Abstract
A collapsible liquid reservoir has a flexible side wall having a lower step, a middle step and an upper step. Each of the steps includes a riser segment and a tread segment. The riser and tread segments are pivotably connected to one another at an external hinge. When the step is collapsed its segments define an acute step angle between them of about 23°. When the step is expanded its segments define an obtuse step angle between them of about 115°. The tread of at least one step is pivotably connected to the riser of an adjacent step at an internal hinge. The step segments joined to the internal hinge are symmetrical about a bisector of that hinge. The reservoir has a truncated pyramid shape defined by a generally square base and four trapezoidal side panels joined to one another at corners.
