Abstract

The applicator consists of a housing (1) which acts as a reservoir (3) for the product and contains an applicator brush (7) which can move between extended and retracted positions. A second section (2) of the housing is closed by a stopper (5) on the inside of a screw cap to prevent the viscous product from escaping. A cylindrical partition (17) is impermeable to the cosmetic product but allows the solvent contained in it to pass through, preventing the product from drying out or increasing in viscosity. The partition, which surrounds the brush (7) when it is in its retracted position, is made from a porous material, produced e.g. by fitting or agglomeration of fibres, or it can have a solid wall with narrow capillary slits or holes of very small diameter.

Description

La présente invention est relative à un applicateur pour produits cosmétiques visqueux en particulier pour vernis à ongles.The present invention relates to an applicator for viscous cosmetic products, in particular for nail polish.

On utilise, notamment pour les vernis à ongles, des produits cosmétiques visqueux qui sont généralement appliqués avec des pinceaux.Viscous cosmetic products are used, in particular for nail varnishes, which are generally applied with brushes.

De tels applicateurs sont le plus souvent constitués par un flacon qui contient le produit cosmétique et dont le bouchon est muni d'un pinceau ou d'un autre organe applicateur qui, à l'état fermé, pénètre dans le flacon et se trouve en contact avec le produit cosmétique du flacon ce qui évite l'épaississement du produit cosmétique qui est demeuré sur le pinceau à la suite de l'application précédente.Such applicators are most often constituted by a bottle which contains the cosmetic product and the cap of which is provided with a brush or another applicator member which, in the closed state, penetrates into the bottle and is in contact with the cosmetic product in the bottle, which prevents thickening of the cosmetic product which remained on the brush following the previous application.

On sait en effet que de tels produits cosmétiques sont généralement constitués par des composés, colorés ou non, incorporés à des solvants de diverses natures éventuellement aqueux qui par leur évaporation provoquent le séchage et le durcissement du produit cosmétique.It is known in fact that such cosmetic products generally consist of compounds, colored or not, incorporated into solvents of various natures, possibly aqueous, which by their evaporation cause the drying and hardening of the cosmetic product.

Les applicateurs de ce type sont d'une grande simplicité mais ils présentent l'inconvénient que, lors de leur utilisation, il existe un risque non négligeable de voir le flacon ouvert se renverser en laissant s'écouler le produit cosmétique qui endommage les vêtements de l'utilisateur ou les objets qui se trouvent à proximité.Applicators of this type are very simple, but they have the disadvantage that, during their use, there is a non-negligible risk of seeing the open bottle overturn, letting the cosmetic product run off, which damages the clothes of the user or objects nearby.

Pour éviter cet inconvénient, on a déjà proposé des applicateurs de type "stylo" qui sont constitués par un corps formant réservoir pour la composition cosmétique, par un organe applicateur tel qu'un pinceau solidaire du corps et par un bouchon dont le seul rôle est d'obturer le corps.To avoid this drawback, applicators of the “pen” type have already been proposed which are constituted by a body forming a reservoir for the cosmetic composition, by an applicator member such as a brush secured to the body and by a plug whose sole role is shut off the body.

Dans cet autre type d'applicateur connu, l'organe applicateur est susceptible d'être déplacé, généralement par gravité, entre deux positions, à savoir une position sortie dans laquelle le bouchon est séparé du corps de l'applicateur, et une position rentrée dans laquelle l'organe applicateur est totalement contenu dans le corps de l'applicateur, le bouchon obturant le corps de l'applicateur et évitant que le produit cosmétique se répande à l'extérieur.In this other known type of applicator, the applicator member is capable of being moved, generally by gravity, between two positions, namely an extended position in which the plug is separated from the body of the applicator, and a retracted position wherein the applicator member is completely contained in the body of the applicator, the plug sealing the body of the applicator and preventing the cosmetic product from spreading outside.

Ce second type d'applicateur facilite l'utilisation du produit cosmétique mais présente l'inconvénient que, lors de la fermeture du bouchon, l'organe applicateur est rentré à l'intérieur du corps avec une quantité non négligeable de produit cosmétique qui a déjà commencé à sécher et qui continue à le faire alors que le bouchon est déjà appliqué sur le corps de l'applicateur en raison de l'évaporation du solvant dans le volume fermé qui entoure l'organe applicateur.This second type of applicator facilitates the use of the cosmetic product but has the drawback that, when closing of the cap, the applicator member has returned to the interior of the body with a non-negligible amount of cosmetic product which has already started to dry and which continues to do so while the cap is already applied to the body of the applicator. due to the evaporation of the solvent in the closed volume which surrounds the applicator member.

