ABSTRACT:
A blank, defining an I beam partition, has a center panel extending at each end edge into a foldably connected substantially L-shaped end panel. The ell extensions of the L-shaped end panels are adjacent one of the side edges of the center panel. At least one of the L-shaped end panels has about the center of its widest portion a cut portion defining an aperture. The L-shaped end panels are bent about their edge foldably connected to the center panel, to extend substantially perpendicularly away from the center panel thus defining an I beam partition to be snugly inserted in boxes. The invention is also directed to a box having the I beam partition wherein each of the L-shaped end panels is snugly positioned adjacent one of the ends of the box to reinforce the ends. The center panel extends between the L-shaped end panels, dividing the box in two portions and cooperating with the L-shaped end panels and the ends to prevent inward and outward movements of the ends of the box. The aperture cooperates with the box's handhole to enable strengthening of the hand grasping of the box.
