Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention se rapporte au domaine des applicateurs pour appliquer un produit fluide ou pâteux sur des fibres kératiniques telles que des cils ou des sourcils. De façon particulière les applicateurs visés par l'invention permettent d'appliquer un produit cosmétique, de maquillage ou de soin, sur les poils, cils ou sourcils.The invention relates to the field of applicators for applying a fluid or pasty product to keratin fibers such as eyelashes or eyebrows. In particular the applicators of the invention allow to apply a cosmetic product, makeup or care, on the hair, eyelashes or eyebrows.

Ces applicateurs comprennent essentiellement deux éléments : une âme de forme allongée sur laquelle est disposée au moins une rangée de dents ou picots.These applicators essentially comprise two elements: an elongated core on which is disposed at least one row of teeth or pins.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

On connaît de nombreux documents qui divulguent des produits de ce type qui visent avant tout à permettre de charger puis d'appliquer le produit idoine d'une manière aisée, simple et fiable, avec un résultat harmonieux. Dans le domaine considéré, on parle de fonction de charge, de fonction de séparation, de fonction de définition ou encore de fonction de recourbement qui doivent être réalisées par un tel applicateur.Many documents are known which disclose products of this type which are intended above all to make it possible to load and then apply the appropriate product in an easy, simple and reliable manner, with a harmonious result. In the field considered, we speak of charge function, separation function, definition function or bending function that must be performed by such an applicator.

Depuis un certain temps déjà on connait, par exemple par l'enseignement du document FR 2 505 633 , une brosse de maquillage présentant un support sur lequel sont fixés des poils, individuellement et régulièrement. Selon une caractéristique de cette invention, le support et les poils viennent d'injection d'un matériau moulable.For some time now we know, for example by teaching the document FR 2,505,633 , a makeup brush having a support on which are fixed bristles, individually and regularly. According to a characteristic of this invention, the support and the bristles come from injection molding material.

A titre illustratif encore, le document FR 2 850 549 divulgue une brosse applicatrice d'un produit sur des fibres kératiniques, comportant une âme supportant des poils dont une partie au moins s'étend de manière incurvée.By way of illustration, the document FR 2,850,549 discloses an applicator brush of a product on keratinous fibers, comprising a bristle-supporting core of which at least a portion extends in a curved manner.

On connaît encore par le document FR 2 902 984 un applicateur comportant une âme et au moins deux rangées de dents chacune orientées différemment vis-à-vis d'une face extérieure de l'âme. Ce type d'applicateur vise à améliorer l'application d'un produit notamment en termes de pénétration des dents entre les cils ou autres, de lissage du produit sur les cils et de séparation de ceux-ci.We still know from the document FR 2 902 984 an applicator having a core and at least two rows of teeth each oriented differently vis-à-vis an outer face of the soul. This type of applicator aims to improve the application of a product in particular in terms of penetration of the teeth between the eyelashes or other, smoothing the product on the eyelashes and separating them.

On connait également par la demande de brevet française EN 1056316 , publiée sous le numéro FR 2 963 215 , un dispositif applicateur permettant de régler et/ou de contrôler la souplesse des dents qui le constituent ; ce dispositif est ainsi constitué d'une âme et de plusieurs rangées de picots ; une première série de picots s'étend depuis l'âme jusqu'à une tige longitudinale tandis qu'une deuxième série de picots présente une première extrémité liée à la tige et une deuxième extrémité libre. Ce type d'applicateur permet de régler et/ou de contrôler la souplesse des dents (ou picots). Cependant un tel applicateur manque de souplesse radiale ; il est très peu déformable radialement ce qui est un inconvénient lorsqu'il s'agit de le faire traverser un élément annulaire appelé essoreur placé en sortie du conteneur du produit à appliquer. En effet la « charge « c'est-à-dire la quantité de produit en prise sur le dispositif n'est pas optimale et peut être insuffisante pour une bonne application sur les cils, avec un tel dispositif connu.We also know by the French patent application EN 1056316 published under number FR 2 963 215 an applicator device for adjusting and / or controlling the flexibility of the teeth which constitute it; this device thus consists of a core and several rows of pins; a first series of pins extends from the core to a longitudinal rod while a second series of pins has a first end connected to the rod and a second free end. This type of applicator makes it possible to adjust and / or control the flexibility of the teeth (or pins). However, such an applicator lacks radial flexibility; it is very little radially deformable which is a disadvantage when it comes to pass through an annular element called wiper placed at the outlet of the product container to be applied. Indeed the "load" that is to say the amount of product engaged on the device is not optimal and may be insufficient for a good application on the eyelashes, with such a known device.

