What is being proposed is a lever spray pump for dispensing a cosmetic liquid. The lever spray pump has a flexible section which can be deformed for the pumping of the liquid. The pump has a manually operable actuation element in order to deform the section for pumping. The pump has an air valve for a container associated with the pump. The air valve is embodied in a single piece with the section and is opened automatically upon deformation of the section or operation of the pump. Preferably, the section is pretensioned in the built-in state with non-actuated pump.
