ABSTRACT:
The present invention relates to a tamper-evident container having a threaded neck to receive a threaded closure having a tamper evident feature. The container has a tamper-evident feature bead for retaining the feature on the container. The bead has one or more outwardly and downwardly shaped bulges which, as the closure is twisted off, apply a localized rupturing force on the tamper-evident feature so as to tear the feature away from the closure.
