ABSTRACT:
An elastic, fluid-impervious storage tank includes an outer tank member which is comprised of a pair of end tank sections and an intermediate tank section, the latter being provided with an inlet or filler pipe. Each end section is formed from a single blank of fiber-reinforced elastomer which is cut and folded so that the corner portions thereof are of rounded configuration. A flexible envelope formed of a film of chemical inert fluid-impervious plastic material is positioned interiorly of the outer tank member. The film envelope is slightly larger than the outer tank member and is folded with accordian pleats when it is inserted into the outer tank member so that it first unfolds transversely and then longitudinally as it is filled with a liquid.
