  • Patent number: 4597338
    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.

  • Patent number: 4577759
    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.

  • Patent number: 4508237
    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.

  • Patent number: 4426001
    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.
