Abstract:
A dispensing stopper for a bottle comprising:a stopper base adapted to be mounted on the mouth of a bottle;a unitary seal of elastomer mounted on said base, said seal including a fixed section fixed to said base, a movable gasket section movable toward and away from said stopper base and away and toward a sealing surface about the mouth on a bottle to which said base is mounted, and a thin, web of resilient material interconnecting and sealing said fixed section and said movable gasket section;an actuator attachment section affixed to said movable gasket section, and including a valve surface adapted to seal about the mouth of a bottle;said movable gasket section including a radially inward opening groove and said actuator attachment section including two spaced radially outwardly directed peripheral edges, a first of said edges being received in said groove and the other of said edges defining the periphery of said valve surface; anda lever pivoted to said base and to said actuator section at spaced locations;whereby application of a pivoting force to said lever will move said gasket section toward said fixed section to move said gasket section away from the mouth of a bottle on which said base is mounted and the absence of said force will allow the resiliency of said web to return said gasket section toward the mouth of a bottle on which said base is mounted.
