Description

L'invention est relative à une brosse, en particulier une brosse pour appliquer un produit cosmétique sur les fibres kératiniques, notamment pour appliquer du mascara sur les cils ou une teinture sur les cheveux, ainsi qu'à un dispositif de maquillage comportant cette brosse, la brosse ayant un profil sensiblement plan-concave.The invention relates to a brush, in particular a brush for applying a product. cosmetic on keratin fibers, in particular for applying mascara to the eyelashes or a dye on the hair, as well as a makeup device comprising this brush, the brush having a substantially plano-concave profile.

Habituellement, une brosse pour l'application d'un produit cosmétique comprend le plus souvent une âme allongée formée par l'enroulement en hélice de deux branches d'un fil métallique, des poils implantés radialement dans cette âme et serrés entre ces branches enroulées. De telles brosses peuvent être de formes variées et comporter des découpes.Usually a brush for applying a cosmetic product most comprises often an elongated core formed by the helical winding of two branches of a wire metallic, hairs implanted radially in this core and clamped between these branches rolled up. Such brushes can be of various shapes and include cutouts.

Dans le cas où ces brosses sont utilisées pour appliquer un mascara sur les cils, de telles formes et de telles découpes sont prévus pour permettre l'obtention d'un maquillage plus ou moins chargé, un allongement et un recourbement plus ou moins important des cils.In the event that these brushes are used to apply mascara to the eyelashes, such shapes and such cuts are provided to allow obtaining a more or less loaded make-up, more or less elongation and bending important eyelashes.

On connait de l'art antérieur, par exemple par la demande de brevet FR-A-2715038, des brosses à mascara ayant une forme quelconque. dans lesquelles une encoche concave a été découpée, sur toute leur longueur. Les poils de l'encoche concave étant courts, ils sont peu essorés à la sortie du réservoir contenant le mascara, de telles brosses donnent un maquillage très chargé.We know from the prior art, for example by patent application FR-A-2715038, of mascara brushes of any shape. in which a concave notch has been cut along their entire length. The hairs of the concave notch being short, they are little wrung out of the tank containing the mascara, such brushes give a very charged makeup.

On connait également des brosses ayant la forme d'un fragment de tore, ces brosses étant obtenues par la torsion en arc de cercle de l'âme d'une brosse cylindrique. De telles brosses présentent une face convexe, une face concave et deux faces sensiblement planes. De telles brosses sont d'une manipulation peu aisée: en effet, si l'utilisateur fait tourner entre ses doigts la tige d'une telle brosse autour de son axe, pour appliquer un produit sur les cils par exemple, il doit en permanence rectifier la distance de la brosse aux cils. En outre, on a constaté qu'une telle brosse chargeait les cils en les lissant peu. Des brosses obtenues par la torsion en arc de cercle de l'âme d'une brosse cylindro-cônique présentent les mêmes inconvénients.We also know brushes having the shape of a torus fragment, these brushes being obtained by the torsion in an arc of a circle of the core of a cylindrical brush. Of such brushes have a convex face, a concave face and two faces substantially flat. Such brushes are not easy to handle: indeed, if the user rotates between his fingers the rod of such a brush around its axis, to apply a product on the eyelashes for example, it must constantly correct the distance from the eyelash brush. In addition, it has been found that such a brush charges the eyelashes by smoothing little. Brushes obtained by the torsion in an arc of a circle of the core of a brush cylindro-conical have the same disadvantages.

Bien que ces brosses de l'art antérieur donnent des résultats globalement satisfaisants, il est apparu souhaitable de disposer de brosses permettant une bonne prise en charge des cils par la brosse pour assurer un bon lissage du produit et une bonne séparation des cils tout en chargeant les cils en produit pour obtenir un maquillage sophistiqué. Although these prior art brushes give generally satisfactory results, it appeared desirable to have brushes allowing good support eyelashes by brush to ensure good smoothing of the product and good separation eyelashes while loading the eyelashes with product to obtain a sophisticated make-up.

