Description

L'invention concerne un système de fixation d'une pompe de distribution sur le col d'un flacon contenant un produit fluide, ainsi qu'un flacon de distribution d'un produit fluide comprenant une pompe fixée au moyen d'un tel système.The invention relates to a system for attaching a dispensing pump to the neck of a bottle containing a fluid product, as well as a dispensing bottle for a fluid product comprising a pump attached by means of such a system.

En particulier, le flacon 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 bottle allows the packaging and distribution of a liquid or a cream, for example a perfume, for a cosmetic or pharmaceutical application.

On connaît de tels flacons comprenant un corps définissant un réservoir de conditionnement du produit, un col surmontant ledit corps en 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 bottles are known comprising a body defining a container for packaging the product, a neck surmounting said body by defining an upper opening for said reservoir, and a pump mounted in said upper opening by arranging the means for supplying said pump to it. 'inside said tank. 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 un collet portant des moyens de solidarisation de la pompe et une jupe inférieure pourvue de moyens de fixation dudit manchon sur ledit flacon.To ensure the positioning and fixing of the pump relative to the body, it is possible to use a system comprising a sleeve having a collar carrying means for securing the pump and a lower skirt provided with means for fixing said sleeve on said bottle.

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

En particulier, le document US-4 773 553 enseigne l'utilisation d'une jupe pourvue de griffes qui présente une configuration ouverte pour permettre son positionnement autour du col, lesdites griffes étant rabattues et maintenues en position sous le col lors du coulissement de la frette vers sa position basse.In particular, the document US-4,773,553 teaches the use of a skirt provided with claws which has an open configuration to allow its positioning around the neck, said claws being folded down and held in position under the neck during the sliding of the hoop towards its low position.

La frette, notamment réalisée en matériau rigide, forme ainsi outil de rabattement des griffes et permet d'assurer le maintien dans le temps des griffes en position rabattue, notamment relativement aux variations de température. En outre, elle peut procurer un effet esthétique en formant enjoliveur de masquage du col, de la zone de jonction entre le corps et le col (dite épaules du corps), ainsi qu'éventuellement de la partie inférieure de la pompe.The hoop, in particular made of a rigid material, thus forms a tool for folding back the claws and makes it possible to ensure that the claws in the folded position, especially in relation to temperature variations. In addition, it can provide an aesthetic effect by forming a cover for masking the neck, the junction zone between the body and the neck (called the shoulders of the body), as well as possibly the lower part of the pump.

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 corps 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 cannot be removed. 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 plastic and metal, from the body often made in a different plastic category or in glass. .

Pour résoudre ce problème, on connaît l'utilisation de manchons qui sont vissables sur le col. 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, it is known to use sleeves which can be screwed onto the 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. Furthermore, 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.

Le document WO2006/129043 divulgue un manchon vissable, avec un filetage en saillie qui vient mordre la matière d'une bague de fixation et provoquer une déformation irréversible de la matière lors du montage. Cette fixation est définitive, et le manchon n'est pas destiné à être dévissé. Le document WO2006/129043 montre un système de fixation d'un pompe de distribution sur le col d'un flacon contenant un produit fluide selon le préambule de la revendication 1.The document WO2006 / 129043 discloses a screwable sleeve, with a projecting thread which bites the material of a fixing ring and causes irreversible deformation of the material during assembly. This fixing is final, and the sleeve is not intended to be unscrewed. The document WO2006 / 129043 shows a system for attaching a dispensing pump to the neck of a bottle containing a fluid product according to the preamble of claim 1.

L'invention vise à perfectionner l'art antérieur en proposant notamment un système de fixation d'une pompe sur le col d'un flacon qui permet leur séparation quasi irréversible à fin de recyclage, et ce en présentant une esthétique avantageuse et une simplicité de fixation.The invention aims to improve the prior art by proposing in particular a system for fixing a pump on the neck of a bottle which allows their almost irreversible separation at the end of recycling, and this by presenting an advantageous aesthetic and ease of fixing.

Dans la description, les termes de positionnement dans l'espace sont pris en référence à la position du système de fixation représenté sur les figures.In the description, the terms of positioning in space are taken with reference to the position of the fixing system shown in the figures.

En relation avec les figures, on décrit ci-dessous un flacon 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 bottle intended to contain a fluid product with a view to its distribution is described below. In particular examples, the product can be a liquid or a cream, for example a perfume, for cosmetic or pharmaceutical application.

