Beverage Can Closure Element
The invention relates to a beverage can closure element
according to the generic term in claim 1.
The invention relates to a beverage can lid with a beverage
can closure element of this type and a beverage can with a
beverage can lid of this type.
Next to bottles, beverage cans are the most important retail
packaging for beverages and generally also serve as a
drinking vessel. They are primarily used for carbonated
beverages such as canned beer and soft drinks.
Beverage cans generally consist of a single-piece,
cylindrical container made of aluminium or tinplate, a
seamed lid made of aluminium with an oval scored line or
rupture line and a riveted metal tab which, when raised,
depresses the scored oval into the interior of the can
through lever action, thus creating a pouring or drinking
opening.
The invention relates to a beverage can closure element
which is capable of closing and locking an opening of any
CA 02795237 2012-10-02
2/100 -
type and releasing said opening again, all in a simple
manner. The invention relates in particular to a lid for a
container such as a beverage can, where the lid consists of
plate, preferably tinplate. Beverage cans generally have a
rupture line in the lid. An opening tab fixed to the lid can
produce a dispensing opening by the action of a rupture
lever on the rupture line.
Beverage cans of this type primarily contain liquids such as
beer, lemonade, fruit juices, mineral water or similar, but
can also be used for sauces, herb mixtures, grated cheese,
nuts or similar.
The disadvantage of familiar beverage cans is that they
cannot be closed again after opening. This means that there
is a risk of residual contents being spilt in the workplace,
in vehicles, when playing, etc. Furthermore, contaminants
and insects may enter the can.
WO 2006/009483 reveals a reclosable lid according to the
generic term in claim 1 and claim 7. In this embodiment of
the lid, the opening tab can be pivoted after opening to
close the dispensing opening. The opening tab has a ring-
shaped sealing medium such as a magnet, adhesive, rubber or
plastic seal on its underside for this purpose. As several
materials are used here in the manufacture of the lid, the
production of a lid of this type is cost and labour-
intensive.
US 4,673,099 also reveals a reclosable lid according to the
generic term in claim 1 and claim 7. The opening tab is
slanted outwards on its underside to close the dispensing
opening. This slant enables it to engage in the dispensing
opening. A separate sealing material (e.g. elastomer) is
also used here to ensure the achievement of an effective
seal. Consequently, the manufacture of the lid is also cost
and labour-intensive in this case.
CA 02795237 2012-10-02

The object of the invention is therefore to further develop
a lid of the type mentioned above in such a way as to enable
its cost-effective manufacture and whereby the dispensing
opening is easy to close and lock and also easy to reopen
again.
The object of the invention is achieved with a beverage can
closure element according to the characteristics of claim 1.
Preferred embodiments of the invention are stipulated in the
dependent claims.
According to the invention, a beverage can closure element
with a cover element is specified for configuring in an
opening in a beverage can and a locking mechanism embodied
and/or configured on the cover element which is embodied
and/or configured in a manner that the beverage can closure
element configured in an opening in a beverage can can be
locked in an opening of a beverage can, with the cover
element being embodied and configured so that, if the
beverage can closure element is configured in an opening of
a beverage can, the cover element is elastically deformable
between at least two states, whereby the locking mechanism
is configured and embodied in such a manner on the cover
element that the locking mechanism in at least one state of
the cover element of the at least two states of the cover
element is configured further inwards in a radial direction
relative to the cover element than in at least one other of
the at least two states of the cover element.
According to the invention, the cover element can be
elastically deformable through the external application of
force between the at least two states.
According to the invention, the cover element can be
elastically deformable through interaction with the beverage
can between the at least two states.
CA 02795237 2012-10-02
4/100 -
According to the invention, the locking mechanism can be
configured and/or embodied on the underside of the cover
element. The underside of the cover element is the side of
the cover element turned towards the contents of the
beverage can when the beverage can closure element is
configured in the opening of the beverage can to close the
beverage can again.
Alternatively or additionally, the locking mechanism can be
configured and/or embodied on the upper side of the cover
element.
Alternatively or additionally, the locking mechanism can be
configured and/or embodied on the upper side of the cover
element.
According to the invention, the cover element can be
embodied as a disc spring design.
According to the invention, the cover element can exhibit a
surface section embodiment which is curved upwards in one of
the states and curved downwards in another of the states.
Variants and alternatives are conceivable. For example,
depressions or level sections or grooves and/or ribs can be
included in the curvature. The transition from a level
surface to an curved surface or vice versa is also
conceivable. The transition from a gentler curvature to a
more severe curvature or from a more severe curvature to a
gentler curvature is also conceivable.
According to the invention, the cover element can exhibit at
least one and preferably several reinforcing ribs and/or
reinforcing grooves.
According to the invention, the locking mechanism can
exhibit at least one and preferably several locking elements
CA 02795237 2012-10-02
5/100 -
which should preferably be embodied as a completely or
partially circumferential rim or rims that run or runs
around the cover element and/or as a lug or lugs.
Locking mechanism locking elements of this type can be
preferably embodied and configured so that they engage
behind the rim of the beverage can opening in the locked
state and, consequently, can lock the beverage can closure
element in the opening.
According to the invention, the locking mechanism can
comprise one and preferably several extensions configured on
the cover element.
According to the invention, the cover element can be
configured in a ring-like component that encloses the rim of
the cover element, whereby extensions are preferably
embodied on the cover element, which are accommodated in
slots embodied in the ring-like component.
The extensions can act as a locking mechanism in this
embodiment of the invention in that they move outwards in a
radial direction through the slots of the ring-like
component when the cover element is pressed, resulting in
the locking of the beverage can closure element in the
dispensing opening. In the case of this embodiment of the
invention, the cover element and its extensions and the
ring-like component should preferably be manufactured with
the same material as the beverage can lid and the beverage
can. However, it would also be conceivable that the
components could be made of other materials, for example and
preferably plastic which is compatible with foodstuffs. The
components can be made of the same or different materials in
this respect.
According to the invention, the beverage can closure element
can exhibit an unlocking mechanism embodied and configured
CA 02795237 2012-10-02
- 6/100 -
so that the locking mechanism is unlocked when the unlocking
mechanism is actuated, preferably through elastic
deformation of the cover element in the state in which the
locking elements are still configured inwards in a radial
direction.
This means that the beverage can opening can be cleared
again after the unlocking mechanism is actuated. In other
words, the elastic deformation of the cover element that
occurs during locking can be reversed again with the
unlocking mechanism by applying a force to the cover element
in such a manner that the cover element reverts from one
stable state (i.e. the locking state, for example) to
another stable state (i.e. the unlocking state, for example)
which corresponds to the state in which the cover element
was configured for locking in the opening of the beverage
can. The cover element can be removed again from the
beverage can opening following unlocking and pivoted into
another position to clear the opening again to enable
further dispensing of the contents of the beverage can.
According to the invention, the unlocking mechanism can
encompass a lever configured on the beverage can closure
element or a mechanism with one or more wings configured on
the beverage can closure element.
Alternatively or additionally, the reversal of the elastic
deformation of the cover element of the beverage can closure
element cover element can be achieved by actuating the
beverage can closure element itself.
According to the invention, the cover element can exhibit a
curved surface or partial surface, preferably an upwardly
curving surface or partial surface, whereby the embodiment
of the surface and/or partial surface is preferably round,
oval, trapezoidal with rounded corners, bridge shaped,
groove shaped, rectangular, square, triangular, polygonal or
CA 02795237 2012-10-02
= - 7/100 -
similar.
The curved surface or partial surface of the cover element
can, of course, also exhibit any other suitable shape,
particularly a shape with rounded corners.
According to the invention, the cover element can exhibit a
curved surface or partial surface directed downwards, or
exhibit an upwardly curving surface which in part
encompasses a surface directed downwards.
According to the invention, the cover element can exhibit a
rim as a locking element, whereby the rim is a completely or
partially circumferential rim or encompasses one or more
projecting parts.
According to the invention, the cover element can exhibit a
completely or partially circumferential reinforcing groove
and/or reinforcing rib, for example in the form of an
offset.
This embodiment has the advantage that the stability of the
cover element is enhanced, whereby locking in the dispensing
opening is easier to manage and more reliable.
According to the invention, the rim of the cover element can
exhibit one or more lugs.
This enables the achievement of better (i.e. simpler) and
more reliable locking of the cover element in the dispensing
opening.
According to the invention, the cover element can exhibit a
level surface or a surface protruding from a level surface,
whereby the surface protruding from the level surface is
preferably a curved surface or a surface with multiple
curves.

The preferred embodiment of the cover element is such that
it is the part of the opening tab or the beverage can
closure element, which can close the dispensing opening of
the beverage can again.
The invention also relates to a beverage can lid with a
beverage can closure element according to the invention,
preferably with a rupture line defining a dispensing opening
for dispensing the contents of the beverage can.
According to the invention, the beverage can closure element
can be configured and embodied as an opening tab for opening
the beverage can by pressing in the beverage can lid on the
rupture line.
This is the preferred embodiment of the invention.
Alternatively, the beverage can closure element can also be
planned as a component or part separate from an opening tab.
It is evident that, according to the invention, the beverage
can closure element can also be planned as a part separate
from the beverage can. However, an embodiment of the
beverage can opening tab as a beverage can closure element
according to the invention is preferred. To this end, the
beverage can closure element has the double function of an
opening tab for the initial opening of the beverage can and
an element to close the beverage can again, locking the
beverage can closure element in the beverage can opening
created by opening the beverage can along the rupture line.
According to the invention, the beverage can closure element
can be configured and embodied in such a manner on the
beverage can lid that, following opening of the dispensing
opening, the beverage can closure element can be configured
over the dispensing opening, either through pivoting and/or
folding down the beverage can closure element to cover and
close the dispensing opening again.
CA 02795237 2012-10-02

According to the invention, the rim of the beverage can
closure element can be configured and embodied in such a
manner that it snaps into the dispensing opening (4) when
closing the dispensing opening (4), is clamped tightly in
the dispensing opening (4) or engages in said.
According to the invention the beverage can lid can at least
exhibit a groove and/or depression for the inclusion of a
rib, beading and/or lug embodied at the beverage can closure
element. This feature can offer the advantage of a better
and more space-saving stackability and storage of beverage
can lids in the manufacture of beverage cans. According to
the invention the groove and/or depression can preferably be
embodied circular, whereby the groove and/or depression can
be embodied in a continuous and/or interrupted way.
According to the invention the beverage can lid can exhibit
a bubble for including the beverage can closure element.
This embodiment of the invention offers the advantage that
the beverage can closure element cannot simply be pressed
through unintentionally, but can be supported by the
suitably configured bubble. According to the invention the
bubble can preferably be configured kidney-shaped, circular
or according to the shape of the closure element. In
addition, according to the invention the bubble can
preferably exhibit a recess, arranged in the direction of
the opening section as viewed from the bubble. This further
embodiment has the advantage that the beverage can closure
element can be arranged above the opening section of the
beverage can lid without being obstructed by the bubble.
According to the invention the area of the beverage can lid
below the beverage can closure element (bubble) can be
marked, preferably by different colours in red, blue,
yellow, green or another preferably clearly recognizable

CA 02795237 2012-10-02
- 10/100 -
invention has the advantage that the consumer can easily
recognize whether the beverage can is still new and/or
unopened or already reclosed, if no opening of the beverage
can be seen, because only in case of the reclosed beverage
can will the marked area be visible, as it is covered by the
beverage can closure element in case of a new and/or
unopened beverage can.
