ABSTRACT:
The disposable lid for a coffee cup or the like has penetrable score lines around the sides of a 90.degree. sectorial portion thereof for easily breaking off this portion to form a drinking access opening therethrough while the remaining portion of the lid serves to reduce the danger of spilling the contents of the cup when held in an unsteady cup support environment. Another penetrable score line extending near the periphery of the lid, between the sides of this sector, and a fold score line between the ends of this peripheral score line provide for a segmental flap to be broken open and bent on the fold score line to form an access opening to the contents of the cup while providing a substantial shield against spilling the contents of the cup through the opening.
