Description

La présente invention concerne un ensemble pour la distribution et l'application d'un produit fluide.The present invention relates to an assembly for the distribution and application of a fluid product.

On connait des ensembles d'application et de distribution d'un produit fluide dans lesquels on fixe, sur le goulot d'un flacon souple ou rigide, un porte-applicateur muni d'un applicateur, en particulier un pinceau, le porte-applicateur, et éventuellement l'applicateur, étant muni(s) d'un canal d'imprégnation de l'applicateur par le produit. De tels ensembles sont utilisés pour la distribution, par exemple, de vernis à ongles, de colle, de cirage ou d'encre.There are known sets of application and distribution of a fluid product in which is fixed, on the neck of a flexible or rigid bottle, an applicator holder provided with an applicator, in particular a brush, the applicator holder , and possibly the applicator, being provided with a channel for impregnating the applicator with the product. Such sets are used for the distribution, for example, of nail polish, glue, waxing or ink.

Cependant, dans ces ensembles il se produit fréquemment une distribution accidentelle de produit dans l'applicateur entre deux manipulations, et, par conséquent, le produit risque de souiller l'environnement si l'ensemble reste ouvert entre deux manipulations. De plus, l'utilisateur risque de se salir les mains lorsqu'il manipule l'ensemble d'application et distribution.However, in these assemblies there is frequently an accidental distribution of product in the applicator between two manipulations, and, consequently, the product risks contaminating the environment if the assembly remains open between two manipulations. In addition, the user may get their hands dirty when handling the application and dispensing assembly.

Pour éviter cet inconvénient, on a proposé dans EP-A-0 238 391 d'obturer le canal d'imprégnation en rendant mobile le porte-applicateur en translation entre une position où le canal d'imprégnation est obturé par le porte-applicateur et une position où ce canal d'imprégnation est ouvert, l'applicateur étant protégé, après application, dans sa position où il obture le canal d'imprégnation ; malheureusement, l'applicateur selon ce document est une mèche poreuse, imbibée de produit à appliquer par effet de capillarité, dont la contexture à forte perte de charge permet de retenir le produit contenu dans le canal d'imprégnation et de le refouler dans le flacon lors du retour du porte-applicateur vers sa position rétractée où il est protégé ; ainsi, un tel ensemble ne convient pas lorsque l'applicateur est un pinceau constitué d'une couronne de poils fixés autour du canal d'imprégnation.To avoid this drawback, it has been proposed in EP-A-0 238 391 to close the impregnation channel by making the applicator holder mobile in translation between a position where the impregnation channel is closed by the applicator holder and a position where this impregnation channel is open, the applicator being protected, after application, in its position where it closes the impregnation channel; unfortunately, the applicator according to this document is a porous wick, soaked with product to be applied by capillary effect, whose texture with high pressure drop makes it possible to retain the product contained in the impregnation channel and to discharge it into the bottle. when returning the applicator holder to its retracted position where it is protected; thus, such an assembly is not suitable when the applicator is a brush consisting of a crown of bristles fixed around the impregnation channel.

On a proposé dans US-A-4 279 527 un ensemble dont l'applicateur est un pinceau constitué d'une couronne de poils fixés autour du canal d'imprégnation, dans lequel le canal d'imprégnation est obturé à l'aide d'une aiguille, le porte-applicateur étant mobile en translation par rapport au porte-aiguille entre une position où l'aiguille obture le canal d'imprégnation et une position où ce canal d'imprégnation est ouvert. Cependant, l'ensemble décrit dans US-A 4 279 527 ne permet pas de protéger l'applicateur après application pour empêcher que le produit restant sur l'applicateur ne sèche trop vite ou ne vienne souiller les objets avec lesquels l'applicateur serait en contact.In US-A-4 279 527, an assembly has been proposed, the applicator of which is a brush consisting of a crown of bristles fixed around the impregnation channel, in which the impregnation channel is closed off with a needle, the applicator holder being movable in translation relative to the needle holder between a position where the needle closes the impregnation channel and a position where this impregnation channel is open. However, the assembly described in US Pat. No. 4,279,527 does not make it possible to protect the applicator after application to prevent the product remaining on the applicator from drying out too quickly or from contaminating the objects with which the applicator is in contact. contact.

