    [0033] FIG. 6: shows a schematic, three-dimensional illustration of the cosmetic brush device from FIG. 4 in an assembled state.

    [0034] FIG. 1 shows a cosmetic brush device 30 according to the invention (left) and three interchangeable cosmetic brushes 20a, 20b, 20c (right). The cosmetic brush device 30 shown is designed for the use of three cosmetic brushes 20a, 20b, 20c, but this is purely exemplary and may be adapted arbitrarily.

    [0035] The cosmetic brush device 30 comprises a brush casing 32 for insertion of at least one interchangeable cosmetic brush 20. The brush casing 32 has a substantially hollow cylindrical form with a guide groove 34 extending in the axial direction. The guide groove 34 extends over the entire length of the brush casing 32. In the embodiment shown, the guide groove runs rectilinearly. The guide groove 34 extends effectively as a longitudinal slot between two opposing end faces of the tubular brush casing 32.

    [0036] The guide groove 34 has several latching channels 35a, 35b, 35c, 35d at different positions along the longitudinal extent. In the exemplary embodiment shown, the latching channels 35a, 35b, 35c, 35d are formed substantially identically, but this is not obligatory. The latching channel 35a, 35b, 35c, 35d extends from the guide groove 34 as a branch initially vertically and then downward in a direction parallel to the guide groove 34.

    [0037] On the right-hand side of FIG. 1, three cosmetic brushes 20a, 20b, 20c are shown. Each cosmetic brush 20a, 20b, 20c comprises a base body 22 with substantially cylindrical form. Brush bristles 25 are arranged on an end face 24 of the base body 22 and form a brush head. The cosmetic brushes 20a, 20b, 20c shown in FIG. 1 differ inter alia in their brush head shape. Differently shaped brush heads fulfil different functions in make-up application.

    [0038] The base body 22 of the cosmetic brush 20a, 20b, 20c has a guide pin 28 protruding in the radial direction. This is superposed with a control portion 28a in the illustration of FIG. 1. The control portion 28a is situated at an end of the guide pin 28 facing away from the base body 22. The radially protruding guide pin 28 is designed for engagement in the guide groove 34. Its length in the radial direction thus corresponds approximately to the wall thickness of the brush casing 32.

    [0039] The cosmetic brush 20a shown at the top right in FIG. 1 additionally has a protective sleeve 26 which is displaceable in the axial direction. The interplay between the protective sleeve 26 and the base body 22 is illustrated in FIGS. 2a and 2b. The protective sleeve 26 is formed substantially hollow cylindrically and is arranged concentrically to the base body 22. The outer diameter of the protective sleeve 26 is smaller than the outer diameter of the base body 22. A control element 26a is arranged in a lower region of the protective sleeve 26. The control element 26a protrudes radially relative to the protective sleeve 26. When the protective sleeve 26 is connected to the base body 22 of the cosmetic brush 20a, the control element 26a engages in a recess of the base body 22 provided for this. When the control element 26a and the recess of the base body 22 are in engagement, the protective sleeve 26 can be moved relative to the base body 22 between a first position in which the protective sleeve 26 surrounds the brush bristles (not shown), and a second position in which the protective sleeve exposes the brush bristles (not shown).

    [0040] FIG. 3 shows three cosmetic brushes 20a, 20b, 20c in their state inserted in the brush casing 32. The brush casing 32 is indicated merely schematically. The cosmetic brushes 20a, 20b, 20c are for this inserted successively in the brush casing 32 so that the guide pin 28 is in engagement with the guide groove 34. Via the control portion 28a, the cosmetic brush 20a, 20b, 20c can be moved in the axial direction along the guide groove 34 up to a proposed position in the brush casing. By twisting the cosmetic brush 20a, 20b, 20c, the guide pin 28 is transferred into the latching channel 35a, 35b, 35c, 35d where it can engage. The cosmetic brush 20a, 20b, 20c is then in the latched state. The next cosmetic brush 20a, 20b, 20c is then also inserted in the brush casing 32 from above with the base body 22 at the front, and moved along the guide groove 34 to the desired position. The position depends on whether the cosmetic brush 20a, 20b, 20c is to be used or stowed. The cosmetic brushes 20a, 20b, 20c shown in FIG. 3 are all in a stowed state.

    [0041] FIG. 4 shows the components of a cosmetic brush device 30 according to the invention in a non-assembled state, with a lower cover element 39, a lower cosmetic brush 20c, a middle cosmetic brush 20b, a brush casing 32, an upper cosmetic brush 20a with protective sleeve 26, and an upper cover element 38. In order to assemble the components shown in FIG. 4, for example for transport of the cosmetic brush device 30, firstly the lower cosmetic brush 20c, then the middle cosmetic brush 20b and finally the upper cosmetic brush 20a are each inserted in the brush casing 32, moved along the guide groove 34 and engaged at a proposed position. Then the upper and lower cover elements 38, 39 may be placed on the brush casing 32. The upper and/or lower cover elements 38, 39 may additionally have an inwardly protruding pin (not shown) on the inside, which, on application of the cover element 38, 39 onto the brush casing 32, engages in the guide groove 39 and can be latched at a predefined position. In order to protect the brush head of the upper cosmetic brush 20a during application of the upper cover element 38, the use of a protective sleeve 26 may be provided. The protective sleeve 26 also prevents the escape of liquid make-up residue.

