EP0890326B1 - Tool for dyeing hair during combing and specific dyeing device - Google Patents

Description

The present invention relates to a tool for coloring hair, or hair, by styling, without coloring the skin. The tool is a brush, or a comb, having the originality of being itself the support of coloring products. This tool does not require any manipulation of product, it is ready to use, it is disposable. It is provided with a specific coloring device and scalable. One of its particularities is to be able to spread the coloring product on the hair without coloring the skin of the scalp. Its action produces its effects by simply passing the tool in the hair, or the hair. The range of colors can go to infinity.

Usually, the coloring processes are done by direct application, on the hair and the scalp, a liquid, gelatinous, or cream product. These processes require delicate implementation, and a certain technicality, in order to avoid mottling on the hair, drips on the epidermis and possible splashes around.

We know from document EP-A-168 741 an instrument for the cosmetic treatment of hair in the form of a comb, a brush or a flap brush. This instrument has teeth, bristles or lamellae of microporous polymer material filled with solutions of treatment products.

The amount of applicable treatment product is limited by the absorption capacity of the polymer material. Furthermore, the correct distribution of the product application is not optimized.

This invention is intended for both men and women. Men don't not necessarily wishing to undergo permanent coloring in a hair salon, or even that the thing be official. Women will find a simple and quick way to revive their color, camouflage their white hair, give a new reflection or a new color to their hair. The tool is compact, it is clean, discreet, it can slip into a bag hand, toiletry bag or pocket.

FIG.1 - This is the basis of this invention which proposes to make a tool of simplicity absolute use. It consists of a body of variable shape (1) and its handle (2), serving as a support for the coloring device (3): consisting of a spongy body or a tank (3), and colored diffusers (4) called cylinders, they are attached, stamps, and impregnated with coloring pigments, from its conception the whole is adjusted to the shape of the body (1), and fixed thereon. For the production of this tool, different materials can be used, such as hardwood, plastic and its derivatives for the body (1) and the handle (2). For the structure constituting the coloring device (3) and its diffusers (4), various other kinds of polymers are used such as high density foam and its derivatives, felt or a porous wood such as balsa, impregnated with pigments,

The dyes are of different types, they are natural pigments extracted from plants, or synthetic, and, or, with oxidizing power, these are known and hypoallergenic.

Its active part, or coloring device (3) (4), is composed either, directly of paste dye solidified and molded in the form of a brush, either by impregnation of the spongy support (3), and its cylinders (4) either by pressure diffusers (4), fig.4. All these materials can enter into the composition of the brush, either individually or in combination.

This invention has two purposes, either to make up white hair, or to revive a fancy coloring, here called process N ° 1, that is to obtain a more tenacious coloring in two-stroke, process N ° 2. Discreetly, at home or while traveling.

The novelty of this invention results from the marriage of a usual tool, the brush, or the comb, for which all the variants of shapes are possible, and of an incorporated dye.

• Le procédé N°1: prenons pour exemple du Balsa en (3) et (4), qui est un bois poreux, il est imbibé à chaud par le produit colorant. Ce matériau restitue la matière colorante adéquate telle que décrit antérieurement, par simple frottement, en passant la brosse, ou le peigne, dans les cheveux.

By analogy, the comparison is made with a felt-tip pen, ready to use and disposable.

• Process N ° 1: take for example Balsa in (3) and (4), which is a porous wood, it is soaked hot with the coloring product. This material restores the adequate coloring matter as described above, by simple rubbing, passing the brush, or the comb, through the hair.

This material being fragile, it must be glued to the rigid support (1), which is plastic or hardwood ending in a thicker handle (2). Diffusers (4) can be of shapes different, worked in the mass, molded, or implanted, their length is variable, between 0.2 and 2.5 cm. (4).

• Le procédé N° 2 : il utilise la même conception et le même principe.

The size and size of this tool can vary, in this case, they are 15 to 17 cm in length with its handle (1) + (2), between 2 and 4 cm in width, for a thickness of 1 at 4 cm, bristles included. For the support, all variants of shapes are possible; The invention which is the subject of the present description being the combination of the materials mentioned above, and incorporated coloring pigments.

• Process N ° 2: it uses the same design and the same principle.

