A container is formed of a rigid, flat base, a rigid cover, and four vertically arranged, flat wall forming panels that are connected together along their adjacent vertical edges by hinge-like corner connectors and whose upper and lower edges are removably held in corresponding grooves formed in the base and cover. The panels are made of plastic extruded into parallel, spaced apart rigid sheets that are interconnected by numerous, spaced apart, transverse strips whose opposite ends are integral with the sheets. Each corner has a flat, sheet-like base strip that is integrally formed with a flexible center and rigid opposite edge sections that extend along the length of the connector base. Each of the opposite edge sections has an integral T-shaped rib extending along its length. The ribs are inserted endwise into elongated vertical slots formed in the endmost strips of the adjacent panel edges for fastening the connectors to the panels. Additional hinge joints may be formed on the vertical center lines of two opposed panels so that these panels may be folded together for folding the wall panels flat for positioning within the base and encapsulated by the cover for non-use, storage and shipping.

A collapsable, reusable container comprising: a flat, rigid base and four, normally vertically arranged, wall forming panels which are connected together along their adjacent vertical edges by hinge-like corner connectors, and whose lower edges rest upon the base; said corner connectors being formed of an initially flat, sheet-like base made of a single plastic extrusion which is longitudinally divided into an integral flexible center section stripe and opposite side edge, rigid, section stripes said connectors including roughly parallel flanges integrally formed on the connector base and extending outwardly from the same side of the connector base at each longitudinal edge of each of the rigid edge sections so that each rigid edge section forms the base, and its flanges form the legs, of a U-shaped channel, and the channels snugly receive the portions defining the vertical edges of the panels; each of said corner connectors being bendable from a first position wherein said flanges and attached panels are substantially parallel to one another and said sheet-like base is substantially flat to a second position wherein said flanges and attached panels are perpendicular to one another and said center section stripe is bent at approximately a right angle whereby the panels may be folded about the connector flexible center sections into a generally flat relationship for storage and handling.
