Abstract

The applicator consists of a moulded plastic core (4) with a series of supple radiating teeth (14, 15, 16, 17) in lengthwise rows. The teeth, which have a polygonal and preferably rectangular cross-section, are grouped in pairs (140, 150) with gaps (11) between them to hold a volume of the product to be applied. The gaps between the teeth in each pair broaden to 0.4 mm towards the tips of the teeth, and there are larger gaps of some 0.8 mm between the pairs.

La présente invention se rapporte au domaine technique général des dispositifs d'application de produits, en particulier de produits cosmétiques, sur des phanères, et en particulier des phanères filiformes et kératinisés tels que les cils ou les sourcils.The present invention relates to the general technical field of devices for applying products, in particular cosmetic products, to superficial body growths, and in particular filiform and keratinized integuments such as eyelashes or eyebrows.

La présente invention concerne un instrument pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils comprenant une âme s'étendant selon une direction axiale ainsi qu'au moins des première, seconde, troisième et quatrième excroissances faisant saillie à partir de l'âme.The present invention relates to an instrument for applying a liquid or semi-liquid product to the eyelashes or eyebrows comprising a core extending in an axial direction and at least first, second, third and fourth protuberances projecting from blade.

Dans son application préférentielle, l'instrument conforme à l'invention constitue un applicateur à mascara pour les cils, destiné à prélever une quantité de mascara dans un récipient, et à transporter cette quantité jusqu'aux cils pour la déposer sur ce dernier.In its preferred application, the instrument according to the invention is a mascara applicator for eyelashes, intended to collect a quantity of mascara in a container, and to carry this amount to the eyelashes to deposit it on the latter.

On connaît déjà des applicateurs à mascara se présentant sous la forme de brosses. De telles brosses comprennent classiquement un organe de préhension, pouvant faire office de bouchon pour un récipient contenant le mascara à appliquer, ainsi qu'une tige s'étendant à partir de l'organe de préhension entre une extrémité proximale et une extrémité distale.Mascara applicators are already known in the form of brushes. Such brushes conventionally comprise a gripping member, which can act as a stopper for a container containing the mascara to be applied, and a rod extending from the gripping member between a proximal end and a distal end.

Une multitude de poils s'étendent radialement à partir de la tige, au niveau de l'extrémité distale de cette dernière, formant ainsi une tête d'application.A multitude of bristles extend radially from the stem at the distal end thereof, thereby forming an application head.

Ces brosses de l'art antérieur sont destinées à être utilisées de la façon suivante.These brushes of the prior art are intended to be used in the following manner.

L'utilisateur trempe ladite brosse dans un récipient contenant du mascara, ce qui a pour effet d'enduire partiellement les poils et la tige de mascara. L'utilisateur effectue ensuite une action de brossage des cils à l'aide de la brosse, ce qui a pour effet de transférer du mascara de la brosse vers et sur les cils.The user soaks said brush in a container containing mascara, which has the effect of partially coating the hairs and the mascara rod. The user then performs an action of brushing the eyelashes using the brush, which has the effect of transferring mascara from the brush to and on the eyelashes.

Ces brosses à mascara connues présentent cependant un certain nombre d'inconvénients.These known mascara brushes, however, have a number of disadvantages.

En premier lieu, ces brosses de l'art antérieur ne permettent généralement pas de contrôler la quantité de mascara qu'elles collectent dans le récipient.In the first place, these brushes of the prior art generally do not allow to control the amount of mascara they collect in the container.

Dans certains cas, la brosse ne permet ainsi pas de collecter une quantité suffisante de mascara, de sorte que l'utilisateur est contraint de multiplier les trempages de la brosse dans le récipient, ce qui s'avère contraignant et augmente les risques de pollution, voire de contamination, du stock de mascara contenu dans le récipient. De plus, le brossage des cils avec une brosse insuffisamment chargée en mascara peut être, par les frottements qu'il induit, particulièrement désagréable, voire même douloureux.In some cases, the brush does not allow to collect a sufficient amount of mascara, so that the user is forced to multiply the dipping of the brush in the container, which is restrictive and increases the risk of pollution, even of contamination, of the mascara stock contained in the container. In addition, the brushing of the eyelashes with a brush insufficiently loaded with mascara may be, by the friction it induces, particularly unpleasant or even painful.

Dans d'autres cas, en particulier lorsque le mascara est très visqueux ou épais, la brosse, après qu'elle a été plongée dans le réservoir, peut se trouver surchargée en mascara. Cela signifie que la brosse va transporter jusqu'aux cils une quantité beaucoup trop importante de mascara en regard de la surface de cils à couvrir. Cela est susceptible d'engendrer un mauvais résultat de maquillage, lorsqu'une grande partie de cette surcharge de mascara est transférée sur les cils, formant des agglomérats inesthétiques avec et sur ces derniers. De plus, quand bien même l'ensemble de la surcharge de mascara n'est pas intégralement transférée aux cils, le mascara non utilisé, resté sur la brosse, est réintroduit dans le stock de mascara, au sein du récipient, ce qui augmente le risque de souillure et de contamination de ce dernier. Ce reliquat de mascara resté sur la brosse a tendance de surcroît à sécher sur cette dernière, ce qui est susceptible à la longue d'affecter les qualités d'application de la brosse et de dégrader le stock de mascara contenu dans le récipient, par mélange du stock avec des particules de mascara séchées.In other cases, particularly when the mascara is very viscous or thick, the brush, after it has been immersed in the tank, may be overloaded with mascara. This means that the brush will carry to the eyelashes a much too much amount of mascara next to the surface of eyelashes to cover. This is likely to cause a poor makeup result, when a large part of this overload of mascara is transferred to the eyelashes, forming unsightly agglomerates with and on the eyelashes. In addition, even if the entire mascara overload is not fully transferred to the eyelashes, the unused mascara, left on the brush, is reintroduced into the mascara stock, within the container, which increases the risk of defilement and contamination of the latter. This residue of mascara remained on the brush tends moreover to dry on the latter, which is likely in the long run to affect the qualities of application of the brush and to degrade the mascara stock contained in the container, by mixing from the stock with dried mascara particles.

Enfin, les brosses de l'art antérieur permettent certes d'assurer une fonction de peignage des cils lors de l'application du mascara, mais cette fonction de peignage ne suffit généralement pas à obtenir une enduction continue, uniforme et douce des cils.Finally, the brushes of the prior art certainly provide a combing function of the eyelashes during the application of mascara, but this combing function is generally not sufficient to obtain a continuous coating, uniform and soft lashes.

L'invention a en conséquence pour objet de remédier aux différents inconvénients énumérés précédemment, et de proposer un nouvel instrument pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils permettant à la fois de collecter de façon précise une juste quantité de mascara, en évitant la formation de surcharges de produit sur l'instrument, et d'appliquer ce mascara de façon sensiblement uniforme sur les cils, de manière particulièrement efficace et selon une gestuelle classique.The object of the invention is therefore to remedy the various disadvantages enumerated above, and to propose a new instrument for applying a liquid or semi-liquid product to the eyelashes or the eyebrows, which makes it possible at the same time to accurately collect a fair amount of mascara, avoiding the formation of product overloads on the instrument, and applying this mascara substantially uniformly on the eyelashes, particularly effectively and according to a conventional gesture.

