Description

Distributeur de produit fluide  Fluid dispenser
La présente invention concerne un distributeur de produit fluide comprenant un réservoir de produit fluide, une pompe montée sur le réservoir et un poussoir monté sur la pompe pour l'actionner. Il s'agit là d'une conception tout à fait classique et minimaliste pour un distributeur dans les domaines de la parfumerie, de la cosmétique ou encore de la pharmacie. The present invention relates to a fluid dispenser comprising a fluid reservoir, a pump mounted on the reservoir and a pusher mounted on the pump for actuating it. This is a very classic and minimalist design for a distributor in the fields of perfumery, cosmetics or even pharmacy.
Dans l'art antérieur, on connaît déjà de nombreux distributeurs comprenant un applicateur de produit fluide qui est en communication directe avec le produit fluide stocké dans le réservoir. L'applicateur peut être solidaire du réservoir, ou au contraire d'un organe de préhension qui peut être détaché ou séparé du réservoir. Le chargement de l'applicateur en produit fluide peut s'effectuer par retournement ou secouage du distributeur, ou encore par aspiration, comme par exemple dans le document ...  In the prior art, numerous dispensers are already known comprising a fluid product applicator which is in direct communication with the fluid product stored in the reservoir. The applicator can be integral with the reservoir, or on the contrary a gripping member that can be detached or separated from the reservoir. The loading of the applicator fluid product can be done by turning or shaking the dispenser, or by suction, as for example in the document ...
Dans l'art antérieur, on connaît également les distributeurs classiques avec un réservoir, une pompe montée sur le réservoir et un poussoir monté sur la pompe pour l'actionner.  In the prior art, conventional distributors with a tank, a pump mounted on the tank and a pusher mounted on the pump for actuating it are also known.
Ces deux types de distributeurs (à applicateur et à pompe) appartiennent à des familles bien distinctes et à des applications différenciées.  These two types of dispensers (applicator and pump) belong to distinct families and differentiated applications.
La présente invention a pour objet de définir un nouveau type de distributeur de produit fluide dont les caractéristiques de base sont celles d'un distributeur classique à pompe et poussoir. Un autre but de la présente invention est de combiner dans un seul distributeur les avantages des deux types de distributeurs (applicateur et à pompe). Encore un autre but de la présente invention est de garantir un chargement répétitif et contrôlé d'un applicateur de produit fluide. Encore un autre but de la présente invention est de combiner les gestuelles caractéristiques des distributeurs à applicateur et des distributeurs à pompe.  The object of the present invention is to define a new type of fluid dispenser whose basic characteristics are those of a conventional pump and pusher dispenser. Another object of the present invention is to combine in a single distributor the advantages of the two types of distributors (applicator and pump). Yet another object of the present invention is to ensure a repetitive and controlled loading of a fluid applicator. Yet another object of the present invention is to combine the characteristic gestures of dispenser applicators and pump dispensers.
Pour atteindre ces différents buts, la présente invention propose que le poussoir comprenne une embase montée fixement sur la pompe et un organe de préhension monté de manière amovible sur l'embase, l'organe de préhension comprenant un applicateur de produit fluide, l'organe de préhension définissant une surface d'appui sur laquelle on peut appuyer axialement pour entraîner l'embase en déplacement et ainsi actionner la pompe pour charger l'applicateur en produit fluide. Par rapport à un distributeur à pompe classique, le distributeur de l'invention se distingue par la présence de l'applicateur qui est solidaire du poussoir, lui-même incorporé dans un organe de préhension. Par rapport à un distributeur classique à applicateur, la présente invention se distingue par la présence d'une pompe pour acheminer le produit fluide à l'applicateur et d'un poussoir sur lequel l'applicateur d'un produit fluide est monté. Avec le distributeur de la présente invention, l'utilisateur combine les deux gestuelles, les deux types de distributeurs, à savoir l'actionnement d'un poussoir pour distribuer une dose de produit fluide et l'utilisation de l'organe de préhension qui est détaché du reste du distributeur pour être appliqué sur une surface d'application tels que la peau, les ongles, les cheveux, etc. To achieve these various goals, the present invention proposes that the pusher comprises a base mounted fixedly on the pump and a gripping member removably mounted on the base, the body of gripper comprising a fluid product applicator, the gripping member defining a bearing surface on which can be axially pressed to drive the base in displacement and thus actuate the pump to charge the applicator fluid product. Compared to a conventional pump dispenser, the dispenser of the invention is distinguished by the presence of the applicator which is integral with the pusher, itself incorporated into a gripping member. Compared to a conventional dispenser applicator, the present invention is distinguished by the presence of a pump for conveying the fluid to the applicator and a pusher on which the applicator of a fluid product is mounted. With the dispenser of the present invention, the user combines the two gestures, the two types of dispensers, namely the actuation of a pusher to dispense a dose of fluid and the use of the gripping member which is detached from the rest of the dispenser to be applied to an application surface such as skin, nails, hair, etc.
