[0026] FIG. 9 shows a front view of they embodiment of the invention according to FIG. 1.

[0027] Reference is first made to FIGS. 1 to 4, which show an embodiment of the invention in different views. The device has a housing for receiving a hair dye, wherein the housing 1 is substantially cuboidal in shape. A handle 2 is integrally formed on or attached to one of the side surfaces of the housing 1 with a longitudinal axis A, which is shown in FIG. 4. The respective side surface is also referred to hereinafter as the side surface of the housing 1 facing the handle 2. In the embodiment shown, the handle 2 is arranged on the housing 1 such that the longitudinal axis L of the handle 2 is angled with respect to a longitudinal direction R of the housing 1, as can be seen in particular in FIG. 4. The handle 2 may further be provided with a handle sleeve which can be slid onto the handle 2 in order to be able to adapt the handle 2 in terms of its cross-section or its length in a more haptically pleasant manner to the hand of an operator.

[0028] A cover 3 is removably attached to an upper side of the housing 1, for which clip fasteners 4 are provided in the embodiment shown, in each of which a resilient tab of the cover 3 detachably snaps into a corresponding pocket of the housing 1. However, the cover 3 can also be pivotally attached to the housing 1 so that it can flip up and expose the interior of the housing. Immediately prior to applying the hair dye to the scalp hair of a person to be treated, the housing 1 can be opened by removing or flipping up the cover 3 to introduce a hair dye into the housing 1. The hair dye is generally formed from a composition of a t least two components which are mixed together immediately prior to application. This preparation will usually take place outside the housing 1, with the ready-prepared hair dye being filled into the housing 1. Afterwards, the housing 1 can be closed again by putting on or closing the cover 3.

[0029] As can be seen from FIGS. 2 and 3, a supply element 5 is provided, which in the exemplary embodiment shown is designed as a feed plate, which also forms the housing base of the housing and is arranged within the housing 1 so to be movable in the direction of the cover 3. During this movement, hair dye is conveyed in the direction of dispensing openings so that the feed plate serves as a supply element 5, as will be explained in more detail. For this purpose, the handle 2 in the embodiment shown is designed in a pincer-like manner with a stationary upper part 7 and a lower part B pivotable on the upper part 7, wherein the lower part 8 is pivotably connected to the supply element 5. For further explanation of the movability of the supply element 5, reference is also made to FIG. 5. In order to enable a translational movement of the supply element 5 designed as a feed plate with a constant angular position within the housing 1, the feed plate is guided with the aid of a parallelogram guide, which in the present case is realized with the aid of a parallelogram joint. For this purpose, the lower part. 8 has a first parallelogram link 8a and a second parallelogram link 8b, which are fastened on the one hand to the upper part 7 of the handle 2 so as to be pivotable about the pivot axes S1 and S2, and on the other hand to the feed plate about the pivot axes S3 and S4, as can be seen in particular from FIG. 2 and FIG. 5c. A spring element 9 ensures the return of the supply element 5 to its lower position as shown in FIG. 5c. The operation can thus be performed with a single hand, namely with that hand which also holds the handle 2. By closing the fist, the pivotable lower part 8 can be actuated, whereby the supply element 5, designed as a feed plate, is moved in the direction of the dispensing openings 6 (FIG. 5b) with a constant angular position.

[0030] A parking piece 10 is further attached to the second parallelogram link 8b, which is intended to allow the device to be parked in an upright position when not in use.

[0031] On its upper side, the cover 3 has webs 11 extending perpendicularly to the longitudinal direction R, which form groove-like hair receptacles 12 between them. The webs 11 can also have different heights in the course of their longitudinal extension, as can be seen for example in FIG. 1. The groove-like hair receptacles 12 thereby form a sequence of hair receptacles 12 arranged next to one another in the longitudinal direction R of the housing 1, which each open towards the exterior of the housing for the insertion of regions of hair, wherein in a first set of the hair receptacles 12 the hair receptacles 12 are each connected to the interior of the housing via dispensing openings 6 for dispensing hair dye, and hair-dye-free hair receptacles 12 of a second set are arranged between the hair receptacles 12 of the first set, which hair receptacles 12 do not have these dispensing openings 6 and are thus closed with respect to the interior of the housing. In the embodiment shown, the dispensing openings 6 are arranged along a side edge of the cover 3 extending in the longitudinal direction R of the housing. That side surface of the housing 1 which extends along this side edge is subsequently referred to as the front side surface 15 and is of concave design, as can be seen for example in FIG. 3.

