Description

La présente invention concerne les dispositifs pour l'application d'un produit cosmétique, y compris de soin, et plus particulièrement mais non exclusivement, ceux destinés à l'application d'un vernis à ongles ou d'un eye-liner.The present invention relates to devices for the application of a cosmetic product, including care, and more particularly but not exclusively, those for the application of a nail polish or an eyeliner.

Le brevet US 6 033 143 décrit des applicateurs de vernis à ongles comportant une tige ayant une portion flexible. La portion flexible de la tige ne s'étend pas autour de l'organe d'application.The patent US 6,033,143 discloses nail polish applicators having a shaft having a flexible portion. The flexible portion of the rod does not extend around the applicator member.

Les flacons de vernis à ongles rencontrés sur le marché présentant diverses contenances, le plus souvent comprises entre 7 et 14 ml. Les applicateurs associés comprennent une tige avec un organe d'application, notamment un pinceau, à une extrémité.The bottles of nail polish found on the market with various capacities, most often between 7 and 14 ml. The associated applicators comprise a rod with an applicator member, in particular a brush, at one end.

Pour les flacons de contenance relativement grande, par exemple 12 ml ou plus, la hauteur du corps du flacon permet d'utiliser une tige relativement longue. Par contre, pour les flacons de plus petite contenance, la hauteur du corps du flacon est généralement moindre et la tige doit alors être plus courte si l'on veut maintenir les poils du pinceau suffisamment longs pour ne pas perdre en souplesse et en qualité d'application. Une tige courte peut nuire au confort lors de l'application et à l'esthétique.For bottles of relatively large capacity, for example 12 ml or more, the height of the body of the bottle allows to use a relatively long rod. On the other hand, for bottles of smaller capacity, the height of the body of the bottle is generally less and the stem must then be shorter if one wants to keep the brush hairs long enough not to lose in flexibility and quality. 'application. A short stem can affect comfort during application and aesthetics.

La longueur des poils du pinceau ne peut être raccourcie sauf à rendre le pinceau plus rigide et risquer de former des stries sur l'ongle au moment de l'application.The length of the bristles of the brush can not be shortened except to make the brush stiffer and risk forming streaks on the nail at the time of application.

Il existe un besoin pour bénéficier d'un applicateur permettant une application convenable du produit, tout en ayant une esthétique plaisante, et qui soit simple à fabriquer et à utiliser, même lorsqu'associé à un récipient de faible contenance, le cas échéant.There is a need for an applicator for proper application of the product, while having a pleasing aesthetic, and which is simple to manufacture and use, even when associated with a low capacity container, where appropriate.

L'invention vise notamment à répondre à ce besoin.The invention aims in particular to meet this need.

Elle y parvient grâce à un applicateur pour appliquer un produit sur une surface kératinique, comportant :

  • une tige,
  • un organe d'application porté par la tige,
la tige comportant une première portion déformable qui comporte une paroi déformable qui entoure au moins partiellement l'organe d'application, cette première portion étant agencée pour pouvoir se déformer au moins partiellement en réponse à une déformation de l'organe d'application lors de l'application.It achieves this through an applicator for applying a product to a keratinous surface, comprising:
  • a rod,
  • an application member carried by the stem,
the rod comprising a first deformable portion which comprises a deformable wall which at least partially surrounds the applicator member, this first portion being arranged to be able to deform at least partially in response to a deformation of the applicator member during the application.

Grâce à l'invention, on peut bénéficier d'un organe d'application relativement souple tout en donnant l'impression d'avoir une longueur de tige relativement grande, ce qui est avantageux d'un point de vue esthétique.Thanks to the invention, one can benefit from a relatively flexible application member while giving the impression of having a relatively large rod length, which is advantageous from an aesthetic point of view.

La première portion précitée étant capable de se déformer de manière sensible en réponse à une flexion de l'organe d'application, la longueur apparente de celui-ci peut être moindre sans perdre en souplesse ni en confort ou précision d'application.The aforesaid first portion being capable of deforming substantially in response to bending of the applicator member, the apparent length thereof may be less without loss of flexibility or comfort or accuracy of application.

Cette première portion peut être réalisée dans une partie distale de la tige qui peut se raccorder à une partie proximale, laquelle peut être éventuellement sensiblement non déformable à l'application.This first portion may be made in a distal portion of the rod that can be connected to a proximal portion, which may be substantially non-deformable to the application.

Dans le cas d'un organe d'application constitué par un pinceau, les poils peuvent par exemple présenter une longueur apparente de 10 mm tout en offrant les performances et le confort à l'application d'un applicateur conventionnel dont la longueur apparente des poils serait plus grande, par exemple de 10 % à 300 %, par exemple égale à 17 mm.In the case of an applicator member constituted by a brush, the bristles may for example have an apparent length of 10 mm while offering the performance and comfort to the application of a conventional applicator whose apparent length of hair would be larger, for example from 10% to 300%, for example equal to 17 mm.