Il se produit ainsi progressivement un dépôt de produit cosmétique solidifié ou fortement visqueux sur l'organe applicateur et dans la partie du corps de l'applicateur qui l'entoure, ce qui conduit à une utilisation de plus en plus difficile du produit cosmétique et à la perte d'une partie de ce dernier.There is thus gradually a deposit of solidified or highly viscous cosmetic product on the applicator member and in the part of the body of the applicator which surrounds it, which leads to an increasingly difficult use of the cosmetic product and to the loss of part of it.

La présente invention a pour but de réaliser un applicateur du type dans lequel l'organe applicateur est solidaire du corps de l'applicateur qui contient le produit cosmétique, qui permette d'éviter un dépôt de produit cosmétique solidifié ou tout au moins de viscosité élevée sur et autour de l'organe applicateur.The object of the present invention is to produce an applicator of the type in which the applicator member is integral with the body of the applicator which contains the cosmetic product, which makes it possible to avoid a deposit of solidified cosmetic product or at least of high viscosity. on and around the applicator member.

Conformément à l'invention, ce résultat peut être obtenu par l'utilisation de moyens simples, efficaces et peu coûteux.According to the invention, this result can be obtained by the use of simple, effective and inexpensive means.

La présente invention a pour objet un applicateur de produit cosmétique visqueux tel qu'un vernis à ongles, du type comportant un corps d'applicateur constituant un réservoir pour le produit cosmétique, ce corps contenant un organe applicateur susceptible d'être déplacé entre une position de fermeture dans laquelle l'organe applicateur est complètement engagé à l'intérieur du corps et une position d'ouverture dans laquelle l'organe applicateur fait saillie hors du corps, le corps de l'applicateur étant obturé par un bouchon lorsque l'organe applicateur est en position de fermeture, ledit applicateur étant caractérisé par le fait qu'à l'état fermé, un obturateur empêche que le produit cosmétique contenu dans la partie du corps de l'applicateur qui constitue le réservoir pour le produit cosmétique, puisse, compte-tenu de sa viscosité, s'écouler vers la partie du corps de l'applicateur qui est obturée par le bouchon et qui contient l'organe applicateur ; et que la partie du corps de l'applicateur qui contient le produit cosmétique est reliée à la partie du corps de l'applicateur qui est obturé par le bouchon et qui contient l'organe applicateur, par une paroi qui empêche l'écoulement du produit cosmétique mais qui laisse passer le solvant contenu dans le produit cosmétique, de telle sorte qu'en position fermée, ce solvant puisse se répandre dans le volume entourant l'organe applicateur en s'opposant au durcissement ou à l'accroissement de la viscosité du produit cosmétique qui est présent sur l'organe applicateur, sur sa tige ou sur les parois du volume qui l'entourent.The present invention relates to an applicator of viscous cosmetic product such as a nail varnish, of the type comprising an applicator body constituting a reservoir for the cosmetic product, this body containing an applicator member capable of being moved between a position closure in which the applicator member is completely engaged inside the body and an open position in which the applicator member projects out of the body, the body of the applicator being closed by a plug when the member applicator is in the closed position, said applicator being characterized in that in the closed state, a shutter prevents the cosmetic product contained in the part of the body of the applicator which constitutes the reservoir for the cosmetic product, from being able to, taking into account its viscosity, flow towards the part of the body of the applicator which is closed by the cap and which contains the applicator member; and that the part of the body of the applicator which contains the cosmetic product is connected to the part of the body of the applicator which is closed by the cap and which contains the applicator member, by a wall which prevents the flow of the product cosmetic but which allows the solvent contained in the cosmetic product to pass through, so that in the closed position, this solvent can spread in the volume surrounding the applicator member by opposing the hardening or the increase in the viscosity of the cosmetic product which is present on the applicator member, on its stem or on the walls of the volume which l 'surround.

