Description

Domaine de l'inventionField of the invention

L'invention concerne un ensemble de distribution d'un produit fluide, avec un réservoir contenant le produit fluide, et un dispositif de fixation d'une pompe de distribution sur le col du réservoir. Cette invention concerne également un procédé de montage et de démontage facilité de la pompe par rapport au réservoir.The invention relates to an assembly for dispensing a fluid product, with a reservoir containing the fluid product, and a device for fixing a dispensing pump to the neck of the reservoir. This invention also relates to a method for easy assembly and disassembly of the pump relative to the reservoir.

En particulier, l'ensemble de distribution permet le conditionnement et la distribution d'un liquide ou d'une crème, par exemple un parfum, pour une application cosmétique ou pharmaceutique.In particular, the distribution assembly allows the packaging and distribution of a liquid or a cream, for example a perfume, for a cosmetic or pharmaceutical application.

Etat de la techniqueState of the art

On connaît de tels ensembles de distribution comprenant un réservoir de conditionnement du produit, formé par un corps surmonté d'un col définissant une ouverture supérieure pour ledit réservoir, et une pompe montée dans ladite ouverture supérieure en disposant les moyens d'alimentation de ladite pompe à l'intérieur dudit réservoir. Ainsi, la pompe permet de restituer le produit conditionné dans le réservoir.Such dispensing assemblies are known comprising a product conditioning reservoir, formed by a body surmounted by a neck defining an upper opening for said reservoir, and a pump mounted in said upper opening by arranging the supply means of said pump. inside said reservoir. Thus, the pump allows the product packaged to be returned to the tank.

Pour assurer le positionnement et la fixation de la pompe par rapport au corps, on peut utiliser un système comprenant un manchon présentant des moyens d'accroche de la pompe et une jupe pourvue de moyens de fixation dudit manchon sur ledit réservoir.To ensure the positioning and fixing of the pump relative to the body, it is possible to use a system comprising a sleeve having means for attaching the pump and a skirt provided with means for fixing said sleeve to said reservoir.

Le système de fixation comprend en outre une frette montée en coulissement autour de la jupe entre une position haute dans laquelle les moyens d'accroche sont libres de sorte à permettre le positionnement de ladite jupe autour du col et une position basse dans laquelle les moyens d'accroche sont contraints par ladite frette pour assurer la fixation étanche du manchon sur ledit col du réservoir.The fixing system further comprises a hoop mounted to slide around the skirt between a high position in which the hooking means are free so as to allow the positioning of said skirt around the neck and a low position in which the means of 'grip are constrained by said hoop to ensure the tight fixing of the sleeve on said neck of the reservoir.

Le problème qui se pose avec l'utilisation de tels systèmes selon l'art antérieur est que la fixation de la pompe est inamovible. Or, pour des problèmes écologiques de recyclage en fin de vie du flacon, il est d'actualité de faciliter la séparation de la pompe constituée essentiellement de matières plastiques et métalliques, du réservoir réalisé souvent dans une catégorie de matière plastique différente ou bien en verre.The problem which arises with the use of such systems according to the prior art is that the fixing of the pump is irremovable. However, for ecological recycling problems at the end of the bottle's life, it is topical to facilitate the separation of the pump, which is essentially made up of plastics and metals, from the reservoir, which is often made in a different category of plastic or else in glass. .

Pour résoudre ce problème, on connaît l'utilisation de manchons qui sont montés par vissage sur le col fileté. Toutefois, les parfumeurs, cosméticiens ou pharmaciens ne souhaitent généralement pas que les manchons soient dévissables et revissables facilement par l'utilisateur, notamment pour des raisons de dégradation possible du produit distribué ou de changement d'affectation du flacon.To solve this problem, the use of sleeves is known which are mounted by screwing on the threaded neck. However, perfumers, cosmeticians or pharmacists generally do not want the sleeves to be unscrewable and easily screwed back on by the user, in particular for reasons of possible degradation of the product dispensed or of changing the use of the bottle.

De plus, les manchons vissables laissent obligatoirement un jeu fonctionnel inesthétique entre le bas dudit manchon et les épaules du corps. Egalement, leur vissage sur les lignes de remplissage est lent et donc coûteux. Par ailleurs, les manchons vissables doivent être vissés sur les lignes de remplissage selon un couple bien précis devant parfaitement être respecté pour assurer leur étanchéité sur le col.In addition, the screwable sleeves necessarily leave an unsightly functional play between the bottom of said sleeve and the shoulders of the body. Also, their screwing on the filling lines is slow and therefore expensive. Moreover, the screwable sleeves must be screwed onto the filling lines according to a very precise torque which must be perfectly respected to ensure their tightness on the neck.

