A drink-through cup lid, adapted to matingly engage the upper peripheral edge of a drinking cup so as to selectively maintain the lid in a covering relationship on the cup, includes a rim engaging portion and a central cover portion. The central cover portion further has a hinged portion which is selectively depressible to so as to provide a drinking opening in the lid, the hinged portion is biased so as to selectively substantially return to its normally closed position within the plane of the central cover portion upon removal of pressure there-against. The hinged portion includes a hollow raised tab integrally formed thereon. A recess which is integrally formed on the central cover portion of the lid is adapted to selectively receive the raised tab of the hinged portion in detachable locking engagement.
