Description

La présente invention concerne les dispositifs utilisés en cosmétique pour le maquillage des cils et des sourcils, et plus particulièrement mais non exclusivement ceux comportant une source vibrante permettant de soumettre un organe d'application à des vibrations lors de l'utilisation.The present invention relates to devices used in cosmetics for the makeup of eyelashes and eyebrows, and more particularly but not exclusively those comprising a vibrating source for subjecting an application member to vibrations during use.

De tels applicateurs sont déjà connus, notamment des publications WO 2006/09343 et FR 2 904 923 de la demanderesse.Such applicators are already known, including publications WO 2006/09343 and FR 2,904,923 of the plaintiff.

EP 1 935 279 divulgue un applicateur dans lequel l'organe d'application comporte une âme et une enveloppe externe libre relativement à l'âme. EP 1 935 279 discloses an applicator in which the applicator member comprises a core and a free outer envelope relative to the core.

On connaît par ailleurs, d'applicateurs anciens, des organes d'application métalliques. Les organes d'application métalliques ont été abandonnés, dans la pratique, au profit d'applicateurs comportant des brosses à âme torsadée ou des brosses ou peignes réalisés par injection de matière thermoplastique, jugés moins agressifs.Also known, old applicators, metal application members. The metal application members have been abandoned, in practice, in favor of applicators comprising twisted core brushes or brushes or combs made by injection of thermoplastic material, considered less aggressive.

L'invention vise à perfectionner encore les applicateurs pour l'application d'un produit sur les cils et/ou sourcils.The invention aims to further improve the applicators for the application of a product on the eyelashes and / or eyebrows.

L'invention a pour objet, selon un premier de ses aspects, un applicateur comportant :

  • un organe d'application au moins partiellement en un matériau inorganique, comportant une âme différente d'une âme torsadée et des éléments d'application en saillie portés par l'âme, notamment autres qu'un ressort hélicoïdal,
  • une tige supportant l'organe d'application et comportant une portion rigide et une portion flexible, notamment en matière synthétique, s'étendant entre l'organe d'application et la portion rigide.
The object of the invention is, according to a first aspect, an applicator comprising:
  • an applicator member at least partially made of an inorganic material, comprising a core that is different from a twisted core and protruding application elements carried by the core, in particular other than a helical spring,
  • a rod supporting the applicator member and having a rigid portion and a flexible portion, in particular of synthetic material, extending between the applicator member and the rigid portion.

Par "âme torsadée" il faut comprendre une âme formée par deux branches d'un fil métallique, torsadées entre elles pour retenir des poils entre les spires de l'âme. Les brosses à mascara conventionnelles comportent des âmes torsadées.By "twisted soul" it is necessary to understand a soul formed by two branches of a wire, twisted together to retain hair between the turns of the soul. Conventional mascara brushes have twisted cores.

Par "matériau inorganique" il faut comprendre un matériau autre qu'un polymère à chaîne carbonée ou siliconée, notamment autre qu'une matière thermoplastique. Il peut s'agir d'un matériau à température de fusion relativement élevée, par exemple supérieure à 400°C, conducteur de l'électricité ou non et qui peut être de densité relativement élevée, par exemple supérieure à 1, 1,4, 1,5 ou 2. Il peut s'agir d'un matériau à l'état massique et non sous forme de charge dispersée.By "inorganic material" it is necessary to understand a material other than a polymer with a carbon or silicone chain, in particular other than a thermoplastic material. It may be a material with a relatively high melting temperature, for example greater than 400 ° C., which is electrically conductive or not and which may be of relatively high density, for example greater than 1, 1.4, 1.5 or 2. It may be a material in the mass state and not in the form of dispersed filler.

Le matériau inorganique peut être choisi parmi les métaux, les verres, minéraux, les céramiques, notamment à base d'alumine, de terres rares ou de ferrites.The inorganic material may be chosen from metals, glasses, minerals, ceramics, in particular based on alumina, rare earths or ferrites.

L'organe d'application peut être supporté directement par la portion flexible dans certains exemples de réalisation.The applicator member may be supported directly by the flexible portion in certain embodiments.

L'organe d'application peut comporter des éléments d'application formés par les crêtes d'une vis à filet hélicoïdal, notamment une vis métallique.The applicator member may comprise application elements formed by the ridges of a helical thread screw, in particular a metal screw.

La présence de la portion flexible confère plus de souplesse à l'applicateur et permet de compenser en partie le caractère rigide de l'organe d'application, dû à l'emploi dudit matériau inorganique, par exemple du métal.The presence of the flexible portion gives the applicator more flexibility and makes it possible to partially compensate for the rigid nature of the applicator member, due to the use of said inorganic material, for example metal.

La "matière synthétique" peut être une matière thermoplastique.The "synthetic material" can be a thermoplastic material.

L'invention permet d'utiliser de nouveaux organes d'application en des matériaux durs tels que du métal, du verre, une céramique par exemple, sans pour autant que leur utilisation soit perçue comme agressive par l'utilisateur, comparativement à la souplesse présentée par les brosses à âme torsadée notamment.The invention makes it possible to use new application members in hard materials such as metal, glass, a ceramic for example, without their use being perceived as aggressive by the user, compared to the flexibility presented. by brushes with twisted core in particular.

L'âme peut être inorganique ou non et les éléments d'application en matériau inorganique ou non, par exemple non métallique ou métallique. Par exemple, l'organe d'application peut être entièrement métallique, en verre ou en céramique. En variante, l'organe d'application comporte des parties en matériau inorganique, notamment métallique et d'autres en matériau inorganique, notamment non métalliques. Des éléments d'application non métalliques, par exemple en matière thermoplastique, peuvent être rapportés et/ou moulés sur une armature métallique ou en tout autre matériau inorganique de l'organe d'application, laquelle peut définir le cas échéant des éléments d'application, notamment métalliques.The core may be inorganic or non-inorganic and the application elements made of inorganic or non-inorganic material, for example non-metallic or metallic. For example, the applicator member may be entirely metallic, glass or ceramic. As a variant, the applicator member comprises parts made of inorganic material, in particular metal, and others made of inorganic material, in particular non-metallic materials. Non-metallic application elements, for example made of thermoplastic material, can be attached and / or molded on a metal reinforcement or in any other inorganic material of the applicator member, which can define, if necessary, application elements. , especially metal.

L'âme peut ne pas comporter deux éléments libres en déplacement l'un par rapport à l'autre.The soul may not have two free elements moving relative to each other.

L'organe d'application peut être réalisé au moins partiellement par moulage de métal, usinage, décolletage, fraisage, perçage, usinage laser ou électroérosion, entre autres techniques de fabrication, selon le matériau utilisé.The application member can be made at least partially by metal molding, machining, bar turning, milling, drilling, laser machining or electroerosion, among other manufacturing techniques, depending on the material used.

On peut tout particulièrement utiliser comme métal un métal brut pour réaliser l'organe d'application, par exemple de l'aluminium ou de l'alliage Zamak®.It is particularly possible to use as a metal a raw metal to make the application member, for example aluminum or Zamak ® alloy.

L'invention a encore pour objet, selon un autre de ses aspects, un dispositif pour appliquer un produit cosmétique ou de soin, comportant une source vibrante, une tige et un organe d'application porté par la tige et soumis aux vibrations de la source vibrante, cet organe d'application comportant une âme autre qu'une âme torsadée et étant au moins partiellement métallique, notamment comportant des éléments d'application autres qu'un ressort hélicoïdal.Another subject of the invention, according to another of its aspects, is a device for applying a cosmetic or care product, comprising a vibrating source, a stem and an applicator member carried by the rod and subjected to the vibrations of the vibrating source, this applicator member comprising a core other than a twisted core and being at least partially metallic, in particular comprising application elements other than a helical spring.

La présence additionnelle d'une tige ayant une portion flexible telle que définie ci-dessus, peut faciliter le réglage des vibrations à la conception du dispositif, notamment en ce qui concerne la transmission des vibrations de la tige à l'organe d'application.The additional presence of a rod having a flexible portion as defined above, may facilitate the adjustment of the vibrations to the design of the device, particularly as regards the transmission of vibrations from the rod to the applicator member.

Qu'il y ait présence d'une source vibrante ou non, et présence d'une tige à portion flexible ou non, l'élément d'application en saillie peut se présenter sous la forme d'une nervure s'étendant autour de l'âme, qui peut être interrompue par une ou plusieurs encoches. Cette nervure peut être en forme de disque ou de filet ou portion de filet hélicoïdal.Whether there is a vibrating source or not, and presence of a rod with flexible portion or not, the projecting element may be in the form of a rib extending around the soul, which can be interrupted by one or more notches. This rib can be in the form of disc or net or portion of helical thread.

La masse de l'organe d'application peut, grâce à la présence du matériau inorganique, notamment du métal, être plus élevée et l'amplitude des vibrations à l'extrémité distale de l'organe d'application peut être augmentée si cela est recherché, notamment par un phénomène de résonance.The mass of the applicator member may, due to the presence of the inorganic material, in particular the metal, be higher and the amplitude of the vibrations at the distal end of the applicator member may be increased if this is sought, especially by a phenomenon of resonance.

De nouvelles possibilités de maquillage sont offertes par l'utilisation d'un organe d'application en matériau inorganique, donc rigide, ayant un comportement mécanique différent à l'essorage et à l'application, notamment lorsque soumis à des vibrations, de celui des organes d'application en matière thermoplastique injectée ou des brosses à âme torsadée.New makeup possibilities are offered by the use of an application member made of inorganic material, therefore rigid, having a different mechanical behavior to the spin and application, especially when subjected to vibrations, that of application members of injected thermoplastic material or brushes with twisted core.

L'invention permet de plus de réaliser des traitements de surface impossibles à réaliser avec des matières thermoplastiques, par exemple pour conférer plus de glissant ou plus d'accroche, et une grande diversité de formes est possible, en fonction notamment des techniques de fabrication utilisées. Ainsi, le décolletage ou l'attaque laser peuvent servir à donner à l'organe d'application la forme voulue, entre autres techniques de fabrication, comme mentionné ci-dessus.The invention also makes it possible to perform surface treatments impossible to achieve with thermoplastic materials, for example to provide more slippery or more grip, and a wide variety of shapes is possible, depending in particular on the manufacturing techniques used. . Thus, machining or laser etching can be used to give the application member the desired shape, among other manufacturing techniques, as mentioned above.

