where the
resealable
container cap 560 retains a seal against the resealable container lid 510 and
the resealable
container lid 510 is breached, the pressure released from the resealable
container 500 could
potentially cause the resealable container cap 560 to become a projectile. The
anti-missiling
feature is created by a separation between the cap sealing ring 565 and the
top surface of the
cap receiving socket bottom wall 534 while the resealable container cap 560
remains in
engagement with the resealable container lid 510 during the initial opening
sequence of the
resealable container 500, thus providing a pathway for release of pressure.
86
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00529] As previously mentioned, the resealable container cap 560 can be
designed in any
of a variety of configurations. A resealable container cap 660, illustrated in
FIGS. 79 through
81 and 86 through 90, is one exemplary variant of the resealable container cap
560.
[00530] The resealable container cap 660 includes features that are similar to
those of the
resealable container cap 560. Like features of the resealable container cap
660 and the
resealable container cap 560 are numbered the same except preceded by the
numeral '6'. The
significant distinction of the resealable container cap 660 is the location of
the concentric
tamper indicator feature 628. The off-center tamper indicator feature 528 is
formed in an off-
centered location respective to a centroid of the resealable container cap
560. Conversely, the
concentric tamper indicator feature 628 is formed in a concentric about the
centroid of the
resealable container cap 660. The centered location of the concentric tamper
indicator feature
628, and more specifically, the concentric tamper indicator operation element
629 of the
concentric tamper indicator feature 628, is located to contact the resealable
container lid
upper surface reinforcement formation 518 of the resealable container lid 510,
as illustrated
in FIG. 80. The cap receiving socket bottom panel circular score line 536 is
designed to
ensure that the cap receiving socket bottom panel tear panel 538 is off-
centered to retain
adequate support from the resealable container lid upper surface reinforcement
formation 518
to the concentric tamper indicator operation element 629. When the resealable
container 500
is sealed (unopened), the concentric tamper indicator operation element 629
contacts and is
supported by the resealable container lid upper surface reinforcement
formation 518, as
shown in FIG. 80. The pressure within the container maintains a rigidity of
the cap receiving
socket bottom wall 534, including the resealable container lid upper surface
reinforcement
formation 518. The pressure maintains a convex or bulged shape of the cap
receiving socket
bottom wall 534, including the resealable container lid upper surface
reinforcement formation
518. When the resealable container 500 is breached, the release of the
pressure from within
the interior of the container eliminates the support of the cap receiving
socket bottom wall
534, including support of the resealable container lid upper surface
reinforcement formation
518. This results in a creation of a tamper indicator operation element and
lid surface gap
527, as shown in FIG. 81, the tamper indicator operation element and lid
surface gap 527
extending between the concentric tamper indicator operation element 629 and
the top surface
of the resealable container lid upper surface reinforcement formation 518
and/or a flexibility
of the resealable container lid upper surface reinforcement formation 518.
Either condition
allows the off-center tamper indicator feature 528 to "report" as previously
described above,
87
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
indicating the breach to the end user. Again, the "report" can be a tactile
report, an audible
report, or any other known reporting method.
[00531] An assembly of the resealable container lid 510 onto the container
cylindrical
sidewall 102 was previously introduced, but not fully described. The assembly
process is
described in a series of sequence illustrations shown in FIGS. 82 through 85.
The resealable
container cap 560 can be assembled to the resealable container lid 510 either
prior to
assembly of the resealable container lid 510 onto the container cylindrical
sidewall 102 or
subsequent to the assembly of the resealable container lid 510 onto the
container cylindrical
sidewall 102. In the exemplary assembly process, the resealable container cap
560 is
assembled to the resealable container lid 510 prior to assembling the
resealable container lid
510 onto the container cylindrical sidewall 102, as this configuration does
not introduce
limitations confronted in the process which excludes the resealable container
cap 560.
[00532] A seaming chuck tool 600 is inserted into an interior of the
resealable container lid
510 defined by the interior surface of the seaming chuck wall 522. The
resealable container
lid 510 is seated upon the container seaming panel 106 and the container
seaming wall 108 of
the container cylindrical sidewall 102, as shown in FIGS. 82, 83. The
container seaming wall
108 is a frustum shaped registration surface formed about an opening of the
container
cylindrical sidewall 102. The container seaming panel 106 is an outward
extending radial
flange formed about an opening of the container cylindrical sidewall 102. The
seaming chuck
tool 600 includes a seaming chuck tool conical driving wall 601, a seaming
chuck tool planar
driving surface 602, and a seaming chuck tool cap clearance cavity 603. The
seaming chuck
tool conical driving wall 601 has a male frustum shape that is in
concentric/conical
registration with the seaming chuck wall 522 of the resealable container lid
510 and the
container seaming wall 108 of the container cylindrical sidewall 102, and is
preferably
designed to receive the compression forces applied by the first operation
roller driving
channel first operation roller driving channel 606 of the first operation
roller 604 and the
second / final operation roller driving channel 609 of the second / final
operation roller 607.
The seaming chuck tool planar driving surface 602 is preferably located about
a lower edge
of the seaming chuck tool conical driving wall 601. Alternatively, the seaming
chuck tool
planar driving surface 602 can be formed within a portion of the seaming chuck
tool conical
driving wall 601. The seaming chuck tool planar driving surface 602 is
preferably designed to
provide a compression force to the seaming chuck shoulder 524 without coming
into contact
88
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
with the cylindrical sidewall inverted countersink 570 of the resealable
container cap 560.
The seaming chuck tool cap clearance cavity 603 extends upward into the
seaming chuck tool
600, wherein the seaming chuck tool cap clearance cavity 603 is designed to
provide
clearance for features extending upward from the resealable container cap
planar traversing
wall 564 of the resealable container cap 560, such as a pair of resealable
container cap grip
elements 574. The cylindrical sidewall inverted countersink 570 of the
resealable container
cap 560 is preferably designed and positioned relative to the seaming chuck
shoulder 524 so
that the cylindrical sidewall inverted countersink 570 does not come into
contact with any
part of the seaming chuck tool 600 during the seaming process. The seaming
chuck tool
conical driving wall 601 and the seaming chuck tool planar driving surface 602
apply a
compression force upon the seaming chuck wall 522 and the seaming chuck
shoulder 524 of
the resealable container lid 510 to ensure a bottom surface of the seaming
panel 520 is
properly seated against an upper surface of the container seaming panel 106.
[00533] A first operation roller driving channel first operation roller
driving channel 606,
formed in a contacting surface of the first operation roller 604, rolls the
seaming panel 520
and the respective portion of the container seaming panel 106, as shown in
FIG. 84. The first
operation roller driving channel first operation roller driving channel 606 is
formed as a semi-
circular groove within a cylindrical sidewall of the first operation roller
604. In a preferred
process, the first operation roller 604 rotates about a first operation roller
rotational axis 605
and the seaming chuck tool 600 rotates the container cylindrical sidewall 102
and the
associated resealable container lid 510 against the first operation roller
driving channel first
operation roller driving channel 606 of the first operation roller 604. The
contact between the
first operation roller driving channel first operation roller driving channel
606 and the
seaming panel 520 in conjunction with the resulting forces rolls the
combination of the
seaming panel 520 and the container seaming panel 106 together. Subsequently,
a second /
final operation roller 607, employing a second / final operation roller
driving channel 609 in a
similar manner to the first operation roller driving channel first operation
roller driving
channel 606 of the first operation roller 604 compresses the rolled formation
into a
compressed formation, as shown in FIG. 85. The second / final operation roller
driving
channel 609 is formed as an oblong, rectangular groove within a cylindrical
sidewall of the
second / final operation roller 607.
