Description

Domaine technique de l'inventionTechnical field of the invention

L'invention concerne un système de fixation d'une pompe de distribution de produit fluide. L'invention concerne également le flacon de produit fluide associé.The invention relates to a system for fixing a fluid dispensing pump. The invention also relates to the associated fluid product bottle.

Dans le cadre de l'invention, le produit fluide peut être un produit cosmétique, un produit pharmaceutique ou tout autre produit.In the context of the invention, the fluid product can be a cosmetic product, a pharmaceutical product or any other product.

Arrière-plan techniqueTechnical background

Les flacons de produit fluide comprennent classiquement un réservoir pour le produit fluide surmonté dans sa partie supérieure d'un col rigide délimitant une ouverture dans laquelle est inséré le système de distribution du produit fluide.Fluid product bottles conventionally comprise a reservoir for the fluid product surmounted in its upper part by a rigid neck delimiting an opening in which the fluid product distribution system is inserted.

Le système de distribution comprend une pompe qui peut être actionnée par un utilisateur au moyen d'un bouton poussoir, ce qui permet de distribuer une dose du produit fluide, notamment sous forme de spray.The distribution system comprises a pump which can be actuated by a user by means of a push button, which makes it possible to dispense a dose of the fluid product, in particular in the form of a spray.

Le système de distribution comprend en outre des moyens de fixation et d'étanchéité qui permettent son maintien au niveau du col et au besoin d'isoler le réservoir de l'environnement extérieur. Parmi les différentes configurations existantes, on distingue les moyens de fixation permettant une fixation définitive du système de distribution au niveau du col, des moyens de fixation nécessitant un effort seuil pour déverrouiller lesdits moyens de fixation et des moyens de fixation amovibles. L'utilisation d'une configuration plutôt qu'une autre dépend de la problématique adressée.The distribution system further comprises fixing and sealing means which allow it to be maintained at the neck and, if necessary, to isolate the reservoir from the external environment. Among the different existing configurations, a distinction is made between the fixing means allowing a definitive fixing of the distribution system at the level of the neck, fixing means requiring a threshold force to unlock said fixing means and removable fixing means. The use of one configuration rather than another depends on the problem addressed.

On connait de l'art antérieur un système de fixation d'une pompe sur un col d'un réservoir configuré pour faciliter le recyclage du système une fois démonté. Le système de fixation est muni d'un manchon, un collet monté autour du manchon et apte à se déplacer partiellement selon un mouvement hélicoïdal autour dudit manchon par l'actionnement d'une frette. Le manchon est configuré de sorte que le dévissage du système de fixation requiert l'application d'un effort seuil par l'utilisateur, grâce à la présence d'ergots. Une fois qu'une position de démontage est atteinte, le collet reste en position de démontage sur le manchon tandis que la pompe peut être retirée, ce qui permet soit un recyclage du flacon, débarrassé de la pompe, soit à l'utilisateur de remplir le réservoir de nouveau. Pour remonter la pompe, c'est-à-dire la replacer en position d'utilisation, l'utilisateur doit nécessairement revisser le collet. Cependant, les ergots permettant de calibrer l'effort à fournir pour le dévissage sont configurés de telle sorte que le remontage est quasi impossible ou très difficile. En outre, même si l'utilisateur arrivait à replacer la pompe, cela devrait passer, comme indiqué, par un mouvement de vissage.There is known from the prior art a system for fixing a pump on a neck of a tank configured to facilitate recycling of the system once dismantled. The fastening system is provided with a sleeve, a collar mounted around the sleeve and able to partially move in a helical movement around said sleeve by actuating a hoop. The sleeve is configured so that the unscrewing the fastening system requires the application of a threshold force by the user, thanks to the presence of pins. Once a disassembly position is reached, the collar remains in the disassembly position on the sleeve while the pump can be removed, which allows either a recycling of the bottle, removed from the pump, or the user to fill the tank again. To reassemble the pump, that is to put it back in the position of use, the user must necessarily screw the collar back on. However, the pins for calibrating the effort to be provided for unscrewing are configured so that reassembly is almost impossible or very difficult. In addition, even if the user could replace the pump, it should pass, as indicated, by a screwing movement.

Résumé de l'inventionSummary of the invention

La présente invention fournit un système de fixation qui permet, après remplissage du réservoir, de remonter la pompe par vissage mais également et surtout par simple appui sur la frette et propose à cet égard un système de fixation d'une pompe de distribution sur le col d'un réservoir contenant du produit fluide, ledit système comprenant :

  • un manchon comprenant des moyens de fixation sur ledit col et des moyens d'accroche de la pompe ;
  • un collet d'articulation, ledit collet d'articulation et le manchon étant montés mobiles l'un par rapport à l'autre entre une position de fin de course et une position de début de course;
  • une frette configurée pour déplacer ledit collet d'articulation entre une position haute de démontage, dans laquelle lesdits moyens de fixation sont libres, et une position basse d'utilisation, dans laquelle lesdits moyens de fixation sont en prise autour dudit col.
The present invention provides a fixing system which allows, after filling the tank, to reassemble the pump by screwing but also and above all by simple pressing on the hoop and proposes in this regard a system for fixing a dispensing pump on the neck of a reservoir containing fluid, said system comprising:
  • a sleeve comprising means for fixing to said neck and means for attaching the pump;
  • an articulation collar, said articulation collar and the sleeve being mounted movable relative to one another between an end of travel position and a start of travel position;
  • a hoop configured to move said articulation collar between a high disassembly position, in which said fixing means are free, and a low position of use, in which said fixing means are engaged around said neck.

Ce système de fixation est caractérisé en ce que lesdites positions de début et de fin de course sont situées de sorte que le collet d'articulation soit apte à passer de la position haute de démontage vers la position basse d'utilisation par translation.This fastening system is characterized in that said start and end of travel positions are located so that the articulation collar is capable of passing from the high disassembly position to the low position of use by translation.

L'idée de l'invention est de permettre le remontage de la pompe par une gestuelle simple, à savoir, une translation tout en conservant les avantages d'un système de fixation comprenant un manchon, un collet d'articulation et une frette. À cet égard, les positions de début et de fin de course sont avantageusement situées dans le prolongement axial l'une de l'autre de sorte que le collet d'articulation soit capable de glisser depuis le logement de fin de course vers le logement de début de course par translation et que le remontage de la pompe soit aussi possible par simple appui de l'utilisateur. En outre, une fois remis en place, le système est à nouveau en position de début de course et un même cycle de démontage/remontage peut être recommencé.The idea of the invention is to allow reassembly of the pump by a simple gesture, namely, translation while retaining the advantages of a fixing system comprising a sleeve, an articulation collar and a hoop. AT In this regard, the start and end positions are advantageously located in the axial extension of each other so that the articulation collar is able to slide from the end-of-travel housing towards the start housing stroke by translation and that reassembly of the pump is also possible by simple user support. In addition, once replaced, the system is again in the start of race position and the same disassembly / reassembly cycle can be started again.

