Abstract: A pallet assembly includes an upper deck and a lower deck spaced by a plurality of columns. The weight of the pallet is reduced without significant reduction in strength by providing only a single cross beam in each of the upper and lower reinforcement members and orienting them perpendicular to one another. The reinforcement members are minimized for weight reduction and for improved performance in heat tests. The peripheral rail of the upper reinforcement member is reduced such that it rests on only an inwardly open recess on an inner corner of each of the corner columns. This reduces the size and weight of the upper reinforcement member, while still providing support to the upper deck. Additionally, the peripheral rails of both the upper and lower decks are reduced in length such that either ledge does not directly support them while the pallet is stored on a rack.

Abstract: A collapsible container includes a base, and pairs of opposed side and end walls that are pivotally mounted on the base. When the side walls are pivoted to a raised position against inward flanges defined on the end walls, latch members on the side walls engage complementary shoulders defined on end wall flange projections to thereby lock the side walls relative to the end walls. Each latch member includes a base portion mounted proximate to a respective lateral edge of the side wall, a lever arm portion extending away from the side wall's lateral edge, and an intermediate portion having a camming surface and adjacent shoulder with which to engage the respective end wall flange projection. When raised, edge portions of each side wall are received in recessed shelves defined in the base while the side wall's inner face simultaneously engages cantilevered stop members defined in the base.

Abstract: Polyolefin-based pallets capable of passing standard pallet flammability tests are prepared by molding the pallet or one or more subassemblies thereof, of a polyolefin molding resin containing a flame retardant package containing magnesium hydroxide, and optionally alumina trihydrate, and zinc borate. The flame retardants may be supplied as a master batch at a concentration higher than that desired in the pallet or subassembly, in a polyolefin-compatible polymer, and result in pallets having a significantly lower heat release rate.

Abstract: A pallet assembly includes an upper deck and a lower deck spaced by a plurality of columns. In one embodiment, the columns are snap-fit into the upper deck and the lower deck. The weight of the pallet is reduced without significant reduction in strength by providing only a single cross beam in each of the upper and lower reinforcement members and orienting them perpendicular to one another. The reinforcement members are minimized for weight reduction and for improved performance in heat tests. The peripheral rail of the upper reinforcement member is reduced such that it rests on only an inwardly open recess on an inner corner of each of the corner columns. This reduces the size and weight of the upper reinforcement member, while still providing support to the upper deck. Additionally, the peripheral rails of both the upper and lower decks are reduced in length such that either ledge does not directly support them while the pallet is stored on a rack.
