Description

Container lid and container

The invention relates to a container lid according to the preamble of patent claim 1 or 3 and to a container according to the preamble of patent claim 30 or 31.

Among other things, it is known a container lid (DE 296 16 133), which is intended for cans and especially for beverage cans and has a container opening which is closed by a closure flap in the original closed container. To open the container, this closure tab can be at least partially removed or in the

Containers are pressed in, using an opening or tear-off ring provided on the closure. The container lid is formed in two parts and consists of a first, to be attached to the container or can body lid element, which also has the closure tab or the container opening, and a second, on the outer surface or

Top of the lid provided rotatable lid member. Due to the two-part design, the container opening, once opened, can be closed again by turning the second cover element accordingly. It is essential here that the second cover element is designed in the form of a circular disk and is guided in a form-fitting manner on the circumference or edge of the first cover element.

The object of the invention is to further improve the container lid or to show an improved and novel container. To achieve this object, a container lid according to claim 1 or 3 and a container according to claim 30 or 31 are formed.

In the case of the container lid according to the invention, too, the second lid element is designed in the form of a circular disk and has a positive fit on the edge of the first Cover element guided so that it is secured against lifting off the first cover element. As a result, a tight seal is ensured, in particular even when the container is closed again with the second cover element, especially also in the case of carbonated drinks, for example soft drinks or beer.

A special feature of the container lid according to the innovation is that the positive connection between the first lid element and the periphery or edge of the second lid element is provided on an edge region of the lid base concentrically surrounding the central axis of the lid, with a radial distance from the preferably ring-like or as Conical ring formed lid edge of the cup-like lid, so that stacking or "nesting" in the container lid when processing in a container sealing machine in an optimal manner and also processing the container lid with the usual closing tools are possible.

In the case of the container lid according to the innovation, the first lid element is made, for example, from a metal sheet or else from a suitable plastic, for example PET. Metal sheets are suitable for the production of the second cover element; However, this second cover element is preferably made of plastic, so that there is the possibility of optimal shaping and formation, in particular also the formation of rounded edges, edges and openings. The use of plastic for at least one of the two cover elements also ensures that when the cover elements are rotated relative to one another, these cover elements are not scratched, thus achieving a visually appealing and also hygienic solution. The form-fitting guidance of the second cover element on its circumference on the first cover element is achieved in that the edge of the second cover element engages behind an annular catch on the first cover element concentrically surrounding the central axis, for example engaging in an annular groove on the first cover element, which (groove) Central axis concentrically surrounds and is open radially to the outside with respect to this central axis, or else engages with its circumference behind an annular projection on the first cover element, which in turn concentrically surrounds the central axis of the cover and in an axial direction radially to this central axis via adjacent surfaces of the first cover element protrudes. The circumferential region of the second cover element which engages behind the annular catch on the first cover element can be continuous or can be formed by a plurality of segments which adjoin one another in the circumferential direction. Furthermore, there is also the possibility that the annular catch is formed by a plurality of projections formed on the first cover element, which are successively provided on a circular line concentrically surrounding the central axis.

At least one seal is provided on the first and / or second cover element, e.g. is produced either by applying or applying an appropriate sealing compound or else by molding and which closes the space between the lid elements at least in the region of the container opening and effectively prevents the filling material (beverage) from penetrating into the space between the lid elements.

In the container lid according to the innovation, the second lid element is also held or guided in the region of the central axis on the first lid element, using a fastening element which, for example, consists of the Material of the first cover element is shaped, for example as a rivet or snap rivet or snap pin.

In a further embodiment of the invention, the container lid and, in the case of a two-part design of this container lid, the lid elements consist at least partially of a plastic, preferably of a transparent plastic, e.g. made of PET. The container or can body is then also made from this plastic material. In the case of a container lid or first container element made of plastic, for example PET, a possibly existing sealing flap is formed, for example, by an insert which is made, for example, of sheet metal or of a suitable plastic. In the invention, the first and / or second cover element of the reclosable cover are made, for example, of metal or plastic. The second cover element, which is rotatably provided on the first cover element, is likewise made, for example, of metal (for example aluminum) or plastic, a plastic which is food-compatible being used as the plastic.

