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 linkage. The tab on the release lever can be lifted to pry the sealing assembly out of the opening. The lever comprises more than one hook protruding downwardly, connected to the outer edge of the lever by frangible bridges or by a frangible line. The hook is engageable with retaining elements attached to the attachment ring or to the container. The frangible bridges or the frangible line are constructed to break during first opening of the closure, to provide an indication that tampering has occurred.
