Abstract

A dispensing apparatus simultaneous discharges at least two flowable components of a multi-component mass from different storage volumes. The dispensing apparatus includes a passive mixing unit having a central mixing passage extending along a flow direction and being configured to guide the components mixed with one another, and including at least two inlets opening into the central mixing passage, the inlets being associated with the same storage volume and open into the mixing passage at different positions along the flow direction.

First claim

The invention claimed is:

1. A dispensing apparatus, for the simultaneous discharge of at least two flowable components of a multi-component mass from different storage volumes, the dispensing apparatus comprising:
a passive mixing unit having a central mixing passage extending along a flow direction and being configured to guide the components mixed with one another, including at least two inlets opening into the mixing passage, the inlets being associated with the same storage volume and open into the mixing passage at different positions along the flow direction, and having at least one further inlet opening into the mixing passage.

2. The dispensing apparatus in accordance with claim 1 , further comprising a packaging film forming a part of the inlets.

3. The dispensing apparatus in accordance with claim 2 , wherein the mixing unit has at least one inlet passage adjoining directly at one of the storage volumes, the inlet passage branching at least once into the at least two inlets and the packaging film at least partly forming the storage volumes and the at least one inlet passage.

4. The dispensing apparatus in accordance with claim 2 , wherein the packaging film at least partly forms the central mixing passage.

5. The dispensing apparatus in accordance with claim 1 , further comprising a cover film at least partly forming a part of the inlets.

6. The dispensing apparatus in accordance with claim 5 , further comprising a packaging film forming a part of the inlets and a sealing film arranged between the packaging film and the cover film.

7. The dispensing apparatus in accordance with claim 6 , wherein the mixing unit has at least one inlet passage adjoining directly at one of the storage volumes, the inlet passage branching at least once into the at least two inlets and the sealing film bounding at least the central mixing passage, the at least one inlet passage and at least one of the in lets.

8. The dispensing apparatus in accordance with claim 7 , further comprising a packaging film forming part of the inlets, the mixing unit having at least one inlet passage adjoining directly at one of the storage volumes, the inlet passage branching at least once into at least two of the inlets and the packaging film at least partly forming the storage volumes and the at least one inlet passage and the sealing film having at least one perforation connecting the at least one inlet formed by the cover film to the inlet passage formed by the packaging film.

9. The dispensing apparatus in accordance with claim 7 , further comprising a packaging film forming part of the inlets, the mixing unit having at least one inlet passage adjoining directly at one of the storage volumes, the inlet passage branching at least once into at least two of the inlets and the packaging film at least partly forming the storage volumes and the at least one inlet passage and the sealing film having at least one perforation connecting the at least one inlet formed by the cover film to the central mixing passage formed by the packaging film.

10. The dispensing apparatus in accordance with claim 8 , further comprising at least one activation pin disposed so as to generate an activation of at least one of the perforations.

11. The dispensing apparatus in accordance with claim 9 , further comprising at least one activation pin disposed so as to generate an activation of at least one of the perforations.

12. A dispensing apparatus, for the simultaneous discharge of at least two flowable components of a multi-component mass from different storage volumes, the dispensing apparatus comprising:
a passive mixing unit having a central mixing passage extending along a flow direction and being configured to guide the components mixed with one another, and including at least two inlets opening into the central mixing passage, the inlets being associated with the same storage volume and open into the mixing passage at different positions along the flow direction, and at least one inlet passage adjoining directly at one of the storage volumes, the inlet passage branching at least once into the at least two inlets.

13. The dispensing apparatus in accordance with claim 12 , wherein the at least one inlet passage and the central mixing passage extend at least substantially in parallel.

14. The dispensing apparatus in accordance with claim 12 , further comprising a packaging film forming a part of the inlets.

15. The dispensing apparatus in accordance with claim 12 , further comprising a cover film at least partly forming a part of the inlets.

16. A dispensing apparatus, for the simultaneous discharge of at least two flowable components of a multi-component mass from different storage volumes, the dispensing apparatus comprising:
a passive mixing unit having a central mixing passage extending along a flow direction and being configured to guide the components mixed with one another, and including at least two inlets opening from different sides into the central mixing passage, the inlets being associated with the same storage volume and opening into the mixing passage at different positions along the flow direction.

17. The dispensing apparatus in accordance with claim 16 , wherein the inlets associated with the same storage volume alternatively open from the sides into the central mixing passage.

18. The dispensing apparatus in accordance with claim 16 , further comprising a packaging film forming a part of the inlets.

19. The dispensing apparatus in accordance with claim 16 , further comprising a cover film at least partly forming a part of the inlets.