L'invention offre également la possibilité de bénéficier, si cela est souhaité, d'interactions physicochimiques nouvelles entre le produit à appliquer et l'organe d'application, par exemple pour profiter d'une action biocide éventuelle d'un métal utilisé pour réaliser au moins partiellement l'organe d'application, d'une aimantation éventuelle, notamment lors de l'utilisation de ferrites ou de terres rares, ou d'une capacité à libérer des ions, par exemple fluor ou calcium, entre autres effets.The invention also offers the possibility of benefiting, if desired, from new physicochemical interactions between the product to be applied and the application member, for example to take advantage of any biocidal action of a metal used to produce at least partially the application member, of a possible magnetization, especially when using ferrites or rare earths, or an ability to release ions, for example fluorine or calcium, among other effects.

L'invention offre encore de nouvelles possibilités esthétiques, par exemple en réalisant des organes d'application recouverts d'un métal noble, par exemple de l'or, de l'argent ou du tungstène. On peut encore revêtir le matériau inorganique d'un matériau synthétique, par exemple du PTFE, pour améliorer le glissant notamment, ou modifier la tension de surface.The invention still offers new aesthetic possibilities, for example by producing application members coated with a noble metal, for example gold, silver or tungsten. The inorganic material can also be coated with a synthetic material, for example PTFE, to improve the slipperiness in particular, or to modify the surface tension.

L'organe d'application peut encore être floqué au moins partiellement, notamment sur une partie en matériau inorganique, par exemple métallique.The applicator member may also be flocked at least partially, in particular on a portion of inorganic material, for example metal.

L'organe d'application peut porter au moins un poil ou une touffe de poils, retenu sur une partie en matériau inorganique, notamment métallique, de l'organe d'application, par collage, agrafage ou déformation de la partie en matériau inorganique, notamment métallique par matriçage, lorsque le matériau inorganique présente une ductilité suffisante. Lorsqu'au moins un élément d'application est retenu par agrafage, ce dernier peut se faire après perçage du matériau destiné à recevoir l'agrafe, notamment quand celui-ci est métallique. Le ou les éléments d'application peuvent être plaqués contre une surface de l'âme avant l'agrafage, ce qui peut améliorer la tenue de l'agrafe.The applicator member may carry at least one hair or a tuft of bristles, retained on a portion of inorganic material, in particular metal, of the applicator member, by gluing, stapling or deformation of the portion of inorganic material, particularly metal by stamping, when the inorganic material has sufficient ductility. When at least one application element is retained by stapling, it can be done after drilling the material for receiving the staple, especially when it is metallic. The application member (s) may be pressed against a surface of the core prior to stapling, which may enhance staple holding.

L'organe d'application peut comporter un logement traversant ou borgne, réalisé dans une partie en matériau inorganique, notamment métallique, et dans lequel est reçu au moins un élément d'application non métallique, notamment en matériau thermoplastique, qui peut être encliqueté ou monté à force dans le logement. Ce dernier peut se présenter, par exemple, sous la forme d'une fente, par exemple allongée selon l'axe longitudinal de l'organe d'application. Plusieurs éléments d'application peuvent être moulés d'une seule pièce en matière thermoplastique et rapportés dans une telle fente.The applicator member may comprise a through or blind housing, made in a portion of inorganic material, in particular a metal material, and in which at least one non-metallic application element, in particular made of thermoplastic material, which can be latched or forcibly mounted in the dwelling. The latter may be, for example, in the form of a slot, for example elongate along the longitudinal axis of the applicator member. Several application elements can be molded in one piece of thermoplastic material and reported in such a slot.

L'organe d'application peut être réalisé de façon monobloc, en métal ou dans un autre matériau inorganique. En variante, l'organe d'application peut comporter des éléments d'application au moins partiellement métalliques ou autre matériau inorganique et d'autres non métalliques, notamment en matière thermoplastique.The applicator member may be made integrally, of metal or of another inorganic material. As a variant, the applicator member may comprise at least partially metallic or other inorganic material application elements and other non-metallic elements, in particular made of thermoplastic material.

Selon les réalisations, la tige est rigide, flexible, ou comporte une portion rigide et une portion flexible, la présence d'une portion flexible pouvant contribuer à augmenter l'amplitude des vibrations de l'organe d'application et/ou améliorer le confort à l'application.According to the embodiments, the rod is rigid, flexible, or comprises a rigid portion and a flexible portion, the presence of a flexible portion may contribute to increase the amplitude of the vibration of the applicator member and / or improve comfort to the application.

La portion flexible peut être réalisée dans un matériau élastiquement déformable, par exemple en élastomère, notamment un élastomère thermoplastique.The flexible portion may be made of an elastically deformable material, for example an elastomer, in particular a thermoplastic elastomer.

Par « élastiquement déformable », il faut comprendre que la portion flexible présente une certaine mémoire de forme. L'expression « élastiquement déformable » doit être comprise avec un sens large et couvre notamment le cas où la portion flexible reprend par élasticité, après avoir été déformée, une position qui n'est pas rigoureusement identique à sa position initiale, compte tenu par exemple de la nature du matériau utilisé pour réaliser la portion flexible et de la forme de celle-ci. La portion flexible est par exemple capable de fléchir pour permettre de modifier l'orientation de l'organe d'application sur plus de 30°, par exemple.By "elastically deformable", it should be understood that the flexible portion has a certain shape memory. The expression "elastically deformable" must be understood in a broad sense and covers in particular the case where the flexible portion resumes elastically, after having been deformed, a position which is not strictly identical to its initial position, taking into account, for example the nature of the material used to make the flexible portion and the shape thereof. The flexible portion is for example capable of bending to allow to change the orientation of the applicator member over more than 30 °, for example.

Par « partie rigide », il faut comprendre une partie qui ne se déforme pas sensiblement à l'application. Une partie rigide peut subir une légère déformation d'ensemble en cas de contrainte exercée avec les doigts sur celle-ci, par exemple.By "rigid part", it is necessary to understand a part that does not deform substantially to the application. A rigid part may undergo a slight overall deformation in the event of stress exerted with the fingers on it, for example.

La flexibilité de la portion flexible peut provenir de sa forme et/ou du ou des matériaux servant à la réaliser. La portion flexible est située ailleurs qu'au niveau de l'organe d'essorage éventuel, quand l'applicateur est en place.The flexibility of the flexible portion can come from its shape and / or the material or materials used to achieve it. The flexible portion is located elsewhere than at the possible wiper member, when the applicator is in place.

La portion flexible peut être située entre la portion rigide et l'organe d'application, de préférence au contact de ce dernier.The flexible portion may be located between the rigid portion and the applicator member, preferably in contact with the latter.

La portion flexible peut être moulée au contact de l'organe d'application, étant par exemple surmoulée sur l'organe d'application, notamment sur une queue en matériau inorganique, notamment métallique, de celui-ci. Une telle queue peut comporter des reliefs tels que des crans par exemple, améliorant l'accrochage de la partie en matériau inorganique, notamment métallique, sur la tige.The flexible portion may be molded in contact with the applicator member, for example being overmolded on the applicator member, in particular on a tail of inorganic material, in particular metal, of the latter. Such a tail may include reliefs such as notches for example, improving the attachment of the portion of inorganic material, in particular metal, on the rod.

La partie flexible de la tige peut être rapportée sur l'organe d'application, puis l'ensemble est monté sur la partie rigide de la tige. En variante, la partie flexible est moulée ou montée sur la partie rigide de la tige puis la tige reçoit l'organe d'application. En variante encore, la partie flexible est moulée au contact de l'organe d'application, puis l'ensemble est monté sur la tige.The flexible portion of the rod can be attached to the applicator member, then the assembly is mounted on the rigid portion of the rod. Alternatively, the flexible portion is molded or mounted on the rigid portion of the rod and the rod receives the applicator member. In another variant, the flexible portion is molded in contact with the applicator member, then the assembly is mounted on the rod.

Lorsque la partie flexible est moulée au contact de la tige, la matière utilisée pour former la partie flexible peut aussi servir à réaliser au moins une partie de l'organe d'application, par exemple au moins un élément d'application de l'organe d'application.When the flexible part is molded in contact with the rod, the material used to form the flexible part may also be used to produce at least a part of the applicator member, for example at least one element for applying the organ application.

La partie en matériau inorganique, notamment métallique, de l'organe d'application peut comporter un canal permettant à la matière synthétique de circuler pendant le moulage entre la cavité du moule servant à la fabrication de la portion flexible de la tige et celle servant à la réalisation d'une partie non métallique de l'organe d'application, par exemple d'un ou plusieurs éléments d'application en matière synthétique.The portion of inorganic material, in particular metal, of the applicator member may comprise a channel allowing the synthetic material to circulate during molding between the cavity of the mold used to manufacture the flexible portion of the rod and that serving to the production of a non-metallic part of the applicator member, for example one or more application elements made of synthetic material.

On peut encore monter à force, à froid où à chaud, la portion flexible dans ou atour de la portion rigide de la tige, et monter à force, à froid ou à chaud, une partie en matériau inorganique, notamment métallique, de l'organe d'application dans ou autour de la tige.It is also possible to force the flexible portion in or near the rigid portion of the rod to cold or hot, and to force, cold or hot, a portion of inorganic material, in particular metallic material, of the application member in or around the stem.

On peut disposer la source vibrante dans le dispositif de telle sorte qu'elle produise des vibrations coaxiales à l'axe longitudinal de l'organe d'application, ce qui peut s'avérer profitable au maquillage En variante, ces vibrations peuvent être transversales, notamment perpendiculaires à l'axe longitudinal de l'organe d'application.The vibrating source can be arranged in the device in such a way that it produces vibrations that are coaxial with the longitudinal axis of the applicator member, which can be advantageous for make-up. Alternatively, these vibrations can be transverse, especially perpendicular to the longitudinal axis of the applicator member.

Le dispositif peut comporter une capsule de fermeture d'un récipient contenant le produit à appliquer. Cette capsule peut constituer l'organe de préhension de l'applicateur. L'applicateur peut par exemple être séparé du récipient lors de l'application.The device may comprise a closure cap of a container containing the product to be applied. This capsule may constitute the gripping member of the applicator. The applicator may for example be separated from the container during application.

La capsule de fermeture peut comporter des moyens pour permettre sa fixation sur le récipient, par exemple une jupe de montage filetée ou être agencée pour s'encliqueter sur le récipient. La fermeture du récipient peut notamment être une fermeture étanche. La capsule de fermeture peut recevoir la source vibrante, dans certains exemples de réalisation.The closure cap may comprise means for allowing its attachment to the container, for example a threaded mounting skirt or be arranged to snap onto the container. The closure of the container may in particular be a sealed closure. The closure cap can receive the vibrating source, in some embodiments.

