Description

La présente invention concerne un distributeur de produit fluide comprenant un réservoir de produit fluide, un organe de distribution, tel qu'une pompe ou une valve, ayant une tige de soupape déplaçable axialement et/ou en rotation, un poussoir monté sur la tige de soupape et une bague de fixation pour fixer l'organe de distribution sur le réservoir de produit fluide. Il s'agit là d'une conception tout à fait classique pour un distributeur de produit fluide dans les domaines de la parfumerie, la cosmétique, la pharmacie, etc.The present invention relates to a fluid dispenser comprising a fluid reservoir, a dispensing member, such as a pump or a valve, having a valve stem movable axially and / or in rotation, a pusher mounted on the stem. valve and a fixing ring for fixing the dispensing member to the fluid reservoir. This is a completely classic design for a fluid dispenser in the fields of perfumery, cosmetics, pharmacy, etc.

Dans un distributeur classique, le poussoir comprend un manchon de raccordement qui est engagé en force autour de l'extrémité libre de la tige de soupape. Cet emmanchage à force est réalisé en usine par une machine qui appuie axialement le poussoir sur la tige de soupape avec une force de l'ordre de 12 Kg. L'utilisateur final ne se soucie pas du mode de raccordement du poussoir sur la tige de soupape, car il n'a normalement pas l'occasion de retirer le poussoir de la tige de soupape.In a conventional dispenser, the plunger comprises a connection sleeve which is forcibly engaged around the free end of the valve stem. This force-fitting is carried out in the factory by a machine which presses the tappet axially on the valve stem with a force of the order of 12 Kg. The end user does not worry about the connection method of the tappet on the valve stem valve, as it does not normally have the opportunity to remove the valve stem from the valve stem.

Dans un distributeur classique, la tige de soupape est libre de tourner sur elle-même, de sorte que le poussoir, une fois monté sur la tige de soupape, peut tourner sur lui-même autour de l'axe de la tige de soupape. Cela permet à l'utilisateur d'orienter le poussoir comme il le souhaite. Des distributeurs de produit fluide de l'état de l'art sont divulgués dans WO 2007/024387 A2 , WO 97/32808 A1 , US 4 318 498 A , US 5 405 057 A et JP 2015 155329 A .In a conventional dispenser, the valve stem is free to rotate on itself, so that the plunger, once mounted on the valve stem, can rotate on itself around the axis of the valve stem. This allows the user to orient the pusher as he wishes. State of the art fluid dispensers are disclosed in WO 2007/024387 A2 , WO 97/32808 A1 , US 4,318,498 A , US 5,405,057 A and JP 2015 155329 A .

Toutefois, il existe certaines situations où il est nécessaire de retirer le poussoir de la tige de soupape. C'est notamment le cas avec les distributeurs rechargeables ou « nomade » qui comprennent un clapet de remplissage adapté à recevoir la tige de soupape d'un flacon ou distributeur source. De ce fait, il est nécessaire de retirer le poussoir de ce distributeur ou flacon source de manière à rendre sa tige de soupape accessible. L'utilisateur peut retirer le poussoir de la tige de soupape en exerçant une traction qui est de l'ordre de 1 à 2 Kg. Le problème majeur ne se pose pas lors du retrait du poussoir, mais lors de sa remise en place sur la tige de soupape. En effet, cela nécessite d'appuyer fortement le poussoir sur la tige de soupape, qui est de ce fait enfoncée dans le corps de l'organe de distribution, ce qui a pour résultat de refouler du produit fluide à travers la tige de soupape et le poussoir. Il est donc pratiquement impossible de remettre le poussoir en place sur la tige de soupape sans distribuer du produit fluide, ce qui est bien entendu gênant, puisque non souhaité.However, there are certain situations where it is necessary to remove the tappet from the valve stem. This is particularly the case with refillable or “nomadic” distributors which include a filling valve adapted to receive the valve stem from a source bottle or distributor. Therefore, it is necessary to remove the pusher from this distributor or source bottle so as to make its valve stem accessible. The user can remove the tappet from the valve stem by exerting a traction which is of the order of 1 to 2 kg. The major problem does not arise when the tappet is removed, but when it is replaced on the valve stem. Indeed, this requires strongly pressing the pusher on the valve stem, which is thereby pressed into the body of the valve member. distribution, which results in the delivery of fluid through the valve stem and the tappet. It is therefore practically impossible to put the pusher back in place on the valve stem without dispensing fluid, which is of course troublesome, since it is not desired.

