Document Type and Number:
Japanese Patent JPS5664974
Kind Code:
A
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. A retainer, acting on the upper end surface of the hub portion of the upper valve member, is mounted in axially fixed position within the inlet section of the through passage.
