发明名称 Tamper resistant closure with tear-off band
摘要 A tamper resistant closure for a finish of a container. The closure has an annular skirt with an annular tamper indicating band integrally attached thereto with a plurality of frangible bridges. The band has preferably a plurality of wedge-shaped tabs that contact the container finish and bend upwardly when the closure is applied to the container. When there is an attempt to remove the closure, the thicker outer portion of the tab wedges against the container finish to apply torque to the band and break the bridges to leave the pilfer indicating band on the container.