According to the invention the beverage can lid can exhibit
a pre-impression and/or curvature, preferably configured
such that the beverage can lid is largely level, at least in
the area of the opening section after manufacturing
the beverage can with the beverage can lid, after filling
the beverage can and after opening the beverage can. This
embodiment of the invention has the advantage that the
beverage can closure element can better reclose the opening
section of the beverage can. Alternatively or additionally
the beverage can closure element can be embodied such that
it exhibits a curvature, corresponding to the curvature of
the opening section after opening the beverage can.
Alternatively or additionally the beverage can closure
element and/or the beverage can lid can be configured in
such a flexible way in the area of the opening section that
the curvatures of the beverage can closure element and the
beverage can lid adapt to the beverage can when reclosing
it.
Alternatively or additionally the tolerance ranges of
sealing elements could be configured such that possible
different curvatures of the beverage can closure element
and/or beverage can lid in the area of the opening section
when sealing the opening section by the beverage can closure
element are within the tolerances. According to the
invention the pre-impression and/or curvature can be
embodied here at least in the area of the beverage opening.
According to the invention a seal can be included at the
beverage can closure element.
CA 02795237 2012-10-02
= - 11/100 -
According to the invention a sealing band can be provided at
the beverage can closure element, preferably at least partly
or completely arranged in a reinforcing profile. The sealing
band can be embodied as a coating, for example.
According to the invention the beverage can closure element
can exhibit a buckling line. According to the invention the
buckling line can be provided by a pinch and/or a depression
on the upper and/or lower side of the beverage can closure
element to facilitate the deformation for reclosure and/or
re-opening of the beverage can.
According to the invention the beverage can closure element
is embodied of several materials and preferably exhibits a
plastic overmoulding or plastic bubble.
According to the invention the beverage can closure element
can exhibit plastic lugs in the cover element.
According to the invention the beverage can closure element
can exhibit plastic lugs at least in the cover element.
According to the invention the beverage can closure element
can exhibit bimetal on the whole surface or at least in a
section and preferably in the area of the cover element
and/or it can be embodied of bimetal.
According to the invention the beverage can closure element
can at least exhibit a reinforcement.
According to the invention the reinforcement can be
configured in a dome- and/or tubular shape. The
reinforcement can be configured, for example, at the rim of
the cover element and/or at the rim of the beverage can
closure element. The reinforcement can be configured upward
and/or downward, i.e. in the direction of the beverage can
lid.
CA 02795237 2012-10-02
- 12/100 -
According to the invention the beverage can closure element
can exhibit a lug, embodied at the rim of the extension.
This embodiment of the invention has the advantage that the
beverage can can be opened more easily, as the area of the
beverage can closure element which presses on the beverage
can lid when opening the beverage can to open the beverage
can lid at the predetermined rupture point, is reinforced by
the lug and can exert higher pressure on certain points on
the area of the predetermined rupture point.
According to the invention at least one and preferably
several leverage points can be embodied in the beverage can
closure element, whereby in the beverage can lid preferably
depressions are embodied for including the leverage point
and/or leverage points.
According to the invention conical or continuous leverage
points or leverage point of any shape (round/rectangular,
any shape, any positioning) can be fit in the tab or the
beverage can lid to ensure easier opening by the opening
lever. These opening leverage points can, for example, be
hidden each in the stamped depressions of the lid and become
active only after opening and turning the tab. The leverage
points/areas remove the tension from the curvature and can
be fit at any point on the lid or tab.
According to the invention at least a depression can be
embodied in the cover element of the beverage can closure
element. This embodiment of the invention has the advantage
that by including depressions the tension on the "tip" of
the dome of the cover element can be reduced and the height
can be minimized. The depressions can have any shape
considered to be suitable by a person skilled in the art.
For example, in the middle of the cover element an
essentially round depression and/or an essentially circular
groove and/or depression arranged around the center of the
CA 02795237 2012-10-02
- 13/100 -
cover element can be included.
According to the invention a curvature can be configured in
the beverage can closure element, exceeding the rim of the
opening section to be covered when reclosed. This embodiment
of the invention has the advantage that the curvature will
exceed the opening rim when reclosing the beverage can,
resulting in an "upward movement" of the rims. By suitable
constructional elements of the tab, the opening element can
be placed higher and an opening mechanism can be provided.
According to the invention a circumferential undulation can
be embodied around the cover element and/or the opening
section in the beverage can closure element and/or the
beverage can lid. This embodiment of the invention has the
advantage that a good sealing of the reclosed beverage can
can be provided by a simple way with low manufacturing
costs.
According to the invention the beverage can closure element
can exhibit a coating with a sealing lip and/or sealing
bead. According to the invention the coating and/or the
sealing lip and/or the sealing bead can be embodied of
plastic and/or silicone and/or rubber.
According to the invention the beverage can closure element
can exhibit a spreader ring at its rim, preferably
exhibiting knobs and/or lugs.
According to the invention the predetermined rupture line in
the beverage can lid can include a ligament for the opening
section which keeps the opening section of the beverage can
lid connected to the beverage can lid after opening the
beverage can.
According to the invention the beverage can closure element
can exhibit a spreader ring and/or knobs for sealing the
CA 02795237 2012-10-02
- 14/100 -
beverage can closure element against the beverage can lid
when reclosing the beverage can, whereby preferably at least
a wider knob or lug and/or at least a continuous material
area is included which is provided opposite to an area of
the beverage can lid when reclosing the beverage can, at
which the opening section of the beverage can lid will
remain connected with the beverage can lid after opening the
beverage can.
According to the invention the beverage can closure element
can exhibit at least one and preferably several recesses,
whereby the recess(es) is (are) preferably embodied as cut-
out, in addition preferably such that a part of the beverage
can closure element goes downward in such a way that when
reclosing the beverage can, it catches at the rim of the
opening in the beverage can lid which was formed at the
predetermined rupture line when opening the beverage can
According to the invention, the reopening mechanism can
consist of a rupture lever exhibited by the beverage can
closure element which is used as a reopening lever, or that
the reopening mechanism consists of one or more wings fixed
to the opening tab or embodied as a single part with the
opening tab, whereby the wing(s) is/are manufactured from
the same material as the opening tab or a material other
than that of the opening tab.
Alternatively or additionally, the reopening mechanism can
also consist of the configuration of an opening mechanism on
the other side of the opening tab opposite the rupture lever
which can be used as an auxiliary opening mechanism or main
opening mechanism, whereby the rim of the opening tab or one
or more wings can be used for reopening.
According to the invention, the upper side of the opening
tab or beverage can closure element can, in terms of shape
and surface quality, be designed so that it can be used for
CA 02795237 2012-10-02
- 15/100 -
advertising purposes, images, logos, numbering, etc.
The invention also relates to a beverage can with a beverage
can lid according to the invention and/or a beverage can
closure element according to the invention.
According to the invention, the beverage can can be
manufactured from metal, preferably tinplate, and/or plastic
and/or a combination of different materials.
According to the invention, the beverage can can be used for
beverages, granular and/or powdered products, sauces, nuts
or other products.
The beverage can lid according to the invention can, for
example, be produced in a manner where the lid is initially
pressed in a conventional manner, but forming the opening
tab so that it can be inserted into the dispensing opening
and locked and that it can be raised easily out of the
dispensing opening again to clear the opening. The rim
provided for locking can be embodied as a completely or
partially circumferential rim in this respect, or consist of
one or more projecting parts, and/or a completely or
partially circumferential reinforcing groove can be provided
which ensures greater opening tab stability and better
locking in the dispensing opening. Furthermore, the opening
tab can be pressed in a manner where one or more wings
is/are moulded as a single part or that one or more wings
is/are fixed to the opening tab.
When handling the beverage can according to the invention,
the said beverage can can be opened using the opening tab,
after which the opening tab is pivoted or folded through
180 to close and lock the dispensing opening, whereby the
locking elements of the beverage can closure element are,
through deformation of a beverage can closure element
surface, moved outwards in a radial direction relative to
CA 02795237 2012-10-02
16/100 -
the surface to lock the dispensing opening, and the
mechanism for reversing this deformation is actuated by
moving the locking elements inwards in a radial direction
relative to the surface to clear the opening again.
In some embodiments of the invention, an upwardly curving
surface of the opening tab can be pressed downwards to lock
the dispensing opening in a manner in which the curvature
reverses, whereby the opening tab snaps into the dispensing
opening and locks the lid, or that the upwardly curving
surface is pressed downwards in a manner in which the
curvature is lessened or becomes completely flat, whereby
the opening tab stretches and the rim of the opening tab is
pressed outwards, and whereby the opening tab snaps into the
dispensing opening and locks the lid.
In some embodiments of the invention, the lug or lugs can
clamp on the rim of the opening tab or engage in this
position to lock the dispensing opening.
The opening tab or the cover element can, for example, be
pressed downwards to lock the dispensing opening, this being
realised in a manner that causes the curvatures of the
curved surface to reverse (i.e. the upwardly curving surface
curves downwards and the downwardly curving surface or
partial surface curves upwards), whereby the opening tab or
the cover element or the beverage can closure element snaps
into the dispensing opening and locks.
The rupture lever can be used as a reopening lever to reopen
the beverage can, whereby the rupture lever, which was
pivoted together with the opening tab or beverage can
closure element, is pressed downwards, whereby the snapped-
in rim is pressed inwards again and the curved surface,
which was less curved or even flat in the snapped-in state,
is pressed upwards again, whereby the opening tab and
beverage can closure element are released from the
CA 02795237 2012-10-02
- 17/100 -
dispensing opening and can be pivoted or folded back.
Alternatively or additionally, an opening mechanism can be
provided or used for reopening which is located on the other
side of the opening tab opposite the rupture lever, whereby
the rim of the opening tab or one or more wings can be used
to loosen the opening tab.
The wing(s) can be pressed downwards to reopen the
container, whereby the opening tab or the beverage can
closure element returns to its original shape, or whereby
the wing(s) is/are raised and pulled upwards.
Following opening of the beverage can, the opening tab or
beverage can closure element or beverage can closure element
can be pivoted or folded and pressed into the dispensing
opening. Locking elements can be provided to avoid
situations where the opening tab or the beverage can closure
element loosens out of the dispensing opening, and a
reopening mechanism can be provided to enable clearing of
the dispensing opening again.
The opening tab used for reclosing or the beverage can
closure element used for reclosing can be accommodated
without difficulty in the disc-shaped cavity which opens
upwards and is formed between the central lid component and
the upper can rim, particularly if the tab or closure
element consists of a thin plate stamped part. This means
that according to the invention the lid can be produced by
conventional machines without the need for major
adaptations.
The dispensing opening can be reliably closed and locked,
and dirt, dust and pests (i.e. insects) cannot penetrate
into the can after it has been opened. The contents can no
longer be spilled in appreciable quantities in the
CA 02795237 2012-10-02
18/100 -
workplace, when playing or when travelling in moving
vehicles. The subject matter of the invention can even be
closed and locked to a degree that prevents the contents of
the can being spilled in appreciable quantities if the can
topples over. A can equipped in this manner is also very
environmentally friendly, as the opening tab or the beverage
can closure element used for reclosing is continually
connected to the can.
