ABSTRACT:
A snap-on plastic closure for a container includes a top wall portion, an annular skirt portion depending from the top wall portion, and a removal tab projecting forwardly from the skirt portion for manipulation of the closure during removal. A sealing plug depends from the inside surface of the top wall portion for disposition generally within the mouth of an associated container. The skirt portion of the closure includes a deformable region positioned beneath the removal tab so that during closure removal, the deformable region is permanently stretched and deformed for tamper-indication.