Le but de la présente invention est de remédier à l'inconvénient précité de l'art antérieur en définissant un distributeur de produit fluide dont le poussoir peut être remis en place sur la tige de soupape sans risque de distribution de produit fluide. Un autre but de la présente invention est de mettre en œuvre des moyens spécifiques pour empêcher cette distribution non souhaitée de produit fluide, tout en veillant à ne pas modifier, ou du moins au minimum, la conception d'un distributeur de produit fluide classique.The object of the present invention is to remedy the aforementioned drawback of the prior art by defining a fluid dispenser whose plunger can be replaced on the valve stem without risk of dispensing fluid. Another object of the present invention is to implement specific means to prevent this unwanted distribution of fluid, while being careful not to modify, or at least at least, the design of a conventional fluid dispenser.

Pour atteindre ces buts, la présente invention propose que la tige de soupape soit pourvue d'un organe de blocage comprenant un élément d'appui destiné à coopérer avec au moins une butée solidaire de la bague de fixation pour bloquer la tige de soupape axialement et/ou en rotation afin de permettre le montage du poussoir sans déplacer la tige de soupape, l'organe de blocage comprenant une douille engagée fixement autour de la tige de soupape. Le poussoir est monté soit sur cette douille, soit directement sur la tige de soupape. Il faut noter que la tige de soupape peut être tout à fait classique. La douille permet la fixation de l'organe de blocage sur la tige de soupape, sans qu'il soit nécessaire de la modifier ou de lui rajouter une pièce supplémentaire. Par conséquent, l'organe de blocage peut être fixé sur la tige de soupape d'une pompe ou d'une valve standard.To achieve these aims, the present invention proposes that the valve stem be provided with a blocking member comprising a support element intended to cooperate with at least one stop integral with the fixing ring for blocking the valve stem axially and / or in rotation in order to allow mounting of the valve without moving the valve stem, the blocking member comprising a socket fixedly engaged around the valve stem. The tappet is mounted either on this sleeve or directly on the valve stem. Note that the valve stem can be quite conventional. The sleeve allows the fixing of the blocking member on the valve stem, without it being necessary to modify it or to add an additional part to it. Therefore, the blocking member can be attached to the valve stem of a standard pump or valve.

Avantageusement, l'organe de blocage comprend une bride radiale qui relie la douille à l'élément d'appui. Ainsi, on peut dire que l'élément d'appui est situé plus en éloignement de la tige de soupape que la douille.Advantageously, the blocking member comprises a radial flange which connects the bush to the support element. Thus, it can be said that the support element is located further away from the valve stem than the sleeve.

L'organe de blocage est monté sur la tige de soupape de manière à interdire tout mouvement ou déplacement relatif. L'organe de blocage peut simplement être engagé en force autour de la tige de soupape : on peut également imaginer que des profils d'accrochage appropriés complètent ou améliorent la tenue de l'organe de blocage sur la tige de soupape. Dans tous les cas, il ne faut pas que le montage du poussoir sur la tige de soupape ou sur l'organe de blocage engendre un déplacement de la tige de soupape provoquant une distribution de produit fluide. La butée avec laquelle coopère l'organe de blocage peut être formée par la bague de fixation ou par une pièce rapportée sur la bague de fixation.The blocking member is mounted on the valve stem so as to prevent any relative movement or displacement. The blocking member can simply be forcibly engaged around the valve stem: it can also be imagined that suitable attachment profiles supplement or improve the behavior of the blocking member on the valve stem. In all in these cases, the mounting of the valve plunger on the valve stem or on the blocking member must not cause the valve stem to move, causing a distribution of fluid. The stop with which the locking member cooperates can be formed by the fixing ring or by an insert on the fixing ring.

