Definitions

• the invention is directed to a device for the continuous delivery of a hair dye onto the hair of a person with a memory for the hair dye made of a first porous material within a housing and inserted into the first porous material, which is connected to the latter by capillary connection a second porous material.
• a comb for the continuous delivery of a liquid substance onto the hair and scalp of animals or humans is known (EP 0 157 032).
• This comb has a cavity in a narrow back of the comb with a handle on one side, in which there is a first porous material for receiving and storing the liquid substance.
• a large number of tines, which engage in the first porous material and are made of a second porous material, are in capillary connection with the first porous material storing the liquid substance in the cavity.
• the liquid substance can be applied to the hair and, above all, the skin via the free ends and side surfaces of the tines.
• This comb is particularly suitable for treating animals with insecticides or the like.
• the tines are designed in such a way that the dispensing ability of the side surfaces of the tines is largely restricted, so that only a relatively small amount of treatment liquid is dispensed.
• ERS ⁇ TZBL ⁇ fT be prongs.
• this comb preferably releases treatment agents to the skin and, moreover, a continuous flow of a larger amount of treatment agents from the reservoir into the prongs is not ensured.
• porous materials for storage and comb combs are preferably provided with a non-oriented fiber orientation and the path of the treatment liquid is unfavorable if the comb handle is also used as a storage for the treatment liquid.
• the object of the invention is to provide a solution which ensures a reliable and uniform dispensing of liquid hair dye and the like in sufficient quantity onto the hair of people without wetting the scalp.
• This object is achieved according to the invention with a device of the type described in the introduction in that the tines are formed with closed pores in the surface region of their free ends, and in that the main pore direction of the second porous material of the tines and the first porous material of the reservoir are essentially rectified is parallel to the longitudinal direction of the tines, the first porous material of the reservoir extending over a multiple of the depth of penetration of the tines in the direction of penetration.
• ⁇ SSA of the hair dye is obtained from the memory into the prongs, so that a uniform amount of hair dye is dispensed at all times, thus resulting in a correspondingly uniform hair dyeing.
• the extension of the first porous material of the reservoir over a multiple of the penetration depth of the tines in the penetration direction enables a sufficiently large amount of hair dye to be stored, the hair dye being due to the short and straight transport path from the first porous Material of the reservoir can flow continuously into the tines without the risk of clogging or drying out. Also, only a small remaining amount of treatment liquid remains unused in the storage.
• first porous material of the reservoir and the second porous material of the tines are formed by compression from non-oriented, fibrous material, the compression of the second porous material being stronger than that of the first material. Due to the compression of the originally non-oriented fibrous material, a largely parallel structure of the main fibers is formed, so that a main pore direction arises. Due to the different compression of the porous material of the reservoir and the tines, pores of different sizes are formed in such a way that a capillary gradient arises from the reservoir into the tines, which increases the flow rate of the hair dye.
• the second porous material of the tines is compressed with heating and gluing.
• a particularly good compression can be achieved by this treatment, as a result of which very small pores form in the tines through which the hair dye flows particularly quickly, so that a continuous discharge flow from the tines to the hair to be colored is established.
• the invention provides that the pores in the surface area of the free ends of the tines are closed by ultrasound, heating or gluing or by fitting a closure means, in particular a closure cap.
• the invention provides that the tines are arranged next to one another on the housing at a distance of approximately 0.5 to 1 mm. This distance between the tines has been found to be particularly favorable because this creates a close contact between the tines and the strands of hair, and thus a particularly good release of the hair dye from the prongs to the strands of hair.
• the tines are arranged on the housing at least in two rows offset from one another.
• the strands of hair are drawn through the tines in a wave-shaped manner during the combing process, so that a particularly good contact is established between the strands of hair and the tines and a particularly good coloring result can thus be achieved.
• the housing is equipped with holders at a distance from the tine roots engaging in the first porous material, the cross section of the holders being slightly different from the round cross section of the tines.
• the slightly different cross-section of the holders and the prongs ensures that air can enter the housing, so that no negative pressure can be created in the housing by dispensing the hair dye.
• the memory has an extension from about 30 to 60 mm in the longitudinal direction of the tines.
• the first porous material of the reservoir and the second porous material of the tines preferably consist of polyester, nylon or acrylic. These materials have proven to be particularly favorable in terms of storage and dispensing ability. With a weight of around 0.07 g, the tines can absorb a quantity of liquid of 0.05 g. Due to this high absorption capacity of the tines, a delivery rate from the tines to the hair of approximately 1.8 g of aqueous solution per minute is possible.
• the invention also provides that the first porous material of the memory is covered by an extruded polyester film. This configuration simplifies production.
• the porous material is continuously produced from very long fibers and compacted by the covering. Appropriate stores can then be separated from the long fibers, adapted to the desired store length.
• the housing is equipped with a removable, airtight closure covering the tines. This prevents the tines from drying out and clogging the pores when the device is not being used for dyeing the hair, which would render the device unusable.
• an insert reducing the interior space of a flexible material with a conical sealing surface for each tine is arranged in the closure, each of which interacts with a corresponding conical sealing surface on the holder.
• This configuration results in a particularly good seal of the tines, so that no evaporation of the hair dye can occur and thus hair dye losses are kept very low.
