Description

La présente invention a pour objet un applicateur pour appliquer un produit cosmétique sur les cils.The present invention relates to an applicator for applying a cosmetic product to the eyelashes.

Par « produit cosmétique », on entend toute composition telle que définie dans la Directive 93/35/CEE du Conseil du 14 juin 1993."Cosmetic product" means any composition as defined in Council Directive 93/35 / EEC of 14 June 1993.

La plupart des applicateurs pour appliquer un produit sur les cils, couramment appelés « brosses à mascara », connus de l'art antérieur, sont obtenus par un procédé industriel dans lequel on dispose, entre les deux branches d'une épingle métallique en forme de U, une série de poils indépendants disposés sensiblement côte à côte les uns des autres sur la longueur de l'espace interstitiel séparant les deux branches de l'épingle. Un effort de torsion est ensuite appliqué sur l'épingle ce qui conduit à son torsadage. Le torsadage de l'épingle entraîne lui-même un emprisonnement des poils entre les branches ainsi qu'un foisonnement hélicoïdal de ces poils, qui adoptent une distribution en nappes hélicoïdales. La réalisation d'un tel applicateur est notamment décrite dans le document US-4887622 .Most of the applicators for applying a product to the eyelashes, commonly known as "mascara brushes", known from the prior art, are obtained by an industrial process in which, between the two branches of a metal pin shaped U, a series of independent hairs arranged substantially side by side on the length of the interstitial space separating the two branches of the pin. A twisting force is then applied to the pin which leads to its twisting. The twisting of the pin itself entrains the trapping of the bristles between the branches and a helical swirling of these bristles, which adopt a distribution in helical layers. The realization of such an applicator is described in particular in the document US 4887622 .

On obtient ainsi une tête d'application qui est emmanchée sur une tige s'étendant à partir d'un organe de préhension, dans la continuité de ladite tige. Un tel organe de préhension est généralement conçu pour former un moyen de fermeture d'un récipient contenant le produit à appliquer au moyen de cette tête d'application.An application head is thus obtained which is fitted on a rod extending from a gripping member, in the continuity of said rod. Such a gripping member is generally designed to form a means for closing a container containing the product to be applied by means of this application head.

Ces brosses à mascara de l'art antérieur donnent généralement satisfaction. Ces brosses n'en présentent pas moins un certain nombre d'inconvénients.These mascara brushes of the prior art generally give satisfaction. These brushes nonetheless have a number of disadvantages.

La demande WO 2007/125207 décrit un autre type de brosse à mascara comportant un applicateur avec une âme recourbée en épingle sur laquelle est enfilée une pluralité de noyaux portant des éléments d'application sous la forme d'excroissances s'étendant depuis le noyau. Les deux branches de l'âme sont ensuite torsadées de manière à ce que les éléments d'application forment des nappes hélicoïdales. Avec un tel applicateur, l'utilisateur ne dispose que d'un seul type d'éléments d'application.The demand WO 2007/125207 discloses another type of mascara brush having an applicator with a bent-pinned core on which is threaded a plurality of cores carrying application elements in the form of protrusions extending from the core. The two branches of the core are then twisted so that the application elements form helical layers. With such an applicator, the user has only one type of application elements.

Il existe un besoin pour perfectionner encore les applicateurs, notamment pour permettre à l'utilisateur d'effectuer à l'aide d'un même applicateur, des actions diverses sur les cils. Il existe également un besoin pour des applicateurs qui aient un comportement lors de leur essorage, au sortir du récipient dans lequel ils sont trempés pour se charger en produit cométique, qui permette une charge optimale en produit tout le long de l'applicateur : ni trop, ni trop peu.
Il est également souhaitable de pouvoir bénéficier d'un applicateur offrant de nouvelles possibilités en termes d'orientation et de nature des éléments d'application, par exemple afin d'obtenir des rendus de maquillage différents ou parfaire un maquillage. En particulier, il existe un besoin pour améliorer la configuration de l'extrémité des brosses à mascara qui sont structurellement peu empoilées lorsqu'elles sont obtenues par le torsadage d'une épingle. La partie distale libre d'une brosse selon l'invention peut être utile pour pallier ce défaut.There is a need to further improve the applicators, in particular to allow the user to perform with the same applicator, various actions on the eyelashes. There is also a need for applicators that have a behavior during their spinning, out of the container in which they are soaked to load cometic product, which allows an optimal load of product all along the applicator: neither too much , neither too little.
It is also desirable to be able to benefit from an applicator offering new possibilities in terms of the orientation and nature of the application elements, for example in order to obtain different make-up renderings or perfect make-up. In particular, there is a need to improve the configuration of the end of mascara brushes that are structurally spoiled when they are obtained by twisting a pin. The free distal portion of a brush according to the invention may be useful to overcome this defect.

