Threaded closure with tamper indicating ring

Abstract

A threaded closure for containers having a tamper indicating ring frangibly interconnected to a lower edge of a side wall of the closure. The ring includes tabs engaging a bead on the neck of the container in which the tab extends axially above the frangible parting line interconnecting the ring and the side wall of the closure prior to the first removal of the closure from the neck of the container. The tabs include an inwardly directed rib or projection forming a shoulder or notch which engages the edge of the closure bead, when the closure is first removed.