Selon une caractéristique avantageuse de l'invention, l'élément d'appui coopère avec la butée uniquement dans une position angulaire déterminée du poussoir par rapport à la bague de fixation. Par conséquent, il est nécessaire d'amener le poussoir par rotation dans une position angulaire déterminée avant de remettre le poussoir en place sur la tige de soupape. Dans cette position angulaire déterminée, l'organe de blocage empêche tout déplacement axial et/ou rotatif de la tige de soupape.According to an advantageous characteristic of the invention, the support element cooperates with the stop only in a determined angular position of the pusher relative to the fixing ring. Consequently, it is necessary to bring the tappet by rotation to a determined angular position before replacing the tappet on the valve stem. In this determined angular position, the locking member prevents any axial and / or rotary movement of the valve stem.

Selon un mode de réalisation, la butée comprend une butée en rotation contre laquelle l'élément d'appui vient en contact par rotation, l'organe de blocage comprenant une douille filetée engagée fixement autour de la tige de soupape et sur laquelle un manchon fileté du poussoir est vissé. Ainsi, le dévissage du poussoir va commencer dès lors que l'élément d'appui est en contact de la butée en rotation. Avantageusement, la butée comprend une butée axiale contre laquelle l'élément d'appui vient en contact par déplacement axial, lorsqu'il est en contact de la butée en rotation. Ainsi, la butée en rotation peut être complétée par une butée axiale qui empêche tout enfoncement de la tige d'actionnement, dès lors que l'élément d'appui est en contact de la butée en rotation. Cette butée axiale constitue ainsi une sécurité supplémentaire qui n'est pas absolument nécessaire.According to one embodiment, the stop comprises a rotational stop against which the support element comes into contact by rotation, the locking member comprising a threaded sleeve fixedly engaged around the valve stem and on which a threaded sleeve of the pusher is screwed. Thus, the unscrewing of the pusher will start as soon as the support element is in contact with the rotating stop. Advantageously, the stop comprises an axial stop against which the support element comes into contact by axial displacement, when it is in contact with the rotational stop. Thus, the rotational stop can be supplemented by an axial stop which prevents any depression of the actuating rod, as soon as the support element is in contact with the rotational stop. This axial stop thus constitutes additional security which is not absolutely necessary.

Selon une autre forme de réalisation de l'invention, la butée peut comprendre une butée axiale contre laquelle l'élément d'appui vient en contact par déplacement axial, l'organe de blocage comprenant une douille lisse engagée fixement autour de la tige de soupape et sur laquelle un manchon lisse du poussoir est engagé axialement. L'utilisateur devra donc veiller à ce que l'élément d'appui soit en contact de la butée axiale avant d'emmancher le poussoir en force sur la douille lisse. Par « douille lisse », on entend une douille à emmanchement axial, par opposition à une douille filetée.According to another embodiment of the invention, the stop may include an axial stop against which the support element comes into contact by axial displacement, the blocking member comprising a smooth sleeve fixedly engaged around the valve stem and on which a smooth sleeve of the pusher is engaged axially. The user must therefore ensure that the support element is in contact with the axial stop before pushing the pusher in force on the smooth sleeve. By "smooth socket", we means an axially fitted socket, as opposed to a threaded socket.

Selon encore un autre mode de réalisation de l'invention, la butée peut comprendre une butée axiale contre laquelle l'élément d'appui vient en contact par déplacement axial, le poussoir comprenant un manchon de raccordement classique engagé axialement autour de la tige de soupape. Dans ce cas, le poussoir peut être un poussoir classique ou conventionnel, puisque son raccordement se fait directement sur la tige de soupape, qui peut elle aussi, être classique ou conventionnelle. L'organe de blocage n'intervient pas dans le raccordement du poussoir sur la tige de soupape. De plus, en formant la butée sur une pièce rapportée, le distributeur peut être tout à fait conventionnel, hormis qu'il soit pourvu d'un organe de blocage et d'une pièce réalisant la butée.According to yet another embodiment of the invention, the stop may include an axial stop against which the support element comes into contact by axial displacement, the pusher comprising a conventional connection sleeve engaged axially around the valve stem . In this case, the pusher can be a conventional or conventional pusher, since its connection is made directly to the valve stem, which can also be conventional or conventional. The blocking member does not intervene in the connection of the valve lifter to the valve stem. In addition, by forming the stop on an insert, the dispenser can be entirely conventional, except that it is provided with a blocking member and with a part making the stop.

Lorsque la bague de fixation forme la butée, elle peut comprendre un logement de réception pour l'organe de distribution, la butée étant formée par un relief externe de ce logement de réception.When the fixing ring forms the stop, it can comprise a reception housing for the dispensing member, the stop being formed by an external relief of this reception housing.

