Abstract
A tamper-indicating plastic closure is shown which is configured for mechanical interference with the annular locking ring of an associated container. The closure includes a top wall portion and depending skirt portion, with a circular pilfer band at least partially detachably connected to the skirt portion by a plurality of circumferentially spaced fracturable bridges. Notably, the pilfer band includes an internal, annular interference lip which is skewed or arranged at an angle relative to the vertical axis of the closure. By this construction, the interference lip engages the container locking ring during closure application so as to deform the closure to a non-circular configuration, thus minimizing stressing of the fracturable bridges. During closure removal, the angular configuration of the interference lip creates localized stressing of the fracturable bridges, thus providing serial fracture of the bridges.
