Description

La prƩsente invention concerne les applicateurs pour l'application d'un produit, notamment un produit cosmƩtique ou dermatologique.The present invention relates to applicators for the application of a product, in particular a cosmetic or dermatological product.

L'application d'une formulation cosmĆ©tique ou dermatologique pour usage topique se fait gĆ©nĆ©ralement directement avec le doigt. Toutefois, en appliquant le produit de cette maniĆØre, on est confrontĆ© au problĆØme d'hygiĆØne et de contamination du produit.The application of a cosmetic or dermatological formulation for topical use is usually done directly with the finger. However, applying the product in this way, one is confronted with the problem of hygiene and contamination of the product.

C'est pourquoi divers applicateurs cosmĆ©tiques ou mĆ©dicaux ont Ć©tĆ© proposĆ©s. Ils consistent gĆ©nĆ©ralement en un Ć©lĆ©ment d'application sur lequel est fixĆ© un support solide permettant de saisir l'applicateur. Les brevets US 6,371,132 , US 6,435,195 , US 4,053,242 , US 5,615,440 et US 6,009,887 dĆ©crivent par exemple de tels applicateurs. Dans certains cas, l'Ć©lĆ©ment d'application peut ĆŖtre prĆ©-imprĆ©gnĆ© du produit Ć  appliquer comme c'est le cas de l'applicateur dĆ©crit dans le brevet US 4,893,956 . Le document US 2001/036384 dĆ©crit un systĆØme permettant d'imprĆ©gner extemporanĆ©ment un support de type Ć©ponge par un liquide. Le systĆØme comporte un rĆ©servoir pour le liquide Ć  une extrĆ©mitĆ© duquel est fixĆ©e l'Ć©ponge. Lorsque l'on appuie sur le rĆ©servoir, l'intĆ©rieur du rĆ©servoir est mis en communication avec l'Ć©ponge. Pour appliquer le produit, le dispositif doit ĆŖtre saisi avec une main.This is why various cosmetic or medical applicators have been proposed. They generally consist of an application element on which is fixed a solid support for gripping the applicator. The US Patents 6,371,132 , US 6,435,195 , US 4,053,242 , US 5,615,440 and US 6,009,887 for example describe such applicators. In some cases, the application element may be pre-impregnated with the product to be applied, as is the case with the applicator described in FIG. U.S. Patent 4,893,956 . The document US 2001/036384 discloses a system for impregnating extemporaneously a sponge-type support with a liquid. The system includes a reservoir for the liquid at one end of which is fixed the sponge. When pressing the tank, the inside of the tank is put into communication with the sponge. To apply the product, the device must be grasped with one hand.

Ces dispositifs se rĆ©vĆØlent toutefois encombrants et ne permettent pas d'appliquer une dose de produit trĆØs prĆ©cise sur une zone d'application trĆØs bien dĆ©limitĆ©e. En outre, ces dispositifs limitent l'efficacitĆ© d'un massage tel qu'on peut l'obtenir avec le doigt.These devices are however bulky and do not allow to apply a dose of very precise product on a very well-defined application area. In addition, these devices limit the effectiveness of a massage that can be obtained with the finger.

Un systĆØme Ć  fixer sur le bout du doigt a Ć©tĆ© proposĆ© pour une utilisation dans l'hygiĆØne dentaire. Le brevet US 2,763,885 dĆ©crit un tel systĆØme constituĆ© d'une mousse abrasive imprĆ©gnĆ©e de dentifrice. Le brevet US 5,678,273 dĆ©crit un systĆØme similaire. Toutefois, les supports dĆ©crits ne sont pas adaptĆ©s Ć  l'application d'une prĆ©paration cosmĆ©tique ou mĆ©dicamenteuse.A fingertip system has been proposed for use in dental hygiene. The US Patent 2,763,885 describes such a system consisting of an abrasive foam impregnated with toothpaste. The US Patent 5,678,273 describes a similar system. However, the supports described are not suitable for the application of a cosmetic or medicinal preparation.

En outre, les systĆØmes prĆ©imprĆ©gnĆ©s de produit ne garantissent pas une bonne stabilitĆ© du produit.In addition, prepreg product systems do not guarantee good product stability.

Aussi, est-ce un des objets de l'invention que de rƩaliser un applicateur qui ne prƩsente pas les inconvƩnients de la technique antƩrieure.Also, is it an object of the invention to provide an applicator that does not have the disadvantages of the prior art.

C'est en particulier un objet de l'invention que de rƩaliser un applicateur peu encombrant qui permette l'application d'une dose de produit bien prƩcise sur une zone d'application bien dƩfinie.It is particularly an object of the invention to provide a compact applicator that allows the application of a specific dose of product on a well-defined application area.

C'est encore un autre objet de l'invention que de rƩaliser un applicateur qui permette de favoriser la pƩnƩtration du produit par massage.It is yet another object of the invention to provide an applicator which makes it possible to promote the penetration of the product by massage.

C'est Ʃgalement un autre objet de l'invention que de rƩaliser un applicateur garantissant l'absence de contamination extƩrieure du produit.It is also another object of the invention to provide an applicator ensuring the absence of external contamination of the product.