Le flacon comprend un corps 1 qui peut être formé en matériau rigide, notamment en verre ou en matériau plastique, pour définir un réservoir de conditionnement du produit. Le corps 1 est surmonté par un col 2 formé d'une seule pièce avec ledit corps en définissant une ouverture supérieure pour le réservoir. Selon une réalisation, le col 2 est de type à carnette tel que normalisé par la norme FEA en Europe, sans que l'invention ne soit limitée à un tel type de col.The bottle comprises a body 1 which may be formed from a rigid material, in particular from glass or from a plastic material, to define a reservoir of product packaging. The body 1 is surmounted by a neck 2 formed integrally with said body, defining an upper opening for the reservoir. According to one embodiment, the neck 2 is of the carnette type as standardized by the FEA standard in Europe, without the invention being limited to such a type of neck.

Le flacon de distribution comprend également une pompe 3 montée dans l'ouverture supérieure en disposant les moyens d'alimentation de ladite pompe à l'intérieur du réservoir. La pompe représentée comprend un corps dont la périphérie est montée sans serrage dans l'ouverture.The dispensing bottle also comprises a pump 3 mounted in the upper opening by placing the supply means of said pump inside the reservoir. The pump shown comprises a body whose periphery is mounted loosely in the opening.

Le corps de la pompe 3 présente une partie inférieure qui est pourvue d'un orifice d'alimentation, les moyens d'alimentation comprenant un tube plongeur 4 présentant une partie supérieure fixée dans l'orifice et une partie inférieure disposée contre le fond du réservoir.The body of the pump 3 has a lower part which is provided with a supply orifice, the supply means comprising a dip tube 4 having an upper part fixed in the orifice and a lower part disposed against the bottom of the reservoir. .

Par ailleurs, la pompe comprend un bouton poussoir 5 équipé d'un orifice de distribution 6. Selon une réalisation connue, le bouton 5 actionne en translation réversible un gicleur sur une course de distribution et un piston est également monté sur le gicleur entre un état d'obturation et un état d'alimentation des orifices dudit gicleur. Toutefois, l'invention n'est pas limitée à un mode de réalisation particulier de la pompe 3.Furthermore, the pump comprises a push button 5 equipped with a dispensing orifice 6. According to a known embodiment, the button 5 actuates a nozzle in reversible translation on a dispensing stroke and a piston is also mounted on the nozzle between a state. sealing and a supply state of the orifices of said nozzle. However, the invention is not limited to a particular embodiment of the pump 3.

Le flacon peut également être pourvu d'un capot de protection de la pompe entre deux utilisations. En variante, la pompe peut être verrouillable, notamment par rotation du bouton poussoir entre une position de distribution et une position dans laquelle l'appui sur le bouton poussoir est bloqué.The bottle can also be provided with a protective cover for the pump between two uses. As a variant, the pump can be lockable, in particular by rotating the push button between a dispensing position and a position in which the pressing of the push button is blocked.

Pour assurer le positionnement et la fixation de la pompe 3 sur le col 2, le flacon comprend en outre un système de fixation comprenant un manchon 7 qui peut être réalisé de façon monobloc en matériau ductile, notamment en matière plastique de type polyoléfine.To ensure the positioning and fixing of the pump 3 on the neck 2, the bottle further comprises a fixing system comprising a sleeve 7 which can be made in one piece from ductile material, in particular from polyolefin type plastic.

En partie supérieure, le manchon 7 présente un collet intérieur 8 qui porte des moyens de solidarisation de la pompe 3. Dans le mode de réalisation représenté, une armature d'association de la pompe 3 est formée dans le collet intérieur 8 afin de rendre ladite pompe solidaire du manchon 7. En variante non représentée, le manchon 7 peut être intégré au corps de la pompe 3, par exemple en formant extenseur pour ladite pompe, les moyens de solidarisation étant alors permanents.In the upper part, the sleeve 7 has an internal collar 8 which carries means for securing the pump 3. In the embodiment shown, an association frame for the pump 3 is formed in the internal collar 8 in order to make said pump integral with the sleeve 7. In a variant not shown, the sleeve 7 can be integrated into the body of the pump 3, for example by forming an expander for said pump, the securing means then being permanent.

En particulier, l'armature d'association comprend un orifice 9 dans lequel la pompe 3 est montée avec le bouton poussoir 5 disposé au-dessus du manchon 7, ladite armature comprenant en outre une gorge d'encliquetage 10 d'un bourrelet 11 formé sur le corps de la pompe 3.In particular, the association frame comprises an orifice 9 in which the pump 3 is mounted with the push button 5 disposed above the sleeve 7, said frame further comprising a snap-fit groove 10 of a bead 11 formed on the pump body 3.