Par ailleurs, la première portion peut contribuer à imposer la manière dont l'organe d'application se déforme à l'application, de sorte que l'utilisateur peut gagner en précision, par exemple pour suivre le contour des ongles.Moreover, the first portion can contribute to imposing the manner in which the application member deforms on application, so that the user can gain in precision, for example to follow the outline of the nails.

La partie distale peut encore être rapportée sur la partie proximale, les parties proximale et distale pouvant être notamment assemblées par encliquetage, insertion à force, collage ou soudure.The distal portion can also be reported on the proximal portion, the proximal and distal portions being able to be assembled in particular by snap-fitting, insertion force, gluing or welding.

Les parties proximale et distale peuvent être réalisées dans un même matériau, ou encore au moins partiellement dans deux matériaux respectifs différents.The proximal and distal portions may be made of the same material, or at least partially in two different respective materials.

La première portion, tout comme la partie distale, peut être réalisée au moins partiellement dans un matériau élastomère.The first portion, like the distal portion, can be made at least partially in an elastomeric material.

La première portion peut être réalisée au moins partiellement dans l'un des matériaux suivants : silicone, EPDM, PU, SIS, SEBS, SBS, EVA, polyéther bloc, polyester, cette liste n'étant pas limitative.The first portion can be made at least partially in one of the following materials: silicone, EPDM, PU, SIS, SEBS, SBS, EVA, polyether block, polyester, this list not being limiting.

La tige peut comporter une deuxième portion, les première et deuxième portions pouvant former la tige, cette deuxième portion pouvant être réalisée au moins partiellement dans l'un des matériaux suivants : PEHD, PEBD, PP, POM, PA, PET, PBT, cette liste n'étant pas limitative.The rod may comprise a second portion, the first and second portions being able to form the rod, this second portion being able to be made at least partially in one of the following materials: HDPE, LDPE, PP, POM, PA, PET, PBT, this list not being limiting.

La tige peut comporter au moins une fente s'étendant sur au moins une partie de la longueur de la première portion. Une telle fente peut favoriser la déformabilité de la première portion, et permettre par exemple l'emploi d'une matière moins souple.The stem may include at least one slot extending over at least a portion of the length of the first portion. Such a slot can promote the deformability of the first portion, and allow for example the use of a less flexible material.

La première portion peut s'étendre autour de l'organe d'application de manière continue ou discontinue, et notamment entourer circonférentiellement entièrement ou partiellement l'organe d'application.The first portion may extend around the applicator member in a continuous or discontinuous manner, and in particular circumferentially completely or partially surround the applicator member.

La première portion peut être en contact ou non avec l'organe d'application.The first portion may or may not be in contact with the application member.

La tige peut comporter deux ouvertures opposées s'étendant sur au moins une partie de la longueur de la première portion, à partir de l'extrémité libre de celle-ci. Ces ouvertures peuvent améliorer la déformabilité de la première portion et/ou permettre à l'organe d'application de se déformer d'une certaine manière à l'application, notamment lorsque l'organe d'application est un pinceau.The rod may have two opposing openings extending over at least a portion of the length of the first portion from the free end thereof. These openings may improve the deformability of the first portion and / or allow the applicator member to deform in a certain way to the application, especially when the applicator member is a brush.

L'organe d'application s'étend au moins partiellement hors de la première portion, et peut par exemple s'étendre majoritairement ou non hors de la première portion. La longueur de la partie de l'organe d'application engagée à l'intérieur de la première portion peut par exemple correspondre à au moins un quart, voire au moins un tiers, de la longueur totale de l'organe d'application, notamment lorsque l'organe d'application est un faisceau de poils.The applicator member extends at least partially out of the first portion, and may for example extend predominantly or not outside the first portion. The length of the portion of the applicator member engaged inside the first portion may, for example, correspond to at least a quarter, or even at least one third, of the total length of the applicator member, in particular when the applicator member is a bundle of bristles.

L'organe d'application peut être fixé à la partie proximale ou à la partie distale.The applicator member may be attached to the proximal portion or the distal portion.

La première portion peut être plus facilement déformable selon au moins une direction de déformation préférentielle.The first portion may be more easily deformable in at least one direction of preferential deformation.

La première portion peut présenter, en l'absence d'application, une section transversale extérieure non constante, par exemple définie par une paroi s'amincissant en rapprochement de l'extrémité libre de la tige. Une section transversale intérieure ou extérieure de la première portion peut présenter une forme choisie parmi les suivantes : circulaire, non circulaire, notamment oblongue, ovale, elliptique, polygonale, notamment carrée, rectangulaire, réniforme, crenelée, en forme d'étoile, avec une ou plusieurs gorges, le cas échéant.The first portion may have, in the absence of application, a non-constant outer cross section, for example defined by a wall tapering towards the free end of the rod. An inner or outer transverse section of the first portion may have a shape selected from the following: circular, non-circular, in particular oblong, oval, elliptical, polygonal, in particular square, rectangular, kidney-shaped, crenellated, star-shaped, with a shape or several throats, if any.