Dans certains cas, il est préférable que la bague de fixation comprenne deux butées disposées de manière opposée de part et d'autre de la tige de soupape.In some cases, it is preferable that the fixing ring comprises two stops arranged in opposite directions on either side of the valve stem.

L'esprit de l'invention réside dans le fait de bloquer la tige de soupape axialement et/ou en rotation pour permettre la remise en place du poussoir sur la tige de soupape, sans modifier grandement, voire pas du tout, les pièces constitutives d'un distributeur de produit fluide classique ou conventionnel. L'organe de blocage de l'invention est une pièce simplement rapportée fixement sur la tige de soupape, et la butée peut être formée par une pièce rapportée sur la bague de fixation ou être directement formée par la bague de fixation. Le poussoir peut être monté par vissage sur l'organe de blocage, ou encore par emmanchement en force axiale sur l'organe de blocage ou directement sur la tige de soupape. La butée peut être une butée en rotation ou une butée axiale, ou encore une butée en rotation complétée par une butée axiale.The spirit of the invention resides in the fact of blocking the valve stem axially and / or in rotation to allow the repositioning of the pusher on the valve stem, without greatly modifying, if not at all, the constituent parts of the valve. '' a classic or conventional fluid dispenser. The locking member of the invention is a piece simply attached fixedly to the valve stem, and the stop can be formed by an attached piece on the fixing ring or be directly formed by the fixing ring. The plunger can be mounted by screwing on the blocking member, or even by axial force fitting on the blocking member or directly on the valve stem. The stop can be a rotary stop or an axial stop, or even a rotary stop supplemented by an axial stop.

L'invention sera maintenant décrite plus en détail en référence aux dessins joints, donnant à titre d'exemples non limitatifs, trois 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 nonlimiting examples, three embodiments of the invention.

  • The figure 4 is a view similar to the figure 2a for this second embodiment of the invention, and
  • The Figures 5a and 5b are views respectively similar to Figures 1a and 1b for a third embodiment of the invention.

On se référera tout d'abord à la figure 1a pour décrire la structure générale d'un distributeur de produit fluide. Ce distributeur comprend un réservoir de produit fluide R, un organe de distribution D, qui peut être une pompe ou une valve, une bague de fixation F pour fixer l'organe de distribution D sur une ouverture du réservoir R et un poussoir P monté sur une tige de soupape T faisant partie de l'organe de distribution D.We will first refer to the figure 1a to describe the general structure of a fluid dispenser. This dispenser comprises a reservoir of fluid R, a dispensing member D, which may be a pump or a valve, a fixing ring F for fixing the dispensing member D on an opening of the reservoir R and a pusher P mounted on a valve stem T forming part of the dispensing member D.

Le réservoir de produit fluide R peut être de toute nature, de tout matériau et de toute forme. Il peut être réalisé en verre, en matière plastique, en métal, etc. Il comprend une ouverture, qui peut être formée par un col de diamètre réduit. Ce col peut également former un profil d'accrochage pour la bague de fixation.The fluid reservoir R can be of any kind, of any material and of any shape. It can be made of glass, plastic, metal, etc. It includes an opening, which can be formed by a neck of reduced diameter. This neck can also form an attachment profile for the fixing ring.

L'organe de distribution D peut être une pompe ou une valve. Il comprend un corps D1 pourvu à son extrémité inférieure d'un tube plongeur D2 et à son extrémité supérieure d'une collerette saillante D3. L'organe de distribution D comprend également une tige de soupape T qui est déplaçable axialement en va et vient à l'intérieur du corps D1. L'enfoncement de la tige de soupape T dans le corps D1 a pour effet de distribuer du produit fluide à travers la tige de soupape. Il s'agit là d'une conception tout à fait classique pour une pompe ou une valve dans les domaines de la parfumerie, de la cosmétique ou encore de la pharmacie.The dispensing member D can be a pump or a valve. It comprises a body D1 provided at its lower end with a dip tube D2 and at its upper end with a projecting flange D3. The dispensing member D also includes a valve stem T which is movable axially back and forth inside the body D1. The depression of the valve stem T in the body D1 has the effect of distributing fluid product through the valve stem. This is a completely classic design for a pump or a valve in the fields of perfumery, cosmetics or even pharmacy.

