Moreover, insertion of the porous comb teeth into the reservoir consisting of another porous material involves considerable assembly work.
3.0 Summary of the Invention:
15Various objects of the present invention are to provide a solution which enables hair treatment preparations of any kind, including those containing small solid constituents, for example multicomponent hair dyes, to be applied much more easily; to provide for making the corresponding applicator in 2a various external shapes to meet all design requirements; and to provide for specifically orienting the path of the capillaries as required.
With the problems of the prior art in mind, one embodiment of the invention includes fabrication of both the teeth and the reservoir in one piece, similar to a comb, from a number of thin plates and/or films arranged in layers one above the other. Slot-like interstices are provided between the 2 ~ ~;
Z~lfi869 . .
individual plates and/or films of such a size that, depending on the particular plate and/or film materials and the hair treatment preparation to be applied, the particular hair ;~
treatment preparation is transported by capillary effect in the ~;
slot-like interstices.
It has been discovered that virtually any materials pro-cessable into plate or film form may be used for a capillary -plate assembly of the present invention, due to the inclusion of surface roughness in the plates or films. Also, the slot-10 like interstices with their potential for capillary action are ~`
formed when the plates or films are placed one on top of the other. For example, the plates or films may be made of ~
virtually any polymers, such as PVC, PE, acrylate, ~ --polypropylene, polycarbonate, and of glass, mica and metals, `~
such as aluminum or stainless steel. The plates preferably .: . .
have a thickness of 0.1 to 0.2 mm(millimeter). However, the thickness of the plates and films may also be in either the ~
1/100 mm range, and/or the ~m(micrometer) range, andJor in the ~ ~-cm(centimeter) range. The slot-like interstices between the .:: :
individual plates or films may vary within relatively wide limits, depending on the surface design of the plates. The slot-like interstices preferably have heights of 5.0 to 150.0 ~m. The surface design is largely determined by the method used to make the plates. For example, longitudinal grooves are formed in standard processes for the production of polyethylene plates. Capillary activity may be influenced or optimized and directed as required by varying the method used to make the plate material, the number of plates, the thickness of the .~ .
~ ~ [)0686~
plates and the surface design (for example grooves, coarseness, curves, profiles, and so forth).
One particularly advantageous embodiment is characterized in that, to form the slot-like interstices, the sur~aces of the plates are profiled in accordance with the desired liquid flow path. For example, grooves radiating from the reservoir part of the plates are extended into the teeth and /or are laterally deflected in uniform distribution over the length of the teeth.
In this manner, the liquid can be fed from the reservoir part of the plate assembly to the gaps between the individual teeth, ar.d the particular hair treatment liquid can also issue laterally from the teeth, for effective transfer to the hair during combing.
The individual plates may be attached to one another at least at two opposite edges, or attached by spot welding. In the latter case, the individual welds are preferably dis-tributed substantially uniformly over the surface of the plates.
The plates of a plate assembly may differ in thickness.
For example, the two outer plates may be thicker than the inner plates for reasons of strength.
In one particularly simple and preferred embodiment, the comb-like plate assembly formed by the plates arranged in layers comprises a lateral handle which forms part of the reservoir. The resulting comb can be optimally adapted by simple means to satisfy all design requirements in regard to shape and also color. For reasons of strength, the two outer ::.
plates may advantageously be made correspondingly thicker. It f 2~6869 has been found that a comb of normal size, particularly by virtue of its lateral handle, already has a considerable storage volume for the particular hair treatment liquid, so that certain hair treatments, for lexample dyeing in streaks, may be carried out without another reservoir. A c~mb of the type in question may of course also continue to be used very easily after emptying, if its teeth are dipped into a separate liquid reservoir. The only requirement in this regard is to ensure that vent openings are associated with the slot-like interstices at the furthest point of the reservoir, i.e. at the free end of the handle, so that when the comb teeth are dipped into the liquid reservoir, the slot-like interstices are completely and quickly refilled by virtue of their capillary conductivity.
The comb-like plate assembly formed by the plates disposed in layers may of course also be arranged, except for its combed teeth, in a housing space designed to be filled with hair treatment preparation. This enables a much larger quantity of hair treatment preparation to be applied by a single applicator. In this case, it does not matter if, during its handling, the plate assembly is not permanently immersed in the hair treatment liquid in the housing space. This can occur shortly before the stored liquid is used up in the upwardly directed position of the comb teeth, because in that case the reservoir formed by the plate assembly arranged in the housing space is able to transfer hair treatment preparation to the hair for a prolonged period, without any need for the residual liquid still present in the housing space to be used. When th6 Z00686~
,.
comb changes position again, into a position in which its teeth are directed downward, the residual liquid is also able to enter the slot-like interstices between the individual plates, and can be transferred to the hair via the teeth. -A part of the housing space surrounding the plate r;`,, assembly may of course also be filled with capillary-conductive porous material in the form of an additional reservoir, thereby guaranteeing a permanent flow of liquid into the slot-like interstices of the plate assembly.
The slot-like interstices at the free ends of the comb teeth may be made closed if, for example, a hair treatment iquid such as hair dye is not to be applied to the scalp of ~uman beings, as is the case with the hitherto known porous comb teeth where all the pores at the free ends of the teeth are closed.