The invention is suitable for containers for liquid contents, for example for beverages. However, the invention is also suitable for containers for a powdery, granular or particle-containing filling material, for example for snack items or nuts etc.

In order to ensure secure closing, a suitable seal is provided on the rotatable second cover element and / or on the first cover element. This is applied to this component using a suitable technique, for example after the first or second cover element has been produced. In the case of production from plastic, there is also the possibility of producing the seal by injection molding or using the in-mold process. The break-open tab is made, for example, of metal or plastic or a combination of metal and plastic. In particular in the manufacture of the rotatable cover element and / or the break-open tab there is also the possibility not only to manufacture the parts in a so-called assembly injection molding process, but also to assemble them at the same time. Such an assembly injection molding process could then also be combined with a two-component injection molding process or in-mold process, that is to say, for example, the manufacture of the rotatable plastic cover element with the break-open tab made of a harder plastic material (e.g. PET) and the molding of the seal a softer, again food-compatible plastic material could be done in one operation.

If the break-open tab is a separately manufactured component, it is connected to the lid base of the first lid element and the rotatable lid part, for example by means of the rivet or pivot pin formed from the material of the lid base of the first lid element. In principle, there is also the possibility of providing the break-open tab on the rotatable cover element in a pivotable manner, for example by snapping it into place.

Furthermore, there is the possibility of designing the break-open tab and / or the rotatable cover element in such a way that the break-open tab can be fixed in place in a position running parallel to the upper side of the rotatable cover element.

Particularly when the center of rotation of the rotatable cover element is formed by a bearing pin or bearing element (also rivet) provided in the cover base of the first cover element, it is expedient to design the seal acting between the cover base and the rotatable cover element such that they also encloses this bearing journal etc. in a ring, so that a seal in the region of the bearing journal is ensured.

If the first cover element is made of plastic, there is the possibility that an insert made of metal is provided or injected in its cover base, this insert made of metal then having the area to be opened by pressing, so that the drinking or dispensing opening in the usual way can be opened by opening.

In the case of containers with a larger volume, it is possible, for example, to design the lid base of the first lid element with an enlarged diameter. This lid bottom of the first lid element is then provided with a section which protrudes somewhat above the top of the lid bottom of the first lid element facing away from the container interior, is of circular design and whose central axis is offset with respect to the container center axis. This section is then provided with the area to be opened by breaking open. On this section, the rotatable cover element for reclosing the dispensing opening is arranged in such a way that the rotatable cover element engages positively behind the cover base of the first cover element at its edge and is also rotatably connected to the first cover element in the middle of the section via a bearing element.

This design then has the advantage that, despite a large diameter of the container and thus despite a large container volume, a lid element with a relatively small diameter can be used for reclosing, ie a lid element, the strength and rigidity of which is sufficiently high due to the smaller diameter, especially in the case of a high internal container pressure, as is the case, for example, with a carbonated filling material (e.g. Beer, soft drinks, etc.) to achieve the required tightness of the reclosed container.

The container according to the invention is therefore particularly suitable for liquid and solid foods such as. B. drinks, coffee, coffee beans, peanuts, pistachios, biscuits, sweets such as candies, etc., salad oils but also for cosmetics such as shampoos, detergents, cleaning agents, gels and pastes, but also for technical fillings, such as. B. engine and gear oils etc.

In general, the lid of the invention is designed so that it with the usual

Sealing machines can be processed, in particular by rolling the first cover element onto the upper edge of the container. For this purpose, the cover is designed so that the edge of the first cover element is accessible for the tools used.

Furthermore, the cover according to the invention is designed such that it can be stacked together with a plurality of similar covers in a magazine of the capper by intermeshing or nesting.

In FIGS. 1-4, 1 is a lid for use in a beverage can, for example in a can for soft drinks or beer, which has this lid 1 and a bowl-like can body 2, which is provided with the lid 1 on its top (see FIG. 4 ). The lid 1 is tightly connected to the can body 2 in the usual manner and with the usual means, for example by folding 3 along an upper edge of the can, so that the lid 1 hermetically seals the can interior 4 to the outside.

