Definitions

  • the present invention relates to an applicator for applying a product to keratinous fibers, in particular eyelashes or eyebrows.
  • the invention relates to also to a set of the type comprising a container for containing a stock of product and such an applicator mounted at the end of a rod provided with a gripping element.
  • a wiper member may optionally be provided in the container for, during the extraction of the application element, to distribute the product on the applicator, and / or remove any excess product.
  • Packaging and application devices are known in which the application element is constituted by a comb-type applicator, having at less a row of teeth, able to load product when the applicator is extracted from the container containing the product.
  • the implantation of teeth or hair on a applicator is a key parameter for the application of the product, in particular on the eyelashes.
  • the implantation of teeth or hair on a applicator is a key parameter for the application of the product, in particular on the eyelashes.
  • the makeup will be light, loaded, curling, or lengthening, etc.
  • Comb type applicators are generally obtained entirely from molding, in particular of a thermoplastic material.
  • One of the problems to pose with such combs is the difficulty of multiplying types implanting teeth, and therefore, to multiply the types of makeup obtainable. Indeed, each new implantation of the teeth, in view to get a new makeup, requires the use of a new mold. By Moreover, some types of implantation can not be easily obtained from molding. In addition, making teeth having a small cross section, or having a complex shape, is not without problems.
  • brushes type "brushes” twisted comprising a core consisting of two branches of a wire twisted, so as to form helical turns. Prior to the stage of twist of the wire, is introduced between its two branches, a layer of bristles. After complete torsion, the hairs are tightened radially between the two branches twisted wire. The final shape of the brush is then obtained mowing the brush to the desired profile according to the desired makeup.
  • a disadvantage inherent in applicators of the above type is that the quantity of product taken, even after spinning, is often greater than quantity required for the application. As a result, residual product remains, likely to dry out between two applications.

  • such "gripping” allows the spreading of the product to the tip extreme eyelashes, and thus gives the illusion of longer eyelashes.
  • extending the application movement by a rotational movement around the axis of the applicator, the eyelashes thus gripped will adopt a movement of bending corresponding to the rotational movement of the applicator.

L'invention a trait également à un ensemble du type comportant un récipient pour contenir une réserve de produit et un tel applicateur monté au bout d'une tige munie d'un élément de préhension. Un organe d'essorage peut éventuellement être prévu dans le récipient pour, lors de l'extraction de l'élément d'application, répartir le produit sur l'applicateur, et/ou enlever tout excès de produit.The present invention relates to an applicator for applying a product to keratinous fibers, in particular eyelashes or eyebrows. The invention relates to also to a set of the type comprising a container for containing a stock of product and such an applicator mounted at the end of a rod provided with a gripping element. A wiper member may optionally be provided in the container for, during the extraction of the application element, to distribute the product on the applicator, and / or remove any excess product.

On connaít des dispositifs de conditionnement et d'application dans lesquels l'élément d'application est constitué par un applicateur du type peigne, ayant au moins une rangée de dents, aptes à se charger de produit lorsque l'applicateur est extrait du récipient contenant le produit.Packaging and application devices are known in which the application element is constituted by a comb-type applicator, having at less a row of teeth, able to load product when the applicator is extracted from the container containing the product.

Dans le domaine du maquillage, l'implantation de dents ou de poils sur un applicateur est un paramètre déterminant pour l'application du produit, notamment sur les cils. A chaque implantation, pour un produit ayant une rhéologie donnée, correspond un maquillage donné. Ainsi, en fonction de l'implantation des dents ou des poils, le maquillage sera léger, chargé, recourbant, ou allongeant, etc..In the field of make-up, the implantation of teeth or hair on a applicator is a key parameter for the application of the product, in particular on the eyelashes. At each implantation, for a product having a given rheology, matches a given makeup. So, depending on the implantation of the teeth or hairs, makeup will be light, loaded, curling, or lengthening, etc.

Bien évidemment il existe d'autres paramètres influant sur les caractéristiques d'application du produit, un des plus importants étant probablement le produit lui-même. Il en résulte un besoin d'adapter l'applicateur au produit en fonction du type de maquillage souhaité.Of course there are other parameters influencing the characteristics the most important of which is probably the product itself. This results in a need to adapt the applicator to the product according to the type of makeup desired.

Des applicateurs du type peigne sont généralement obtenus entièrement de moulage, notamment d'un matériau thermoplastique. Un des problèmes pouvant se poser avec de tels peignes tient à la difficulté de multiplier les types d'implantation des dents, et donc de ce fait, de multiplier les types de maquillage pouvant être obtenus. En effet, chaque nouvelle implantation des dents, en vue d'obtenir un nouveau maquillage, requiert l'utilisation d'un nouveau moule. Par ailleurs, certains types d'implantation ne peuvent pas être obtenues facilement de moulage. De plus, la réalisation de dents ayant une faible section transversale, ou ayant une forme complexe, n'est pas sans poser de problèmes. Comb type applicators are generally obtained entirely from molding, in particular of a thermoplastic material. One of the problems to pose with such combs is the difficulty of multiplying types implanting teeth, and therefore, to multiply the types of makeup obtainable. Indeed, each new implantation of the teeth, in view to get a new makeup, requires the use of a new mold. By Moreover, some types of implantation can not be easily obtained from molding. In addition, making teeth having a small cross section, or having a complex shape, is not without problems.

Pour le maquillage des cils, on connaít également des brosses de type "brosses torsadées" comprenant une âme constituée de deux branches d'un fil métallique torsadé, de manière à former des spires hélicoïdales. Préalablement à l'étape de torsion du fil de fer, on introduit entre ses deux branches, une nappe de poils. Après torsion complète, les poils sont serrés radialement entre les deux branches torsadées du fil de fer. La forme finale de la brosse est obtenue ensuite en tondant la brosse au profil recherché en fonction du maquillage souhaité.For the makeup of eyelashes, we also know brushes type "brushes" twisted "comprising a core consisting of two branches of a wire twisted, so as to form helical turns. Prior to the stage of twist of the wire, is introduced between its two branches, a layer of bristles. After complete torsion, the hairs are tightened radially between the two branches twisted wire. The final shape of the brush is then obtained mowing the brush to the desired profile according to the desired makeup.

Un inconvénient inhérent aux applicateurs du type précité tient au fait que la quantité de produit prélevé, même après essorage, est souvent supérieure à la quantité requise pour l'application. De ce fait, il reste du produit résiduel, susceptible de se dessécher entre deux applications.A disadvantage inherent in applicators of the above type is that the quantity of product taken, even after spinning, is often greater than quantity required for the application. As a result, residual product remains, likely to dry out between two applications.

En outre, et en dépit des progrès considérables effectués ces dernières années, en jouant notamment sur le type de poils, sur leur organisation, sur leur densité sur le diamètre des poils, ou sur le profil de la brosse, certaines implantations ne peuvent toujours pas être obtenues avec la technologie des brosses torsadées. Les limites du processus sont inhérentes au fait que, quoi qu'il arrive, les poils doivent suivre, au moins à leur base, le mouvement hélicoïdal du fil de fer qui les supporte.In addition, and despite the considerable progress made in recent years, by playing in particular on the type of hair, on their organization, on their density on the diameter of the bristles, or on the profile of the brush, certain implantations still can not be achieved with twisted brush technology. The limits of the process are inherent in the fact that, whatever happens, the hairs must follow, at least at their base, the helical movement of the wire which supports.

Aussi, existe t-il un besoin pour des applicateurs comportant des poils, ou touffes de poils, implantés selon de nouvelles configurations, en vue de l'obtention de nouveaux types de maquillage.Also, is there a need for applicators with bristles, or tufts? of hair, implanted according to new configurations, with a view to obtaining new types of makeup.

