ABSTRACT:
A two-level tamper-evident system for molded plastic container closure combinations. The closure is of the type which has an inexpandable peripheral skirt which snaps over and locks onto the container lip and which must be broken at several fracture points before it can be removed. In addition a tear strip acts as a removable barrier to the fracture points. As such, it must be received before the closure can be removed.
