Description

La présente invention a pour objet un applicateur pour l'application de produit cosmétique, et en particulier destiné à être imprégné d'un produit démaquillant pour faciliter le démaquillage, et notamment le démaquillage des yeux, cils, sourcils et paupières.The subject of the present invention is an applicator for the application of a cosmetic product, and in particular intended to be impregnated with a make-up removal product to facilitate the removal of makeup, and in particular the removal of makeup from the eyes, eyelashes, eyebrows and eyelids.

Par « produit cosmétique », on entend un produit tel que défini dans la Directive 93/35/CEE du Conseil du 13 juin 1993."Cosmetic product" means a product as defined in Council Directive 93/35 / EEC of 13 June 1993.

Dans l'état de la technique, on connaît pour effectuer le démaquillage du visage l'utilisation de composition démaquillante. Ces compositions sont soit appliquées directement sur le visage et auquel cas elles sont retirées avec le maquillage au moyen de disques de coton, soit déposées sur un disque de coton ou une lingette non tissée de manière à appliquer la composition en frottant légèrement la peau de manière à démaquiller complètement le visage.In the state of the art, it is known to perform the make-up removal of the face the use of make-up remover composition. These compositions are either applied directly to the face and in which case they are removed with makeup by means of cotton discs, or deposited on a cotton disc or a nonwoven wipe so as to apply the composition by lightly rubbing the skin so that to completely remove the face.

Dans tous les cas, le démaquillage est coûteux car il nécessite l'utilisation de nombreux disques de coton ou de lingettes pour obtenir un démaquillage convenable, permettant d'enlever l'intégralité du maquillage et l'intégralité de la composition démaquillante dernièrement appliquée. Or ces disques de coton ou lingettes ne peuvent pas être réutilisés ensuite. En effet, les compositions de démaquillage et le maquillage retiré étant généralement liquides et visqueux, ils déforment et polluent de manière irréversible la structure aérée initiale du coton ou de la lingette. Par ailleurs, les disques de coton étant formés de fibres agglomérées, il n'est pas possible de les laver. Il en va de même des lingettes non tissées.In all cases, removing makeup is expensive because it requires the use of many cotton discs or wipes to obtain a proper make-up removing the entire makeup and the entire makeup remover recently applied. But these cotton discs or wipes can not be reused then. Indeed, the make-up removing compositions and the makeup removed being generally liquid and viscous, they deform and irreversibly pollute the initial aerated structure of the cotton or the wipe. Moreover, the cotton discs being formed of agglomerated fibers, it is not possible to wash them. The same is true of nonwoven wipes.

Par ailleurs, lorsqu'une utilisatrice cherche à démaquiller ses cils fortement gainés d'une couche de mascara sec, par exemple au moyen d'un coton imprégné d'une composition démaquillante, une grande partie de cette composition reste dans le coton sans servir au démaquillage, et enfin le mascara en partie solubilisé par la composition larguée, par exemple sous l'effet d'une pression sur ledit coton, est alors pris dans les mailles des fibres de coton tout en restant également solidaire des cils, ce qui aboutit à un arrachage de ces cils lorsque l'utilisatrice déplace légèrement ce coton le long de sa rangée de cils à démaquiller.Moreover, when a user seeks to remove her lashes heavily sheathed with a layer of dry mascara, for example by means of a cotton pad impregnated with a make-up remover composition, a large part of this composition remains in the cotton without being used for removing make-up, and finally the mascara partly solubilized by the released composition, for example under the effect of pressure on said cotton, is then caught in the mesh of the cotton fibers while also remaining attached to the eyelashes, which results in a tearing of these eyelashes when the user moves slightly this cotton along its row of eyelashes to remove makeup.

En particulier, on connaît du document US-3 742 242 un embout de démaquillage réalisé en mousse synthétique.In particular, document US-3,742,242 discloses a makeup remover made of synthetic foam.

Par ailleurs, du document US-4 140 409 est connu un dispositif de conditionnement d'une composition liquide contenue dans un récipient comportant une zone prédécoupée sur laquelle est retenu un organe d'application couvrant ladite portion. Le récipient et l'organe d'application sont prévus pour coopérer de manière à ce que le liquide soit distribué au travers de l'organe d'application lorsque le récipient est plié sur lui-même de manière à rompre la zone prédécoupée, et autoriser ainsi la sortie du produit hors du récipient.Furthermore, document US Pat. No. 4,140,409 discloses a device for conditioning a liquid composition contained in a container comprising a pre-cut zone on which an application member covering said portion is retained. The container and the applicator member are provided to cooperate so that the liquid is dispensed through the applicator member when the container is folded on itself so as to break the precut area, and allow thus the output of the product out of the container.

Cet organe d'application n'est pas ergonomique pour le démaquillage, car il ne permet pas de rendre la surface d'application proposée par l'organe d'application adaptable à l'application d'un produit sur des surfaces non planes et présentant à la fois des concavités et des convexités dans un environnement de petites dimensions, cette application devant en particulier se faire de manière très précise pour éviter d'amener du liquide au contact des yeux. En effet, le contour des yeux présente des concavités et des convexités dues notamment à la proximité de l'arête du nez, à la courbure des paupières et aux rangées de cils inférieures et supérieures qui ne sont pas de même longueur, ni de même implantation, relativement à l'ouverture de l'oeil. Or les compositions démaquillantes peuvent être irritantes pour l'oeil.This applicator member is not ergonomic for removing make-up, since it does not make it possible to make the application surface proposed by the applicator member adaptable to the application of a product on non-planar surfaces and presenting both concavities and convexities in a small environment, this application in particular to be done very precisely to avoid bringing liquid in contact with the eyes. Indeed, the contour of the eyes has concavities and convexities due in particular to the proximity of the edge of the nose, the curvature of the eyelids and rows of upper and lower lashes that are not the same length or the same implantation , relative to the opening of the eye. Or the makeup removing compositions may be irritating to the eye.

Dans l'état de la technique, il existe un besoin pour un nouvel applicateur facilitant le démaquillage, cet applicateur étant de préférence réutilisable et ou lavable.In the state of the art, there is a need for a new applicator facilitating makeup removal, this applicator is preferably reusable and or washable.