C'est en particulier un objet de l'invention que de réaliser un applicateur permettant d'obtenir un bon étalement du produit sur les fibres à traiter, et en outre, un allongement sensible et un recourbement desdites fibres.It is particularly an object of the invention to provide an applicator to obtain a good spread of the product on the fibers to be treated, and in addition, a substantial elongation and bending of said fibers.

C'est un autre objet de l'invention que de réaliser un tel applicateur qui soit simple d'utilisation, et économique à réaliser. It is another object of the invention to provide such an applicator which is simple of use, and economic to achieve.

Selon l'invention, ces objets sont atteints en réalisant un applicateur pour l'application d'un produit sur des fibres kératiniques, notamment les cils ou les sourcils, comportant un arrangement de poils rapportés sur un support non torsadé, et aptes à appliquer ledit produit, caractérisé par le fait que ledit arrangement est formé par au moins un premier groupe de poils disposés selon une première nappe, et au moins un second groupe de poils, disposés selon une seconde nappe, ledit arrangement étant tel que les poils de la première nappe se croisent avec les poils de la seconde nappe lorsque l'applicateur est observé transversalement à son axe longitudinal.According to the invention, these objects are achieved by making an applicator for the application of a product on keratinous fibers, in particular eyelashes or eyebrows, having an arrangement of bristles attached to a non twisted, and able to apply said product, characterized in that said arrangement is formed by at least a first group of bristles arranged according to a first ply, and at least a second group of bristles, arranged according to a second layer, said arrangement being such that the hairs of the first layer are cross with the hairs of the second layer when the applicator is observed transversely to its longitudinal axis.

Selon l'invention, les poils peuvent se toucher physiquement à l'endroit où ils se croisent, ou bien se croiser à distance les uns des autres, l'essentiel étant que lorsqu'une fibre est mise en engagement avec l'applicateur, transversalement à son axe, elle puisse être prise en charge entre deux poils, séparés selon une direction transversale à l'axe X, d'une distance pouvant être sensiblement nulle, et en tout état de cause, inférieure à la longueur de la fibre, et se croisant l'un par rapport à l'autre.According to the invention, the hairs can physically touch each other at the place where they are cross, or cross each other at a distance from each other, the essential point being that when a fiber is put into engagement with the applicator, transversely to its axis, it can be supported between two hairs, separated according to a direction transverse to the X axis, a distance that may be substantially zero, and in any case, less than the length of the fiber, and crossing one by report to the other.

Au sens de la présente invention, le terme "rapporté" traduit le fait que les poils sont fabriqués de façon séparée, en amont du processus de fabrication de l'applicateur, puis implantés sur l'applicateur, lors de la fabrication du support, ou après fabrication de ce dernier.For the purposes of the present invention, the term "reported" reflects the fact that the hairs are manufactured separately, upstream of the manufacturing process of the applicator, then implanted on the applicator, during the manufacture of the support, or after manufacture of the latter.

Ainsi, les poils peuvent être obtenus de manière classique par extrusion dans une filière, puis par découpe à la longueur requise. Les poils peuvent en outre faire l'objet de différents traitements, notamment chimiques, thermiques ou mécaniques. Ensuite, ils sont implantés sur le support, notamment lors du moulage de ce dernier, en surmoulant ou surinjectant le support sur les poils dont une extrémité est disposée dans le moule. Généralement, le support est constitué d'un matériau thermoplastique plus ou moins rigide. Alternativement, les poils peuvent être rapportés après moulage du support, notamment par collage, matriçage à chaud ou à froid, emboutissage, bouterollage, soudure ou agrafage. Thus, the bristles can be obtained conventionally by extrusion in a die, then cut to the required length. The hairs can also make subject of different treatments, in particular chemical, thermal or mechanical. Then they are implanted on the support, especially during the molding of the latter, overmolding or surinjecting the support on the hairs of which an end is disposed in the mold. Generally, the support is constituted a thermoplastic material more or less rigid. Alternatively, the hairs can be reported after molding of the support, in particular by gluing, hot or cold stamping, stamping, basting, welding or stapling.

Les poils peuvent être réalisés dans une matière identique ou différente de la matière formant le support. A titre d'exemple, les poils peuvent être en polyamide 6, 6-6, 6-10, 6-11, ou 6-12. Le support quant à lui, peut être notamment en polyéthylène, en polypropylène, ou en élastomère.The hairs can be made in a material identical or different from the material forming the support. By way of example, the bristles may be made of polyamide 6, 6-6, 6-10, 6-11, or 6-12. The support as for him, can be in particular in polyethylene, polypropylene, or elastomer.

Le produit visé par l'invention est notamment une composition de mascara, de consistance plus ou moins visqueuse. Une telle composition, lorsqu'elle est appliquée sur les cils, vise notamment à colorer ces derniers et/ou à les allonger, et /ou à les recourber. Elle peut en outre avoir un effet traitant.The product targeted by the invention is in particular a composition of mascara, consistency more or less viscous. Such a composition, when it is applied on the eyelashes, aims in particular to color them and / or to lengthen them, and / or curling them. It can also have a treating effect.

Selon un mode de réalisation, les poils sont disposés, au moins en partie, à l'intérieur desdites première et seconde nappes sous forme de touffes. Dans ce cas, une telle touffe peut être constituée de 2 à 200 poils, de préférence de 4 à 100 poils, et plus particulièrement de 5 à 50 poils.According to one embodiment, the bristles are arranged, at least in part, to the interior of said first and second webs as tufts. In this case, such a tuft may consist of 2 to 200 hairs, preferably 4 to 100 hairs, and more particularly from 5 to 50 hairs.

Selon une caractéristique très avantageuse de l'invention, les poils desdites première et seconde nappes se croisent à distance de leur(s) extrémité(s) libre(s). Ainsi, les portions de poils situées entre le point de croisement et l'extrémité libre des poils, définissent, en raison de l'orientation croisée des poils, des échancrures en « V » aptes à agripper les cils et à favoriser l'étalement du produit sur les cils, lorsque l'applicateur, chargé de produit, est mis en engagement avec ces derniers. En outre, un tel "agrippement" permet l'étalement du produit jusqu'à la pointe extrême des cils, et donne de ce fait l'illusion de cils plus longs. De plus, en prolongeant le mouvement d'application par un mouvement de rotation autour de l'axe de l'applicateur, les cils ainsi agrippés, vont adopter un mouvement de recourbement correspondant au mouvement de rotation de l'applicateur.According to a very advantageous characteristic of the invention, the hairs of said first and second webs intersect at a distance from their free end (s). Thus, the portions of bristles situated between the point of intersection and the free end hairs, because of the cross-orientation of the hairs, define notches in "V" able to grip the eyelashes and to promote the spreading of the product on the eyelashes, when the applicator, in charge of product, is put in engagement with these last. In addition, such "gripping" allows the spreading of the product to the tip extreme eyelashes, and thus gives the illusion of longer eyelashes. In addition, extending the application movement by a rotational movement around the axis of the applicator, the eyelashes thus gripped, will adopt a movement of bending corresponding to the rotational movement of the applicator.

Dans certains modes de réalisation, il peut être souhaitable que, en outre, les poils de la première nappe se croisent avec les poils de la seconde nappe, lorsque l'applicateur est observé selon son axe longitudinal. En d'autres termes, selon cette caractéristique, outre l'orientation croisée des poils d'une nappe par rapport aux poils de l'autre nappe, les nappes elles mêmes, se croisent l'une par rapport à l'autre. In some embodiments, it may be desirable that, in addition, the hairs of the first tablecloth intersect with the hairs of the second tablecloth, when the applicator is observed along its longitudinal axis. In other words, according to this characteristic, in addition to the cross orientation of the hairs of a sheet by compared to the hairs of the other tablecloth, the tablecloths themselves, intersect one by report to the other.