On connaît également l'utilisation de manchons qui sont encliquetés dans le col du réservoir. Mais cette solution en tant que telle n'est pas satisfaisante car elle ne présente aucune aide au déclipsage, ce qui est de nature à décourager l'utilisateur de séparer les composants.The use of sleeves is also known which are snapped into the neck of the reservoir. But this solution as such is not satisfactory because it does not offer any assistance in unclipping, which is likely to discourage the user from separating the components.

L'invention vise à perfectionner l'art antérieur en proposant notamment un système de fixation rapide d'une pompe sur le col d'un réservoir tout en permettant leur séparation intuitive et quasi irréversible à fin de recyclage, et ce en présentant une esthétique avantageuse et une simplicité de montage/démontage.The invention aims to improve the prior art by proposing in particular a system for rapid attachment of a pump to the neck of a reservoir while allowing their intuitive and almost irreversible separation for recycling, and this while having an advantageous appearance. and ease of assembly / disassembly.

Résumé de l'inventionSummary of the invention

La présente invention a pour objectif de pallier les différents inconvénients énoncés ci-dessus, au moyen d'un ensemble de distribution d'un produit fluide, comprenant de façon classique :

  • un réservoir de conditionnement du produit, constitué d'un corps surmonté d'un col définissant une ouverture supérieure ;
  • un système de distribution du produit;
  • un dispositif de fixation du système de distribution au réservoir.
The object of the present invention is to overcome the various drawbacks stated above, by means of an assembly for dispensing a fluid product, conventionally comprising:
  • a container for packaging the product, consisting of a body surmounted by a neck defining an upper opening;
  • a product distribution system;
  • a device for fixing the distribution system to the tank.

Ledit dispositif de fixation consiste en une seule pièce présentant :

  • des moyens de solidarisation sur le col du réservoir actionnés par un mouvement de translation axial ;
  • des moyens de désolidarisation par rapport au col du réservoir actionnés par un mouvement de rotation.
Said fixing device consists of a single part having:
  • securing means on the neck of the reservoir actuated by an axial translational movement;
  • separating means from the neck of the reservoir actuated by a rotational movement.

Autrement dit, une pièce unique intègre au moins lesdits moyens de solidarisation et lesdits moyens de désolidarisation. Par pièce « unique », on entend une pièce formée d'un seul bloc, sans partie amovible l'une par rapport à l'autre, au moins dans la ou les parties intégrant lesdits moyens de solidarisation et lesdits moyens de désolidarisation. Cependant, ladite pièce pourra aussi bien être mono matériau que formée de plusieurs matériaux, par exemple surmoulés les uns aux autres. De même, elle pourra aussi bien être formé d'un seul composant que de plusieurs composants, par exemple emmanchés les uns dans les autres.In other words, a single part integrates at least said securing means and said decoupling means. The term “single” part is understood to mean a part formed in a single block, with no part removable from one another, at least in the part or parts integrating said securing means and said decoupling means. However, said part could just as well be a single material as formed from several materials, for example overmolded to each other. Likewise, it could equally well be formed of a single component or of several components, for example fitted into each other.

Ce dispositif de fixation permet de monter le système de distribution sur le réservoir au moyen d'un unique mouvement linéaire, ce qui est simple à effectuer sur une ligne de production.This fixing device allows the distribution system to be mounted on the tank by means of a single linear movement, which is easy to perform on a production line.

En outre, ce dispositif de fixation permet de démonter le système de distribution par rapport au réservoir, suite à un simple mouvement de rotation du dispositif de fixation, effectué par l'utilisateur lorsqu'il désire séparer le réservoir du reste des éléments de l'ensemble de distribution dans un but de recyclage, une fois que tout le produit a été distribué et que le réservoir est vide. Ce mouvement de rotation est aisé pour l'utilisateur. Lors de cette rotation, il est possible que certaines pièces se déforment plastiquement, ou se cassent. Il s'agit d'un démontage unique, en gardant à l'esprit qu'il n'est pas souhaitable que l'utilisateur puisse remonter facilement le système de distribution sur le réservoir, comme expliqué précédemment.In addition, this fixing device makes it possible to remove the distribution system from the tank, following a simple rotational movement of the fixing device, carried out by the user when he wishes to separate the tank from the rest of the elements of the dispensing assembly for recycling, after all product has been dispensed and the tank is empty. This rotational movement is easy for the user. During this rotation, it is possible that some parts deform plastically, or break. This is a one-time dismantling, keeping in mind that it is undesirable for the user to be able to easily reassemble the dispensing system on the tank, as explained previously.

Enfin, par l'utilisation d'une pièce unique, il est plus facile d'emploi et plus robuste que des pièces amovibles les unes par rapport aux autres.Finally, by using a single part, it is easier to use and more robust than parts that can be removed from one another.