Il existe également un besoin pour un nouvel applicateur qui ait un taux de restitution élevé de la composition liquide dont il est imprégnée, pour que cette dernière soit utilisée efficacement pour obtenir le démaquillage souhaité, tout en proposant une surface d'application qui ne soit pas irritante et permette d'éviter la perte de cils au moment du démaquillage. En effet, la perte de cils étant rédhibitoire pour une consommatrice, son regard s'en trouvant modifié durablement, il existe un besoin pour un nouvel applicateur de produit démaquillant qui permette d'éviter cette perte de cils lors du démaquillage, tout en gardant la même gestuelle de démaquillage procédant par légers frottements des rangées de cils au moyen dudit applicateur.There is also a need for a new applicator that has a high restitution rate of the liquid composition of which it is impregnated, so that it is used effectively to obtain the desired makeup removal, while proposing an application surface that is not irritating and avoids the loss of eyelashes when removing makeup. Indeed, loss of eyelashes is unacceptable for a consumer, his eyes are changed durably, there is a need for a new makeup remover applicator which makes it possible to avoid this loss of eyelashes during makeup removal, while keeping the same make-up remover procedure by lightly rubbing the rows of eyelashes by means of said applicator.

L'invention a pour objet un applicateur comportant un support sur une face duquel est fixé un organe d'application élastiquement déformable présentant une surface d'application opposée au support, le support comportant un axe de pliure préférentiel de sorte que, en réponse à une contrainte de pliage exercée sur ledit support, l'organe d'application est déformé de manière à modifier la courbure transversale de la surface d'application observée transversalement audit axe, caractérisé en ce qu'il est configuré de sorte qu'en réponse à la contrainte de pliage exercée sur ledit support, la courbure longitudinale de la surface d'application observée axialement, le long dudit axe, est modifiée, une distance, mesurée orthogonalement à l'axe de pliure, entre une bordure du support et l'axe de pliure variant le long d'une portion au moins dudit axe de pliure.The subject of the invention is an applicator comprising a support on one face of which is fixed an elastically deformable applicator member having an application surface opposite to the support, the support comprising a preferential folding axis so that, in response to a bending stress exerted on said support, the applicator member is deformed so as to modify the transverse curvature of the application surface observed transversely to said axis, characterized in that it is configured so that in response to the bending stress exerted on said support, the longitudinal curvature of the application surface observed axially along said axis is modified, a distance, measured orthogonally to the fold axis, between a border of the support and the axis of fold varying along at least a portion of said fold axis.

De préférence, sous l'effet de forces de rappel élastiques générées par l'organe d'application et lorsque cesse la contrainte de pliage, la surface d'application reprend sa forme initiale.Preferably, under the effect of elastic restoring forces generated by the applicator member and when the bending stress ceases, the application surface returns to its original shape.

En particulier, dans sa forme initiale, hors contrainte, la surface d'application est plane, alors que sous l'effet d'une première contrainte de pliage donnée, exercée sur ledit support dans une direction opposée à la surface d'application, la surface d'application comporte au moins une section transversale convexe et au moins une section longitudinale concave.In particular, in its initial form, out of stress, the application surface is flat, whereas under the effect of a given first bending stress exerted on said support in a direction opposite to the application surface, the application surface has at least one convex cross-section and at least one concave longitudinal section.

Alternativement, dans sa forme initiale, hors contrainte, la surface d'application est plane, alors que sous l'effet d'une seconde contrainte de pliage, distincte de la première, la surface d'application comporte au moins une section transversale concave et au moins une section longitudinale convexe.Alternatively, in its initial form, out of stress, the application surface is flat, whereas under the effect of a second folding stress, distinct from the first, the application surface comprises at least one concave transverse section and at least one convex longitudinal section.

Lorsque la surface d'application présente une section transversale convexe, elle permet notamment le démaquillage des paupières et ou des cils inférieurs, alors que la formation d'une section transversale concave améliore le démaquillage des cils supérieurs, ces derniers pouvant être introduits dans la concavité formée. En effet, les faces respectivement inférieure et supérieure de cette rangée de cils peuvent être mise au contact simultanément avec la surface d'application lorsque cette dernière est concave.When the application surface has a convex cross-section, it allows in particular the removal of make-up of the eyelids and or eyelashes lower, while the formation of a concave cross section improves the makeup removal of upper lashes, the latter can be introduced into the formed concavity. Indeed, the respectively lower and upper faces of this row of eyelashes can be brought into contact simultaneously with the application surface when the latter is concave.

En particulier, la distance mesurée orthogonalement à l'axe de pliure et déterminée entre la bordure du support et ledit axe de pliure varie le long dudit axe de manière non monotone le long de l'axe de pliure.In particular, the distance measured orthogonal to the fold axis and determined between the edge of the support and said fold axis varies along said axis in a non-monotonic manner along the fold axis.

Par exemple, lorsqu'il est soumis à une contrainte de pliage, l'organe d'application est globalement moins comprimé au niveau d'une première section transversale qu'au niveau d'une seconde section transversale de cet organe d'application, la distance entre l'axe de pliure et l'intersection de la bordure du support avec cette première section transversale étant inférieure à la distance entre l'axe de pliure et l'intersection de la bordure du support avec la seconde section transversale.For example, when it is subjected to a bending stress, the applicator member is generally less compressed at a first transverse section than at a second cross section of this applicator member. distance between the fold axis and the intersection of the support border with this first cross section being less than the distance between the fold axis and the intersection of the support border with the second cross section.

La au moins une portion dudit axe de pliure peut représenter au moins 10% de la longueur de cet axe de pliure.The at least a portion of said fold axis may be at least 10% of the length of this fold axis.

Le support est divisé en deux parties par la ligne de pliure, et l'exercice d'une contrainte de pliage est telle qu'une première partie du support est entraînée en rotation autour de l'axe de pliure, par exemple de manière à effectuer une rotation comprise entre 90° et 180° depuis la position initiale dans laquelle les deux parties s'étendent dans un même plan.The support is divided into two parts by the fold line, and the exercise of a folding stress is such that a first part of the support is rotated about the fold axis, for example so as to effect a rotation between 90 ° and 180 ° from the initial position in which the two parts extend in the same plane.

