Description

La présente invention se rapporte à un applicateur pour l'application d'un produit cosmétique liquide, pâteux ou pulvérulent, tel qu'un vernis à ongles, un fard liquide pour les lèvres, ou bien un fond de teint liquide ou une ombre à paupières. Elle se rapporte aussi à un ensemble d'application de produit cosmétique muni d'un tel applicateur.The present invention relates to an applicator for the application of a liquid, pasty or powdery cosmetic product, such as a nail varnish, a liquid make-up for the lips, or else a liquid foundation or an eye shadow. . It also relates to a set of cosmetic product application provided with such an applicator.

Généralement, un ensemble d'application de produit cosmétique liquide comprend un réservoir pour le produit à appliquer et un applicateur pour l'application dudit produit, tel qu'un pinceau comportant une touffe de poils, fixée sur un support appelé tige de pinceau. Cet ensemble comprend, en outre, un manchon destiné à fermer le réservoir, dans ce manchon étant fixé la tige du pinceau de sorte que la touffe de poils est immergée dans ce produit.Generally, an assembly for applying a liquid cosmetic product comprises a reservoir for the product to be applied and an applicator for applying the said product, such as a brush comprising a tuft of bristles, fixed on a support called a brush rod. This set further comprises a sleeve intended to close the reservoir, in this sleeve being fixed the rod of the brush so that the tuft of bristles is immersed in this product.

Les pinceaux proposés jusqu'à maintenant laissent à désirer quant à l'homogénéité et la douceur d'application, la rapidité de maquillage, notamment en ce qui concerne l'application d'un vernis sur les ongles. Ainsi, avec un pinceau de vernis à ongles classique, il est assez fréquent, que l'utilisatrice dépose une couche de vernis non homogène, marquée de stries provenant des poils du pinceau. Cet effet est d'autant plus prononcé que l'on dépose une seconde couche de vernis sur les ongles, lorsque la première n'est pas complètement sèche.The brushes proposed up to now leave something to be desired as regards the homogeneity and the smoothness of application, the speed of makeup, in particular as regards the application of a varnish to the nails. Thus, with a conventional nail varnish brush, it is quite common for the user to deposit a layer of non-homogeneous varnish, marked with streaks originating from the bristles of the brush. This effect is all the more pronounced when a second layer of varnish is deposited on the nails, when the first is not completely dry.

En outre, un pinceau de maquillage classique, nécessite une fabrication complexe, consistant successivement à mouler d'abord la tige, à couper les poils, à les agencer en touffe, à fixer la touffe sur la tige de pinceau et, finalement à couper les poils de la touffe à la longueur souhaitée. Dans un pinceau de vernis à ongles classique, la tige est réalisée en matériau rigide ou semi-rigide thermoplastique, et les poils sont réalisés le plus souvent en Nylon® ou en polyester, d'un diamètre d'environ 4/100ème à 10/100ème de mm. L'implantation de ces poils dans la tige ne peut être effectuée que par un outillage spécialisé. Ces poils classiques sont extrudés, et du fait de leur faible diamètre, ils ne peuvent pas être fabriqués, par exemple, par moulage. On comprend que cette fabrication entraîne un prix de revient relativement élevé.In addition, a conventional makeup brush requires complex manufacture, consisting successively of first molding the rod, cutting the bristles, arranging them in a tuft, fixing the tuft on the brush rod and, finally, cutting the tuft hairs to the desired length. In a classic nail varnish brush, the rod is made of rigid or semi-rigid thermoplastic material, and the bristles are most often made of Nylon® or polyester, with a diameter of about 4/100 th to 10 / 100 th of mm. The implantation of these bristles in the rod can only be carried out by specialized tools. These conventional bristles are extruded, and because of their small diameter, they cannot be manufactured, for example, by molding. It is understood that this manufacture results in a relatively high cost price.