Selon un aspect de l'invention, ladite pièce unique pourra remplir à la fois le rôle de manchon et le rôle de frette. Elle assure ainsi une double fonction technique et esthétique.According to one aspect of the invention, said single part can fulfill both the role of sleeve and the role of hoop. It thus ensures a dual technical and aesthetic function.

Selon cet aspect de l'invention le dispositif de fixation permet de maintenir le système de distribution, notamment la pompe, par exemple par encliquetage, et d'être monté sur le col du réservoir, tout en assurant un certain esthétisme depuis l'extérieur, c'est-à-dire en cachant les éléments techniques du système de distribution.According to this aspect of the invention, the fixing device makes it possible to maintain the distribution system, in particular the pump, for example by snap-fitting, and to be mounted on the neck of the reservoir, while ensuring a certain aesthetic appearance from the outside, that is, by hiding the technical elements of the distribution system.

L'ensemble de distribution se caractérise à titre principal en ce que :

  • le col du réservoir comporte au moins une projection radiale, et présente un rebord annulaire autour de l'ouverture supérieure ;
  • le dispositif de fixation comporte une jupe présentant :
    • ∘ un jonc annulaire, correspondant auxdits moyens de solidarisation, coopérant avec ledit rebord annulaire du col pour l'encliquetage du dispositif de fixation sur le col du réservoir ;

The distribution set is mainly characterized in that:
  • the neck of the reservoir has at least one radial projection, and has an annular rim around the upper opening;
  • the fixing device comprises a skirt having:
    • ∘ an annular ring, corresponding to said securing means, cooperating with said annular rim of the neck for latching the fixing device onto the neck of the reservoir;
    • ∘ at least one ramp, corresponding to said uncoupling means, cooperating with said radial projection for unscrewing the fixing device relative to the neck of the reservoir.

Le col du réservoir présente ainsi une géométrie particulière, relativement simple, tandis que la jupe du dispositif de fixation présente une géométrie complexe, contrairement aux documents de l'art antérieur, tel que les documents WO2011/117526 , WO98/13293 , EP1050478 , ou encore WO2012/092989 . Dans le document WO98/13293 , le col du réservoir est complexe à réaliser car il comporte la majorité des éléments spécifiques à sa fixation avec le dispositif de fixation.The neck of the reservoir thus has a particular geometry, relatively simple, while the skirt of the fixing device has a complex geometry, unlike documents of the prior art, such as documents WO2011 / 117526 , WO98 / 13293 , EP1050478 , or WO2012 / 092989 . In the document WO98 / 13293 , the neck of the reservoir is complex to produce because it comprises the majority of the elements specific to its fixing with the fixing device.

Selon les différents modes de réalisation de l'invention, qui pourront être pris ensemble ou séparément :

  • le dispositif de fixation comporte des moyens d'indexage de sa position par rapport au réservoir. En effet, étant donné que le dispositif de fixation fait également office de frette, il est indispensable qu'il soit positionné et orienté correctement par rapport au réservoir, surtout si l'ensemble présente une forme spécifique. La géométrie de la partie basse de l'ensemble de distribution, à savoir le réservoir, doit correspondre à la géométrie de la partie haute de l'ensemble de distribution, à savoir le dispositif de fixation.
  • lesdits moyens d'indexage consistent en au moins une glissière prévue sur le dispositif de fixation, dans laquelle s'insère la projection radiale du col du réservoir lors de la solidarisation. Ainsi, la projection radiale sert à la fois à l'indexage du dispositif de fixation par rapport au réservoir lors du montage, et à la désolidarisation du dispositif de fixation par rapport au col du réservoir. Elle remplit deux fonctions.
  • ladite glissière est délimitée par deux parois latérales, s'étendant dans une direction axiale sur une longueur telle que la projection radiale se trouve toujours entre les deux parois latérales lorsque le dispositif de fixation est encliqueté dans le col du réservoir. Ces parois latérales peuvent être déformées plastiquement lors de la désolidarisation du dispositif de fixation par rapport au réservoir.

La projection radiale glisse le long de la rampe, suite au mouvement de rotation exercé par l'utilisateur, depuis une extrémité supérieure de la rampe, c'est-à-dire depuis une extrémité libre de l'une des deux branches du V, vers une extrémité inférieure de la rampe, c'est-à-dire vers le point de jonction entre les deux branches du V. La projection radiale est alors en contact avec la rampe depuis un point haut vers un point bas, ce qui entraîne la remontée de la jupe, et donc du dispositif de fixation, relativement au col du réservoir.