Selon une caractéristique avantageuse de la présente invention, l'embase comprend une coupelle de réception pour l'applicateur, la coupelle formant un orifice d'alimentation relié à la pompe. La coupelle de réception peut directement être montée sur la tige d'actionnement de la pompe. De préférence, la coupelle épouse la forme de l'applicateur, et définit avantageusement des canaux d'alimentation qui s'étendent radialement vers l'extérieur à partir de l'orifice d'alimentation. On assure ainsi que la totalité de la dose distribuée par la pompe atteint l'applicateur de produit fluide, et ceci de manière contrôlée, grâce à la présence des canaux d'alimentation qui s'étendent dans une direction déterminée.  According to an advantageous characteristic of the present invention, the base comprises a receiving cup for the applicator, the cup forming a supply port connected to the pump. The receiving cup can be directly mounted on the actuating rod of the pump. Preferably, the cup conforms to the shape of the applicator, and advantageously defines supply channels that extend radially outwardly from the supply port. This ensures that the entire dose dispensed by the pump reaches the fluid applicator, and this in a controlled manner, thanks to the presence of supply channels that extend in a specific direction.
Selon un autre aspect avantageux de l'invention, l'organe de préhension est monté de manière étanche sur l'embase, avantageusement par écrasement d'un joint. Ainsi, l'applicateur est isolé hermétiquement à l'intérieur de sa coupelle de réception. De préférence, l'organe de préhension est connecté de manière amovible à l'embase par des moyens magnétiques. Il n'est pas nécessaire que les moyens magnétiques soient situés sur l'embase, mais simplement que les moyens magnétiques permettent une connexion de manière amovible entre l'organe de préhension et l'embase. Les moyens magnétiques, en tant que moyens de connexion, sont particulièrement avantageux, car ils permettent un repositionnement de l'organe de préhension sur l'embase sans avoir à exercer une force d'appui sur l'embase. On évite ainsi un actionnement intempestif ou involontaire de la pompe. D'autre part, les moyens magnétiques permettent un repositionnement quasi-automatique et centré. Enfin, les moyens magnétiques, du fait de la force d'attraction exercée, permettent l'écrasement du joint qui permet d'isoler hermétiquement l'applicateur à l'intérieur de sa coupelle de réception. According to another advantageous aspect of the invention, the gripping member is sealingly mounted on the base, advantageously by crushing a seal. Thus, the applicator is hermetically sealed inside its receiving cup. Preferably, the gripping member is removably connected to the base by magnetic means. It is not necessary that the magnetic means be located on the base, but simply that the magnetic means allow a detachably connecting between the gripping member and the base. The magnetic means, as connecting means, are particularly advantageous because they allow a repositioning of the gripping member on the base without having to exert a pressing force on the base. This avoids inadvertent or involuntary operation of the pump. On the other hand, the magnetic means allow a quasi-automatic and centered repositioning. Finally, the magnetic means, because of the force of attraction exerted, allow the crushing of the seal which allows to hermetically isolate the applicator inside its receiving cup.
Selon une autre caractéristique intéressante de l'invention, l'embase coulisse, avantageusement de manière étanche, dans une douille de guidage axial solidaire du réservoir. On garantit ainsi qu'il n'y a pas de fuite de produit fluide à l'intérieur du distributeur lors de son déplacement coulissant à l'intérieur de la douille de guidage.  According to another advantageous characteristic of the invention, the base slides, advantageously sealingly, in an axial guide sleeve integral with the reservoir. This ensures that there is no leakage of fluid inside the dispenser during its sliding movement inside the guide sleeve.
