Detailed Description of Preferred Embodiments
FIG. 1 illustrates a package 20 including a container 22, and a closure 24
that is
coupled to the container 22. The package 20 may be used to package pickles,
baby food, salsa,
peppers, spaghetti sauces, jams, or any other food products. The package 20
also may be used
to package other types of products including but not limited to liquids, gels,
powders, particles,
and the like.
The container 22 may be composed of glass, or any other material suitable for
containing fiood products. The container 22 may be provided in any suitable
sizes, and may be a
wide mouth type of container. The container 22 includes a body 26 including a
base 28, and a
sidewall 30 extending in a direction axially away from the base 28. The body
26 also may
include a shoulder 32 extending from the sidewall 30, as illustrated in the
Figures. In other
embodiments, however, the container body 26 need not include a shoulder. As
used herein,
directional words such as top, bottom, upper, lower, radial, circumferential,
lateral, longitudinal,
transverse, vertical, horizontal, and the like are employed by way of
description and not
limitation.
Referring to FIGS. 2 through 4, the container 22 also has a first,
longitudinal axis
A, and includes a neck finish 34 extending from the body 26. More
particularly, the neck finish
34 may extend from the shoulder 32 of the sidewall 30. In other embodiments,
however, where
5
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
the container body 26 does not include a shoulder, the neck finish 34 may
extend directly from
the sidewall 30. The neck finish 34 includes a lower portion 36 and an upper
portion 38 remote
from the body 26 and extending from the lower portion 36. The lower portion 36
may be
cylindrical, and the upper portion 38 may be non-cylindrical.
The lower portion 36 may extend completely circumferentially around the neck
finish 34, and has an outer surface 40 and one or more closure engagement
features that may
include lugs, bayonets, thread segments 42, or any other suitable features, on
the outer surface
40. As used herein, the term thread segment includes whole, partial, multiple,
and/or an
interrupted thread and/or thread segment. The thread segments 42 may include
two, three, four,
or any suitable quantity of thread segments 42. In any case, the thread
segments 42 may extend
completely circumferentially around the neck finish 34. The lower portion 36
also may include
a capping flange 44 extending completely circumferentially around the neck
finish 34 and
disposed axially between the thread segments 42 and the body shoulder 32.
The upper portion 38 includes indents or spout walls 46 disposed radially
inwardly with respect to the lower portion 36 and laterally opposed from one
another on either
side of a second, radial axis B (FIG. 5). The upper portion 38 also may
include shoulders or
ledges 48 disposed between the spout walls 46 and the outer surface 40 of the
lower portion 36,
As used herein the term "ledge" generally includes a portion extending
transversely to the axis A
and adjacent to the higher, more prominent, spout walls 46.
The upper portion 38 also may include a rear wall 50 extending between the
spout
walls 46 at rear ends of the spout walls 46. The rear wall 50 may be semi-
circular or
6
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
semi-cylindrical in shape and may be an extension of a corresponding portion
of the lower
portion 36 of the neck finish 34.
The upper portion 38 further may include a trough wall 52 extending
circumferentially between the spout walls 46 at forward ends of the spout
walls 46, and disposed
on an opposite side of a third, transverse radial axis C from the rear wall
50. The trough wall 52
also may be semi-circular or semi-cylindrical in shape and may extend axially
from a
corresponding part of the lower portion 36 of the neck finish 34. The trough
wall 52 may
include a lip or projection 51 and a recessed portion 53, for example, to aid
in pouring contents
from the container 22 in a clean or anti-drip manner. The projection 51 may
extend from the
sealing surface 54 in an axial direction toward the thread segments 42. The
recessed portion 53
may be disposed axially between the projection 51 and the thread segment(s)
42, and the recessed
portion 53 may disposed radially inward of a radially outermost portion of the
projection 51.
For example, a radially outer surface of the projection 51 may have the same
radial dimension as
a corresponding radially outer surface of the rear wall 50, whereas a radially
outer surface of the
recessed portion 53 may have a radial dimension that is smaller than the
radially outer surfaces of
the projection 51 and/or the rear wall 50.
In other embodiments, the rear and trough walls 50, 52 may be of any other
suitable shapes. Also, the spout walls 46 alone or together with other
portions of the container
22 (e.g. the trough wall 52) may form a pour spout 47.
