Description

Distributeur de produit fluide  Fluid dispenser
La présente invention concerne un distributeur de produit fluide comprenant un réservoir de produit fluide contenant du produit fluide, une chambre d'aspiration de produit fluide de volume variable comportant un espace de prélèvement et d'application, un tube plongeur reliant le réservoir à la chambre au niveau d'un orifice, des moyens d'aspiration pour aspirer, au cours d'une phase d'aspiration, du produit fluide du réservoir dans la chambre à travers l'orifice, un organe de prélèvement et d'application qui définit partiellement la chambre d'aspiration et les moyens d'aspiration, cet organe de prélèvement et d'aspiration définissant l'espace de prélèvement et d'application. Le domaine d'application privilégié de la présente invention est celui de la parfumerie, de la cosmétique ou encore de la pharmacie. The present invention relates to a fluid dispenser comprising a fluid reservoir containing fluid, a fluid volume suction chamber having a sampling and application space, a dip tube connecting the reservoir to the chamber at an orifice, suction means for sucking, during a suction phase, the fluid product from the reservoir into the chamber through the orifice, a sampling and application member which partially defines the suction chamber and the suction means, this sampling and suction member defining the sampling and application space. The preferred field of application of the present invention is that of perfumery, cosmetics or even pharmacy.
Dans l'art antérieur, on connaît déjà le document FR-2 924 696 qui décrit un distributeur de ce type. Le fonctionnement et l'utilisation de ce distributeur sont relativement simples. L'utilisateur tient le réservoir d'une main et retire l'organe de prélèvement et d'application de l'autre main, ce qui a pour effet d'aspirer du produit fluide dans la chambre de dosage à travers le tube plongeur relié au réservoir. Le remplissage de la chambre de dosage permet également le remplissage de l'espace de prélèvement et d'application qui est solidaire de l'applicateur de produit fluide. Il faut noter que le volume de cet espace est fixe et constant : il ne subit aucune déformation ou modification. Lorsque l'applicateur de produit fluide est totalement retiré du réservoir, il en est séparé, la chambre de dosage est ouverte sur l'extérieur et l'espace de prélèvement, qui est solidaire de l'applicateur de produit fluide, peut être mise en contact avec une surface d'application, telle que la peau de l'utilisateur. L'application proprement dite du produit fluide s'effectue soit par contact ponctuel successif avec la peau, soit en déplaçant la zone de prélèvement en contact avec la peau. Dans les deux cas, le produit fluide stocké dans l'espace de prélèvement est progressivement transféré par un phénomène de tension superficielle sur la peau de l'utilisateur. Bien entendu, pour permettre un tel transfert de l'espace de prélèvement à la surface d'application de l'utilisateur, il est nécessaire que le produit fluide présente une viscosité relativement faible. En effet, avec un produit de plus grande viscosité, tel qu'une crème ou un gel, celui-ci resterait adhéré aux parois internes de l'espace de prélèvement de sorte qu'une partie limitée du produit pourrait être appliquée sur la surface d'application. Par conséquent, le distributeur du document FR-2 924 696, qui présente un espace de prélèvement de volume fixe et constant, n'est pas adapté à la distribution de produits fluides visqueux tels que des crèmes, des gels, des pommades, etc. In the prior art, document FR-2 924 696 describes a distributor of this type. The operation and use of this dispenser are relatively simple. The user holds the tank with one hand and removes the sampling and application member with the other hand, which has the effect of drawing fluid in the metering chamber through the dip tube connected to the tank. The filling of the metering chamber also allows the filling of the sampling and application space which is integral with the fluid applicator. It should be noted that the volume of this space is fixed and constant: it undergoes no deformation or modification. When the fluid applicator is completely removed from the reservoir, it is separated from it, the metering chamber is open to the outside and the sampling space, which is integral with the fluid applicator, can be contact with an application surface, such as the skin of the user. The actual application of the fluid product is carried out either by successive point contact with the skin, or by moving the sampling zone in contact with the skin. In both cases, the fluid product stored in the sampling space is progressively transferred by a phenomenon of surface tension on the skin of the user. Of course, to allow such a transfer of the sampling space to the application surface of the user, it is necessary that the fluid has a relatively low viscosity. Indeed, with a product of higher viscosity, such as a cream or a gel, it would remain adhered to the internal walls of the sampling space so that a limited portion of the product could be applied to the surface of the sample. 'application. Consequently, the dispenser of document FR-2 924 696, which has a fixed and constant volume sampling space, is not suitable for dispensing viscous fluids such as creams, gels, ointments, etc.
La présente invention a pour but de remédier aux inconvénients précités du document de l'art antérieur en définissant un distributeur de produit fluide basé sur le même principe mais permettant une application de produit fluide visqueux. Un but de la présente invention est de garantir à la fois un remplissage total de l'espace de prélèvement lors du retrait de l'applicateur et un vidage total de l'espace de prélèvement lors de l'application du produit fluide sur la surface d'application. Un autre but de la présente invention est de conserver une structure et une architecture particulièrement simple du distributeur de produit fluide. Encore un autre but de la présente invention est de conserver la gestuelle d'utilisation du distributeur de produit fluide de l'art antérieur. Encore un autre but de la présente invention est d'éviter l'utilisation de matériau non recyclable, tel que du métal.  The present invention aims to overcome the aforementioned drawbacks of the document of the prior art by defining a fluid dispenser based on the same principle but allowing application of viscous fluid product. An object of the present invention is to ensure both a total filling of the sampling space during removal of the applicator and a total emptying of the sampling space during the application of the fluid product on the surface of the 'application. Another object of the present invention is to maintain a particularly simple structure and architecture of the fluid dispenser. Yet another object of the present invention is to preserve the gesture of use of the fluid dispenser of the prior art. Yet another object of the present invention is to avoid the use of non-recyclable material, such as metal.
