    • A collapsible box has hinges which are vertically staggered to permit the box to collapse into a relatively flat configuration for easy stacking and transport. When the box is erected, interlocking features on the edges of the sides of thus box interengage to hold the box in a vertical configuration. A peripheral groove is provided to receive a shipping strap. The walls of the box are hinged to the bottom of the box in such a way that the walls may pivot inwardly to collapse the box as well as outwardly to permit easy cleaning of the inner surfaces of the box walls.
