A single-piece containerboard blank (10) is provided having hingedly-connected first and second side walls (26), (34) in which the second side wall (26) is smaller in length than the first side wall (34). The second side walls each include an outer abutment edge (42). The first side walls include first and second interior end walls (50), (52). Each second interior end wall (52) includes a hypotenuse panel (62) with an inwardly-oriented edge (66). As assembled, the blank (10) forms a container having opposed multi-ply side panels, opposed end panels, and a bottom panel. The hypotenuse panels (62) are oriented in an upright manner and ultimately positioned so that their inwardly-oriented edges (66) push against the first side wall and preferably also against the abutment edges (42) of the second side wall (34). The hypotenuse panels (62) offer stacking strength and reinforcement to the container. In one embodiment, tabs (92) and mating openings (96) are provided to help stabilize the container when multiple containers are placed in a stack. In another embodiment, top closure panels (100) are provided to close off the upper portions of the container.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.]1. A single-piece containerboard blank erectable into a container having two multi-ply side panels, two end panels, and a bottom panel, the box blank comprising:(a) a generally rectangular bottom panel having longitudinal and transverse edges;(b) end walls, one of the end walls extending outwardly from each transverse edge of the bottom panel and connected thereto along a first transverse hinge line;(c) first side walls, one of the first side walls extending outwardly from each longitudinal edge of the bottom panel and connected thereto along a first longitudinal hinge line; the first side walls forming the outer wall in each of the side panels;(d) second side walls, one of the second side walls extending outwardly from each first side wall and connected thereto along a second longitudinal hinge line; each of the second side walls being of a longitudinal length that is less than the longitudinal length of its corresponding first side wall; each of the second side walls having forward and aft abutment edges;(e) first interior end walls extending longitudinally outward from the transverse edges of the first side walls and connected thereto along second transverse hinge lines; the first and second transverse hinge lines being generally collinear; and(f) second interior end walls extending transversely outward from each first interior end wall and connected thereto along a third longitudinal hinge line, the second interior end walls having a hypotenuse panel foldably connected to an inner edge of the second interior end wall along a third transverse hinge line: the hypotenuse panel extending longitudinally toward the second side wall abutment edges; the hypotenuse panel having an inwardly oriented edge; the third transverse hinge line being located outward of the second transverse hinge line and parallel thereto; the inwardly oriented edge of the hypotenuse panel being located inward of the second transverse hinge line; the hypotenuse panel being unconnected to its respective first interior end wall;wherein as assembled, the second side wall folds down upon the first side wall at the second longitudinal hinge line and the combination folds generally perpendicular to the bottom panel along the first longitudinal hinge line so that the abutment edges are oriented in an upright manner, and the hypotenuse panels are also oriented in an upright manner and positioned so that their inwardly oriented edges push against the first side wall.