Pour atteindre ces différents buts, la présente invention propose un distributeur de produit fluide comprenant un réservoir de produit fluide contenant du produit fluide, une chambre d'aspiration de produit fluide de volume variable comportant un espace de prélèvement et d'application présentant un volume variable entre un volume minimal lorsque la chambre d'aspiration présente un volume minimal et un volume maximal lorsque la chambre d'aspiration présente un volume maximal, un tube plongeur reliant le réservoir à la chambre d'aspiration au niveau d'un orifice, des moyens d'aspiration pour aspirer, au cours d'une phase d'aspiration, du produit fluide du réservoir dans la chambre à travers l'orifice, un organe de prélèvement et d'application qui définit partiellement la chambre d'aspiration et les moyens d'aspiration, cet organe de prélèvement et d'aspiration définissant l'espace de prélèvement et d'application, le coulissement du manchon coulissant sur la tige fixe étant exempt de force de sollicitation élastique. Ainsi, le distributeur peut être réalisé à partir d'élément en matière plastique moulé, à l'exclusion de tout élément métallique. La variation du volume de l'espace de prélèvement et d'application permet d'une part de faciliter son remplissage en démultipliant les moyens d'aspiration et d'autre part de le vider progressivement à mesure que le produit fluide est appliqué sur la surface d'application. Ceci n'est pas le cas dans le document de l'art antérieur précité dont l'espace de prélèvement présente un volume fixe. Du fait de l'absence de force de sollicitation élastique sur le manchon, l'application du produit fluide, par exemple sur la peau, s'effectue sans avoir à surmonter une résistance élastique, ce qui se traduit par un contact plus doux et agréable au niveau de la peau. To achieve these different aims, the present invention provides a fluid dispenser comprising a fluid reservoir containing fluid product, a fluid volume suction chamber of variable volume having a sampling and application space having a variable volume between a minimum volume when the suction chamber has a minimum volume and a maximum volume when the suction chamber has a maximum volume, a dip tube connecting the reservoir to the suction chamber at an orifice, means for sucking, during a suction phase, the fluid product of the reservoir in the chamber through the orifice, a sampling and application member which partially defines the suction chamber and the suction means, this sampling and suction member defining the sampling and sampling space. application, the sliding sleeve sliding on the fixed shaft being free of elastic biasing force. Thus, the dispenser can be made from molded plastic element, excluding any metal element. The variation of the volume of the sampling and application space makes it possible on the one hand to facilitate its filling by multiplying the suction means and on the other hand to empty it gradually as the fluid product is applied to the surface. application. This is not the case in the document of the aforementioned prior art whose sampling space has a fixed volume. Due to the absence of elastic biasing force on the sleeve, the application of the fluid product, for example on the skin, is carried out without having to overcome an elastic resistance, which results in a softer and pleasant contact at the level of the skin.
Avantageusement, l'espace de prélèvement et d'application comprend une extrémité ouverte d'application communiquant avec le reste de la chambre d'aspiration et une extrémité fermée, les extrémités ouverte et fermée étant déplaçables l'une par rapport à l'autre. Le déplacement relatif des deux extrémités de l'espace de prélèvement et d'application peut se faire de diverses manières, comme par coulissement à la manière d'un piston ou encore par déformation élastique d'un élément souple.  Advantageously, the sampling and application space comprises an open application end communicating with the remainder of the suction chamber and a closed end, the open and closed ends being movable relative to one another. The relative displacement of the two ends of the sampling and application space can be done in various ways, such as sliding in the manner of a piston or by elastic deformation of a flexible element.
Selon une forme de réalisation pratique, l'organe de prélèvement et d'application comprend un élément de préhension manuelle destiné à être saisi par la main d'un utilisateur, une tige fixe solidaire de l'élément de préhension et un manchon coulissant qui est monté de manière coulissante sur la tige fixe pour former l'espace de prélèvement et d'application de volume variable. Ainsi, la tige fixe remplit une fonction de piston qui se déplace de manière étanche à l'intérieur d'un fût de coulissement défini par le manchon coulissant. Avantageusement, le manchon coulissant forme l'extrémité ouverte d'application de l'espace de prélèvement et d'application et la tige fixe forme l'extrémité fermée de l'espace de prélèvement et d'application. L'extrémité ouverte d'application du manchon peut se présenter sous la forme d'un bord annulaire destiné à venir en contact avec la surface d'application, alors que l'extrémité fermée de la tige fixe peut se présenter sous la forme de l'extrémité libre de la tige fixe qui présente un pourtour correspondant à celui de l'extrémité ouverte d'application. According to a practical embodiment, the sampling and application member comprises a manual gripping element intended to be grasped by the hand of a user, a fixed rod secured to the gripping element and a sliding sleeve which is slidably mounted on the fixed shaft to form the sampling and application space of variable volume. Thus, the fixed rod performs a piston function which moves in a sealed manner within a sliding shaft defined by the sliding sleeve. Advantageously, the sliding sleeve forms the open end of application of the sampling and application space and the stationary rod forms the closed end of the sampling and application space. The open end of application of the sleeve may be in the form of an annular edge intended to come into contact with the application surface, while the closed end of the fixed rod may be in the form of the free end of the fixed rod which has a perimeter corresponding to that of the open end of application.