Conformément à un mode préféré de l'invention, la paroi qui permet au solvant de pénétrer dans le volume qui contient l'organe applicateur est un corps de forme générale tubulaire constitué par une matière poreuse obtenue par exemple par frittage, dont une partie peut avantageusement servir à former avec l'organe applicateur, l'obturateur entre la partie du corps de l'applicateur qui contient le produit cosmétique et la partie de ce corps qui, à l'état fermé, contient l'organe applicateur.In accordance with a preferred embodiment of the invention, the wall which allows the solvent to enter the volume which contains the applicator member is a body of generally tubular shape consisting of a porous material obtained for example by sintering, a part of which can advantageously serve to form with the applicator organ, the obturator between the part of the body of the applicator which contains the cosmetic product and the part of this body which, in the closed state, contains the applicator organ.

Il en résulte que cette paroi poreuse est au contact par une de ses faces avec le produit cosmétique ou avec les vapeurs du solvant de ce dernier qui sont à l'intérieur du corps de l'applicateur, ledit solvant migrant à travers de la paroi poreuse pour parvenir dans la partie du corps de l'applicateur qui entoure l'organe applicateur.As a result, this porous wall is in contact by one of its faces with the cosmetic product or with the solvent vapors of the latter which are inside the body of the applicator, said solvent migrating through the porous wall to reach the part of the body of the applicator which surrounds the applicator member.

Lors du remplissage de l'applicateur avec le produit cosmétique, il peut être avantageux de saturer la paroi poreuse avec le solvant qui est utilisé dans le produit cosmétique.When filling the applicator with the cosmetic product, it may be advantageous to saturate the porous wall with the solvent which is used in the cosmetic product.

Dans une variante, au lieu d'une paroi poreuse, il est possible d'utiliser une paroi de forme générale cylindrique ou tronconique qui entoure l'organe applicateur et qui est munie de fentes de très faible largeur ou de trous de très faible diamètre qui par capillarité empêchent le passage du produit cosmétique tout en permettant le passage du solvant.Alternatively, instead of a porous wall, it is possible to use a wall of generally cylindrical or frustoconical shape which surrounds the applicator member and which is provided with very narrow slots or very small diameter holes which by capillary action prevent the passage of the cosmetic product while allowing the passage of the solvent.

Dans ce mode de réalisation, le volume extérieur à la paroi munie de fentes est relié à la partie du corps de l'applicateur qui contient le produit cosmétique.In this embodiment, the volume outside the wall provided with slots is connected to the part of the body of the applicator which contains the cosmetic product.

Selon un mode de réalisation préféré de l'invention, l'obturateur qui empêche le produit cosmétique contenu dans la partie arrière du corps de l'applicateur de passer dans la partie avant du corps de l'applicateur qui entoure l'organe applicateur, est constitué par une surépaisseur située à la base de l'organe applicateur, qui coopère avec la paroi poreuse ou capillaire qui vient d'être décrite, de manière à ce que, compte-tenu de sa viscosité, le produit cosmétique ne puisse pas s'écouler de la partie du corps de l'applicateur où il est contenu, vers la partie du corps de l'applicateur qui entoure l'organe applicateur.According to a preferred embodiment of the invention, the shutter which prevents the cosmetic product contained in the rear part of the body of the applicator from passing into the front part of the body of the applicator which surrounds the applicator member, is constituted by an extra thickness situated at the base of the applicator member, which cooperates with the porous or capillary wall which has just been described, so that, taking into account its viscosity, the cosmetic product cannot flow from the part of the body of the applicator where it is contained, towards the part of the body of the applicator which surrounds the applicator member.

Conformément à un mode de réalisation préféré de l'invention, l'organe applicateur est prolongé vers l'arrière par une tige présentant un évidement formant tiroir qui, lorsque l'applicateur est ouvert et que l'on déplace l'organe applicateur vers sa position d'utilisation, transfère un volume donné de produit cosmétique dans le volume qui est situé dans la partie avant du corps de l'applicateur, de manière à imprégner l'organe applicateur.In accordance with a preferred embodiment of the invention, the applicator member is extended towards the rear by a rod having a recess forming a drawer which, when the applicator is open and the applicator member is moved towards its position of use, transfers a given volume of cosmetic product into the volume which is located in the front part of the body of the applicator, so as to impregnate the applicator member.