Un autre objet de l'invention vise à proposer un nouvel applicateur qui soit de construction particulièrement simple et bon marché, dont la construction et la fabrication reposent sur des principes techniques généraux simples et éprouvés, et qui soit déclinable en une multitude de variantes, tout en permettant d'obtenir un résultat de maquillage amélioré, et ou un excellent confort d'utilisation.
L'invention a pour but de répondre à tout ou partie de ces besoins et elle y parvient, selon l'un de ses aspects, grâce à un applicateur selon la revendication 1.Another object of the invention is to propose a new applicator which is of particularly simple and inexpensive construction, the construction and manufacture of which are based on simple and proven general technical principles, and which is available in a multitude of variants, all by allowing to obtain an improved makeup result, and or an excellent comfort of use.
The invention aims to meet all or part of these needs and it achieves, in one aspect, with an applicator according to claim 1.

De même, le document WO 2009/153753 décrit un applicateur comportant une pluralité d'organes d'applications composé chacun d'une pluralité de fibres individuelles.Similarly, the document WO 2009/153753 discloses an applicator having a plurality of application members each composed of a plurality of individual fibers.

Le document WO 2009/153761 décrit un applicateur comportant unique organe d'application formé d'une pluralité de fibres individuelles.The document WO 2009/153761 discloses an applicator having a single applicator member formed of a plurality of individual fibers.

Le document US 6408857 divulgue un applicateur pour appliquer un produit comportant une âme comprenant deux branches torsadées maintenant des poils. L'âme entoure un peigne réalisé en un seul tenant et comprenant des dents. L'extrémité distale de l'applicateur selon ce document est formée de branches torsadées comportant des poils.The document US 6408857 discloses an applicator for applying a product having a core comprising two twisted branches holding bristles. The soul surrounds a comb made in one piece and comprising teeth. The distal end of the applicator according to this document is formed of twisted branches having bristles.

Le document US 2009/0194128 divulgue un applicateur présentant une âme torsadée formée de deux branches sur lesquelles des éléments d'application individuels identiques en forme d'étoile 5, 6 sont successivement enfilés avant torsadage des branches, des fibres libres pouvant être insérées entre chaque éléments d'application individuels. Ces éléments d'application individuels comprennent un noyau pourvu d'orifices de passage pour les branches et présentant la forme d'une plaque.The document US 2009/0194128 discloses an applicator having a twisted core formed of two branches on which identical star-shaped individual application members 5, 6 are successively threaded before twisting of the limbs, free fibers insertable between each individual application members. These individual application elements comprise a core provided with passage openings for the branches and having the shape of a plate.

Le document US 2010/0071715 divulgue un applicateur à mascara comportant une âme torsadée comprenant deux types de poils : des poils normaux et des poils à mémoire de forme qui vont être déformés par deux torsions successives. L'applicateur selon ce document ne comporte qu'un seul organe d'application, les deux types de poils constituant des éléments d'application différents mélangés au sein d'un même organe d'application.The document US 2010/0071715 discloses a mascara applicator comprising a twisted core comprising two types of bristles: normal bristles and shape-memory bristles which will be deformed by two successive twists. The applicator according to this document has only one application member, the two types of bristles constituting different application elements mixed within the same application member.

Par exemple, le premier organe d'application peut comporter un corps et lesdits éléments d'application s'étendant à partir de ce corps, tel que les éléments d'application s'étendent selon au moins deux, de préférence au moins trois, directions radiales distinctes relativement au corps, avant insertion dans l'âme. Avantageusement, pour au moins une direction radiale, au moins un élément d'application peut s'étendre au niveau, voire au-delà d'une extrémité libre de l'âme. En particulier, un pied de raccordement de cet élément d'application au corps peut être situé au niveau de, voire au-delà de l'extrémité libre de l'âme. En particulier, lorsque l'âme est obtenue par le repliement d'un même brin sur lui-même de manière à former deux branches, le coude formé dans ce brin constitue l'extrémité distale de l'âme.For example, the first applicator member may comprise a body and said applicator elements extending from this body, such that the application elements extend in at least two, preferably at least three, directions. distinct radials relative to the body, before insertion into the soul. Advantageously, for at least one radial direction, at least one application element can extend at or even beyond a free end of the core. In particular, a connecting leg of this application element to the body may be located at or even beyond the free end of the core. In particular, when the core is obtained by folding a same strand on itself to form two branches, the bend formed in this strand is the distal end of the soul.

En particulier, lesdits éléments d'application peuvent foisonner hélicoïdalement du fait du torsadage de l'âme autour de ce premier organe d'application.In particular, said applicator elements may abound helically due to the twisting of the core around this first applicator member.

Par exemple, le degré de torsadage de l'âme peut varier sur la longueur de cette dernière.For example, the degree of twisting of the core may vary over the length of the latter.

Le premier organe d'application peut être réalisé par injection dans un moule de matière thermoplastique, élastomère ou non, ou d'un élastomère autre que thermoplastique ou encore réalisé par coulage d'une résine.The first applicator member may be made by injection into a mold of thermoplastic material, elastomeric or not, or an elastomer other than thermoplastic or made by casting a resin.

L'invention a également pour objet un dispositif de conditionnement et d'application comportant :

  • un applicateur selon l'invention, et
  • un produit cosmétique à appliquer sur les cils, notamment du mascara.
The invention also relates to a packaging and application device comprising:
  • an applicator according to the invention, and
  • a cosmetic product to be applied to the eyelashes, in particular mascara.

