Description

The invention relates to a spreading device for the targeted application of hair color-changing agents to the outer coat with at least one comb prong to be coupled to the outlet opening of a dispenser containing the coloring agent for dividing strands of hair to be colored and for spreading the coloring agent, with a receiving bore for placing on the dispenser at the foot of the prong is provided.

In a device of this type described in DE-GM 81 19 211, the applicator has two flat comb teeth arranged in parallel spacing for dividing a strand of hair to be colored. In the floor area between the teeth, a passage leads to the inside of the dispenser, through which the dye preparation can exit. In this way, it should be possible to apply the smallest amounts of hair dye preparations to narrow strands in a targeted manner without the strands to be dyed having to be separated and lifted off individually using a comb. However, the known device is so complex and so complicated to handle that it is usually only in the hairdressing. business can find application.

To dye individual strands of hair in home use, perforated hoods are used, through which individual strands are to be drawn at will with a hair strand pulling needle or crochet hook for the purpose of separate coloring. A targeted application of the hair color-changing agents only on the top hair, which is both for reasons of hair protection as well of the cosmetic expression can be meaningful, however, is not possible in this way.

The invention has for its object to provide a device for the targeted application of hair color-changing agents on the top coat, preferably for single use, to be placed on existing closure systems or container openings and equally suitable for home use according to expenditure and handling. The solution according to the invention is characterized for the spreading device of the type mentioned at the outset with a comb tine to be coupled to the outlet opening of a coloring agent container and at the foot of the tine receiving hole for placement on the dispenser outlet, characterized by the formation of the receiving hole for being plugged onto a standard part for parting the hair and / or application tip of a colorant dispenser designed to apply the colorant. Improvements and further refinements of the invention are specified in the subclaims.

Accordingly, the invention provides an application device for applying hair color-changing agents to the top coat or strands of top coat, which is designed so that it can be attached, in particular attached, to existing dispensers in home use and in single use, without any moving parts being required. Although the device according to the invention manages with a single tine serving for dividing, applying and / or spreading, the equipment with two or more tines is advantageous for handling, since this simplifies the division of individual strands. Optimal shielding of the hair areas adjacent to the treated strand of hair and optimal protection of the scalp from mechanical damage is guaranteed, when the tines are bent symmetrically away from each other in pairs and have rounded, especially reinforced, tips.

In particular when using a pair of comb teeth, it is advantageous for a good transition of color to the hair if the bridge between the adjacent teeth is continuously curved, in particular semicircular. The outlet channel of the spreading device can then be provided in the region of the bridge between the tines and there have at least one through opening, in particular as a nozzle. According to a further invention, the outlet channel can also be extended into one or more tines so that it opens onto the respective inner surface of the tine intended for spreading.

If, particularly for home use, it is desired to dye individual sections of hair pulling away from the head with only one hand, it may finally be expedient to equip the spreading device with only one hook-shaped prong with an outlet channel opening onto the inner surface of the hook curve. Here too, guide grooves can be provided on the inner surface of the tine, which act as additional lateral guide elements.

• Fig. 2 Längsschnitte von drei von Fig. 1 abweichenden Verbis 4 streichvorrichtungen; und
• Fig. 5 einen Längsschnitt durch eine auf eine Applikationsspitze aufgesetzte hakenförmige Verstreichvorrichtung.

Further details of the invention are explained on the basis of the schematic representation of exemplary embodiments. Show it:

• Fig. 1 is a patch to an application tip Verstreich- _'device in longitudinal section;
• Fig. 2 shows longitudinal sections of three Verbis 4 deviating devices deviating from Fig. 1; and
• 5 shows a longitudinal section through a hook-shaped spreading device placed on an application tip.

Fig. 1 shows an overall designated 1 closure with application tip 2 of a colorant dispenser in a section parallel to the longitudinal axis 3. The application tip 2 has an outlet 4 suitable for dispensing the colorant contained in the container, not shown, at the tapered longitudinal end 5 and is per se to the apex Hair and trained to apply the colorant. A spreading device according to the invention, designated overall by 6, is placed on the application tip 2. The coupling can be achieved in the simplest case by frictional engagement in a bore 8 provided in the base 7 of the spreading device 6. With such a plug connection, the coloring agent comes primarily directly from the outlet opening 4 onto a strand of hair to be treated, while the spreading device only serves to distribute the coloring agent on the strand of hair and / or other parts of the hair and scalp from contact with the coloring agent or shield the outlet opening 4.

In the exemplary embodiment according to FIG. 1, it is provided that the spreading device 6 is provided symmetrically with a pair of comb teeth 9 bent away from one another with rounded tips 10. Due to the continuously curved outward inclination Compartments or tines 9 ensure optimal shielding of adjacent hair areas and excellent protection of the scalp from mechanical damage. A special scalp-friendly training is obtained when the tips 10 of the tines 9 are rounded and reinforced.

In Fig. 1 it is also indicated that the coupling between the application tip 2 and the bore 8 in the foot 7 of the coating device 6 in addition to mere frictional engagement by molded tools, e.g. Threads and cams or by the snap ring 11, can be produced. Further forms of coupling between the spreading device 6 and the application tip 2 are shown in FIGS. 2 to 5. In principle, the coupling here consists of a blind bore 12 for inserting the free end 13 of the application tip 2.

From the blind bore 12, the outlet channels formed differently in the exemplary embodiments according to FIGS. 2 to 5 emanate. In the case of FIG. 2, the outlet channels are formed by at least one, in particular nozzle-shaped, bore 14 in the region of the bridge 15 between two prongs 9. The size of the holes 14 is adapted to the consistency or toughness of the hair color-changing, in particular cream-like, agent used. A continuously curved, in particular semicircular, bridge 15 between. The adjacent tines 9 serve to adapt to the natural conditions of a strand of hair drawn between the tines 9.

According to FIG. 3, an outlet channel 16 with a mouth 17, which is extended into the tine 9, can be provided on the inner surface of the respective tine 9. The outlet channel 16 can be along its length also have more than one mouth 17, in particular at least one mouth bore 14 (similar to FIG. 2) can be provided in the region of the bridge 15 between adjacent tines.

In the exemplary embodiment according to FIG. 4, guide grooves or grooves 18 are provided on the inner surface of at least one of the tines 9 in addition to at least some of the features according to FIGS. 2 and 3.

In the device according to FIG. 5, a shape of the spreading device 6 which differs from the exemplary embodiments according to FIGS. 1 to 4 is indicated in principle. The device 6 here has essentially a hook shape, the outlet channel 16 starting at the blind bore 12 designed to be placed on a customary application tip 2 to the bottom region 19 or also at one or more other locations on the remaining inner surface 20 of the hook 21, and opening there . The hook shape of the spreading device 6 according to FIG. 5 offers the advantage of being able to dye individual strands of hair with one hand pulling away from the head. In use, the hair is guided in the arcuate inner surface 20 of the hook 21 and the coloring agent is applied from the mouths 22 of the outlet channel 16.
