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 une âme courbe.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 curved core.

Habituellement, une brosse pour l'application d'un produit cosmétique comprend une âme allongée formée par l'enroulement en hélice de deux branches d'un fil métallique, qui a été replié en U avant que les branches ne soient torsadées, 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 comprises a elongated core formed by the helical winding of two branches of a metal wire, which was folded into a U before the branches were twisted, hairs implanted radially in this core and clamped between these coiled branches. 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 prévues 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 connaít 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. Il est difficile avec ces brosses, de maquiller le coin de l'oeil sans bavures sur la paupières et l'aile du nez. 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 know brushes having the shape of a torus fragment, these brushes being obtained by the torsional arc of the core of a cylindrical brush. Such brushes have a convex face, a concave face and two substantially flat. Such brushes are not very easy to handle: in fact, if the user does turn the rod of such a brush between its fingers around its axis, to apply a product on the eyelashes for example, it must constantly correct the distance of the brush eyelashes. It is difficult with these brushes, to make up the corner of the eye without burrs on the eyelids and the wing of the nose. In addition, it has been found that such a brush charges the eyelashes. by smoothing them little. Brushes obtained by the torsion in an arc of a circle of the soul of a cylindro-conical brush have the same disadvantages.

Il est apparu donc 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. L'invention a pour but également de fournir une brosse qui reste d'application simple et économique et d'une utilisation pratique.It therefore appeared desirable to have brushes allowing good grip. load of the eyelashes by the brush to ensure a good smoothing of the product and a good separation of eyelashes. The invention also aims to provide a brush which remains simple and economical to apply 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 très recourbé, très allongé avec un produit réparti sur toute la longueur du cil. Ces brosses sont par ailleurs d'une manipulation très facile et permettent de maquiller facilement le coin de l'oeil.The Applicant unexpectedly discovered new brushes for applying a cosmetic product, which when used to apply a mascara on the eyelashes makes it possible to obtain a very curved, very elongated makeup with a product distributed over the entire length of the eyelash. These brushes are also of a very easy handling and make it easy to make up the corner of the eye.

L'invention a pour objet une brosse comprenant une tige droite définissant un axe (X-X) principal ; une âme flexible, définissant la longueur de la brosse, cette âme comportant une première et une seconde extrémité, la première extrémité étant solidaire de la tige ; des poils implantés radialement dans cette âme, l'extrémité des poils définissant la surface enveloppe de la brosse, cette surface enveloppe présentant une première et une seconde extrémités, caractérisée en ce que l'âme décrit une courbe (C) dans un plan de courbure (P) et que la surface enveloppe de la brosse présente sur au moins une partie de sa longueur, une section transversale de forme allongée selon un axe de plus grande longueur (Z-Z) perpendiculaire au plan de courbure (P). The subject of the invention is a brush comprising a straight rod defining an axis (X-X) main ; a flexible core, defining the length of the brush, this core comprising first and second ends, the first end being integral with the rod; hairs implanted radially in this core, the end of the hairs defining the envelope surface of the brush, this envelope surface having a first and a second ends, characterized in that the core describes a curve (C) in a plane of curvature (P) and that the envelope surface of the brush has on at least part of its length, a cross section of elongated shape along a larger axis length (Z-Z) perpendicular to the plane of curvature (P).

On entend par section transversale de la surface enveloppe une section de la surface enveloppe suivant un plan perpendiculaire à l'âme.The cross section of the envelope surface is understood to mean a section of the surface envelope in a plane perpendicular to the core.