  • the fixing device comprises means for indexing its position relative to the reservoir. In fact, given that the fixing device also acts as a hoop, it is essential that it be positioned and oriented correctly with respect to the reservoir, especially if the assembly has a specific shape. The geometry of the lower part of the distribution assembly, namely the reservoir, must correspond to the geometry of the upper part of the distribution assembly, namely the fixing device.
  • said indexing means consist of at least one slide provided on the fixing device, into which is inserted the radial projection of the neck of the reservoir during solidarization. Thus, the radial projection serves both for indexing the fixing device with respect to the reservoir during assembly, and for detaching the fixing device with respect to the neck of the reservoir. It performs two functions.
  • said slideway is delimited by two side walls, extending in an axial direction over a length such that the radial projection is always located between the two side walls when the fixing device is snapped into the neck of the reservoir.

  • the radial projection has a contact zone with the edge of the ramp, said contact zone being bevelled. This bevel makes it possible to slide more easily on the edge of the ramp, and above all makes it possible to push on the ramp so as to move it away from the neck of the tank. It induces a radial force, which causes the skirt to move apart radially, which also causes the ring to move away from the rim of the neck, causing the skirt to unclip when it is raised.

Description détailléedetailed description

En relation avec les figures, on décrit ci-dessous un ensemble de distribution destiné à contenir un produit fluide en vue de sa distribution. Dans des exemples particuliers, le produit peut être un liquide ou une crème, par exemple un parfum, pour une application cosmétique ou pharmaceutique.In relation to the figures, a dispensing assembly intended to contain a fluid product with a view to its dispensing is described below. In particular examples, the product can be a liquid or a cream, for example a perfume, for cosmetic or pharmaceutical application.

L'ensemble de distribution comprend un réservoir 2, tel qu'illustré en figure 2, qui peut être formé en matériau rigide, notamment en verre ou en matériaux plastiques, pour définir un réservoir 2 de conditionnement du produit.The dispensing assembly comprises a reservoir 2, as illustrated in figure 2 , which can be formed from a rigid material, in particular from glass or from plastic materials, to define a reservoir 2 for packaging the product.

Ce réservoir 2 consiste en un corps 3 surmonté par un col 4 formé d'une seule pièce avec le corps 3, en définissant une ouverture supérieure 7 pour le réservoir 2.This reservoir 2 consists of a body 3 surmounted by a neck 4 formed integrally with the body 3, defining an upper opening 7 for the reservoir 2.

Comme illustré en figure 8, cet ensemble de distribution comprend également un système de distribution du produit, par exemple une pompe 16 montée dans l'ouverture supérieure 7 du réservoir 2. Cette pompe 16 coopère avec un bouton-poussoir 17 équipé d'un orifice de distribution. Selon une réalisation connue, le bouton 17 actionne en translation réversible un piston de la pompe 16 pour l'aspiration d'une dose de produit dans le réservoir 2 et pour sa distribution.As shown in figure 8 , this dispensing assembly also comprises a product dispensing system, for example a pump 16 mounted in the upper opening 7 of the reservoir 2. This pump 16 cooperates with a push-button 17 equipped with a dispensing orifice. According to a known embodiment, the button 17 actuates in reversible translation a piston of the pump 16 for the suction of a dose of product in the reservoir 2 and for its distribution.

Pour pouvoir positionner et fixer ce système de distribution sur et/ou dans le réservoir 2, il est prévu un dispositif de fixation 1 auquel s'accroche ici la pompe 16, et qui vient se fixer sur le col 4 du réservoir 2. Ce dispositif de fixation 1 de la pompe 16 s'apparente ainsi à un manchon traditionnel.In order to be able to position and fix this dispensing system on and / or in the reservoir 2, a fixing device 1 is provided to which the pump 16 is attached here, and which is attached to the neck 4 of the reservoir 2. This device fixing 1 of the pump 16 is thus similar to a traditional sleeve.

Ce dispositif de fixation 1 comporte préférentiellement une paroi périphérique 8 externe de décoration permettant de cacher ses parties fonctionnelles ainsi que le système de distribution qui y est logé, hormis le bouton-poussoir 17 qui lui doit rester accessible par l'utilisateur et donc apparent au moins en partie. Ce dispositif de fixation 1 s'apparente ainsi également à une frette traditionnelle.This fixing device 1 preferably comprises an external peripheral wall 8 for decoration making it possible to hide its functional parts as well as the distribution system housed therein, except for the push-button 17 which must remain accessible to it by the user and therefore visible to the user. less in part. This fixing device 1 is thus also similar to a traditional hoop.

Ce dispositif de fixation 1 consiste en une unique pièce par exemple une pièce plastique obtenue par moulage.This fixing device 1 consists of a single part, for example a plastic part obtained by molding.