Selon un autre aspect de l'invention, le manchon coulisse en outre dans une lèvre fixe solidaire du réservoir pour définir les moyens d'aspiration. Ainsi, le manchon coulissant est mobile à la fois par rapport à la tige fixe et par rapport à la lèvre fixe du réservoir. La tige fixe remplit une fonction de piston à l'intérieur du manchon pour définir l'espace de prélèvement et d'application et le manchon coulissant remplit une fonction de piston en coulissant de manière étanche à l'intérieur de la lèvre fixe pour définir les moyens d'aspiration et la chambre de d'aspiration de produit fluide.  According to another aspect of the invention, the sleeve slides further in a fixed lip integral with the reservoir to define the suction means. Thus, the sliding sleeve is movable both with respect to the fixed rod and relative to the fixed lip of the tank. The fixed shaft performs a piston function within the sleeve to define the sample and application space, and the slide sleeve performs a piston function by sealingly sliding within the fixed lip to define suction means and the fluid suction chamber.
Selon une autre caractéristique intéressante de l'invention, le manchon coulisse sur la tige fixe avec des forces de frottement qui sont inférieures à celles des moyens d'aspiration. Ainsi, lorsque l'on retire l'organe de prélèvement et d'application du réservoir, le manchon coulissant reste fixe par rapport à la lèvre fixe alors que la tige fixe se déplace à l'intérieur du manchon coulissant de manière à augmenter le volume de l'espace de prélèvement et d'application. Ensuite, lorsque l'espace de prélèvement et d'application a atteint son volume maximal, le manchon coulissant commence à coulisser dans la lèvre fixe de manière à augmenter encore davantage le volume de la chambre de d'aspiration de produit fluide.  According to another advantageous characteristic of the invention, the sleeve slides on the fixed rod with friction forces which are lower than those of the suction means. Thus, when the withdrawal and application member of the reservoir is removed, the sliding sleeve remains fixed relative to the fixed lip while the fixed rod moves inside the sliding sleeve so as to increase the volume. sampling and application space. Then, when the sampling and application space has reached its maximum volume, the sliding sleeve begins to slide into the fixed lip so as to further increase the volume of the fluid suction chamber.
Selon un autre aspect intéressant de l'invention, le manchon coulissant est en butée contre la tige fixe lorsque l'espace de prélèvement et d'application présente un volume maximal. Cette butée entre le manchon coulissant et la tige fixe définit bien entendu le volume maximal de prélèvement et d'application, mais marque également le début du coulissement du manchon coulissant à l'intérieur de la lèvre fixe solidaire du réservoir. Selon une autre caractéristique avantageuse, le manchon coulissant est en butée contre la tige fixe et/ou l'élément de préhension lorsque l'espace de prélèvement et d'application présente un volume minimal. Selon un mode de montage du distributeur, le manchon coulissant est engagé autour de la tige fixe avant que la tige fixe soit raccordée fixement à l'élément de préhension. Ainsi, le manchon coulissant ne peut en aucun cas se désengager de la tige fixe de sorte que l'organe de prélèvement et d'application constitue une entité solidaire imperdable. According to another interesting aspect of the invention, the sliding sleeve is in abutment against the fixed rod when the sampling and application space has a maximum volume. This stop between the sliding sleeve and the fixed rod of course defines the maximum volume of sampling and application, but also marks the beginning of the sliding of the sleeve sliding inside the fixed lip secured to the reservoir. According to another advantageous characteristic, the sliding sleeve is in abutment against the fixed rod and / or the gripping element when the sampling and application space has a minimum volume. According to a mounting mode of the dispenser, the sliding sleeve is engaged around the fixed rod before the fixed rod is fixedly connected to the gripping element. Thus, the sliding sleeve can in no case disengage from the fixed rod so that the sampling and application member is a captive integral entity.
Tout comme dans le document de l'art antérieur précité, la chambre d'aspiration est ouverte vers l'extérieur lorsque l'organe de prélèvement et d'application est séparé du réservoir. D'autre part, la chambre d'aspiration comprend un fût auquel se raccorde le tube plongeur, le fût étant pourvu d'une lèvre de coulissement étanche destinée à coopérer avec l'organe de prélèvement et d'application pour former les moyens d'aspiration.  As in the document of the aforementioned prior art, the suction chamber is open to the outside when the sampling and application member is separated from the reservoir. On the other hand, the suction chamber comprises a barrel to which the plunger tube is connected, the barrel being provided with a sealed sliding lip intended to cooperate with the sampling and application member to form the means for aspiration.
L'esprit de l'invention réside dans le fait de faire varier le volume de l'espace de prélèvement et d'application au cours de sa phase de remplissage, mais également au cours de la phase d'application du produit fluide sur une surface d'application souhaitée. Pour cela, le volume de l'espace de prélèvement et d'application croît progressivement à mesure que l'on retire l'espace de prélèvement et d'application du réservoir et décroît progressivement à mesure que l'on applique le produit fluide sur la surface d'application souhaitée. L'espace de prélèvement et d'application agit ainsi à la manière d'une chambre de pompe, qui est elle-même incluse dans une chambre d'aspiration reliée au réservoir par un tube plongeur. L'augmentation de volume de l'espace de prélèvement et d'application peut se faire avant l'augmentation de volume du reste de la chambre d'aspiration, ou après l'augmentation de volume du reste de la chambre d'aspiration, ou en même temps.  The spirit of the invention lies in the fact of varying the volume of the sampling and application space during its filling phase, but also during the application phase of the fluid product on a surface desired application. For this purpose, the volume of the sampling and application space grows progressively as the sampling and application space of the reservoir is withdrawn and decreases progressively as the fluid is applied to the reservoir. desired surface of application. The sampling and application space thus acts in the manner of a pump chamber, which is itself included in a suction chamber connected to the reservoir by a dip tube. The volume increase of the sampling and application space can be done before the volume increase of the rest of the suction chamber, or after the increase in volume of the remainder of the suction chamber, or at the same time.
