发明名称 TAMPER-PROOF CLOSURE
摘要 A tamper-proof closure, for a container, which requires removal of a tamper-proof ring before the container may be opened. The closure of the present invention includes a closure body which is threadably engaged with the finish portion of a container. A split tamper-proof ring is attached to the closure body at a plurality of severable locations at the root portion of a plurality of projections formed on the interior of the tamper-proof ring. A severable bridge extends between the opposed free ends of the split tamper-proof ring and connects them. The container has a series of external projections located below the threads of the finish portion. The projections of the tamper-proof ring lock with the projections on the container to prevent removal of the closure body. To remove the closure, the severable bridge is broken and the resulting free end of the tamper-proof ring is used as a pull tab to break the connections between the closure body and the tamper-proof ring.
