Abstract

Applicator consists of a handle (11) and a head (12) implanted with teeth or bristles. The head has three corners or projections (14 - 17), of which two (14, 16) lie opposite one another on a line lying perpendicular to the axis (X) of the handle. Another projection (15) is located opposite the handle and parallel to it, while none of the head's edges (18 - 21) are parallel to the handle's axis. The corners of the head are rounded, and the tips of the bristles or teeth lie on a concave surface.

Description

La présente invention a trait à un applicateur pour produit capillaire, notamment sous forme de mousse, de gel ou de crème. L'invention est tout particulièrement adaptée à l'application de produits de coloration.The present invention relates to an applicator for hair product, in particular in the form of foam, gel or cream. The invention is everything particularly suitable for the application of coloring products.

Une grande tendance actuelle, dans le domaine capillaire, est de créer dans la chevelure, des effets couleurs plus ou moins visibles, et plus ou moins subtils dont le but est, soit de maquiller les cheveux avec des couleurs vives, telles que le jaune, le vert, le bleu ou le rouge, soit de donner à la chevelure un particularisme qui soit le plus naturel possible.A major current trend in the hair sector is to create in the hair, more or less visible, and more or less subtle color effects whose purpose is either to make up the hair with bright colors, such whether yellow, green, blue or red, is to give the hair a particularity that is as natural as possible.

Or dans ce dernier cas, et jusqu'à maintenant, la coloration des cheveux restait affaire de professionnels, dès lors que l'on cherche des effets très subtils, d'aspect naturel.However in the latter case, and until now, the coloring of the hair remained business of professionals, when we look for very subtle effects, natural looking.

Le plus recherché de ces effets est celui qui consiste à obtenir dans la chevelure des zones (et non pas des mèches) qui soient plus claires ou plus foncées que le reste de la chevelure, pour nuancer le tout de façon très naturelle. Ces effets sont obtenus à partir de compositions de coloration, sous forme de gel, de pâte, de mousse ou de crème, que l'on dépose sur une brosse et que l'on applique sur la chevelure. Les compositions peuvent être conditionnées notamment dans des dispositifs mélangeurs, adaptés pour le mélange extemporané des différentes composantes qui les constituent (généralement, un colorant et un oxydant), dans un bol dans lequel on réalise manuellement le mélange, ou dans des récipients pressurisés. Or, les outils d'application proposés pour ce type de coloration "désuniformisée" donnent des résultats présentant un défaut majeur, tendant à baisser de façon très notable le niveau de naturel du rendu de couleurs. Ce défaut consiste en l'apparition de "barres" de couleur, situées vers la racine des cheveux, et qui proviennent de la forme même des applicateurs. Cette barre est le résultat du point de départ de l'application, quand celle-ci est réalisée avec un applicateur à "zones d'attaque" sensiblement rectilignes ou présentant un grand rayon de courbure. La zone d'attaque s'entend de la zone de départ de l'application.The most sought after of these effects is that of obtaining in the hair areas (not highlights) that are lighter or darker darker than the rest of the hair, to shade it all up very natural. These effects are obtained from coloring compositions, under form of gel, paste, foam or cream, which is deposited on a brush and that we apply to the hair. The compositions can be packaged in particular in mixing devices, suitable for extemporaneous mixture of the various components which constitute them (usually a dye and an oxidant), in a bowl in which we make manually the mixture, or in pressurized containers. The tools of application proposed for this type of "disuniformized" coloring give results showing a major defect, tending to drop very markedly the natural level of color rendering. This defect consists of the appearance of colored "bars", located towards the hairline, which come from the even trains applicators. This bar is the result of the starting point of the application, when it is carried out with an applicator with "attack zones" substantially straight or with a large radius of curvature. The area of attack means the starting area of the application.