Description détaillée de l'inventionDetailed description of the invention

En référence à la figure 1, l'invention concerne un flacon de distribution d'un produit fluide comprenant un réservoir 3 et une tête de distribution 1 du produit fluide contenu dans le réservoir 3.With reference to the figure 1 , the invention relates to a dispensing bottle for a fluid product comprising a reservoir 3 and a dispensing head 1 for the fluid product contained in the reservoir 3.

Le produit fluide peut être un produit cosmétique, un produit pharmaceutique ou tout autre produit qui peut être utilement préservé dans un flacon. Le fluide peut être directement en contact avec le réservoir 3. Cela dit, le fluide peut être compris dans une poche souple située au sein dudit réservoir 3 de sorte qu'il n'est pas en contact avec le réservoir 3 mais avec ladite poche souple.The fluid product can be a cosmetic product, a pharmaceutical product or any other product which can be usefully preserved in a bottle. The fluid can be directly in contact with the reservoir 3. That said, the fluid can be included in a flexible pocket located within said reservoir 3 so that it is not in contact with the reservoir 3 but with said flexible pocket .

Le réservoir 3 peut être indifféremment rigide ou déformable. Ceci étant, le réservoir 3 comprend, au niveau d'une partie supérieure, un col 4 et une ouverture 5 formée dans ledit col 4. Le col 4 est de préférence rigide. Il forme une gorge 7 avec le réservoir 3 et un chant périphérique 6 surmontant ladite gorge 7.The reservoir 3 can be either rigid or deformable. That said, the reservoir 3 comprises, at an upper part, a neck 4 and an opening 5 formed in said neck 4. The neck 4 is preferably rigid. It forms a groove 7 with the reservoir 3 and a peripheral edge 6 surmounting said groove 7.

La tête de distribution 1 est équipée d'une pompe de distribution 2 du produit fluide contenu dans le réservoir 3. En sortie de la pompe, le fluide distribué est en particulier liquide, visqueux ou pâteux. La pompe de distribution 2 comprend un corps s'étendant selon un axe longitudinal central X correspondant à un axe médian du flacon. Le corps est de forme tubulaire notamment de révolution. En utilisation, la pompe de distribution 2 est maintenue immobile au niveau du col 4 au moyen d'un système de fixation selon l'invention. Cela étant, la pompe de distribution 2 peut être retirée de cet emplacement au moyen dudit système de fixation, par exemple à des fins de remplissage du réservoir 3. Autrement dit, la pompe de distribution 2 est amovible.The dispensing head 1 is equipped with a dispensing pump 2 for the fluid product contained in the reservoir 3. At the outlet of the pump, the dispensed fluid is in particular liquid, viscous or pasty. The dispensing pump 2 comprises a body extending along a central longitudinal axis X corresponding to a median axis of the bottle. The body is of tubular shape in particular of revolution. In use, the distribution pump 2 is held stationary at the neck 4 by means of a fixing system according to the invention. However, the distribution pump 2 can be removed from this location by means of said fixing system, for example for filling the reservoir 3. In other words, the distribution pump 2 is removable.

Le système de fixation selon l'invention comprend un manchon 10 de fixation, un collet d'articulation 25 et une frette 30. Le collet d'articulation 25 et le manchon 10 sont montés mobiles l'un par rapport à l'autre entre une position de début de course PI (illustrée à la figure 1) et une position de fin de course PF (illustrée à la figure 3). La cinématique de déplacement dudit collet d'articulation 25 relativement audit manchon 10 sera mieux décrite par la suite. La frette 30 est quant à elle configurée pour actionner un déplacement dudit collet d'articulation 25 relativement audit manchon 10. Elle a également une fonction de décoration, sa surface externe étant visible de l'utilisateur.The fixing system according to the invention comprises a fixing sleeve 10, an articulation collar 25 and a hoop 30. The articulation collar 25 and the sleeve 10 are mounted movable relative to one another between a start position P I (illustrated in figure 1 ) and an end position P F (illustrated in figure 3 ). The kinematics of movement of said articulation collar 25 relative to said sleeve 10 will be better described below. The hoop 30 is in turn configured to actuate a displacement of said articulation collar 25 relative to said sleeve 10. It also has a decorative function, its external surface being visible to the user.

Dans le mode de réalisation illustré à la figure 1, le manchon 10 est de forme généralement cylindrique et s'étend selon l'axe X. Le manchon 10 est creux. Il délimite un volume intérieur vide servant essentiellement à accueillir la pompe de distribution 2. Pour autant la pompe 2 s'étend axialement au-delà des extrémités du manchon 10. Le manchon 10 est muni de moyens d'accroche 11 de la pompe de distribution 2. Les moyens d'accroche 11 permettent de maintenir la pompe 2 immobile au niveau du col 4, par exemple de façon étendue grâce à un joint 9.In the embodiment illustrated in figure 1 , the sleeve 10 is generally cylindrical in shape and extends along the axis X. The sleeve 10 is hollow. It delimits an empty internal volume essentially used to accommodate the distribution pump 2. However, the pump 2 extends axially beyond the ends of the sleeve 10. The sleeve 10 is provided with attachment means 11 of the distribution pump 2. The attachment means 11 make it possible to keep the pump 2 immobile at the level of the neck 4, for example in an extended manner thanks to a seal 9.

Le manchon 10 comprend une jupe 12 configurée pour venir en prise avec le col 4. À cet égard, la jupe 12 comprend une portion plane 14 apte à venir autour du chant périphérique 6, éventuellement en serrage. La jupe 12 comprend en outre des moyens de fixation 15 au col 4 s'étendant dans le prolongement de la portion plane 14.The sleeve 10 comprises a skirt 12 configured to come into engagement with the neck 4. In this regard, the skirt 12 comprises a flat portion 14 capable of coming around the peripheral edge 6, possibly in clamping. The skirt 12 also comprises means of attachment 15 to the neck 4 extending in the extension of the flat portion 14.

