Abstract

A dispensing apparatus includes a storage container having an outlet flange with a component outlet which is at least partly surrounded by an inlet flange. The inlet flange is configured to adopt a closed position and a dispensing position with respect to the outlet flange. A change from the closed position into the dispensing position is carried out by a rotation of the inlet flange with respect to the outlet flange. The component outlet is arranged at a cylindrical jacket surface of the outlet flange. The first component outlet is closed by the inlet flange in the closed position of the inlet flange. In the dispensing position, a connection is established by a crossover passage between the first component outlet and a dispensing opening.

First claim

The invention claimed is:

1. A dispensing apparatus for a flowable component, the dispensing apparatus comprising:
a storage container having a first storage chamber configured to hold a first component and having a first component outlet; and
a dispensing element connected to the storage container and having a dispensing opening,
the storage container having an outlet flange, the outlet flange comprising the first component outlet and a cylindrical jacket surface at least partly surrounded by an inlet flange of the dispensing element,
the inlet flange being rotatable with respect to the outlet flange, and
the inlet flange being configured to adopt a closed position with respect to the outlet flange, in the closed position, the first component outlet being closed, and the inlet flange being configured to adopt a dispensing position, in the dispensing position, the first component outlet being configured to dispense the first component via the dispensing opening, and the inlet flange being configured to change from the closed position into the dispensing position by a rotation of the inlet flange with respect to the outlet flange,
the first component outlet being formed within the cylindrical jacket surface of the outlet flange,
the first component outlet being closed by the inlet flange in the closed position of the inlet flange, and
an inner contour of the inlet flange having a first crossover passage configured and arranged such that the first crossover passage establishes a connection between the first component outlet and the dispensing opening in the dispensing position of the inlet flange by being a part of a flow path of the first component between the first component outlet and the dispensing opening.

2. The dispensing apparatus in accordance with claim 1 , wherein the outlet flange has a peripheral abutment surface, the peripheral abutment surface being aligned in the direction of the dispensing opening and configured such that a counter-surface of the inlet flange abuts the abutment surface in an entire region of the crossover passage.

3. The dispensing apparatus in accordance with claim 2 , wherein the abutment surface bounds the collar in the direction of the dispensing opening.

4. The dispensing apparatus in accordance with claim 1 , wherein the outlet flange has a peripheral collar, the peripheral collar forming a latch connection between the outlet flange and the inlet flange with a corresponding groove in the inlet flange.

5. The dispensing apparatus in accordance with claim 1 , wherein
the storage container has a second storage chamber configured to hold a second component and has a second component outlet disposed at the jacket surface of the outlet flange,
the second component outlet is closed by the inlet flange in the closed position of the inlet flange,
an inner contour of the inlet flange has a second crossover passage, the second crossover passage being configured and arranged so as to establish a connection between the second component outlet and the dispensing opening in the dispensing position of the inlet flange, and
the dispensing element is a mixer having a mixer housing and a mixing element disposed within the mixer housing, with the inlet flange being a part of the mixer housing.

6. The dispensing apparatus in accordance with claim 5 , wherein the mixing element and the outlet flange are one piece.

7. The dispensing apparatus in accordance with claim 5 , wherein the first and the second component outlets are oriented in opposite directions.

8. The dispensing apparatus in accordance with claim 7 , wherein the inlet flange is configured to rotate 90° with respect to the outlet flange to change the closed position into the dispensing position.

9. The dispensing apparatus in accordance with claim 5 , wherein the mixer is a static mixer.

10. The dispensing apparatus in accordance with claim 9 , wherein the outlet flange and the mixing element are separate components and the outlet flange has a cut-out in the direction of the dispensing opening into which an end region of the mixing element is configured to dip.

11. The dispensing apparatus in accordance with claim 10 , wherein the cut-out of the outlet flange and the end region of the mixing element are configured such that the end region of the mixing element only dips into the cut-out in a defined position.

12. A dispensing apparatus for a flowable component, the dispensing apparatus comprising:
a storage container having a first storage chamber configured to hold a first component and having a first component outlet; and
a dispensing element connected to the storage container and having a dispensing opening,
the storage container having an outlet flange, the outlet flange encompassing the first component outlet and having a cylindrical jacket surface at least partly surrounded by an inlet flange of the dispensing element,
the inlet flange being rotatable with respect to the outlet flange, and
the inlet flange being configured to adopt a closed position with respect to the outlet flange, in the closed position, the first component outlet being closed, and the inlet flange being configured to adopt a dispensing position, in the dispensing position, the first component outlet being configured to dispense the first component via the dispensing opening, and the inlet flange being configured to change from the closed position into the dispensing position by a rotation of the inlet flange with respect to the outlet flange,
the first component outlet being disposed at the cylindrical jacket surface of the outlet flange,
the first component outlet being closed by the inlet flange in the closed position of the inlet flange, and
an inner contour of the inlet flange having a first crossover passage configured and arranged so as to establish a connection between the first component outlet and the dispensing opening in the dispensing position of the inlet flange,
the storage container having a second storage chamber configured to hold a second component and has a second component outlet disposed at the jacket surface of the outlet flange,
the second component outlet being closed by the inlet flange in the closed position of the inlet flange,
an inner contour of the inlet flange having a second crossover passage, the second crossover passage being configured and arranged so as to establish a connection between the second component outlet and the dispensing opening in the dispensing position of the inlet flange, and
the dispensing element being a mixer having a mixer housing and a mixing element disposed within the mixer housing, with the inlet flange being a part of the mixer housing.