La présente invention a, par conséquent, pour objet un ensemble pour la distribution et l'application d'un produit fluide comprenant un flacon contenant ledit produit, un porte-applicateur muni d'un applicateur et un canal d'imprégnation permettant d'imprégner l'applicateur avec ledit produit, le porte-applicateur étant mobile en translation par rapport à un manchon de manoeuvre porté par le flacon entre une position où le canal d'imprégnation est obturé et une position où ledit canal est ouvert, ledit manchon de manoeuvre pouvant être actionné manuellement en rotation par rapport au flacon et ayant une longueur telle qu'en position d'obturation du canal d'imprégnation, l'applicateur soit contenu tout entier dans ledit manchon de manoeuvre, ledit manchon de manoeuvre portant un filet interne, qui coopère avec un filet externe du porte-applicateur, ledit porte-applicateur étant bloqué en rotation par rapport au manchon de manoeuvre, caractérisé par le fait que, d'une part, l'obturateur du canal d'imprégnation est réalisé au moyen d'une aiguille solidaire d'un porte-aiguille fixé par rapport au flacon, que, d'autre part, l'applicateur est un pinceau constitué par une couronne de poils fixés annulairement autour du canal d'imprégnation et, qu'enfin, le porte-applicateur comporte un bourrelet d'étanchéité coopérant avec la paroi interne du manchon de manoeuvre et séparant en permanence le pinceau de la zone dudit manchon de manoeuvre qui porte le filet interne.The present invention therefore relates to an assembly for the distribution and application of a fluid product comprising a bottle containing said product, an applicator holder provided with an applicator and an impregnation channel for impregnating the applicator with said product, the applicator holder being movable in translation relative to an operating sleeve carried by the bottle between a position where the impregnation channel is closed and a position where said channel is open, said operating sleeve being able to be actuated manually in rotation relative to the bottle and having a length such that in the closed position of the impregnation channel, the applicator is entirely contained in said maneuvering sleeve, said maneuvering sleeve carrying an internal thread, which cooperates with an external thread of the applicator holder, said applicator holder being locked in rotation relative to the operating sleeve, characterized in that, part, the obturator of the impregnation channel is produced by means of a needle secured to a needle holder fixed relative to the bottle, that, on the other hand, the applicator is a brush constituted by a crown of bristles fixed annularly around the impregnation channel and, finally, the applicator holder comprises a sealing bead cooperating with the internal wall of the maneuvering sleeve and permanently separating the brush from the area of said maneuvering sleeve which carries the thread internal.

Par conséquent, dans l'ensemble de l'invention, le porte-applicateur est animé d'un mouvement de translation à la fois par rapport au manchon de manoeuvre et par rapport au porte-aiguille entre deux positions, une position où le canal d'imprégnation est obturé et où l'applicateur est entièrement contenu dans le manchon de manoeuvre et une position où le canal d'imprégnation est ouvert et où l'applicateur est sorti du manchon de manoeuvre de façon à permettre l'application du produit.Consequently, throughout the invention, the applicator holder is driven in a translational movement both relative to the operating sleeve and relative to the needle holder between two positions, a position where the channel d 'impregnation is closed and where the applicator is fully contained in the operating sleeve and a position where the impregnation channel is open and where the applicator is removed from the operating sleeve so as to allow the application of the product.

De préférence, selon l'invention, le manchon de manoeuvre porte un filet interne coopérant avec un filet externe du porte-applicateur, le porte-applicateur étant bloqué en rotation. Avantageusement, le filet externe du porte-applicateur ne comporte qu'une à deux spires se déplaçant entre les spires du filet interne du manchon de manoeuvre les plus proches du flacon et les spires les plus éloignées du flacon. Le porte-applicateur est, avantageusement, bloqué en rotation par une ailette solidaire dudit porte-applicateur, disposée dans une fente ménagée dans le porte-aiguille qui est fixe car il est solidaire du flacon.Preferably, according to the invention, the operating sleeve carries an internal thread cooperating with an external thread of the applicator holder, the applicator holder being locked in rotation. Advantageously, the external thread of the applicator holder has only one to two turns moving between the turns of the internal thread of the operating sleeve closest to the bottle and the furthest turns from the bottle. The applicator holder is advantageously locked in rotation by a fin secured to said applicator holder, disposed in a slot made in the needle holder which is fixed because it is secured to the bottle.