Préférentiellement, les moyens de fixation 15 consistent en des pattes souples aptes à effectuer des mouvements indépendamment les unes des autres. De préférence, les pattes souples 15 sont régulièrement espacées les unes des autres sur tout le pourtour de la jupe 12, c'est-à-dire que les pattes souples sont séparées les unes des autres par une distance constante. De préférence, également, les pattes souples 15 sont reliées à la portion plane 14 au moyen d'une portion charnière 15a. Elles adoptent alternativement une position de dégagement dans laquelle elles sont libres, c'est-à-dire qu'elles ne sont pas en prise avec le col 4 et une position d'engagement dans laquelle elles sont en prise avec ledit col 4. Les pattes souples 15 présentent, sur leurs faces internes, c'est-à-dire sur leurs faces tournées vers le col 4, une forme sensiblement complémentaire avec la forme de la gorge 7. Dans la configuration illustrée à la figure 1, les pattes souples 15 sont en position de dégagement, c'est-à-dire qu'elles ne sont pas engagées dans la gorge 7.Preferably, the fixing means 15 consist of flexible tabs capable of carrying out movements independently of each other. Preferably, the flexible tabs 15 are regularly spaced from each other around the entire periphery of the skirt 12, that is to say that the flexible tabs are separated from each other by a constant distance. Preferably also, the flexible tabs 15 are connected to the flat portion 14 by means of a hinge portion 15a. They alternately adopt a release position in which they are free, that is to say that they are not engaged with the neck 4 and an engagement position in which they are engaged with said neck 4. The flexible tabs 15 have, on their internal faces, that is to say on their faces facing the neck 4, a shape substantially complementary with the shape of the groove 7. In the configuration illustrated in the figure 1 , the flexible tabs 15 are in the release position, that is to say that they are not engaged in the groove 7.

Le manchon 10 comprend en outre un collet de guidage 16 ayant pour fonction principale de guider le collet d'articulation 25 dans ses mouvements. Le collet d'articulation 25 est plus précisément monté mobile autour du collet de guidage 16. En d'autres termes, il est apte à se déplacer relativement audit collet de guidage 16. Ledit collet de guidage 16 comprend des moyens de guidage dudit collet d'articulation 25, qui seront décrits plus en détail dans la suite. Le collet d'articulation 25, quant à lui, comprend des moyens de déplacement le long desdits moyens de guidage dudit collet de guidage 16. Le collet de guidage 16 et le collet d'articulation 25 forment donc un assemblage mécanique mobile. Le collet de guidage 16 est situé dans le prolongement longitudinal de la jupe 12.The sleeve 10 further comprises a guide collar 16 having the main function of guiding the articulation collar 25 in its movements. The articulation collar 25 is more precisely mounted mobile around the guide collar 16. In other words, it is able to move relative to said guide collar 16. Said guide collar 16 comprises means for guiding said collar articulation 25, which will be described in more detail below. The articulation collar 25, meanwhile, comprises means for moving along said guide means of said guide collar 16. The guide collar 16 and the articulation collar 25 therefore form a movable mechanical assembly. The guide collar 16 is located in the longitudinal extension of the skirt 12.

La frette 30 est de forme généralement cylindrique. Comme mentionné précédemment, elle est configurée pour actionner le déplacement dudit collet d'articulation 25. À cet égard, elle comprend une paroi intérieure 31 sur laquelle sont réparties angulairement des nervures 32. Les nervures sont plus précisément localisées sur une portion supérieure de la frette 30, le long de laquelle le collet d'articulation 25 est susceptible de se déplacer. Les nervures 32 permettent de solidariser la frette 30 et le collet d'articulation 25. En l'espèce, dans le mode de réalisation illustré aux figures 1 à 3, on peut constater que les nervures 32 (visibles sur la figure 1) sont incrustées dans une paroi extérieure 29 du collet d'articulation 25, ce qui permet le serrage et donc la solidarisation de la frette 30 autour du collet d'articulation 25. Cela permet ainsi de fiabiliser l'entraînement du collet d'articulation 25 par la frette 30.The hoop 30 is generally cylindrical in shape. As mentioned previously, it is configured to actuate the movement of said articulation collar 25. In this regard, it comprises an interior wall 31 on which ribs 32 are angularly distributed. The ribs are more precisely located on an upper portion of the hoop 30, along which the articulation collar 25 is capable of moving. The ribs 32 make it possible to secure the hoop 30 and the articulation collar 25. In the present case, in the embodiment illustrated in Figures 1 to 3 , we can see that the ribs 32 (visible on the figure 1 ) are embedded in an outer wall 29 of the articulation collar 25, which allows the tightening and therefore the joining of the hoop 30 around the articulation collar 25. This thus makes the drive of the articulation collar 25 more reliable. by hoop 30.

En outre, la frette 30 est configurée pour effectuer un mouvement de translation. Ce mouvement de translation de la frette 30 est rendu possible par la configuration du collet d'articulation 25 relativement à la jupe 12. Pour cela, la paroi extérieure 29 du collet d'articulation 25 est ici sensiblement alignée avec la portion plane 14 de la jupe 12 de sorte que la frette 30 est toujours maintenue en appui sur la paroi extérieure 29 et sur la portion plane 14. Incidemment, la frette 30 est ainsi capable de se déplacer longitudinalement, notamment entre une position proximale et une position distale relativement au manchon 10 en entraînant ledit collet d'articulation 25.In addition, the hoop 30 is configured to perform a translational movement. This translational movement of the hoop 30 is made possible by the configuration of the articulation collar 25 relative to the skirt 12. For this, the outer wall 29 of the articulation collar 25 is here substantially aligned with the flat portion 14 of the skirt 12 so that the hoop 30 is always held in abutment on the outer wall 29 and on the flat portion 14. Incidentally, the hoop 30 is thus able to move longitudinally, in particular between a proximal position and a distal position relative to the sleeve 10 by driving said articulation collar 25.

En étant ainsi configurée, la frette 30 est adaptée pour actionner le déplacement du collet d'articulation 25 entre une position haute PH de démontage et une position basse PB d'utilisation. Pour que le collet d'articulation 25 soit en mesure d'atteindre la position haute PH de démontage, la frette 30 doit se déplacer vers sa position distale. De même, pour que le collet d'articulation 25 puisse atteindre sa position basse d'utilisation PB, la frette 30 doit se déplacer vers sa position proximale. Il est à noter que dans la configuration illustrée sur la figure 1, le collet d'articulation 25 n'est ni en position haute PH de démontage ni en position basse PB d'utilisation mais dans une position avant montage initial.By being thus configured, the hoop 30 is adapted to actuate the movement of the articulation collar 25 between a high position P H for dismantling and a low position P B for use. In order for the articulation collar 25 to be able to reach the high disassembly position P H , the hoop 30 must move towards its distal position. Similarly, so that the articulation collar 25 can reach its low position of use P B , the hoop 30 must move towards its proximal position. It should be noted that in the configuration illustrated on the figure 1 , the articulation collar 25 is neither in the high position P H for dismantling nor in the low position P B for use but in a position before initial assembly.

