Description

L'invention concerne un ensemble d'application selon la revendication 1.The invention relates to a application set according to claim 1.

L'ensemble visĆ© par la prĆ©sente invention est du type comprenant un rĆ©servoir renfermant un produit et pourvu d'une extrĆ©mitĆ© ouverte sur laquelle est fixĆ©, de maniĆØre amovible, un bouchon faisant office d'Ć©lĆ©ment de prĆ©hension. Le bouchon est solidaire d'un organe d'application, gĆ©nĆ©ralement par l'intermĆ©diaire d'une tige, de sorte que l'organe d'application, en position fermĆ©e de l'ensemble, plonge en permanence dans ledit produit.The assembly targeted by the present invention is of the type comprising a reservoir containing a product and provided with an open end to which is attached, removable manner, a plug acting as a gripping element. The plug is secured to an applicator member, generally via of a rod, so that the application member, in the closed position of the assembly, plunges continuously into said product.

Le rĆ©servoir est destinĆ© Ć  contenir un produit de maquillage, et plus particuliĆØrement un mascara. Une dose de ce produit est prĆ©levĆ©e Ć  l'aide d'un tel applicateur, et appliquĆ©e sur la surface Ć  traiter.The reservoir is intended to contain a makeup product, and more particularly a mascara. A dose of this product is taken using such an applicator, and applied to the surface to be treated.

De nombreux applicateurs de ce type ont ƩtƩ proposƩs dans le passƩ, dans le but d'appliquer du mascara sur les cils, du vernis sur les ongles, de la poudre sur les joues ou de la teinture sur les cheveux.Many applicators of this type have been proposed in the past for the purpose to apply mascara on the eyelashes, polish on the nails, powder on the cheeks or dye on the hair.

Ainsi, on connaĆ­t par le document FR-A-2 607 372, au nom de la demanderesse, un applicateur sous forme d'une brosse de mascara, constituĆ©e, de poils, prĆ©sentant chacun, en surface, au moins une rainure capillaire s'Ć©tendant de maniĆØre rectiligne sur toute leur longueur. Les rainures capillaires constituent des emplacements de rĆ©serves de mascara, permettant Ć  l'application, un transfert rapide et efficace du mascara sur les cils, en vue d'un maquillage homogĆØne. Thus, it is known from document FR-A-2 607 372, in the name of the applicant, an applicator in the form of a mascara brush, consisting of bristles, each having, on the surface, at least one capillary groove extending from rectilinear way over their entire length. The capillary grooves constitute mascara supply slots, allowing the application, a transfer fast and effective mascara on the eyelashes, for a homogeneous makeup.

Par le document FR-A-2 759 872, Ć©galement au nom de la demanderesse, on connaĆ­t un applicateur de mascara sur les cils comportant un manche de profil sensiblement plat, et portant un organe d'application, ledit organe d'application Ć©tant constituĆ© d'une pluralitĆ© de poils, implantĆ©s sur une premiĆØre extrĆ©mitĆ© du manche, selon un arrangement perpendiculaire Ć  un plan passant par le manche. Les poils peuvent prĆ©senter une section droite (ou section transversale) cruciforme, en demi-cercle ou en Ā« S Ā». Ainsi, les poils prĆ©sentent en surface une ou respectivement deux gorges droites.By document FR-A-2 759 872, also in the name of the applicant, know a mascara applicator on eyelashes with a profile handle substantially flat, and carrying an application member, said application member being composed of a plurality of bristles, implanted on a first end of handle, in an arrangement perpendicular to a plane passing through the handle. The hairs may have a cross section (or cross section) cruciform, in a semicircle or "S". Thus, the hairs have on the surface a or respectively two straight grooves.

En outre, par le document FR-A-2 687 055, Ʃgalement au nom de la demanderesse, on connaƭt un applicateur de vernis Ơ ongles prƩsentant une touffe composƩe de deux types de poils, lesquels poils peuvent prƩsenter au moins une rainure capillaire longitudinale.In addition, by document FR-A-2 687 055, also in the name of applicant, we know a nail polish applicator with a tuft composed of two types of hair, which hair may present at less a longitudinal capillary groove.

Par ailleurs, le document WO 97/10374 dĆ©crit un procĆ©dĆ© de fabrication de fibres torsadĆ©es de section non circulaire, obtenues par torsion autour de leur axe central Ć  partir d'un mono-filament de section non cylindrique de rĆ©volution. Ce document cite des fibres de section ovale ou polygonale ou des mono-filaments prĆ©sentant un noyau pourvu d'au moins une nervure s'Ć©tendant parallĆØlement Ć  l'axe central du filament. De telles fibres sont torsadĆ©es aprĆØs extrusion. Ces fibres sont utilisables pour diffĆ©rentes sortes de brosses abrasives ou de nettoyage, ou bien pour les brosses Ć  dents, Ć  cheveux ou pinceaux et brosses cosmĆ©tiques d'application.Furthermore, the document WO 97/10374 describes a process for manufacturing fibers twisted non-circular section, obtained by twisting around their axis central from a monofilament of non-cylindrical section of revolution. This document refers to oval or polygonal section fibers or mono-filaments having a core provided with at least one rib extending parallel to the central axis of the filament. Such fibers are twisted after extrusion. These fibers can be used for different kinds of abrasive brushes or cleaning, or for toothbrushes, hair brushes and cosmetic application brushes.

