ABSTRACT:
A thin, plastic lid for disposable drinking cups has a drinking opening formed in a raised portion of the lid. The drinking opening is covered by a hinged closure member that is locked in place by trapping an outer marginal edge of the closure member between the cup rim and the periphery of the lid. The lid may be formed by conventional vacuum forming and die cutting operations.