La première portion peut comporter une paroi dont l'épaisseur peut être comprise entre 0,3 et 0,8 mm, par exemple. Quelle que soit sa valeur, l'épaisseur peut être constante ou variable, notamment dans le sens longitudinal, en particulier diminuant en rapprochement de l'extrémité libre de la première portion.The first portion may comprise a wall whose thickness may be between 0.3 and 0.8 mm, for example. Whatever its value, the thickness may be constant or variable, especially in the longitudinal direction, in particular decreasing closer to the free end of the first portion.

La longueur de la première portion peut être comprise par exemple entre 1 et 12 mm, notamment entre 2 et 8 mm.The length of the first portion may be for example between 1 and 12 mm, in particular between 2 and 8 mm.

La tige peut comporter, sur au moins une partie de sa longueur, au moins une rainure, notamment deux rainures situées à l'opposé l'une de l'autre. Au moins une rainure peut s'étendre sur une majeure partie de la longueur de la première portion de la tige, notamment sur sensiblement toute sa longueur.The rod may comprise, over at least a portion of its length, at least one groove, in particular two grooves located opposite one another. At least one groove may extend over a major part of the length of the first portion of the rod, in particular over substantially its entire length.

La longueur apparente de l'organe d'application peut être comprise entre 2 et 7 mm par exemple, et notamment peut être de l'ordre de 5 mm environ.The apparent length of the applicator member may be between 2 and 7 mm for example, and in particular may be of the order of about 5 mm.

L'organe d'application peut comporter l'un au moins des éléments suivants : un faisceau de poils, un feutre, un revêtement de flocage, une mousse. L'organe d'application peut comporter un faisceau de poils formant un pinceau, dont la section transversale peut être plate ou ronde. L'organe d'application peut comporter au moins une pointe, éventuellement floquée.The applicator member may comprise at least one of the following elements: a bundle of bristles, a felt, a flocking coating, a foam. The applicator member may comprise a bundle of bristles forming a brush, whose cross section may be flat or round. The applicator member may comprise at least one tip, possibly flocked.

L'organe d'application peut comporter des poils naturels ou synthétiques, creux ou pleins, à rainure capillaire, de section polygonale ou non, circulaire ou non, ou un mélange de poils de différentes natures et/ou formes.The applicator member may comprise natural or synthetic bristles, hollow or solid, with a capillary groove, of polygonal or non-circular section, circular or not, or a mixture of bristles of different natures and / or shapes.

La partie proximale peut se raccorder, d'un côté opposé à la partie distale, à un organe de préhension. Ce dernier peut comporter des moyens de fixation sur un récipient, notamment un filetage.The proximal portion may be connected, on a side opposite the distal portion, to a gripping member. The latter may comprise fixing means on a container, in particular a thread.

L'invention a encore pour objet un dispositif de conditionnement et d'application d'un produit cosmétique ou de soin sur une surface kératinique, comportant :

  • un applicateur tel que défini plus haut, et
  • un récipient contenant le produit.
The invention further relates to a device for packaging and applying a cosmetic or care product to a keratinous surface, comprising:
  • an applicator as defined above, and
  • a container containing the product.

L'applicateur peut être agencé de manière à pouvoir être fixé de manière amovible sur le récipient.The applicator may be arranged to be removably attached to the container.

Le récipient peut comporter un essoreur.The container may include a wiper.

Le produit peut être un produit à appliquer sur les ongles, notamment un vernis à ongles.The product may be a product to be applied to the nails, especially a nail polish.

La contenance du récipient peut être comprise entre 2 et 12 ml, notamment entre 5 et 9 ml, voire être de 7 ml environ.The capacity of the container may be between 2 and 12 ml, in particular between 5 and 9 ml, or even be about 7 ml.

L'invention n'est pas limitée à un applicateur de vernis à ongles, et peut notamment s'appliquer à un applicateur d'eye-liner. Dans ce cas, l'organe d'application peut être par exemple un pinceau ou autre chose qu'un pinceau, notamment une pointe feutre, une pointe en matière plastique floquée ou encore une pointe en mousse. La présence de la première portion déformable peut permettre de diminuer la sensation de dureté à l'application sur l'oeil.The invention is not limited to a nail polish applicator, and may especially apply to an eyeliner applicator. In this case, the application member may be for example a brush or something other than a brush, including a felt tip, a flocked plastic tip or a foam tip. The presence of the first deformable portion can reduce the sensation of hardness on application to the eye.