DETAILED DESCRIPTION OF THE INVENTION
In the embodiment shown in Figure 1, a plate assembly 2, shown in detail in Figures 2 and 3, is arranged in a part 3 of a multiple-part housing globally denoted by the reference 1.
As shown in Figures 2 and 3, a number of comb teeth 4 forming the above-mentioned teeth 4 is formed by sawing or the like along the one edge of the plate assembly 2. The distance 5 between the individual comb teeth 4 preferably corresponds to half the width 6 of the comb teeth. The plate assembly 2, including the comb teeth 4, consists of a number of parallel plates 7 with slot-like interstices 8 between the individual plates 7. The interstices 8 form capillaries for the capillary transport of a hair treatment preparation. The plates 7 are attached to one another at least at two opposite edges, for example by bonding, welding, laser treatment or the like (this feature of the applicator is not shown in detail). The free ends of the comb teeth 4 may be made closed, as described above. In this manner, when the comb teeth 4 are drawn through Z0~686~
the head hair of a human being, a hair treatment liquid stored in the slot-like interstices 8 of the plate assembly 2 i5 transferred to the hair without directly wetting the scalp, as is generally desired for example in the application of hair dyes.
Depending on the plate materials used and their surface design, the slot-like interstices 8 may vary considerably in regard to their distance from one another, which accounts for the above~mentioned size of these interstices of from S.O to 150.0 ~m. Outside the region of the teeth 4, the slot-like interstices 8 form the reservoir for the hair treatment preparation.
The constituent material of the plates 7 may be optimally adapted to the particular application envisaged, for which purpose a number of materials may be used, as previously .-mentioned. The thickness of the plates 7 may also be varied ~;`
according to the particular application, and is preferably between 0.1 and 0.2 mm, as previously mentioned.
An insert 10 is arranged in a closure cap 9, and co~
20 operates through conical sealing surfaces 11 with corre-~ ~
sponding conical sealing surfaces 12 on the housing part 3, ;-hermetically sealing off the comb teeth 4. The latter project beyond the housing part 3 when the closure cap 9 is removed, from their surroundings, so that no hair treatment preparation -~ -25 is able to issue from the slot-like interstices 8 of the comb ~ -teeth 4. Also, these slot-like interstices 8 of comb teeth 4 : ~:
cannot become blocked by drying out. - -Accommodatecl in the housing 1 is a liquid hair treatment ~ ;
8 -~
--` Z00~i8~
preparation 14, which is used to replenish the volume of liquid stored in the slot-like interstices 8 of the plate assembly 2, and can enter the slot-like interstices 8 through their lateral openings. As can be seen, this guarantees complete release of the hair treatment liquid 14 if, after removal of the closure cap 9, the applicator 1 is turned through 180~ and is drawn in this position through the hair oi` a human being or animal.
With applicator 1 in this position, the residual liquid 14 collecting in the housing part 3 can still laterally enter the slot-like interstices 8 of the plate assembly 2. However, even in cases where the applicator 1 is handled in the position shown in Figure 1, for example during the treatment of long-haired dogs with a liquid insecticide or the like, the release of liquid in the region of the comb teeth 4 is always guaranteed because the entire volume of liquid in the plate assembly 2 serves as a liquid reservoir. It is only after this liquid reservoir formed by the plate assembly 2, itself has been completely emptied that the applicator 1 need be briefly turned only once through 180~ to allow the residual liquid still present in the housing to enter the slot-like interstices 8 of the plate assembly 2, and then to be applied to the hair of human beings or animals by turning the applicator back through 180~ into the position shown in Figure 1.
The embodiment shown in Figure 4 corresponds in every respect to the embodiment shown in Figures 1 to 3, except for the inclusion of an additional reservoir 15 of capillary~
active, preferably fibrous, material arranged inside the housing la. In this embodiment, the plate assembly 2a pushed 9 ~ ~, '' "~'''''',.`.' ,. .

