Abstract

A tamper-evident closure and container are provided which includes a threaded closure and tamper-indicating features. The features have upwardly an inwardly folded tabs which lock against the lower surface of an annular shoulder on a container neck to retain tamper-indicating features on the neck as the closure is removed. The tamper-indicating features include a pilfer ring to which the tabs are integrally connected. The tabs are resilient and are fixed by the container finish at the joints where they are joined to the pilfer ring. The closure of the present invention may be installed simply by screwing it onto a container neck in a one-step process. The flexible tabs assist in guiding the closure and centering it when installed onto the container neck and do not require the holding of the closure or the container finish to close tolerances in order to be consistently effective. A thin web of material is provided between the tabs which prevents the outward bending of the tabs which may occur during shipping or handling.