En référence à la figure 2, le collet d'articulation 25 est dans la position basse PB d'utilisation. Lorsque le collet d'articulation 25 est dans cette position, le système de fixation est maintenu rigidement autour du col 4 et le flacon est prêt à être utilisé. En effet, dans cette configuration, la frette 30 étant située à la position proximale et donc complètement abaissée, sa paroi intérieure 31 exerce une pression radiale sur les moyens de fixation 15 qui sont en position d'engagement. Autrement dit, les moyens de fixation 15 sont en prise avec le col 4. En l'espèce, les faces extérieures des pattes souples 15 sont en alignement vertical avec la portion plane 14, tandis que leurs faces internes sont complètement engagées dans la gorge 7 du col. On peut remarquer que la gorge 7 comprend un évidement 8. L'évidement 8 forme un système anti-rotation du système de fixation dans lequel une ou plusieurs pattes 15 peuvent venir se loger.With reference to the figure 2 , the articulation collar 25 is in the low position P B of use. When the articulation collar 25 is in this position, the fixing system is rigidly held around the neck 4 and the bottle is ready to be used. In fact, in this configuration, the hoop 30 being located in the proximal position and therefore completely lowered, its inner wall 31 exerts radial pressure on the fixing means 15 which are in the engagement position. In other words, the fixing means 15 are engaged with the neck 4. In this case, the outer faces of the flexible tabs 15 are in vertical alignment with the flat portion 14, while their internal faces are completely engaged in the groove 7 of the cervix. It can be noted that the groove 7 comprises a recess 8. The recess 8 forms an anti-rotation system of the fixing system in which one or more lugs 15 can be housed.

En référence à la figure 3, le collet d'articulation 25 est dans la position haute PH de démontage. Lorsque le collet d'articulation 25 est précisément dans cette position, le système de fixation n'est plus en prise avec le col 4. Au besoin, l'utilisateur pourra éventuellement remplir de nouveau le réservoir 3 si le produit fluide utilisé se prête à une telle manipulation. Dans cette configuration, la frette 30 étant située à la position distale, et donc totalement remontée, la paroi intérieure 31 n'exerce plus de pression sur les moyens de fixation 15 ce qui libère lesdits moyens de fixation 15. En l'espèce, les pattes souples 15 sont en position de dégagement. Autrement dit les pattes souples 15 sont libres.With reference to the figure 3 , the articulation collar 25 is in the upper position P H for dismantling. When the articulation collar 25 is precisely in this position, the fixing system is no longer engaged with the neck 4. If necessary, the user may possibly refill the reservoir 3 if the fluid used is suitable for such manipulation. In this configuration, the hoop 30 being located in the distal position, and therefore completely raised, the inner wall 31 no longer exerts pressure on the fixing means 15 which releases said fixing means 15. In this case, the flexible tabs 15 are in the release position. In other words, the flexible tabs 15 are free.

Comme déjà indiqué, la figure 1 illustre le flacon avant fixation initiale de la tête de distribution 1 sur le réservoir. Une telle opération a lieu, par exemple, chez l'industriel en charge du remplissage initial du flacon.As already indicated, the figure 1 illustrates the bottle before initial attachment of the dispensing head 1 to the reservoir. Such an operation takes place, for example, at the manufacturer in charge of the initial filling of the bottle.

Dans cette configuration, le manchon 10 est monté sur le col 4, les pattes souples 15 étant libres. Le collet d'articulation 25 est en position basse PB d'utilisation. La frette 30 est dans une position escamotée correspondant à la position haute PH de démontage de la figure 3 mais sans que la frette soit déjà montée serrée sur ledit collet d'articulation 25, permettant de la sorte aux pattes souples 15 d'être libres et à la tête de distribution 1 d'être montée sur le réservoir.In this configuration, the sleeve 10 is mounted on the neck 4, the flexible tabs 15 being free. The articulation collar 25 is in the low position P B of use. The hoop 30 is in a retracted position corresponding to the high position P H for dismantling the figure 3 but without the hoop being already tightly mounted on said articulation collar 25, thereby allowing the flexible tabs 15 to be free and the dispensing head 1 to be mounted on the reservoir.

Une fois la tête de distribution 1 ainsi mise en place, la frette 30 est abaissée en force selon un mouvement de translation et la tête de distribution passe dans la configuration de la figure 2. Ce mouvement de translation est facilité par les nervures 32 dédiées au guidage du collet d'articulation 25.Once the dispensing head 1 thus installed, the hoop 30 is lowered in force in a translational movement and the dispensing head passes into the configuration of the figure 2 . This translational movement is facilitated by the ribs 32 dedicated to guiding the articulation collar 25.

En référence aux figures 2 et 3, la cinématique de déplacement du collet d'articulation 25 relativement au manchon 10 est décrite dans la suite.With reference to figures 2 and 3 , the kinematics of movement of the articulation collar 25 relative to the sleeve 10 is described below.

Passage du collet d'articulation 25 de la position haute PPassing the articulation collar 25 from the high position P HH de démontage vers la position basse Pdisassembly to the low position P BB d'utilisationof use

Préférentiellement, lorsque le collet d'articulation 25 est situé en position haute PH de démontage (fig. 3), il est en butée avec le manchon 10 au niveau d'une position de fin de course PF. Préférentiellement, également, lorsque le collet d'articulation 25 est situé en position basse PB d'utilisation (fig. 2), il est en butée avec ledit manchon 10 au niveau de la position de début de course PI. Comme cela a été mentionné au préalable, pour prévenir un démontage inopportun lors d'une utilisation du flacon, les dispositifs de l'art antérieur sont configurés pour que l'utilisateur soit obligé de dévisser le collet d'articulation 25 du manchon 10. Le remontage subséquent, s'il est permis, s'effectue alors par revissage.Preferably, when the articulation collar 25 is located in the high disassembly position P H ( fig. 3 ), it is in abutment with the sleeve 10 at an end position P F. Preferably, also, when the articulation collar 25 is located in the low position P B of use ( fig. 2 ), it is in abutment with said sleeve 10 at the start of travel position P I. As mentioned before, to prevent untimely disassembly when using the bottle, the devices of the prior art are configured so that the user is forced to unscrew the articulation collar 25 from the sleeve 10. The subsequent reassembly, if permitted, is then done by screwing it back in.

Alternativement, le collet d'articulation 25 et le manchon 10 peuvent être en butée, sans nécessairement que l'une desdites pièces soit encastrée dans l'autre pièce. En d'autres termes, il peut exister un jeu entre le collet d'articulation 25 et le manchon 10.Alternatively, the articulation collar 25 and the sleeve 10 can be in abutment, without necessarily that one of said parts is embedded in the other part. In other words, there may be a clearance between the articulation collar 25 and the sleeve 10.

