  • Patent number: 5720229
    Abstract: Pallets (20) upon which objects (22) may be stacked and to which a wrapping sheet (24) of stretch film, or a strap (102), may be secured to retain the objects (22) in relation to the pallet (20), is disclosed. The pallet (20) has rails (30,32,34) with perpendicularly extending slats (36) secured thereto. The rail (30) has an anchor (66) about which the wrapping sheet (24) may be frictionally and wedgingly retained. The anchor (66) may include either an elongate channel (70,72) or tongue (66) or both. The rails (30,32,34) may have ends with corner supports (60) which cooperate with one another to prevent objects secured atop pallet (20) from moving laterally or longitudinally. Corner supports (60) also allow the pallets (20) to be stacked one on top another. The ends of the rails have grooves (90) formed therein so that the wrapping sheet (24) may be stretchably secured within the groove (90) thereby impeding the wrapping sheet (24) from moving upwardly when wrapped about the pallet (20).

  • Patent number: 5337681
    Abstract: A recyclable plastic pallet (220) upon which objects may be stacked is described. The pallet (220) comprises longitudinally spaced and laterally extending elongate front and back plastic rails (230, 232, 233, 234) having openings 258. The pallet also has laterally spaced and longitudinally extending elongate plastic slats (236) with apertures (254) therein. Retainers (238) are cooperatively received in the openings (258) of the rails (230, 232, 233, 234) and into the apertures (254) of the slats (236) to join the slats (236) and rails (230, 232, 233, 234) together to form pallet (220).

  • Patent number: 5115917
    Abstract: A corner support assembly for strengthening a corner of a container so that additional containers may be stacked on top thereof, is provided. The corner support assembly has first and second elongated members having cooperating attachment means so that the length of assembly can be adjusted commensurately with the length of the edge associated with the corner to be supported. Also included is an anchoring means for releasably attaching one of the members to an associated edge of the container such that the corner support assembly remains in juxtaposition with the edge of the container. Preferably, the anchoring means is a hook that affixes over a free edge of the container.