Bien que ces applicateurs de l'art antĆ©rieur donnent des rĆ©sultats globalement satisfaisants, il est apparu souhaitable de disposer d'un applicateur permettant d'obtenir un maquillage Ć  la fois trĆØs chargĆ© et trĆØs homogĆØne, dont l'autonomie est supĆ©rieure Ć  celle des applicateurs connus. En effet, les applicateurs citĆ©s ci-dessus peuvent prĆ©senter l'inconvĆ©nient de perdre une bonne partie de leur charge en produit, notamment lorsque l'organe d'application est soumis Ć  une opĆ©ration d'essorage prĆ©alable Ć  l'application. Cet effet est d'autant plus sensible que les gorges ou rainures capillaires des poils sont raclĆ©es tout le long, lors de l'opĆ©ration d'essorage. Although these applicators of the prior art give results globally satisfactory, it appeared desirable to have an applicator to obtain a makeup both very loaded and very homogeneous, whose autonomy is superior to that of known applicators. Indeed, the applicators mentioned above may have the disadvantage of losing a good deal of their product load, in particular when the application body is subject to a spinning operation prior to application. This effect is even more sensitive that the grooves or hair grooves of the hairs are scraped all the way through, when the spinning operation.

Aussi, l'invention a pour but de fournir un applicateur disposant, notamment aprĆØs essorage, d'une rĆ©serve importante de produit. En outre, l'invention vise une application contrĆ“lĆ©e du produit, quelle que soit la zone de l'organe d'application, mise en contact avec le support Ć  traiter. Un tel applicateur est adaptĆ© au maquillage des cils.Also, the object of the invention is to provide an applicator having, in particular after spin, a large supply of product. In addition, the invention aims to controlled application of the product, whatever the area of the application organ, contacting the support to be treated. Such an applicator is adapted eyelash makeup.

L'invention a pour but, Ć©galement, de fournir un applicateur qui reste d'une fabrication simple et Ć©conomique, et d'une utilisation pratique. Par ailleurs, lorsque le produit Ć  appliquer est relativement fluide, l'invention a pour but de mieux maĆ­triser la vitesse d'Ć©coulement du produit lors de l'application.The object of the invention is also to provide an applicator which remains simple and economical manufacturing, and practical use. Otherwise, when the product to be applied is relatively fluid, the object of the invention is to better control the flow velocity of the product during application.

Un objet de l'invention consiste en un applicateur de mascara sur les cils, apte Ć  confĆ©rer un maquillage trĆØs rĆ©gulier des cils. Plus particuliĆØrement, l'un des objets de l'invention consiste en une brosse de mascara comportant des poils aptes Ć  se charger en mascara d'une maniĆØre plus importante qu'une brosse de mascara classique.An object of the invention is a mascara applicator on the eyelashes, able to give a very regular makeup eyelashes. In particular, one of the objects of the invention consists of a mascara brush with bristles able to load mascara in a more important way than a brush of classic mascara.

En effet, la demanderesse a constatĆ© que l'intersection des cils avec des poils comportant une gorge en hĆ©lice, dont est pourvue une brosse de mascara, Ć©pouse la forme de l'ensemble des cils d'une paupiĆØre. Contrairement aux brosses de l'art antĆ©rieur, une telle brosse provoque un gainage plus homogĆØne et complet de la surface entiĆØre de chaque cil. Ainsi, lorsque l'utilisatrice applique la brosse sur les cils, elle charge la base des cils en mascara sur toute la largeur de la paupiĆØre. Ensuite, en faisant tourner la brosse autour de son axe central elle libĆØre successivement le mascara chargĆ© dans la (ou les) gorge(s) des poils, sur toute la surface de chaque cil, tout en les peignant et en sĆ©parant la totalitĆ© des cils sur toute leur longueur. Une telle brosse permet d'obtenir un maquillage Ć  la fois chargĆ©, rĆ©gulier, allongeant et recourbant. Indeed, the plaintiff has found that the intersection of eyelashes with hair having a helical groove, which is provided with a mascara brush, marries the shape of all the eyelashes of an eyelid. Contrary to brushes of the prior art, such a brush causes a more homogeneous sheathing and complete the entire surface of each eyelash. So when the user applies the brush on the eyelashes, it loads the base of the mascara eyelashes over the entire width of the eyelid. Then, rotating the brush around its central axis successively releases the loaded mascara into the throat (s) of the hair, on the entire surface of each eyelash, while painting them and separating all eyelashes all along their length. Such a brush makes it possible to obtain a make-up at the once loaded, regular, lengthening and curling.

