Patent Images
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 cylinder that defines a pumping chamber having inlet and outlet openings;
a piston configured to selectively move within the pumping chamber;
a container configured to hold material interconnected to the pumping chamber, wherein material from the container is adapted to travel through the pumping chamber upon selective actuation of the piston; and
a valve device comprising;
a first valve element that selectively closes an access opening from the container, the first valve element having an opening that selectively allows material passage from the container to the pumping chamber,second valve element defined by a collar having a cylindrical projection extending therefrom that defines a passage opening that communicates with the opening of the first valve element, the second valve element disposed on the first valve member, anda third valve element disposed on the second valve element that sealingly engages the cylindrical projection of the second valve element.

13. 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 cylinder that defines a pumping chamber having inlet and outlet openings; a piston configured to selectively move within the pumping chamber; a container configured to hold material interconnected to the pumping chamber, wherein material from the container is adapted to travel through the pumping chamber upon selective actuation of the piston; and a valve device comprising; a first valve element that selectively closes an access opening from the container, the first valve element formed as a gravity-actuated blocking ball, second valve element defined by a collar having a cylindrical projection extending therefrom that defines a passage opening that receives the blocking ball when the plunger is moved from the pumping chamber, which also opens the first valve element, and a third valve element disposed on the second valve element that sealingly engages the cylindrical projection of the second valve element, wherein the cylindrical projection extends through the second valve element. - View Dependent Claims (14, 15)
