Patent abstract
Collapsible structures are provided that have an enclosed interior space that can be used to hold and contain water or other matter. The interior space is defined by an enclosing wall and a base that are both waterproof to prevent leakage of the water or matter contained in the interior space. None, one or more foldable frame members can be provided as part of the enclosing wall and the base. The frame members allow the resulting structure to be twisted and folded to reduce the overall size of the structure.