Selon un mode de rĆ©alisation, l'organe d'application comporte au moins une touffe constituĆ©e desdits poils, les poils Ć©tant orientĆ©s sensiblement parallĆØlement, une extrĆ©mitĆ© de la touffe Ć©tant fixĆ©e sur l'Ć©lĆ©ment de prĆ©hension par l'intermĆ©diaire d'une tige.According to one embodiment, the application member comprises at least one tuft consisting of said bristles, the bristles being oriented substantially in parallel, one end of the tuft being attached to the gripping element by through a rod.

Selon une disposition particuliĆØre de l'invention, ledit organe d'application peut ĆŖtre solidaire d'une extrĆ©mitĆ© libre d'un support. Dans ce cas, l'organe d'application est disposĆ© dans un plan dudit support et orientĆ© transversalement Ć  un axe longitudinal du support. Une telle disposition peut ĆŖtre adoptĆ©e, pour un applicateur de mascara sur les cils.According to a particular embodiment of the invention, said application member can to be secured to a free end of a support. In this case, the organ application is arranged in a plane of said support and oriented transversely to a longitudinal axis of the support. Such a provision may be adopted, for a mascara applicator on the eyelashes.

Selon un autre mode de rĆ©alisation, lesdits poils sont orientĆ©s, de maniĆØre sensiblement radiale sur l'organe d'application, par rapport Ć  une Ć¢me centrale ou excentrĆ©e. Dans ce cas, l'applicateur peut ĆŖtre utilisĆ© en tant que brosse de mascara.According to another embodiment, said bristles are oriented, in a manner substantially radially on the applicator member, with respect to a central core or eccentrically. In this case, the applicator can be used as a brush mascara.

Avantageusement, une telle Ć¢me est formĆ©e par l'enroulement de deux branches d'un fil mĆ©tallique de maniĆØre Ć  serrer les poils entre les branches enroulĆ©es de l'Ć¢me. Dans ce cas, on obtient une brosse du type Ā« goupillon Ā». De prĆ©fĆ©rence, l'Ć¢me dĆ©finit un axe confondu avec l'axe de l'applicateur.Advantageously, such a core is formed by the winding of two branches of a wire so as to tighten the bristles between the rolled branches of blade. In this case, we obtain a brush type "brush". Preferably, the soul defines an axis coincident with the axis of the applicator.

L'applicateur peut prĆ©senter des formes extĆ©rieures variables, Ainsi, le profil extĆ©rieur de l'applicateur, formĆ© par les extrĆ©mitĆ©s des poils, peut ĆŖtre ajustĆ© aux besoins, selon la nature du produit Ć  appliquer et la morphologie du support. Ce profil peut ĆŖtre obtenu, par exemple par tonte Ć  l'aide d'une tondeuse. L'applicateur peut comporter un mĆ©lange de poils d'une premiĆØre longueur et de poils d'une seconde longueur, supĆ©rieure Ć  la premiĆØre.The applicator may have variable external shapes, so the profile outside the applicator, formed by the ends of the bristles, can be adjusted to needs, depending on the nature of the product to be applied and the morphology of the support. This profile can be obtained, for example by mowing with a mower. The applicator may comprise a mixture of hairs of a first length and hair of a second length, greater than the first.

En outre, tout ou partie des poils des applicateurs, selon l'invention, peut ĆŖtre de tout type : Ć  extrĆ©mitĆ©s effilĆ©es ou arrondies, en forme de fourchette ou de tĆŖte d'Ć©pingle, ou avoir subi toutes sortes de traitement connu de l'homme du mĆ©tier. Ces poils peuvent ĆŖtre ondulĆ©s dans un plan ou conformĆ©s en spirale Ć©tirĆ©e.In addition, all or part of the bristles of the applicators, according to the invention, may be any type: with tapered or rounded ends, in the shape of fork or head pin, or have undergone all kinds of treatment known to those skilled in the art. These hairs may be wavy in a plane or shaped spiral stretched.

En ce qui, concerne la section transversale des poils, celle-ci peut s'inscrire, avantageusement, dans un cercle de diamĆØtre compris entre environ 6/100ĆØme de mm et environ 30/100ĆØme de mm.Regarding the cross section of the bristles, it can be registered, advantageously, in a circle with a diameter of between about 6/100 th of mm and about 30/100 th of mm.

En fonction de la nature de l'organe d'application ainsi que celle du produit Ć  appliquer, la longueur des poils peut ĆŖtre comprise, entre environ 2 mm et environ 25 mm. Dans le cas d'une brosse du type Ā« goupillon Ā», la longueur d'un poil est dĆ©finie par la distance entre ses deux extrĆ©mitĆ©s libres. Dans ce cas, la longueur des poils et est, par exemple, de l'ordre de 7 mm Ć  12 mm.Depending on the nature of the application organ and the nature of the product to apply, the length of the bristles can be between about 2 mm and about 25 mm. In the case of a brush type "brush", the length of a hair is defined by the distance between its two free ends. In this case, the length hair and is, for example, of the order of 7 mm to 12 mm.