Par ailleurs on connait par le document WO 2012/085398 un dispositif applicateur de produit fluide, monobloc, et qui, de façon caractéristique, comprend au moins une tige souple et flexible orientée longitudinalement et encastrée en au moins un premier et un deuxième points sur ladite âme longitudinale, de façon à ménager au moins une zone de flexion perpendiculaire à l'axe longitudinal XX. Vis-à-vis des dispositifs connus, cet applicateur représente une amélioration au niveau de la charge et de l'application du produit car la ou les tiges souples, encore appelées « arches », présentent une certaine mobilité, sont plus déformables et renferment donc une quantité variable de produit.Besides, we know from the document WO 2012/085398 a fluid applicator device, one-piece, and which, typically, comprises at least one flexible and flexible rod oriented longitudinally and recessed in at least a first and a second point on said longitudinal core, so as to provide at least one zone bending perpendicular to the longitudinal axis XX. With respect to known devices, this applicator represents an improvement in the load and the application of the product because the flexible rod or stems, also called "arches", have a certain mobility, are more deformable and therefore contain a variable amount of product.

Cet effet technique est très apprécié des utilisateurs ; mais au niveau de la fabrication et de la faisabilité de telles brosses, une limite technique parait difficile à franchir. En effet l'applicateur selon le document WO 2012/085398 est monobloc c'est-à-dire issu de moulage en une seule pièce.
Les documents USD682556 et FR2993151 décrivent un applicateur selon le préambule de la revendication 1.This technical effect is very popular with users; but in terms of the manufacture and the feasibility of such brushes, a technical limit seems difficult to overcome. Indeed the applicator according to the document WO 2012/085398 is monobloc that is to say, resulting from molding in one piece.
The documents USD682556 and FR2993151 describe an applicator according to the preamble of claim 1.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention vise à remédier aux inconvénients de l'état de la technique et notamment à proposer un applicateur doté de propriétés améliorées notamment au niveau de la modulation de la charge, et qui soit monobloc c'est-à-dire fabriqué en une seule étape de moulage tout en étant réalisable en bi-matière ou tri-matière.The invention aims to overcome the drawbacks of the state of the art and in particular to provide an applicator with improved properties especially at the level of the modulation of the load, and which is monobloc that is to say manufactured in a single molding step while being feasible in bi-material or tri-material.

La présente invention concerne un dispositif monobloc applicateur d'un produit fluide ou pâteux sur des fibres kératiniques, comprenant une âme s'étendant selon un axe longitudinal XX et au moins une tige souple encastrée en au moins un premier et un deuxième points sur l'âme longitudinale, ladite tige s'étendant sensiblement selon l'axe longitudinal XX, des picots étant prévus sur l'âme et/ou sur ladite au moins une tige.The present invention relates to a one-piece applicator device for a fluid or pasty product on keratinous fibers, comprising a core extending along a longitudinal axis XX and at least one flexible rod embedded in at least a first and a second point on the longitudinal core, said rod extending substantially along the longitudinal axis XX, pins being provided on the core and / or on said at least one rod.

Selon un premier aspect de l'invention, ladite âme est pourvue d'au moins une ouverture radialement traversante et ladite au moins une tige souple s'étend sensiblement dans un plan radial et présente selon sa longueur au moins une première et une deuxième courbures telles que ladite tige traverse sans contact ladite au moins une ouverture afin d'assurer sa mobilité dans un plan radial du dispositif.According to a first aspect of the invention, said core is provided with at least one radially through opening and said at least one flexible stem extends substantially in a radial plane and has along its length at least a first and a second curvature such said rod passes through said at least one opening without contact to ensure its mobility in a radial plane of the device.

Par « radialement traversante », on entend une ouverture de part en part de l'âme, qui s'étend globalement dans un plan radial du dispositif.By "radially through" means an opening from one side of the core, which extends generally in a radial plane of the device.

Dans la suite de ce texte, «tige» ou « arche» sera employé indifféremment. Comme il sera compris en référence au texte qui suit, la tige présente une forme caractéristique.In the rest of this text, "stem" or "arch" will be used indifferently. As will be understood with reference to the following text, the stem has a characteristic shape.