C'est aussi un autre objet de l'invention que de rĆ©aliser un tel applicateur prĆŖt Ć  l'emploi.It is also another object of the invention to provide such a ready-to-use applicator.

Selon l'invention, ces objets peuvent ĆŖtre atteints en rĆ©alisant un applicateur tel que revendiquĆ© dans la revendication 1.According to the invention, these objects can be achieved by making an applicator as claimed in claim 1.

Le produit contenu dans le rĆ©servoir pouvant ĆŖtre isolĆ© de la portion applicatrice, l'applicateur permet d'Ć©viter la contamination et les souillures du produit contenu dans le rĆ©servoir avant l'application. En outre, l'applicateur permet d'appliquer deux produits incompatibles entre eux, ou des produits instables au cours du temps par mĆ©lange extemporanĆ© lors de l'application, ou encore des produits qui produisent une rĆ©action exothermique lorsqu'ils sont mis en contact, l'un des produits Ć©tant conditionnĆ© dans le rĆ©servoir et l'autre dans la portion applicatrice.Since the product contained in the reservoir can be isolated from the applicator portion, the applicator makes it possible to prevent contamination and soiling of the product contained in the reservoir prior to application. In addition, the applicator makes it possible to apply two products that are incompatible with each other, or products that are unstable over time by extemporaneous mixing during application, or products that produce an exothermic reaction when they are brought into contact, one of the products being packaged in the reservoir and the other in the applicator portion.

II permet Ć©galement d'appliquer des produits trĆØs solubles dans l'eau qui ne peuvent ĆŖtre saisis directement avec les doigts du fait de leur sensibilitĆ© Ć  l'humiditĆ©.It also makes it possible to apply products that are very soluble in water and that can not be seized directly with the fingers because of their sensitivity to moisture.

Enfin, cet applicateur permet un maquillage Ā« au doigt Ā» relativement prĆ©cis sans toutefois toucher le produit.Finally, this applicator allows a "finger" makeup relatively accurate without touching the product.

Les moyens de fixation peuvent ĆŖtre constituĆ©s d'une couche adhĆ©sive formĆ©e du premier cĆ“tĆ© du rĆ©servoir, d'une bague, d'un doigt de gant, ou d'un systĆØme de type "velcro".The fixing means may consist of an adhesive layer formed on the first side of the reservoir, a ring, a thermowell, or a "velcro" type system.

Les moyens pour Ć©tablir la communication entre le rĆ©servoir et la portion applicatrice peuvent ĆŖtre constituĆ©s d'une membrane apte Ć  se rompre en rĆ©ponse Ć  une pression exercĆ©e du premier cĆ“tĆ© du rĆ©servoir, lors de la premiĆØre utilisation de l'applicateur.The means for establishing the communication between the reservoir and the applicator portion may consist of a membrane capable of breaking in response to a pressure exerted on the first side of the reservoir, during the first use of the applicator.

Alternativement ou en complĆ©ment, les moyens pour Ć©tablir la communication entre le rĆ©servoir et la portion applicatrice peuvent comporter un organe apte Ć  percer le second cĆ“tĆ© du rĆ©servoir. L'organe peut ĆŖtre formĆ© par exemple par un trocart solidaire du premier cĆ“tĆ© du rĆ©servoir.Alternatively or in addition, the means for establishing the communication between the reservoir and the applicator portion may comprise a member adapted to pierce the second side of the reservoir. The member may be formed for example by a trocar integral with the first side of the reservoir.

Selon un autre mode de rƩalisation, les moyens pour Ʃtablir la communication entre le rƩservoir et la portion applicatrice peuvent comporter au moins un clapet apte Ơ s'ouvrir en rƩponse Ơ une surpression gƩnƩrƩe Ơ l'intƩrieur du rƩservoir. La mise en communication entre le rƩservoir et la portion applicatrice est alors rƩversible.According to another embodiment, the means for establishing the communication between the reservoir and the applicator portion may comprise at least one valve capable of opening in response to an overpressure generated inside the reservoir. The communication between the reservoir and the applicator portion is then reversible.

Le premier cĆ“tĆ© du rĆ©servoir peut ĆŖtre configurĆ© de maniĆØre Ć  se dĆ©former en rĆ©ponse Ć  une pression extĆ©rieure de maniĆØre Ć  Ć©tablir la communication entre le rĆ©servoir et la portion applicatrice. En particulier, ce premier cĆ“tĆ© peut s'enfoncer vers l'intĆ©rieur du rĆ©servoir lorsque l'on appuie dessus avec un doigt. Ainsi, on peut rĆ©duire le volume intĆ©rieur du rĆ©servoir et gĆ©nĆ©rer une surpression Ć  l'intĆ©rieur du rĆ©servoir qui conduit Ć  la rupture de la membrane. Lorsque l'on enfonce le premier cĆ“tĆ© du rĆ©servoir, cela peut aussi entraĆ®ner le trocart en engagement avec la membrane de maniĆØre Ć  la percer.The first side of the reservoir may be configured to deform in response to an external pressure to establish communication between the reservoir and the applicator portion. In particular, this first side can sink into the tank when pressed with a finger. Thus, it is possible to reduce the internal volume of the tank and generate an overpressure inside the tank which leads to the rupture of the membrane. When the first side of the reservoir is pushed in, it can also cause the trocar to engage with the membrane to pierce it.