Un autre objet de l'invention vise à proposer un nouvel instrument pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils de construction particulièrement simple et économique.Another object of the invention is to propose a new instrument for applying a liquid or semi-liquid product on eyelashes or eyebrows of particularly simple and economical construction.

Un autre objet de l'invention vise à proposer un nouvel instrument pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils qui permet d'obtenir un excellent résultat esthétique de maquillage des cils ou sourcils.Another object of the invention is to propose a new instrument for applying a liquid or semi-liquid product on the eyelashes or the eyebrows which makes it possible to obtain an excellent aesthetic result of makeup of eyelashes or eyebrows.

Un autre objet de l'invention vise à proposer un nouvel instrument pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils qui tout en étant de construction très simple permet de contrôler précisément la quantité de mascara collectée et de séparer, allonger et recourber les cils de façon améliorée.Another object of the invention is to propose a new instrument for applying a liquid or semi-liquid product on eyelashes or eyebrows which, while being of very simple construction, makes it possible to precisely control the amount of mascara collected and to separate, to lengthen and curling the eyelashes in an improved manner.

Un autre objet de l'invention vise à proposer un nouvel instrument pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils qui permet un lissage sensiblement uniforme des cils.Another object of the invention is to propose a new instrument for applying a liquid or semi-liquid product on the eyelashes or the eyebrows which allows a substantially uniform smoothing of the eyelashes.

Un autre objet de l'invention vise à proposer un nouvel instrument pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils dont l'allure visuelle générale est comparable à celle des instruments classiques de l'art antérieur, de sorte que l'utilisateur en connaît intuitivement le principe d'utilisation.Another object of the invention is to propose a new instrument for applying a liquid or semi-liquid product to eyelashes or eyebrows whose general visual appearance is comparable to that of conventional instruments of the prior art, so that the user intuitively knows the principle of use.

Les objets assignés à l'invention sont atteints à l'aide d'un instrument pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils comprenant une âme s'étendant selon une direction axiale ainsi qu'au moins des première, seconde, troisième et quatrième excroissances faisant saillie à partir de l'âme, caractérisé en ce que les première et seconde excroissances, qui forment un premier groupe d'excroissances, sont mutuellement espacées d'un premier écartement pour définir un premier espace interstitiel en forme de lame s'étendant au moins localement selon un plan sensiblement perpendiculaire à la direction axiale, ledit premier espace interstitiel étant conformé et dimensionné pour retenir du produit en son sein en vue de l'appliquer sur les cils ou sourcils, les troisième et quatrième excroissances, qui forment un second groupe d'excroissances, étant mutuellement espacées d'un second écartement pour définir un second espace interstitiel en forme de lame s'étendant au moins localement selon un plan sensiblement perpendiculaire à la direction axiale, ledit second espace interstitiel étant conformé et dimensionné pour retenir du produit en son sein en vue de l'appliquer sur les cils ou sourcils, les premier et deuxième groupes étant mutuellement espacés d'un troisième écartement sensiblement supérieur à la fois au premier et au second écartement.The objects assigned to the invention are achieved with the aid of an instrument for applying a liquid or semi-liquid product to the eyelashes or the eyebrows comprising a core extending in an axial direction and at least of the first, second, third and fourth protuberances protruding from the core, characterized in that the first and second protuberances, which form a first group of excrescences, are mutually spaced apart by a first gap to define a first interstitial space in shape blade member extending at least locally in a plane substantially perpendicular to the axial direction, said first interstitial space being shaped and dimensioned to retain product therein for application to the eyelashes or eyebrows, the third and fourth excrescences , which form a second group of excrescences, being mutually spaced apart by a second gap to define a second blade-shaped interstitial space extending at least locally in a plane substantially perpendicular to the axial direction, said second interstitial space being shaped and sized to retain product therein in order to apply it to the eyelashes or eyebrows, the first and second groups being mutually spaced apart by a third spacing substantially greater at both the first and the second spacing.

Les figures 1 et 2 illustrent, respectivement dans un état monté et démonté, un instrument 1 pour appliquer un produit liquide ou semi-liquide sur les cils ou les sourcils, conforme à l'invention.Figures 1 and 2 illustrate, respectively in a mounted and disassembled state, an instrument 1 for applying a liquid or semi-liquid product on the eyelashes or eyebrows, according to the invention.

Avantageusement, le produit à appliquer est un produit cosmétique, de sorte que l'instrument 1 constitue dans ce cas un instrument cosmétique.Advantageously, the product to be applied is a cosmetic product, so that the instrument 1 constitutes in this case a cosmetic instrument.

De façon préférentielle, le produit à appliquer est du mascara pour les cils, l'instrument 1 constituant alors un applicateur à mascara pour les cils.Preferably, the product to be applied is mascara for the eyelashes, the instrument 1 then constituting a mascara applicator for the eyelashes.

Dans un souci de simplicité de description, il sera fait référence dans ce qui suit exclusivement à un tel applicateur à mascara. L'invention n'est cependant pas limitée à l'application d'un produit présentant une nature exclusivement cosmétique, ni à l'application d'un produit présentant nécessairement des propriétés identiques à celles d'un mascara. L'instrument 1 pourra ainsi être utilisé pour appliquer tout produit liquide ou semi-liquide quelle que soit sa consistance, ledit produit pouvant par exemple être très fluide ou présenter à l'inverse un caractère très visqueux et pâteux.For the sake of simplicity of description, reference will be made hereinafter exclusively to such a mascara applicator. The invention is however not limited to the application of a product having an exclusively cosmetic nature, or the application of a product necessarily having properties identical to those of a mascara. The instrument 1 can thus be used to apply any liquid or semi-liquid product regardless of its consistency, said product may for example be very fluid or have conversely a very viscous and pasty.

De manière connue en soi, l'instrument 1 comporte un organe de préhension 2 conçu pour être saisi et manipulé manuellement par un utilisateur, par exemple entre deux ou trois doigts. L'instrument 1 présente donc, de manière classique, un caractère portable et est destiné à une utilisation manuelle.In a manner known per se, the instrument 1 comprises a gripping member 2 designed to be grasped and manipulated manually by a user, for example between two or three fingers. The instrument 1 therefore presents, in a conventional manner, a portable character and is intended for manual use.

De façon préférentielle, l'organe de préhension 2 peut également faire office de bouchon pour un récipient (non représenté) contenant un stock de produit à appliquer, lequel est de préférence du mascara pour les cils.Preferably, the gripping member 2 may also serve as a cap for a container (not shown) containing a product stock to be applied, which is preferably mascara for the eyelashes.

A cette fin, l'organe de préhension 2 peut être pourvu d'un taraudage 2A, destiné à coopérer avec un filetage (non représenté) conjugué s'étendant autour de l'ouverture du récipient à obturer. Un tel agencement est classique, et ne sera donc pas décrit en détails plus avant.To this end, the gripping member 2 may be provided with a tapping 2A, intended to cooperate with a thread (not shown) conjugate extending around the opening of the container to be closed. Such an arrangement is conventional, and will not be described in detail further.

Avantageusement, l'instrument 1 comprend une tige 3 s'étendant de façon sensiblement rectiligne à partir de l'organe de préhension 2 entre une extrémité proximale 3A et une extrémité distale 3B.Advantageously, the instrument 1 comprises a rod 3 extending substantially rectilinearly from the gripping member 2 between a proximal end 3A and a distal end 3B.

