    Plate with opening aid for cans
    The present invention relates to a plate with an opening aid for cans.
    Various types of closure are known for beverage cans. They can be roughly divided into slide, clip, rotation and lid locks.
    A slide lock is characterized in that a closure element is attached to the beverage flap of the beverage can in order to close the opening of the beverage can. US 57 85 199, US 60 98 830, US 67 22 518 B1 and US 53 51 853 disclose such slide closures for beverage cans. In US 60 98 830, US 67 22 518 B1 and US 53 51 853, the closure has rail elements which can accommodate the opening clip of the beverage can and thus stabilize the closure. By placing the opening clip of the beverage can on the closure device, the closure device itself is pressed against the can. The opening is thus closed. In US 57 85 199 the closure is pulled through the flap of the opening clip and turned over, a plate being provided which closes the opening of the beverage can.
    In US 2009 00 01 092 A1, US 8 727 164 B1, US 75 00 577 B2, US 36 37 104 and US 38 50 334 different types of clip closures for beverage cans are disclosed. They are characterized by the fact that the opening of a beverage can is closed by a clip which is inserted into the opening of the beverage can. In US 2009 00 01 092 A1, US 75 00 577 B2 and US 38 50 334 the clip holds itself on the edge of the opening of the beverage can. In US Pat. No. 8,727,164 B1, the closure clip is connected to the opening clip so that the opening clip enables it to be closed again. US 36 37 104 discloses a hook and a closure plate, the closure plate being placed in the opening and the hook being clamped on the can edge so that the closure plate presses from below against the lid of the beverage can and thus closes the opening.

    US 2013 016 8457 A1, EP 08 16 248 A1, WO 2010/109341 A1, US 63 21 927 B2, US 8 881 940 B2, US 5 199 591, US 49 13 304, US 488 0136 and US 52 85 924 are various lid closures for beverage cans disclosed. They are characterized in that a closure is placed on a beverage can, which at least partially covers the lid of the beverage can. The opening of the beverage can is also covered.
    Several rotary fasteners emerge from DE 44 27 812 A1, DE 197 44 245 A1, DE 100 18 685 C2, DE 39 31 573 A1, US 47 17 039 and US 46 81 238. DE 44 27 812 A1, DE 39 31 573 A1, US 47 17 039 and US 46 81 238 are characterized in that the closure is connected to the rivet in the middle of the lid. The closure is thus designed to be rotatable and can close the opening of the beverage can by a corresponding rotation. Due to the connection with the rivet, production of the can is necessary. DE 197 44 245 A1 and DE 100 18 685 C2 show two rotation locking hooks which are characterized in that the locking mechanism can be pushed onto the cover so that rotation around the rivet is made possible. The rivet in the middle thus serves as an anchor point. The opening clip of the can prevents the rotary lock from becoming detached.
    DE 197 44 245 A1 discloses a rotation locking hook which can be pushed onto the cover so that rotation around the rivet is made possible. US 2013 016 8457 A1 has a hook-shaped edge anchor element, as a result of which the closure is anchored on the edge of the can and can thus be made rotatable.
    The invention is based on the object of providing a plate with an opening aid for cans which can be produced simply and inexpensively.
    Another task of the small plate with an opening aid is that, simply by turning it, an opened can is reliably fired with little resistance.
    One or more objects are achieved by the subject matter of the independent claim. Advantageous developments and preferred embodiments form the counterpart
    stood the subclaims.
    The face of a can has a rivet and a raised edge. A lever for opening the can is attached to the rivet.

    The plate has an upper and a lower side, a central and an outer, radial edge and two lateral edges which each connect one end of the central and radial edge.
    The plate is made of metal and designed in such a way that an indentation is formed on the central edge which can accommodate or enclose the rivet of a can.
    The plate has one or more opening aids. The opening aids are protrusions formed on the top of the plate. They are arranged in such a way that they can engage the lever of the can when the plate is rotated. Opening the can is made easier by lifting the lever that opens the can.
    The opening aid is preferably formed in the third or fourth quarter on the route from the central edge to the radial edge of the closure. In this area, the lever can engage and the leverage to push the lever up is greater than if it is further to the central edge.
    Due to the platelet shape, it is easy to manufacture, e.g. by punching processes in which the platelets are punched out of plates.
    The plate can be rotated around the rivet. The movement of the plate is guided through the recess adjacent to the rivet. The guide on the rivet makes it easy to move.
    If the plate is turned, the opening aid can slide under the lever of the can and lift it up slightly. This simplifies opening of the can.
    Due to the platelet-shaped design, it does not protrude beyond the edge of the can, which means that the can remains stackable. The plate can also be placed on a can which is closed per se during its manufacture. The dispatch of cans which are grouped together in several pallets is not hindered by placing a closure on each of the cans.
    On at least one or adjacent to one of the lateral edges, the plate can have a
    Have a projection which protrudes from the top of the plate in such a way that it serves as a sliding aid for the plate.