Selon un autre mode de réalisation de l'invention, la tige qui soutient l'organe applicateur est creuse de sorte que la paroi extérieure de la tige peut coopérer avec une partie de la surface de la paroi poreuse pour s'opposer au passage du produit cosmétique du corps de l'applicateur où il est contenu vers le volume qui contient l'organe applicateur tandis que l'on peut provoquer par l'intérieur de la tige l'imprégnation contrôlée de l'organe applicateur avec le produit cosmétique.According to another embodiment of the invention, the rod which supports the applicator member is hollow so that the external wall of the rod can cooperate with part of the surface of the porous wall to oppose the passage of the product cosmetic of the body of the applicator where it is contained towards the volume which contains the applicator member while it is possible to induce from the inside of the rod the controlled impregnation of the applicator member with the cosmetic product.

Dans la description qui va suivre, on désigne l'extrémité de l'applicateur qui est obturé par le bouchon sous le terme de partie avant de l'applicateur, l'autre extrémité étant désignée sous le terme de partie arrière.In the description which follows, the end of the applicator is designated which is closed off by the plug under the term of the front part of the applicator, the other end being designated under the term of rear part.

De plus, les dessins représentent l'applicateur en position horizontale, mais il est clair que lors de son utilisation, l'applicateur peut être disposé dans toutes les positions.In addition, the drawings show the applicator in a horizontal position, but it is clear that when in use, the applicator can be arranged in all positions.

Pour cette raison, le produit cosmétique contenu à l'intérieur de l'applicateur n'a pas été représenté, car sa position dépend essentiellement de la position de l'applicateur et de l'agitation qui a été préalablement communiquée à ce dernier.For this reason, the cosmetic product contained inside the applicator has not been shown, because its position depends essentially on the position of the applicator and the agitation which has been previously communicated to the latter.

On a représenté sur les figures 1 et 2, un premier mode de réalisation de l'applicateur selon l'invention.There is shown in Figures 1 and 2, a first embodiment of the applicator according to the invention.

On voit sur ces figures le corps d'un applicateur qui est constitué par une partie arrière 1 constituant le réservoir de produit cosmétique et par une partie avant 2 qui est munie à son extrémité d'une ouverture.We see in these figures the body of an applicator which is constituted by a rear part 1 constituting the cosmetic product tank and by a front part 2 which is provided at its end with an opening.

Le produit cosmétique se trouve donc dans le volume 3 situé à l'intérieur de la partie arrière 1 de l'applicateur. Ce volume 3 contient à la manière connue une bille métallique 4 destinée à servir d'agitateur pour permettre une homogénéisation du produit cosmétique lorsque cela est nécessaire.The cosmetic product is therefore in the volume 3 located inside the rear part 1 of the applicator. This volume 3 contains in known manner a metal ball 4 intended to serve as an agitator to allow homogenization of the cosmetic product when necessary.

Un bouchon 5 qui s'engage par un filetage 6 sur la partie avant 2 du corps de l'applicateur permet d'obturer l'orifice terminal de cette dernière.A plug 5 which engages by a thread 6 on the front part 2 of the body of the applicator makes it possible to close the terminal orifice of the latter.

L'organe applicateur est constitué par un pinceau 7 muni à sa base d'un renflement 8 dont l'utilité sera décrite ultérieurement. Le pinceau 7 est supporté par une tige 9 elle-même reliée à une glissière cruciforme 10 dont l'autre extrémité supporte un contrepoids 11.The applicator member is constituted by a brush 7 provided at its base with a bulge 8, the usefulness of which will be described later. The brush 7 is supported by a rod 9 itself connected to a cruciform slide 10, the other end of which supports a counterweight 11.

Dans d'autres modes de réalisation, la forme de la glissière peut être différente, par exemple carrée, rectangulaire ou cylindrique.In other embodiments, the shape of the slide can be different, for example square, rectangular or cylindrical.

La glissière cruciforme 10 coulisse dans un orifice de forme correspondante située dans une douille 12 qui, à sa base 13, est rendue solidaire de la partie arrière 1 du corps de l'applicateur par un moyen quelconque tel que par collage.The cruciform slide 10 slides in a correspondingly shaped orifice located in a socket 12 which, at its base 13, is made integral with the rear part 1 of the body of the applicator by any means such as by gluing.