Le dispositif de fixation 1 coopère avec le col 4 du réservoir 2 pour son montage et son démontage.The fixing device 1 cooperates with the neck 4 of the reservoir 2 for its assembly and disassembly.

En l'espèce, pour le montage, le dispositif de fixation 1 est solidarisé au col 4 du réservoir 2 par encliquetage, c'est-à-dire par un mouvement de translation axiale, simple à réaliser sur une ligne de production. Le dispositif de fixation 1 est ainsi « claqué » sur le col 4 du réservoir 2.In this case, for assembly, the fixing device 1 is secured to the neck 4 of the reservoir 2 by snap-fastening, that is to say by an axial translational movement, easy to achieve on a production line. The fixing device 1 is thus “slammed” onto the neck 4 of the reservoir 2.

Pour le démontage, le dispositif de fixation 1 est désolidarisé du col 4 du réservoir 2 par dévissage, c'est-à-dire par un mouvement de rotation, simple à réaliser par un utilisateur, lorsque le réservoir 2 est vide et qu'il souhaite recycler le réservoir 2, notamment si ce dernier est en verre et que le système de distribution est en plastique. Il est alors nécessaire de pouvoir aisément séparer le réservoir 2 du système de distribution.For disassembly, the fixing device 1 is separated from the neck 4 of the reservoir 2 by unscrewing, that is to say by a rotational movement, simple to perform by a user, when the reservoir 2 is empty and it wishes to recycle the tank 2, in particular if the latter is made of glass and the distribution system is made of plastic. It is then necessary to be able to easily separate the reservoir 2 from the distribution system.

Le dispositif de fixation 1 est représenté sur les figures 1, 3, 4, et présente un axe central. On pourra d'ailleurs remarquer que, aux figures 3 ainsi que 5 à 7, la paroi périphérique n'a pas été représentée afin de mieux voir l'intérieur du dispositif de fixation.The fastening device 1 is shown in the figures 1 , 3, 4 , and has a central axis. We can also notice that, at figures 3 as well as 5 to 7, the peripheral wall has not been shown in order to better see the interior of the fixing device.

Il comporte une jupe 14 interne d'allure cylindrique, comportant un jonc 13 annulaire dirigé vers l'intérieur, et comportant également une succession de rampes 11 au niveau de son extrémité inférieure dirigée vers le col 4 du réservoir 2. Ces rampes 11 donnent une allure dentelée à la jupe 14. Chaque rampe 11 a une forme en V. Dans le mode de réalisation présenté sur les figures, il existe quatre rampes 11 en V réparties de manière homogène sur le pourtour de la jupe 14. Pour que l'invention fonctionne, une seule rampe 11 est nécessaire.It comprises an internal skirt 14 of cylindrical appearance, comprising an annular ring 13 directed inwards, and also comprising a succession of ramps 11 at its lower end directed towards the neck 4 of the reservoir 2. These ramps 11 give a serrated appearance to the skirt 14. Each ramp 11 has a V-shape. In the embodiment shown in the figures, there are four V-shaped ramps 11 distributed homogeneously around the periphery of the skirt 14. So that the invention works, only one ramp 11 is needed.

Ces rampes 11 présentent chacune un rebord 12 qui consiste en une première surface de contact. De préférence, ce rebord 12 est chanfreiné vers l'intérieur de la jupe 14. Il a alors un profil d'extrémité d'allure triangulaire. Il peut également être chanfreiné de part et d'autre, lui conférant un profil d'extrémité en pointe.These ramps 11 each have a flange 12 which consists of a first contact surface. Preferably, this rim 12 is chamfered towards the inside of the skirt 14. It then has an end profile of triangular appearance. It can also be chamfered on either side, giving it a pointed end profile.

Entre chaque rampe 11 se trouve une glissière 9 se déployant parallèlement à l'axe central du dispositif de fixation 1. Ces glissières 9 sont constituées d'un fond et de deux parois latérales 10. Leurs fonctions seront expliquées plus loin dans la description. Pour que l'invention fonctionne, une seule glissière 9 est nécessaire.Between each ramp 11 is a slide 9 which deploys parallel to the central axis of the fixing device 1. These slides 9 consist of a bottom and two side walls 10. Their functions will be explained later in the description. For the invention to work, only one slide 9 is necessary.