Le manchon 7 présente également une jupe inférieure 12 qui s'étend axialement d'une pièce sous le collet intérieur 8, ladite jupe étant pourvue de moyens de fixation dudit manchon sur le flacon. En particulier, la jupe 12 peut être déformable entre une configuration de montage dans laquelle ladite jupe est positionnable autour du col 2 et une configuration de serrage de ladite jupe autour dudit col pour assurer la fixation. Pour ce faire, la jupe 12 peut former une enveloppe intérieure de géométrie respectivement conique pour le positionnement et cylindrique pour la fixation.The sleeve 7 also has a lower skirt 12 which extends axially in one piece under the internal collar 8, said skirt being provided with means for fixing said sleeve to the bottle. In particular, the skirt 12 can be deformable between a mounting configuration in which said skirt can be positioned around the neck 2 and a tightening configuration of said skirt around said neck to ensure the fixing. To do this, the skirt 12 can form an inner envelope of respectively conical geometry for positioning and cylindrical for fixing.

Dans le mode de réalisation représentée, la jupe 12 présente une couronne supérieure 13 sous laquelle s'étendent des griffes 14 formant moyens de fixation. Par ailleurs, la couronne 13 est reliée à l'extrémité inférieure du collet intérieur 8 par l'intermédiaire d'un épaulement rentrant 15.In the embodiment shown, the skirt 12 has an upper ring 13 under which the claws 14 extend, forming fixing means. Furthermore, the crown 13 is connected to the lower end of the internal collar 8 by means of a re-entrant shoulder 15.

Le système de fixation comprend également une frette 16 réalisée en une pièce, notamment en matériau rigide tel qu'un métal et par exemple en aluminium. La frette 16 est montée en coulissement autour de la jupe 12 entre une position haute dans laquelle les moyens de fixation sont libres de sorte à permettre le positionnement de ladite jupe autour du col 2 et une position basse dans laquelle les moyens de fixation sont contraints par ladite frette pour assurer la fixation étanche du manchon 7 sur ledit col.The fixing system also comprises a hoop 16 made in one piece, in particular in a rigid material such as a metal and for example in aluminum. The band 16 is mounted to slide around the skirt 12 between a high position in which the fixing means are free so as to allow the positioning of said skirt around the neck 2 and a low position wherein the fixing means are constrained by said hoop to ensure the sealed fixing of the sleeve 7 on said neck.

Ainsi, la fixation de la pompe 3 sur le flacon est réalisée en solidarisant ladite pompe au collet intérieur 8, les moyens de fixation de la jupe 12 étant contraints par la frette 16 en position basse pour assurer la fixation étanche du manchon 7 sur le col 2.Thus, the fixing of the pump 3 on the bottle is carried out by securing said pump to the internal collar 8, the fixing means of the skirt 12 being constrained by the hoop 16 in the low position to ensure the sealed fixing of the sleeve 7 on the neck. 2.

Dans le mode de réalisation représenté, le diamètre intérieur de la frette 16 est agencé pour permettre un glissement de ladite frette sur la couronne 13, les griffes 14 à l'état libre étant disposées en relief par rapport à ladite couronne (figures 1, 7). La frette 16 en position haute est montée autour de la couronne 13 et, en position basse, le coulissement de la frette 16 autour des griffes 14 contraint leur rabattement puis leur maintien radial sous le col 2 (figure 5).In the embodiment shown, the internal diameter of the hoop 16 is arranged to allow sliding of said hoop on the crown 13, the claws 14 in the free state being arranged in relief relative to said crown ( figures 1 , 7 ). The hoop 16 in the high position is mounted around the crown 13 and, in the low position, the sliding of the hoop 16 around the claws 14 forces their folding then their radial retention under the neck 2 ( figure 5 ).

En variante non représentée, les griffes 14 à l'état libre peuvent être disposées sensiblement dans le prolongement axial de la couronne 13, la frette 16 en position basse assurant alors le maintien radial desdites griffes pour assurer la fixation étanche du manchon 7 sur le col 2.In a variant not shown, the claws 14 in the free state can be arranged substantially in the axial extension of the crown 13, the hoop 16 in the low position then ensuring the radial retention of said claws to ensure the tight fixing of the sleeve 7 on the neck 2.

