Abstract
Abstract An integrally formed plastic pallet from an injection molding die. The top portion of the pallet for carrying the load is separated from the bottom portion through which the pallet is supported, by spacing portions. The top and bottom portion have rib portions arranged with recesses between them. The top and bottom ribs are displaced from each other in conjunction with their recesses, so that the top ribs lie above the bottom recesses, whereas the bottom ribs lie beneath the top recesses. The recesses are at least as wide as their respective ribs.