Préférentiellement, la courbe (C) est sensiblement circulaire. La partie de la brosse se trouvant dans la concavité de la courbe (C) forme un creux. La partie de la brosse se trouvant du côté opposé forme le dos de la brosse. Les section transversales de la surface enveloppe de la brosse étant allongées, suivant l'axe de plus grande longueur, dans le sens perpendiculaire au plan (P) de torsion de l'âme, la brosse selon l'invention présente deux faces larges et applaties, l'une dans le creux de la brosse, l'autre dans le dos de la brosse. La face située dans le creux de la brosse est très proche par sa forme du contour des cils. En outre, elle comporte des poils courts et donc peu souples. Elle peut donc prendre en charge les cils sur toute la largeur de la paupière, les charger en produit, les allonger et les recourber. La distance entre les deux faces étant plus petite que la largeur de la brosse, celle-ci peut se glisser facilement dans le coin de l'oeil pour maquiller les cils, sans bavures autour du coin de l'oeil. Les côtés de la brosse, qui comportent des poils plus longs, et donc plus souples, que les faces, mais qui sont moins larges, permettent un peignage et une séparation des cils très efficaces. Le dos de la brosse, tout comme le creux, permet d'étaler le produit de maquillage ou de soin en prenant en charge le cil sur une grande partie de la longueur du cil. Ce dos étant bombé, il favorise le recourbement du cil.Preferably, the curve (C) is substantially circular. The part of the brush is located in the concavity of the curve (C) forms a hollow. The part of the brush is lying on the opposite side forms the back of the brush. The cross sections of the envelope surface of the brush being elongated, along the axis of greatest length, in the direction perpendicular to the plane (P) of torsion of the core, the brush according to the invention has two wide flat surfaces, one in the hollow of the brush, the other in the back of the brush. The face located in the hollow of the brush is very close by its shape eyelash contour. In addition, it has short bristles and therefore not very flexible. She can therefore take care of the eyelashes over the entire width of the eyelid, product, lengthen and curl them. The distance between the two faces being smaller that the width of the brush, it can easily slip into the corner of the eye to make up the eyelashes, without burrs around the corner of the eye. The sides of the brush, which have longer, and therefore more flexible, hairs than the faces, but which are less wide, allow very effective combing and separation of eyelashes. The back of the brush, like the hollow, allows to spread the makeup or care product in supporting the eyelash over a large part of the length of the eyelash. This back being curved, it promotes the curling of the eyelash.

Les caractéristiques très accentuées et nettement différentes des faces et des côtés confèrent à cette brosse un comportement dynamique surprenant : lorsque l'utilisateur fait tourner la brosse entre ses doigts, les cils sont alternativement chargés et recourbés puis peignés avec une intensité inhabituelle.The very accentuated and markedly different characteristics of the faces and sides give this brush a surprising dynamic behavior: when the user rotates the brush between his fingers, the eyelashes are alternately charged and curled then combed with unusual intensity.

De préférence, l'âme est centrale par rapport à chaque section transversale.Preferably, the core is central with respect to each cross section.

Selon une première variante de l'invention, on peut prévoir que la section transversale présente au moins deux côtés selon l'axe de plus grande longueur (Z-Z), ces côtés étant sensiblement parallèles à l'axe (Z-Z).According to a first variant of the invention, it can be provided that the cross section has at least two sides along the longest axis (Z-Z), these sides being substantially parallel to the axis (Z-Z).

Selon une seconde variante de l'invention, on peut prévoir que la section transversale présente au moins deux côtés selon l'axe de plus grande longueur (Z-Z), ces côtés étant de forme convexe. Selon cette variante, on peut prévoir que les côtés de la section transversale présentent deux extrémités, la largeur de la section selon l'axe (Y-Y), perpendiculaire à l'axe de plus grande longueur (Z-Z), à ces extrémités étant sensiblement nulle.According to a second variant of the invention, it can be provided that the cross section has at least two sides along the longest axis (Z-Z), these sides being convex. According to this variant, it can be provided that the sides of the section cross have two ends, the width of the section along the axis (Y-Y), perpendicular to the longest axis (Z-Z), at these ends being substantially zero.

Quelle que soit la variante de l'invention, on préfère que la section transversale présente au moins deux côtés selon l'axe (Y-Y), axe perpendiculaire à l'axe de plus grande longueur (Z-Z), ces côtés étant de forme convexe.Whatever the variant of the invention, it is preferred that the cross section has at least two sides along the axis (Y-Y), axis perpendicular to the axis of greatest length (Z-Z), these sides being convex in shape.

Avantageusement, la section transversale présente une largeur maximale (D) suivant l'axe de plus grande longueur (Z-Z) et une largeur maximale (d) suivant l'axe (Y-Y), D et d vérifiant la relation : D>1,5d Advantageously, the cross section has a maximum width (D) along the axis of greatest length (ZZ) and a maximum width (d) along the axis (YY), D and d verifying the relationship: D> 1.5d

Encore plus préférentiellement, D et d vérifient la relation : D>2d Even more preferably, D and d verify the relation: D> 2d

La plus grande longueur D peut varier le long de l'âme. Afin d'accentuer les caractéristiques de maquillage décrites ci-dessus, on préfère des brosses dont la surface enveloppe présente une section transversale allongée sur au moins 50% et préférentiellement 75%, de sa longueur.The greatest length D can vary along the core. In order to accentuate the makeup characteristics described above, brushes are preferred whose surface envelope has a cross section elongated over at least 50% and preferably 75%, of its length.

