Abstract

A dispensing apparatus for a flowable component includes a storage container, an applicator and a closure element. The storage container has a storage chamber configured to receive the component, an outlet flange and a component outlet. The applicator has a component inlet and a dispensing opening, and is connected to the storage container by the outlet flange establishing a connection between the component outlet of the storage container and the component inlet of the applicator. The closure element is independent from the applicator, and configured to selectively adopt a closed position and a dispensing position, the component outlet is closed in the closed position and open in the dispensing position, and is configured to be coupled to the applicator so as to be brought from the closed position into the dispensing position by a rotation of the applicator in a connection direction with respect to the storage container.

First claim

The invention claimed is:

1. A dispensing apparatus for a flowable component, the dispensing apparatus comprising:
a storage container having a storage chamber configured to receive the component, an outlet flange, a component outlet and a middle axis extending through the component outlet;
an applicator having a component inlet and a dispensing opening,
the applicator being connected to the storage container by the outlet flange establishing a connection between the component outlet of the storage container and the component inlet of the applicator; and

a closure element independent from the applicator, the closure element configured to selectively adopt a closed position and a dispensing position, the component outlet of the storage container being closed in the closed position and being open in the dispensing position,
the closure element being configured to be coupled to the applicator so as to be brought from the closed position into the dispensing position by a rotation of the applicator in a connection direction with respect to the storage container, and
the closure element being configured to be rotated about an axis of rotation on changing from the closed position into the dispensing position, the axis of rotation being arranged spaced apart from the middle axis of the storage container.

2. The dispensing apparatus in accordance with claim 1 , wherein the applicator is configured to be removed from the storage container after a rotation against the connection direction and the closure element is configured to be brought from the dispensing position into the closed position by the rotation against the connection direction.

3. The dispensing apparatus in accordance with claim 1 , wherein the connection between the applicator and the storage container is established by the rotation of the applicator in the connection direction with respect to the storage container for setting the dispensing position of the closure element.

4. The dispensing apparatus in accordance with claim 3 , wherein the applicator has an outer thread and the outlet flange of the storage container has a corresponding inner thread.

5. The dispensing apparatus in accordance with claim 4 , wherein the outer thread and the inner thread are multi-start threads.

6. The dispensing apparatus in accordance with claim 1 , wherein the closure element has an entrainer pin and the applicator has a corresponding entrainer recess which are configured and arranged such that, on a placement of the applicator onto the storage container, the entrainer pin dips into the entrainer recess such that the closure element is entrained on a rotation of the applicator with respect to the storage container.

7. The dispensing apparatus in accordance with claim 1 , wherein the closure element has a recess which, in the dispensing position of the closure element, is positioned such that the component can flow out of the storage chamber via the component outlet and the recess to the component inlet of the applicator.

8. The dispensing apparatus in accordance with claim 7 , wherein the storage chamber has a guide pin and the recess of the closure element is configured and arranged such that the guide pin is arranged in the recess both in the closed position and in the dispensing position.

9. The dispensing apparatus in accordance with claim 1 , wherein the closure element is configured as a closure disc, is the closure disc being at least partly arranged in a closure recess of the storage container.

10. The dispensing apparatus in accordance with claim 9 , wherein the closure recess has a retaining element cooperating with the closure element such that the closure element is maintained in the closure recess in a captive manner after insertion into the closure recess.

11. The dispensing apparatus in accordance with claim 9 , wherein the closure element has an edge at an outer contour, the edge cooperating with the retaining element of the storage container.

12. The dispensing apparatus in accordance with claim 9 , wherein the closure element has an introduction inclination.

13. A dispensing apparatus for a flowable component, the dispensing apparatus comprising:
a storage container having a storage chamber configured to receive the component, an outlet flange and a component outlet;
an applicator having a component inlet and a dispensing opening,
the applicator being connected to the storage container by the outlet flange establishing a connection between the component outlet of the storage container and the component inlet of the applicator; and
a closure element independent from the applicator, the closure element configured to selectively adopt a closed position and a dispensing position, the component outlet of the storage container being closed in the closed position and being open in the dispensing position,
the closure element being configured to be coupled to the applicator so as to be brought from the closed position into the dispensing position by a rotation of the applicator in a connection direction with respect to the storage container, and
the closure element having an entrainer pin and the applicator having a corresponding entrainer recess which are configured and arranged such that, on a placement of the applicator onto the storage container, the entrainer pin dips into the entrainer recess such that the closure element is entrained on a rotation of the applicator with respect to the storage container.

14. The dispensing apparatus in accordance with claim 13 ,
wherein the applicator is configured to be removed from the storage container after a rotation against the connection direction and the closure element is configured to be brought from the dispensing position into the closed position by the rotation against the connection direction.

15. The dispensing apparatus in accordance with claim 13 ,
wherein the connection between the applicator and the storage container is established by the rotation of the applicator in the connection direction with respect to the storage container for setting the dispensing position of the closure element.

16. The dispensing apparatus in accordance with claim 13 ,
wherein the closure element is configured as a closure disc, is the closure disc being at least partly arranged in a closure recess of the storage container.

17. A dispensing apparatus for a flowable component, the dispensing apparatus comprising:
a storage container having a storage chamber configured to receive the component, an outlet flange and a component outlet;
an applicator having a component inlet and a dispensing opening,
the applicator being connected to the storage container by the outlet flange establishing a connection between the component outlet of the storage container and the component inlet of the applicator; and
a closure element independent from the applicator, the closure element configured to selectively adopt a closed position and a dispensing position, the component outlet of the storage container being closed in the closed position and being open in the dispensing position,
the closure element being configured to be coupled to the applicator so as to be brought from the closed position into the dispensing position by a rotation of the applicator in a connection direction with respect to the storage container,
the closure element having a recess which, in the dispensing position of the closure element, is positioned such that the component is capable of flowing out of the storage chamber via the component outlet and the recess to the component inlet of the applicator, and
