Abstract: A droplet dispenser for dispensing cosmetic or pharmaceutical liquids in the form of individual droplets, having a medium reservoir with a first and second medium chambers, which are isolated from one another for separately storing two media. The medium chambers are connectable to produce a combined liquid. The droplet dispenser has a discharging opening and, downstream of the discharging opening, a droplet forming contour in order to create droplets which detach from the droplet forming contour as soon as the droplets have reached a defined volume. The droplet dispenser has a pump device between the medium reservoir and the discharging opening, wherein the pump device has a variable-volume pump chamber for delivering combined liquid. The pump device has an inlet valve on the entry side and an outlet valve on the exit side.

Abstract: A liquid dispenser for dispensing a cosmetic or pharmaceutical liquid produced by mixing two starting liquids. The liquid dispenser has at least two liquid reservoirs for holding the two starting liquids and a discharge opening, and at least one pump device by which liquid can be delivered from the liquid reservoirs to the discharge opening. The dispenser has one intake opening for removing the liquid, via the at least one pump device, at one end of each liquid reservoir, and one intake tube extending from the intake opening to a bottom end of each liquid reservoir. Further, one filling opening is provided at the bottom end of each of the liquid reservoirs.
