Description

La présente invention concerne les applicateurs pour appliquer un produit, notamment cosmétique, et les dispositifs de conditionnement et d'application comportant de tels applicateurs.The present invention relates to applicators for applying a product, in particular a cosmetic product, and packaging and application devices comprising such applicators.

L'invention concerne plus particulièrement les applicateurs pour appliquer un produit sur les fibres kératiniques, notamment les cils ou sourcils, par exemple du mascara.The invention relates more particularly to applicators for applying a product to keratinous fibers, in particular eyelashes or eyebrows, for example mascara.

Il est souhaitable que les applicateurs de mascara retiennent une quantité de produit suffisante pour qu'il ne soit pas nécessaire de les recharger trop souvent en cours d'application. Par ailleurs, ces applicateurs doivent permettre de saisir les cils, de les séparer, de les allonger et/ou de les recourber, selon le type de maquillage souhaité.It is desirable that the mascara applicators retain a sufficient amount of product so that it is not necessary to recharge them too often during application. Moreover, these applicators must make it possible to grasp the lashes, to separate them, to lengthen them and / or to bend them, according to the type of makeup desired.

La plupart des brosses ou peignes à mascara connus présentent des caractéristiques figées en ce qui concerne leur souplesse et la disposition dans l'espace des poils ou dents. De plus, l'utilisateur peut difficilement contrôler la quantité de produit dont se charge la brosse ou le peigne.Most known mascara brushes or combs have fixed characteristics with regard to their flexibility and the arrangement in the space of the bristles or teeth. In addition, the user can hardly control the amount of product that the brush or comb.

On connaît par les brevets US 3 998 235 et US 5 722 436 des applicateurs comportant des éléments d'application dont l'écartement peut être ajusté par l'utilisateur. Dans de tels applicateurs, l'écartement entre les éléments d'application est modifié par l'application d'une force de compression selon l'axe longitudinal de l'applicateur. On connaît encore par le brevet US 6 345 626 un applicateur comportant une pluralité de disques indépendants pouvant être comprimés axialement lorsque l'applicateur est retiré du récipient qui contient le produit à appliquer.Patent is known US 3,998,235,235 and US 5,722,436 applicators having application elements whose spacing can be adjusted by the user. In such applicators, the spacing between the application elements is modified by the application of a compressive force along the longitudinal axis of the applicator. We still know by the patent US 6,345,626 an applicator having a plurality of independent discs axially compressible when the applicator is removed from the container that contains the product to be applied.

On connaît par ailleurs par la demande de brevet FR 2 506 581 un applicateur comportant un manchon pourvu de quatre fentes. Le diamètre du manchon peut varier sous l'action d'une tige coulissant dans un manche creux de la brosse et dont le bout entraîne en déplacement une première extrémité du manchon, la deuxième extrémité du manchon étant immobilisée par le manche creux. Le manchon peut être placé au choix de l'utilisateur dans une position de diamètre minimum et dans une position de diamètre maximum. Du produit peut pénétrer à l'intérieur du manchon par les fentes, puis entre le manche creux et la tige coulissante. Le produit accumulé à l'intérieur du manchon échappe à l'essorage et peut entraîner un risque de salissures.
Le document US 4 446 880 A décrit un applicateur selon le préambule de la revendication 1.It is also known from the patent application FR 2,506,581 an applicator having a sleeve provided with four slots. The diameter of the sleeve may vary under the action of a sliding rod in a hollow handle of the brush and whose end drives in displacement a first end of the sleeve, the second end of the sleeve being immobilized by the hollow handle. The sleeve can be placed at the option of the user in a position of minimum diameter and in a position of maximum diameter. Product can penetrate inside the sleeve through the slots, then between the hollow handle and the sliding rod. The product accumulated inside the sleeve escapes spinning and can lead to a risk of soiling.
The document US 4,446,880 A discloses an applicator according to the preamble of claim 1.

Il existe un besoin pour pouvoir modifier préalablement à l'application et/ou en cours d'utilisation l'applicateur afm par exemple de l'adapter à la forme, au nombre, à la disposition, à l'épaisseur, à la souplesse et à la longueur des cils et des sourcils d'une personne, à la rhéologie du produit et/ou au type de maquillage souhaité.There is a need to be able to modify before the application and / or in use the applicator afm for example to adapt to the shape, the number, the disposition, the thickness, the flexibility and the length of the eyelashes and eyebrows of a person, the rheology of the product and / or the type of makeup desired.

La présente invention a pour objet un applicateur comportant :

  • un support d'axe longitudinal X, comportant :
    • une tige, et
    • une portion déformable ayant une première extrémité et une deuxième extrémité, la portion déformable pouvant se déformer radialement de manière élastique quand l'écartement entre les première et deuxième extrémités varie,
  • un organe d'application rapporté sur la portion déformable entre les première et deuxième extrémités et s'étendant continûment autour de celle-ci, et
  • un élément de réglage mobile au moins selon l'axe X relativement au support et agencé pour agir sur l'écartement entre les première et deuxième extrémités de la portion déformable.
The present invention relates to an applicator comprising:
  • a longitudinal axis support X, comprising:
    • a stem, and
    • a deformable portion having a first end and a second end, the deformable portion being elastically deformable radially when the spacing between the first and second ends varies,
  • an applicator member mounted on the deformable portion between the first and second ends and extending continuously therethrough, and
  • a movable adjusting element at least along the X axis relative to the support and arranged to act on the spacing between the first and second ends of the deformable portion.