La bague de fixation F comprend une jupe de fixation F1 destinée à venir en prise stable et étanche avec l'ouverture du réservoir R. La jupe F1 peut par exemple former des profils d'accrochage destinés à venir en prise avec des profils correspondants formés par la paroi externe du col du réservoir. La jupe de la bague de fixation pourrait également être une jupe vissable ou encore une jupe destinée à venir en prise à l'intérieur de l'ouverture du réservoir. La bague de fixation F comprend également un plateau annulaire F2 qui s'étend radialement vers l'intérieur à partir de la jupe F1. Ce plateau F2 peut servir à comprimer un joint de col contre le bord annulaire supérieur de l'ouverture du réservoir R. La bague de fixation F comprend également un logement de réception F3 dans lequel est reçue la collerette saillante D3. Le logement de réception F3 définit une ouverture centrale axiale à travers laquelle passe la tige de soupape T. Il s'agit là d'une conception tout à fait classique pour une bague de fixation dans les domaines de la parfumerie, de la cosmétique ou encore de la pharmacie. La jupe de fixation F1 forme également au niveau de sa partie supérieure une fenêtre F5.The fixing ring F comprises a fixing skirt F1 intended to come into stable and tight engagement with the opening of the reservoir R. The skirt F1 can for example form hooking profiles intended to come into engagement with corresponding profiles formed by the outer wall of the tank neck. The skirt of the fixing ring could also be a screwable skirt or a skirt intended to come into engagement inside the opening of the reservoir. The fixing ring F also comprises an annular plate F2 which extends radially inwards from the skirt F1. This plate F2 can be used to compress a neck seal against the upper annular edge of the opening of the reservoir R. The fixing ring F also comprises a receiving housing F3 in which the projecting collar D3 is received. The receiving housing F3 defines an axial central opening through which the valve stem T passes. This is a completely conventional design for a fixing ring in the fields of perfumery, cosmetics or else from the pharmacy. The fastening skirt F1 also forms at its upper part a window F5.

Le poussoir P définit un orifice de distribution P0 qui est relié à la sortie de la tige de soupape T. Le poussoir P comprend un manchon de raccordement P1 pour réaliser la connexion fluidique entre la tige de soupape T et l'orifice de distribution P0. Ainsi, un utilisateur peut appuyer axialement sur le poussoir P pour enfoncer la tige de soupape T dans le corps D1 de l'organe de distribution D, de manière à distribuer du produit fluide, sous forme dosée ou non. La distribution peut se faire sous forme pulvérisée, ou encore sous forme de cordon ou de noisette. A nouveau, il s'agit d'une conception tout à fait classique pour un poussoir dans les domaines de la cosmétique, de la pharmacie ou encore de la parfumerie.The pusher P defines a dispensing orifice P0 which is connected to the outlet of the valve stem T. The pusher P comprises a connection sleeve P1 for making the fluid connection between the valve stem T and the dispensing orifice P0. Thus, a user can press the pusher P axially to push the valve stem T into the body D1 of the dispensing member D, so as to dispense fluid product, in metered form or not. Distribution can be in spray form, or in the form of a bead or hazelnut. Again, this is a completely classic design for a pusher in the fields of cosmetics, pharmacy or even perfumery.

Selon l'invention, la bague de fixation F, avantageusement au niveau de son logement de réception F3, forme une butée 2 qui est plus visible en détail sur les figures 2a et 2b. En effet, on peut y voir que cette butée 2 comprend une butée en rotation 21 et une butée axiale 22, qui sont disposées de manière contigüe ou adjacente. La butée 2 est ici formée par un profil ou un relief extérieur du logement de réception F3. On peut aussi remarquer sur ces figures que la butée 2 est formée au niveau de la fenêtre F5 de la jupe F4.According to the invention, the fixing ring F, advantageously at its receiving housing F3, forms a stop 2 which is more visible in detail on the Figures 2a and 2b . Indeed, it can be seen that this stop 2 comprises a rotational stop 21 and an axial stop 22, which are arranged contiguously or adjacent. The stop 2 is here formed by a profile or an external relief of the receiving housing F3. It can also be noted in these figures that the stop 2 is formed at the level of the window F5 of the skirt F4.