L'applicateur peut être retenu par une extrémité proximale au bout d'une tige du dispositif de telle sorte que le premier organe d'application est situé au niveau d'une extrémité distale de l'applicateur, opposée à l'extrémité proximale relativement à un axe longitudinal de l'applicateur. Ainsi le premier organe d'application permet un maquillage fin du coin de l'oeil, car son emplacement peut permettre d'éviter une charge excessive en produit au niveau de l'extrémité distale de l'applicateur.The applicator may be retained by a proximal end at the end of a shaft of the device such that the first applicator member is located at a distal end of the applicator, opposite the proximal end relative to a longitudinal axis of the applicator. Thus the first application member allows a fine makeup of the corner of the eye, because its location can to avoid excessive product loading at the distal end of the applicator.

En particulier, un tel dispositif peut comporter un récipient muni d'un essoreur pour coopérer avec l'applicateur et en réguler la charge en produit cosmétique, que ce soit au niveau du premier organe d'application comme au niveau du deuxième organe d'application. Ce même essoreur peut également coopérer avec ladite tige pour la nettoyer au sortir du récipient.In particular, such a device may comprise a container provided with a wiper to cooperate with the applicator and regulate the charge of the cosmetic product, both at the first applicator member and at the second applicator member. . This same wiper can also cooperate with said rod to clean it out of the container.

L'invention a aussi pour objet un procédé de fabrication d'un applicateur selon l'invention, comportant les étapes consistant à :

  • présenter les branches de l'âme non torsadées
  • disposer sur l'une des branches au moins, successivement le long de l'axe longitudinal de cette branche, le premier et le deuxième organe d'application
  • torsader l'âme de façon à induire un vrillage des branches et un vrillage de l'un au moins du premier et du deuxième organe d'application.
The invention also relates to a method of manufacturing an applicator according to the invention, comprising the steps of:
  • present the branches of the untwisted soul
  • arranging on at least one of the branches, successively along the longitudinal axis of this branch, the first and second application members
  • twisting the core so as to induce a twisting of the branches and twisting of at least one of the first and second application member.

Lorsque le premier et le deuxième organe d'application sont disposés successivement, avant torsadage, il peut n'y avoir aucun recouvrement axial, le long de l'axe longitudinal de la branche, entre ces deux organes d'application.When the first and second application members are arranged successively, before twisting, there may be no axial overlap, along the longitudinal axis of the branch, between these two application members.

Par exemple, selon ce procédé, on peut torsader l'âme de façon à induire un vrillage des branches sur toute la longueur où elles enserrent le premier et le deuxième organe d'application.For example, according to this method, it is possible to twist the core so as to induce twisting of the branches over the entire length where they enclose the first and the second application member.

On a représenté à la figure 1 un applicateur 1 selon un premier mode de mise en oeuvre de l'invention. Cet applicateur 1 comporte une tige 2 qui supporte une tête applicatrice 4 et qui peut s'étendre, comme illustré, de façon sensiblement rectiligne selon un axe X. En variante, la tige 2 peut s'étendre selon un axe longitudinal curviligne.Other advantages and objects of the invention will appear in more detail on reading the description which follows, and with the aid of the accompanying drawings provided for purely explanatory and non-limiting purposes, in which:

We have shown figure 1 an applicator 1 according to a first embodiment of the invention. This applicator 1 comprises a rod 2 which supports an applicator head 4 and which can extend, as illustrated, substantially rectilinearly along an axis X. Alternatively, the rod 2 may extend along a curvilinear longitudinal axis.

La tige 2 est reliée à une première extrémité 2a à un organe de préhension 3 conçu pour être saisi et manipulé manuellement par un utilisateur, par exemple entre deux ou trois doigts. L'applicateur 1 présente donc, de manière classique, un caractère portable et est destiné à une utilisation manuelle.The rod 2 is connected at a first end 2a to a gripping member 3 designed to be grasped and manipulated manually by a user, for example between two or three fingers. The applicator 1 therefore presents, in a conventional manner, a wearable character and is intended for manual use.

L'organe de préhension 3 est par exemple configuré pour être mis en place sur un récipient, non représenté, contenant par exemple du mascara, de façon à le fermer de façon étanche. Le produit à appliquer peut être liquide, semi-liquide, par exemple pâteux, ou encore pulvérulent. L'organe de préhension peut comporter une jupe de montage agencée pour se fixer sur le récipient, par exemple se visser sur un col du récipient. Le col du récipient peut supporter un essoreur de la tige 2 et de la tête applicatrice 4. La tige 2 peut présenter une section transversale circulaire, avec ou sans rétreint au niveau de sa portion venant se placer en regard de l'essoreur. La tige 2 est reliée, à une deuxième extrémité 2b opposée à la première extrémité 2a, à la tête applicatrice 4.The gripping member 3 is for example configured to be placed on a container, not shown, containing for example mascara, so as to close tightly. The product to be applied can be liquid, semi-liquid, for example pasty, or even powdery. The gripping member may comprise a mounting skirt arranged to attach to the container, for example to screw on a neck of the container. The neck of the container can support a wiper of the rod 2 and the applicator head 4. The rod 2 may have a circular cross section, with or without necking at its portion coming to be placed opposite the wiper. The rod 2 is connected, at a second end 2b opposite the first end 2a, to the applicator head 4.