La portion applicatrice peut ĆŖtre rĆ©alisĆ©e en un matĆ©riau poreux ou fibreux, notamment en mousse d'un matĆ©riau thermoplastique, en Ć©ponge, en feutre, ou en fibres naturelles, notamment en coton.The applicator portion may be made of a porous or fibrous material, in particular foam of a thermoplastic material, sponge, felt, or natural fibers, especially cotton.

La portion applicatrice peut ĆŖtre rĆ©alisĆ©e en un matĆ©riau Ć©lastiquement dĆ©formable de maniĆØre Ć  obtenir une application relativement souple.The applicator portion may be made of an elastically deformable material so as to obtain a relatively flexible application.

La couche adhƩsive peut comporter un adhƩsif hypoallergƩnique.The adhesive layer may include a hypoallergenic adhesive.

L'applicateur peut prƩsenter, en coupe dans le sens de l'Ʃpaisseur, une forme convexe, au moins du cƓtƩ de la face servant Ơ l'application.The applicator may have, in cross-section in the direction of the thickness, a convex shape, at least on the side of the face serving the application.

L'applicateur peut prƩsenter, en coupe dans le sens de l'Ʃpaisseur, une forme concave du premier cƓtƩ du rƩservoir. Cette forme facilite le positionnement d'un doigt sur ce cƓtƩ.The applicator may have, in section in the direction of the thickness, a concave shape of the first side of the reservoir. This shape facilitates the positioning of a finger on this side.

Alternativement, l'applicateur peut prĆ©senter, en coupe dans le sens de l'Ć©paisseur, une forme aplatie avec un premier cĆ“tĆ© du rĆ©servoir sensiblement parallĆØle Ć  une face servant Ć  l'application.Alternatively, the applicator may have, in section in the direction of the thickness, a flattened shape with a first side of the reservoir substantially parallel to a face used for the application.

L'applicateur peut prƩsenter, en vue frontale, une forme circulaire ou encore une forme non circulaire, par exemple une forme gƩnƩralement triangulaire, carrƩe, ovale, de goutte d'eau ou encore d'amande.The applicator may have, in front view, a circular shape or a non-circular shape, for example a generally triangular shape, square, oval, drop of water or almond.

La premiĆØre paroi du rĆ©servoir recouverte d'adhĆ©sif peut ĆŖtre recouverte, avant la premiĆØre utilisation, d'une pellicule de protection amovible.The first wall of the tank covered with adhesive may be covered, before the first use, with a removable protective film.

Le produit contenu dans le rĆ©servoir peut ĆŖtre sous forme liquide, semi-liquide ou pĆ¢teuse.The product contained in the reservoir may be in liquid, semi-liquid or pasty form.

La portion applicatrice peut en outre contenir un second produit destinĆ© Ć  se mĆ©langer avec le produit contenu dans le rĆ©servoir, le second produit pouvant ĆŖtre sous forme liquide, semi-liquide, pĆ¢teuse ou sous forme de poudre.The applicator portion may further contain a second product for mixing with the product contained in the reservoir, the second product may be in liquid, semi-liquid, pasty or powder form.

Le rĆ©servoir peut dĆ©finir un volume sensiblement cylindrique, sphĆ©rique ou de toute autre forme. Le rĆ©servoir peut ĆŖtre rĆ©alisĆ© en polyĆ©thylĆØne, polypropylĆØne, PVC, polyamide, Ć©lastomĆØres thermoplastiques (SEBS), en poly-carbonates ou en TĆ©flon.The reservoir may define a substantially cylindrical, spherical or any other shape. The tank can be made of polyethylene, polypropylene, PVC, polyamide, thermoplastic elastomers (SEBS), polycarbonates or Teflon.

Les objets de l'invention peuvent Ć©galement ĆŖtre atteints en rĆ©alisant un dispositif de conditionnement et d'application comportant un logement fermĆ© contenant au moins un applicateur tel qu'il vient d'ĆŖtre dĆ©crit.The objects of the invention can also be achieved by providing a packaging and application device comprising a closed housing containing at least one applicator as just described.

Le dispositif peut ĆŖtre sous forme d'un sachet ou encore d'un alvĆ©ole fermĆ© par un film.The device may be in the form of a bag or a cell closed by a film.

L'applicateur selon l'invention est particuliĆØrement utile pour l'application d'un produit cosmĆ©tique ou dermatologique, notamment un produit dĆ©sinfectant, un filtre solaire, un produit hydratant, un anti-rides, un vernis Ć  ongles, un fond de teint, un rouge Ć  lĆØvres, un produit dĆ©maquillant, un produit de soin capillaire, un produit de coloration capillaire, un produit dĆ©odorant ou antitranspirant ou un parfum.The applicator according to the invention is particularly useful for the application of a cosmetic or dermatological product, in particular a disinfecting product, a sunscreen, a moisturizing product, an anti-wrinkle, a nail polish, a foundation, a lipstick, a makeup remover, a hair care product, a hair coloring product, a deodorant or antiperspirant product or a perfume.