Les poils peuvent ĆŖtre rĆ©alisĆ©s, par exemple, en polyamide, en polyester, en polyĆ©thylĆØne, en polypropylĆØne, en chlorure de polyvinyle, en tĆ©flon, en polyĆ©thylĆØne tĆ©rĆ©phthalate ou en Ć©lastomĆØre thermoplastique.The bristles may be made, for example, of polyamide, polyester, polyethylene, polypropylene, polyvinylchloride, teflon, polyethylene terephthalate or thermoplastic elastomer.

De faƧon avantageuse, ladite gorge hĆ©licoĆÆdale prĆ©sente un pas compris entre 1 mm et 20 mm, et de prĆ©fĆ©rence entre 1,5 mm et 10 mm, ou encore entre 2mm et 9 mm. Advantageously, said helical groove has a pitch of between 1 mm and 20 mm, and preferably between 1.5 mm and 10 mm, or between 2 mm and 9 mm.

De maniĆØre avantageuse, la gorge prĆ©sente une profondeur telle que le rapport profondeur de la gorge/diamĆØtre du cercle d'inscription soit compris entre 1/10 et 9/10. A titre purement indicatif, la profondeur de la gorge peut ĆŖtre comprise entre 2/100ĆØme de mm et 8/100ĆØme de mm.Advantageously, the groove has a depth such that the ratio of the depth of the groove / diameter of the inscription circle is between 1/10 and 9/10. For information only, the depth of the groove can be between 2/100 th of mm and 8/100 th of mm.

De prĆ©fĆ©rence, la forme de la section droite des poils est choisie parmi les sections cruciforme ; trilobe ; tetralobe ; ovale creuse ; cylindrique creuse ; rectangulaire creuse ; polygonale creuse ; en forme de Ā« 8 Ā», de Ā« C Ā», de Ā« S Ā», de Ā« E Ā», de Ā« F Ā», de Ā« H Ā», de Ā« I Ā», de Ā« L Ā», de Ā« N Ā», de Ā« W Ā», de Ā« V Ā» ; de forme d'Ć©toile ou de forme de croissant.Preferably, the shape of the cross section of the bristles is chosen from the cruciform sections; trilobe; tetralobe; oval hollow; hollow cylindrical; hollow rectangular; polygonal hollow; in the form of "8", "C", "S", E, F, H, I, L, N, W, V; of star shape or crescent shape.

L'invention se rapporte Ć  un ensemble d'application comportant un rĆ©servoir destinĆ© Ć  contenir le produit Ć  appliquer, apte Ć  ĆŖtre prĆ©levĆ© Ć  l'aide d'un applicateur tel que dĆ©fini prĆ©cĆ©demment.The invention relates to an application set comprising a container intended to contain the product to be applied, capable of being taken with the aid of a applicator as defined above.

Dans un tel ensemble d'application, pour pouvoir assurer un dosage correct du produit et sa rĆ©partition homogĆØne sur l'organe d'application, dans certains cas, un organe d'essorage peut ĆŖtre prĆ©vu, situĆ© avantageusement au voisinage de l'extrĆ©mitĆ© ouverte du rĆ©servoir. Un tel organe d'essorage est destinĆ© Ć  doser la quantitĆ© de produit prĆ©levĆ©e par l'applicateur, et Ć  le rĆ©partir, de maniĆØre rĆ©guliĆØre, sur l'organe d'application. De prĆ©fĆ©rence, un tel organe d'essorage est constituĆ© d'un matĆ©riau Ć©lastomĆ©rique, rĆ©alisĆ© Ć©ventuellement en mousse, et prĆ©sente au moins un passage apte Ć  ĆŖtre traversĆ© par l'organe d'application et, le cas Ć©chĆ©ant, par une portion de tige reliant l'organe d'application Ć  l'Ć©lĆ©ment de prĆ©hension. Ledit passage de l'organe d'essorage peut comporter au moins une lĆØvre d'essorage, ouverte ou jointive. Lorsque l'organe d'application est portĆ© par une tige plate, ce passage peut se prĆ©senter, sous forme d'au moins une fente s'Ć©tendant sur une partie substantielle de la section de l'organe d'essorage.In such an application set, in order to ensure a correct dosage of the product and its homogeneous distribution on the application organ, in some cases a wiper member may be provided, advantageously situated in the vicinity of the open end of the tank. Such a wiper member is intended to dose the quantity of product taken by the applicator, and to distribute it in a regular, on the organ of application. Preferably, such a wiper member is made of an elastomeric material, optionally made of foam, and has at least one passage capable of being traversed by the application member and, where appropriate, by a rod portion connecting the applicator member to the gripping. Said passage of the wiper member may comprise at least one spin lip, open or joined. When the application organ is carried by a flat stem, this passage may be in the form of at least one slot extending over a substantial portion of the section of the wiper member.

