Load-contacting Surface Formed By Bonded Plastic Sheets Patents (Class 108/57.27)
  • Patent number: 10377527
    Abstract: A composite pallet is made of concrete. The concrete material can include various concrete mixtures, such as Fiber Reinforced Concrete (FRC) or an Engineered Cementitious Composite (ECC). It also can include microspheres. The concrete material can be cast in a mold or formed via an extrusion process and then cured. The pallet components can include a core material that can form various voids or cavities. The core material can include polystyrene foam, and the foam forms a honeycomb, which is then filled with the concrete material. The concrete material can also be dyed to create different colors to identify the pallets. The pallets can further include plastic and/or rubber bumpers on the corners and/or edges to prevent or minimize chipping. The resulting pallet can be cured using carbon dioxide (CO2) curing which reduces the cure time to about an hour or less.

  • Patent number: 8573137
    Abstract: A hollow upper deck panel for a plastic pallet has a solid top surface and is produced by forming a tubular hot plastic parison and directing the parison between blow mold sections to form upper and lower sheets for the deck panel. The lower sheet is blow molded by pressured air within the parison into a mold section to form spaced inverted U-shaped open ribs projecting upwardly and with top portions fused to the upper sheet. The upper sheet is blow molded by the air around retractable blades to form spaced closed double wall ribs projecting downwardly between the open ribs and have bottom portions fused to the lower sheet. The closed double wall ribs extend transversely to the open ribs and have end portions fused to the open ribs. The support structure for the upper deck panel defines spaces for receiving parallel spaced forks of a forklift truck.

    Abstract: A reinforced plastic pallet comprises a twin sheet deck structure and three twin sheet runner structures which are fused to the underside of the deck to create three parallel spaced-apart footprints, the spacing between them forming one set of forklift openings. The deck is fabricated from two thermoformed plastic sheets which are peripherally joined together. The lower sheet is formed with upwardly extending spacer knobs which are fused to the under surface of the top sheet to further join the two sheets together. A frame of reinforcing beams is encapsulated into the interior space of the upper deck. The runner structures are also of twin sheet construction and some of them contain reinforcing rods. The runner structures, although they have flat footprints, are generally “W” shaped to provide two additional forklift openings at 90° from the primary forklift openings between the runner structures.