Le système de fixation comprend en outre un collet extérieur 17 qui est monté autour du collet intérieur 8 par l'intermédiaire d'un dispositif de déplacement dudit collet extérieur entre une position basse d'utilisation et une position haute de démontage. En particulier, le collet extérieur 17 est monté au dessus de l'épaulement rentrant 15 en présentant une épaisseur sensiblement égale à la longueur dudit épaulement de sorte que l'extérieur dudit collet soit sensiblement dans le prolongement axial de l'extérieur de la couronne 13.The fixing system further comprises an outer collar 17 which is mounted around the inner collar 8 by means of a device for moving said outer collar between a low position of use and a high position for removal. In particular, the outer collar 17 is mounted above the re-entrant shoulder 15 having a thickness substantially equal to the length of said shoulder so that the outside of said collar is substantially in the axial extension of the outside of the crown 13 .

Par ailleurs, la frette 16 en position basse est solidarisée au collet extérieur 17 pour actionner le déplacement dudit collet vers sa position haute en entraînant ladite frette relativement à la jupe 12 sur une course suffisante pour libérer les moyens de fixation (figure 7). En particulier, la course peut correspondre à celle relative au passage de la frette 16 depuis sa position haute vers sa position basse, le collet extérieur 17 en position haute permettant alors de disposer la frette 16 en position haute.Furthermore, the hoop 16 in the low position is secured to the outer collar 17 to actuate the movement of said collar towards its high position by driving said hoop relative to the skirt 12 over a sufficient stroke to release the fixing means ( figure 7 ). In particular, the stroke may correspond to that relating to the passage of the hoop 16 from its high position to its position. low, the outer collar 17 in the high position then allowing the band 16 to be placed in the high position.

Ainsi, après fixation de la pompe 3 (figure 5), il est possible de démonter l'ensemble système de fixation - pompe 3 en exerçant un effort adapté sur la frette 16 de sorte à actionner le déplacement relativement à la jupe 12 de l'ensemble collet extérieur 17 - frette 16. Ainsi, on peut satisfaire de façon simple aux contraintes de recyclabilité des composants du flacon.Thus, after fixing the pump 3 ( figure 5 ), it is possible to remove the entire fixing system - pump 3 by exerting a suitable force on the hoop 16 so as to actuate the movement relative to the skirt 12 of the outer collar 17 - hoop 16 assembly. can easily meet the recyclability constraints of the components of the bottle.

Le dispositif de déplacement peut être au moins partiellement actionné en rotation par la frette 16. Ainsi, le démontage est réalisé par un mouvement intuitif de dévissage, notamment dans le sens antihoraire, par l'intermédiaire de la frette 16. Cette réalisation combine donc les avantages d'une fixation au moyen d'un manchon déformable 7 avec la possibilité de dévisser ledit manchon, et ce sans les inconvénients de chacune de ces réalisations.The displacement device can be at least partially actuated in rotation by the hoop 16. Thus, the disassembly is carried out by an intuitive unscrewing movement, in particular in the counterclockwise direction, by means of the hoop 16. This embodiment therefore combines the advantages of fixing by means of a deformable sleeve 7 with the possibility of unscrewing said sleeve, and this without the drawbacks of each of these embodiments.

En particulier, le système de fixation permet de prévoir une frette 16 qui, en position basse, vient en appui sans jeu contre les épaules du corps 1 (figure 5) de sorte à parfaire l'esthétique du flacon. En outre, les flacons sont particulièrement simples à installer sur les lignes de remplissage puisque le montage de la pompe 3 ne nécessite pas de vissage.In particular, the fixing system makes it possible to provide a hoop 16 which, in the low position, bears without play against the shoulders of the body 1 ( figure 5 ) so as to perfect the aesthetics of the bottle. In addition, the bottles are particularly easy to install on the filling lines since the assembly of the pump 3 does not require screwing.

Selon la réalisation représentée, le démontage est réalisé par une cinématique de type baïonnette comprenant une rotation suivie d'une translation de l'ensemble collet extérieur 17 - frette 16 par rapport à la jupe 12. En variante, une rotation seule peut être prévue, le dispositif de déplacement étant alors agencé pour transformer un effort de rotation sur la frette 16 en un mouvement de translation de l'ensemble collet extérieur 17 - frette 16.According to the embodiment shown, the disassembly is carried out by a bayonet type kinematics comprising a rotation followed by a translation of the outer collar 17 - hoop 16 assembly relative to the skirt 12. As a variant, only one rotation can be provided, the displacement device then being arranged to transform a rotational force on the hoop 16 into a translational movement of the outer collar 17 - hoop 16 assembly.