The embodiment of the locking elements is such that the
opening tab or beverage can closure element or beverage can
closure element snaps into the dispensing opening and locks
during reclosing. The opening tab or beverage can closure
element should preferably exhibit an upwardly curving
surface or partial surface in this respect and should
preferably have a circumferential rim which can snap into
the dispensing opening. The surface or partial surface can
be round, oval, trapezoidal with rounded corners, bridge
shaped, groove shaped, rectangular, square, triangular,
polygonal or similar, with rounded corners if necessary. The
surface or partial surface can also consist of combinations
of different shapes (e.g. angular and rounded shapes).
The curved surface or partial surface can also be directed
downwards, or the upwardly curving surface can in part
exhibit a surface directed downwards. The surface or partial
surface directed downwards facilitates reclosing and
locking.
Locking can be achieved as follows in the case of some
embodiments of the invention: the upwardly curving surface
is pressed downwards in a manner in which, due to this
deformation, the curved surface presses the rim of the
opening tab or beverage can closure element or beverage can
closure element outwards in a radial direction; the opening
tab or the beverage can closure element snaps into the
dispensing opening and shuts the lid. The engaging rim can
CA 02795237 2012-10-02
- 19/100 -
be a completely or partially circumferential rim, or consist
of one or more projecting parts. A completely or partially
circumferential reinforcing groove (e.g. in the form of an
offset, a depression or an elevation) can ensure greater
stability of the opening tab or beverage can closure element
and improved engaging in the dispensing opening.
In the case of some embodiments of the invention, the
reopening mechanism can involve use of a rupture lever (i.e.
the lever used to break open the rupture line) as a
reopening lever, whereby the rupture lever which was pivoted
or folded back together with the opening tab or beverage can
closure element is pressed downwards, whereby the snapped-in
and locked rim is pressed inwards again and the curved
surface, which is directed downwards in the snapped-in and
locked state, is pressed upwards again. The opening tab or
beverage can closure element releases itself from the
dispensing opening in this manner. The opening tab or
beverage can closure element can therefore be pivoted or
folded back to permit further emptying of the beverage can.
The curved surface, which was pressed downwards for locking,
can also be less downwardly curving or even flat in the
locked state.
Alternatively, the locking mechanism can consist of an
embodiment of the dispensing opening rim which enables firm
clamping or engaging of the opening tab or beverage can
closure element or beverage can closure element in the
dispensing opening during reclosure. The rim of the opening
tab or beverage can closure element or beverage can closure
element exhibits one or more lugs for locking in the
dispensing opening.
Alternatively, the reopening mechanism can consist of one or
more wings fixed to the opening tab or beverage can closure
element or embodied as a single part with the opening tab or
beverage can closure element. The wing(s) is/are
CA 02795237 2012-10-02
20/100 -
manufactured from the same material as the opening tab or
beverage can closure element or a material other than that
of the opening tab or beverage can closure element.
The part of the opening tab or beverage can closure element
which can reclose the dispensing opening should preferably
have a level surface or a surface raised above the level
surface. This surface protruding from the level surface can
be a curved surface or a surface with multiple curves and
can preferably constitute the cover element or a
considerable part of the cover element.
Additionally, the upper side of the opening tab or beverage
can closure element can, in terms of shape and surface
quality, be designed so that it can be used for advertising
purposes, images, logos, numbering, etc.
The invention also relates to a container with a closure
element or lid according to the invention, whereby the
container can be manufactured from an environmentally
friendly material such as metal, preferably tinplate, or
plastic or a combination of different materials. A container
of this type can be used for beverages, granular or powdered
products, sauces, nuts or other products.
Where the container is a beverage can, the lid, and
particularly the opening tab or beverage can closure
element, can exhibit a hole or several holes through which
tubular objects (e.g. drinking straws) can be inserted.
The invention also encompasses a process for the manufacture
of a lid, whereby the lid is initially pressed in a
conventional manner, but forming the opening tab or beverage
can closure element so that it can be inserted into the
dispensing opening. The opening tab or beverage can closure
element exhibits a circumferential rim in this respect which
can snap into or engage in the dispensing opening, or be
CA 02795237 2012-10-02
- 21/100 -
clamped firmly therein. Alternatively the rim of the opening
tab or beverage can closure element can exhibit one or more
lugs.
The invention also encompasses a process for opening,
reclosing and reopening the container. The rupture lever,
for example, can be pressed downwards for reopening, whereby
the rim locked though snapping, engaging or clamping is
released and the opening tab or beverage can closure element
can be pivoted or folded back. Alternatively, one or more
wings can be provided for opening and also reopening the
container to enable release of the opening tab or beverage
can closure element.
Although the invention relates in particular to a lid for a
beverage can, other applications are also possible, e.g. as
a beverage can closure element for temporarily closing
bottles or similar containers or as a cover for objects such
as camera lenses or similar.

Fig. 1 illustrates a schematic top view of a beverage can 30
with a beverage can lid 20 and beverage can closure element
according to an initial embodiment of the invention. The
beverage can closure element 10 exhibits a rim area 11 and
cover element 12 suitable for covering the opening in the
beverage can 30 after the beverage can is opened.
Furthermore, the beverage can closure element 10 exhibits an
extension 13, which extends the rim area 11 on one side. A
rivet 14 is provided in the wider rim area created by the
extension, which preferably forms a pivoting axis for the
beverage can closure element 10. Furthermore, a penetration
line 15 is provided in the extension 13, which allows the
beverage can closure element to be folded upwards to open the
beverage can 30.
The beverage can 30 is a two-part structure and exhibits a
beverage can lid 20. The beverage can lid 20 encompasses an
essentially level lid section 21 and opening section 23
enclosed by a rupture line 22. The opening section 23 is
broken out of the lid section 21 along the rupture line 22 in
a known manner when the beverage can is opened.
Furthermore, the beverage can lid 20 exhibits a seam section
24 with which the beverage can lid can be fitted to the body
of the beverage can in a known manner.
Furthermore, the beverage can lid 20 exhibits a groove 25
between the lid section and the seam section 24 which
collects any emerging liquid and prevents it flowing back
into the beverage can.
The beverage can 30 is essentially a cylindrical structure
and exhibits a cylindrical section 32 which transforms into a
conical tapered section 31 in the upper area, thus enabling
stacking of the beverage can 30 in the known manner.

According to the embodiment examples of the invention
illustrated in Figures 1 and 2, the embodiment of the cover
element 12 of the beverage can closure element is an upwardly
curving surfaced relative to the beverage can (whereby the
top of the can is the side exhibiting the beverage can lid),
whereby the size and shape of said essentially corresponds to
the opening section 23 of the beverage can lid 20 and the
opening of the opened beverage can.
Figures 1 and 2 illustrate the beverage can prior to initial
opening with the opening section 23 still contained in the
beverage can lid 20, as can best be discerned in the
sectional view from Fig. 2.
The body of the beverage can is only partially illustrated as
a dashed line in the partial sectional view from Fig. 2.
Figures 3 and 4 illustrate the beverage can illustrated in
Figures 1 and 2 after opening, i.e. after the opening section
23 has been broken out of the beverage can lid 20 along the
rupture line 22 in the known manner. Opening can, for
example, be achieved by bending the beverage can closure
element 10 upwards to press the opening section with the
extension 13, this then been broken out of the beverage can
lid 20 along the rupture line 22 as a consequence of the
pressure exerted by the extension 13.
Naturally enough, another opening mechanism that is known in
the art or more obvious can be provided according to the
invention. For example, the beverage can closure element can
also not be embodied as part of the opening mechanism. The
penetration line 15 can be dispensed with in this case, as it
is no longer necessary that the embodiment of the beverage
can closure element should facilitate bending upwards.
Figures 5 and 6 illustrate the embodiment example of the
CA 02795237 2012-10-02
51/100 -
invention with a beverage can closure element 10 pivoted
through approx. 90 degrees. The beverage can closure element
is configured to enable pivoting around the rivet 14, i.e.
the rivet 14 defines a pivoting axis around which the
beverage can closure element 10 can be pivoted. This
pivotable configuration is known in the art from the familiar
opening tabs articulated with a rivet on beverage can lids.
Figures 7 and 8 illustrate the beverage can 30 from Fig. 1
with the opening section of the beverage can lid 20 broken
out, whereby the beverage can closure element 10 is pivoted
over the beverage opening or the area of the beverage can
lid 20 from which the opening section 23 has been broken out
along the rupture line 22. The hand 1 of a user who wishes
to close the opened beverage can 30 again with the beverage
can closure element 10 is depicted schematically in Fig. 8.
Furthermore, locking elements 16 are schematically
illustrated in Fig. 8 which engage under the lid section 21
of the beverage can lid 20 when the beverage can 10 is
closed again, tightening the beverage can closure element 10
on the beverage can lid 20. In order to close the beverage
can again, the user need only pivot the beverage can closure
element 10 around the rivet 14 into the position illustrated
in Figures 7 and 8 and press with one finger 1 on the cover
element 12 of the beverage can closure element 10 to
transform it into the state illustrated in Figures 9 and 10.
Figures 9 and 10 illustrate the beverage can 30 from Fig. 1
with the punched-out opening section 23 of the beverage can
lid 20, whereby the beverage can closure element 10 was
pressed into the beverage opening or the area of the
beverage can lid 20 out of which the opening section 23 was
broken to reclose the beverage can 30 initially opened in
this manner, whereby the finger 1 of a user who has closed
the opened beverage can 30 again with the beverage can
closure element 10 is depicted schematically.
CA 02795237 2012-10-02
- 52/100 -
The cover element 12 of the beverage can closure element 10
is transformed from the upwardly curving shape illustrated in
Figures 1 to 8 into the downwardly curving shape illustrated
in Figures 9 and 10 through the pressure of the finger 1. In
other words, the cover element is transferred from one stable
equilibrium into another stable equilibrium. In the
downwardly curving shape illustrated in Figures 9 and 10, the
cover element 12 also tends to assume as relaxed a shape as
possible, whereby the cover element is curved approximately
as far downwards as it was previously curved upwards, as
illustrated in Figures 1 to 8. The locking elements 16 are
pushed upwards against the lid section 21 of the beverage can
lid 20 as a result. The beverage can closure element is
braced against the beverage can lid 20 by the locking
elements 16, as the cover element 12 of the beverage can
closure element 10 cannot completely assume the relaxed
downwardly curving shape because the locking elements push
against the cover element 21 of the beverage can lid 20.
The manner in which the locking elements 16 brace the
beverage can closure element 10 against the beverage can lid
20 on the opening rim defined by the rupture line 22 can be
identified better in Fig. 11, particularly in the greatly
enlarged sections illustrated.
The user closes the opening by pressing with the finger 1 on
the cover element 12 of the beverage can closure element 10
in the direction of arrow A. The extension 13 is also moved
upwards in the direction of arrow B as a result.
Unlocking can be achieved if the user exerts force on the
extension 13 in the direction of arrow C as illustrated in
Fig. 12. This exerts force in the direction of arrow D (see
Fig. 13) on the cover element 12 of the beverage can closure
element in a manner which reverts the cover element from its
downwardly curving shape into its upwardly curving shape
again, as illustrated in Fig. 13. As a consequence of the
CA 02795237 2012-10-02
- 53/100 -
upwardly curving shape, the locking elements fitted to the
cover element are offset inwards in a radial direction
relative to the cover element and, as a result, no longer
engage under the rim of the lid section 21, permitting
pivoting of said back into the position illustrated in Fig. 1
or the position illustrated in Fig. 5 in which the opening
for drinking or dispensing of the liquid is cleared again.