Avantageusement, les brosses selon l'invention sont prévues de telle sorte que pour chaque section transversale, l'axe de plus grande longueur et l'axe de plus grande largeur sont perpendiculaires.Advantageously, the brushes according to the invention are provided so that for each cross section, the axis of greatest length and the axis of greatest width are perpendicular.

Pour une plus grande facilité de manipulation, on prévoit de préférence que les extrémités de l'âme sont alignées sur l'axe X-X.For greater ease of handling, it is preferably provided that the ends of the core are aligned on the X-X axis.

L'invention a également pour objet un procédé de fabrication d'une brosse telle que décrite ci-dessus, caractérisé en ce qu'il comprend les étapes suivantes :

  • (i) réaliser une brosse de départ comportant une tige droite définissant un axe principal (X-X), une âme flexible, définissant la longueur de la brosse, cette âme comportant une première et une seconde extrémités, 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 une surface enveloppe de la brosse de départ,
  • (ii) tondre les poils de la brosse de départ de manière à ce que la surface enveloppe de la brosse présente sur au moins une partie de sa longueur, une section transversale de forme allongée selon un axe de plus grande longueur (Z-Z),
  • (iii) imprimer à l'âme une torsion principale dans le plan perpendiculaire à l'axe de plus grande longueur (Z-Z) et passant par la tige.
    • The subject of the invention is also a method of manufacturing a brush as described above, characterized in that it comprises the following steps:
  • (i) making a starting brush comprising a straight rod defining a main axis (XX), a flexible core defining the length of the brush, this core comprising first and second ends, 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 an envelope surface of the starting brush,
  • (ii) trimming the bristles of the starting brush so that the envelope surface of the brush has, over at least part of its length, a cross section of elongated shape along an axis of greatest length (ZZ),
  • (iii) impart to the core a main torsion in the plane perpendicular to the axis of greatest length (ZZ) and passing through the rod.

    • De préférence, dans une quatrième étape :
    (iv) on imprime une torsion secondaire 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 (X-X).    Preferably, in a fourth step:
    (iv) a secondary torsion is printed 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 (XX).

    Préférentiellement, on procède aux étapes (i) et (ii) de façon à ce que l'âme soit centrale par rapport aux faces de la brosse tondue droite.Preferably, steps (i) and (ii) are carried out so that the core is central with respect to the faces of the straight clipped brush.

    Préférentiellement, la brosse de départ est tondue de façon à ce que la surface enveloppe présente une section transversale allongée sur au moins 50%, et préférentiellement 75% de sa longueur.Preferably, the starting brush is mowed so that the surface envelope has a cross section elongated over at least 50%, and preferably 75% of its length.

    Selon un mode préféré de réalisation de l'invention on procède à l'étape (iii) de façon à imprimer à l'âme une torsion principale sensiblement circulaire.According to a preferred embodiment of the invention, step (iii) is carried out so as to imparting a substantially circular main torsion to the core.

    En outre, les poils des brosses selon l'invention peuvent être de toute espèce : poils de longueurs différentes, de diamètres différents ou de sections différentes et de matières différentes, poils à extrémités effilées, en forme de fourchette ou de tête d'épingle, ou ayant 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 sections and materials different, hairs with tapered ends, fork or pin head shape, or having 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 enveloppe 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 envelope surface of the brush. Such a variant of the invention allows to accentuate the loading of 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.

    L'invention a également pour objet un dispositif de maquillage comprenant un réservoir à mascara et un organe d'application de mascara tel que décrit ci-dessus.The invention also relates to a makeup device comprising a reservoir for mascara and a mascara applicator as described above.

    En raison de sa forme particulière, lorsque la brosse passe à travers un essoreur, ses côtés sont très bien essorés, tandis que ses faces le sont moins. En particulier, les faces sont essorées de façon non symétrique en raison de leur courbure. Cette particularité permet à l'utilsateur, en utilisant l'une ou l'autre des faces, de réaliser un maquillage variable en charge et en intensité sur toute la longueur de la paupière.Due to its special shape, when the brush passes through a wringer, its sides are very well wrung out, while its faces are less wrung out. In particular, the faces are wrung asymmetrically due to their curvature. This peculiarity allows the user, using one or other of the faces, to make up a make-up variable in load and intensity over the entire length of the eyelid.