89
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00534] In a preferred process, the second / final operation roller 607
rotates about a
second (final) operation roller spin axis 608 and the seaming chuck tool 600
rotates the
container cylindrical sidewall 102 and the associated resealable container lid
510 against the
second / final operation roller driving channel 609 of the second / final
operation roller 607.
The contact between the second / final operation roller driving channel 609
and the rolled
version of the seaming panel 520 in conjunction with the resulting forces
compresses the
combination of the seaming panel 520 and the container seaming panel 106
together. The
compressed shape creates a sealed seam between the seaming panel 520 and the
container
seaming panel 106. The completed container assembly is referred to as a
resealable container
500 and the completed seam is referred to as a container body and lid assembly
seam 509, as
shown in FIG. 85.
[00535] Once sealed, the resealable container 500 is subjected to a process
referred to a
retort, where the contents of the resealable container 500 are heated. The
heat increases an
internal pressure within the resealable container 500. The increased pressure
deforms the
resealable container lid 510 of the resealable container 500. More
specifically, because of the
shape of the features of the resealable container 500, the increased pressure
deforms the cap
receiving socket bottom wall 534 of the resealable container lid 510 upward
into a domed or
bulged shape as indicated by the upward directing arrow in FIGS. 86, 87, which
draws the
peripheral edge of cap receiving socket bottom wall 534 (essentially, the
peripheral
countersink 526) inward, as indicated by the pair of radially inwardly
directed arrows located
adjacent to each sectioned view of the peripheral countersink 526. The
resealable container
lid 510 and the resealable container cap 660 are shown in a pre-retort,
original shape in FIG.
86. The resealable container lid 510 and the resealable container cap 660 are
shown in a
deformed, bulged shape during the retort process in FIG. 87. A magnified view
of the
peripheral countersink 526, illustrated in FIG. 88, introduces the deflections
imposed upon
the features of the resealable container lid 510 and the resealable container
cap 660 during the
retort process. Broken tangent lines 611, 613, 615 delineate an original shape
of the
respective assembly segments 610. 612, 614, shown prior to exposure to the
retort process.
Solid tangent lines 621, 623. 625 delineate a reformed shape of the respective
assembly
segments 620, 622, 624, shown during the retort process. The resealable
container lid 510 and
the resealable container cap 660 are shown in a post-retort, residual deformed
shape in FIG.
89.
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00536] In an original shape of the container lid assembly, prior to exposure
to the retort
process, the peripheral countersink 526 is formed having a outer peripheral
countersink wall
pre-retort geometry 610 on an outer, distal region and a inner peripheral
countersink wall pre-
retort geometry 612 on an inner, proximal region. Additionally, the cap
receiving socket
bottom wall 534 is referred to as a cap receiving socket bottom wall post-
retort geometry 624.
The outer peripheral countersink wall pre-retort geometry 610 is formed along
an outer
peripheral countersink wall pre-retort geometry angle delineator 611. The
inner peripheral
countersink wall pre-retort geometry 612 is formed along an inner peripheral
countersink
wall pre-retort geometry angle delineator 613. The cap receiving socket bottom
wall post-
retort geometry 624 is formed along a cap receiving socket bottom wall pre-
retort geometry
angle delineator 615. In a pre-retort condition, the outer peripheral
countersink wall pre-retort
geometry 610 and the inner peripheral countersink wall pre-retort geometry 612
are generally
vertically oriented. Additionally, the cap receiving socket bottom wall pre-
retort geometry
614 is generally planar and substantially horizontally oriented.
[00537] In a shape of the container lid assembly during the retort process,
the outer
peripheral countersink wall pre-retort geometry 610 is reshaped into a outer
peripheral
countersink wall post-retort geometry 620 on the outer, distal region and the
inner peripheral
countersink wall pre-retort geometry 612 is reshaped into a inner peripheral
countersink wall
post-retort geometry 622 on the inner, proximal region of the peripheral
countersink 526.
Additionally, the cap receiving socket bottom wall pre-retort geometry 614 is
reshaped into a
cap receiving socket bottom wall post-retort geometry 624. The outer
peripheral countersink
wall post-retort geometry 620 is formed along an outer peripheral countersink
wall post-retort
geometry angle delineator 621. The inner peripheral countersink wall post-
retort geometry
622 is formed along an inner peripheral countersink wall post-retort geometry
angle
delineator 623. The cap receiving socket bottom wall post-retort geometry 624
is formed
along a cap receiving socket bottom wall post-retort geometry angle delineator
625. During
this process, the cap receiving socket bottom wall pre-retort geometry 614
transitions from a
generally planar shape to a convex or bulged shape, identified as a cap
receiving socket
bottom wall post-retort geometry 624. This geometric condition reduces the
diameter of the
peripheral edge of the cap receiving socket bottom wall 534 (cap receiving
socket bottom
wall pre-retort geometry 614). This reduction in the diameter of the
peripheral edge of the cap
receiving socket bottom wall 534 draws the upper edge of the inner peripheral
countersink
wall pre-retort geometry 612 inward, angling the inner peripheral countersink
wall pre-retort
91
CA 03015350 2018-08-20
WO 2017/151419 PCT/1JS2017/019274
geometry 612 respectively, which is subsequently referred to as a inner
peripheral
countersink wall post-retort geometry 622. The reshaping of the inner
peripheral countersink
wall pre-retort geometry 612 to the inner peripheral countersink wall post-
retort geometry
622 pulls the peripheral countersink 526 inward, impacting the lower edge of
the cap
receiving socket cylindrical sidewall 532. The resulting motion draws the
lower edge of the
outer peripheral countersink wall pre-retort geometry 610 inward, angling the
outer
peripheral countersink wall pre-retort geometry 610 respectively, which is
subsequently
referred to as an outer peripheral countersink wall post-retort geometry 620.
[00538] In a post-retort shape of the resealable container lid 510, the
reshaped assembly
segments 620, 622, 624 permanently retain a portion of the reshaping undergone
during the
retort process.
[00539] The design of the resealable container cap 660, more specifically a
cylindrical
sidewall inverted countersink 670 provides a flexible transition between the
resealable
container cap cylindrical exterior sidewall 662 and resealable container cap
cylindrical
interior sidewall 663, which accommodates a reshaping of the resealable
container cap planar
traversing surface 664 when the resealable container cap 660 is assembled onto
the outer
peripheral countersink wall pre-retort geometry 610. This reshaping results
from a force
applied to the resealable container cap planar traversing surface 664 by the
cap receiving
socket bottom wall 534 on the resealable container lid 510 during the retort
process. A
separation between the resealable container cap planar traversing surface 664
and cap
receiving socket bottom wall 534 may be maintained by the off-center tamper
indicator
operation element 529 being in mechanical contact with the upper surface of
the resealable
container lid upper surface reinforcement formation 518, maintaining the
relative separation
between the resealable container cap planar traversing surface 664 and the cap
receiving
socket bottom wall 534 during the retort process in order to prevent the
offset projecting
incisor 668 from prematurely placing a fracturing forcing upon the cap
receiving socket
bottom panel circular score line 536. Additionally, the reshaping of the cap
receiving socket
cylindrical sidewall 532 during the retort process, more specifically, the
outer peripheral
countersink wall pre-retort geometry 610, impinges cam tracks 552, 554, 556
into the
respective cam followers 581, 582, 583, retaining the assembly of the
resealable container
cap 660 onto the resealable container lid 510 during the maximum deformation
during the
retort process.