Le dispositif de fixation 1 comporte également ici une cheminée 15 centrale s'étendant à l'intérieur de la jupe 14 et connectée à la jupe 14 par une nervure centrale 19. Cette cheminée 15 centrale permet d'accueillir la pompe 16 du système de distribution. Le tronçon inférieur de la cheminée 15 est inséré à l'intérieur du col 4 du réservoir 2, et présente une épaisseur s'affinant vers l'extrémité de manière à bien pouvoir se plaquer contre la paroi intérieure du col 4 du réservoir 2, afin de réaliser une étanchéité entre le réservoir 2 et le dispositif de fixation 1.The fixing device 1 here also comprises a central chimney 15 extending inside the skirt 14 and connected to the skirt 14 by a central rib 19. This central chimney 15 makes it possible to accommodate the pump 16 of the distribution system. . The lower section of the chimney 15 is inserted inside the neck 4 of the tank 2, and has a thickness that becomes thinner towards the end so as to be able to be pressed against the inner wall of the neck 4 of the tank 2, in order to to provide a seal between the tank 2 and the fixing device 1.

Enfin, le dispositif de fixation 1 comporte une paroi périphérique 8 externe s'étendant sur toute la hauteur de la pièce, afin de lui conférer un aspect esthétique extérieur uniforme, et que tous les éléments techniques à l'intérieur du dispositif de fixation 1 soient cachés, en l'espèce les glissières 9, les rampes 11, la jupe 14, la cheminée 15, et le système de distribution. De préférence, cette paroi périphérique 8 peut être de forme carronde, les glissières 9 se situant alors dans les quatre coins intérieurs de cette paroi périphérique 8, et les rampes 11 se situant au voisinage de chaque côté de la paroi périphérique 8. Cette paroi périphérique 8 peut prendre toute autre forme, par exemple cylindrique, ou carrée ou rectangulaire, ou triangulaire etc.Finally, the fixing device 1 comprises an outer peripheral wall 8 extending over the entire height of the room, in order to give it a uniform exterior aesthetic appearance, and that all the technical elements inside the fixing device 1 are hidden, in this case the slides 9, the ramps 11, the skirt 14, the chimney 15, and the distribution system. Preferably, this peripheral wall 8 may be of square shape, the slides 9 then being located in the four interior corners of this peripheral wall 8, and the ramps 11 being located in the vicinity of each side of the peripheral wall 8. This peripheral wall 8 can take any other shape, for example cylindrical, or square or rectangular, or triangular etc.

La paroi périphérique 8 est reliée à la jupe 14 via des nervures périphériques 20.The peripheral wall 8 is connected to the skirt 14 via peripheral ribs 20.

Le bouton poussoir 17 est inséré entre la paroi périphérique 8 et la jupe 14 du dispositif de fixation 1.The push button 17 is inserted between the peripheral wall 8 and the skirt 14 of the fixing device 1.

Pour pouvoir monter ce dispositif de fixation 1 sur le réservoir 2, le col 4 du réservoir 2 est doté d'un rebord annulaire 6 localisé au niveau de son extrémité libre, et définissant l'ouverture supérieure 7. Ce rebord annulaire 6 coopère avec le jonc 13 prévu dans la jupe 14 du dispositif de fixation 1. En l'espèce, au moment du montage, le dispositif de fixation 1 est disposé au-dessus du col 4 du réservoir 2, puis est enfoncé sur le col 4 du réservoir 2 jusqu'à encliquetage, c'est-à-dire jusqu'à ce que le jonc 13 de la jupe 14 passe sous le rebord annulaire 6 du col 4 du réservoir 2. Il s'agit donc d'un montage rapide, en force. Lors du montage, le col 4 du réservoir 2 est inséré entre la jupe 14 et la cheminée 15 du dispositif de fixation 1.In order to be able to mount this fixing device 1 on the reservoir 2, the neck 4 of the reservoir 2 is provided with an annular rim 6 located at its free end, and defining the upper opening 7. This annular rim 6 cooperates with the ring 13 provided in the skirt 14 of the fixing device 1. In this case, at the time of assembly, the fixing device 1 is placed above the neck 4 of the reservoir 2, then is pushed onto the neck 4 of the reservoir 2 until it clicks, that is to say until the ring 13 of the skirt 14 passes under the annular rim 6 of the neck 4 of the tank 2. This is therefore a rapid assembly, by force . During assembly, the neck 4 of the tank 2 is inserted between the skirt 14 and the chimney 15 of the fixing device 1.

Pour pouvoir monter et démonter le dispositif de fixation 1 par rapport au réservoir 2, le col 4 du réservoir 2 est doté d'une projection radiale 5 située entre le rebord annulaire 6 du col 4 et le corps 3 du réservoir 2. De préférence, et dans le mode de réalisation représenté, il existe deux projections radiales 5 diamétralement opposées.In order to be able to mount and remove the fixing device 1 relative to the reservoir 2, the neck 4 of the reservoir 2 is provided with a radial projection 5 situated between the annular rim 6 of the neck 4 and the body 3 of the reservoir 2. Preferably, and in the illustrated embodiment, there are two diametrically opposed radial projections.