    On peut ajuster la souplesse des poils et la souplesse de l'âme de façon à favoriser ou à contrarier l'essorage de la brosse.The flexibility of the hairs and the flexibility of the core can be adjusted so as to promote or to counter the spin of the brush.

    Afin de mieux faire comprendre l'objet de l'invention, on va décrire ci-après, à titre d'exemple, plusieurs brosses répondant aux caractéristiques de cette invention.In order to better understand the object of the invention, we will describe below, by way of for example, several brushes meeting the characteristics of this invention.

    Les figures 1, 1A et 2A sont des vues en perspective de brosses pouvant être utilisées pour fabriquer une brosse selon l'invention.Figures 1, 1A and 2A are perspective views of brushes that can be used to make a brush according to the invention.

    Les figures 1B et 2B sont des vues en perspective de brosses respectivement selon 1A et 2A qui ont été tondues suivant l'étape (ii) du procédé selon l'invention.Figures 1B and 2B are perspective views of brushes respectively along 1A and 2A which have been mowed according to step (ii) of the method according to the invention.

    Les figures 1C et 2C sont des coupes suivant les plans IC-IC et IIC-IIC des brosses représentées respectivement sur les figures 1B et 2B.Figures 1C and 2C are sections along the IC-IC and IIC-IIC planes of the brushes shown in Figures 1B and 2B respectively.

    Les figures 1D, 1E et 2D sont des vues en perspective de brosses selon l'invention, fabriquées suivant le procédé selon l'invention, respectivement à partir des brosses représentées sur les figures 1A et 2A.FIGS. 1D, 1E and 2D are perspective views of brushes according to the invention, manufactured according to the method according to the invention, respectively from brushes shown in Figures 1A and 2A.

    La figure 1E est issue de la figure 1D par une rotation de 90° autour de l'axe X-X.Figure 1E is taken from Figure 1D by a rotation of 90 ° around the axis X-X.

    La figure 3 est une vue en coupe d'un dispositif pour le maquillage des yeux.Figure 3 is a sectional view of a device for making up the eyes.

    La brosse 100 représentée sur les figures 1 et 1A 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 ces figures 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 105 de la brosse : c'est une surface de révolution convexe qui a la forme d'un ballon de rugby 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.The brush 100 shown in Figures 1 and 1A 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 these figures 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 105 of the brush: it is a surface of convex revolution which has the shape of a rugby ball and whose ends are constituted by two straight sections: the disc 106.a, of center 108.a and the disc 106.b from center 108.b.

    A l'aide d'une tondeuse, on découpe deux faces parallèles sensiblement planes dans la brosse de la figure 1A sur presque toute la longueur (mesurée selon l'axe X-X) de la brosse. Sur la figure 1A est représentée l'intersection (γ) de la surface 105 de la brosse avec le plan de tonte. On obtient une brosse tondue représentée sur les figures 1B et 1C.Using a clipper, two substantially flat parallel faces are cut from the brush of FIG. 1A over almost the entire length (measured along the axis X-X) of the brush. In FIG. 1A is shown the intersection (γ) of the surface 105 of the brush with the mowing plan. We obtain a clipped brush shown in FIGS. 1B and 1 C.

    Pour les éléments des figures 1B et 1C communs avec la figure 1A, les références des figures 1B et 1C sont les mêmes que celles de la figure 1A augmentées de 10.For the elements of FIGS. 1B and 1C common with FIG. 1A, the references of Figures 1B and 1C are the same as those in Figure 1A increased by 10.

    La brosse représentée sur les figures 1B et 1C comporte deux faces 119 parallèles entre elles et parallèles à l'axe X-X. Ces deux faces sont équidistantes de l'âme 112. La distance entre les deux faces est d. Les deux faces sont reliées par des bords arrondis 120. Sur la zone où ont été découpées les faces 119, les sections de la brosse suivant un plan perpendiculaire à X-X sont constituées de courbes 115c, représentées sur la figure 1C, sensiblement rectangulaires, de grande longueur D suivant l'axe de plus grande longueur Z-Z et de plus grande largeur d mesurée suivant l'axe de plus grande largeur Y-Y avec D>1,5d. Les deux faces ne s'étendent pas jusqu'aux extrémités 117a et 117b de la brosse. A ces extrémités, les sections 116a, 116b de la brosse sont circulaires. La courbe 115c est symétrique par rapport aux axes de plus grande longueur Z-Z et de plus grande largeur Y-Y.The brush shown in FIGS. 1B and 1C has two faces 119 parallel between them and parallel to the X-X axis. These two faces are equidistant from the core 112. The distance between the two faces is d. The two faces are connected by rounded edges 120. On the area where the faces 119 were cut, the sections of the following brush a plane perpendicular to X-X consist of curves 115c, represented on the Figure 1C, substantially rectangular, of great length D along the axis of plus greater length Z-Z and greater width d measured along the axis of greater width Y-Y with D> 1.5d. The two faces do not extend to the ends 117a and 117b of the brush. At these ends, the sections 116a, 116b of the brush are circular. The curve 115c is symmetrical with respect to the axes of greater length Z-Z and wider Y-Y.