L'applicateur 10 reprĆ©sentĆ© sur les figures 1 Ć  3 comporte un rĆ©servoir de produit 30 et une portion applicatrice 20 servant Ć  l'application d'un produit sur la peau, les muqueuses ou les phanĆØres.The applicator 10 shown on the Figures 1 to 3 comprises a product reservoir 30 and an applicator portion 20 for applying a product to the skin, mucous membranes or superficial body growths.

La portion applicatrice 20 peut comporter par exemple une couche d'un matƩriau poreux ou fibreux, notamment d'un matƩriau Ʃlastiquement dƩformable, tel qu'une mousse Ơ cellules ouvertes ou fermƩes, un feutre ou toutes autres structures alvƩolaires, notamment une Ʃponge naturelle ou non, ou des structures fibreuses notamment du coton ou du textile, ou une superposition de celles-ci.The applicator portion 20 may comprise, for example, a layer of a porous or fibrous material, in particular of an elastically deformable material, such as an open-cell or closed-cell foam, a felt or any other cellular structure, in particular a natural sponge or no, or fibrous structures including cotton or textile, or a superposition thereof.

La portion applicatrice peut Ć©galement comporter ou ĆŖtre constituĆ©e par un film, celui-ci pouvant ĆŖtre d'Ć©paisseur relativement faible.The applicator portion may also comprise or consist of a film, which may be of relatively small thickness.

La portion applicatrice 20 peut prƩsenter, en vue frontale, une forme circulaire et une Ʃpaisseur e sensiblement constante lui confƩrant une forme aplatie.The applicator portion 20 may present, in front view, a circular shape and a substantially constant thickness e giving it a flattened shape.

La portion applicatrice 20 dĆ©finit d'un cĆ“tĆ© une surface d'application 21 destinĆ©e Ć  ĆŖtre appliquĆ©e sur une zone Ć  traiter et, du cĆ“tĆ© opposĆ©, une face 22 collĆ©e Ć  sa pĆ©riphĆ©rie Ć  une membrane 41. Alternativement, la face 22 peut ĆŖtre en pĆ©riphĆ©rie thermosoudĆ©e sur la membrane 41.The applicator portion 20 defines on one side an application surface 21 intended to be applied to an area to be treated and, on the opposite side, a face 22 bonded at its periphery to a membrane 41. Alternatively, the face 22 may be periphery heat sealed to the membrane 41.

La membrane 41 constitue une paroi du rĆ©servoir 30 de produit, d'un cĆ“tĆ© 32 du rĆ©servoir, la membrane Ć©tant Ć©tanche au produit de maniĆØre Ć  isoler la portion applicatrice du produit contenu dans le rĆ©servoir. La membrane 41 peut ĆŖtre rĆ©alisĆ©e par exemple en polyĆ©thylĆØne, en polypropylĆØne, PVC, polyamide, Ć©lastomĆØres thermoplastiques (SEBS), en poly-carbonates ou en polyurĆ©thane.The membrane 41 constitutes a wall of the product reservoir 30, on one side 32 of the reservoir, the membrane being tight to the product so as to isolate the applicator portion of the product contained in the reservoir. The membrane 41 may be made for example of polyethylene, polypropylene, PVC, polyamide, thermoplastic elastomers (SEBS), polycarbonates or polyurethane.

Le rĆ©servoir 30 comporte une paroi latĆ©rale 33 de section circulaire sur le bord libre de laquelle est collĆ©e ou thermosoudĆ©e la membrane 41. La paroi latĆ©rale est par exemple rĆ©alisĆ©e en matiĆØre plastique notamment en polyĆ©thylĆØne, polypropylĆØne, PVC, polyamide, Ć©lastomĆØres thermoplastiques (SEBS) ou en poly-carbonates. On choisira une Ć©paisseur suffisante pour que cette paroi latĆ©rale soit relativement rigide.The tank 30 has a lateral wall 33 of circular section on the free edge of which is glued or heat sealed membrane 41. The side wall is for example made of plastic material including polyethylene, polypropylene, PVC, polyamide, thermoplastic elastomers (SEBS) or in polycarbonates. We choose a sufficient thickness for this side wall is relatively rigid.

Du cĆ“tĆ© opposĆ© au cĆ“tĆ© 32 du rĆ©servoir, la paroi latĆ©rale 33 du rĆ©servoir est fermĆ©e par une paroi 31 lĆ©gĆØrement concave. La paroi 31 est relativement fine, elle est par exemple comprise entre 200 Āµm et 2000 Āµm, et de prĆ©fĆ©rence entre 500 Āµm et 1000 Āµm de sorte qu'elle peut se dĆ©former en rĆ©ponse Ć  une pression exercĆ©e par un doigt.On the side opposite the side 32 of the tank, the side wall 33 of the tank is closed by a slightly concave wall 31. The wall 31 is relatively thin, it is for example between 200 microns and 2000 microns, and preferably between 500 microns and 1000 microns so that it can be deformed in response to a pressure exerted by a finger.

