ABSTRACT:
A flexible and collapsible storage tank (10) for holding large volumes of material is fabricated in a rectangular shape from long lengths of a rubberized square-woven fabric. The lengths of fabric are oriented with overlapping adjacent edges to form inner (122) and outer (124) envelope structures which are integrally vulcanized into a homogeneous tank body (20). The inner envelope (122) is formed by longitudinally oriented fabric plies (22) having overlapping adjacent edges (22a) while the outer envelope (124) is formed by edge plies of fabric (26) folded about the peripheral edges of the inner envelope (122) and orthogonally oriented fabric plies (24) positioned on either side of the inner envelope (122). The tank (10) includes an air vent valve (40) mounted in its top and a closure (30) which clamps and seals a corner exposure (20a) of the tank body (20) and provides access and communication into the tank for filling and emptying.
