Valved receptacle closure

A valved closure for a disposable drinking receptacle comprising a cover having a peripheral edge for sealingly engaging a receptacle rim, said cover being formed of a thin synthetic plastic of substantially uniform thickness, said cover having a recess integrally formed therein, a drinking opening in said cover disposed in said recess adjacent the edge of said cover, said recess having grooves therearound, a slide valve disposed in said recess and having edges coacting with said grooves for slidable movement of said slide valve between a first position closing said drinking opening and a second position exposing said drinking opening, and resilient means operatively associated with said slide valve for urging said slide valve into said second position and latch means for releasably securing said slide valve in said first position, said latch means comprising a resilient cantilever member having a free end and connected to said slide valve, said latch means being actuable to release said slide valve by application of a linear force to the free end of said cantilever member.

A valved closure for a drinking receptacle having a rim comprising a cover adapted to engage the rim of the drinking receptacle, a drinking opening disposed in said cover, valve means cooperating with said cover and movable in a plane between a first position closing said opening and a second position exposing said opening, resilient means cooperating with said valve means for urging said valve means into said second position, finger-actuable means for moving said valve means into said first position against the force of said resilient means and latch means operatively connected to said valve means for releasably securing said valve means in said first position against the force of said resilient means, said latch means being releasable by a linear force applied to said latch means in a direction substantially normal to the plane of movement of said valve means.

A closure adapted to be mounted in a cover of a fluent material receptacle, said cover having an opening which communicates with the fluent material in the receptacle, said closure comprising valve means movable from a first position closing said opening to a second position exposing said opening, mounting means on said cover for slidably engaging said valve means with respect to said cover, resilient means for urging said valve means into one of said positions, and latch means operatively connected to said valve means for releasably securing said valve means in the other of said positions against the force of said resilient means, said latch means comprising a resilient cantilever member having a free end releasable by application of a linear force to said free end.