The walls 46, 50, 52 of the upper portion 38 of the neck finish 34 may
terminate
in a planar sealing surface 54. At least for the reason that the spout walls
46 may be disposed
radially inwardly of the rear wall 50, the planar sealing surface 54 may be
non-circular. In
7
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
particular, the spout walls 46 may be incurvate with respect to the first axis
A. Also, the upper
portion 38 may be clamshell-shaped when viewed from above the upper portion 38
along the axis
A.
One or more of the thread segments 42 may be disposed in a circumferential
overlapping relationship with the spout walls 46, the rear wall 50, and the
trough wall 52.
Accordingly, the securement of the closure 24 may be symmetrical, and
uninterrupted or
continuous, around the container 22.
Referring to FIG. 6, the container 22 may include an interior 56, a sidewall
interior surface 58 of the body sidewall 30, a shoulder interior surface 60 of
the body shoulder
32, a rear wall interior surface 62 of the neck finish 34 at a location
corresponding to the rear
wall 50, and a trough wall interior surface 64 of the neck finish 34 at a
location corresponding to
the trough wall 52. As shown in FIG. 6, an inside diameter between the rear
and trough walls
50, 52, or an inside radius of the interior surface 62 of the neck finish 34,
may be greatest at the
sealing surface 54 and may be smallest at the lower portion 36 (FIG. 4). Also
as shown in FIG.
6, the radial wall thickness of the neck finish 34 at locations corresponding
to the rear and trough
walls 50,52 may be the same and may be symmetrical.
Referring to FIGS. 7-10, the container 22 also may include thickened wall
portions 66. The thickened wall portions 66 may correspond with the spout
walls 46 and may
be circumferentially spaced apart. Also, the thickened wall portions 66 may
form an internal
trough to direct flow of product toward the pour spout between the spout walls
46. The
thickened wall portions 66 may be disposed beneath the spout walls 46 or
axially between the
spout walls 46 and the base 28 of the container 22. Also, the thickened wall
portions 66 may be
8
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
circumferentially aligned with the spout walls 46. The thickened wall portions
66 may extend
from the neck finish 34 to the shoulder 32, and may also extend to the
sidewall 30.
The container 22 also includes interior surfaces 68 of the container neck
finish
34 at locations corresponding to the spout walls 46. The thickened wall
portions 66 may
include those interior surfaces 68. In addition, the thickened wall portions
66 may form interior
surfaces 58' of a thickened body sidewall portion 30' that are disposed
radially inward of the
interior surfaces 58 of the sidewall 30. The thickened wall portions 66 also
may form interior
surfaces 60' of a thickened body shoulder portion 32' that are disposed
radially inward of the
interior surfaces 60 of the shoulder 32. In any case, the thickened wall
portions 66 extend
radially inwardly, for example toward the axis A with respect to one or more
of the interior
surfaces 58, 60, 62, 64, to form an internal trough to direct flow of product
toward the pour
spout.
FIGS. 11 through 13 illustrate another illustrative embodiment of a container
122.
This embodiment is similar in many respects to the embodiments of FIGS. 1-10
and like
numerals between the embodiments generally designate like or corresponding
elements
throughout the several views of the drawing figures. Accordingly, the
descriptions of the
embodiments are incorporated into one another. Additionally, the description
of the common
subject matter generally may not be repeated here.
The container 122 includes a body 126 including a base 128, a sidewall 130
extending in a direction axially away from the base 128, and a shoulder 132.
The container 122
also has a first, longitudinal axis A, and includes a neck finish 134
extending from the shoulder
132 of the body 126. The neck finish 134 may be the same as that described
above with respect
9
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
to FIGS. 1-10 and, thus, may include a pour spout 147 and may accept the
closure 24 illustrated
in FIG.!.
The sidewall 130 includes a spout indicator 149 circumferentially
corresponding
to the pour spout 147, for instance, to indicate to a user the location of the
pour spout 147 when a
closure (not shown) applied to the container 122 obscures the circumferential
orientation of the
pour spout 147. Accordingly, when using the container 122, a user first may
see the spout
indicator 149 and then grip the container 122 in a suitable location and
manner to enable the user
to remove the closure and pour contents from the container 122 without having
to adjust the
user=s grip to reorient the pour spout 147. The spout indicator 149 may be
circumferentially
aligned with the pour spout 147.