Le récipient peut être muni de tout type d'organe d'essorage de la tige et de la tête applicatrice, réglable ou non, à lèvre élastomère, ondulée ou non, fendue ou non. La tête applicatrice 4 peut être reliée à la tige 2 par une portion flexible, élastiquement déformable.The container may be provided with any type of wiper member of the rod and the applicator head, adjustable or not, elastomeric lip, corrugated or not, split or not. The applicator head 4 can be connected to the rod 2 by a flexible, elastically deformable portion.

L'applicateur peut comporter une source vibrante, le cas échéant, et/ou être rotatif et/ou chauffant.The applicator may comprise a vibrating source, where appropriate, and / or be rotatable and / or heating.

La tête applicatrice 4 peut, comme représenté sur la figure 1, s'étendre selon un axe longitudinal rectiligne, confondu avec l'axe X de la tige. Dans des variantes non représentées, la tête applicatrice 4 s'étend selon un axe longitudinal s'étendant obliquement par rapport à l'axe X de la tige 2. La tête applicatrice 4 peut encore s'étendre selon une courbe.The applicator head 4 can, as represented on the figure 1 , extend along a rectilinear longitudinal axis, coincident with the axis X of the rod. In variants not shown, the applicator head 4 extends along a longitudinal axis extending obliquely with respect to the axis X of the rod 2. The applicator head 4 may also extend along a curve.

La tête applicatrice 4 comporte, conformément à l'invention, un premier organe d'application 5 et un deuxième organe d'application 6. La tête applicatrice 4 est conçue pour prélever du produit à appliquer, par exemple en étant immergé dans un récipient contenant ce dernier, et pour retenir et contenir cette quantité de produit prélevé jusqu'à son relâchement sur les cils, effectué de préférence par mise en contact et frottement de la tête applicatrice 4 avec et contre les cils. La tête applicatrice assure l'enduction des cils par du mascara, et une fonction de peignage et de séparation des cils.The applicator head 4 comprises, according to the invention, a first applicator member 5 and a second applicator member 6. The applicator head 4 is designed to take the product to be applied, for example by being immersed in a container containing the latter, and to retain and contain this amount of product taken until released on the eyelashes, preferably performed by contacting and rubbing the applicator head 4 with and against the eyelashes. The applicator head provides eyelash coating with mascara, and a combing and lash separation function.

Les premier et deuxième organes d'application peuvent être de couleurs différentes.The first and second application members may be of different colors.

Les poils 10 du deuxième organe d'application 6 sont par exemple choisis pour leur capacité à se charger en produit, en étant par exemple nombreux et fins, voire floqués, tandis que les éléments d'application du premier organe d'application 5 peuvent être choisis pour leur aptitude à séparer les cils, du fait d'une plus grande rigidité que les poils.The bristles 10 of the second applicator member 6 are for example chosen for their ability to load product, for example being numerous and thin, even flocked, while the application elements of the first applicator member 5 can be chosen for their ability to separate the eyelashes, because of greater rigidity than the hairs.

Les deux organes d'application 5 et 6 sont retenus par une âme 7 comportant deux branches 8 et 9 torsadées au moins partiellement l'une sur l'autre, les organes d'application étant retenus entre ces branches. Les deux branches peuvent provenir d'un même fil métallique replié sur lui-même en épingle avant d'être torsadé, comme représenté Figure 2.The two application members 5 and 6 are retained by a core 7 having two branches 8 and 9 twisted at least partially on one another, the application members being retained between these branches. The two branches can come from the same wire folded on itself hairpin before being twisted, as shown Figure 2 .

En section transversale, le diamètre des branches est compris entre 0,3 et 1 mm. Le fil métallique est par exemple en acier inoxydable. Les deux branches sont par exemple retenues dans un même logement réalisé à l'extrémité de la tige 2, par exemple en y étant vissé à chaud.In cross section, the diameter of the branches is between 0.3 and 1 mm. The wire is for example stainless steel. The two branches are for example retained in the same housing made at the end of the rod 2, for example by being screwed hot.