Des ouvertures 14 réalisées dans la paroi de la douille 12 permettent un libre passage du produit cosmétique entre le volume 3 et le volume 15 situé à l'intérieur de la douille 12.Openings 14 made in the wall of the socket 12 allow the cosmetic product to pass freely between the volume 3 and the volume 15 located inside the socket 12.

Les parties arrière 1 et avant 2 du corps de l'applicateur sont reliées entre elles en 16 de manière étanche, par exemple par collage.The rear 1 and front 2 parts of the body of the applicator are interconnected at 16 in a sealed manner, for example by gluing.

Conformément à l'invention, on a disposé à l'intérieur de la partie avant 2 du corps de l'applicateur, une paroi poreuse 17 qui, vers l'avant, délimite un volume 18 dans lequel se trouve située la partie avant du pinceau 7. Cette paroi poreuse peut être obtenue par exemple par frittage, par agglomération de fibres, ou être constituée par une mousse.According to the invention, there is disposed inside the front part 2 of the body of the applicator, a porous wall 17 which, towards the front, delimits a volume 18 in which is located the front part of the brush 7. This porous wall can be obtained for example by sintering, by agglomeration of fibers, or be constituted by a foam.

Entre le volume 18 et le volume 15 de la douille 12, la paroi poreuse 17 présente un diamètre 19 qui est supérieur au diamètre du renflement 8 qui est situé à la base du pinceau 7.Between the volume 18 and the volume 15 of the sleeve 12, the porous wall 17 has a diameter 19 which is greater than the diameter of the bulge 8 which is located at the base of the brush 7.

Les dimensions relatives du renflement 8 et de la partie 19 de la paroi poreuse sont telles que l'applicateur peut se déplacer librement entre la position fermée et la position ouverte malgré la viscosité du produit cosmétique, alors que ce dernier ne peut pas sensiblement passer des volumes 3 et 15 vers le volume 18 lorsque l'applicateur est en position fermée, en constituant ainsi un obturateur pour le produit cosmétique.The relative dimensions of the bulge 8 and of the part 19 of the porous wall are such that the applicator can move freely between the closed position and the open position despite the viscosity of the cosmetic product, while the latter cannot substantially pass from the volumes 3 and 15 towards volume 18 when the applicator is in the closed position, thus constituting a shutter for the cosmetic product.

On retrouve sur la figure 4, une représentation de la glissière cruciforme 10 qui coulisse dans un orifice de forme correspondante pratiquée dans le fond de la douille 12.FIG. 4 shows a representation of the cruciform slide 10 which slides in an orifice of corresponding shape made in the bottom of the socket 12.

On voit également sur la figure 4 comment de larges orifices 14 situés dans la partie cylindrique de la douille 12 permettent le libre passage du produit cosmétique du volume 3 vers le volume 15 qui est situé à l'intérieur de la douille 12.FIG. 4 also shows how large orifices 14 located in the cylindrical part of the sleeve 12 allow the cosmetic product to pass freely from volume 3 to volume 15 which is located inside the sleeve 12.

On retrouve les différentes pièces qui viennent d'être décrites sur la figure 2 dans laquelle le bouchon 5 a été enlevé tandis que l'organe applicateur constitué par le pinceau 7 a été déplacé vers l'extérieur.We find the different parts which have just been described in FIG. 2 in which the plug 5 has been removed while the applicator member constituted by the brush 7 has been moved outwards.

Ce déplacement peut s'effectuer à la manière connue, en agitant axialement l'applicateur, le pinceau 7 pouvant être amené soit en position sortie, soit en position rentrée, en raison de l'inertie du contrepoids 11 auquel il est relié.This movement can be carried out in the known manner, by shaking the applicator axially, the brush 7 being able to be brought either into the extended position or into the retracted position, due to the inertia of the counterweight 11 to which it is connected.

On suppose que, dans le cas de la figure 1, l'applicateur est neuf et que le produit cosmétique se trouve en totalité à l'intérieur de la partie arrière 1 du corps de l'applicateur, c'est-à-dire dans les volumes 3 et 15.It is assumed that, in the case of FIG. 1, the applicator is new and that the cosmetic product is entirely inside the rear part 1 of the body of the applicator, that is to say in volumes 3 and 15.