Comme mentionné plus haut, le dispositif comporte une tige, à une première extrémité de laquelle est fixé, de manière séparable ou non, l'organe d'application. La tige peut comporter une deuxième extrémité fixée à la capsule de fermeture du récipient contenant le produit ou à tout autre organe de préhension.As mentioned above, the device comprises a rod, at a first end of which is fixed, separably or not, the applicator member. The rod may have a second end attached to the closure cap of the container containing the product or any other gripping member.

La source vibrante peut être partiellement ou presque en totalité masquée par une paroi définissant un logement qui la reçoit, étant par exemple recouverte sur une majeure partie de sa longueur par l'organe de préhension lorsqu'elle est disposée dans le logement. Le logement du dispositif recevant la source vibrante est situé par exemple à une extrémité de ce dernier, débouchant par exemple dans une direction opposée à l'organe d'application.The vibrating source may be partially or almost completely masked by a wall defining a housing which receives it, being for example covered over a major part of its length by the gripping member when it is arranged in the housing. The housing of the device receiving the vibrating source is located for example at one end of the latter, opening for example in a direction opposite to the applicator member.

L'orientation de la source vibrante par rapport à la capsule de fermeture peut être fixe, et l'orientation de la capsule de fermeture par rapport à l'organe d'application peut éventuellement être réglable.The orientation of the vibrating source relative to the closure cap may be fixed, and the orientation of the closure cap relative to the applicator member may optionally be adjustable.

Un axe longitudinal de la source vibrante et un axe longitudinal de la capsule de fermeture du récipient peuvent être parallèles.A longitudinal axis of the vibrating source and a longitudinal axis of the closure cap of the container may be parallel.

Le dispositif peut comporter un organe d'essorage de l'organe d'application. L'organe d'essorage peut être fixe sur le récipient contenant le produit et essorer l'organe d'application lorsque ce dernier est retiré du récipient. L'organe d'essorage peut être rigide ou flexible.The device may comprise a wiper member of the applicator member. The wiper member may be fixed on the container containing the product and wring the applicator member when the latter is removed from the container. The wiper member may be rigid or flexible.

Le passage de l'organe d'application à travers l'organe d'essorage peut se faire alors que l'organe d'application est soumis à des vibrations.The passage of the applicator member through the wiper member can be done while the applicator member is subjected to vibrations.

Le dispositif peut comporter un contacteur permettant à l'utilisateur de mettre en marche ou non le moteur électrique. Ce contacteur peut comporter un levier moulé d'une seule pièce avec un support du moteur, notamment avec un boîtier de la source vibrante. Le dispositif peut comporter tout type d'interrupteur électrique, à contact fugitif ou permanent.The device may comprise a contactor allowing the user to start or not the electric motor. This contactor may comprise a lever molded in one piece with a motor support, in particular with a housing of the vibrating source. The device may include any type of electrical switch, fugitive or permanent contact.

Le produit peut être un produit cosmétique, de maquillage ou de soin, par exemple du mascara.The product may be a cosmetic, make-up or skincare product, for example mascara.

L'organe d'application peut être entièrement réalisé en un métal ou autre matériau inorganique, par exemple être usiné et/ou moulé en métal, ou être mixte métal/matière synthétique, notamment avec une partie métallique et une partie synthétique surmoulée sur la partie métallique ou rapportée dessus. La portion flexible de la tige peut être surinjectée sur la partie métallique de l'organe d'application, pour former également des éléments d'application, le cas échéant.The applicator member may be entirely made of a metal or other inorganic material, for example be machined and / or molded of metal, or be mixed metal / synthetic material, in particular with a metal part and a synthetic part overmolded on the part metallic or reported on it. The flexible portion of the rod may be surinjected on the metal part of the applicator member, to also form application elements, if any.

Un ou plusieurs éléments d'application peuvent être moulés en matière thermoplastique à travers un ou plusieurs canaux réalisés dans une partie en matériau inorganique, notamment métallique, de l'organe d'application.One or more application elements may be molded of thermoplastic material through one or more channels made in a portion of inorganic material, in particular metal, of the applicator member.

L'organe d'application peut comporter une pluralité de nervures transversales, par exemple annulaires, constituant des éléments d'application.The applicator member may comprise a plurality of transverse ribs, for example annular, constituting application elements.

L'organe d'application peut avoir un axe longitudinal curviligne. Pour obtenir un tel organe d'application, on peut par exemple procéder par emboutissage ou moulage.The applicator member may have a curvilinear longitudinal axis. To obtain such an applicator member, it is possible for example to proceed by stamping or molding.

L'organe d'application peut présenter deux faces d'application différentes, par exemple en raison de la longueur des éléments d'application sur chacune des faces et/ou de leur écartement, ou de l'emploi de métal pour les éléments d'application de l'une des faces et de matière synthétique pour l'autre. Les deux faces peuvent être situées à l'opposé d'une de l'autre, par exemple.The applicator member may have two different application faces, for example due to the length of the application elements on each of the faces and / or their spacing, or the use of metal for the elements of application. application of one of the faces and synthetic material for the other. The two faces may be located opposite one another, for example.

L'axe longitudinal de l'organe d'application peut être confondu avec celui de la tige. En variante, au moins une portion de l'organe d'application est excentrée relativement à l'axe longitudinal de la tige.The longitudinal axis of the applicator member may be coincident with that of the rod. Alternatively, at least a portion of the applicator member is eccentric relative to the longitudinal axis of the rod.

La portion flexible peut être centrée sur l'axe longitudinal de la portion rigide de la tige ou en variante être configurée pour excentrer l'organe d'application relativement à l'axe longitudinal de la tige.The flexible portion may be centered on the longitudinal axis of the rigid portion of the rod or alternatively be configured to offset the applicator member relative to the longitudinal axis of the rod.

L'organe d'application peut être à symétrie axiale par rapport à l'axe longitudinal de l'âme ou sans symétrie axiale par rapport à cet axe.The applicator member may be axially symmetrical with respect to the longitudinal axis of the core or without axial symmetry with respect to this axis.

Un applicateur selon l'invention peut avantageusement comporter une source vibrante. Toutefois, selon certains aspects de l'invention, l'applicateur ne comporte pas nécessairement de source vibrante.An applicator according to the invention may advantageously comprise a vibrating source. However, according to certain aspects of the invention, the applicator does not necessarily include a vibrating source.

Source vibranteVibrant source

Lorsque présente, la source vibrante est configurée pour générer des vibrations, par exemple des vibrations sinusoïdales, par exemple de fréquence comprise entre 0,5 et 1000 Hz, voire entre 1 et 500 Hz, mieux entre 10 et 300 Hz, par exemple entre 50 et 200 Hz.When present, the vibrating source is configured to generate vibrations, for example sinusoidal vibrations, for example of frequency between 0.5 and 1000 Hz, or even between 1 and 500 Hz, better between 10 and 300 Hz, for example between 50 and 200 Hz.

La fréquence peut varier en fonction de l'endroit ou de la pression avec laquelle les vibrations sont transmises. Les vibrations peuvent être produites de façon intermittente ou continue. La fréquence peut être choisie en fonction de la raideur de la tige ou de la flexibilité de l'organe d'application, de façon à permettre à l'organe d'application d'osciller en résonance.The frequency may vary depending on where or how the vibrations are transmitted. Vibrations can be produced intermittently or continuously. The frequency can be chosen according to the stiffness of the rod or the flexibility of the applicator member, so as to allow the application member to oscillate in resonance.

La source vibrante peut comporter un générateur de vibrations comprenant un moteur, par exemple un moteur en forme de disque, entraînant en rotation une masselotte, notamment une masselotte excentrée. La vitesse de rotation du moteur peut être comprise entre 2000 et 15000 tr/min, étant par exemple comprise entre 4500 et 10000 tr/min.The vibrating source may comprise a vibration generator comprising a motor, for example a disk-shaped motor, rotating a flyweight, including an eccentric flyweight. The rotational speed of the engine may be between 2000 and 15000 rpm, being for example between 4500 and 10000 rpm.

Le générateur de vibrations peut être autre, par exemple piézoélectrique, électromécanique ou à excentrique. Le générateur de vibrations peut encore comporter un moteur entraînant en rotation une roue dentée au contact d'un frotteur comportant une lame élastiquement déformable.The vibration generator may be other, for example piezoelectric, electromechanical or eccentric. The vibration generator may further include a motor rotating a gearwheel in contact with a shoe having an elastically deformable blade.

La tension d'alimentation utilisée peut aller de 1,5 Volts à 9 Volts par exemple. La source vibrante peut comprendre une source électrique telle qu'une pile bouton de 1,5 Volts. Le dispositif peut encore fonctionner sur secteur via un adapteur adéquat.The supply voltage used can range from 1.5 volts to 9 volts for example. The vibrating source may include an electrical source such as a 1.5 volt coin cell. The device can still operate on mains via a suitable adapter.

L'utilisation d'une pile bouton peut s'avérer avantageuse pour diminuer l'encombrement du dispositif. En cas d'utilisation d'une pile bouton et d'un moteur en forme de disque, la pile et le moteur peuvent être face à face, côte à côte ou la face de l'un peut être en regard de la tranche de l'autre.The use of a button cell can be advantageous to reduce the size of the device. When using a button cell and a motor disc shape, the stack and the motor can be face to face, side by side or the face of one can be next to the edge of the other.

La source vibrante peut comporter un organe de commande de son fonctionnement. Cet organe de commande peut être à déclenchement par enfoncement. L'organe de commande peut être à contact fugitif, le fonctionnement de la source vibrante cessant dès que l'organe de commande est relâché.The vibrating source may comprise a control member for its operation. This control member may be triggering by depression. The control member may be in fugitive contact, the operation of the vibrating source ceasing as soon as the control member is released.

L'applicateur peut être configuré pour permettre l'actionnement automatique de la source vibrante lorsque cette dernière est mise en place sur l'applicateur. En variante, l'actionnement de la source vibrante peut être déclenché par l'utilisateur en agissant sur un contacteur alors que cette dernière est en place.The applicator can be configured to allow the automatic actuation of the vibrating source when the latter is placed on the applicator. Alternatively, the actuation of the vibrating source can be triggered by the user by acting on a contactor while the latter is in place.

Les vibrations produites peuvent être orientées sensiblement parallèlement à l'axe longitudinal de l'applicateur et/ou parallèlement à l'axe longitudinal de l'organe d'application, lorsque celui-ci est rectiligne.The vibrations produced may be oriented substantially parallel to the longitudinal axis of the applicator and / or parallel to the longitudinal axis of the applicator member, when the latter is rectilinear.

En variante, les vibrations peuvent être orientées sensiblement perpendiculairement à l'axe longitudinal de l'applicateur et/ou perpendiculairement à l'axe longitudinal de l'organe d'application.Alternatively, the vibrations may be oriented substantially perpendicular to the longitudinal axis of the applicator and / or perpendicular to the longitudinal axis of the applicator member.

