Abstract:
A stackable, self-aligning, corrugated cardboard container comprising:a rectangular bottom panel having a pair of opposite ends and a pair of opposite sides generally perpendicular to said opposite ends; two end panels extending upwardly from said opposite ends of said bottom panel; two side panels extending upwardly from said opposite sides of said bottom panel to a maximum height approximately the same as the height of said end panels, said end panels being adjacent to said side panels to form four corners; four corner panels of the same height as said end panels, each corner panel extending diagonally across a corresponding one of said corners and having one end attached to a corresponding one of said end panels, and another end attached to one of said side panels adjacent to said corresponding corner panel; and at least four shaped interlocking tabs, each tab having a relatively wide base and a relatively narrow head and being integrally formed as part of a corresponding one of said four corner panels and upwardly projecting beyond said end panels, wherein said bottom panel defines a plurality of generally circular apertures arranged to receive interlocking tabs of a similar container situated below said bottom panel and having all of the features of the container, the apertures being configured such that placement of the apertures of the container over the tab heads of the similar container urges the container to shift into alignment over the similar container as the wide base of the shaped interlocking tabs engage the apertures.