Pour éviter un démontage intempestif de l'ensemble système de fixation - pompe 3, le dispositif de déplacement peut comprendre des moyens de verrouillage du collet extérieur 17 en position basse, lesdits moyens étant désactivés par application d'un effort seuil.To avoid untimely dismantling of the fixing system - pump 3 assembly, the displacement device may comprise means for locking the outer collar 17 in the low position, said means being deactivated by application of a threshold force.

En outre, le dispositif de déplacement peut comprendre une butée de maintien du collet extérieur 17 en position haute sur le collet intérieur 8. Ainsi, dans la position de démontage de la figure 7, il est possible de retirer de façon unitaire l'ensemble système de fixation - pompe 3 par traction sur la frette 16.In addition, the displacement device may include a stop for maintaining the outer collar 17 in the high position on the inner collar 8. Thus, in the position for dismantling the figure 7 , it is possible to remove the entire fixing system - pump 3 unit by pulling on the band 16.

Selon une réalisation, les collets 8, 17 sont coaxiaux, le collet extérieur 17 présentant une portée intérieure axiale 17a et le collet intérieur 8 présentant une portée extérieure axiale 8a entourée par ladite portée intérieure, le dispositif de déplacement étant prévu entre lesdites portées.According to one embodiment, the collars 8, 17 are coaxial, the outer collar 17 having an axial inner bearing surface 17a and the inner collar 8 having an axial outer bearing surface 8a surrounded by said inner bearing surface, the displacement device being provided between said bearing surfaces.

En particulier, le dispositif de déplacement peut comprendre au moins une saillie 18 solidaire d'une des portées 17a, 8a, ladite saillie étant montée dans au moins une glissière 19 solidaire de l'autre portée 8a, 17a, le glissement de la saillie 18 dans la glissière 19 induisant le déplacement du collet extérieur 17 depuis sa position basse vers sa position haute.In particular, the displacement device can comprise at least one projection 18 integral with one of the bearing surfaces 17a, 8a, said projection being mounted in at least one slide 19 integral with the other bearing 8a, 17a, the sliding of the projection 18 in the slide 19 inducing the displacement of the outer collar 17 from its low position to its high position.

Dans les modes de réalisation représentés, la portée intérieure 17a présente deux saillies 18 diamétralement opposées, une glissière 19 pour chacune desdites saillies étant formée sur la portée extérieure 8a. En relation avec les figures 2 et 3, les glissières 19 présentent :

  • une partie périphérique 20 qui s'étend sur un secteur de la portée extérieure 8a, ladite partie périphérique n'étant pas traversante ; et
  • une partie supérieure axiale 21 traversante dans la portée extérieure 8a, ladite partie comprenant une ouverture supérieure 22 et communicant en partie inférieure dans la partie périphérique 20.
In the embodiments shown, the internal bearing surface 17a has two diametrically opposed projections 18, a slide 19 for each of said projections being formed on the external bearing surface 8a. In relation to figures 2 and 3 , the slides 19 have:
  • a peripheral part 20 which extends over a sector of the outer surface 8a, said peripheral part not being through; and
  • an upper axial part 21 passing through the outer bearing surface 8a, said part comprising an upper opening 22 and communicating in the lower part in the peripheral part 20.

Ainsi, lorsque le collet extérieur 17 est en position basse, chaque saillie 18 est disposée dans l'extrémité borgne 23 de la partie périphérique 20. Ensuite, lors du démontage par actionnement en rotation de la frette 16, les saillies 18 glissent dans les parties périphériques 20 pour atteindre les parties supérieures axiales 21 et, par traction sur la frette 16, les saillies 18 glissent dans lesdites parties supérieures pour disposer le collet extérieur 17 en position haute. En particulier, la longueur axiale des parties supérieures 21 est suffisante pour libérer les moyens de fixation de la jupe 12.Thus, when the outer collar 17 is in the low position, each projection 18 is disposed in the blind end 23 of the peripheral part 20. Then, during disassembly by rotating the hoop 16, the projections 18 slide in the parts. peripheral 20 to reach the upper axial parts 21 and, by pulling on the hoop 16, the projections 18 slide in said upper parts to place the outer collar 17 in the high position. In in particular, the axial length of the upper parts 21 is sufficient to release the means for fixing the skirt 12.