Lorsque l'écartement entre les première et deuxième extrémités varie, la portion déformable en se déformant radialement peut provoquer la déformation de l'organe d'application. L'organe d'application est rapporté sur la portion déformable du support, ce qui peut permettre de fabriquer aisément plusieurs dispositifs ayant des supports identiques mais des organes d'applications différents.When the spacing between the first and second ends varies, the deformable portion deforming radially can cause the deformation of the applicator member. The applicator member is attached to the deformable portion of the support, which can make it easy to manufacture several devices having identical supports but different application members.

L'utilisateur peut, grâce à l'élément de réglage, modifier progressivement la forme et la courbure de l'organe d'application. Pour l'application de mascara par exemple, l'applicateur peut être réglé en fonction du maquillage que l'on souhaite réaliser. En réglant la section extérieure de l'organe d'application, on peut agir sur la quantité de produit dont se charge l'applicateur.The user can, thanks to the adjustment element, gradually change the shape and curvature of the application member. For the application of mascara, for example, the applicator can be adjusted according to the makeup that one wishes to achieve. By adjusting the outer section of the applicator member, it is possible to act on the amount of product that the applicator loads.

L'organe d'application peut aisément être réalisé si on le souhaite de manière à empêcher sensiblement le produit d'atteindre la portion déformable. L'organe d'application peut avantageusement être réalisé sans fentes longitudinales.The applicator member can easily be made if desired so as to substantially prevent the product from reaching the deformable portion. The applicator member can advantageously be made without longitudinal slots.

D'une manière générale, l'élément de réglage peut être mobile en rotation relativement au support. Le support et l'élément de réglage peuvent coopérer par vissage. L'élément de réglage peut notamment comporter un filetage apte à coopérer avec un filetage complémentaire ménagé sur le support. Le support peut comporter par exemple une surface intérieure filetée au niveau de la première extrémité ou en variante au niveau d'un organe de préhension du support.In general, the adjustment element can be rotatable relative to the support. The support and the adjustment element can cooperate by screwing. The adjusting element may in particular comprise a thread capable of cooperating with a complementary thread formed on the support. The support may comprise, for example, an internal threaded surface at the first end or alternatively at a support gripping member.

L'élément de réglage peut comporter un organe de commande qui fait saillie hors du support. L'organe de commande peut faire saillie hors du support au niveau de la deuxième extrémité ou en variante au niveau d'un organe de préhension du support.The adjusting element may comprise a control member which projects out of the support. The control member may project out of the support at the second end or alternatively at a support member of the support.

L'organe de commande peut être fixé de manière amovible ou non sur l'organe de préhension du support. L'organe de commande peut être configuré pour se visser sur l'organe de préhension, ou en variante être encliqueté sur l'organe de préhension ou encore être maintenu par friction.The control member may be fixed removably or not on the support member of the support. The control member may be configured to be screwed on the gripping member, or alternatively to be snapped onto the gripping member or to be held by friction.

L'organe de commande peut être mobile en rotation par rapport à l'organe de préhension et/ou mobile par rapport à l'organe de préhension parallèlement à un axe longitudinal de l'applicateur.The control member may be rotatable relative to the gripping member and / or movable relative to the gripping member parallel to a longitudinal axis of the applicator.

L'élément de réglage peut comporter une tige non entièrement symétrique de révolution, fixée dans un logement correspondant de l'organe de commande. La tige peut par exemple être de section transversale polygonale, carrée ou autre. L'entraînement en rotation de l'organe de commande peut provoquer ainsi la rotation de l'élément de réglage.The adjustment element may comprise a rod that is not entirely symmetrical in revolution and is fixed in a corresponding housing of the control member. The rod may for example be of polygonal cross section, square or other. The rotational drive of the control member can thus cause the rotation of the adjusting member.

La portion déformable du support peut comporter au moins une lamelle s'étendant longitudinalement, et de préférence une pluralité de lamelles, ces dernières étant par exemple équiréparties autour de l'axe longitudinal du support. Les lamelles peuvent par exemple être au nombre de quatre.The deformable portion of the support may comprise at least one longitudinally extending lamella, and preferably a plurality of lamellae, the latter being for example equidistributed around the longitudinal axis of the support. The slats can for example be four in number.

Les lamelles peuvent avoir au repos une forme de portion de cylindre. La portion déformable du support peut ainsi avoir au repos une section transversale extérieure sensiblement circulaire, mais on ne sort pas du cadre de la présente invention si la portion déformable du support présente une section transversale de forme différente, par exemple polygonale.The slats may have at rest a cylinder portion shape. The deformable portion of the support can thus have at rest a substantially circular outer cross section, but it is not beyond the scope of the present invention if the deformable portion of the support has a cross section of different shape, for example polygonal.

