Description

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 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.

3 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.

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.

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 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 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 = - 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.

= - 9/100 -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 colour, by letters, numbers or signs. This embodiment of the 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.

= - 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.

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 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 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 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 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 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 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 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 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 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.

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 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.

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 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 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.

Figures 22 and 23 illustrate sections through the wings 19 illustrated in Figures 18 to 21.

Figure 28a and 28b illustrate a variant of the opening tab or beverage can closure element with drinking straw hole or holes.

Figures 29 to 32 illustrate a variant of the embodiment of the invention illustrated in Figures 7 to 10, whereby preferably the same material as that of the beverage can or a combination of different materials can be used.

Figures 33 to 61 illustrate further locking mechanism designs, which can be used as variants of the embodiments illustrated in Figures 7 to 10.

Fig. 64 illustrates further variants of different lug shapes 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 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 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 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 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 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 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.

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 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 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 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.

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 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 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 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.

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 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 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 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 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 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 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.

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 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 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.

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 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 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 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.

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 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 127 are configured flush with the straight circumferential rim 162.

Figures 54 to 57 correspond to Figures 33 to 36 depression 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 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.
