Cover for Opening and Closing Cans

摘要

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.

主权项

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; and wherein the top cover component and the bottom cover component are only connected with each other via said spring hook moving within said fastening groove.