La paroi 31 est recouverte, sur sa face opposĆ©e Ć  l'intĆ©rieur du rĆ©servoir, d'une couche d'adhĆ©sif 310. L'adhĆ©sif peut ĆŖtre un adhĆ©sif permanent, rĆ©sistant Ć  l'eau, hypoallergĆ©nique, qui adhĆØre plus fortement Ć  la paroi 31 qu'Ć  la peau. La couche d'adhĆ©sif 310 peut ĆŖtre prĆ©sente sous la forme d'un film, lequel peut couvrir entiĆØrement la face de la paroi 31. La couche d'adhĆ©sif peut encore ĆŖtre prĆ©sente sous la forme d'un rĆ©seau de points, d'une sĆ©rie de bandes, ou ne s'Ć©tendre que dans la rĆ©gion centrale de la paroi 31. La couche d'adhĆ©sif peut encore ĆŖtre recouverte, par exemple, par un filet permettant d'en diminuer le pouvoir adhĆ©sif.The wall 31 is covered, on its face opposite to the inside of the tank, with an adhesive layer 310. The adhesive may be a permanent, water-resistant, hypoallergenic adhesive which adheres more strongly to the wall 31 only to the skin. The adhesive layer 310 may be present in the form of a film, which may completely cover the face of the wall 31. The adhesive layer may also be present in the form of a network of dots, a series of strips, or extend only in the central region of the wall 31. The layer of adhesive can still be covered, for example, by a net to reduce the adhesive power.

La couche d'adhĆ©sif 310 peut ĆŖtre recouverte, avant la premiĆØre utilisation, par une pellicule de protection amovible 50 pouvant comporter une languette 51 dĆ©bordant la paroi latĆ©rale 33 du rĆ©servoir 30 pour faciliter son retrait. La pellicule de protection 50 comporte par exemple un papier siliconĆ© ou un film de polyĆ©thylĆØne.The adhesive layer 310 may be covered, before the first use, by a removable protective film 50 may include a tab 51 projecting from the side wall 33 of the reservoir 30 to facilitate its removal. The protective film 50 comprises for example a silicone paper or a polyethylene film.

Le rĆ©servoir 30 contient un produit P liquide, semi-liquide ou pĆ¢teuse, sous la forme d'une prĆ©paration cosmĆ©tique ou dermatologique.The reservoir 30 contains a liquid product P, semi-liquid or pasty, in the form of a cosmetic or dermatological preparation.

La portion applicatrice 20 peut Ć©galement ĆŖtre prĆ©imprĆ©gnĆ©e d'un second produit, Ć©galement sous forme liquide, semi-liquide ou pĆ¢teuse, ou encore sous forme de poudre. Cela permet notamment d'appliquer deux prĆ©parations incompatibles entre elles ou des prĆ©parations instables au cours du temps par mĆ©lange extemporanĆ© lors de l'application.The applicator portion 20 may also be pre-impregnated with a second product, also in liquid, semi-liquid or pasty form, or in powder form. This allows in particular to apply two incompatible preparations or unstable preparations over time by extemporaneous mixing during application.

Pour utiliser l'applicateur 10, l'utilisateur retire la pellicule de protection amovible 50 et pose un doigt sur la face de la paroi 31 recouverte d'adhĆ©sif. L'applicateur 10 est ainsi fixĆ© sur la pulpe de la premiĆØre phalangette de l'index par exemple, comme on le voit Ć  la figure 2. La surface d'application 21 est alors appliquĆ©e sur la partie du corps devant recevoir la prĆ©paration. Lors de cette application, la paroi 31 se dĆ©forme vers l'intĆ©rieur du rĆ©servoir rĆ©duisant ainsi le volume de celui-ci. Une surpression est ainsi crĆ©Ć©e Ć  l'intĆ©rieur du rĆ©servoir, la surpression Ć©tant telle que la membrane 41 se dĆ©chire et forme un passage 34 illustrĆ© Ć  la figure 3. Le produit P peut alors s'Ć©couler dans la portion applicatrice 20 par le passage 34. Le produit se dĆ©place, soit simplement par gravitĆ©, soit Ć©galement par capillaritĆ© dans les pores ou entre les fibres du matĆ©riau poreux ou fibreux constituant la portion applicatrice 20, jusqu'Ć  la surface d'application 21. Le produit peut Ć©galement se dĆ©placer vers la portion applicatrice par pompage du matĆ©riau constituant la portion applicatrice lorsque celui-ci est Ć©lastiquement dĆ©formable. On peut alors Ć©taler le produit sur une zone bien prĆ©cise et/ou masser la zone.To use the applicator 10, the user removes the removable protective film 50 and places a finger on the face of the wall 31 covered with adhesive. The applicator 10 is thus fixed on the pulp of the first phalanget of the index for example, as seen in FIG. figure 2 . The application surface 21 is then applied to the part of the body to receive the preparation. During this application, the wall 31 deforms towards the inside of the tank thus reducing the volume thereof. An overpressure is thus created inside the tank, the overpressure being such that the membrane 41 tears and forms a passage 34 illustrated in FIG. figure 3 . The product P can then flow into the applicator portion 20 through the passage 34. The product moves, either simply by gravity, or also by capillarity in the pores or between the fibers of the porous or fibrous material constituting the applicator portion 20. to the application surface 21. The product can also move to the applicator portion by pumping the material constituting the applicator portion when it is elastically deformable. We can then spread the product on a specific area and / or massage the area.