La mobilité de la ou des tiges est donc plus grande que dans l'art antérieur notamment par la présence de l'ouverture centrale dans laquelle la ou les tiges sont mobiles.The mobility of the rod or rods is therefore greater than in the prior art, in particular by the presence of the central opening in which the rod or rods are movable.

Selon l'invention, ladite au moins une tige présente au moins deux courbures de même orientation. Bien entendu ladite tige appartient à un plan radial.According to the invention, said at least one rod has at least two curvatures of the same orientation. Of course, said rod belongs to a radial plane.

Selon un mode caractéristique de l'invention, le dispositif comprend deux tiges souples s'étendant dans deux plans radiaux distincts. Les tiges souples se croisent au niveau de l'ouverture radialement traversante.According to a characteristic mode of the invention, the device comprises two flexible rods extending in two distinct radial planes. The flexible rods intersect at the radially through opening.

En outre, le dispositif peut comprendre au moins une tige additionnelle encastrée par ses deux extrémités au niveau de l'extrémité distale du dispositif. Une sorte de boucle est ainsi prévue à l'extrémité distale du dispositif, dont la fonction sera explicitée ci-après. L'extrémité distale est comprise comme l'extrémité libre du dispositif, opposée à l'extrémité proximale à laquelle est généralement fixé l'axe ou la poignée de maintien de l'applicateur.In addition, the device may comprise at least one additional rod embedded by its two ends at the distal end of the device. A kind of loop is thus provided at the distal end of the device, whose function will be explained below. The distal end is understood as the free end of the device, opposite the proximal end to which is generally attached the axis or the holding handle of the applicator.

De façon intéressante, la section transversale de l'âme peut être variable selon l'axe longitudinal XX.Interestingly, the cross section of the core may be variable along the longitudinal axis XX.

Selon un mode de réalisation de l'invention, le dispositif monobloc comprend au moins un ergot orienté radialement et apte à modifier la forme de l'ouverture si un effort axial est appliqué à l'extrémité distale du dispositif.According to one embodiment of the invention, the one-piece device comprises at least one radially oriented lug and adapted to modify the shape of the opening if an axial force is applied to the distal end of the device.

Conformément à un mode de réalisation de l'invention, l'une au moins desdites tiges présente une forme en S et s'étend sensiblement selon toute la longueur (XX) du dispositif.According to one embodiment of the invention, at least one of said rods has an S shape and extends substantially along the entire length (XX) of the device.

Selon un autre mode de réalisation de l'invention, le dispositif comprend une tige dont la forme est définie par une première courbure qui s'étend selon la longueur du dispositif, par une double courbure et par une liaison entre lesdites courbures disposée au niveau de ladite ouverture de l'âme. La première courbure et la double courbure appartiennent à un même plan radial. La forme complexe d'une telle tige est cependant moulable avec le reste du dispositif. L'intérêt de ce mode de réalisation réside en ce qu'il permet au moins deux types de maquillage différents, tel qu'il sera explicité ci-après en relation avec les modes de réalisation illustrés.According to another embodiment of the invention, the device comprises a rod whose shape is defined by a first curvature which extends along the length of the device, by a double curvature and by a connection between said curvatures arranged at the level of said opening of the soul. The first curvature and the double curvature belong to the same radial plane. The complex shape of such a rod is however moldable with the rest of the device. The advantage of this embodiment lies in that it allows at least two different types of makeup, as will be explained below in connection with the illustrated embodiments.

Par ailleurs conformément à ce mode de réalisation, l'élément de liaison présente un ergot orienté radialement et perpendiculairement au plan de la tige, ledit ergot étant apte à coopérer avec un bord de l'âme afin de maintenir la tige dans une position donnée.Moreover according to this embodiment, the connecting element has a lug oriented radially and perpendicular to the plane of the rod, said lug being adapted to cooperate with an edge of the core to maintain the rod in a given position.