Selon un mode de réalisation, lesdites première et seconde nappes sont parallèles entre elles. Ainsi, les poils ou touffes de poils d'une nappe sont implantés sur le support selon une ligne d'implantation parallèle à la ligne d'implantation des poils ou touffes de poils de l'autre nappe.According to one embodiment, said first and second layers are parallel to each other. Thus, the hairs or tufts of hair of a tablecloth are implanted on the support along an implantation line parallel to the line implantation of the hairs or tufts of hair of the other tablecloth.

Les première et seconde nappes peuvent être disposées à distance l'une de l'autre. Cependant, selon un mode de réalisation préféré, lesdites première et seconde nappes sont au contact l'une de l'autre. Une telle configuration facilite la prise en charge des fibres à traiter par les échancrures en « V » dont il a été fait état précédemment.The first and second layers can be arranged remotely one of the other. However, according to a preferred embodiment, said first and second layers are in contact with each other. Such a configuration facilitates the management of the fibers to be treated by the "V" notches which have been made state previously.

Selon un autre mode de réalisation, lesdites première et seconde nappes sont non parallèles entre elles. Ainsi, les poils ou touffes de poils d'une nappe sont implantés sur le support selon une ligne d'implantation non parallèle à la ligne d'implantation des poils ou touffes de poils de l'autre nappe.According to another embodiment, said first and second plies are not parallel to each other. Thus, the hairs or tufts of hair of a tablecloth are implanted on the support according to an implantation line that is not parallel to the line implantation of the hairs or tufts of hair of the other tablecloth.

En outre, les première et seconde nappes peuvent être disposées respectivement dans un plan perpendiculaire à un plan d'implantation des poils sur le support.In addition, the first and second plies can be arranged respectively in a plane perpendicular to a plan of implantation of the bristles on the support.

Alternativement, lesdites première et seconde nappes peuvent être disposées respectivement dans un plan oblique par rapport au plan d'implantation des poils sur le support .Alternatively, said first and second plies can be arranged respectively in an oblique plane relative to the implantation plan of the hairs on the support.

Alternativement encore, l'une des nappes peut être disposée selon un plan perpendiculaire au plan d'implantation des poils, tandis que l'autre est disposée dans un plan oblique par rapport au plan d'implantation des poils.Alternatively again, one of the layers can be arranged according to a plane perpendicular to the implantation plan of the hairs, while the other is arranged in an oblique plane relative to the implantation plan of the hairs.

Ainsi, les première et seconde nappes peuvent diverger l'une par rapport à l'autre. Dans ce cas, les deux nappes forment entre elles un angle qui de préférence, est inférieur à 60°.Thus, the first and second plies may diverge relative to each other. In this case, the two sheets form between them an angle which preferably is less than 60 °.

De préférence cependant, lesdites première et seconde nappes convergent l'une par rapport à l'autre. Dans cette configuration, lesdites première et seconde nappes peuvent se croiser. La première nappe forme alors avec la seconde nappe un angle d'intersection, pouvant varier entre environ 15° et environ 165°. De préférence, lorsque les première et seconde nappes se croisent, elles se croisent à distance de l'extrémité libre des poils qu'elles contiennent. De cette manière, sont formés des « V », au fond desquels les cils sont pris en charge.Preferably, however, said first and second plies converge one compared to each other. In this configuration, said first and second tablecloths can cross each other. The first tablecloth then forms with the second ply an angle of intersection, which can vary between about 15 ° and about 165 °. Preferably, when the first and second layers intersect, they are cross at a distance from the free ends of the hairs they contain. Of this way, are formed of "V", at the bottom of which eyelashes are supported.

Le cas échéant, l'applicateur peut comprendre, en outre, un troisième groupe de poils disposés selon une troisième nappe. Selon une disposition particulière d'un applicateur à trois nappes, deux nappes sont parallèles entre elles, au moins une nappe supplémentaire étant disposée de sorte qu'elle se croise avec l'une et/ou l'autre des deux nappes parallèles entre elles.Where appropriate, the applicator may further comprise a third group of bristles arranged in a third layer. According to a particular provision of a three-ply applicator, two plies are parallel to each other, at least one additional layer being arranged so that it crosses with the one and / or the other of the two sheets parallel to each other.

Selon une disposition avantageuse de l'invention, à l'intérieur desdites nappes, les poils sont parallèles entre eux. Alternativement, certains poils de la nappe peuvent être selon une première orientation à l'intérieur de la nappe, tandis que d'autres poils de la même nappe sont d'une orientation différente.According to an advantageous arrangement of the invention, inside said layers, the hairs are parallel to each other. Alternatively, some hairs from the tablecloth may be in a first orientation within the web, while other hairs of the same ply are of a different orientation.

De même, à l'intérieur des nappes, les poils peuvent être de densité constante sur toute la longueur de la nappe ou de densité variable. Ainsi, il est possible notamment de prévoir au voisinage de l'extrémité libre de l'applicateur une zone de densité plus importante de poils de manière à favoriser le maquillage des cils du bas ou des cils du coin de l'oeil.Likewise, inside the plies, the bristles can be of constant density on the entire length of the sheet or variable density. So, it is possible in particular to provide in the vicinity of the free end of the applicator a zone greater density of hair so as to promote the makeup of the eyelashes from the bottom or eyelashes of the corner of the eye.

Selon un autre mode de réalisation, lesdites première et seconde nappes peuvent présenter, sur au moins une partie de leur longueur axiale, des hauteurs différentes. De cette façon, on donne aux poils de la nappe la plus haute une fonction plus prononcée de peignage et de séparation des cils.According to another embodiment, said first and second layers can present, on at least part of their axial length, heights different. In this way, the hairs of the highest tablecloth are more pronounced function of combing and separating the eyelashes.

Selon encore un autre mode de réalisation, l'une au moins desdites nappes peut être de hauteur variable, notamment de façon progressive, sur au moins une partie de sa longueur axiale. On peut ainsi adapter le bord libre de (ladite) lesdites nappe(s) au rayon d'implantation des cils sur les paupières. According to yet another embodiment, at least one of said layers can be of variable height, especially in a progressive manner, over at least one part of its axial length. It is thus possible to adapt the free edge of (said) said ply (s) at the eyelash implantation radius on the eyelids.

Selon un mode de réalisation particulier, le support est constitué d'au moins deux parties, notamment reliées par une charnière film, et assemblées entre elles, notamment par encliquetage, soudage ou collage, de manière à former ledit arrangement de poils. Une telle charnière-film peut être d'orientation perpendiculaire ou parallèle à l'axe longitudinal de l'applicateur. Les parties présentent, avantageusement, une conformation telle, que ledit arrangement final de poils n'est formé qu'après assemblage de ces parties. Ainsi, et selon un mode de réalisation avantageux, une première partie porte une première nappe de poils, tandis que la seconde partie porte une seconde nappe de poils. Ce n'est qu'en assemblant ces deux parties que l'on forme l'arrangement final recherché, c'est à dire un arrangement à deux nappes dont les poils se croisent.According to a particular embodiment, the support consists of at least two parts, in particular connected by a film hinge, and assembled together, in particular by snapping, welding or gluing, so as to form said arrangement of hairs. Such a hinge-film can be of orientation perpendicular or parallel to the longitudinal axis of the applicator. The parts present, advantageously, a conformation such that said final arrangement of hair is formed only after assembly of these parts. So, and in a way advantageous embodiment, a first part carries a first layer of hair, while the second part carries a second layer of hair. It's not that by assembling these two parts that we form the final arrangement sought, that is to say an arrangement with two layers whose hairs intersect.