Les vibrations peuvent comporter une composante parallèle à l'axe longitudinal de la tige.The vibrations may comprise a component parallel to the longitudinal axis of the rod.

L'orientation des vibrations peut, le cas échéant, être modifiée en changeant la position de la source vibrante. L'orientation du moteur relativement à l'organe d'application peut être modifiée lorsque la source vibrante est déplacée.The orientation of the vibrations can, if necessary, be modified by changing the position of the vibrating source. The orientation of the motor relative to the applicator member may be changed when the vibrating source is moved.

La source vibrante peut être amovible ou non.The vibrating source can be removable or not.

Le moteur est avantageusement disposé dans un boîtier comportant deux demi-coquilles, par exemple en matière thermoplastique, reliées par une charnière film ou assemblées autrement. Le maintien de la source vibrante sur l'applicateur peut se faire par friction, encliquetage, vissage, verrouillage au moyen d'une pièce annexe, aimantation, par accrochage mécanique à crochets et boucles de type "Velcro" ou collage, par exemple à l'aide d'un adhésif repositionnable.The motor is advantageously arranged in a housing comprising two half-shells, for example made of thermoplastic material, connected by a film hinge or otherwise assembled. Maintaining the vibrating source on the applicator can be done by friction, snap-fastening, screwing, locking by means of an adjoining part, magnetization, by mechanical attachment with hooks and loops of the "Velcro" type or gluing, for example to the using a repositionable adhesive.

Le cas échéant, l'organe d'application peut être soumis aux vibrations d'une source vibrante montée sur un doigt de l'utilisateur, comme décrit dans la publication EP 1 920 676 .If necessary, the applicator member may be subjected to the vibrations of a vibrating source mounted on a finger of the user, as described in the publication EP 1 920 676 .

Dispositifsfeatures

On a représenté à la figure 1 un premier exemple d'un dispositif 1 de conditionnement et d'application réalisé conformément à l'invention. Ce dispositif 1 de conditionnement et d'application comporte un récipient 2 contenant un produit P à appliquer, et un applicateur 3 séparable du récipient 2, comportant une tige 4 munie à son extrémité distale d'un organe d'application 5 d'axe longitudinal X, par exemple rectiligne, et se raccordant à son extrémité proximale à un organe de préhension 6 constituant également une capsule de fermeture du récipient 2. Cette capsule de fermeture 6 peut être configurée, comme illustré sur la figure 6A, pour recouvrir une ouverture 7. Le récipient peut être pourvu d'un col fileté 12.We have shown figure 1 a first example of a device 1 for packaging and application made according to the invention. This device 1 for packaging and application comprises a container 2 containing a product P to be applied, and an applicator 3 separable from the container 2, comprising a rod 4 provided at its distal end with a longitudinal axis applicator member 5 X, for example rectilinear, and connected at its proximal end to a gripping member 6 also constituting a closure cap of the container 2. This closure cap 6 can be configured, as illustrated in FIG. Figure 6A to cover an opening 7. The container may be provided with a threaded neck 12.

Le récipient 2 est équipé d'un organe d'essorage 10 représenté à la figure 6A, par exemple constitué par une pièce en élastomère insérée dans le col 12 du récipient. L'organe d'essorage peut être conventionnel ou non, voire être réglable. La lèvre d'essorage 11 peut définir un orifice d'essorage de forme circulaire. L'organe de préhension 6 est agencé pour fermer de manière étanche le récipient 2 lors de son vissage sur le col, de façon connue en soi.The container 2 is equipped with a wiper member 10 shown in FIG. Figure 6A , for example constituted by an elastomer piece inserted into the neck 12 of the container. The wiper member may be conventional or not, or even be adjustable. The wiper lip 11 may define a wiping orifice of circular shape. The gripping member 6 is arranged to seal the container 2 during its screwing on the neck, in a manner known per se.

L'organe d'essorage 10 peut être réalisé par exemple avec une lèvre d'essorage de forme ondulée, comme illustré à la figure 6B, et décrit dans la demande US 2009/0028627 dont le contenu est incorporé par référence, ou avec une lèvre d'essorage pourvue de fentes se raccordant tangentiellement à l'orifice d'essorage, comme illustré à la figure 6C et décrit dans la demande US/20090052969 dont le contenu est incorporé par référence. On peut aussi utiliser un organe d'essorage en mousse ou à fente(s), lesquelles peuvent être concentriques à l'orifice d'essorage, le cas échéant.The wiper member 10 can be made for example with a wiping lip of corrugated shape, as illustrated in FIG. Figure 6B , and described in the application US 2009/0028627 whose contents are incorporated by reference, or with a spin lip provided with slots connecting tangentially to the wiping orifice, as illustrated in FIG. Figure 6C and described in the application US / 20090052969 whose contents are incorporated by reference. It is also possible to use a foam or slot wiper member (s), which may be concentric with the wiper orifice, if appropriate.

L'organe de préhension 6 peut définir, comme illustré, un logement pour recevoir une source vibrante 20 fixée de façon amovible sur l'applicateur. En variante, l'organe de préhension comporte une source vibrante non amovible.The gripping member 6 may define, as illustrated, a housing for receiving a vibrating source 20 removably attached to the applicator. In a variant, the gripping member comprises a non-removable vibrating source.

La source vibrante 20 comporte une surface de commande 21, définie par exemple par un contacteur à déclenchement par enfoncement.The vibrating source 20 comprises a control surface 21, defined for example by a depression trigger contactor.

L'organe de préhension 6 présente sur le côté, à partir de son extrémité proximale, une fenêtre 9 qui permet le passage d'un levier 41 définissant la surface de commande 21.The gripping member 6 has on the side, from its proximal end, a window 9 which allows the passage of a lever 41 defining the control surface 21.

Le boîtier 43 de la source vibrante 20 peut comporter, comme illustré sur la figure 5, un doigt 25 ou toute autre protubérance qui peut canaliser les vibrations de la source vibrante 20 vers l'organe d'application 5.The housing 43 of the vibrating source 20 may comprise, as illustrated in FIG. figure 5 , a finger 25 or any other protuberance which can channel the vibrations of the vibrating source 20 towards the applicator member 5.

Le doigt 25 peut venir au contact l'organe de préhension 6 dans le fond du logement recevant la source vibrante 20, pour transmettre les vibrations à l'organe d'application.The finger 25 can come into contact with the gripping member 6 in the bottom of the housing receiving the vibrating source 20, to transmit the vibrations to the applicator member.

Comme on peut le voir sur les figures 5A et 5B, le boîtier 43 de la source vibrante 20 peut être réalisé avec deux demi-coquilles 51 et 52 reliées par une charnière film 54 ou assemblées autrement, les deux demi-coquilles 51 et 52 étant par exemple moulées d'une seule pièce dans une matière thermoplastique ou en variante dans un autre matériau.As can be seen on the Figures 5A and 5B , the housing 43 of the vibrating source 20 can be made with two half-shells 51 and 52 connected by a film hinge 54 or otherwise assembled, the two half-shells 51 and 52 being for example molded in one piece in a material thermoplastic or alternatively in another material.

La demi-coquille 51 porte par exemple le doigt 25 tandis que l'autre demi-coquille présente une ouverture 56 demi-circulaire, adaptée à s'engager sur le doigt 25 lorsque le boîtier est fermé. Des picots d'assemblage 60, par exemple au nombre de deux, sont réalisés sur l'une des demi-coquilles, par exemple celle portant le levier 41, et peuvent s'engager dans des logements correspondants 62 de l'autre demi-coquille, situés sur le bord opposé à la charnière 54, pour assurer le maintien en position fermée du boîtier 43.The half-shell 51 carries for example the finger 25 while the other half-shell has a 56 opening half-circular, adapted to engage on the finger 25 when the housing is closed. Assembly pins 60, for example two in number, are made on one of the half-shells, for example that carrying the lever 41, and can engage in corresponding housing 62 of the other half-shell , located on the edge opposite the hinge 54, to maintain the closed position of the housing 43.

Lorsque le boîtier 43 est refermé, l'utilisateur peut appuyer sur la surface de commande 21 pour fermer le circuit électrique reliant une pile 80 à un moteur 70 et provoquer la mise en route de celui-ci. Le moteur 70 entraîne, dans l'exemple de la figure 5A, en rotation une masselotte 71 dont le centre d'inertie ne se trouve pas sur l'axe de rotation.When the housing 43 is closed, the user can press the control surface 21 to close the electrical circuit connecting a battery 80 to a motor 70 and cause the startup of it. The motor 70 drives, in the example of the Figure 5A , rotating a flyweight 71 whose center of inertia is not on the axis of rotation.

Cette masselotte 71 peut être externe au moteur ou interne à celui-ci, comme dans l'exemple de la figure 5B.This flyweight 71 may be external to the engine or internal to it, as in the example of the Figure 5B .

La source vibrante peut être proposée à l'utilisateur déjà montée sur l'applicateur, au sein d'un conditionnement qui est par exemple un coffret, un sachet, un blister, une boîte. En variante, la source vibrante peut être à l'état non assemblé avec l'applicateur ou le récipient au sein du conditionnement. La source vibrante peut être proposée avec au moins deux récipients ou deux organes d'application différents, au sein d'un même conditionnement.The vibrating source can be proposed to the user already mounted on the applicator, within a packaging that is for example a box, a bag, a blister, a box. Alternatively, the vibrating source may be unassembled with the applicator or container within the package. The vibrating source may be provided with at least two containers or two different application members, within the same package.

L'organe d'application 5 comporte des éléments d'application en saillie 100, au moins partiellement métalliques, ou en un autre matériau inorganique, supportés par une âme 101 qui peut également être métallique ou en un autre matériau inorganique.The applicator member 5 comprises projecting protruding members 100, at least partially of metal, or of another inorganic material, supported by a core 101 which may also be metallic or of another inorganic material.

Les éléments en saillie 100 peuvent avoir diverses formes et être disposés de diverses façons sur l'organe d'application 5, comme cela sera détaillé plus loin.The protruding elements 100 may have various shapes and be arranged in various ways on the applicator member 5, as will be detailed below.

La tige 4 peut, lorsque l'applicateur comporte une source vibrante, être réalisée entièrement dans un même matériau et être relativement rigide. Par exemple, en tenant d'une main l'organe de préhension 6 et en appuyant avec le pouce de l'autre main sur l'organe d'application, on peut faire fléchir légèrement la tige sans qu'il ne se forme d'angle au niveau de la jonction entre l'organe d'application et la tige.The rod 4 may, when the applicator comprises a vibrating source, be made entirely of the same material and be relatively rigid. For example, by holding the grasping member 6 with one hand and pressing with the thumb of the other hand on the applicator member, it is possible to bend the rod slightly without it being formed. angle at the junction between the applicator member and the rod.