En relation avec les figures 2, les parties périphériques 20 s'étendent dans un plan radial, le collet extérieur 17 restant alors en position basse lors du glissement des saillies 18 dans ces parties 20. En variante représentée sur la figure 3b, la partie périphérique 20 peut être inclinée vers le haut pour imprimer un mouvement ascendant au collet extérieur 17 lors du glissement de la saillie 18 dans cette partie 20. En variante non représentée, la glissière 19 peut être dépourvue de partie axiale, la partie périphérique 20 s'étendant alors de façon hélicoïdale pour déplacer le collet extérieur 17 depuis sa position basse vers sa position haute.In relation to figures 2 , the peripheral parts 20 extend in a radial plane, the outer collar 17 then remaining in the lower position during the sliding of the projections 18 in these parts 20. In a variant shown in FIG. figure 3b , the peripheral part 20 can be inclined upwards to impart an upward movement to the outer collar 17 during the sliding of the projection 18 in this part 20. In a variant not shown, the slide 19 can be devoid of an axial part, the peripheral part 20 then extending helically to move the outer collar 17 from its low position to its high position.

En relation avec les figures 8, les glissières 19 s'étendent sur un secteur de la portée extérieure 8a en présentant une partie axiale 19a et une partie hélicoïdale 19b, chaque saillie 18 étant disposée dans une partie axiale 19a pour guider le déplacement en translation du collet extérieur 17 depuis sa position haute vers sa position basse. Ensuite, lors du démontage par actionnement en rotation de la frette 16, les saillies 18 glissent dans les parties hélicoïdales 19b pour déplacer ledit collet extérieur en position haute.In relation to figures 8 , the slides 19 extend over a sector of the outer bearing surface 8a, presenting an axial part 19a and a helical part 19b, each projection 18 being arranged in an axial part 19a to guide the translational movement of the outer collar 17 from its position high to its low position. Then, during disassembly by actuation in rotation of the hoop 16, the projections 18 slide in the helical parts 19b to move said outer collar in the high position.

La glissière 19 peut présenter un logement 24 de retenue de la saillie 18, ledit logement formant moyen de verrouillage du collet extérieur 17 en position basse. Sur les figures 2 et 3, le logement 24 est formé au voisinage de l'extrémité borgne 23 de la partie périphérique 20.Slide 19 may have a housing 24 for retaining projection 18, said housing forming means for locking the outer collar 17 in the low position. On the figures 2 and 3 , the housing 24 is formed in the vicinity of the blind end 23 of the peripheral part 20.

Sur les figures 2 et 3b, le logement 24 s'étend radialement pour permettre la disposition de la saillie 18 à l'intérieur de lui, le passage du rebord arrière dudit logement par la saillie 18 nécessitant un effort seuil de déverrouillage du dispositif de déplacement. Selon la figure 3b, le rebord arrière peut être pourvu d'un bossage radial 25 pour fiabiliser la disposition de la saillie 18 dans le logement 24 en augmentant l'effort de déverrouillage.On the figures 2 and 3b , the housing 24 extends radially to allow the provision of the projection 18 inside it, the passage of the rear edge of said housing through the projection 18 requiring a threshold force for unlocking the displacement device. According to figure 3b , the rear rim may be provided with a radial boss 25 to make the arrangement of the projection 18 more reliable in the housing 24 by increasing the unlocking force.

Selon la figure 3a, le logement 24 est délimité par bossage 26 qui s'étend axialement dans la partie périphérique 20, le passage de la saillie 18 sur ledit bossage fiabilisant le verrouillage et conférant l'effort nécessaire pour le déverrouillage.According to figure 3a , the housing 24 is delimited by boss 26 which extends axially in the peripheral part 20, the passage of the projection 18 over said boss making the locking more reliable and providing the force necessary for unlocking.

En relation avec les figures 8, le logement 24 est formé entre un bossage radial 25 formé à la jonction entre les parties axiale 19a et hélicoïdale 19b de sorte à nécessiter un effort seuil de déverrouillage du dispositif de déplacement. En outre, la partie axiale 19a est pourvue d'une saillie 40 qui présente une face supérieure biseautée pour permettre le glissement de la saillie 18 sur elle lors du montage du collet extérieur 17 en position basse et une face inférieure anguleuse pour assurer le blocage axial de ladite saillie dans le logement 24 afin de verrouiller le collet extérieur 17 en position basse.In relation to figures 8 , the housing 24 is formed between a radial boss 25 formed at the junction between the axial 19a and helical 19b parts so as to require a threshold force for unlocking the displacement device. In addition, the axial part 19a is provided with a projection 40 which has a bevelled upper face to allow the sliding of the projection 18 on it during the assembly of the outer collar 17 in the low position and an angular lower face to ensure axial locking. of said projection in the housing 24 in order to lock the outer collar 17 in the low position.