L'invention a pour but également de fournir une brosse qui reste d'application simple et économique et d'une utilisation pratique.The invention also aims to provide a brush which remains simple to apply and economical and practical to use.

La demanderesse a découvert de façon inattendue de nouvelles brosses pour l'application d'un produit cosmétique, qui, lorsqu'elles sont employées pour appliquer un mascara sur les cils permettent d'obtenir un maquillage sophistiqué de haute qualité, c'est-à-dire chargé mais très allongé avec des cils très bien séparés, ces brosses étant par ailleurs d'une manipulation très facile.The Applicant unexpectedly discovered new brushes for applying a cosmetic product, which when used to apply a mascara on the eyelashes make it possible to obtain sophisticated high-quality make-up, that is to say loaded but very elongated with very well separated eyelashes, these brushes being otherwise very easy to handle.

L'invention a pour objet une brosse comprenant une tige droite définissant un axe principal, une âme flexible, comportant deux extrémités, solidaire par sa première extrémité de cette tige, des poils implantés radialement dans cette âme, l'extrémité des poils définissant la surface de la brosse, cette surface comportant une première face, l'intersection de tout plan passant par l'axe principal, appelé plan méridien, avec la surface de la brosse définissant deux courbes appelées lignes de crête ayant une certaine courbure, cette brosse étant caractérisée en ce que les lignes de crêtes sont concaves, et que la première face est sensiblement droite et parallèle à l'axe principal.The subject of the invention is a brush comprising a straight rod defining an axis main, a flexible core, having two ends, secured by its first end of this rod, hairs implanted radially in this core, the end of bristles defining the surface of the brush, this surface comprising a first face, the intersection of any plane passing through the main axis, called the meridian plane, with the brush surface defining two curves called ridge lines having a certain curvature, this brush being characterized in that the ridges are concave, and that the first face is substantially straight and parallel to the main axis.

Par lignes de crête concaves, on entend que leur concavité est tournée vers l'extérieur de la brosse.By concave ridge lines is meant that their concavity faces outward of the brush.

La courbure d'une ligne de crête est l'inverse : 1/r, de son rayon de courbure r.The curvature of a crest line is the inverse: 1 / r, of its radius of curvature r.

En chaque point de l'âme l'intersection de la surface de la brosse avec tout plan perpendiculaire à l'âme définit une section de la brosse: Préférentiellement, l'âme est centrale par rapport à chaque section de la brosse.At each point of the soul the intersection of the surface of the brush with any plane perpendicular to the core defines a section of the brush: Preferably, the core is central to each section of the brush.

Les faces sont des portions longitudinales de la surface de la brosse.The faces are longitudinal portions of the surface of the brush.

De préférence, la surface de la brosse comporte au moins une seconde face, dite face de courbure maximum, caractérisée en ce que la courbure des lignes de crête passe par un maximum au niveau de cette seconde face.Preferably, the surface of the brush has at least one second face, called the face of maximum curvature, characterized in that the curvature of the crest lines passes through a maximum at the level of this second face.

Préférentiellement, la surface de la brosse comporte une seule face droite. Preferably, the surface of the brush has only one straight face.

Préférentiellement, la courbure des lignes de crête passe par un seul maximum.Preferably, the curvature of the ridge lines passes through a single maximum.

Préférentiellement la courbure des lignes de crête croít de façon continue depuis la face droite jusqu'à la face de courbure maximum.Preferably the curvature of the ridge lines increases continuously from the face straight to the face of maximum curvature.

Préférentiellement les faces de courbure maximum et droite sont diamétralement opposées par rapport à l'âme.Preferably the faces of maximum and straight curvature are diametrically opposite to the soul.

De préférence, les poils d'une même section sont tous de même longueur.Preferably, the bristles of the same section are all of the same length.