Le deuxième organe d'application 6 est constitué par des paquets de poils 10 disposés entre les deux branches. Un poil 10 du deuxième organe d'application s'étend au travers des branches de sorte de dépasser de deux côtés distincts de l'âme 7. Un poil est généralement tubulaire, d'un diamètre compris entre 15 et 35 centièmes de mm. Ils peuvent par exemple être pleins ou creux. Lors du vrillage des branches 8 et 9, les paquets de poils s'étalent entre les branches de manière à former une nappe de poils sensiblement homogène. Cette nappe de poil constitue la pluralité de poils. On peut ainsi compter pour le deuxième organe d'application entre 25 et 50 poils par spires, c'est-à-dire de 25 à 50 extrémités de poils comptées sur 180°.The second applicator member 6 consists of bundles of bristles 10 arranged between the two branches. A bristle 10 of the second applicator member extends through the branches so as to protrude from two distinct sides of the core 7. A bristle is generally tubular, with a diameter of between 15 and 35 hundredths of a millimeter. They can for example be full or hollow. During twisting of the branches 8 and 9, the bundles of bristles are spread between the branches so as to form a substantially homogeneous layer of bristles. This layer of hair constitutes the plurality of bristles. It is thus possible to count for the second applicator member between 25 and 50 bristles per turn, that is to say from 25 to 50 bristle ends counted over 180 °.

Ces poils 10 du deuxième organe 6 d'application peuvent être tous identiques entre eux, ou bien être formé par un rassemblement de paquets de diverses sortes de poils. De même, diverses opérations de mise en forme des poils peuvent être réalisées lorsque la tête applicatrice est réalisée, à partir du moment où les branches sont torsadées.These bristles 10 of the second applicator member 6 may all be identical to each other, or may be formed by a collection of packages of various kinds of bristles. Similarly, various hair shaping operations can be performed when the applicator head is made, from the moment the branches are twisted.

Les poils 10 peuvent par exemple être formés par au moins deux catégories différentes de poils, les catégories différant par exemple par le diamètre des poils, la forme de leur section transversale, la matière dont ils sont constitués, leur couleur ou encore leur longueur individuelle mesurée entre leur extrémité libre et l'âme 7. Cette longueur peut être modifiée lors d'une opération de mise en forme de la surface enveloppe du deuxième organe d'application. Les poils 10 sont par exemple en matière synthétique ou naturelle, par exemple en polyamide ou en Hytrel®.The bristles 10 may for example be formed by at least two different categories of bristles, the categories differing for example in the diameter of the bristles, the shape of their cross section, the material of which they are made, their color or their measured individual length. between their free end and the core 7. This length can be modified during a shaping operation of the envelope surface of the second applicator member. The bristles 10 are for example of synthetic or natural material, for example polyamide or Hytrel®.

On peut aussi faire subir aux poils 10 des traitements à chaud, de fusion des extrémités, des traitements d'abrasion ou des chocs mécaniques, par exemple pour former des fourches ou des coudes.The bristles may also be subjected to heat treatment, end fusion treatment, abrasion treatment or mechanical shock, for example to form forks or elbows.

Le premier organe d'application 5 comporte des éléments d'application 11 dressé depuis un corps 12. Le corps 12 peut présenter une section transversale circulaire ou autre, par exemple cruciforme, polygonale ou elliptique. Il est par exemple obtenu par injection, par exemple à partir de matière élastomérique, thermoplastique, par exemple du styrène-éthylène-butadiène-styrène (SEBS) ou un polyester élastomère tel que de l'HYTREL®. De préférence, il est réalisé dans une matière souple, déformable, par exemple d'une dureté d'environ 40 Shore, à partir d'un matériau plastique ou élastomérique, et par exemple en polymère.
Les éléments d'application 11 sont obtenus de moulage dans la même matière que le corps ou dans une matière différente, étant dans ce cas par exemple surmoulés sur le corps 12. Les éléments d'application 11 peuvent être distincts et indépendants du corps 12 et être fixés sur ce dernier par tout moyen approprié, et par exemple par collage, flocage, thermosoudure, sertissage ou assemblage mécanique, sans pour autant que l'on sorte du cadre de l'invention.The first application member 5 comprises application elements 11 raised from a body 12. The body 12 may have a circular cross section or other, for example cruciform, polygonal or elliptical. It is for example obtained by injection, for example from thermoplastic elastomeric material, for example styrene-ethylene-butadiene-styrene (SEBS) or an elastomeric polyester such as HYTREL®. Preferably, it is made of a flexible, deformable material, for example with a hardness of about 40 Shore, from a plastic or elastomeric material, for example polymer.
The application elements 11 are obtained by molding in the same material as the body or in a different material, being in this case for example overmolded on the body 12. The application elements 11 may be distinct and independent of the body 12 and to be fixed on the latter by any appropriate means, and for example by gluing, flocking, heat sealing, crimping or mechanical assembly, without departing from the scope of the invention.