L'invention consiste, mis Ć  part les dispositions exposĆ©es ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-aprĆØs, Ć  propos d'exemples de rĆ©alisation dĆ©crits avec rĆ©fĆ©rence aux dessins ci-annexĆ©s, 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, examples of embodiments described with reference to the accompanying drawings, but which are in no way limiting.

Sur ces dessins :

  • la figure 1 reprĆ©sente une vue en coupe axiale d'un ensemble d'application de mascara, selon un premier mode de rĆ©alisation de l'invention ;
  • la figure 2 reprĆ©sente une vue en coupe axiale, d'un ensemble d'application de mascara, selon un 2ĆØme mode de rĆ©alisation de l'invention ;
  • les figures 3 Ć  18 illustrent, en vue en perspective, diffĆ©rents types de poils, utilisables pour la rĆ©alisation des ensembles d'application des figures 1 Ć  2.
On these drawings:
  • Figure 1 shows an axial sectional view of a mascara application set, according to a first embodiment of the invention;
  • Figure 2 shows an axial sectional view of a set of mascara application, according to a 2nd embodiment of the invention;
  • Figures 3 to 18 illustrate, in perspective view, different types of bristles, used for the realization of the application sets of Figures 1 to 2.

En rĆ©fĆ©rence Ć  la figure 1, on voit un ensemble d'application de mascara 1, d'axe central X, pour l'application d'un produit M contenu dans un rĆ©servoir cylindrique 2 et Ć©quipĆ© d'un applicateur 3. L'applicateur 3 comporte un bouchon 3a apte Ć  ĆŖtre fixĆ©, par vissage, sur le col 21 du rĆ©servoir et servant d'Ć©lĆ©ment de prĆ©hension. Le col 21 comporte un filetage externe 22, apte Ć  coopĆ©rer avec un filetage complĆ©mentaire 3b rĆ©alisĆ© sur la portion infĆ©rieure de la surface interne du bouchon 3a. Le bouchon 3a prĆ©sente une forme gĆ©nĆ©rale cylindrique allongĆ©e, permettant une prise en main aisĆ©e. Le bouchon 3a est pourvu d'une tige centrale 5 Ć©mergeant du cĆ“tĆ© infĆ©rieur du bouchon 3a. Cette tige 5 prĆ©sente une extrĆ©mitĆ© infĆ©rieure 5a sur laquelle est fixĆ©, par exemple par collage ou emboĆ­tage, un organe d'application 4.With reference to FIG. 1, we can see a set of mascara application 1, of axis central X, for the application of a product M contained in a cylindrical tank 2 and equipped with an applicator 3. The applicator 3 comprises a cap 3a capable of being fixed by screwing on the neck 21 of the reservoir and serving as a gripping element. The collar 21 has an external thread 22, able to cooperate with a thread complementary 3b made on the lower portion of the inner surface of the cap 3a. The plug 3a has a generally elongated cylindrical shape, allowing easy handling. The cap 3a is provided with a central rod 5 emerging from the lower side of the plug 3a. This rod 5 has an end 5a on which is fixed, for example by gluing or casing, a implementing body 4.

Le col 21 du flacon prĆ©sente un bord circulaire libre 23 dĆ©finissant une ouverture 10. Dans cette ouverture est montĆ© un organe d'essorage 8, formĆ© d'un matĆ©riau Ć©lastiquement dĆ©formable. L'organe d'essorage se prĆ©sente sous la forme d'un doigt de gant dont le fond est tournĆ© vers le rĆ©servoir 2. Le fond est ouvert, de maniĆØre Ć  former une lĆØvre d'essorage circulaire, apte, lors de l'extraction de l'applicateur 6 hors du rĆ©servoir, Ć  essorer d'abord la tige, puis Ć  enlever tout excĆØs de produit, sur l'organe d'application. En position de stockage, l'organe d'essorage est traversĆ© par la tige 5.The neck 21 of the bottle has a free circular edge 23 defining an opening 10. In this opening is mounted a wring member 8, formed of a material elastically deformable. The wiper member is in the form of a glove finger whose bottom is turned towards the tank 2. The bottom is open, in order to form a circular spin lip, suitable, during the extraction of the applicator 6 out of the tank, first squeeze the stem, then remove all excess of product, on the organ of application. In storage position, the organ spin is crossed by the rod 5.

