DESCRIPTION

Device, kit and method for coloring the hair Field and background of the invention

The embodiments of the present invention relate to a hair coloring applicator device and a related method for hair coloring.

Particular embodiments may be useful for the temporary coloring of gray hair, for example in or near the hair roots.

Hair dyes are commonly used to hide gray and white hair typically caused by aging, as well as to alter other hair colors to suit personal taste. Hair dyes can be broadly classified into several types, although dyes of different types can be combined and some dyes may not only belong to some type [Anderson, J. Soc. Dyers Colourists, 116: 193-196 (2000); Zviak and Millequant, [Zviak, Charles; Millequant, Jean. Editor (s): Bouillon, Claude; Wilkinson, John. Science of Hair Care (2nd Edition) (2005), 251-275. Publisher: CRC Press LLC, Boca Raton, Florida].

Permanent dyes are usually formed by mixing small aromatic precursors with an oxidizing agent, typically hydrogen peroxide. Following oxidation, the precursors react covalently with each other to form a dye. Small precursor molecules can diffuse to the hair more effectively than the larger dye molecule can diffuse outward. An alkalizing agent, typically ammonia, is also added in order to cause swelling of the hair, which allows maximum penetration of the precursors to the hair. In addition, peroxide bleaches the color of the original hair, thereby allowing the color of the dye to replace the color of the original hair. Permanent dyes are quite popular, but suffer from the deficiency of the complexity of correctly mixing and applying precursors and the use of potentially dangerous reagents. Thus, permanent dyes are normally applied by professional hair stylists. In addition, even permanent coloration cannot hide the original hair color that inevitably reappears with new hair growth.

Semi-permanent dyes are similar to permanent dyes, but use lower concentrations of peroxide and an alkalizing agent that is less effective than ammonia, but have a less unpleasant smell. Semi-permanent dyes are therefore less effective in penetrating the hair and bleaching the original hair color and cannot be used to effectively color predominantly gray or white hair. However, the relative softness of such dyes makes them desirable when a less effective coloration is sufficient, such as when gray or white hair constitutes the minona of the hair.

Semi-permanent dyes typically comprise molecules, such as nitrophenylenediamines and nitroaminophenols, which are small enough to diffuse to the hair. Such dyes do not require additional reagents and are therefore easy to use, but are less effective than permanent dyes, fade relatively quickly after several shampooing applications and cannot bleach the original hair color.

Temporary dyes typically do not penetrate hair and are therefore suitable for only moderate changes in hair color. They are also removed by the first application of shampoo and are therefore appropriate for individual occasions to make slight alterations to hair color, such as hiding gray or new white growth until a more permanent dye is applied. Because temporary dyes do not need to comprise small molecules capable of penetrating hair, a wide variety of compounds can be used, which facilitates convenience. For example, you can select dyes that have no risk of inducing an allergic reaction, which is not possible with more permanent dyes. There are also a large number of shadows to choose from.

The ideal features of a temporary hair dye depend on the exact use of the dye. Typically, however, it is important that the dye be easily removable by shampoo but not by rain, perspiration or friction of clothing or pillowcases. It is also desirable that the dye has a sufficiently high affinity to the hair and that it also colors the hair.

Temporary hair dyes have been used as ingredients in shampoos and conditioners, shading enhancers, colored hair sprays and masks, aimed at being applied to the entire head of the hair or as wicks. To provide an equal and stable coloration there are often several families of dyes used in a formula. The charge of the dyes can be negative or positive to provide high or low affinity to the hair shaft, since positively charged dyes (basic dyes) have a higher affinity to the hair.

Common temporary hair dyes include azo derivatives, basic triphenylmethane dyes such as methyl violet, azine derivatives such as safranine and indoamines and indophenols [Zvlak and Millequant,

supra (2005)]. Colored polymers have been used, also as artificial melanin.

Polymeric dyes with a strong affinity to hair are often semi-permanent or permanent dyes. Examples of polymers with strong affinity to hair that are semi-permanent dyes are disclosed in US Patents 4,182,612 and 5,827,330.

A polymeric temporary dye after this should have a maximum moderate affinity to the hair and more desirable a low affinity to the hair. Examples of polymers suitable for temporary hair coloring are disclosed for example in US Patents 5,737,907 and 5,891,199.

Tanic acid or gallic acid produced by hydrolysis of tanic acid has been combined for centuries by ferrous ions to produce ferro gallic ink. After writing with the pale ink, the ferrous ions are oxidized by atmospheric oxygen to ferric ions, which react with the tanic acid to produce a dark violet-black organo metallic polymer that can be permanently bound to protections such as those in parchment. Ferro Galica ink is rarely used today, because the paper does not include protemes and excess iron atoms are highly corrosive, damaging both the paper and the pens.

A similar process has been used to permanently or semi-permanently have hair with a dye that binds to the hair's protection. For example, EP Patent No. 327,345 discloses a kit comprising a shampoo comprising ferrous ion for washing the hair and a solution comprising tanic acid that is applied to the hair after the shampoo in order to create a semi-permanent black dye. Such a kit is inappropriate for use as a temporary dye because the dye is semi-permanent and because the use of two solutions (a tanic acid solution and a ferrous ion solution) is too long and complex to be pleasing to consumers. In addition, the kit disclosed in it must be used more than once in order to obtain full coloration.

Japanese Patent No. 2,014,324 and US Patent No. 4,946,472 disclose hair dyes comprising ferric ion and tanic acid in a single formulation. The dyes used in the inked formulations, however, are not temporary.

Chinese Patent Application No. 1990-104,017, Japanese Patents No. 3,014,160 and 48,031,902 and Japanese Patent Application No. 2002-47,287, 1993-312,065, 1988-292,113 and 1984-65,068 disclose permanent or semi-permanent hair dyes comprising Ferrous ion and tanic acid in a single formulation. Based on the art of tanic acid-iron dyes, it is believed that the ferrous ion undergoes oxidation to ferric ion (for example, by exposure to air) before reacting with tanic acid to produce a colored polymeric iron tanate. Oxidation of ferrous ions in a hair dye that has been applied to the hair results in the formation of an iron tanate polymer bonded strongly to the hair, making the dye non-temporary. These patents and patent applications say nothing regarding compositions comprising tanic acid and ferric iron ions, leaving compositions that are devoid of unbound ferric ions.

Japanese Patents Nos. 61,055,483, 130,823, 94,800 and 93,052 and Japanese Patent Application Nos. 2005206,160, 2000-85,556, 1990-336,606, 1987-245,287, 1984-177,514 t 1972-81,137 disclose permanent or semi-permanent hair dyes comprising two formulations, one of which comprises iron ions and the other comprising tanic acid. The mixture of the two solutions in the hair allows the production of iron tanate in the hair, the iron tanatos by this are linked to the hair.

In addition to the inability of such formulations to serve as temporary dyes, tanic acid-iron hair dyes suffer from several general deficiencies. The dark black color is not pleasant to many consumers. In addition, all the formulations mentioned above comprise unbound iron ions. Unbound iron is corrosive and the ferrous ion in particular produces highly oxidizing free radicals through the Fenton reaction. Excess iron can damage hair and cause hyperpigmentation of unpleasant skin [Landsown, Int. J. Cosmetic Sci., 23: 129-137 (2001)].

Melanoidins are the family of brown compounds that result from the interaction between sugars and amino acids under moderate heat. Melanoidins are responsible for much of the tanning and taste of cooked foods and here they are recognized as highly safe agents. However, melanoidins have not been disclosed as hair dyes so far.

It is advantageous that temporary hair dyes comprise an appropriate formulation to apply the colored compound (s) included therein to the hair with the desired ease and convenience. For example, the formulation may include solvents and / or agents with surface activity that allow solubilization of the colored compound and are still the quick dry formulation. It is also desirable in many cases that the formulation includes ingredients that prevent temporary hair coloring from fading and / or rubbing prematurely.

PCT Patent Application No. WO 94/10968 teaches an aqueous hair dye composition comprising solubilized melanin and a cationic material that binds to solubilized melanin to the hair through

of electrostatic interactions. Melanin is preferably solubilized upon being oxidized with hydrogen peroxide, which is taught herein that imparts an ionic character to melanin. The cationic material, such as a quaternary or polyquaternary compound, is taught herein that complexes anionic melanin in a manner that increases the affinity of melanin to the hair.

US Patent No. 6,506,374 teaches a hair coloring composition comprising alcohols to allow rapid drying and a polymer that prevents color from coming off.

US Patent No. 5,821,240 teaches an aqueous hair coloring composition that includes a functional quaternary ammonium silane to prevent detachment.

Japanese Patent Application No. 1993-312,065 teaches a hair coloring composition comprising tanic acid, ferrous salts and a silicone oil, such as a silicone-polyether ether copolymer. Such silicone oils are agents with non-volatile surface activity useful in the formation of soft film on hair.