Dans l'invention, le premier organe d'application est réalisé d'un seul tenant, c'est-à-dire qu'il est monobloc, ou en d'autres termes qu'il présente un caractère unitaire. Cela implique qu'il n'est pas formé par la réunion d'une pluralité de pièces élémentaires distinctes et indépendantes, mais constitue bien à lui seul une entité unitaire. Ce caractère unitaire, monobloc, contribue à simplifier la fabrication et la construction de l'applicateur 1 conforme à l'invention, ce qui s'avère précieux pour l'industrialisation de la fabrication de l'instrument 1 et la tenue mécanique de ce dernier.
Avantageusement, le corps 12 est sensiblement longiligne et présente un axe d'allongement principal matérialisé par l'axe Y, qui est de préférence confondu avec l'axe longitudinal de la tête applicatrice 4.
Les éléments d'application 11 sont disposés sur le corps 12, préalablement au torsadage de ce dernier, de manière à s'étendre selon au moins trois directions radiales distinctes autour dudit axe d'allongement principal Y, et de préférence selon au moins quatre directions radiales D1, D2, D3, D4 distinctes autour dudit axe Y. En d'autres termes, les éléments d'application 11 sont implantés selon au moins trois positions angulaires différentes autour de l'axe d'allongement principal Y, de telle sorte qu'ils adoptent une disposition tridimensionnelle sur le corps 12 non encore torsadé (illustré aux figures 2 à 5).In the invention, the first application member is made in one piece, that is to say it is monoblock, or in other words that it has a unitary character. This implies that it is not formed by the union of a plurality of distinct and independent elementary parts, but is in itself a unitary entity. This unitary character, monobloc, contributes to simplify the manufacture and construction of the applicator 1 according to the invention, which is invaluable for the industrialization of the manufacture of the instrument 1 and the mechanical strength of the latter .
Advantageously, the body 12 is substantially elongate and has a main axis of elongation materialized by the Y axis, which is preferably coincident with the longitudinal axis of the applicator head 4.
The application elements 11 are arranged on the body 12, prior to the twisting thereof, so as to extend along at least three distinct radial directions around said main elongation axis Y, and preferably in at least four directions distinct radials D1, D2, D3, D4 about said axis Y. In other words, the application elements 11 are implanted in at least three different angular positions around the main elongation axis Y, so that 'they adopt a three-dimensional arrangement on the body 12 not yet twisted (illustrated in Figures 2 to 5 ).

Ainsi, certains de ces éléments d'application s'étendent, à partir du corps 12 non vrillé, selon une première direction radiale D1, tandis que d'autres éléments s'étendent à partir ce corps 12 selon une deuxième direction radiale D2 distincte de la première direction radiale D1, tandis qu'encore d'autres éléments 11 s'étendent respectivement selon une troisième et une quatrième direction radiale D3, D4 distinctes. En d'autres termes, les éléments d'application 11 sont attachés au corps 12 en des points d'attache qui sont disposés sur le corps 12 de façon que lorsque le corps 12 est à l'état non vrillé, lesdits points d'attache appartiennent à au moins trois rayons distincts relativement à l'axe d'allongement principal Y. Une telle distribution tridimensionnelle des éléments d'application 11 sur et autour du corps 12 permet d'obtenir un effet de maquillage optimisé, qui combine les avantages des brosses à mascara torsadées classiques et ceux associés aux brosses moulées.
Avantageusement, les éléments d'application 11 sont disposées sur le corps 12, préalablement au torsadage de ce dernier, selon au moins quatre directions radiales distinctes D1, D2, D3, D4 équiréparties autour dudit axe d'allongement principal Y. Les éléments d'application s'étendent sensiblement perpendiculairement à l'axe Y.Thus, some of these application elements extend from the body 12 not twisted in a first radial direction D1, while other elements extend from the body 12 in a second radial direction D2 distinct from the first radial direction D1, while still other elements 11 extend respectively in a third and fourth radial direction D3, D4 distinct. In other words, the application elements 11 are attached to the body 12 at attachment points which are arranged on the body 12 so that when the body 12 is in the non-twisted state, said attachment points belong to at least three distinct rays relative to the main axis of elongation Y. Such a three-dimensional distribution of the application elements 11 on and around the body 12 provides an optimized makeup effect, which combines the advantages of the brushes classical twisted mascara and those associated with molded brushes.
Advantageously, the application elements 11 are disposed on the body 12, prior to the twisting thereof, in at least four distinct radial directions D1, D2, D3, D4 equidistributed around said main elongation axis Y. The elements of FIG. application extend substantially perpendicular to the Y axis.

Les éléments d'application 11 du premier organe d'application peuvent avoir un pas différent ou non le long de l'axe d'allongement principal Y de la tête applicatrice, le pas désignant l'écartement entre deux éléments d'application consécutifs d'une rangée, constituée par les éléments dépassant d'une direction radiale principale. En variante encore, le pas peut varier le long d'une rangée. Chaque rangée peut comporter un même nombre d'éléments d'application ou en variante, un nombre différent d'éléments d'application. Au sein d'une ou plusieurs rangées, les bases des éléments d'application peuvent être alignées ou disposées en quinconce.The applicator elements 11 of the first applicator member may have a different pitch or not along the main elongation axis Y of the applicator head, the pitch designating the spacing between two consecutive application elements of the applicator head. a row constituted by the elements protruding from a main radial direction. In another variant, the pitch may vary along a row. Each row may have the same number of application elements or, alternatively, a different number of application elements. Within one or more rows, the bases of the application elements may be aligned or arranged in staggered rows.