Selon l'invention, les positions de début et de fin de course PI, PF sont situées de sorte que le collet d'articulation 25 soit apte à passer de la position haute PH de démontage (tel qu'illustré à la figure 2) vers la position basse PB d'utilisation (tel qu'illustré à la figure 3) par translation. Ainsi, quand bien même le démontage du système de fixation se fait, par exemple, par dévissage, ledit système de fixation peut être remonté sur le col 4 du réservoir 3 par simple mouvement de translation et donc un simple appui de l'utilisateur. Aucun vissage n'est donc nécessaire pour le remontage.According to the invention, the start and end positions P I , P F are located so that the articulation collar 25 is able to pass from the upper disassembly position P H (as illustrated in FIG. figure 2 ) towards the low position P B of use (as illustrated in the figure 3 ) by translation. Thus, even if the fixing system is dismantled, for example, by unscrewing, said fixing system can be reassembled on the neck 4 of the reservoir 3 by simple translational movement and therefore a simple support of the user. No screwing is therefore necessary for reassembly.

En référence à la figure 4b, le manchon 10 comprend avantageusement des premiers moyens de guidage, en translation, dudit collet d'articulation 25 de la position haute PH de démontage vers la position basse PB d'utilisation. Les premiers moyens de guidage en translation sont situés sur le collet de guidage 16. Ils s'étendent le long de la position de début de course PI et de la position de fin de course PF. Il est préférable que ces premiers moyens de guidage en translation soient au moins au nombre de deux. Cela permet de fiabiliser le déplacement du collet d'articulation 25 relativement au manchon 10.With reference to the figure 4b , the sleeve 10 advantageously comprises first means for guiding, in translation, said articulation collar 25 of the high position P H for dismantling towards the low position P B for use. The first translational guide means are located on the guide collar 16. They extend along the start of travel position P I and the end of travel position P F. It is preferable that these first means for guiding in translation are at least two in number. This makes the movement of the articulation collar 25 more reliable relative to the sleeve 10.

Avantageusement, ces premiers moyens de guidage en translation comprennent un logement de début de course 19 situé à la position de début de course PI et un logement de fin de course 20 situé à la position de fin de course PF. Les logements de début et de fin de course 19, 20 forment, en combinaison, une rainure ou encore une encoche ayant une emprise de forme sensiblement rectangulaire sur le collet de guidage 16. Comme illustré à la figure 4b, la rainure s'étend longitudinalement sur toute la hauteur du collet de guidage 16, c'est-à-dire entre un bord libre supérieur du collet de guidage 16 et la jupe 12. La hauteur du collet de guidage 16 correspond donc sensiblement à la distance longitudinale que peut parcourir le collet d'articulation 25 lors de sa course depuis la position haute PH de démontage vers la position basse PB d'utilisation. À ce propos, la jupe 12 forme une portée extérieure 13 sur laquelle vient s'appuyer une bordure inférieure du collet d'articulation 25 lorsqu'il est position basse PB d'utilisation. La portée extérieure 13 contribue au blocage en translation du collet d'articulation 25.Advantageously, these first means for guiding in translation comprise a start-of-travel housing 19 situated at the start-of-travel position P I and an end-of-travel housing 20 located at the end-of-travel position P F. The start and end of race housings 19, 20 form, in combination, a groove or else a notch having a grip of substantially rectangular shape on the guide collar 16. As illustrated in FIG. figure 4b , the groove extends longitudinally over the entire height of the guide collar 16, that is to say between an upper free edge of the guide collar 16 and the skirt 12. The height of the guide collar 16 therefore corresponds substantially to the longitudinal distance that the articulation collar 25 can travel during its travel from the high disassembly position P H to the low use position P B. In this regard, the skirt 12 forms an outer surface 13 on which rests a lower edge of the articulation collar 25 when it is in the low position P B of use. The outer surface 13 contributes to the locking in translation of the articulation collar 25.

Précisons également que le logement de fin de course 20 comprend une extrémité plane 20a formant une discontinuité au niveau du bord libre supérieur du collet de guidage 16. Cela permet notamment de prédisposer le collet d'articulation 25 par rapport au collet de guidage 16 et facilite le montage initial du collet d'articulation sur le manchon 10.It should also be noted that the end-of-travel housing 20 comprises a flat end 20a forming a discontinuity at the upper free edge of the guide collar 16. This makes it possible in particular to predispose the articulation collar 25 relative to the guide collar 16 and facilitates the initial mounting of the articulation collar on the sleeve 10.

Chacun desdits premiers moyens de guidage en translation comprend en outre un premier moyen de verrouillage 18. Les logements de début et de fin de course 19, 20 sont reliés par l'intermédiaire dudit premier moyen de verrouillage 18. Tout mouvement de translation du collet d'articulation 25 depuis la position haute PH de démontage vers la position basse PB d'utilisation implique que ledit collet d'articulation 25 soit en mesure de passer sur ledit premier moyen de verrouillage 18.Each of said first translation guide means further comprises a first locking means 18. The start and end of travel housings 19, 20 are connected by means of said first locking means 18. Any movement of translation of the collar d articulation 25 from the high disassembly position P H to the low position P B of use implies that said articulation collar 25 is able to pass over said first locking means 18.

Ledit premier moyen de verrouillage 18 est configuré pour autoriser le déplacement en translation dudit collet d'articulation 25 de la position haute PH de démontage vers la position basse PB d'utilisation par translation par application d'une pression seuil. Ainsi, la gestuelle de l'utilisateur reste simple puisqu'elle ne nécessite qu'un simple appui et, en même temps, le mouvement du collet d'articulation 25 de la position haute PH de démontage à la position basse PB d'utilisation ne peut pas résulter d'un appui involontaire, mais d'une volonté, de la part de l'utilisateur de fermer le flacon.Said first locking means 18 is configured to allow the displacement in translation of said articulation collar 25 from the high position P H for dismantling to the low position P B for use by translation by application of a threshold pressure. Thus, the gestures of the user remain simple since it requires only a simple press and, at the same time, the movement of the articulation collar 25 from the high disassembly position P H to the low position P B d ' use cannot result from an involuntary support, but from a will on the part of the user to close the bottle.

De manière avantageuse, ledit premier moyen de verrouillage 18 forme un bossage, c'est-à-dire une surépaisseur entre lesdits logements de début et de fin de course 19, 20.Advantageously, said first locking means 18 forms a boss, that is to say an additional thickness between said start and end of race housings 19, 20.