    On imprime à l'âme 112, à l'aide d'un outil approprié, par exemple en la pressant longitudinalement autour d'un cylindre métallique, une première torsion dans le plan perpendiculaire aux faces 119, entre les sections 116.a et 116.b, de telle sorte que l'âme ait une forme sensiblement en arc de cercle, puis une seconde torsion, dans le même plan, entre l'extrémité 111.1 de la tige et le centre 118.a de la section d'extrémité de la brosse, de façon à aligner le centre 118.b de l'autre extrémité de la brosse sur l'axe principal X-X comme la première extrémité 118.a.The core is printed 112, using an appropriate tool, for example by pressing it longitudinally around a metal cylinder, a first twist in the plane perpendicular to faces 119, between sections 116.a and 116.b, so that the core has a shape substantially in an arc, then a second twist, in the same plane, between the end 111.1 of the rod and the center 118.a of the end section of the brush, so as to align the center 118.b of the other end of the brush with the axis main X-X as the first end 118.a.

    Par cette opération on obtient une brosse 120 selon l'invention représentée sur les figures 1D et 1E. Sur ces figures, les références affectées à des éléments analogues à ceux des figures 1B et 1C sont celles des figures 1B et 1C augmentées de 10.By this operation, a brush 120 is obtained according to the invention shown in the Figures 1D and 1E. In these figures, the references assigned to elements analogous to those of FIGS. 1B and 1C are those of FIGS. 1B and 1C increased by 10.

    La brosse des figures 1D et 1E a sensiblement la forme d'une cuillère allongée ; l'âme 122 décrit une courbe C1, sensiblement en arc de cercle. Toutefois, ses extrémités 128.a et 128.b sont alignées sur l'axe principal X-X. La brosse comprend deux faces 129a, 129b formant l'une 129a, le dos et l'autre 129b, le creux de la cuillère. Ces deux faces sont reliées par des bords arrondis 120. La surface 125 de la brosse est engendrée par une série de courbes 115c, telles que représentées sur la figure 1C, évoluant le long de l'âme 122; ces courbes sont sensiblement rectangulaires, d'axes de plus grande longueur (Z-Z) parallèles entre eux. A ses extrémités 127a, 127b, la brosse est engendrée par des courbes circulaires.The brush of Figures 1D and 1E has substantially the shape of an elongated spoon; the core 122 describes a curve C 1 , substantially in an arc. However, its ends 128.a and 128.b are aligned on the main axis XX. The brush comprises two faces 129a, 129b forming one 129a, the back and the other 129b, the hollow of the spoon. These two faces are connected by rounded edges 120. The surface 125 of the brush is generated by a series of curves 115c, as shown in FIG. 1C, evolving along the core 122; these curves are substantially rectangular, with axes of greater length (ZZ) parallel to each other. At its ends 127a, 127b, the brush is generated by circular curves.

    La figure 2A se distingue de la figure 1A par le fait que la surface 205 de la brosse de départ a la forme d'un tronc de cône.FIG. 2A is distinguished from FIG. 1A by the fact that the surface 205 of the brush departure has the shape of a truncated cone.

    A l'aide d'une tondeuse, on découpe deux faces arrondies, sécantes, dans la brosse de la figure 2A sur toute la longueur (mesurée selon l'axe X-X) de la brosse. On obtient une brosse tondue représentée sur les figures 2B et 2C. Using a clipper, cut two rounded, intersecting faces from the brush. FIG. 2A over the entire length (measured along the axis X-X) of the brush. We get a mowed brush shown in Figures 2B and 2C.