L'invention a encore pour objet un procédé de fabrication d'un applicateur pour appliquer un produit sur une surface kératinique, comportant les étapes suivantes :

  • fournir une tige comportant un manchon coulissant, ce manchon étant dans une position d'attente libérant l'accès à une extrémité de la tige,
  • fixer sur la tige à son extrémité un organe d'application,
  • faire coulisser sur la tige en direction de l'extrémité de celle-ci le manchon de manière à ce que celui-ci vienne recouvrir au moins partiellement l'organe d'application.
The invention also relates to a method of manufacturing an applicator for applying a product to a keratinous surface, comprising the following steps:

Au moins une partie du manchon peut être agencée pour pouvoir se déformer au moins partiellement en réponse à une déformation de l'organe d'application lors de l'application.At least a portion of the sleeve may be arranged to be able to deform at least partially in response to a deformation of the applicator member during application.

Le manchon peut être agencé pour s'immobiliser sur la tige par encliquetage ou friction au terme de son coulissement en direction de l'extrémité de la tige.The sleeve may be arranged to stop on the rod by snapping or friction at the end of its sliding towards the end of the rod.

L'invention a encore pour objet un applicateur pour appliquer un produit sur une surface kératinique, l'applicateur comportant :

  • une tige, et
  • un organe d'application associé à une extrémité distale de la tige,
dans lequel la tige comporte une portion s'étendant autour d'une partie au moins de l'organe d'application,

Le dispositif de conditionnement et d'application 1 représenté à la figure 1 comporte un récipient 2 et un applicateur 3 fixé de manière amovible sur le récipient 2.The packaging and application device 1 shown in FIG. 1 comprises a container 2 and an applicator 3 removably attached to the container 2.

Dans l'exemple considéré, le récipient 2 comporte en partie supérieure un col 4 fileté extérieurement, sur lequel peut se visser une capsule de fermeture 5 qui sert également d'organe de préhension pour l'applicateur 3.In the example considered, the container 2 comprises in the upper part an externally threaded neck 4, on which can be screwed a closure cap 5 which also serves as a gripping member for the applicator 3.

Le récipient 2 contient un vernis à ongles V dans l'exemple décrit, mais on ne sort pas du cadre de la présente invention lorsque le produit contenu dans le récipient est autre.The container 2 contains a nail varnish V in the example described, but it is not beyond the scope of the present invention when the product contained in the container is other.

L'applicateur 3 comporte une tige 6 que l'on a représenté isolément à la figure 2 et qui comporte à une extrémité un embout 8 destiné à sa fixation dans la capsule de fermeture 5 et à l'extrémité opposée un faisceau 10 de poils 11, de façon à constituer un pinceau.The applicator 3 comprises a rod 6 which has been shown in isolation in FIG. 2 and which has at one end an endpiece 8 intended to fix it in the closure cap 5 and at the opposite end a bundle 10 of bristles 11 , so as to constitute a brush.

Plus particulièrement, dans l'exemple considéré, la tige 6 comporte une partie distale 6a et une partie proximale 6b réalisées dans des matériaux différents, la partie proximale 6b comportant une partie cylindrique de révolution autour de l'axe X, cette partie cylindrique se raccordant à l'embout 8 par une partie tronconique 14.More particularly, in the example considered, the rod 6 comprises a distal portion 6a and a proximal portion 6b made of different materials, the proximal portion 6b having a cylindrical portion of revolution about the X axis, this cylindrical portion being connected at the end 8 by a frustoconical portion 14.

L'extrémité de la partie proximale 6b adjacente à la partie distale 6a comporte un logement 16 au fond duquel est fixé, par agrafage par exemple, le faisceau 10 de poils, ce dernier étant par exemple plié en deux et fixé à mi-longueur par une agrafe mise en place dans le fond du logement 16.The end of the proximal portion 6b adjacent to the distal portion 6a comprises a housing 16 at the bottom of which is fixed, for example stapling, the bundle 10 of bristles, the latter being for example folded in half and fixed at mid-length by a staple placed in the bottom of the housing 16.

La partie distale 6a définit un logement 17 d'axe X, ouvert à ses deux extrémités axiales, qui est traversé par le faisceau 10.The distal portion 6a defines an X-axis housing 17, open at its two axial ends, through which the beam 10 passes.

La première portion 12 est définie par la portion de la tige 6 qui s'étend autour de l'organe d'application 10 et qui peut se déformer au moins partiellement en réponse à une déformation de l'organe d'application lors de l'application. Dans l'exemple illustré, la première portion 12 s'étend sur toute la longueur de la partie distale 6a. Le reste de la tige définit la deuxième portion 13.The first portion 12 is defined by the portion of the rod 6 which extends around the applicator member 10 and which can deform at least partially in response to a deformation of the applicator member during the application. In the example shown, the first portion 12 extends over the entire length of the distal portion 6a. The rest of the rod defines the second portion 13.

