Abstract
A molded plastic lid of the drink-through type for use in connection with a conventional beverage cup. The lid exhibits a cup engaging rim and, radially inwardly thereof, a raised crown portion having a side wall and a top. The top is generally flat but has formed therein a centrally located recess, the floor of which extends laterally to the side walls and which is at all times above the maximum fill line of the cup during normal operation. The recess exhibits a structure which may be depressed into a stable inverted condition which provides an enlarged drink-through aperture immediately adjacent the side wall.
Claims4
A drink-through lid for beverage cups of the type having a circular lip comprising:
- an annular rim portion adapted to conform to and sealingly engage the cup lip;
- a raised crown portion contiguously inward of said annular rim, said crown portion having a continuous peripheral side wall and a top;
- and
- drink-through aperture means providing an opening in said lid, said aperture means formed in said lid adjacent said side wall and comprising an integral structure which normally assumes a convex shape above the annular rim, but which is deformable into a concave shape above the annular rim and partially separated from the side wall immediately adjacent the side wall.

- an annular rim portion adapted to conform to and sealingly engage the cup lip;
- a raised crown portion contiguously inward of said rim portion, said crown portion having a continuous peripheral circular side wall and a top;
- a collector recess formed generally centrally of said top and defining a recess floor which lies substantially below said top but above the annular rim;
- said collector recess having a lateral extension with upwardly extending opposite walls which run essentially to said side wall and define an extension floor between said walls at least approximately co-planar with said recess floor;
- and
- drink-through aperture means providing an opening in said lid, said aperture means formed in said lid adjacent said side wall and comprising an integral structure which normally assumes a convex shape above the recess floor, but which is deformable into a concave shape below the recess floor, but above the annular rim and partially separated from the side wall immediately adjacent the side wall.