En outre, selon un mode particulier de réalisation de l'invention, ladite au moins une tige présente trois courbures successives selon l'axe XX, de même orientation et séparées par deux points d'inflexion.In addition, according to a particular embodiment of the invention, said at least one rod has three successive curvatures along the axis XX, of the same orientation and separated by two points of inflection.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATIONDETAILED DESCRIPTION OF AN EMBODIMENT

La figure 1 illustre par une vue en perspective un premier mode de réalisation de l'invention selon lequel le dispositif monobloc, apte à appliquer un produit fluide ou pâteux sur des fibres kératiniques, comprend une âme 1 qui s'étend selon un axe longitudinal XX ; l'âme 1 présente une extrémité proximale 10 proche et coopérant avec une tige de préhension (non représentée), et une extrémité distale 11 libre. Au moins une tige souple 2 est en outre prévue, encastrée en au moins un premier et un deuxième points sur l'âme longitudinale 1. Les points d'encastrement se situent ici à proximité des extrémités, respectivement proximale et distale, de l'âme 1. L'encastrement s'entend au sens mécanique usuel c'est-à-dire comme une liaison sans degré de liberté.The figure 1 illustrates in perspective view a first embodiment of the invention according to which the one-piece device, capable of applying a fluid or pasty product to keratinous fibers, comprises a core 1 which extends along a longitudinal axis XX; the core 1 has a proximal end 10 close and cooperating with a gripping rod (not shown), and a distal end 11 free. At least one flexible rod 2 is further provided, embedded in at least first and second points on the longitudinal core 1. The embedding points are located near the ends, respectively proximal and distal, of the soul 1. The embedding is understood in the usual mechanical sense that is to say as a connection without degree of freedom.

La figure 1 montre par ailleurs des picots 3 prévus sur la ou les tiges 2 ainsi que sur l'âme 1. L'homme de métier déterminera la pertinence de la présence des picots 3 ; il déterminera en outre leur densité, leur orientation de façon plus ou moins empirique. La longueur du dispositif mesurée selon l'axe XX peut être comprise entre dix millimètres et trente millimètres, et son diamètre extérieur se situe entre cinq et quinze millimètres.The figure 1 also shows pins 3 provided on the rods 2 and 2 on the core 1. The skilled person will determine the relevance of the presence of the pins 3; it will also determine their density, their orientation more or less empirically. The length of the device measured along the axis XX may be between ten millimeters and thirty millimeters, and its outside diameter is between five and fifteen millimeters.

La tige flexible 2 s'étend dans un plan radial ou longitudinal, c'est-à-dire perpendiculaire à un plan transversal du dispositif. ; elle présente une forme spécifiquement étudiée afin d'en augmenter sa souplesse notamment dans le plan radial. Par ailleurs au moins une ouverture 4 est prévue dans l'âme 1. L'ouverture est traversante radialement c'est-à-dire qu'elle perce l'âme 1 de part en part et qu'elle est orientée selon un plan radial. La forme de l'ouverture est globalement allongée selon l'axe longitudinal XX. Elle est disposée afin de coopérer efficacement avec la ou les tiges 2 de forme spécifique.The flexible rod 2 extends in a radial or longitudinal plane, that is to say perpendicular to a transverse plane of the device. ; it has a form specifically designed to increase its flexibility especially in the radial plane. Furthermore, at least one opening 4 is provided in the core 1. The opening is through radially, that is to say it pierces the core 1 from one side to the other and is oriented in a radial plane . The shape of the opening is generally elongated along the longitudinal axis XX. It is arranged to cooperate effectively with the rod or rods 2 of specific shape.

Par « tige flexible » on entend au sens de l'invention un élément allongé selon l'axe XX, flexible et déplaçable essentiellement dans un plan radial.By "flexible rod" is meant in the sense of the invention an elongated element along the axis XX, flexible and essentially displaceable in a radial plane.

Selon le mode de réalisation de l'invention présenté sur la figure 1, ainsi que les figures 2 à 4, la tige 2 présente selon sa longueur, entre ses deux extrémités encastrées, une première 20 et une deuxième 21 courbures de même orientation ; la première courbure 20 et la deuxième courbure 21 sont donc orientées dans le même sens et elles se succèdent sur la longueur de la tige 2. La première et la deuxième courbures se rejoignent (ici sensiblement au milieu de la longueur de l'âme 1) au niveau de l'ouverture 4 prévue dans l'âme 1, en un point d'inflexion. A ce niveau, la tige 2 traverse sans contact l'ouverture 4. La figure 2 montre plus en détail cet arrangement caractéristique et intéressant.According to the embodiment of the invention presented on the figure 1 , as well as Figures 2 to 4 , the rod 2 has along its length, between its two recessed ends, a first 20 and a second 21 curvatures of the same orientation; the first curvature 20 and the second curvature 21 are thus oriented in the same direction and they follow each other along the length of the rod 2. The first and second curvatures meet (here substantially in the middle of the length of the web 1) at the opening 4 provided in the core 1, at a point of inflection. At this level, the rod 2 passes through the opening 4 without contact. figure 2 shows in more detail this characteristic and interesting arrangement.

