Abstract

In a dispenser for dosing of at least one component received in a receiving compartment, a valve device, forming an inlet valve and an outlet valve associated with an outlet opening, is formed of at least two valve elements.

Claims

1. A dosing dispenser for the dosage of at least one material component received in a receiving compartment by means of a pumping unit connected therewith, comprising a piston, a cylinder, and a pumping chamber having inlet and outlet openings and being closable with a valve device, comprising:

an at least two-part valve device comprised of a first valve element closing an access opening from the container and having an opening for the material passage, a second valve element disposed thereon with a passage opening, and a third valve element disposed thereon, which preferably sealingly encloses a projection of the second valve element.

2. The dosing dispenser according to claim 1, wherein the second and third valve element is formed in two pieces or one piece.

3. The dosing dispenser according to claim 1, wherein the material of the valve elements is individually adjustable in terms of resilient flexibility or hardness.

4. The dosing dispenser according to claim 1, wherein the first valve element is a flat valve disc out of in particular elastic material having a central opening.

5. The dosing dispenser according to claim 4, wherein the first valve element is clamped with the second valve element and the side wall of the cylinder and forms the outlet valve of the valve device.

6. The dosing dispenser according to claim 5, wherein the outlet valve forms a flow channel between its upper end face and the bottom of the cylinder during the pressing out stroke of the pumping unit leading preferably to an annular channel.

7. The dosing dispenser according to one of the preceding claims, wherein the second valve element is formed trumpet-shaped in cross-section, and reaches through the bottom of the cylinder of the pumping chamber with a cylindrical projection forming a support for a biasing spring for the piston of the pumping unit with a radial bead and preferably serving as a central seat for the third valve element.

8. The dosing dispenser according to claim 1, wherein the outer diameter of the first and second valve elements is greater than the one of the third valve element, where preferably the peripheral edge of the first and second valve elements abuts at the cylinder wall of the pumping chamber.

9. The dosing dispenser according to claim 1, wherein the second valve element is formed at its upper or lower side with web-like radially encircling sealing rings.

10. The dosing dispenser according to claim 7, wherein the second valve element, preferably designed trumpet-shaped in cross-section, seals with the third valve element via a flange-like annular web provided at the peripheral edge with the lower side of the third valve arranged there above, and that the second valve element has apertures at a collar for the material passage at the lower side of the third valve element.

11. The dosing dispenser according to claim 1, wherein the third valve element is formed as a planar valve disc with a central opening which sealingly encloses the projection of the second valve element expediently.

12. The dosing dispenser according to claim 1, wherein the first valve element is provided with a central sealing plug suspended at radial or circumferential webs and preferably formed with an outer massive marginal bead for the definition of the valve device at the cylinder bottom.

13. The dosing dispenser according to claim 1, wherein the first valve element is formed as a blocking ball as a gravely acting blocking ball.

14. The dosing dispenser according to claim 13, wherein the blocking ball is formed of metal, glass, or hard rubber.

15. The dosing dispenser according to claim 13, wherein the second valve element has a collar having bridging radial webs or a cage blocking an access of the blocking ball in the upward direction in a sealing seat, in particular at the lower end of the projection.