Ce phénomène est illustré aux figures 1A et 1B, représentant l'application d'un produit de coloration capillaire sur la chevelure au moyen d'une brosse de forme allongée (en forme de ballon de rugby). A la figure 1A, le grand axe de la brosse est sensiblement perpendiculaire à l'axe du manche. A la figure 1B, le grand axe de la brosse est parallèle à l'axe du manche. Dans les deux cas, l'expérience montre que l'utilisatrice utilise toujours l'une des grandes faces 1 de la brosse comme zone d'attaque. Dans les deux cas, elle fait parcourir à la brosse un mouvement de haut en bas, en tirant la brosse perpendiculairement à son grand axe. En raison du fort rayon de courbure de cette face, l'application génère l'apparition d'une "barre" 2 (sous forme d'une ligne droite, ou d'une courbe à grand rayon de courbure) dont l'effet n'est pas du tout naturel, et donc perçu de manière très négative.This phenomenon is illustrated in FIGS. 1A and 1B, representing the application of a hair coloring product on the hair using a brush elongated shape (shaped like a rugby ball). In FIG. 1A, the major axis of the brush is substantially perpendicular to the axis of the handle. In Figure 1B, the major axis of the brush is parallel to the axis of the handle. In both cases, experience shows that the user always uses one of the large faces 1 of the brush as an attack zone. In both cases, it causes the brush up and down, pulling the brush perpendicularly to its major axis. Due to the large radius of curvature of this face, the application generates the appearance of a "bar" 2 (in the form of a straight line, or a curve with large radius of curvature) whose effect is not at all natural, and therefore perceived very negatively.

Il a été tenté de résoudre ce problème en utilisant une brosse de section circulaire. Toutefois, il apparaít que si l'on souhaite avoir une surface d'application suffisamment grande, alors on est obligé d'avoir un rayon de courbure relativement important, générant à l'application, certes dans une moindre mesure qu'une brosse ovoïde, une "barre" perçue de manière négative par l'utilisatrice.An attempt has been made to solve this problem by using a section brush. circular. However, it appears that if one wishes to have a surface of sufficiently large application, then we are obliged to have a radius of relatively large curvature, generating on application, certainly in a lesser measure than an ovoid brush, a "bar" perceived negatively by the user.

Aussi, est-ce un des objets de l'invention que de réaliser un applicateur de produit capillaire ne présentant pas les inconvénients des dispositifs discutés ci-avant.It is therefore one of the objects of the invention to provide an applicator for hair product not having the drawbacks of the devices discussed above.

C'est en particulier un objet de l'invention que de fournir une brosse ne présentant pas de zone d'attaque droite ou à fort rayon de courbure. It is in particular an object of the invention to provide a brush which does not with no straight attack zone or with a large radius of curvature.

C'est un autre objet de l'invention que de réaliser un kit d'application d'un produit capillaire, incorporant un applicateur selon la présente invention.It is another object of the invention to produce an application kit for a hair product, incorporating an applicator according to the present invention.

D'autres objets de l'invention apparaítront de manière détaillée dans la description qui suit.Other objects of the invention will appear in detail in the description which follows.

Selon l'invention, ces objets sont atteints au moyen d'un applicateur de produit capillaire, notamment sous forme de mousse, de pâte, de gel ou de crème, comprenant un manche dont une extrémité est solidaire d'une brosse constituée d'un ensemble de dents ou poils implantés sur un support, la section de la brosse parallèlement à un plan du support présentant au moins trois coins ou excroissances dont deux sont orientés à l'opposé l'un de l'autre, sensiblement perpendiculairement à un axe du manche, le troisième étant orienté à l'opposé du manche, sensiblement parallèlement audit axe, ladite section ne comportant pas de bord sensiblement parallèle à l'axe du manche.According to the invention, these objects are achieved by means of a product applicator capillary, in particular in the form of foam, paste, gel or cream, comprising a handle, one end of which is integral with a brush consisting of a set of teeth or bristles implanted on a support, the section of the brush parallel to a plane of the support having at least three corners or outgrowths, two of which are oriented opposite each other, substantially perpendicular to an axis of the handle, the third being oriented opposite the handle, substantially parallel to said axis, said section having no edge substantially parallel to the axis of the handle.

