Abstract: A sanitary waste grease and fat disposal system and apparatus includes a novel sanitary storage unit for storage and handling of waste fatty materials, a tank truck for transportation of such materials, and equipment for transferring the stored materials to the truck for transportation to a fatty material processing plant. The sanitary storage unit is an enclosed storage bin of sealed, sanitary construction with a top opening for introduction of fatty materials and a bottom, valved outlet for connection to a hose for pumping to a tank truck for transportation. The top of the storage unit has a spring loaded lid which opens by operation of a pedal and has an interior wall with a strainer for trapping larger contaminating materials from the fatty materials being collected. The contents is kept fluid by a thermostatically controlled heating element in the bottom of the storage unit.

Abstract: A sanitary apparatus for storage and transportation of waste fatty materials for reprocessing consists of a sealed storage bin of novel and sanitary construction. The unit consists of a fluid tight box shaped bin having an open top and tapering downward toward a closed bottom. The bin is reinforced with a rectangular angle iron frame at the bottom in which are positioned casters for support and ease of lateral movement. The bin is reinforced by a rectangular channel frame about half way up its height. The top of the bin is surrounded by a rectangular angle iron flange which supports a cover having a base flange fitting the top flange on the bin. The cover flange includes an inwardly facing channel fitting the rear flange on the top of the bin and also has locating pins which extend through mating holes in the top flange of the bin. The top part of the cover slopes downward toward the front and has a lid hinged thereon which has a pull latch and is spring loaded toward open position.