Selon un mode de réalisation préféré, l'ensemble de l'invention comporte un capuchon susceptible de recouvrir l'extrémité du manchon de manoeuvre lorsque l'applicateur est en position d'obturation du canal d'imprégnation. Ce capuchon comporte avantageusement une jupe d'étanchéité s'étendant vers l'intérieur du capuchon et susceptible de s'appuyer sur l'extrémité du manchon de manoeuvre contenant l'applicateur en position d'obturation du canal d'imprégnation.According to a preferred embodiment, the assembly of the invention comprises a cap capable of covering the end of the operating sleeve when the applicator is in the closed position of the impregnation channel. This cap advantageously comprises a sealing skirt extending towards the inside of the cap and capable of pressing on the end of the operating sleeve containing the applicator in the closed position of the impregnation channel.

Pour mieux faire comprendre l'invention, on va donner ci-après, à titre illustratif et non limitatif, la description d'un mode de réalisation d'un ensemble de distribution et d'application selon l'invention illustré sur le dessin annexé.To better understand the invention, we will give below, by way of illustration and not limitation, the description of an embodiment of a dispensing and application assembly according to the invention illustrated in the accompanying drawing.

L'ensemble représenté sur la figure 1, désigné par la référence 1, est un ensemble de distribution et d'application de vernis à ongles. Il est constitué par un flacon semi-rigide 2 cylindrique de révolution susceptible de contenir le vernis à ongles. Dans le flacon 2, selon le mode de réalisation représenté, est disposée une bille 3 destinée à l'agitation du vernis et à la mise en suspension des pigments contenus dans ce vernis. Le flacon 2 est muni d'un fond 4, d'une paroi latérale cylindrique 5 et, du côté opposé au fond 4, d'un goulot 6 ménageant une ouverture 7. Le goulot 6 est constitué, d'une part, d'une jupe tronconique 8 se rattachant à la paroi cylindrique 5 du flacon 2 par un épaulement 9 perpendiculaire à l'axe du flacon et portant un bourrelet de claquage 10 et, d'autre part, d'une jupe cylindrique 11 ayant le même diamètre que la partie de plus faible diamètre de la jupe tronconique 8 (voir figures 2 et 3).The assembly shown in Figure 1, designated by the reference 1, is a set of distribution and application of nail polish. It consists of a semi-rigid bottle 2 cylindrical of revolution capable of containing the nail varnish. In the bottle 2, according to the embodiment shown, is arranged a ball 3 intended for stirring the varnish and for suspending the pigments contained in this varnish. The bottle 2 is provided with a bottom 4, with a cylindrical side wall 5 and, on the side opposite the bottom 4, with a neck 6 providing an opening 7. The neck 6 consists, on the one hand, of a tapered skirt 8 connected to the cylindrical wall 5 of the bottle 2 by a shoulder 9 perpendicular to the axis of the bottle and carrying a flange 10 and, on the other hand, a cylindrical skirt 11 having the same diameter as the part of smaller diameter of the frustoconical skirt 8 (see Figures 2 and 3).