    The plate can have a rough surface on at least one or adjacent to one of the lateral edges, which surface serves as a sliding aid for the plate.
    The sliding aid for the plate can be designed as a thin wall. If the plate with the indentation is first inserted into the rivet of the can and placed on the lid of the can adjacent to the lever of the can, it is possible to push the plate slightly under the lever of the can, for example with the thumb.
    If the plate has a rough surface that serves as a pushing aid, this can also be designed as a ribbed surface. With the help of this surface, a frictional connection can be formed between the plate and, for example, the thumb, which enables the plate to be easily pushed under the lever of the can.
    The plate preferably has a thickness of at least 0.25 mm or 0.5 mm or 0.75 mm or 1 mm.
    The central edge is preferably narrower than the radial edge. The rotation of the plate is mainly guided by the recess on the central edge along the rivet of the can. This makes it possible to make the central edge of the plate narrow. The radial edge of the plate, however, is expediently wider, since the plate should completely pass under the lever of the can in order to be able to engage with it well. The plate thus has approximately the shape of a triangle, whereby material can be saved due to the tapering at the central edge.
    The elevations can be a bend in the plate at the radial edge. A bend is particularly easy and inexpensive to manufacture in production. The closure is preferably punched. During the punching process, the radial edge can be bent at the same time.
    The elevations are preferably formed obliquely approximately along a direction transverse to the radial direction of the plate.
    The elevations can have a gradually increasing inclination which runs approximately transversely to the radial direction of the plate.
    If the elevations are formed obliquely approximately along a direction transverse to the radial direction of the plate and have a gradually increasing inclination in this direction,

    then the plate can be pushed more easily under the lever of the can when turning and it can be lifted more easily.
    The elevations preferably rise evenly over a distance of at least 1 mm or 2 mm or 3 mm.
    The elevations can have a height of at least 0.25 mm or 0.5 mm and a maximum height of 1 mm or 0.75 mm.
    The underside is preferably coated with a plastic, in particular polyethylene terephthalate (PET), polytetrafluoroethylene (PTFE) or polypropylene (PP). They are inert to most of the contents of cans, so there is no loss of taste. Furthermore, they can reduce the friction between the closure and the beverage can, which promotes rotation.
    The top is preferably labeled. This label is used to gain information for a user and can include, for example, advertising, product information or logos.
    The plate can be designed in such a way that an opening of a beverage can is completely covered, in particular after a 180 ° rotation.
    This can be to prevent insects or other debris from entering the beverage can. Furthermore, carbonated beverages retain their taste longer, as the carbonic acid cannot escape through the air as quickly.
    The radial edge preferably has a curvature. The curvature follows the raised edge of the beverage can at approximately the same distance. As a result, a grooved anchor can be formed on the radial edge, the grooved anchor being an elevation from the plate which engages in a groove in the beverage can.
    If the plate includes, in addition to the savings that the rivet of the can can accommodate, also a groove anchor, there is another guide point which, by engaging in the groove of the beverage can, enables the plate to be turned more easily.
    The groove anchor is preferably over the entire length of the radial edge of the plate
    educated. This causes a uniform load over the entire length of the radial edge of the plate.

    The groove anchor is preferably adapted to the shape of the groove of the beverage can with regard to the circular shape of the groove and the cross-sectional shape of the groove. In particular, the groove anchor is designed in such a way that it rests in a form-fitting manner on the inner delimiting surface formed by the groove. In addition, the groove anchor can also be designed in such a way that it rests in a form-fitting manner on an outwardly facing boundary surface of the groove.
    The shape of the groove anchor can be adapted to the groove by bending the plate. The groove anchor can, however, also be a body that is thicker than the rest of the plate and extends into the groove.
    The plate may have a passage such as a hole or sieve. This passage can be small enough to prevent insects from entering the can, but still large enough to allow them to drink from.
    This is the case, for example, with a sieve-like passage. Alternatively, the passage could be large enough to hold a straw in place.
    The beverage can can have a pre-stamped section in the area of the opening, which can be pressed into the beverage can with the lever of the beverage can.
    A can system may comprise a can and a can-opening-aid plate.
    The plate is preferably attached to the can with opening aids for cans. The can system can thus be sold as a unit. The invention is explained in more detail below using the drawing as an example. The drawings

