Abstract: An improvement in a fluid flow valve is disclosed. The valve comprises a combination of flexible tubing joined to a tubular member having a membrane closing off the passageway in the tubular member. A pointed spike having at least three radially projecting ribs extending longitudinally is located within the tubing adjacent the membrane and is movable by external manipulation of the tubing whereby the spike ruptures the membrane and creates a passageway permitting fluid to flow freely through the tubular member and adjoining tubing.

Abstract: A closure member for pierceable access ports of flexible containers of the type adapted for effective safe storage and use of parenteral fluids and similar sterile solutions, the access port having a pierceable access closure diaphragm, wherein the closure member includes a base portion in sealed engagement over the neck of the access port on the container, with a rigidifying and strengthening portion or an insert in sealed engagement therebetween, and a free-standing portion extending from the base portion and having a sealed end, the free-standing portion being connected to the base portion by a fragible thinned material section adapted to be ruptured to permit the free-standing portion to be removed, thereby providing access to the pierceable diaphragm for insertion therethrough of a parenteral solution administration spike.