Conformément à l'invention, l'instrument 1 comprend une âme 4, laquelle est de préférence positionnée vers l'extrémité distale 3B de la tige 3.According to the invention, the instrument 1 comprises a core 4, which is preferably positioned towards the distal end 3B of the rod 3.

L'âme 4 s'étend selon une direction axiale X-X', de préférence de façon sensiblement rectiligne à partir de l'extrémité distale 3B dans le prolongement de la tige 3. Dans ce cas illustré aux figures, l'âme 4 est distincte de la tige 3.The core 4 extends in an axial direction X-X ', preferably substantially rectilinearly from the distal end 3B in the extension of the rod 3. In this case illustrated in the figures, the core 4 is distinct from the stem 3.

Il est cependant tout à fait envisageable que l'âme 4 soit directement formée par la tige 3 elle-même.It is however quite possible that the core 4 is directly formed by the rod 3 itself.

Il est également envisageable que l'âme 4 ne s'étende pas de façon strictement rectiligne, tel que cela est illustré aux figures, mais présente par exemple plutôt une forme légèrement courbe, conjuguée au profil d'implantation des cils. Dans ce cas la direction axiale X-X' n'est bien évidemment pas définie par une droite, mais par une ligne courbe qui suit le contour d'extension de l'âme 4.It is also conceivable that the core 4 does not extend in a strictly rectilinear manner, as is illustrated in the figures, but has for example rather a slightly curved shape, conjugated to the implantation profile of the eyelashes. In this case the axial direction X-X 'is obviously not defined by a straight line, but by a curved line which follows the extension contour of the core 4.

De façon préférentielle, l'âme 4 présente une forme allongée, élancée. En d'autres termes, l'âme 4 présente avantageusement une forme longiligne, c'est-à-dire qu'elle s'étend majoritairement selon une seule direction de l'espace. En cela, l'âme 4 peut être qualifiée dans ce cas de monodimensionnelle.Preferably, the core 4 has an elongated, slender shape. In other words, the core 4 advantageously has an elongated shape, that is to say it extends mainly in a single direction of space. In this, the soul 4 can be qualified in this case of one-dimensional.

De façon préférentielle, tel que cela est illustré aux figures 1 à 3 et 10, l'âme 4 se présente sous la forme d'une pièce unitaire monobloc.Preferably, as illustrated in FIGS. 1 to 3 and 10, the core 4 is in the form of a unitary unitary piece.

Il est toutefois envisageable, tel que cela est illustré aux figures 4 à 9, que l'âme 4 soit formée d'au moins deux pièces unitaires distinctes et indépendantes 4A, 4B. 4C, 4D disposées bout à bout dans la continuité et le prolongement les unes des autres.However, it is conceivable, as is illustrated in Figures 4 to 9, that the core 4 is formed of at least two separate and independent unit parts 4A, 4B. 4C, 4D disposed end to end in the continuity and extension of each other.

Dans l'exemple de réalisation des figures 4 à 6, l'âme 4 est ainsi formée par l'empilement de quatre pièces unitaires distinctes 4A, 4B, 4C, 4D.In the embodiment of Figures 4 to 6, the core 4 is thus formed by the stack of four separate unit parts 4A, 4B, 4C, 4D.

Dans un mode de réalisation particulièrement avantageux et qui est illustré aux figures, l'âme 4 se présente sous la forme d'une pièce mono-corps (cf. figures 1 à 3) ou multi-corps (cf. figures 5 à 9) longiligne percée sur toute sa longueur d'un trou débouchant 5. De façon préférentielle, l'âme 4 présente une forme sensiblement cylindrique, de préférence de base circulaire, le trou 5 étant ménagé en son centre.In a particularly advantageous embodiment, which is illustrated in the figures, the core 4 is in the form of a single-body piece (see FIGS. 1 to 3) or a multi-body piece (FIGS. longiligne pierced along its entire length of a through hole 5. Preferably, the core 4 has a substantially cylindrical shape, preferably circular base, the hole 5 being formed at its center.

Dans cette variante, l'âme 4 forme un fourreau destiné à être enfilé sur une épingle 6 s'étendant entre une première extrémité 6A et une deuxième extrémité 6B. Le fourreau formant l'âme 4 est destiné à être enfilé sur l'épingle 6 par la première extrémité 6A, la seconde extrémité 6B étant pourvue d'un moyen de butée 7 contre lequel le fourreau est destiné à venir en appui. Dans l'exemple de réalisation illustré aux figures 1 à 3, le moyen de butée 7 peut par exemple être simplement constitué d'un disque venant de matière avec la tige 6 et dont le diamètre est supérieur à celui du trou 5.In this variant, the core 4 forms a sleeve intended to be threaded onto a pin 6 extending between a first end 6A and a second end 6B. The sleeve forming the core 4 is intended to be threaded onto the pin 6 by the first end 6A, the second end 6B being provided with a stop means 7 against which the sleeve is intended to bear. In the exemplary embodiment illustrated in FIGS. 1 to 3, the abutment means 7 may for example simply consist of a disk made of material with the rod 6 and whose diameter is greater than that of the hole 5.

L'autre extrémité 6A de l'épingle 6 est avantageusement pourvue d'un moyen de fixation à l'extrémité distale 3B de la tige 3. La première extrémité 6A peut comprendre par exemple, tel que cela est illustré aux figures, une gorge 8, la première extrémité 6A étant destinée à être enfilée dans un orifice ménagé axialement dans la tige 3. L'assemblage final est alors réalisé par sertissage de l'épingle 6, sertissage obtenu par déformation centripète de la matière formant la tige 3 dans la gorge 8.The other end 6A of the pin 6 is advantageously provided with a fixing means at the distal end 3B of the rod 3. The first end 6A may comprise, for example, as shown in the figures, a groove 8 , the first end 6A being intended to be threaded into an orifice formed axially in the rod 3. The final assembly is then achieved by crimping the pin 6, crimping obtained by centripetal deformation of the material forming the rod 3 in the throat 8.

Conformément à l'invention, l'instrument comprend au moins des première, seconde, troisième et quatrième excroissances 14, 15, 16, 17 faisant saillie à partir de l'âme 4. En d'autres termes, chaque excroissance 14, 15, 16, 17 est proéminente relativement à l'âme 4 et forme une protubérance à partir de ladite âme 4. De préférence, chaque excroissance 14, 15, 16, 17 s'étend radialement relativement à l'axe de symétrie X-X' de l'âme 4.According to the invention, the instrument comprises at least first, second, third and fourth protuberances 14, 15, 16, 17 protruding from the core 4. In other words, each protrusion 14, 15, 16, 17 is prominent relative to the core 4 and forms a protuberance from said core 4. Preferably, each protrusion 14, 15, 16, 17 extends radially relatively to the axis of symmetry XX 'of the core 4.