Selon un autre mode de réalisation particulier, au moins l'une desdites nappes traverse le support et s'étend de part et d'autre de ce dernier. A cet effet, le support est traversé d'une multitude de perçages, non perpendiculaires au plan d'implantation des poils sur (ou dans) le support. Ensuite, les poils sont fixés dans les perçages, notamment par collage, matriçage à chaud ou à froid, emboutissage, bouterollage, soudure ou agrafage, etc.. On obtient ainsi de part et d'autre du support, deux portions d'application, identiques ou différentes, de manière à pouvoir conférer des caractéristiques d'application différentes en fonction de la portion d'application qui est mise en engagement avec les fibres à traiter.According to another particular embodiment, at least one of said layers crosses the support and extends on both sides of the latter. For this purpose, support is crossed by a multitude of holes, not perpendicular to the plane implantation of the bristles on (or in) the support. Then, the hairs are fixed in holes, especially by gluing, hot or cold stamping, stamping, basting, welding or stapling, etc.. other support, two application portions, identical or different, of in order to be able to confer different application characteristics in function of the application portion that is put into engagement with the fibers to treat.

Pour consolider l'implantation des poils dans le support, les poils peuvent comporter des aspérités, au moins sur la partie destinée à être implantée dans le support. Ceci est avantageux, notamment lorsque le support et les poils sont réalisés de matériaux différents, non compatibles entre eux, c'est à dire, inaptes à créer des liaisons physico-chimiques entre eux, notamment par thermofusion, lors de la surinjection ou du surmoulage du support autour des poils.To consolidate the implantation of the hairs in the support, the hairs can have asperities, at least on the part intended to be implanted in the support. This is advantageous, especially when the support and the hairs are made of different materials, not compatible with each other, that is to say, unfit for create physico-chemical bonds between them, especially by thermofusion, during overinjection or overmolding of the support around the hairs.

Dans le plan de la nappe qui les contient, les poils sont inclinés par rapport au plan du support selon un angle qui peut varier entre environ 30° et environ 150°. In the plane of the sheet which contains them, the hairs are inclined with respect to support plane at an angle that can vary between about 30 ° and about 150 °.

L'angle formé par les poils d'une nappe est différent de l'angle formé par les poils de l'autre nappe de manière à ce que, lorsque l'applicateur est observé de côté, les poils d'une nappe se croisent par rapport aux poils de l'autre nappe. De préférence, les poils d'une nappe sont orientés selon un angle inférieur à 90° par rapport au support, tandis que les poils de l'autre nappe sont orientés selon un angle de plus de 90° par rapport au plan d'implantation du support. De préférence, les poils d'une nappe sont inclinés de manière symétrique par rapport aux poils de l'autre nappe. Ainsi, les poils d'une nappe pourront être orientés à 90°-η, tandis que les poils de l'autre nappe seront de préférence sont orientés selon un angle de 90°+η, η étant de préférence au plus égal à 60°. Cette dernière caractéristique n'est toutefois en aucun cas, obligatoire.The angle formed by the bristles of a ply is different from the angle formed by the bristles the other web so that when the applicator is viewed from the side, the hairs of a web intersect with the hairs of the other web. Of preferably, the bristles of a ply are oriented at an angle of less than 90 ° compared to the support, while the hairs of the other layer are oriented according to a angle of more than 90 ° with respect to the support layout. Of preferably, the pile of a ply is inclined symmetrically with respect to to the hairs of the other tablecloth. Thus, the hairs of a tablecloth can be oriented to 90 ° -η, while the hairs of the other tablecloth will preferably be oriented at an angle of 90 ° + η, η being preferably at most equal to 60 °. This last characteristic is however in no way obligatory.

En ce qui concerne la nature des poils, ceux-ci peuvent être choisis, parmi les poils naturels ou synthétiques, notamment parmi les poils en polyéthylène, en polypropylène, en copolymère éthylène/propylène, en polyamide, en polyester, en chlorure de polyvinyle, en polytétrafluoroéthylène (téflon), en polyéthylène téréphthalate ou en élastomère thermoplastique. Les poils du dispositif peuvent être constitués de poils à section variable, par exemple creuse, plate ou polygonale et/ou de poils en élastomère, et/ou de poils présentant au moins une rainure capillaire, et/ou de poils torsadés autour de leur axe longitudinal, à droite ou à gauche, et/ou de poils dont les extrémités ont été meulées, et/ou de poils dont les extrémités libres sont arrondies, effilées, en forme de fourchette, de tête d'épingle ou de crochet, et/ou de poils de différentes longueurs, et/ou de poils incorporant des charges, notamment bactériostatiques, magnétiques, ou aptes à améliorer le glissement, et/ou de poils floqués, ou d'un mélange de tels poils.As regards the nature of the hair, these may be chosen from among the natural or synthetic bristles, especially from polyethylene bristles, polypropylene, ethylene / propylene copolymer, polyamide, polyester, polyvinyl chloride, polytetrafluoroethylene (teflon), polyethylene terephthalate or thermoplastic elastomer. The hairs of the device can consist of bristles of variable section, for example hollow, flat or polygonal and / or elastomeric bristles, and / or bristles having at least one hair groove, and / or twisted hairs around their longitudinal axis, on the right or left, and / or bristles whose ends have been ground, and / or bristles whose free ends are rounded, tapered, fork-shaped, head pin or hook, and / or hair of different lengths, and / or hair incorporating charges, in particular bacteriostatic, magnetic, or capable of improve sliding, and / or flocked hairs, or a mixture of such hairs.

Les agents destinés à améliorer le glissement des poils sur les fibres à traiter peuvent être choisis parmi le graphite, le bisulfure de molybdène ou le polytétrafluoroéthylène (téflon).Agents intended to improve the sliding of the hairs on the fibers to be treated may be selected from graphite, molybdenum disulfide or polytetrafluoroethylene (Teflon).

Avantageusement, on choisit des poils dont la section transversale s'inscrit dans un cercle de diamètre compris entre environ 6/100ème de mm et environ 30/100ème de mm, et de préférence entre 8/100ème de mm et 20/100ème de mm. Advantageously, one chooses bristles whose cross section fits in a circle of diameter between about 6/100 th of mm and about 30/100 th of mm, and preferably between 8/100 th of mm and 20/100 th of mm.

A titre d'exemple, la longueur apparente des poils, c'est à dire la longueur comprise entre le plan d'implantation sur le support et l'extrémité libre des poils, peut être comprise entre environ 0,5 mm et environ 20 mm, et de préférence, entre 1 mm et 10 mm.As an example, the apparent length of the hairs, ie the length between the implantation plan on the support and the free end of the bristles, may be from about 0.5 mm to about 20 mm, and preferably between 1 mm and 10 mm.

Selon une caractéristique très avantageuse de l'invention, l'applicateur peut être obtenu par surmoulage ou surinjection du support en un matériau approprié autour de l'une des extrémités desdits poils. En fonction des caractéristiques de maquillage souhaitées, le support peut être réalisé en un matériau thermoplastique rigide, semi-rigide ou souple, par exemple en élastomère ayant un module de flexion approprié.According to a very advantageous characteristic of the invention, the applicator can be obtained by overmoulding or overinjection of the support into a suitable material around one of the ends of said bristles. Depending on the characteristics of desired makeup, the support may be made of a material thermoplastic rigid, semi-rigid or flexible, for example elastomer having a suitable bending module.

L'applicateur peut être solidaire d'un élément de préhension auquel il est relié directement ou au moyen d'une tige.The applicator may be secured to a gripping element to which it is connected directly or by means of a rod.

