The invention relates to a cover for opening and closing cans, in particular beverage cans, having a top circular cover component and a bottom cover component. By moving the two cover components relative to one another, at least one through-hole can be opened and re-closed by both cover components.
The invention relates to a cover for opening and closing cans, in particular beverage cans, having a top circular cover component and a bottom cover component. By moving the two cover components relative to one another, at least one through-hole can be opened and re-closed by both cover components. A highly effective seal is obtained by precise coordination of the form of the top and bottom cover components, which can be increased even further by the additional use of sealing materials such as varnish, rubber, plastic or welded connections.

1. A cover for opening and closing beverage cans, comprising: a top cover component with an opening therein and a radially outermost end;a bottom cover component with an opening therein, said top cover component rotatably mounted on said bottom cover component, wherein said openings in said top cover component and said bottom cover component align to define a through-hole through said cover by rotation of said top cover component relative to said bottom cover component, said through hole closed by further rotation of said top cover component relative to said bottom cover component;said bottom cover component comprising an at least partially circular and concave fastening groove defined on a top side thereof, said fastening groove having an open end oriented radially outward and a closed end extending radially inward relative to an outer radius of said bottom cover component;said top cover component comprising a spring hook with a distal end disposed radially inward of said radially outermost end of said top cover component, said fastening groove disposed radially inward of said distal end such that said distal end extends radially inward into said open end of said fastening groove and engages against said bottom cover component at said closed end within said fastening groove, said spring hook moving within said fastening groove when said top cover component is rotated relative to said bottom cover component; andwherein the top cover component and the bottom cover component are only connected with each other via said spring hook moving within said fastening groove. 2. The cover as in claim 1, wherein said fastening groove is disposed below a level of said opening in said bottom cover component and above a lowermost level of said bottom cover component. 3. The cover as in claim 1, wherein said bottom cover component comprises an elevation that engages against and lifts said top cover component relative to said bottom cover component when said top cover component is rotated relative to said bottom cover component. 4. The cover as in claim 1, wherein said top cover component and said bottom cover component are made of one or more of aluminum, plastic, or sheet metal. 5. The cover as in claim 1, wherein said top cover component comprises an open recess. 6. The cover as in claim 5, wherein said recess is defined as a circular segment in said top cover component. 7. The cover as in claim 1, wherein said top cover component comprises two radially opposite open circular segment recesses defined therein, and two radially opposite circular material segments, said spring hook defined at radial edges of said two circular material segments. 8. The cover as in claim 7, wherein said top cover component further comprises wings in a central area between said radially opposite circular material segments, said wings configured for grasping and rotating said top cover component. 9. The cover as in claim 1, further comprising a sealing surface around said opening in said bottom cover component, said sealing surface pressed directly against said top cover component in a rotated position of said top cover component that closes said through-hole. 10. The cover as in claim 9, wherein said bottom cover component extends in a cover level below said top cover component, said sealing surface disposed below said cover level. 11. The cover as in claim 10, wherein said sealing surface comprises a sealing edge that is angled radially inward and downward. 12. The cover as in claim 1, further comprising a breakable seal configured between said aligned openings in said top and bottom cover components. 13. The cover as in claim 12, wherein said breakable seal comprises a seal member that engages into said opening in said bottom cover component. 14. The cover as in claim 13, wherein said seal member is attached to said top cover component. 15. The cover as in claim 1, wherein at least one of said top or bottom cover components is made from a hybrid laminate material having a plastic layer. 16. The cover as in claim 15, wherein each of said top and bottom cover components are made from the hybrid laminate material, wherein the respective plastic layer of said top and bottom cover components are facing. 17. The cover as in claim 1, wherein said opening in said bottom cover component comprises an angled inner edge, said top cover component comprising a cone-like projection that engages against said angled inner edge in the closed rotational position of said top cover component relative to said bottom cover component. 18. The cover as in claim 17, wherein said top cover component comprises a raised elevation section, said cone-like projection defined in and extending downwardly from said elevation section such that a sealed engagement between said cone-like projection and said angled inner edge of lies in a plane below said elevation section. 19. A beverage can, comprising: a cylindrical body;a cover mounted onto said body, said cover further comprising:a top cover component with an opening therein and a radially outermost end; a bottom cover component with an opening therein, said top cover component rotatably mounted on said bottom cover component, wherein said openings in said top cover component and said bottom cover component align to define a through-hole through said cover by rotation of said top cover component relative to said bottom cover component, said through hole closed by further rotation of said top cover component relative to said bottom cover component; said bottom cover component comprising an at least partially circular and concave fastening groove defined on a top side thereof, said fastening groove having an open end oriented radially outward and a closed end extending radially inward relative to an outer radius of said bottom cover component;said top cover component comprising a spring hook with a distal end disposed radially inward of said radially outermost end of said top cover component, said fastening groove disposed radially inward of said distal end such that said distal end extends radially inward into said open end of said fastening groove and engages against said bottom cover component at said closed end within said fastening groove, said spring hook moving within said fastening groove when said top cover component is rotated relative to said bottom cover component; andwherein the top cover component and the bottom cover component are only connected with each other via said spring hook moving within said fastening groove.