Les lamelles peuvent avoir au repos une forme bombée vers l'extérieur, favorisant leur déformation élastique radialement vers l'extérieur, ou en variante une forme bombée vers l'intérieur, favorisant leur déformation élastique radialement vers l'intérieur.The slats may have at rest an outwardly curved shape, promoting their elastic deformation radially outwardly, or alternatively an inwardly curved shape, favoring their elastic deformation radially inwards.

Le support peut comporter un épaulement sur lequel peut prendre appui l'organe d'application lorsque l'écartement entre les première et deuxième extrémités diminue.The support may comprise a shoulder on which the applicator member can bear when the spacing between the first and second ends decreases.

L'organe d'application peut être moulé d'une seule pièce en une matière élastiquement déformable. L'organe d'application peut être réalisé en élastomère ou dans tout autre matériau élastique permettant la compression et l'expansion radiale de l'organe d'application.The applicator member may be molded in one piece from an elastically deformable material. The applicator member may be made of elastomer or of any other elastic material allowing compression and radial expansion of the applicator member.

L'organe d'application peut par exemple comporter un corps creux cylindrique, par exemple en élastomère, comportant extérieurement des nervures circulaires ou polygonales, ou encore des poils injectés, venus de moulage avec le corps ou non.The applicator member may for example comprise a cylindrical hollow body, for example elastomer, having externally circular or polygonal ribs, or injected bristles, molded with the body or not.

La déformation de la portion déformable peut permettre d'agir sur l'écartement entre les extrémités des éléments d'application, de manière à régler la quantité de produit retenue sur l'organe d'application et distribuée.The deformation of the deformable portion may allow to act on the spacing between the ends of the application elements, so as to adjust the amount of product retained on the application member and distributed.

L'organe d'application peut présenter une surface enveloppe, lorsqu'il est non déformé, de section transversale choisie dans la liste non limitative suivante : polygonale, notamment carrée ou triangulaire, circulaire. L'organe d'application peut présenter une surface enveloppe passant par un extremum, notamment un maximum, entre ses extrémités axiales, lorsqu'il est non déformé.The applicator member may have an envelope surface, when undeformed, of cross-section chosen from the following nonlimiting list: polygonal, in particular square or triangular, circular. The applicator member may have an envelope surface passing through an extremum, in particular a maximum, between its axial ends, when it is not deformed.

Dans un exemple de réalisation, l'organe d'application comporte une pluralité d'éléments d'application engagés sur le support, par exemple une pluralité de disques.In an exemplary embodiment, the application member comprises a plurality of application elements engaged on the support, for example a plurality of disks.

La pluralité de disques peut comporter des disques de plus grand diamètre alternés avec des disques de plus petit diamètre. Les disques de plus grand diamètre peuvent comporter, lorsqu'ils sont en place sur le support, un diamètre croissant puis décroissant lorsqu'on se déplace le long de l'axe longitudinal du support.The plurality of disks may have larger diameter disks alternating with smaller diameter disks. The larger diameter discs may have, when in place on the support, a diameter increasing and decreasing when moving along the longitudinal axis of the support.

Le terme « disque » doit être compris au sens large. On entend par « disque » tout élément sensiblement aplati ayant une épaisseur inférieure à ses deux autres dimensions. Un disque n'est pas nécessairement de contour circulaire, ni complètement plat. Les disques de la pluralité de disques peuvent présenter des faces planes, tronconiques, concaves et/ou convexes, les faces opposées d'un disque étant identiques ou différentes.The term "disk" should be understood in a broad sense. "Disk" means any substantially flattened element having a thickness less than its two other dimensions. A disc is not necessarily circular or completely flat. The disks of the plurality of disks may have planar, frustoconical, concave and / or convex faces, the opposite faces of a disk being identical or different.

Au moins un élément d'application, par exemple un disque de la pluralité de disques précitée, peut comporter un moyen d'espacement élastiquement déformable s'appliquant contre un élément d'application adjacent et permettant le rapprochement de l'élément d'application avec l'élément d'application adjacent lorsque l'écartement entre la première et la deuxième extrémité diminue.At least one application element, for example a disk of the aforesaid plurality of disks, may comprise an elastically deformable spacing means applying against an adjacent applicator element and allowing the application element to be brought together with the adjacent applicator element when the spacing between the first and the second end decreases.

Le support et l'organe d'application peuvent être au moins partiellement réalisés dans le même matériau, notamment un matériau élastomère. L'un au moins du support et de l'organe d'application peut être réalisé au moins partiellement dans un matériau choisi parmi les résines thermoplastiques ou les métaux, comme l'acier inoxydable par exemple. Comme indiqué plus haut, le support peut comporter un organe de préhension à une extrémité de la tige. L'organe de préhension peut constituer un capuchon de fermeture d'un récipient contenant le produit à appliquer.The support and the applicator member may be at least partially made of the same material, in particular an elastomeric material. At least one of the support and the applicator member can be made at least partially in a material chosen from thermoplastic resins or metals, such as stainless steel for example. As indicated above, the support may comprise a gripping member at one end of the rod. The gripping member may constitute a closure cap of a container containing the product to be applied.

