A dispensing device for a preferably cosmetic liquid as well as a method for the manufacture thereof are proposed. A lasting and tight joining of two materials is achieved while allowing for simple manufacture by pretreating the surface of the first material by means of plasma treatment or irradiation in a desired joining area in order to form radicals there or to break up the polymer chains of the first material, and by then injecting the second material directly against the first material. Another aspect consists in covering the first material with a second material for joining with another material or component.

Dispensing device

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.
