Abstract
A collapsible liquid containment device having a floor, side walls and peripheral skirt made of a flexible, foldable, liquid-impermeable material, where the side walls are supported by foldable brace members having an angled buttress member and an insertion member joined by a hinge, the buttress members being attached to the skirt. The insertion members are inserted into vertical pockets mounted on the exterior of the side walls, and the upper rim of the side walls is provided with a retention flap having a lower opening which receives the hinged joint between the buttress member and the insertion member. Preferably a rim support tab is affixed to the hinged joint to support the uppermost portion of the side wall. The brace members can be folded into a flat configuration when the insertion member is removed from the vertical pockets, allowing the entire device to be collapsed and folded.
