Abstract
A tamper indicating closure and closure-container package in which a tamper indicating skirt depends from the bottom of the annular wall of a standard threaded cap. The skirt includes a plurality of equally spaced depending ribs which are joined at their extremities by a flexible ring. The ring and the skirt ribs pass over lugs on the container neck when the cap is being threaded onto the closure. When the cap is being unthreaded, the lugs engage the rings to sever them indicating tampering or prior opening.
