Abstract
A plastic closure includes an annular ring durably attached to the container, and a sealing assembly installed in the ring to seal the mouth. The sealing assembly includes a plug having a sealing lip on its lower face and a release lever connected to the plug by a flexible hinge. A tab on the release lever can be lifted to pry the sealing assembly out of the opening. The ring has a free edge directed downwardly and inwardly so as to permit the plug to pass easily through the opening during assembly, or resealing, but to resist removal of the plug sufficiently to prevent it from being forced off the container by pressure within the container.