    Pour les éléments des figures 2B et 2C communs avec la figure 2A, les références des figures 2B et 2C sont les mêmes que celles de la figure 2A augmentées de 10.For the elements of FIGS. 2B and 2C common with FIG. 2A, the references of Figures 2B and 2C are the same as those in Figure 2A increased by 10.

    La brosse représentée sur les figures 2B et 2C comporte deux faces 219 arrondies et sécantes. Ces deux faces sont symétriques par rapport à l'âme 212. La distance entre les sommets des deux faces est d. d est sensiblement constante d'une extrémité de la brosse à l'autre. Les deux faces sont reliées par des bords 220 se terminant par des arêtes 220a. Les sections de la brosse suivant un plan perpendiculaire à X-X sont constituées de courbes 215c, représentées sur la figure 2C, ayant sensiblement la forme d'un oeil, de grande longueur D suivant l'axe de plus grande longueur Z-Z et de plus grande largeur d mesurée suivant l'axe de plus grande largeur Y-Y. D croít depuis une première extrémité 216b jusqu'à une seconde extrémité 216a avec D>2d sur la courbe 215c représentée sur la figure 2C. Les deux faces tondues s'étendent jusqu'aux sections d'extrémités 216a et 216b de la brosse. La courbe 215c est symétrique par rapport aux axes de plus grande longueur Z-Z et de plus grande largeur Y-Y.The brush shown in FIGS. 2B and 2C has two rounded faces 219 and intersecting. These two faces are symmetrical with respect to the web 212. The distance between the vertices of the two faces is d. d is substantially constant from one end of the brush to another. The two faces are connected by edges 220 ending in edges 220a. The sections of the brush in a plane perpendicular to X-X are consisting of curves 215c, shown in Figure 2C, having substantially the shape with one eye, of great length D along the axis of greatest length Z-Z and more large width d measured along the axis of greatest width Y-Y. D has been growing for a first end 216b to a second end 216a with D> 2d on the curve 215c shown in Figure 2C. The two mowed faces extend to the sections ends 216a and 216b of the brush. Curve 215c is symmetrical with respect to axes of greater length Z-Z and greater width Y-Y.

    On imprime à l'âme 212, à l'aide d'un outil approprié, par exemple en la pressant longitudinalement autour d'un cylindre métallique, une première torsion dans le plan perpendiculaire aux faces 219, entre les sections 216.a et 216.b, de telle sorte que l'âme ait une forme sensiblement en arc de cercle, puis une seconde torsion, dans le même plan, entre l'extrémité 211.1 de la tige et le centre 218.a de la section d'extrémité de la brosse, de façon à aligner le centre 218.b de l'autre extrémité de la brosse sur l'axe principal X-X comme la première extrémité 218.a.The core is printed 212, using an appropriate tool, for example by pressing it longitudinally around a metal cylinder, a first twist in the plane perpendicular to the faces 219, between sections 216.a and 216.b, so that the core has a shape substantially in an arc, then a second twist, in the same plane, between the end 211.1 of the rod and the center 218.a of the end section of the brush, so as to align the center 218.b of the other end of the brush with the axis main X-X as the first end 218.a.

    Par cette opération on obtient une brosse 200 selon l'invention représentée sur la figure 2D. Sur cette figure, les références affectées à des éléments analogues à ceux des figures 2B et 2C sont celles des figures 2B et 2C augmentées de 10.By this operation, a brush 200 according to the invention shown in the figure is obtained. 2D. In this figure, the references assigned to elements similar to those of Figures 2B and 2C are those of Figures 2B and 2C increased by 10.

    La brosse de la figure 2D a sensiblement la forme d'une cuillère allongée ; l'âme 222 décrit une courbe C2, sensiblement en arc de cercle. Toutefois, ses extrémités 228.a et 228.b sont alignées sur l'axe principal X-X. La surface 225 de la brosse comprend deux faces 229a, 229b formant l'une : 229a, le dos et l'autre : 229b, le creux de la cuillère. Ces deux faces sont reliées par une arête 230a. La surface 225 de la brosse est engendrée par une série de courbes 215c, telles que représentées sur la figure 2C, évoluant le long de l'âme 222; ces courbes ont sensiblement la forme d'un oeil, d'axes de plus grande longueur (Z-Z) parallèles entre eux.The brush of Figure 2D has substantially the shape of an elongated spoon; the core 222 describes a curve C 2 , substantially in an arc. However, its ends 228.a and 228.b are aligned on the main axis XX. The surface 225 of the brush comprises two faces 229a, 229b forming one: 229a, the back and the other: 229b, the hollow of the spoon. These two faces are connected by an edge 230a. The surface 225 of the brush is generated by a series of curves 215c, as shown in FIG. 2C, evolving along the core 222; these curves have substantially the shape of an eye, of axes of greater length (ZZ) parallel to each other.