L'invention sera maintenant plus amplement décrite en référence aux dessins joints, donnant à titre d'exemple non limitatif, un mode de réalisation de l'invention.  The invention will now be further described with reference to the accompanying drawings, giving by way of non-limiting example, an embodiment of the invention.

On se référera tout d'abord aux figures 1 à 3 pour décrire en détail un mode de réalisation non limitatif pour un distributeur de produit fluide selon l'invention. Le distributeur comprend de manière très globale un réservoir de produit fluide 1 auquel est associé un organe de distribution selon l'invention. Le réservoir 1 n'est pas critique pour la présente invention, et peut donc présenter des caractéristiques très diverses. Il peut être réalisé en n'importe quel matériau comme par exemple du verre, du plastique, du métal, etc. et présenter des formes très variées. De manière très classique, le réservoir comprend un corps volumineux, dans lequel le produit fluide est stocké, ainsi qu'un col 1 1 qui définit une ouverture qui fait communiquer l'intérieur du corps avec l'extérieur. L'organe de distribution de l'invention est monté de manière fixe, et de préférence définitive, sur le col 1 1 du réservoir de manière à pouvoir prélever du produit fluide.  Referring first to Figures 1 to 3 to describe in detail a non-limiting embodiment for a fluid dispenser according to the invention. The dispenser comprises in a very comprehensive manner a fluid reservoir 1 which is associated with a dispensing member according to the invention. The tank 1 is not critical for the present invention, and can therefore have very diverse characteristics. It can be made of any material such as glass, plastic, metal, etc. and present very varied forms. In a very conventional manner, the reservoir comprises a bulky body, in which the fluid product is stored, and a neck 1 1 which defines an opening which communicates the interior of the body with the outside. The dispensing member of the invention is mounted fixedly, and preferably permanently, on the neck 1 1 of the tank so as to take fluid product.
L'organe de distribution de la présente invention comprend deux sous- ensembles bien distincts, à savoir un premier sous-ensemble solidaire du réservoir, et un second sous-ensemble formant un organe de prélèvement et d'application P qui peut être séparé du premier sous-ensemble. Dans le mode de réalisation des figures, le premier sous-ensemble solidaire du réservoir comprend une bague 2 montée sur et dans le col 1 1 du réservoir de manière étanche fixe et de préférence définitive. La bague 2 coopère avec une couronne d'étanchéité 3, un joint de col 4 et une frette de blocage et d'habillage 5. Ces quatre éléments constitutifs 2, 3, 4 et 5 constituent le premier sous-ensemble qui est monté de manière fixe sur le réservoir 1 . Le second sous-ensemble formant l'organe de prélèvement et d'application P comprend un élément de préhension 6 destiné à être saisi manuellement par l'utilisateur, une tige fixe 7 solidaire de l'élément de préhension 6 et un manchon coulissant 8 qui est engagé de manière déplaçable par coulissement autour de la tige fixe 7. The dispensing member of the present invention comprises two distinct subsets, namely a first integral subassembly of the tank, and a second subassembly forming a sampling and application member P which can be separated from the first one. subset. In the embodiment of the figures, the first integral subassembly of the reservoir comprises a ring 2 mounted on and in the neck 1 1 of the tank in a fixed and preferably permanent sealed manner. The ring 2 cooperates with a sealing ring 3, a neck gasket 4 and a locking and cladding ring 5. These four constituent elements 2, 3, 4 and 5 constitute the first subassembly which is mounted so that fixed on the tank 1. The second subassembly forming the sampling and application member P comprises a gripping element 6 intended to be manually gripped by the user, a fixed rod 7 integral with the gripping element 6 and a sliding sleeve 8 which is displaceably engaged by sliding around the fixed rod 7.
La bague 2 comprend un fût de coulissement cylindrique 21 qui forme à son extrémité inférieure un orifice 22 qui communique avec un manchon de raccordement 23 dans lequel est engagé un tube plongeur 24. En variante non représenté, le tube plongeur 24 peut être réalisé de manière monobloc avec le manchon de raccordement 23. A son extrémité opposée, le fût 21 se prolonge par une collerette 25 qui est filetée extérieurement. Intérieurement, la collerette 25 sert de support pour la couronne d'étanchéité 3 qui définit à son extrémité inférieure libre une lèvre d'étanchéité 31 dont la fonction sera donnée ci-après. La collerette 25 se prolonge radialement vers l'extérieur en formant un plateau qui se raccorde à une jupe d'accrochage 26 en prise avec le col 1 1 du réservoir 1 . Cette jupe 26 peut par exemple être réalisée sous la forme de plusieurs pattes séparées par des fentes, chaque patte formant une ou plusieurs tête(s) d'accrochage destinée(s) à venir en prise sous un renfort annulaire formé par le col 1 1 . Il s'agit là d'une caractéristique tout à fait classique pour la fixation d'un organe de distribution sur un col de réservoir. The ring 2 comprises a cylindrical sliding shaft 21 which forms at its lower end an orifice 22 which communicates with a connecting sleeve 23 in which is engaged a dip tube 24. In a variant not shown, the dip tube 24 can be made in a in one piece with the connecting sleeve 23. At its opposite end, the barrel 21 is extended by a flange 25 which is threaded externally. Internally, the flange 25 serves as a support for the sealing ring 3 which defines at its lower free end a sealing lip 31 whose function will be given below. The flange 25 extends radially outwardly forming a plate which is connected to a hooking skirt 26 in engagement with the neck 1 1 of the tank 1. This skirt 26 may for example be made in the form of several tabs separated by slots, each tab forming one or more attachment head (s) intended (s) to come into engagement under an annular reinforcement formed by the neck 1 1 . This is a characteristic quite conventional for fixing a dispensing member on a tank neck.
