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°.

1. In a multi-sided container having opposite side walls, opposite end walls, a longitudinal axis, and at least two diagonal corner panels oriented at an angle of 38° with respect to the longitudinal axis of the container, the improvement comprising: at least one said side wall and an adjacent said end wall disposed orthogonally with respect to one another and connected to define a square corner, said square corner serving to resist distortion of the container when a force is applied laterally against the sides or ends of the container, and the diagonal corner panels providing stacking strength for containers stacked on top of one another. 2. A container as claimed in claim 1, wherein: the container has six sides, including said side walls and end walls, and said two diagonal corner panels, and there are two diagonally opposite square corners. 3. A container as claimed in claim 2, wherein: the container end walls each comprise a plurality of overlapping end panels having upper edges with interlocking means thereon so that the panels may be manually engaged with one another and interlocked for manual erection of the container. 4. A container as claimed in claim 1, wherein: the container has seven sides, including said side and end walls, and three diagonal corner panels, and there is one square corner. 5. A container having opposite side walls, opposite end walls, a longitudinal axis, and a plurality of diagonal corner panels, the improvement comprising: said diagonal corner panels being oriented so that they subtend an angle of from about 35° to about 40° with respect to the longitudinal axis of the container, thereby providing a resultant force vector that is axially oriented to resist distortion of the container when a force is exerted against the ends of the container, and also providing stacking strength when the containers are stacked on top of one another. 6. A container as claimed in claim 5, wherein: the diagonal corner panels subtend an angle of 38° with respect to the longitudinal axis of the container. 7. A container as claimed in claim 6, wherein: the container has eight sides, including said side and end walls, and four diagonally opposed diagonal corner panels. 8. A container as claimed in claim 6, wherein: the container has six sides, including said side and end walls, and two diagonally opposed diagonal corner panels, and there are two diagonally opposed square corners. 9. A container as claimed in claim 6, wherein: the container has seven sides, including said side and end walls, and three diagonally opposed diagonal corner panels, and there is one square corner.