En particulier, la saillie 40 est disposée de sorte que le rebord supérieur du collet intérieur 8 forme une portée de pré-positionnement du collet extérieur 17 en position haute. Par ailleurs, le bossage 40 présente une hauteur telle que la dimension axiale du logement 24 est légèrement inférieure à celle de la partie hélicoïdale 19b afin d'éviter un jeu de la saillie 18 dans le logement 24 tout en favorisant le glissement de ladite saillie dans ladite partie hélicoïdale.In particular, the projection 40 is arranged so that the upper rim of the inner collar 8 forms a pre-positioning bearing surface for the outer collar 17 in the high position. Furthermore, the boss 40 has a height such that the axial dimension of the housing 24 is slightly less than that of the helical part 19b in order to avoid play of the projection 18 in the housing 24 while promoting the sliding of said projection in said helical part.

La glissière 19 représentée est également pourvue d'un bossage radial intermédiaire 41 qui permet, en cas de démontage accidentel, de former un point dur sur la course de rotation afin d'alerter l'utilisateur avant que les moyens de fixation ne soient libérés.The slide 19 shown is also provided with an intermediate radial boss 41 which makes it possible, in the event of accidental dismantling, to form a hard point on the rotational stroke in order to alert the user before the fixing means are released.

En fin de course de démontage, la partie hélicoïdale 19b est pourvue d'un logement 42 dans lequel la saillie 18 est disposée. En particulier, le logement 42 est délimité latéralement par une butée 43 qui est agencée pour empêcher le retour de la saillie 18 dans la glissière 19 et donc le remontage de la pompe 3. En outre, le logement 42 présente un rebord inférieur 44 qui est agencé pour, même en cas d'appui axial sur le collet extérieur 17, empêcher la disposition de la frette 16 en position basse de fixation.At the end of the disassembly stroke, the helical part 19b is provided with a housing 42 in which the projection 18 is arranged. In particular, the housing 42 is delimited laterally by a stop 43 which is arranged to prevent the return of the projection 18 in the slide 19 and therefore the reassembly of the pump 3. In addition, the housing 42 has a lower rim 44 which is arranged for, even in the event of axial bearing on the outer collar 17, preventing the arrangement of the hoop 16 in the low fixing position.

Dans le mode de réalisation représenté, la frette 16 est montée en coulissement autour du collet extérieur 17 entre ses positions haute et basse, plus précisément autour de la portée intérieure 17a dudit collet. En particulier, un effort de serrage est prévu à l'interface entre la frette 16 et le collet extérieur 17.In the embodiment shown, the hoop 16 is slidably mounted around the outer collar 17 between its high and low positions, more precisely around the inner bearing surface 17a of said collar. In particular, a clamping force is provided at the interface between the hoop 16 and the outer collar 17.

Par ailleurs, le rebord supérieur du collet intérieur 8 présente un jonc radial 27 qui coopère avec un jonc radial 28 formé dans le rebord inférieur du collet extérieur 17 pour maintenir le collet extérieur 17 en position haute sur le collet intérieur 8 (figures 2b, 7).Furthermore, the upper rim of the internal collar 8 has a radial rod 27 which cooperates with a radial rod 28 formed in the lower rim of the external collar 17 to keep the external collar 17 in the high position on the internal collar 8 ( figures 2b , 7 ).

En relation avec les figures 2, les ouvertures 22 des glissières 19 débouchent dans le jonc radial 27. Ainsi, par déformation élastique du collet extérieur 17 qui est traversé par les parties axiales 21 des glissières 19, les saillies 18 peuvent être disposées dans les glissières 19 puis l'effort de serrage conféré par la frette 16 sur le collet extérieur 17 permet de fiabiliser la coopération des joncs 27, 28 pour pouvoir maintenir le collet extérieur 17 en position haute sur le collet intérieur 8. En particulier, le maintien peut être suffisant pour résister à un effort de traction sur la frette 16 lors du démontage de l'ensemble système de fixation - pompe 3.In relation to figures 2 , the openings 22 of the slides 19 open into the radial ring 27. Thus, by elastic deformation of the outer collar 17 which is crossed by the axial parts 21 of the slides 19, the projections 18 can be arranged in the slides 19 and then the force of tightening provided by the hoop 16 on the outer collar 17 makes it possible to make the cooperation of the rods 27, 28 more reliable in order to be able to keep the outer collar 17 in the high position on the inner collar 8. In particular, the support may be sufficient to withstand a force traction on the hoop 16 when removing the mounting system - pump assembly 3.

