US 2024/0239587 A1 · LIQUID DISPENSER

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.