Selon un autre aspect particulièrement avantageux de la présente invention, un passage de retour de produit fluide relie l'embase au réservoir. Ainsi, le produit fluide distribué par la pompe dans la coupelle de réception retourne vers le réservoir, dès que l'applicateur est rempli ou saturé de produit fluide. On peut par exemple imaginer qu'un utilisateur appuie plusieurs fois sur le poussoir de manière à distribuer une quantité de produit fluide très importante. L'excès de produit fluide injecté dans la coupelle de réception pourra ainsi être réorienté vers le réservoir. On garantit ainsi que l'applicateur est toujours rempli ou imprégné avec la même quantité de produit fluide et on évite tout risque de fuite de produit fluide créé par une surpression à l'intérieur de la coupelle de réception.  According to another particularly advantageous aspect of the present invention, a fluid return passageway connects the base to the reservoir. Thus, the fluid dispensed by the pump into the receiving cup returns to the reservoir, as soon as the applicator is filled or saturated with fluid. For example, it is possible to imagine that a user presses the pusher several times so as to dispense a very large quantity of fluid product. The excess fluid product injected into the receiving cup may thus be redirected towards the reservoir. This ensures that the applicator is always filled or impregnated with the same amount of fluid and avoids any risk of fluid leakage created by an overpressure inside the receiving cup.
Selon un mode de réalisation avantageux, l'organe de préhension comprend un corps de préhension dans lequel un bouton-poussoir est déplaçable en va-et-vient, l'applicateur étant solidaire en déplacement de ce bouton-poussoir, qui est avantageusement sollicité en position de repos par un ressort de rappel qui agit entre le corps de préhension et le bouton- poussoir. De préférence, l'applicateur est connecté à un support de montage qui coulisse de manière étanche dans le corps de préhension, le bouton- poussoir étant en prise avec ce support de montage. Il s'agit là d'un mode de réalisation particulièrement abouti, mais on peut également imaginer que l'organe de préhension dans son ensemble constitue un bouton poussoir sur lequel l'applicateur de produit fluide est monté. According to an advantageous embodiment, the gripping member comprises a gripping body in which a push button is movable back and forth, the applicator being integral in displacement of this push button, which is advantageously solicited by rest position by a return spring which acts between the gripping body and the push button. Preferably, the applicator is connected to a mounting bracket which slides tightly in the gripping body, the pushbutton being engaged with this mounting bracket. This is a particularly successful embodiment, but one can also imagine that the gripping member as a whole is a push button on which the fluid applicator is mounted.
L'esprit de la présente invention réside dans le fait d'associer un applicateur de produit fluide à un poussoir servant à actionner une pompe pour charger l'applicateur, le poussoir faisant partie d'un organe de préhension que l'utilisateur peut saisir pour le séparer du restant du distributeur et mettre en contact l'applicateur avec une surface d'application telle que la peau.  The spirit of the present invention resides in the fact of associating a fluid applicator with a pusher serving to actuate a pump for charging the applicator, the pusher being part of a gripping member which the user can grasp for separate it from the remainder of the dispenser and bring the applicator into contact with an application surface such as the skin.
L'invention sera maintenant décrite plus en détail en référence aux dessins joints, donnant à titre d'exemples non limitatifs, deux modes de réalisation de l'invention.  The invention will now be described in more detail with reference to the accompanying drawings, giving by way of non-limiting examples two embodiments of the invention.

La figure 4 est une vue similaire à celle de la figure 2 pour un second mode de réalisation de l'invention.  Figure 4 is a view similar to that of Figure 2 for a second embodiment of the invention.
