Abstract
A medication container stopper includes an elastomeric plug which makes a friction fit in an opening of the container. A first cavity in an exterior surface of the plug opens and diverges away from an interior surface of the plug. A second cavity opens qnd diverges away from the exterior surface of the plug. The bottoms of the cavities are spaced apart to define opposite faces of a thin diaphragm formed integrally with the plug. One of the cavities has an elongated groove with a bottom which defines one face of the diaphragm, which is of a thickness that permits the diaphragm to be ruptured by inserting a conventional hypodermic syringe nozzle into the cavity in the exterior surface of the plug.