L'organe d'application 4 montrĆ© sur la figure 1 est une brosse pour l'application de mascara sur les cils, comprenant une Ć¢me 4a allongĆ©e formĆ©e par torsade de deux branches d'un fil mĆ©tallique qui a Ć©tĆ© repliĆ© en U. L'Ć¢me 4a est fixĆ©e par emmanchement Ć  force, Ć  l'extrĆ©mitĆ© 5a de la tige 5. Des poils 9 sont implantĆ©s radialement entre les fils de l'Ć¢me 4a. Lorsque les branches du fil sont torsadĆ©es, les poils 9 sont serrĆ©s et maintenus entre les spires de l'Ć¢me 4a. La loupe A montre un poil torsadĆ© de section droite en forme de Ā« S Ā», S13. L'Ć¢me 4a peut ĆŖtre centrale. Dans ce cas, elle dĆ©finit un axe confondu avec l'axe X de la brosse. Elle peut Ć©galement ĆŖtre excentrĆ©e. Les poils 9, rĆ©alisĆ©s en fibres synthĆ©tiques et Ć©ventuellement floquĆ©s, sont choisis parmi les poils prĆ©cĆ©demment dĆ©finis, et illustrĆ©s, de maniĆØre non limitative, sur les figures 3 Ć  18. La brosse 4 peut comporter un mĆ©lange de poils de diffĆ©rents types (diffĆ©rents diamĆØtres, formes, sections, Ć©lasticitĆ©s, matĆ©riaux).The applicator member 4 shown in FIG. 1 is a brush for applying mascara to the eyelashes, comprising an elongated core 4a formed by twisting two branches of a wire which has been folded into a U. 4a core is fixed by press fitting, at the end 5a of the rod 5. Bristles 9 are implanted radially between the son of the core 4a. When the branches of the wire are twisted, the bristles 9 are tightened and held between the turns of the core 4a. The magnifying glass A shows a twisted hair of straight section in the shape of "S", S 13 . Soul 4a can be central. In this case, it defines an axis coinciding with the X axis of the brush. It can also be eccentric. The bristles 9, made of synthetic fibers and possibly flocked, are chosen from the hairs previously defined, and illustrated, without limitation, in FIGS. 3 to 18. The brush 4 may comprise a mixture of bristles of different types (different diameters shapes, sections, elasticities, materials).

La brosse peut prƩsenter toute forme connue, obtenue, par exemple en coupant les extrƩmitƩs des poils 9 Ơ l'aide d'une tondeuse.The brush may have any known shape obtained, for example by cutting the ends of the hairs 9 using a clipper.

La brosse conforme Ć  l'invention peut ĆŖtre fortement chargĆ©e en mascara. A son contact, la base des cils se charge elle-mĆŖme fortement en mascara. Lorsque l'utilisatrice fait tourner la brosse 4 sur elle-mĆŖme, les cils continuent Ć  ĆŖtre en contact avec la brosse sur toute leur longueur et continuent Ć  se charger tout en se courbant. Les poils de la brosse commencent Ć  peigner les cils. Lorsque l'utilisatrice continue de faire tourner la brosse sur elle-mĆŖme, les cils sont pris en charge par les poils dans une gorge G, d'orientation variable en fonction du degrĆ© d'interpĆ©nĆ©tration des cils dans la brosse, rĆ©partissant le produit sur tout le pourtour et sur toute la longueur de chaque cil, tout en le peignant. En d'autres termes, lors de l'opĆ©ration de maquillage, les micro-rĆ©servoirs que constituent les gorges changent de position par rapport au cil Ć  traiter, assurant un enduit homogĆØne du cil. The brush according to the invention can be heavily loaded with mascara. To his contact, the base of the eyelashes itself loads strongly with mascara. When the user rotates the brush 4 on itself, the eyelashes continue to be in contact with the brush over their entire length and continue to load while curving. The bristles of the brush begin to comb the lashes. When the user continues to turn the brush on itself, the eyelashes are taken in charge by the hairs in a groove G, of variable orientation depending on the degree interpenetration of the eyelashes in the brush, distributing the product over the entire around and along the length of each eyelash, while painting it. In others terms, during the make-up operation, the micro-reservoirs that constitute the throats change position relative to the eyelash to be treated, ensuring a coating homogeneous eyelash.

Ainsi, chaque cil est chargĆ© de faƧon homogĆØne aussi bien sur toute sa longueur que sur tout son pourtour II n'y a pas de diffĆ©rence sensible de maquillage entre les cils d'extrĆ©mitĆ© de la paupiĆØre et ceux du milieu. Les cils sont parfaitement sĆ©parĆ©s les uns des autres, allongĆ©s et recourbĆ©s. Thus, each eyelash is loaded homogeneously as well over its entire length that all around it There is no noticeable difference in makeup between the eyelashes of the end of the eyelid and those of the middle. Eyelashes are perfectly separated from each other, elongated and curved.

Sur la figure 2 on voit un applicateur Ć  mascara 206, qui se diffĆ©rencie de celle reprĆ©sentĆ©e Ć  la figure 1 par le fait que sa tige 205 est sensiblement plate. Elle prĆ©sente Ć  son extrĆ©mitĆ© libre 205a une largeur voisine de celle d'un ensemble 204 de poils 209, formĆ© dans le plan de la tige 205, de maniĆØre sensiblement perpendiculaire Ć  un axe de l'applicateur 206. Les poils 209 utilisĆ©s sont du mĆŖme type que ceux dĆ©crits en rĆ©fĆ©rences Ć  la figure 1 . L'autre extrĆ©mitĆ© de la tige 205 est fixĆ©e dans un manchon de prĆ©hension 203.In Figure 2 we see a mascara applicator 206, which differs from that represented in FIG. 1 by the fact that its rod 205 is substantially flat. She has at its free end 205a a width close to that of a set 204 of hairs 209, formed in the plane of the rod 205, substantially perpendicular to an axis of the applicator 206. The bristles 209 used are of the same type than those described with reference to FIG. The other end of the stem 205 is fixed in a gripping sleeve 203.

