Universal closure assembly designed for use in various containers having a fluid port for access to the content of the container. The universal closure assembly incorporates an elastomeric membrane capable of being ruptured by an access means such as a luer connector or a syringe having a sharp or blunt cannula or a sharp or blunt spike for fluid communication between the content of the container and the access means. The elastomeric membrane reseals itself after being ruptured by an access means.

[ What is claimed is:] [1.] A universal closure assembly and a container combination, said combination comprising:(a) a container;(b) a closure assembly; and(c) a removable cap covering said closure assembly; reinsaid container (a), containing a medical fluid therein, having a neck portion terminating in an open end;said closure assembly (b), inserted into the open end of said container comprises:(1) an elastomeric stopper for hermetically sealing the container at its open end comprising:a head portion;a skirt portion;a cylindrical opening in a center portion of said head and skirt portions;a hollow, vertically oriented thin elastomeric protuberance serving as a diaphragm for sealing the opening in the center portion of the elastomeric stopper designed to be ruptured by an external force, said elastomeric protuberance having a generally M-shaped configuration comprising: a flat, horizontal base open in its center portion; cylindrical side walls extending from the flat, horizontal base to the top surface of said stopper; a cup-shaped portion extending downwards from the top of the cylindrical walls, said cup-shaped portion having a slit in its center portion extending towards the content of the container without traversing said diaphragm;(2) a rigid, cylindrical housing having open ends enclosing said vertically oriented thin elastomeric protuberance to support said vertically oriented thin elastomeric protuberance and to serve as means for receiving and engaging a female luer connector whereby an external force moves the female luer connector which penetrates the thin elastomeric protuberance to establish fluid communication with the medical fluid contained in said container, said rigid cylindrical housing comprising: cylindrical walls having a top portion and a bottom portion, said top portion having locking ears designed to hold the female element of the luer connector, and said bottom portion sealed in the skirt portion of the elastomeric stopper;(3) a cylindrical collar fastened over a portion of the elastomeric stopper and neck portion of the container to securely hold the elastomeric stopper in the open end of the container, said cylindrical collar having a central opening in its float top portion to allow access to the elastomeric protuberance and the rigid cylindrical housing located in the center portion of said elastomeric stopper; andsaid removable cap (c) covering the flat top and rim portions of said cylindrical collar comprising retaining ears engaging said cylindrical collar to maintain said closure assembly in aseptic condition.
