Claim 1

In a multi-level stacking container having a rectangular bottom, first and second end walls projecting upwardly from respective opposite ends of said bottom and side walls projecting upwardly from each of the opposite sides of said bottom, said end walls having complementary vertically upwardly and downwardly extending recesses whereby two like containers may be alternatively stacked in a high-level stacked relationship by resting the first and second end walls of the upper container upon the respective second and first end walls of the lower container or in a low-level stacked relationship wherein the first and second end walls and side walls of the upper container are nested within the respective first and second end walls and side walls of the lower container; the improvement wherein said end walls are of a first length and a first height, said side walls being of a second length greater than said first length and having a main central section of a length at least equal to said first length and a height approximately one-half of said first height, relatively short end sections on each side wall of a height equal to said first height joined to the adjacent end walls, stacking rails projecting downwardly from said bottom along the respective side edges thereof, and means defining a pair of upwardly opening notches in each of said stacking rails spaced from each other by a distance equal to the spacing between said side walls whereby two like containers may be stacked one upon the other in a crosswise relationship wherein the end walls of one of the containers are parallel to the side walls of the other and with the upper edges of the central sections of the side walls of the lower container projecting upwardly into the notches in the stacking rails of the upper container to stably support the upper container in an intermediate level stacked relationship upon the lower container.
