A multilevel stacking container having opposed end walls of complementary configuration such that one container may be stacked upon a like container at a first level in a like end to like end relationship and stacked at a second level in a like end to complementary end relationship. The end walls are so configured as to accommodate transverse sliding of the upper container laterally across the lower container into either of the aforementioned stacked relationships without snagging prior to final vertical alignment. Abutment means are operable to maintain the stacked containers against movement out of vertical alignment once in a stacked relationship. As employed in the following claims, the word “coextensive”is to be construed as meaning in alignment－laterally or transversely of the container－that is, elements on opposite end walls of the container are “coextensive”with each other when they are located at equal distances from one of the container side walls (even though the element on one end wall may be vertically offset from the other “coextensive”element).

In a multilevel stacking container adapted to be stacked upon a like container at any one of a plurality of different levels relative thereto, said container including a rectangular bottom, a pair of opposed side walls projecting upwardly from opposite sides of said bottom, and first and second end walls projecting upwardly from the opposed ends of said bottom; the improvement wherein each of said end walls comprises an inner web fixedly secured along its lower edge to the associated end of said bottom and lying in a first vertical general plane, said inner web having a horizontal upper edge interrupted by uniformly spaced recesses each defined by opposed vertical side edges extending downwardly a uniform distance from said upper edge to a horizontal edge defining the bottom of the recess whereby the top of said inner web is defined by alternate raised and lowered horizontal edge sections, an outer upper web lying in a second general plane parallel to and offset outwardly from said first vertical plane, said outer upper web having a continuous horizontal upper edge projecting upwardly above the raised edge sections of said inner web, a series of spaced lower outer web sections lying in a third general plane parallel to and located between said first and said second general planes and having horizontally aligned horizontal lower edges projecting downwardly below said bottom, means securing the aforementioned webs and web sections to each other with said outer web sections located in coextensive relationship along said end wall to said raised edge sections of said inner web, said means securing including means defining a horizontal platform extending between said inner and said upper outer webs coextensive with and slightly below the top of each of said raised edge sections, the raised edge sections of said first end wall being located directly opposite the lowered edge sections of said second end wall, means defining a relatively narrow vertical slot extending upwardly from the lower edges of at least two of said lower outer web sections of said first end wall, and locater posts on said inner web of said second end wall complementary in shape to said slots and projecting upwardly from at least two coextensive lowered edge sections of the last mentioned inner web, said posts having horizontal upper edges horizontally aligned with the upper surfaces of said platform.