Its difference lies in the choice of pigment. This is a pigment that can oxidize. he therefore deeply modifies the pigmentation of natural hair. This color become a stubborn coloring.

• La plus originale et intéressante dans le cadre de cette invention, est d'incorporer directement le produit réactif lors de la conception de la brosse, sous forme de pâte solidifiée; Un diffuseur (4) sur deux est du pigment, un diffuseur (4) sur deux est un oxydant. Un rinçage est nécessaire après 15 mn.

In the case of the use of an oxidizing pigment, two variants are available to us.

• The most original and interesting in the context of this invention, is to directly incorporate the reactive product during the design of the brush, in the form of solidified paste; One in two diffusers (4) is pigment, one in two diffusers (4) is an oxidant. Rinsing is necessary after 15 min.

• La seconde variante consiste à ne déposer que des pigments oxidant sur les cheveux lors du passage de la brosse, dans ce cas il est nécessaire d'appliquer à posteriori un produit réactif, en crème, ou en mousse, provoquant ainsi l'oxydation des pigments sur les cheveux. Ceci nécessite 15 à 20 mn de pause et doit être rincé.

In this case a flexible sheath, or a protective cover on the bristles is necessary (5).

• The second variant consists in depositing only oxidizing pigments on the hair during the passage of the brush, in this case it is necessary to apply a posteriori a reactive product, in cream, or in foam, thus causing the oxidation of the pigments. on the hair. This requires a 15-20 minute break and must be rinsed off.

The brush manufacturing technique is not changed in any way.

FIG.2 - This color distribution device is part part of the system. It contributes fully to the invention. It is important to explain how to spread the coloring product on the hair without coloring the skin of the scalp.

This device consists of a cylinder, of variable shapes, straight, conical, ovoid or comprising flats (4), of various materials, having a liquid retention capacity.

The height of the cylinder varies between 0.2 and 2.5 cm, its diameter between 0.1 and 0.8 cm. His center is drilled by a hole (6) proportional to its diameter, between 0.05 and 0.2 cm.

This hole (6) receives a round head, nail-shaped element (7), the material of the head is rigid and water-repellent, this nail-shaped element (7) is screwed in force, or stamped in the hole (6); the thickness of the nail head (8) varies between 0.05 and 0.2 cm depending on the cylinder diameter (4).

This round head element (7) is essential in order to isolate the dye distributor cylinder from the scalp.

This cylinder (4) is molded with its support (3) or implanted in it, it is duplicated in order to constitute an object resembling in its use a brush or a comb. The cylinder (4) is supplied with product by osmosis with its support, or its reservoir (3), absorbs content. The product is distributed over the hair by friction, its round head (8) independent and not impregnated with dye isolates the scalp leaving no trace of color on the skin.

The dye product holder can be in the form of a disposable refill, it can be clipped onto the body of the tool in the form of a brush (1), or mounted on a slide in order to ability to interchange colors.

FIG.3 - This description is a second variant of the cylinder insulation system, it brings the same protective effect to the skin. Just insert between the cylinders product distributors (4), a rigid bristle with a round head (9). Its height is greater than the cylinder product dispenser (4) to create an insulating space. In this case the cylinder (4) has neither hole or nail. Its production and operation are identical to the basic invention described upper.

FIG.4 - This device according to the invention uses under the same conditions as described above hollow cylinders pierced with holes (10) to distribute the color. Insulation with the scalp is obtained by a solid ball (11) at the end of the cylinder distributor (4). In this case the coloring product has a gelatinous consistency. To get a better spreading of the coloring product, bristles (12) are implanted between the cylinders, their heights is less than that of the cylinders.

The coloring product contained in the reservoir (3) is injected into the hole cylinders (10) by air pressure. This pressure is obtained by a pear (13) incorporated in the handle brush hollow (2). This pear (13) can be operated either with your fingertips through holes access (14) in the handle (2), either by an articulated lever (15) (16) allowing to exercise a pressure on the pear, either by direct pressure on the pear which is left visible, leaving a large opening (17) in the hollow handle (2).

The operation of this pear is traditional, it has two non-return valves, one for the air (18), the other for the coloring product (19).
