Abstract
A reinforced container formed of foldable paper board and having triangular column supports at opposite diagonal corners. The container is double jointed, being formed of two container segments. Each container segment has one inner flap which extends into the container from the point that the container segment is joined with the mating segment. The flap forms a triangular supporting column with the adjacent corner of the container to provide for additional stacking strength.