Une solution pour diminuer ce prix de revient, consisterait à réaliser, en une seule pièce, une tige avec des poils d'un diamètre plus important, par exemple d'un diamètre de 30/100ème de mm, mais les essais effectués par la demanderesse ont montrés qu'un vernis déposé avec un tel applicateur à gros poils, présentait des stries inesthétiques dans la couche de vernis déposée, ce que l'on cherche à éviter. La demanderesse a donc cherché une solution aux inconvénients ci-dessus.One solution to reduce this cost price would be to produce, in a single piece, a rod with bristles of a larger diameter, for example with a diameter of 30/100 th of a mm, but the tests carried out by the Applicants have shown that a varnish deposited with such a coarse applicator, presented unsightly streaks in the layer of varnish deposited, which one seeks to avoid. The Applicant has therefore sought a solution to the above drawbacks.

La présente invention a pour but, notamment, de fournir un applicateur de maquillage qui permette de réaliser un maquillage homogène, offrant une grande facilité d'application pour l'utilisateur, tout en présentant un prix de revient aussi économique que possible et ne formant pas de strie.The object of the present invention is, in particular, to provide a make-up applicator which makes it possible to make a homogeneous make-up, offering great ease of application for the user, while presenting a cost price as economical as possible and not forming streak.

De façon surprenante, la demanderesse a constaté qu'en ajustant la flexibilité de la tige d'un applicateur, il était possible d'utiliser des poils relativement raides, mais moulables, pour un applicateur de vernis à ongles. Dans ce cas, on a constaté que l'applicateur tire le produit par capillarité sur la surface de l'ongle. En quelque sorte, l'applicateur "surnage" la couche de vernis déposée, sans gratter et sans formation de strie. En outre, il élimine même tout type de stries, et une deuxième couche de vernis peut être appliquée juste après l'étalement de la première couche sans attendre son séchage, ce qui raccourcit le temps global d'application. De même, la demanderesse a constaté qu'un applicateur muni d'une tige flexible permet d'utiliser des vernis de viscosité située hors de la gamme habituellement utilisée.Surprisingly, the Applicant has found that by adjusting the flexibility of the stem of an applicator, it was possible to use relatively stiff, but moldable bristles, for a nail polish applicator. In this case, it has been found that the applicator pulls the product by capillary action on the surface of the nail. In a way, the applicator "floats" the layer of varnish deposited, without scratching and without streaking. In addition, it even eliminates all types of streaks, and a second layer of varnish can be applied just after spreading the first layer without waiting for it to dry, which shortens the overall application time. Similarly, the Applicant has found that an applicator provided with a flexible rod makes it possible to use varnishes of viscosity situated outside the range usually used.

La demanderesse a constaté, en outre, qu'en augmentant la flexibilité de la tige d'un applicateur, on pouvait obtenir une couche de vernis sur l'ongle beaucoup plus homogène qu'avec un applicateur à tige rigide, sans formation de strie.The Applicant has found, moreover, that by increasing the flexibility of the stem of an applicator, it was possible to obtain a layer of varnish on the nail that is much more homogeneous than with an applicator with a rigid stem, without streaking.

Ainsi, l'invention se rapporte à un applicateur pour l'application d'un produit de maquillage comportant une tige ayant une extrémité libre comprenant un plan d'implantation pour un organe d'application ayant une flexibilité déterminée, la tige ayant une flexibilité voisine de celle de l'organe d'application, la tige et l'organe d'application étant fabriqués en une seule pièce.Thus, the invention relates to an applicator for the application of a makeup product comprising a rod having a free end comprising an implantation plane for an application member having a determined flexibility, the rod having a similar flexibility that of the applicator member, the rod and the applicator member being produced in one piece.

Par l'expression "flexibilité voisine de l'organe d'application", on entend une flexibilité telle que, lors de l'application du produit sur une surface, par exemple d'un vernis sur un ongle, l'organe d'application et la partie flexible de la tige se courbent selon une courbure quasi-constante, notamment en arc de cercle. Cette flexibilité de la tige est choisie, notamment, de manière que la force F à appliquer pour courber la tige est comprise dans la gamme : 0,3f ≦ F ≦ 3f, f étant la force nécessaire pour courber l'organe d'application. De façon préférée, on choisit une flexibilité de la tige au plus égale à celle de l'organe d'application.By the expression "flexibility close to the applicator member" is meant a flexibility such that, when applying the product to a surface, for example a varnish on a nail, the applicator member and the flexible part of the rod are curved to an almost constant curvature, in particular in an arc. This flexibility of the rod is chosen, in particular, so that the force F to be applied to bend the rod is in the range: 0.3f ≦ F ≦ 3f, f being the force necessary to bend the applicator member. Preferably, one chooses a flexibility of the rod at most equal to that of the applicator member.