L'applicateur 10 peut par exemple ĆŖtre utilisĆ© pour l'application sur la patte d'oie ou la zone situĆ©e au-dessus de la lĆØvre supĆ©rieure de prĆ©parations anti-rides Ć  base de vitamine C et/ou de rĆ©tinol. De faƧon similaire, il peut ĆŖtre utilisĆ© pour l'application de prĆ©parations anti-virales sur une lĆ©sion labiale herpĆ©tique.The applicator 10 may for example be used for application on the crow's feet or the area above the upper lip of anti-wrinkle preparations based on vitamin C and / or retinol. Similarly, it can be used for the application of anti-viral preparations on a herpetic labial lesion.

Toujours Ć  titre d'exemple, l'applicateur peut Ć©galement ĆŖtre utilisĆ© pour appliquer des ombres Ć  paupiĆØres ou des rouges Ć  lĆØvre. Il permet Ć©galement des retouches de parfum, le dĆ©maquillage des ongles ou la rĆ©alisation de micropeeling sur le visage.Still as an example, the applicator can also be used to apply eye shadows or lipsticks. It also allows perfume retouching, removal of nails or micropeeling on the face.

L'applicateur 10 peut, bien entendu, prĆ©senter une forme diffĆ©rente de celle qui vient d'ĆŖtre dĆ©crite, adaptĆ©e notamment Ć  la zone du corps ou du visage sur laquelle on souhaite l'appliquer.The applicator 10 may, of course, have a shape different from that just described, particularly adapted to the area of the body or face on which it is desired to apply it.

L'applicateur 10 peut par exemple prƩsenter une surface d'application 21 bombƩe, par exemple convexe vers l'extƩrieur, comme illustrƩ Ơ la figure 4. Dans cet exemple, la surface d'application 21 est recouverte d'un film de non-tissƩ 23.The applicator 10 may for example have a convex application surface 21 convex, for example convex towards the outside, as illustrated in FIG. figure 4 . In this example, the application surface 21 is covered with a nonwoven film 23.

Dans l'exemple reprƩsentƩ Ơ la figure 5, la surface d'application 21 comporte un flocage 24. Dans cet exemple, la paroi 31 est plane et non concave.In the example shown in figure 5 , the application surface 21 comprises a flocking 24. In this example, the wall 31 is flat and not concave.

L'applicateur 10 peut prĆ©senter, lorsque observĆ© en vue frontale, une forme autre que circulaire, afin de permettre par exemple d'appliquer plus facilement ou plus prĆ©cisĆ©ment un produit sur une partie donnĆ©e du visage, par exemple les paupiĆØres ou les lĆØvres.The applicator 10 may have, when viewed in front view, a shape other than circular, to allow for example to more easily or more accurately apply a product on a given part of the face, for example the eyelids or lips.

On a reprƩsentƩ sur les figures 6A Ơ 6E, en vue frontale, diffƩrents exemples, parmi d'autres, de formes possibles. L'applicateur 10 peut prƩsenter, en vue frontale, une forme sensiblement carrƩe (figure 6A), ovale (figure 6B), triangulaire (figure 6C), en forme d'amande (figure 6D) ou encore en forme de goutte d'eau (figure 6E).We have shown on Figures 6A to 6E in frontal view, various examples, among others, of possible forms. The applicator 10 may have, in front view, a substantially square shape ( Figure 6A ), oval ( Figure 6B ), triangular ( Figure 6C ), almond-shaped ( Figure 6D ) or in the form of a drop of water ( figure 6E ).

Selon une variante non reprĆ©sentĆ©e, la portion applicatrice 20 peut contenir ou ĆŖtre formĆ©e par un film fin polymĆ©rique. Ce film peut par exemple contenir une prĆ©paration Ć  appliquer, qui sera solubilisĆ©e extemporanĆ©ment par une solution aqueuse contenue dans le rĆ©servoir.According to a variant not shown, the applicator portion 20 may contain or be formed by a thin polymeric film. This film may for example contain a preparation to be applied, which will be solubilized extemporaneously by an aqueous solution contained in the reservoir.

