CUP AND LID USING MAGNETIC-BASED SPILL-PROOF SEAL

摘要

A cup/lid combination includes a sleeve disposed about an exterior surface of an open-top container for movement relative to the container. A first magnet is disposed adjacent to the open top for movement relative to the container. A link assembly coupled to the sleeve and to the first magnet causes the movement of the sleeve and the movement of the first magnet to be in opposing directions. A drinking lid disposed on the open top has a gravity-controlled closure element and a second magnet coupled to the closure element. The first and second magnets are positioned for magnetic interaction to thereby fix a position of the closure element when the sleeve is only subject to the force of gravity. The first and second magnets are positioned for no magnetic interaction when the movement of the sleeve opposes the force of gravity.

主权项

1. A cup and lid combination, comprising:
a liquid-holding container having an open top; a sleeve disposed about an exterior surface of said container for movement relative to said container; a first magnet disposed adjacent to said open top of said container for movement relative to said container; a link assembly coupled to said sleeve and to said first magnet for causing said movement of said sleeve and said movement of said first magnet to be in opposing directions; and a drinking lid disposed on said open top of said container, said drinking lid having a gravity-controlled closure element and a second magnet coupled to said closure element, said first magnet and said second magnet being positioned for magnetic interaction to thereby fix a position of said closure element when said sleeve is only subject to the force of gravity, and said first magnet and said second magnet being positioned for no magnetic interaction when said movement of said sleeve opposes the force of gravity.