Selon un mode de réalisation particulier de l'invention, le support est réalisé dans un matériau thermoplastique, et de préférence en polyéthylène. Par exemple, l'organe d'application peut être réalisé au moins en partie en mousse. En particulier, le support peut avoir une épaisseur comprise entre 0,3 et 2 mm, et l'organe d'application peut avoir une épaisseur comprise entre 5 et 15 mm, l'épaisseur de l'organe d'application pouvant notamment être choisie en fonction de la plus grande dimension de l'organe d'application mesurée transversalement à l'axe de pliure.According to a particular embodiment of the invention, the support is made of a thermoplastic material, and preferably polyethylene. For example, the applicator member may be at least partly made of foam. In particular, the support may have a thickness of between 0.3 and 2 mm, and the applicator member may have a thickness of between 5 and 15 mm, the thickness of the applicator member being particularly suitable for choosing according to of the largest dimension of the applicator member measured transversely to the fold axis.

Selon un mode de réalisation particulier, l'organe d'application est collé sur le support au moyen d'un adhésif. En variante, le support peut aussi être retenu mécaniquement dans un logement formé dans l'organe d'application. Il est alors par exemple maintenu au moyen d'un bloc disposé dans ce logement de manière à le repousser contre un pourtour intérieur délimitant une fenêtre d'accès audit logement.According to a particular embodiment, the applicator member is bonded to the support by means of an adhesive. Alternatively, the support may also be mechanically retained in a housing formed in the applicator member. It is then for example maintained by means of a block disposed in this housing so as to push against an inner periphery delimiting an access window to said housing.

En particulier, l'axe de pliure préférentiel est obtenu en prédécoupant le support de manière à réaliser des pointillés ou à amoindrir l'épaisseur du support le long dudit axe. Dans ce dernier cas, la prédécoupe est réalisée pour une partie dans l'épaisseur du support. Mais en variante, dans la mesure où le support est solidaire de l'organe d'application, l'axe de pliure peut également correspondre à une ligne de séparation totale entre les deux parties formant ensemble ledit support. Le cas échéant, la zone de moindre épaisseur du support formant l'axe de pliure peut aussi être obtenue lors de l'injection dudit support dans un moule adéquat par une charnière film par exemple.In particular, the preferred fold axis is obtained by pre-cutting the support so as to make dotted lines or to reduce the thickness of the support along said axis. In the latter case, the pre-cut is made for a part in the thickness of the support. But alternatively, insofar as the support is integral with the applicator member, the fold axis may also correspond to a total separation line between the two parts together forming said support. Where appropriate, the zone of smaller thickness of the support forming the fold axis can also be obtained during the injection of said support into a suitable mold by a film hinge for example.

En particulier, l'organe d'application présente un axe de symétrie sensiblement superposable à l'axe de pliure.In particular, the applicator member has an axis of symmetry substantially superimposable on the fold axis.

Dans les cas où l'organe d'application comporte un axe longitudinal, ce dernier peut être sensiblement superposable à l'axe de pliure.In cases where the applicator member comprises a longitudinal axis, the latter may be substantially superimposable on the fold axis.

De préférence, la surface d'application présente une superficie supérieure ou égale à celle de la face du support. Ainsi, quelle que soit la manière dont est plié l'applicateur, les arêtes définissant le pourtour de l'organe d'application sont proéminentes relativement aux arêtes du support.Preferably, the application surface has an area greater than or equal to that of the face of the support. Thus, regardless of how the applicator is bent, the edges defining the periphery of the applicator member are prominent relative to the edges of the support.

Enfin l'invention a également pour objet un procédé de fabrication d'un tel applicateur, ce procédé mettant en oeuvre les étapes suivantes :

  • production d'une paroi destinée à former le support,
  • enduction d'une face de cette paroi au moyen d'un adhésif,
  • application d'une couche d'un matériau destiné à former l'organe d'application, et
  • découpe du complexe formé par la paroi accolée à ladite couche de manière à individualiser des applicateurs, cette découpe étant concomitante d'une découpe partielle de la paroi de manière à former un axe de pliure préférentiel sur chaque applicateur.
Finally, the subject of the invention is also a method of manufacturing such an applicator, this method implementing the following steps:
  • production of a wall intended to form the support,
  • coating one side of this wall with an adhesive,
  • applying a layer of a material to form the application member, and
  • cutting the complex formed by the wall contiguous to said layer so as to individualize applicators, this cut being concomitant with a partial cut of the wall so as to form a preferential bending axis on each applicator.

In fine, une dernière étape de décorticage est réalisée. Elle consiste à enlever les parties découpées qui ne servent pas des applicateurs ainsi découpés.Finally, a final step of dehulling is carried out. It consists in removing the cut parts that do not serve applicators thus cut.

L'invention a également pour objet l'utilisation d'un applicateur selon l'invention pour l'application d'une composition de démaquillage et le démaquillage du visage, et encore plus particulièrement des yeux. En particulier, dans le cadre de cette utilisation, le dispositif selon l'invention est soumis à une première contrainte de pliage de manière à ce que la concavité de la surface d'application observée axialement le long de l'axe de pliure dans cette première position amène au moins une première portion de la surface d'application a être moins comprimée que les autres portions de l'organe d'application, alors qu'en exerçant une deuxième contrainte de pliage dans un sens opposé à la première contrainte, la concavité de la surface d'application observée axialement amène une deuxième portion distincte de la première portion a être moins comprimée que les autres portions, y compris la première portion.The invention also relates to the use of an applicator according to the invention for the application of a make-up removal composition and makeup removal of the face, and even more particularly the eyes. In particular, in the context of this use, the device according to the invention is subjected to a first folding stress so that the concavity of the application surface observed axially along the fold axis in this first position causes at least a first portion of the application surface to be less compressed than the other portions of the applicator member, while exerting a second bending stress in a direction opposite to the first constraint, the concavity the axially observed application surface causes a second distinct portion of the first portion to be less compressed than the other portions, including the first portion.

La Figure 1 montre un applicateur 1 selon l'invention comportant un support 2 sur une face 3 duquel est retenu un organe d'application 4.FIG. 1 shows an applicator 1 according to the invention comprising a support 2 on a face 3 of which an application member 4 is retained.

La face 3 du support 2 est sensiblement plane. De préférence, le support 2 se présente sous la forme d'une plaque comportant alors une deuxième face 5 opposée à la face 3. En particulier, l'épaisseur 6, Figure 2, de cette plaque formant support 2 est comprise entre 0,3 mm et 2 mm, et de préférence de l'ordre de 0,5 mm.The face 3 of the support 2 is substantially flat. Preferably, the support 2 is in the form of a plate then having a second face 5 opposite to the face 3. In particular, the thickness 6, FIG. 2, of this support plate 2 is between 0.3 mm and 2 mm, and preferably of the order of 0.5 mm.