En plus des avantages mentionnés ci-dessus, l'applicateur de l'invention peut être fabriqué à un prix avantageux, et assure un maquillage confortable et de bonne qualité.In addition to the advantages mentioned above, the applicator of the invention can be manufactured at an advantageous price, and ensures comfortable and good quality makeup.

Avantageusement, la fabrication de la tige et de l'organe d'application est effectuée en une seule étape de moulage : la tige et l'organe d'application sont moulées mono-pièce, notamment en un seul matériau thermoplastique. Il est possible également, de réaliser la tige et l'organe d'application en deux matériaux différents, chimiquement compatibles ; dans ce cas, on fixe l'organe d'application sur la tige par bi-injection ou surmoulage.Advantageously, the manufacture of the rod and of the application member is carried out in a single molding step: the rod and the application member are molded in one piece, in particular from a single thermoplastic material. It is also possible to produce the rod and the applicator member in two different, chemically compatible materials; in this case, the applicator member is fixed to the rod by bi-injection or overmolding.

De préférence, le matériau thermoplastique a une dureté choisie dans la gamme de 15 Shore A à 40 Shore D et de préférence de 90 à 95 Shore A. Selon un mode préféré de réalisation, le matériau thermoplastique est du PEHD ou PEBD (polyéthylène haute ou basse densité). D'autres matériaux peuvent être utilisés, tel que les polyacétales, les polyamides, les polyéther bloc amides et les élastomères de polyester ou de polyuréthane.Preferably, the thermoplastic material has a hardness chosen from the range of 15 Shore A to 40 Shore D and preferably from 90 to 95 Shore A. According to a preferred embodiment, the thermoplastic material is HDPE or LDPE (high polyethylene or low density). Other materials can be used, such as polyacetals, polyamides, polyether block amides and polyester or polyurethane elastomers.

Selon l'invention, la tige a une longueur avantageusement choisie dans la gamme allant de 2 à 20 cm, et de préférence de 2 à 4 cm.According to the invention, the rod has a length advantageously chosen from the range from 2 to 20 cm, and preferably from 2 to 4 cm.

Selon l'invention, la tige a une section déterminée et comporte, avantageusement, dans sa partie médiane, au moins une zone de plus faible section, capable de conférer à la tige la flexibilité souhaitée.According to the invention, the rod has a determined section and advantageously comprises, in its middle part, at least one zone of smaller section, capable of giving the rod the desired flexibility.

En principe, la tige peut avoir une section de forme quelconque, mais, selon l'invention, on préfère une section circulaire ou plate. Dans le cas d'une tige de section circulaire, celle ci a un diamètre pouvant aller de 2,5 à 5 mm et de préférence de 2,5 à 3,5 mm. De façon générale la section de la tige est comprise dans la gamme allant de 4 à 20 mm, et de préférence de 6 à 12 mm.In principle, the rod may have a cross section of any shape, but, according to the invention, a circular or flat cross section is preferred. In the case of a rod of circular section, this has a diameter which can range from 2.5 to 5 mm and preferably from 2.5 to 3.5 mm. In general, the cross section of the rod is in the range from 4 to 20 mm, and preferably from 6 to 12 mm.

Avantageusement, la zone de plus faible section est une section comprise dans la gamme de 0,2 à 1,8 mm,et de préférence de 0,4 à 1,2 mm.Advantageously, the zone of smallest section is a section included in the range of 0.2 to 1.8 mm, and preferably from 0.4 to 1.2 mm.

De façon plus générale la zone de plus faible section (s) est une section choisie de sorte que le rapport S/s est compris entre 2 et 100, S étant la section la plus importante de la tige, s la section la plus petite.More generally, the zone with the smallest section (s) is a section chosen so that the ratio S / s is between 2 and 100, S being the largest section of the rod, s the smallest section.