L'applicateur Ć  mascara 206 fait partie d'un ensemble de maquillage 201 comportant un rĆ©servoir 202 contenant un produit M, surmontĆ© d'un Ć©lĆ©ment porte-essoreur. L'Ć©lĆ©ment porte-essoreur est pourvu d'un col 210 sur lequel peut ĆŖtre fixĆ© le manchon 203. L'Ć©lĆ©ment porte-essoreur comporte en outre un Ć©paulement 223, sur lequel est montĆ© un organe d'essorage 208. Dans le cas prĆ©sent, l'organe d'essorage est formĆ© par une membrane en Ć©lastomĆØre ou en mousse, prĆ©sentant une fente 211, apte Ć  ĆŖtre traversĆ©e, lors du retrait et de l'applicateur 206, par une portion au moins de la tige 205 et par l'ensemble 204 des poils 209. Le plan d'implantation des poils 209 peut ĆŖtre Ć©galement inclinĆ© par rapport au plan passant par la tige 205.The mascara applicator 206 is part of a makeup set 201 having a reservoir 202 containing a product M, surmounted by an element holder wiper. The wiper element is provided with a neck 210 on which the sleeve 203. The wiper element may further comprise a shoulder 223, on which is mounted a wiper member 208. In the case present, the wiper member is formed by an elastomeric membrane or foam, having a slot 211, able to be crossed, during the withdrawal and the applicator 206, by at least a portion of the rod 205 and the assembly 204 209. The implantation plan of the bristles 209 may also be inclined by relative to the plane passing through the rod 205.

Lorsque l'on extrait l'applicateur 206 hors du rĆ©servoir, la brosse chargĆ©e de mascara passe Ć  travers l'essoreur 211. Celui-ci essore la face externe des poils, les gorges hĆ©licoĆÆdales des poils comportant une rĆ©serve importante de produit.When the applicator 206 is removed from the reservoir, the brush loaded with mascara passes through the wiper 211. This squeezes the outer face of the hair, the helical grooves of the bristles having a large reserve of product.

Lorsque les applicateurs visĆ©s par l'invention sont soumis Ć  une opĆ©ration d'essorage, avant application du produit, l'essorage est effectuĆ© de maniĆØre Ā« random Ā», c'est-Ć -dire la rĆ©partition du produit dans les profils hĆ©licoĆÆdaux est telle que des micro-rĆ©serves de produit sont prĆ©sentes sur chaque poil Ć  un niveau diffĆ©rent. Ces micro-rĆ©serves sont aptes Ć  assurer une rĆ©partition trĆØs homogĆØne du produit sur le support Ć  traiter. Les figures 3 Ć  18 illustrent des configurations de poils particuliĆØrement prĆ©fĆ©rĆ©s pour la rĆ©alisation des applicateurs 6, 206 dĆ©crits ci-dessus.When the applicators covered by the invention are subjected to an operation before the product is applied, the spin is carried out "Random", that is, the distribution of the product in the helical profiles is such as micro-product reserves are present on each hair at a different level. These micro-reserves are able to ensure a very homogeneous product on the support to be treated. Figures 3 to 18 illustrate particularly preferred hair configurations for producing the applicators 6, 206 described above.

La figure 18 montre une vue en perspective d'un poil dont la section S a la forme d'une Ć©toile, prĆ©sentant une pluralitĆ© d'Ć©videments E, de maniĆØre Ć  former, sur le poil une pluralitĆ© de gorges hĆ©licoĆÆdales G.FIG. 18 shows a perspective view of a pile whose section S has the shape a star, having a plurality of recesses E, so as to form, on the a plurality of helical grooves G.

La (ou les) gorge(s) hĆ©licoĆÆdale(s) peu(ven)t ĆŖtre du type Ā« lĆ©vogyre Ā», ce qui signifie que lorsqu'elles sont vues depuis l'axe du poil, elles progressent dans le sens opposĆ© au sens de rotation des aiguilles d'une montre.The helical groove (s) may be of the "levorotatory" type, which means that when viewed from the axis of the hair, they progress in the opposite direction of clockwise rotation.

La (ou les) gorge(s) hĆ©licoĆÆdale(s) peu(ven)t Ć©galement ĆŖtre du type Ā« dextrogyre Ā», ce qui signifie que lorsqu'elles sont vues depuis l'axe du poil, elles progressent dans le sens de rotation des aiguilles d'une montre.The helical groove (s) can also be of the type "Dextrorotatory", which means that when viewed from the axis of the hair, they progress in the direction of clockwise rotation.