Selon l'invention, la tige de soupape T est pourvue d'un organe de blocage 1 qui forme un élément d'appui 11 destiné à venir en contact avec la butée 2, comme on peut le voir sur les figure 1a et 2a. Plus précisément, l'organe de blocage 1 comprend une douille filetée 12 qui est montée ou engagée fixement autour de la tige de soupape T. Le filetage de la douille filetée 12 est situé sur sa paroi extérieure. A partir de l'extrémité inférieure, de cette douille filetée 12 s'étend une bride radiale 13 à l'extrémité périphérique de laquelle s'étend l'élément d'appui 11 vers le bas. La bride radiale 13 peut se présenter sous la forme d'une ou de plusieurs patte(s) ou encore sous la forme d'un disque. L'élément d'appui 11 peut se présenter sous la forme d'une patte ou d'une barrette qui pointe vers le bas à partir de la bride radiale 13. Lorsque la tige de soupape T est au repos, c'est-à-dire non enfoncée, l'élément d'appui 11 peut être amené par rotation en contact de la butée 2, c'est-à-dire à la fois en contact de la butée en rotation 21 et de la butée axiale 22. L'utilisateur peut parvenir à cette position en faisant tourner le poussoir sur lui-même autour de l'axe passant par la tige de soupape T. Le poussoir P est alors bloqué à la fois en rotation dans le sens des aiguilles d'une montre et en déplacement axial.According to the invention, the valve stem T is provided with a locking member 1 which forms a support element 11 intended to come into contact with the stop 2, as can be seen in the figure 1a and 2a . More specifically, the locking member 1 comprises a threaded sleeve 12 which is fixedly mounted or engaged around the valve stem T. The thread of the threaded sleeve 12 is located on its outer wall. From the lower end, from this threaded sleeve 12 extends a radial flange 13 at the peripheral end of which the support element 11 extends downwards. The radial flange 13 can be in the form of one or more tab (s) or also in the form of a disc. The support element 11 may be in the form of a tab or a bar which points downwards from the radial flange 13. When the valve stem T is at rest, that is to say ie not pressed, the support element 11 can be brought by rotation into contact with the stop 2, that is to say both in contact with the rotary stop 21 and the axial stop 22. L user can reach this position by rotating the pusher on itself around the axis passing through the valve stem T. The pusher P is then locked both in rotation clockwise and in axial displacement.

Selon l'invention, le manchon de raccordement P1 du poussoir P est fileté intérieurement de manière à pouvoir être vissé sur la douille filetée 12 de l'organe de blocage 1. Le vissage du poussoir P sur la douille 12 peut par exemple être effectué dans le sens des aiguilles d'une montre. Ainsi, lorsqu'un utilisateur visse le poussoir P sur la douille 12 il va automatiquement faire tourner la tige de soupape T et l'organe de blocage 1 pour parvenir à la position représentée sur la figure 2a, avec l'élément d'appui 11 en contact à la fois de la butée en rotation 21 et de la butée axiale 22. Dès que cette position est atteinte, l'utilisateur pourra visser à fond le poussoir sur la tige de soupape T sans risque de l'entraîner en rotation et sans risque de l'enfoncer axialement.According to the invention, the connection sleeve P1 of the pusher P is internally threaded so that it can be screwed onto the threaded sleeve 12 of the locking member 1. The screwing of the pusher P onto the sleeve 12 can for example be carried out in clockwise. Thus, when a user screws the pusher P on the sleeve 12 he will automatically rotate the valve stem T and the locking member 1 to reach the position shown on the figure 2a , with the support element 11 in contact with both the rotational stop 21 and the axial stop 22. As soon as this position is reached, the user can screw the plunger fully onto the valve stem T without risk of driving it in rotation and without risk of driving it axially.

Lorsque l'utilisateur veut retirer le poussoir P de la tige de soupape T, il va faire tourner le poussoir dans le sens inverse des aiguilles d'une montre jusqu'à ce que l'élément d'appui 11 vienne en contact avec l'autre face de la butée en rotation 21, comme représenté sur la figure 2b. A partir de cette position, la tige de soupape T est bloquée en rotation et le manchon fileté P1 va alors se dévisser de la douille filetée 12 jusqu'à ce que le poussoir P se détache complètement de la douille.When the user wants to remove the pusher P from the valve stem T, he will rotate the pusher anti-clockwise until the support element 11 comes into contact with the other face of the rotational stop 21, as shown in the figure 2b . From this position, the valve stem T is locked in rotation and the threaded sleeve P1 will then unscrew from the threaded sleeve 12 until the pusher P detaches completely from the sleeve.

