Transportable multi-use storage container and pallet system

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. Additional features include a recessed manway and buttressed closure, recessed channels for a combination pressure and vacuum release valve, recessed off-set ballvalve with reinforced tunnel and sloping drain lip, an offset sump with bottom sloping to the sump for near 100% drainage without tipping, tie-down ears and wear pads on the pallet feet. The circumferential reinforcing and locking ribs prevent bowing of the container at its mid-point and the cup pallet provides double-walled protection for the container at the lower 25-75% of the container height. The container and integral pallet system complies with Department of Transportation ("DOT") regulations for exempt steel hazardous waste containers, and the material of which complies with the federal Food and Drug Administration ("FDA") regulations for storage and transportation of human consumable materials.
