ABSTRACT:
Boxes for produce and the like formed by corrugated paperboard containers having end walls defining vertical slots that are aligned when the containers are stacked. Column-forming members are inserted in the slots and interlocked vertically. The containers are supported primarily by the inserts so that the combined weight of containers above is not borne solely by the end walls.