On peut, sans sortir du cadre de la prĆ©sente invention, disposer un applicateur 10 sur les extrĆ©mitĆ©s de deux doigts rĆ©unis, comme illustrĆ© Ć  la figure 7, ou deux applicateurs ayant par exemple des formes diffĆ©rentes Ć  l'extrĆ©mitĆ© d'un doigt, comme illustrĆ© Ć  la figure 8. A titre d'exemple, deux applicateurs apposĆ©s sur deux doigts opposables peuvent ĆŖtre utilisĆ©s pour rĆ©aliser une pince et dĆ©maquiller les cils ou colorer une mĆØche de cheveu. Dans le cas du soin des cils, une telle utilisation de deux applicateurs permet d'Ć©viter les aurĆ©oles sous les yeux et de ne souiller ni l'oeil, ni la paupiĆØre. Une telle utilisation de deux ou plusieurs applicateurs, permet Ć©galement de manier avec facilitĆ© plusieurs produits Ć  la fois de faƧon, par exemple, Ć  rĆ©aliser un maquillage crĆ©atif multicolore.Without departing from the scope of the present invention, an applicator 10 may be placed on the ends of two joined fingers, as illustrated in FIG. figure 7 , or two applicators having for example different shapes at the end of a finger, as illustrated in FIG. figure 8 . For example, two applicators affixed to two opposable fingers can be used to make a clip and make-up lashes or color a lock of hair. In the case of care of the eyelashes, such a use of two applicators makes it possible to avoid the halos under the eyes and to not contaminate the eye or the eyelid. Such use of two or more applicators, also makes it easy to handle several products at once so, for example, to achieve a multicolored creative makeup.

L'applicateur 10 peut ĆŖtre conditionnĆ© par exemple dans un sachet. Alternativement, l'applicateur 10 peut ĆŖtre logĆ© dans un alvĆ©ole 60, formĆ© par exemple par thermoformage d'une plaque de matĆ©riau thermoplastique, comme on l'a reprĆ©sentĆ© Ć  la figure 9. L'alvĆ©ole dĆ©finit un logement 61 dans lequel est logĆ© l'applicateur 10, la pellicule de protection amovible 50 est alors fixĆ©e Ć  l'alvĆ©ole autour du logement, par exemple par thermosoudage 52, de maniĆØre Ć  fermer le logement 61 de maniĆØre Ć©tanche. Il est bien Ć©vident que chaque logement peut loger plusieurs applicateurs 10.The applicator 10 may be packaged for example in a sachet. Alternatively, the applicator 10 may be housed in a cell 60, formed for example by thermoforming a plate of thermoplastic material, as shown in FIG. figure 9 . The cell defines a housing 61 in which is housed the applicator 10, the removable protective film 50 is then fixed to the cell around the housing, for example by heat sealing 52, so as to close the housing 61 in a sealed manner. It is obvious that each housing can accommodate several applicators 10.

L'alvƩole peut Ʃgalement dƩlimiter plusieurs logements 61 logeant chacun un ou plusieurs applicateur(s) 10, comme on l'a illustrƩ Ơ la figure 10. Des lignes de prƩdƩcoupe 62 sont disposƩes autour de chaque logement pour permettre de sƩparer chaque logement muni de son applicateur et fermƩ par la pellicule de protection amovible 50.The cell may also delimit several housings 61 each housing one or more applicator (s) 10, as illustrated in FIG. figure 10 . Pre-cut lines 62 are arranged around each housing to allow separation of each housing provided with its applicator and closed by the removable protective film 50.

Selon un autre mode de rĆ©alisation reprĆ©sentĆ© sur les figures 11 et 12, l'applicateur 10 peut en outre comporter des moyens aptes Ć  percer la membrane 41 isolant la portion applicatrice 20 du produit contenu dans le rĆ©servoir 30. Il s'agit par exemple d'un trocart 42 formĆ© Ć  partir de la paroi 31 et dont l'extrĆ©mitĆ© libre coupante 420 est orientĆ©e vers la membrane 41. Comme on l'a illustrĆ© Ć  la figure 11, l'extrĆ©mitĆ© libre coupante 420 du trocart est Ć  distance de la membrane 41 lorsque la paroi 31 n'est pas dĆ©formĆ©e. Lorsque l'utilisateur colle son doigt sur la paroi 31 et qu'il applique la surface d'application 21 sur la zone Ć  traiter, la paroi 31 se dĆ©forme vers l'intĆ©rieur du rĆ©servoir et dĆ©place le trocart 42 jusqu'Ć  la membrane 41. L'extrĆ©mitĆ© coupante 420 du trocart perce alors la membrane 41 de maniĆØre Ć  former un passage 34 pour le produit, comme on l'a illustrĆ© Ć  la figure 12.According to another embodiment shown on the Figures 11 and 12 , the applicator 10 may further comprise means capable of piercing the membrane 41 insulating the applicator portion 20 of the product contained in the reservoir 30. This is for example a trocar 42 formed from the wall 31 and whose free cutting end 420 is oriented towards the membrane 41. As one illustrated it at the figure 11 , the free cutting end 420 of the trocar is at a distance from the membrane 41 when the wall 31 is not deformed. When the user sticks his finger on the wall 31 and applies the application surface 21 to the area to be treated, the wall 31 deforms towards the inside of the tank and moves the trocar 42 to the membrane 41 The cutting end 420 of the trocar then pierces the membrane 41 so as to form a passage 34 for the product, as illustrated in FIG. figure 12 .