L'organe d'application 4 présente une surface d'application 7, cette surface 7 étant sensiblement opposée à la deuxième face 5. En particulier, dans les modes de réalisations représentés, la surface d'application 7 est sensiblement plane lorsque le dispositif n'est soumis à aucune contrainte, et en particulier à aucune contrainte de pliage. Dans une position de stockage, hors contrainte, la surface d'application 7 est parallèle à la deuxième face 5. En particulier, l'épaisseur 8, Figure 2, de l'organe d'application 4 est comprise entre 5 mm et 15 mm, et de préférence de l'ordre de 12 mm.The applicator member 4 has an application surface 7, this surface 7 being substantially opposite to the second face 5. In particular, in the embodiments shown, the application surface 7 is substantially flat when the device is subject to no stress, and in particular to no folding stress. In a non-stressed storage position, the application surface 7 is parallel to the second face 5. In particular, the thickness 8, FIG. 2, of the applicator member 4 is between 5 mm and 15 mm. , and preferably of the order of 12 mm.

L'organe d'application 4 est réalisé dans un matériau élastiquement déformable, par exemple en mousse, notamment une mousse de polyuréthanne, de polyéthylène, de chlorure de polyvinyle, de polyéther, de polyester, de caoutchouc d'acrylonitrile butadiène, de caoutchouc de styrène butadiène, cette liste n'étant pas limitative. En particulier, cette mousse est à cellules ouvertes ou semi-ouvertes de manière à pouvoir s'imprégner de produit, en particulier de produit cosmétique, et de manière à pouvoir absorber le maquillage solubilisé par ledit produit cosmétique en vue de le retirer de la peau sur laquelle il avait été préalablement appliqué.The applicator member 4 is made of an elastically deformable material, for example a foam material, in particular a polyurethane, polyethylene, polyvinyl chloride, polyether, polyester, acrylonitrile butadiene rubber, rubber or polyurethane foam. styrene butadiene, this list not being limiting. In particular, this foam is open-celled or semi-open so as to be impregnated with product, in particular cosmetic product, and so as to absorb makeup solubilized by said cosmetic product to remove it from the skin on which it had been previously applied.

Alternativement, l'organe d'application 4 peut être réalisé en autre chose qu'une mousse, par exemple un feutre, une éponge ou un fritté d'une matière plastique ou minérale. L'organe d'application 4 peut présenter une structure monobloc ou multicouche, et comporter par exemple en surface un tissé, un non-tissé ou un flocage. La surface d'application 7 peut comporter ou non un flocage. L'organe d'application 4 peut contenir, le cas échéant, un agent bactéricide ou anti-fongique.Alternatively, the applicator member 4 can be made of anything other than a foam, for example a felt, a sponge or a sinter of a plastic or mineral material. The applicator member 4 may have a one-piece or multilayer structure, and for example comprise, on the surface, a woven fabric, a non-woven fabric or a flocking. The application surface 7 may or may not include flocking. The application member 4 may contain, where appropriate, a bactericidal or antifungal agent.

Le support 2 est de préférence réalisé dans un matériau thermoplastique comme par exemple un matériau polyoléfinique, tel que le polyéthylène, le polypropylène, le poly(chlorure de vinyle). En variante, il peut encore être réalisé en carton, ce dernier pouvant être plastifié ou vernis.The support 2 is preferably made of a thermoplastic material such as for example a polyolefin material, such as polyethylene, polypropylene, polyvinyl chloride. Alternatively, it can still be made of cardboard, the latter can be plasticized or varnished.

L'organe d'application 4 est dressé sur la face 3. Par exemple, Figures 1 à 9, l'applicateur 1 forme un cylindre dont la base est déterminée par le pourtour périphérique du support 2, la surface d'application 7 étant alors de dimension strictement identique à celle de la face 3.The applicator member 4 is erected on the face 3. For example, FIGS. 1 to 9, the applicator 1 forms a cylinder whose base is determined by the peripheral periphery of the support 2, the application surface 7 then being of dimension strictly identical to that of the face 3.

De manière à permettre une déformation de l'applicateur 1, obtenue manuellement, le support 2 comporte un axe de pliure préférentiel 9. Cet axe de pliure 9 se matérialise dans le support 2 par une ligne droite, continue ou discontinue, de moindre épaisseur formée dans ledit support 2. En particulier, l'amoindrissement de l'épaisseur 6 peut être partiel ou total. Cette ligne ou axe de pliure 9 sépare le support 2 en deux parties respectivement 10 et 11 de part et d'autre de cet axe 9. Dans une position de repos, hors contrainte, les parties 10 et 11 sont adjacentes et s'étendent dans un même plan.In order to allow a deformation of the applicator 1, obtained manually, the support 2 comprises a preferred fold axis 9. This fold axis 9 is materialized in the support 2 by a straight line, continuous or discontinuous, of smaller thickness formed in particular support 2. In particular, the decrease in thickness 6 may be partial or total. This line or fold axis 9 separates the support 2 in two parts respectively 10 and 11 on either side of this axis 9. In a rest position, out of stress, the parts 10 and 11 are adjacent and extend into the same plan.

L'organe d'application 4 est solidaire du support 2, et en particulier des parties 10 et 11. Il est par exemple fixé par collage au moyen d'un adhésif appliqué en couche mince sur la face 3 du support. En particulier, cet adhésif est apte à polymériser à température ambiante, ce collage étant obtenu au bout d'un temps donné, par exemple compris entre quelques minutes et 24 heures. Par exemple, une colle à base de polyuréthanne est appliquée à raison de 400g/m2. L'assemblage de l'organe d'application 4 et du support 2 peut également être obtenu à partir d'un matériau double face, ou par pulvérisation au pistolet d'une couche de colle par exemple de type néoprène, ou une dépose au rouleau d'une couche de colle chaude. Pour améliorer la force d'adhésion procurée par la colle, il peut être nécessaire d'exercer une contrainte en compression de l'organe d'application 4 sur le support 2 pour augmenter le contact. En variante, on peut également envisager une soudure de type miroir.The applicator member 4 is integral with the support 2, and in particular with the parts 10 and 11. It is for example fixed by gluing by means of an adhesive applied in a thin layer on the face 3 of the support. In particular, this adhesive is able to polymerize at room temperature, this bonding being obtained after a given time, for example between a few minutes and 24 hours. For example, a polyurethane glue is applied at a rate of 400 g / m 2 . The assembly of the applicator member 4 and the support 2 may also be obtained from a double-sided material, or by spraying with a glue layer of glue, for example of the neoprene type, or a roller deposit. a layer of hot glue. To improve the adhesion strength provided by the adhesive, it may be necessary to exert a compressive stress of the applicator member 4 on the support 2 to increase the contact. Alternatively, one can also consider a mirror type welding.