En particulier, selon une autre possibilité pour conférer à la tige la flexibilité souhaitée, celle-ci peut comporter au moins une zone aplatie, évidée, en forme de spirale ou d'accordéon.In particular, according to another possibility to give the rod the desired flexibility, this can include at least one flattened, hollowed out area, in the form of a spiral or accordion.

L'organe d'application peut être conformé sous la forme d'au moins une boucle, d'une spatule, d'une plume ou d'une touffe de poils, éventuellement recouvertes d'un flocage. Lorsqu'on réalise une spatule ou une plume, celle-ci peut comporter au moins une fente et/ou au moins un évidement, favorisant l'emmagasinage et l'écoulement du produit.The applicator member can be shaped in the form of at least one loop, a spatula, a feather or a tuft of hairs, possibly covered with a flocking. When making a spatula or a nib, it may include at least one slot and / or at least one recess, promoting the storage and flow of the product.

Lorsqu'on réalise une touffe de poils, le plan d'implantation pour la touffe comporte, avantageusement, un nombre de poils choisi dans la gamme allant de 4 à 40 et de préférence de 8 à 35. Avantageusement, ces poils ont une longueur allant de 8 à 40 mm, et de préférence de 11 à 25 mm. Ils peuvent avoir une épaisseur choisie dans la gamme allant de 0,2 à 1,5 mm, et de préférence de 0,5 à 1 mm. Ces poils peuvent présenter une section dont la forme est choisie parmi les formes cylindrique, polygonale, cruciforme, en C, en L, en I, en H, ou en V, ou comportant au moins une rainure capillaire sur au moins une partie de leur longueur. Une partie au moins de ces poils peuvent présenter de légères ondulations sur au moins une partie de leur longueur.When a tuft of bristles is produced, the implantation plan for the tuft advantageously comprises a number of bristles chosen from the range from 4 to 40 and preferably from 8 to 35. Advantageously, these bristles have a length ranging from from 8 to 40 mm, and preferably from 11 to 25 mm. They can have a thickness chosen from the range from 0.2 to 1.5 mm, and preferably from 0.5 to 1 mm. These bristles may have a section whose shape is chosen from among cylindrical, polygonal, cruciform, C, L, I, H, or V shapes, or comprising at least one capillary groove on at least part of their length. At least part of these hairs may have slight undulations over at least part of their length.

Conformément à l'invention, la section de la touffe peut avoir une forme quelconque. Ainsi, le plan d'implantation de l'organe d'application peut avoir une forme choisi parmi les formes circulaire, polygonale, rectangulaire, en section de cercle, ovale ou cruciforme. Avantageusement, les poils sont agencés en quinconce, mais il est possible de les disposer sur une rangée rectiligne ou courbe. La distance entre les poils est choisie en fonction de la capacité de prise de produit souhaitée et/ou de la viscosité du produit.According to the invention, the section of the tuft can have any shape. Thus, the implantation plan of the applicator member can have a shape chosen from circular, polygonal, rectangular shapes, in section of a circle, oval or cruciform. Advantageously, the bristles are arranged in staggered rows, but it is possible to arrange them in a straight or curved row. The distance between the bristles is chosen according to the desired product setting capacity and / or the viscosity of the product.

L'extrémité libre des poils peut subir un traitement abrasif ou thermique, par flammage, par meulage ou par cardage. Ainsi, on peut obtenir des poils dont l'extrémité est conformée en tête d'épingle ou effilée, ce qui augmente la capacité de prise de produit de l'applicateur, et donc son autonomie d'application.The free end of the bristles can be subjected to an abrasive or heat treatment, by flaming, by grinding or by carding. Thus, it is possible to obtain bristles the end of which is shaped at the pinhead or tapered, which increases the product taking capacity of the applicator, and therefore its autonomy of application.

L'extrémité libre de l'applicateur peut être plate, arrondie ou coupée en pente.The free end of the applicator can be flat, rounded or sloped.