Les excroissances 14, 15, 16, 17 forment ainsi avantageusement un moyen d'application 9 conçu pour collecter du produit et l'appliquer sur les cils (ou les sourcils). Le moyen d'application 9 formé par les excroissances 14, 15, 16, 17 est donc spécifiquement conçu pour prélever du produit à appliquer, par exemple en étant immergé dans une réserve de ce dernier, et pour retenir et contenir cette quantité de produit prélevé jusqu'à son relâchement sur les cils, effectué de préférence par mise en contact et frottement des moyens d'application 9 avec et contre les cils.The protuberances 14, 15, 16, 17 thus advantageously form an application means 9 designed to collect product and apply it on the eyelashes (or the eyebrows). The application means 9 formed by the protuberances 14, 15, 16, 17 is therefore specifically designed to take the product to be applied, for example by being immersed in a reserve of the latter, and to retain and contain this amount of product withdrawn until loosening on the eyelashes, preferably by contacting and rubbing the application means 9 with and against the eyelashes.

Le moyen d'application 9, formé par les excroissances 14, 15, 16, 17, s'étend par conséquent en saillie à partir de l'âme 4, entre une base 9A et un sommet 9B. La base 9A correspond à la base individuelle de chaque excroissance, tandis que le sommet 9B correspond au sommet individuel de chaque excroissance.The application means 9, formed by the protuberances 14, 15, 16, 17, therefore protrudes from the core 4 between a base 9A and a vertex 9B. The base 9A corresponds to the individual base of each outgrowth, while the vertex 9B corresponds to the individual vertex of each outgrowth.

Conformément à l'invention, les première et seconde excroissances 14, 15, qui forment un premier groupe d'excroissances 140, sont mutuellement espacées d'un premier écartement E1 pour définir un premier espace interstitiel S1 en forme de lame. En d'autres termes, le premier espace interstitiel S1 est un espace vide présentant sensiblement une forme de bande plate et mince, bidimensionnelle, que l'on pourrait également qualifier de forme « en plaque ».According to the invention, the first and second protuberances 14, 15, which form a first group of excrescences 140, are mutually spaced from a first gap E1 to define a first interstitial space S1 blade-shaped. In other words, the first interstitial space S1 is a void space substantially in the form of a flat, thin, two-dimensional strip, which could also be described as a " plate " shape.

Dans les exemples illustrés aux figures, les première et seconde excroissances 14, 15 sont alignées sensiblement parallèlement à la direction axiale X-X', de sorte que l'écartement E1, qui correspond à l'épaisseur ou à la tranche de l'espace S1 en forme de lame, est mesuré selon la direction axiale X-X'.In the examples illustrated in the figures, the first and second protuberances 14, 15 are aligned substantially parallel to the axial direction X-X ', so that the spacing E1 , which corresponds to the thickness or slice of the space S1 in the form of a blade, is measured in the axial direction X-X '.

Conformément à l'invention, le premier espace interstitiel S1 en forme de lame s'étend au moins localement selon un plan sensiblement perpendiculaire à la direction axiale X-X'. En d'autres termes, en projection selon une vue de dessus (voir par exemple les figures 13 à 16), le premier espace interstitiel S1 s'étend selon une direction générale sensiblement orthogonale à la direction axiale X-X'. Ainsi, l'espace interstitiel S1 et l'âme 4 s'étendent localement, c'est-à-dire par exemple au niveau du raccordement des excroissances 14, 15 à l'âme 4, selon deux plans sensiblement sécants, orthogonaux.According to the invention, the first blade-shaped interstitial space S1 extends at least locally in a plane substantially perpendicular to the axial direction X-X '. In other words, in projection in a view from above (see for example Figures 13 to 16), the first interstitial space S1 extends in a general direction substantially orthogonal to the axial direction X-X '. Thus, the interstitial space S1 and the core 4 extend locally, that is to say for example at the connection of the protrusions 14, 15 to the core 4, in two substantially intersecting, orthogonal planes.

Conformément à l'invention, le premier espace interstitiel S1 est conformé et dimensionné pour retenir du produit en son sein en vue de l'appliquer sur les cils (ou les sourcils). En particulier, le premier espace interstitiel S1 définit un volume d'application 11 conformé et dimensionné pour d'une part contenir du produit à appliquer et d'autre part, de façon préférentielle, permettre le passage en son sein d'au moins un cil (ou sourcil) pour enduire ce dernier de produit.According to the invention, the first interstitial space S1 is shaped and sized to retain product within it for application to the eyelashes (or eyebrows). In particular, the first interstitial space S1 defines an application volume 11 shaped and dimensioned so as, on the one hand, to contain the product to be applied and, on the other hand, preferably, to allow the passage within it of at least one eyelash (or eyebrow) to coat the product.

En d'autres termes, l'espace interstitiel S1 ménage une cavité, dont au moins une partie forme un réceptacle, correspondant au volume d'application 11, destiné à collecter, contenir et retenir du produit à appliquer.In other words, the interstitial space S1 provides a cavity, at least a portion of which forms a receptacle, corresponding to the application volume 11, intended to collect, contain and retain the product to be applied.

En particulier, l'espace interstitiel S1 forme préférentiellement une vacuole qui, lorsqu'elle est immergée dans une réserve de produit liquide (ou semi-liquide) à appliquer, se remplit dudit produit et le retient en son sein par un mécanisme de tension superficielle et/ou de capillarité.In particular, the interstitial space S1 preferably forms a vacuole which, when immersed in a reserve of liquid (or semi-liquid) product to be applied, fills with said product and retains within it by a surface tension mechanism. and / or capillarity.

Le premier espace interstitiel S1 et son volume d'application associé 11 sont ainsi spécifiquement dimensionnés et conformés en regard des caractéristiques physico-chimiques du produit à appliquer, et en particulier de sa viscosité et de sa consistance, pour que chaque volume d'application 11 retienne efficacement une quantité prédéterminée de produit en son sein, quelle que soit l'orientation du volume 11 dans l'espace.The first interstitial space S1 and its associated application volume 11 are thus specifically sized and shaped with respect to the physicochemical characteristics of the product to be applied, and in particular its viscosity and consistency, so that each application volume 11 effectively retains a predetermined amount of product therein, regardless of the orientation of the volume 11 in space.

Afin de permettre le passage en son sein d'au moins un cil pour enduire ce dernier de produit, l'espace interstitiel S1 présente, sur au moins une fraction de son étendue totale, une dimension E1 préférentiellement supérieure à cette de la taille (diamètre) d'un cil (ou d'un sourcil).In order to allow at least one eyelash to pass therethrough in order to coat the latter with the product, the interstitial space S1 has, over at least a fraction of its total extent, a dimension E1 that is preferentially greater than that of the size (diameter ) an eyelash (or an eyebrow).

De préférence, tel que cela est illustré aux figures, le volume d'application 11 débouche vers l'extérieur, afin de permettre la pénétration directe des cils en son sein lors d'une action de brossage des cils avec l'instrument 1.Preferably, as shown in the figures, the application volume 11 opens outwards, to allow the eyelashes to penetrate directly into it during an action of brushing the eyelashes with the instrument 1.

Conformément à l'invention, les troisième et quatrième excroissances 16, 17, qui forment un second groupe d'excroissances 150, sont mutuellement espacées d'un second écartement E2 pour définir un second espace interstitiel S2 en forme de lame s'étendant au moins localement selon un plan sensiblement perpendiculaire à la direction axiale X-X', ledit second espace interstitiel étant conformé et dimensionné pour retenir du produit en son sein en vue de l'appliquer sur les cils ou les sourcils.According to the invention, the third and fourth protuberances 16, 17, which form a second group of protuberances 150, are mutually spaced apart by a second gap E2 to define a second blade-shaped interstitial space S2 extending at least locally in a plane substantially perpendicular to the axial direction X-X ', said second interstitial space being shaped and sized to retain product therein for application to the eyelashes or eyebrows.