Figures 14 to 17 illustrate a further embodiment of the
invention that essentially corresponds to the embodiment in
Figures 1 to 13. Identical reference signs are used to
designate identical components. Reference is made to the
description of the previous embodiment examples. Only the
differences to the previous embodiment example are described
below.
The beverage can 30 is illustrated in Figures 14 to 17 in a
position in which the opening in the beverage can lid 20
which has already been opened at least once has been closed
again using the beverage can closure element 10 pivoted over
the opening and brought into a locked position by pressing
the cover element 12 of the beverage can closure element.
The beverage can closure element 10 exhibits two opening
sections 17 and reinforcing beading 18 in the rim area 11.
The user can unlock the beverage can closure element 10 again
by exerting a force in the direction of arrow E on the
opening sections 17 with the fingers 1, 2, enabling clearing
of the opening again through pivoting of the beverage can
closure element 10 around the axis defined by the rivet 14.
Figures 18 to 23 illustrate a further embodiment of the
invention that essentially corresponds to the embodiment in
Figures 1 to 13 and 14 to 17. Identical reference signs are
used to designate identical components. Reference is made to
the description of the previous embodiment examples. Only the
differences to the previous embodiment example are described
CA 02795237 2012-10-02

below.
The beverage can closure element 10 exhibits two wings 19 and
reinforcing beading 18 in the rim area 11. The user can
unlock the beverage can closure element 10 again by exerting
a force in the direction of arrow E on the wings 19 with at
least one finger 1, enabling clearing of the opening again
through pivoting of the beverage can closure element 10
around the axis defined by the rivet 14.
Figures 7 to 11 illustrate how the opening tab or beverage
can closure element 10 is pressed into the dispensing opening
and how the rim of the opening tab or beverage can closure
element 10 is snapped into and locks the dispensing opening.
A force is exerted on the cover element 12 in the direction
of arrow A for this purpose, raising the extension 13 in the
direction of arrow B. The locking element 16 clamps behind
the rim of the dispensing opening defined by the rupture line
22 during this.
Figures Fig. 12 and 13 illustrate how the opening tab or
beverage can closure element 10 is released from the
dispensing opening so that the dispensing opening can be
cleared again by pivoting or folding back the opening tab or
beverage can closure element.
Figures 14 to 17 illustrate a variant of the opening
mechanism according to Figures 12 to 13, which can also be
used as an auxiliary opening mechanism.
Figures 18 to 21 illustrate a variant of the embodiment of
Figures 14 to 17, whereby two wings 19 strengthen the lever
action of the opening mechanism.

to the lug shapes illustrated in the other figures.
It is known in the art from Figures 65 to 71 that different
shapes of lid openings can be combined with different shapes
of the curved surface of the opening tab or beverage can
closure element 10.
Figures 72 to 75 illustrate possible cross section shapes,
which can match the embodiments of Figures 65 to 71.
Figures 76 to 81 illustrate further variants of the
embodiments of Figures 65 to 75 in section and plan views.
Figures 82 to 84 illustrate how the rivet 14, which acts as
the fixing and pivoting axis for the opening tab or beverage
can closure element, is stamped out of the lid material.
Figure 1 illustrates a plan view of a beverage can
manufactured as a cylindrical container from an aluminium
material. The beverage can 10 exhibits a lid 20 with an
opening tab or beverage can closure element 10. A rupture
line 22 is provided in the can lid 20 which marks out a
dispensing opening. The opening tab or beverage can closure
CA 02795237 2012-10-02
- 56/100 -
element 10 is preferably located in a horizontally pivotable
configuration in the middle of the can lid 20 in the area of
the rupture line 22 around a rivet 14 which forms an axis.
The rivet 14 is preferably stamped out of the same material
as the lid.
The opening tab or beverage can closure element 10 exhibits a
rupture lever (extension 13) in the area of the rupture line
22 overlaying and at least partially penetrating into the
area of the subsequent dispensing opening.
Figure 8 illustrates that the opening tab or beverage can
closure element 10 exhibits an upwardly curving surface
(cover element 12) and a circumferential rim (locking element
16) extending downwards.
Figures 1 to 13 illustrate how opening and reclosing of to
can lid 20 functions. Vertical upwards movement of the
opening tab or beverage can closure element 10 causes the
rupture lever to press on the part of the lid marked by the
rupture line 22, whereby the rupture line 22 breaks open and
dispensing opening is created.
The dispensing opening is closed by pivoting the opening tab
or beverage can closure element 10 by 180 around the axis
defined by to rivet 14, whereby the opening tab or beverage
can closure element 10 comes to rest over the dispensing
opening. The upwardly curving surface is then pressed
downwards into the dispensing opening, whereby the curvature
is reversed downwards. The locking elements are moved
outwards in a radial direction as a result, relative to the
cover element, whereby the opening tab or beverage can
closure element 10 snaps into the dispensing opening and
locks the lid 20. Opening, reclosing and locking of the
dispensing opening can be repeated as often as desired.
Figures 7 to 13 illustrate the functional principle of
CA 02795237 2012-10-02
- 57/100 -
opening, locking and reopening the lid. The rupture lever
moves upwards 13, as apparent in Figure 11, if the opening
tab or beverage can closure element 10 is pressed downwards,
as illustrated in Figure 8, and the rim 16 is snapped into
the dispensing opening. Figure 12, which corresponds to the
locked state according to Figure 11, illustrates how the lid
is opened again. The rupture lever 13 is pressed, as
illustrated in Figure 12, the opening tab or beverage can
closure element 2 curves upwards again, the locked rim 16 is
released and the dispensing opening can be cleared again
(e.g. using the rupture lever 13).
A support can be provided under the lever to be used which
can be used as a fulcrum for the lever action to increase
the lever action during reopening. A support of this nature
can be stamped out of the lid or rupture lever material or
fixed to either the lid or rupture lever as a separate part.
The support can also consist of two parts, on part on the
lid and one on the rupture lever.
An additional auxiliary opening mechanism, as illustrated in
Figures 14 to 23, can be provided in case the rupture lever
is, as a result of damage, no longer capable of reopening
the opening, or if the rupture lever has broken of partially
or completely. This auxiliary opening mechanism is
configured on the other side of the opening tab or beverage
can closure element opposite the rupture lever and
preferably has one of the forms implied in Figures 14 to 21,
but can also have any other desired form.
The auxiliary opening mechanism can also be used as the main
opening mechanism. If the opening mechanism is used (as an
auxiliary or main opening mechanism), one or both of the
sides 17 implied in Figures 14 to 17 is pressed, or one or
both of the wings implied in Figures 18 to 21. The opening
mechanism acts like a support here for the lever arm.
Figures 22 and 23 illustrate that the wings 19 are partially
CA 02795237 2012-10-02
- 58/100 -
directed upwards at an angle of, for example, 5 to 35 .
However, it is equally possible to direct the entire wing
upwards at this angle, or to direct part of the wing or the
entire wing upwards inclined at another angle.
Figure 1 illustrates a plan view of a lid shape, whereby the
surface or partial surface curved upwards is illustrated in
a round configuration. Further possible shapes are
illustrated in Figures 24 to 26, whereby Figure 27
illustrates possible cross section shapes. The shapes
illustrated in Figures 24 to 26 can be combined as desired
with cross section shapes of Figure 27. Aside from the
shapes illustrated here, other shapes can also be used.
Figures 27 g), 27 h) and 27 i) illustrate cross section
shapes with a reinforcing groove which is depicted as an
elevation or depression. Fig. 27 i) illustrates that an
additive 300 can be configured below the opening tab or
beverage can closure element, e.g. in the form of a powder,
a liquid or a tablet, preferably an effervescent tablet. The
additive can be contained by a film. A liquid seal is also
possible if a powder or tablet is involved, and a food
adhesive, such as starch or similar, can also be used in the
case of a tablet.
Figures 28a and 28b illustrate variants, whereby the opening
tab or beverage can closure element exhibits one or three
drinking straw holes. However, one or more drinking straw
holes can also be provided. Another option would be to
configure the drinking straw holes in the can lid instead of
the opening tab or beverage can closure element, or even in
both the opening tab or beverage can closure element and the
can lid.
Figures 29 to 32 illustrate an embodiment in which, in
addition to the preferred embodiment in which materials of
the beverage can are used, composite materials can also be
CA 02795237 2012-10-02
- 59/100 -
utilised. All conceivable metals and plastics can be used,
but preferably aluminium, sheet steel, rubber or substances
similar to rubber in any conceivable combination. The
surfaces of the materials used can be completely or
partially anodised. Figures 29 to 32 illustrate an
embodiment, whereby the opening tab or beverage can closure
element is, for example, an upwardly bent cover element with
four extensions 121 (or legs). The cover element can, under
practical circumstances, be a plastic or metal part, and one
or more legs can be provided. If the opening tab or beverage
can closure element are pressed into the dispensing opening
to close the opening, these legs move outwards in a radial
direction and press into the corresponding slots 111 of the
opening tab or beverage can closure element, whereby the
opening tab or beverage can closure element is locked in the
dispensing opening. The corresponding slots 111 in the
opening tab or beverage can closure element are as wide as
to broader tapered extensions 121 to achieve a good sealing
effect when pressing them in. Alternatively, the legs can
also exhibit another shape (e.g. rectangular). The
respective width of the slots should then be preferably
somewhat larger than the width of the legs. The legs 16 are
preferably somewhat longer than illustrated in Figure 17 to
ensure that the extensions 121 are positioned there where
the corresponding slots 111 are located, whereby the
extensions 121 already extend in part into the corresponding
slots 111 in the start position. Alternatively, other
locking options can be provided.
Figures 33 to 61 illustrate different locking options as
variants to those illustrated in Figures 7 to 10. The
locking elements consist of one or more lugs or a completely
or partially circumferential rim.
Figures 33 to 36 illustrate a locking design consisting of
three lugs 122. One or more lugs can be provided instead of
the illustrated lugs, or the same profile can also be
CA 02795237 2012-10-02
- 60/100 -
configured as a complete or partial circumferential rim.
Figure 34 is a section without lugs, Figure 35 a section
with lugs 122 and Fig. 36 illustrates the locked state.
Figure 33 also illustrates the corresponding opening tab or
beverage can closure element 10, whereby the opening tab or
beverage can closure element 10 can have any shape; the
upper part of the opening tab or beverage can closure
element is illustrated in Figure 33 as rectangular with
rounded corners, but it can have any other form, e.g.
curved, rectangular without rounded corners, triangular,
polygonal, elliptical, etc. In addition to the snapping-in
effect, a clamping effect also occurs in the case of this
locking design. During snapping-in of the lugs, the inclined
rim 8 is drawn somewhat downwards and clamped firmly in the
dispensing opening.
Figures 37 to 40 illustrate a variant as compared to the
embodiment in Figures 33 to 36. The circumferential seam
also exhibits a reinforcing groove 112, e.g. in the form of
an offset, as clearly evident in the circled detail, which
contributes to the sealing and reinforcing of the opening
tab or beverage can closure element.
