ABSTRACT:
A container (21) for storing and shipping produce is reinforced with at least one cross beam (20) extending across the bottom wall (26) of the container to form a bridge under loose product placed in the container to support at least a portion of the weight of the product and prevent sagging of the container bottom. The cross beam is positioned and held in place by engaging the ends of the cross beam in recesses (71) formed by crushed areas (82) on an inner surface of opposing side walls, or cut-outs (93) in the side walls, and/or by flaps (42, 43) folded upwardly from the container bottom wall and to which the cross beam is attached.
