Abstract
Abstract A container closure apparatus comprises two cooperating lids aligned in juxtaposed relationship. The lower of these two lids incorporates a raised button that protrudes through an opening in the upper lid when the lower lid is in a convex, closed configuration. When in the closed configuration, a drinking orifice region in the lower lid is sealed to the upper lid. Manual depression of the raised button brakes this seal around the driking orifice and causes the lower lid to be in a concave, open configuration. This configuration is maintained by impingement of the uppermost protruding edge of the button against an edge of the upper lid opening. The upper lid is then rotatable about the lower lid and alignment of the upper lid opening with the lower lid drinking orifice allows the pouring of the container''s contents. Realignment of the upper lid opening with the lower surface button and depression and release of the upper lid causes the lower lid to return to the closed, convex configuration.