Dans les exemples illustrés, les éléments d'application 11 présentent une hauteur constante mais, dans des variantes non représentées, la hauteur des éléments d'application 8 peut varier, de façon monotone ou non, lorsque l'on se déplace le long de l'âme. La hauteur des éléments d'application peut être comprise entre 0,5 et 8 mm, étant de préférence égale à 4 mm. La largeur à la base des éléments d'application 11 est avantageusement comprise entre sensiblement 0,2 et 3 mm, de préférence entre sensiblement 0,3 et 1 mmIn the illustrated examples, the application elements 11 have a constant height but, in variants not shown, the height of the application elements 8 can vary, monotonically or not, as one moves along the surface. 'soul. The height of the application elements can be between 0.5 and 8 mm, preferably being 4 mm. The width at the base of the application elements 11 is advantageously between approximately 0.2 and 3 mm, preferably between approximately 0.3 and 1 mm.

Bien évidemment, l'invention n'est pas limitée à une structure particulière du (ou des) éléments d'application, ladite structure étant essentiellement dictée par la consistance du produit à appliquer, et les caractéristiques du maquillage recherchées.Obviously, the invention is not limited to a particular structure of the (or) application elements, said structure being essentially dictated by the consistency of the product to be applied, and the desired makeup characteristics.

Le degré de torsadage de l'âme 7 au niveau du premier organe d'application est par exemple compris entre 0 et 5 tours, notamment entre 1 et 3 tours. Par « vrillage du premier organe d'application », il faut comprendre une rotation de la section transversale du premier organe d'application autour de son axe longitudinal. Le degré de vrillage de l'organe d'application désigne l'angle dont a tourné la section. Le degré de torsadage de l'âme varie sur la longueur de cette dernière, il est moins vrillé autour du premier organe d'application qu'autour du deuxième organe d'application. Le degré de torsadage de l'âme étant maximal dans une portion de l'âme où il n'y a aucun organe d'application. Le degré de torsadage de l'âme 7 varie sur sa longueur, et en particulier augmente depuis son extrémité libre 13 vers son extrémité proximale retenue dans la tige 2. En effet, le premier organe d'application 5 est situé au niveau d'une extrémité distale 14 de la tête applicatrice 4, opposée à une extrémité proximale 15 de cette tête relativement à un axe longitudinal Y.The degree of twisting of the core 7 at the first applicator member is for example between 0 and 5 turns, especially between 1 and 3 turns. By "twisting the first applicator member", it is necessary to understand a rotation of the cross section of the first applicator member about its longitudinal axis. The degree of twisting of the applicator means the angle of which the section has turned. The degree of twisting of the core varies over the length of the latter, it is less twisted around the first applicator member than around the second applicator member. The degree of twisting of the core being maximal in a portion of the core where there is no application member. The degree of twisting of the core 7 varies along its length, and in particular increases from its free end 13 towards its proximal end retained in the rod 2. Indeed, the first applicator member 5 is located at a distal end 14 of the applicator head 4, opposite a proximal end 15 of this head relative to a longitudinal axis Y.

Le long de l'axe Y, on trouve successivement en partant de l'extrémité distale 14 de l'applicateur en direction de l'extrémité 2b de la tige où il est rattaché par son extrémité proximale 15 : le premier organe d'application 5, et ensuite le deuxième organe d'application 6. Il n'y a de préférence pas de recouvrement le long de l'axe Y, au niveau des branches 8 et 9 entre les deux organes d'application.Along the axis Y, one finds successively starting from the distal end 14 of the applicator towards the end 2b of the rod where it is attached by its proximal end 15: the first applicator member 5 and then the second applicator member 6. There is preferably no overlap along the Y axis, at the branches 8 and 9 between the two application members.

Comme cela est visible sur les figures 4a et 4b, au moins un élément d'application s'étend au niveau, voire au-delà d'une extrémité libre 13 de l'âme 7. Sur la figure 4a, au sein d'une rangée, il ya deux éléments d'application 11' qui dépassent de l'extrémité libre 13. En particulier, le long de l'axe Y, la base de ces éléments d'application 11' est située au-delà de l'extrémité libre 13. Ce sont ces éléments d'application 11' qui forment alors l'extrémité distale de l'applicateur 1. Dans l'exemple représenté, cette extrémité libre 13 est formée par le coude du fil métallique replié sur lui-même avant d'être torsadé. De préférence, une deuxième rangée diamétralement opposée à celle présentant les éléments 11' est configurée de la même manière. Cette configuration permet de masquer l'extrémité libre 13 de l'âme 7.As is visible on the Figures 4a and 4b at least one application element extends at or even beyond a free end 13 of the core 7. On the figure 4a , within a row, there are two application elements 11 'protruding from the free end 13. In particular, along the Y axis, the base of these elements 11 'is located beyond the free end 13. It is these application elements 11' which then form the distal end of the applicator 1. In the example shown, this free end 13 is formed by the elbow of the wire folded on itself before being twisted. Preferably, a second row diametrically opposed to that having the elements 11 'is configured in the same way. This configuration makes it possible to mask the free end 13 of the core 7.