L'invention a également pour objet un procédé de fabrication d'une brosse selon l'invention, caractérisé en ce que :

  • a) on prend une brosse de départ comportant une tige droite définissant un axe principal, une âme flexible, comportant une première et une deuxième extrémité, la première extrémité étant solidaire de cette tige, l'âme étant droite et dans l'alignement de la tige, des poils étant implantés radialement dans cette âme, l'extrémité des poils définissant la surface de la brosse de départ, ladite surface étant de forme globalement concave, comme par exemple une brosse ayant la forme d'un diabolo ou d'une cacahuète, l'intersection de tout plan méridien passant par l'axe principal, avec la surface de la brosse de départ définissant deux méridiennes, concaves, ayant une courbure déterminée,
  • b) une première étape consiste à imprimer à l'âme une torsion dans un plan méridien, ladite torsion étant une courbure sensiblement égale à la courbure d'une des deux lignes de crêtes de ce plan, la surface présentant alors une première face sensiblement droite et parallèle à l'axe pricipal.
    • The subject of the invention is also a method of manufacturing a brush according to the invention, characterized in that:
  • a) we take a starting brush comprising a straight rod defining a main axis, a flexible core, comprising a first and a second end, the first end being integral with this rod, the core being straight and in alignment with the rod, bristles being implanted radially in this core, the end of the bristles defining the surface of the starting brush, said surface being of generally concave shape, such as for example a brush having the shape of a diabolo or a peanut , the intersection of any meridian plane passing through the main axis, with the surface of the starting brush defining two meridians, concave, having a determined curvature,
  • b) a first step consists in imparting to the core a twist in a meridian plane, said twist being a curvature substantially equal to the curvature of one of the two ridges of this plane, the surface then having a first substantially straight face and parallel to the main axis.

    • En chaque point de l'âme, l'intersection de la surface de la brosse de départ avec tout plan perpendiculaire à l'âme définit une section de la brosse de départ. De préférence, la brosse de départ est choisie de telle sorte que l'âme soit centrale par rapport à chaque section de la brosse de départ.At each point of the soul, the intersection of the surface of the starting brush with everything plane perpendicular to the core defines a section of the starting brush. Preferably, the starting brush is chosen so that the core is central to each section of the starting brush.

    Ainsi la surface de la brosse de départ se trouve modifiée: une méridienne se trouve transformée en une ligne de crête sensiblement droite, la courbure de la seconde méridienne appartenant au même plan méridien étant sensiblement accentuée. L'âme reste centrale par rapport à chaque section de la brosse, toutefois ces sections ne sont plus parallèles. Thus the surface of the starting brush is modified: a meridian is transformed into a substantially straight ridge line, the curvature of the second meridian belonging to the same meridian plane being significantly accentuated. Blade remains central to each section of the brush, however these sections are not more parallel.

    De préférence, dans une seconde étape, on imprime une torsion à l'extrémité de l'âme qui est solidaire de la tige afin d'aligner la seconde extrémité de l'âme sur l'axe principal. Ainsi, la brosse selon l'invention peut être utilisée avec un réservoir de mascara muni d'un essoreur de conception usuelle.Preferably, in a second step, we print a twist at the end of the core which is integral with the rod in order to align the second end of the core on the main axis. Thus, the brush according to the invention can be used with a mascara tank provided of a wringer of usual design.

    De préférence, l'un des plans méridiens de la surface de la brosse de départ est un plan de symétrie de la brosse de départ. Eventuellement, la brosse de départ comprend un plan de symétrie perpendiculaire à l'axe de l'âme.Preferably, one of the meridian planes of the surface of the starting brush is a plane of symmetry of the starting brush. Optionally, the starting brush includes a plane of symmetry perpendicular to the axis of the core.

    Encore plus préférentiellement la surface de cette brosse de départ est de révolution.Even more preferably, the surface of this starting brush is of revolution.

    Avantageusement, chaque section de la brosse de départ est convexe.Advantageously, each section of the starting brush is convex.