On se référera tout d'abord aux figures 1 et 2 pour décrire en détail la structure du distributeur de produit fluide selon le premier mode de réalisation de l'invention. On peut voir que le distributeur présente une configuration allongée qui fait penser à celle d'un stylo ou d'un feutre. En effet, le réservoir de produit fluide 1 est fin et long. Dans le mode de réalisation non limitatif des figures 1 et 2, le réservoir 1 comprend un piston suiveur 1 1 destiné à se déplacer par coulissement étanche axial à l'intérieur du réservoir, afin de diminuer son volume utile, à mesure que du produit fluide est distribué. En position de départ, le piston suiveur 1 1 est disposé à proximité d'une extrémité du réservoir opposé à un col 12 sur lequel une pompe 2 est montée. Etant donné que la pompe 2 n'est pas un élément critique pour la présente invention, elle ne sera pas décrite en détail. Elle peut être d'un type tout à fait classique, avec un corps de pompe définissant une entrée avec un clapet d'entrée, une chambre de pompe, un piston, et un clapet de sortie qui permet au produit fluide mis sous pression dans la chambre de pompe d'être refoulé à travers une tige d'actionnement creuse 21 . Pour la fixation sur le col 12, la pompe 2 est pourvue d'une bague de fixation dans laquelle la pompe est reçue fixement et qui vient s'accrocher à l'intérieur ou à l'extérieur du col 12 de manière fixe et étanche. Il s'agit là de caractéristique tout à fait classique pour une pompe et sa fixation sur un réservoir dans le domaine de la pharmacie, de la cosmétique ou encore de la parfumerie. On peut toutefois remarquer que le réservoir 1 définit un alésageReferring first to Figures 1 and 2 to describe in detail the structure of the fluid dispenser according to the first embodiment of the invention. It can be seen that the dispenser has an elongated configuration reminiscent of that of a pen or felt. Indeed, the fluid reservoir 1 is thin and long. In the non-limiting embodiment of FIGS. 1 and 2, the reservoir 1 comprises a follower piston 1 1 intended to move by axial leaktight sliding inside. of the tank, in order to reduce its useful volume, as fluid is dispensed. In the starting position, the follower piston 1 1 is disposed near an end of the tank opposite a neck 12 on which a pump 2 is mounted. Since pump 2 is not a critical element for the present invention, it will not be described in detail. It can be of a quite conventional type, with a pump body defining an inlet with an inlet valve, a pump chamber, a piston, and an outlet valve which allows the fluid product pressurized in the pump chamber to be discharged through a hollow actuating rod 21. For fixing on the neck 12, the pump 2 is provided with a fixing ring in which the pump is fixedly received and which clings to the inside or outside of the neck 12 in a fixed and sealed manner. This is quite a classic feature for a pump and its attachment to a reservoir in the field of pharmacy, cosmetics or even perfumery. It may be noted, however, that the tank 1 defines a bore
13 qui travers l'épaisseur de paroi du réservoir et qui s'étend parallèlement à côté du col 12. La fonction de cet alésage 13 sera donnée ci-après. 13 which through the wall thickness of the reservoir and which extends parallel to the neck 12. The function of this bore 13 will be given below.
Selon l'invention, une embase 3 est montée sur la pompe 2 de manière à recueillir le produit fluide distribué par la pompe. L'embase 3 comprend un manchon de raccordement 31 qui vient en prise avec l'extrémité libre de la tige d'actionnement 21 de la pompe 2. Ce manchon 31 se prolonge par un orifice d'alimentation 32 qui débouche au fond d'une coupelle de réception 33, qui peut présenter une forme de dôme inversé. A partir de cet orifice d'alimentation 32, la coupelle 33 forme intérieurement plusieurs canaux d'alimentation 34 qui s'étendra idéalement vers l'extérieur ou en étoile à partir de l'orifice 32. Ces canaux 34 se présentent sous la forme de saignées creusées dans la paroi interne de la cavité 33. Les canaux 34 remontent sur la paroi interne de la coupelle 33 sur une certaine hauteur, par exemple jusqu'au niveau où la coupelle devient cylindrique. La fonction de ces canaux d'alimentation 34 est de répartir de manière sensiblement uniforme ou orientée le produit fluide qui est injecté à travers l'orifice d'alimentation 32 par la pompe 2. On pourrait également dire que les canaux 34 permettent de diriger le produit fluide sur la paroi interne de la coupelle 33. A son extrémité supérieure, la coupelle 33 forme une collerette annulaire 35 qui est pourvue d'une lèvre d'étanchéité 36 sur sa paroi externe. Dès à présent, on comprend que le déplacement de la coupelle de réception 3 vers le bas en direction de la pompe 2 aura pour effet d'enfoncer la tige d'actionnement 21 et ainsi engendre la distribution de produit fluide à travers la tige 21 , puis à travers l'orifice d'alimentation 32 jusque dans la cavité 33 de la coupelle. According to the invention, a base 3 is mounted on the pump 2 so as to collect the fluid dispensed by the pump. The base 3 comprises a connecting sleeve 31 which engages with the free end of the actuating rod 21 of the pump 2. This sleeve 31 is extended by a feed orifice 32 which opens at the bottom of a receiving cup 33, which may have an inverted dome shape. From this supply port 32, the cup 33 internally forms a plurality of supply channels 34 which will ideally extend outwardly or in a star shape from the orifice 32. These channels 34 are in the form of grooves hollowed in the inner wall of the cavity 33. The channels 34 back on the inner wall of the cup 33 over a certain height, for example to the level where the cup becomes cylindrical. The function of these supply channels 34 is to distribute substantially uniformly or oriented the fluid that is injected through the supply port 32 by the pump 2. It could also be said that the Channels 34 make it possible to direct the fluid product on the inner wall of the cup 33. At its upper end, the cup 33 forms an annular flange 35 which is provided with a sealing lip 36 on its outer wall. From now on, it is understood that the displacement of the receiving cup 3 down towards the pump 2 will have the effect of driving the actuating rod 21 and thus generates the distribution of fluid product through the rod 21, then through the supply port 32 into the cavity 33 of the cup.
