  • Patent number: 4330071
    Abstract: A dispensing device for discharging a liquid or pasty product from a container comprises a valve housing, provided with a vertical through passage for said product, including an upper inlet section for connecting the valve housing to an outlet of a container, a lower outlet section, and an intermediate valve chamber, defined between two resilient disk-like valve members which are spaced apart in the longitudinal direction of said passage and provided with thickened hub portions by which they are mounted on a supporting pin, located centrally within the valve chamber. In order to facilitate a simplified and less expensive manufacture and assembly of the device, the supporting pin is formed integrally with the valve housing which, as a whole, is formed in one single piece. The supporting pin projects upwardly into the valve chamber from a partial bottom wall of the valve housing. Near its lower end, supporting pin has a shoulder on which the hub portion of the lower valve member rests.