The can body 2 is made, for example, of metal (e.g. aluminum or aluminum alloy) by deep drawing or of a suitable plastic, for example of PET.

The lid 1 consists of the lid element 5, which is also made, for example, of sheet metal, for example from a sheet of aluminum or an aluminum alloy, by deep-drawing, with a flat or substantially flat circular disk-shaped lid base 6, with a lid rim 7, one has a conically increasing diameter towards the top of the cover 1 and into one when the

The can body 2 merges with the rounded edge section 8 forming the fold 3. Between the lid base 6 and the lid edge 7, the lid with a Center axis M of the lid concentrically enclosing and open to the top of the lid annular groove 9 formed.

In the area of the lid base 6 and radially offset from the central axis M, a closure tab 10 is formed in the material of this base, which is used to open the

Beverage can or the lid 1 can be pressed inwards in a manner known per se, in such a way that when the lid 1 is open the tab 10 is still connected to the can bottom 6 in a part of the area into the can interior 3 to release a drinking opening 11. as indicated in FIG. 2 by the broken line 10 '. The tab 10 is made in one piece with the bottom 6 in that the edge line of the tab 10 is formed at least in a partial area by a predetermined breaking line, on which the material of the lid base is reduced in cross section. The tab 10 is reinforced by reinforcing beads or ribs 12.

To open the lid 1 or the drinking opening 11 there is an opening or rupture ring 13 provided on the top of the lid, which is designed as a substantially oval ring 14 with a central web 15 in a top view of the lid (FIG. 1), with Openings 16 and 17 on both sides of the central web 15. In the opening 17, which is closer to the closure flap 10, a flap 18 extends with which the rupture ring 13 is fastened to the top of the cover element 5 in the region of the central axis M, and by a short fastening rivet 19 formed from the material of the lid base 6. The ring body 14 and the central web 15 are rigid. The tab 18 is bendable. With the side facing away from the opening 16, the rupture ring 13 bears against the closure tab 10 when it is opened.

When the can is originally closed, the break-open ring 13 lies with its ring plane parallel or approximately parallel to the plane of the lid base 6, specifically within the of the lid rank 7 enclosed space, ie below the lid edge portion 8 or the edge of the beverage can formed by the fold 4.

A further cover element 20 is provided rotatable about the central axis M on the upper side of the cover base 6 facing away from the container interior 4. This cover element is designed in the form of a circular disk and has on the circumference a downwardly drawn and slightly rolled-in edge 21 which, on its inside facing the central axis M, forms a channel-like section 22 concentrically surrounding this central axis M and open to the central axis M, with which the Cover element 20 positively engages over an annular projection 23 concentrically surrounding the central axis M, which is formed at the transition from the cover base 6 to the subsequent annular groove 9 on the cover element 5. Through the edge 21 and the projection 23, the cover element 20 is held in a form-fitting manner on the cover element 5 over its entire circumference, in particular also secured against lifting off from the cover element 5. Nevertheless, the cover element 20 can be rotated about the central axis M relative to the cover element 5.

In the middle of the cover, the cover element 20 is rotatably held on the cover element 5 using the rivet 19. In order to achieve a low overall height and in particular also a small axial dimension for the rivet 19, the rupture ring 13 is provided with a crank 24 in an area surrounding the rivet 19, in such a way that the cover element 20 has an opening 25 thereon Crank of the break-open ring 13 or the tab 18 is rotatably mounted, while the break-open ring 13 is rotatably connected to the cover element 5 via this crank 24 and the rivet 19 about the central axis M. In the embodiment shown, the cover element 20 is made of plastic, preferably of transparent plastic (for example PET) and has an opening 26 which has the same size and, based on the central axis M, the same arrangement as the drinking opening 11. In the original sealed can, the opening 26 is congruent with the tab 10, so that using the break-open ring 13, the lid 1 can be opened such that the drinking opening 11 formed after the tab 10 is pressed in is accessible through the opening 26. By turning the cover element 20 relative to the cover element 5, the drinking opening 11 can be closed again by the cover element 20.

In order to facilitate the turning of the cover element 20, two handles or catches 28 are formed on the cover element 20, which protrude slightly above the top of the cover element 20. The drivers 28 are located on both sides of the rupture ring 13 on a common axis intersecting the central axis M.

