A three-level stack and nest container is provided with a row of outwardly projecting stacking feet along the lower edges of a pair of opposed end walls. Three stacking foot receiving seats are formed at the inner side of each end wall at different elevations in vertical alignment with each stacking foot so that two containers may be stacked or nested with the upper container at a high, intermediate or low elevation relative to the lower container depending upon which set of seats of the lower container are engaged by the feet of the upper container. Each vertically aligned group of seats includes recesses in the inner side of the end wall extending downwardly at opposite sides of the uppermost of the three seats. One recess will guide a stacking foot to the intermediate seat, the other recess will guide a stacking foot to the lower of the three seats.

1. In an open-topped, stackable container having a rectangular bottom and a pair of opposed end walls projecting upwardly at a slight outward inclination from opposite ends of said bottom whereby one of said containers may receive a like container in a nested or stacked relationship therein; the improvement comprising a plurality of outwardly projecting, horizontally spaced and aligned support feet fixedly mounted on the outer side of each end wall adjacent the lower edge of said end wall, means defining a plurality of support foot receiving recesses in the inner side of each of said end walls respectively above each of said support feet, each of said recesses extending downwardly from the top of the end wall, means defining vertically spaced and vertically aligned upper, intermediate and lower support seats in each of said recesses, each of said support seats being adapted to receive and support a support foot of a like container to support the like container respectively at an upper, an intermediate or a lower level upon the end wall, said upper seat being located adjacent the top of said end wall and centrally of the width of the recess, first guide means on said end wall at one side of said upper seat for guiding a support foot of a like container downwardly in said recess to said intermediate seat, and second guide means on said end wall at the opposite side of said upper seat for guiding a support foot of a like container downwardly in said recess to said lower seat. 2. The invention defined in claim 1 wherein each end wall comprises a main inner web extending upwardly from said bottom to the top of said end wall, said main web having openings therethrough extending downwardly from the top edge of said main web partially defining said recesses, an upper outer web extending downwardly from the top edge of said end wall in outwardly spaced, generally parallel relationship to said main web, said upper seats being fixedly mounted on said outer web and projecting inwardly therefrom, said intermediate seats being mounted upon and extending between said main and outer webs, and said lower seats being defined by the lower edges of said openings in said main web. 3. The invention defined in claim 2 wherein said main web lies in an upwardly and outwardly inclined general plane and said upper seats project inwardly from said outer web to inner sides lying in said general plane. 4. The invention defined in claim 3 wherein each of said support feet comprises a support web having a downwardly facing horizontal surface projecting outwardly from said end wall from an inner edge offset inwardly from vertical alignment with the inner surface of said main web at the lower edge of the associated opening in said main web, said horizontal surface having an outer edge offset outwardly from vertical alignment with the inner side of the associated upper seat. 5. The invention defined in claim 4 wherein each of said support feet further comprises a flange projecting downwardly from said support web below said horizontal surface at said outer edge thereof, and each of said upper support seats comprises an upwardly projecting retaining lip extending along its inner side adapted to be disposed inwardly of a flange on a support foot of a like container when the last-mentioned support foot is seated upon the upper support seat. 6. The invention defined in claim 1 wherein each end wall comprises a main inner web extending upwardly from said bottom to the top of said each wall, said means defining said recesses including means defining an opening through said main web for each of said recesses, each opening being bounded by opposed vertical edge sections extending downwardly from the top of said end wall at opposite sides of the upper seat and respectively spaced from the adjacent side of the upper seat by a distance exceeding the width of a support foot, each of said vertical edge sections respectively merging at its lower end with an inwardly and downwardly inclined edge section respectively constituting said first and second guide means, each of said inclined edge sections respectively merging at its lower end with a horizontal edge section respectively constituting a portion of said intermediate and lower seats. 7. The invention defined in claim 6 wherein said end wall further comprises an upper outer web extending downwardly from the top edge of said end wall in outwardly spaced, parallel relationship to said main web, wall sections extending between said main and outer webs along said vertical edge sections of said openings in said main web fixedly mounting said outer web upon said main web, and means mounting said upper seats on the inner side of said outer web. 8. The invention defined in claim 6 wherein the horizontal edge section defining a portion of said lower seat terminates at its end remote from the associated inclined section at an upwardly extending side edge establishing an end limit to sidewise movement of a support foot seated on said lower seat. 9. The invention defined in claim 7 further comprising a horizontal support web extending between and commonly secured to said main and outer webs in downwardly spaced, coextensive relationship to the horizontal edge section defining said intermediate seat, and a retaining lip projecting upwardly from said horizontal web at the end thereof remote from the associated inclined edge section to establish an end limit to sidewise movement of a support foot seated on said intermediate seat. 10. In an open-topped, stackable container having a retangular bottom and a pair of opposed end walls projecting upwardly at a slight outward inclination from opposite ends of said bottom whereby one of said containers may receive a like container in a nested, stacked relationship therein; the improvement comprising a plurality of outwardly projecting horizontally spaced and aligned support feet fixedly mounted on the outer side of each end wall adjacent the lower edge thereof, a plurality of horizontally spaced upper support seats fixedly mounted on the inner side of each end wall adjacent the upper edge thereof in respective vertical alignment with said support feet, each support foot including a horizontal web and a vertical flange projecting downwardly from said web along the outer edge thereof, each of said upper seats including a horizontal platform having a first upwardly projecting lip extending along the inner edge thereof and a second upwardly projecting lip extending along at least one side edge thereof, said first lips of said upper seats being vertically offset inwardly of the flanges of the vertically aligned support feet whereby, when the support feet of a first container are seated on the upper seats of a second like container, the flanges of the feet of the first container are located outwardly of the first lips of the upper seats of the second container to limit outward flexing of the end walls of said second container. 11. The invention defined in claim 10 further comprising means defining a first and a second support foot receiving recess on the inner side of each of said end walls extending downwardly from the top edge of the end wall respectively at opposite sides of each upper seat, means defining an intermediate support foot receiving seat at the lower end of each first recess vertically spaced below and aligned with the associated upper seat, and means defining a lower support foot receiving seat at the lower end of each second recess vertically spaced below and aligned with the associated intermediate seat. 12. The invention defined in claim 10 further comprising a guide surface located at one end of each of said end walls in spaced horizontal alignment with the platform of the adjacent upper seat, the last-mentioned platform having a second lip only at that side edge of said last-mentioned platform remote from said guide surface, and a downwardly inclined ramp on said last-mentioned platform at the side edge thereof adjacent said guide surface, the remaining upper seats having a second lip at both side edges of their respective plaforms.