Ainsi, il est possible de rĆ©aliser un applicateur formĆ© exclusivement de fibres dont la (ou les ) gorge(s) tourne(nt) toutes dans le mĆŖme sens, ou d'un mĆ©lange de fibres dont certaines tournent Ć  droite, tandis que les autres tournent Ć  gauche. On peut jouer ainsi sur les caractĆ©ristiques d'application du produit, notamment sur les cils.Thus, it is possible to produce an applicator formed exclusively of fibers of which the throat (s) turn (s) all in the same direction, or a mixture of fibers some of which turn right, while others turn left. This can be done on the application characteristics of the product, in particular on the eyelashes.

Ces poils peuvent ĆŖtre obtenus par extrusion d'un matĆ©riau thermoplastique au travers une buse prĆ©sentant un profil appropriĆ©, puis torsadĆ©s par torsion Ć  chaud autour de leur axe, selon le pas de la gorge hĆ©licoĆÆdale souhaitĆ©e. Les poils utilisĆ©s selon la prĆ©sente invention peuvent obtenus par un procĆ©dĆ© similaire Ć  celui dĆ©crit dans le document WO 97/10374 auquel il a Ć©tĆ© fait rĆ©fĆ©rence prĆ©cĆ©demment.These bristles can be obtained by extrusion of a thermoplastic material at through a nozzle having a suitable profile, then twisted by hot twist around their axis, according to the pitch of the desired helical groove. Hairs used according to the present invention can be obtained by a process similar to that described in WO 97/10374 to which reference has been made previously.

Avantageusement, la section transversale des poils ci-dessus s'inscrit dans un cercle dont le diamĆØtre est compris entre 6/100ĆØme de mm et 30/100ĆØme de mm.Advantageously, the cross section of the bristles above is in a circle whose diameter is between 6/100 th of mm and 30/100 th of mm.

Ils peuvent ĆŖtre rĆ©alisĆ©s en polyamide (PA6, PA6/6, PA11, PA6/10, PA6/12), en polyester, en polyĆ©thylĆØne, en polypropylĆØne, en copolymĆØre Ć©thylĆØne/propylĆØne, en chlorure de polyvinyle, en tĆ©flon, en polyĆ©thylĆØne tĆ©rĆ©phthalate ou en Ć©lastomĆØre thermoplastique. Le cas Ć©chĆ©ant, on peut incorporer dans ces matĆ©riaux des agents favorisant leur glissement, tel que le graphite, le bisulfure de molybdĆØne ou du tĆ©flon.They may be made of polyamide (PA6, PA6 / 6, PA11, PA6 / 10, PA6 / 12), polyester, polyethylene, polypropylene, ethylene / propylene copolymer, polyvinyl chloride, teflon, polyethylene terephthalate or thermoplastic elastomer. Where appropriate, one can incorporate in these materials of agents promoting their sliding, such as graphite, bisulphide molybdenum or teflon.

Il est bien entendu que ces poils Ć  profil hĆ©licoĆÆdal peuvent comporter, en outre, une quantitĆ© de poils non torsadĆ©s, de section bien connue dans l'art antĆ©rieur. A titre d'exemple, on peut citer les sections circulaire, polygonale, plate, trilobe, tetralobe, en Ā»L Ā», en Ā« C Ā», en Ā« U Ā», etc.. Ces poils non torsadĆ©s peuvent ĆŖtre pleins ou creux, par exemple cylindrique creux.It is understood that these helical profile bristles may further comprise a quantity of non-twisted hairs of section well known in the prior art. AT As an example, we can mention the circular, polygonal, flat, trilobe, tetralobe, "L", "C", "U", etc. These non-twisted hairs can be full or hollow, for example hollow cylindrical.

Dans un mĆŖme applicateur, pour les poils Ć  profil hĆ©licoĆÆdal ou non, le diamĆØtre de la section transversale du cercle dans lequel sont inscrits les poils peut prĆ©senter diffĆ©rents diamĆØtres. De mĆŖme, ils peuvent ĆŖtre constituĆ©s de matĆ©riaux diffĆ©rents.In the same applicator, for hairs with helicoidal profile or not, the diameter of the cross-section of the circle in which the bristles are have different diameters. Similarly, they can be made of materials different.

Dans la description dĆ©taillĆ©e qui prĆ©cĆØde, il a Ć©tĆ© fait rĆ©fĆ©rence Ć  plusieurs modes de rĆ©alisation prĆ©fĆ©rĆ©s de l'invention. Il est Ć©vident que des variantes peuvent y ĆŖtre apportĆ©es sans s'Ć©carter cadre de l'invention telle que revendiquĆ©e ci-aprĆØs.In the above detailed description, reference has been made to several modes preferred embodiment of the invention. It is obvious that variants can to be made without departing from the scope of the invention as claimed hereinafter.
