Abstract
A three-piece container comprises top and bottom walls, apposite end walls, opposite side walls, and reinforced corners. First and second end pieces are configured to form first and second container end walls. The end pieces are each folded to define an inner end wall panel and an overlying outer end wall panel. First partial side wall panels extend perpendicularly from opposite sides of the outer wall panel. Second partial side wall panels are joined to the inner end wall panel by a diagonal web that forms a reinforcing corner post in each corner of the container. A wrapper is configured to be joined to the first and second end pieces and is folded to define the top wall, the bottom wall, and the opposite side walls. The wrapper overlies the partial side wall panels to define a triple wall side wall construction.