Figures 41 to 44 are similar to Figures 37 to 40, but also
illustrate a detail of a variant with an extended lug 124 to
enable better fixing of the opening tab or beverage can
closure element during locking. This extended lug 124 is
illustrated as a round projection, but it can have any other
shape, including rectangular, triangular, etc., and one or
more extended lugs can be provided. Figures 41 to 44
illustrate the extended lug 124 in combination with the
offset illustrated in Figures 37 to 40, but it can also be
used in conjunction with the circumferential rim without an
offset(see Figures 33 to 36).
Figures 45 to 47 illustrate an alternative option for
locking the dispensing opening. The upwardly curving surface
CA 02795237 2012-10-02
61/100 -
is pressed downwards into the dispensing opening and extends
practically horizontally or is only slightly curved
downwards. This is achieved because the circumferential rim
of the opening tab or beverage can closure element 10 is
only slightly smaller than the dispensing opening (i.e. that
the circumferential rim and dispensing opening are so
coordinated that a clamping effect of this kind is achieved
in the horizontal position or the slightly downwards
curvature which prevents a complete downwards curvature). An
adequate lock is achieved through this clamping effect. Fig.
46 illustrates the position where the opening tab or
beverage can closure element is in the dispensing opening,
but not yet locked. Fig. 47 illustrates the locked position
based on the clamping effect, whereby the opening tab or
beverage can closure element 10 is in the horizontal
position. The offset and/or the extended lug 121 can also be
used in the case of this embodiment according to Figures 45
to 47 and all other embodiments.
Figures 48 to 50 illustrate an embodiment corresponding to
the embodiment in Figures 45 to 47 whereby additional
reinforcing grooves 126 are provided.
Figures 51 to 53 illustrate an embodiment corresponding to
the embodiment in Figures 45 to 47 whereby additional
reinforcing ribs 127 are provided.
Figures 54 to 57 illustrate a further option for locking the
dispensing opening. The opening tab or beverage can closure
element 10 in this embodiment has an upwardly curving
surface and a downwardly curving surface 128 configured in
the middle (this surface can also be configured outside the
middle). The opening tab or beverage can closure element is
therefore an undulated form. Locking in this embodiment also
consists of the opening tab or beverage can closure element
being pressed downwards, but it functions here in that the
undulated form reverses when it is pressed downwards (i.e.
CA 02795237 2012-10-02
- 62/100 -
the upwardly curving surface curves downwards and the
downwardly curving surface configured in the middle 128
curves upwards, as evident in Figure 57. Reopening can be
achieved here by pressing on the upwardly curving surface
128 (Figure 57).
Figures 58 to 59 illustrate a variant as compared to the
embodiment in Figures 54 to 57, whereby one or more
encompassing lugs or a completely or only partially
circumferential rim encompasses the dispensing opening when
the rim is pressed in. The one or more encompassing lugs or
completely or only partially circumferential rim are
assigned the reference number 163 in Figures 58 and 59. This
lock is a type of snap-in effect, whereby a clamping effect
can occur under certain circumstances.
Figures 60 and 61 and Figures 62 and 63 illustrate a similar
locking mechanism as in Figures 58 and 59. Figures 60 and 61
illustrate a downwardly curving surface, which reverses
completely during locking. In contrast to this, Figures 62
and 63 illustrate that the upwardly curving surface
partially contains a horizontal surface 1210 (the horizontal
surface can be as large or small as desired), whereby the
opening tab or beverage can closure element does not extend
as far downwards in the locked position.
Figure 64 illustrates further variants with different lug
shapes when compared to the lug shapes illustrated in
Figures 33 to 53.
Figures 65 to 71 illustrate that different shapes of
dispensing openings can be combined with different shapes of
the curved surface of the opening tab or beverage can
closure element. The dashed line in Figures 65 to 71
illustrates a possible dispensing opening in the lid.
Figures 69 and 71 additionally illustrate a cross section of
the unlocked and locked position respectively. Figures 72 to
CA 02795237 2012-10-02
- 63/100 -
75 illustrate the corresponding cross section shape options;
Figure 73 illustrates the locked state. Figure 74 a)
illustrates a continuous rim, whereas the remaining cross
section shapes in Figures 74 b) to 74 e) exhibit a fluted or
stamped out rim.
Figures 76 to 81 illustrate section and plan views of
further variants as compared to those illustrated in Figures
65 to 75.
Figures 82 to 84 illustrate how the rivet 14, which acts as
the fixing and pivoting axis for the opening tab or beverage
can closure element is stamped out of the lid material. Part
of the lid material is shaped and then pressed downwards,
thus creating the rivet 14.
Figures 85 to 91 illustrate further cross section shapes, in
part also in the locked state.
Figures 92 to 100 illustrate section and plan views of
further variants further variants as compared to those
illustrated in Figures 76 to 81. These figures illustrate
both the unlocked and locked state in this respect.
Finally, Figures 101 to 102 illustrate further variants of
the embodiment of the opening tab or beverage can closure
element, whereby the shapes illustrated in Figure 102 can be
practically combined with the cross sections illustrated in
Figure 101 as desired.
Figures 103 to 107 illustrate an embodiment of a beverage can
lid 20 according to the invention, in which the beverage can
closure element 10 exhibits beadings and/or spreader lugs 171
and the beverage can lid 20 a groove and/or depression 172
for the inclusion of beadings and/or spreader lugs 171 when
stacking the beverage can lid 20 before manufacturing the
beverage cans. The groove and/or depression 172 should be
embodied at least in the area of the beadings and/or spreader
CA 02795237 2012-10-02
- 64/100 -
lugs 171 of the beverage can closure element 10, but it can
also be embodied in a continuous form and/or wider than the
beading and/or spreader lug 171 to be received. The advantage
of this embodiment of the invention is a space-saving
stackability of the beverage can lids, as can be seen
especially in Fig. 107. The beverage can lids can here be
stacked in the same or alternating orientation and/or in any
orientation to one another.
Figures 108 to 114 illustrate an embodiment of the beverage
can lid 20 according to the invention, in which a bubble 173
is provided in the beverage can lid, arranged below the
beverage can closure element in order to fix and support it
in its position in such a way that distorting or pushing-
through, as will be required when reclosing the beverage can,
will be prevented with the unopened beverage can. As shown in
Fig. 110 in particular, a stackability of the beverage can
lid is guaranteed.
As illustrated in the embodiment shown in Figures 115 to
116, the groove and/or depression 172 shown in the
embodiment of figures 103 to 107 can be provided in the
embodiment according to figures 108 to 114 to permit a
flatter stackability.
Figures 117 to 118 illustrate an embodiment of a beverage
can lid 20 according to the invention in which the bubble
173 exhibits a marking, such that the consumer realizes that
the beverage can is not unopened, but reclosed, as the
marking is visible. The marking can be a coloured marking,
for example in red. In the unopened condition of the
beverage can, corresponding to the illustration in Figures
115 to 116, the marking is covered by the beverage can
closure element 10 and thus not visible. For reclosing the
beverage can the beverage can closure element will be turned
away from bubble 173 over the opening, thus making bubble
173 and also the marking visible, as shown in Figures 117 to
CA 02795237 2012-10-02
- 65/100 -
118.
Figures 119 to 121 illustrate an embodiment of the beverage
can lid 20 according to the invention, in which depressions
175 in the beverage can lid 20 are provided for including
beadings and/or spreader lugs embodied in the beverage can
closure element 10, i.e. in other words, the depressions 175
form an interrupted or continuous groove for including the
beadings and/or spreader lugs.
Figures 122 to 124 illustrate an embodiment of a beverage
can lid 20 according to the invention, in which the bubble
176 exhibits a recess 174, in which the leverage section 131
of extension 13 of the beverage can closure element 10 can
be arranged, without hindering the movement of the beverage
can closure element 10 from the position of the unopened
beverage can (Fig. 123), i.e. a position in which the cover
element 12 is arranged over the bubble 176, to a position
for reclosing the beverage can (Fig. 124), i.e. a position
in which the cover element 12 is arranged over the opening
of the beverage can.
Figures 125 to 127 show an embodiment of the beverage can
lid 20 according to the invention in which a pre-impression
26 and/or curvature 26 is included in the beverage can lid
20. As illustrated in Fig. 125, the curvature of the
beverage can lid 20 is negative before filling, i.e. the
beverage can lid is curved inwardly. After filling under
pressure the beverage can lid, as illustrated in Fig. 126,
is curved outwardly. After opening the pressure drops and
the beverage can lid returns to the flat shape without a
curvature, as shown in Fig. 127.
Figures 128 to 130 show an embodiment of a beverage can lid
20 according to the invention in which the curvature 27 is
only embodied in the area shown on the left side in Figures
128 to 130.
CA 02795237 2012-10-02

An advantage and goal of the invention embodiments last
named is that the area of the beverage can lid, in which the
cover element 12 for reclosing the beverage can is to be
arranged, is level.
Figures 131 to 133 illustrate an embodiment of the beverage
can closure element 10 according to the invention in which a
seal 177 for sealing the beverage can when reclosing it
(Fig. 133) is included.
The seal 177 (preferably made of rubber, plastic e.g. PE)
can be fitted separately in a certain area in any way on the
bottom side of the beverage can closure element (the tab).
In the embodiment of the invention shown in Figures 134 to
136 the seal 178 can also be fitted on the complete bottom
side of the beverage can ?? tab ?? in any way. Here for
sealing additionally fitted sealing lips in any embodiment
can achieve a better tightness.
As shown in Fig. 136 the opening will be sealed by pressing
on (by bracing) the seal 178.
As shown by means of the embodiments of the invention
illustrated in Figures 137 to 139, the seal 181 and/or 183
and/or the sealing layer (any material used for similar
seals, e.g. silicone, PE or other materials with food
authorization) can be provided on the entire surface (Fig.
138, seal 181) or only on a partial surface (Fig. 139, seal
183) on the bottom side of the beverage can closure element
(the tab), whereby the embodiments can be configured with
or without lug 182 and/or 184.
In the embodiment illustrated in Figures 140 to 141 the seal
185 and/or sealing layer is shown as a hatched area. The
curved cover element 12 is configured without a seal on its
CA 02795237 2012-10-02
67/100 -
bottom side. The sealing layer (any sealing material) can
also cover only certain areas of the bottom side of the
beverage can closure element 10 (the tab). As all
embodiments, the embodiment can be configured with or
without lugs 186.
As shown in the embodiment illustrated in Figures 142 to
143, the beverage can closure element 10 can exhibit a
reinforcement profile 188, under which the seal and/or
sealing band 187 (shown as hatched area) is arranged along
the predetermined rupture line 22 and outside the opening
section 23. Here Fig. 143 illustrates the cross section and
an enlarged detailed view in the area of the circle. This
embodiment exhibits lugs/spreader lugs, as shown in the
overall cross section.
According to the embodiment of the invention illustrated in
Figures 144 to 147 depressions or pinches can be configured
in the beverage can closure element according to the
invention for a better buckling in the material (e.g. sheet
metal, preferably made of aluminium). These can have
continuous or interrupted shapes. These buckling lines 191
and/or pinches permit an easier movement (similar to a
hinge) of the partial areas. This is especially advantageous
when reclosing the beverage can, when the beverage can
closure element has to buckle and/or move around the
buckling line 191.