Pour maintenir la jupe d'accrochage 26 en prise avec le col, il est courant de se servir d'une frette de blocage et d'habillage 5 qui se présente sous la forme d'un cylindre qui est engagé autour de la jupe de manière serrante. Là encore, il s'agit d'une caractéristique tout à fait classique pour fixer une jupe autour d'un col. Ce faisant, le joint de col 4 est écrasé par la bague sur le bord annulaire supérieur du col 1 1 . Il s'agit à nouveau d'une caractéristique tout à fait classique. La couronne d'étanchéité 3 peut être simplement rapportée dans la collerette 25, ou de préférence la couronne d'étanchéité 3 peut être surmoulée dans la collerette 25. La couronne d'étanchéité 3 peut être réalisée en un matériau élastomère de manière à conférer une certaine élasticité à la lèvre d'étanchéité 31 . Bien que non représenté, il est possible de réaliser la couronne d'étanchéité 3 de manière monobloc avec la bague 2. Il est également possible de se passer du joint d'étanchéité 4. Bien que non représenté, il est également possible de se passer de la frette 5 en prévoyant une jupe 26 suffisamment solide pour assurer à elle seule le montage de la bague sur le col 1 1 . Il est également possible de prévoir une jupe 26 qui coopère avec l'intérieur du col 1 1 , et non pas avec l'extérieur comme représenté sur les figures. To maintain the hooking skirt 26 in engagement with the neck, it is customary to use a locking and wrapping band 5 which is in the form of a cylinder which is engaged around the skirt in such a way that clasping. Again, this is a quite classic feature for attaching a skirt around a collar. In doing so, the neck seal 4 is crushed by the ring on the upper annular edge of the neck 1 January. This is again a classic feature. The sealing ring 3 can simply be attached to the flange 25, or preferably the sealing ring 3 can be overmolded in the flange 25. The sealing ring 3 can be made of an elastomeric material so as to impart a certain elasticity at the sealing lip 31. Although not shown, it is possible to make the sealing ring 3 integrally with the ring 2. It is also possible to dispense with the seal 4. Although not shown, it is also possible to do without of the hoop 5 by providing a skirt 26 sufficiently strong to ensure alone the mounting of the ring on the neck 1 1. It is also possible to provide a skirt 26 which cooperates with the inside of the neck 1 1, and not with the outside as shown in the figures.
Lorsque la bague 2 est ainsi monté sur le col 1 1 du réservoir, le fût de coulissement 25 s'étend à l'intérieur du col 1 1 et le tube plongeur 24 s'étend dans le réservoir jusqu'à proximité de son fond (non représenté). A l'extrémité opposée, le fût 21 est largement ouvert avec sa couronne d'étanchéité 3. Le col n'est plus visible, étant donné qu'il est masqué à la fois par la jupe d'accrochage 26 et la frette de blocage et d'habillage 5.  When the ring 2 is thus mounted on the neck 1 1 of the reservoir, the sliding shaft 25 extends inside the neck 1 1 and the dip tube 24 extends into the reservoir to near its bottom ( not shown). At the opposite end, the barrel 21 is widely open with its sealing ring 3. The collar is no longer visible, since it is masked both by the attachment skirt 26 and the locking collar and dressing 5.
L'organe de prélèvement et d'application P est destiné à coopérer avec le premier sous-ensemble, et notamment avec la bague 2 et la couronne d'étanchéité 3.  The sampling and application member P is intended to cooperate with the first subassembly, and in particular with the ring 2 and the sealing ring 3.
L'élément de préhension 6 définit un appendice de préhension 61 qui est destiné à être saisi directement par les doigts de l'utilisateur. Cet appendice de préhension 61 peut présenter les formes les plus diverses et de préférence ergonomiques pour faciliter sa préhension. L'élément de préhension 6 définit intérieurement un alésage borgne 63 qui est entouré de manière concentrique par une gorge annulaire 65. L'alésage borgne 63 est séparé de cette gorge annulaire 65 par une petite tubulure 64. A son extrémité inférieure, l'élément de préhension 6 définit un filetage interne 62 destiné à coopérer avec la collerette filetée 25 de la bague 2.  The gripping element 6 defines a gripping appendage 61 which is intended to be grasped directly by the fingers of the user. This gripping appendix 61 may have the most diverse forms and preferably ergonomic to facilitate its grip. The gripping element 6 defines internally a blind bore 63 which is concentrically surrounded by an annular groove 65. The blind bore 63 is separated from this annular groove 65 by a small pipe 64. At its lower end, the element gripper 6 defines an internal thread 62 intended to cooperate with the threaded collar 25 of the ring 2.
La tige fixe 7 comprend une broche d'ancrage 71 engagée de manière fixe et de préférence définitive à l'intérieur de l'alésage borgne 63 de l'élément de préhension 6. La tige fixe 7 définit également une section de guidage 73 qui se raccorde à la broche d'ancrage 71 en formant un épaulement annulaire 72. Dans sa partie inférieure, la section de guidage 73 forme une butée 74, un segment de piston 75 et définit une extrémité inférieure 76. On peut remarquer que l'épaulement 72 vient en contact de l'extrémité libre de la petite tubulure 64 lorsque la broche d'ancrage 71 est engagée à fond dans l'alésage borgne 63. La section de guidage 73 fait largement saillie vers le bas au-delà du filetage interne 62 de l'élément de préhension 6. The fixed rod 7 comprises an anchor pin 71 fixedly and preferably permanently engaged inside the blind bore 63 of the gripping element 6. The fixed rod 7 also defines a guiding section 73 which connects to the anchoring pin 71 by forming an annular shoulder 72. In its lower part, the guiding section 73 forms a stop 74, a piston ring 75 and defines a lower end 76. It may be noted that the shoulder 72 comes into contact with the free end of the small pipe 64 when the anchor pin 71 is fully engaged in the blind bore 63 The guiding section 73 is largely projecting downwardly beyond the internal thread 62 of the gripping element 6.