In the embodiment shown, the break-open ring 13 is also rotated about the central axis M when the cover element 20 is rotated. For this purpose, the cover element 20 has two catches or projections 29 on the upper side, which extend into the opening 16 and carry the break-open ring 13 when the cover element 20 is rotated.

The cover 1 is mounted in such a way that the cover element 20 is first placed on the top of the cover base 6 and pressed against the cover base 6 in such a way that the section 22 resiliently engages on the ring-like projection 23. Following this, the rupture ring 13 is placed on the preformed rivet 19, so that the crank 24 is arranged in the bore 25 of the cover element 20 and the projections 29 engage in the opening 16. The rivet is then deformed in a further process step 19, so that the break-open ring 13 and with it the cover element 20 are finally held on the cover element 5.

As FIG. 2 also shows, the cover element 20 in the embodiment shown is recessed at the top where the break-open ring 13 is provided, in order to reduce the overall height as a result.

An essential peculiarity of the cover 1 is therefore that the annular groove 9 and the entire height of the cover edge 7 are kept free of the cover element 20, i.e. are not covered by this cover element, so that the cover 1 can be processed with the conventional closing tools, which require the cover edge 7, which is freely accessible over the entire height, to roll the edge section 8 and to form the fold 3.

To close the open drinking opening 1 1 tightly through the

To reach the cover element 20, the cover element 5 is provided in a region surrounding the drinking opening 11 with a circumferential seal 30 which is provided in a groove which is open at the top of the cover base 6 and molded in this cover base, by applying a suitable sealing compound ,

FIG. 5 shows a further possible embodiment of a cover 1 a, which differs from the cover 1 essentially only in that instead of the seal 30, two seals 31 and 32 are applied to the underside of the cover element 20 adjacent to the cover base 6 of the cover part 5 a, namely a circumferential seal 31 on the edge area surrounding the opening 26 and a circumferential seal 32 of the same shape, size and position with respect to the central axis M at an area offset from the opening 26 by a predetermined angular amount about the central axis M. Through the seal 31 is at opened drinking opening 1 1 the space between the lid base 6 and the lid element 20 sealed around this drinking opening. The seal 32 seals the transition between the lid base 6 and the lid element 20 when the lid element 20 is rotated into its position closing the drinking opening 11. In this embodiment, the cover element 1 a has stops, which provide for defined end positions of the cover element 20 for the state “drinking opening 11 released” and “drinking opening 11 closed”.

FIGS. 6-8 show, in individual representation, a further possible embodiment of the invention, a cover element 20a, which can be used instead of the cover element 20 of FIGS. 1-5. The cover element 20a differs from the cover element 20 essentially in that the catches 28a corresponding to the catches 28 are accommodated in depressions 33 on the upper side of the cover element 20a, so that there is a particularly low overall height. Furthermore, the drivers 28 are designed so that they widen towards their free end and form tapered edges there, which increases the grip. Instead of the applied seals 31 and 32, molded seals are provided on the cover element 20a, of which only one of these seals, namely the seal 31a corresponding to the seal 31, is shown.

The seals 30, 31 or 32 are applied using suitable techniques, for example by printing on a suitable sealing compound (elastomer) which hardens after the printing.

Figures 9 and 10 show a top view and in section as a further possible embodiment of a lid 1 b, which differs from the lid 1 essentially in that it is for use in a can body 2b is determined, which is made of plastic, preferably PET. Instead of a lid element 5 made of metal, a lid element 5b is used, which is also made of plastic, preferably PET, and whose shape corresponds essentially to the shape of the lid element 5, but with the difference that the drinking opening 11 in the original closed state of the beverage can or the lid 1 b is closed by an insert 10b, which is made in the embodiment shown as a sheet metal part and can be pressed inwards by means of the opening ring 13 to open the beverage can or the lid 1 b. Instead of the rivet 19 produced by material deformation, a rivet 19b is molded onto the cover element 5b. The rivet 19b is designed as a rivet on which the rupture ring 13 with the opening provided on the ring plate 18 is then fastened by snapping. 34 is a projection which is formed on the top of the cover element 5b and engages in a partially annular recess 35 on the underside of the cover element 20. The recess 35 extends on a pitch circle which is concentric to the central axis M, namely over an angular range which corresponds to the permissible range of rotation of the lid element 20 and is selected such that the drinking opening 11 can be closed again by rotating the lid element 20.