    Cette brosse est tout à fait appropriée au maquillage des cils, aussi l'invention a également pour objet un dispositif de maquillage comprenant un réservoir à mascara et un organe d'application de mascara, cet organe d'application étant une brosse selon l'invention.This brush is entirely suitable for making up the eyelashes, so the invention has also relates to a makeup device comprising a mascara reservoir and a mascara application member, this application member being a brush according to the invention.

    La brosse selon l'invention présente un profil évolutif continu plan-concave par rapport à son axe principal: lorsque la brosse effectue une révolution autour de son axe principal, par exemple lorsque l'utilisateur fait tourner la tige de la brosse selon l'invention entre ses doigts, elle évolue d'une face sensiblement plane qui entoure la ligne de crête droite parallèle à l'axe principal vers une face concave à rayon de courbure croissant pour atteindre une courbure maximum puis décroítre et revenir à une face plane.The brush according to the invention has a continuous plano-concave evolving profile. compared to its main axis: when the brush makes a revolution around its main axis, for example when the user turns the brush rod according to the invention between his fingers, it evolves from a substantially flat face which surrounds the straight ridge line parallel to the main axis towards a concave face with increasing radius of curvature for reach a maximum curvature then decrease and return to a flat face.

    Le profil sensiblement plan se trouve de préférence diamétralement opposé à la concavité de la brosse par rapport à l'âme. Chaque section étant perpendiculaire à l'âme en tout point de celle-ci, les poils de la brosse présentent une densité moins élevée par rapport au reste de la brosse le long de ce profil plan. En outre, ces poils divergent. De préférence, la face diamétralement opposée à la face droite par rapport à l'âme, est celle qui présente la courbure la plus importante. Ainsi, cette face a une densité de poils beaucoup plus importante et ces poils convergent. The substantially planar profile is preferably diametrically opposite the concavity of the brush with respect to the core. Each section being perpendicular to the core at any point of it, the bristles of the brush have a lower density by relative to the rest of the brush along this plane profile. In addition, these hairs diverge. Of preferably, the face diametrically opposite the straight face with respect to the core, is that which has the greatest curvature. So this face has a density of hairs much larger and these hairs converge.

    Lorsque l'utilisateur utilise cette brosse pour appliquer un produit de maquillage sur les cils, il extrait la brosse du réservoir de produit, celle-ci traverse un essoreur. Lorsque les poils d'une même section sont tous de même longueur, ils sont tous essorés. Toutefois, la face comportant un profil sensiblement plan est mieux essorée du fait que les poils divergent et sont peu denses. La face présentant la courbure la plus importante est en revanche très peu essorée car la répartition des poils est très dense. L'utilisateur place la brosse contre les cils et la fait tourner entre ses doigts : celle ci lisse recourbe et sépare les cils par son profil plan, puis elle le charge en produit par le reste de sa surface.When the user uses this brush to apply makeup to the eyelashes, he extracts the brush from the product reservoir, which passes through a wringer. When the hairs of the same section are all the same length, they are all wrung out. However, the face having a substantially flat profile is better wrung out because the hairs diverge and are sparse. The side with the greatest curvature is however very little wrung because the distribution of hair is very dense. The user places the brush against the eyelashes and rotate it between his fingers: this smooth curls and separates the eyelashes by its flat profile, then it loads it with product by the rest of its surface.

    Le maquillage obtenu est chargé, allongé, recourbé.The makeup obtained is loaded, elongated, curled.

    En outre, les poils des brosses selon l'invention peuvent être de toute espèce : poils de longueurs différentes, de diamètres différents ou de section différentes et de matières différentes, poils à extrémités effilées, en forme de fourchette ou de tête d'épingle, ou avoir subi toute sorte de traitement connu de l'homme du métier.In addition, the bristles of the brushes according to the invention can be of any kind: bristles different lengths, different diameters or different cross-sections and materials different, hairs with tapered ends, fork or pin head shape, or have undergone any kind of treatment known to those skilled in the art.