Cette deuxième portion 13 peut être entièrement non déformable ou en partie non déformable. Les poils peuvent être fixés dans la deuxième portion 13 non déformable, comme c'est le cas dans l'exemple considéré.This second portion 13 may be entirely non-deformable or partly non-deformable. The bristles may be fixed in the second portion 13 non-deformable, as is the case in the example.

Dans l'exemple considéré, la paroi de la première portion 12 s'amincit en direction de l'extrémité libre 19 de la tige 6 et la première portion 12 présente des sections transversales intérieure et extérieure toutes deux circulaires, comme on peut le voir sur la figure 6. D'autres formes de sections sont possibles, comme cela sera illustré plus loin.In the example considered, the wall of the first portion 12 tapers toward the free end 19 of the rod 6 and the first portion 12 has both inner and outer circular cross sections, as can be seen on Figure 6. Other forms of sections are possible, as will be illustrated below.

Dans l'exemple considéré, la partie distale 6a est réalisée dans une matière plastique plus souple que celle dans laquelle est réalisée la partie proximale 6b. La partie distale 6a est par exemple réalisée dans un élastomère, lequel peut être surmoulé à l'extrémité de la partie proximale 6b, notamment un élastomère thermoplastique.In the example considered, the distal portion 6a is made of a softer plastic material than that in which the proximal portion 6b is made. The distal portion 6a is for example made in an elastomer, which may be overmoulded at the end of the proximal portion 6b, in particular a thermoplastic elastomer.

L'applicateur 3 peut par exemple être fabriqué de la façon suivante.The applicator 3 may for example be manufactured in the following manner.

On moule la tige 6 en moulant tout d'abord la partie proximale 6b, puis en surmoulant sur la partie proximale 6b la partie distale 6a. On fixe ensuite les poils sur la partie proximale 6b.The rod 6 is molded by first molding the proximal portion 6b and then overmolding on the proximal portion 6b the distal portion 6a. The bristles are then attached to the proximal portion 6b.

Lors de l'utilisation, comme illustré sur la figure 3, le faisceau 10 peut fléchir au contact de la surface sur laquelle le produit doit être appliqué, par exemple l'ongle, et la première portion 12 peut accompagner dans une certaine mesure la déformation du faisceau 10, grâce à sa déformabilité, tandis que la deuxième portion 13 présente une forme sensiblement inchangée.In use, as illustrated in FIG. 3, the bundle 10 can bend in contact with the surface on which the product is to be applied, for example the fingernail, and the first portion 12 can accompany to a certain extent the deformation. beam 10, thanks to its deformability, while the second portion 13 has a substantially unchanged shape.

La première portion 12 participe ainsi au confort à l'application et permet d'avoir une longueur de tige 6 apparente, s'étendant hors de la capsule de fermeture 5 lorsque l'applicateur est observé de côté, suffisamment longue pour être plaisante sur le plan esthétique. Cette longueur apparente facilite également l'application précise du produit en évitant que la capsule de fermeture ne gêne l'observation, lors de l'application de la surface sur laquelle le produit doit être appliqué.The first portion 12 thus contributes to the comfort of the application and makes it possible to have an apparent length of rod 6, extending out of the closure cap 5 when the applicator is observed from the side, long enough to be pleasant on the aesthetic plan. This apparent length also facilitates the precise application of the product by avoiding that the closure cap interferes with the observation, when applying the surface on which the product is to be applied.

La première portion 12 permet également au faisceau 10 de se comporter comme s'il était plus long que ce qu'il ne paraît, grâce au fait que la première portion 12 peut accompagner dans une certaine mesure la déformation de la partie du faisceau 10 qui s'étend dans le logement 17.The first portion 12 also allows the beam 10 to behave as if it were longer than it appears, thanks to the fact that the first portion 12 can accompany to a certain extent the deformation of the portion of the beam 10 which extends into the housing 17.

La première portion 12 peut se déformer en fléchissant, c'est-à-dire en se déformant de telle sorte que son axe longitudinal devienne curviligne et non plus confondu avec l'axe X. La première portion 12 peut aussi se déformer en changeant de section, notamment en prenant une section s'aplatissant, ce qui peut favoriser l'étalement des poils du faisceau 10, notamment un écartement en éventail.The first portion 12 can be deformed by bending, that is to say by deforming so that its longitudinal axis becomes curvilinear and no longer coincides with the X axis. The first portion 12 can also be deformed by changing the section, including taking a flattening section, which can promote the spreading of the bristles of the beam 10, including a fan spacing.

Une fois que l'application cesse, la première portion 12 peut reprendre par mémoire de forme, grâce à son élasticité propre, sa forme initiale, et notamment avoir son axe longitudinal à nouveau rectiligne et confondu avec l'axe X.Once the application ceases, the first portion 12 can resume shape memory, thanks to its own elasticity, its original shape, and in particular have its longitudinal axis again rectilinear and coincident with the X axis.

