Abstract
Abstract This relates to a plastic fitment to be utilized in conjunction with a conventional metal closure having a rotational engagement with threads on a container neck finish. The fitment has a readily engageable snap-in interlock with the closure and is provided with a tamper indicating band attached to a ring thereof by rupturable bridges. When the closure and fitment are applied to a container, the tamper indicating band will ride over and lock behind a projecting rib on the closure neck finish. When the closure is to be removed, as it moves axially the bridges will rupture leaving the tamper indicating band on the container while the ring of the fitment is removed with the closure. If desired, a customer may remove the ring from the closure and reseal the container with the closure per se.