Since temporary hair dyes are desired for the ease and potential convenience of their use, it is particularly advantageous to have a rapid and convenient technique for applying such dyes. Colored dyes in the form of pencils or wick type applicators (for example, US Patent No. 5,964,222) are frequently used to touch the hair along the hairline. Another technique involves combining the hair with a temporary hair coloring gel. In an additional technique, hair coloring powder is applied by squeezing a bottle or by an aerosol container to fill the powder that is then worked on the hair line with the fingers.

Another device for coloring the hair is known from WO2009 / 078017 Summary of embodiments

The invention is defined by the features of the appended claims.

The present disclosure describes a hair coloring applicator device comprising (i) a shielding device that includes an upper surface and a lower surface and (ii) an aerosol assembly for administering a hair coloring composition or coloring agent for hair on the upper surface of the shield.

At any given time, the hair coloring applicator device may be useful for coloring the hair in a specific "local treatment region" - for example in or near the hairline that delineates the border between the user's forehead and a higher "mass of hair" on the user's head. For example, instead of using the device to color all or the mayonnaise of your hair, the device is especially useful for "touching" the hair branches of visible regions of hair where the hair is.

In a usage scenario, the user colors or tinses the mayona of his hair from a "natural color" to a "target hair color" using any technique known in the art. At a later time (for example, a few days or a few weeks later), the user's hair has grown in such a way that the branches of his hair are reverted to the "natural" color. In many of these use cases, instead of rectifying this situation by coloring the entire mass of hair (or even a significant fraction), the user is primarily interested in "touching" shamefully visible regions (for example, near the line of the hair that borders the forehead) where the hair branches have reverted to their natural color. According to this other use scenario, the user may be interested in a "low effort" solution where local hair regions are treated quickly without requiring significant effort on the part of the user.

In some embodiments, the shielding portion of the presently disclosed hair coloring applicator may include a plurality of narrow elongated grooves (eg, substantially parallel to each other), through which strands of hair can pass. During use, (i) the hair coloring composition is sprayed from the spray assembly to a region of space "above" the hair shield; (ii) the shield is oriented to be substantially parallel to the local plane of the user's hair leather, such that the user's hair leather in the "treatment region" is under the shield and protected by the coloration shield of the composition for the hair that the leather can have, hair and (iii) the user's hair in the "treatment region" travels (that is, in an "upward" direction) the thickness of the shield through the elongated grooves, such so that at least a portion (including, hair branches) of hair strands is located "above" the shield (in contrast to the scalp that is "under the shield" and protected from the hair composition).

When the user atomizes the hair coloring composition in a region of space "above" the shield, the hair coloring composition makes contact with the "through" hair strands to color at least a portion of the strands of hair (for example, by coating the hair), preferably for coloring the roots of the hair strands. Also, because the elongated grooves are generally "narrow" (although wide enough to accommodate the hair strands through), the shield

it can substantially prevent the composition of hair color that can be "deposited" on the upper surface of the shield from advancing (that is to move in a "down" direction) under the shield to make contact with the scalp itself. Such contact can in many use scenarios be harmful - for example, it can have the scalp.

As indicated above, in many usage scenarios, the user only wishes to color the antiseptic hair roots (or other undesirable color) in specific localized regions. In this scenario, the user may in general be interested in a "quick and easy low effort solution" that does not require much effort to spend any significant effort.

In some embodiments, instead of coloring the hair with a hair coloring cream or gel or a foam as is known in the art (typically, the user will need to spend effort manually working on or "combining" cream, gel or foam), It may be advantageous to employ a quick-drying and / or non-viscous coloring composition that is configured to coat hair strands without causing the hair strands to stick together and without any need to "manually work" the hair coloring composition at hair.

While a "quick-drying" and / or "non-viscous" hair coloring composition can be easy to work (that is, there is no "work the hair" coating and / or generally dries quickly), A Outstanding feature of non-viscous liquids is that they tend to run or flow, which could increase the likelihood of exposure of the scalp to the hair coloring agent. For example, the hair coloring composition may be fed on the upper surface of the shield as a mist or even as a fine mist.

In some embodiments, it can be challenging to protect the hair leather under the shield from the hair coloring mist drops (for example, accelerated by the administration of the spray assembly) and / or a hair coloring agent provided as a non-viscous liquid.

Embodiments of the present invention are concerned with methods and apparatus that (allow the hair to penetrate upward above the shield, such that the roots can be colored by the coloring composition for the fed hair (such as an atomization) on the upper surface of the shield; however, they protect the scalp under the shield of even non-viscous hair coloring agents and / or hair coloring agents fed as a stream of droplets.

Experiments carried out by the present inventor have indicated that one or more of the following geometric properties may be useful for shielding:

(A) The elongated grooves described are wide enough to accommodate the strands of hair that extend upward but narrow enough such that substantial amounts of hair coloring composition do not penetrate down the shield on the scalp;

(B) the narrow elongated grooves can have some kind of length element - that is, they can be long enough to allow "significant amounts" of hair to travel up the grooves above the shield where the hair composition It is fed from the spray assembly. Elongated but narrow grooves thus have some kind of "groove aspect ratio" elevated in relation to the groove length (the rest is either the entire length of the groove or the "aspect ratio" within a groove section which has some kind of length) with some measure of the groove width - in some embodiments, the "groove aspect ratio" can be at least 30 or at least 40 or at least 60 or at least 70 or by at least 80 or at least 90 or at least 100);

(C) the shielding portion of the device may include a plurality of generally aligned and / or substantially parallel teeth that are "closely spaced" from each other - for example, grooves or spades between laterally neighboring teeth may have any "narrow groove" property. "Or" narrow space "to block the hair coloring composition from penetrating the" scalp shield "down;

(D) Although the teeth are not "extremely narrow" in some embodiments, the teeth are not "too wide" (for example, teeth that are too wide can reduce the number of grooves that can be adjusted in a device that is not "too much"). width"). In some embodiments, the upper limit (for example, averaged over a significant mayona or mayona or very significant mayona of the teeth and / or averaged over the entire length of the teeth averaged over some longitudinal section of the teeth or shield) for width of teeth (or the upper limit for average distances between slots) can be 4 mm to 3 mm or 2.5 mm or 2 mm). Because the "longer tooth" can provide a more efficient device (that is, longer grooves to accommodate more strands of hair) means that the teeth may have some kind of tightness property, in some embodiments, the "proportion of tooth aspect ”can be relatively large, for example at least 20 or at least 30 or at least 40 or at least 50 or any range or value disclosed therein. The tooth aspect ratio discussed hereinafter, is relative to the tooth length to tooth width or thickness or cross section averaged over the entire tooth or some "tooth section / tooth length" along the axis of the tooth).

(E) The shape of the cross section of the tooth (or the cross section of the ford between laterally neighboring teeth) can also play a role in the shielding of the hair leather under the shielding while facilitating the upward travel of hair strands, of such that the hair roots are "exposed" to the spray-colored hair coloring composition. Thus, in one example, the present inventors have discovered that teeth of substantially triangular shape pointing upwards (that is, teeth having a substantially triangular-see cross section, for example Figures 15, 21-22) can provide excellent results. These teeth, that is, the cross section of the tooth in a significant mayona or mayona or very significant mayona of sites along the axis of the tooth) can be configured such that the narrowest "space" between laterally neighboring teeth is close of the bottom of the tooth. Not wishing to be limited by the teona, it will be noted that by locating the “narrowest space” between teeth near the bottom of the tooth, this may facilitate a situation where the root (and not just a “higher” section of a strand of hair ) upwards penetrates over the “closest space” between teeth to a region that is more exposed to the feeding of the spray hair coloring composition. Also, because the teeth are narrower near the top, the ford between teeth is wider at "higher" sites near the top of the ford or the upper part of the laterally neighboring teeth. This hollow symmetry provided by the tooth geometry means that the roots of the hair bristles at sites above the "narrowest space between teeth" are less likely to be protected by the teeth at this "higher" site above the " narrower space between teeth ”;

(F) it is disclosed that there is no requirement that triangular tooth cross sections and in some embodiments, one or more elements associated with triangular shaped tooth cross sections for any form of cross section of the tooth. Thus, in some embodiments, the cross section of the tooth and / or the ford between laterally neighboring teeth may have an asymmetric width profile, such that the tooth is wider at the bottom (that is, on average, in the mayona of the sites) and narrower at the top (or vice versa, so that the ford is wider at the top and narrower at the bottom, so that the “narrowest space” is located near the phone of neighboring teeth).

(G) in some embodiments, the topography of the upper surface of the shield and lower surface of the shield may be different, such that the upper part of the shield feels relatively rough or rough (for example, due to an undulating undulating surface the lateral section) and the bottom of the shield feel relatively smooth (the "length scale" for roughness or roughness and smoothness would typically be about 1 mm (that is, 0.5 mm or 0.75 mm or 1.25 mm or 1.5 mm or 2 mm).

This can be observed by observing the trajectory of a cylinder whose radius is 0.5 mm or 0.75 mm or 1 mm or 1.25 mm or 1.5 mm or 2 mm and whose length is at least 0.5 cm or at least 1 cm or by at least 2 cm or at least 3 cm or at least 4 cm) on the top and bottom surfaces. The upper surface that is "rough" will cause the cylinder to undulate or oscillate when it is moved in a lateral direction on the upper surface of the shield to a larger or much larger magnitude than when in an identical experiment the same cylinder is moved in a lateral direction on the bottom surface of the shield (where the vertical oscillations or undulations may be non-existent or much smaller).

