Abstract: A two-level stacking container is formed with a square bottom, a pair of first like sidewalls projecting upwardly from two opposed sides of the bottom and a pair of like second sidewalls projecting upwardly from the two remaining sides of the bottom. The first and second sidewalls are formed with a stacking web having top and bottom edges each having vertically spaced alternating upper and lower edge sections so arranged that when two containers are stacked first walls on first walls and second walls on second walls, the containers are in a high level stacked relationship; and when stacked first walls on second walls and second walls on first walls, the containers are in a low stacked relationship.

Abstract: A pallet is assembled from two identical pallet halves of a molded plastic material, such as polypropylene. Each pallet half is formed with a rigid, rectangular, load supporting platform having symmetrically disposed rows of support posts and latching leg assemblies projecting vertically from one surface of the platform. The posts and legs are so located and dimensioned that the legs on one pallet half can be inserted into the posts of the other to snap lock the two halves into assembled relationship. Spaced skirt portions along each edge of the platforms engage those of the other pallet half to define forklift tine receiving openings in each side of the pallet.

Abstract: A three-level stacking container is formed with uniformly spaced openings extending downwardly from the upper edge of each of two opposed sidewalls of the container. The sidewalls take the form of a relatively thin planar web in which the openings are formed and each web is formed with three horizontal, vertically spaced shelves projecting forwardly from the rear edge of each opening. Stacking feet on the outer side of the web may be supported on a selected set of one of the three sets of shelves on an underlying like container, access to the two lower shelves being achieved by passing the feet of the upper container downwardly in the openings forwardly of the shelves. The lowermost of the three shelves constitutes the bottom edge of the opening and the front end of the next uppermost shelf projects forwardly beyond the front end of the uppermost of the three shelves.

Abstract: A multi-level stacking container is constructed in a manner such that two like containers may be stacked one upon the other in either of a high-level or low-level stacked relationship wherein the end walls of the upper container are respectively stacked upon upper or lower portions of the underlying container or in an intermediate stacked position wherein the side walls of the upper container are parallel to the end walls of the lower container, that is stacked crosswise to each other. This provides the possibility of stacking the container of the present invention with prior art containers of different configuration which utilize the cross-stacking arrangement.

Abstract: A collapsible container includes opposed side walls hingedly connected along their upper and lower edges respectively to the bottom of a rectangular peripheral upper rim and to the bottom of the container along opposed side edges of the rim and bottom. End walls are hingedly connected along their upper edges to the rim along its opposed end edges. Webs along the end edges of the side walls and bottom engage the end walls to locate the end walls in their vertical erected position relative to the bottom, and projecting tabs on the end walls are received in mating recesses in the web to maintain the bottom and side walls against flexing when the container is erected. The upper rim is adapted to receive a stacking rail formed on the container bottom to enable stacking of the containers either in their erected or collapsed configuration.The container may include a pair of cover panels hinged along their respective outer side edges to the tops of the side edges of the rim.

Abstract: A square nesting and stacking container wherein each wall of the container has a plurality of feet near the bottom of the container and a plurality of saddles near the top of the container. The saddles are located directly above the feet so that the feet will engage the saddles of a similarly oriented container of identical construction and support the same in a stacked relationship. There are clearances between the saddles so that when one container is turned 90.degree. with respect to another, it may be lowered into a nested relationship with the latter without interference because the feet will enter and pass through the clearances of the lower container.

Abstract: A multilevel stacking container is nestable in a like container when in like end to like end relationship thereto and stackable in an intermediate level relative to the underlying container upon reversal to a like end to unlike end relationship. A stacking shelf is hingedly mound on each end of the container between a stored position, which accommodates nesting or intermediate level stacking of like containers, and a support position which establishes a high level stacking configuration in which the upper of two stacked containers is stably supported at a substantially higher level relative to the underlying container as compared to the intermediate level stacked relationship.

Abstract: 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.

Abstract: A four-level stacking container includes bale members mounted on each of two opposed end walls by pivot pins received in slots in the end walls. The configuration of the slots are such that the bale member pivot pins may be located in either of at least two stable rest positions within the slots and the bale member may be pivoted to either of two rest positions relative to the end walls for each stable rest position of the pivot pin. The four rest positions thus established accommodate the stacking of a like container in a first container at any one of four different elevations relative to the first container.

Abstract: 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.
