A container made from corrugated paperboard has more than four sides and is constructed to resist distortion when force is applied to the ends or sides of the container, and also to resist crushing when containers are stacked on top of one another. In one embodiment, the container has six sides, with two side walls, two end walls, and two diagonally opposed diagonal corner panels and two diagonally opposed square corners. In another embodiment, the container has seven sides, with two side walls, two end walls, and three diagonal corner panels and one square corner. In a further embodiment, the container has eight sides, with two side walls, two end walls, and four diagonally opposed diagonal corner panels. In this embodiment, the diagonal corner panels are oriented so that they subtend an angle of from about 35° to about 40°, and preferably 38°, with respect to the longitudinal axis of the container. The diagonal corner panels in the other embodiments may also be oriented at 38°, or from about 35° to about 40°.

What is claimed is: 1. A multi-sided container having opposite side walls, opposite end walls, a longitudinal axis and a plurality of diagonal corner panels, wherein at least one said side wall and an adjacent said end wall are disposed orthogonally with respect to one another and connected to define at least one square corner; and at least one said end wall having a width such that at least a portion of at least one of its opposite side edges projects beyond a portion of an adjacent said diagonal corner panel, does not project beyond a plane of an adjacent said sidewall, and terminates such that at least one outer edge of the portion of at least one side edge is not in alignment and does not intersect with the plane of the adjacent said sidewall wherein said diagonal corner panel being configured between said end wall and said side wall, wherein no portion of said opposite side edges of said end wall is connected to no portion of said adjacent said side wall, and wherein the container has at least six sides, including said side walls and end walls, and at least three said diagonal corner panels. 2. The container according to claim 1, wherein said end walls are shorter than said side walls. 3. The container according to claim 1, wherein at least one said diagonal panel is oriented at an angle of from about 35° to about 40° with respect to the longitudinal axis of the container. 4. The container according to claim 1, wherein at least one said diagonal panel is oriented at an angle of from about 38° to about 40° with respect to the longitudinal axis of the container. 5. The container according to claim 1, wherein at least one notch is formed in at least one said side edge of at least one said end wall. 6. The container according to claim 1, wherein at least one notch is formed in at least two said side edges of at least one said end wall. 7. The container according to claim 1, wherein at least a portion of at least one said end wall comprises a plurality of end panels that overlap one another. 8. The container according to claim 1, wherein at least a portion of at least one said end wall comprises a plurality of end panels that overlap one another, each end panel having an upper edge with interlocking means thereon so that the panels may be manually engaged with one another and interlocked for manual erection of the container. 9. The container according to claim 1, wherein at least two said side walls and an adjacent said end wall are disposed orthogonally with respect to one another to define at least two said square corners. 10. The container according to claim 9, wherein at least two said side walls and an adjacent said end wall are disposed orthogonally with respect to one another and are connected to define at least two said square corners. 11. The container according to claim 1, further comprising a bag disposed therein. 12. The container according to claim 1, comprising at least seven sides defined by two said opposite end wails, two said opposite side walls, and at least three said diagonal corner panels. 13. The container according to claim 1, comprising at least six sides defined by two said opposite end walls, two said opposite side walls, and at least two said diagonal corner panels. 14. The container according to claim 1, wherein said at least one outer edge of the portion of at least one side edge does not extend through said plane of said adjacent said sidewall. 15. The container according to claim 1, wherein at least a portion of said at least one said end wall comprises a plurality of end panels that overlap one another wherein at least one of said overlapping end panels having a width such that at least a portion of at least one of its opposite side edges projects beyond said portion of said adjacent said diagonal corner panel, does not project beyond a plane of an adjacent said sidewall, and terminates such that at least one outer edge of the portion of at least one side edge of said at least one of said overlapping end panels is not in alignment with said plane of said adjacent said sidewall and does not intersect with said plane of said adjacent said sidewall. 16. The container according to claim 15, wherein said at least one of said overlapping end panels is an outermost overlapping end panel. 17. The container according to claim 15, wherein said at least one outer edge of the portion of at least one side edge of said at least one of said overlapping end panels does not extend through said plane of said adjacent said sidewall.
