摘要： A plastic pallet including an upper plastic platform structure defining a load receiving surface and a lower plastic base structure defining the pallet support surface. The platform structure and the base structure are interconnected by leg or strut structures which coact with the platform structure and the base structure to define tunnels for the entry of material handling equipment. A series of upper beams are provided in the platform structure, a corresponding series of lower beams are provided in the base structure, and the struts interconnecting the platform structure and base structure serve to interconnect a respective upper beam with a respective lower beam so as to form of series of trusses within the pallet and optimize the rigidity of the pallet. The leg structures interconnecting the platform structure and the base structure are formed as clusters of small leg portions so as to minimize the size of the openings of the legs in the load receiving surface and in the pallet support surface and thereby preserve the planar integrity of these surfaces.

摘要： An improved laminated structural material; an improved method of forming a relatively rigid structural article such as a pallet; and an improved structural article using the invention laminated structural material. The invention article is formed by separately extruding relatively thin outer skin layers of a 25% talc filled polyethylene material and a relatively thick central core layer of an essentially virgin polyethylene material; bonding the layers together to form a composite laminate strip including the relatively thin talc filled outer skins and the thick central core layer of virgin polyethylene; severing the strip to form upper and lower sheets; heating the upper and lower sheets in an oven to place them in a flowable condition; delivering the upper and lower sheets respectively to upper and lower molds carried by upper and lower platens of a press; vacuum forming the upper and lower sheets respectively to the upper and lower molds; and thereafter bringing the platens of the press together to selectively knit or fuse the upper and lower sheets together to form the article. The article produced by the invention methodology costs only slightly more than an article formed of virgin polyethylene material and yet has vastly superior stiffness characteristics as compared to the virgin polyethylene article while retaining substantially all of the superior impact characteristics of the virgin polyethylene article.

摘要： A plastic pallet in which a plurality of beam assemblies are positioned beneath the plastic main body of the pallet to discourage warpage and failure of the pallet, especially in racked, loaded storage situations. The plastic structure of the pallet includes a planar platform section defining an upwardly facing load receiving surface and a plurality of legs extending downwardly from the platform section to define tunnels therebetween for receipt of the forks of a forklift truck. The beam structures extend in parallel fashion beneath the plastic structure. Each beam structure includes a central upstanding spine portion received in downwardly opening grooves defined in the bottoms of aligned legs, and a base portion which extends beneath the bottoms of the legs to provide a base on which each pallet may rest. Each beam structure is formed of a central tubular steel beam encapsulated by upper and lower plastic sheets which are fused together to totally enclose the steel beam and to form the base portion of the beam structure.

摘要： A plastic pallet of twin sheet construction formed in a vacuum thermal forming process. The upper sheet includes a series of downwardly extending hollow upwardly opening bosses arranged in staggered rows and the lower sheet includes a series of upwardly extending hollow downwardly opening bosses generally corresponding in size, number, shape and distribution pattern to the downwardly extending bosses on the upper sheet. The lower walls of the downwardly extending bosses are fused to the upper walls of the upwardly extending bosses in the thermal forming process so as to form a series of vertical columns extending between the upper and lower sheets and maintaining the sheets in fixed spaced relation. The pallet further includes a plurality of legs spaced circumferentially about the periphery of the pallet and depending downardly from the pallet. Each of the legs is formed of a downwardly extending portion of each of the sheets and forms an upwardly opening pocket opening in the upper face of the upper surface of the upper sheet to allow nesting of the pallet with other pallets of similar construction.
