Abstract: 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.

Abstract: A shipping container, e.g., tray, formed-up from a unitary blank of sheet material improves upon known triangular cornerpost-type containers by providing reinforcing layers formed from a fold-over flap attached to an upper edge of a wall panel having post-forming corner panels at its lateral ends. The fold-over flap is laid-up against, and is secured to, a diagonal panel of the triangular post structures formed at each container corner, as well as adjacent portions of the corner-forming walls. Tabs formed by a hinged connection of the wall panel and fold-over panel are aligned with notches formed in lower edges of the walls, allowing for interengagement of multiple trays in a stacked configuration. The construction results in superior stacking strength and improved stacking stability, thereby facilitating material handling, shipping and display.

Abstract: A stackable container has corners which have ridges that extend above the sidewall. These ridges mate with slots in the bottom walls of similar containers when the containers are stacked. Corner flaps which connect adjacent sidewalls form triangular posts that serve to support the weight of containers stacked on it. The section of the corner flap that extends along the adjacent sidewalls also have ridges that extend above the sidewall but the section that extends diagonally across the corner has a height that is equal to the height of the sidewalls. This allows this section to rest against the bottom wall of a container stacked on it instead of mating with a slot.
