Abstract
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.