[00540] The design of the resealable container cap 660, more specifically, the
resealable
container cap cylindrical exterior sidewall 662 is adapted to accommodate the
changes in
shape of the peripheral countersink 526 of the resealable container lid 510
during and
subsequent to the retort process. The end result enables rotational motion of
the resealable
container cap cylindrical exterior sidewall 662 within the peripheral
countersink 526 by the
consumer after completion of the retort process. This avoids any binding
between the cam
followers 581, 582, 583 within the peripheral countersink 526, while retaining
the cam
followers 581, 582, 583 against the mating surface of the respective cam
tracks 551, 553,
555. It is recognized that the deformation of the cap receiving socket
cylindrical sidewall 532
resulting from the retort process is adapted to enhance the engagement between
the cam
followers 581, 582, 583 and the mating surface of the respective cam tracks
551, 553, 555, as
the deformation decreases the diameter of the lower portion of the 526.
[00541] The resulting post-retort shape is shown in a cross sectioned view of
the resealable
container 500, as presented in FIG. 89.
[00542] The resealable container 500 can include features enabling nesting
between
assemblies 500. as shown in FIG. 90. A container closed bottom wall 504 of the
resealable
container 500 includes a clearance to accommodate upward extending features,
such as the
pair of resealable container cap grip elements 674. A countersink or other
feature can be
formed within the container closed bottom wall 504, wherein the countersink is
shaped and
sized to nest within an interior of the container body and lid assembly seam
509 of the
seaming chuck tool 600.
[00543] Such as the resealable container cap 560 can include variations, the
resealable
container lid 510 is also open to variations in the design. For example, a
resealable container
lid 710, shown in FIGS. 91 through 94, introduces a variation in the layout of
the cap
receiving socket bottom panel circular score line 736 compared to the layout
of the cap
receiving socket bottom panel circular score line 536 of the resealable
container lid 510. The
resealable container lid 710 includes features that are similar to those of
the resealable
container lid 510. Like features of the resealable container lid 710 and the
resealable
container lid 510 are numbered the same except preceded by the numeral '7'. In
the
resealable container lid 510, as best shown in FIG. 44, the cap receiving
socket bottom panel
circular score line 536 is routed through each of the opposing sidewalls of
the incisor
pathway channel 517 and across a bottom surface of the incisor pathway channel
517.
93
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
Conversely, the cap receiving socket bottom panel circular score line 736 is
routed passing
across an upper tangential edge of the associated end (identified as an
incisor channel to tear
panel surface transition 792) of the incisor pathway channel 717, as best
shown in FIG. 93.
The score line fracture thinned initiation region 746 would be formed
extending inward from
an exterior or exposed surface of the resealable container lid upper surface
reinforcement
formation 718, down an end wall on the incisor pathway channel 717
(essentially, the incisor
channel to tear panel surface transition 792). A score line thinned region
seal reinforcement
747 is preferably applied to an opposite or interior surface of the resealable
container lid
upper surface reinforcement formation 718, more specifically, about the region
of the score
line fracture thinned initiation region 746 routed passing across an upper
tangential edge of
the associated end (incisor channel to tear panel surface transition 792) of
the incisor pathway
channel 717, as shown in the underside views presented in FIGS. 92 and 94. The
score line
thinned region seal reinforcement 747 can be of the same material used to form
a cap sealing
ring 565 to optimize fabrication steps and costs. The score line thinned
region seal
reinforcement 747 retains a seal should the score line fracture thinned
initiation region 746
fracture prematurely. Alternatively, the score line fracture thinned
initiation region 746 can
be configured to cut completely though the resealable container lid 510
material substrate,
relying on the score line thinned region seal reinforcement 747 to maintain a
sealed container.
[00544] The cap receiving socket bottom panel circular score line 536, 736 is
commonly
created using a standard single step forming process. A resealable container
lid 810, shown in
FIGS. 95 through 105, introduces a multi-step process for forming a cap
receiving socket
bottom panel circular score line 836. The resealable container lid 810
includes features that
are similar to those of the resealable container lid 510, 710. Like features
of the resealable
container lid 810 and the resealable container lid 510, 710 are numbered the
same except
preceded by the numeral '8', unless otherwise stated. The multi-step process
for forming the
cap receiving socket bottom panel circular score line 836 employs a first
incisor pathway
index formation 894 and an second incisor pathway index formation 896. The
first incisor
pathway index formation 894 is located on a first end of an incisor pathway
channel 817,
wherein the first end includes an incisor channel to tear panel surface
transition 892. The
second incisor pathway index formation 896 is formed at a second end of the
incisor pathway
channel 817, which is preferably located proximate a tear panel hinge 839. The
first incisor
pathway index formation 894 and the second incisor pathway index formation 896
are
formed using a more repeatable and accurate forming process than the process
forming the
94
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
ends of the incisor pathway channel 817. Additionally, the geometric shape of
the indexing
features 894, 896 are such to provide more accurate indexing registration than
the shape of
the ends of the incisor pathway channel incisor pathway channel 817, and to
provide a more
accurate geometric shape to form the cap receiving socket bottom panel
circular score line
836 and respective features. A lid bottom score line thinned formation region
895, introduced
in FIG. 96, can be formed in an opposite or interior surface of the first
incisor pathway index
formation 894, more specifically about the region of the score line fracture
thinned initiation
region 846 of the cap receiving socket bottom panel circular score line 836.
[00545] The multi-step process for forming a cap receiving socket bottom panel
circular
score line 836 is demonstrated in a series of illustrations presented in FIGS.
97 through 105.
Since the scoring process thins the material of the resealable container lid
810, the majority of
the features of the resealable container lid 810 are initially created as
shown in FIG. 97. This
includes the incisor pathway channel 817. The indexing features 894, 896 are
subsequently
formed at the respective ends of the incisor pathway channel 817, as shown in
FIG. 98, using
a lid alignment feature anvil 910A and a lid alignment feature punch tool
960A, introduced in
FIG. 101. The lid alignment feature punch tool 960A includes a first incisor
pathway index
formation punch 994 and a second incisor pathway index formation punch 996
extending
downward from a lid alignment feature punch tool bottom surface 964 of a lid
alignment
feature punch tool body 962. The lid alignment feature anvil 910A includes
features formed
within a cap receiving socket bottom wall anvil 934 of a cap receiving socket
cylindrical
anvil body 932 to adequately support the resealable container lid 810. A
resealable container
lid upper surface reinforcement formation anvil 918 is recessed into the cap
receiving socket
bottom wall anvil 934 to accommodate the resealable container lid upper
surface
reinforcement formation 818. A socket bottom wall to surface reinforcement
formation
transition anvil 941 provides a transition between the cap receiving socket
bottom wall anvil
934 and the resealable container lid upper surface reinforcement formation
anvil 918. An
incisor pathway channel anvil 917 is recessed into the resealable container
lid upper surface
reinforcement formation anvil 918 to accommodate the incisor pathway channel
817. The
shapes of the resealable container lid upper surface reinforcement formation
anvil 918 and
the incisor pathway channel anvil 917 are used as initial registration or
alignment features
between the partially completed resealable container lid 810 and the lid
alignment feature
anvil 910A. A first incisor pathway index formation anvil 993 and a second
incisor pathway
index formation anvil 997 are formed at ends of the incisor pathway channel
anvil 917 for
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
receiving material being deformed by the first incisor pathway index formation
punch 994
and the second incisor pathway index formation punch 996, respectively. A gap
between the
first incisor pathway index formation punch 994 and the first incisor pathway
index
formation anvil 993 is substantially the same as a thickness of the material
of the first incisor
pathway index formation 894. Similarly, a gap between the second incisor
pathway index
formation punch 996 and the second incisor pathway index formation anvil 997
is
substantially the same as a thickness of the material of the second incisor
pathway index
formation 896. The first incisor pathway index formation punch 994 and the
second incisor
pathway index formation punch 996 are used to maintain alignment between the
strikes of the
progressive stations of the first score line segment punch tool 960B and the
second score line
segment punch tool 960C.