Le manchon coulissant 8 est engagé autour de la tige fixe 7, et plus précisément autour de la section de guidage 73. Le manchon coulissant 8 comprend une embase annulaire 81 qui est engagée à l'intérieur de la gorge annulaire 65. Sur les figures 1 et 2, on peut voir que l'embase annulaire 81 vient même en butée contre le fond de la gorge annulaire 65. Au-delà de cette embase annulaire 81 , le manchon coulissant 8 forme un épaulement rentrant 82 qui vient en butée contre l'extrémité libre de la petite tubulure 64. Au-delà de cet épaulement rentrant 82, le manchon coulissant 8 forme un segment de guidage 83 qui coulisse avec un ajustement réduit avec la section de guidage 73 de la tige fixe 7. Au-delà de ce segment de guidage 83, le manchon 8 forme un autre épaulement 84 à partir duquel le manchon définit une section de coulissement étanche 85 qui se termine par une extrémité inférieure ouverte d'application 86. Sur les figures 1 et 2, on peut voir que l'extrémité inférieure 76 de la tige fixe 7 est alignée avec l'extrémité inférieure d'application 86 du manchon 8. On peut également remarquer que le segment de piston 75 est en contact étanche à l'intérieur de la section de coulissement 85. On peut également voir que l'épaulement 84 est en éloignement de la butée 74. Selon l'invention, le manchon coulissant 8 peut se déplacer par coulissement étanche le long de la tige fixe 7 entre deux positions extrêmes de butée, à savoir celle représentée sur les figures 1 et 2 et une autre extrémité de butée définie lorsque l'épaulement 84 est en butée contre la butée 74. On peut noter que la configuration de l'élément de préhension 6, de la tige fixe 7 et du manchon coulissant 8 est telle qu'il est possible de les assembler en engageant tout d'abord le manchon 8 autour de la tige 7 et en engageant ensuite la tige 7 dans l'élément de préhension 6. Ainsi, il n'est pas nécessaire de mettre en place le manchon 8 sur la tige 7 par force ou par déformation élastique. De plus, l'organe de préhension et d'application P constitue une unité solidaire dans laquelle le manchon 8 n'est plus séparable. The sliding sleeve 8 is engaged around the fixed rod 7, and more precisely around the guide section 73. The sliding sleeve 8 comprises an annular base 81 which is engaged inside the annular groove 65. In FIGS. and 2, it can be seen that the annular base 81 even abuts against the bottom of the annular groove 65. Beyond this annular base 81, the sliding sleeve 8 forms a reentrant shoulder 82 which abuts against the free end of the small tubing 64. Beyond this recessed shoulder 82, the sliding sleeve 8 forms a guide segment 83 which slides with a reduced fit with the guide section 73 of the fixed rod 7. Beyond this guide segment 83, the sleeve 8 forms another shoulder 84 from which the sleeve defines a sealed sliding section 85 which terminates in an open bottom application end 86. In FIGS. 1 and 2, it can be seen that 'extrémit The lower rod 76 of the fixed rod 7 is aligned with the lower application end 86 of the sleeve 8. It may also be noted that the piston ring 75 is in leaktight contact inside the sliding section 85. also see that the shoulder 84 is away from the stop 74. According to the invention, the sliding sleeve 8 can move by leaktight sliding along the fixed rod 7 between two extreme stop positions, namely that represented on the FIGS. 1 and 2 and another stop end defined when the shoulder 84 is in abutment with the abutment 74. It may be noted that the configuration of the gripping element 6, the fixed rod 7 and the sliding sleeve 8 is such that it is possible to assemble them by first engaging the sleeve 8 around the rod 7 and then engaging the rod 7 in the gripping member 6. Thus, it is not necessary to place the sleeve 8 on the rod 7 by force or by elastic deformation. In addition, the gripping member and application P is a unitary unit in which the sleeve 8 is no longer separable.
Sur la figure 1 , on peut voir que l'organe de prélèvement et d'application P est monté sur la bague 2. Le filetage 62 de l'élément de préhension 6 est vissé à fond sur la collerette filetée 25 de la bague 2. Le manchon coulissant 8 est engagé à l'intérieur du fût 21 en définissant un contact annulaire étanche avec la lèvre d'étanchéité 31 de la couronne 3. Ainsi, une chambre d'aspiration C est formée entre le fût 21 , le manchon 8 et la tige fixe 7. Cette chambre d'aspiration C communique avec le réservoir 1 à travers l'orifice 22 et le tube plongeur 24. Sur les figures 1 et 2, cette chambre d'aspiration C définit un volume minimal. La configuration représentée sur les figures 1 et 2 constitue la position de repos et de stockage du distributeur.  In FIG. 1, it can be seen that the sampling and application member P is mounted on the ring 2. The threading 62 of the gripping element 6 is screwed fully onto the threaded collar 25 of the ring 2. The sliding sleeve 8 is engaged inside the barrel 21 by defining an annular sealing contact with the sealing lip 31 of the ring 3. Thus, a suction chamber C is formed between the barrel 21, the sleeve 8 and the fixed rod 7. This suction chamber C communicates with the reservoir 1 through the orifice 22 and the dip tube 24. In Figures 1 and 2, this suction chamber C defines a minimum volume. The configuration shown in Figures 1 and 2 constitutes the rest position and storage of the dispenser.