Avantageusement, le matériau thermoplastique peut contenir un agent modifiant son état de surface et/ou ses caractéristiques de glissement et/ou réduisant sa mouillabilité à l'eau et/ou au solvant. Cet agent peut être présent dans une proportion comprise entre 0,2% et 15% en poids, et de préférence entre 0,3% et 5% en poids.Advantageously, the thermoplastic material may contain an agent modifying its surface condition and / or its sliding characteristics and / or reducing its wettability with water and / or solvent. This agent can be present in a proportion of between 0.2% and 15% by weight, and preferably between 0.3% and 5% by weight.

Cet agent de glissement est choisi, de préférence, dans le groupe formé par le polytétrafluoroéthylène, le nitrure de bore, le bisulfure de molybdène, le graphite, les silicones, le fullerène, le talc.This slip agent is preferably chosen from the group formed by polytetrafluoroethylene, boron nitride, molybdenum disulphide, graphite, silicones, fullerene, talc.

L'applicateur présentant les caractéristiques qui viennent d'être décrites convient particulièrement pour l'application d'un vernis à ongles, d'un fard liquide ou d'une teinture capillaire, notamment d'un vernis à viscosité élevée. Dans le cas d'un vernis, celui-ci peut être une composition comportant ou non du toluène ou du formol ; il peut comporter, également, un système solvant comprenant de l'eau et/ou des alcools.The applicator having the characteristics which have just been described is particularly suitable for the application of a nail varnish, a liquid make-up or a hair dye, in particular a high viscosity varnish. In the case of a varnish, this can be a composition containing or not toluene or formalin; it can also include a solvent system comprising water and / or alcohols.

La présente invention se rapporte également à un ensemble d'application de vernis à ongles, constitué d'un réservoir, généralement en verre, muni d'un goulot et d'un manchon solidaire à une tige munie d'un organe d'application, immergé en position de stockage dans un vernis à ongles contenu dans ce réservoir, qui est caractérisé en ce qu'il est équipé d'un applicateur, tel que défini précédemment.The present invention also relates to an assembly for applying nail varnish, consisting of a reservoir, generally made of glass, provided with a neck and a sleeve integral with a rod provided with an application member, immersed in the storage position in a nail varnish contained in this tank, which is characterized in that it is equipped with an applicator, as defined above.

L'invention consiste, mis à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question après, à propos d'exemples de réalisations décrits avec référence aux dessins annexés, mais qui ne sont nullement limitatifs.The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below, with regard to examples of embodiments described with reference to the appended drawings, but which are by no means limiting.

La figure 1 est une vue simplifiée en élévation d'un ensemble de vernis à ongles conforme à l'invention.Figure 1 is a simplified elevational view of a set of nail varnishes according to the invention.

Les figures 2 à 6 représentent différentes réalisations d'un applicateur à tige flexible conforme à l'invention.Figures 2 to 6 show different embodiments of a flexible rod applicator according to the invention.

Les figures 7 à 14 sont des schémas de différentes sections transversales possibles des poils.Figures 7 to 14 are diagrams of different possible cross sections of the bristles.

La figure 15 montre un poil présentant une légère ondulation.Figure 15 shows a hair with a slight undulation.

Les figures 16 à 18 illustrent des sections transversales possibles, montrant le plan d'implantation de l'organe d'application.Figures 16 to 18 illustrate possible cross sections, showing the layout of the applicator member.

La figure 19 montre un applicateur conforme à l'invention en cours d'application.Figure 19 shows an applicator according to the invention during application.

