Abstract

Device for dispensing an air-liquid mixture, such as foam, comprising a liquid container and an operating unit (1), which unit comprises at least a concentric air pump (2) and liquid pump (3), which each comprise a piston chamber (4, 9) with a piston (5, 10) which is displaceable therein and an inlet and discharge, and operating component (11) for operating the two pumps (2, 3), which component is integral with the liquid piston (10) and comprises an outflow channel (15) with a dispensing opening, while shut-off means, which make it possible to suck up air or liquid, respectively, and dispense them, are present in the inlet and discharge of the pumps (2, 3), the air pump (2) comprising a double-acting shut-off device which can be operated actively by the operating component (11) and shuts off both the inlet of air to the air pump (2) and shuts off the discharge of air therefrom, and the air piston (5) is an air piston (5) which can be moved freely at least over a small distance with respect to the operating component (11).
