Abstract
A flexible bag having expansible and collapsible cells can be used in a liquid dispenser. A rigid manifold, and in one instance a rigid frame is provided in the bag to keep passages open in use and to isolate one of the cells from the remaining cells. The manifold is capable of altering the volume of one of the cells so that the same bag can be used in different applications.
