Abstract: A fixture for fluid dispensing bags having lower portions with nozzles. The bags are used with the lower portions folded forwardly and the nozzles pointed downwardly. The nozzles form keys which differ for different groups of the bags. The fixture has a forwardly extending shelf for the lower portions of the bags and in which a hole is formed and an insert is positioned in the hole and has a nozzle hole forming a key hole fitted by the nozzles of only one group of the bags.

Abstract: A dispensing device for a bag container a liquid, made of flexible material and forming upper and lower walls through which holes are formed for receiving the device, has a tubular lower part with a top flange which is sealed to the inside of the lower wall and depends through the hole in the lower wall. A tubular upper part has a top flange sealed to the inside of the upper wall and depends through the hole in that wall and is telescoped inside the lower part so as to move up and down in the lower part. The top of the upper part forms a piston such as a collapsible dome extending upwardly through the hole in the upper wall and exposed on the outside of the upper wall and therefore exposed on the outside of the bag. The lower part has a lower end having a self-closing valve and has at least one side port normally open to a space between the flanges and therefore between the bag walls.
