Abstract: An improved closure for a parenteral solution bottle or the like is disclosed. The closure is of the type having a resilient plug mounted in the bottle neck and a cap anchored to the bottle neck and overlying the periphery of the disc. The cap retains a rigid, malleable disc in position overlying the plug. In accordance with this invention, the rigid, malleable disc defines an annular ridge facing and pressing against the plug to provide a pressure seal.
