Abstract
A double walled waste grease collecting tank for use in collection system in which the collecting tank is partially submersed in a hot water bath to soften or melt grease at the container walls to facilitate emptying the solid or semi-solid collected grease. The double walled collecting tank has fill openings in its outer wall adjacent its bottom which are normally closed by removable plugs. The plugs are removed to enable hot water to enter the space between the double walls when the tank is submerged into the hot water bath, then replaced when the tank is emptied. Closable vent openings provided adjacent the top of the outer wall are opened to permit rapid filling and emptying the air space between the double walls, and closed when the tank is emptied.
