Abstract: A collapsible container that comprises first and second sidewalls and first and second end walls pivotally connected to a base. The first sidewall includes at least one latching member that cooperates with a latching member of the first end wall to secure the first sidewall and the first end wall together when the first sidewall and the first end wall are in upright positions. The container also includes a wall locking system that has a plurality of locking members on the first sidewall and at least one locking member on the first end wall. The locking member on the first end wall cooperates with the locking members on the first sidewall to prevent the first sidewall from moving relative to the first end wall in at least one direction when the first sidewall and first end wall are in upright positions. The container further includes a wall alignment system that has a first member extending from one of the sidewalls, and a second member that extends from one of the end walls.
