Patent ID: 8678220

Claim:
A cap system for a container, comprising: a cap adapted to be coupled to an open top of a container, said cap having a rim lying in a plane, said cap having a hole formed therethrough wherein said hole is adapted to provide fluid communication with an interior region of the container; a closure element coupled to said cap for linear sliding movement with respect thereto, said closure element disposed within the confines of said rim, said closure element defining a solid region and an open region, said closure element disposed at an acute angle with respect to said plane defined by said rim; and at least one weight coupled to said closure element, wherein said closure element and said weight move linearly with respect to said cap as gravity acts on said weight to align at least a portion of said solid region with said hole when said cap is in a first orientation, and wherein said closure element and said weight move linearly with respect to said cap as gravity acts on said weight to align at least a portion of said open region with said hole when said cap is in a second orientation.