Diverses modifications peuvent être apportées à l'applicateur sans que l'on ne sorte du cadre de la présente invention.Various modifications can be made to the applicator without departing from the scope of the present invention.

Par exemple, le faisceau 10 peut être implanté entièrement dans la partie distale 6a, comme on le voit sur la figure 4. Dans cet exemple, la première portion 12 ne s'étend que sur une partie de la longueur de la partie distale 6a, laquelle est réalisée entièrement en matériau élastomère.For example, the beam 10 may be fully implanted in the distal portion 6a, as seen in FIG. 4. In this example, the first portion 12 extends only over a portion of the length of the distal portion 6a, which is made entirely of elastomeric material.

La deuxième portion 13 s'étend alors au moins partiellement sur la partie distale 6a réalisée en élastomère.The second portion 13 then extends at least partially over the distal portion 6a made of elastomer.

Les parties distale et proximale, lorsqu'elles sont réalisées dans des matériaux différents, peuvent être assemblées de diverses autres manières que par surmoulage de matière, et notamment peuvent être assemblées par complémentarité de forme comme illustré sur la figure 5, par exemple en réalisant à une extrémité de la partie distale 6a une forme mâle 20 configurée pour s'engager dans un logement 21 de forme complémentaire de la partie proximale 6b.The distal and proximal parts, when they are made of different materials, can be assembled in various other ways than by overmoulding of material, and in particular can be assembled by complementarity of shape as illustrated in FIG. 5, for example by realizing one end of the distal portion 6a has a male shape 20 configured to engage a housing 21 of complementary shape to the proximal portion 6b.

Dans l'exemple de la figure 2, la première portion 12 comporte une paroi de section transversale circulaire qui entoure le faisceau 10. En l'absence d'application, cette paroi peut présenter, en variante, une section transversale non circulaire, par exemple sensiblement ovale comme illustré à la figure 7.In the example of FIG. 2, the first portion 12 has a circular cross-section wall that surrounds the bundle 10. In the absence of application, this wall may, in a variant, have a non-circular cross-section, for example substantially oval as shown in Figure 7.

La première portion 12 peut encore présenter une section transversale de forme polygonale, par exemple carrée ou rectangulaire comme illustré sur les figures 8 et 9, réniforme comme illustré sur la figure 10, étoilée comme illustré sur la figure 11 ou crénelée, comme représenté sur la figure 12.The first portion 12 may also have a cross-section of polygonal shape, for example square or rectangular as illustrated in Figures 8 and 9, reniform as illustrated in Figure 10, starred as illustrated in Figure 11 or crenellated, as shown in FIG. figure 12.

La tige 6 peut être réalisée avec par exemple une rainure longitudinale 23, laquelle peut s'étendre sur tout ou partie de la longueur de la tige et notamment sur une fraction de la longueur de celle-ci à partir de son extrémité libre 19. La rainure 23 peut notamment s'étendre seulement sur la première portion 12, par exemple sur une majeure partie de celle-ci, ou sur une partie au moins de la partie distale 6a.The rod 6 may be made with for example a longitudinal groove 23, which may extend over all or part of the length of the rod and in particular on a fraction of the length thereof from its free end 19. The groove 23 may in particular extend only on the first portion 12, for example on a major part thereof, or on at least part of the distal part 6a.

On voit sur la figure 14 que la tige 6, notamment sa première portion 12, peut présenter des sections transversales intérieure et extérieure n'ayant pas la même forme.It can be seen in FIG. 14 that the rod 6, in particular its first portion 12, may have internal and external transverse sections that do not have the same shape.

Plus précisément, la tige 6 peut être réalisée, notamment sur une certaine partie de sa longueur à partir de son extrémité libre 19, avec une section transversale extérieure de forme générale oblongue et avec deux rainures 23 opposées, comme on peut le voir sur la figure 14. La section transversale intérieure peut être par exemple rectangulaire, de sorte que la paroi de la première portion 12 présente des variations d'épaisseur autour du logement 17 traversé par le faisceau 10 de poils.More specifically, the rod 6 can be made, in particular over a certain part of its length from its free end 19, with an outer cross section of generally oblong shape and with two opposite grooves 23, as can be seen in FIG. 14. The inner cross section may for example be rectangular, so that the wall of the first portion 12 has variations in thickness around the housing 17 through which the bundle 10 of bristles.

Les rainures 23 peuvent servir à canaliser le produit qui s'écoule, après retrait de l'applicateur du récipient, sur la tige 6 en direction de son extrémité libre 19 vers une ou plusieurs zones prédéfinies du faisceau 10, notamment dans une région centrale de celui-ci, afin d'améliorer le confort à l'application et notamment la précision du maquillage.The grooves 23 may serve to channel the product which flows, after removal of the applicator from the container, on the rod 6 towards its free end 19 towards one or more predefined zones of the bundle 10, in particular in a central region of this one, to improve the comfort to the application and in particular the precision of the make-up.