L'invention a trait également, à un ensemble d'application d'un produit, notamment cosmétique, sur les cils ou les sourcils, comportant un récipient pour contenir une réserve de produit, éventuellement muni d'un organe d'essorage, et un applicateur tel que défini précédemment, apte à être disposé, de manière amovible, sur le récipient, ledit applicateur comprenant un élément de préhension. Un organe d'essorage approprié est décrit, par exemple dans le document FR-A-2 745 272.The invention also relates to a set of application of a product, particularly cosmetic, on the eyelashes or the eyebrows, comprising a container for contain a reserve of product, possibly provided with a wiper, and an applicator as defined above, able to be arranged in such a way removable, on the container, said applicator comprising a gripping element. A suitable wiper member is described, for example in document FR-A-2 745,272.

L'ensemble d'application de l'invention est utilisable, notamment, pour le maquillage et/ou le traitement des cils ou des sourcils.The application assembly of the invention can be used, in particular for the makeup and / or treatment of eyelashes or eyebrows.

Un ensemble d'application A pourvu d'un applicateur 1 conforme à l'invention est représenté sur la figure 1. Cet ensemble comporte un récipient 11 contenant une réserve d'un produit M cosmétique et/ou de traitement pour les cils ou les sourcils, par exemple une composition de mascara, de consistance plus ou moins visqueuse. An application set A provided with an applicator 1 according to the invention is shown in FIG. 1. This assembly comprises a container 11 containing a of a cosmetic product M and / or treatment for the eyelashes or eyebrows, for example a composition of mascara, more or less viscous.

Le récipient 11 est pourvu d'un col fileté 30 sur lequel est fixé, de manière amovible, un applicateur 1 conforme à l'invention. L'applicateur 1 est relié à un manchon de préhension 10 au moyen d'une tige 10a, d'axe X. Le manchon de préhension 10 constitue en outre un capuchon de fermeture du récipient, agencé pour se visser sur le col 30. Le col fileté 30 définit un orifice 11a, traversé, en position de stockage, par la tige 10a.The container 11 is provided with a threaded neck 30 on which is fixed, so removable, an applicator 1 according to the invention. Applicator 1 is connected to a gripping sleeve 10 by means of a rod 10a, of axis X. The sleeve of gripping member 10 further constitutes a cap for closing the container, arranged to screw on the neck 30. The threaded neck 30 defines an orifice 11a, crossed, in storage position, by the rod 10a.

L'orifice 11a du récipient 11 est pourvu intérieurement d'un organe d'essorage 19 constitué par un bloc de mousse élastiquement déformable, à cellules ouvertes ou semi-ouvertes, inséré dans une portion intérieure 30a du col 30. Le bloc de mousse 19 comporte un passage central 19a, apte à être traversé par l'applicateur 1 et par une portion de la tige 10a dont il est solidaire. Le passage 19a permet, lors de l'extraction de l'applicateur hors du récipient, d'étaler le produit M entre (et sur) les poils de l'applicateur 1 et d'enlever tout excès de produit M.The orifice 11a of the container 11 is internally provided with a wiper member 19 constituted by a block of elastically deformable foam, with open cells or semi-open, inserted into an inner portion 30a of the neck 30. The block of foam 19 has a central passage 19a, adapted to be traversed by the applicator 1 and a portion of the rod 10a which it is secured. The passage 19a allows, during the extraction of the applicator from the container, to spread the product M enters (and over) the bristles of the applicator 1 and remove any excess of product M.

Selon une variante non représentée, l'essoreur peut être constitué d'une lèvre annulaire formée par un manchon, en matériau élastomérique ou non, et monté dans le col du récipient 11.According to a variant not shown, the wiper may consist of a lip ring formed by a sleeve, of elastomeric material or not, and mounted in the neck of the container 11.

La tige 10a peut être rigide ou semi-rigide. Elle a été représentée rectiligne mais elle pourrait, en variante, être courbe.The rod 10a can be rigid or semi-rigid. She was shown straight but it could, alternatively, be curved.

En référence aux figures, 2a à 2d, on a représenté des principes généraux de l'invention.With reference to FIGS. 2a to 2d, there are shown general principles of the invention.

Ainsi, l'applicateur 1 illustré sur la figure 2a comporte un support 4 de forme allongée, s'étendant selon l'axe longitudinal X. Le support 4 comporte un plan d'implantation 5 sur lequel sont fixés des premier et second groupes P, S de poils rapportés 2, 3, arrangés sous forme de deux nappes planes. Le support 4 comporte deux portions d'extrémités avant 4a et arrière 4b. Elles présentent une hauteur correspondant sensiblement à la hauteur des poils avoisinants. La portion avant 4a est arrondie, de manière à éliminer tout angle risquant, à l'application, de blesser l'oeil. La portion arrière 4b se raccorde à une première extrémité de la tige 10a. La seconde extrémité de la tige 10a est solidaire du manchon de préhension 10 (non représenté sur la figure 2a).Thus, the applicator 1 illustrated in FIG. 2a comprises a support 4 of shape elongate, extending along the longitudinal axis X. The support 4 comprises a plane 5 on which are fixed first and second groups P, S of bristles reported 2, 3, arranged in the form of two flat sheets. The support 4 has two portions of front ends 4a and 4b rear. They present a height corresponding substantially to the height of the neighboring hairs. The part before 4a is rounded, so as to eliminate any risk angle, at the application, of hurt the eye. The rear portion 4b connects to a first end of the rod 10a. The second end of the rod 10a is integral with the gripping sleeve 10 (not shown in Figure 2a).

Chaque groupe de poils 2, 3 est agencé respectivement en une première et une seconde nappes P, S. les poils à l'intérieur de chaque nappe P, S, sont arrangés de sorte que, lorsque l'applicateur est vu transversalement à l'axe X, comme représenté sur la figure 2a, les poils 2 de la première nappe P se croisent avec les poils 3 de la seconde nappe S.Each group of bristles 2, 3 is arranged respectively in a first and a second plies P, S. the bristles inside each ply P, S, are arranged so that when the applicator is seen transverse to the X axis, like represented in FIG. 2a, the bristles 2 of the first ply P intersect with the bristles 3 of the second layer S.

La figure 2b illustre, en section transversale selon le plan II-II de la figure 2a, un premier mode de réalisation préféré d'un applicateur 1 pour l'application d'un produit, notamment un mascara, sur les cils ou les sourcils. Selon la figure 2b, la première nappe P formée par les poils 2, est parallèle à la nappe formée par les poils 3, les poils de la première nappe P touchant sensiblement les poils de la seconde nappe S. En d'autres termes, la distance séparant les deux nappes P et S est sensiblement nulle.FIG. 2b illustrates, in cross-section along plane II-II of FIG. 2a, a first preferred embodiment of an applicator 1 for the application of a produces, especially a mascara, on the eyelashes or the eyebrows. According to Figure 2b, the first ply P formed by the bristles 2, is parallel to the ply formed by the 3, the hairs of the first ply P substantially affecting the hairs of the second layer. In other words, the distance separating the two layers P and S is substantially zero.

La figure 2c illustre un agencement des nappes P, S similaire à l'agencement des nappes de la figure 2b, à la différence près que les nappes P, S sont disposées à distance l'une de l'autre. Ainsi, les poils 2 de la première nappe P ne sont pas en contact avec les poils 3 de la seconde nappe S. A titre indicatif, la distance séparant les deux nappes peut être de l'ordre de 1 mm à 1,5 mm.FIG. 2c illustrates an arrangement of the P, S sheets similar to the arrangement of the 2b, with the difference that the plies P, S are arranged at distance from each other. Thus, the bristles 2 of the first ply P are not in contact with the bristles 3 of the second layer S. As an indication, the distance separating the two layers may be of the order of 1 mm to 1.5 mm.