En se reportant à la figure 1 des dessins, on peut voir un ensemble de vernis à ongles comprenant un pinceau (1) pour l'application du vernis, le pinceau (1) étant muni d'une touffe (2) de poils (3), fixée à une extrémité libre (5a) d'une tige (5) flexible et orientée sensiblement suivant la direction axiale de la tige. La tige flexible et les poils sont réalisés en un seul matériau thermoplastique, par exemple en polyéthylène de haute ou basse densité (PEHD ou PEBD). Ce sous-ensemble tige/poils peut être obtenu en une seule étape, par exemple par injection-moulage. Il est possible également, de réaliser la tige et la touffe en deux matériaux différents, chimiquement compatibles ; dans ce cas, on fixe la touffe de poils sur la tige par bi-injection ou surmoulage. Ainsi, un sous-ensemble tige/poils peut être réalisé par bi-injection, en injectant d'abord une tige en polyéthylène haute densité (PEHD), puis en injectant les poils de la touffe en élastomère de polyéthylène ou de polyéther bloc amide.Referring to Figure 1 of the drawings, one can see a set of nail polish comprising a brush (1) for applying the varnish, the brush (1) being provided with a tuft (2) of bristles (3 ), fixed to a free end (5a) of a flexible rod (5) and oriented substantially in the axial direction of the rod. The flexible rod and the bristles are made of a single thermoplastic material, for example high or low density polyethylene (HDPE or LDPE). This rod / bristle sub-assembly can be obtained in a single step, for example by injection molding. It is also possible to make the stem and the tuft in two different, chemically compatible materials; in this case, the tuft of hairs is fixed to the stem by bi-injection or overmolding. Thus, a rod / hair sub-assembly can be produced by bi-injection, by first injecting a rod in high density polyethylene (HDPE), then by injecting the hairs of the tuft in polyethylene or polyether block amide elastomer.

La tige (5) est cylindrique d'un diamètre d'environ 2,5 à 5 mm. Sa longueur est notamment de 4 cm. Une zone centrale (51), de plus faible section, pouvant aller de 0,2 à 1,8 mm, est prévue sur cette tige, lui conférant une flexibilité déterminée, voisine de celle de la touffe (2) de poils (3). Cette zone (51) apparaît mieux sur la figure 2 et peut avoir une longueur comprise dans la gamme allant de 2 à 20 mm. Un manchon cylindrique (6) est solidaire de l'autre extrémité (5b) de la tige (5) opposée à la touffe (2), cette extrémité (5b) étant conformée en forme de capsule de fixation introduite à force dans le manchon (6). Ce manchon (6) sert d'organe de manoeuvre du pinceau. Il sert également de bouchon destiné, notamment, à être vissé sur le goulot (13) d'un flacon (11) de vernis. Le vernis porte la référence (12).The rod (5) is cylindrical with a diameter of about 2.5 to 5 mm. Its length is in particular 4 cm. A central zone (51), of smaller section, which can range from 0.2 to 1.8 mm, is provided on this rod, giving it a determined flexibility, close to that of the tuft (2) of bristles (3) . This zone (51) appears better in FIG. 2 and can have a length comprised in the range going from 2 to 20 mm. A cylindrical sleeve (6) is integral with the other end (5b) of the rod (5) opposite the tuft (2), this end (5b) being shaped like a fixing capsule forced into the sleeve ( 6). This sleeve (6) serves as a member for operating the brush. It also serves as a stopper intended, in particular, to be screwed onto the neck (13) of a bottle (11) of varnish. The varnish has the reference (12).

Les figures 2 à 6 illustrent différents exemples de réalisation d'un pinceau muni d'une tige flexible comportant des poils moulés intégralement avec la tige.Figures 2 to 6 illustrate different embodiments of a brush provided with a flexible rod having bristles molded integrally with the rod.

Ainsi, la figure 2 montre, en vue agrandie, le pinceau représenté à la figure 1, dont la tige flexible (5) est cylindrique et munie d'une première extrémité (5a) comportant un plan d'implantation (8) pour une touffe (2) de poils (3). Une seconde extrémité (5b) de la tige est conformée en capsule de fixation, destinée à être introduite à force dans le manchon (6) pour solidariser celui-ci avec la tige flexible. La tige est cylindrique et est avantageusement réalisée en PEHD (polyéthylène de haute densité), comportant une zone (51) de plus faible diamètre, conférant à la tige une flexibilité déterminée et s'étendant quasiment sur toute la longueur de la tige. La tige a une section normale d'environ 4,0 à 20 mm, et la zone (51) a une section d'environ 0,2 à 1,8 mm. La zone (51) de plus faible section est une section choisie de sorte que le rapport S/s est compris entre 2 et 100, s étant la plus petite et S la section la plus importante.Thus, Figure 2 shows, in enlarged view, the brush shown in Figure 1, whose flexible rod (5) is cylindrical and provided with a first end (5a) having a layout plane (8) for a tuft (2) of hairs (3). A second end (5b) of the rod is shaped as a fixing capsule, intended to be forced into the sleeve (6) to secure the latter with the flexible rod. The rod is cylindrical and is advantageously made of HDPE (high density polyethylene), comprising a zone (51) of smaller diameter, giving the rod a determined flexibility and extending almost over the entire length of the rod. The rod has a normal section of about 4.0 to 20 mm, and the area (51) has a section of about 0.2 to 1.8 mm. The zone (51) with the smallest section is a section chosen so that the S / s ratio is between 2 and 100, s being the smallest and S the most important section.

