Abstract: A transportable, multi-use, non-corrodible, non-metallic, polyolefin plastic storage container and integral pallet system for all-weather storage, handling and transportation of a variety of liquid or free-flowing solid materials, including hazardous and human consumable materials. A preferred embodiment comprises a rotationally molded vertically-oriented polyethylene container, polyethylene container cushion with reinforcing wood base, and a cup-like polyethylene pallet which receives and is integrally attached by thermal shrinkage or welding to said container by locking and reinforcing ribs. The pallet includes integrally molded two-way access tunnels for handling by a fork lift or pallet jack. The container and integral pallet system can be stacked two or more containers high and is self-aligning when stacked.