In one example, for a majority of teeth between teeth of an arrangement of teeth (of any number disclosed herein), when the cylinder is "rolled" or moved laterally on the upper surface of the shield in the lateral direction, the wavy cylinder or it will oscillate at a first magnitude where the magnitude of the vertical oscillations or undulations would be at least 0.5 mm or at least 1 mm or measured that is equal to the radius or 1.5 times the radius of the cylinder. When the same cylinder, in the same place, is moved on the lower surface of the shield, the magnitude of vertical oscillations or undulations for the lower surface (that is, a second magnitude) becomes smaller (that is, having a value is a at least 50%, or at least 30% or at most 20% or at most 10% of the first observable magnitude for the upper surface - for example, Figure 25A appears to Figure 27).

In some embodiments, the ratio of (i) the magnitude of the vertical undulations / oscillations for the upper surface (that is, measured by the given cylinder) to (ii) the magnitude of the vertical undulations / oscillations for the upper surface (this it is, measured for the same given cylinder) can be at least 1.5 or at least 2 or at least 3 or at least 5.

In one example, for the upper surface, the magnitude of oscillations or undulations of the cylinder can coincide (that is, within a tolerance of 60%, 50% or 30%) of the radius of the cylinder.

As used herein, "around" refers to ± 10%.

The term "comprising" means that other steps and ingredients that do not affect the final result can be added. This term covers the terms "consisting" and "consisting essentially of".

As used herein, the singular form "one", "a" and "the" include plural references, unless the context clearly determines otherwise. For example, the term "a compound" or "at least one compound" may include a plurality of compounds, including mixtures thereof.

Some embodiments of the present invention are concerning methods and apparatus that were disclosed in PCT / IL2008 / 001630 which (i) was presented on December 17, 2008; (ii) was published on June 25, 2009 as WO / 2009/078017 and (iii) is incorporated herein by reference in its entirety. In some embodiments, any element or combination of elements described herein may be combined with any element or combination of elements described in Application PCT / IL2008 / 001630.

The present invention, in some embodiments thereof, is of a hair coloring applicator and hair coloring agents and compositions that can be used to color the hair.

Specifically, the present invention can be used to color ("touch up") the hair along a hairline in a quick and convenient manner, particularly with a temporary hair coloring composition that is based on coloring agents. of hair that are substantially natural (for example, derived from substances that occur in nature), environmentally compatible and that exhibit natural hair shadows and / or an appropriate volatile carrier devoid of alcohol.

The principles and operation of a hair coloring applicator according to the present invention can be better understood with reference to the attached figures and descriptions.

Before explaining at least one embodiment of the invention in detail, it will be understood that the invention is not limited in its application to construction details and the arrangement of components summarized in the following description or illustrated in the figures. The invention is suitable for other embodiments or to be carried out in various ways. Also, it will be understood that the expression and terminology used herein is for the purpose of description and should not be considered as limiting.

Figures 1-4 illustrate several views of an apparatus for coloring the hair according to some embodiments. Figures 5-6 illustrate an arrangement of teeth.

Figures 7-8 illustrate a side view of an apparatus for coloring the hair according to some embodiments.

Figures 9-10 illustrate a detailed view of an apparatus for coloring the hair according to some embodiments.

Figures 11A-11C illustrate a usage scenario where a user uses a hair coloring device 200 to color their hair roots - for example in the "peripheral" region 490 that borders the forehead. Figure 12 illustrates another use case. Figures 13A-13C are side views of the device 200 used in the use cases of Figures 11A-12. As will be discussed later here, in a non-limiting use scenario, the device 200 that includes the shield 220 may be useful for coloring the user's hair (more specifically the user's hair roots) as an aerosol spray (by for example, a mist or a stream of drops that include a hair coloring agent and an alcoholic solvent), while simultaneously protecting the wearer's scalp from being subjected to the hair coloring agent.

In some embodiments, the hair color provided in the form of an atomization is "fast drying" and / or non-viscous. In these embodiments, despite the ability of the hair coloring solution to "run" after being deposited on the surface of the shield 220 (that is, due to the non-viscous nature of the hair coloring composition in these embodiments ), the shield 220 can nevertheless provide geometric properties that facilitate the protection of the user's scalp from the hair coloring agent. As will be discussed later here, in order to provide this protection and / or other features, the shield 220 may in some embodiments provide one or more of the following features: (i) "elongated thin" grooves having a high " groove effect ratio ”; (ii) an arrangement of narrowly spaced teeth where the teeth or the fords between the teeth have a "high aspect ratio"; (iii) teeth with a specific cross-sectional shape (for example, triangular) and / or one or more additional elements discussed herein.

The device 200 comprises: (i) a relatively flat hair penetration shield 220 and (ii) an aerosol assembly 400. The hair coloring spray atomization is stocked with the aerosol opening / exit 210 on the surface 280 "Front" of shield 220 - the path taken by the aerosol on top / front surface 280 is illustrated by the block arrow marked "atomization" in Figures 13A-13C and is also marked as element 430 in Figure 11B

While it is not a limitation, in some embodiments, the atomization is a "fan atomization" configured to angularly distribute the aerosol atomization substantially uniformly over an angle that is at least 20 degrees or at least 30 degrees or at least 40 degrees and / or at least 180 degrees and / or at most 120 degrees and / or at most 90 degrees and at most 70 degrees and / or at most 50 degrees and / or at most 40 degrees. In some embodiments, the fan atomization produced by the aerosol assembly has a substantially flat shape (that is, in a plane that is substantially parallel to the relatively flat shield surface 220 and / or intersects with this surface at an angle of less than 30 degrees or less than 20 degrees or

less than 10 degrees). A discussion about the association set that includes the hole and the "atomization insert" is subsequently provided herein with reference to Figure 30A-B.

In some embodiments, (i) this spray atomization is directed to the front surface 280 of the shield 220 and (ii) the mechanical structure of the shield 220 blocks this spray from reaching space 450 under the shield 220-that is, space on the side of shield 220 defined by inner / back surface 290 of shield 220. In the example of Figures 11A-12, shield 220 may be oriented such that the back surface 290 is held against the scalp of the wearer "Below" the rear surface 290-see Figures 11A-12 where the front surface 280 is "facing away from the user's scalp", while the rear surface 290 (not visible in Figures 11A-12) It is pressed against the user's scalp. In this example, the shield 220 is oriented to the relatively flat structure of the shield 220 is pressed against and substantially parallel to the "relatively flat local surface" of the user's scalp.

For the present disclosure, the terms "above" and "below" of shield 220 refer to "above" and "below" of shield 220 along the "shield thickness axis" 270 defined in Figures 13A-13C regardless of the orientation of the shield 220 or the device 200. In Figures 13B-13C, the region "above" the shield 220 is marked as 702, while the region "below" the shield 720 is marked as 704. Due to which the term "above" and "below" are defined regardless of the orientation of the shield 220 or of the device 200, in the example of Figure 11, to which the shield 220 is substantially vertical, the region to which the Hair coloring spray is sprayed "above" shield 220, while the scalp to which the back surface 290 of the shield is pressed is "below" shield 220.

As indicated above, a function of the device 200 is to protect or shield the scalp "under" the shield from being directly subjected to the hair coloring agent provided as an aerosol. Another function of the device 200 is to facilitate the feeding of the hair coloring agent to the hair strands - for example, to the hair roots. Thus, shield 220 may include a plurality of relatively narrow grooves 480 (see Figure 11C) that are wide enough to accommodate strands of hair but not much wider. As illustrated in Figure 11C, these slots may in general be aligned with each other and / or in general aligned with the longitudinal axis 250 of the shield.

For the present disclosure, a groove at a given site (for example, at a "longitudinal site" having a value along the groove axis or tooth axis or longitudinal axis 250) may have a property of "covering the thickness of the shield "at a site if it is possible to travel the groove, at the given site, in the direction of" thickness / height "- that is, along the axis of the thickness of the shield 270. Thus, with reference to Figures 13B- 13C, it will be possible to "travel" through the groove at the site since it has the property of "covering the thickness of the shield" from region 704 up to region 702 (or vice versa).

The hair strands 310 rooted in the user's scalp run through the narrow grooves (that is, along the "shield thickness axis" 270 defined in Figures 13A-13C from the rear surface 290 to the front surface 280) to exit "above" the shield "to the region of space" above "the shield 702. As shown in Figure 11C, these hair strands 310 (or a portion thereof) can then be" co-located "With the spray of hair coloring sprayed in the region above the shield 702 and subjected to the spray coloring agent to facilitate the coloring of the hair roots.

