TAMPERPROOF CLOSURE CAP AND SEALED PACKAGE

摘要

A closure cap for threaded containers is described which includes a tamperproofing means to indicate unauthorized tampering with or removal of the closure cap from the sealed container. The closure cap is of composite construction having a metal disc-like top fitted into a molded plastic ring or skirt. The plastic skirt includes container engaging threads positioned above a tear-off tamper indicating band. The tamper indicating band has integral molded pawl members which engage lugs or ratchet teeth on the container so that the tamperproofing strip must be removed before the closure cap can be turned off of the container. Should there be an unauthorized attempt to open the container, the tamperproofing strip will be torn off as the closure is turned on the container.