[0032] Above the cover 3, a brush lever 13 is provided, which can be seen clearly in FIG. 1, for example, which can be pivoted about a lever pivot axis S5 extending transversely to the longitudinal direction R of the housing 1 (see FIG. 4) from a position close to the cover, in which the brush lever 13 at least partially covers the hair receptacles 2 with respect to the exterior of the housing and the brushes 18 of the brush lever 13 project into the hair receptacles 12, into a position far from the cover, in which the brush lever 13 exposes the hair receptacles 12 with respect to the exterior of the housing. In addition, in the exemplary embodiment shown, the brush lever 13 is displaceable in its position close to the cover in the direction of a sliding axis S6 (see, for example, FIG. 1 or FIG. 4) from an active position, in which the brushes 18 project into the dispensing area of the dispensing openings 6, to an inactive position, in which the brushes 18 are spaced apart from the dispensing area of the dispensing openings 6. In the embodiment shown, the sliding axis S6 is also the lever pivot axis S5 and extends at an acute angle to the side surface of the housing 1 facing the handle 2, with the acute angle opening in the direction of the front side surface 15 of the housing 1, as can be seen in FIG. 4, for example. In this way, the brush lever 13 is also moved away from the front side surface 15 at the same time as it is pivoted up, preventing unintentional contact of the head hair with the color-bearing brushes 18 of the brush lever 13. The brushes 18 were indicated in FIG. 4 and FIG. 9.

[0033] FIG. 6 shows a side view of the embodiment of the invention according to FIG. 1 as seen from the side facing away from the handle. FIG. 7 shows a side view of the embodiment of the invention according to FIG. 1 as seen from the side facing towards the handle. FIG. 8 shows a rear view of the embodiment of the invention according to FIG. 1, and FIG. 9 shows a front view of the embodiment of the invention according to FIG. 1.

[0034] In the following, the operation of the device according to the invention will be described. In the initial position of the color application on a region of hair, the device is held with the front side surface 15 of the housing 1 as close as possible to the scalp of the person to be treated. The concave design of the front side surface 15 and the angled position of the handle 2 facilitate this positioning of the housing 1 close to the head.

[0035] In this initial position close to the head, a region of hair a so-called passis picked up and placed in the hair receptacles 12. During the insertion of the region of hair into the hair receptacles 12, the brush lever 13 is in its position away from the cover so as not to interfere with the insertion of the region of hair. When the region of hair is inserted into the cover 3, the individual strands are separated from each other by the webs 11 and distributed among the hair holders 12.

[0036] After the region of hair has been inserted, the brush lever 13 can be pivoted about the lever pivot axis S5 into its position close to the cover, in which the brush lever 13 at least partially covers the hair receptacles 12 relative to the outside of the housing and the brushes 18 project into the hair receptacles 12. A first return spring is tensioned in the process. Subsequently, the brush lever 13 can be moved in the direction of the sliding axis S6 into its active position, in which the brushes 18 project into the dispensing area of the dispensing openings 6. Here, the second return spring is tensioned, with an operating element 14 facilitating this displacement movement. The pivoting movement as well as the sliding movement can thereby preferably be carried cut with the thumb of a single hand, namely with that hand which also holds the handle 2. Preferably, the brush lever 13 can be locked in its active position to enable the operator to continue working without having to manually fix the brush lever 13 in its active position.

[0037] By actuating the lower part 8 of the handle 2 and the resulting pivoting of the feed plate 5 in the direction of the dispensing openings 6, hair dye is fed from the interior of the housing to the dispensing openings 6 of the hair receptacles 12 of the first set, where it leaves the interior of the housing and is picked up by the relevant, channel-like hair receptacle 12 of the first set, where it washes around the strand inserted in the relevant hair receptacle 12 in the region of the dispensing opening 6. The hair receptacles 12 of the second set, on the other hand, remain hair dye-free. The housing 1 is subsequently slowly removed from the scalp of the treated person with the aid of the handle 2, wherein, on the one hand, the strands are formed by dividing the treated region of hair among the hair receptacles 12, and, on the other hand, the strands inserted in the hair receptacles 12 of the first set are pulled through the hair dye and thus dyed with the assistance of the brushes 18. This movement can be accompanied by a slight twisting of the housing 1. The brushes 18 of the brush lever 13 thereby improve the color application to the region of hair to be colored on the one hand and enable excess hair dye to be wiped off on the other hand. In order to improve the wiping off of excess hair dye and to prevent dripping of hair dye, color wipers 17 can also be provided, which are designed as knobs or pins and are arranged along the side edge of the cover 3 extending in the longitudinal direction R of the housing 1 (see FIG. 9).

[0038] After the hair dye has been applied and the device has been pulled off along the treated section of hair, the locking mechanism can be released by actuating a pin 16, wherein the second return spring moves the brush lever 13 along the sliding axis S6 into its inactive position, and the brush lever 13 can subsequently be pivoted upwards, supported by the first return spring, about the lever pivot axis S5 into its position remote from the cover. The device is now ready for the application of hair dye to a further section of hair.

[0039] It is also conceivable to design the cover 3 in an interchangeable manner and to make the cover 3 different, for example with different widths of the hair receptacles 12, or also with a variable clear cross-section of the hair receptacles along their longitudinal extension, in order to realize different effects in the colored hair.

[0040] The device facilitates the shaping of strands and the application of hair dye with consistent quality, and enables faster and cleaner work. In particular, the tedious shaping of strands and brushing them with hair dye can be omitted. The process of applying the hair dye can also be carried out more quickly, and dripping of the hair dye or the like can be largely avoided, so that clean work is made possible.