In some embodiments, (i) the narrow 480 slots are of course narrow (having narrower width in the range of 0.2 mm to 1 mm - for example, at least 0.2 mm or at least 0.3 mm - for example, to at most 1 mm, or at most 0.8 mm or at most 0.7 mm or at most 0.7 mm or at most 0.6 mm) and (ii) shield 220 is geometrically structured to substantially lack other features (i.e. holes, holes, openings, etc.) that allow the aerosol to travel through shield 220 in a "down" direction along axis 270 from region 702 to region 704. Thus, it is possible to provide a device and method that will substantially locate the agent of coloring for aerosol-fed hair to the front surface 280 (and hereinafter, locating the aerosol-fed hair coloring agent to hair strands 310 or in some preferable embodiments or in some preferable embodiments to root strands of hair 310) of shield 220 while protecting the scalp that is located "under shield 220" in region 704.

Also, in some embodiments, due to the narrowness of the grooves 480 and / or the "density" of material in the space defined by the shield 220, the shield 220 is not really a comb. Instead, the shield 220 may be used to penetrate (to a certain degree) to the hair region substantially in the "border" region 490 between the hair mass and the wearer's forehead (see Figure 11) and / or in regions of parts of the hair (see Figure 12) - in some embodiments, it may be difficult for the penetrating shield of the hair to penetrate much deeper to the wearer's hair mass.

However, in many usage scenarios, a user colors or ticks a mayona of his hair from a "natural color" to a "target hair color" using any techniques known in the art. At a later time (for example, a few days or a few weeks later), the user's hair has grown in such a way that the roots of his hair are reverted to the "natural" color. In many of these use cases, instead of rectifying this situation by coloring the entire mass of hair (or even a significant fraction), the user is instructed to "touch up"

embarrassingly visible regions (for example, near the border region 490 and / or part of the hair 510). Where the hair roots have reverted to their natural color. Towards this end, in some embodiments, the shield may be useful for this purpose if the shield 220 may lack the "comb functionality" (that is, in some embodiments) and the use may be substantially confined to these regions of visible "border" of the hair.

In order to protect the scalp and / or provide "opportunities" for hair strands to travel up shield 220 to be exposed to the hair coloring agent provided in aerosol, shield 220 may in some embodiments provide a or more of the following features: (i) "thin elongated grooves" having a high "groove aspect ratio"; (ii) an arrangement of narrowly spaced teeth, wherein the teeth or the fords between the teeth have a "high aspect ratio"; (iii) teeth with a specific cross-sectional shape (for example, triangular) and / or one or more additional elements discussed herein. As will be discussed hereinafter, the "fineness" of the grooves or openings or spaces may be useful to prevent movement downward of even a non-viscous substance - since certain grooves or spaces or openings may still be wide enough to accommodate strands of hair (that is, whose width can be of the order of magnitude of one hundred or hundreds of microns), the "long groove" or "long ford" element may be useful to provide a large area where the strands of hair they can travel up the "shield" to a space above the shield, where the hair coloring agent (eg, aerosol drops) can coat the hair strands.

In another example (see Figure 15), individual teeth may have some kind of asymmetric width profile, where the teeth are wider (or conversely the "groove" or "gap" between teeth is narrower) "closer" to the lower surface 290 where the teeth are narrower (or conversely the "groove" or "space" between the teeth is wider) near the upper surface 280. As will be discussed hereinafter, the location of the "site of minimal space ”near the bottom may be useful to facilitate where the roots of the tooth, in particular are subjected to the hair coloring agent - for example, including black hair color and / or suitable hair coloring agent of“ coat ”the hair.

Another feature that may be provided by the device 200 whose use is illustrated in Figures 11-12 is the ability to "penetrate" the user's hair at a "border site" where the shield is oriented substantially parallel to the local plane of the User head

In order to facilitate penetration (for example, "shallow penetration" to all hair (for example, thick hair of an Indo-European or an African or an Asian) of shield 220 to a mass of air, may be it is useful to provide penetrating elements of the hair 240 (for example, see Figures 11C, 16-17) However, in some embodiments, due to the narrowness of the grooves 480 (also note the narrowness of "inter-tooth space" 370 that may define the narrowest location of the grooves 480-see Figures 17, 19, 21), the shield may provide diminished tooth functionality or no "comb functionality." In one example, "shallow penetration" is limited to 3 cm or up to 5 cm or up to 7 cm to "full hair".

Other features illustrated in Figures 11-12 that include the aerosol control 410, aerosol container 420, wherein the hair coloring spray can be stored before administration through the opening / exit 210 and device substrate or housing 230 that can provide mechanical connectivity or mechanical coupling between shield 220 and aerosol assembly 400. In a non-limiting example, aerosol assembly 400 can be directly or indirectly attached to shield 220 through any fastener known in the art , including but not limited to a fastener, a screw apparatus, a magnetic fastener or any other fastener known in the art. For example, the aerosol assembly 400 may be detachably attached to the shield 220. In another embodiment, the aerosol assembly 400 (or portion thereof) the shield 220 may be glued or welded together or formed integrally with each other.

Reference is now made to Figures 13A-13C which are side views of device 200 (or portions thereof). Figure 13A-13C illustrates the proximal ends 228 and 224 of the shield 220 that define a general "proximal-distant" direction 226. The distance between the proximal ends 228 and distant 224 is referred to as the "proximal-distant distance." In the example of Figures 11-13, the atomization (or some kind of "atomization vector" that defines a central tendency of the directions taken by the spray atomization fed from the aperture / outlet 210) can be along the proximal-distant direction 226 and / or generally aligned with the longitudinal axis 250.

In the non-limiting example of Figure 13B, the outlet / opening 210 through which the hair coloring spray is (i) fed is "elevated" above the substantially flat surface / substantially flat surface of the shield 220 for a distance marked 440 (in Figure 13B, the "extension" of the substantially flat surface of the shield 220 is marked 470) and (ii) moved in a direction near the end 228 for a distance marked 442. In In some embodiments, the "height" indicated by 440 may be at least 1 mm or at least 3 mm or at least 5 mm or at least 1 cm or at least 1.5 cm or at least 2 cm or by at least 5% and / or at least 10% or at least 20% or at least 30% of the “near-distant” distance and / or at least 1.5 times or at least 2 times or at least 3 times or at least 5 times or at least 7 times the average thickness of the shield 220. In some cases zaciones where armor

220 comprises an array of teeth comprising a plurality of substantially aligned teeth (see, for example Figures 15A-21D, the "height" indicated by 440 may be at least 1.5 times or at least 2 times or at least 3 times or at least 5 times or at least 7 times the average tooth thickness averaged over the teeth of the tooth arrangement.

In some embodiments, the "backward travel distance" indicated by 480 may be at least 5 mm, or at least 1 cm or at least 1.5 cm or at least 2 cm and / or at least 10% or at least 20% or at least 30% or at least 50% of a "near-distant distance" between the next 228 and distant 224 of the shield 220.

In some embodiments, the elevation and / or displacement of the aerosol outlet 210 in a distant direction may be useful for "creating some distance" between the aerosol outlet 210 and the shield 220. In some embodiments, if the aerosol outlet 210 is too close to shield 220, then the risk that the spray-fed hair coloring agent (for example, fed as a stream of droplets) will penetrate in a downward direction from region 702 and upper surface 280 through the shielding below the bottom surface 290 to regions 704 (where the scalp is) can be increased.

As indicated in Figure 13C, although the atomization (eg, a stream of drops) may initially exit the outlet / opening 210 in a direction that may be along the proximal-distant direction 226, the aerosol path it can be curved towards the shield 220 on the upper / upper surface 280 to contact and color the hair 310 that extends upwardly through the atomization shield (or some kind of "atomization vector" that defines the trend central direction taken by the spray atomization for coloring the hair fed from the opening / exit 210) can be along the proximal-distant direction 220 to the region 702 above the shield 220. In some embodiments, this atomization Hair coloring may include a quick-drying hair coloring agent and / or may include a “temporary” hair coloring agent that “wears out” after one or a few applications of hair shampoo and / or in a short period of time that is at least a few weeks or a few days.

As indicated above, the shield 220 may be useful for concealing the "down" movement (that is, from region 702 above the shield to the region 704 below the shield) of the hair coloring agent to a non-viscous .

In a non-limiting example, the non-viscous hair coloring agent may include a dye (eg, a basic hair dye) mixed with a non-viscous wearer, such as an alcohol-based carrier. In non-limiting examples, the drops are at least 5% or at least 10% or at least 15% by weight of alcohol. In a non-limiting example, the drop stream has a particular size that is less than 200 microns or less than 100 microns or less than 80 microns or less than 60 microns and / or at least 5 microns or at least 10 microns or at least 20 microns or at least 30 microns.

A "non-viscous" substance (eg, fluids) is a substance that "runs" or "flows" can have a viscosity that is less than 100 cps (and / or less than 100 times the viscosity of water at 20 ° C ) or less than 75 cps (and / or less than 75 times the viscosity of water at 20 ° C) or less than 50 cps (and / or less than 50 times the viscosity of water at 20 ° C) or less than 30 cps (and / or less than 30 times the viscosity of water at 20 ° C) or less than 20 cps (and / or less than 20 times the viscosity of water at 20 ° C) or less than 10 times (and / or less than 10 times the viscosity of water at 20 ° C) or less than 5 cps (and / or less than 5 times the viscosity of water at 20 ° C) or less than 3 cps (and / or less than 3 times the viscosity of water at 20 ° C) or less than 2 cps (and / or less than 2 times the viscosity of water at 20 ° C) or less than 1 cps (and / or less than the viscosity of water at 20 ° C) (cps is centipoises).