La plus grande dimension transversale de l'organe d'application peut varier d'un certain facteur lorsque la portion déformable passe d'un état de déformation nulle à un état de déformation maximale. Ce facteur ne doit pas dépasser la limite d'irréversibilité de déformation du matériau. Ce facteur peut être compris par exemple entre 1 et 1,25 pour un matériau thermoplastique. La distance maximale entre la première et la deuxième extrémité peut être comprise par exemple entre 0 et 35 mm. La distance minimale entre la première et la deuxième extrémité peut être comprise par exemple entre 0 et 26 mm.The largest transverse dimension of the applicator member may vary by a certain factor when the deformable portion changes from a state of zero deformation to a state of maximum deformation. This factor must not exceed the limit of irreversibility of deformation of the material. This factor can be for example between 1 and 1.25 for a thermoplastic material. The maximum distance between the first and the second end may be for example between 0 and 35 mm. The minimum distance between the first and the second end may be for example between 0 and 26 mm.

La portion déformable peut avantageusement être réalisée de façon monolithique avec la tige, par exemple par moulage.The deformable portion may advantageously be made monolithically with the rod, for example by molding.

On a représenté à la figure 1 un dispositif 1 de conditionnement et de distribution d'un produit P, cosmétique, de maquillage et/ou de soin, par exemple du mascara, comportant un récipient 2 contenant le produit P.We have shown figure 1 a device 1 for packaging and dispensing a product P, cosmetic, makeup and / or care, for example mascara, comprising a container 2 containing the product P.

Le récipient 2 comporte un col 4 dans lequel est fixé un organe d'essorage 5. Ce dernier comporte une collerette 6 qui vient en appui sur l'extrémité supérieure du col 4 et une lèvre d'essorage sensiblement conique 7 qui définit une plus petite section intérieure de l'organe d'essorage 5.The container 2 comprises a neck 4 in which is fixed a wiper member 5. The latter comprises a flange 6 which bears on the upper end of the neck 4 and a substantially conical wiper lip 7 which defines a smaller inner section of the wiper member 5.

Le dispositif 1 comporte en outre un applicateur 10 comportant un support 11 s'étendant selon un axe longitudinal X, un organe d'application 12 porté par le support 11 et un élément de réglage 13 mobile relativement au support 11.The device 1 further comprises an applicator 10 comprising a support 11 extending along a longitudinal axis X, an applicator member 12 carried by the support 11 and an adjusting element 13 movable relative to the support 11.

L'applicateur 10 est représenté plus en détail à la figure 2.The applicator 10 is shown in more detail at figure 2 .

Le support 11 comporte une tige 14 s'étendant selon l'axe longitudinal X et se raccordant supérieurement à un organe de préhension 3 servant également, dans l'exemple considéré, de capuchon de fermeture du récipient 2 et comportant une jupe filetée agencée pour se visser sur le col 4. La tige 14 se raccorde inférieurement à une portion déformable 17 ayant une première extrémité 15 adjacente à la tige 14 et une deuxième extrémité 16 opposée à la première. La portion déformable 17 est dans cet exemple de réalisation réalisée d'un seul tenant par moulage de matière avec la tige 14.The support 11 comprises a rod 14 extending along the longitudinal axis X and being connected superiorly to a gripping member 3 also serving, in the example in question, with a closing cap of the receptacle 2 and comprising a threaded skirt arranged for screw on the neck 4. The rod 14 is connected below a deformable portion 17 having a first end 15 adjacent to the rod 14 and a second end 16 opposite to the first. The deformable portion 17 is in this embodiment made in one piece by molding material with the rod 14.

La portion déformable 17 peut se déformer de manière élastique radialement, c'est-à-dire perpendiculairement à l'axe X, quand l'écartement entre la première extrémité 15 et la deuxième extrémité 16 diminue. A cet effet, la portion déformable 17 comporte des lamelles 20, qui sont dans l'exemple décrit au nombre de quatre, équi-réparties autour de l'axe X, comme on peut le voir sur la figure 3. Bien entendu, le nombre de lamelles pourrait être différent, étant par exemple compris entre 2 et 12, voire entre 3 et 10.The deformable portion 17 can deform elastically radially, that is to say perpendicularly to the X axis, when the spacing between the first end 15 and the second end 16 decreases. For this purpose, the deformable portion 17 comprises slats 20, which are in the example described in the number of four, equi-distributed around the axis X, as can be seen on the figure 3 . Of course, the number of slats could be different, being for example between 2 and 12 or even between 3 and 10.

L'organe d'application 12 est disposé entre la première extrémité 15 et la deuxième extrémité 16, autour de la portion déformable 17. Il comporte dans l'exemple un manchon en élastomère, portant extérieurement des éléments d'application se présentant sous la forme de nervures 22 annulaires, dont le diamètre extérieur augmente puis diminue quand on se déplace le long de l'axe longitudinal X du support 11 entre les extrémités 15 et 16.The applicator member 12 is disposed between the first end 15 and the second end 16, around the deformable portion 17. It comprises in the example a elastomeric sleeve, externally carrying application elements in the form of annular ribs 22, the outer diameter increases and then decreases when moving along the longitudinal axis X of the support 11 between the ends 15 and 16.