[00546] A first score line segment punch tool 960B is similar to the lid
alignment feature
punch tool 960A. with the introduction of a first score line formation segment
punches 933.
The first score line formation segment punches 933 is divided into two
segments, each
segment extends between a respective first score line formation segment punch
ends ready
for overlap 938 and tear panel hinge formation punch area 939. The resealable
container lid
810 would be seated within a subsequent lid alignment feature anvil 910A in
the
manufacturing process, employing the registration features 993, 997 on the lid
alignment
feature anvil 910A and respective registration features 894, 896 on the
resealable container
lid 810 to ensure accurate alignment. The first score line segment punch tool
960B would
then be employed to create in at least one first score line formation segments
833 as shown in
FIG. 99.
[00547] A second score line segment punch tool 960C is similar to the lid
alignment
feature punch tool 960A, with the introduction of a score line fracture
thinned initiation
region punch 946 extending between two score line segment overlapping region
punches 947.
Each score line segment overlapping region punches 947 is located to align or
overlap with
the respective location of the first score line formation segment punch ends
ready for overlap
938 of the lid alignment feature with lid bottom score line thinned formation
anvil 910B. This
creates one continuous score line 836. The resealable container lid 810 would
remain seated
within the lid bottom score line thinned formation anvil 910B and the second
score line
segment punch tool 960C would be employed to create a score line fracture
thinned initiation
region 846 extending between each score line segment overlapping regions 847
as shown in
96
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
FIG. 100. The first incisor pathway index formation punch 994 and the second
incisor
pathway index formation punch 996 are used to maintain alignment between the
strikes of the
first score line segment punch tool 960B and the second score line segment
punch tool 960C.
[00548] The score line fracture thinned initiation region punch 946 can
include a slight
convex dome, as best shown in a magnified view illustrated in FIG. 105 (noting
the lid
alignment feature punch tool 960 and the lid bottom score line thinned
formation anvil 910B
are separated from the resealable container lid 810 for clarity of the
features). The lid bottom
score line thinned formation region anvil 995 can also include a slight convex
dome, as best
shown in a magnified view illustrated in FIG. 105. These convex domes 946, 995
form
concave depressions within opposite sides of the first incisor pathway index
formation 894,
more specifically forming a score line fracture thinned initiation region 846
on an upper
surface of the first incisor pathway index formation 894 and a lid bottom
score line thinned
formation region 895 on the opposite, lower surface of the first incisor
pathway index
formation 894. The convex domes of the second score line segment punch tool
960C (or the
complete score line segment punch tool 960D) and the lid bottom score line
thinned
formation anvil 910B are provided to direct a flow of the material outward
along a planar
direction of the material (perpendicular to the generally vertical axis of the
press action).
[00549] In a more common embodiment, the cap receiving socket bottom panel
circular
score line 836 and its respective features can be formed using a single strike
punch, such as a
complete score line punch tool 960D working against the lid alignment feature
with lid
bottom score line thinned formation anvil 910B, illustrated in FIG. 104.
[00550] A resealable container lid 1010, shown in FIGS. 106 through 112,
introduces yet
another variant of an opening configuration. The resealable container lid 1010
includes
features that are similar to those of the resealable container lid 810. Like
features of the
resealable container lid 1010 and the resealable container lid 810 are
numbered the same
except preceded by the numeral '10', unless otherwise stated. The resealable
container lid
1010 includes a cap receiving socket bottom panel circular score line 1036
having an initial
fracturing portion 1046 formed within a first incisor pathway refined chamfer
face 1094 at
one end of the incisor pathway channel 1017, best shown in the magnified
section of the
illustration presented in FIG. 109. The initial fracturing portion 1046 can be
created having
an angled trough or recess. The incisor pathway channel 1017 can be fabricated
using a single
punch process, or, preferably, a multi-step forming process. The exemplary
ends of the
97
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
incisor pathway channel 1017 are formed having a chamfered, linear end walls
to enhance
registration functions or the formation of a score line cap receiving socket
bottom panel
circular score line 1036 or at least one score line feature 1046, 1047. The
initial fracturing
portion of the cap receiving socket bottom panel circular score line 1036 is
routed into the
debossed region of the first incisor pathway refined chamfer face 1094
creating an
overlapping region between the cap receiving socket bottom panel circular
score line 1036
and the score line fracture thinned initiation region 1046, identified as a
score line segment
overlapping region 1047. The initial fracturing portion of the cap receiving
socket bottom
panel circular score line 1036 and the associated score line fracture thinned
initiation region
1046 formed on an interior surface of the first incisor pathway refined
chamfer face 1094 on
the resealable container lid 1010. The resealable container lid 1010
introduces a pair of lid
bottom score line hinge creases 1095 are formed on a bottom surface of the
resealable
container lid 1010 proximate the score line fracture thinned initiation region
1046, as shown
in FIG. 107, and preferably arranged flanking each of two vertical edges
thereof. Each of the
pair of lid bottom score line hinge creases 1095 is preferably arranged in a
vertical orientation
or tangential with the arch of the incisor pathway channel 1017.
[00551] In use, the offset projecting incisor 568 (not shown) would travel
along the incisor
pathway channel 1017 approaching the score line fracture thinned initiation
region 1046
within the first incisor pathway refined chamfer face 1094. The offset
projecting incisor 568
then contacts and applies an opening force onto the score line fracture
thinned initiation
region 1046, causing the score line fracture thinned initiation region 1046 to
fracture. The
fracturing of the score line fracture thinned initiation region 1046 reduces
the strength of the
region, enabling a reduced force to fracture the score line segment
overlapping region 1047
and subsequently the cap receiving socket bottom panel circular score line
1036. The lid
bottom score line hinge crease 1095 directs the material about the score line
fracture thinned
initiation region 1046 to fold outward, introducing a clearance for free
passage of the offset
projecting incisor 568 to exit the end of incisor pathway channel 1017 while
continuing a
downward force on the incisor channel to tear panel surface transition 1092 to
further
propagate fracturing of the cap receiving socket bottom panel circular score
line 1036. The
process of separating the cap receiving socket bottom panel tear panel 1038
from the
resealable container lid upper surface reinforcement formation 1018 continues
as previously
described in other variants, with the offset projecting incisor 568 applying a
downward force
to the incisor channel to tear panel surface transition 1092 in conjunction
with various
98
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
vertical applying force generating features engaging with one another, such as
the incisor
deboss panel 566 engaging with the lead in supplemental score fracture
propagation and tear
panel support boss 1097.
[00552] A resealable container lid 1110, shown in FIGS. 113 through 126,
introduces a
variant that retains the resealable container cap 1160 within the cap
receiving socket of the
resealable container lid 1110. The resealable container lid 1110 includes
features that are
similar to those of the resealable container lid 510. Like features of the
resealable container
lid 1110 and the resealable container lid 510 are numbered the same except
preceded by the
numeral '11' unless otherwise stated, wherein the variant of the container lid
510 is adapted
to retain a resealable container cap 1160 and the resealable container lid
1110 as an assembly
throughout the use thereof. The key distinction between the resealable
container lid 1110 and
the resealable container lid 510 is the formation of the cam tracks 1152,
1154, 1156, more
specifically shown reflecting upon the first socket cap retaining cam track
1152 as an
exemplary cam track, a cam track cam follower locking section 1152E, as best
shown in FIG.
