Abstract
A tamper evident closure preferably for use on a screw threaded neck of a container is disclosed. The closure includes a tamper evident band which is quite thin and has a diameter which approximates that of the cap's sidewall. The tamper evident band is joined to the cap's sidewall by a plurality of bridge strips that are circumferentially aligned with ratchet teeth on the tamper evident band. During application of the cap to the container neck, the band deforms as the ratchet teeth cam over cooperatively shaped ratchet lugs on the bottle neck. However, during cap removal, the ratchet lugs stop the ratchet teeth and the tamper evident band from moving so that the band is separated from the cap thereby providing a clear indication of tampering with the closure.