The spout indicator 149 may be provided in any suitable manner. For example,
the spout indicator 149 may be formed from the same material as the rest of
the sidewall 130.
More specifically, the spout indicator 149 and the rest of the sidewall 130
may be formed of glass
in a glass container manufacturing process. In other examples, the spout
indicator 149 may be a
separate component separately applied to the sidewall 130.
Referring to FIG. 13, the sidewall 130 may include a grip 155, for instance,
to
facilitate a good grip of the container 122 and further visually distinguish
the spout indicator 149
so as to further enhance a users ability to quickly spot the spout indicator
149 and begin using
the container 122. The grip 155 may extend circumferentially partially around
the body 126,
may he indented or radially recessed, and may have circumferential ends 155a,
155b that may
defme or establish corresponding circumferential portions 149a, 149b of the
spout indicator 149.
The circumferential ends 155a, 155b of the grip 155 may be excurvate in a
circumferential
CA 02911091 2015-10-30
WO 2014/179006 PCT1US2014/033483
direction and the corresponding ends 149a, 149b of the indicator 149 may be
incurvate in a
circumferential direction, or vice-versa, or the ends may be straight or of
any other suitable
shape.
In the embodiment of FIGS. 11-13, the sidewall 130 may include a first portion
129 extending axially from the base 128 and a second portion 131 extending
axially between the
first portion 129 and the neck finish 134, wherein the second portion 131 may
include the spout
indicator 149 and the pip 155. The shoulder 132 may extend between the grip
155 and the
neck finish 134. Also, the first portion 129 may have a cylindrical outer
surface that may be
recessed as shown, for instance, to accept a product label, whereas the second
portion 131 may
have an outer surface that is incurvate in a radial direction, for instance
for good gripping by a
user.
FIGS. 14 through 17 illustrate another illustrative embodiment of a container
222.
This embodiment is similar in many respects to the embodiments of FIGS. 1-13
and like
numerals between the embodiments generally designate like or corresponding
elements
throughout the several views of the thawing figures. Accordingly, the
descriptions of the
embodiments are incorporated into one another. Additionally, the description
of the common
subject matter generally may not be repeated here.
With reference to FIGS. 14 and 15, the container 222 includes a body 226
including a base 228, a sidewall 230 extending from the base 228, and a
shoulder 232 extending
from the sidewall 230, as illustrated in the Figures. The container 222 also
may include a neck
finish 234 extending from the shoulder 232 of the sidewall 230 of the body
226.
11
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
The sidewall 230 may include a spout indicator 249 circumferentially
corresponding to the pour spout 247. For example, as best shown in FIG. 15,
the spout
indicator 249 may be circumferentially aligned with the pour spout 247. Also,
the spout
indicator 249 may be provided on the shoulder 232. The spout indicator 249 may
be generally
triangular, for instance, with radiused vertices, as illustrated. The spout
indicator 249 may be of
the same smooth surface finish as the rest of the body 226 or, as shown, may
be textured to
provide a surface finish that is coarser than rest of the body 226.
The sidewall 230 also may include a circumferentially extending grip 255. The
grip 255 may extend continuously, circumferentially, entirely around the
container 222 and may
be radially recessed. The grip 255 may be of the same smooth surface finish as
the rest of the
body 226 or, as shown, may be textured to provide a surface finish that is
coarser than rest of the
body 226. The grip 255 may be a relatively narrow band, for example, having a
width or height
less than one-quarter of the height of the body 226. In a more particular
example, the height of
the grip 255 may be less than one-inch.
As shown in FIGS. 14 and 15, the grip 255 may be bordered by transitions
between the outer surface of the sidewall 230 and the grip 255. The shape of
the transitions
may correspond to the shape of the grip 255 itself. The texture of the
transitions may be the
same as that of the sidewall 230 in general.
With reference also to FIGS. 16 and 17, the container 222 also may include
thickened wall portions 266. The thickened wall portions 266 may correspond
with spout walls
246 and may be circumferentially spaced apart to form an internal trough to
direct flow of
product toward the pour spout 247 between spout walls 246. The thickened wall
portions 266
12
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
are similar to those described and shown in the previous embodiments, however,
they may
extend from the spout walls 246 into the neck finish 234 but do not extend
below the shoulder
232 down along the sidewall 230 of the body 226. Otherwise, the thickened wall
portions 266
may be identical to the previously described thickened wall portions 266.