Le distributeur comprend également une douille de guidage 5 de forme très globalement cylindrique, qui s'étend autour de l'embase 3 pour définir un fût de coulissement d'embase 54 dans lequel coulisse la lèvre d'étanchéité 36 formée par la collerette 35 de l'embase 3. Ainsi, l'embase 3 est parfaitement guidée axialement lors de son déplacement pour actionner la pompe 2. De plus, il n'y aucun risque de fuite de produit fluide autour de l'embase 3, du fait du coulissement étanche de la lèvre 36 dans le fût 54. Dans le mode de réalisation présenté pour illustrer la présente invention, la douille de guidage 5 comprend une section 51 qui s'étend autour de la pompe 2 pour venir en prise autour du col 12 du réservoir 1 . On garantit ainsi une stabilité parfaite de la douille 5 sur le réservoir 1 . A son extrémité supérieure, la douille de guidage axial 5 comprend un ou plusieurs aimants(s) 53, voire un anneau aimanté, qui s'étendent autour d'embase 3. A la place des aimants 53, on peut également prévoir un matériau ferromagnétique. On verra ci-après quelle est la fonction de cet élément aimanté ou ferromagnétique. D'autre part, la douille de guidage axial 5 forme également une canule 52 dont l'extrémité est engagée à travers l'alésage 13 du réservoir 1 . D'autre part, un conduit 37, de préférence souple, relie la coupelle 33 à la canule 52. Le conduit 37 peut par exemple déboucher dans la coupelle 33 juste au-dessus de l'extrémité supérieure des canaux d'alimentation 34. La souplesse du conduit 37 s'explique par le fait que l'embase 3 est déplaçable axialement sur une certaine course, alors que la canule 52 est fixe, puisque montée sur le réservoir 1 . Le conduit 37 et la canule 52 définissent ensemble un passage de retour de produit fluide qui relie directement l'embase 3 au réservoir de produit fluide 1 . Le conduit 37 peut par exemple passer à travers une partie ajourée 57 de la douille de guidage axial 5. The distributor also comprises a guiding sleeve 5 of very generally cylindrical shape, which extends around the base 3 to define a base sliding drum 54 in which slides the sealing lip 36 formed by the collar 35 of the base 3. Thus, the base 3 is perfectly axially guided during its movement to actuate the pump 2. In addition, there is no risk of leakage of fluid around the base 3, because of the sliding In the embodiment shown to illustrate the present invention, the guide sleeve 5 comprises a section 51 which extends around the pump 2 to engage around the neck 12 of the reservoir. 1. This guarantees a perfect stability of the bushing 5 on the tank 1. At its upper end, the axial guide sleeve 5 comprises one or more magnets 53, or even a magnetic ring, which extend around the base 3. In place of the magnets 53, a ferromagnetic material can also be provided. . We will see below what is the function of this magnetized or ferromagnetic element. On the other hand, the axial guide sleeve 5 also forms a cannula 52 whose end is engaged through the bore 13 of the reservoir 1. On the other hand, a conduit 37, preferably flexible, connects the cup 33 to the cannula 52. The conduit 37 may for example lead into the cup 33 just above the upper end of the feed channels 34. flexibility of the duct 37 is explained by the fact that the base 3 is axially displaceable over a certain stroke, whereas the cannula 52 is fixed, since mounted on the reservoir 1. The conduit 37 and the cannula 52 together define a fluid return passage which directly connects the base 3 to the fluid reservoir 1. The duct 37 may for example pass through a perforated portion 57 of the axial guide sleeve 5.