Les détails de description évoqués dans ce qui précède concernant le premier groupe 140 sont donc également valables pour le second groupe 150, et ne seront donc pas repris plus en détails ci-après. En d'autres termes, les premier et second groupes 140, 150 présentent des conceptions générales sensiblement similaires, ce qui n'exclut bien entendu pas que leurs structures diffèrent.The details of description mentioned in the foregoing concerning the first group 140 are therefore also valid for the second group 150, and will therefore not be repeated in more detail hereinafter. In other words, the first and second groups 140, 150 have substantially similar general conceptions, which of course does not exclude that their structures differ.

Avantageusement, chacun des premier et second espaces interstitiels S1, S2 présente une forme sensiblement parallélépipédique, tel que cela est illustré aux figures 1 à 14 et 17. Il est toutefois envisageable que lesdits espaces interstitiels S1, S2 présentent une forme autre, et par exemple une forme présentant une restriction de section centrale (cf. figure 15), une forme courbe (cf. figure 16) voire ondulée (non représenté).Advantageously, each of the first and second interstitial spaces S1 , S2 has a substantially parallelepipedal shape, as is 1 to 14 and 17. However, it is conceivable that said interstitial spaces S1, S2 have a different shape, and for example a shape having a central section restriction (see Figure 15), a curved shape (see FIG. 16) or corrugated (not shown).

Avantageusement, les excroissances 14, 15. 16, 17, et donc le moyen d'application 9, viennent de matière avec l'âme 4. En d'autres termes, dans ce mode de réalisation avantageux qui est mis en oeuvre par toutes les variantes illustrées aux figures, les excroissances 14, 15, 16, 17 et l'âme 4 forment un seul et même sous-ensemble unitaire.Advantageously, the protuberances 14, 15, 16, 17, and therefore the application means 9, come from material with the core 4. In other words, in this advantageous embodiment which is implemented by all variants illustrated in the figures, the protuberances 14, 15, 16, 17 and the core 4 form a single unitary subassembly.

De manière préférentielle, l'âme 4 et les excroissances 14, 15, 16, 17 sont obtenus en une seule opération d'injection/moulage d'une matière plastique, de préférence un élastomère ou un polymère du genre PTFE (polytétrafluoroéthylène). L'invention se prête donc particulièrement bien à une fabrication par injection de matière plastique, qui s'avère rapide et économique. Bien évidemment, l'invention n'est pas limitée à un instrument 1 mettant en oeuvre un moyen d'application 9 venant de matière avec l'âme 4. Le moyen d'application 9 peut être distinct de l'âme 4 et être fixé sur cette dernière par tout moyen approprié, et par exemple par collage, thermosoudure ou assemblage mécanique.Preferably, the core 4 and the protuberances 14, 15, 16, 17 are obtained in a single injection / molding operation of a plastic material, preferably an elastomer or a polymer of the PTFE (polytetrafluoroethylene) type. The invention is therefore particularly suitable for plastic injection molding, which is fast and economical. Obviously, the invention is not limited to an instrument 1 implementing an application means 9 coming from material with the core 4. The application means 9 may be separate from the core 4 and be fixed on the latter by any appropriate means, for example by gluing, heat sealing or mechanical assembly.

Dans un mode de réalisation alternatif non représenté, il est également envisageable que l'âme 4 ne soit pas fabriquée avec un orifice central 5, mais avec directement une portion d'épingle faisant saillie à l'une de ses extrémités et destinée à interagir avec un trou correspondant ménagé dans la partie proximale 3B de la tige 3. Dans cette variante avantageuse, le moyen d'application 9 (comprenant les excroissances 14, 15, 16, 17), l'âme 4 et la portion d'épingle 6 sont réalisés simultanément en une seule opération d'injection/moulage.In an alternative embodiment not shown, it is also conceivable that the core 4 is not manufactured with a central orifice 5, but with a straight pin portion projecting from one of its ends and intended to interact with a corresponding hole in the proximal portion 3B of the rod 3. In this advantageous variant, the application means 9 (including the protuberances 14, 15, 16, 17), the core 4 and the pin portion 6 are performed simultaneously in a single injection / molding operation.

De façon préférentielle, tel que cela est en particulier visible aux figures 1 à 6, l'instrument 1 comprend une pluralité d'excroissances 14, 15, 16, 17 coopérant par paires, chaque paire formant un groupe 140, 150, et chaque groupe 140, 150 définissant un volume d'application 11 correspondant.Preferably, as is particularly visible in Figures 1 to 6, the instrument 1 comprises a plurality of excrescences 14, 15, 16, 17 cooperating in pairs, each pair forming a group 140, 150, and each group 140, 150 defining a corresponding application volume 11.

Avantageusement, au moins les première, seconde, troisième et quatrième excroissances sont sensiblement alignées, de préférence parallèlement à la direction axiale X-X'. Lesdites excroissances forment ainsi une rangée. Tel que cela est illustré aux figures, l'instrument 1 comprend avantageusement plusieurs rangées similaires, s'étendant parallèlement à la direction axiale X-X' et disposées à intervalles angulaires réguliers le long de la périphérie de l'âme 4, laquelle présente de préférence une section sensiblement circulaire.Advantageously, at least the first, second, third and fourth protuberances are substantially aligned, preferably parallel to the axial direction X-X '. Said growths thus form a row. As illustrated in the figures, the instrument 1 advantageously comprises several similar rows, extending parallel to the axial direction XX 'and arranged at regular angular intervals along the periphery of the core 4, which preferably has a substantially circular section.

Ainsi, l'invention permet de créer au moins deux et de préférence une multitude de volumes d'application 11 spécialement adaptés pour la rétention de produit à appliquer. De surcroît, l'orientation perpendiculaire des espaces interstitiels S1, S2 relativement à l'axe X-X', orientation qui correspond lors de l'utilisation à la direction d'extension des cils, permet d'optimiser le gainage des cils par le produit lors de l'application.Thus, the invention makes it possible to create at least two and preferably a multitude of application volumes 11 specially adapted for the retention of the product to be applied. In addition, the perpendicular orientation of the interstitial spaces S1 , S2 relative to the axis X-X ', which corresponds in use to the direction of extension of the eyelashes, makes it possible to optimize the cladding of the eyelashes by the produced during the application.