Par ailleurs la figure 3 montre qu'une deuxième tige 2 telle que décrite ci-dessus est prévue, dans le même plan radial que la tige décrite ci-avant, mais disposée à 180° de celle-ci. Les deux courbures 20, 21 de la deuxième tige 2 se rejoignent au même niveau que les courbures de la première tige 2, c'est-à-dire dans l'ouverture 4 ; il n'y a pas contact entre la zone de jonction des courbures 20, 21 de la deuxième tige 2 et les parois de l'ouverture 4. Cet arrangement permet aux tiges 2 d'être mobiles dans leur plan radial, avec une amplitude importante, nettement plus importante que sans présence d'ouverture 4. L'ouverture 4 combinée à la forme et à l'orientation spécifique des tiges 2, permet donc une mobilité techniquement intéressante. En effet la mobilité des tiges 2 permet de charger aisément le dispositif en produit liquide ou pâteux. Cette mobilité permet en outre d'étaler ledit liquide de façon plus homogène car l'effort exercé sur les fibres kératiniques est lui-même plus homogène. Par ailleurs la mobilité et la flexibilité apportées par l'invention permettent un passage facilité à travers l'orifice et l'essoreur du contenant de produit fluide, à travers lequel l'applicateur passe un très grand nombre de fois, dans un sens de translation et dans l'autre.Moreover, figure 3 shows that a second rod 2 as described above is provided in the same radial plane as the rod described above, but disposed at 180 ° thereof. The two curvatures 20, 21 of the second rod 2 are join at the same level as the curvatures of the first rod 2, that is to say in the opening 4; there is no contact between the junction region of the curvatures 20, 21 of the second rod 2 and the walls of the opening 4. This arrangement allows the rods 2 to be movable in their radial plane, with a large amplitude , much larger than without the presence of opening 4. The opening 4 combined with the shape and the specific orientation of the rods 2, therefore allows a technically interesting mobility. Indeed, the mobility of the rods 2 makes it easy to load the device into a liquid or pasty product. This mobility also makes it possible to spread said liquid more homogeneously because the force exerted on the keratin fibers is itself more homogeneous. Furthermore, the mobility and flexibility provided by the invention allow a facilitated passage through the orifice and the wiper of the fluid container, through which the applicator passes a very large number of times, in a translational direction. and in the other.

La figure 4 montre un mode de réalisation de l'invention qui diffère de celui des figures précédentes par la présence d'une tige additionnelle 22 encastrée par ses deux extrémités au niveau de l'extrémité distale 11 de l'âme. Une forme circulaire est ainsi donnée à la tige additionnelle 22 ; préférentiellement la tige additionnelle 22 appartient au même plan radial que les deux tiges 2 bien que cette disposition ne soit pas obligatoire. Plusieurs tiges additionnelles de ce type peuvent être prévues sans sortir du cadre de l'invention, qui s'étendent dans des plans différents. De façon réaliste entre une et six tiges additionnelles peuvent être prévues.The figure 4 shows an embodiment of the invention which differs from that of the previous figures by the presence of an additional rod 22 embedded by its two ends at the distal end 11 of the core. A circular shape is thus given to the additional rod 22; preferably the additional rod 22 belongs to the same radial plane as the two rods 2 although this provision is not mandatory. Several additional rods of this type can be provided without departing from the scope of the invention, which extend in different planes. Realistically between one and six additional rods can be provided.

La figure 5 correspond à un deuxième mode de réalisation de l'invention qui diffère du premier mode par la présence de trois courbures 20, 21, 23 sur chaque tige 2, au lieu de deux. Cette vue de côté montre bien que les deux tiges 2 appartiennent à un même plan et que les courbures se rejoignent au niveau de l'âme 1. Cette figure ne montre pas la ou les ouvertures 4, dans l'âme 1. Chaque ouverture présente les caractéristiques mentionnées ci-dessus ainsi que leur arrangement vis-à-vis de la zone où se rejoignent les courbures des tiges 2. L'homme de métier choisit selon les dimensions du dispositif, selon les matières utilisées, le mode de réalisation le plus adapté.The figure 5 corresponds to a second embodiment of the invention which differs from the first mode by the presence of three curvatures 20, 21, 23 on each rod 2, instead of two. This side view shows that the two rods 2 belong to the same plane and that the curvatures meet at the level of the core 1. This figure does not show the opening or openings 4 in the core 1. Each opening presents the characteristics mentioned above and their arrangement vis-à-vis the area where the curvatures of the rods meet 2. The skilled person chooses according to the dimensions of the device, according to the materials used, the embodiment the most adapted.