Fig. 147 illustrates a possible embodiment of the cross
section of the buckling line 191. Of course, also other
shapes can be provided. For example, the pinch and/or recess
can be embodied only on the top side or the bottom side.
The embodiment illustrated in Figures 144 to 147 embodies
lugs 190. The expert clearly knows that another shape or
number of lugs 190 can also be provided. Alternatively, the
lugs 190 can also be omitted.

Figures 148 to 149 illustrate a further embodiment of a
beverage can closure element according to the invention, in
which the beverage can closure element is embodied of mixed
materials, such as plastic/metal or metal/plastic. In the
embodiment shown the metal part (dotted line) is embedded in
the plastic (e.g. by injection moulding). In the embodiment
shown with a plastic coating 193 the lugs 192 can be
embodied in a continuous and/or interrupted way and/or
consist of solid material. These and all other and/or
further embodiments can exhibit the seals described in the
present application or other seals known to the expert or
obviously reasonable seals.
Figures 150 to 151 illustrate a further embodiment of a
beverage can closure element according to the invention,
embodied of plastic. Here the lugs 194 can be embodied in a
continuous and/or interrupted form and/or consist of solid
material.
Figures 152 to 153 illustrates a further embodiment of a
beverage can closure element according to the invention, in
which the beverage can closure element 10 exhibits a bimetal
area 196. The bimetal area can make up only the area of the
beverage can closure element, arranged over the bubble
embodied in the beverage can lid, or also the whole surface
on the bottom or top side of the beverage can closure
element. Due to temperature differences a snapping effect
can be created upon heating or cooling. The bimetal can be
fitted to the bottom or to the top side of the "bubble"
depending on the requirement of the reaction.
Figures 154 to 155 illustrate a further embodiment of a
beverage can closure element according to the invention in
which the beverage can closure element 10 exhibits a
reinforcement at its rim. The beverage can closure element
can exhibit reinforcements of any shape, such that even
CA 02795237 2012-10-02
69/100 -
thinner metal sheets can be used, for example. In Fig. 154
the curved reinforcements 197 are illustrated as hatched
areas in the top view, whereby the cross section is
illustrated in Fig. 155.
Figures 156 to 163 illustrate variations of the
reinforcements 199; 200; 201 and/or 203. The reinforcements
can exhibit any desired suitable shape, thus also thinner
sheet metals can be used.
In the embodiment of Figures 156 to 157 curved
reinforcements 199 are provided, illustrated as hatched
areas in the top view.
Figures 158 to 159 illustrate a further embodiment of a
beverage can closure element according to the invention, in
which a lug 400 is provided at the end of the extension 13,
to facilitate the first opening of the beverage can. Lug 400
at the end of the extension 13 can be embodied in continuous
and/or interrupted form or only along a short course.
Figures 160 to 163 illustrate further embodiments of a
beverage can closure element 10 according to the invention,
whereby variations of rim reinforcements are illustrated.
According to the embodiment of the invention shown in
Figures 160 and 161 the reinforcements 203 can be embodied
in a tubular shape, for example with a tube bent downward.
The embodiment example shown in Figures 162 and 163 differs
from that shown in figures 160 and 161 in that the
reinforcements 203 are bent upward. The lugs 204 are
comparable to the lugs 202 of the embodiment in Figures 160
to 161.
Figures 164 to 165 illustrate a further embodiment of a
beverage can lid 20 according to the invention in which
ball-shaped leverage points are provided, for example. The
leverage points 401 can be embodied in a conical shape
CA 02795237 2012-10-02
- 70/100 -
and/or continuously. The leverage points can exhibit any
suitable shape, i.e. the leverage points can be embodied
round and/or and have any suitable shape, any suitable
position etc. Leverage points can also be embodied in the
beverage can closure element to ensure an easier opening by
the opening lever. These opening leverage points are each
hidden in the stamped-in depressions of the lid and will
take action only after opening and turning the beverage can
closure element. The leverage points/areas relieve the
curvature and can be fitted at any point at the lid or tab.
Figures 166 to 168 illustrate a further embodiment of a
beverage can lid 20 according to the invention,
corresponding basically to that in Figures 164 to 165. In
this embodiment only two leverage points 404 are provided,
whereas the embodiment of Figures 164 to 165 embodies three
leverage points 401. In addition, the embodiment of Figures
164 to 165 is shown in the unopened position, whereas the
embodiment illustrated in Figures 166 to 168 shows the
reclosed condition of the beverage can.
By twisting the beverage can closure element 10 out of the
position shown in Fig. 165 into the position shown in Fig.
167, the leverage points 401 and 404 are activated. As shown
in the enlarged illustration of Fig. 165, also grooves
and/or depressions 402 and 405 can be included in the
beverage can lid. In the not yet activated position the
leverage points are arranged in the depressions 402 and 405.
By integrating depressions of any shape and size, the
tension on the "tip" of the dome can be reduced and the
construction height can be minimized. Such embodiments of
the beverage can closure element according to the invention
are illustrated in Figures 169 to 170 and/or 171 to 172, for
example.
CA 02795237 2012-10-02
71/100 -
In the embodiment illustrated in Figures 169 to 170 lugs 408
and a depression 407 are included, whereas the embodiment of
Figures 171 to 172 can include lugs 410 and a
circumferential groove 409 of any shape and size.
Figures 173 to 174 illustrate a further embodiment of a
beverage can lid 20 according to the invention in which the
curvature extends beyond the opening edge, resulting in a
"rising" of the rims. By adequate constructive elements of
the beverage can closure element the opening element will be
placed higher and the opening mechanism will provided.
The Figures 175 to 177 illustrate a further embodiment of a
beverage can lid 20 according to the invention in which the
undulations 412 and/or 413 are included in the beverage can
closure element 10 and the beverage can lid 20. In the
embodiment example illustrated, the undulations 412, 413 are
embodied as circumferential and/or continuous undulations.
It is clear that the undulations can be configured as
positive and/or negative curvature. The undulations create a
sealing of the reclosed beverage can if the lugs 411 grab
below the beverage can lid 20, as illustrated in Fig. 177.
In addition further sealing means can be included, as shown
in connection with other embodiments of this disclosure.
Figures 178 to 180 illustrate a further embodiment of a
beverage can closure element 10 according to the invention
in which a coating 414 of plastic and/or silicone and/or
rubber and/or another sealing material suitable for food
with a sealing bead 415 is embodied. In addition, according
to the invention, the beverage can closure element can be
embodied with or without coating 414 or on the full and/or
only partial surface.
The profiles and/or shapes of the seals illustrated in the
figures can be varied according to requirements. The basic
principle illustrated in Figures 178 to 180 of the sealing
bead 415 is the spreading and the closing of the drinking
CA 02795237 2012-10-02
72/100 -
opening, as shown in Fig. 180. The embodiment of the sealing
bead can here be ring-shaped, circumferential and/or
interrupted and/or as continuous surface on the level of the
bead height 414A, with/or without depressions or recesses.
The ring shape of the sealing bead 415 can and should here
be adapted to the opening, i.e. it does not have to be
circular, but it is rather configured as illustrated in Fig.
178. The coatings 414 and the sealing bead 415 are shown as
hatched areas in Fig. 178.
The shape and/or the cross section of the sealing ring
and/or sealing bead 415 can be embodied in different ways.
The embodiment of the sealing ring/sealing bead 415 can be
continuous or preferably interrupted.
The upper material of the beverage can closure element 10
can consist of a metal and/or preferably of an aluminium
alloy. The coating 414 and/or the sealing bead (e.g. a
moulded part) can be embodied of plastic/silicone/rubber
and/or another sealing material suitable for food (see
hatched area).
Figures 181 to 183 illustrate a further embodiment of a
beverage can closure element 10 according to the invention,
corresponding to the embodiment shown in Figures 178 to 180,
only the sealing ring and/or sealing bead and/or sealing lip
417 is embodied differently. The sealing lip 417 of the
embodiment shown in Figures 181 to 183 is rather shaped like
a lip and/or a barbed hook in the cross section (see Figures
182 and/or 183), whereas the sealing bead 415 of the
embodiment shown in Figures 178 to 180 is embodied as a
circular, drused and/or rectangular shape in the cross
section (see Figures 179 and/or 180).
Figures 184 to 188 illustrate a further embodiment of a
beverage can lid 20 according to the invention, in which the
predetermined rupture line 22 does not completely surround
the opening section 23, such that a ligament 418 remains
CA 02795237 2012-10-02
- 73/100 -
when opening it which still connects the opening section 23
with the beverage can lid, as illustrated in Fig. 185. The
seal is embodied as spreader ring 419 with knobs and/ or
lugs 420.
As illustrated in particular in Fig. 188 and Fig. 186, the
beverage can closure element 10 exhibits a wide knob and/or
wide lug 421 which serves for sealing in the area of the
ligament 418.
As in case of the other embodiments the seal can be embodied
as coating and/or molded part, embodied of plastic and/or
silicone and/or rubber and/or another suitable sealing
material (see hatched area in the Figures 186 to 188). It is
also conceivable, for example, that the seal is embodied of
the material of the beverage can closure element, whereby
the required elasticity can also be provided by the material
shape. The material can include a metal, an alloy or
plastic, for example.
The embodiment is illustrated with lugs and/or knobs 420,
421 which can exhibit any suitable shape. As mentioned
above, the lugs and/or knobs can also be configured smaller
or can be deleted, if a sufficient sealing is achieved by
the embodiment of the beverage can closure element 10 and
the beverage can lid 20.
By separating the circumferential spreader ring 420, an
easier operation in case of harder materials (PE and/or
rubber and/or plastic and/or metal etc.) is ensured.
In the area of the opening, where the remaining material
(opening section) is attached to the beverage can lid as
tongue, so to speak, i.e. in the section of the ligament
418, an extra-longer sealing lug and/or knob 421 which is
configured according to the ligament 418 can be embodied.
This concerns the width and height of the lug. This seal can
CA 02795237 2012-10-02
74/100 -
be embodied of any suitable material (also as metal lug
which can be deep-drawn, for example).
Figures 189 to 194 illustrate the reclosing and re-opening
of a beverage can, taking as an example a beverage can lid
20 according to an embodiment of the invention, whereby the
beverage can closure element 10 exhibits spreader lugs 422
and a circumferential groove 423 in the center.
By pressing on the area within the groove 423 (Fig. 191) the
beverage can closure element is moved from the open position
(Fig. 189) to the closed and/or sealed position (Fig. 191).
By pressing again on the area within the groove 423 (Fig.
193) the beverage can closure element is moved from the
closed and/or sealed position (Fig. 192) to the open
position (Fig. 194), in which the beverage can closure
element can again be arranged outside the opening, e.g. over
the bubble (not illustrated here, but shown in other
embodiments of the invention), to permit drinking and/or
pouring from the opening. Here the beverage can closure
element is preferably embodied such that after operation
(Fig. 193) it moves independently to the open position of
Fig. 194 due to the spring effect.
Figures 195 to 196 illustrate a further embodiment of a
beverage can closure element 10 according to the invention
in which recesses and/or cut-outs 424 are included. The cut-
out area 425 is embodied downward from the beverage can
closure element projecting in the direction of the beverage
can such that it supports itself on the rim of the opening
in the beverage can lid 20 when reclosing the beverage can.
