Abstract
A tamper evident closure assembly comprising a container, a cap and a band portion. The container has a neck with threads and an annular interference ring located axially below the threads and integral with the container finish. An annular tamper indicating band is detachably connected to the skirt of the cap with a plurality of spaced connectors located between the cap and the band. The band has an annular shoulder formed on the inside surface thereof. The interference ring includes at least one integral lug formed on its upper surface. The lug is configured with a downwardly sloping upper surface and a substantially vertical face. The sloping upper surface of the lug facilitates the application of the closure, and specifically the band, over the interference ring. The face of the lug forms a strengthening support against which the annular shoulder of the band rests.