De fait, si une contrainte de pliage est exercée de manière à rapprocher les parties 10 et 11 l'une de l'autre par rotation autour de l'axe de pliure 9, quel que soit le sens de la rotation impliquée, l'organe d'application 4 sera également entraîné et contraint de se plier.In fact, if a folding constraint is exerted so as to bring the parts 10 and 11 to one another by rotation around the fold axis 9, whatever the direction of rotation involved, the member Application 4 will also be trained and forced to bend.

Figures 3a et 3b, la première contrainte de pliage F3 exercée sur l'applicateur 1 tend à accoler directement l'une à l'autre les parties 10 et 11 de manière à présenter en vis-à-vis les portions de la deuxième face 5 respectivement présentées par ces deux parties. Elle est exercée sur la surface d'application 7. En effet, la partie 10 est entraînée relativement à la partie 11 en rotation sur au moins 45°, de préférence sur au moins 90°, et de préférence jusqu'à la limite de déformation élastique de cet applicateur 1, en particulier sur 180° de rotation, si l'axe de pliure 9 et l'organe d'application 4 le permettent.FIGS. 3a and 3b, the first folding stress F3 exerted on the applicator 1 tends to attach the parts 10 and 11 directly to each other so as to face the portions of the second face 5 opposite each other. respectively presented by these two parties. It is exerted on the application surface 7. Indeed, the portion 10 is driven relative to the portion 11 in rotation over at least 45 °, preferably at least 90 °, and preferably up to the deformation limit elastic of this applicator 1, in particular over 180 ° of rotation, if the fold axis 9 and the applicator member 4 allow it.

Lorsqu'il est soumis à cette première contrainte de pliage F3, la surface d'application 7 présente une surface principalement convexe, l'organe d'application 4 étant contraint en extension, cette présentation de la surface d'application 7 étant notamment convenable pour être appliquée contre une paupière, et en particulier à proximité de l'implantation des cils sur cette paupière ou de l'implantation des cils sur le pourtour inférieur de l'oeil.When subjected to this first folding constraint F3, the application surface 7 has a predominantly convex surface, the applicator member 4 being constrained in extension, this presentation of the application surface 7 being in particular suitable for to be applied against an eyelid, and in particular near the implantation of the eyelashes on this eyelid or the implantation of the eyelashes on the lower periphery of the eye.

A contrario, Figures 4a et 4b, la seconde contrainte de pliage F4 exercée sur l'applicateur 1 tend à rapprocher les parties 10 et 11 de manière à compresser l'organe d'application entre elles, de telle sorte qu'elles présentent deux portions 12 et 13 de la surface d'application 7 respectivement en vis-à-vis l'une de l'autre, ces portions étant délimitées de part et d'autre d'un plan orthogonal à ladite surface d'application 7 et passant par l'axe de pliure 9. Dans ce cas, la partie 10 est entraînée relativement à la partie 11 en rotation sur au moins 45°, de préférence sur au moins 90°, et de préférence jusqu'à la limite de compression de l'organe d'application 4. En étant ainsi repliée sur elle-même, la surface d'application 7 présente une surface principalement concave, l'organe d'application 4 étant contraint en compression, les portions 12 et 13 sont présentées de manière à former une pince, notamment utile pour se placer de part et d'autre d'une rangée de cils.Conversely, FIGS. 4a and 4b, the second folding constraint F4 exerted on the applicator 1 tends to bring the parts 10 and 11 closer so as to compress the applicator member between them, so that they have two portions 12 and 13 of the application surface 7 respectively vis-à-vis one of the other, these portions being delimited by and else of a plane orthogonal to said application surface 7 and passing through the fold axis 9. In this case, the portion 10 is driven relative to the portion 11 in rotation over at least 45 °, preferably on at least 90 °, and preferably up to the compression limit of the applicator member 4. By being thus folded on itself, the application surface 7 has a predominantly concave surface, the body of 4 application is constrained in compression, the portions 12 and 13 are presented so as to form a clamp, especially useful to be placed on either side of a row of eyelashes.

La déformation de l'organe d'application 4, lorsqu'il est soumis à de telles contraintes de pliage, n'est pas la même en tout point, son taux de déformation dépendant des distances respectives de la zone considérée de cet organe 4 relativement à l'axe de pliure 9 et à la bordure périphérique 14 du support 2.The deformation of the applicator member 4, when subjected to such folding stresses, is not the same in every point, its rate of deformation depending on the respective distances of the zone considered from this member 4 relatively to the fold axis 9 and to the peripheral edge 14 of the support 2.

En effet, si l'on considère une ligne C formée par l'intersection entre la surface d'application 7 et un plan orthogonal à cette surface d'application 7 dans lequel s'étend l'axe de pliure 9, cette ligne C est droite dans la position initiale, dite « hors contrainte », dans la mesure où la surface d'application 7 est sensiblement plane. Or selon le mode de réalisation présenté Figures 1 à 7, cette ligne C est amenée à présenter au moins une concavité lorsque l'applicateur 1 est soumis à la première contrainte de pliage F3, et au moins une convexité lorsqu'il est soumis à la seconde contrainte de pliage F4.Indeed, if we consider a line C formed by the intersection between the application surface 7 and a plane orthogonal to this application surface 7 in which the fold axis 9 extends, this line C is right in the initial position, called "off stress", to the extent that the application surface 7 is substantially flat. However, according to the embodiment shown in FIGS. 1 to 7, this line C is caused to have at least one concavity when the applicator 1 is subjected to the first folding stress F3, and at least one convexity when it is subjected to the second folding constraint F4.

