In alignment with the central dispensing direction of the nozzle arrangement, either an aperture is provided in the housing through which aperture the droplet mist emerges from the discharge head if it is not sucked into the discharge channel by respiration of the user, or a liquid buffer is provided for receiving the droplet mist if it is not sucked into the discharge channel by respiration of the user.

Abstract: A liquid dispenser for cosmetic liquids having a liquid reservoir and an applicator. An outlet channel connects the reservoir to the applicator, the outlet channel being formed either valveless or with an outlet valve. The liquid dispenser has a pressure generating device which pressurizes liquid in the reservoir for conveyance through the outlet channel to the applicator. The pressure generating device has an air pumping device which feeds and an actuating pressure chamber. The actuating pressure chamber adjoins, and is separated from, the reservoir by a displaceable wall so that an overpressure in the actuating pressure chamber leads to an overpressure in the reservoir. The air pumping device has manual actuator, allowing air to be pumped into the actuating pressure chamber by the actuator, so that the overpressure in the actuating pressure chamber and in the reservoir rises sufficiently to convey liquid from the reservoir to the applicator.