La perspective de la figure 6 permet de voir la ou les ouvertures traversantes 4 prévues dans l'âme et aptes à coopérer avec les tiges 2, plus particulièrement avec les courbures 20, 21, 23 de ces tiges et avec leur zones de jonction. Ce mode de réalisation comprend donc des tiges ayant une souplesse plus importante que le premier mode de réalisation puisque l'ouverture 4 est plus importante. Ce mode de réalisation offre à l'utilisateur davantage de précision lors de l'application du produit sur les fibres kératiniques. En effet chaque sommet d'une ondulation étant dégagé c'est-à-dire éloigné des autres sommets, les picots situés dans cette zone permettent un travail plus précis (plus localisé) des bords extérieurs de la frange formée par les cils, ainsi que des petits cils inférieurs.The perspective of figure 6 allows to see the or through openings 4 provided in the core and adapted to cooperate with the rods 2, more particularly with the curvatures 20, 21, 23 of these rods and with their junction zones. This embodiment therefore comprises rods having greater flexibility than the first embodiment since the opening 4 is larger. This embodiment offers the user more precision when applying the product to the keratinous fibers. Indeed, each vertex of an undulation being clear, that is to say remote from the other vertices, the pins located in this zone allow a more precise (more localized) work of the outer edges of the fringe formed by the eyelashes, as well as lower eyelashes.

La figure 7 concerne un mode de réalisation proche de celui de la figure 6 mais qui prévoit une tige additionnelle 22 semblable à celle de la figure 4. Il s'agit ici de montrer que diverses combinaisons sont possibles sans sortir du cadre de l'invention.The figure 7 relates to an embodiment close to that of the figure 6 but which provides for an additional rod 22 similar to that of the figure 4 . This is to show that various combinations are possible without departing from the scope of the invention.

Les figures 8 à 10 illustrent un troisième mode de réalisation de l'invention selon lequel deux tiges sont présentes, chacune en forme de S. Comme dans les modes de réalisation précédents, les tiges 2 se rejoignent au niveau de l'ouverture 4 de l'âme 1. La figure 9, par la coupe selon AA de la figure 8, montre bien la première courbure 20 de chaque tige 2 ; cette figure montre en outre la présence de picots 3 à la fois sur l'âme 1 et sur les tiges 2. Cette présence n'est pas obligatoire. La vue de face donnée par la figure 10 montre notamment que les deux tiges 2 ici prévues appartiennent à deux plans radiaux différents faisant entre eux un angle α d'environ 60°. L'homme de métier choisira l'angle α selon le cas de figure envisagé. L'angle α est couramment compris entre environ 30° et 80°.The Figures 8 to 10 illustrate a third embodiment of the invention according to which two rods are present, each in S-shape. As in the previous embodiments, the rods 2 meet at the opening 4 of the core 1. figure 9 , by the cut according to AA of the figure 8 shows well the first curvature 20 of each rod 2; this figure also shows the presence of pins 3 on both the core 1 and the rods 2. This presence is not mandatory. The front view given by the figure 10 shows in particular that the two rods 2 here provided belong to two different radial planes forming between them an angle α of about 60 °. The skilled person will choose the angle α according to the case envisaged. The angle α is commonly between about 30 ° and 80 °.

Les figures 11 et 12 concernent un autre (quatrième) mode de réalisation de l'invention selon lequel deux tiges 2 sont prévues chacune en forme de S et chacune dans un plan radial donné. Les deux tiges se croisent bien entendu au niveau de l'ouverture 4 dans laquelle elles sont mobiles. La coupe transversale de la figure 12, au niveau de l'ouverture 4, permet de bien voir la zone de jonction des tiges 2 qui forment ici ensemble un élément mobile et souple.The Figures 11 and 12 relate to another (fourth) embodiment of the invention according to which two rods 2 are each provided in the form of S and each in a given radial plane. The two rods cross, of course, at the opening 4 in which they are movable. The cross section of the figure 12 , at the opening 4, makes it possible to clearly see the junction zone of the rods 2 which here together form a mobile and flexible element.