126. The cam track cam follower locking section 1152E is routed downward
compared to the
cam track cam follower leader section 552E of FIG. 53, which is routed upward.
The
resealable container cap 1160 includes additional features related to the
primary intention of
this variant, wherein the resealable container lid 1110 and the resealable
container cap 1160
are designed to remain assembled to one another. A resealable container cap
dispensing
aperture 1161 is introduced through a resealable container cap planar
traversing surface 1164
of the resealable container cap 1160. The resealable container cap dispensing
aperture 1161 is
located in rotational alignment with an opening defined by the cap receiving
socket bottom
panel circular score line 1136 of the resealable container lid 1110, as shown
in FIGS. 122 and
123. A tear panel conforming sealing gasket 1165 is carried by an underside of
the resealable
container cap planar traversing surface 1164. The tear panel conforming
sealing gasket 1165
is located in rotational alignment with the opening defined by the cap
receiving socket bottom
panel circular score line 1136 of the resealable container lid 1110, but
offset from the
resealable container cap dispensing aperture 1161, as shown in FIG. 117. The
tear panel
conforming sealing gasket 1165 can be of any suitable shape to adequately seal
the opening
defined by the cap receiving socket bottom panel circular score line 1136 of
the resealable
container lid 1110. In the exemplary embodiment, the tear panel conforming
sealing gasket
1165 is teardrop shaped to accommodate the shape of the dispensing aperture,
more
specifically, the region about the tear panel hinge 1139. The resealable
container cap
99
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
dispensing aperture 1161 enables access and dispensing of contents from within
a breached
resealable container lid 1110 of the resealable container 1100. The tear panel
conforming
sealing gasket 1165 seals the opened container after the cap receiving socket
bottom panel
circular score line 1136 has been fractured and the cap receiving socket
bottom panel tear
panel 1138 has been bent away from the resealable container lid upper surface
reinforcement
formation 1118. The resealable container cap 1160 is retained within a cap
receiving socket
of the resealable container lid 1110 by the shape of the cam tracks. The cam
track assembly /
locking detent 1152A limits the motion of the respective cam follower 1181 in
a clockwise
direction. The modification to the cam track cam follower locking section
1152E limits the
motion of the respective cam follower 1181 in a counterclockwise direction.
The same
rotational limitations are provide by each can track 1152, 1154, 1156 and
respective cam
follower 1181, 1182, 1183. When packaged, the cam follower 1181 is located at
the cam
track initial / resealed section 1152B segment of the first socket cap
retaining cam track 1152.
The remaining cam followers 1182, 1183 would be located at similar segments of
the
respective cam tracks 1154, 1156. This assembly configuration retains the
resealable
container cap 1160 in a fixed rotational position during shipping,
distribution, sale, etc. until
use. In use, the consumer would rotate the resealable container cap 1160 in a
counterclockwise motion causing the offset projecting incisor 1168 to fracture
the cap
receiving socket bottom panel circular score line 1136 in a manner similar to
the offset
projecting incisor 568 fracturing the cap receiving socket bottom panel
circular score line 536
(previously described above). As the resealable container cap 1160 continues
to rotate, the
resealable container cap dispensing aperture 1161 is positioned over the
dispensing aperture
defined by the fractured cap receiving socket bottom panel circular score line
1136, as shown
in FIGS. 123, 124. When the consumer decides they are finished dispensing a
desired volume
of the contents from with the resealable container 1100, the consumer rotates
the resealable
container cap 1160 in a clockwise direction, aligning the tear panel
conforming sealing gasket
1165 over the dispensing aperture defined by the fractured cap receiving
socket bottom panel
circular score line 1136, as shown in FIGS. 124 and 125. Additional
illustrations are included
to adequately present details of the resealable container lid 1110 and the
respective resealable
container cap 1160 as well as the interactions with one another.
[00553] All of the above configurations employ a counterclockwise rotation for
fracturing
the cap receiving socket bottom panel circular score line 536, 736, 836, 1036,
1136 of the
respective resealable container lid 510, 710, 810, 1010, 1110. Each of these
configurations
100
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
are adapted to retain the respective resealable container cap 560, 660. 1160
within the cap
receiving cavity of the respective resealable container lid 510, 710, 810,
1010, 1110 after the
manufacturing process as well as the distribution and sales processes.
[00554] It is understood that the container lid can be modified to use a
reusable or
separately available version of a container cap. A resealable container lid
1210 is adapted to
receive a reusable or separately available version of a container cap, such as
a container lid
socket engaging opening tool 1260, as shown in FIGS. 127 through 135. The
resealable
container lid 1210, detailed in FIGS. 127 through 129, includes features that
are similar to
those of the resealable container lid 510. Like features of the resealable
container lid 1210
and the resealable container lid 510 are numbered the same except preceded by
the numeral
'12'. In this configuration, the resealable container 1200 would be
manufactured, distributed,
and sold excluding the container lid socket engaging opening tool 1260, which
would be a
sealed version of the container shown in FIG. 134. In the resealable container
lid 510. the cap
receiving socket bottom panel circular score line 536 and the other respective
opening
features are oriented to accommodate a counterclockwise rotation of the
resealable container
cap 560 to fracture the cap receiving socket bottom panel circular score line
536 and open the
cap receiving socket bottom panel tear panel 538 thereof. Conversely, in the
resealable
container lid 1210, the cap receiving socket bottom panel clockwise opening
circular score
line 1236 and the other respective opening features are oriented to
accommodate a clockwise
rotation of the container lid socket engaging opening tool 1260 to fracture a
cap receiving
socket bottom panel clockwise opening circular score line 1236 and open a
clockwise
opening tear panel 1238 thereof. Essentially, the cap receiving socket bottom
panel clockwise
opening circular score line 1236 and the other respective opening features are
a mirror image
of the cap receiving socket bottom panel circular score line 536 and the other
respective
opening features.
[00555] The concept no longer requires the features to entrap the offset
projecting incisor
568 within the incisor pathway channel 517 and just prior to the incisor
channel to tear panel
surface transition 592, as the container lid socket engaging opening tool 1260
is no longer
pre-assembled to the resealable container lid 1210. One additional benefit of
this
configuration is that the container lid socket engaging opening tool 1260 can
be axially
symmetric, enabling assembly of the container lid socket engaging opening tool
1260 to the
resealable container lid 1210 in any of three orientations. Although the
exemplary
101
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
embodiment mirrors the features of the container lid socket engaging opening
tool 1260 in
three 120 degree angular sections, it is understood that the resealable
container lid 1210 and
the container lid socket engaging opening tool 1260 can be design having any
suitable
number of like angular sections.
[00556] The container lid socket engaging opening tool 1260, detailed in FIGS.
130
through 133, is a variant of the resealable container cap 560, and includes
features that
function similar to those of the resealable container cap 560. Like features
of the container lid
socket engaging opening tool 1260 and the resealable container cap 560 are
numbered the
same except preceded by the numeral '12', unless otherwise stated. The
container lid socket
engaging opening tool 1260 can be formed using any suitable manufacturing
process. The
exemplary container lid socket engaging opening tool 1260 is fabricated using
a molding
process. The container lid socket engaging opening tool 1260 includes a
opening tool exterior
sidewall 1262 carrying a plurality of like cam followers 1281 extending
radially outward
therefrom, being equidistantly spaced about a lower peripheral edge thereof.
