Abstract
A threaded one piece closure having a tamper indicating ring attached to the lower end of the cap skirt by shear webs which fracture upon the initial opening of the closure leaving the detached ring on the container indicating the initial opening or tampering. The inner surface of the ring has a retaining bead which engages an annular flange on the container which restrains movement of the ring in the opening process. Cooperating drive means on the cap skirt and ring allow initial closure application to the container without fracture of the shear webs.
