Abstract
An improved tamper-evident package includes a plastic closure having a top wall portion, a depending annular skirt portion, and a tamper band at least partially detachably connected to the skirt portion. The package includes a container having a neck portion configured for tamper-indicating cooperation with the projections on the tamper band. The container includes a plurality of circumferentially spaced ratchet-like locking teeth, each of which presents a locking surface for interfering engagement with the respective one of the projections on the closure tamper band. Notably, disposition of the flexible projections of the pilfer band in pre-determined relationship to an internal thread formation of the closure permits the flexible projections to be positioned so that each of the locking teeth on the container is engaged by a respective one of the flexible projections attendant to very little relative rotation of the closure relative to the container during removal.