Sur le goulot 6 du flacon 2, est fixé un porte-aiguille 12 portant une aiguille métallique 13. Le porte-aiguille ne peut donc se déplacer ni en translation, ni en rotation par rapport au flacon 2. Le porte-aiguille 12 comporte une portion cylindrique externe 14 dont un bord libre repose sur l'épaulement 9 du goulot et qui a un diamètre externe égal au diamètre externe de la paroi cylindrique 5 du flacon 2. La face interne de la portion 14 est munie d'une gorge annulaire 15 susceptible de coopérer, par claquage, avec le bourrelet 10 du goulot 6 du flacon 2. La portion externe 14 est reliée, par une collerette annulaire 16 perpendiculaire à l'axe longitudinal du flacon, à une jupe d'étanchéité 17 comportant une partie cylindrique 18 ayant un diamètre externe égal, au jeu nécessaire pour le montage près, au diamètre interne de la jupe cylindrique 11 du goulot 6 du flacon 2. La partie cylindrique 18 de la jupe d'étanchéité 17 se prolonge par une partie tronconique 19 vers le fond 4 du flacon 2. La partie tronconique 19 de la jupe d'étanchéité 17 est reliée par l'intermédiaire d'une collerette 20 transversale à un manchon 21, s'étendant vers l'extérieur du flacon 2, ménageant un passage 22 pour le vernis à distribuer. Dans le manchon 21, est ménagée une fente longitudinale 23. L'extrémité du manchon 21, extérieure au flacon, porte un moyeu 24 qui est relié audit manchon 21 par trois bras 25 ; trois ouvertures 54 (voir figure 4) sont ainsi ménagées entre les bras 25, le moyeu 24 et le manchon 21. Sur le moyeu 24 est fixé un tube 26 dans lequel l'aiguille 13 est enfoncée à force. Le porte-aiguille 12 comporte également, sur la collerette 16, une jupe de fixation 27 du manchon de manoeuvre 40 ayant un diamètre voisin du diamètre d'ouverture du goulot 6 et portant sur sa face externe un bourrelet annulaire 28 externe et sur sa face interne une rainure annulaire interne 29.On the neck 6 of the bottle 2, is fixed a needle holder 12 carrying a metal needle 13. The needle holder can therefore neither move in translation nor in rotation relative to the bottle 2. The needle holder 12 has a external cylindrical portion 14 of which a free edge rests on the shoulder 9 of the neck and which has an external diameter equal to the external diameter of the cylindrical wall 5 of the bottle 2. The internal face of the portion 14 is provided with an annular groove 15 capable of cooperating, by breakdown, with the bead 10 of the neck 6 of the bottle 2. The external portion 14 is connected, by an annular flange 16 perpendicular to the longitudinal axis of the bottle, to a sealing skirt 17 comprising a cylindrical part 18 having an external diameter equal, to the clearance necessary for mounting, to the internal diameter of the cylindrical skirt 11 of the neck 6 of the bottle 2. The cylindrical part 18 of the sealing skirt 17 is extended by a frustoconical part 19 towards the bottom 4 of the bottle 2. The frustoconical part 19 of the sealing skirt 17 is connected by means of a transverse flange 20 to a sleeve 21, extending towards the outside of the bottle 2, providing a passage 22 for the varnish to be distributed. In the sleeve 21, a longitudinal slot 23 is formed. The end of the sleeve 21, outside the bottle, carries a hub 24 which is connected to said sleeve 21 by three arms 25; three openings 54 (see Figure 4) are thus formed between the arms 25, the hub 24 and the sleeve 21. On the hub 24 is fixed a tube 26 in which the needle 13 is forced. The needle holder 12 also comprises, on the collar 16, a fixing skirt 27 of the operating sleeve 40 having a diameter close to the opening diameter of the neck 6 and carrying on its external face an external annular bead 28 and on its face internal an internal annular groove 29.