Selon ce mode de réalisation, lorsque la ligne C est concave, la surface d'application 7 est globalement convexe, alors que lorsque la ligne C est convexe, la surface d'application 7 est globalement concave. Ainsi, pour une contrainte de pliage donnée, l'applicateur 1 peut présenter une variation dans le taux de déformation de l'organe d'application 4, notamment le long de l'axe de pliure 9, où les variations sont les plus marquées. L'utilisatrice peut ainsi choisir la partie de l'organe d'application 4 à la fois la plus confortable et permettant une application nette sur la peau.According to this embodiment, when the line C is concave, the application surface 7 is generally convex, whereas when the line C is convex, the application surface 7 is generally concave. Thus, for a given bending stress, the applicator 1 may have a variation in the rate of deformation of the applicator member 4, particularly along the fold axis 9, where the variations are most marked. The user can thus choose the part of the application member 4 at the same time the most comfortable and allowing a clean application on the skin.

Figure 5, le pourtour périphérique 14 est de forme sensiblement ovoïde légèrement effilée au niveau de deux extrémités axiales opposées du support. En particulier, Figure 5, ces extrémités axiales du support correspondent aux extrémités axiales opposées 15 et 16 de l'axe de pliure 9.5, the circumferential periphery 14 is of substantially ovoidal shape slightly tapered at two opposite axial ends of the support. In particular, FIG. 5, these axial ends of the support correspond to the opposite axial ends 15 and 16 of the fold axis 9.

En particulier, si l'on considère, sur l'ensemble des vues de dessous des supports tels que 2, une droite 17 normale à l'axe de pliure 9, cette dernière coupe l'axe de pliure 9 en un premier point d'intersection 18, et coupe la bordure périphérique 14 en respectivement un deuxième et un troisième point d'intersection respectivement 19 et 20.In particular, if we consider, on all the bottom views of the supports such as 2, a straight line 17 normal to the fold axis 9, the latter intersects the fold axis 9 at a first point of intersection 18, and intersects the peripheral edge 14 respectively a second and a third intersection point respectively 19 and 20.

Si l'on déplace cette droite 17 le long de l'axe de pliure 9, sur au moins une portion de longueur non nulle de cet axe de pliure 9, on observe que la distance 21 entre le premier point d'intersection 18 et le deuxième point d'intersection 19 varie, et ce de manière non monotone le long de cet axe 9 dans les modes de réalisation représentés Figures 5 à 8. Cette distance 21 varie le long d'une portion de l'axe de pliure 9 représentant au moins 10% de la longueur de cet axe de pliure 9, et de préférence au moins 25%, et en particulier 100% de cette longueur de l'axe de pliure 9. La longueur de l'axe de pliure 9 correspond à la distance entre les extrémités axiales 15 et 16.If this line 17 is moved along the fold axis 9 over at least a non-zero length portion of this fold axis 9, it is observed that the distance 21 between the first intersection point 18 and the second intersection point 19 varies non-monotonically along this axis 9 in the embodiments shown in FIGS. 5 to 8. This distance 21 varies along a portion of the fold axis 9 representing at less than 10% of the length of this fold axis 9, and preferably at least 25%, and in particular 100% of this length of the fold axis 9. The length of the fold axis 9 corresponds to the distance between the axial ends 15 and 16.

En particulier, selon les modes de réalisation représentés Figures 5 à 8, les supports 2 présentent un axe de symétrie S sensiblement superposable à l'axe de pliure préférentiel 9.In particular, according to the embodiments shown in FIGS. 5 to 8, the supports 2 have an axis of symmetry S substantially superposable on the preferred fold axis 9.

Mais on ne sort pas du cadre de la présente invention, si en déplaçant la droite normale 17 le long de l'axe de pliure 9, on observe que la distance 21 varie le long de cet axe 9 différemment de la distance 22 entre le premier point d'intersection 18 et le troisième point d'intersection 20.But it is not beyond the scope of the present invention, if by moving the normal line 17 along the fold axis 9, it is observed that the distance 21 varies along this axis 9 differently from the distance 22 between the first intersection point 18 and the third intersection point 20.

Par « variant de manière non monotone » au sens de la présente invention, il faut comprendre que les distances respectivement 21 et 22 passent par au moins un extremum, par exemple un maximum. En particulier, Figure 5, la droite normale 17 représentée passe par ce maximum. A contrario, Figure 8, les distances respectivement 21 et 22 passent par un minimum. Les distances 21 et 22 peuvent encore passer par deux, voire plusieurs extrema.By "nonmonotone variant" in the sense of the present invention, it should be understood that the distances 21 and 22 respectively pass through at least one extremum, for example a maximum. In particular, Figure 5, the right Normal 17 represented by this maximum. In contrast, Figure 8, the distances respectively 21 and 22 pass through a minimum. Distances 21 and 22 can still go through two or more extrema.

En particulier, selon le mode de réalisation des Figures 5, 6 et 8, l'unique extremum est atteint dans une zone centrale de l'axe de pliure 9, alors que dans le mode de réalisation de la figure 7, cet extremum est atteint à distance de cette zone centrale, conférant de fait une forme de poire à ce pourtour périphérique 14.In particular, according to the embodiment of Figures 5, 6 and 8, the single extremum is reached in a central zone of the fold axis 9, while in the embodiment of Figure 7, this extremum is reached away from this central zone, conferring a pear-shaped shape to this peripheral periphery 14.

Cet optimum peut présenter une forme pointue, notamment triangulaire, ou arrondie, notamment circulaire ou ogivale.This optimum may have a pointed shape, in particular triangular, or rounded, in particular circular or ogival.

Par ailleurs, on ne sort pas du cadre de la présente invention lorsqu'en déplaçant la droite normale 17 le long de l'axe de pliure 9, on observe, Figure 9, que la distance 21 varie de manière monotone en particulier linéaire le long de cet axe 9, alors que la distance 22 peut elle-même varier de manière monotone et en particulier non linéaire, par exemple asymptotique, le long de ce même axe 9.Furthermore, it is not beyond the scope of the present invention when, by moving the normal line 17 along the fold axis 9, it is observed, FIG. 9, that the distance 21 varies monotonically, in particular linear along the of this axis 9, while the distance 22 may itself vary monotonously and in particular non-linear, for example asymptotic, along this same axis 9.