Lors du montage du dispositif de fixation 1 sur le col 4, chaque projection radiale 5 doit d'abord rentrer dans une glissière 9, ce qui permet d'orienter correctement le dispositif de fixation 1 par rapport au réservoir 2. En effet, dans le mode de réalisation présenté, le réservoir 2 a une forme carronde, tout comme la paroi périphérique 8 du dispositif de fixation 1. Il est donc nécessaire que la paroi périphérique 8 carronde du dispositif de fixation 1 puisse être alignée avec la paroi périphérique caronde du corps 3 du réservoir 2. Pour cela, les glissières 9 et les projections radiales 5 ont un positionnement très précis dans le dispositif de fixation 1 et sur le col 4 du réservoir 2. En l'espèce, les projections radiales 5 s'étendent chacune en direction d'un coin de la forme carronde du corps 3 du réservoir 2, les glissières 9 étant elles aussi logées au niveau des coins de la forme carronde du dispositif de fixation 1.When mounting the fixing device 1 on the neck 4, each radial projection 5 must first enter a slide 9, which makes it possible to correctly orient the fixing device 1 with respect to the reservoir 2. Indeed, in the embodiment shown, the reservoir 2 has a square shape, just like the peripheral wall 8 of the fixing device 1. It is therefore necessary that the square peripheral wall 8 of the fixing device 1 can be aligned with the round peripheral wall of the body 3 of the reservoir 2. For this, the slides 9 and the radial projections 5 have a very precise positioning in the fixing device 1 and on the neck 4 of the reservoir 2. In this case, the radial projections 5 each extend in direction of a corner of the square shape of the body 3 of the tank 2, the slides 9 also being housed at the level of the corners of the square shape of the fixing device 1.

Une fois que le dispositif de fixation 1 est correctement orienté par rapport au réservoir 2, le dispositif de fixation 1 continue sa course en direction du réservoir 2 et les projections radiales 5 coulissent à l'intérieur des glissières 9 jusqu'à l'encliquetage. Chaque projection radiale 5 est retenue à l'intérieur de la glissière 9 entourée par les deux parois latérales 10 de la glissière 9.Once the fixing device 1 is correctly oriented with respect to the reservoir 2, the fixing device 1 continues its course in the direction of the reservoir 2 and the radial projections 5 slide inside the slides 9 until they click into place. Each radial projection 5 is retained inside the slide 9 surrounded by the two side walls 10 of the slide 9.

Ces glissières 9 servent ainsi à l'indexage du dispositif de fixation 1 par rapport au réservoir 2, ainsi qu'au guidage du dispositif de fixation 1 par rapport au réservoir 2 lors de son montage.These slides 9 thus serve for indexing the fixing device 1 with respect to the reservoir 2, as well as for guiding the fixing device 1 with respect to the reservoir 2 during its assembly.

Lors du démontage du dispositif de fixation 1 par rapport au col 4 du réservoir 2, les projections radiales 5 coopèrent avec les rampes 11.When removing the fixing device 1 from the neck 4 of the reservoir 2, the radial projections 5 cooperate with the ramps 11.

Sur la figure 5, le dispositif de fixation 1 est encliqueté sur le col 4 du réservoir 2. Chaque projection radiale 5 se trouve insérée à l'intérieur d'une glissière 9.On the figure 5 , the fixing device 1 is snapped onto the neck 4 of the reservoir 2. Each radial projection 5 is inserted inside a slide 9.

Sur la figure 6, l'utilisateur commence à exercer un mouvement de rotation sur le dispositif de fixation 1 de manière à le faire tourner par rapport au réservoir 2. Lors de ce mouvement, les projections radiales 5 sortent des glissières 9 et viennent en contact avec les rampes 11. Lors de cette phase, il est possible que les parois latérales 10 se déforment élastiquement ou plastiquement.On the figure 6 , the user begins to exert a rotational movement on the fixing device 1 so as to make it rotate relative to the reservoir 2. During this movement, the radial projections 5 come out of the slides 9 and come into contact with the ramps 11 During this phase, it is possible for the side walls 10 to deform elastically or plastically.

Les projections radiales 5 présentent une surface supérieure 21 dirigée vers le haut du réservoir 2, c'est-à-dire dirigée vers le dispositif de fixation 1. Au moins un bord 18 de cette surface supérieure 21 est biseauté. Ce bord biseauté 18 correspond à une 2e surface de contact, apte à coulisser sur la première surface de contact correspondant aux rebords 12 chanfreinés des rampes 11, et plus précisément à la partie chanfreinée dirigée vers l'intérieur de la jupe 14. De préférence, les trois bords délimitant la surface supérieure 21 sont biseautés.The radial projections 5 have an upper surface 21 directed towards the top of the reservoir 2, that is to say directed towards the fixing device 1. At least one edge 18 of this upper surface 21 is bevelled. This beveled edge 18 corresponds to a 2 nd contact surface, able to slide on the first contact surface corresponding to the chamfered edges 12 of the ramps 11, and more precisely to the chamfered part directed towards the inside of the skirt 14. Preferably , the three edges defining the upper surface 21 are bevelled.