    On peut également prévoir que la brosse selon l'invention comporte une alternance de rangées de poils courts et de poils longs, les poils longs étant seuls pris en compte pour définir la surface de la brosse. Une telle variante de l'invention permet d'accentuer le chargement du cil en produit par la brosse de l'invention.It is also possible to provide that the brush according to the invention comprises an alternation of rows of short hairs and long hairs, only long hairs being taken into account for define the surface of the brush. Such a variant of the invention makes it possible to accentuate the loading the eyelash with product by the brush of the invention.

    L'enroulement en hélice des deux branches du fil métallique formant l'âme peut être prévu avec un pas à droite, comme cela est habituellement prévu dans la fabrication de brosses de maquillage, ou un pas à gauche, comme cela est enseigné par la demande de brevet FR-A-2701198. Pour fabriquer une brosse à pas à gauche, les branches de l'âme sont torsadées en tournant à gauche pour former des spires qui tournent en sens d'horloge autour de l'âme quand on progresse de la tige vers l'extrémité de la brosse.The helical winding of the two branches of the metallic wire forming the core can be planned with a step to the right, as is usually expected in the manufacture of makeup brushes, or step left, as taught by demand FR-A-2701198. To make a left-hand brush, the branches of the soul is twisted by turning to the left to form turns which turn in direction of clock around the core when one progresses from the rod towards the end of the brush.

    La brosse avec un pas à gauche est préférée pour la réalisation de brosses selon l'invention: en effet, cette caractéristique donne aux spires de poils une orientation permettant de mieux séparer les cils lors du maquillage.The brush with a step to the left is preferred for the realization of brushes according to the invention: in fact, this characteristic gives the hair turns an orientation allowing better separation of the eyelashes during makeup.

    L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après à propos d'exemples de réalisation décrits en référence aux dessins ci-annexés, mais qui ne sont nullement limitatifs.The invention consists, apart from the arrangements set out above, in a certain number of other provisions which will be more explicitly discussed below about of embodiments described with reference to the accompanying drawings, but which are not in no way limiting.

    La brosse 100 représentée sur les figures 1A et 1B comporte une tige droite 101 définissant un axe principal X-X. A l'extrémité 101.1 de cette tige 101 est fixée, par emmanchement à force, une âme 102 (que l'on a représenté sur cette figure bien qu'elle soit à l'intérieur de la brosse) allongée formée par l'enroulement en hélice de deux branches d'un fil métallique 103 qui a été replié en U avant que les branches ne soient torsadées. L'axe de l'âme 102 est confondu avec l'axe principal X-X. Des poils 104 sont implantés radialement entre les branches du fil 103. Lorsque les branches du fil 103 sont torsadées, les poils sont serrés et maintenus entre les spires en hélice de l'âme 102. Les extrémités des poils 104 définissent la surface de la brosse 105 : c'est une surface de révolution qui a la forme d'un diabolo et dont les extrémités sont constituées par deux sections droites le disque 106.a, de centre 108.a et le disque 106.b de centre 108.b. Chaque section 106 de la brosse 100 a la forme d'un disque, toutes les sections 106 sont parallèles entre elles. L'intersection de la surface 105 avec tout plan méridien de la brosse définit des méridiennes 107, toutes identiques, ayant le même rayon de courburer.The brush 100 shown in Figures 1A and 1B has a straight rod 101 defining a main axis X-X. At the end 101.1 of this rod 101 is fixed, by press fitting, a core 102 (which has been represented in this figure although it either inside the brush) elongated formed by the helical winding of two branches of a metallic wire 103 which has been folded in a U before the branches are twisted. The axis of the core 102 coincides with the main axis X-X. Hairs 104 are implanted radially between the branches of the wire 103. When the branches of the wire 103 are twisted, the bristles are clamped and held between the helical turns of the core 102. The ends of the bristles 104 define the surface of the brush 105: it is a surface of revolution which has the shape of a diabolo and whose ends are formed by two straight sections the disc 106.a, of center 108.a and the disc 106.b of center 108.b. Each section 106 of the brush 100 has the shape of a disc, all the sections 106 are parallel to each other. The intersection of the surface 105 with any meridian plane of the brush defines meridians 107, all identical, having the same radius of curvature.

