Abstract

See full text

A liquid storage tank assembly includes a baffle member and a tank assembly. The baffle member includes a generally helical or spiral shaped portion. The baffle member defines a spiral flow path between inlet and outlet openings of the tank assembly. When the baffle member is positioned within the tank and the tank assembly holds a volume of a first liquid, input of a supply of a second liquid at the inlet to the tank assembly forces the first liquid along the spiral flow path and out of the tank assembly exit without substantial mixing of the first and second liquids before substantially all of the first liquid has been dispensed.
