TAMPER-EVIDENT CLOSURE CAP CONSTRUCTION Abstract A tamper-evident plastic closure cap construction which is intended to provide to the consumer a distinc- tive visual alerting indication in the event that the container has been previously opened or tampered with, comprising a closure portion and a base portion, the latter being snapped into position on the container and held permanently thereon by means of cooperable retainer shoulders. The closure portion seals off the dispensing orifice of the container in a usual manner. Joining the closure portion to the base portion are multiple fran- gible webs associated with an indicator ring which nor- mally occupies a first or depressed position prior to opening of the container. When the closure portion is initially turned or otherwise disturbed, the frangible webs break, and their resilience causes the ring to shift laterally by a significant amount to a second or raised position, which attracts the attention of one handling the container. The advantage of the improved construction over many of the devices of the prior art is that the ring provides a more pronounced indica- tion of possible tampering than all previous construc- tions which depended solely on breakage of one or more relatively small webs, to reveal tampering.