Lorsqu'après avoir enlevé le bouchon 5, on déplace brusquement l'applicateur vers la droite, le pinceau 7 sort de la partie avant du corps 2 de l'applicateur comme représenté sur la figure 2 en raison de l'inertie du contrepoids 11.When, after removing the cap 5, the applicator is suddenly moved to the right, the brush 7 comes out of the part front of the body 2 of the applicator as shown in FIG. 2 due to the inertia of the counterweight 11.

Lors de ce mouvement, le produit cosmétique qui est situé autour de la tige 9 qui présente un diamètre sensiblement plus faible que ceux du renflement 8 situé à la base du pinceau et de la glissière cruciforme 10, se trouve entraîné à l'intérieur du volume 18 où une quantité dosée de produit cosmétique se répand aussi.During this movement, the cosmetic product which is located around the rod 9 which has a diameter substantially smaller than those of the bulge 8 located at the base of the brush and the cruciform slide 10, is entrained inside the volume 18 where a dosed amount of cosmetic product also spreads.

Si l'on déplace l'applicateur vers la gauche d'un mouvement brusque, l'inertie du contrepoids 11 provoque le passage du pinceau 7 dans la position de la figure 1 en l'amenant au contact de la composition cosmétique qui a été préalablement introduite dans le volume 18 comme cela vient d'être expliqué.If the applicator is moved to the left with a sudden movement, the inertia of the counterweight 11 causes the brush 7 to pass into the position of FIG. 1 by bringing it into contact with the cosmetic composition which has been previously introduced in volume 18 as has just been explained.

La butée 10a qui est située à l'extrémité avant de la glissière cruciforme 10 limite le déplacement vers l'arrière de l'organe applicateur.The stop 10 a which is located at the front end of the cruciform slide 10 limits the rearward movement of the applicator member.

Un nouveau mouvement brusque de l'applicateur vers la droite provoque une nouvelle sortie du pinceau 7, qui est cette fois imprégné du produit cosmétique qui peut alors être appliqué par l'utilisateur.A new sudden movement of the applicator to the right causes a new exit of the brush 7, which is this time impregnated with the cosmetic product which can then be applied by the user.

On comprend ainsi comment il est possible d'amener successivement sur le pinceau des quantités données de produit cosmétique au fur et à mesure des besoins.We thus understand how it is possible to successively bring to the brush given quantities of cosmetic product as and when required.

Conformément à un mode de réalisation de l'invention, le volume 18 est délimité par une paroi poreuse 17 dont la partie arrière débouche sur le volume 15 et se trouve de ce fait au contact avec le produit cosmétique.In accordance with an embodiment of the invention, the volume 18 is delimited by a porous wall 17, the rear part of which opens onto the volume 15 and is therefore in contact with the cosmetic product.

Lorsque l'application du produit cosmétique est terminée, on ramène le pinceau 7 à l'intérieur de la cavité 18 que l'on obture avec le bouchon 5.When the application of the cosmetic product is finished, the brush 7 is brought back inside the cavity 18 which is closed with the plug 5.

Comme cela a été expliqué précédemment, le pinceau 7 contient encore une certaine quantité de produit cosmétique dont la viscosité a augmenté en raison d'un début d'évaporation du solvant que contient le produit cosmétique lors de l'application de ce dernier.As explained above, the brush 7 still contains a certain amount of cosmetic product whose viscosity has increased due to the start of evaporation of the solvent that the cosmetic product contains during the application of the latter.

Mais conformément à l'invention, la paroi 17 est perméable au solvant de telle sorte que ce dernier qui est contenu en plus grande quantité dans le produit cosmétique présent dans les chambres 3 et 15 diffuse à travers la paroi 17 pour venir dans le volume 18 où il se dissout dans la composition cosmétique qui est restée sur le pinceau 7.But according to the invention, the wall 17 is permeable to the solvent so that the latter which is contained in greater quantity in the cosmetic product present in the chambers 3 and 15 diffuses through the wall 17 to come into the volume 18 where it dissolves in the cosmetic composition which remained on the brush 7.

Cette dissolution empêche le produit cosmétique résiduel qui se trouve sur le pinceau 7 ou dans le volume 18, de durcir du fait qu'il se trouve en présence de son solvant exactement dans les mêmes conditions que le produit cosmétique qui se trouve dans les volumes 3 et 15.This dissolution prevents the residual cosmetic product which is on the brush 7 or in the volume 18, from hardening because it is in the presence of its solvent in exactly the same conditions as the cosmetic product which is in the volumes 3 and 15.