Ainsi, quelque soit l'orientation du manche par rapport à la chevelure, la zone d'attaque est toujours constituée d'une zone anguleuse ou à faible rayon de courbure, ce qui évite le phénomène de "barre" discuté précédemment. En outre, elle est utilisable de la même manière par un gaucher ou par un droitier. Une telle configuration permet en outre de conserver une surface d'application suffisamment grande pour permettre une application dans des conditions de rapidité et d'efficacité acceptables.Thus, whatever the orientation of the handle relative to the hair, the area always consists of an angular area or a small radius of curvature, which avoids the "bar" phenomenon discussed above. In in addition, it can be used in the same way by a left-handed or a right-handed person. Such a configuration also makes it possible to maintain an application surface. large enough to allow application under conditions of acceptable speed and efficiency.

Avantageusement, les deux coins ou excroissances orientés à l'opposé l'un de l'autre sont alignés sensiblement selon un même axe perpendiculaire à l'axe du manche, le troisième étant disposé sensiblement sur l'axe du manche. De manière avantageuse, on réalise ainsi une brosse parfaitement symétrique, qui présente les mêmes caractéristiques d'application lorsqu'elle est utilisée par un gaucher ou par un droitier. Advantageously, the two corners or protrusions oriented opposite one of the other are aligned substantially along the same axis perpendicular to the axis of the handle, the third being arranged substantially on the axis of the handle. Of advantageously, a perfectly symmetrical brush is thus produced, which has the same application characteristics when used by a left or right handed.

Avantageusement encore, l'applicateur comprend un quatrième coin ou excroissance, situé à l'opposé du troisième, sensiblement dans l'axe du manche, ladite section ne comportant pas de bord sensiblement perpendiculaire à l'axe du manche. On augmente ainsi encore la surface efficace d'application, l'application étant toujours exempte de "barres" telles qu'évoquées précédemment.Advantageously also, the applicator comprises a fourth corner or protrusion, located opposite the third, substantially in the axis of the handle, said section not having an edge substantially perpendicular to the axis of the handle. This further increases the surface effective application, the application being always free of "bars" such that mentioned above.

Selon un mode de réalisation préférentiel, lesdits coins ou excroissances sont séparés par des portions de courbe concaves.According to a preferred embodiment, said corners or protrusions are separated by concave curve portions.

Le support peut lui même être constitué d'une surface concave. De façon avantageuse, la surface définie par les extrémités libres des poils ou dents est concave, la concavité de ladite surface étant orientée à l'opposé de la concavité du support.The support can itself consist of a concave surface. In a way advantageous, the surface defined by the free ends of the bristles or teeth is concave, the concavity of said surface being oriented opposite the concavity of the support.

Selon un mode de réalisation préféré, les coins ou excroissances sont de forme arrondie et présentent un rayon de courbure compris entre 1 mm et 15 mm, et de préférence entre 2 mm et 10 mm. De manière plus générale, le rayon de courbure de l'arrondi formé par les coins est au moins égal au rayon du cercle circonscrit par une dent ou par une touffe de poils. Quant à la limite supérieure, dans le cas d'une brosse dont la section est circonscrite par un cercle, elle est strictement inférieure au rayon dudit cercle. Cette caractéristique est nécessaire lorsque l'on souhaite un applicateur de surface suffisante, du type à excroissances reliées par des bords concaves, ce qui correspond à une configuration préférée de l'applicateur selon l'invention.According to a preferred embodiment, the corners or protuberances are of shape rounded and have a radius of curvature between 1 mm and 15 mm, and preferably between 2 mm and 10 mm. More generally, the radius of curvature of the rounding formed by the corners is at least equal to the radius of the circle circumscribed by a tooth or by a tuft of hairs. As for the upper limit, in the case of a brush whose section is circumscribed by a circle, it is strictly less than the radius of said circle. This characteristic is necessary when you want an applicator with sufficient surface, of the type to growths connected by concave edges, which corresponds to a preferred configuration of the applicator according to the invention.