Dans l'exemple illustré, la tige 14 est creuse et l'élément de réglage 13 est libre en rotation à l'intérieur de celle-ci. Bien entendu, on ne sort pas du cadre de la présente invention si l'élément de réglage est mobile relativement au support 11 autrement qu'en rotation, notamment seulement en translation. Dans l'exemple considéré, l'élément de réglage 13 s'étend jusqu'à l'extrémité supérieure du dispositif et comporte à cette extrémité un organe de commande 25. Ce dernier coopère dans l'exemple illustré par vissage avec l'organe de préhension 3.In the illustrated example, the rod 14 is hollow and the adjustment element 13 is free to rotate inside thereof. Of course, it is not beyond the scope of the present invention if the adjustment element is movable relative to the support 11 other than in rotation, in particular only in translation. In the example considered, the adjustment element 13 extends to the upper end of the device and comprises at this end a control member 25. The latter cooperates in the example shown by screwing with the body of the device. gripping 3.

L'élément de réglage 13 comporte, à son extrémité inférieure, une tête 26 qui vient axialement en appui sur la deuxième extrémité 16 de la portion déformable 17.The adjusting element 13 comprises, at its lower end, a head 26 which bears axially on the second end 16 of the deformable portion 17.

Lorsque l'utilisateur dévisse l'organe de commande 25 relativement à l'organe de préhension 3, l'élément de réglage 13 est entraîné en rotation autour de l'axe X et se déplace vers le haut selon cet axe relativement au support 11.When the user unscrews the control member 25 relative to the gripping member 3, the adjusting element 13 is rotated about the axis X and moves upwards along this axis relative to the support 11.

La tête 26 en se déplaçant en direction de l'organe de préhension 3 provoque le rapprochement de la première extrémité 15 et de la deuxième extrémité 16, comme on peut le voir sur la figure 4, et une déformation des lamelles 20 radialement vers l'extérieur dans l'exemple considéré.The head 26 moving in the direction of the gripping member 3 causes the first end 15 and the second end 16 to come together, as can be seen in FIG. figure 4 and a deformation of the lamellae radially outwardly in the example under consideration.

Les lamelles 20 présentent au repos une forme de portion de cylindre par exemple, mais on ne sort pas du cadre de la présente invention si les lamelles sont au repos bombées vers l'extérieur, ce qui peut favoriser la déformation radialement vers l'extérieur de la portion déformable 17. Les lamelles 20 pourraient également avoir au repos une forme bombée vers l'intérieur, favorisant la déformation élastique radialement vers l'intérieur de la portion déformable 17.The slats 20 have at rest a cylinder portion shape for example, but it is not beyond the scope of the present invention if the slats are at rest bulging outwards, which can promote the radially outward deformation of the deformable portion 17. The strips 20 could also have at rest an inwardly curved shape, promoting the elastic deformation radially inwardly of the deformable portion 17.

On a illustré aux figures 3 à 5 la déformation de la portion déformable 17, sans faire apparaître l'organe d'application 12 pour plus de clarté, lorsque la première extrémité 15 et la deuxième extrémité 16 sont de plus en plus rapprochées.We have illustrated Figures 3 to 5 the deformation of the deformable portion 17, without the appearance of the applicator member 12 for clarity, when the first end 15 and the second end 16 are closer and closer.

La déformation des lamelles 20 entraîne celle de l'organe d'application 12, qui peut se déformer élastiquement vers l'extérieur, l'organe d'application 12 étant maintenu axialement dans l'exemple considéré entre la tête 26 de l'organe de réglage 13 et un épaulement 27 du support 11, formé au niveau de la première extrémité 15.The deformation of the slats 20 causes that of the applicator member 12, which can elastically deform outwards, the application member 12 being maintained axially in the example considered between the head 26 of the adjusting member 13 and a shoulder 27 of the support 11, formed at the first end 15.

Le dispositif 1 peut s'utiliser de la manière suivante.The device 1 can be used in the following manner.

L'applicateur 10 étant présent dans le récipient 2, l'utilisateur peut faire tourner l'organe de commande 25 de manière à agir sur la distance entre la première extrémité 15 et la deuxième extrémité 16 et amener l'organe d'application 12 à prendre la forme souhaitée.Since the applicator 10 is present in the container 2, the user can turn the control member 25 so as to act on the distance between the first end 15 and the second end 16 and cause the applicator member 12 to take the desired shape.

Il dévisse ensuite l'organe de préhension 3 et retire l'applicateur 10. Au passage de l'organe d'essorage 5, notamment de sa plus petite section intérieure, l'organe d'application 12 est essoré de manière plus ou moins approfondie, selon son diamètre extérieur, lequel dépend du réglage précédemment effectué.It then unscrews the gripping member 3 and removes the applicator 10. At the passage of the wiper member 5, in particular of its smaller internal section, the applicator member 12 is dewatered in a more or less thorough manner. , depending on its outside diameter, which depends on the setting previously made.