Les figures 13 à 15 montrent un autre (cinquième) mode de réalisation de l'invention selon lequel l'ensemble mobile ou tige présente une forme particulière définie par une première courbure 25 qui s'étend selon sensiblement toute la longueur du dispositif, et par une double courbure 26, 27 prévue dans un même plan radial mais dont la convexité est opposée à celle de la première courbure 25. La liaison entre la première courbure 25 et la double courbure 26, 27 est réalisée au niveau de l'ouverture 4 qui permet le déplacement de l'ensemble mobile dans son plan radial. La figure 14, qui est une vue à 90° de la figure 13, permet de voir l'ouverture 4 dans l'âme 1, au niveau de la zone de liaison des courbures 25 et 26, 27 de l'ensemble mobile ou tige 2. La figure 15 illustre en vue de face ce même mode de réalisation et permet de confirmer que l'ensemble mobile ou tige 2 ; 25, 26, 27 appartient bien à un même plan radial.The Figures 13 to 15 show another (fifth) embodiment of the invention according to which the moving assembly or rod has a particular shape defined by a first curvature 25 which extends along substantially the entire length of the device, and by a double curvature 26, 27 provided in the same radial plane but whose convexity is opposite that of the first curvature 25. The connection between the first curvature 25 and the double curvature 26, 27 is formed at the opening 4 which allows the displacement of the moving assembly in its radial plane. The figure 14 , which is a 90 ° view of the figure 13 , makes it possible to see the opening 4 in the core 1, at the level of the connection zone of the curvatures 25 and 26, 27 of the moving assembly or rod 2. The figure 15 illustrates in front view this same embodiment and confirms that the moving assembly or rod 2; 25, 26, 27 belongs to the same radial plane.

Selon le type de cils à traiter, un mode de réalisation particulier est préféré.Depending on the type of eyelash to be treated, a particular embodiment is preferred.

Les figures 16, 16A, 16B et 16C illustrent schématiquement une variante du cinquième mode de réalisation. En effet on voit sur ces figures que l'ensemble mobile ou tige 2 ; 25, 26, 27 comporte un ergot 7 orienté radialement et perpendiculairement à leur propre plan radial. L'ergot 7 est apte à coopérer avec un bord de l'âme 1 afin de maintenir la tige 2 ; 25, 26, 27 dans une position donnée. La figure 16 illustre l'ergot 7 en contact avec un bord de l'âme 1 tandis que la figure 16C illustre l'ergot 7 en contact avec un autre bord de l'âme 1. On constate entre ces deux positions une légère déformation de la tige 2, due à sa souplesse intrinsèque. On maintient ainsi la tige dans une position fixe, souhaitée, qui permet un travail plus panoramique, apte à étirer davantage le produit fluide. En appuyant légèrement et latéralement sur l'ergot 7, la géométrie des arches ou courbures 25, 26, 27 change de sorte qu'un travail différent du maquillage peut être opéré.The Figures 16, 16A, 16B and 16C schematically illustrate a variant of the fifth embodiment. Indeed we see in these figures that the moving assembly or rod 2; 25, 26, 27 has a lug 7 oriented radially and perpendicularly to their own radial plane. The lug 7 is adapted to cooperate with an edge of the core 1 in order to maintain the rod 2; 25, 26, 27 in a given position. The figure 16 illustrates the lug 7 in contact with an edge of the core 1 while the figure 16C illustrates the lug 7 in contact with another edge of the core 1. There is between these two positions a slight deformation of the rod 2, due to its intrinsic flexibility. This maintains the rod in a fixed position, desired, which allows a more panoramic work, able to further stretch the fluid. By pressing lightly and laterally on the pin 7, the geometry of the arches or curvatures 25, 26, 27 changes so that a different work of the makeup can be operated.

