Abstract

Abstract An octagonal-shaped paperboard bulk bin particularly suited for use with heavy, palletized loads of meat products and the like is formed of alternating, upstanding side panels and corner panels. Each corner panel includes a foldably connected, horizontally disposed rectangular flap which is initially folded inwardly such that each flap is in overlapping relationship to the interior of the bin. An octagonal sheet having slots at opposite corners receives a portion of each corner panel therethrough to provide a bottom for the bin and to rigidify the bin construction during assembly and use.