Dans le cas où la première extrémité 15 et la deuxième extrémité 16 sont rapprochées au maximum, l'expansion radiale de l'organe d'application 12 est maximale et l'essorage est relativement poussé. L'allongement, le peignage et la séparation des cils peuvent être améliorés étant donné que les nervures 22 sont plus proches et peuvent par exemple permettre de mieux saisir les cils.In the case where the first end 15 and the second end 16 are brought closer together, the radial expansion of the applicator member 12 is maximum and the spin is relatively high. Elongation, combing and separation of the eyelashes can be improved since the ribs 22 are closer and can for example make it possible to better grasp the eyelashes.

A l'inverse, dans le cas où la première extrémité 15 et la deuxième extrémité 16 sont éloignées au maximum, l'expansion radiale de l'organe d'application 12 est minimale et l'essorage est minimal, la quantité de produit prélevée étant alors plus grande.Conversely, in the case where the first end 15 and the second end 16 are at most distant, the radial expansion of the applicator member 12 is minimal and the spin is minimal, the quantity of product sampled being then bigger.

L'organe d'application 12 peut être galbé à volonté par simple action sur l'organe de commande 25, ce qui permet de l'adapter à la courbure des cils ou sourcils et au type de maquillage souhaité.The applicator member 12 may be curved at will by simple action on the control member 25, which makes it possible to adapt it to the curvature of the eyelashes or eyebrows and to the type of makeup desired.

Bien entendu, toutes les positions intermédiaires entre les deux positions extrêmes qui viennent d'être décrites sont possibles, le réglage pouvant se faire de manière continue et progressive dans l'exemple considéré.Of course, all the intermediate positions between the two extreme positions that have just been described are possible, the setting being continuous and progressive in the example considered.

L'organe de préhension 3 et/ou l'organe de commande 25 peuvent, le cas échéant, comporter au moins une indication facilitant un réglage prédéterminé de l'écartement entre la première extrémité 15 et la deuxième extrémité 16. Ils peuvent par exemple comporter au moins un repère correspondant à un degré de rapprochement prédéfmi entre la première extrémité 15 et la deuxième extrémité 16. Ce ou ces repères peuvent par exemple se présenter sous la forme d'icônes représentant la forme de l'organe d'application 12 lorsque la première extrémité 15 et la deuxième extrémité 16 sont dans la position correspondante.The gripping member 3 and / or the control member 25 may, where appropriate, comprise at least one indication facilitating a predetermined adjustment of the spacing between the first end 15 and the second end 16. They may for example comprise at least one mark corresponding to a predefined degree of approximation between the first end 15 and the second end 16. This or these markers may for example be in the form of icons representing the shape of the organ 12 when the first end 15 and the second end 16 are in the corresponding position.

L'organe d'application 12 peut être réalisé dans une résine thermoplastique, par exemple dans un matériau élastomère. Le support 11 peut être réalisé dans le même matériau que l'organe d'application 12 ou, en variante, dans un autre matériau.The applicator member 12 may be made of a thermoplastic resin, for example an elastomeric material. The support 11 may be made of the same material as the applicator member 12 or, alternatively, in another material.

L'élément de réglage 13 peut être réalisé de manière monolithique ou non, par exemple au moins partiellement dans une matière thermoplastique ou dans un métal.The adjusting element 13 may be made monolithically or not, for example at least partially in a thermoplastic material or in a metal.

Bien entendu, on ne sort pas du cadre de la présente invention lorsque l'élément de réglage 13 est réalisé différemment.Of course, it is not beyond the scope of the present invention when the adjustment element 13 is made differently.

A titre d'exemple, on a représenté à la figure 6 un élément de réglage 13 comportant une tige 29 fixée supérieurement à un organe de commande 25 mobile en rotation et axialement par rapport à l'organe de préhension 3. La tige 29 de l'élément de réglage 13 coopère avec le support 11 par vissage, et comporte à cet effet un filetage 28 engagé dans un filetage complémentaire ménagé sur une surface intérieure du support, par exemple dans l'organe de préhension 3. Bien entendu, le filetage pourrait se situer ailleurs, par exemple au niveau de la première extrémité 15, ou à un autre endroit encore. La tige 29 est de préférence non entièrement symétrique de révolution, ayant par exemple au moins une section carré, comme on l'a illustré à la figure 7, là où elle est engagée dans un logement correspondant 30 de l'organe de commande 25, de sorte que lorsque l'organe de commande 25 est entraîné en rotation par rapport à l'organe de préhension 3, il entraîne avec lui la tige 29 qui se déplace alors axialement par rapport au support 11 grâce au filetage 27, et la deuxième extrémité 16 se rapproche de la première extrémité 15.For example, there is shown in the figure 6 an adjusting element 13 comprising a rod 29 fixed above a control member 25 that is rotatable and axially with respect to the gripping member 3. The rod 29 of the adjusting element 13 cooperates with the support 11 by screwing, and comprises for this purpose a thread 28 engaged in a complementary thread formed on an inner surface of the support, for example in the gripping member 3. Of course, the threading could be located elsewhere, for example at the first end 15 , or somewhere else. The rod 29 is preferably not entirely symmetrical with revolution, having for example at least one square section, as illustrated in FIG. figure 7 where it is engaged in a corresponding housing 30 of the control member 25, so that when the control member 25 is rotated relative to the gripping member 3, it carries with it the rod 29 which then moves axially relative to the support 11 thanks to the thread 27, and the second end 16 approaches the first end 15.