An opening tool
container overlapping sidewall 1271 spatially circumscribes the opening tool
exterior
sidewall 1262 of the container lid socket engaging opening tool 1260 forming
an opening tool
container body and lid assembly seam cavity 1270 therebetween. The opening
tool container
body and lid assembly scam cavity 1270 is sized and shaped to fit over a
container body and
lid assembly seam 1209 of a resealable container 1200. A plurality of gripping
features, such
as a opening tool grip elements 1274 and respective opening tool grip element
force
application surfaces 1275) are formed about the radial, exterior surface of
the opening tool
container overlapping sidewall 1271. A plurality of opening tool dispensing
aperture 1261 is
formed through the opening tool planar traversing surface 1264. Each opening
tool
dispensing aperture 1261 would be located to rotate into a position enabling
dispensing of
contents from within the resealable container 1200.
[00557] A plurality of incisors 1268 extend axially downward from a sealing
surface of the
opening tool planar traversing surface 1264, the incisors 1268 being
equidistantly spaced and
equidistant from a rotational axis of the container lid socket engaging
opening tool 1260. Any
of the incisors 1268 can be used for initiating a fracture of the cap
receiving socket bottom
panel clockwise opening circular score line 1236.
[00558] In use, the container lid socket engaging opening tool 1260 would be
assembled
onto the resealable container lid 1210 by aligning each opening tool formed
cam follower
102
CA 03015350 2018-08-20
WO 2017/151419 PCT/US2017/019274
1281 with each inter-cam relief section 1251, 1253. 1255 and slipping each
opening tool
formed cam follower 1281 beneath each cam track 1252, 1254, 1256, more
specifically,
engaging with the upward angled end, similar to the cam track cam follower
leader section
552E previously described. The upward angled end of the respective cam track
1252, 1254,
1256 guide the respective opening tool formed cam follower 1281 into the
generally
horizontally arranged segment of the cam track 1252. 1254, 1256, similar to
the cam track
operating segment 552D. The consumer would continue to rotation the container
lid socket
engaging opening tool 1260 in a clockwise motion to fracture the cap receiving
socket bottom
panel clockwise opening circular score line 1236 at the incisor channel to
tear panel surface
transition 1292 and subsequently propagate the fracture of a cap receiving
socket bottom
panel clockwise opening circular score line 1236, while folding or bending a
clockwise
opening tear panel 1238 away from a resealable container lid upper surface
reinforcement
formation 1218 along a clockwise opening tear panel hinge 1239, as shown in
FIG. 135.
Once the complete cap receiving socket bottom panel clockwise opening circular
score line
1236 is fractured and the clockwise opening tear panel 1238 is folded away
from the
resealable container lid upper surface reinforcement formation 1218, the
container lid socket
engaging opening tool 1260 is rotated into a position aligning one opening
tool dispensing
aperture 1261 with the dispensing aperture created by the fractured cap
receiving socket
bottom panel clockwise opening circular score line 1236. The clockwise
rotation of the
container lid socket engaging opening tool 1260 is limited by a downward turn
of each
respective cam track 1252, 1254, 1256, similar to the cam track assembly /
locking detent
segment 552A previously introduced. The container lid socket engaging opening
tool 1260 is
removed by rotating the container lid socket engaging opening tool 1260 in a
counterclockwise direction until each opening tool formed cam followers 1281
is placed into
the respective inter-cam relief section 1251, 1253, 1255. Once each opening
tool formed cam
followers 1281 is placed into the respective inter-cam relief section 1251,
1253, 1255, the
container lid socket engaging opening tool 1260 can be lifted from the cap
receiving socket
of the resealable container lid 1210. It is noted that the exemplary cap 1260
does not include
features enabling resealing of the compromised or opened resealable container
lid 1210. The
container lid socket engaging opening tool 1260 can be modified to include a
sealing feature.
Alternatively, other caps can be employed to seal the compromised or opened
resealable
container lid 1210. In yet another configuration, the container lid socket
engaging opening
tool 1260 can be exclusive of the opening tool dispensing aperture 1261,
simply providing an
opening function.

CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
[00559] Previous variants include a seal between the cap sealing ring 565,
located on a
bottom surface of the resealable container cap planar traversing wall 564 of
the resealable
container cap 560 and a cap receiving socket bottom wall 534 of the resealable
container lid
510. In another variant, the seal can be provided between features of the
vertical sidewall of
the resealable container cap 560 and the resealable container lid 510. This
variant is
employed between a resealable container lid 1310 and a resealable container
cap 1360, which
are described in FIGS. 136 through 146.
[00560] The resealable container lid 1310, detailed in FIGS. 136 and 137, is a
variant of
the resealable container lid 510, and includes features that function similar
to those of the
resealable container lid 510. Like features of the resealable container lid
1310 and the
resealable container lid 510 are numbered the same except preceded by the
numeral '13'. The
resealable container cap 1360, detailed in FIGS. 138 and 139, is a variant of
the resealable
container cap 560, and includes features that function similar to those of the
resealable
container cap 560. Like features of the resealable container cap 1360 and the
resealable
container cap 560 are numbered the same except preceded by the numeral '13'.
[00561] The resealable container lid 1310 includes a frustum shaped interior
surface of a
frustum shaped cap seal engaging annular surface 1340, as best shown in a
section view
illustrated in FIG. 143. The frustum shaped cap seal engaging annular surface
1340 extends
axially between a cap receiving socket cylindrical sidewall 1332 and a seaming
chuck
shoulder 1324 of the rescalable container lid 1310. The frustum shaped cap
seal engaging
annular surface 1340 is located between the functional cam region of the
resealable container
lid 1310 and the seaming panel elements, including the seaming chuck wall 1322
and the
seaming panel 1320.
[00562] The reseal able container cap 1360 includes a frustum shaped exterior
surface of a
frustum shaped cap sealing ring surface 1367, as best shown in a section view
illustrated in
FIG. 143. The frustum shaped cap sealing ring surface 1367 extends axially
between a
resealable container cap cylindrical exterior sidewall 1362 and a cylindrical
sidewall inverted
countersink 1370 of the frustum shaped cap sealing ring surface 1367. The
frustum shaped
cap sealing ring surface 1367 is located between the region containing the
functional cam
followers 1381, 1382, 1383 of the resealable container cap 1360 and the
cylindrical side wall
inverted countersink 1370. A frustum shaped cap sealing ring 1365 is applied
to the exterior
surface of the frustum shaped cap sealing ring surface 1367. The frustum
shaped cap sealing
104
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
ring 1365 can be of any suitable material, such as those previously suggested
for the cap
sealing ring 565.
[00563] When the resealable container cap 1360 and the resealable container
lid 1310 are
assembled to one another, the frustum shaped cap sealing ring 1365 seals
against the interior
surface of the frustum shaped cap seal engaging annular surface 1340, as best
shown in FIGS.
144, 146. The spatially arranged cam followers 1381, 1382, 1383, interacting
with the
respective cam track 1352, 1354, 1356 generally evenly distribute a
compression load
between the frustum shaped cap sealing ring surface 1367 and the frustum
shaped cap seal
engaging annular surface 1340.
[00564] In the resealable container cap 1360, a concentric tamper indicator
operation
element 1329 on a concentric tamper indicator feature 1328 is centrally
located. The
concentric tamper indicator operation element 1329 is supported by an upper
surface of the
resealable container lid upper surface reinforcement formation 1318. The
resealable container
lid upper surface reinforcement formation 1318 is supported by the pressure
within the sealed
interior of the container. Once the seal is compromised, the pressure is
released, thus
eliminating any support to and from the resealable container lid upper surface
reinforcement
formation 1318. Without the support, the resealable container lid upper
surface reinforcement
formation 1318 can flex axially, thus allowing the concentric tamper indicator
feature 1328 to
flex accordingly and report the breach of the container.
