ABSTRACT:
A tamper indicating container and container-closure package in which the tamper indicating band is integrally molded on the container neck with connecting frangible webs. The tamper indicating band has circumferentially spaced pawls on its top which co-act with a circumferential array of ratchet teeth at the lower end of the closure cap skirt to prevent removal of the cap upon application of opening torque without fracture of the frangible webs indicating tampering or initial opening. The closure of the container-closure package includes a cap skirt having a wall portion which recesses the cap ratchet teeth and overlaps the tamper indicating band of the container so as to keep the ratchet locking mechanism out of the view of a person endeavoring to tamper with the package.