    A plate for cans 2 has at least one opening aid 15. The plate 1 is designed to lift a lever 11 of the can.
    In this exemplary embodiment, the plate is provided as a protective cover 1 for beverage cans 2. The beverage can 2 typically has a rivet 4 with a rivet head 14 in the middle on one side. The rivet head 14 is a flat, mostly round plate which is arranged at the end of the rivet 4 and has a larger radius than the rivet 4. On the rivet 4 of the lever 11, a cover part 12 is arranged to be pressed in. The rivet head 4 prevents the lever 11 from being unintentionally released. The beverage can 2 has a groove 5 and a raised edge 6 on the edge.
    The plate of the protective cover 1 has, in plan view, approximately the shape of a sector of a circle with a radius r and a center angle a around a center point M of a circle (FIG. 2c). The shape of the plate is selected such that the central angle a is large enough that the plate can cover the opening 3.
    The center of the circle M lies on a central edge 7 of the protective cover 1 and is arranged in such a way that it is congruent with the center of the rivet 4 of the beverage can 2 when the protective cover 1 is arranged on the beverage can 2.
    The central edge 7 forms a circular segment-shaped recess in plan view. The radius of the circular segment-shaped recess corresponds at least to the radius of the rivet 4.
    The protective cover 1 has an indentation 9 around the center of the circle M for receiving the rivet 4. The indentation 9 is designed to be segment-circular.
    The protective cover 1 has two attachments 13.
    The attachments 13 are an integral part of the plate and extend in the same plane as the plate. When the protective cover 1 is inserted on a beverage can 2, the attachments 13 protrude laterally at the edge of the opening 3 of the beverage can 2, the rivet 4 being laterally encompassed by the two attachments 13, similar to a fork. When the protective cover 1 is inserted onto the beverage can 2, the attachments 13 ensure that the protective cover 1 does not inadvertently dip its narrower central section into the opening 3 and get caught there. There are differently shaped openings 3 on beverage cans. There are also openings here that are approximately segment-shaped in plan view and extend very close to the rivet 4 (not in FIG. 1

    shown). With such openings there is the risk, if the closure is narrow in the central area, that the protective cover 1 will dip into the opening 3 of the beverage can 2 and become obscured there when it is attached to the beverage can. This is prevented by the intentions 13.
    Another possibility, not shown here, is that the two attachments 13 enclose the rivets 4.
    In the top view, the protective cover 1 is only as large as it makes sense for the function of the closure and is necessary to cover the opening 3 of the beverage can 2. The protective cover 1 is a mass-produced item. The smaller it is designed, the cheaper it is to manufacture. In addition, users can simply keep a small protective cover 1 in a wallet or the like.
    The radius r of the circular sector essentially corresponds to the usual distance between the rivet 4 and the groove 5 of the beverage can 2.
    The radius r of the circular sector is smaller than the usual distance between the rivet 4 and the raised edge 6 of the beverage can 2.
    The protective cover has two opening aids 15. The opening aids 15 are elevations pointing upwards from the can. They are approximately three-quarters of the way from the central edge to the radial edge of the closure. Each opening aid 15 is a tetrahedron which is triangular in plan view and points along a direction transverse to the radial direction of the beverage can. Thus, an edge 17 of the tetrahedron is inclined along a direction transverse to the radial direction of the beverage can.
    In principle, other geometries of the opening aid 15 are also conceivable. Provided that they have at least one inclined side which is formed transversely to the radial direction of the beverage can 2.
    In this embodiment, the opening aids 15 are punched.
    The protective cover 1 has a radial edge 8 opposite the central edge 7. The protective cover 1 is formed on the radial edge 8 with a groove anchor 10 which can engage in the groove 5. This groove anchor 10 is formed in this embodiment by a bend of the radial edge 8, the radial edge 8 in such a way down

    is bent that it engages in the groove 5 of the beverage can 2 (Figure 3e and 3h). The width of the curved section corresponds approximately to the depth of the groove 5.
    Alternatively, the radial edge 8 can also be bent twice and form a V-shape in a side view. The grooved anchor 10 here also has a projection extending towards the raised edge 6 (FIG. 3f).
    Another possibility is that the groove anchor 10 is bent three times (FIG. 3g). In comparison to the previous alternative, the grooved anchor 10 here also has a projection pointing in the direction of the central edge 7 (FIG. 3g).
    The groove anchor 10 can also alternatively adapt to the shape of the groove 5 (FIGS. 3a to 3d).
    Another alternative is given by the fact that the groove anchor 10 protrudes from the underside of the protective cover 1 through additional material. In the side view, the protective cover 1 has a thickening at this point. This can consist of the same material as the rest of the protective cover 1 or of a different material.
    The protective cover 1 is attached to the beverage can 2 by first pressing the central edge 7 against the rivet 4 and then pressing the groove anchor 10 into the groove 5. The protective cover 1 is now attached to the beverage can 2 so as to be rotatable about the rivet 4. The protective cover 1 is pressed against the surface of the beverage can 2 by the rivet 4, the rivet head 14 and / or the lever 11. The detachment of the protective cover 1 from the beverage can 2 is thus prevented.
    Alternatively, the groove anchor 10 can only be arranged in sections on the radial edge 8 of the protective cover 1 (see FIG. 2e).
    The shape of the protective cover 1, in particular the attachments 13 and the size of the central angle a, can vary depending on the beverage can 2 (FIGS. 2d, 2e and 2f).
    If the beverage can has an overhang 16 on the raised edge 6 which points in the direction of the center of the can, the protective cover 1 can extend up to this overhang 16 and
    is additionally secured by this (Figures 3a and 3b).
    Another embodiment of the plate 1 has only a single opening aid 15, which is arranged adjacent to a lateral edge 18 of the plate 1. The