--`` Z~10~13fi9 into the reservoir 15, or rather its individual plates 7, preferably terminate(s) in the shape of a saddle roof at the end 16 entering the reservoir 15, so that the transfer of liquid from the additional reservoir 15 to the slot-like inter-S stices 8 of the plate assembly 2a is further improved.
In the e~bodiment shown in Figure 5, a co~b globally denoted by the reference 17, with a handle 18 and comb teeth 19, is formed by cutting out from a plate assembly 2 in basically the same way as in the case of the plate assembly 2 shown in Figures 1 to 3. The region of the handle 18 serves as an additional reservoir from which hair treatment liquid is able to flow through the region 20 immediately associated with the comb teeth l9, providing the comb teeth l9 are drawn through the hair in the manner previously described, and providing it is guaranteed that openings 21 (not shown in detail) are provided at the free end of the handle 18, in the region of the gap-like interstices 8 between the plates 7 forming the comb 17. The remaining peripheral regions of the handle 18 may be made closed to prevent the hand holding the handle 12 from being wetted with stored hair treatment preparation. A comb 17 of this type may either be used very simply as a non-reusable comb, for example if only a small volume of hair treatment liquid is required, as is the case for ., the production of dyed strands of hair, for example for punk or 25 carnival stylesO However, relatively large quantities of hair :~
treatment liquid may also be applied to the hair with a comb 17 -of the type in question, by immersion of the comb teeth 19 in a ~-corresponding liquid reservoir after emptying of the comb 17.

In this manner, all slot-like interstices 8 between the individual plates 7 forming the comb 19 are quickly and completely refilled, so that more hair treatment liquid 14 may be applied.
Numerous modifications to the described embodiments, and many other embodiments of the invention based on the principles described above, are possible without departing from the spirit and scope of the invention as clain~ed in the appended claims.

This enables a much larger quantity of hair treatment preparation to be applied by a single applicator. In this case, it does not matter if, during its handling, the plate assembly is not permanently immersed in the hair treatment liquid in the housing space. This can occur shortly before the stored liquid is used up in the upwardly directed position of the comb teeth, because in that case the reservoir formed by the plate assembly arranged in the housing space is able to transfer hair treatment preparation to the hair for a prolonged period, without any need for the residual liquid still present in the housing space to be used. When th6 Z00686~
,.
comb changes position again, into a position in which its teeth are directed downward, the residual liquid is also able to enter the slot-like interstices between the individual plates, and can be transferred to the hair via the teeth. -A part of the housing space surrounding the plate r;`,, assembly may of course also be filled with capillary-conductive porous material in the form of an additional reservoir, thereby guaranteeing a permanent flow of liquid into the slot-like interstices of the plate assembly.
The slot-like interstices at the free ends of the comb teeth may be made closed if, for example, a hair treatment iquid such as hair dye is not to be applied to the scalp of ~uman beings, as is the case with the hitherto known porous comb teeth where all the pores at the free ends of the teeth are closed.