Selon une variante non représentée, la surface d'application 7 pourrait être concave ou convexe dans la position initiale « hors contrainte » et retrouver une surface d'application plane sous l'exercice d'une contrainte de pliage.According to a variant not shown, the application surface 7 could be concave or convex in the initial position "out of stress" and find a flat application surface under the exercise of a folding stress.

Selon une autre variante non représentée, l'applicateur 1 peut être recouvert sur ses deux faces respectivement 3 et 5 d'organes d'application tels que 4, multipliant ainsi par deux les surfaces d'application telles que 7, dont la courbure, observée transversalement et longitudinalement relativement à l'axe de pliure préférentiel 9, peut être respectivement modifiée en fonction de contraintes de pliage exercées sur ledit applicateur 1. Par exemple, l'applicateur 1 présente un plan de symétrie dans lequel s'étend par exemple le support 2.According to another variant not shown, the applicator 1 can be covered on its two faces respectively 3 and 5 of application members such as 4, thus multiplying by two the application surfaces such as 7, whose curvature, observed transversely and longitudinally relative to the preferred fold axis 9, can be respectively modified according to bending stresses exerted on said applicator 1. For example, the applicator 1 has a plane of symmetry in which extends for example the support 2.

Selon une variante de réalisation, notamment représentée aux figures 10 et 12, la surface d'application 7 peut être de dimension supérieure à celle des faces 3 et respectivement 5 du support 2. Selon ce mode de réalisation particulier, l'organe d'application 4 forme un bloc cylindrique, les surfaces 7 et 23 étant identiques. Le support 2 est alors fixé de manière à être centré sur la surface d'accrochage 23, opposée à la surface d'application 7 de l'organe d'application 4. Ainsi, quelque soit la manière dont est manipulé l'applicateur 1, le support 2 ne présente pas d'arête risquant d'être appliquée contre la peau, ce dernier étant de faible épaisseur 6.According to an alternative embodiment, in particular represented in FIGS. 10 and 12, the application surface 7 may be of greater dimension than that of the faces 3 and 5 of the support 2. According to this particular embodiment, the application member 4 forms a cylindrical block, the surfaces 7 and 23 being identical. The support 2 is then fixed so as to be centered on the hooking surface 23, opposite to the application surface 7 of the applicator member 4. Thus, whatever the way the applicator 1 is handled, the support 2 has no edge that may be applied against the skin, the latter being thin.

A contrario, selon le mode de réalisation de la Figure 11, la surface d'accrochage 23 est identique à celle de la face 3 du support 2, alors que la surface d'application 7 est plus grande, le pourtour 24 de l'organe d'application 4 présente alors des pans inclinés relativement au plan dans lequel s'étend la surface d'application 7. De plus, en variante dans le mode de réalisation représenté Figure 11, l'épaisseur 6 du support 2 est variable de manière à former un bourrelet annulaire 25 dépassant de la deuxième face 5 le long du pourtour périphérique 14.In contrast, according to the embodiment of FIG. 11, the hooking surface 23 is identical to that of the face 3 of the support 2, whereas the application surface 7 is larger, the periphery 24 of the body application 4 then has slopes inclined relative to the plane in which the application surface 7 extends. In addition, alternatively in the embodiment shown in Figure 11, the thickness 6 of the support 2 is variable so as to forming an annular bead 25 protruding from the second face 5 along peripheral periphery 14.

En variante encore, comme représenté aux Figures 13 et 14, le pourtour périphérique 14 du support 2 peut présenter des indentations 26 vers l'intérieur de manière à faciliter la préhension manuelle d'un tel applicateur 1. De préférence, de part et d'autre de la ligne de pliure 9, il présente au moins une première indentation pour recevoir le pouce et de préférence au moins deux indentations juxtaposées en vis-à-vis pour recevoir les autres doigts de la main. Cette disposition est notamment utile lorsque l'applicateur 1 est tenu dans une seule main.In another variant, as shown in FIGS. 13 and 14, the peripheral periphery 14 of the support 2 may have indentations 26 inwards so as to facilitate the manual gripping of such an applicator 1. Preferably, on the other hand, other of the fold line 9, it has at least a first indentation to receive the thumb and preferably at least two indentations juxtaposed vis-à-vis to receive the other fingers of the hand. This provision is particularly useful when the applicator 1 is held in one hand.

En variante, s'il n'est pas souhaitable de coller le support 2 à l'organe d'application 4 par exemple pour des problèmes de solubilisation de la colle avec le produit qui y sera imprégné, il est proposé dans le mode de réalisation représenté figure 15 de réaliser l'organe d'application 4 de telle sorte qu'il comporte un logement intérieur 27, ce logement débouchant via une ouverture 28 au niveau de la surface d'accrochage 23 opposée à la surface d'application 7.Alternatively, if it is undesirable to bond the support 2 to the applicator member 4, for example for problems of solubilization of the adhesive with the product which will be impregnated therein, it is proposed in the embodiment FIG. 15 shows the embodiment of the applicator member 4 so that it has an internal housing 27, this housing opening via an opening 28 at the attachment surface 23 opposite to the application surface 7.

Ce logement 27 peut être de dimension adaptée à l'insertion du support 2 par déformation élastique du pourtour 29 de l'ouverture 28. Le support 2 est alors retenu mécaniquement contre ce pourtour 29 pour être maintenu à l'intérieur du logement 27 solidaire dudit organe d'application 4.This housing 27 may be of suitable size for the insertion of the support 2 by elastic deformation of the periphery 29 of the opening 28. The support 2 is then mechanically retained against this periphery 29 to be maintained within the housing 27 secured to said applicator member 4.

Dans ce mode de réalisation, il est préférable de réaliser l'organe d'application 4 dans un matériau dont le toucher est très apprécié, et de remplir le logement 27, ici beaucoup plus grand avec un bloc élastiquement déformable 30. Ce bloc 30 permet de repousser le support 2 contre le pourtour 29.In this embodiment, it is preferable to make the applicator member 4 in a material whose feel is very appreciated, and to fill the housing 27, here much larger with an elastically deformable block 30. This block 30 allows to push the support 2 against the periphery 29.