Un tel applicateur peut être obtenu de moulage d'un matériau thermoplastique, notamment un polypropylène ou un polyéthylène. Le fait de pouvoir utiliser ces techniques industrielles de moulage, permet la réalisation d'un applicateur à très faible coût de revient. Such an applicator can be obtained by molding a thermoplastic material, in particular polypropylene or polyethylene. Being able to use these industrial molding techniques, allows the realization of an applicator very low cost.

Selon un autre aspect de l'invention, on réalise également un kit d'application d'un produit capillaire, notamment d'un produit de coloration capillaire, comprenant :

  • a) un dispositif pour le conditionnement dudit produit ; et
  • b) un applicateur selon l'invention.
    • According to another aspect of the invention, a kit for applying a hair product, in particular a hair coloring product, comprising:

  • b) an applicator according to the invention.

    • Avantageusement, le dispositif de conditionnement est constitué d'un dispositif mélangeur, d'un bol, ou d'un récipient pressurisé.Advantageously, the packaging device consists of a device mixer, bowl, or pressurized container.

    L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

    • la figure 5 illustre un mode de réalisation d'un kit d'application selon l'invention.
    The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
    • FIGS. 1A and 1B schematically illustrate one of the problems associated with the use of conventional application devices;
    • Figures 2A-2C illustrate a preferred embodiment of an applicator according to the invention;
    • Figures 3A-3B illustrate the application of a hair composition by means of an applicator according to Figures 2A-2C;

    L'applicateur 10 illustré aux figures 2A-2C comprend un manche 11 dont une extrémité est solidaire d'une brosse 12 constituée d'un support 30, sur lequel sont implantées, perpendiculairement au support 30, une pluralité de dents 13. A la place des dents, pourraient être utilisés des poils arrangés notamment sous forme de touffes. Le profil du manche de l'applicateur est choisi de manière à permettre la meilleure ergonomie, en vue d'optimiser l'application. Comme il apparaít aux figures 2A et 2C ainsi qu'à la figure 5, le manche est solidaire de la brosse 12 au niveau d'une zone de jonction 31 située sur la face du support 30 opposée à celle portant les dents. L'applicateur 10 est obtenu de moulage d'un matériau thermoplastique, tel qu'un polyéthylène ou un polypropylène.The applicator 10 illustrated in FIGS. 2A-2C comprises a handle 11, one of which end is integral with a brush 12 consisting of a support 30, on which a plurality of teeth 13 are implanted, perpendicular to the support 30. Instead of the teeth, hairs arranged in particular could be used in the form of tufts. The profile of the applicator handle is chosen from so as to allow the best ergonomics, in order to optimize the application. As it appears in Figures 2A and 2C as well as in Figure 5, the handle is integral with the brush 12 at a junction zone 31 located on the face of the support 30 opposite to that carrying the teeth. Applicator 10 is obtained from molding of a thermoplastic material, such as polyethylene or polypropylene.

    Le support 30 forme sensiblement un losange comportant 4 coins 14, 15, 16, 17. Deux des coins, 14, 16 sont orientés à l'opposé l'un de l'autre, et alignés selon un axe perpendiculaire à l'axe X du manche 11. Les deux autres coins 15, 17 sont également orientés à l'opposé l'un de l'autre et disposés sur l'axe X du manche. Les coins 14-17 sont de forme arrondie. Le rayon de courbure formé par les coins 14-17 est de l'ordre de 5 mm. Les bords du support 18, 19, 20, 21 reliant deux à deux les coins, sont de forme légèrement concaves, de manière à conférer encore plus de naturel à l'application, en réalisant une zone d'attaque sans aucune portion rectiligne.The support 30 substantially forms a rhombus comprising 4 corners 14, 15, 16, 17. Two of the corners, 14, 16 are oriented opposite each other, and aligned along an axis perpendicular to the axis X of the handle 11. The other two corners 15, 17 are also oriented opposite one another and arranged on the X axis of the handle. The corners 14-17 are rounded. The radius of curvature formed by the corners 14-17 is of the order of 5 mm. The edges of the support 18, 19, 20, 21 connecting the corners in pairs, are slightly concave in shape, so as to give the application even more naturalness, by creating an area of attack without any straight portion.