Sur le manchon 21 est enfilé un porte-applicateur, ici donc un porte-pinceau 30, portant un pinceau 38, susceptible de se déplacer, en translation, longitudinalement, en coulissant sur le manchon 21. Le porte-pinceau 30 est formé d'un premier élément cylindrique 31 ayant, au jeu nécessaire près, un diamètre interne égal au diamètre externe du manchon 21, ce premier élément cylindrique 31 portant, à son extrémité tournée vers l'intérieur du flacon, une lèvre d'étanchéité 34 coopérant, de façon étanche, avec la surface extérieure du manchon 21. A son autre extrémité, le premier élément cylindrique 31 est relié à un élément tronconique 32 de diamètre décroissant vers l'extérieur raccordé à un second élément cylindrique 33 ayant un plus faible diamètre que le premier élément 31. Sur l'élément tronconique 32 et sur une partie du premier élément cylindrique 31 est disposée une ailette radiale 35 dont le bord interne est parallèle à l'axe longitudinal de l'ensemble. Cette ailette 35 est susceptible de coopérer avec la fente 23 du manchon 21 du porte-aiguille 12. La paroi externe du premier élément cylindrique 31 du porte-pinceau 30 est munie d'un filet 37 hélicoïdal d'un pas et demi. L'extrémité tournée vers l'extérieur du porte-pinceau 30 porte un bourrelet d'étanchéité 36. Le pinceau 38 est constitué par un clip annulaire 39 dans lequel est pincée une couronne de poils, le clip ménageant un canal 53. Le clip 39 est engagé à force dans l'extrémité tournée vers l'extérieur de l'élément 33, de plus faible diamètre, du porte-pinceau 30.On the sleeve 21 is fitted an applicator holder, here therefore a brush holder 30, carrying a brush 38, capable of moving, in translation, longitudinally, sliding on the sleeve 21. The brush holder 30 is formed of a first cylindrical element 31 having, apart from the necessary clearance, an internal diameter equal to the external diameter of the sleeve 21, this first cylindrical element 31 carrying, at its end turned towards the inside of the bottle, a sealing lip 34 cooperating, sealingly, with the external surface of the sleeve 21. At its other end, the first cylindrical element 31 is connected to a frustoconical element 32 of decreasing diameter towards the outside connected to a second cylindrical element 33 having a smaller diameter than the first element 31. On the element frustoconical 32 and on a part of the first cylindrical element 31 is disposed a radial fin 35 whose internal edge is parallel to the longitudinal axis of the assembly. This fin 35 is capable of cooperating with the slot 23 of the sleeve 21 of the needle holder 12. The external wall of the first cylindrical element 31 of the brush holder 30 is provided with a helical thread 37 with a pitch and a half. The outwardly facing end of the brush holder 30 carries a sealing bead 36. The brush 38 consists of an annular clip 39 in which a crown of bristles is pinched, the clip providing a channel 53. The clip 39 is forcibly engaged in the outwardly facing end of the element 33, of smaller diameter, of the brush holder 30.

Le porte-pinceau 30 est entouré d'un manchon de manoeuvre 40 fixé sur la jupe de fixation 27 du porte aiguille 12. Ce manchon 40 comporte un premier élément cylindrique de faible épaisseur 41 muni d'un bourrelet annulaire 42 de claquage coopérant avec la rainure annulaire 29 de la jupe de fixation 27 de façon que le manchon de manoeuvre 40 puisse tourner par rapport au porte-aiguille 12 et, par conséquent, par rapport au flacon 2. Le deuxième élément cylindrique 43 est plus épais que le premier élément cylindrique 41 ; les surfaces internes de l'élément cylindrique 41 et du deuxième élément cylindrique 43 sont dans le prolongement l'une de l'autre, et la surface externe du second élément cylindrique 43 est dans le prolongement de la surface externe de la jupe de fixation 27.The brush holder 30 is surrounded by an operating sleeve 40 fixed on the fixing skirt 27 of the needle holder 12. This sleeve 40 comprises a first thin cylindrical element 41 provided with an annular bead 42 of snap cooperating with the annular groove 29 of the fixing skirt 27 so that the operating sleeve 40 can rotate relative to the needle holder 12 and, consequently, relative to the bottle 2. The second cylindrical element 43 is thicker than the first cylindrical element 41; the internal surfaces of the cylindrical element 41 and the second cylindrical element 43 are in line with one another, and the external surface of the second cylindrical element 43 is in line with the external surface of the fixing skirt 27 .