FIGS. 18 through 21 illustrate another illustrative embodiment of a container
322.
This embodiment is similar in many respects to the embodiments of FIGS. 1-17
and like
numerals between the embodiments generally designate like or corresponding

326. The sidewall
.. 330 may include the spout indicator 249 described above with respect to
FIGS. 14-17.
Also, the sidewall 330 may include a grip, which may include multiple grip
portions, for example, two discrete or individual grip portions 355a, 355b.
The grip portions
355a, 355b may be disposed on opposite sides of the container body 326, for
instance,
diametrically opposed from one another on either side of radial axis B as best
shown in FIGS. 19
and 20. The grip portions 355a, 355b may be of the same smooth surface finish
as the rest of
the body 326 or, as shown, may be textured to provide a surface finish that is
coarser than rest of
the body 326. The grip portions 355a, 355b may be generally oval-shaped, for
instance,
13
egg-shaped, ellipse-shaped, oblong, or the like, and/or may correspond to an
index finger
placement and a thumb placement. The grip portions 355a, 355b may be bordered
by
transitions 357a, 357b between the outer surface of the sidewall 330 and the
grip portions 355a,
355b. The shape of the transitions 357a, 357b may correspond to the shape of
the grip portions
355a, 355b. The texture of the transitions 357a, 35Th may be the same as that
of the sidewall
330 in general.
The sidewall 330 may have an outer surface portion 329 that may be recessed as
shown, for instance, to accept a product label. The grip portions 355a, 355b

finish 434. Accordingly, portions of the non-cylindrical interior of the neck
finish 434 may
themselves be circular or cylindrical. But as will be described below, other
portions of the
interior of the neck finish 434 render the neck finish interior generally non-
cylindrical.
For example, the non-cylindrical interior of the container neck finish 434
also may
include spout walls 446 (or thickened wall portions 466 per FIG. 26) disposed
radially inwardly
with respect to the sealing lip 454 and with respect to the rear and trough
walls 450, 452 and
laterally opposed from one another on either side of the trough wall 452,
distal with respect to the
rear wall 450. The trough wall 452 may be disposed between forward ends of the
thickened
wall portions 446 and the rear wall 450 may be disposed between rearward ends
of the thickened
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
wall portions 446. The spout walls 446 alone or together with the trough wall
452 may form a
pour spout 447. The spout walls 446 may be indents, embossments, or thickened
wall portions
466 (e.g, FIG. 26). The spout walls 446 may extend chordally and may be
generally straight as
shown but, in other embodiments, the walls 446 may be incurvate, excurvate, or
of any other
suitable shape. In any case, the spout walls 446 have a radial wall thickness
greater than that of
the rear and trough walls 450, 452.
The spout walls 446 may include shoulders 448 disposed between the
longitudinal
central axis A of the container 422 and the lip sealing surface 454. The
shoulders 448 may
include generally axially facing surfaces that extend transversely with
respect to the axis A.
in a first example, the shoulders 448 may be disposed in a plane perpendicular
to
the central axis A. In this example, the shoulders 448 may be coplanar with a
step-down 448'
extending circumferentially between the shoulders 448 such that a
circumferentially continuous
step-down surface may be established by the shoulders 448 and the step-down
448'.
As illustrated in FIG. 23A, the shoulders 448 may be produced in a blank mold
by
corresponding surfaces of a neck finish guide ring G. The mold may include a
neck ring N to at
least partially establish an exterior portion of the neck finish 434 of the
container 422, a plunger
P to at least partially establish an interior portion of the neck finish 434
including the spout walls
446 (thickened wall portions 466), and interior surfaces (e.g., interior
surface 462), and the guide
ring G that may establish the shoulders 448, sealing surface 454, and the
like.
In a second example, and with reference to Fla 27, shoulders 548 (one shown)
may be disposed at a non-perpendicular angle with respect to a longitudinal
central axis A,
extending in a direction axially inwardly into a container 522 and radially
inwardly toward the
6
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
longitudinal central axis of the container 522. In this illustrated example,
no additional
step-down may be provided. But other embodiments may include both the angled
shoulders
548 and a step-down extending circumferentially therebetween.