Un autre effet intéressant peut être obtenu avec le mode de réalisation illustré par les figures 17, 17A et 18, 18A. Selon ce mode de réalisation de l'invention, un ergot 5 est prévu sur la tige 2, orienté radialement et apte à modifier la forme de l'ouverture 4 dans l'âme 1. Les figures 17 et 17A montrent l'ergot 5 disposé sensiblement à une extrémité de l'ouverture 4 tandis que les figures 18 et 18A montrent l'ergot 5 placé vers l'autre extrémité de l'ouverture 4. Ainsi en appuyant sur la pointe du dispositif, en son extrémité distale 11, l'utilisateur modifie la forme de l'ouverture 4 comme visible sur les figures 17 et 18 ; ainsi que la courbure de la tige 2 comme illustré sur les figures 17A et 18A. Ce mode de réalisation permet d'avoir deux profils différents, et ainsi de réaliser deux types d'application sensiblement différents. Un point de non-retour permet de maintenir la position. C'est le passage de l'applicateur à travers le col du conteneur, dans le sens de sa rentrée dans le conteneur, qui permet de revenir à la position initiale (selon les figures 17 et 17A).Another interesting effect can be obtained with the embodiment illustrated by the Figures 17, 17A and 18, 18A . According to this embodiment of the invention, a lug 5 is provided on the rod 2, radially oriented and able to modify the shape of the opening 4 in the core 1. The Figures 17 and 17A show the lug 5 disposed substantially at one end of the opening 4 while the figures 18 and 18A show the lug 5 placed towards the other end of the opening 4. Thus by pressing the tip of the device, at its distal end 11, the user changes the shape of the opening 4 as visible on the Figures 17 and 18 ; as well as the curvature of the rod 2 as illustrated on the Figures 17A and 18A . This embodiment makes it possible to have two different profiles, and thus to produce two substantially different types of application. A point of no return makes it possible to maintain the position. It is the passage of the applicator through the neck of the container, in the sense of its return to the container, which allows to return to the initial position (according to the Figures 17 and 17A ).

En outre la particularité et les caractéristiques des tiges 2 (simples, doubles, présentant une ou plusieurs ondulations ou courbures) sont renforcées par la souplesse générale obtenue par le passage à travers la ou les ouvertures radialement traversantes 4. Ainsi l'utilisateur trouve davantage de confort et de précision lors du maquillage ; l'approche et le positionnement sur la base des cils sont facilités par la souplesse conférée à la ou les tiges 2 pourvue de picots 3.In addition, the particularity and the characteristics of the rods 2 (simple, double, having one or more undulations or curvatures) are reinforced by the general flexibility obtained by the passage through the radially through opening or openings 4. Thus the user finds more of comfort and precision during makeup; the approach and the positioning on the base of the eyelashes are facilitated by the flexibility conferred on the rod (s) 2 provided with pins 3.

Par ailleurs les tiges 2 n'étant pas fixées sur l'âme au niveau de la ou des ouvertures traversantes 4, elles sont très souples. L'amplitude du mouvement des tiges est intéressante en ce qu'elle offre de nouvelles fonctions pour le maquillage.Moreover, since the rods 2 are not fixed on the core at the level of the through opening (s) 4, they are very flexible. The range of movement of the stems is interesting in that it offers new functions for makeup.

Mais la présente invention présente cependant une âme centrale 1 continue sur sa longueur ; la section de l'âme centrale 1 présente une ou plusieurs ouvertures traversantes 4 pour le passage des tiges ou plus précisément pour le passage des zones de liaison entre les courbures des tiges 2. Le dispositif monobloc selon l'invention présente donc une structure suffisamment rigide pour passer sans déformation ni dommages à travers l'organe d'essorage habituellement prévu au niveau du col du contenant de fluide, et ce pour de très multiples passages.However, the present invention has a central core 1 continuous along its length; the section of the central core 1 has one or more through openings 4 for the passage of the rods or more precisely for the passage of the connecting zones between the curvatures of the rods 2. The monoblock device according to the invention therefore has a sufficiently rigid structure to pass without deformation or damage through the wiper member usually provided at the neck of the fluid container, and for very many passages.

Il est très intéressant de noter que le dispositif selon l'invention, contrairement à l'art antérieur, est venu de moulage en une seule pièce ; un gain de temps est ainsi réalisé en production. Une grande précision dimensionnelle est garantie, ainsi qu'une parfaite maîtrise de toutes les formes constitutives de l'applicateur selon l'invention. Les avantages apportés par l'invention sont donc considérables et les différents modes de réalisation permettent des utilisations variées, parfaitement adaptées à la fois au type de fibres kératiniques à traiter, à la nature du fluide à appliquer et au mode de maquillage souhaité par l'utilisateur.It is very interesting to note that the device according to the invention, unlike the prior art, came from molding in one piece; a saving of time is thus achieved in production. High dimensional accuracy is guarantee, as well as perfect control of all the constituent forms of the applicator according to the invention. The advantages provided by the invention are therefore considerable and the different embodiments allow a variety of uses, perfectly adapted both to the type of keratinous fibers to be treated, to the nature of the fluid to be applied and to the mode of makeup desired by the user.