Comme représenté sur la figure 2d, le plan contenant la première nappe P diverge par rapport au plan contenant la seconde nappe S. Il est à noter que, selon l'exemple de réalisation considéré, au niveau du plan 5 du support, les bases des poils de la première nappe P sont situées à distance des bases des poils 3 de la seconde nappe S. Il est bien entendu que les bases des poils 2, 3 des première et seconde nappes P, S pourraient être jointives au niveau du plan 5. As represented in FIG. 2d, the plane containing the first layer P diverges from the plane containing the second S-sheet. It should be noted that, according to the exemplary embodiment considered, at the level of the plane 5 of the support, the bases of the hairs of the first tablecloth P are located away from the bases of the 3 of the second layer S. It is understood that the bases of the bristles 2, 3 first and second P, S sheets could be joined at the plane level 5.

Les figures 3a et 3b représentent un mode de réalisation suivant lequel deux nappes de poils P, S sont parallèles, disposées à distance d1 l'une de l'autre et ayant des hauteurs H1, H2 différentes. Ainsi, la première nappe P présente une hauteur constante H1, inférieure à la hauteur H2 de la seconde nappe S. Un tel arrangement favorise une bonne séparation des cils, lors de l'application du produit. Les poils 2, 3 sont implantés ici sur le plan d'implantation 5, de manière équidistante avec des intervalles d. On voit que les poils 2 de la première nappe P sont implantés sur le plan d'implantation 5 selon un angle β1, différent de l'angle d'implantation β2 des poils 3 de la seconde nappe S. Avantageusement, lesdits angles β1, β2 sont compris entre 30° et 150°. De préférence, l'angle β1 est inférieur à 90° et l'angle β2 égal ou supérieur à 90°, ou vice versa. Selon un exemple particulier, β1 est de l'ordre de 70°, tandis que, β2 est de l'ordre de 110°, de sorte que les poils 2 de la nappe P forment un angle d'environ 40° avec les poils 3 de la nappe S.Figures 3a and 3b show a following embodiment wherein two bristle plies P, S are parallel, arranged at a distance d1 from one another and having heights H 1, H 2 different. Thus, the first ply P has a constant height H 1 , less than the height H 2 of the second ply S. Such an arrangement promotes a good separation of the eyelashes, during the application of the product. The bristles 2, 3 are implanted here on the implantation plane 5, equidistantly with intervals d. It can be seen that the bristles 2 of the first ply P are implanted on the implantation plane 5 at an angle β 1 , different from the implantation angle β 2 of the bristles 3 of the second ply S. Advantageously, said angles β 1 , β 2 are between 30 ° and 150 °. Preferably, the angle β 1 is less than 90 ° and the angle β 2 equal to or greater than 90 °, or vice versa. According to a particular example, β 1 is of the order of 70 °, whereas, β 2 is of the order of 110 °, so that the bristles 2 of the sheet P form an angle of about 40 ° with the hairs 3 of the tablecloth S.

Il est bien entendu, que les nappes P, S peuvent alternativement être implantées selon les dispositions illustrées sur les figures 2b, 2d et 7b.It is understood that the layers P, S may alternatively be implanted according to the arrangements illustrated in Figures 2b, 2d and 7b.

Les nappes P, S formées sur l'applicateur illustré sur la figure 4, présentent une hauteur H variable, augmentant progressivement depuis l'extrémité libre 4a de l'applicateur en direction de la tige 10a. Le profil défini par l'extrémité libre des poils 2, 3 peut être rectiligne ou courbe, notamment concave ou convexe..The plies P, S formed on the applicator illustrated in FIG. variable height H, gradually increasing since the free end 4a of the applicator towards the rod 10a. The profile defined by the free end of bristles 2, 3 may be rectilinear or curved, in particular concave or convex.

Conformément à un autre mode de réalisation de l'invention, les figures 5a à 5d montrent, de manière similaire aux figures 2a à 2d et 7b, un applicateur 1 comportant, à la place de poils isolés, des touffes T de poils 2, 3. Ainsi, une première nappe P est définie par des touffes de poils 2, tandis qu'une seconde nappe S est définie par des touffes de poils 3. Une telle touffe T de poils 2, 3 peut être constituée de 2 à 200 poils, de préférence de 4 à 100 poils, et plus particulièrement de 5 à 50 poils.According to another embodiment of the invention, FIGS. 5a to 5d show, similarly to FIGS. 2a to 2d and 7b, an applicator 1 having, in place of isolated hairs, tufts T of bristles 2, 3. first ply P is defined by tufts of bristles 2, while a second web S is defined by tufts of bristles 3. Such tuft T of bristles 2, 3 can consist of 2 to 200 hairs, preferably 4 to 100 hairs, and more particularly from 5 to 50 hairs.

Les figures 6a et 6b illustrent, de manière plus détaillée, un mode d'implantation sur le support 5 de deux nappes P, S de poils 2, 3, suivant une même ligne d'implantation /. Les nappes P et S sont orientées de manière divergente. Un angle de divergence α est formé entre les deux nappes. L'angle α peut varier, avantageusement, entre 5° et 45°. Dans le mode de réalisation illustré, l'une des nappes P est dans un plan perpendiculaire au plan 5 du support 4. L'autre nappe S est dans un plan oblique par rapport au plan 5 d'implantation des poils sur le support. Les angles β1 et β2 d'orientation des poils 2, 3 à l'intérieur de chacune des nappes P, S, sont tels que définis précédemment.FIGS. 6a and 6b illustrate, in more detail, a mode of implantation on the support 5 of two plies P, S of bristles 2, 3, following the same implantation line /. The plies P and S are oriented in a divergent manner. An angle of divergence α is formed between the two layers. The angle α can vary, advantageously between 5 ° and 45 °. In the illustrated embodiment, one of the plies P is in a plane perpendicular to the plane 5 of the support 4. The other ply S is in an oblique plane relative to the plane 5 of implantation of the bristles on the support. The angles β 1 and β 2 of orientation of the bristles 2, 3 inside each of the plies P, S, are as defined above.

Les figures 7a à 7c illustrent un applicateur 1 comportant un plan d'implantation 5, sur lequel des première et seconde nappes P, S sont implantées. La nappe P est dans un plan interceptant le plan de la nappe S, selon une ligne L parallèle à l'axe X de l'applicateur et parallèle au plan d'implantation 5. Le plan de la nappe P forme un angle α1 avec le plan de la nappe S. La ligne d'implantation l1 de la nappe S est parallèle à la ligne d'implantation l2 de la nappe P. Les lignes d'implantation respectives sont à distance non nulle l'une de l'autre. La ligne d'intersection L est située à distance de l'extrémité libre des poils 2, 3.FIGS. 7a to 7c illustrate an applicator 1 comprising an implantation plane 5, on which first and second plies P, S are implanted. The ply P is in a plane intercepting the plane of the ply S, along a line L parallel to the axis X of the applicator and parallel to the implantation plane 5. The plane of the ply P forms an angle α 1 with the plane of the ply S. The implantation line 1 of the ply S is parallel to the implantation line 1 2 of the ply P. The respective implantation lines are at a non-zero distance from one of the other. The intersection line L is located at a distance from the free end of the bristles 2, 3.

La figure 7c montre que l'extrémité libre des poils 2, 3 peut être conformée en tête d'épingle 7, par exemple par un traitement thermique. De manière générale, les extrémités libres des poils peuvent être soumises à toute sorte de traitement mécanique, thermique ou chimique.FIG. 7c shows that the free end of the bristles 2, 3 can be shaped at the top pin 7, for example by a heat treatment. In general, free ends of the hairs can be subjected to any kind of treatment mechanical, thermal or chemical.