[00565] In yet another embodiment, a resealable container lid 1410 and a
respective
resealable container cap 1460 are adapted to support a solid composition (i.e.
food) storage
and distribution container, wherein the resealable container lid 1410 is
described in FIGS.
147 through 158.
[00566] It is understood that the resealable container lid 1410 can be used
for smaller and
larger food products, such as those mentioned above an additionally including
chips, pretzels,
potato sticks, larger nuts, larger spices, candies, span, thicker soups,
spreadables, peanut
butter, jelly, larger condiments (sauerkraut, relish), and the like.
[00567] The resealable container lid 1410, detailed in FIGS. 147 and 148,
is a variant of
the resealable container lid 510, and includes features that function similar
to those of the
resealable container lid 510. Like features of the resealable container lid
1410 and the
resealable container lid 510 are numbered the same except preceded by the
numeral '14'. The
105
CA 03015350 2018-08-20
WO 2017/151419 PCT/1JS2017/019274
resealable container cap 1460, detailed in FIGS. 149 and 150, is a variant of
the resealable
container cap 560, and includes features that function similar to those of the
resealable
container cap 560. Like features of the resealable container cap 1460 and the
resealable
container cap 560 are numbered the same except preceded by the numeral '14'.
[00568] The resealable container lid 1410 is provided with a removable sealed
panel (not
shown) spanning across a lower end thereof, or as a ring shaped element having
a container
lid dispensing aperture 1461. In a configuration where the resealable
container lid 1410
includes a removable sealed panel spanning across a lower end thereof, the
peripheral edge of
the sealing panel can be defined by a score line. The removable seal can be
opened and
removed using any suitable element, such as a pull tab. The removable panel
may also be of a
plastic or metal foil material bonded to the lower end of the resealable
container lid 1410. In a
configuration excluding the removable seal bottom panel, a lower edge of the
resealable
container cap cylindrical exterior sidewall 1462 can be formed, introducing a
peripheral
bottom edge fold 1426 as a fold to reinforce the lower edge of the resealable
container cap
cylindrical exterior sidewall 1462 of the resealable container lid 1410 and to
minimize any
risk of injury.
[00569] The resealable container lid 1410 is assembled to the container
cylindrical
sidewall 102 using the same methods previously described. The exclusion of the
cap
receiving socket bottom wall 534 in the resealable container lid 1410 suggests
modifications
to the pneumatically operated concentric tamper indicator feature 1428. The
pneumatically
operated concentric tamper indicator feature 1428 excludes a tamper indicator
operation
element, as the resealable container lid 1410 excludes a cap receiving socket
bottom wall,
rendering the tamper indicator operation element as being of no use. The
pneumatically
operated concentric tamper indicator feature 1428 obtains support directly
from pressure
differential within the sealed contents section of the container.
[00570] The container lid cap can include a grip of any suitable
configuration. The
previous container lid caps 160, 260, 360, 460, 560, 660, 1160, 1360, 1460,
each included a
grip formation extending upward from a resealable container cap base element
or planar
traversing wall 564, 664, 1164, 1364, 1464. The container lid socket engaging
opening tool
1260 includes a grip element formed on a radially exterior surface of the
opening tool
container overlapping sidewall 1271. A resealable container cap 1560, detailed
in FIGS. 159
and 160, introduces a debossed grip configuration resealable container cap
grip element
106
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
cavity 1574 extending inward into an interior region of the resealable
container cap 1560.
The resealable container cap 1560 includes features having similar function to
those of the
resealable container cap 1360. Like features of the resealable container cap
1560 and the
resealable container cap 1360 are numbered the same except preceded by the
numeral '15',
unless otherwise stated. Since the sealing features (frustum shaped cap
sealing ring 1565
carried by a frustum shaped cap sealing ring surface 1567) are employed to
provide a seal, a
lower surface of the resealable container cap planar traversing surface 1564
is no longer
mandated to contact the cap receiving socket bottom wall 1334, thus
eliminating design
constraints imposed by the cap sealing ring 565 of the resealable container
cap 560. This
enables the resealable container cap planar traversing surface 1564 to extend
radially inward
from an upper edge of the resealable container cap cylindrical lower exterior
sidewall 1562.
The resealable container cap 1560 can include a resealable container cap
cylindrical upper
exterior sidewall 1563, providing a transition between an upper edge of the
resealable
container cap cylindrical lower exterior sidewall 1562 and the outer edge of
the resealable
container cap planar traversing surface 1564. The height of the resealable
container cap 1560
would preferably be designed to retain an uppermost surface thereof at or
below an
uppermost edge of the seaming panel 1320, as best shown in FIG. 165. The
resealable
container cap cylindrical upper exterior sidewall 1563 and resealable
container cap planar
traversing surface 1564 are preferably designed to nest within the cavity of
the seaming
chuck tool cap clearance cavity 603 on the seaming chuck tool 600 during the
seaming
process of the resealable container lid 1310 to the container body.
[00571] Since the resealable container cap planar traversing surface 1564
extends across a
highest region of the resealable container cap 1560, the resealable container
cap grip element
cavity 1574 can be formed as a deboss, extending inward from the top surface
of the
resealable container cap planar traversing surface 1564. The resealable
container cap grip
element cavity 1574 includes a cap grip element cavity force application
surface 1575,
functioning the same as the cap grip element force application surface 575
(previously
described), while being a tubular interior surface thereof. An upper
transition between the cap
grip element cavity force application surface 1575 and the resealable
container cap planar
traversing surface 1564 is chamfered, creating a comfort region for the
consumer during the
opening and resealing processes. A depth of the resealable container cap grip
element cavity
1574 would place a bottom surface of the resealable container cap grip element
cavity 1574
at a desired vertical position respective to an assembly reference feature,
such as the cam
107
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
followers 1581, 1582, 1583, a bottom edge of the resealable container cap
cylindrical lower
exterior sidewall 1562, and the like. This locates a bottom surface of a cap
grip bottom wall
incisor deboss panel 1566 and a depth of a respective cap grip bottom wall
projecting incisor
1568 adequately to properly interact with the opening features of the
resealable container lid
1310 or other respective container lid, as best shown in FIGS. 165, 167.
Assembly of the
resealable container cap 1560 to the resealable container lid 1310 would be
the same as
previously described. The significant difference is the consumer would insert
their fingers
and/or a tool into the resealable container cap grip element cavity 1574,
resting against the
cap grip element cavity force application surface 1575 to apply a torsional
force thereto.
Obviously, the resealable container cap grip element cavity 1574 would be
designed to
accommodate the consumer's fingers and/or an opening assistance tool.
[00572] Continuing with variations in grip designs, a resealable container cap
1660,
detailed in FIGS. 168 and 169, introduces another embossed grip configuration
resealable
container cap grip element 1674 extending upward from the resealable container
cap planar
traversing surface 1664 of the resealable container cap 1660. The resealable
container cap
1660 includes features having similar function to those of the resealable
container cap 560.
Like features of the resealable container cap 1660 and the resealable
container cap 560 are
numbered the same except preceded by the numeral '16'.
[00573] The resealable container cap 560 includes a resealable container cap
grip element
574 having a pinched shape to define the cap grip element force application
surfaces 575. The
resealable container cap grip element 1674 is formed having a more cylindrical
shaped cap
grip element force application surface 1675 terminating with a cap grip
element grip
enhancing feature 1676 circumscribing a distal edge of the cap grip element
force application
surface 1675 or a peripheral edge of a top panel thereof. It is recognized
that the cap grip
element force application surface 1675 and cap grip element grip enhancing
feature 1676 as
well as the entire resealable container cap grip element 1674 can be of any
suitable shape.
