Definitions

• CONTAINERS ESPECIALLY BEVERAGE CAN, AND LID FOR SUCH A CONTAINER
• the invention relates to a container, in particular to a beverage can according to the preamble of claim 1 or 37.
• the invention also relates to a container lid or container closure according to the preamble of claim 19 or 40.
• Beverage cans with a can body made of metal, for example made of an aluminum alloy, and with a can lid, which is also made of metal and forms a closure flap on its lid base, which can be pulled out of the lid base to open the can or pressed into the interior of the can, are known and used extensively.
• the disadvantage is that such a container can no longer be closed for further consumption of the container content after opening (use closure).
• the object of the invention is to develop a container or a container closure of the type mentioned in such a way that a convenient and tight use closure is provided, without the need for the user to have to use additional elements that are not already on the lid.
• a container is designed according to the characterizing part of claim 1 or 37 and a container lid or closure according to the characterizing part of claim 19 or 40.
• the container can also be reliably closed after the first opening.
• the rotatable lid element is seen from the top of the lid above the lid element firmly connected to the container body, the bottoms of both lid elements being adjacent to one another.
• the rotatable cover element is located below the cover element firmly connected to the container body inside the container body. In this embodiment, too, the bottoms of the two cover elements lie adjacent to one another.
• the respective rotatable cover element is guided positively on its circumference, but rotatably in the cover element which is fixedly connected to the container body, so that a mutual lifting of the two cover elements from one another is also prevented on the circumference, and thereby in particular in the case of a consumption closure tight closure of the container opening is reached.