    On imprime à l'âme 102, à l'aide d'un outil approprié, par exemple en la pressant longitudinalement autour d'un cylindre métallique de rayon de courbure r, une première torsion dans un plan méridien, entre les sections 106.a et 106.b, de telle sorte qu'elle prenne la forme d'une des méridiennes 107, puis une seconde torsion, dans le même plan, entre l'extrémité 101.1 de la tige et le centre 108.a de la section d'extrémité de la brosse, de façon à aligner le centre 108.b de l'autre extrémité de la brosse sur l'axe principal X-X comme la première extrémité 108.a.The core 102 is printed, using an appropriate tool, for example by pressing it longitudinally around a metal cylinder with radius of curvature r, a first twist in a meridian plane, between sections 106.a and 106.b, so that it take the form of one of the meridians 107, then a second twist, in the same plane, between the end 101.1 of the rod and the center 108.a of the end section of the brush, so as to align the center 108.b of the other end of the brush with the axis main X-X as the first end 108.a.

    Par cette opération on obtient une brosse 200 selon l'invention représentée sur les figures 2A et 2B. Sur ces figures, les références affectées à des éléments analogues à ceux des figures 1A et 1B sont celles des figures 1A et 1B augmentées de 100.By this operation, a brush 200 is obtained according to the invention shown in the Figures 2A and 2B. In these figures, the references assigned to elements analogous to those of FIGS. 1A and 1B are those of FIGS. 1A and 1B increased by 100.

    La brosse des figures 2A et 2B se distingue de celle des figures 1A et 1B par le fait que l'âme 202 est courbe, avec un rayon de courbure sensiblement égal à r. Toutefois, ses extrémités 208.a et 208.b sont alignées sur l'axe principal X-X. L'intersection de la surface 205 de la brosse avec les plans passant par l'axe principal X-X définit des lignes de crête 207. La figure 2B est issue de la figure 2A par rotation d'un quart de tour autour de l'axe principal X-X. On remarque sur la figure 2A que les sections 206 convergent alors que les sections 106 de la brosse de la figure 1 sont parallèles. La brosse de la figure 2A comprend deux faces : une première face 207.1, droite, sensiblement parallèle à l'axe principal X-X, et une seconde face 207.2, courbe, diamétralement opposées par rapport à l'âme 202. Le passage d'une ligne de crête à une autre se fait de façon continue, avec une variation continue de la courbure depuis la courbure maximum de 207.2 à une ligne de crête sensiblement droite comme 207.1.The brush of FIGS. 2A and 2B differs from that of FIGS. 1A and 1B by the fact that the core 202 is curved, with a radius of curvature substantially equal to r. However, his ends 208.a and 208.b are aligned on the main axis X-X. The intersection of the surface 205 of the brush with the planes passing through the main axis X-X defines lines of crest 207. FIG. 2B is taken from FIG. 2A by rotation of a quarter turn around of the main axis X-X. Note in FIG. 2A that the sections 206 converge while the sections 106 of the brush of Figure 1 are parallel. The brush of the FIG. 2A comprises two faces: a first face 207.1, straight, substantially parallel to the main axis X-X, and a second face 207.2, curved, diametrically opposed by relative to the core 202. The passage from one ridge line to another is done in a way continuous, with a continuous variation of the curvature from the maximum curvature of 207.2 to a substantially straight ridge line like 207.1.