La figure 3 montre un pinceau, dont la tige (5) est formée, dans sa majeure partie, par une bande (52) plate, en forme de languette allongée.FIG. 3 shows a paintbrush, the rod (5) of which is formed, for the most part, by a flat strip (52), in the form of an elongated tongue.

La figure 4 montre un pinceau, dont la tige (5) est formée, en partie, par deux bandes (53) agencées en deux hélices enchevêtrées formant une spirale à double entrée.FIG. 4 shows a paintbrush, the rod (5) of which is formed, in part, by two bands (53) arranged in two entangled helices forming a double entry spiral.

La figure 5 montre un pinceau, dont la tige (5) est formée, dans sa majeure partie, par une bande (54) plate conformée en "accordéon" ou comportant des ondulations.Figure 5 shows a brush, the rod (5) is formed, for the most part, by a strip (54) flat shaped "accordion" or having corrugations.

Le pinceau de la figure 6 a sensiblement la même conformation que celui de la figure 2, à l'exception près que la tige (5) est cylindrique, et qu'elle comporte une fente longitudinale (55), pour assurer la flexibilité de la tige.The brush of Figure 6 has substantially the same conformation as that of Figure 2, except that the rod (5) is cylindrical, and that it has a longitudinal slot (55), to ensure the flexibility of the rod.

On crée ainsi des réserves capillaires au produit à appliquer, permettant de régler la charge en produit en fonction de sa viscosité.Capillary reserves are thus created for the product to be applied, making it possible to adjust the load of product as a function of its viscosity.

Comme visible sur les figures 7 à 14, les sections transversales des poils (3) sont inscrites dans un cercle (φ) de diamètre compris entre 0,2 et 1,5 mm ; de préférence, la section est choisie dans la gamme de diamètre allant de 0,5 à 1 mm. Les sections des poils (3) peuvent avoir des formes variables : elles peuvent être circulaires pleines (3a), comme illustré sur la figure 7 ; circulaires creuses (3b), comme illustré sur la figure 8 ; en forme de C (3c), comme visible à la figure 9 ; en forme de H (3d), ou de V (3e), comme visible sur les figures 10 et 11 respectivement ; elles peuvent être de forme plate (3f), comme visible à la figure 12 ; ou polygonales, en particulier carrées, ou cruciformes (3g), comme visible à la figure 13 ; ou bien elles peuvent être trilobes, comportant des rainures capillaires (3i) comme illustré à la figure 14. Selon la réalisation de la figure 15, les poils (3k) ne peuvent pas être rectilignes et présenter, au moins sur une partie de leur longueur, de légères ondulations (7). L'extrémité libre au moins des poils peut être agencée également en forme effilée, obtenue par exemple par meulage ou par cardage. Ceci permet d'augmenter la capacité de prise de produit du pinceau, et donc son autonomie.As shown in Figures 7 to 14, the cross sections of the bristles (3) are inscribed in a circle (φ) with a diameter between 0.2 and 1.5 mm; preferably, the section is chosen from the diameter range from 0.5 to 1 mm. The sections of the bristles (3) can have variable shapes: they can be full circular (3a), as illustrated in FIG. 7; hollow circulars (3b), as illustrated in Figure 8; C-shaped (3c), as shown in Figure 9; H-shaped (3d), or V-shaped (3e), as shown in Figures 10 and 11 respectively; they can be flat (3f), as shown in Figure 12; or polygonal, in particular square, or cruciform (3g), as visible in Figure 13; or they can be three-lobed, comprising capillary grooves (3i) as illustrated in FIG. 14. According to the embodiment of FIG. 15, the bristles (3k) cannot be straight and present, at least over part of their length , slight undulations (7). The free end at least of the bristles can also be arranged in a tapered shape, obtained for example by grinding or by carding. This increases the product taking capacity of the brush, and therefore its autonomy.

