Abstract
Abstract An assembly for collecting and disposing of waste solvents in a manner to meet safety requirements of municipalities. The assembly includes a waste tank and an open-top container for receiving and supporting the waste tank. The container has a greater internal volume that does the waste tank so that, when the waste tank is in the container, a space surrounds the waste tank. Such space is adapted to receive and trap any leakage or overflow of the solvent from the waste tank during use of the assembly. The waste tank has a first port for receiving waste solvent and a second port for allowing the waste solvent to be pumped out of the waste tank. Liquid level sensors are provided on the waste tank for sensing the solvent therein at different levels. The container has brackets for positioning the waste tank on the bottom of the container, and the container has casters to allow the assembly to be easily shifted from place to place.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
A waste solvent receptacle comprising: a closed waste tank having a top provided with a solvent inlet port, said waste tank adapted to receive solvent through the port; and a mobile container having an open top, a fluid impervious bottom, and wall structure secured to and extending upwardly from said bottom, said waste tank being removably received in said container through said open top and being supported on said bottom, said waste tank top includes a top wall and means on the topwall thereof for defining a pair of handles on said waste tank to facilitate removal of said waste tank from said container, said container having a volume greater than the volume of the waste tank so that a space is formed in surrounding relationship to the waste tank and substantially surrounding a major portion of said waste tank when the waste tank is centrally located in the container, whereby the container can receive leakage and overflow solvent from the waste tank, said top wall having a solvent outlet port thereon and spaced from the inlet port thereof for pumping said solvent out of said waste tank and electrical level sensor means for controlling the solvent level within said waste tank.