On se référera maintenant aux figures 4a à 4d pour décrire un premier cycle opératoire de retrait de l'organe de prélèvement et d'application P. sur la figure 4a, l'élément de préhension 6 a déjà été dévissé de la collerette filetée 25, ce qui a généré un déplacement translatif coulissant entre la tige fixe 7 et le manchon coulissant 8. Plus précisément, le manchon coulissant 8 est resté en place par rapport au fût 21 , alors que la tige fixe 7 s'est déplacée à l'intérieur du manchon coulissant 8. Ceci est rendu possible étant donné que les forces de frottement entre la lèvre 31 et le manchon 8 sont supérieures à celles entre le manchon 8 et la tige fixe 7. Avec ce déplacement translatif relatif, un espace de prélèvement et d'application E a été créé à l'intérieur du manchon 8 juste au-dessus de la tige 7. Cet espace de prélèvement et d'application E fait partie intégrante de la chambre d'aspiration C, étant donné que cet espace E communique directement avec la chambre C au niveau de l'extrémité ouverte d'application 86 du manchon 8. Sur la figure 4b, l'élément de préhension 6 a encore davantage été retiré, ce qui a amené une augmentation supplémentaire du volume de l'espace de prélèvement et d'application E. On peut remarquer que le manchon 8 est toujours statique par rapport au fût 21 . Sur la figure 4b, l'espace de prélèvement et d'application E a atteint son volume maximal correspondant à la mise en butée de l'épaulement 84 avec la butée 74. A partir de ce moment, une traction supplémentaire sur l'élément de préhension 6 entraîne un coulissement du manchon 8 à l'intérieur du fût 21 . Ceci est représenté sur la figure 4c. Même si l'espace de prélèvement et d'application E n'augmente plus en volume, la chambre d'aspiration C augmente de volume du fait du déplacement du manchon 8. L'augmentation du volume de la chambre d'aspiration C se poursuit jusqu'à ce que l'extrémité inférieure du manchon 8 quitte son contact avec la lèvre 31 , ce qui est représenté sur la figure 4d. La chambre d'aspiration C est alors ouverte sur l'extérieur. L'espace de prélèvement et d'application E reste cependant rempli de produit fluide par un phénomène de capillarité, de viscosité et de tension superficielle. Reference will now be made to FIGS. 4a to 4d to describe a first operating cycle of withdrawal of the sampling and application member P. In FIG. 4a, the gripping element 6 has already been unscrewed from the threaded flange 25, this has generated a sliding translational movement between the fixed rod 7 and the sliding sleeve 8. More specifically, the sliding sleeve 8 has remained in place relative to the barrel 21, while the fixed rod 7 has moved inside. This is made possible because the frictional forces between the lip 31 and the sleeve 8 are greater than those between the sleeve 8 and the fixed rod 7. With this relative translational movement, a sampling space and Application E has been created inside the sleeve 8 just above the rod 7. This sampling and application space E is an integral part of the suction chamber C, since this space E communicated that directly with the chamber C at the open application end 86 of the sleeve 8. In FIG. 4b, the gripping element 6 has been further removed, which has led to a further increase in the volume of the sampling space. and application E. It can be noted that the sleeve 8 is still static with respect to the barrel 21. In FIG. 4b, the sampling and application space E has reached its maximum volume corresponding to the abutment of the shoulder 84 with the abutment 74. From this moment, additional traction on the element gripping 6 causes a sliding of the sleeve 8 inside the barrel 21. This is shown in Figure 4c. Even if the sampling and application space E no longer increases in volume, the suction chamber C increases in size due to the displacement of the sleeve 8. The increase in the volume of the suction chamber C continues until the lower end of the sleeve 8 leaves its contact with the lip 31, which is shown in Figure 4d. The suction chamber C is then open on the outside. The sampling and application space E remains, however, filled with fluid product by a phenomenon of capillarity, viscosity and surface tension.
Au cours de l'augmentation de volume de l'espace de prélèvement et d'application E et de la chambre d'aspiration C, du produit fluide en provenance du réservoir a été aspiré à l'intérieur de l'espace E et de la chambre C à travers le tube plongeur 24. La coopération du manchon 8 avec la lèvre d'étanchéité 31 constitue des moyens d'aspiration permettant au produit fluide du réservoir de remonter à travers le tube plongeur 24. N'importe quel produit fluide peut être conditionné dans le distributeur de la présente invention, mais une application privilégiée est trouvée avec les produits visqueux, comme les crèmes, les gels, les pommades, etc. En effet, le déplacement relatif du manchon 8 par rapport à la tige 7 permet de faire varier le volume de l'espace de prélèvement et d'application E et de créer un effet de pistonnage qui permet d'aspirer le produit fluide à l'intérieur de l'espace E. Alors que le volume de l'espace E est nul sur la figure 1 , il augmente progressivement comme on peut le voir à travers les figures 4a à 4d pour parvenir finalement à un volume maximal. On peut encore dire que l'espace de prélèvement et d'application E définit une extrémité ouverte d'application constituée par l'extrémité inférieure 86 du manchon 8 et une extrémité fermée constituée par l'extrémité inférieure 76 de la tige 7. Ces deux extrémités se déplacent l'une par rapport à l'autre de manière à faire varier le volume de l'espace E. During the increase in volume of the sampling and application space E and the suction chamber C, the fluid product from the reservoir was sucked into the space E and the Chamber C through the dip tube 24. The cooperation of the sleeve 8 with the sealing lip 31 constitutes suction means allowing the fluid product of the tank to go up through the dip tube 24. Any fluid product may be packaged in the dispenser of the present invention, but a preferred application is found with viscous products, such as creams, gels, ointments, etc. Indeed, the relative displacement of the sleeve 8 relative to the rod 7 makes it possible to vary the volume of the sampling and application space E and to create a piston effect which makes it possible to draw the fluid product to the Inside the space E. While the volume of the space E is zero in Figure 1, it increases gradually as can be seen through Figures 4a to 4d to finally reach a maximum volume. We can still say that the sampling and application space E defines an open end of application formed by the lower end 86 of the sleeve 8 and a closed end formed by the lower end 76 of the rod 7. These two ends move the relative to each other so as to vary the volume of the space E.