En variante, l'organe de commande 25 peut être fixé par encliquetage sur l'organe de préhension 3, comme on l'a illustré à titre d'exemple à la figure 8, de manière à être fixe axialement mais mobile en rotation relativement à l'organe de préhension 3. Dans cet exemple de réalisation, la tige 29 peut se déplacer axialement à l'intérieur du logement 30 de l'organe de commande 25.Alternatively, the control member 25 may be snap-fastened to the gripping member 3, as illustrated by way of example in FIG. figure 8 , so as to be fixed axially but rotatable relative to the gripping member 3. In this embodiment, the rod 29 can move axially inside the housing 30 of the control member 25.

Lorsque l'organe de commande 25 est entraîné en rotation par rapport au capuchon de fermeture 3, il entraîne avec lui la tige 29 de section carrée, et le filetage 27 provoque le déplacement vers le haut de l'élément de réglage 13 dans le logement 30.When the control member 25 is rotated relative to the closure cap 3, it carries with it the rod 29 of square section, and the thread 27 causes the upward movement of the adjusting member 13 in the housing 30.

Dans les exemples qui viennent d'être décrits, l'organe de commande 25 fait saillie hors du support 11 au niveau de l'organe de préhension 3 de l'applicateur.In the examples which have just been described, the control member 25 protrudes out of the support 11 at the gripping member 3 of the applicator.

On ne sort pas du cadre de la présente invention lorsque l'organe de commande 25 fait saillie hors du support 11 au niveau de la deuxième extrémité 16, comme on l'a représenté à titre d'exemple sur les figures 9 et 10.It is not beyond the scope of the present invention when the control member 25 protrudes out of the support 11 at the second end 16, as shown by way of example on the Figures 9 and 10 .

Dans l'exemple des figures 9 et 10, le support 11 et l'élément de réglage 13 coopèrent par vissage, le filetage 27 étant situé au niveau de la première extrémité 15.In the example of Figures 9 and 10 , the support 11 and the adjusting element 13 cooperate by screwing, the thread 27 being located at the first end 15.

L'élément de réglage 13 peut être beaucoup plus court que dans les exemples qui ont été décrits précédemment et ne pas s'étendre jusqu'à l'organe de préhension 3.The adjustment element 13 may be much shorter than in the examples which have been described above and not extend to the gripping member 3.

Lorsque l'organe de commande 25 est entraîné en rotation par rapport au support 11 et que l'organe de commande 25 vient en appui axialement contre la deuxième extrémité 16, comme illustré sur la figure 10, l'écartement entre la première extrémité 15 et la deuxième extrémité 16 peut être modifié.When the control member 25 is rotated relative to the support 11 and the control member 25 bears axially against the second end 16, as shown in FIG. figure 10 , the spacing between the first end 15 and the second end 16 may be modified.

L'organe d'application 12 peut être réalisé de diverses manières.The applicator member 12 can be made in a variety of ways.

A titre d'exemple, on a représenté à la figure 11 un organe d'application 12 comportant un corps creux 35 cylindrique configuré pour se monter sur la portion déformable 17 et des éléments d'application se présentant sous la forme de poils 36 venus de moulage par injection avec le corps 35.For example, there is shown in the figure 11 an applicator member 12 comprising a cylindrical hollow body 35 configured to mount on the deformable portion 17 and application members in the form of bristles 36 formed by injection molding with the body 35.

On a représenté sur la figure 11 une seule rangée de poils 36, pour plus de clarté, mais l'organe d'application 12 peut comporter plusieurs rangées de poils 36, réparties uniformément ou non, ces rangées pouvant s'étendre parallèlement ou perpendiculairement à l'axe X, ou encore des poils 36 disposés en quinconce.We have shown on the figure 11 a single row of bristles 36, for the sake of clarity, but the applicator member 12 may comprise several rows of bristles 36, evenly distributed or not, these rows being able to extend parallel or perpendicular to the X axis, or bristles 36 arranged in staggered rows.

L'organe d'application 12 peut présenter une surface enveloppe de section transversale autre que circulaire, par exemple polygonale, notamment triangulaire, comme illustré à la figure 12, ou carrée, comme illustré à la figure 13.The applicator member 12 may have an envelope surface of cross-section other than circular, for example polygonal, in particular triangular, as illustrated in FIG. figure 12 , or square, as shown in figure 13 .

Dans tous les exemples qui viennent d'être décrits, l'organe d'application 12 est réalisé d'un seul tenant par moulage, mais on ne sort pas du cadre de la présente invention lorsque l'organe d'application est formé par un assemblage d'éléments d'application indépendants, par exemple par empilage d'éléments d'application se présentant sous la forme de disques.In all the examples which have just been described, the applicator member 12 is made in one piece by molding, but it is not beyond the scope of the present invention when the applicator member is formed by a assembly of independent application elements, for example by stacking application elements in the form of disks.