• 1 is a beverage can, which is intended for example for soft drinks and has a can body 2 made of metal, for example aluminum or an aluminum alloy by deep drawing, which has a closed peripheral wall and a closed bottom.
• the can body 2 which is open there, is closed by a can lid 3, which is tightly connected to the can body 2 along the edge of the can in the usual manner and with the usual means by folding 4 and hermetically seals the interior of the beverage can 5 from the outside.
• the can lid 3 consists of the lid element 6, which is made from sheet metal, preferably from a sheet of aluminum or an aluminum alloy, by deep-drawing like a cup, with a bottom 7 and with a protruding above the top of the bottom, essentially circular and the container and lid central axis M concentrically surrounding edge 8, which is firmly connected via the fold 4 to the can body 2 or to the edge of the can body surrounding the opening of this can body 2.
• an annular groove 9 which surrounds the central axis M of the can lid 3 in an annular manner is formed in the bottom 7 and is open at the top of the lid base 7, i.e. has its concave side there.
• the cover base 7 Adjacent to the annular groove 9 and offset radially inward with respect to the central axis M, the cover base 7 has an annular bead 10 which likewise concentrically surrounds the central axis M and is convexly curved on the upper side of the cover base 7.
• a closure bottle 11 is also formed, offset radially to the central axis M, which can be pressed inwards in the manner known per se to open the beverage can or the can lid 3, in such a way that when the can is open, the latter Tab 11 is still connected to the lid base 7 in a part of the area into the can interior 5 to release a nozzle opening 11 ′, as shown in FIGS. 4 and 5.
• the tab 1 1 is made in one piece with the cover element 6 or with its bottom 7 in that the edge line of this tab 1 1 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 1 1 is reinforced by a self-contained ring-like reinforcing bead 12 which projects beyond the plane of the tab 11 or above the top of the base 7.
• a break-open ring 13 provided on the top of the can lid 3 serves to break open and inwardly bend the tab 11, which in a known manner in the top view of FIGS. 1 and 3 serves as an oval ring 14 with a central web 15 and two on both sides of the central web 15 formed ring openings 16 and 17 is executed.
• a flap 18 extends, with which the rupture ring 13 is fastened to the top of the cover element 6 in the region of the central axis M, namely by means of a material made from the cover base 7 shaped rivet-like fastening section 19.
• the ring body 14 and the central web 15 are rigid.
• the tab 18 is bendable.
• the side facing away from the ring opening 16 is the rupture ring or its ring body 14 against the sealing flap 11 or the bead 12 there.
• the rupture ring lies with its ring plane parallel or approximately parallel to the plane of the lid base, within the of the space 8 enclosed space, ie below the upper edge of the beverage can 1 formed by the fold 4.
• a further cover element 20 is provided on the fastening section 19 between the container base 7 and the tab 18 so as to be rotatable about the central axis M.
• this cover element 20 is designed in the form of a circular disk and has a rolled-up, closed edge bead 21 which surrounds the central axis M in a circular shape. With the closed, rolled-up edge bead 21, the cover element 20 is guided in the annular groove 9.
• the edge 8 are in several areas distributed around the central axis M, ie in the illustrated embodiment in six areas distributed around the central axis M. Pressed in cams 22 which protrude beyond the inside of the edge facing the bottom 7 and hold the edge 21 in the annular groove 9.
• the cover element 20 is also slightly cup-shaped, i.e. it has an essentially circular disk-shaped base 23, an annular edge 24 which extends obliquely downwards into the annular groove 9 and surrounds the central axis M and which has the edge bead 21. At the transition between the edge 24 and the bottom 23, an annular bead 25 is formed, which likewise surrounds the central axis M and causes an additional stiffening of the cover element 20.
• an opening 26 is provided in the bottom 23 of the lid element 20, which has at least the same dimensions as the closure tab 11 or the drinking or pouring opening 11 formed after the closure tab has been pressed in. When the box 1 is originally closed, the opening 26 is congruent with the closure flap 11.
• the bead 12 is located within the opening 26 and extends into this opening 26, so that twisting of the cover element 20 relative to the cover element 6 is not possible.
• the bottom of the lid base 23 bears against the annular bead 10 of the lid base 7.
• a gap is formed between the two cover bottoms 7 and 23, the width of which is approximately equal to the thickness of the seal 27 clamped elastically between the two trays 7 and 23, that is to say, by the abutment of the cover base 23 against the annular bead 10, it is also prevented that the seal 27 is deformed too much by appropriate riveting in the region of the fastening section 19 and is thereby destroyed.
• Two drivers 28 protruding from the top of this lid bottom are formed on the lid bottom 23.
• the cover element 20 with all its components is made in one piece from the metal sheet by stamping and shaping.
• the break-open ring 13 and all parts of the lid elements 26 are designed and arranged in such a way that there is sufficient free space on the inside of the can lid 3 in order to be able to process it with the usual machines for closing the can body 2.
• Figures 1 and 2 show the beverage can 1 in the original closed state.
• the break-open ring 13 is raised on its side remote from the closure tab 11 in accordance with the arrow A in FIG. 2, as a result of which the other side of the break-up ring comes to rest against the closure tab 11 or the bead 12 there, and thereby the closure tab 1 1 pressed inwards and the opening 1 1 'is created ( Figure 4).
• the contents of the beverage can 1 can be poured out or drunk through the openings 11 'and 26 which then overlap.
• the beverage can 1 can be closed during use.
• the cover element 20 is rotated on the drivers 28 so far about the central axis M that the opening 26 is outside the opening 11 * and the latter is covered by the cover base 23.
• the cover element 20 is rotated through 180 °.
• the two end positions are defined by stops 29 and 30 (FIG. 6) formed in the annular groove 9 and on the edge or annular bead 21.
• the break-open ring 13 is also connected to the cover element 20 in a rotationally secure manner, namely by the fact that the rectangular-shaped tab 18 in one of these tabs suitably receiving recess is received in the lid base 23.
• a seal is achieved by the seal 27, especially since the cover element 20 is reliably guided in its circumference by the cams 22 in the annular groove 9 and by the against the wrist 21 adjacent cam 22 is also secured against undesired lifting off at the edge, so that lifting of the consumption closure is not to be feared even with carbonated drinks under pressure.
• FIGS. 7 and the following show a beverage can la, which in turn consists of the can body 2 and a can lid 3a closing it on the upper side, which differs from the can lid 3 essentially in that the lid element 31 firmly connected to the can body forms the upper lid element and the cover element 32 which can be rotated for the consumption closure, the lower, ie in the interior 5 of the beverage can arranged lid element.
• the cover element 31 is again cup-shaped with an essentially circular disc-shaped cover base 33 and a cover edge 34 which is connected to the edge of the can body 2 via the fold 4. At the transition between the lid base 33 and the edge 34 is on the lid element 31 with a circularly enclosing the central axis M and in the interior 5, i.e. Provide over the underside of the bottom 33 projecting annular bead 35 surrounding the central axis M.
• the cover element 31 also has an opening 26 at the bottom 33 corresponding to the opening 36.

• the cover element 32 is rotatably supported in the middle of the cover element 31.
• the cover element 32 is shaped on its annular edge 37 in such a way that it engages around the annular bead 35 in a form-fitting manner, but at the same time also forms a guide for the cover element 32 when rotating about the central axis M.
• the closure flap 11 is formed with the bead 12, which extends into the opening 36 in the original closed beverage can la and thereby prevents the cover element 32 from rotating relative to the cover element 31 about the central axis M.
• the seal 27 surrounding the closure flap 11 is again provided.
• the break-open ring 13 is in turn raised on its side remote from the opening 36 (arrow A in FIG. 8), the closure tab 11 is broken through the opening 36 and pressed into the interior 5, so that through the then covering openings 36 and 11 '(FIG. 10) of the can contents can be removed.