    Comme il apparaít aux figures 2B et 2C, illustrant des vues en coupe selon les deux axes du support 30, l'un passant par les coins 14 et 16, l'autre passant par les coins 15 et 17, le support 30 est de forme légèrement concave, avec sa concavité tournée vers les dents 13. Cette configuration permet d'appliquer de manière plus complète le produit déposé sur la brosse. En outre, la surface délimitée par l'extrémité libre des dents 13, est de forme également concave, avec sa concavité tournée vers le support 30. Cette caractéristique permet de mieux coller au profil convexe du crâne, et permet en outre de pouvoir déposer plus de produit sur la brosse.As it appears in Figures 2B and 2C, illustrating sectional views along the lines two axes of the support 30, one passing through the corners 14 and 16, the other passing by the corners 15 and 17, the support 30 is of slightly concave shape, with its concavity turned towards the teeth 13. This configuration makes it possible to apply more completely the product deposited on the brush. In addition, the surface delimited by the free end of the teeth 13, is also concave in shape, with its concavity facing the support 30. This characteristic makes it possible to better stick to the convex profile of the skull, and also allows you to deposit more product on the brush.

    L'utilisation de la brosse des figures 2A-2C est illustrée aux figures 3A et 3B. Le produit est un produit de coloration sous forme d'une crème ou d'une pâte, préparée dans un bol ou dans un dispositif mélangeur automatique. Le produit est déposé sur la face du support 30 portant les dents 13. A la figure 3A, l'utilisatrice dépose le produit sur les cheveux, depuis la racine vers les extrémités, par un mouvement de haut en bas (flèche F), en tenant le manche de façon sensiblement horizontale. La zone d'attaque est constituée du coin 16, et des deux bords 19, 20 attenants à ce coin. En raison de la forme de cet applicateur, la zone d'attaque est de largeur variant progressivement, avant d'atteindre la largeur maximale d'application délimitée par les deux coins 15 et 17. A la différence de l'application offerte par le dispositif discuté aux figures 1A et 1B, le départ de l'application du produit est progressif, en raison du profil à très faible rayon de courbure de la zone d'attaque, et de l'orientation sensiblement à 45° des bords 19, 20. Le résultat à l'application est remarquable par le naturel qui le caractérise.The use of the brush of Figures 2A-2C is illustrated in Figures 3A and 3B. The product is a coloring product in the form of a cream or a paste, prepared in a bowl or in an automatic mixing device. The product is deposited on the face of the support 30 carrying the teeth 13. In FIG. 3A, the user deposits the product on the hair, from the root to the ends, by a movement from top to bottom (arrow F), holding the handle substantially horizontally. The attack zone consists of the corner 16, and the two edges 19, 20 adjoining this corner. Due to the shape of this applicator, the attack zone is gradually varying in width, before to reach the maximum application width delimited by the two corners 15 and 17. Unlike the application offered by the device discussed in Figures 1A and 1B, the start of the application of the product is progressive, due to the profile to very small radius of curvature of the attack zone, and of the orientation substantially at 45 ° from the edges 19, 20. The result on application is remarkable by the naturalness that characterizes it.

