<p>An apparatus (10) for containing and dispensing a liquid under pressure includes a flexible container (36), preferably blow molded of a plastic composition, defining an inner region (40) for containing the fluid under pressure. The container (36) is inert with respect to the liquid contained therein and has a plurality of longitudinally extending creases (44) to allow folding of the flexible container (36) inwardly along the creases (44). The flexible container (36) is capable of being folded along the creases (44) in its empty condition radially and expanded when filled with the liquid under pressure. A tubular fabric sleeve (34) open at both ends and which is elastic in radial directions surrounds the flexible container (36) in its folded condition. A tubular resilient member (33) also open at both ends is positioned about the fabric sleeve (34) when the flexible container (36) is in its folded condition. The resilient member (33) is controlled by frictional interaction with the fabric sleeve (34) so as to be capable of expanding in substantially radial directions when the flexible container (36) is filled with the fluid under pressure. A method of producing the inventive apparatus (10) is also disclosed. </p> |
