Abstract
Abstract A pallet is disclosed in which the load is carried on a surface formed, at least partly, by a corrugated panel which may be of fiberboard or other construction. The corrugations of the panel may be partly or completely filled on one or both sides with rigid plastic foam, or other organic or inorganic compound, including the filling of strips at spaced points along the major surfaces of the panel, the strips oriented at right angles to the corrugations. Support members in the form of spaced runners or posts are provided to offset the panel, which constitutes a deck, from the surface against which the pallet is to rest, or from the bottom wall of a container. The spacing of the support members themselves, and the spacing they afford between bottom support surface and panel, is sufficient to permit four-way entry of the prongs of a pallet-lift or fork-lift truck. Rigid plastic foam extends into the corrugations of the panel at the points of fastening of the support members thereto, and if desired, in any or all of the remaining flutes of the corrugated panels as required to provide the strength needed for the particular pallet use.
