Abstract

The invention relates to a dosing device. The dosing device comprises a storage container with a storage chamber disposed therein for accommodating a filling material, a dosing container with a dosing chamber disposed therein, an outlet with an outlet opening for dispensing the filling material, a closure member by means of which the outlet opening can be closed, and a valve wherein the valve is able to assume a dispensing position and a dosing position.

First claim

The invention claimed is:

1. A dosing device comprising
a storage container with a storage chamber for accommodating a filling material,
a dosing container with a dosing chamber,
an outlet with an outlet opening for dispensing the filling material, and
a valve,
wherein the valve is able to assume a dispensing position and a dosing position,
wherein the valve, in the dosing position, opens a dosing connection between the dosing chamber and the storage chamber and shuts an outlet passage from the dosing chamber to the outlet opening and the valve, in the dispensing position, shuts the dosing connection and opens the outlet passage,
wherein the dosing device further comprises
a valve seat for accommodating the valve with the valve seat having a cylindrical shape with a side surface, and
wherein a connecting conduit between the dosing container and the valve seat opens out into the side surface of the valve seat,

wherein the dosing device comprises a closure member, with which the outlet opening can be closed off,
wherein the closure member is coupled to the valve in such a way that rotation of the closure member displaces the valve between the dosing position and the dispensing position,
wherein the closure member is coupled to the valve and the outlet in such a way that rotation of the closure member locks the closure member with the outlet as long as the valve is in the dosing position and that rotation of the closure member unlocks the closure member with the outlet, when the valve is in the dispensing position.

2. The dosing device according to claim 1 , wherein the valve is rotatably disposed in the valve seat of the dosing device.

3. The dosing device according to claim 2 , wherein the closure member is configured as a rotary closure member and the closure member is non-rotatably connected to the valve.

4. The dosing device according to claim 2 , wherein a rotary movement of the valve is limited by a protrusion or cut-out formed on the valve seat, which cooperates with a cut-out or a protrusion formed correspondingly in the valve.

5. The dosing device according to claim 3 , wherein the closure member is provided with a first appendage or recess, which cooperates by positive fit in a direction of rotation with a second appendage or recess formed on the valve.

6. The dosing device according to claim 1 , wherein the outlet has a substantially cylindrical shape, with a web extending in a circumferential direction being provided on the outlet, and the closure member being provided with a lug, which, at least in one position of rotation, latches behind the peripheral web for locking along a cylinder axis of the outlet.

7. The dosing device according to claim 1 , wherein the storage chamber and the dosing chamber are arranged in such a way that at least a part of the filling material can be filled from the storage chamber into the dosing chamber by tilting the dosing device around a pivot axis.

8. The dosing device according to claim 1 , wherein the valve has a casing comprising four openings divided into two pairs of openings, wherein the two openings within each pair are associated with one another so that through connections are formed within the casing only between those openings that are associated with one another.

9. The dosing device according to claim 8 , wherein the valve has a cylindrical shape, so that the valve has a first and a second end face as well as the casing and an inner space, wherein the first end face comprises the first opening and the second end face comprises the second opening and the casing comprises the third and the fourth opening, and wherein a partition wall is disposed in an inner space.

10. The dosing device according to claim 9 , wherein the inner space comprises a first and a second space, the first space being separated from the second space by the partition wall, and the first space being accessible from the outside of the valve through the first and the third opening, and the second space being accessible from the outside of the valve through the second and the fourth opening.

11. The dosing device according to claim 10 , wherein the first space is not accessible from the outside through the second and the fourth opening, and the second space is not accessible from the outside through the first and the third opening.

12. The dosing device according to claim 1 , wherein the storage container and the dosing container are formed as one piece.

13. The dosing device according to claim 1 , wherein the dosing container comprises a fill level indicator.

14. The dosing device according to claim 1 , wherein the closure member is configured as a rotary closure member, wherein simultaneous rotation of the rotary closure member and pressing down in the axial direction is required for unlocking.

15. The device of claim 13 , wherein the dosing chamber has a cylindrical shape and the fill level indicator comprises at least one curved marking line with circular form which indicates a certain filling level of the filling material in the dosing chamber at different pivot angles.

16. The device of claim 15 , wherein the filling level indicator comprises more than one curved marking line configured in the form of concentric partial circle sections.
