ABSTRACT:
An apparatus for containing and dispensing a liquid under pressure includes a flexible container, preferably blow molded of a plastic composition, defining an inner region for containing the fluid under pressure. The container is inert with respect to the liquid contained therein and has a plurality of longitudinally extending creases to allow folding of the flexible container inwardly along the creases. The flexible container is capable of being folded along the creases in its empty condition radially and expanded when filled with the fluid under pressure. A tubular fabric sleeve open at both ends which is elastic in radial directions surrounds the flexible container in its folded condition. A tubular resilient member also open at both ends is positioned about the fabric sleeve when the flexible container is in its folded condition. The resilient member is controlled by frictional interaction with the fabric sleeve so as to be capable of expanding in substantially radial directions when the flexible container is filled with the fluid under pressure. A method of producing the inventive apparatus is also disclosed.