Dans ce premier mode de réalisation, la butée 2 comprend à la fois une butée en rotation 21 et une butée axiale 22. Toutefois, la butée axiale est optionnelle, de sorte que la butée 2 peut également se résumer à une seule butée en rotation 21. En effet, dans le cas d'un poussoir à visser, il n'est pas indispensable de bloquer la tige de soupape D dans le sens axial. Cependant, il ne peut être exclu que l'utilisateur exerce une certaine poussée axiale sur le poussoir P en fin de vissage. C'est pourquoi la mise en œuvre d'une butée axiale 22 est avantageuse.In this first embodiment, the stop 2 comprises both a rotary stop 21 and an axial stop 22. However, the axial stop is optional, so that the stop 2 can also be summarized as a single rotary stop 21 In fact, in the case of a screw-in plunger, it is not essential to block the valve stem D in the axial direction. However, it cannot be excluded that the user exerts a certain axial thrust on the pusher P at the end of screwing. This is why the implementation of an axial stop 22 is advantageous.

On se référera maintenant aux figures 3a, 3b et 4 pour décrire le second mode de réalisation de l'invention. Seules les différences avec le premier mode de réalisation seront décrites. La bague de fixation F comprend ici deux butées 2' qui sont disposées de manière diamétralement opposée par rapport à la tige de soupape T. En se référant à la figure 4, on peut voir une butée 2' qui définit uniquement une butée axiale 22 sur laquelle un élément d'appui 11 peut venir en butée axiale. Il n'y a pas de butée en rotation.We will now refer to Figures 3a, 3b and 4 to describe the second embodiment of the invention. Only the differences with the first embodiment will be described. The fixing ring F here comprises two stops 2 'which are arranged diametrically opposite with respect to the valve stem T. With reference to the figure 4 , we can see a stop 2 'which defines only an axial stop 22 on which a support element 11 can come into axial stop. There is no rotational stop.

L'élément de blocage 1' comprend une douille lisse 12', une bride radiale 13 et deux éléments d'appui 11, qui sont également disposés de manière diamétralement opposée par rapport à la tige de soupape T. Ainsi, il est possible d'amener les deux éléments d'appui 11 simultanément en appui sur les deux butées 2' par rotation du poussoir P autour de l'axe de la tige de soupape T. La disposition diamétralement opposée des butées 2' et des éléments d'appui 11 garantit une parfaite stabilité axiale de la tige de soupape T, même si l'on exerce une poussée importante sur elle.The blocking element 1 'comprises a smooth bush 12', a radial flange 13 and two support elements 11, which are also arranged diametrically opposite with respect to the valve stem T. Thus, it is possible to bring the two support elements 11 simultaneously in support on the two stops 2 ′ by rotation of the pusher P around the axis of the valve stem T. The diametrically opposite arrangement of the stops 2 ′ and the support elements 11 guarantees perfect axial stability of the valve stem T, even if you exert a significant push on it.

Le poussoir P comprend un manchon de raccordement lisse P2 qui est destiné à venir en ajustement serré avec la douille lisse 12'. Le terme « lisse » doit être compris par opposition au terme « fileté », en ce sens que le manchon de raccordement lisse P2 est engagé axialement sans composante rotative autour de la douille lisse 12'. Le terme « lisse » n'exclut pas que la douille 12' et/ou le manchon de raccordement P2 comporte(nt) des profils d'accrochage, de harponnage ou d'encliquetage.The pusher P comprises a smooth connection sleeve P2 which is intended to come into tight fit with the smooth sleeve 12 '. The term "smooth" should be understood as opposed to the term "threaded", in the sense that the smooth connection sleeve P2 is engaged axially without rotating component around the smooth bush 12 '. The term “smooth” does not exclude that the bush 12 ′ and / or the connection sleeve P2 comprises (s) attachment, harpooning or latching profiles.

