Abstract:
A collapsible material handling container (10) including a base (12) having a plurality of sides (30, 32), a pair of opposed sidewalls (14) and a pair of opposed end walls (16) and hinges defining axes (68, 70) associated with each wall (14, 16) and interconnecting each wall (14, 16) to the base (12). The walls (14, 16) are rotatably moveable about their respective hinge axes (68, 70) between a collapsed position wherein the walls (14, 16) are folded one on top of the other and an upright position wherein the walls (14, 16) extend vertically upward from the base (12) to define an interior (18) of the container (10). The hinge axes (68) for the opposed sidewalls (14) are disposed on a common plane bisecting these axes (68). Similarly, the hinge axes (70) for the opposed end walls (16) are disposed on a common plane bisecting these axes (70). The base sides (30) for the opposed sidewalls (14) form a pair of ramping surfaces (72) defining oppositely opening acute angles with the hinge axes (68) for the sidewalls (14) for supporting at least one of the opposed end walls (16) along the ramping surfaces (72) when the end wall (16) is in its collapsed position.