In some embodiments, a hair coloring substance that has "low viscosity" (eg, administered as a mist) can eliminate the need for the user to "comb" or "work" the hair coloring agent to the hair (as in the case of a fog). The user only atomizes the hair color to the hair and the drops (for example, that arrive directly from the aerosol spray opening and / or drops that bounce from other strands of hair) serve to coat the user's hair. In one example, this can take place without causing multiple strands of hair to stick together.

In some embodiments, the presence of a "high concentration" of a propellant (eg, an ether propellant) - for example, at least 15% or at least 20% or at least 20% or at least 30 % or at least 35% and / or the use of an alcoholic solvent facilitates the rapid drying of the coated hair strands - for example, within a few minutes.

Figures 13C-13D illustrate another view of the device 220 - for example a cross section of the area encompassed by the vectors of the thickness axis of the shield 270 and lateral axis 260 (the lateral direction of the lateral axis 260 is also illustrated in Figure 14) . There is no requirement that the shield 220 be flat or generally flat. In the non-limiting example of Figures 13C-13D, overall flat armor is "moderately concave down" to provide some kind of moderate shallow and broad cavity to which a portion of the user's scalp can be placed.

In some embodiments, the shield 220 may comprise a plurality of teeth, as illustrated in Figure 14. In the example of Figures 14-29 each tooth includes a respective main portion 330 and a respective distant portion 240. In some embodiments, The separation between the teeth (for example, a narrower separation or minimum separation distance 360 at a site between the upper part 246 and the lower part 248 of a pair of teeth) may be related to slots 480 discussed above.

In the non-limiting example of Figures 15-29, the shield 220 comprises an array of teeth comprising exactly two teeth. This is not a limitation. In some embodiments, shield 220 may include at least 5 or at least 8 or at least 10 or at least 12 or at least 20 or exactly 22 generally aligned teeth. In the non-limiting example of Figures 15A-21D, the teeth are all exactly parallel between naps is not a limitation. In some embodiments, the "generally aligned" teeth may be substantially parallel or may diverge from each other closer to the distant end 224 or converge.

A salient feature that can be provided by the teeth of the non-limiting example of Figure 15 is that these teeth are relatively long / tall and narrow and / or relatively long / tall and thin.

For the present disclosure, the "width" of a tooth (that is, anywhere along the axis of the tooth) refers to the dimension of the tooth along the lateral axis 260. As will be discussed hereinafter ( see Figure 21A-D) this width, for any particular tooth, may vary at different sites along the axis of the thickness of the tooth 270 (or along the axis of the tooth or along the longitudinal axis 250). In the non-limiting example of Figure 17A-B, 19A-B and 21A-D, the "width" and "bottom" of each tooth 248 is marked as 360, while the width near the "top" of Each tooth is marked as 350.

For the present disclosure, the "thickness" or "looseness" of a tooth is the dimension of the tooth along the axis of the thickness of the shield 270. As is evident from the figures, the height or thickness may vary along the axis. lateral 280 or along the axis of the tooth or along the longitudinal axis 250.

As indicated above, an outstanding feature may be provided by the teeth of the non-limiting example of Figure 14 is that these teeth are relatively long / tall and narrow and / or relatively long / tall and thin - that is, they may have a " large aspect ratio ”. In some embodiments, for each tooth for each arrangement of teeth of the shield 200 or for a mayonnaise of teeth of the arrangement of teeth (or at least 30% or at least 70% of the teeth of the arrangement of teeth - possible numbers of teeth of the arrangement of teeth are listed above), at least one of PROPORTION OF DlENTE 1, PROPORTION OF TEETH 2 and PROPORTION OF TEETH 3 may be at least 10 or at least 15 or at least 20 or at least 25 or at least 30 or at least 40.

PROPORTION OF TOOTH 1 is defined as the ratio between the length of the tooth and the average tooth width (that is, averaged for all sites on the tooth along the axis of shield thickness 270 and along the length of the tooth - either including or excluding the distant conic section 240 (probe section penetrating the hair 240)). The PROPORTION OF TOOTH 2 is defined as the ratio between the length of the tooth and the average tooth thickness (that is, averaged for all sites on the tooth along the lateral axis 0 260 and along the length of the tooth-ya either including or excluding the distant conic section 240 (probe section that penetrates the hair)). The PROPORTION OF TOOTH 3 is the ratio between the length of the tooth and the average cross-sectional tooth area (Figure 21A-D illustrates "slices" or cross sections of tooth) - the proportion of tooth 3 is averaged over the length of the tooth - either including or excluding the distant conic section 240 (probe section that penetrates the hair)).

Another outstanding feature that can facilitate the temporary coloration of hair roots while the scalp is protected is the feature where the "tooth" is relatively wide at the bottom of the tooth "while" relatively "narrow" near the top of the tooth.

In some embodiments, in order to provide this functionality, the cross section of the tooth can be triangularly formed - for example a wider base and a narrower upper part. This is illustrated in Figure 15.

Also illustrated in Figure 15 is the process by which hair with gray roots can be treated to coat the hair strand (for example, in the root) with black hair color. Thus, Figure 15A illustrates "before" the treatment, Figure 15B illustrates an example of the atomization process and Figure 15C illustrates the hair strands "after" treatment according to a non-limiting example.

In the non-limiting example of Figures 14-21, all teeth have identical shapes and cross sections (not necessarily of identical length) - this clearly or is a limitation and in some embodiments, there may be variation between the dimensions of the tooth and / or dimensions describing the geometric relationships of multiple teeth (for example, laterally adjacent teeth or laterally neighboring teeth) (for example, tooth spacing distance).

In addition, the cross section of the tooth may vary longitudinally along the "axis of the tooth" (not shown in the figures).

In addition, in the non-limiting examples of Figures 15-29, the teeth are exactly straight - that is, some kind of internal "tooth axis" (that is, the elongated axis or central axis of the tooth) always corresponds to the longitudinal axis. 250. This is not a limitation and even if the “local tooth axis” over a “very short” distance is a straight line, it will be appreciated that when a tooth is not perfectly straight, the axis of the central / elongated tooth (not shown) ) It can provide curvature or acute angles - instead of being a "straight line" it is possible to consider the tooth axis as a one-dimensional manifold in space that in many embodiments will generally be aligned with the longitudinal axis 250 and approach a straight line.

An outstanding feature that can be provided by the device of Figures 14-29 is that (i) the width of the tooth may vary over different "heights" in the tooth (for example, on the axis of shield thickness 270) and ( ii) this function of the width can provide a "profile of asymmetric width" (that is, referring to the width of the tooth in one or more sites along the length of the tooth - for example, in a majority of sites over the length of the tooth tooth or in a mayona of sites in a “given section” of the tooth whose length is at least 2 cm).

Some features described herein may be related to a "given section" or "control section" of the main portion 230 of a tooth or teeth (that is, a "longitudinal section" or a "longitudinal section") which is of at least 2 cm at least 5 cm or at least 3 cm or at least 3.5 cm or at least 4 cm. This "longitudinal" section can be located anywhere on the tooth. In some embodiments, this "given section" may be located near the far end of the end of the shield 220 - for example, longitudinally adjacent to (that is, bordering or less than 5 cm or 1 cm from) the conic distant section 240 ( for example, "probe shape" - for example that includes a rounded end).

In the non-limiting example of Figure 21, the cross section of the tooth has a triangular cross section (for example, a rounded isosceles triangle). Other forms of cross sections are possible, including but not limited to other examples of "substantially triangular cross section shapes."

In the example of Figure 21, the tooth has a relatively wide width at the point of the tooth 248 (for example, 360) and a relatively narrow width at or near the top part 246 of the tooth). Another outstanding feature of Figure 21 is that the minimum separation width for the cross section (that is, between laterally adjacent pairs of the tooth) - for example, the separation 3701 between the teeth 330I and 3300J) is located near or in the part lower tooth 248.

By locating this "minimum separation" near the bottom of the tooth, it is possible that the root of the hair strand 310 is located within the region 390 empties between laterally adjacent teeth above the site of the minimum separation distance 370. In some embodiments, it may be useful or important to allow the root of the hair strand 310 (instead of just a more distant site within the strand beyond the root) to travel the site of the minimum separation distance 370 and exit above from this site to the empty region 390 between the teeth above the "undulating" upper surface 280 of the shield, defined by the upper surface of the teeth. Because the hair strand root (and not just an upper site of the hair strand) is located in the "spray-exposed" region 702 above the upper surface 280, instead of the "spray-like" region shielded ”704 below a site of the minimum separation distance 370 (and below the lower / lower surface 390 of the shield 220), this“ minimum space extension ”hair root can be subjected to the hair coloring agent provided by hair penetration spray penetration.