Par exemple, et notamment selon ce mode de réalisation, le support 2 peut alors être obtenu d'injection, la ligne de pliure 9 correspondant à une charnière film formée dans ledit support au moment de l'injection. En particulier, la charnière film formée est prévue pour tolérer une rotation sur plus de 340°, et de préférence de 360° de la première partie 10 relativement à la deuxième partie 11.For example, and particularly according to this embodiment, the support 2 can then be obtained by injection, the fold line 9 corresponding to a film hinge formed in said support at the time of injection. In particular, the formed film hinge is provided to tolerate a rotation over 340 °, and preferably 360 ° of the first portion 10 relative to the second portion 11.

Alternativement, et notamment pour la réalisation des applicateurs tels que ceux représentés Figure 1 à 14, on colle une couche d'un matériau destiné à former l'organe d'application 4 sur une couche d'un matériau destiné à former le support 2. Ensuite, lorsque cet ensemble bicouche est solidifié, et que la colle a en particulier le cas échéant polymérisé, on découpe des applicateurs aux contours désirés selon l'invention à l'emporte pièce. Lors de cette étape de découpe, ladite ligne de pliure 9 est de préférence simultanément réalisée dans chacun des applicateurs tels que 1.Alternatively, and particularly for producing the applicators such as those shown in FIGS. 1 to 14, a layer of a material intended to form the applicator member 4 is bonded to a layer of a material intended to form the support 2. Then, when the bilayer assembly is solidified, and the glue has in particular optionally polymerized, cutters applicators to the desired contours according to the invention to the punch. During this cutting step, said fold line 9 is preferably simultaneously made in each of the applicators such as 1.

L'utilisatrice qui est équipée d'un tel applicateur 1, l'imprègne d'une composition démaquillante. Le support 2 étant de préférence imperméable au produit liquide, les doigts de l'utilisatrice ne sont pas mouillés par cette imprégnation. Ensuite, elle exerce manuellement la seconde contrainte de pliage sur l'applicateur 1, par exemple selon la force F4, et place la rangée supérieure de cils maquillés de mascara dans la concavité ainsi présentée par la surface d'application 7. Elle peut ainsi bien imprégner le mascara de composition démaquillante, et donc le dissoudre rapidement, le frottement léger des cils permettant de retirer le mascara sans exercer de contraintes trop fortes sur les cils risquant de les faire tomber. Lorsque les cils sont ainsi démaquillés, le pourtour périphérique 14 de l'organe d'application 4 est maculé par le mascara qui a été solubilisé via la composition démaquillante.The user who is equipped with such an applicator 1 impregnates it with a makeup remover composition. Since the support 2 is preferably impervious to the liquid product, the fingers of the user are not wetted by this impregnation. Then, it manually exerts the second folding constraint on the applicator 1, for example according to the force F4, and places the upper row of eyelashes made of mascara in the concavity thus presented by the application surface 7. It can thus well impregnating the mascara with makeup remover composition, and thus dissolve it quickly, the light friction of the eyelashes allowing to remove the mascara without exerting too much stress on the eyelashes likely to make them fall. When the eyelashes are thus removed, the peripheral periphery 14 of the applicator member 4 is stained by the mascara which has been solubilized via the makeup removal composition.

Ensuite pour démaquiller la paupière et la rangée inférieure de cils, tout en gardant l'applicateur 1 dans la main, l'utilisatrice lui applique la première contrainte de pliage F3, de manière à amener la surface d'application 7 à présenter une convexité. Etant donné que l'applicateur 1 est tenu au niveau du pourtour périphérique, la zone maculée de cette surface d'application 7 est éloignée d'une zone centrale de l'organe d'application s'étendant le long de l'axe de pliure 9.Then to remove the eyelid and the lower row of eyelashes, while keeping the applicator 1 in the hand, the user applies the first folding stress F3, so as to cause the application surface 7 to have a convexity. Since the applicator 1 is held at the periphery, the spotted area of this application surface 7 is moved away from a central area of the applicator member extending along the fold axis. 9.

Etant donné la convexité conférée à la surface d'application 7, la zone centrale peut donc être appliquée sans appliquer la zone maculée sur la paupière. Par ailleurs, dans cette position l'organe d'application 4 est comprimé dans cette zone centrale, la surface d'application 7 propose alors localement moins de souplesse mais une plus grande précision d'application de la composition, ce qui permet notamment de retirer la ligne de rehaussement du contour de l'oeil.Given the convexity imparted to the application surface 7, the central zone can therefore be applied without applying the spotted area on the eyelid. Furthermore, in this position the applicator member 4 is compressed in this central zone, the application surface 7 then locally offers less flexibility but a greater accuracy of application of the composition, which makes it possible in particular to remove the line of enhancement of the contour of the eye.

Dans le cas où l'organe d'application 4 est réalisé en mousse, après avoir démaquillé un oeil, l'utilisatrice peut rincer l'applicateur sous l'eau de manière à évacuer de la surface d'application 7 les produits de maquillage qui ont été retirés du premier oeil, et imprégner à nouveau ledit applicateur 1 pour démaquiller le deuxième oeil. Dans la mesure où l'organe d'application 4 peut être rincé après cette opération de démaquillage, le même applicateur peut être réutilisé plusieurs fois, jusqu'à ce qu'il soit usagé.In the case where the application member 4 is made of foam, after removing an eye makeup, the user can rinse the applicator under water so as to evacuate the application surface 7 makeup products that have been removed from the first eye, and again impregnate said applicator 1 to remove make-up of the second eye. Insofar as the application member 4 can be rinsed after this makeup removing operation, the same applicator can be reused several times, until it is used.

En variante de réalisation, l'organe d'application 4 peut être préimprégné d'une composition démaquillante, sous forme sèche ou humide, l'applicateur étant alors conditionné dans un emballage individuel le protégeant des contaminations extérieures. Dans le cas où la composition démaquillante imprégnée est sous forme sèche, l'utilisatrice est alors invitée à humidifier l'organe d'application avant de se l'appliquer.As an alternative embodiment, the applicator member 4 may be preimpregnated with a makeup-removing composition, in dry or wet form, the applicator then being packaged in an individual packaging protecting it against external contaminations. In the case where the impregnated makeup remover composition is in dry form, the user is then invited to moisten the applicator member before applying it.

Dans toute la description, l'expression « comportant un » doit être considérée comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.Throughout the description, the phrase "having one" should be considered synonymous with "having at least one", unless the opposite is specified.