    [0042] In FIG. 5, the cosmetic brush device 30 is shown in a partially assembled state. The individual cosmetic brushes 20a, 20b, 20c are already arranged at the proposed positions. In a next step, the respective guide pins 28 are moved aside via the control element 28a so that, in this embodiment, the base body 22 performs a rotational movement counterclockwise. The guide pins 28 are thus transferred to the latching channels 35a, 35b, 35c, 35d in which they engage. The lower cosmetic brush 20c and the middle cosmetic brush 20b are completely received in the brush casing 32. The distance between the cosmetic brushes 20a, 20b, 20c in the brush casing 32 should be selected such that the brush head of a lower cosmetic brush 20c is not in contact with the base body 22 of a cosmetic brush 20b situated above it. In this embodiment, the upper cosmetic brush 20a is received solely with the lower part of the base body 22 in the brush casing 32. The insertion depth shown is however merely exemplary and may vary from embodiment to embodiment. The top cosmetic brush 20a is provided with a protective sleeve 26 since the brush bristles 25 protrude axially with respect to the brush casing 32. The protective sleeve 26 is therefore pushed over the brush bristles 25 from below, carefully pressing the brush bristles 25 together. In this position of the protective sleeve 26, the cover element 38 may be applied from above onto the brush casing 32 without damaging the brush head. Also, a lower cover element (not shown) may be pushed onto the brush casing 32 from below. The lower cover element may have an opening for the control element 28a which protrudes in a radial direction with respect to the brush casing 32. A sponge may also be inserted in the lower cover element 39.

    [0043] FIG. 6 shows the cosmetic brush device 30 in a fully assembled, transportable state. The brush casing 32 is closed at both end faces by cover elements 38, 39. The upper cover element 38 may have a pin (not shown) arranged on an inside, wherein, when the cosmetic brush device 30 is in an assembled state, the pin engages in the upper latching channel 35d. The upper cover element 38 is thus fixedly connected to the brush casing 32 and also secured against unintentional release. Three cosmetic brushes 20a, 20b, 20c are arranged inside the brush casing 32, and their respective guide pins 28 are in engagement with the guide groove 34. In order to latch the cosmetic brushes 20a, 20b, 20c at the proposed positions along the guide groove 34, the guide pin may be transferred into the latching channel 35a, 35b, 35c, 35d as a latching possibility. The cosmetic brushes 20a, 20b, 20c arranged in the brush casing 32 are thus protected compactly and as well as possible from external influences. The cosmetic brush device 30 may now easily be transported without the risk of damaging the brush heads or distributing make-up residue from the brush heads to surrounding transport goods.

    [0044] In order to use the cosmetic device 30 shown in FIG. 6 for the application of make-up, firstly the corresponding cosmetic brush 20a, 20b, 20c is extracted from the brush casing 32. If for example the middle cosmetic brush 20b is to be used, firstly the lower cover element 39 is removed. The lower cosmetic brush 20c is manually maneuvered out of the L-shaped latching channel 35c until the guide pin 28 is again in engagement with the guide groove 34 and may then be moved down and withdrawn from the brush casing 32. In the same way, firstly the middle cosmetic brush 20b and then the upper cosmetic brush 20a are removed from the brush casing 32. The second cosmetic brush 20b is then inserted from above, with the base body 22 first, into the brush casing 32 such that the guide pin 28 is in engagement with the guide groove 34, and the guide pin 28 is moved to the top latching channel 35d and inserted therein. When the cosmetic brush 20b is engaged in the top latching channel 35d, the cosmetic brush device 30 as a whole may be used as a cosmetic brush. The brush casing 32 forms the handle of the cosmetic brush 20b. According to the invention, therefore, the base body 22 of each cosmetic brush may be dimensioned very small since the cosmetic brush device 30 itself forms a handle.

    [0045] It should be ensured that the cosmetic brushes 20a, 20b, 20c are always moved through the brush casing 32 against the brush bristle direction, i.e. with the base body 22 first. After use of a cosmetic brush 20a, 20b, 20c, this is released from the latching position and may then be removed from the brush casing 32. The cosmetic brush device 30 may then be assembled either such that another cosmetic brush 20a, 20b, 20c is used, or the cosmetic brushes 20a, 20b, 20c are again stowed in the brush casing 32 so as to be transportable.

    [0046] The cosmetic brush device 30 described above has a high degree of flexibility and versatility, since the individual cosmetic brushes 20a, 20b, 20c may be replaced and exchanged arbitrarily.
