An octagonal bulk bin of corrugated paperboard has opposed parallel side walls spaced a predetermined distance apart and opposed parallel end walls spaced a predetermined distance apart. The side and end walls are joined by diagonal corner panels. The diagonal corner panels are made wider than the corner panels in a conventional bin, and the side and end walls are narrower, with the corner panels and the end walls having approximately the same width, while maintaining the predetermined spacing. This configuration reduces the bulge experienced when product is loaded into the bin. In addition to the wider corner panels, or in lieu thereof, scores may be placed in at least one of the side and end panels to define a line along which controlled and predetermined buckling will take place, if buckling occurs.

1. An octagonal bulk bin formed of corrugated paperboard and having opposed parallel side walls spaced a predetermined distance apart, opposed parallel end walls spaced a predetermined distance apart, and diagonal corner panels joining the side and end walls, wherein: said diagonal corner panels have the same width as said end walls, the side and end walls are the reduced width at said predetermined distances apart compared to a conventional bin in which the diagonal corner panels arc of less width, and said side walls have a width approximately fifty percent greater than the width of the end walls and the diagonal corner panels, resulting in an octagon that is equilateral except that it is elongated approximately twenty percent in a direction parallel to the side walls, whereby said bin fits a predetermined standard pallet size and said side and end walls undergo minimum bulge when a flowable product is loaded into the bin, and a scoreline is formed in at least one of said side and end walls to form a line along which said wall will buckle in a controlled and predetermined manner, if it buckles, from the pressure of material placed in the bin, said scoreline having a generally parabolic shape converging downwardly from opposite upper corners of said wall and terminating in a curved bight spaced above the midpoint of the wall. 2. A bulk bin as claimed in claim 1, wherein: a further scoreline forms a second generally parabolic shape converging upwardly from opposite lower conrners of said wall and terminating in a curved bight spaced below the midpoint of the wall. 3. A bulk bin as claimed in claim 1, wherein: at least one reinforcing strap extends around said bin to reinforce it against radial expansion. 4. A bulk bin having side walls, wherein: a weakened area is formed in at least one of said side walls to form a line along which said at least one side wall will buckle in a controlled and predetermined manner, if it buckles, from the pressure of material placed in the bin, said weakened area having a generally parabolic shape converging downwardly from opposite upper corners of said at least one side wall and terminating in a curved bight portion. 5. A bulk bin as claimed in claim 4, wherein: said weakened area comprises a scoreline, and said bight portion is spaced above a midpoint of said at least one side wall; and a further scoreline forms a second generally parabolic shape converging upwardly from opposite lower corners of said at least one side wall and terminating in a curved bight portion spaced below the midpoint of said at least one side wall. 6. A bulk bin as claimed in claim 4, wherein: said side wall include a pair of opposed parallel side walls, opposed parallel end walls and diagonal corner panels joining adjacent side and end walls, said opposed side walls and opposed end walls being spaced predetermined distances apart. 7. A bulk bin as claimed in claim 6, wherein: the diagonal corner panels have the same width as the end walls, and said end walls and diagonal corner panels have a width that is approximately two thirds the width of the side walls, defining an octagonal bin having length and width dimensions to fit on a predetermined pallet size, and said side and end walls undergo minimum bulge when a flowable product is loaded into the bin. 8. A bulk bin as claimed in claim 7, wherein: the bin is formed of corrugated paperboard. 9. A bulk bin as claimed in claim 4, wherein: the weakened area comprises a scoreline.
