Claim:
A plastic drink-through lid for an open top drink cup with a rim, said lid being of the type generally having a deck portion, an integral rim engaging skirt; the improvement comprising a preformed, at least partially separated, fold-back tab formed within the deck adjacent but spaced in its entirety from the skirt to create a drink-through opening in the deck when folded back; a preformed hinge in the deck extending along the interior edge of the tab; the hinge lying sufficiently close to the peripheral skirt that the tab, when folded back, lies entirely on one side of the lid center; an upstanding thumb catch having inner and outer exterior surfaces formed integrally with the tab and extruding upwardly therefrom to a height which is higher than the deck, the lid being free of raised structural features between the skirt and the outer surface of the catch, a recess formed in the deck inwardly adjacent the hinge to receive the catch therein when the tab is folded back; and said outer surface having upper and lower portions, a horizontal ridge formed on the upper portion and extending radially outwardly beyond the lower portion to assist in the manual engagement of the catch and to retain the catch in the recess.