Les figures 8a et 8b illustrent des vues en perspective et en section transversale d'un mode de réalisation suivant lequel l'applicateur 1 comporte trois nappes P, R, S. Selon ce mode de réalisation, deux nappes P, S sont parallèles entre elles et implantées de manière oblique par rapport au plan d'implantation 5. La troisième nappe R est inclinée par rapport au plan d'implantation 5, de sorte que le plan qui la contient, d'une part, coupe le plan de la nappe P selon une ligne L' parallèle à l'axe X et parallèle au plan d'implantation 5, et d'autre part, coupe le plan de la nappe S selon une ligne L, parallèle à la ligne L'. La première ligne d'intersection L' est située à une distance du plan d'implantation 5, inférieure à la distance séparant le plan d'implantation 5 de la ligne L. Figures 8a and 8b illustrate perspective and cross-sectional views of an embodiment according to which the applicator 1 comprises three plies P, R, S. According to this embodiment, two sheets P, S are parallel to each other and implanted obliquely with respect to the implantation plane 5. The third ply R is inclined relative to the implantation plane 5, so that the plane which contains it, on the one hand, cuts the plane of the tablecloth P along a line L ' parallel to the X axis and parallel to the implantation plane 5, and on the other hand, cuts the plane of the sheet S along a line L, parallel to the line L '. The first line The intersection is located at a distance from the plan of implantation 5, less than distance between the layout plan 5 and the line L.

La figure 9 illustre une vue partielle en perspective d'un mode de réalisation semblable au mode de réalisation montré sur la figure 7a, à la différence près que les poils individuels 2, 3 sont remplacés par des touffes T constituées d'une pluralité de poils.FIG. 9 illustrates a partial perspective view of an embodiment similar to the embodiment shown in Figure 7a, with the difference that the individual hairs 2, 3 are replaced by tufts T consisting of a plurality of hairs.

Les figures 10a à 10d illustrent différents modes d'implantation des poils sur le plan d'implantation 5. A cet effet, des perçages d'implantation 21 peuvent être disposés de différentes manières dans le support 4. Selon la figure 10a, les perçages 21 sont disposés selon deux lignes d'implantation parallèles l, l1, dont l'une correspond à la première nappe P. L'autre correspond à la seconde nappe S. Les deux lignes d'implantation l, l1 sont séparées d'une distance d1 . Les perçages 21 de la ligne d'implantation l sont disposés en regard des perçages de l'autre ligne d'implantation l1. FIGS. 10a to 10d illustrate different modes of implantation of the bristles on the implantation plane 5. For this purpose, implantation holes 21 may be arranged in different ways in the support 4. According to FIG. 10a, the holes 21 are arranged along two parallel implant lines l , l 1 , one of which corresponds to the first ply P. The other corresponds to the second ply S. The two implant lines l , l 1 are separated from one another. distance d 1 . The bores 21 of the implantation line 1 are arranged opposite the bores of the other implantation line 1 .

Selon la figure 10b, les perçages 21 sont disposés selon deux lignes d'implantation parallèles l, l1 , dont l'une correspond à la première nappe P. L'autre correspond à la seconde nappe S. Les perçages 21 de chaque ligne d'implantation sont disposés en regard des perçages de l'autre ligne d'implantation. Selon ce mode de réalisation, les deux lignes d'implantation sont disposées à distance sensiblement nulle l'une par rapport à l'autre.According to Figure 10b, the holes 21 are arranged in two lines parallel implantation l, l 1, one of which corresponds to the first sheet P. The other corresponds to the second sheet S. The holes 21 of each line implantation are arranged opposite the holes of the other implantation line. According to this embodiment, the two implant lines are arranged at a substantially zero distance with respect to each other.

Selon la figure 10c, les perçages 21 sont disposés selon deux lignes parallèles d'implantation l, l1 , dont l'une correspond à la première nappe P. L'autre correspond à la seconde nappe S. Les deux lignes d'implantation l, l1 , sont séparées d'une distance non nulle d1 . Les perçages 21 de chaque ligne d'implantation sont disposés de façon décalée par rapport aux perçages de l'autre ligne d'implantation.According to FIG. 10c, the bores 21 are arranged along two parallel implant lines l , l 1 , one of which corresponds to the first sheet P. The other corresponds to the second sheet S. The two lines of implantation 1 , l 1 , are separated by a non-zero distance d 1 . The bores 21 of each implantation line are arranged offset from the bores of the other implantation line.

Selon la figure 10d, les perçages 21 sont disposés selon deux lignes d'implantation l, l1 divergentes dans le plan d'implantation 5. Les perçages 21 de chaque ligne d'implantation sont disposés en regard des perçages de l'autre ligne d'implantation à une distance variant progressivement. According to Figure 10d, the holes 21 are arranged in two lines implantation l, l 1 differing in the site plan 5. The bores 21 of each planting line are arranged opposite the holes of the other line implantation at a gradually varying distance.

La figure 10e illustre, de manière schématique la disposition de deux nappes P, S, implantées selon la configuration de la figure 10d, les nappes P, S étant orientées de façon oblique, l'une par rapport à l'autre, de manière à se couper selon une ligne L, non parallèle au plan d'implantation 5 des nappes P et S.FIG. 10e schematically illustrates the arrangement of two sheets P, S, implanted according to the configuration of FIG. 10d, the plies P, S being oriented obliquely to each other so as to cut themselves along a line L, not parallel to the implantation plane 5 of the P and S sheets.

La figure 10f illustre, de manière schématique la disposition de deux nappes P, S, implantées selon la configuration de la figure 10d, les nappes P, S étant contenues respectivement dans des plans perpendiculaires au plan d'implantation 5.FIG. 10f schematically illustrates the arrangement of two sheets P, S, implanted according to the configuration of FIG. 10d, the layers P, S being contained respectively in planes perpendicular to the layout plan 5.

La figure 11 illustre, schématiquement, une vue latérale sur d'un applicateur du type de celui illustré sur les figures 2a et 2b. Cependant, on voit que les poils 2, 3 ne sont pas disposés sur le plan d'implantation 5, de manière équidistante. En effet, dans une même nappe, P par exemple, les bases des poils 2 se trouvent séparées de distances variables d2 , d3 . Ainsi, sont définies deux lignes d'intersection L1, L2, situées à des hauteurs différentes par rapport au plan d'implantation 5. Les lignes L1 et L2 sont situées à distance de l'extrémité libre des poils. Les extrémités d'un couple de poils 2, 3 faisant partie chacun d'une nappe différente, forment ainsi des fourches en « V », dans lesquelles les cils C sont pris en charge, les cils étant orientés transversalement aux nappes P, S. De préférence, l'agencement des poils est tel, que les cils C s'insèrent dans les « V », sensiblement de manière individuelle. Ceci permet d'obtenir une bonne séparation des cils.Figure 11 illustrates, schematically, a side view of an applicator of the type shown in Figures 2a and 2b. However, it is seen that the bristles 2, 3 are not arranged on the implantation plane 5, equidistantly. Indeed, in the same layer, P for example, the bases of the bristles 2 are separated by variable distances d 2 , d 3 . Thus, two lines of intersection L 1 , L 2 are defined at different heights with respect to the implantation plane 5. The lines L 1 and L 2 are situated at a distance from the free end of the bristles. The ends of a pair of bristles 2, 3 each forming part of a different ply, thus form "V" forks, in which the eyelashes C are supported, the eyelashes being oriented transversely to the plies P, S. Preferably, the arrangement of the bristles is such that the eyelashes C fit into the "V", substantially individually. This makes it possible to obtain a good separation of the eyelashes.