Le distributeur de l'invention comprend également un organe de préhension 4 qui est monté à la fois sur l'embase 3 et la douille de guidage axial 5. Dans ce mode de réalisation, l'organe de préhension 4 comprend un corps de préhension 40 qui définit un logement supérieur 41 et un cylindre de coulissement inférieur 42. Le logement 41 communique directement avec le cylindre 42, de sorte que le corps de préhension 40 est creux intérieurement. A son extrémité inférieure, le corps de préhension 40 comprend un ou plusieurs aimant(s) 43, voire un anneau aimanté, qui s'étend autour du cylindre de coulissement 42. A la place d'aimants, on peut également prévoir un matériau ferromagnétique. En se référant à la figure 2, on peut voir que les aimants 43 du corps de préhension 40 sont situés juste en face des aimants 53 montés sur la douille 5. Ainsi, du fait de l'attraction magnétique, l'organe de préhension 40 est connecté de manière amovible sur l'embase de réception 3 et la douille de guidage axial 5. Afin de garantir une étanchéité au niveau de l'embase 3 et de la douille 5, il est prévu un joint 44 qui entoure le cylindre de coulissement 42 et qui vient s'écraser sur la douille 5 et/ou l'embase 3. Le joint 44 peut être solidaire de l'organe de préhension 40, de la douille 5 ou encore de l'embase 3. Ces moyens de raccordement magnétiques, formés par les aimants 43 et 53, permettent non seulement un repositionnement automatique de l'organe de préhension 4, mais encore un écrasement du joint 44, et surtout d'éviter un actionnement involontaire de la pompe 2. En effet, il suffit de déposer l'organe de préhension 4 sur l'embase 3, sans exercer de force d'appui vers la pompe 2.  The dispenser of the invention also comprises a gripping member 4 which is mounted on both the base 3 and the axial guide sleeve 5. In this embodiment, the gripping member 4 comprises a gripping body 40 which defines an upper housing 41 and a lower sliding cylinder 42. The housing 41 communicates directly with the cylinder 42, so that the gripping body 40 is hollow internally. At its lower end, the gripping body 40 comprises one or more magnet (s) 43, or even a magnetic ring, which extends around the slide cylinder 42. In place of magnets, a ferromagnetic material can also be provided. . Referring to FIG. 2, it can be seen that the magnets 43 of the gripping body 40 are situated directly opposite the magnets 53 mounted on the sleeve 5. Thus, because of the magnetic attraction, the gripping member 40 is connected detachably to the receiving base 3 and the axial guide sleeve 5. In order to guarantee a seal at the base 3 and the bushing 5, there is provided a seal 44 which surrounds the sliding cylinder 42 and which collapses on the bushing 5 and / or the base 3. The seal 44 may be integral with the gripping member 40, the sleeve 5 or the base 3. These magnetic connection means formed by the magnets 43 and 53, not only allow automatic repositioning of the gripping member 4, but also a crushing of the seal 44, and especially to avoid unintentional actuation of the pump 2. Indeed, it is sufficient to deposit the gripping member 4 on the base 3, without exerting a fo support to the pump 2.
L'organe de préhension 4 comprend également un support de montage 45 pourvu d'une lèvre d'étanchéité 46 adaptée à coulisser de manière étanche dans le cylindre de coulissement 42 du corps de préhension 40. Un applicateur de produit fluide 47 est connecté à ce support de montage 45 de manière à faire saillie vers le bas à l'intérieur de la coupelle 33, comme représenté très clairement sur la figure 2. On peut remarquer que l'applicateur 47 épouse parfaitement la surface interne de coupelle 33, ou inversement : seuls les canaux d'alimentation 34 n'étant pas obturés par l'applicateur 47. On peut utiliser n'importe quel matériau approprié pour réaliser l'applicateur 47, comme par exemple un matériau poreux, en mousse, en feutre, en matériau fritté, etc. A son extrémité supérieure, le support de montage 45 est raccordé fixement à un bouton poussoir 48 qui est reçu dans le logement 41 . Le bouton poussoir 48 définit une surface d'appui S. Un ressort de rappel 49, qui prend appui à son extrémité inférieure sur le corps de montage 40, sollicite le bouton poussoir 48 en position de repos, dans laquelle il fait saillie hors du logement 41 . The gripping member 4 also comprises a mounting bracket 45 provided with a sealing lip 46 adapted to slide in a sealing manner in the sliding cylinder 42 of the gripping body 40. A fluid applicator 47 is connected to this device. mounting bracket 45 so as to project downwardly into the cup 33, as shown very clearly in FIG. note that the applicator 47 perfectly matches the inner surface of the cup 33, or vice versa: only the supply channels 34 are not closed by the applicator 47. Any suitable material can be used to make the applicator 47, such as a porous material, foam, felt, sintered material, etc. At its upper end, the mounting bracket 45 is fixedly connected to a push button 48 which is received in the housing 41. The push button 48 defines a bearing surface S. A return spring 49, which bears at its lower end on the mounting body 40, urges the push button 48 in the rest position, in which it projects out of the housing 41.
