Abstract
A corrugated paperboard bulk box has opposed pairs of parallel side walls, and in a preferred embodiment, has interposed diagonal corner panels to form an octagonal box. The bottom of the box is closed by opposed pairs of interlocking major and minor bottom flaps, wherein one pair of flaps have notches in their free edges and the other pair of flaps have T-shaped locking tabs in their free edges. The notches form a central opening in the bottom when the flaps are folded closed, and the locking tabs are pushed through the opening to lock the flaps closed. Aligning tabs project outwardly from opposite side edges of one pair of opposed bottom flaps, and complemental slots are formed at the folding connection of another pair of bottom flaps, so that when the flaps are folded inwardly toward one another, the tabs extend into the slots to square the box and hold it square.