En variante, Figure 4b, les éléments d'application 111, qui dépassent au delà de l'extrémité libre 13, sont agencés sur le pourtour extérieur du corps 12 pour présenter respectivement différentes positions angulaires relativement à l'axe Y. Ces différentes positions angulaires sont successives et permettent ainsi de présenter des éléments perpendiculaires à l'axe Y, et ou d'autres formant un angle aigu avec cet axe Y, et ou avantageusement au moins un élément 115 présentant un allongement sensiblement parallèle à l'axe Y. Dans l'exemple de la Figure 4b, chaque rangée comporte deux éléments 111' à 90° avec l'axe Y, trois autre éléments 112, 113 et 114 faisant respectivement chacun un angle d'environ 17°, 45° et 72°, et enfin un dernier élément 115 parallèle à l'axe Y.In a variant, Figure 4b , the application elements 111, which protrude beyond the free end 13, are arranged on the outer periphery of the body 12 to respectively present different angular positions relative to the Y axis. These different angular positions are successive and thus allow to present elements perpendicular to the axis Y, and or others forming an acute angle with this axis Y, and or advantageously at least one element 115 having an elongation substantially parallel to the axis Y. In the example of the Figure 4b each row comprises two elements 111 'at 90 ° with the axis Y, three other elements 112, 113 and 114 respectively making an angle of approximately 17 °, 45 ° and 72 ° respectively, and finally a last element 115 parallel to the Y axis.

L'âme 7 présente une portion vrillée dans le sens horaire lorsque l'on progresse de l'extrémité proximale 15, attachée à la tige, vers l'extrémité libre 13. En variante, cette portion vrillée peut aussi l'être dans le sens anti-horaire. En variante encore, le torsadage de la l'âme a lieu selon deux sens différents sur deux portions successives distinctes. Ces portions peuvent correspondre aux portions où sont respectivement retenus le premier et le deuxième organe d'application.The core 7 has a clockwise twisted portion when progressing from the proximal end 15, attached to the stem, towards the free end 13. Alternatively, this twisted portion may also be in the direction counterclockwise. In another variant, the twisting of the core takes place in two different directions on two distinct successive portions. These portions may correspond to the portions in which the first and second application members are respectively retained.

La longueur totale, le long de l'axe Y, de la tête applicatrice 4 est par exemple comprise entre 10 et 40 mm, de préférence entre 20 et 30 mm. De préférence, la portion de l'âme retenant le premier organe d'application représente moins de la moitié, voire moins du tiers, mieux moins d'un quart de cette longueur totale.The total length, along the Y axis, of the applicator head 4 is for example between 10 and 40 mm, preferably between 20 and 30 mm. Preferably, the portion of the core retaining the first applicator member is less than half, or even less than one third, better less than a quarter of this total length.

Du fait du torsadage de l'âme, on obtient le vrillage des organes d'application, et un foisonnement hélicoïdal à la fois des poils et des éléments d'application successivement le long de l'axe Y.Due to the twisting of the core, the twisting of the application members is obtained, and a helical expansion of both the bristles and the application elements successively along the Y axis.

L'invention n'est pas limitée à une orientation et/ou à un dimensionnement particulier des éléments d'application, lesquels peuvent adopter toutes formes souhaitées par l'homme du métier.The invention is not limited to a particular orientation and / or dimensioning of the application elements, which can adopt any shape desired by those skilled in the art.

Pour la réalisation d'une telle tête d'application, on insère entre les deux branches 8 et 9 le corps 12 dans son état non torsadé, ainsi que les paquets de poils 10, comme illustré à la figure 2. Dans les exemples illustrés aux figures 2, 4 et 5, les branches 8 et 9 sont initialement sensiblement droites, rectilignes et parallèles l'une à l'autre, tandis que le corps 12 est initialement non torsadé lorsqu'il est glissé entre lesdites branches. Un effort de torsion est ensuite exercé simultanément sur les deux branches, ce qui entraîne un torsadage en double hélice autour de l'axe Y, chaque hélice correspondant à l'une des branches. Le torsadage l'âme 7 entraîne simultanément la capture du corps 12 et des poils 10, et leur imparti leur foisonnement en hélice.For the production of such an applicator head, the body 12 is inserted between the two branches 8 and 9 in its non-twisted state, as are the bundles of bristles 10, as illustrated in FIG. figure 2 . In the examples illustrated in figures 2 , 4 and 5 , the branches 8 and 9 are initially substantially straight, straight and parallel to each other, while the body 12 is initially not twisted when slid between said branches. A twisting force is then exerted simultaneously on the two branches, resulting in a twisting helix around the Y axis, each helix corresponding to one of the branches. Twisting the core 7 simultaneously causes the capture of the body 12 and the bristles 10, and imparted their profusion propeller.

L'expression « comportant un » doit se comprendre comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.The expression "comprising one" must be understood as being synonymous with "having at least one" unless the contrary is specified.

L'expression « pour appliquer un produit sur les cils » doit se comprendre comme étant synonyme de « pour appliquer un produit sur les cils et/ou les sourcils », sauf si le contraire est spécifié.The phrase "to apply a product to the eyelashes" should be understood to mean "to apply a product to the eyelashes and / or the eyebrows" unless the contrary is specified.