DETAILED DESCRIPTION OF THE INVENTION
In the embodiment shown in Figure 1, a plate assembly 2, shown in detail in Figures 2 and 3, is arranged in a part 3 of a multiple-part housing globally denoted by the reference 1.
As shown in Figures 2 and 3, a number of comb teeth 4 forming the above-mentioned teeth 4 is formed by sawing or the like along the one edge of the plate assembly 2. The distance 5 between the individual comb teeth 4 preferably corresponds to half the width 6 of the comb teeth. The plate assembly 2, including the comb teeth 4, consists of a number of parallel plates 7 with slot-like interstices 8 between the individual plates 7. The interstices 8 form capillaries for the capillary transport of a hair treatment preparation. The plates 7 are attached to one another at least at two opposite edges, for example by bonding, welding, laser treatment or the like (this feature of the applicator is not shown in detail). The free ends of the comb teeth 4 may be made closed, as described above. In this manner, when the comb teeth 4 are drawn through Z0~686~
the head hair of a human being, a hair treatment liquid stored in the slot-like interstices 8 of the plate assembly 2 i5 transferred to the hair without directly wetting the scalp, as is generally desired for example in the application of hair dyes.
Depending on the plate materials used and their surface design, the slot-like interstices 8 may vary considerably in regard to their distance from one another, which accounts for the above~mentioned size of these interstices of from S.O to 150.0 ~m. Outside the region of the teeth 4, the slot-like interstices 8 form the reservoir for the hair treatment preparation.
The constituent material of the plates 7 may be optimally adapted to the particular application envisaged, for which purpose a number of materials may be used, as previously .-mentioned. The thickness of the plates 7 may also be varied ~;`
according to the particular application, and is preferably between 0.1 and 0.2 mm, as previously mentioned.
An insert 10 is arranged in a closure cap 9, and co~
20 operates through conical sealing surfaces 11 with corre-~ ~
sponding conical sealing surfaces 12 on the housing part 3, ;-hermetically sealing off the comb teeth 4. The latter project beyond the housing part 3 when the closure cap 9 is removed, from their surroundings, so that no hair treatment preparation -~ -25 is able to issue from the slot-like interstices 8 of the comb ~ -teeth 4. Also, these slot-like interstices 8 of comb teeth 4 : ~:
cannot become blocked by drying out. - -Accommodatecl in the housing 1 is a liquid hair treatment ~ ;
8 -~
--` Z00~i8~
preparation 14, which is used to replenish the volume of liquid stored in the slot-like interstices 8 of the plate assembly 2, and can enter the slot-like interstices 8 through their lateral openings. As can be seen, this guarantees complete release of the hair treatment liquid 14 if, after removal of the closure cap 9, the applicator 1 is turned through 180~ and is drawn in this position through the hair oi` a human being or animal.
With applicator 1 in this position, the residual liquid 14 collecting in the housing part 3 can still laterally enter the slot-like interstices 8 of the plate assembly 2. However, even in cases where the applicator 1 is handled in the position shown in Figure 1, for example during the treatment of long-haired dogs with a liquid insecticide or the like, the release of liquid in the region of the comb teeth 4 is always guaranteed because the entire volume of liquid in the plate assembly 2 serves as a liquid reservoir. It is only after this liquid reservoir formed by the plate assembly 2, itself has been completely emptied that the applicator 1 need be briefly turned only once through 180~ to allow the residual liquid still present in the housing to enter the slot-like interstices 8 of the plate assembly 2, and then to be applied to the hair of human beings or animals by turning the applicator back through 180~ into the position shown in Figure 1.
The embodiment shown in Figure 4 corresponds in every respect to the embodiment shown in Figures 1 to 3, except for the inclusion of an additional reservoir 15 of capillary~
active, preferably fibrous, material arranged inside the housing la. In this embodiment, the plate assembly 2a pushed 9 ~ ~, '' "~'''''',.`.' ,. .

--`` Z~10~13fi9 into the reservoir 15, or rather its individual plates 7, preferably terminate(s) in the shape of a saddle roof at the end 16 entering the reservoir 15, so that the transfer of liquid from the additional reservoir 15 to the slot-like inter-S stices 8 of the plate assembly 2a is further improved.
In the e~bodiment shown in Figure 5, a co~b globally denoted by the reference 17, with a handle 18 and comb teeth 19, is formed by cutting out from a plate assembly 2 in basically the same way as in the case of the plate assembly 2 shown in Figures 1 to 3. The region of the handle 18 serves as an additional reservoir from which hair treatment liquid is able to flow through the region 20 immediately associated with the comb teeth l9, providing the comb teeth l9 are drawn through the hair in the manner previously described, and providing it is guaranteed that openings 21 (not shown in detail) are provided at the free end of the handle 18, in the region of the gap-like interstices 8 between the plates 7 forming the comb 17. The remaining peripheral regions of the handle 18 may be made closed to prevent the hand holding the handle 12 from being wetted with stored hair treatment preparation. A comb 17 of this type may either be used very simply as a non-reusable comb, for example if only a small volume of hair treatment liquid is required, as is the case for ., the production of dyed strands of hair, for example for punk or 25 carnival stylesO However, relatively large quantities of hair :~
treatment liquid may also be applied to the hair with a comb 17 -of the type in question, by immersion of the comb teeth 19 in a ~-corresponding liquid reservoir after emptying of the comb 17.

In this manner, all slot-like interstices 8 between the individual plates 7 forming the comb 19 are quickly and completely refilled, so that more hair treatment liquid 14 may be applied.
Numerous modifications to the described embodiments, and many other embodiments of the invention based on the principles described above, are possible without departing from the spirit and scope of the invention as clain~ed in the appended claims.
