ABSTRACT:
The box is easily assembled by hand, is suitable for construction out of plastic materials, and can be produced at relatively low cost. The box includes an elongated wrap panel with a plurality of flat surfaces formed by folding at lateral creases. The flat surfaces include a bottom surface and two flat surfaces forming a top wherein the two flat surfaces are adjacent to the lateral edges of the wrap panel. Each of the two sides of the box are formed from a plurality of flat surfaces. The box also includes two end panels, each with a plurality of tabs which engage with the box sides and each end panel having a horizontal slit extending there through. The bottom surface of the box includes a locking tab at each end. The locking tab includes a pair of hinged portions permitting the locking tab to fold inward wherein a portion of the bottom surface between the pair of hinged portions forms a flat support tab that is formed by a slit in the locking tab. The locking tab also includes a first generally U-shaped portion and a second generally U-shaped portion extending outward from the first U-shaped portion and hingingly attached to the first U-shaped portion. When assembled, the first U-shaped portion extends into the interior of the box adjacent to the end panel and the second U-shaped portion extends outside the box through one of the horizontal slits in the end panel.