Conformément à une caractéristique importante de l'invention, les premier et deuxième groupes 140, 150 sont mutuellement espacés d'un troisième écartement E3 sensiblement supérieur à la fois au premier écartement E1 et au second écartement E2. En d'autres termes, la distance séparant chaque groupe 140, 150, en particulier selon la direction axiale X-X', est supérieure à la distance séparant deux excroissances au sein d'un même groupe. Cette caractéristique permet de minimiser un éventuel effet de rétention de produit entre les groupes, et de favoriser au contraire l'évacuation du produit entre les groupes 140, 150. De cette façon, le produit à appliquer est préférentiellement concentré au sein de chaque groupe 140, 150, dans l'espace interstitiel S1, S2 correspondant, et ne s'accumule pas inutilement dans des zones qui ne sont pas directement destinées à interagir avec les cils. Cela permet un chargement contrôlé et optimal de l'instrument en produit à appliquer, qui facilite et améliore le maquillage tout en limitant les risques de dégradation de l'instrument 1 et/ou de souillure et contamination de la réserve de produit.According to an important feature of the invention, the first and second groups 140, 150 are mutually spaced apart by a third gap E3 substantially greater than both the first gap E1 and the second gap E2 . In other words, the distance separating each group 140, 150, in particular in the axial direction X-X ', is greater than the distance separating two excrescences within the same group. This characteristic makes it possible to minimize a possible effect of product retention between the groups, and to favor on the contrary the evacuation of the product between the groups 140, 150. In this way, the product to be applied is preferentially concentrated within each group. , 150, in the interstitial space S1 , S2 corresponding, and does not accumulate unnecessarily in areas that are not directly intended to interact with the eyelashes. This allows a controlled and optimal loading of the instrument product to be applied, which facilitates and improves makeup while limiting the risk of degradation of the instrument 1 and / or contamination and contamination of the product stock.

De façon avantageuse, le troisième écartement E3 est spécifiquement dimensionné pour empêcher toute accumulation du produit à appliquer dans l'espace existant entre les groupes 140, 150. Cet effet technique peut être plus ou moins intense selon la grandeur de l'écartement E3. Advantageously, the third gap E3 is specifically sized to prevent any accumulation of the product to be applied in the space between the groups 140, 150. This technical effect may be more or less intense depending on the size of the spacing E3.

La mise en oeuvre d'un troisième écartement E3 supérieur aux premier et second écartement E1 et E2 permet également un peignage amélioré des cils.The implementation of a third spacing E3 greater than the first and second spacing E1 and E2 also allows improved combing of the eyelashes.

Avantageusement, l'un ou l'autre (ou les deux) des écartements E1 et E2 est compris entre environ 0,1 et 2 millimètres, et plus préférentiellement encore entre 0,3 et 0,7 millimètre, les valeurs préférées étant comprises entre 0,4 et 0,5 millimètre, les bornes de cette dernière plage conférant d'excellents résultats.Advantageously, one or the other (or both) spacings E1 and E2 is between about 0.1 and 2 millimeters, and even more preferably between 0.3 and 0.7 millimeters, the preferred values being between 0.4 and 0.5 millimeters, the boundaries of this last range conferring excellent results.

On notera que dans le cas des variantes illustrées aux figures 1 à 10, les premier et second écartements E1, E2 doivent être mesurés dans une zone supérieure de l'espace interstitiel correspondant S1, S2 compte-tenu du fait que lesdits espaces interstitiels S1, S2 définissent vers la base 9B du moyen d'application 9, un espace 170 de dimension réduite (par exemple comprise entre 0,05 et 0,4 millimètre, et de préférence de l'ordre de 0,1 millimètre) qui n'est pas directement destiné à contenir et retenir du produit, mais plutôt à autoriser une meilleure flexion de chaque excroissance 14, 15. L'espace 170 est donc préférentiellement dimensionné en regard des propriétés physico-chimiques (viscosité, tension superficielle notamment) du produit à appliquer pour empêcher, ou du moins limiter, la pénétration du produit en son sein. L'espace 170 pourra également être choisi pour être plus petit que le diamètre d'un cil, de façon à interdire la pénétration d'un cil en son sein.It will be noted that, in the case of the variants illustrated in FIGS. 1 to 10, the first and second spacings E1 , E2 must be measured in an upper zone of the corresponding interstitial space S1 , S2 , given that said interstitial spaces S1 , S2 define towards the base 9B of the application means 9, a space 170 of reduced size (for example between 0.05 and 0.4 millimeters, and preferably of the order of 0.1 millimeters) which is not not directly intended to contain and retain the product, but rather to allow a better flexion of each outgrowth 14, 15. The space 170 is therefore preferably dimensioned with respect to the physicochemical properties (Viscosity, surface tension in particular) of the product to be applied to prevent, or at least limit, the penetration of the product within it. The space 170 may also be chosen to be smaller than the diameter of an eyelash, so as to prevent the penetration of an eyelash into it.

Dans le cas de la variante illustrée à la figure 17, la section des premier et second espaces interstitiels S1, S2 est sensiblement constante selon toute la longueur des excroissances correspondantes 14, 15, 16, 17, de sorte que la mesure des écartements E1, E2 pourra être effectué à n'importe quel distance radiale de l'âme 4.In the case of the variant illustrated in FIG. 17, the section of the first and second interstitial spaces S1 , S2 is substantially constant along the entire length of the corresponding excrescences 14, 15, 16, 17, so that the measurement of the spacings E1 , E2 can be performed at any radial distance from the core 4.

De manière générale, les premier et second écartements E1, E2 correspondent à la dimension caractéristique des premier et second espaces interstitiels en relation avec la fonction de rétention et d'application du produit sur les cils décrite dans ce qui précède.In a general manner, the first and second spacings E1 , E2 correspond to the characteristic dimension of the first and second interstitial spaces in relation to the function of retention and application of the product on the eyelashes described above.

De façon préférentielle, les premier et second écartements E1, E2 sont sensiblement égaux. Il est cependant tout à fait envisageable, sans que l'on sorte du cadre de l'invention, que les premier et second écartements E1, E2 différent, dans la mesure où les premier et second espaces interstitiels S1, S2 qu'ils définissent respectivement remplissent la fonction de rétention de produit visée précédemment.Preferably, the first and second spacings E1 , E2 are substantially equal. However, it is quite possible, without departing from the scope of the invention, for the first and second spacings E1 , E2 to be different, insofar as the first and second interstitial spaces S1, S2 which they respectively define fulfill the product retention function referred to above.

Avantageusement, le troisième écartement E3 est quant à lui sensiblement compris entre 0,2 et 4 millimètres.Advantageously, the third gap E3 is meanwhile substantially between 0.2 and 4 millimeters.

De façon préférentielle, le troisième écartement est égal à sensiblement le double du premier ou du second écartement E1, E2, les premier et second écartements E1, E2 étant égaux. Le choix d'un tel ratio s'avère présenter un excellent compromis en terme de capacité de rétention de produit au niveau des volumes d'application 11 et d'évacuation de produit entre les groupes 140, 150.Preferably, the third spacing is equal to substantially twice the first or second spacing E1 , E2 , the first and second spacings E1 , E2 being equal. The choice of such a ratio proves to be an excellent compromise in terms of product retention capacity at the level of application volumes 11 and product evacuation between the groups 140, 150.

Dans une variante particulièrement préférée, le premier et le second écartements E1, E2 sont chacun sensiblement égaux à 0,4 millimètre, tandis que le troisième écartement E3 est sensiblement égal à 0,8 millimètre.In a particularly preferred variant, the first and second spacings E1 , E2 are each substantially equal to 0.4 millimeters, while the third spacing E3 is substantially equal to 0.8 millimeters.

Avantageusement, chaque excroissance 14, 15 est formée par une lamelle souple, réalisée de préférence en un matériau élastomère ou en un matériau polymère, du genre PTFE par exemple.Advantageously, each protrusion 14, 15 is formed by a flexible blade, preferably made of an elastomeric material or a polymer material, of the PTFE type, for example.

