Abstract
A pair of superimposed panels are heat sealed together to define a reservoir in a dispenser pouch, adapted to contain a liquid therein. A spout is formed in offset relationship on a lower end of the pouch and defines a charging chamber that communicates with the reservoir to retain a pre-measured charge of the liquid therein. The spout terminates at a normally closed valve that opens when a predetermined external and downward pumping pressure is applied to the spout. A retention band may be secured transversely across on outer side of one of the panels to retain the spout when it is reverse-bent and slipped thereunder. The pouch is adapted for mounting in a dispensing unit having a dual-action pressure plate for pumping and dispensing the pre-measured charge of liquid from the spout.
