Patent ID: 7594584

Claim:
A cup lid comprising a base cup lid having a drink-through opening formed therein in a first planar top portion thereof, and a rotatable stopper associated therewith so as to selectively provide a sealed and unsealed relationship between said drink-through opening and said rotatable stopper; wherein said rotatable stopper has a first planar portion, a second convoluted portion, a third planar portion, and a centrally located actuating portion having an actuator formed therein; wherein an opening is formed in said first planar portion of said rotatable stopper so that when rotated to be in alignment with said drink through opening, a liquid passage is provided through said opening in said rotatable stopper and through said drink-through opening in said base cup lid; wherein said base cup lid has a second convoluted portion below said first planar top portion, and a third planar portion below said second convoluted portion; wherein said second convoluted portions of both said base cup lid and said rotatable stopper are dimensioned so that a slidable and rotatable relationship between them is achieved when they are assembled together with said first planar portion of said rotatable stopper being below said first planar top portion of said base cup lid; and whereby when said base cup lid and said rotatable stopper are assembled one to the other so as to have a rotatable and sliding relationship therebetween, said drink-through opening in said base cup lid is selectively sealable and unsealable by rotation of said rotatable stopper.
