A dispenser for soap lather has a vessel for a larger supply of liquid soap and a tank for a smaller supply of liquid soap and for a body of air above the smaller supply. One or more bellows are used to pump compressed air into the upper portion of the tank when a user desires to-obtain a batch of lather. The compressed air expels a certain quantity of liquid soap from the tank into a lather generator and the lather generator further receives some compressed air to form a batch of lather which is dispensed into or onto the hands of a user. When the bellows expands or expand, they can draw air into or along the outlet of the lather generator to retract any remnants of lather. Alternatively, a discrete pump can be provided to blow out any remnants from the lather generator in response to or during expansion of the bellows. The discharged quantity of liquid soap is replenished in the tank by way of an adjustable conduit connecting the vessel with the tank.