The preferred shape of the cap grip element force application surface 1675 is
cylindrical for
manufacturing and reliability purposes. The off-center tamper indicator
feature 1628 can be
located off-centered (as shown) or concentric with a resealable container cap
cylindrical
interior sidewall 1663 of the resealable container cap 1660. The resealable
container cap 1660
would be assembled into any suitable container lid, such as the exemplary
resealable
container lid 510 shown in FIG. 170. It is noted that the resealable container
cap grip element
108
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
1674 is of a height where an upper surface of each resealable container cap
grip element 1674
is at or lower than a respective surface of the seaming panel 520 when the
resealable
container cap 1660 is assembled within a cap receiving socket of the
resealable container lid
510.
[00574] The consumer can use their fingers to apply an opening force directly
to each cap
grip element force application surface 1675 of each resealable container cap
grip element
1674. Alternatively, the consumer can employ a resealable container cap
opening assistance
tool 1760, introduced in FIGS. 171 through 173, to aid in rotating the
resealable container cap
1660 to fracture the cap receiving socket bottom panel circular score line 536
of the
resealable container lid 510, separating and folding the cap receiving socket
bottom panel tear
panel 538 away from the resealable container lid upper surface reinforcement
formation 518.
[00575] The resealable container cap opening assistance tool 1760 is
preferably fabricated
of a pliant material using a molding process. The resealable container cap
opening assistance
tool 1760 includes a opening assistance tool upper cylindrical sidewall 1761
having a
plurality of spatially arranged gripping sections (comprising opening
assistance tool grip
elements 1784, each opening assistance tool grip element 1784 extending
outward from a
peripheral surface of the opening assistance tool upper cylindrical sidewall
1761 by a pair of
opening assistance tool force application surfaces 1785. An opening assistance
tool lower
cylindrical sidewall 1763 extends downward from a bottom surface of the
opening assistance
tool upper cylindrical sidewall 1761. The opening assistance tool lower
cylindrical sidewall
1763 is sized and shaped to fit within the cap receiving cavity of the
resealable container lid
510, more specifically to fit within the cavity defined by the resealable
container cap
cylindrical interior sidewall 1663, as best shown in FIGS. 174, 176. The
peripheral edge of
the opening assistance tool upper cylindrical sidewall 1761 is sized to extend
outward from a
peripheral edge of the container to avoid any interference of the features of
the container and
associated container lid resealable container cap 560 during use of the
resealable container
cap opening assistance tool 1760. At least one opening assistance tool cap
grip receiving
cavity 1774 is formed as a cavity extending inward from an opening assistance
tool bottom
wall 1764 of the opening assistance tool lower cylindrical sidewall 1763. Each
of the at least
one opening assistance tool cap grip receiving cavity 1774 includes a opening
assistance tool
grip enhancing feature 1776 circumscribing an interior edge of a respective
opening
assistance tool force application surface 1775. The opening assistance tool
force application
109
CA 03015350 2018-08-20
WO 2017/151419 PCMJS2017/019274
surface 1775 and associated opening assistance tool grip enhancing feature
1776 are of a size
and shape to compliment the respective resealable container cap grip element
1674, more
specifically, the cap grip element force application surface 1675 and the cap
grip element grip
enhancing feature 1676 of the resealable container cap grip element 1674, as
best shown in
FIGS. 174, 176. The quantity and location of each of the at least one opening
assistance tool
cap grip receiving cavity 1774 are determined by the quantity and location of
each of the at
least one resealable container cap grip element 1674. The pliant material of
the resealable
container cap opening assistance tool 1760 enables the opening assistance tool
cap grip
receiving cavity 1774 to deform during an assembly step, compensating and
allowing the
enlarged cap grip element grip enhancing feature 1676 to pass through the
slightly narrowed
opening assistance tool force application surface 1775 of the opening
assistance tool cap grip
receiving cavity 1774, until the cap grip element grip enhancing feature 1676
is seated into
the opening assistance tool grip enhancing feature 1776. Once the resealable
container cap
opening assistance tool 1760 is properly seated and engaging the resealable
container cap
1660, the user grasps the grips 1784, 1785 and applies a rotational force
thereto. The enlarged
peripheral edge of the opening assistance tool upper cylindrical sidcwall
1761, in conjunction
with the pliant material aids the user in rotating the resealable container
cap 1660 within the
resealable container lid 510 during use. The engagement between the opening
assistance tool
grip enhancing feature 1776 and the cap grip element grip enhancing feature
1676 enables the
user to remove the resealable container cap 1660 from the cap receiving socket
of the
resealable container lid 510 by simply lifting the resealable container cap
opening assistance
tool 1760 away from the resealable container lid 510. The engagement between
the opening
assistance tool grip enhancing feature 1776 and the cap grip element grip
enhancing feature
1676 retains the assembly of the resealable container cap 1660 to the
resealable container cap
opening assistance tool 1760.
[00576] It is understood the resealable container cap opening assistance tool
1760 can be
fabricated of a more rigid, molded material. When manufactured using the more
rigid
material, the opening assistance tool force application surface 1775 would be
the same shape
and size as the opening assistance tool grip enhancing feature 1776, enabling
insertion of
each resealable container cap grip element 1674 into the respective opening
assistance tool
cap grip receiving cavity 1774.

WO 2017/151419 PCMJS2017/019274
[00577] It is understood that the opening assistance tool cap grip receiving
cavities 1774 of
the resealable container cap opening assistance tool 1760 can be incorporated
into any of the
other cavity shaped container lid caps 160, 260, 360, 460, 560, 660, 1160,
1360. 1460.
[00578] The container lid caps 560, 660, 1160, 1260, 1360, 1460 can be
replaced by other
container lid caps having more specialized features and related functions, as
shown in the
various configurations presented in FIGS. 177 through 186. These specialized
caps can be
included with the container, sold separately, or both. The specialized caps
give the consumer
the ability to adapt any container into a specialized application.
[00579] A first exemplary specialized cap is a drinking straw socket accessory
1800,
detailed in FIGS. 177 through 181. The drinking straw socket accessory 1800
introduces a
mason jar-like cap assembly design. The assembly design employs two elements,
a stationary
/ axially operable component 1810, which remains in a fixed rotational
position, and a socket
mating rotary actuator 1860, which rotates, assembling the drinking straw
socket accessory
1800 to a respective container lid, such as the resealable container lid 510
or any other
suitable container lid. The exemplary stationary / axially operable component
1810 includes a
cylindrical vertical wall circumscribing a peripheral edge of a socket
accessory traversing
wall 1834. In an alternative version, the cylindrical vertical wall 1832 can
extend downward
from a bottom surface of the socket accessory traversing wall 1834. A socket
mating rotary
actuator helical groove track cam follower 1880 is incorporated into the
exterior surface of
the cylindrical vertical wall 1832 of the stationary / axially operable
component 1810. A
socket accessory sealing ring 1865 is carried about a bottom edge of the
cylindrical vertical
wall 1832. A socket accessory off-center tear panel plug 1838 extends downward
from an
underside of the socket accessory traversing wall 1834. The socket accessory
off-center tear
panel plug 1838 is adapted to engage with the dispensing aperture formed
within the
resealable container lid upper surface reinforcement formation 518 when the
cap receiving
socket bottom panel tear panel 538 is folded into an opened configuration. The
socket
accessory off-center tear panel plug 1838 would preferably be shaped and sized
to
substantially or completely seal the dispensing aperture formed within the
resealable
container lid upper surface reinforcement formation 518. This would avoid
leakage of the
contained beverage to an area between the socket accessory off-center tear
panel plug 1838
and the socket accessory sealing ring 1865.
