19. The mixing device of claim 18, wherein the passages have a diameter of from 0.2 mm to 1 mm at the flow exit.

20. The mixing device of claim 18, wherein the passages have a diameter of from 0.3 mm to 0.6 mm at the flow exit.

21. The mixing device of claim 15, wherein the passages have a diameter of from 0.1 mm to 10 mm at a flow exit.

22. The mixing device of claim 17, wherein the passages have a diameter of from 0.1 mm to 10 mm at a flow exit.

23. The mixing device of claim 11, wherein all diameters of the passages at a flow exit of a mixer plate are the same.

24. The mixing device of claim 11, wherein diameters of the passages at a flow exit of the mixer plates decrease toward the outlet.

25. A dispenser, wherein the dispenser comprises one or more mixing devices according to claim 11 and one or more preparations, at least one of the one or more preparations comprising at least two phases.

26. The dispenser of claim 26, wherein the at least one preparation comprising at least two phases is a cosmetic preparation.

27. A method of mixing one or more preparations at least one of which has at least two phases, wherein the method comprises mixing the one or more preparations with the mixing device of claim 11.

28. The method of claim 27, wherein the at least one preparation having at least two phases is a cosmetic preparation.

29. The method of claim 27, wherein the at least one preparation having at least two phases comprises particulate material.

30. The method of claim 28, wherein the at least one preparation having at least two phases comprises particulate material.

Description

[0058] FIG. 1 depicts a sketch and illustration of a mixing device according to the invention with 3 mixer plates (1) in which multiple passages (2) are provided. The mixing device comprises at the preparation entry a mixer attachment (3) with two openings (4) through which the two preparations (5, 6) are pressed into the mixing device.

[0059] FIG. 2 shows a mixer plate (1) with two geometrically different passages (2).

[0060] The preferred shape of a cone segment is shown on the left. Another possible shape is shown on the right. For all possible shapes, it is essential that the diameter of the passages (2) at the flow exit (2d) is smaller than the diameter of the passages at the flow entry (2a).

[0061] FIG. 3 shows 4 mixer plates (1) one above the other in a dispenser. The preparations (5, 6) are pressed into the mixer plate (1) from below. Said preparations flow through the passages (2) of the first mixer plate. The passages (2) of the first mixer plate have a diameter of 0.5 mm at the flow exit (2d).

[0062] The second mixer plate has a spacing (7) of 0.55 mm from the first mixer plate.

[0063] The passages (2) of the second mixer plate have a diameter of 0.45 mm at the flow exit (2d), the passages (2) of the third mixer plate have a diameter of 0.4 mm at the flow exit (2d), and the passages (2) of the fourth mixer plate have a diameter of 0.35 mm at the flow exit (2d).

[0064] Consequently, there is realized not only narrowing within the respective passages (2) of a mixer plate (1) but also narrowing from one mixer plate to the next, this always being in the flow direction toward the discharge (8).

[0065] FIG. 4 shows a dispenser (9) with 4 mixer plates (1). The preparations (5, 6) are transported to the exit (8) of the dispenser through the mixer plates (1) via the ascending tube.