L'équilibre entre le produit cosmétique et son solvant se rétablit ainsi dans la chambre 18 ce qui évite une accumulation de produit cosmétique fortement visqueux ou même solidifié, sur le pinceau 7 et sur la paroi du volume 18.The balance between the cosmetic product and its solvent is thus restored in the chamber 18, which prevents an accumulation of highly viscous or even solidified cosmetic product, on the brush 7 and on the wall of the volume 18.

Conformément à l'invention, il est avantageux de réaliser également le renflement 8 qui est à la base du pinceau 7 à l'aide d'une matière poreuse, qui, comme la paroi 17, laisse passer le solvant du produit cosmétique de manière à faciliter encore le passage dudit solvant vers le pinceau 7 et le volume 18.According to the invention, it is advantageous to also make the bulge 8 which is at the base of the brush 7 using a porous material, which, like the wall 17, allows the solvent of the cosmetic product to pass so as to further facilitate the passage of said solvent towards the brush 7 and the volume 18.

Dans le mode de réalisation de la figure 3, la paroi poreuse 17 est remplacée par une pièce 20 constituée par deux parois 21a et 21b qui délimitent entre elles un volume annulaire 21 qui est en communication avec les volumes 15 et 3 qui ont été précédemment décrits.In the embodiment of FIG. 3, the porous wall 17 is replaced by a part 20 constituted by two walls 21 a and 21 b which delimit between them an annular volume 21 which is in communication with the volumes 15 and 3 which have been previously described.

La paroi intérieure 21b est munie de fentes longitudinales 22 de faible largeur qui, par leur dimension, permettent le passage du solvant contenu dans le produit cosmétique mais qui empêchent que, par capillarité, ce dernier les traverse.The inner wall 21b is provided with longitudinal slots 22 of small width which, by their size, allow the passage of the solvent contained in the cosmetic product but which prevent that, by capillarity, the latter passes through them.

On voit que la pièce 20 joue le même rôle que la paroi poreuse 17 en assurant le passage du solvant des volumes 15 et 3 vers le volume 18 dans lequel le produit cosmétique résiduel ne doit pas s'épaissir, tout en empêchant le produit cosmétique qui est conservé dans les volumes 3 et 15 de pénétrer dans le volume 18.It can be seen that the part 20 plays the same role as the porous wall 17 by ensuring the passage of the solvent from volumes 15 and 3 to volume 18 in which the residual cosmetic product must not thicken, while preventing the cosmetic product which is kept in volumes 3 and 15 from entering volume 18.

On retrouve sur la figure 5 qui est une vue en coupe selon V-V de la figure 3, le bouchon 5, la partie avant 2 de l'applicateur, les parois 21a et 21b qui délimitent le volume annulaire 21.In FIG. 5 which is a sectional view along VV of FIG. 3, we find the plug 5, the front part 2 of the applicator, the walls 21 a and 21 b which delimit the annular volume 21.

On y voit également les fentes de faibles épaisseurs 22 qui sont pratiquées dans la paroi 21b de manière à permettre le passage du solvant mais pas celui du produit cosmétique.We also see the thin slots 22 which are formed in the wall 21b so as to allow the passage of the solvent but not that of the cosmetic product.

Selon le troisième mode de réalisation de la figure 6, l'organe applicateur est constitué par un pinceau 7 supporté par une tige 9a qui est creuse et dont l'orifice intérieur 9b fait communiquer le pinceau 7 avec le volume 3 du corps 1 par l'intermédiaire d'une partie élargie 23 qui comporte une lèvre circulaire 24 sur laquelle vient prendre appui une bille 25 repoussée par un ressort 26 pour former une valve.According to the third embodiment of Figure 6, the applicator member is constituted by a brush 7 supported by a rod 9a which is hollow and whose internal orifice 9b communicates the brush 7 with the volume 3 of the body 1 by through an enlarged part 23 which has a circular lip 24 on which comes bear a ball 25 pushed back by a spring 26 to form a valve.

On comprend dans ces conditions, que lorsque le bouchon 5 est enlevé, on peut, en écrasant légèrement le corps souple 1 de l'applicateur faire sortir le pinceau 7, repousser la bille 25 et alimenter le pinceau avec le produit cosmétique qui s'écoule dans l'orifice 9b de la tige 9.It is understood under these conditions, that when the plug 5 is removed, it is possible, by slightly crushing the flexible body 1 of the applicator to bring out the brush 7, push the ball 25 and feed the brush with the cosmetic product which flows in hole 9b of rod 9.

