Abstract
Disclosed is a collapsible, portable container having a roof, a base, two foldable end walls and two removable side walls. The end walls and side walls of the container are load bearing elements having a twinned wall structure made of rotomolded plastic. The container is collapsed by removing the side walls and inwardly folding the end walls to draw the roof closer to the base. The load bearing capacity of the end walls and the side walls can be increased by arched indentations formed within the twinned wall structure.