• a particularly simple design results if a housing part forming the brackets for all tines is arranged between the housing and the closure.
• the invention provides that connecting means for connection to further housings are arranged on the outer surface of the housing.
• connecting means for connection to further housings are arranged on the outer surface of the housing.
• the memory made of the first porous material is exchangeably arranged in the housing. As a result, a device can continue to be used even after the memory has been emptied by inserting a new memory.
• the tines are inserted into one or two stores made of the first porous material from opposite sides. If the tines are only used in a store, stores with a greater longitudinal extent can also be used, which therefore have a greater storage capacity because the transport routes from the store to the tines are then shortened.
• a plurality of stores with tines inserted in them are arranged in a housing next to one another.
• This design is particularly suitable for a housing with a large number of tines arranged next to one another, a particularly large hair surface being dyed during a combing process.
• the usual memories arranged next to one another can then be used.

• FIG. 1 shows an enlarged section of a porous material 1, such as polyester, nylon or acrylic. Fibers 2 of the porous material 1 do not have a preferred orientation, but are branched in all directions. Between see the fibers 2 arranged at a distance from each other, pores 3 are formed which likewise do not have a uniform orientation.
• the starting material 1 is shown after different treatment stages.
• a first porous material 4 (storage 15) and a second porous material 5 (tines 16) have arisen from the starting material 1 by compression of different strengths.
• the first porous material 4 has largely parallel fibers 6, between which correspondingly parallel pores 7 are formed, which have a common main pore direction, which is indicated by an arrow 8 in the drawing.
• the pores 7 are reduced in diameter compared to the pores 3 of the starting material 1, but they are nevertheless large enough to be able to store a sufficiently large amount of hair dye.
• the second porous material 5 is compressed much more than the first porous material 4 by heating and gluing fibers 9. Very narrow pores 10 are formed between the fibers 9 and, like the fibers 9, are oriented in the main pore direction 8.
• the different diameters of the pores 7 of the first porous material 4 and the pores 10 of the second porous material 5 result in a capillary gradient, as a result of which the stored in the first porous material 4 Hair dye accelerates entering the second porous material 5.
• the hair dye then flows through the pores 10 into a pore edge area 12. If the second porous material 5 now comes into contact with strands of hair (not shown in the drawing), the hair dye is delivered to the hair via the pore edge area 12.
• a device 13 has a housing 14 in which a memory 15 made of the first porous material 4 is arranged. Tines 16 made of the second porous material 5 are inserted in the storage 15 next to one another in the area of the tine roots 17 in the storage 15 at a distance of approximately 0.5 to 1.0 mm. The tine roots 17 penetrate approximately 5 mm into the store 15, which has a longitudinal extension of approximately 40 mm.
• the pores 10 of the second porous material 5 of the tines 16 shown in FIG. 2 are closed by ultrasound, heating or gluing, so that no hair dye can escape from the free ends 18 of the tines 16 .
• a housing part 19 is arranged on the housing 14 and has holders 20 for the tines 16.
• the cross sections of these brackets 20 deviate slightly from the circular cross section of the prongs 16, so that when the device 13 is used, air can enter the housing 14 at any time and thus a negative pressure can arise in the housing 14 as a result of the hair dye escaping.
• the tines are rigidly arranged in the housing 14 by the penetration of their tine roots 17 into the storage 15 and the guide in the holders 20, so that they cannot kink or slide out of the housing 14 in the event of a transverse load due to the combing process.
• a closure 21 covering the tines 16 is arranged above the housing 14.
• an insert 22 is formed from a flexible material, which, according to the number of tines 16, has tubular openings 23 which cover the tines 16.
• conical sealing surfaces are in each case Chen 24 arranged, which correspond to corresponding conical sealing surfaces 25 on the brackets 20.
• the hair dyeing process with the device 13 takes place as follows: after the closure 21 has been removed, the teeth 16 are pulled through the head hair in a combing motion so that individual strands of hair reach the area between the teeth 16 . Because of the small distance of the tines 16 from one another, the strands of hair come into contact with the side surfaces of the tines 16, so that 16 hair dye is given to the individual strands of hair via the pore edge region 12 of the second porous material 5 of the tines.
• This dispensed amount is continuously supplied from the storage 15 to the tines 16 at any time by the configuration of the first porous material 4 of the storage 15 and the second porous material 5 of the tines 16 shown in FIGS. In the embodiment shown in FIG. 5, a delivery rate of about 1.8 g of aqueous hair dye per minute can be achieved.
• FIG. 6 shows a further exemplary embodiment, the same reference symbols as in FIGS. 4 and 5 having the additional index "a" being used.
• the device 13a has a housing 14a which is approximately three times as wide as the housing 14 according to FIG. 5.
• three storage units 15a are arranged side by side, the first porous material 4 of which is each covered by a polyester film 26.
• the tines 16a are accordingly inserted next to one another in the stores 15a.
• REPLACEMENT LEAF 7 and 8 show two variants of the invention in a perspective view, the same reference numerals as in FIGS. 4 and 5 being used with the additional index "b" and "c", respectively.
• the tines 16b of the device 13 are arranged in a row next to one another at the same distance.