Le pinceau (1) au niveau de sa touffe (2) peut présenter différentes formes de section transversale ; selon la figure 16 le plan d'implantation (8) de la touffe (2) est plate, de forme sensiblement rectangulaire. Selon la figure 17, ce plan (8) de la touffe est circulaire. Avantageusement, le pinceau peut avoir également une forme de tuile arrondie, un plan d'implantation correspondant étant visible à la figure 18. Un tel pinceau épouse mieux la forme de l'ongle.The brush (1) at its tuft (2) can have different shapes of cross section; according to Figure 16 the implantation plan (8) of the tuft (2) is flat, of substantially rectangular shape. According to Figure 17, this plane (8) of the tuft is circular. Advantageously, the brush can also have a rounded tile shape, a corresponding layout plan being visible in FIG. 18. Such a brush better matches the shape of the nail.

La figure 17 montre un pinceau à tige flexible, selon l'invention, en cours d'application d'un vernis (12) sur un ongle (O). On voit que la touffe (2) de poils et la partie flexible (51) de la tige (5) forment une courbe quasi-constante, sensiblement en arc de cercle, de sorte que la touffe (2) est au contact de l'ongle (O) de façon sensiblement tangentielle.FIG. 17 shows a brush with flexible rod, according to the invention, during the application of a varnish (12) on a nail (O). We see that the tuft (2) of bristles and the flexible part (51) of the rod (5) form an almost constant curve, substantially in an arc, so that the tuft (2) is in contact with the nail (O) substantially tangentially.

Lorsqu'on réalise un pinceau cylindrique conforme à la présente invention, le diamètre de la touffe (2) des poils (3) est généralement compris dans la gamme de 0,5 à 6 mm ; grâce à l'utilisation d'une tige flexible telle que décrite précédemment, on obtient un pinceau qui, lors de l'application, tire le vernis (12), au lieu de le pousser, comme un pinceau classique.When producing a cylindrical brush according to the present invention, the diameter of the tuft (2) of the bristles (3) is generally in the range of 0.5 to 6 mm; through the use of a flexible rod as described above, a brush is obtained which, during application, pulls the varnish (12), instead of pushing it, like a conventional brush.

Le pinceau conforme à la présente invention est facile à réaliser et ceci à un prix de revient avantageux.The brush according to the present invention is easy to produce and this at an advantageous cost price.

L'applicateur présentant les caractéristiques qui viennent d'être décrites convient particulièrement pour l'application d'un vernis à ongles (12), d'un fard liquide ou d'une teinture capillaire, notamment d'un vernis à viscosité élevée. Ce vernis peut être une composition comportant ou non, du toluène ou du formol ; ce vernis peut comporter, également, un système solvant comprenant de l'eau et/ou des alcools.The applicator having the characteristics which have just been described is particularly suitable for applying a nail varnish (12), a liquid make-up or a hair dye, in particular a varnish with high viscosity. This varnish can be a composition comprising or not, toluene or formalin; this varnish may also include a solvent system comprising water and / or alcohols.

La couche de vernis déposée par un tel applicateur est très homogène, épaisse, déposée de façon précise, et présente, après séchage, des propriétés d'adhésion améliorées. La surface a un aspect brillant. Le vernis peut être déposé en une seule fois ou éventuellement en deux fois, la seconde couche pouvant être déposée sur la première, avant que celle ci ne soit sèche. Il n'y a pas de formation de stries.The layer of varnish deposited by such an applicator is very homogeneous, thick, deposited in a precise manner, and exhibits, after drying, improved adhesion properties. The surface has a shiny appearance. The varnish can be deposited all at once or possibly twice, the second layer being able to be deposited on the first, before the latter is dry. There is no streak formation.