En effet, lors du mouvement de rotation, un bord biseauté 18 de la projection radiale 5 entre en contact contre la partie chanfreinée 12 (vers l'intérieur de la jupe14) de la rampe 11, au voisinage d'une extrémité supérieure de la rampe 11, c'est-à-dire un point haut de la rampe 11. Au fur et à mesure du dévissage, le bord biseauté 18 de la projection radiale 5 coulisse le long de la partie chanfreinée 12 de la rampe 11 en direction d'une extrémité inférieure de la rampe 11, c'est-à-dire un point bas de la rampe 11, comme illustré en figure 7. Le décalage entre la partie supérieure et la partie inférieure de la rampe 11 entraîne un mouvement de translation axiale du dispositif de fixation 1 par rapport au réservoir 2, le faisant ainsi remonter par rapport au réservoir 2.Indeed, during the rotational movement, a bevelled edge 18 of the radial projection 5 comes into contact against the chamfered part 12 (towards the inside of the skirt 14) of the ramp 11, in the vicinity of an upper end of the ramp. 11, that is to say a high point of the ramp 11. As the unscrewing progresses, the bevelled edge 18 of the radial projection 5 slides along the chamfered part 12 of the ramp 11 in the direction of a lower end of the ramp 11, that is to say a low point of the ramp 11, as illustrated in figure 7 . The offset between the upper part and the lower part of the ramp 11 causes an axial translational movement of the fixing device 1 relative to the reservoir 2, thus causing it to rise relative to the reservoir 2.

Par ailleurs, le contact entre le bord biseauté 18 de la projection radiale 5 et la partie chanfreinée 12 de la rampe 11 entraîne un éloignement de la rampe 11 par rapport au col 4 du réservoir 2. En effet, le contact entre les différentes parties inclinées a tendance à faire décoller la rampe 11, c'est-à-dire à la pousser radialement vers l'extérieur. Ainsi, le diamètre intérieur de la jupe 14 sur laquelle sont formées les rampes 11 ainsi que le jonc 13 de clipsage augmente, ce qui favorise le déclipsage entre le jonc 13 de la jupe 14 et le rebord annulaire 6 du col 4. La figure 7 illustre le dispositif de fixation 1 désencliqueté par rapport au col 4 du réservoir 2. Lors de cette phase, il est possible que les rampes se déforment plastiquement, ou se fissurent.Furthermore, the contact between the bevelled edge 18 of the radial projection 5 and the chamfered part 12 of the ramp 11 causes the ramp 11 to move away from the neck 4 of the reservoir 2. In fact, the contact between the different inclined parts tends to take off the ramp 11, that is to say to push it radially outwards. Thus, the inside diameter of the skirt 14 on which the ramps 11 are formed as well as the clipping ring 13 increases, which promotes unclipping between the ring 13 of the skirt 14 and the annular rim 6 of the neck 4. The figure 7 illustrates the fastening device 1 unclipped with respect to the neck 4 of the reservoir 2. During this phase, it is possible that the ramps deform plastically, or crack.

Il est à noter que le désencliquetage aurait également lieu même si la projection radiale 5 n'avait pas de bord biseauté, et/ou même si la rampe 11 n'avait pas de rebord chanfreiné. La rotation serait alors un peu plus « dure » à obtenir pour l'utilisateur.It should be noted that the unclipping would also take place even if the radial projection 5 did not have a bevelled edge, and / or even if the ramp 11 did not have a bevelled edge. The rotation would then be a little "harder" for the user to obtain.

Au final, le dispositif de fixation 1 a un mouvement hélicoïdal lors de son démontage, puisque le mouvement de rotation induit par l'utilisateur est combiné avec le mouvement de translation axiale induit par le contact entre les projections radiales 5 et les rampes 11.In the end, the fixing device 1 has a helical movement during its dismantling, since the rotational movement induced by the user is combined with the axial translational movement induced by the contact between the radial projections 5 and the ramps 11.

Les configurations montrées aux figures citées ne sont que des exemples possibles, nullement limitatifs, de l'invention qui englobe au contraire les variantes de formes et de conceptions à la portée de l'homme de l'art.The configurations shown in the figures cited are only possible examples, in no way limiting, of the invention which, on the contrary, encompasses the variants of shapes and designs within the reach of those skilled in the art.
