Abstract
A cap assembly for a container has a hollow housing with an upper end that receives a fluid transfer device and a lower end that engages a stopper on the container. The housing has an internal cavity open at the upper and lower ends and a radially outwardly extending portion at the lower end. A penetrator is received in the internal cavity. The penetrator has a pointed distal end opposite the stopper and an upper end constructed to be engaged by a fluid transfer device. A cap is constructed the hollow housing. The cap has a closed upper end, an open lower end, a radially outwardly extending portion at the open end, and a circumferential line of weakness connecting the upper and lower ends. A ferrule is over the radially outwardly extending portion of the hollow housing and the radially outwardly extending portion of the cap.
