Abstract: A cardboard pallet that is constructed of a laminate, such that the top and bottom of the pallet have two plies of material, with the plies mutually orthogonal to one another. The pallet is assembled by attaching stringers and ribs to an inner skin, rotating the inner skin 90° and attaching to an outer skin, and wrapping the inner and outer skins about the stringers. Apertures on the end regions and portals in the bottom region of the pallet accommodate forklift tines or wheels on various material-handling devices. The apertures may be formed to create wear cuffs, to lengthen the life of the pallet.

Abstract: A unitary dunnage device for use with a "singled out" pallet unit being transported within a van, trailer or container. The device includes a pair of void fillers, each being dimensioned and configured to fit within a respective lateral void, existing between the pallet and the container's sidewalls. The void fillers are structurally united and supported in spaced horizontal relation by a suspension structure. The suspension structure has a median portion overlying the pallet unit, and end portions extending from the sides of the pallet unit to the container's sidewalls. The void fillers are attached to and depend from the underside of a respective end portion.

Abstract: A dunnage device expandable from a compact flat stack into a vertically extending cellular slab. A plurality of elongated strips is stacked and assembled in co-extensive relation. Each strip has a median portion, opposing end portions, and opposing outer end extremities. A transverse fold line is provided between the median portion and each end portion, across each strip. The strips are attached to each other at their outer end extremities to form pairs; the pairs are attached to each other along adjacent median portions. When the stack of attached strips is expanded, a plurality of serially connected, horizontally oriented, rectangular cells is formed. Means for suspending the cellular slab is disclosed. A foldable, integral backing board, in combination with the cellular slab, is also disclosed.

Abstract: A hollow door panel construction includes a rectangular frame of predetermined thickness assembled from side and end members defining an elongated enclosure. Within the enclosure are corrugated paperboard strips, having a width equal to the predetermined thickness. The strips are variously formed and attached to define a plurality of horizontal cell rows, vertically stacked to fill the framed volume. Each cell row spans the internal width of the frame, and includes a centrally positioned short-walled brace cell straddled on either side by a long-walled lateral cell. To complete the panel construction, thin sheets abut and are secured to the opposite faces of the frame and to the outer edges of the strips.

Abstract: An expandable honeycomb slab constructed from sheet material of corrugated paperboard, for filling load voids within a container carrying articles of freight. A plurality of horizontal cell rows, each containing a central diamond-shaped cell straddled by a pair of square-shaped cells, is stacked in vertical relation. Vertically adjacent corners and apexes of the cells are interconnected so as to allow vertical expansion of the suspended cellular array under its own weight. The vertically aligned, centrally positioned diamond-shaped cells provide vertical support and horizontal rigidity for the array, effectively preventing the honeycomb slab from assuming an hourglass configuration.
