Abstract
A container closure comprises a cylindrical molded utitary member defining a top panel and a skirt depending from the top panel to an open end for securement to the container, the skirt being interiorly tapered at the open end. The taper begins flush with the outer surface of the skirt and ends in a first circumference radially of the central axis of such cylinder. The skirt further defines a bead extending radially interiorly of the skirt to a second circumference radially closer to the cylinder central axis than the first circumference. The closure provides sealing retention pressure in accordance with the radially interior extent of the bead and exhibits evidence of initial removal from the container. The method for making the closure involves the use of a stripper plate to participate in part in defining a mold cavity.
