Abstract
A tank with spin molded unitary polymeric walls. An upper portion of the walls have graduations indicating the amount of liquid required to fill the tank to each of the graduations, and the walls are sufficiently light transmissive to afford visual observation of the level of the liquid in the upper portion of the tank. The tank has a generally funnel shaped portion adjacent its lower end decreasing in area from its upper portion to its lower end, a liquid passage opening at its lower end, a transverse wall at said upper end, and an air passage opening adjacent its upper end. A frame is provided for supporting the tank on a horizontal surface with its upper end uppermost.