Avantageusement, chaque lamelle présente une section transversale de forme sensiblement polygonale, de préférence sensiblement rectangulaire tel que cela est illustré aux figures 1 à 12 et 17, ou en losange (figure 15), ou en hexagone (figure 14) par exemple. D'autres formes de section sont bien évidemment envisageables, et par exemple, de façon non limitative, des formes en portions de disques coupées de façon rectiligne (figure 13), ou en croissant (figure 16).Advantageously, each strip has a cross section of substantially polygonal shape, preferably substantially rectangular as shown in Figures 1 to 12 and 17, or rhombus (Figure 15), or hexagon (Figure 14) for example. Other section shapes are of course conceivable, and for example, but not limited to, shapes in portions of disks cut in a rectilinear manner (FIG. 13), or in a crescent shape (FIG. 16).

Chaque lamelle assure de préférence une double fonction, puisque d'une part elle contribue à former un espace interstitiel en relation avec au moins une autre lamelle, et d'autre part elle forme une dent permettant un peignage des cils.Each lamella preferably has a dual function, since, on the one hand, it contributes to forming an interstitial space in relation to at least one other lamella, and on the other hand it forms a tooth making it possible to comb the eyelashes.

Dans l'exemple de réalisation illustré à la figure 12, chaque paire d'excroissances 14, 15, 16, 17 d'un groupe 140, 150 donné est issue d'un pied unique commun 160, 161 qui se subdivise de la base 9A vers le sommet 9B en deux bras formant respectivement les deux excroissances 14, 15, 16, 17 d'un groupe donné 140, 150.In the exemplary embodiment illustrated in FIG. 12, each pair of excrescences 14, 15, 16, 17 of a given group 140, 150 originates from a single common foot 160, 161 which is subdivided from the base 9A. towards the vertex 9B in two arms respectively forming the two protuberances 14, 15, 16, 17 of a given group 140, 150.

Dans les modes de réalisation illustrés en particulier aux figures 1 à 11 et 17, et qui sont des modes de réalisation préférés, les première et deuxième excroissances 14, 15 du premier groupe 140 d'une part et/ou les troisième et quatrième excroissances 16, 17 du second groupe 150 d'autre part s'étendent indépendamment l'une de l'autre à partir de l'âme 4, c'est-à-dire que les excroissances au sein d'un groupe donné sont sensiblement totalement distinctes sur toute leur longueur. Cette caractéristique technique permet d'améliorer les caractéristiques individuelles de flexibilité de chaque excroissance 14, 15. 16, 17 ce qui en retour améliore le confort de maquillage en favorisant un contact souple entre l'instrument 1 et les cils, et permet de réaliser un peignage efficace des cils. Cette variante préférée permet donc un excellent compromis entre d'une part le contrôle quantitatif et spatial de la quantité de produit collecté et retenu par l'instrument 1 et d'autre part la capacité de peignage de ce dernier.In the embodiments illustrated in particular in FIGS. 1 to 11 and 17, and which are preferred embodiments, the first and second excrescences 14, 15 of the first group 140 on the one hand and / or the third and fourth excrescences 16 , 17 of the second group 150 on the other hand extend independently of one another from the core 4, that is to say that the excrescences within a given group are substantially totally distinct over their entire length. This technical characteristic makes it possible to improve the individual flexibility characteristics of each protuberance 14, 15, 16, 17 which in turn improves the makeup comfort by promoting a flexible contact between the instrument 1 and the eyelashes, and makes it possible to achieve a effective combing of eyelashes. This preferred variant therefore allows an excellent compromise between, on the one hand, the quantitative and spatial control of the quantity of product collected and retained by the instrument 1 and, on the other hand, the combing capacity of the latter.

Avantageusement, les première et seconde excroissances définissent respectivement une première et une seconde parois 12, 13 disposées sensiblement en regard l'une de l'autre pour former le premier espace interstitiel S1, lesdites parois 12, 13 présentant chacune un caractère sensiblement bidimensionnel, c'est-à-dire qu'elles s'étendent selon deux directions de l'espace avec des ordres de grandeur respectifs comparables. Les parois 12, 13 forment ainsi avantageusement deux faces planes disposées au droit l'une de l'autre, et délimitant un espace libre lui-même en forme de lame. Cette mesure technique est préférée, car elle permet une rétention améliorée du produit entre les lamelles, ainsi qu'une amélioration de l'effet de gainage du cil par le produit lorsque le cil est engagé dans le volume d'application 11, et que ce dernier se déplace le long du cil sous l'effet du mouvement de brossage effectué par l'utilisateur. De façon similaire, les troisième et quatrième excroissances 16, 17 définissent également de préférence respectivement des troisième et quatrième parois 12A, 13A disposées sensiblement en regard l'une de l'autre pour former le second espace interstitiel S2, lesdites parois 12A, 13A présentant chacune un caractère sensiblement bidimensionnel, à l'instar des première et seconde parois 12, 13.Advantageously, the first and second protuberances respectively define a first and a second wall 12, 13 disposed substantially opposite one another to form the first interstitial space S1 , said walls 12, 13 each having a substantially two-dimensional character, c that is, they extend in two directions of space with comparable orders of magnitude. The walls 12, 13 thus advantageously form two planar faces disposed in line with each other, and delimiting a free space itself in the form of a blade. This technical measure is preferred because it allows an improved retention of the product between the lamellae, as well as an improvement in the effect of sheathing of the eyelash by the product when the eyelash is engaged in the application volume 11, and that last moves along the eyelash under the effect of the brushing movement performed by the user. Similarly, the third and fourth protuberances 16, 17 also preferably respectively define third and fourth walls respectively. 12A, 13A disposed substantially opposite one another to form the second interstitial space S2 , said walls 12A, 13A each having a substantially two-dimensional character, like the first and second walls 12, 13.

Tel que cela est illustré aux figures, chaque excroissance 14, 15, 16, 17, présente une face externe 14A, 15A, 16A, 17A et une face interne opposée 14B, 15B, 16B, 17B, lesdites faces internes 14B, 15B, 16B, 17B étant disposées en regard l'une de l'autre au sein d'un groupe 140, 150 donné, et contribuant à former respectivement les première et deuxième parois 12, 13, 12A, 13A.As illustrated in the figures, each protrusion 14, 15, 16, 17 has an outer face 14A, 15A, 16A, 17A and an opposite inner face 14B, 15B, 16B, 17B, said internal faces 14B, 15B, 16B , 17B being disposed facing each other within a given group 140, 150, and contributing to form respectively the first and second walls 12, 13, 12A, 13A.

Afin notamment d'obtenir une meilleure maîtrise de la quantité de produit collecté par le moyen d'application 9 et retenu dans chaque volume d'application 11, et pour éviter en particulier le transfert de produit hors des volumes d'application 11 vers des zones de l'instrument 1 qui ne sont pas directement destinées à interagir avec les cils, les première et deuxième parois 12, 13, 12A, 13A sont sensiblement pleines.In particular to obtain a better control of the amount of product collected by the application means 9 and retained in each application volume 11, and to avoid in particular the transfer of product out of the application volumes 11 to areas of the instrument 1 which are not directly intended to interact with the eyelashes, the first and second walls 12, 13, 12A, 13A are substantially full.