In some embodiments, the average or individual empty cross section (that is, for a longitudinal section that is at least 2 cm or at least 2.5 cm or at least 3 cm or at least 4 cm or at least 5 cm or longer) can be (that is, either for a single tooth or a single groove or for an arrangement of any number of teeth or grooves or voids - that is, either on average for the arrangement or individually for any number of grooves or teeth or voids) at most 6 mm2 or at most 5 mm2 or at most 4 mm2 or at most 3 mm2 or at most 2 mm2- in some embodiments, the average or individual hollow cross-section may be at least 0.5 mm2 or at least 1 mm2. This "hollow cross section" can prevail on average over the section or it can prevail for at least one significant minona of sites, at least the mayona of sites (synonymously "for the mayona of the sites") or at least one mayona significant or very significant mayona of section sites. This may be true on average for any number of teeth of an array of teeth (or voids formed therefrom) or any number of slots or voids of a groove / span arrangement and / or individually true for a significant minona or mayona or significant mayona or very significant mayona of teeth (that is, the resulting spaces formed therefrom) of the arrangement of teeth.

In some embodiments, the average or individual cross section of teeth (that is, for a longitudinal section that is at least 2 cm or at least 2.5 or at least 3 cm or at least 4 cm or at least 5 cm or longer (it can be (that is, either for a single tooth or for any number of teeth-that is, either on average or individually for an arrangement of any number within a tooth arrangement) at most 6 mm2 or at most 5 mm2 or at most 4 mm2 or at most 3 mm2 or at most 2 mm2-in some embodiments, the cross section of the average or individual void can be at least 0.5 mm2 or 1 mm2. cross section of the tooth ”can prevail on average over the section or it can prevail by at least one significant minona of sites, for at least the mayona of the sites (synonymously“ for the mayona of the sites ”) or at least one mayona significant or very significant mayona of section sites.

As can be seen from the figures, the "upper surface of the hollow regions 390" and / or "the upper surface defined by joining the upper sites d246 of the teeth" (this is marked by 340) can deviate from the "surface higher / higher ”280 of the shield or teeth (for example, above the“ minimum separation site ”of the“ minimum separation distance ”370).

An outstanding feature observable in Figure 21 is that the upper surface 280 is relatively rough or rough with oscillating heights (along the lateral axis) while the lower surface 290 is relatively smooth 290 (and a local level, can be substantially flat ). In some embodiments, the geometry where (i) the lower surface 290 is relatively smooth and where (ii) the smallest separation site of the minimum separation distance 370 is closest to or at the bottom 248 of the teeth is useful. to help the hair strand 310 travel the minimum separation site 370 in the hair root. On the other hand, if the minimum separation distance 370 was higher and / or if the bottom / bottom surface had large "vertical / height" variations, this could, at least somewhat (without departing from the scope of the invention ), reduce the effectiveness of the device because the hair coloring will have to be concentrated in higher places on the hair strand 310 instead of the root.

The previous paragraph (and any other feature or figure described therein) refers to some features that may be provided by some embodiments - this is not intended to be limiting.

In some embodiments, because the upper surface 280 may tend to undulate or oscillate along the lateral axis while the lower surface may lack such undulations / oscillations (or may only be present to a slight extent), the "surface upper 280 "may be a rough or rough surface (that is, have a rough or rough topography), while the lower surface 290 may be a" smooth "surface. This can also be observed by comparing Figure 15 and Figure 16 with Figure 18, while the width of the front surface teeth can vary significantly between the top and bottom of the teeth (compare 350 and 360) in the front side (looking down), in Figure 18, it can be seen that the rear surface 290 is significantly smoother. In Figure 18, the posterior surface 290 includes wider teeth (that is, the or near the bottom 248 - as opposed to the front surface when viewed by the width may vary significantly) punctuated by relatively narrow separations 370.

In a non-limiting example, the "minimum separation width" 370 of the narrow separations is at least 0.2 mm or at least 0.3 mm or at least 0.4 mm. In a non-limiting example, the "minimum separation width" 370 of the narrow separations is at most 1.2 mm or at most 1 mm or at most 0.8 mm or at most 0.7 mm or at most 0.6 mm. This can be for any number of teeth of an array of teeth (that is, significant minona, mayona, significant mayona, very significant mayona) and / or averaged over any length of tooth or groove (that is, for a "section" by at least the significant site minona, at least the site mayona or synonymously "the mayona of the sites or at least the significant mayona or very significant mayona of sites").

In Figure 21D, the "highest site" or "top" of several teeth are marked as 246. The "bottom" point or lowest point on the axis of shield thickness 260 is marked as 248. The point " medium ”(this may be a little deep if the upper part of the bottom of the teeth is a point site) 249 are also illustrated in Figure 21D. However, all points of the "point site for 249" (or the midpoint of the upper point) have the same "height" 923 above the bottom 248-see also Figure 23C.

In some embodiments, for a mayona (or a significant majority - that is, at least 70% or 80%) of sites within 2 cm of the "control section" or "given section" of the tooth, the ratio between the "maximum width 360 of the tooth" (in some embodiments, the maximum width 360 may be located in the lower half or 30% lower or 20% lower or 10% lower of the tooth-where the upper sections and lower sections of the tooth are defined along the axis of thickness 270 and in relation to the upper part 246 and lower part 248 of the tooth) and the "minimum separation distance" 370 can be at least 1.3 or at least 1.5 or at least

1.7 or at least 2. The person skilled in the art is directed, for example, to Figures 19A and 18. This "characteristic of proportion" can be provided in a "set of teeth" of at least 2 or at least 3 or at least 4 or at least 5 or at least 10 or at least 12 or at least 15 consecutive teeth. In some embodiments, this feature may be provided in such a way that for the "adjacent separation pairs" mayona 370 (in Figure 17A, 370I and 370J are "adjacent separation pairs-370I and 370K are not" adjacent separation pairs ”) The distance between adjacent“ separations ”370 (or in some embodiments, the average distance between the pairs of adjacent separations) is at most 2 cm or at most 1.7 cm or at most 1.5 cm.

It is possible to define a “fill factor” of a 2D surface of a 3D space volume (that is, a “control area” or “control volume”) that includes both (i) “shielding material 220” or “ 330 ”tooth matter (per

for example, plastic or any other appropriate material) also as (ii) empty or empty space (for example, 390 or 702 or 704). The "fill factor" refers to the proportion of: (i) the total area (or volume) within the "control area" ("control volume") that is occupied by matter divided by; (ii) the total size (that is, area or volume) of the control volume.

An example of a "control" volume is illustrated in Figures 22A-22B (marked by 810). The "measurement" or "length" of the control volume in the longitudinal dimension 250 may be at least 1 cm or at least 2 cm or at least 3 cm. The "measurement" of "length" of the control volume in the "transverse direction" 260 may be at least 0.5 cm or at least 1 cm or at least 1.5 cm or at least 2 cm. In some embodiments, the "fill factor" may be at least 60% or at least 70% or at least 75% or at least 80% or at least 85% or at least 90% or by at least 95%

The control area or the control volume can be substantially flat - for example, in a lateral direction, following the contour of a medium line or average curve of the shield (ie, "midpoints" of adjacent teeth joining where medium is defined by the "average location" of the upper part 246 and lower part 248 of the tooth) following the contour of the bottom / bottom surface 290.

In some embodiments, in the direction along the "lateral direction" along the lateral direction, the control area or the control volume includes a plurality of elongated grooves (that is, these grooves are "ford" and they may correspond to the "minimum separation 370" or a site slightly above or below), each slot being at least 0.5 cm or 1 cm or 1.5 cm or 2 cm in length, where either (i) the "distance lateral between laterally adjacent grooves ”average is at most 4mm or at most 3mm or at most 2.5mm or at most 2mm and / or (ii) a slotted mayonnaise (or a significant slotted mayonnaise- for example, at least 70% or 80% of the grooves) have an average longitudinal width that is at least 0.2 mm or at least 0.3 mm and at most 1.2 mm or at most 1 mm and at most 0.8 mm or more than 0.7 mm or more than 0.6 mm; (iii) a ratio between an average groove-groove side distance and an average groove width is at most 4 or at most 3 (if this ratio is "too high" and / or the grooves are "laterally spaced" this it can "reduce the chances of strands of hair extending upwards and running through shield 220").

Figure 23 is concerning a use case where the cross section of not all teeth is the same. In Figure 23A, the upper part of the tooth is 246, the lower part is 248 and the "midpoint" or line is 249. This line can delineate two regions - a "higher region" above 249 closer to the upper part 246 of the tooth (this region on average will be narrower) and a "lower region" below 249 closer to the lower part 246 of the tooth (this region on average will be narrower).