The lid 1b is fastened to the can body 2b using suitable means, for example by ultrasonic welding and / or gluing in the region of a fold 3b. The cover element 20 is in turn made of plastic, preferably of PET. FIGS. 1 1 and 12 again show the can body 2 b with the cover element 5 b, but with the rupture ring 13 and cover element 20 removed.

FIGS. 13 and 14 show representations similar to FIGS. 9 and 10 as a further possible embodiment of a cover 1 c, which is also suitable for use in a PET can, ie when used with the can body 2b made of plastic (PET) is determined and suitable. The cover 1 c differs from the cover 1 b essentially only in that instead of the insert 10b, an insert 10c made of sheet metal is provided, which also forms the molded rivet 19. FIGS. 15 and 16 in turn show the cover element 5c of the cover 1c with the breaker ring 13 and cover element 20 not yet installed.

Figures 1 7 and 18 show in top view and in section a lid 1 d for a PET beverage can, i.e. for use with the can body 2b. The cover 1 d essentially consists only of the cover element 5 d, which is produced from a metal sheet, for example from a sheet of aluminum or an aluminum alloy, with a shape that essentially corresponds to the shape of the cover element 5. The lid element 5d is tightly connected to the edge of the can body 1b in a suitable manner, for example by gluing, welding or in another suitable manner. Instead of the breakable tab 10, the cover element 5d has an opening 36 which forms the drinking opening and which forms an edge 37 which extends into the interior of the can body 2b. To enable complete emptying of the contents of the beverage can, slots or openings 38 are provided in the edge 37 in the immediate vicinity of the underside of the lid element 5d. The opening 37 is closed by an attached or screwed on closure element 39. The associated screw-in thread can be made with one or more threads, preferably with a high pitch, so that the closure element 39 can be removed or reattached with a small turn.

Since the thread for the closure element 39 is provided on the edge 37 projecting into the interior of the beverage can, the closure element 39 stands by sealed can only slightly above the top of the bottom of the lid member 5d, so that the closed closure member 39 protrudes only slightly upward above the lid base and thereby the stackability of several sealed cans is not affected.

The tightness between the cover element 5d and the closure element 39 is ensured, for example, by the self-sealing thread, but by an additional seal, not shown. There is also the possibility of designing the closure element 39 in such a way that tamper-evident protection is provided, specifically in such a way that when the closure element 39 is opened for the first time, a

Sealing, for example in the form of a perforation, must be mechanically destroyed so that an already opened beverage can can be clearly recognized as such.

It was assumed above that the cover element 5d is made of sheet metal. Of course, there is also the possibility of also producing this cover element from plastic, for example PET, in which case, according to FIGS. 19 and 20, the cover labeled 1 e there can also be produced in one piece with the can body 2b during manufacture. The can is then filled with the liquid filling material (beverage) via the opening 36 which, after filling, is closed with the closure element 39.

Instead of insert parts 10b or 10c made of metal or sheet metal, those made of a suitable plastic can also be used.

The invention has been described above using exemplary embodiments. It goes without saying that numerous changes and modifications are possible without thereby departing from the inventive idea on which the invention is based. It was assumed above that the cover element 20 or 20a is made of plastic. Of course, there is also the possibility of producing this cover element from metal or sheet metal. Furthermore, regardless of the respective choice of material, the edge 21 of the cover element 20 or 20a can be segmented or provided with incisions, so that the engagement of this edge on the ring-like projection 23 is facilitated, even if the projection 23 engages with a particularly positive engagement the edge 21.

Furthermore, with a correspondingly long design of the rivet 19, there is of course also the possibility of rotatably mounting the respective cover element 20 or 20a directly on this rivet, the embodiment described with the rotatable mounting of the cover element 20 or 20a on the crank 24 having the advantage of short design of the rivet 19 and thus has the advantage of a low overall height and the avoidance of excessive material stress when molding the rivet 19.