Le distributeur peut également comprendre de manière optionnelle un capot de protection 6 qui coiffe l'organe de préhension 4 et la douille de guidage axial 5.  The dispenser may also optionally comprise a protective cover 6 which covers the gripping member 4 and the axial guide sleeve 5.
L'organe de préhension 4, dans sa position de repos, est tel que représenté sur la figure 3a. Le support de montage 45 est sollicité en butée contre un épaulement formé par le corps de préhension 40. Seul l'applicateur 47 fait saillie vers le bas à partir du joint 44, lui-même entouré de l'extérieur par les aimants 43. Dans cette position de repos, l'applicateur 47 est logé dans l'embase de réception 3 sans exercer de force axiale considérable vers le bas. La pompe 2 est au repos, sa tige d'actionnement 21 est étendue au maximum. Les aimants 43, 53 sont également rapprochés au maximum, de manière à maintenir fermement, mais cependant de manière amovible, l'organe de préhension 4 sur l'embase 3 et la douille 5.  The gripping member 4, in its rest position, is as shown in Figure 3a. The mounting bracket 45 is urged against a shoulder formed by the gripping body 40. Only the applicator 47 projects downwardly from the seal 44, itself surrounded from the outside by the magnets 43. this rest position, the applicator 47 is housed in the receiving base 3 without exerting considerable axial force downwards. The pump 2 is at rest, its actuating rod 21 is extended to the maximum. The magnets 43, 53 are also brought as close together as possible, so as to firmly hold, but nevertheless removably, the gripping member 4 on the base 3 and the socket 5.
A partir de cette position de repos, l'utilisateur peut appuyer axialement vers le bas sur le bouton poussoir 48 à encontre du ressort de rappel 49 de manière à déplacer le support de montage 45 et l'applicateur 47 vers le bas. L'embase 3 est forcée de se déplacer vers le bas avec la tige d'actionnement 21 de la pompe 2. Il en résulte la distribution d'une dose de produit fluide à travers la tige d'actionnement 21 , puis à travers l'orifice d'alimentation 32 et les canaux d'alimentation 34 dans la coupelle 33 où se trouve l'applicateur 47. Celui-ci s'imprègne et se charge de produit fluide. Avantageusement, on peut dimensionner l'applicateur 47 ou la pompe 2, de sorte qu'un seul actionnement de la pompe suffit à remplir l'applicateur 47. Au cas où l'utilisateur actionne plusieurs fois le bouton poussoir 48, l'excès de produit fluide injecté dans la coupelle 33 est retourné vers le réservoir 1 à travers le conduit 37 et la canule 52. Après actionnement du bouton poussoir 48, l'utilisateur saisit l'organe de préhension 4 par son corps de préhension 40 et le sépare de la douille 5 et de la coupelle 3 en surmontant la force d'attraction magnétique exercée par les aimants 43, 53. L'applicateur 47 est alors à l'air libre et peut être mis en contact avec une surface d'application dédiée, tels que la peau, les ongles, les cheveux, etc. Une fois l'application terminée, l'utilisateur repose simplement l'organe de préhension 4 sur l'embase 3 et la douille 5 sans exercer de force de pression, les moyens de connexion magnétiques assurant à eux seuls la tenue de l'organe de préhension 4. From this rest position, the user can press axially downward on the pushbutton 48 against the return spring 49 so as to move the mounting bracket 45 and the applicator 47 downwards. The base 3 is forced to move downwards with the actuating rod 21 of the pump 2. This results in the distribution of a dose of fluid through the actuating rod 21, then through the supply port 32 and the supply channels 34 in the cup 33 where the applicator 47 is located. The latter impregnates itself and takes charge of fluid product. Advantageously, it is possible to dimension the applicator 47 or the pump 2, so that a single actuation of the pump is sufficient to fill the applicator 47. In the event that the user actuates the pushbutton 48 several times, the excess of fluid product injected into the cup 33 is returned to the reservoir 1 through the duct 37 and the cannula 52. After actuation of the push button 48, the user grasps the gripping member 4 by its gripping body 40 and separates it from the sleeve 5 and the cup 3 by overcoming the attraction force The applicator 47 is then in the open air and can be brought into contact with a dedicated application surface, such as skin, nails, hair, etc. Once the application is completed, the user simply rests the gripping member 4 on the base 3 and the sleeve 5 without exerting a pressure force, the magnetic connection means alone ensuring the holding of the organ grasping 4.