In some embodiments, provide it between (i) the cross sectional width is the average in this "lower region" below 249 and (ii) the average cross sectional tooth width in this "highest region" above 249 it can be at least 1.1 or at least 1.2 or at least 1.3 or at least 1.4 or at least 1.5 or at least 1.6 or at least 1.7 or at least 1.8 or at least 1.9 or at least minus 2 or at least 2.5

The width of "average tooth cross section" can be averaged according to any technique disclosed herein — for example, longitudinally on the axis of the tooth in a certain region of the entire teeth and / or between any set (or subset) of teeth of the tooth arrangement.

In Figure 24B, the "upper region" is defined as above point 911 (a% of the path to the upper part) while the "lower region" is defined as below point 909 (a% of the path to the bottom).

In some embodiments, the ratio between (i) a cross-sectional width of the average tooth in this "lower region" below 909 and (ii) a cross-sectional width of the average tooth in this "highest region" above 911 it can be at least 1.3 or at least 1.5 or at least 1.7 or at least 2 or at least 2.5 or at least 3 or at least 4 or at least 5 or at least 7 or at least minus 10. The width of "cross section of the average tooth" can be averaged according to any technique disclosed herein — for example, longitudinally on the axis of the tooth in a certain region of the entire tooth and / or between any set ( or subset) of the tooth arrangement.

In Figures 23C-23D, it is shown that the ford or groove 390 may, in contrast to the teeth, be "wider near the top" ("near the top" is defined as above the average height level 293 in Figure 23C and above% of the height level 925 in Figure 23D) and "narrower near the bottom" ("near the top" is defined as below the average height level 923 in Figure 23C and below a quarter of height level 927 in Figure 23D).

The height ratio (that is, the average height in the widest region divided by the average height in the narrowest region) for the ford (that is, the “widest region is the top” and the “narrowest region "Is the background but the principle, for at least the example of Figure 23, may be similar). Thus, the height ratio for the ford can be for Figure 23C (that is, any case of the "average height level") at least 1.1 or at least 1.2 or at least 1.3 or at least 1.4 or by at least 1.5 or at least 1.6 or at least

1.7 or at least 1.8 or at least 1.9 or at least 2 or at least 2.5 and for Figure 23D (any case of the fourth or three-fourth level) at least 1.3 or at least 1.5 or at least minus 1.7. or at least 2 or so

minus 2.5 or at least 3 or at least 4 or at least 5 or at least 7 or at least 10.

As indicated above, in some embodiments, the tooth may have an asymmetric width profile, where the region closest to the bottom 248 of tooth 330 tends to have a wider / larger width, while the region closest to the part upper 248 of tooth 330 tends to have a narrower / smaller width. As indicated above, this can lead to a situation where the upper / upper surface 280 of the shield 220 has a relatively rough or rough topography (e.g., undulating) while the bottom / bottom surface 290 of the shield 220 has a relatively "smooth" topography.

In some embodiments, if a small cylinder 850 was moved (for example, having a length of 1 mm or 2 mm or 3 mm or 5 mm or 1 cm or 1.5 cm or 2 cm or 2.5 cm) in a lateral direction on the surface upper 280 (for example, for each pair of teeth limited in the lower part by the location of the minimum separation 370) because the upper surface of rough topography, this cylinder moves up and down as the small cylinder it is moved on top surface 280-this is shown in the tables of Figures 24A-24F.

Various numbers describing possible cylinder sizes may either refer to the cylinder radius or cylinder diameter. In one example, the cylinder 850 has a radius or diameter of 0.6 mm. In another example, the cylinder 850 has a radius or diameter of 0.8 mm. In one example, the cylinder 850 has a radius or diameter of 0.6 mm. In another example, the cylinder 850 has a radius or diameter of 1 mm. In one example, the cylinder has a radius or diameter of 0.6 mm. In another example, the cylinder 850 has a radius or diameter of 1.3 mm.

Possible mm cylinder radii (or mm diameters) are: 0.4 mm, 0.5 mm, 0.6 mm, 0.8 mm. 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm and 2 mm. Maximum possible cylinder radii (or maximum diameters) are: 2.5 mm, 2 mm,

1.8 mm 1.6 mm, 1.4 mm. 1.2 mm, 1 mm, 0.8 mm and 0.4 mm - intervals can be formed by mixing any of mmimo and any maximum (for this feature or any feature here).

In Figures 25A-25B, the cylinder path of the "experiment" of Figure 24A-F is illustrated - the magnitude / size (that is, in the "height direction") of the undulations and / or oscillations is given by OSC1 and can be at least 0.4 mm or at least 0.6 mm or at least 0.8 mm or at least or at least 1 mm or at least 1.2 mm or at least 1.4 mm or at least 1.6 mm or at least 1.8 mm or at least 2 mm. This magnitude of "oscillation" or "undulation" (which finally describes surface 280) can be obtained on "different" occasions (that is, separated in the "lateral direction" by at least 1 mm or by at least 1.5 mm or by at least 1.8 mm or at least 2 mm or at least 2.5 mm) along the lateral directions - at least 3 times or at least 5 times or at least 7 times or at least 10 times or by At least 13 times. In a non-limiting example of Figure 24A, the lateral separation distance between these "different occasions" corresponds to the substantially periodic form (that is, in the lateral direction 260) of the surface 280. However, it will be noted that it is not Requires surface 280 to be periodic.

In Figure 26, the experiment of Figure 24 is repeated, with the same cylinder for the "bottom / bottom 290" surface. In Figure 27, the trajectory, the magnitude / size (that is, in the "height direction") of the undulations and / or oscillations is given by OSC2 and can be at most 1 mm or at most 0.5 mm or at most 0.3 mm or at most 0.3 mm or at most 0.1 mm. In some embodiments, in order for OSC2 to "count", it needs to be presented only once. In some embodiments, it needs to be presented at least 2 or 3 or 4 or 5 or 7 times in "different side sites" separated by at least 1 mm or 1.5 mm or 2 mm.

In some embodiments, OSC1 is greater than OSC2 such that the ratio between OSC1 and OSC2 is at least 2 or at least 3 or at least 5 or at least 7 or at least 10. It will be understood that for The rounded triangles OSC1 / OSC2 can be quite large - however, for other shapes that are also substantially triangular (for example, if there is some kind of structure "below" the base, then OSC1 / OSC2 may not be as large.

Various embodiments of the present invention may relate to: methods of coloring the hair (for example, with a hair coloring agent in aerosol); hair coloring devices (for example, which include shield 220 and an aerosol assembly 400), hair coloring kits (for example, which include shield 220 and an aerosol assembly 400 or a portion of an aerosol assembly ) and shields 220 configured to be useful for hair coloring. Thus, in some embodiments, the shield 220 and aerosol assembly 400 may be sold separately or as a kit (for example, permanently attached to each other or permanently attached).

Thus, any "system or device that includes a shield and an aerosol assembly" can also be provided as a "kit that includes the shield and the aerosol assembly" where the shield and aerosol assembly can be coupled to each other (by example, set when holding at least one portion between sf).

In a non-limiting example, a single kit includes an aerosol assembly and shields 220 of multiple lengths - for example, a "short shield" of a longitudinal length (for example, from the tip to the base of the tooth) of less than 4 cm or less of 4.5 cm and a “long shield” of a longitudinal extension (for example, from the tip to the base of the tooth) of more than 5 cm or more than 5.5 cm or more than 6 cm or more than 6.5 cm ( that is, any

combination).

Figure 28 describes a routine for assembling such a kit to a system currently disclosed.

Figure 29 is a flow chart of use of a hair coloring device (see Figures 11-12 as well).

Figure 30 describes an aerosol assembly - for example, the hole has a width of 0.3 mm in Figure 30A, the relatively small drop form (for example, less than 100 microns average or less than 80 microns or less than 60 microns or less than 50 microns) -asf, the width of the hole may be less than 0.6 mm or less than 0.5 mm).

An outstanding feature of Figure 30B is a "rectangular-shaped atomization insert" (for example, the ratio between length and width is at least 1.2 or at least 1.4, such that the atomization produced ( see the dotted line showing a mainly horizontal atomization form) is a fan atomization, for example having a substantially rectangular cross section.

General discussion of features

As indicated above, some embodiments of the present invention are concerned with an arrangement of elongate grooves or an arrangement of elongated teeth. It will be appreciated that various properties of teeth or grooves (for example, concerning the width profile, aspect ratio, cross-sectional shape, separation distance near the teeth) may not be required to prevail for a majority of teeth and / or for a majority of sites along the axis of the tooth or elongated groove (that is, within the entire tooth or groove or within a given elongated "section").

For any characteristic or combination of features disclosed herein for a "mayonnaise of teeth" (that is, of a plurality of teeth) or a mayona of fords or grooves (that is, for a plurality of fords or grooves) this characteristic also it can be applied (that is, any feature or combination of features), in alternative embodiments, to a "significant minona" (that is, at least 30%) or to a "significant mayona" (that is, at least 70% ) or a "very significant mayona" (that is, at least 90%) of teeth or frogs or grooves.

