ABSTRACT:
A system for dispensing liquids, particularly a system for dispensing liquid soap through at least one hand-operated pump. The system includes a pump, a main reservoir for holding a first quantity of the fluid to be dispensed, and an auxiliary reservoir for holding a second and generally smaller quantity of fluid. The main reservoir, auxiliary reservoir, and pump are in fluid communication with one another through a coupling. The system and coupling are configured so that the fluid is drawn preferentially from the main reservoir, with fluid being drawn from the auxiliary reservoir only when the main reservoir is substantially emptied of fluid. Additionally, any fluid that is drawn from the auxiliary reservoir will be replenished automatically by fluid in the main reservoir as long as any fluid is present in the main reservoir.