Préférentiellement, le premier moyen de verrouillage 18 comprend une portion de retenue 18a. Ladite portion de retenue 18a forme une portée pour le collet d'articulation 25 lorsque ce dernier est en position haute PH de démontage. La portion de retenue 18a est inclinée par rapport à un fond de la rainure. Plus précisément, elle fait un angle obtus avec le logement de fin de course 20. En étant ainsi configurée, la portion de retenue 18a permet aussi bien le maintien du collet d'articulation 25 que son glissement le long de la rainure, et donc depuis la position de fin de course PF vers la position de début de course PI.Preferably, the first locking means 18 comprises a retaining portion 18a. Said retaining portion 18a forms a bearing surface for the articulation collar 25 when the latter is in the high position P H for dismantling. The retaining portion 18a is inclined relative to a bottom of the groove. More precisely, it forms an obtuse angle with the end-of-travel housing 20. By being thus configured, the retaining portion 18a makes it possible both to maintain the articulation collar 25 and to slide it along the groove, and therefore from the end position P F towards the start position P I.

En outre, ledit premier moyen de verrouillage 18 comprend un rebord de verrouillage 18b. Ce rebord de verrouillage 18b s'étend depuis le fond de la rainure selon un plan transversal à la direction d'axe X. Plus précisément, il fait un angle droit avec le logement de début de course 19. Ainsi, une fois que le collet d'articulation 25 a atteint la position basse PB d'utilisation, il ne peut pas revenir à la position haute PB de démontage par translation le long de la rainure. Le rebord de verrouillage 18b forme donc une butée supérieure pour ledit collet d'articulation 25 en position basse PB d'utilisation.In addition, said first locking means 18 comprises a locking rim 18b. This locking rim 18b extends from the bottom of the groove in a plane transverse to the direction of axis X. More specifically, it makes a right angle with the start of race housing 19. Thus, once the collar 25 has reached the low position P B for use, it cannot return to the high position P B for disassembly by translation along the groove. The locking flange 18b therefore forms an upper stop for said articulation collar 25 in the low position P B of use.

Le premier moyen de verrouillage 18 comprend une arête 18c par laquelle la portion de retenue 18a est reliée au rebord de verrouillage 18b. L'arête 18c peut être assimilée à un sommet du bossage 18. Dans le mode de réalisation de la figure 4b, l'arête 18c présente une hauteur, dite hauteur de saillie sensiblement égale à la profondeur de la rainure par rapport à un pourtour extérieur du collet de guidage 16. Ceci n'est pas obligatoire. La hauteur de saillie définit la pression qui doit être appliquée au collet d'articulation 25 pour franchir le premier moyen de verrouillage 18 et atteindre le logement de début de course 19. On comprend bien que plus la hauteur de saillie est élevée plus la pression à exercer est importante.The first locking means 18 comprises an edge 18c by which the retaining portion 18a is connected to the locking rim 18b. The edge 18c can be likened to a vertex of the boss 18. In the embodiment of the figure 4b , the edge 18c has a height, called the projection height substantially equal to the depth of the groove relative to an outer periphery of the guide collar 16. This is not compulsory. The projection height defines the pressure which must be applied to the articulation collar 25 to pass through the first locking means 18 and reach the start of race housing 19. It will be understood that the higher the projection height, the more the pressure at exercise is important.

Ainsi, lorsque le collet d'articulation 25 glisse, depuis le logement de fin de course 20 vers le logement de début de course 19, il passe successivement, sur la portion de retenue 18a et l'arête 18c.Thus, when the articulation collar 25 slides, from the end-of-travel housing 20 towards the start-of-travel housing 19, it passes successively over the retaining portion 18a and the edge 18c.

En référence à la figure 4c, le collet d'articulation 25 se présente sous la forme d'un cylindre creux. Ceci n'est pas limitatif dans le cadre de la présente invention. En tout état de cause, il est nécessaire que la forme du collet d'articulation 25 soit conforme à celle du manchon 10 puisque le collet d'articulation 25 est monté mobile autour dudit manchon 10. Le collet d'articulation 25 comprend une protubérance 26 apte à se déplacer le long desdits premiers moyens de guidage en translation. La protubérance 26 s'étend radialement depuis une paroi interne du collet d'articulation 25. Elle présente une forme généralement rectangulaire, bien que ce ne soit pas obligatoire. Cette forme est adaptée à celle des moyens de guidage le long desquels elle doit se déplacer. Plus précisément, des côtés latéraux, orientés longitudinalement de la protubérance 26 glissent contre des côtés latéraux, orientés longitudinalement de la rainure formée par les logements 19, 20.With reference to the figure 4c , the articulation collar 25 is in the form of a hollow cylinder. This is not limiting in the context of the present invention. In any event, it is necessary that the shape of the articulation collar 25 conforms to that of the sleeve 10 since the articulation collar 25 is mounted movable around said sleeve 10. The articulation collar 25 comprises a protuberance 26 able to move along said first guide means in translation. The protrusion 26 extends radially from an internal wall of the articulation collar 25. It has a generally rectangular shape, although this is not compulsory. This shape is adapted to that of the guide means along which it must move. More precisely, lateral sides, oriented longitudinally of the protuberance 26 slide against lateral sides, oriented longitudinally of the groove formed by the housings 19, 20.

Le collet extérieur 25 présente en outre un jonc intérieur 27 apte à venir en appui sur une surépaisseur 17 d'une bordure supérieure du manchon 10. Ainsi, lorsque le collet d'articulation 25 est en position haute PH de démontage, il est configuré pour rester au niveau de la position de fin de course 20, de sorte que le collet d'articulation 25 est maintenu au niveau du manchon 10. Lorsque le collet d'articulation 25 est en position basse PB d'utilisation, une bordure inférieure dudit collet d'articulation est apte à venir en appui sur la portée extérieure 13.The external collar 25 also has an internal ring 27 capable of coming to bear on an additional thickness 17 of an upper edge of the sleeve 10. Thus, when the articulation collar 25 is in the high position P H for dismantling, it is configured to remain at the end position 20, so that the articulation collar 25 is maintained at the sleeve 10. When the articulation collar 25 is in the low position P B of use, a lower border of said articulation collar is capable of coming to bear on the outer surface 13.

En référence à la figure 4b, le manchon 10 peut comprendre, en plus des premiers moyens de guidage en translation, des seconds moyens de guidage du collet d'articulation 25. Ces seconds moyens de guidage permettent au collet d'articulation 25 d'être vissé et dévissé dudit manchon 10.With reference to the figure 4b , the sleeve 10 may comprise, in addition to the first means for guiding in translation, second means for guiding the hinge collar 25. These second guide means allow the hinge collar 25 to be screwed and unscrewed from said sleeve 10.