Similarly, for any feature or combination of features disclosed herein, for the "mayona of the sites" (that is, for at least 50% of the sites) within a "section" of a tooth, groove or ford or the shield (that is, along a longitudinal axis or central axis) along a longitudinal axis and / or along the length of the tooth and / or along a groove length or length of ford between neighboring teeth, this feature can also be applied to the “significant minona” (that is, at least 30%) of sites within the sector or to a “significant mayona” (that is, at least 70%) of sites in the section or a "very significant mayonnaise" (that is, at least 90%) of teeth of sectional sites along a longitudinal axis.

Some features (or combinations of features) are disclosed for "tooth sections" or "shield section" that has a given length. For any feature or combination of features, this length can be at least 2 cm or at least 2.5 cm or at least 3 cm or at least 3.5 cm or at least 4 cm.

When a feature (or combination of features) is disclosed for a significant mayona or minona or significant mayona or a very significant mayona of a number of grooves or fords or teeth, this number of teeth or grooves or fords may be at least 8 , at least 10, at least 12, at least 14, at least 16, at least 18 or at least 20 for any feature (or combination) disclosed herein.

Any discussion of “mayona” can also be applied to “significant minona” (at least 30%) or “significant mayona” (that is, at least 70%) or a “very significant mayona” (that is, at least minus 90%)

The person skilled in the art will know how to choose appropriate materials from which the shield or any other component should be constructed. In a non-limiting example, the shield is constructed of plastic or any other material evident to those experienced in the art after reading the present disclosure.

In some embodiments, a kit for constructing any system currently disclosed is described. The kit may include: (i) a penetrating hair shield and (ii) an aerosol assembly that when coupled to each other can produce any hair coloring device currently disclosed (i.e., that includes both the shield and the set of spray).

In one example, a single kit may include multiple shields, such as a longer shield and shorter shield. The length ratio (that is, where the length is along the longitudinal direction) between the length of two shields can be at least 1.3 or at least 1.5 or at least 1.7 or at least 2.

In some embodiments, any kit may include instructions for combining and / or attaching the spray assembly and hair shield (for example, according to Figure 28).

In some embodiments, when the "quick-drying" hair coloring composition is fed to the hair (for example, to coat the hair), it can dry on the surface of the hair in less than 8 minutes or less than 6 minutes or less 4 minutes or less than 2 minutes.

Generally speaking, a "quick-drying" composition or agent dries faster than water. In one example, when a drop (for example, from a drop applicator) of the "quick-drying" composition or agent is placed on a porcelain plate at room temperature conditions, it will dry faster than water (that is, subjected to a similar porcelain plate experiment). In some embodiments, the drying time of the composition or "rapid drying" agent may be closer to the drying time of alcohol (that is, subjected to an identical porcelain plate experiment) than the type of water drying.

An outstanding feature of Figure 11 is that the shield is relatively long and narrow. In some embodiments, the length ratio to the width of the shield of at least 1.25 or at least 1.5 or at least 1.7 0 at least 2. The use of a "narrow shield" (that is, whose width is a at most 5 cm or at most 4 cm or at most 3 cm or at most 2 cm) may be useful for treating “sensitive areas” although this is not a requirement.

A second additional discussion

Referring now to the figures, Figure 1-5 illustrates a hair coloring applicator constructed in accordance with the present embodiments and particularly useful for retouching the hair along a hair line quickly and conveniently.

As shown particularly in the detailed view of Figure 5, the hair coloring applicator comprises four main components: a container, generally designated 10 to contain an amount of hair coloring composition; an accessory 20 attached to one end of the container 10; a shield 30 carried by the accessory and an external housing 40 enclosing the container 10 and serving as a handle to hold and manipulate the applicator.

As clearly seen in Figure 5, the recent 10 is an aerosol container of cylindrical configuration and can be of any known construction. It includes an amount of the amount of composition to color the hair to be assorted, which may be in powder form or liquid form; preferably, it also includes a propellant gas to fill the hair coloring composition in the form of an atomization. One end of the aerosol container 10 includes an outlet 12 in the form of a nozzle through which the composition is stocked and a valve indicates with 14 that it is normally closed but that it is open after tilting or pressing the nozzle 12 to fill the nozzle. composition in the form of an atomization through the nozzle.

The accessory 20 is removably attached to the end of the aerosol container 10 that includes the nozzle 12. The accessory 20 includes a shield 30, which, as will be described more particularly below, exposes the root regions of the hair to be retouched, The atomization of assorted hair coloring composition through the nozzle 12 when the valve 14 is open, while at the same time effectively blocking the scalp of the individual from being exposed to the atomization of the hair coloring composition. The shield 30 is fixedly attached to the accessory 20 but can also be removably attached thereto for replacement or cleaning purpose. The shield and / or accessory can be constructed for one-time use or for repeated use.

The lower end 21 of the accessory 20 is of cylindrical configuration and has an internal diameter substantially equal to the external diameter of the aerosol container 10. One side of the accessory 20 is formed by an upper wall

inclined 22 ending in an upper flange 23 formed by a projection 24 to receive the shield 30 with a friction adjustment or insertion adjustment. When the accessory 20 is applied on the upper end of the aerosol canister 10, an opening 25 in the inclined wall 22 is aligned with the nozzle 12 of the aerosol canister, while a push button 25 is aligned with the valve 14 of the canister. aerosol. The construction is such that after pressing the push button, the nozzle 12 of the container is inclined or pressed to open the valve 14, to thereby produce an atomization of the hair coloring composition on the external surface of the shield 30 a through the opening 25 in the accessory.

As seen particularly in Figure 5, the opening 25 of the accessory 20 is located between the pressed button 26 and the shield 30 attached to the peripheral wall 23 of the accessory. The nozzle 12 and the opening 25 in the accessory are oriented to produce a fan-shaped atomization directed towards the proximal (internal) end of the shield.

The shield 30 includes a plurality of spaced teeth 31 that extend substantially parallel to the longitudinal axis LA of the recent aerosol 10 and integrally formed with a groove 32 that extends substantially perpendicular to the longitudinal axis LA. As shown particularly in Figure 3, the teeth 31 of the shield 30 are arranged in a substantially linear arrangement, such an arrangement is displaced from the longitudinal axis LA of the aerosol can. The teeth 31 are small in width and thickness and closely spaced. Preferably, they are less than 2 mm in width, thickness and spacing and are conical to point at their outer tips.

As will be described more particularly below, when the applicator is used to retouch the hair along a hairline, the applicator is manipulated such that the surface 30a of the shield 30 serves as an internal surface pressed against the scalp. of the individual, while the surface 30b serves with an external surface that is exposed to the spray composition of assorted hair coloring of the nozzle 12 of the aerosol container 10 through the opening 22 of the accessory 20.

As shown in Figure 5, the external housing 40 of the applicator is also of a cylindrical configuration corresponding to the cylindrical configuration of the aerosol container 10. The internal diameter of the housing 40 is substantially equal to the external diameter of the aerosol container 10 to receive closely the aerosol container and act as a handle to hold and manipulate the applicator. Preferably, the upper surface 41 of the external housing 40 and the internal flange 27 of the accessory 20 are of complementary curved configurations to present a pleasing appearance to the applicator when all parts are assembled as shown in Figures 1 and 3, for example.

The manner of using the applicator of Figures 1-5 will be apparent from the above description. Thus, after all the parts have been assembled, as shown in Figures 1-3, the user holds the external housing 40, orients the shield 30, such that the surface 30a is facing and is pressed against the leather scalp of the individual and manipulates the applicator in such a way that the hair root regions along the hairline to be retouched are received in the spaces between the teeth 31. Then the user presses the push button 26 to produce a atomization through the nozzle 12 on the outer side 30b of the shield 30, while the shield is moved along the hairline to be retouched. The atomization thus produced from the hair coloring composition covers the root regions of the hair exposed by the teeth 31 at the proximal end of the shield 30, while the rest of the shield effectively blocks the passage of the atomization of the coloring composition. from the hair to the scalp of the individual.

After the hair coloring composition has been depleted of the aerosol container 10, the carrier 40, accessory 20 and shield 30 can be disassembled and applied to a new aerosol container 10.

The hair coloring applicator illustrated in Figure 6-10 is also basically constructed of the same parts as the applicator of Figure 1-5, that is, it includes an aerosol container 110 (Figure 10), an accessory 120 applied to one end of the aerosol canister, a shield 130 carried by the accessory and an external housing 140 that encloses the aerosol canister 110 and serves as a handle to hold and manipulate the applicator.

The main difference in the applicator illustrated in Figures 6-10 with respect to that illustrated in Figures 1-5 is that the external housing 140 and the accessory 120 are not cylindrical in configuration, but rather of a substantially square configuration with corners rounded, to present a more comfortable grip of the applicator when handled, also as an external appearance more pleasant to the applicator.

In all other aspects, the applicator illustrated in Figure 6-10 is constructed and used substantially in the manner as described above with respect to Figures 1-5.

While the applicator has been described with respect to two preferred embodiments, it will be appreciated that these are summarized only by example purposes and that many other application variations can be made. For example, instead of using an aerosol container to supply the hair dye in the form of an atomization, a container or pump may be used where the push button 26 is effective for pumping an atomization of the hair dye, in instead of opening a valve that allows the fluid inside the container to produce a