A titre d'exemple, on a représenté à la figure 14 un applicateur 10 comportant une pluralité de disques 40, indépendants les uns des autres. Pour plus de clarté, on a représenté à la figure 14 quatre disques seulement, mais bien entendu l'applicateur 10 peut comporter un plus grand nombre de disques répartis tout le long de la portion déformable 17.For example, there is shown in the figure 14 an applicator 10 having a plurality of disks 40, independent of each other. For the sake of clarity, it has been shown figure 14 only four discs, but of course the applicator 10 can have a larger number of disks distributed throughout the deformable portion 17.

Les disques 40 sont par exemple maintenus entre la tête 26 de l'élément de réglage 13 et l'épaulement 27 du support 11.The disks 40 are for example held between the head 26 of the adjusting element 13 and the shoulder 27 of the support 11.

Les disques 40 comportent un ajour central 41 permettant leur montage sur la portion déformable 17 du support 11 et un moyen d'espacement 42, élastiquement déformable, permettant d'espacer le disque d'un disque adjacent tout en permettant le rapprochement des disques lorsque l'écartement entre la première extrémité 15 et la deuxième extrémité 16 diminue, comme illustré sur la figure 15.The disks 40 comprise a central aperture 41 enabling them to be mounted on the deformable portion 17 of the support 11 and an elastically deformable spacing means 42 making it possible to space the disk of an adjacent disk while allowing the disks to be brought together when the distance between the first end 15 and the second end 16 decreases, as illustrated in FIG. figure 15 .

Le moyen d'espacement 42 est constitué par exemple, comme illustré sur la figure 14, par une lèvre annulaire venue de moulage avec le disque, s'étendant au repos sensiblement parallèlement à l'axe X et pouvant fléchir lors du rapprochement des disques.The spacing means 42 is constituted for example, as illustrated in FIG. figure 14 , by an annular lip formed integrally with the disk, extending at rest substantially parallel to the axis X and being able to bend when the disks are brought together.

Le disque 40 peut présenter une face concave et une face convexe, comme illustré sur la figure 14, la lèvre 42 se raccordant par exemple à la face convexe, ou présenter une face plane et une face convexe, comme illustré à la figure 16.The disk 40 may have a concave face and a convex face, as shown in FIG. figure 14 , the lip 42 being connected for example to the convex face, or having a flat face and a convex face, as illustrated in FIG. figure 16 .

Sur la figure 17, on a représenté un disque avec des moyens d'espacement constitués de deux lèvres 42 concentriques.On the figure 17 , there is shown a disk with spacing means consisting of two concentric lips 42.

Le disque 40 représenté à la figure 18 présente deux faces opposées sensiblement tronconiques, le disque s'amincissant en direction de sa périphérie. Le disque 40 représenté à la figure 18 peut augmenter de diamètre sous la pression des autres disques lorsque la première portion 15 et la deuxième portion 16 se rapprochent.The disc 40 shown at figure 18 has two opposite substantially frustoconical faces, the disc tapering toward its periphery. The disc 40 shown at figure 18 may increase in diameter under the pressure of the other discs when the first portion 15 and the second portion 16 come closer together.

Les disques illustrés sont de contour circulaire, mais ils pourraient avoir en variante un contour polygonal.The disks illustrated are circular in outline, but they could alternatively have a polygonal outline.

Dans ce qui vient d'être décrit, tous les disques d'un applicateur sont identiques, mais on ne sort pas du cadre de la présente invention si un applicateur 10 comporte des disques différents, par exemple des disques 45 de plus grand diamètre alternés avec des disques 46 de plus petit diamètre, comme illustré à la figure 19.In what has just been described, all the disks of an applicator are identical, but it is not beyond the scope of the present invention if an applicator 10 comprises different disks, for example disks 45 of larger diameter alternated with discs 46 of smaller diameter, as illustrated in FIG. figure 19 .

Les disques 45 de plus grand diamètre présentent par exemple, lorsqu'ils sont en place sur le support 11, un diamètre croissant lorsqu'on se déplace le long de l'axe longitudinal du support en direction de l'organe de préhension 3, ou en variante, lorsqu'on se déplace en direction de la deuxième extrémité 16.The discs 45 of larger diameter have for example, when in place on the support 11, an increasing diameter when moving along the longitudinal axis of the support towards the gripping member 3, or alternatively, when moving towards the second end 16.

Les disques 46 de plus petit diamètre sont dans l'exemple décrit tous identiques, et sont d'une forme qui facilite leur déformation radiale lorsque les première 15 et deuxième 16 extrémités se rapprochent, par exemple avec une gorge annulaire à leur périphérie. Une telle configuration peut permettre en outre d'accroître encore la quantité de produit retenue par l'applicateur.The discs 46 of smaller diameter are in the example described all identical, and are of a shape that facilitates their radial deformation when the first 15 and second 16 ends approach, for example with an annular groove at their periphery. Such a configuration can also further increase the amount of product retained by the applicator.

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.