    Dans les deux modes de réalisation de l'invention décrits ci-dessus on a employé des brosses de départ ayant la forme d'un ballon de rugby et une forme tronçonique, mais on peut également utiliser une brosse de départ ayant une forme choisie parmi : un cylindre, un double cône assemblé par les bases des deux cônes de taille identique, un poisson comme décrit par exemple dans la demande de brevet français publiée sous le numéro FR-A-2730910 , une cacahuète, un obus, une larme.In the two embodiments of the invention described above, starting brushes in the shape of a rugby ball and a truncated shape, but we can also use a starting brush having a shape chosen from: a cylinder, a double cone assembled by the bases of the two cones of identical size, a fish as described for example in the French patent application published under the number FR-A-2730910, a peanut, a shell, a tear.

    Le dispositif pour le maquillage des yeux représenté sur la figure 3 comprend un réservoir cylindrique 320, qui comporte un goulot 324, fileté, surmonté d'un joint d'étanchéité 325 et qui est rempli d'un mascara 315. Le réservoir 320 comporte dans son goulot un essoreur 321, le maintien en position de l'essoreur dans le goulot étant assuré grâce à un bourrelet 326 qui coopère avec l'épaulement séparant le goulot du réservoir 320 proprement dit. L'essoreur 321 est constitué, de façon connue, en une matière souple et élastique. Un applicateur est destiné à coopérer avec le réservoir 320. Cet applicateur est constitué d'un moyen de préhension 323 qui supporte l'organe d'application 330, comprenant une tige 322 et un organe d'application 301, identiques à ceux représentés sur les figures 1D ou 2D. Le moyen de préhension 323 a la forme d'un capuchon et comporte un filetage 323a qui coopère avec le filetage 324a du goulot du réservoir. L'obturation étanche du réservoir 320 est obtenue en vissant le moyen de préhension 323 sur le goulot 324 du réservoir muni de son joint 325.The device for making up the eyes shown in FIG. 3 comprises a cylindrical tank 320, which has a neck 324, threaded, surmounted by a seal sealing 325 and which is filled with a mascara 315. The reservoir 320 comprises in its neck of a wiper 321, the wiper being held in position in the neck being ensured thanks to a bead 326 which cooperates with the shoulder separating the neck from the reservoir 320 proper. The wiper 321 is made, in a known manner, of a material flexible and elastic. An applicator is intended to cooperate with the reservoir 320. This applicator consists of a gripping means 323 which supports the member application 330, comprising a rod 322 and an application member 301, identical to those shown in Figures 1D or 2D. The gripping means 323 has the form of a cap and has a thread 323a which cooperates with the thread 324a of the neck of the tank. The sealed closure of the reservoir 320 is obtained by screwing the means of gripping 323 on the neck 324 of the tank provided with its seal 325.

    Lorsque l'on extrait l'organe d'application 330 du réservoir, l'organe applicateur ayant la forme d'une brosse chargée de mascara passe à travers l'essoreur 321. Celui-ci essore les poils du dos de la brosse de façon plus importante que les poils du creux de la brosse. Les poils des côtés de la brosse sont très essorés.When the applicator member 330 is extracted from the reservoir, the applicator member having the shape of a brush loaded with mascara passes through the wiper 321. It wipes the bristles of the back of the brush more prominently than the bristles of the hollow of the brush. The bristles on the sides of the brush are very wrung out.

    A l'application sur les cils, la brosse charge les cils en produit par ses deux faces, puis elle étale le produit, allonge et recourbe le cil par ses faces de dos et de creux, elle peigne par ses côtés. Les poils des côtés étant très longs par rapport au reste des poils de la brosse et le peigne étant de faible épaisseur, les cils sont très bien pris en charge au cours du peignage qui est très efficace.When applied to the eyelashes, the brush loads the eyelashes with product from both sides, then she spreads the product, lengthens and curls the eyelash by its back and hollow faces, it comb by its sides. The hairs on the sides being very long compared to the rest of the hairs of the brush and the comb being thin, the eyelashes are very well taken care of during combing which is very effective.
