Abstract
An apparatus for pressure dispensing of fluid products is provided having an elastomeric pressure unit disposed in surrounding relationship to a flexible, fluid-tight liner. The liner has its open end sealably engaged with a valve support, having a dispensing valve therein. The inherent contracting force which returns an expanded elastomeric pressure unit to its normal unexpanded position, provides the dispensing pressure for the product contained within the flexible liner, while the liner prevents contact between the product and the elastomeric material of the pressure unit. This abstract is not to be construed in any way to define or limit the invention set forth below.