Avec ou sans source vibrante, la tige peut avantageusement comporter une portion rigide 4a et une portion flexible 4b, par exemple réalisées dans des matières thermoplastiques différentes. La portion rigide 4a peut par exemple être réalisée dans une matière non élastomère, tandis que la portion 4b est réalisée dans un élastomère.With or without a vibrating source, the rod may advantageously comprise a rigid portion 4a and a flexible portion 4b, for example made of different thermoplastic materials. The rigid portion 4a may for example be made of a non-elastomeric material, while the portion 4b is made of an elastomer.

La flexibilité de la portion flexible peut être choisie en fonction des propriétés recherchées pour l'application, par exemple grâce au choix du ou des matériaux la constituant, notamment de leur dureté Shore. Les duretés des matériaux de la portion flexible de la tige et de la portion rigide adjacente de la tige peuvent être différentes.The flexibility of the flexible portion can be chosen according to the properties desired for the application, for example by the choice of the constituent material or materials, in particular their Shore hardness. The hardnesses of the materials of the flexible portion of the rod and the adjacent rigid portion of the rod may be different.

La portion flexible 4b peut être réalisée dans au moins partiellement un matériau de la liste suivante : matériau élastomère, thermoplastique, thermoplastique élastomère, PEBD, PVC, PU, les polyesters élastomères thermoplastiques, notamment les copolymères de téréphtalate de butène et de polytétraméthylèneoxyde glycol estérifié, Hytrel®, Febax®, Santoprene®, EPDM, PDM, EVA, SIS, SEBS, SBS, latex, silicone, nitrile, butyl, polyuréthane, polyéther bloc amide, polyester, cette liste n'étant pas limitative.The flexible portion 4b can be made in at least partially of a material from the following list: elastomeric material, thermoplastic, thermoplastic elastomer, LDPE, PVC, PU, thermoplastic elastomer polyesters, especially copolymers of butene terephthalate and polytetramethyleneoxide esterified glycol, Hytrel ® , Febax ® , Santoprene ® , EPDM, PDM, EVA, SIS, SEBS, SBS, latex, silicone, nitrile, butyl, polyurethane, polyether amide block, polyester, this list not being limiting.

La portion flexible 4b peut être réalisée avec un matériau dont la dureté est par exemple comprise entre 25 Shore A et 80 Shore D, voire entre 40 Shore A et 70 Shore D.The flexible portion 4b may be made of a material whose hardness is for example between 25 Shore A and 80 Shore D, or even between 40 Shore A and 70 Shore D.

La longueur totale apparente de la portion flexible 4b est par exemple comprise entre 10 et 35 mm.The total apparent length of the flexible portion 4b is for example between 10 and 35 mm.

Une plus grande dimension transversale extérieure de la portion flexible 4b est par exemple comprise entre 1,5 et 10 mm.A larger external transverse dimension of the flexible portion 4b is for example between 1.5 and 10 mm.

La flexibilité de la portion flexible 4b peut varier en fonction de la section transversale et du profil de la portion flexible.The flexibility of the flexible portion 4b may vary depending on the cross section and the profile of the flexible portion.

La portion flexible 4b peut avoir une section transversale pleine ou creuse et de forme variée, par exemple de forme choisie dans la liste suivante : polygonale, carrée, rectangulaire, triangulaire, circulaire, non circulaire, oblongue, ovale, elliptique, crénelée, en forme d'étoile, avec une ou plusieurs gorges, annulaires ou axiales.The flexible portion 4b may have a solid or hollow cross section and of varied shape, for example of a shape chosen from the following list: polygonal, square, rectangular, triangular, circular, non-circular, oblong, oval, elliptical, crenellated, shaped star, with one or more grooves, annular or axial.

La portion flexible 4b peut être symétrique de révolution autour de l'axe longitudinal de la tige.The flexible portion 4b may be symmetrical in revolution about the longitudinal axis of the rod.

La portion flexible 4b peut présenter un rétreint, le cas échéant. Ce rétreint peut être de forme annulaire. Ainsi, dans des exemples de réalisation, la portion flexible de la tige est en forme de diabolo ou présente une gorge annulaire en forme de créneau.The flexible portion 4b may have a necking, if any. This shrinkage may be annular. Thus, in exemplary embodiments, the flexible portion of the rod is diabolo-shaped or has a crenellated annular groove.

La portion flexible 4b peut encore être non symétrique de révolution. Une telle forme peut permettre d'obtenir une flexibilité de la tige qui est variable selon la direction d'inclinaison de l'élément d'application par rapport à sa configuration initiale.The flexible portion 4b can still be non-symmetrical of revolution. Such a shape may make it possible to obtain a flexibility of the rod which is variable according to the direction of inclination of the applicator element with respect to its initial configuration.

Quelle que soit la manière dont la tige est réalisée, la portion flexible 4b peut être configurée de telle sorte que l'organe d'application puisse être incliné de manière réversible lors de l'application, par exemple de plus de 10°, mieux 15°, encore mieux 30°, voire plus de 45° ou 60°, par rapport à une configuration initiale de repos dans laquelle l'organe d'application et la partie rigide de la tige sont par exemple sensiblement alignés.Whatever the way the rod is made, the flexible portion 4b can be configured so that the applicator member can be reversibly inclined during application, for example more than 10 °, better 15 °, even better 30 °, or more than 45 ° or 60 °, with respect to an initial configuration of rest in which the applicator member and the rigid portion of the rod are for example substantially aligned.

La ou les parties rigides de la tige peuvent être réalisées dans un matériau thermoplastique, notamment l'un des matériaux choisis dans la liste suivante : PEHD, PEBD, PE linéaire, PT, PP, POM, PA, PET, PBT, cette liste n'étant pas limitative.The rigid part (s) of the rod may be made of a thermoplastic material, in particular one of the materials selected from the following list: HDPE, LDPE, linear PE, PT, PP, POM, PA, PET, PBT, this list n not being limiting.

L'organe d'application 5 peut être réalisé de façon monolithique en métal, comme illustré à la figure 5 par exemple, ce métal étant choisi par exemple parmi l'aluminium, les alliages d'aluminium, l'acier, le cuivre , le laiton, le bronze, le titane, le tungstène, le fer ou l'argent, entre autres. Le métal peut être magnétisable. L'organe d'application peut être constitué au moins en partie de ferrites ou de terres rares, voire totalement de ferrites ou de terres rares. L'organe d'application peut être en verre ou en céramique.The applicator member 5 may be made monolithically of metal, as illustrated in FIG. figure 5 for example, this metal being chosen for example from aluminum, aluminum alloys, steel, copper, brass, bronze, titanium, tungsten, iron or silver, among others. The metal can be magnetizable. The application member may consist at least in part of ferrites or rare earths, or totally ferrites or rare earths. The applicator member may be glass or ceramic.

L'organe d'application 5 peut être réalisé avec un embout 110 de fixation sur la tige 4, cet embout 110 pouvant comporter tout type de relief 111 adapté à l'ancrage dans la tige 4, éventuellement dans ou sur la portion flexible 4b lorsque celle-ci existe.The applicator member 5 can be made with a fastening tip 110 on the rod 4, this tip 110 possibly having any type of relief 111 adapted for anchoring in the rod 4, possibly in or on the flexible portion 4b when this one exists.

Comme exemple de relief 111, on peut citer par exemple un filetage un ou plusieurs bossages ou crans tel qu'illustré notamment aux figures 21 et 22. Pour créer un relief en quadrillage tel qu'illustré à la figure 21, on peut par exemple réaliser deux filets hélicoïdaux croisés en sens inverses, par décolletage ou autre technique adaptée.As an example of relief 111, there may be mentioned for example a thread one or more bosses or notches as illustrated in particular in FIGS. Figures 21 and 22 . To create a grid pattern as illustrated in figure 21 it is possible, for example, to produce two helical threads crossed in opposite directions, by bar turning or other suitable technique.

Les éléments en saillie 100 peuvent se présenter sous la forme de nervures séparées les unes des autres par des gorges transversales 103, qui s'étendent par exemple tout autour de l'âme 101.The protruding elements 100 may be in the form of ribs separated from each other by transverse grooves 103, which extend for example all around the core 101.

Le profil des éléments en saillie 100, lorsque ceux-ci comportent des nervures annulaires s'étendant autour de l'axe longitudinal de l'âme, continues ou interrompues, peut être varié et n'est pas limité à la forme circulaire illustrée à la figure 9A.The profile of the projecting elements 100, when they comprise annular ribs extending around the longitudinal axis of the core, continuous or interrupted, can be varied and is not limited to the circular shape illustrated in FIG. Figure 9A .

Le contour d'un élément en saillie 100 peut par exemple être polygonal, par exemple triangulaire comme illustré à la figure 9B, carré comme illustré à la figure 9C, hexagonal comme illustré à la figure 9D, les sommets pouvant être arrondis ou pointus.The outline of a projecting element 100 may for example be polygonal, for example triangular as illustrated in FIG. Figure 9B square as shown in Figure 9C , hexagonal as shown in Figure 9D , the tops may be rounded or pointed.

Le contour d'un élément en saillie 100 peut encore être en forme d'étoile, comme illustré aux figures 9E à 9G, avec par exemple trois branches comme c'est le cas sur la figure 9E, quatre branches comme c'est le cas sur la figure 9F, ou cinq branches comme c'est le cas sur la figure 9G. Les branches peuvent former des rangées de dents sur l'organe d'application.The outline of a projecting element 100 can still be star-shaped, as illustrated in FIGS. Figures 9E to 9G , for example with three branches as is the case on the Figure 9E , four branches as is the case on the figure 9F , or five branches as is the case on the Figure 9G . The branches can form rows of teeth on the applicator member.

L'organe d'application peut être dissymétrique ou excentré.The applicator member may be asymmetrical or eccentric.

Les côtés reliant deux branches adjacentes peuvent être arrondis, concaves vers l'extérieur, comme illustré sur la figure 9E ou 9F, ou sous forme de dièdre rentrant, comme illustré sur la figure 9G.The sides connecting two adjacent branches may be rounded, concave outwards, as shown in the diagram. Figure 9E or 9F , or as a returning dihedral, as shown on the Figure 9G .

Dans l'exemple de la figure 9H, le contour est ovale, par exemple de forme elliptique.In the example of the figure 9H the outline is oval, for example of elliptical shape.