Dans une variante, on fait varier le volume 3 du corps de l'applicateur, en le constituant en deux parties mobiles l'une par rapport à l'autre.In a variant, the volume 3 of the body of the applicator is varied, constituting it in two parts which are movable relative to one another.

Un contrepoids 11a en forme d'anneau permet par inertie de faire entrer ou sortir le pinceau 7.A counterweight 11 a in the form of a ring allows inertia to bring the brush 7 in or out.

On voit également sur la figure 6 comment la surface extérieure de la tige 9a coopère avec la surface 19 de la paroi poreuse 17 pour empêcher le produit cosmétique de s'écouler des volumes 3 et 15 vers le volume 18.Also shown in Figure 6 how the outer surface of the rod 9a cooperates with the surface 19 of the porous wall 17 to prevent the cosmetic product to flow volumes 3 and 15 to 18 volume.

Le transfert du solvant des volumes 15 et 3 vers le volume 18 n'implique pas que lors de ce transfert le solvant reste à l'état liquide ou à l'état gazeux. Cependant, compte-tenu de sa volatilité qui permet un séchage relativement rapide du produit cosmétique, le solvant traverse généralement la paroi sous forme de vapeur de manière à équilibrer sa tension de vapeur entre tous les volumes qui sont à l'intérieur du corps du récipient.The transfer of the solvent from volumes 15 and 3 to volume 18 does not imply that during this transfer the solvent remains in the liquid state or in the gaseous state. However, given its volatility which allows relatively quick drying of the cosmetic product, the solvent generally crosses the wall in the form of vapor so as to balance its vapor pressure between all the volumes which are inside the body of the container. .

Il est bien entendu que les modes de réalisation décrits ne présentent aucun caractère limitatif et qu'ils pourront recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention dont la caractéristique essentielle est constituée par la mise en communication du volume qui contient l'organe applicateur à l'état formé avec le volume qui contient le produit cosmétique de manière telle que ce dernier ne peut s'écouler vers le volume qui contient l'organe applicateur alors que son solvant peut passer de la partie de l'applicateur qui contient le produit cosmétique vers celle qui contient l'organe applicateur en empêchant ainsi que le produit cosmétique qui reste sur ou qui entoure l'organe applicateur s'épaississe et durcisse.It is understood that the embodiments described are in no way limiting and that they can receive any desirable modification without departing from the scope of the invention, the essential characteristic of which is the communication of the volume which contains the applicator member in the state formed with the volume which contains the cosmetic product in such a way that the latter cannot flow towards the volume which contains the applicator member while its solvent can pass from the part of the applicator which contains the cosmetic product towards that which contains the applicator organ, thereby preventing the cosmetic product which remains on or around the applicator organ from thickening and hardening.

En particulier, il est clair que l'organe applicateur peut être réalisé autrement que sous la forme d'un pinceau, par exemple à l'aide d'un organe poreux ou muni de cannelures longitudinales fines capables de retenir le produit cosmétique par capillarité. Cet organe applicateur peut-être également par exemple en mousse ou en une matière plastique frittée ou encore obtenu par flocage.In particular, it is clear that the applicator member can be produced other than in the form of a brush, for example using a porous member or provided with fine longitudinal grooves capable of retaining the cosmetic product by capillarity. This applicator member may also, for example, be made of foam or a sintered plastic material or else obtained by flocking.

De même, il est possible de réaliser différemment l'obturateur qui empêche à l'état fermé le produit cosmétique contenu à l'arrière du corps de l'applicateur de se déplacer pour venir dans le volume avant dans lequel se trouve l'organe applicateur.Likewise, it is possible to produce the shutter differently which, in the closed state, prevents the cosmetic product contained at the rear of the body of the applicator from moving to come into the front volume in which the applicator member is located. .

Enfin, il va de soi que l'invention peut également être appliqué à un applicateur de produit autre qu'un produit cosmétique mais qui présenterait les mêmes caractéristiques de viscosité et de solvant.Finally, it goes without saying that the invention can also be applied to a product applicator other than a cosmetic product but which would have the same viscosity and solvent characteristics.
