Abstract
A cap assembly is provided for mounting over the mouth of a container which is occluded with a stopper. The cap assembly includes a housing, a moveable piercing member or penetrator within the housing, a removable overcap over the housing, and a ferrule connecting the housing to the container. A preferred form of the penetrator is fabricated from sheet metal in a progressive die stamping process. One form of the overcap includes a frangible construction that permits the upper part of the overcap to be torn away to expose the upper portion of the housing.