    A la figure 3B, l'utilisatrice dépose le produit sur les cheveux, depuis la racine vers les extrémités, par un mouvement de haut en bas (flèche F), en tenant le manche de façon sensiblement verticale. La zone d'attaque est constituée du coin 15, et des deux bords 18, 19 attenants à ce coin. Le résultat est identique à celui obtenu avec le mode d'application de la figure 3A. Bien que non représenté, le résultat serait similaire en appliquant le produit par un mouvement d'avant en arrière sur la chevelure, les coins 14 ou 16 formant alors les zones d'attaque de l'application. Il est à noter qu'en raison de la forme symétrique de l'applicateur, les caractéristiques d'application sont identiques, que la brosse soit utilisée par un gaucher ou par un droitier.In FIG. 3B, the user deposits the product on the hair, from the root towards the ends, by a movement from top to bottom (arrow F), holding the handle substantially vertical. The attack zone consists of corner 15, and the two edges 18, 19 adjoining this corner. The result is identical to that obtained with the mode of application of FIG. 3A. Although not represented, the result would be similar by applying the product by a back and forth movement on the hair, the corners 14 or 16 forming then the attack areas of the application. It should be noted that due to the shape symmetrical of the applicator, the application characteristics are identical, whether the brush is used by a left-handed or a right-handed person.

    Selon la variante illustrée à la figure 4, le support 30 forme sensiblement un trèfle à trois feuilles. Selon ce mode de réalisation, le support 12 présente trois excroissances ou avancées 14, 15, 16, dont deux 14, 16 sont alignées selon un axe perpendiculaire à l'axe X du manche 11. La troisième 15 est située sur l'axe X, à l'opposé du manche 11. Les excroissances 14, 15, 16 sont reliées par des bords fortement concaves 18, 19. En termes de résultats à l'application, ils sont du même ordre que ceux obtenus avec l'applicateur des figures 2A-2C. Toutefois, la surface d'application est légèrement inférieure à celle de l'applicateur des figures 2A-2C.According to the variant illustrated in Figure 4, the support 30 substantially forms a three leaf clover. According to this embodiment, the support 12 has three protuberances or projections 14, 15, 16, two of which 14, 16 are aligned in a axis perpendicular to the X axis of the handle 11. The third 15 is located on the X axis, opposite the handle 11. The protuberances 14, 15, 16 are connected by strongly concave edges 18, 19. In terms of results to the application, they are of the same order as those obtained with the applicator of the Figures 2A-2C. However, the application surface is slightly less than that of the applicator of FIGS. 2A-2C.

    La figure 5 représente un kit d'application constitué d'un applicateur 10 du type de celui décrit en référence aux figures 2A-2C, en combinaison avec un dispositif de conditionnement, sous forme d'un récipient pressurisé 40, destiné à délivrer une mousse à appliquer sur les cheveux, au moyen de l'applicateur 10. Alternativement, le dispositif de conditionnement peut être constitué d'un bol, dans lequel serait réalisée manuellement la préparation de la composition à appliquer (typiquement par mélange d'un colorant et d'un oxydant) ou d'un dispositif mélangeur apte à réaliser de manière automatique le mélange des constituants entrant dans la composition de coloration. De tels dispositifs mélangeurs ont fait l'objet de nombreuses descriptions dans la littérature brevet et, par conséquent, ne nécessitent aucune description supplémentaire.FIG. 5 represents an application kit consisting of an applicator 10 of the type of that described with reference to FIGS. 2A-2C, in combination with a packaging device, in the form of a pressurized container 40, intended to deliver a foam to be applied to the hair, by means of the applicator 10. Alternatively, the packaging device may consist of a bowl, in which the preparation of the composition would be carried out manually to be applied (typically by mixing a dye and an oxidant) or a mixing device capable of automatically mixing the constituents entering into the coloring composition. Such devices mixers have been the subject of numerous descriptions in the patent literature and therefore do not require further description.

    Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. It is obvious that variants may exist there. be made without departing from the spirit of the invention as claimed below.
