Abstract

This relates to a tamper indicating band which is carried by a plastic closure to indicate that the plastic closure has at least in part been unscrewed with respect to an associated container. It is proposed that the tamper indicating band be directly connected to the closure skirt by way of bridges with the bridges having rupturable connections with the skirt and hinge connections with the tamper indicating band. Thus the tamper indicating band may be folded from its as molded state depending from the skirt to a position projecting upwardly into the lower part of the skirt. When the closure is applied to a conventional type of container, the tamper indicating band locks beneath a locking bead on the container neck finish and when the closure is unthreaded, the engagement of the tamper indicating band with the bead will prevent the tamper indicating band to move upwardly with the closure. As a result, the bridges rupture and the tamper indicating band drops down on the closure neck to indicate that there has been tampering. In one form of the closure, the bridges are twisted 90 degrees from their connection with the skirt to their connection with the tamper indicating band to provide positive rupture points and hinge points. Further, the bridges are elongated so that the lower portion of the tamper indicating band and the applied condition of the closure will be readily visible to indicate to a purchaser that the tamper indicating band exists.
