Abstract
Abstract A washbasin formed from a flexible sheet of material and rigidified by parallel spaced reinforcing elements, is held erect by corner flap hooks received in loops on the outside of adjacent side panels against which the corner flaps are folded. Spaced side panels are folded onto the bottom panel and then folded therewith into a compact form for storage purposes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
201 words
A foldable liquid retaining basin comprising a sheet of liquid impervious flexible material having a bottom panel portion bordered by peripheral side panel portion interconnected by foldable flap portions, said side panel portions being connected along folds to the bottom panel portion and foldable to erect positions relative to the bottom panel portions, a plurality of parallel spaced rigidifying slat elements secured to each of the bottom and side panel portions forming a plurality of foldlines therebetween, two of the side panel portions spaced from each other and extending transversely of the rigidifying elements when folded onto the bottom panel portion being foldable with the bottom panel portion along said foldlines into a compact form, the slat elements secured to said two of the side panel portions and the bottom panel portion, respectively, being separated from each other along the folds between said two of the side panel portions and the bottom panel portion, and fastener means for holding the side panel portions in said erect positions with the rigidifying elements on said two of the side panel portions being in substantially perpendicular relation to the rigidifying elements on the bottom panel portion and the other of the side panel portions.