On a illustré sur les figures 15 et 16 la possibilité pour la tige 6 de comporter à partir de son extrémité libre 19 deux ouvertures latérales diamétralement opposées 25, qui s'étendent par exemple sur une majeure partie de la première portion 12. Ces ouvertures 25 peuvent permettre aux poils 11 du faisceau 10 de s'écarter en éventail lors de l'application, en traversant les ouvertures 25.FIGS. 15 and 16 illustrate the possibility for the rod 6 to comprise, from its free end 19, two diametrically opposed lateral openings 25, which extend for example over a major part of the first portion 12. These openings 25 may allow the bristles 11 of the bundle 10 to fan away during application, by passing through the openings 25.

La forme de la section transversale de la première portion 12 peut définir au moins une direction préférentielle selon laquelle la première portion 12 peut se déformer. Par exemple, une section transversale de forme oblongue pourra fléchir plus facilement autour d'un axe qui est parallèle au grand axe de la section oblongue.The shape of the cross section of the first portion 12 may define at least one preferential direction in which the first portion 12 can deform. For example, an oblong cross-section may flex more easily about an axis that is parallel to the major axis of the oblong section.

Une section transversale réniforme peut donner au faisceau 10 une forme générale de tuile et lui permettre d'épouser plus facilement la forme bombée de l'ongle.A reniform cross-section can give the beam 10 a general shape of tile and allow it to marry more easily the convex shape of the nail.

La tige 6 peut être réalisée avec au moins une fente destinée à améliorer la déformabilité d'au moins une fraction de la longueur de la tige et notamment la déformabilité de sa première portion 12.The rod 6 can be made with at least one slot intended to improve the deformability of at least a fraction of the length of the rod and in particular the deformability of its first portion 12.

Sur la figure 17, on a représenté une tige 6 qui comporte une pluralité de fentes longitudinales 27 à bords jointifs, lesquelles sont réparties uniformément sur la circonférence de la première portion 12, et traversent toute l'épaisseur de sa paroi dans l'exemple considéré. En variante, les fentes 27 pourraient ne s'étendre que sur une partie de l'épaisseur de la paroi, notamment à partir de sa surface extérieure. Elles pourraient également ne pas être à bords jointifs.FIG. 17 shows a rod 6 which has a plurality of longitudinal slots 27 with contiguous edges, which are distributed uniformly over the circumference of the first portion 12, and pass through the entire thickness of its wall in the example considered. Alternatively, the slots 27 could extend only over a portion of the wall thickness, especially from its outer surface. They could also not be contiguous.

La tige 6 peut être réalisée, comme on le voit sur la figure 18, avec au moins une portion 30 en forme de soufflet, s'étendant entre des régions 31 et 32, capable par exemple de fléchir autour d'au moins un axe perpendiculaire à l'axe longitudinal X.The rod 6 can be made, as can be seen in FIG. 18, with at least one bellows-shaped portion 30 extending between regions 31 and 32, capable for example of flexing around at least one perpendicular axis to the longitudinal axis X.

La partie distale 6a de la tige 6 peut encore être en forme de bec de canard, comme on l'a représenté de façon schématique à la figure 30. L'extrémité de la partie distale 6a qui se raccorde à la partie proximale 6b de la tige 6 est de forme sensiblement circulaire et l'extrémité libre 19 de la partie distale 6a est de forme aplatie.The distal portion 6a of the rod 6 may also be in the form of a duckbill, as shown schematically in FIG. 30. The end of the distal portion 6a which connects to the proximal portion 6b of the rod 6 is substantially circular in shape and the free end 19 of the distal portion 6a is of flattened shape.

Dans la variante de réalisation illustrée à la figure 31, la tige 6 comporte une partie distale 6a constituée d'un manchon 40 pouvant coulisser le long de la partie proximale 6b de la tige.In the embodiment shown in Figure 31, the rod 6 has a distal portion 6a consists of a sleeve 40 slidable along the proximal portion 6b of the rod.

On a représenté à la figure 32 le manchon 40 dans une position d'attente sur la partie proximale 6b de la tige 6, permettant ainsi un accès aisé au logement 16 pour la fixation du faisceau 10 de poils 11 dans celui-ci.Figure 32 shows the sleeve 40 in a waiting position on the proximal portion 6b of the rod 6, thus allowing easy access to the housing 16 for fixing the bundle 10 of bristles 11 therein.

Après la mise en place du faisceau 10 de poils 11, le manchon 40 est déplacé par rapport à la partie proximale 6b de la tige 6 pour venir entourer une partie du faisceau 10. Le manchon 40 est maintenu dans sa position finale sur la partie proximale 6b de la tige 6 par exemple par encliquetage, grâce à un bourrelet annulaire 41 s'engageant dans une gorge annulaire 42 ménagée à l'extrémité de la partie proximale 6b de la tige 6.After placement of the bundle 10 of bristles 11, the sleeve 40 is moved relative to the proximal portion 6b of the rod 6 to surround a portion of the bundle 10. The sleeve 40 is held in its final position on the proximal portion 6b of the rod 6 for example by snapping, thanks to an annular bead 41 engaging in an annular groove 42 formed at the end of the proximal portion 6b of the rod 6.

