CONTAINER WITH REINFORCING AND SUPPORTING TRIANGULAR PRISMS FORMED AT ITS CORNERS BY SIDE END EXTENSIONS WITH THREE SECTIONS FOLDED SO THAT LAST SECTION LIES AGAINST THE SIDE

摘要

A stackable container has corners which have ridges that extend above the sidewall. These ridges mate with slots in the bottom walls of similar containers when the containers are stacked. Corner flaps which connect adjacent sidewalls form triangular posts that serve to support the weight of containers stacked on it. The section of the corner flap that extends along the adjacent sidewalls also have ridges that extend above the sidewall but the section that extends diagonally across the corner has a height that is equal to the height of the sidewalls. This allows this section to rest against the bottom wall of a container stacked on it instead of mating with a slot.
