Abstract
Abstract Broadly, the present invention is directed to paperboard runners and paperboard pallets constructed therewith. One aspect of the invention comprises a paperboard pallet comprising an upper deck and a lower deck having a plurality of runners interposed therebetween and affixed to each of said decks. Each of the runners comprises a sheet of paperboard that has been folded into a rectangular form having top and bottom walls, a pair of sidewalls, and a central vertical wall (e.g., the two ends of the sheet pressed together) interposed between the sidewalls. The top wall has openings. The central wall has quarter-round cut-outs located at the longitudinal ends of the top wall cut-out areas. The top wall openings are adapted to receive flaps having central slots cut in them. The flaps are selected from: flaps formed from said runner top wall; flaps cut from an upper deck attached to said runner; or flaps formed from a rectangular insert which has a pair of end slotted flaps, which insert fits into said top wall opening with said end slotted flaps folding downwardly into said quarter-round cut-outs. Another aspect of the present invention comprises the runners described herein. A further aspect of the present invention is an alternate paperboard runner which comprises a sheet of paperboard that has been folded into a rectangular form by one end being folded to form a first bottom wall, a first sidewall, a first top wall, and a second sidewall; and the other end being folded into an "S" configuration to form a central vertical wall, a part second top wall which lays against said first top wall, and a part second bottom wall which lays against said first bottom wall. The top wall has openings. The central vertical wall has quarter-round cut-outs located at the longitudinal ends of said top wall cut-out areas. The top wall openings are adapted to receive flaps which have central slots cut in them. The flaps are selected from: flaps formed from said runner top wall; flaps cut from an upper deck attached to said runner; or flaps formed from a rectangular insert which has a pair of end slotted flaps which insert fits into said top wall opening with said end slotted flaps folding downwardly into said quarter round cut-outs. This paperboard pallet embodiment can be made collapsible for shipment and storage, yet it can be simple and quickly assembled into a strong, lightweight, disposable pallet.