Dans le cas notamment des exemples des figures 15, 17 et 18, la déformabilité de la première portion 12 peut être obtenue grâce à la présence des ouvertures 25, des fentes 27 ou du soufflet 30, et la première portion 12 peut présenter une déformabilité suffisante sans qu'il y ait besoin de réaliser celle-ci dans une matière élastomère, la première portion 12 pouvant être réalisée, le cas échéant, dans le même matériau que le reste de la tige. Toutefois, il est préférable, pour bénéficier de davantage de déformabilité encore, de réaliser la première portion 12 au moins partiellement dans une matière élastomère.In the case in particular of the examples of FIGS. 15, 17 and 18, the deformability of the first portion 12 may be obtained thanks to the presence of the openings 25, slots 27 or the bellows 30, and the first portion 12 may have sufficient deformability without the need to make it in an elastomeric material, the first portion 12 can be made, if necessary, in the same material as the rest of the rod. However, it is preferable, to benefit from further deformability, to make the first portion 12 at least partially in an elastomeric material.

L'invention trouve une application non seulement dans le domaine de l'application de vernis à ongles mais plus généralement dans le domaine du maquillage et par exemple pour l'application d'un produit sur les paupières, notamment un eye-liner.The invention finds application not only in the field of the application of nail polish but more generally in the field of makeup and for example for the application of a product on the eyelids, including an eyeliner.

Ce produit peut être contenu par exemple dans un récipient pourvu d'un organe d'essorage 33 comme illustré aux figures 19 et 33, lequel permet d'essorer l'organe d'application à sa sortie du récipient.This product may be contained for example in a container provided with a wiper member 33 as illustrated in FIGS. 19 and 33, which makes it possible to wring the applicator member out of the container.

L'organe d'essorage 33 peut être formé d'une mousse percée, comme illustré sur la figure 19, ou par un manchon en élastomère, comme illustré sur la figure 33.The wiper member 33 may be formed of a pierced foam, as illustrated in FIG. 19, or by an elastomer sleeve, as illustrated in FIG. 33.

L'organe d'application peut être constitué, dans le cas d'un eye-liner, par un pinceau comme illustré à la figure 20 ou par tout autre organe d'application, par exemple une pointe 34 en feutre, en mousse ou en d'autres matériaux, par exemple une matière plastique pleine, éventuellement élastomère. L'organe d'application peut comporter une pointe floquée 35, comme on le voit sur la figure 21.The applicator member may consist, in the case of an eyeliner, by a brush as illustrated in FIG. 20 or by any other applicator member, for example a point 34 made of felt, foam or other materials, for example a solid plastic material, optionally elastomeric. The applicator member may comprise a flocked tip 35, as can be seen in FIG.

L'applicateur peut être réalisé différemment encore et notamment la tige 6 peut être réalisée d'un seul tenant avec la capsule de fermeture 5, comme illustré à la figure 22.The applicator may be made differently still and in particular the rod 6 may be made in one piece with the closure cap 5, as shown in FIG. 22.

Lorsque l'organe d'application comporte un faisceau 10 de poils 11, ces derniers peuvent présenter diverses sections transversales, par exemple l'une de celles illustrées aux figures 24 à 29.When the applicator member comprises a bundle 10 of bristles 11, the latter may have various cross sections, for example one of those illustrated in FIGS. 24 to 29.

Les poils 11 peuvent notamment être pleins comme illustré sur la figure 23, creux comme on le voit sur la figure 24, de section polygonale comme illustré sur les figures 25 à 27, notamment carrée, triangulaire ou rectangulaire, ou ovale comme représenté sur la figure 28, et comporter éventuellement au moins une rainure capillaire 36, comme représenté sur la figure 29.The bristles 11 may especially be solid as shown in FIG. 23, hollow as can be seen in FIG. 24, of polygonal section as illustrated in FIGS. 25 to 27, in particular square, triangular or rectangular, or oval as represented in FIG. 28, and possibly comprise at least one capillary groove 36, as shown in FIG. 29.

Les poils peuvent être réalisés dans des matières naturelles ou synthétiques. On peut utiliser un mélange de poils ayant différentes formes et/ou réalisés dans différents matériaux.The bristles can be made of natural or synthetic materials. A mixture of bristles having different shapes and / or made in different materials can be used.

La tige peut comporter au moins une portion rigide.The rod may comprise at least one rigid portion.

Dans toute la description, y compris les revendications, l'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.Throughout the description, including the claims, the phrase "having one" should be understood as being synonymous with "having at least one", unless the opposite is specified.
