Image Number 2 for United States Patent #6557714.

A 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 further 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 a respective one of the projections of the closure tamper band. The arrangement is particularly configured to promote rapid tamper-indication attendant to relatively little rotation of the closure relative to the container.
