A disposable cup lid is provided for placement onto a drinking cup having a substantially circular cup rim which lies substantially in a single plane. The cup lid comprises a substantially circular and substantially planar top surface, and a downwardly facing cup rim engaging recess formed near the outer periphery thereof. The cup rim engaging recess extends from 300° to 360° around the periphery, and is defined at its outer side by a substantially circular, downwardly depending apron, at its inner side by a first downwardly directed recess sidewall, and at its top by a top wall between the downwardly depending apron and the downwardly directed recess sidewall. The downwardly depending apron extends 360° around the periphery. There is an arcuate portion of the top surface which extends radially outwardly to the downwardly depending apron, and which has a radially directed axis of symmetry. A depressed "U"-shaped hinge is formed in the top surface in the region thereof occupied by the arcuate portion, and the "U"-shaped hinge is oriented so as to be perpendicular to the axis of symmetry. A fault line is stamped into the top surface in the arcuate portion, in a location opposed to the "U"-shaped hinge. The fault line is spaced radially inwardly from the downwardly directed apron by a distance which is at least equal to the width of the top wall of the cup rim engaging recess; and the fault line defines an outer extremity of a tear-back flap which, when torn back, will fold backwardly at the "U"- shaped hinge and will thereby define a drink-through opening in the top surface. Also, an upwardly extending lifting stub is formed in the arcuate portion of the top surface in a location thereof between the first fault line and the "U"-shaped hinge. The dimensions of the lifting stub are such that it may be easily grasped between the thumb and a forger of an adult hand, so that the tear-back flap may be torn back by a grasping and lifting action of the lifting stub, and so as to provide access to the drink-through opening.