De manière similaire aux premiers moyens de guidage en translation, ces seconds moyens de guidage sont positionnés sur le collet de guidage 16. Préférentiellement, ils s'étendent entre lesdites positions de début et de fin de course PI, PF. Chacun comporte à ses extrémités un logement de début de course 19 et un logement de fin de course 20. Il faut comprendre que s'il y a deux seconds moyens de guidage cela implique qu'il y a quatre logements au total puisque chacun des seconds moyens de guidage comprend un logement de début de course 19 et un logement de fin de course 20, dans la suite longitudinal l'un de l'autre, deux à deux.Similarly to the first translation guide means, these second guide means are positioned on the guide collar 16. Preferably, they extend between said start and end of travel positions P I , P F. Each has at its ends a start of race housing 19 and a end of race housing 20. It should be understood that if there are two second guide means this implies that there are four housings in total since each of the second guide means comprises a start-of-travel housing 19 and an end-of-travel housing 20, in the longitudinal sequence of one another, two by two.

Le système de fixation selon l'invention est particulièrement ingénieux. En effet, les logements de début et de fin de course 19, 20 dont il est question dans les seconds moyens de guidage sont les mêmes logements qui forment les premiers moyens de guidage en translation, en l'espèce la rainure. L'architecture des moyens de guidage est ainsi optimisée pour permettre à la fois le remontage du système de fixation par appui simple de l'utilisateur mais également le vissage et le dévissage dudit système. En référence à l'exemple cité ci-dessus, on comprend bien que s'il y a quatre logements au total il y a donc deux premiers moyens de guidage en translation, chacun étant formé d'un logement de début de course 19 et d'un logement de fin de course 20. Cela dit, dans cette configuration, comme cela sera mieux compris dans la suite le logement de fin de course 20 d'un second moyen de guidage ne forme pas de rainure avec le logement de début de course 19 du même second moyen de guidage.The fixing system according to the invention is particularly ingenious. Indeed, the start and end of race housings 19, 20 which are discussed in the second guide means are the same housings which form the first guide means in translation, in this case the groove. The architecture of the guide means is thus optimized to allow both reassembly of the fastening system by simple pressing of the user but also the screwing and unscrewing of said system. With reference to the example cited above, it is clear that if there are four housings in total, there are therefore two first means for guiding in translation, each being formed by a race start housing 19 and d an end-of-travel housing 20. That said, in this configuration, as will be better understood hereinafter, the end-of-travel housing 20 of a second guide means does not form a groove with the start-of-travel housing 19 of the same second guide means.

Les seconds moyens de guidage sont configurés pour que le collet d'articulation 25 soit apte à effectuer un mouvement de rotation et de translation, notamment, de vissage autour dudit manchon 10 en vue de procéder au démontage du système de fixation.The second guide means are configured so that the articulation collar 25 is capable of carrying out a rotation and translation movement, in particular, of screwing around said sleeve 10 in order to disassemble the fixing system.

À cet égard, chacun des seconds moyens de guidage comprend avantageusement un tronçon hélicoïdal 21. Chaque tronçon hélicoïdal 21 comprend une première extrémité 22 comportant le logement de début de course 19 et une deuxième extrémité 23 comportant le logement de fin de course 20. Le nombre de seconds moyens de guidage est de préférence au moins égal à deux. Cela dit, ce nombre n'est pas limitatif.In this regard, each of the second guide means advantageously comprises a helical section 21. Each helical section 21 comprises a first end 22 comprising the start-of-travel housing 19 and a second end 23 comprising the end-of-travel housing 20. The number of second guide means is preferably at least equal to two. However, this number is not limiting.

Considérons que le manchon 10 comprend n, n étant un entier naturel, seconds moyens de guidage comprenant chacun un tronçon hélicoïdal 211, ...,21i, 21i+i,..., 21n, i étant un entier naturel avec i≥1 et i+1≤n. Chacun des tronçons hélicoïdaux 211, ....,21i, 21i+i,..., 21n, i étant un entier naturel avec i<n, comprend respectivement une première extrémité 221, ...,22i, 22i+1,..., 22n et une deuxième extrémité 231, ...,23i, 23i+1,..., 23n. Lesdits seconds moyens de guidage sont configurés de sorte que la première extrémité 221 d'un premier tronçon hélicoïdal 211 est située en vis-à-vis de la deuxième extrémité 23n d'un dernier tronçon hélicoïdal 21n et que chacune des autres premières extrémités 22i+1 des tronçons hélicoïdaux est située en vis-à-vis des autres deuxièmes extrémités 23i des tronçons hélicoïdaux qui les précèdent. En fait, les premières extrémités 221, ...,22i, 22i+1,..., 22n forment avec les deuxièmes extrémités 231, ...,23i, 23i+1,..., 23n les logements des premiers moyens de guidage en translation, en l'espèce des rainures, ce qui fait du système de fixation de l'invention un système à la fois pratique et ingénieux.Let us consider that the sleeve 10 comprises n, n being a natural number, second guide means each comprising a helical section 21 1 , ..., 21 i , 21 i + i , ..., 21 n , i being a natural number with i≥1 and i + 1≤n. Each of the helical sections 21 1 , ...., 21 i , 21 i + i , ..., 21 n , i being a natural integer with i <n, respectively comprises a first end 22 1 , ..., 22 i , 22 i + 1 , ..., 22 n and a second end 23 1 , ..., 23 i , 23 i + 1 , ..., 23 n . Said second guide means are configured so that the first end 22 1 of a first helical section 21 1 is located opposite the second end 23 n of a last helical section 21 n and that each of the others first ends 22 i + 1 of the helical sections is located opposite the other second ends 23 i of the helical sections which precede them. In fact, the first ends 22 1 , ..., 22 i , 22 i + 1 , ..., 22 n form with the second ends 23 1 , ..., 23 i , 23 i + 1 , ... , 23 n the housings of the first translational guide means, in this case grooves, which makes the fixing system of the invention a system that is both practical and ingenious.

Dans le cas particulier où n est égal à un, cela signifie qu'il y a un unique moyen de guidage comportant un tronçon hélicoïdal 21. Dans ce cas, on comprend que les extrémités du tronçon hélicoïdal 21 forment aussi les logements de début et de fin de course 19, 20 de la rainure permettant au collet d'articulation 25 de passer de la position haute PH de démontage à la position basse PB d'utilisation.In the particular case where n is equal to one, this means that there is a single guide means comprising a helical section 21. In this case, it is understood that the ends of the helical section 21 also form the start and end housings. limit switch 19, 20 of the groove allowing the articulation collar 25 to pass from the high position P H for dismantling to the low position P B for use.