Les moyens de fixation de l'applicateur sur un ou plusieurs doigts peuvent ĆŖtre diffĆ©rents d'une couche adhĆ©sive comme celle qui vient d'ĆŖtre dĆ©crite. A titre d'exemple, on a reprĆ©sentĆ© sur les figures 13 Ć  15 diffĆ©rents exemples de moyens pour fixer de faƧon rĆ©versible l'applicateur sur un doigt.The fixing means of the applicator on one or more fingers may be different from an adhesive layer such as that just described. For example, there is shown on the Figures 13 to 15 various examples of means for reversibly fixing the applicator on a finger.

A la figure 13, l'applicateur 10 est par exemple fixĆ© au doigt par une bague 311. L'applicateur peut Ć©galement ĆŖtre fixĆ© au doigt par un doigt de gant 312 comme on l'a reprĆ©sentĆ© Ć  la figure 14. Dans ces deux modes de rĆ©alisation, la bague et le doigt de gants peuvent ĆŖtre solidaires du cĆ“tĆ© 31 du rĆ©servoir 30. Alternativement, on peut utiliser un systĆØme de type "velcro" 313, reprĆ©sentĆ© sur la figure 15, pour solidariser une bague ou un doigt de gant sur le cĆ“tĆ© 31 du rĆ©servoir afin de fixer l'applicateur 10 sur un doigt.To the figure 13 , the applicator 10 is for example fixed to the finger by a ring 311. The applicator may also be attached to the finger by a finger of glove 312 as shown in FIG. figure 14 . In these two embodiments, the ring and the glove finger can be integral with the side 31 of the tank 30. Alternatively, a "velcro" type system 313, shown in FIG. figure 15 , to secure a ring or a thermowell on the side 31 of the reservoir to fix the applicator 10 on a finger.

On va maintenant dĆ©crire, Ć  titre purement illustratif, des exemples particuliers d'un applicateur selon l'invention pour des applications particuliĆØres.Specific examples of an applicator according to the invention for particular applications will now be described, purely by way of illustration.

EXEMPLE 1EXAMPLE 1

L'applicateur 10 peut ĆŖtre utilisĆ© pour appliquer une crĆØme de soin Ć  base d'acide salicylique. Selon cet exemple, la portion applicatrice 20 est rĆ©alisĆ©e en mousse de polyurĆ©thane. La face 22 de la portion applicatrice est collĆ©e, Ć  sa pĆ©riphĆ©rie, par un adhĆ©sif acrylique, Ć  une membrane 41 en polyĆ©thylĆØne. Les parois latĆ©rales 33 et la paroi 31 du rĆ©servoir 30 sont rĆ©alisĆ©es en polyĆ©thylĆØne basse densitĆ©. Le rĆ©servoir 30 contient 0,2 ml d'une crĆØme de soin Ć  1% d'acide salicylique. Enfin, la paroi 33 du rĆ©cipient est recouverte d'un adhĆ©sif silicone.The applicator 10 can be used to apply a salicylic acid care cream. According to this example, the applicator portion 20 is made of polyurethane foam. The face 22 of the applicator portion is bonded at its periphery, by an acrylic adhesive, to a membrane 41 of polyethylene. The side walls 33 and the wall 31 of the tank 30 are made of polyethylene low density. The reservoir 30 contains 0.2 ml of a 1% salicylic acid care cream. Finally, the wall 33 of the container is covered with a silicone adhesive.

EXEMPLE 2EXAMPLE 2

L'applicateur 10 peut ĆŖtre utilisĆ© pour appliquer une dose exacte de vitamine C pure. Selon cet exemple, la portion applicatrice 20 est une Ć©ponge. L'Ć©ponge est imprĆ©gnĆ©e de vitamine C pure sous forme de poudre. La face 22 de la portion applicatrice est collĆ©e, Ć  sa pĆ©riphĆ©rie, par un adhĆ©sif acrylique, Ć  une membrane 41 en polyĆ©thylĆØne. Les parois latĆ©rales 33 et la paroi 31 du rĆ©servoir 30 sont rĆ©alisĆ©es en polypropylĆØne. Le rĆ©servoir 30 contient cette fois 0,2 ml d'eau thermale. Enfin, la paroi 31 du rĆ©cipient est recouverte d'un adhĆ©sif silicone. Au moment de l'application, l'eau thermale vient imprĆ©gner l'Ć©ponge, solubiliser la vitamine C et permettre son action au niveau de la peau. Un tel applicateur permet de maintenir l'intĆ©gritĆ© de la vitamine C, instable en solution, comparativement Ć  une forme solubilisĆ©e, la vitamine C Ć©tant non dĆ©gradĆ©e et active.The applicator 10 can be used to apply an exact dose of pure vitamin C. According to this example, the applicator portion 20 is a sponge. The sponge is impregnated with pure vitamin C in powder form. The face 22 of the applicator portion is bonded at its periphery, by an acrylic adhesive, to a membrane 41 of polyethylene. The side walls 33 and the wall 31 of the tank 30 are made of polypropylene. The reservoir 30 this time contains 0.2 ml of thermal water. Finally, the wall 31 of the container is covered with a silicone adhesive. At the time of application, the thermal water comes impregnate the sponge, solubilize vitamin C and allow its action on the skin. Such an applicator makes it possible to maintain the integrity of vitamin C, which is unstable in solution, compared to a solubilized form, vitamin C being non-degraded and active.