In embodiments of the beverage can closure element 10 of
sheet metal and/or metal thus a sheet metal part 425 and/or
metal part protrudes downwards.
The cut-outs 424 can be planned in any suitable shape,
number and dimension. Illustrated is an embodiment with four

cut-outs 425.
At the beverage can closure element 10 any suitable seal can
be arranged, as is described in the present disclosure in
context with other embodiments of the invention.
The different special embodiments of the invention disclosed
here can also be combined with each other in any suitable
way. In particular, the disclosed seals can be combined in a
suitable way with the other features regarding the shaping
of the beverage can lid 10 and/or the beverage can closure
element 20.
Figures 103 to 107 illustrate an embodiment of a beverage can
lid 20 according to the invention, in which the beverage can
closure element 10 exhibits beadings and/or spreader lugs 171
and the beverage can lid 20 a groove and/or depression 172
for the inclusion of beadings and/or spreader lugs 171 when
stacking the beverage can lid 20 before manufacturing the
beverage cans. The groove and/or depression 172 should be
embodied at least in the area of the beadings and/or spreader
lugs 171 of the beverage can closure element 10, but it can
also be embodied in a continuous form and/or wider than the
beading and/or spreader lug 171 to be received. The advantage
of this embodiment of the invention is a space-saving
stackability of the beverage can lids, as can be seen
especially in Fig. 107. The beverage can lids can here be
stacked in the same or alternating orientation and/or in any
orientation to one another.
Figures 108 to 114 illustrate an embodiment of the beverage
can lid 20 according to the invention, in which a bubble 173
is provided in the beverage can lid, arranged below the
beverage can closure element in order to fix and support it
in its position in such a way that distorting or pushing-
through, as will be required when reclosing the beverage can,
will be prevented with the unopened beverage can. As shown in
CA 02795237 2012-10-02
76/100 -
Fig. 110 in particular, a stackability of the beverage can
lid is guaranteed.
As illustrated in the embodiment shown in Figures 115 to
116, the groove and/or depression 172 shown in the
embodiment of figures 103 to 107 can be provided in the
embodiment according to figures 108 to 114 to permit a
flatter stackability.
Figures 117 to 118 illustrate an embodiment of a beverage
can lid 20 according to the invention in which the bubble
173 exhibits a marking, such that the consumer realizes that
the beverage can is not unopened, but reclosed, as the
marking is visible. The marking can be a coloured marking,
for example in red. In the unopened condition of the
beverage can, corresponding to the illustration in Figures
115 to 116, the marking is covered by the beverage can
closure element 10 and thus not visible. For reclosing the
beverage can the beverage can closure element will be turned
away from bubble 173 over the opening, thus making bubble
173 and also the marking visible, as shown in Figures 117 to
118.
Figures 119 to 121 illustrate an embodiment of the beverage
can lid 20 according to the invention, in which depressions
175 in the beverage can lid 20 are provided for including
beadings and/or spreader lugs embodied in the beverage can
closure element 10, i.e. in other words, the depressions 175
form an interrupted or continuous groove for including the
beadings and/or spreader lugs.
Figures 122 to 124 illustrate an embodiment of a beverage
can lid 20 according to the invention, in which the bubble
176 exhibits a recess 174, in which the leverage section 131
of extension 13 of the beverage can closure element 10 can
be arranged, without hindering the movement of the beverage
can closure element 10 from the position of the unopened
CA 02795237 2012-10-02
77/100 -
beverage can (Fig. 123), i.e. a position in which the cover
element 12 is arranged over the bubble 176, to a position
for reclosing the beverage can (Fig. 124), i.e. a position
in which the cover element 12 is arranged over the opening
of the beverage can.
Figures 125 to 127 show an embodiment of the beverage can
lid 20 according to the invention in which a pre-impression
26 and/or curvature 26 is included in the beverage can lid
20. As illustrated in Fig. 125, the curvature of the
beverage can lid 20 is negative before filling, i.e. the
beverage can lid is curved inwardly. After filling under
pressure the beverage can lid, as illustrated in Fig. 126,
is curved outwardly. After opening the pressure drops and
the beverage can lid returns to the flat shape without a
curvature, as shown in Fig. 127.
Figures 128 to 130 show an embodiment of a beverage can lid
20 according to the invention in which the curvature 27 is
only embodied in the area shown on the left side in Figures
128 to 130.
An advantage and goal of the invention embodiments last
named is that the area of the beverage can lid, in which the
cover element 12 for reclosing the beverage can is to be
arranged, is level.
Figures 131 to 133 illustrate an embodiment of the beverage
can closure element 10 according to the invention in which a
seal 177 for sealing the beverage can when reclosing it
(Fig. 133) is included.
The seal 177 (preferably made of rubber, plastic e.g. PE)
can be fitted separately in a certain area in any way on the
bottom side of the beverage can closure element (the tab).
In the embodiment of the invention shown in Figures 134 to
CA 02795237 2012-10-02
- 78/100 -
136 the seal 178 can also be fitted on the complete bottom
side of the beverage can ?? tab ?? in any way. Here for
sealing additionally fitted sealing lips in any embodiment
can achieve a better tightness.
As shown in Fig. 136 the opening will be sealed by pressing
on (by bracing) the seal 178.
As shown by means of the embodiments of the invention
illustrated in Figures 137 to 139, the seal 181 and/or 183
and/or the sealing layer (any material used for similar
seals, e.g. silicone, PE or other materials with food
authorization) can be provided on the entire surface (Fig.
138, seal 181) or only on a partial surface (Fig. 139, seal
183) on the bottom side of the beverage can closure element
(the tab), whereby the embodiments can be configured with
or without lug 182 and/or 184.
In the embodiment illustrated in Figures 140 to 141 the seal
185 and/or sealing layer is shown as a hatched area. The
curved cover element 12 is configured without a seal on its
bottom side. The sealing layer (any sealing material) can
also cover only certain areas of the bottom side of the
beverage can closure element 10 (the tab). As all
embodiments, the embodiment can be configured with or
without lugs 186.
As shown in the embodiment illustrated in Figures 142 to
143, the beverage can closure element 10 can exhibit a
reinforcement profile 188, under which the seal and/or
sealing band 187 (shown as hatched area) is arranged along
the predetermined rupture line 22 and outside the opening
section 23. Here Fig. 143 illustrates the cross section and
an enlarged detailed view in the area of the circle. This
embodiment exhibits lugs/spreader lugs, as shown in the
overall cross section.
CA 02795237 2012-10-02
- 79/100 -
According to the embodiment of the invention illustrated in
Figures 144 to 147 depressions or pinches can be configured
in the beverage can closure element according to the
invention for a better buckling in the material (e.g. sheet
metal, preferably made of aluminium). These can have
continuous or interrupted shapes. These buckling lines 191
and/or pinches permit an easier movement (similar to a
hinge) of the partial areas. This is especially advantageous
when reclosing the beverage can, when the beverage can
closure element has to buckle and/or move around the
buckling line 191.
Fig. 147 illustrates a possible embodiment of the cross
section of the buckling line 191. Of course, also other
shapes can be provided. For example, the pinch and/or recess
can be embodied only on the top side or the bottom side.
The embodiment illustrated in Figures 144 to 147 embodies
lugs 190. The expert clearly knows that another shape or
number of lugs 190 can also be provided. Alternatively, the
lugs 190 can also be omitted.
Figures 148 to 149 illustrate a further embodiment of a
beverage can closure element according to the invention, in
which the beverage can closure element is embodied of mixed
materials, such as plastic/metal or metal/plastic. In the
embodiment shown the metal part (dotted line) is embedded in
the plastic (e.g. by injection moulding). In the embodiment
shown with a plastic coating 193 the lugs 192 can be
embodied in a continuous and/or interrupted way and/or
consist of solid material. These and all other and/or
further embodiments can exhibit the seals described in the
present application or other seals known to the expert or
obviously reasonable seals.
Figures 150 to 151 illustrate a further embodiment of a
beverage can closure element according to the invention,
CA 02795237 2012-10-02
80/100 -
embodied of plastic. Here the lugs 194 can be embodied in a
continuous and/or interrupted form and/or consist of solid
material.
Figures 152 to 153 illustrates a further embodiment of a
beverage can closure element according to the invention, in
which the beverage can closure element 10 exhibits a bimetal
area 196. The bimetal area can make up only the area of the
beverage can closure element, arranged over the bubble
embodied in the beverage can lid, or also the whole surface
on the bottom or top side of the beverage can closure
element. Due to temperature differences a snapping effect
can be created upon heating or cooling. The bimetal can be
fitted to the bottom or to the top side of the "bubble"
depending on the requirement of the reaction.
Figures 154 to 155 illustrate a further embodiment of a
beverage can closure element according to the invention in
which the beverage can closure element 10 exhibits a
reinforcement at its rim. The beverage can closure element
can exhibit reinforcements of any shape, such that even
thinner metal sheets can be used, for example. In Fig. 154
the curved reinforcements 197 are illustrated as hatched
areas in the top view, whereby the cross section is
illustrated in Fig. 155.
Figures 156 to 163 illustrate variations of the
reinforcements 199; 200; 201 and/or 203. The reinforcements
can exhibit any desired suitable shape, thus also thinner
sheet metals can be used.
In the embodiment of Figures 156 to 157 curved
reinforcements 199 are provided, illustrated as hatched
areas in the top view.
Figures 158 to 159 illustrate a further embodiment of a
beverage can closure element according to the invention, in
which a lug 400 is provided at the end of the extension 13,
CA 02795237 2012-10-02
81/100 -
to facilitate the first opening of the beverage can. Lug 400
at the end of the extension 13 can be embodied in continuous
and/or interrupted form or only along a short course.
Figures 160 to 163 illustrate further embodiments of a
beverage can closure element 10 according to the invention,
whereby variations of rim reinforcements are illustrated.
According to the embodiment of the invention shown in
Figures 160 and 161 the reinforcements 203 can be embodied
in a tubular shape, for example with a tube bent downward.
The embodiment example shown in Figures 162 and 163 differs
from that shown in figures 160 and 161 in that the
reinforcements 203 are bent upward. The lugs 204 are
comparable to the lugs 202 of the embodiment in Figures 160
to 161.
Figures 164 to 165 illustrate a further embodiment of a
beverage can lid 20 according to the invention in which
ball-shaped leverage points are provided, for example. The
leverage points 401 can be embodied in a conical shape
and/or continuously. The leverage points can exhibit any
suitable shape, i.e. the leverage points can be embodied
round and/or and have any suitable shape, any suitable
position etc. Leverage points can also be embodied in the
beverage can closure element to ensure an easier opening by
the opening lever. These opening leverage points are each
hidden in the stamped-in depressions of the lid and will
take action only after opening and turning the beverage can
closure element. The leverage points/areas relieve the
curvature and can be fitted at any point at the lid or tab.
Figures 166 to 168 illustrate a further embodiment of a
beverage can lid 20 according to the invention,
corresponding basically to that in Figures 164 to 165. In
this embodiment only two leverage points 404 are provided,
CA 02795237 2012-10-02
82/100 -
whereas the embodiment of Figures 164 to 165 embodies three
leverage points 401. In addition, the embodiment of Figures
164 to 165 is shown in the unopened position, whereas the
embodiment illustrated in Figures 166 to 168 shows the
reclosed condition of the beverage can.
