Abstract

The invention relates to a dispensing device, particularly a dispensing head proposed for preferably cosmetic liquid. A simple, tightly closing structure of an outlet valve is achieved in that a valve element is injected onto a wall and/or lies thereon with its entire surface or flat surface when the valve is closed and/or the valve element covers an outlet opening on the flat side. Alternatively or in addition, the valve element is pretensioned into a closed position when the valve is closed.