Above it was further assumed that the seal 30 provided on the lid base 6 is designed as an annular seal enclosing the drinking opening 11. Preferably, however, this seal has a width in the direction of rotation of the cover element 20 such that in every rotational position of the cover element, in particular also in positions in which the drinking opening 11 and the opening 26 only partially overlap, the gap or formed in the region of these openings Transition between the lid base 6 and the lid member 20 or 20a is completely sealed, so that even one only partially

Overlap of the drinking opening 11 and the opening 26, ie if the drinking opening 11 opens the filling opening only partially, ie the drink is not between the lid base 6 and can reach the cover element 20. The shape or the course of the seal 30 is indicated for this case in FIG. 1 with the broken line 30 '.

FIGS. 21-34 show in different representations the different elements of a reclosable cover 1f of a further embodiment of the invention. The cover, which is suitable, for example, for the can body 2, in turn consists of the cover element 5f, which corresponds to the cover element 5 with the cover base 6 and can be fastened to the can body by rolling, with the cover base 6f, which is made of metal (aluminum), for example, and with a shape corresponding to the cover element 5. Furthermore, the cover 1f consists of the rotatable cover element 20f, which corresponds in function to the cover element 20 and is made, for example, of plastic or metal. With the aid of the rivet 19 formed in the middle on the cover base 6f, the cover element 20f is rotatably held on the cover base 6f. With the edge 50 corresponding to the edge 22, the cover element 20f is positively but rotatably held on the cover element 5f or on the cover base 6f by pressing and latching on its periphery. The edge 50 engages behind the ring-like projection 51, which corresponds to the projection 23. With the rivet 19, the break-open tab 52 is also held on the lid base 6f or on the lid element 20f.

On the underside facing the lid base 6f, the lid element 20f has two systems 53 starting from the edge 50, which cooperate with a projection 54, which is pressed out of the material of the lid base 6f and protrudes over the top of the lid base. The two systems 53, which are provided offset by approximately 180 ° relative to one another with respect to the central axis of the cover element 5f, limit the rotary movement of the cover element 20f to an angular range of approximately 180 ° or somewhat less. The lid base 6f is in turn designed with the area 55 that can be pressed in, which, when pressed in by means of the break-open tab 52, opens the drinking opening. An opening 56 corresponding to this area 55 or the opened drinking opening is provided in the cover element 20f. When the lid 1 f is closed (original closure) and also when the drink opening is open and opened, the open area 55 and the opening 56 are congruent. When the cover 1f is closed again, the cover element 20f is rotated such that the opened area 55 (drinking opening) is covered by the cover element 5f.

On the underside facing the cover bottom 6f, the cover element 20f is provided with a seal 57 which is essentially in the form of an eight and which runs on the one hand along the edge of the opening 56, specifically with a sealing section 57 '. A sealing section 57 ″ is formed opposite the sealing section 57 ′ in mirror image to an axis of symmetry SA. The two systems 53 are also arranged symmetrically about this axis of symmetry intersecting the central axis of the cover element 20f. When the opening 56 is congruent with the area 55, the seal lies with its Section 57 'against an edge area surrounding the area 55 on the lid base 6f. When the lid 1f is closed again or when the drinking opening is closed again (opened area 55), the section 57 "bears against an edge surrounding the area 55 against the lid base 6. As shown, the seal 57 is also designed in such a way that it also encloses the central opening 58 in the cover element 5f for the rivet 19 with a section 57 ′ ″, so that the cover element 20f in the region of the rivet 19 is sealed even in the case of the originally sealed box is closed, for example, no liquid can get between the lid base and the lid element from the outside of the lid element 20f, in the embodiment shown, the break-open tab 52 is made of sheet metal, in the usual shape, but the cover element 20f indicates its top in addition to the protruding from the top, for example molded and driving or grip surfaces forming projections 59 on further projections 60, which form tabs for the break-open tab 52, in such a way that this break-open tab after Breaking open of the region 55 can be moved back into a position lying flat against the upper side of the cover element 20f and can be locked there by latching on the latching elements 60.