La position enfoncée du bouton poussoir 48 est représentée sur la figure 3b. On peut voir que le ressort 49 est fortement comprimé et que le support de montage 45 fait maintenant saillie vers le bas en dessous du joint 44.  The depressed position of the push button 48 is shown in Figure 3b. It can be seen that the spring 49 is strongly compressed and that the mounting bracket 45 is now projecting below the seal 44.
On se référera maintenant à la figure 4 qui montre un second mode de réalisation de l'invention. La différence principale avec le premier mode de réalisation est qu'il n'y a pas de corps de préhension dans lequel coulisse un bouton poussoir, un support de montage et l'applicateur. Dans ce second mode de réalisation plus minimaliste, l'applicateur de produit fluide 47 est monté dans un support de montage 45' qui est directement enchâssé de manière fixe dans un corps de montage 40', qui définit une surface d'appui S. Le corps de préhension 40' comprend également un ou plusieurs aimant(s) 43, voire un anneau aimanté, disposés autour du support de montage 45'. A la place de ces aimants 43, on peut également prévoir un matériau ferromagnétique. D'autre part, on peut remarquer que l'embase 3' comprend au niveau de sa collerette 35' (qui forme la lèvre de coulissement 36) un ou plusieurs aimant(s) 38, voire un anneau aimanté, ainsi qu'un joint 39. Tout comme dans le premier mode de réalisation, les aimants 43, 38, du fait de leur attraction magnétique mutuelle, permettent de comprimer le joint 39 et d'assurer l'étanchéité entre l'organe de préhension 4' et l'embase 3'. Il est à noter que la lèvre d'étanchéité 36 de l'embase 3' coulisse à l'intérieur d'un fût de coulissement 54 formé par une douille de guidage axiale 5'. Reference will now be made to FIG. 4 which shows a second embodiment of the invention. The main difference with the first embodiment is that there is no gripping body in which slides a push button, a mounting bracket and the applicator. In this second, more minimalist embodiment, the fluid applicator 47 is mounted in a mounting bracket 45 'which is directly fixedly encased in a mounting body 40', which defines a bearing surface S. gripping body 40 'also comprises one or more magnet (s) 43, or even a magnetic ring, arranged around the mounting bracket 45'. Instead of these magnets 43, it is also possible to provide a ferromagnetic material. On the other hand, it may be noted that the base 3 'comprises at its flange 35' (which forms the sliding lip 36) one or more magnet (s) 38, or even a magnetic ring, and a seal 39. As in the first embodiment, the magnets 43, 38, due to their mutual magnetic attraction, make it possible to compress the seal 39 and to seal between the gripping member 4 'and the base 3'. It should be noted that the sealing lip 36 of the base 3 'slides inside a sliding shaft 54 formed by an axial guide sleeve 5'.
Dans ce second mode de réalisation, l'organe de préhension 4' dans sa totalité est déplacé axialement pour entraîner avec lui l'embase 3' et ainsi actionner la pompe 2. Bien que non représenté, la coupelle 33 peut également être pourvue d'un passage de retour de produit fluide vers le réservoir, comme dans le premier mode de réalisation. Une fois l'applicateur 47 rempli de produit fluide, l'utilisateur sépare l'organe de préhension 4' de l'embase 3' et peut mettre l'applicateur 47 en contact avec une surface d'application appropriée.  In this second embodiment, the gripping member 4 'in its entirety is moved axially to drive with it the base 3' and thus actuate the pump 2. Although not shown, the cup 33 may also be provided with a return passage of fluid to the reservoir, as in the first embodiment. Once the applicator 47 filled with fluid product, the user separates the gripping member 4 'of the base 3' and can put the applicator 47 in contact with a suitable application surface.
L'organe de préhension 4' est un élément monobloc, à la différence de l'organe de préhension 4 du premier mode de réalisation, dans lequel le bouton poussoir 4, le support de montage 45 et l'applicateur de produit fluide 47 sont déplaçâmes par rapport au corps de préhension 40.  The gripping member 4 'is a monobloc element, unlike the gripping member 4 of the first embodiment, in which the push button 4, the mounting bracket 45 and the fluid product applicator 47 are moved. relative to the gripping body 40.
Grâce à l'invention, on dispose d'un distributeur à pompe et applicateur dont le poussoir servant à actionner la pompe est pourvu de l'applicateur de produit fluide.  Thanks to the invention, there is a pump dispenser and applicator whose pusher for actuating the pump is provided with the fluid applicator.