La surface interne des éléments cylindriques 41 et 43 porte un filet 44 destiné à coopérer avec le filet 37 de l'élément cylindrique 31 du porte-pinceau 30. Un troisième élément 45 du manchon de manoeuvre 40 est un élément tronconique de même angle au sommet que celui de l'élément tronconique 32 du porte-pinceau 30 et un quatrième élément 46 est un élément cylindrique ayant un diamètre interne égal, au jeu nécessaire près, au diamètre externe de l'élément cylindrique 33 du porte-pinceau 30. L'élément cylindrique 46 se prolonge vers l'extérieur selon une collerette tronconique 47.The internal surface of the cylindrical elements 41 and 43 carries a net 44 intended to cooperate with the net 37 of the cylindrical element 31 of the brush holder 30. A third element 45 of the operating sleeve 40 is a frustoconical element with the same angle at the top than that of the frustoconical element 32 of the brush holder 30 and a fourth element 46 is a cylindrical element having an internal diameter equal, apart from the necessary clearance, to the external diameter of the cylindrical element 33 of the brush holder 30. The cylindrical element 46 is extended outwards according to a frustoconical flange 47.

Un capuchon 48 (figure 3) protège le manchon de manoeuvre 40 et le pinceau 38 contenu dans ledit manchon 40. Le capuchon 48 comporte une jupe de fixation cylindrique 49 dont le diamètre extérieur est le même que celui du flacon 2 et de la jupe externe 14 du porte-aiguille 12 et portant sur sa face interne un bourrelet de claquage 50 susceptible de coopérer avec le bourrelet externe 28 de la jupe de fixation 27 du porte-aiguille 12. Une jupe d'étanchéité 52 est portée par le fond 51 du capuchon 48 et vient s'appuyer, lorsque le capuchon 48 est en place, sur l'élément cylindrique 46 du manchon de manoeuvre 40.A cap 48 (FIG. 3) protects the operating sleeve 40 and the brush 38 contained in said sleeve 40. The cap 48 comprises a cylindrical fixing skirt 49 whose outside diameter is the same as that of the bottle 2 and of the external skirt 14 of the needle holder 12 and carrying on its internal face a snap bead 50 capable of cooperating with the external bead 28 of the fixing skirt 27 of the needle holder 12. A sealing skirt 52 is carried by the bottom 51 of the cap 48 and comes to bear, when the cap 48 is in place, on the cylindrical element 46 of the operating sleeve 40.

L'ensemble 1 de distribution et d'application fonctionne de la façon décrite ci-après.The distribution and application assembly 1 operates in the manner described below.

En position de stockage, comme illustré sur la figure 3, le capuchon 48 est fixé sur le porte-aiguille 12 et le porte-pinceau 30 est disposé de façon telle que l'ailette 35 soit en butée dans le bas de la fente 23 du porte-aiguille 12 et que le filet 37 du porte-pinceau 30 coopère avec les spires du filet 44 de la capsule de manoeuvre 40 les plus proches du flacon. Le pinceau est alors entièrement contenu dans l'élément cylindrique 46 du manchon de manoeuvre 40. L'aiguille 13 obture le canal 53 du pinceau 38.In the storage position, as illustrated in FIG. 3, the cap 48 is fixed on the needle holder 12 and the brush holder 30 is arranged so that the fin 35 is in abutment at the bottom of the slot 23 of the needle holder 12 and that the thread 37 of the brush holder 30 cooperates with the turns of the thread 44 of the operating cap 40 closest to the bottle. The brush is then entirely contained in the cylindrical element 46 of the operating sleeve 40. The needle 13 closes the channel 53 of the brush 38.