The cover 1f is in turn designed so that it passes through a plurality of identical covers in a closing machine or in a magazine there, etc.

Is stackable in each other and can therefore be processed with conventional closers. For this purpose in particular the cover element 20f is also designed to be as flat as possible.

The seal 57 is applied in a suitable manner, for example, after the cover element 20f has been produced. In particular when the cover element 20f is made from plastic, there is also the possibility of molding the seal 57 or of producing it in an in-mold process with the cover element 20f. A food-compatible plastic, for example PET, is used as the plastic material for the cover element 20f.

It was assumed above that the break tab 52 is made of metal. Of course, there is the possibility of partially or completely manufacturing the breakout flap from plastic. Furthermore, when the cover element 20f is manufactured, there is the possibility of integrally forming the break-open tab on this cover element via a material section which acts as a hinge. FIGS. 35-42 show the cover element 20g in another possible embodiment in different views. This cover element is preferably made of plastic and differs from the cover element 20f essentially in that two bearing elements 61 are formed on both sides of the opening 58 at the top of the cover element, into which as a molded part or as

Injection molded part made of plastic break tab 62 with trunnion 63 can be attached by snapping. For this purpose, the bearing elements 62 have bearing openings 64, which are open on a side facing the opening 58, but, when the bearing journal 63 is engaged, enclose the latter in each case over a peripheral region of more than 180 °. Since the bearing openings 64 are open toward the opening 56, the bearing journals 63 are not pressed out of their bearing elements 61 when the region 55 in the lid base which exposes the dispensing or drinking opening is broken open.

By appropriate design of the bearing pin 63 and the associated

Bearing openings 64 can also be achieved in that the break-open tab 62 is moved back after breaking open the drinking opening while latching into its position lying flat against the upper side of the cover element 20g. The assembly of the cover element 20g on the cover base, not shown, for example on the cover base 20f of FIGS. 21-24, is again carried out, for example, by

Pressing the cover element 20g and then riveting it with the rivet 19 formed from the cover base. In principle, however, there is also the possibility of the so-called assembly injection molding process, in which the cover element 20g is sprayed onto the cover base, the break-open tab 62 then being mounted. In principle, there is also the possibility of producing the cover element 20g with the break tab 62 in the so-called assembly injection molding process, for example by first molding one of the two parts by injection molding and then the other part is injected in such a way that the articulated connection between the break tab 62 and the cover element 20g is obtained.

As shown in FIGS. 41 and 42 in particular, the journals 63 are located closer to one end than the other end. At one end, the break-open tab 62 has a strip-like projection 65, which comes into contact with this area when the area 55 of the lid bottom which releases the dispensing or drinking opening is broken. The other end, which is further away from the bearing pin 63, serves as a grip surface when breaking open.

FIGS. 43-49 show in different representations, in particular also in different representations of the individual parts, a reclosable container with a larger volume and with a reclosable lid. The container, which is generally designated 66, consists of the container or can body 2 h, which is closed on its top with the lid 1 h. The lid 1 h comprises the lid element 5h with the lid base 6h, which is shaped corresponding to the lid base 6 in an area 6h 'offset from the container central axis BMA, with a section 67 pressed out of the material of the lid base 6h, which is annular to the central axis M is formed and its shape corresponds to the central region, for example of the lid base 6, and in particular also has the edge 51 corresponding to the edge 23, which the rotatable lid element 20h engages behind on its circumference. The section 67 has the area 68 corresponding to the area 55 which can be pressed in to open the drinking opening. The cover element 20h is designed like the cover element 20g and is held rotatably about the axis M on the section 67 and secured against lifting off in the region of the central axis M on the cover base by a rivet formed from the material of the cover base 6h. The cover element thus corresponds in terms of function and design 5h the cover element 20g. Of course, the cover element 20h can also be designed correspondingly, for example, corresponding to the cover element 5f or the other cover elements described above, in particular also with regard to the break-open tab 69, which corresponds to the break-open tab 62. The embodiment of FIGS. 43-49 can therefore be described in that the lid base 6h has an enlarged diameter for the large-volume container 66 and that the resealable section 67 of the lid base, which has the drinking or dispensing opening, is designed in accordance with the lid of a smaller-diameter can is, again with the rotatable lid member used in the small diameter cans or containers.