Dans le cas particulier où n est égal à deux, cela signifie que le premier tronçon hélicoïdal 211 fait un demi-tour du collet de guidage 16 et le deuxième tronçon hélicoïdal 212 fait un demi-tour restant du collet de guidage 16. Dans cette configuration, la première extrémité 221 du premier tronçon hélicoïdal 211 est située en vis-à-vis de la deuxième extrémité 232 du deuxième tronçon hélicoïdal 212 et la première extrémité 222 du deuxième tronçon hélicoïdal 225 est située en vis-à-vis de la deuxième extrémité 231 du premier tronçon hélicoïdal. La première extrémité 221 et la deuxième extrémité 232 forment les logements d'un premier moyen de guidage en translation, tandis que la première extrémité 222 et la deuxième extrémité 231 forment les logements d'un deuxième moyen de guidage en translation.In the particular case where n is equal to two, this means that the first helical section 21 1 makes a U-turn of the guide collar 16 and the second helical section 21 2 makes a remaining U-turn of the guide collar 16. In this configuration, the first end 22 1 of the first helical section 21 1 is located opposite the second end 23 2 of the second helical section 21 2 and the first end 22 2 of the second helical section 22 5 is located opposite -with respect to the second end 23 1 of the first helical section. The first end 22 1 and the second end 23 2 form the housings of a first translational guide means, while the first end 22 2 and the second end 23 1 form the housings of a second translational guide means.

Préférentiellement, chaque second moyen de guidage comprend des deuxièmes moyens de verrouillage 19b, 20b séparant les logements de début et de fin de course 19, 20 dudit tronçon hélicoïdal 21. Lesdits deuxièmes moyens de verrouillage 19b, 20b consistent en des bossages ou surépaisseurs dont une hauteur de saillie détermine la pression qui doit être appliquée pour que le collet d'articulation 25, en particulier la protubérance 26 quitte le logement de début ou de fin de course 19, 20 pour atteindre le tronçon hélicoïdal 21. En d'autres termes, les deuxièmes moyens de verrouillage 19b, 20b sont configurés pour autoriser le mouvement de rotation du collet d'articulation 25 autour dudit manchon 10 par application d'une pression seuil.Preferably, each second guide means comprises second locking means 19b, 20b separating the start and end of race housings 19, 20 of said helical section 21. Said second locking means 19b, 20b consist of bosses or extra thicknesses, one of which projection height determines the pressure which must be applied in order for the articulation collar 25, in particular the protuberance 26 to leave the start or end of race housing 19, 20 to reach the helical section 21. In other words, the second locking means 19b, 20b are configured to allow the rotational movement of the articulation collar 25 around said sleeve 10 by application of a threshold pressure.

Dans un mode de réalisation préféré, la surépaisseur 20b forme une butée franche (tel qu'illustré sur la figure 4b). En d'autres termes, elle empêche le vissage du collet d'articulation 25 autour du manchon 10, quand bien même une pression élevée serait exercée. Dans une telle configuration la protubérance 26 ne peut pas quitter le logement de fin de course 20 pour atteindre le tronçon hélicoïdal 21. On comprend ainsi que seule la translation de la protubérance 26 depuis le logement de fin de course 20 vers le logement de début de course 19 est autorisé pour atteindre la position basse PB d'utilisation.In a preferred embodiment, the additional thickness 20b forms a frank stop (as illustrated on the figure 4b ). In other words, it prevents the articulation collar 25 from being screwed around the sleeve 10, even if high pressure is exerted. In such a configuration, the protuberance 26 cannot leave the end-of-travel housing 20 to reach the helical section 21. It is thus understood that only the translation of the protuberance 26 from the end-of-travel housing 20 towards the start housing of stroke 19 is authorized to reach the low position P B of use.

Dans un mode de réalisation préféré, la surépaisseur 20b est configurée de sorte que le dévissage du collet d'articulation 25 autour du manchon 10 soit autorisé par application d'une pression seuil (tel qu'illustré sur la figure 4b).In a preferred embodiment, the additional thickness 20b is configured so that the unscrewing of the articulation collar 25 around the sleeve 10 is authorized by application of a threshold pressure (as illustrated on the figure 4b ).

On comprend bien que lorsque la protubérance 26 se déplace depuis le logement de début de course 19 vers le logement de fin de course 20 en passant sur la surépaisseur 19b, le long du tronçon hélicoïdal 21 et sur la surépaisseur 20b, dans cet ordre il s'agit d'un dévissage. Le collet d'articulation 25 passe donc de la position basse PB d'utilisation à la position haute PH de démontage par dévissage. Pour rappel, c'est la seule alternative possible puisqu'il n'est pas possible de démonter le système de fixation par translation, notamment à cause de la butée 18b. Alternativement, lorsque la protubérance 26 se déplace depuis le logement de fin de course 20 vers le logement de début de course 19 en passant sur la surépaisseur 20b, le long du tronçon hélicoïdal 21 et sur la surépaisseur 19b, dans cet ordre il s'agit d'un vissage. Le collet d'articulation 25 passe donc de la position haute PH de démontage à la position basse d'utilisation PB par vissage. Ceci n'est pas obligatoire dans la présente invention puisque les premiers moyens de guidage en translation permettent de passer de la position haute PH de démontage à la position basse d'utilisation PB par translation du collet d'articulation 25.It will be understood that when the protuberance 26 moves from the start-of-travel housing 19 to the end-of-travel housing 20 passing over the additional thickness 19b, along the helical section 21 and over the additional thickness 20b, in this order it s 'is an unscrewing. The articulation collar 25 therefore passes from the low position P B for use to the high position P H for dismantling by unscrewing. As a reminder, this is the only possible alternative since it is not possible to disassemble the fastening system by translation, in particular because of the stop 18b. Alternatively, when the protrusion 26 moves from the end-of-travel housing 20 to the start-of-travel housing 19 passing over the additional thickness 20b, along the helical section 21 and over the additional thickness 19b, in this order it is a matter of of a screwing. The articulation collar 25 therefore passes from the high position P H for dismantling to the low position for use P B by screwing. This is not compulsory in the present invention since the first means for guiding in translation make it possible to pass from the high position P H for dismantling to the low position for use P B by translation of the articulation collar 25.

Autrement dit, bien que le remontage du système de fixation selon l'invention soit possible par simple translation du collet d'articulation 25 depuis la position haute PH de démontage vers la position basse PB d'utilisation, il est également possible de monter le système de fixation par vissage. Ceci lui confère une grande souplesse d'utilisation.In other words, although the reassembly of the fixing system according to the invention is possible by simple translation of the articulation collar 25 from the high position P H for dismantling to the low position P B for use, it is also possible to mount the screw fixing system. This gives it great flexibility of use.
