ABSTRACT:
A container for fluent material has a limp flexible bottom and an upstanding limp flexible perimetral circular wall. The wall is kept upstanding by flexible support means between the upper edge of the wall and the upper horizontal member of a framework surrounding and spaced from the perimetral wall. The wall is of waterproof-coated woven synthetic fabric with the warp running lengthwise around the wall and the weft upright. The fabric has a strength-to-weight ratio and stretch characteristic sufficient that the wall requires no internal reinforcement or external support against outward pressure from contents when filled into the container.
