A foldable container assembly (10) comprises a base (12) having a plurality of sides, at least one side wall (14, 16, 18, 20) extending vertically upwardly from each side of the base (12) with the tops (22) of the side walls all being aligned in a horizontal plane. The invention is characterized by hinges (24) interconnecting each of the side walls to the base with the hinge for a first wall (14) being in a vertically spaced horizontal plane from the hinge for a second side wall (16) for folding the first (14) and second (16) side walls over the base (12) and into overlapping vertical relationship to one another. Hinges (24) on the first and second walls (14, 16) have an associated link (50) having slots (52) therein for allowing the side wall to move vertically relative to the base (12) for locking and unlocking the walls from one another. Two opposing side walls (14, 16) have lugs (32) along opposite edges thereof and an independent channel member (42), affixed to the opposite edges of each of two other opposing side walls (18, 20), has lug-receiving openings (38) and lug-retaining pockets (40) therein for movement of the lugs (32) into the lug-receiving openings (38) and vertically downward into the lug-retaining pockets (40) to interlock the side wall (14, 16) with an adjacent side wall (18, 20). Fork-lift channels (70) allow either full or empty containers (10) to be mechanically lifted for stacking while legs (60), projections (62) and alignment pegs (70) coact with complementary steps (68) and recesses (92) to relatively position and stack the containers (10).