L'expression « sensiblement pleines » désigne ici des parois formées chacune d'une pièce de matière sensiblement continue, au contraire notamment de parois qui seraient formées par la réunion d'éléments discrets, et en particulier par la réunion de fibres ou poils disposés les uns à côté des autres. En d'autres termes, chaque paroi 12, 13, 12A, 13A présente un caractère sensiblement unitaire, ainsi qu'également un caractère continu, ou monobloc.The expression " substantially solid " here denotes walls each formed of a piece of substantially continuous material, on the contrary in particular of walls which would be formed by the union of discrete elements, and in particular by the union of fibers or bristles arranged on them. next to each other. In other words, each wall 12, 13, 12A, 13A has a substantially unitary character, as well as a continuous character, or monoblock.

Comme cela a été évoqué précédemment, les parois pleines 12, 13, 12A, 13A se font face deux à deux au sein d'un groupe donné, c'est-à-dire qu'elles sont en vis-à-vis.As has been mentioned above, the solid walls 12, 13, 12A, 13A face each other in pairs within a given group, that is to say that they are facing each other.

De préférence, les première et deuxième parois 12, 13,12A, 13A présentent chacune au moins une surface sensiblement plane, lesdites surfaces planes étant avantageusement disposées sensiblement parallèlement l'une à l'autre, tel que cela est notamment illustré aux figures 1 à 14, 16 et 17.Preferably, the first and second walls 12, 13, 12A, 13A each have at least one substantially planar surface, said flat surfaces being advantageously arranged substantially parallel to each other, as shown in particular in FIGS. 14, 16 and 17.

Bien évidemment, l'invention n'est pas limitée à la mise en oeuvre d'un volume d'application 11 délimité exclusivement par deux faces planes, ce dernier pouvant être délimité par des faces présentant un tout autre contour géométrique, et par exemple présentant plusieurs facettes planes (cf. figure 15), ou encore un contour sensiblement courbe (cf. figure 16).Obviously, the invention is not limited to the implementation of an application volume 11 delimited exclusively by two flat faces, the latter being delimited by faces having a completely different geometric outline, and for example having several flat facets (see Figure 15), or a substantially curved contour (see Figure 16).

Ainsi, les première et deuxième parois 12, 13, 12A, 13A peuvent être plutôt disposées de façon symétrique, en miroir, comme dans la variante illustrée à la figure 15 où chaque excroissance 14, 15, 16, 17 présente une section en losange, chaque espace interstitiel S1, S2 présentant ainsi une restriction de section 100 en son centre, ladite restriction de section 100 reliant deux tronçons divergents vers l'extérieur.Thus, the first and second walls 12, 13, 12A, 13A may be rather symmetrically arranged, in a mirror, as in the variant illustrated in FIG. 15, where each protrusion 14, 15, 16, 17 has a diamond section, each interstitial space S1 , S2 thus having a section restriction 100 at its center, said section restriction 100 connecting two divergent sections to the outside.

De façon préférentielle, les première et deuxième parois 12, 13, 12A, 13A présentent chacune une surface sensiblement lisse et régulière, de préférence exempte d'aspérité ou d'irrégularité géométrique, ce qui permet d'améliorer encore les effets de lissage/gainage des cils évoqués dans ce qui précède.Preferably, the first and second walls 12, 13, 12A, 13A each have a substantially smooth and even surface, preferably free of roughness or geometric irregularity, which further improves the effects of smoothing / sheathing eyelashes mentioned in the foregoing.

Le fonctionnement de l'invention est le suivant.The operation of the invention is as follows.

L'utilisateur saisit dans et à la main l'organe de préhension 2, ce dernier étant vissé sur un récipient à mascara (non représenté).The user grasps in and by hand the gripping member 2, the latter being screwed onto a mascara container (not shown).

Après dévissage de l'organe 2, l'utilisateur exerce une traction sur l'instrument 1 pour extirper le moyen d'application 9 hors du stock de mascara dans lequel il était immergé.After unscrewing the member 2, the user pulls on the instrument 1 to remove the application means 9 out of the mascara stock in which it was immersed.

Après un passage à travers un essoreur, constitué par exemple par un orifice de section réduite relativement à l'encombrement radial du moyen d'application 9, le moyen d'application 9 est à l'air libre, prêt à être mis en contact avec les cils. Dans chaque volume d'application 11 formé par les lamelles de l'instrument 1 se trouve une quantité contrôlée et prédéterminée de mascara.After passing through a wiper, constituted for example by a reduced section orifice relative to the radial size of the application means 9, the application means 9 is in the open air, ready to be brought into contact with the eyelashes. In each application volume 11 formed by the slats of the instrument 1 is a controlled and predetermined quantity of mascara.

L'espace E3 entre chaque groupe 140, 150 de lamelles est de préférence conçu pour limiter au maximum la rétention de mascara et favoriser l'évacuation de ce dernier. Le mascara est donc préférentiellement et majoritairement contenu dans chacun des volumes d'application 11.The space E3 between each group 140, 150 of slats is preferably designed to minimize the retention of mascara and promote the evacuation of the latter. The mascara is therefore preferentially and predominantly contained in each of the application volumes 11.

L'utilisateur exerce ensuite une action de peignage des cils à l'aide des excroissances 14, 15, 16, 17, l'axe de symétrie X-X' de l'instrument 1 étant sensiblement perpendiculaire à la direction d'extension des cils lors de cette action de peignage.The user then exerts an action of combing the eyelashes with the protuberances 14, 15, 16, 17, the axis of symmetry XX 'of the instrument 1 being substantially perpendicular to the direction of extension of the eyelashes during this combing action.

Au cours du peignage, les cils pénètrent, de préférence de façon individuelle, dans les volumes d'application 11, et se chargent ainsi en mascara. Grâce à la présence des lames de produit dans chaque volume d'application 11, chaque cil est individuellement gainé et lissé par le produit contenu dans le volume d'application 11.During combing, the eyelashes penetrate, preferably individually, into the application volumes 11, and thus load mascara. Thanks to the presence of the product blades in each application volume 11, each eyelash is individually sheathed and smoothed by the product contained in the application volume 11.

Chaque lamelle flexible contribue de plus à séparer nettement les cils les uns des autres.Each flexible lamella further contributes to clearly separate the eyelashes from each other.

En définitive, il a été constaté que l'instrument 1 conforme à l'invention permet d'assurer de façon améliorée les quatre fonctions suivantes ;

  • séparation des cils,
  • allongement des cils,
  • recourbement des cils,
  • et chargement des cils en mascara, pour obtenir un effet « volume ».
In the end, it has been found that the instrument 1 according to the invention makes it possible to improve the following four functions in an improved manner;
  • separation of eyelashes,
  • lengthening eyelashes,
  • curling eyelashes,
  • and loading the lashes in mascara, to obtain a " volume " effect.

A cet effet, les dimensions E1, E2 de chaque volume d'application 11, selon la direction axiale X-X', ainsi que l'écartement E3 entre chacun de ces volumes d'application 11 sont choisis en fonction de l'écartement physiologique entre les cils pour permettre de préférence et autant que possible un engagement individuel des cils dans chaque volume d'application 11.For this purpose, the dimensions E1 , E2 of each application volume 11, in the axial direction X-X ', as well as the separation E3 between each of these application volumes 11 are chosen as a function of the physiological spacing between the eyelashes to allow preferably and as much as possible an individual engagement of the eyelashes in each application volume 11.