    Sur la figure 3, les références affectées à des éléments analogues à ceux des figures 1A et 1B sont celles des figures 1A et 1B augmentées de 200.
    La brosse représentée à la figure 3 se distingue de celle de la figure 1 par sa surface 305 qui a la forme d'une cacahuète. Chacune des sections 306 de la brosse a la forme d'un disque. Les méridiennes 307 sont de courbure principale concave variable, en outre, leurs extrémités 309 présentent une légère convexité.    In FIG. 3, the references assigned to elements similar to those of FIGS. 1A and 1B are those of FIGS. 1A and 1B increased by 200.
    The brush shown in Figure 3 differs from that of Figure 1 by its surface 305 which has the shape of a peanut. Each of the sections 306 of the brush has the shape of a disc. The meridians 307 have a variable concave main curvature, in addition, their ends 309 have a slight convexity.

    On imprime à l'âme 302, à l'aide d'un outil approprié, par exemple en la pressant longitudinalement autour d'un cylindre métallique de rayon de courbure r', une première torsion, dans le plan d'une méridienne 307.1, entre les sections 306.a et 306.b, de telle sorte qu'elle adopte la même courbure r' que cette méridienne 307.1, la torsion étant faite en sens opposé par rapport à cette méridienne; puis dans le même plan, une seconde torsion entre l'extrémité 301.1 de la tige et le centre 308.a de la section d'extrémité de la brosse, de façon à aligner le centre 308.b de l'autre extrémité de la brosse sur l'axe principal X-X comme la première extrémité 308.a.We print to the core 302, using an appropriate tool, for example by pressing it longitudinally around a metal cylinder with radius of curvature r ', a first torsion, in the plane of a meridian 307.1, between sections 306.a and 306.b, such so that it adopts the same curvature r 'as this meridian 307.1, the torsion being made in opposite direction with respect to this meridian; then in the same shot, a second twist between the end 301.1 of the rod and the center 308.a of the section end of the brush, so as to align the center 308.b of the other end of the brush on the main axis X-X like the first end 308.a.

    Par l'opération décrite ci-dessus on obtient une brosse 400 selon l'invention représentée sur les figures 4A et 4B. Sur ces figures, les références affectées à des éléments analogues à ceux de la figure 3 sont celles de la figure 3 augmentées de 100.By the operation described above, a brush 400 according to the invention shown is obtained. in Figures 4A and 4B. In these figures, the references assigned to elements analogous to those in FIG. 3 are those of FIG. 3 increased by 100.

    La brosse des figures 4A et 4B se distingue de celle de la figure 2 par le fait que les extrémités de la surface 405, autour des sections droites 406.a et 406.b sont arrondies. L'âme 402 est courbe, sa courbure r' est sensiblement égale à celle d'une des méridiennes 307.1 de la brosse de départ décrite à la figure 3. L'intersection de la surface 405 de la brosse avec les plans passant par l'axe principal X-X définit des lignes de crête. La figure 4B est issue de la figure 4A par rotation d'un quart de tour autour de l'axe principal X-X. On remarque sur la figure 4A que les sections 406, circulaires, convergent, alors que les sections 306 de la brosse de la figure 3 sont parallèles. La brosse de la figure 4A comprend deux faces: 407.1, droite, sensiblement parallèle à l'axe principal X-X, infléchie à ses extrémités 409.1 vers l'âme 402; 407.2, courbe, concave, avec une inflexion de la courbe vers l'âme 402 à ses extrémités 409.2 Les deux faces sont diamétralement opposées par rapport à l'âme 402. Le passage d'une ligne de crête à une autre se fait de façon continue, avec une variation continue de la courbure principale autour de l'axe principal X-X est continue.The brush of FIGS. 4A and 4B differs from that of FIG. 2 by the fact that the ends of the surface 405, around the straight sections 406.a and 406.b are rounded. The core 402 is curved, its curvature r 'is substantially equal to that of one of the Meridians 307.1 of the starting brush described in Figure 3. The intersection of the 405 surface of the brush with the planes passing through the main axis X-X defines lines crest. FIG. 4B is taken from FIG. 4A by rotation of a quarter turn around the main axis X-X. Note in FIG. 4A that the circular sections 406, converge, while the sections 306 of the brush of FIG. 3 are parallel. The brush of FIG. 4A comprises two faces: 407.1, straight, substantially parallel to the main axis X-X, bent at its ends 409.1 towards the core 402; 407.2, curve, concave, with an inflection of the curve towards the core 402 at its ends 409.2 Both faces are diametrically opposite with respect to the core 402. The passage of a line of ridge to another is done continuously, with a continuous variation in curvature main around the main axis X-X is continuous.