Dans l'exemple de la figure 9I, le contour comporte des côtés 103 disposés comme un polygone, et reliés entre eux par des pointes 104. Chaque côté 103 se prolonge jusqu'au sommet de la pointe 104 associée Toutes les pointes 104 peuvent être orientées dans le même sens circonférentiel autour de l'âme 101.In the example of the figure 9I , the contour comprises sides 103 arranged as a polygon, and interconnected by points 104. Each side 103 extends to the top of the tip 104 associated All points 104 can be oriented in the same circumferential direction around the soul 101.

Le contour peut également présenter une forme générale de sablier, comme illustré sur la figure 9J, avec par exemple deux ailes diamétralement opposées, qui peuvent être reliées uniquement par l'âme ou se raccorder autour de l'âme.The outline may also have a general hourglass shape, as illustrated on the Figure 9J , with for example two diametrically opposed wings, which can be connected only by the soul or connect around the soul.

Dans l'exemple de la figure 9L, le contour comporte des portions arrondies, notamment circulaires 106, et des portions rectilignes 107 qui se raccordent aux portions arrondies en formant des pointes 108.In the example of the figure 9L , the contour comprises rounded portions, in particular circular 106, and rectilinear portions 107 which are connected to the rounded portions by forming points 108.

Le contour d'un élément en saillie, lorsqu'observé selon l'axe longitudinal de l'âme, peut d'une manière générale être à symétrie axiale par rapport à l'axe longitudinal de l'âme ou sans symétrie axiale par rapport à l'axe longitudinal de l'âme.The contour of a protruding element, when observed along the longitudinal axis of the core, may in general be axially symmetrical with respect to the longitudinal axis of the core or without axial symmetry with respect to the longitudinal axis of the soul.

On a illustré sur la figure 9L la possibilité de réaliser l'organe d'application avec à la fois une partie en matériau inorganique, notamment métallique, et une partie en matériau organique, notamment thermoplastique.We illustrated on the figure 9L the possibility of producing the application member with both a portion of inorganic material, in particular metal, and a portion of organic material, especially thermoplastic.

La partie métallique comporte par exemple des éléments d'application 100 sous la forme de nervures formant saillie sur au moins un coté de l'organe d'application, ces éléments étant reliés par une âme 101.The metal part comprises, for example, application elements 100 in the form of ribs projecting on at least one side of the applicator member, these elements being connected by a core 101.

La partie non métallique 148 est réalisée par exemple dans une matière thermoplastique et peut comporter des éléments d'application 149, qui peuvent par exemple dépasser de la partie métallique d'un coté au moins de l'organe d'application, par exemple sur deux cotés opposés comme illustré à la figure 9L. Sur cette figure, l'organe d'application présente deux cotés opposés pourvus d'éléments d'application métalliques 100 et entre ces deux cotés opposés, deux autres cotés opposés pourvus des éléments d'application non métalliques 149. La partie non métallique 148 peut être surmoulée sur la partie métallique.The non-metallic part 148 is made for example of a thermoplastic material and may comprise application elements 149, which may for example protrude from the metal part on at least one side of the applicator member, for example over two opposite sides as shown in the figure 9L . In this figure, the applicator member has two opposite sides provided with metal application elements 100 and between these two opposite sides, two other opposite sides provided with non-metallic application elements 149. The non-metallic part 148 can be overmolded on the metal part.

Dans les exemples des figures 9A à 9K, on a représenté l'âme 101 avec une section transversale circulaire ou ovale mais cette section peut encore être de forme polygonale ou autre, pleine ou creuse. De même, les éléments en saillie peuvent être pleins ou ajourés.In the examples of Figures 9A to 9K the core 101 is shown with a circular or oval cross-section, but this section may also be of polygonal or other shape, solid or hollow. Similarly, the projecting elements can be full or perforated.

Lorsque l'âme et/ou les éléments en saillie sont ajourés, une matière de comblement non métallique peut éventuellement les remplir, par exemple une matière thermoplastique.When the core and / or the projecting elements are perforated, a nonmetallic filler may optionally fill them, for example a thermoplastic material.

Lorsqu'observé de côté, perpendiculairement à l'axe longitudinal, l'organe d'application peut présenter une surface enveloppe ayant différents profils.When viewed from the side, perpendicular to the longitudinal axis, the applicator member may have an envelope surface having different profiles.

La surface enveloppe, qui est définie par les contours libres des éléments en saillie 100, peut, sur au moins une portion de la longueur de l'organe d'application, par exemple plus de la moitié de sa longueur, être cylindrique, de section circulaire ou non, la section transversale de la surface enveloppe pouvant notamment être l'une de celles décrites aux figures 9A à 9L.The envelope surface, which is defined by the free contours of the protruding elements 100, may, over at least a portion of the length of the applicator member, for example more than half of its length, be cylindrical, of section circular or not, the cross-section of the envelope surface may in particular be one of those described in Figures 9A to 9L .

La portion distale de la surface enveloppe peut être effilée en direction de l'extrémité distale de l'organe d'application, comme illustré à la figure 7. Il peut en être de même de l'extrémité proximale de la surface enveloppe, par exemple dans le but de faciliter la traversée de l'organe d'essorage, aussi bien lors de l'introduction dans le récipient que lors de l'extraction de celui-ci.The distal portion of the envelope surface may be tapered toward the distal end of the applicator member as shown in FIG. figure 7 . It may be the same for the proximal end of the envelope surface, for example in order to facilitate the crossing of the wiper member, both during the introduction into the container and during the extraction of this one.

La surface enveloppe E peut passer par un extremum, par exemple un maximum, entre les extrémités proximale et distale de la partie de l'organe d'application servant à l'application du produit, comme illustré à la figure 10.The envelope surface E may pass through an extremum, for example a maximum, between the proximal and distal ends of the portion of the applicator member for applying the product, as illustrated in FIG. figure 10 .

L'écartement entre les éléments en saillie 100 peut ne pas être constant le long de l'axe longitudinal de l'organe d'application, comme illustré à la figure 11. Par exemple, l'écartement peut être réduit à proximité des extrémités proximale et distale de la partie de l'organe d'application servant à l'application du produit et plus grand dans une portion médiane de l'organe d'application.The spacing between the protruding members 100 may not be constant along the longitudinal axis of the applicator member, as illustrated in FIG. figure 11 . For example, the gap may be reduced near the proximal and distal ends of the portion of the applicator member for application of the product and larger in a medial portion of the applicator member.

Les figures 10 et 11 illustrent la possibilité de réaliser les éléments en saillie avec une forme effilée vers un sommet 106, par exemple avec deux faces 107 de part et d'autre du sommet 106 qui sont coniques autour de l'axe longitudinal X de l'organe d'application. Ainsi, deux faces 107 adjacentes appartenant à deux éléments en saillie consécutifs biconiques peuvent former une gorge 103 en V, divergeant vers l'extérieur.The figures 10 and 11 illustrate the possibility of producing the projecting elements with a tapered shape towards a vertex 106, for example with two faces 107 on either side of the vertex 106 which are conical around the longitudinal axis X of the application member . Thus, two adjacent faces 107 belonging to two consecutive biconical protruding elements may form a groove 103 V, diverging outwardly.

Bien entendu, un écartement variable entre les éléments en saillie 100 le long de l'élément d'application peut être réalisé, avec toute forme d'élément en saillie.Of course, a variable spacing between the projecting elements 100 along the applicator element can be realized, with any form of protruding element.

Les éléments en saillie 100 et/ou l'âme 101 de l'organe d'application peuvent recevoir un flocage 120, comme illustré à la figure 12.The protruding elements 100 and / or the core 101 of the applicator member may receive a flocking 120, as illustrated in FIG. figure 12 .

Le flocage 120 peut comporter un seul type de floc ou un mélange de flocs.The flocking 120 may comprise a single type of floc or a mixture of flocks.

On a représenté aux figures 13 à 17 différents exemples de configurations d'éléments en saillie 100, parmi d'autres.Representatives Figures 13 to 17 various examples of surface element configurations 100, among others.

Les éléments en saillie, qu'ils soient métalliques ou non, peuvent avoir des sommets arrondis, comme illustré à la figure 13, et être orientés par exemple chacun perpendiculairement à l'axe longitudinal X, ayant par exemple une forme symétrique par rapport à un plan médian perpendiculaire à cet axe X, lequel peut être rectiligne ou curviligne.The protruding elements, whether metallic or not, may have rounded tops, as illustrated in FIG. figure 13 , and be oriented for example each perpendicular to the longitudinal axis X, having for example a symmetrical shape with respect to a median plane perpendicular to this axis X, which may be rectilinear or curvilinear.

On peut réaliser l'organe d'application 5 avec des éléments en saillie, qu'ils soient métalliques ou non, qui sont espacés les uns des autres le long de l'âme 101, comme représenté à la figure 14, ou qui se touchent, comme représenté par exemple aux figures 10 et 12.The applicator member 5 can be made with projecting elements, whether metallic or not, which are spaced apart from each other along the core 101, as shown in FIG. figure 14 , or which touch each other, as represented for example by figures 10 and 12 .

Sur les figures 15 à 17, on a illustré la possibilité pour l'organe d'application 5 de comporter des éléments en saillie, qu'ils soient métalliques ou non, de formes différentes, par exemple une succession d'éléments en saillie chacun de forme biconique alternant avec des éléments en saillie chacun en forme de tronçon de cylindre.On the Figures 15 to 17 the possibility has been illustrated for the applicator member 5 to comprise projecting elements, whether metallic or not, of different shapes, for example a succession of projecting elements each of biconical shape alternating with elements projecting each in the form of a cylinder section.

Les éléments en saillie, lorsqu'ils sont de formes différentes, peuvent avoir des hauteurs différentes. Par exemple peuvent être présents sur l'organe d'application des éléments en saillie de hauteurs respectives h1 et h2 différentes, les éléments de plus grande hauteur h1 alternant par exemple avec les éléments de plus petite hauteur h2.The projecting elements, when they are of different shapes, can have different heights. For example may be present on the application member of the projecting elements of respective heights h1 and h2 different, the elements of greater height h1 alternating for example with the elements of smaller height h2.

Les éléments en saillie de plus petite hauteur peuvent être réalisés, comme illustré à la figure 17, en tronquant le sommet des éléments de plus grande hauteur, par exemple par usinage.The projecting elements of smaller height can be made, as illustrated in FIG. figure 17 truncating the top of the elements of greater height, for example by machining.

