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 first and second opposed pairs of flaps, wherein a T-shaped locking tab is formed on the free edge of one of the flaps of the first pair, and a notch is formed in the free edge of each of the flaps of the second pair. In erecting the box, the flaps of the first pair are first folded inwardly over the bottom of the box, with the free edges thereof confronting one another and the flaps lying in substantially flush, coplanar relationship. The flaps of the second pair are then folded inwardly over the first pair, with the free edges of the flaps of the second pair lying in confronting relationship with one another and the notches therein defining a central opening. The locking tab is pulled outwardly through the central opening to lock the flaps in their inwardly folded relationship and define a smooth interior bottom surface in the box.