With reference to FIG. 27A, both the shoulders 548 and spout walls 546 (e.g.,
thickened wall portions 566) may be produced in a blank mold by corresponding
surfaces of a
plunger P'. The mold may include a neck ring N to at least partially establish
an exterior
portion of the neck finish 534 of the container 522, the plunger P to at least
partially establish an
interior portion of the neck finish 534 including the spout walls 546 /
thickened wall portions
566, and interior surfaces (e.g., interior surface 562), and a guide ring G'
that may establish the
sealing surface 554, and the like.
The embodiment of FIGS. 27 and 27A is similar in many respects to the
embodiments of FIGS. 1-29 and like numerals between the embodiments generally
designate like
or corresponding elements throughout the several views of the drawing figures.
Accordingly,
the descriptions of the embodiments are incorporated into one another, and the
description of the
.. common subject matter generally may not be repeated here.
Referring again to FIGS. 23, 23A, 27, and 27A, the shoulders 448, 548 are
axially
spaced from, or axially recessed with respect to, the planar sealing surface
454, 554. In fact, the
shoulders 448, 548 may be recessed an amount greater than would be provided
for a conventional
step-down of a conventional container. For instance, the step-down 448' may be
axially
recessed from the sealing surface 454 at least 0.020" and over 1 mm for a 35
mm finish.
To illustrate, with reference to FIG. 26, a package 420 includes the container
422
and a seal carrying closure 424 sealingly coupled to the container 422. The
closure 424
17
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
includes a lid 423 carrying a seal 425. The lid 423 may include a base wall
423a, a skirt 423b
extending axially from the base wall 423a and including one or more container
engagement
features 423c for coupling to the corresponding features 442 of the container
422. The base
wall 423a may include one or more peripheral panels 423d radially adjacent and
extending
radially inwardly from the skirt 423b, and one or more central panels 423e
extending radially
inwardly from the peripheral panel(s) 423d and recessed or extending axially
inwardly from the
panel(s) 423d. The seal 425 may be carried by the peripheral panel(s) 423d and
generally
radially between the skirt 423b and the central panel(s) 423e.
The shoulders 448 (and 548) may be recessed to such an extent that when the
closure 424 is fully coupled to the container 422, as illustrated in FIG. 26,
there is axial clearance
between the shoulders 448 and the central panel 423e and, more specifically,
there may be axial
clearance between the shoulders 448 and the seal 425. Accordingly, there may
be no
interference between the shoulders 448 and the lid 423 and/or the seal 425. In
the illustrated
example, the lid 423 may be composed of a metallic material and the seal 425
may be composed
of a polymeric material. In other examples, the lid 423 and the seal 425 may
be composed of
any suitable materials.
With continuing reference to FIG. 26, the thickened wall portions 466 may
extend
from the shoulders 448 axially into the container 422, past the engagement
feature(s) 442 and/or
flange 444. For example, the portions 466 may extend to a shoulder 432 of the
container 422 to
establish a thickened shoulder portion 432'. In another example, the portions
466 may further
extend axially to a sidewall 430 of the container 422 to establish a thickened
sidewall portion
430'. Accordingly, the spout walls 446 or thickened wall portions 466 may
include interior
18
CA 02911091 2015-10-30
WO 2014/179006 PCT/US2014/033483
surfaces 468 of the container neck finish 434, interior surfaces 460' of the
thickened shoulder
portion 432', and interior surfaces 458' of the thickened sidewall portion
430', at least at
locations corresponding to and axially beneath the shoulders 448. In any case,
the thickened
wall portions 466 extend radially inwardly toward the central axis A with
respect to one or more
of the interior surfaces 462, 464 of the rear and/or trough walls 450, 452 to
form an internal
trough of desired axial length to direct flow of product out of the container
422.
There thus has been disclosed containers that may provide improved product
flow
and that fully satisfies all of the objects and aims previously set forth. The
disclosure has been
presented in conjunction with several illustrative embodiments, and additional
modifications and
variations have been discussed. Other modifications and variations readily
will suggest
themselves to persons of ordinary skill in the art in view of the foregoing
discussion.