Avantageusement, on choisit des poils présentant une flexibilité telle, que lors de la mise en contact d'un cil avec deux poils 2, 3 formant un « V », ces derniers puissent fléchir légèrement, comme illustré sur la figure 11 par les lignes pointillées. Le fait de disposer des lignes d'intersection à des hauteurs différentes, et d'utiliser des poils aptes à fléchir lors de l'application du produit, permet d'obtenir une nette amélioration du lissage du produit et donc un meilleur pouvoir tinctorial des cils. On obtient également un étalage du produit plus homogène, un meilleur recourbement des cils, et un allongement notable de ces derniers. Advantageously, bristles with such flexibility are chosen that, when contacting an eyelash with two bristles 2, 3 forming a "V", the latter may flex slightly as shown in Figure 11 by the lines dashed. Having intersecting lines at different heights, and to use hair able to flex during the application of the product, allows to obtain a clear improvement of the smoothing of the product and thus a better power tinctorial eyelashes. A more homogeneous product display is also obtained. better bending of the eyelashes, and a noticeable lengthening of the latter.

Selon un autre mode de réalisation de l'invention, comme illustré sur les figures 12, 13a et 13b, un applicateur 101 comporte un support constitué d'une première partie 4c et d'une seconde partie 4d, de forme allongée. Les deux parties 4c et 4d sont disposées de part et d'autre d'un axe X. Les deux parties 4c et 4d sont reliées entre elles par une charnière-film 20 s'étendant dans ledit axe X.According to another embodiment of the invention, as illustrated in the figures 12, 13a and 13b, an applicator 101 comprises a support consisting of a first part 4c and a second part 4d, of elongated form. Both parts 4c and 4d are arranged on either side of an axis X. The two parts 4c and 4d are interconnected by a film hinge 20 extending in said axis X.

Les poils 2 forment une première nappe P solidaire de la partie 4c. De manière analogue, une succession de poils 3 forme une seconde nappe S solidaire de la partie 4d. L'implantation des poils 2, 3 sur la partie correspondante du support est effectuée de sorte que les poils 2 de la première partie 4c forment un angle β1 avec cette dernière, différent d'un angle β2 formé entre les poils 3 et la seconde partie 4d.The bristles 2 form a first web P integral with the part 4c. Similarly, a succession of bristles 3 forms a second ply S secured to part 4d. The implantation of the bristles 2, 3 on the corresponding part of the support is carried out so that the bristles 2 of the first part 4c form an angle β 1 with the latter, different from an angle β 2 formed between the bristles 3 and the second part 4d.

La charnière film 20 permet de fabriquer l'applicateur 101 dans la configuration illustrée sur la figure 12, et d'assembler les deux parties 4c, 4d, par pivotement autour de l'axe X de ladite charnière-film, pour obtenir l'applicateur dans sa configuration d'utilisation, telle que représentée sur les figures 13a et 13b.The film hinge 20 makes it possible to manufacture the applicator 101 in the configuration illustrated in Figure 12, and to assemble the two parts 4c, 4d, by pivoting around the X axis of said film hinge, to obtain the applicator in its configuration of use, as shown in Figures 13a and 13b.

Le maintien en position repliée des deux parties 4c et 4d, l'une par rapport à l'autre, peut être assuré lors de l'insertion de l'applicateur dans un alésage formé par l'extrémité libre d'une tige destinée à recevoir l'applicateur 101. Alternativement, après rapprochement des deux parties 4c, 4d par pivotement autour de l'axe de la charnière-film 20, la fixation de la première partie 4c sur la seconde partie 4d peut être effectuée par des moyens de collage, de soudage ou d'encliquetage.Maintaining the folded position of the two parts 4c and 4d, one with respect to the other, can be ensured when inserting the applicator into a formed bore by the free end of a rod intended to receive the applicator 101. Alternatively, after approximation of the two parts 4c, 4d by pivoting around the axis of the film hinge 20, fixing the first part 4c on the second part 4d can be effected by gluing, welding or snap.

En ce qui concerne la configuration des poils résultant de l'assemblage des deux parties, on obtient un applicateur du type de celui décrit précédemment en référence aux figures 7a et 7b.Regarding the configuration of the bristles resulting from the assembly of the two parts, an applicator of the type described above is obtained. reference to Figures 7a and 7b.

Les figures 14a et 14b montrent un autre mode de réalisation d'un applicateur 201 comportant deux paires opposées P,S ; P',S' de nappes de poils 2, 3 traversant le support 4 de part en part. Le support 4 forme ainsi, sur deux faces situées à l'opposée l'une de l'autre, deux plans d'implantation 5, 5'. Il comporte une extrémité avant 4a, ainsi qu'une extrémité arrière 4b. Cette dernière est raccordée, comme décrit précédemment à une tige 10a. Le support 4 est pourvu de deux groupes de perçages 21a, 21b traversant le support selon des angles différents. Chaque perçage 21a, 21b est traversé par au moins un poil 2, 3, de manière à former des « V » de part et d'autre du support. On définit ainsi un applicateur à deux portions d'application.Figures 14a and 14b show another embodiment of an applicator 201 having two opposite pairs P, S; P ', S' of layers of bristles 2, 3 passing through the support 4 from side to side. The support 4 thus forms, on two faces located at the opposite of each other, two plans of implantation 5, 5 '. It has a front end 4a, and a rear end 4b. The latter is connected, as previously described to a rod 10a. Support 4 is provided two groups of holes 21a, 21b crossing the support at angles different. Each piercing 21a, 21b is traversed by at least one hair 2, 3, of way to form "V" on both sides of the support. We define a applicator with two application portions.

La fixation des poils dans le support 4 peut être effectuée, comme illustré sur la figure 14b, par matriçage du côté latéral du support 4, au moyen d'un outil approprié 30. Dans ces conditions, le support doit être constitué d'un matériau, notamment thermoplastique approprié, comme le polyéthylène ou le polypropylène.The fixing of the bristles in the support 4 can be carried out, as illustrated on the FIG. 14b, by stamping the lateral side of the support 4, by means of a tool In these circumstances, the support must consist of a material, particularly suitable thermoplastic, such as polyethylene or polypropylene.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits, et l'on peut notamment combiner entre elles les particularités de réalisation des différents exemples qui viennent d'être décrits.Of course, the invention is not limited to the embodiments which have just been described, and it is particularly possible to combine the particularities of realization of the various examples which have just been described.

L'applicateur pour cils ou sourcils de l'invention est réalisé de préférence par surmoulage ou surinjection de matière thermoplastique, de consistance sensiblement rigide, semi-rigide ou en élastomère, notamment en élastomère thermoplastique, de flexibilité appropriée. De manière sommaire, les poils, après mise à la longueur requise, sont pris selon leur orientation souhaitée, par exemple, au moyen d'une pince. Les extrémités des poils dépassant la pince sont ensuite introduites dans un moule, où le support est formé autour les extrémités des poils lors de ladite opération de surmoulage ou de surinjection. Il est possible de former simultanément la tige 10a, et éventuellement tout ou partie du manchon de préhension 10.The applicator for eyelashes or eyebrows of the invention is preferably made by overmoulding or overinjection of thermoplastic material, of consistency substantially rigid, semi-rigid or elastomeric, in particular elastomer thermoplastic, of appropriate flexibility. Briefly, the hairs, after the required length, are taken in their desired orientation, by for example, using a pair of pliers. The ends of the hairs protruding from the forceps are then introduced into a mold, where the support is formed around the ends bristles during said over-molding or over-injection operation. It is possible simultaneously forming the rod 10a, and possibly all or part of the sleeve grasping 10.