It was assumed above that the respective rotatable cover element 20, 20f, 20g, 20h is rotatably connected to this cover part by riveting the rivet 19 formed from the material of the non-rotatable cover part. But there is also the possibility of attaching the rotatable cover element both on its circumference and in the middle by clip-like engagement to the element 19b, which is then designed as a locking pin, so that after the element 19b is engaged, this in turn acts as a pivot for the rotatable element Cover element 20 - 20h serves.

As FIG. 50 shows, the seal provided on the rotatable cover element, namely, for example, the seal 57 designed as a narrow web or its sections 57 ′ and 57 ″ act with a raised, ie protruding beyond the top of the cover base 6f and the dispensing or drinking opening after the region 55 or 58 surrounding edge region 55 'has been pressed in, both in the starting position of the rotatable cover element with region 55 not yet open, in which (state) the section 57' of the seal 57 bears against the edge region 55 ', as well as the closed container, in which the section 57 ″ of the seal 57 bears against the edge region 55 ′. The seal 57 is concave in cross section on its lower, free side in accordance with FIG. 50, specifically in the embodiment shown with a groove 70 which extends along the seal and is open on the underside, so that rotation of the rotatable cover element 20-20 h can be achieved with little effort as well as tight reclosing.

In the figures 50 and 51, 71 also designates a leading seal, which also encloses the seal 57 and is provided on the underside of the rotatable cover part 20f, for example by injection molding. The seal 71 has a cross section tapering towards its free end (FIG. 50), in such a way that the inclination of the outer side 71 ′ facing away from the seal 57 with respect to a perpendicular to the plane of the rotatable cover part is approximately 5 ° and the inclination the inner side 71 ", ie on the side facing the seal 57 in the illustrated embodiment, is approximately 15 °. As shown in FIG. 51, the seal 71 is offset radially inward in the area between the two stops 53, so that the stop 54 in each rotational position of the rotatable cover element with respect to the axis of rotation with respect to the seal 71 is offset radially outwards, the seal is not damaged by the stop 54. The seal 71 ensures that, for example, also in the usual after filling and Closing a container washing and drying process no cleaning liquid between the ni Not rotatable and the rotatable cover element can get. Since the seal itself interacts with a clear area of the non-rotatable cover element, an optimal sealing effect is guaranteed. The height of the seal 71 is selected so that it is only very slightly circumferential against the non-rotatable cover element 5f, but the sealing effect is achieved, so that an increased effort when rotating the rotatable cover element through the seal 71 is not required. To do that To facilitate rotation of the rotatable cover element 20f, a lubricant is mixed with the material for the seals 57 and 71 used.

As mentioned above, the area 57 which forms the delivery opening after being broken open is provided with a raised edge 57 '. Here there is the possibility that this raised edge extends into the opening 56 of the rotatable lid element when the container is originally sealed, and this also supports the fact that the non-rotatable lid element is caused by an internal pressure of the originally closed container, for example by the C02 pressure of the originally closed container Container is accordingly curved outwards. Only after

When section 57 is broken up, the internal pressure escapes, so that the curvature of the non-rotatable cover element decreases to such an extent that rotation of the rotatable cover element 20f is possible.

There is also the possibility of on the top of the non-rotatable

Cover element 5f to provide a wide variety of symbols or information, for example winning or lottery numbers for competitions, symbols, can identification numbers and the like. These symbols and information are attached in such a way that they are only visible after turning the rotatable cover element from the original position, for example, to the reclosable position. *

Above it was further assumed that the respective container lid in a fully assembled state, i. H. in the case of a rotatable lid element mounted on the lid base of the non-rotatable lid element, is fastened to the container body, for example by rolling on. Basically, there is also

Possibility to design the lid base and the rotatable lid element so that the rotatable lid element is only applied to the non-rotatable lid element after the container has been closed, for example by Press on and click into place or in another suitable way. Here, too, it is again ensured that the rotatable cover element is guided in a form-fitting manner on its periphery, but rotatably on the cover base of the non-rotatable cover element and is rotatably connected to this cover base in the middle via a bearing pin or the like.