L'organe d'application 5 peut recevoir un traitement de surface ou un revêtement de surface, afin par exemple de former en surface une couche 125 d'un autre métal que celui dans lequel est réalisé l'organe d'application dans sa partie sous-jacente, par exemple un placage d'un métal noble, par exemple de l'or, de l'argent ou du tungstène. La couche 125 peut également être formée par un traitement thermique du métal ou être constituée par une couche d'un oxyde, par exemple afin de conférer plus de glissant ou plus d'accroche à l'organe d'application, ou de modifier sa couleur. L'organe d'application peut par exemple être réalisé en aluminium anodisé en surface.The applicator member 5 can receive a surface treatment or a surface coating, in order, for example, to form on the surface a layer 125 of a metal other than that in which the application member is made in its part under -cente, for example a veneer of a noble metal, for example gold, silver or tungsten. The layer 125 can also be formed by a heat treatment of the metal or be constituted by a layer of an oxide, for example in order to impart more slippery or more grip to the application member, or to change its color . The application member may for example be made of anodized aluminum surface.

Le cas échéant, l'organe d'application peut comporter des éléments en saillie qui sont revêtus en surface d'un vernis et/ou d'une peinture ou d'un revêtement non métallique, par exemple élastomère ou PTFE.Where appropriate, the applicator member may comprise projecting elements which are coated on the surface with a varnish and / or with a non-metallic paint or coating, for example an elastomer or PTFE.

L'organe d'application peut recevoir un traitement de passivation ou d'anodisation. L'organe d'application peut être sablé ou traité par plasma ou érodé autrement.The application member may be passivated or anodized. The applicator member may be sanded or plasma treated or otherwise eroded.

L'organe d'application 5 peut être réalisé avec toute forme facilitant sa fixation sur la tige 4.The applicator member 5 can be made with any shape facilitating its attachment to the rod 4.

Par exemple, l'organe d'application 5 peut être creux et présenter une cavité 130 dans laquelle peut être sous-injectée la matière de la portion flexible 4b de la tige, comme illustré à la figure 19. La cavité 130 peut par exemple s'étendre sur plus de la majeure partie de la longueur de la partie utile à l'application de l'organe d'application 5.For example, the applicator member 5 may be hollow and may have a cavity 130 in which the material of the flexible portion 4b of the rod may be under-injected, as illustrated in FIG. figure 19 . The cavity 130 may for example extend over more than the major part of the length of the part useful for the application of the applicator member 5.

On voit sur la figure 19 que la partie flexible 4b peut être réalisée, le cas échéant, avec une gorge 135 située entre l'organe d'application 5 et la portion rigide 4a de la tige. On voit également sur cette figure que la fixation de la portion flexible 4b sur la portion rigide 4a peut s'effectuer par insertion d'un embout 139 de la portion flexible 4b dans un logement 140 de la portion rigide 4a.We see on the figure 19 that the flexible portion 4b can be made, if necessary, with a groove 135 located between the applicator member 5 and the rigid portion 4a of the rod. It is also seen in this figure that the fixing of the flexible portion 4b on the rigid portion 4a can be performed by inserting a nozzle 139 of the flexible portion 4b in a housing 140 of the rigid portion 4a.

Sur la figure 20, on a illustré le fait que la portion flexible 4b peut comporter un embout 142 inséré dans un logement 143 formé à l'extrémité proximale de l'organe d'application 5.On the figure 20 it is illustrated that the flexible portion 4b may comprise a tip 142 inserted in a housing 143 formed at the proximal end of the applicator member 5.

L'organe d'application 5 peut être réalisé avec des éléments en saillie 100 de faible hauteur, formés par exemple par un quadrillage réalisé à la surface de l'organe d'application.The applicator member 5 can be made with projecting elements 100 of small height, formed for example by a grid formed on the surface of the applicator member.

On a illustré à la figure 22 la possibilité pour les éléments en saillie 100 de s'étendre selon des plans respectifs inclinés par rapport à l'axe longitudinal X de l'âme 101 de l'organe d'application 5.We illustrated at the figure 22 the possibility for the protruding elements 100 to extend in respective planes inclined relative to the longitudinal axis X of the core 101 of the applicator member 5.

On a également illustré sur cette figure la possibilité pour la surface enveloppe E de passer par un minimum entre les extrémités proximale et distale de la surface d'application, la surface enveloppe ayant une forme générale de cacahuète.This figure also illustrates the possibility for the envelope surface E to pass through a minimum between the proximal and distal ends of the application surface, the envelope surface having a general shape of peanut.

On a illustré à la figure 23 la possibilité de cintrer l'organe d'application 5 pour donner à l'axe longitudinal X de l'âme une forme curviligne, l'axe longitudinal X ayant par exemple une première courbure dans un sens, puis une deuxième courbure dans le sens contraire, dans un même plan.We illustrated at the figure 23 the possibility of bending the applicator member 5 to give the longitudinal axis X of the core a curvilinear shape, the longitudinal axis X having for example a first curvature in one direction, then a second curvature in the opposite direction , in the same plane.

L'extrémité distale de l'organe d'application peut se situer ou non sur l'axe longitudinal de la tige 4.The distal end of the applicator member may or may not lie on the longitudinal axis of the rod 4.

L'organe d'application 5 peut avoir ou non une portion d'âme d'axe rectiligne parallèle à l'axe longitudinal de la tige.The applicator member 5 may or may not have a core portion of rectilinear axis parallel to the longitudinal axis of the rod.

Sur la figure 24, on a illustré la possibilité pour l'âme d'avoir une section transversale qui varie le long de l'axe longitudinal de l'âme, avec par exemple des éléments en saillie 100 de hauteur constante. Ainsi, le profil de la surface enveloppe E peut être variable suivant l'évolution de la section transversale de l'âme.On the figure 24 the possibility has been illustrated for the soul to have a cross section which varies along the longitudinal axis of the core, with for example protruding elements 100 of constant height. Thus, the profile of the envelope surface E may be variable depending on the evolution of the cross section of the core.

Pour réaliser un organe d'application 5, on peut injecter du métal dans un moule. On peut éventuellement, après l'étape de moulage, usiner l'organe d'application.To achieve an applicator member 5, metal can be injected into a mold. It is possible, after the molding step, to machine the applicator member.

On peut partir d'un barreau, notamment un barreau cylindrique de révolution, usiner le barreau pour former un embout servant à la fixation sur la tige, puis usiner les disques formant les éléments en saillie servant à l'application. Cet usinage peut s'effectuer par exemple en entraînant en rotation sur lui-même le barreau ou à l'aide d'un outil entraîné en rotation autour du barreau. On peut ensuite, le cas échéant, donner à l'organe d'application la section souhaitée, par fraisage par exemple, notamment une section telle que l'une de celles représentées aux figures 9A à 9L.One can start from a bar, including a cylindrical bar of revolution, machining the bar to form a tip for fixing on the rod, then machining the disks forming the projecting elements for the application. This machining can be performed for example by driving in rotation on itself the bar or with a tool driven in rotation around the bar. Then, if necessary, the desired section may be given to the application member, for example by milling, in particular a section such as one of those shown in FIGS. Figures 9A to 9L .

Ensuite, le cas échéant, l'organe d'application peut subir un traitement de surface, par exemple un sablage ou autre traitement. On peut aussi partir d'un barreau métallique, comme illustré à la figure 33A, usiner l'embout 110 servant à la fixation sur la tige, comme illustré à la figure 33B, puis la pointe 150 de l'organe d'application, comme illustré à la figure 33C, et réaliser ensuite des reliefs à la surface de l'organe d'application, par décolletage ou autre technique d'usinage, par exemple attaque laser ou chimique.Then, if necessary, the application member may undergo a surface treatment, for example sandblasting or other treatment. We can also start from a metal bar, as shown in figure 33A machining the tip 110 for attachment to the rod, as shown in FIG. figure 33B , then the tip 150 of the applicator member, as illustrated in FIG. figure 33C , and then perform reliefs on the surface of the applicator member, by machining or other machining technique, for example laser or chemical attack.

On peut par exemple, comme illustré à la figure 33D, réaliser un filet hélicoïdal 155 le long de l'organe d'application, entre la pointe 150 et l'embout 110, puis, une fois ce filet réalisé, décolleter les éléments en saillie, comme illustré à la figure 33E.For example, as illustrated in figure 33D , make a helical thread 155 along the applicator member, between the tip 150 and the tip 110, then, once this thread is made, cut the protruding elements, as shown in FIG. figure 33E .

On peut, grâce à l'utilisation d'un métal usinable, réaliser un organe d'application avec des formes nouvelles, et par exemple réaliser plusieurs reliefs successivement sur l'organe d'application pour combiner toutes formes de nervures et gorgesIt is possible, thanks to the use of a machinable metal, to make an application member with new shapes, and for example to make several reliefs successively on the applicator member to combine all forms of ribs and grooves.

D'une façon générale, la hauteur des éléments en saillie, qu'ils soient métalliques ou non, mesurée par rapport à l'âme, peut être constante ou non pour un même élément en saillie, lorsque l'on se déplace autour de l'axe longitudinal de l'âme, et la hauteur moyenne peut par exemple varier de 0,5 mm à 5 mm.In general, the height of the protruding elements, whether they are metallic or not, measured with respect to the core, can be constant or not for the same projecting element, when one moves around the longitudinal axis of the core, and the average height may for example vary from 0.5 mm to 5 mm.

L'épaisseur d'un élément en saillie 100, mesurée parallèlement à l'axe longitudinal de l'âme, peut être comprise par exemple entre 0,2 mm et 1 mm, par exemple entre 0,5 et 0,6 mm, notamment 0,55 mm. Par exemple, l'épaisseur des nervures servant d'éléments d'application, notamment lorsqu'elles sont sous forme de disques, peut être d'au moins 0,2 mm au moins et les gorges formées entre deux nervures adjacentes peuvent être d'épaisseur comprise entre 0,5 et 3 mm. La base d'une nervure, au niveau du raccordement avec l'âme, peut avoir une épaisseur allant par exemple jusqu'à 3 mm.The thickness of a projecting element 100, measured parallel to the longitudinal axis of the core, may be for example between 0.2 mm and 1 mm, for example between 0.5 and 0.6 mm, in particular 0.55 mm. For example, the thickness of the ribs serving as application elements, especially when they are in the form of disks, can be at least 0.2 mm at least and the grooves formed between two adjacent ribs may be between 0.5 and 3 mm thick. The base of a rib, at the connection with the core, may have a thickness ranging for example up to 3 mm.

Le nombre d'éléments en saillie, sur l'organe d'application, est compris par exemple entre 3 et 600, par exemple 3 et 40.The number of protruding elements on the applicator member is for example between 3 and 600, for example 3 and 40.