Lorsque l'utilisateur désire appliquer le produit contenu dans le flacon 2, il enlève le capuchon 48, ce qui dégage le manchon de manoeuvre 40. Il fait ensuite tourner manuellement ledit manchon de manoeuvre 40 par rapport au flacon. Par action du filet 44 du manchon de manoeuvre 40 sur le filet 37 du porte-pinceau 30, qui ne peut pas tourner car il est bloqué par la languette 35 disposée dans la fente 23 du porte-aiguille 12, le porte-pinceau 30 est animé d'un mouvement de translation vers l'extérieur suivant l'axe de l'ensemble, l'élément 31 du porte-pinceau 30 coulissant sur le manchon 21 du porte-aiguille 12 et l'élément 33 coulissant dans l'élément 46 du manchon de manoeuvre 40. Le pinceau 38 sort de l'élément 46 du manchon de manoeuvre 40 et le canal 53 se dégage de l'aiguille 13. Le produit contenu dans le flacon 2 peut alors passer par le passage 22, ménagé par le manchon 21 du porte-aiguille 12, à travers les ouvertures 54 entre le moyeu 24 et ses bras 25 de fixation au manchon 21, à travers l'espace interne 55 du porte-pinceau 30 autour de l'aiguille 13, et, pour finir, à travers le canal 53 du pinceau 38 (voir figure 2). En fin de course, le porte-pinceau 30 vient en butée contre la collerette 47 du manchon de manoeuvre 40, les éléments tronconiques 32 du porte-pinceau 30 et 45 du manchon de manoeuvre 40 sont disposés l'une contre l'autre et le filet 37 du porte-pinceau coopère avec les spires les plus externes du filet 44 du manchon de manoeuvre 40. Lorsque l'utilisateur souhaite appliquer le vernis sur les ongles, il exerce avec le pouce et l'index une légère pression sur le corps du flacon semi-rigide 2, le pinceau 38 de l'ensemble applicateur 1 étant tourné vers le bas. Le produit imprègne alors les poils du pinceau 38 et le vernis peut être appliqué sur les ongles.When the user wishes to apply the product contained in the bottle 2, he removes the cap 48, which releases the operating sleeve 40. He then manually turns said operating sleeve 40 relative to the bottle. By action of the thread 44 of the operating sleeve 40 on the thread 37 of the brush holder 30, which cannot rotate because it is blocked by the tongue 35 disposed in the slot 23 of the needle holder 12, the brush holder 30 is driven in an outward translation movement along the axis of the assembly, the element 31 of the brush holder 30 sliding on the sleeve 21 of the needle holder 12 and the element 33 sliding in the element 46 from the operating sleeve 40. The brush 38 comes out of the element 46 from the operating sleeve 40 and the channel 53 emerges from the needle 13. The product contained in the bottle 2 can then pass through the passage 22, formed by the sleeve 21 of the needle holder 12, through the openings 54 between the hub 24 and its arms 25 for attachment to the sleeve 21, through the internal space 55 of the brush holder 30 around the needle 13, and, finally, through the channel 53 of the brush 38 (see FIG. 2). At the end of the stroke, the brush holder 30 abuts against the flange 47 of the maneuvering sleeve 40, the frustoconical elements 32 of the brush holder 30 and 45 of the maneuvering sleeve 40 are arranged one against the other and the thread 37 of the brush holder cooperates with the outermost turns of the thread 44 of the operating sleeve 40. When the user wishes to apply the varnish to the nails, he exerts a slight pressure on the body of the thumb with the index finger semi-rigid bottle 2, the brush 38 of the applicator assembly 1 being turned downwards. The product then permeates the bristles of the brush 38 and the varnish can be applied to the nails.

Après avoir appliqué le produit, l'utilisateur tourne le manchon de manoeuvre 40 par rapport au flacon 2 de façon à donner au porte-pinceau 30 un mouvement de translation inverse du mouvement précédent jusqu'à ce que le porte-pinceau 30 revienne dans sa position de stockage. Il est à noter que, même si le capuchon 48 n'est pas mis en place immédiatement, le vernis contenu dans le flacon 2 ne peut pas être accidentellement distribué : l'aiguille 13 obture le canal 53 du pinceau 38, et le pinceau 38, protégé par le manchon de manoeuvre 40, ne peut pas entrer en contact avec des objets de l'environnement et les salir.After applying the product, the user turns the maneuvering sleeve 40 relative to the bottle 2 so as to give the brush holder 30 a movement of translation opposite to the previous movement until the brush holder 30 returns to its storage position. It should be noted that, even if the cap 48 is not put in place immediately, the varnish contained in the bottle 2 cannot be accidentally dispensed: the needle 13 closes the channel 53 of the brush 38, and the brush 38 , protected by the operating sleeve 40, cannot come into contact with environmental objects and soil them.