En d'autres termes, l'espace de prélèvement et d'application E présente un volume variable entre un volume minimal lorsque la chambre d'aspiration C présente un volume minimal et un volume maximal lorsque la chambre d'aspiration C présente un volume maximal.  In other words, the sampling and application space E has a variable volume between a minimum volume when the suction chamber C has a minimum volume and a maximum volume when the suction chamber C has a maximum volume .
Une fois l'organe de prélèvement et d'application P retiré de la bague 2, avec son espace de prélèvement et d'application E rempli, on peut appliquer l'extrémité ouverte d'application 86 du manchon 8 sur une surface d'application souhaitée, comme par exemple la peau de l'utilisateur. Ceci est représenté sur la figure 5. A mesure que l'on appuie sur la peau, le manchon 8 se déplace par rapport à la tige 7 ce qui a pour effet de réduire le volume de l'espace E. Le produit fluide (crème, gel) qu'il contient est ainsi refoulé à l'extérieur sur la peau de l'utilisateur. L'application du produit fluide se termine lorsque l'extrémité 76 de la tige est à nouveau alignée avec l'extrémité ouverte d'application 86 du manchon 8 comme représenté sur la figure 6. L'organe de prélèvement et d'application P peut alors à nouveau être remis en place dans la bague 2 pour parvenir à la configuration représentée sur la figure 1 . Un cycle opératoire complet est alors achevé.  Once the sampling and application member P removed from the ring 2, with its sampling and application space E filled, it is possible to apply the open application end 86 of the sleeve 8 to an application surface. desired, such as the skin of the user. This is shown in FIG. 5. As the skin is pressed, the sleeve 8 moves relative to the rod 7 which has the effect of reducing the volume of the space E. The fluid product (cream , gel) that it contains is thus pushed back on the skin of the user. The application of the fluid product ends when the end 76 of the rod is again aligned with the open end of application 86 of the sleeve 8 as shown in Figure 6. The sampling and application member P can then again be put back in the ring 2 to achieve the configuration shown in Figure 1. A complete operating cycle is then completed.
On peut remarquer que l'augmentation de volume de l'espace E se produit avant que le manchon 8 ne coulisse à l'intérieur de la lèvre d'étanchéité 31 . Cet ordre de séquence est défini par les valeurs de frottement qui existent d'une part entre le manchon 8 et la lèvre 31 et d'autre part entre le manchon 8 et la tige 7. En inversant ces valeurs de frottement, il serait possible d'inverser l'ordre de séquence, de sorte que le manchon 8 commencerait à se déplacer dans la lèvre 31 avant l'augmentation de volume de l'espace E. Toutefois, dans ce cas, il serait nécessaire de prévoir des moyens pour stopper le coulissement du manchon 8 dans la lèvre 31 avant leur séparation pour permettre l'augmentation de volume de l'espace E et son remplissage par aspiration avec du produit fluide en provenance du réservoir. On pourrait par exemple envisager de réaliser le manchon 8 avec une forme extérieure légèrement tronconique de sorte que les forces de frottement avec la lèvre 31 augmentent au fur et à mesure de son retrait. It may be noted that the increase in volume of the space E occurs before the sleeve 8 slides inside the sealing lip 31. This sequence order is defined by the friction values that exist on the one hand between the sleeve 8 and the lip 31 and on the other hand between the sleeve 8 and the rod 7. By reversing these friction values, it would be possible to reverse the sequence order, so that the sleeve 8 would begin to move in the lip 31 before the volume increase of the space E. However, in this case, it would be necessary to provide means to stop the sliding of the sleeve 8 in the lip 31 before separation to allow the volume increase of the space E and filling by suction with fluid from the reservoir. One could for example consider making the sleeve 8 with a slightly frustoconical outer shape so that the frictional forces with the lip 31 increase as it withdraws.
On peut également remarquer que le déplacement du manchon 8 par rapport à la tige 7 et à la lèvre 31 s'effectue sans aucune sollicitation élastique, par exemple généré par un ressort de rappel. Il s'ensuit que le distributeur de l'invention peut être réalisé sans métal et procurer un contact doux sur la peau.  It can also be noted that the displacement of the sleeve 8 relative to the rod 7 and to the lip 31 takes place without any elastic bias, for example generated by a return spring. It follows that the dispenser of the invention can be made without metal and provide a soft contact on the skin.
Grâce à l'invention, on obtient un distributeur comprenant une chambre d'aspiration C définissant un espace de prélèvement et d'application E de volume variable de manière à améliorer son remplissage et à favoriser son vidage. On garantit ainsi un remplissage complet et un vidage complet de l'espace de prélèvement et d'application E.  Thanks to the invention, there is obtained a distributor comprising a suction chamber C defining a sampling and application space E of variable volume so as to improve its filling and to promote emptying. This guarantees a complete filling and a complete emptying of the sampling and application space E.