By twisting the beverage can closure element 10 out of the
position shown in Fig. 165 into the position shown in Fig.
167, the leverage points 401 and 404 are activated. As shown
in the enlarged illustration of Fig. 165, also grooves
and/or depressions 402 and 405 can be included in the
beverage can lid. In the not yet activated position the
leverage points are arranged in the depressions 402 and 405.
By integrating depressions of any shape and size, the
tension on the "tip" of the dome can be reduced and the
construction height can be minimized. Such embodiments of
the beverage can closure element according to the invention
are illustrated in Figures 169 to 170 and/or 171 to 172, for
example.
In the embodiment illustrated in Figures 169 to 170 lugs 408
and a depression 407 are included, whereas the embodiment of
Figures 171 to 172 can include lugs 410 and a
circumferential groove 409 of any shape and size.
Figures 173 to 174 illustrate a further embodiment of a
beverage can lid 20 according to the invention in which the
curvature extends beyond the opening edge, resulting in a
"rising" of the rims. By adequate constructive elements of
the beverage can closure element the opening element will be
placed higher and the opening mechanism will provided.
The Figures 175 to 177 illustrate a further embodiment of a
beverage can lid 20 according to the invention in which the
undulations 412 and/or 413 are included in the beverage can
closure element 10 and the beverage can lid 20. In the
embodiment example illustrated, the undulations 412, 413 are
CA 02795237 2012-10-02
83/100 -
embodied as circumferential and/or continuous undulations.
It is clear that the undulations can be configured as
positive and/or negative curvature. The undulations create a
sealing of the reclosed beverage can if the lugs 411 grab
below the beverage can lid 20, as illustrated in Fig. 177.
In addition further sealing means can be included, as shown
in connection with other embodiments of this disclosure.
Figures 178 to 180 illustrate a further embodiment of a
beverage can closure element 10 according to the invention
in which a coating 414 of plastic and/or silicone and/or
rubber and/or another sealing material suitable for food
with a sealing bead 415 is embodied. In addition, according
to the invention, the beverage can closure element can be
embodied with or without coating 414 or on the full and/or
only partial surface.
The profiles and/or shapes of the seals illustrated in the
figures can be varied according to requirements. The basic
principle illustrated in Figures 178 to 180 of the sealing
bead 415 is the spreading and the closing of the drinking
opening, as shown in Fig. 180. The embodiment of the sealing
bead can here be ring-shaped, circumferential and/or
interrupted and/or as continuous surface on the level of the
bead height 414A, with/or without depressions or recesses.
The ring shape of the sealing bead 415 can and should here
be adapted to the opening, i.e. it does not have to be
circular, but it is rather configured as illustrated in Fig.
178. The coatings 414 and the sealing bead 415 are shown as
hatched areas in Fig. 178.
The shape and/or the cross section of the sealing ring
and/or sealing bead 415 can be embodied in different ways.
The embodiment of the sealing ring/sealing bead 415 can be
continuous or preferably interrupted.
The upper material of the beverage can closure element 10
can consist of a metal and/or preferably of an aluminium
CA 02795237 2012-10-02
- 84/100 -
alloy. The coating 414 and/or the sealing bead (e.g. a
moulded part) can be embodied of plastic/silicone/rubber
and/or another sealing material suitable for food (see
hatched area).
Figures 181 to 183 illustrate a further embodiment of a
beverage can closure element 10 according to the invention,
corresponding to the embodiment shown in Figures 178 to 180,
only the sealing ring and/or sealing bead and/or sealing lip
417 is embodied differently. The sealing lip 417 of the
embodiment shown in Figures 181 to 183 is rather shaped like
a lip and/or a barbed hook in the cross section (see Figures
182 and/or 183), whereas the sealing bead 415 of the
embodiment shown in Figures 178 to 180 is embodied as a
circular, drused and/or rectangular shape in the cross
section (see Figures 179 and/or 180).
Figures 184 to 188 illustrate a further embodiment of a
beverage can lid 20 according to the invention, in which the
predetermined rupture line 22 does not completely surround
the opening section 23, such that a ligament 418 remains
when opening it which still connects the opening section 23
with the beverage can lid, as illustrated in Fig. 185. The
seal is embodied as spreader ring 419 with knobs and/ or
lugs 420.
As illustrated in particular in Fig. 188 and Fig. 186, the
beverage can closure element 10 exhibits a wide knob and/or
wide lug 421 which serves for sealing in the area of the
ligament 418.
As in case of the other embodiments the seal can be embodied
as coating and/or molded part, embodied of plastic and/or
silicone and/or rubber and/or another suitable sealing
material (see hatched area in the Figures 186 to 188). It is
also conceivable, for example, that the seal is embodied of
the material of the beverage can closure element, whereby
CA 02795237 2012-10-02
85/100 -
the required elasticity can also be provided by the material
shape. The material can include a metal, an alloy or
plastic, for example.
The embodiment is illustrated with lugs and/or knobs 420,
421 which can exhibit any suitable shape. As mentioned
above, the lugs and/or knobs can also be configured smaller
or can be deleted, if a sufficient sealing is achieved by
the embodiment of the beverage can closure element 10 and
the beverage can lid 20.
By separating the circumferential spreader ring 420, an
easier operation in case of harder materials (PE and/or
rubber and/or plastic and/or metal etc.) is ensured.
In the area of the opening, where the remaining material
(opening section) is attached to the beverage can lid as
tongue, so to speak, i.e. in the section of the ligament
418, an extra-longer sealing lug and/or knob 421 which is
configured according to the ligament 418 can be embodied.
This concerns the width and height of the lug. This seal can
be embodied of any suitable material (also as metal lug
which can be deep-drawn, for example).
Figures 189 to 194 illustrate the reclosing and re-opening
of a beverage can, taking as an example a beverage can lid
20 according to an embodiment of the invention, whereby the
beverage can closure element 10 exhibits spreader lugs 422
and a circumferential groove 423 in the center.
By pressing on the area within the groove 423 (Fig. 191) the
beverage can closure element is moved from the open position
(Fig. 189) to the closed and/or sealed position (Fig. 191).
By pressing again on the area within the groove 423 (Fig.
193) the beverage can closure element is moved from the
closed and/or sealed position (Fig. 192) to the open
position (Fig. 194), in which the beverage can closure
CA 02795237 2012-10-02
86/100 -
element can again be arranged outside the opening, e.g. over
the bubble (not illustrated here, but shown in other
embodiments of the invention), to permit drinking and/or
pouring from the opening. Here the beverage can closure
element is preferably embodied such that after operation
(Fig. 193) it moves independently to the open position of
Fig. 194 due to the spring effect.
Figures 195 to 196 illustrate a further embodiment of a
beverage can closure element 10 according to the invention
in which recesses and/or cut-outs 424 are included. The cut-
out area 425 is embodied downward from the beverage can
closure element projecting in the direction of the beverage
can such that it supports itself on the rim of the opening
in the beverage can lid 20 when reclosing the beverage can.
In embodiments of the beverage can closure element 10 of
sheet metal and/or metal thus a sheet metal part 425 and/or
metal part protrudes downwards.
The cut-outs 424 can be planned in any suitable shape,
number and dimension. Illustrated is an embodiment with four
cut-outs 425.
At the beverage can closure element 10 any suitable seal can
be arranged, as is described in the present disclosure in
context with other embodiments of the invention.
The different special embodiments of the invention disclosed
here can also be combined with each other in any suitable
way. In particular, the disclosed seals can be combined in a
suitable way with the other features regarding the shaping
of the beverage can lid 10 and/or the beverage can closure
element 20.
As already indicated above, the opening tab or beverage can
closure element 10 can be moved by 180 around the axis of
the rivet 14 to lock the dispensing opening, whereby the
CA 02795237 2012-10-02
87/100 -
opening tab or beverage can closure element 10 comes to rest
over the dispensing opening. It is automatically discernible
when the 180 position is reached, because the
circumferential rim or the projections provided instead of
the circumferential rim then sink into the dispensing
opening. In addition, one or more stops can be configured to
exactly define the 180 position. The stops can be
configured so that they define the 180 position in the case
of pivoting to the right and/or the left.
The dispensing opening is usually round, but it can also
have another shape, such as the shape implied with the
dashed line in Figures 65 to 67 or any other shape (e.g.
oval, trapezoidal with rounded corners, etc.).
All variants and embodiment examples can be combined and
varied with each other as desired.
The embodiment example illustrated in Figures 48 to 50
essentially corresponds to the embodiment example
illustrated in Figures 45 to 47. The locking mechanism in
this embodiment is configured as a straight circumferential
rim 162, which is clamped against the rim of the opening in
the beverage can lid 20 in the locked state. A frictional
clamping lock is therefore achieved. The reinforcing beading
126 is flush with the straight circumferential rim 162.
The embodiment example illustrated in Figures 51 to 53
essentially corresponds to the embodiment example
illustrated in Figures 48 to 50. Reinforcing ribs 127 are
provided instead of reinforcing beading in this embodiment.
Both reinforcing ribs and reinforcing grooves can, of
course, be included in an embodiment example. The locking
mechanism is also configured as a straight circumferential
rim 162, which is clamped against the rim of the opening in
the beverage can lid 20 in the locked state. A frictional
clamping lock is therefore achieved. The reinforcing ribs
CA 02795237 2012-10-02
88/100 -
127 are configured flush with the straight circumferential
rim 162.
Figures 54 to 57 correspond to Figures 33 to 36 depression
128
Figures 58 and 59 illustrate a further embodiment example of
a beverage can closure element 10 according to the
invention. A circumferential seam 163 or one or more
encompassing lugs with a shape corresponding to the
illustration are provided. A type of snap-in effect occurs
in this lock, whereby a clamping effect can occur under
certain circumstances. An indentation 129 is provided
approximately in the middle of the cover element 12 which
can reverse during locking, as illustrated in Fig. 59.
The embodiment example illustrated in Figures 60 and 61
differs from that in Figures 58 and 59 to the extent that
the cover element 12 of the beverage can closure element 10
exhibits an upwardly curving surface, which curves downwards
during locking.
The embodiment example illustrated in Figures 62 and 63
differs from the embodiment example illustrated in Figures
58 and 59 and in 60 and 61 to the extent that the cover
element 12 of the beverage can closure element 10 exhibits
an upwardly curving surface, which preferably exhibits an
essentially straight surface in the middle. The size of the
middle straight surface can be selected as desired. The
cover element in this embodiment does not extend as far
downwards in the direction of the beverage can contents in
the locked state.
The section in Fig. 75 applies for all variants in Figures
74 a) to e)
It is obvious that the specialist can find obvious
CA 02795237 2012-10-02
89/100 -
alternatives and equivalent solutions when studying the
documents, including those, which fall within the scope of
protection of this application.
For example, alternative configurations are conceivable. For
example,
the principle of the beverage can closure element according
to the invention can also be applied to other containers in
the food industry. For example, it is conceivable that
closure elements according to the invention could be used on
packaging for milk or fruit juice made of a composite
material. The embodiment of the closure element according to
the invention can, in this respect, be preferably made of a
plastic material which could preferably correspond to the
material out of which, for example, the dispensing opening
is manufactured.
All variants and embodiment examples can be combined and
varied with each other as desired.