Par exemple, un organe d'application ayant une partie venant au contact des cils pour l'application de 20 mm de long peut comporter 25 éléments d'application constitués par les crêtes d'un filetage, et pour 35mm de long entre 40 et 45 éléments d'application.For example, an applicator member having an eyelash-contacting portion for the application of 20 mm in length may have 25 application members constituted by the ridges of a thread, and for 35 mm long between 40 and 45 application elements.

Le poids de l'organe d'application est par exemple supérieur à 0,5 g et par exemple compris entre 0,7 et 3,5 g.The weight of the applicator member is, for example, greater than 0.5 g and for example between 0.7 and 3.5 g.

On peut, le cas échéant, réaliser l'organe d'application non seulement avec des éléments en saillie au moins partiellement métalliques, mais également avec des éléments en saillie non métalliques, réalisé par exemple par surinjection d'une matière thermoplastique sur l'organe d'application. Cela peut permettre de bénéficier sur l'organe d'application de plusieurs zones ayant des caractéristiques de chargement en produit et/ou de peignage et d'application du produit différentes.If necessary, the applicator member can be made not only with projecting elements which are at least partially metallic, but also with non-metallic projecting elements, for example made by over-injection of a thermoplastic material onto the body. application. This can make it possible to benefit on the application member of several zones having characteristics of product loading and / or combing and application of the different product.

On peut utiliser, pour réaliser l'organe d'application au moins en partie, une matière thermoplastique comportant une charge de particules métalliques, de façon à augmenter la densité des éléments en saillie qui ne seraient pas entièrement réalisés en métal. La proportion de particules métalliques peut aller de 0,5 à 70% en poids.To achieve the applicator member at least in part, a thermoplastic material having a charge of metal particles can be used to increase the density of the protruding elements which are not entirely made of metal. The proportion of metal particles can range from 0.5 to 70% by weight.

On peut réaliser les éléments en saillie en rapportant sur une âme, qui peut être métallique ou non, des disques métalliques.The projecting elements can be made by connecting a metallic disk to a core, which may be metallic or not.

On peut réaliser sur l'un des exemples d'organes d'application représentés sur le dessin, une ou plusieurs gorges longitudinales supplémentaires parallèles à l'axe longitudinal de l'âme, formant ainsi des encoches additionnelles sur l'organe d'application. L'invention n'est pas limitée aux exemples décrits. On peut notamment combiner entre elles les particularités de réalisation illustrées au sein d'exemples non illustrés. Par exemple, l'un quelconque des organes d'application peut être muni de n'importe lequel des moyens de fixation de l'organe d'application sur la tige, représentés sur le dessin.One or more additional longitudinal grooves parallel to the longitudinal axis of the core can be made on one of the application members shown in the drawing, thus forming additional notches on the applicator member. The invention is not limited to the examples described. In particular, the exemplary embodiments illustrated in non-illustrated examples can be combined. For example, any one of the application members may be provided with any of the fastening means of the applicator member on the rod, shown in the drawing.

La tige peut être réalisée avec ou sans portion flexible 4b pour l'un quelconque des organes d'application représentés sur le dessin.The rod may be made with or without a flexible portion 4b for any of the application members shown in the drawing.

La surface enveloppe peut avoir un plus grand diamètre supérieur ou non à celui de la tige.The envelope surface may have a larger diameter greater or less than that of the rod.

L'organe d'application peut éventuellement être matricé pour former un angle à sa base.The applicator member may optionally be stamped to form an angle at its base.

L'organe d'application peut avoir des éléments en saillie formés par un ou plusieurs filets hélicoïdaux.The applicator member may have projecting elements formed by one or more helical threads.

Lorsque l'organe d'application comporte un filet hélicoïdal, celui-ci peut progresser dans le sens horaire et anti-horaire vers l'extrémité distale. L'organe d'application peut comporter le cas échéant un filet progressant dans le sens horaire puis anti-horaire ou inversement.When the applicator member comprises a helical thread, it can progress in a clockwise and anti-clockwise direction toward the distal end. The application member may comprise, if necessary, a net progressing in the clockwise and then counter-clockwise direction or vice versa.

Sur la figure 25 on a illustré la possibilité pour l'organe d'application de comporter une partie métallique sur laquelle sont rapportées des touffes de poils 300.On the figure 25 the possibility has been illustrated for the applicator member to comprise a metal part on which tufts of bristles 300 are attached.

L'organe d'application 5 comporte par exemple des trous 301 dans lesquels sont insérées les touffes de poils 300, les poils étant retenus sur la partie métallique par exemple par matriçage de celle-ci.The applicator member 5 comprises, for example, holes 301 in which the tufts of bristles 300 are inserted, the bristles being retained on the metal part, for example by stamping it.

L'organe d'application 5 peut comporter en outre, comme illustré, si on le souhaite, des éléments d'application 100 métalliques, par exemple sur les cotés de l'organe d'application différents des faces par lesquelles les poils sortent. Les trous 301 recevant les touffes de poils peuvent être chacun d'axe perpendiculaire à un grand axe de la section transversale aplatie de la partie métallique de l'organe d'application, comme illustré à la figure 26.The application member 5 may further include, as illustrated, if desired, metal application elements 100, for example on the sides of the application member different faces by which the hairs come out. The holes 301 receiving the tufts of bristles may each be of axis perpendicular to a major axis of the flattened cross section of the metal part of the applicator member, as illustrated in FIG. figure 26 .

En variante, l'axe des trous peut être autre, par exemple oblique par rapport à ce grand axe.Alternatively, the axis of the holes may be other, for example oblique with respect to this major axis.

On a illustré aux figures 27 et 28 la possibilité de réaliser l'organe d'application 5 avec un logement 320, par exemple sous forme de trou traversant ou de fente traversante, ce logement étant rempli par une matière non métallique 325, par exemple une matière thermoplastique surmoulée sur la partie métallique. Les éléments d'application 149 peuvent être formés avec la partie non métallique, moulée sur la partie métallique. Ces éléments d'application 149 se présentent par exemple sous la forme de dents, qui sont par exemple disposées en rangée(s) sur un ou plusieurs cotés de l'organe d'application.We have illustrated Figures 27 and 28 the possibility of making the applicator member 5 with a housing 320, for example in the form of a through hole or through slot, this housing being filled with a non-metallic material 325, for example a thermoplastic material overmolded on the metal part. The application members 149 may be formed with the nonmetallic portion molded on the metal portion. These application elements 149 are for example in the form of teeth, which are for example arranged in a row (s) on one or more sides of the applicator member.

Sur la figure 31, on a représenté un organe d'application dans lequel le logement 320 se présente sous la forme d'une fente allongée parallèlement à l'axe longitudinal de l'organe d'application. D'un coté au moins de l'organe d'application est réalisé en matière thermoplastique au moins une rangée de dents 149, avec par exemple des dents disposées en quinconce.On the figure 31 there is shown an applicator member in which the housing 320 is in the form of an elongated slot parallel to the axis longitudinal axis of the application member. On at least one side of the applicator member is made of thermoplastic material at least one row of teeth 149, with for example teeth arranged in staggered rows.

On voit également sur cette figure que l'on peut réaliser la portion flexible 4b de la tige avec deux logements 333 et 334 à ses extrémités axiales, dans lesquels sont respectivement insérés la queue 110 de la partie métallique de l'organe d'application et un embout 338 réalisé avec la partie rigide de la tige. L'embout 338 et la queue 110 sont par exemple pourvus de reliefs destinés à améliorer l'ancrage au sein de la portion flexible 4b. Cette dernière peut être réalisée avec au moins une gorge 339, comme illustré, pour lui conférer plus de flexibilité.It can also be seen in this figure that the flexible portion 4b of the rod can be made with two housings 333 and 334 at its axial ends, in which are respectively inserted the shank 110 of the metal part of the applicator member and a tip 338 made with the rigid part of the rod. The tip 338 and the tail 110 are for example provided with reliefs for improving the anchoring within the flexible portion 4b. The latter can be made with at least one groove 339, as shown, to give it more flexibility.

Lorsque l'on réalise l'organe d'application 5 avec au moins une partie non métallique, la partie métallique peut comporter au moins un canal 341 qui peut servir à injecter à l'intérieur de la partie métallique de l'organe d'application la matière thermoplastique destinée à constituer la partie non métallique.When the applicator member 5 is made with at least one non-metallic part, the metal part may comprise at least one channel 341 that can be used to inject the inside of the metal part of the application member. the thermoplastic material intended to constitute the non-metallic part.

Ce canal 341 s'étend par exemple jusque dans la queue 110 de la partie métallique de l'organe d'application, voire peut la traverser en totalité, et peut déboucher par exemple, comme illustré à la figure 32, dans un logement 320, qui est par exemple une fente s'étendant longitudinalement sur la majeure partie de l'organe d'application.This channel 341 extends for example into the tail 110 of the metal part of the applicator member, or may pass through it in its entirety, and may open, for example, as illustrated in FIG. figure 32 in a housing 320, which is for example a slot extending longitudinally over the major part of the applicator member.

On a illustré sur la figure 29 la possibilité de réaliser l'organe d'application avec une partie servant à l'application qui est excentrée par rapport à l'axe longitudinal de la tige.We illustrated on the figure 29 the possibility of producing the applicator member with an application portion which is eccentric with respect to the longitudinal axis of the rod.

On a illustré à la figure 30 la possibilité de réaliser l'organe d'application avec une partie servant à l'application, qui présente deux cotés distincts où l'implantation des éléments en saillie est différente. Par exemple, l'un des cotés peut présenter des éléments en saillie très rapprochés tandis que l'autre coté peut présenter des éléments en saillie plus distants les uns des autres. La taille des éléments en saillie sur chacune des faces peut être différente. Les deux cotés sont par exemple situés à l'opposé l'un de l'autre.We illustrated at the figure 30 the possibility of producing the application member with a part for the application, which has two distinct sides where the implantation of the projecting elements is different. For example, one of the sides may have projecting elements very close together while the other side may have projecting elements further apart from each other. The size of the projecting elements on each of the faces may be different. The two sides are for example located opposite each other.

L'organe d'application peut être associé, le cas échéant, à une source de chaleur. L'organe d'application peut intégrer dans ce cas un élément chauffant, par exemple un fil résistif.The applicator member may be associated, where appropriate, with a heat source. In this case, the application member may incorporate a heating element, for example a resistive wire.

Dans tous les exemples ci-dessus, le métal peut être remplacé par un autre matériau inorganique, par exemple une céramique ou un verre.In all the above examples, the metal may be replaced by another inorganic material, for example a ceramic or a glass.

L'expression « comportant un » doit être comprise comme étant synonyme de « comportant au moins un », sauf si le contraire est spécifié.The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified.
