Abstract
Abstract A slip pallet formed as a square or rectangular sheet of a synthetic resin of selected types of polyolefin. The sheet is proportioned to fit upon a platen lift and includes tabs at each edge to be gripped when the platen is thrust underneath the sheet or the sheet is pulled upon or pushed off from the platen. The slip pallet will ordinarily carry loads of boxes formed as interlocking layers and an important feature of the invention resides in providing a sheet having a greater coefficient of friction at the upper surface whereon the boxes are placed, than at the undersurface which is contacted by the platen. The polyolefin material forming the slip pallet includes a filler material which may be either fibers and/or particles, the fibers being used to enhance the tensile strength of the pallet and the particles being used as an extender to reduce the amount of synthetic resin to be used.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
174 words
A slip pallet for holding a load of cardboard boxes, or the like, and carried by a platen which slides underneath the slip pallet and its box load for loading and unloading the same onto and off from the platen, said pallet comprising: a tough, pliable sheet of single thickness of synthetic thermoplastic resin having a thickness in the range of approximately 20 to 125 mils; a central area whereon the box load is placed; a tab means alongside at least one edge of this central area folded upwardly along the edge of the central area to be gripped and held whenever the platen is moving underneath the pallet from the tab side; a modified upper surface at the central area adapted to enhance the contact thereof with the cardboard surfaces of the box load upon the pallet sufficient to increase the static frictional resistance between the box load and the pallet to a degree which exceeds the sliding frictional resistance between the pallet and the platen, and a filler blended into the resin.
Claim 2
Dependent Claim
