METHOD AND APPARATUS FOR MAINTAINING A PRESSURE WITHIN A PRODUCT DISPENSER

摘要

A dispenser contains a productivity bag (202) and a system for generating a dispensing pressure in a chamber (204) created by the space between the product bag and the walls (203) of the dispenser. The act of filling the product bag with product establishes an initial dispensing pressure. A pressure regulator (208) in the chamber re-establishes the dispensing pressure after each spray down.