Grâce aux deux butées 2' et aux deux éléments d'appui 11, le poussoir P peut être engagé en force sur l'élément de blocage 1' sans risque d'enfoncer la tige de soupape T.Thanks to the two stops 2 'and the two support elements 11, the pusher P can be forcibly engaged on the blocking element 1' without risk of pushing the valve stem T.

Bien que non représenté, il est possible que les butées 2' soient également pourvues de butées en rotation pour s'assurer que les éléments d'appui 11 sont bien en position sur les butées axiales 22.Although not shown, it is possible that the stops 2 ′ are also provided with rotational stops to ensure that the support elements 11 are indeed in position on the axial stops 22.

On se référera maintenant aux figures 5a et 5b pour décrire un troisième mode de réalisation de l'invention. Seules les différences avec le second mode de réalisation seront décrites. L'organe de blocage 1" comprend une douille tronquée 12" qui laisse l'extrémité supérieure de la tige de soupape T parfaitement dégagée de sorte qu'un poussoir conventionnel P avec un manchon de raccordement conventionnel P3 peut être engagé en force autour de la tige de soupape T. Le manchon de raccordement classique P3 peut même venir en butée axiale sur la douille tronquée 12". Ainsi, dans ce troisième mode de réalisation, l'organe de distribution D et le poussoir P peuvent être d'un type tout à fait classique ou conventionnel. De plus, il est possible de réaliser les butées 2' au moyen d'une pièce rapportée autour du logement de réception F3 de la bague de fixation F, de sorte que la bague de fixation F peut également être d'un type classique ou conventionnel. Dans ce cas, la présente invention peut être très simplement mis en œuvre par l'ajout de deux pièces rapportées, à savoir l'organe de blocage 1" et une pièce de butée rapportée autour de la bague de fixation F.We will now refer to Figures 5a and 5b to describe a third embodiment of the invention. Only the differences with the second embodiment will be described. The blocking member 1 "comprises a truncated sleeve 12" which leaves the upper end of the valve stem T perfectly clear so that a conventional plunger P with a conventional connection sleeve P3 can be forcibly engaged around the valve stem T. The conventional connection sleeve P3 can even come into axial abutment on the truncated sleeve 12 ". Thus, in this third embodiment, the distribution member D and the pusher P can be of an all type classic or conventional. In addition, it is possible to make the stops 2 ′ by means of an insert around the receiving housing F3 of the fixing ring F, so that the fixing ring F can also be a conventional or conventional type. In this case, the present invention can be very simply implemented by the addition of two inserts, namely the 1 "blocking member and an abutment insert around the fixing ring F.

Les différents modes de réalisation décrits mettent en œuvre une ou deux butée(s) associée(s) à un ou deux élément(s) d'appui 11. Sans sortir du cadre de l'invention, on peut imaginer des modes de réalisation avec plus de deux butées et plus de deux éléments d'appui. La douille de l'organe de blocage est montée en force autour de la tige de soupape T. On peut également imaginer que la douille soit vissée, ou encore soudée. Les butées sont prévues sur l'extérieur du logement de réception F3 : on peut toutefois imaginer des modes de réalisation dans lesquels les butées sont réalisées sur la partie supérieure du logement de réception F3. On peut également imaginer de réaliser les butées au niveau du plateau de la bague de fixation F.The various embodiments described implement one or two abutment (s) associated with one or two support element (s) 11. Without departing from the scope of the invention, it is possible to imagine embodiments with more than two stops and more than two supporting elements. The sleeve of the blocking member is mounted in force around the valve stem T. It is also conceivable that the sleeve is screwed, or even welded. The stops are provided on the outside of the reception housing F3: one can however imagine embodiments in which the stops are produced on the upper part of the reception housing F3. One can also imagine making the stops at the level of the fixing ring F.

Grâce à l'invention, on dispose d'un distributeur de produit fluide dont la remise en place du poussoir sur la tige de soupape peut être effectuée sans risque d'actionner l'organe de distribution. Un tel distributeur peut notamment servir de flacon source pour recharger un distributeur rechargeable ou « nomade ».Thanks to the invention, there is a fluid dispenser whose replacement of the pusher on the valve stem can be performed without risk of actuating the dispensing member. Such a dispenser can in particular serve as a source bottle for recharging a refillable or “nomadic” dispenser.
