Abstract
Abstract A collapsible container formed from paperboard or similar foldable sheet material which is fabricated in collapsed condition and which is characterized by front and back wall forming panels hingedly joined at the bottom and having vertical side wall panels which are connected to portions of the corresponding side edges of the front and back wall panels on hinge lines each having angularly related portions which converge inwardly in the plane of the front and back wall panels and which side wall panels are collapsible on a central vertical hinge line into the plane of the collapsible front and back wall panels, the collapsed container being adapted to be opened up for use by inward pressure on the center hinge portions of the side wall panels sufficient to move the side wall panels toward each other to a fully open and locked position, the side wall panels being freed at bottom edge portions from the front and back wall panels, thereby enabling the bottom portions of the side wall panels to form leg-like supports and rendering the container self supporting when opened up and placed in an upright position.
