Abstract
A cup lid comprising a base cup lid having a drink-through opening formed therein in a 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 a opening in said rotatable stopper. The base cup lid and the rotatable stopper are mated to one another by the use of convoluted portions on each part which form a sliding tongue and groove relationship. The rotatable stopper has an actuator that can be used to move the rotatable stopper from a closed position wherein the opening in the rotatable stopper and the drink-through opening in the base cup lid, are not aligned, to an open position where the opening in the rotatable stopper and the drink-through opening in the base cup lid, are aligned. An easily operated resealable cup lid is provided.
