ABSTRACT:
A disposable cup lid is substantially circular, and has a downwardly facing cup rim engaging recess extending from 300.degree. to 360.degree. around the periphery. The recess is defined at its outer side by a downwardly depending apron, at its inner side by a downwardly directed recess sidewall, and at its top by a top wall between the apron and the recess sidewall. The apron extends 360.degree. around the periphery. An arcuate portion of the top surface extends radially outwardly to the apron, and has a radially directed axis of symmetry. A depressed "U"-shaped hinge is formed in the arcuate portion, and is oriented so as to be perpendicular to the axis of symmetry. A fault line is stamped into the the arcuate portion, in a location opposed to the "U"-shaped hinge, and is spaced radially inwardly from the apron by a distance which is at least equal to the width of the top wall of the cup rim engaging recess. The fault line defines an outer extremity of a tear-back flap which, when torn back, will fold backwardly at the "U"-shaped hinge so as to define a drink-through opening. An upwardly extending lifting stub is formed in the arcuate portion of the top surface, and is such that it may be easily grasped between the thumb and a finger of an adult hand, so that it may be torn back by grasping and lifting the stub, and so as to provide access to the drink-through opening.