    lateral edge 8 extends between one end of the central edge 7 and one end of the radial edge 8 (Fig. 4a).
    The opening aid is designed as an elevation which, as in the embodiments explained above, has an edge 17 which runs approximately in the tangential direction, that is approximately parallel to the radial edge 8. The edge 17 of the opening aid 15 has a substantially uniform inclination, which slopes in the direction from the lateral edge 18, to which the opening aid 15 is arranged adjacent, to the center of the plate until the edge 17 reaches the level of the surface of the plate 1 Has. The angle 19 which the edge 17 encloses with the surface of the plate 1 is preferably at least 3 °, in particular at least 5 ° and particularly preferably at least 8 ° (FIG. 14). The maximum angle 19 is smaller than 30 and preferably smaller than 20 °. Due to the gradual slope of the edge 17, the opening aid can be pushed under the lever 11 of the can with little effort, the lever being lifted upwards by the opening aid. The opening aid 15 spreads like a wedge between the surface of the can and the lever.
    The plate 1 has a grip area 20 which is arranged on the adjacent other side edge 18 (FIG. 4a). In the present exemplary embodiment, this grip area is formed by a number of embossed points that protrude slightly upwards. These thus form a rough surface, so that a shifting torque can easily be transferred to the plate 1 on the grip area with a finger in order to rotate it and push it under the lever 11 with the opening aid 15.
    The grip area can also be formed by a different type of roughening, such as, for. B. by sandblasting this section. The grip area is preferably much less raised than the opening aid 15, which makes it possible to insert the plate 1 under a lever that first the grip area is pushed through under the lever until the plate 1 is arranged so that the lever is in the area is located between the grip area 20 and the opening aid 15.
    Another embodiment relates to a plate 1 for a fish box 2 (Figure 5a), in which a lever 11 for pulling off the lid of the fish box 2 with a rivet 4 is adjacent.
    beard is attached to the edge of the fish box 2.
    In this exemplary embodiment, the cover 1 is provided with a through opening 21 through which the rivet 4 extends. The plate 1 is thus used during manufacture

    the can is attached to the lid of the fish can 2 together with the lever 11. The plate 1 is shaped asymmetrically in plan view with a radial edge 8 and two side edges 18, the side edges 18 adjacent to the rivet 4 merging into an arcuate edge 7 which is spaced a little apart from the rivet.
    As in the embodiment described above, this plate 1 also has an opening aid 15 and a grip area 20. In this exemplary embodiment, however, the opening aid 15 and the grip area 20 are arranged adjacent to one another, the grip area 18 being located directly next to one of the lateral edges 18 and the opening aid 15 being offset a little towards the center of the plate 1 with respect to the grip area 20. As a result, as can be seen in FIG. 5 a, the plate 1 can be rotated about the center 4 in the direction of a double arrow 22 so that the opening aid 15 is pushed under the lever 11. Due to the asymmetrical arrangement of the opening aid 15 and the grip area 20, there is sufficient space to pivot the plate 1 so far that it lifts the lever 11 and does not hit an edge of the fish tin 2, which is usually a bit with respect to the lid of the Fish tin protrudes upwards.
    The invention has been explained above on the basis of different embodiments and exemplary embodiments. The differently designed or differently arranged opening aids can be transferred to the different embodiments and exchanged as desired.
    In the embodiments and exemplary embodiments explained above, the grip area is formed by a roughened section. Instead of or in addition to the roughened section, the grip area can also have an upwardly protruding fold, in particular along one of the lateral edges 18, which enables simple actuation of the plate.
    chens 1 allowed.
    The plate 1 can be used as a protective cover 1 for an opening of a beverage can. However, there are also embodiments such. B. for the fish box described above, in which the plate 1 is not used to cover an opening.
    The plate 1 can be permanently installed during the manufacture of the can by the rivet reaching through the plate. Within the scope of the invention, however, it is also possible - also in the case of the exemplary embodiment shown in FIG. 5a - to design the plate in such a way that it can subsequently be pushed under the lever of the can. This is shown in Fig. 5b
    wherein the plate with a central edge 7 forms a small recess in order to rest against the rivet 4 with which the lever is attached to the can.
