Abstract: A penetrator for penetrating a stopper sealing an opening in a container. The penetrator includes a stamped piece of sheet material formed to define a shank having a length. A groove extends along the length of the shank. The shank has a pointed distal. The stamped piece of sheet material further includes a bearing plate extending from the shank at a proximal end opposite the distal end of the shank.

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.

Abstract: A closure is provided for mounting across the mouth of a container and through which liquid can be withdrawn with a fluid transfer device having a male member. The closure includes a body for being disposed on the container across the container mouth. The body defines a passage with an exterior opening for matingly receiving the male member of the fluid transfer device. A frangible seal initially extends across the passage in the body to occlude the passage. The seal is broken when it is engaged by the male member of the fluid transfer device, thereby establishing fluid communication between the fluid transfer device and the interior of the container.
