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, with each panel including a foldably connected bottom flap and with the bottom flaps being in overlapped and interengaged relationship to form the bottom wall of the bulk bin. More particularly, each corner panel includes a foldably connected, horizontally disposed rectangular flap which is initially folded inwardly such that each flap is in overlapping relationship. Each flap of one pair of flaps extending from opposed side panels is slotted to include two parallel slots disposed perpendicular to the fold line thereof, and extending for a distance corresponding to one-half of the width of the flap extending from the adjacent side panel. By this construction, the flaps extending from the side panels may be interengaged for forming a rigid bottom wall for the bulk bin.

Claim 1
Independent Claim
214 words
An octagonal-shaped paperboard bulk bin comprising: a side wall formed from first and second opposed pairs of substantially rectangular, upstanding side panels and first and second opposed pairs of substantially rectangular, upstanding corner panels that are alternatively, foldably connected, said side panels being of greater width than said corner panels, and with each corner panel including a horizontally disposed, substantially rectangular flap foldably connected to the bottom edge thereof, each side panel of said first pair of opposed side panels including a horizontally disposed, substantially rectangular flap foldably connected to the bottom edge thereof, each side panel of said second opposed pair of side panels having a horizontally disposed, substantially rectangular slotted flap, each slotted flap including two parallel slots disposed perpendicular to the fold line thereof and extending from the edge thereof opposite said fold line for a distance corresponding to approximately one-half the width of each flap of said first pair of opposed side panels whereby with the flaps extending from said corner panels overlapping one another and being wholly disposed within the bulk bin, and with the flaps extending from said first pair of opposed side panels extending through the slots formed in said slotted flaps for engagement with said slotted flaps, a bottom wall for the bulk bin is formed.
Claim 2
Dependent Claim
214 words
An octagonal-shaped paperboard bulk bin comprising: a side wall formed from first and second opposed pairs of substantially rectangular, upstanding side panels and first and second opposed pairs of substantially rectangular, upstanding corner panels that are alternatively, foldably connected, said side panels being of greater width than said corner panels, and with each corner panel including a horizontally disposed, substantially rectangular flap foldably connected to the bottom edge thereof, each side panel of said first pair of opposed side panels including a horizontally disposed, substantially rectangular flap foldably connected to the bottom edge thereof, each side panel of said second opposed pair of side panels having a horizontally disposed, substantially rectangular slotted flap, each slotted flap including two parallel slots disposed perpendicular to the fold line thereof and extending from the edge thereof opposite said fold line for a distance corresponding to approximately one-half the width of each flap of said first pair of opposed side panels whereby with the flaps extending from said corner panels overlapping one another and being wholly disposed within the bulk bin, and with the flaps extending from said first pair of opposed side panels extending through the slots formed in said slotted flaps for engagement with said slotted flaps, a bottom wall for the bulk bin is formed.
Claim 3
Dependent Claim

An octagonal-shaped paperboard bulk bin as in claim 1 wherein said bin is formed from a single wall corrugated board.
Claim 4
Dependent Claim
213 words
A paperboard blank for a bulk bin comprising: a side wall formed from first and second opposed pairs of substantially rectangular side panels and first and second opposed pairs of substantially rectangular corner panels that are alternatively, foldably connected, said side panels being of greater width than said corner panels, and with each corner panel including a substantially rectangular flap foldably connected to the bottom edge thereof, each side panel of said first pair of opposed side panels including a substantially rectangular flap foldably connected to the bottom edge thereof, each side panel of said second opposed pair of side panels having a substantially rectangular slotted flap, each slotted flap including two parallel slots disposed perpendicular to the fold line thereof and extending from the edge thereof opposite said fold line for a distance corresponding to approximately one-half the width of each flap of said first pair of opposed side panels whereby the flaps extending from said corner panels overlap one another and are wholly disposed within an erected bulk bin, and wherein the flaps extending from said first pair of opposed side panels extend through the slots formed in said slotted flaps for engagement with said slotted flaps in an erected bulk bin to provide a bottom wall for the bulk bin.
Claim 5