    Le dispositif pour le maquillage des yeux représenté sur la figure 5 comprend un réservoir cylindrique 520, qui comporte un goulot 524, fileté, surmonté d'un joint d'étanchéité 525 et qui est rempli d'un mascara 515. Le réservoir 520 comporte dans son goulot un essoreur 521, le maintien en position de l'essoreur dans le goulot étant assuré grâce à un bourrelet 526 qui coopère avec l'épaulement séparant le goulot du réservoir 520 proprement dit. L'essoreur 521 est constitué, de façon connue, en une matière souple et élastique. Un applicateur est destiné à coopérer avec le réservoir 520. Cet applicateur est constitué d'un moyen de préhension 523 qui supporte l'organe d'application 530, comprenant une tige 522 et un organe applicateur 501, identiques à ceux représentés sur les figures 2A et 2B. Le moyen de préhension 523 a la forme d'un capuchon et comporte un filetage 523a qui coopère avec le filetage 524a du goulot du réservoir. L'obturation étanche du réservoir 520 est obtenue en vissant le moyen de préhension 523 sur le goulot 524 du réservoir muni de son joint 525.The device for making up the eyes shown in FIG. 5 comprises a cylindrical tank 520, which has a neck 524, threaded, surmounted by a seal seal 525 and which is filled with a mascara 515. The reservoir 520 comprises in its neck of a wiper 521, maintaining the wiper in position in the neck being ensured thanks to a bead 526 which cooperates with the shoulder separating the neck from the reservoir 520 proper. The wiper 521 is made, in a known manner, of a material flexible and elastic. An applicator is intended to cooperate with the reservoir 520. This applicator consists of a gripping means 523 which supports the member 530, comprising a rod 522 and an applicator member 501, identical to those shown in Figures 2A and 2B. The gripping means 523 has the form of a cap and has a thread 523a which cooperates with the thread 524a of the neck of the tank. The sealed closure of the tank 520 is obtained by screwing the means of gripping 523 on the neck 524 of the tank provided with its seal 525.

    Lorsque l'on extrait l'organe d'application 530 du réservoir, l'organe applicateur, ayant la forme d'une brosse, chargé de mascara passe à travers l'essoreur 521. Celui-ci essore les poils des faces de forte courbure de façon beaucoup plus importante que les poils des faces planes.
    A l'application sur le cil, la brosse lisse recourbe et sépare le cil par son profil plan, puis elle le charge en produit par le reste de sa surface.    When the applicator member 530 is extracted from the reservoir, the applicator member, having the shape of a brush, charged with mascara passes through the wiper 521. The latter wring out the hairs from the faces of strong curvature much more importantly than the hairs on the flat faces.
    When applied to the eyelash, the smooth brush curls and separates the eyelash by its flat profile, then it loads it with product through the rest of its surface.

    Par rapport aux brosses globalement concaves connues de l'art antérieur et par rapport aux brosses de courbures variées, comme les brosses cylindriques recourbées (fragments de tore) connues de l'art antérieur, la brosse selon l'invention offre l'avantage de bien peigner le cil, ce qui se traduit par un meilleur étalement du produit, un effet d'allongement et de recourbement plus prononcé.Compared to the generally concave brushes known from the prior art and compared with brushes of various curvatures, such as curved cylindrical brushes (torus fragments) known from the prior art, the brush according to the invention offers the advantage comb the eyelash well, which results in better spreading of the product, an effect more pronounced elongation and bending.
