Self-locking design for octagonal container

An octagonal container having a unique bottom closure and a blank therefor are provided. The body of the octagonal container includes a pair of major wall panels, a pair of minor wall panels, and four corner wall panels. Each major and minor wall panel is foldably connected to a corner wall panel on either side. In the preferred embodiment, one of the minor wall panels is formed from two pieces, which are secured in overlapping relation to one another. The closure section includes a pair of rectangular major cover flaps, a pair of rectangular minor cover flaps, and four polygonal corner flaps. Each major cover flap is foldably connected to a major wall panel. Each corner flap is foldably connected to a corner wall panel. Each minor cover flap is foldably connected to a minor wall panel. In the preferred embodiment, one of the minor cover flaps is formed from two pieces, which are fastened in overlapping relation to one another. Each minor cover flap features a pair of locking tabs which are coextensive with the minor cover flap and are defined by one or more slit lines. A central horizontal score line runs between the locking tabs. Each major cover flap features a pair of vertical slots aligned in parallel. The closure is formed by folding the corner flaps inward at right angles to the corner wall panels and then folding the major cover flaps inward at right angles to the major wall panels to overlie the corner flaps. The minor cover flaps are folded inward at right angles to the minor wall panels to overlie the major cover flaps. Finally, each minor cover flap is folded along its central horizontal score line to release the pair of locking tabs, and each locking tab is inserted into the corresponding slot in a major cover flap to form a secure, flat-bottomed closure.