En relation avec les figures 8, les parties axiales 19a ainsi que le logement 42 débouchent dans le jonc radial 27 de sorte à permettre le pré-positionnement du collet extérieur 17 en position haute et le maintien dudit collet sur le collet intérieur 8 après démontage.In relation to figures 8 , the axial parts 19a as well as the housing 42 open out into the radial ring 27 so as to allow the pre-positioning of the outer collar 17 in the high position and the maintenance of said collar on the inner collar 8 after removal.

Par ailleurs, pour entrainer en déplacement l'ensemble collet extérieur 17 - frette 16 relativement à la jupe 12, l'effort d'actionnement, notamment en rotation, du dispositif de déplacement est inférieur à celui de déplacement du manchon 7.Furthermore, to drive the assembly of the outer collar 17 - hoop 16 relative to the skirt 12 in movement, the actuation force, in particular in rotation, of the displacement device is less than that of displacement of the sleeve 7.

Pour ce faire, on peut prévoir que le serrage à l'interface entre la frette 16 et le collet extérieur 17 soit supérieur au serrage à l'interface entre ladite frette et la jupe 12. Par exemple, le diamètre extérieur de la couronne 13 peut être légèrement inférieur à celui du collet extérieur 17.To do this, provision can be made for the tightening at the interface between the hoop 16 and the outer collar 17 to be greater than the tightening at the interface between said hoop and the skirt 12. For example, the outer diameter of the ring 13 can be slightly lower than that of the outer collar 17.

L'effort de déplacement du manchon 7 peut également être augmenté en prévoyant des zones de frottement. En particulier, dans le mode de réalisation représenté, le système de fixation comprend un joint d'étanchéité annulaire 29 qui est disposé dans le manchon 7 pour être d'une part en appui axial sur la paroi supérieure du col 2 et d'autre part en appui axial sur le prolongement de la paroi inférieure de l'épaulement rentrant 15, lesdits appuis conférant un effort résistif vis-à-vis de la rotation dudit manchon par rapport audit col.The displacement force of the sleeve 7 can also be increased by providing friction zones. In particular, in the embodiment shown, the fixing system comprises an annular seal 29 which is arranged in the sleeve 7 to be on the one hand in axial bearing on the upper wall of the neck 2 and on the other hand bearing axially on the extension of the lower wall of the re-entrant shoulder 15, said supports imparting a resistive force with respect to the rotation of said sleeve relative to said neck.

En outre, la paroi supérieure présente un jonc en relief 30 augmentant l'effort résistif, ce jonc pouvant être continu ou interrompu. En variante non représentée, le jonc peut être une gorge en creux. En variante, le corps de la pompe 3 peut être maintenu, éventuellement de manière étanche, dans l'ouverture du corps 1.In addition, the upper wall has a raised ring 30 increasing the resistive force, this ring possibly being continuous or interrupted. In a variant not shown, the ring may be a hollow groove. As a variant, the body of the pump 3 can be maintained, optionally in a sealed manner, in the opening of the body 1.

Par ailleurs, le col 2 et/ou le manchon 7 peuvent être pourvus de moyens réciproques de retenue en rotation, l'effort de retenue conféré par lesdits moyens étant supérieur au couple nécessaire pour actionner en rotation le collet extérieur 17 depuis sa position basse vers sa position haute.Furthermore, the neck 2 and / or the sleeve 7 may be provided with reciprocal means for retaining in rotation, the retaining force imparted by said means being greater than the torque necessary to actuate the outer collar 17 in rotation from its lower position towards its high position.

En relation avec les figures 6, le col 2 présente au moins une butée 31 d'arrêt en rotation des griffes 14 en position rabattues. Sur la figure 6a, des butées d'arrêts sont formés sous le col 2, la section de ces butées pouvant être rectangulaire ou triangulaire. En particulier, le nombre de butées d'arrêt 31 peut être égal ou être un sous-multiple ou un multiple du nombre de griffes 14 afin d'éviter une mise en travers de la pompe 3 lors du positionnement du dispositif de fixation sur le col 2. Sur la figure 6a, quatre butées d'arrêt 31 sont prévues pour coopérer avec huit griffes 14.In relation to figures 6 , the neck 2 has at least one stop 31 for stopping the rotation of the claws 14 in the folded position. On the figure 6a , stops are formed under the neck 2, the section of these stops may be rectangular or triangular. In particular, the number of stops 31 may be equal or be a sub-multiple or a multiple of the number of claws 14 in order to avoid putting the pump 3 through when positioning the fixing device on the neck. 2. On the figure 6a , four stops 31 are provided to cooperate with eight claws 14.

La figure 6b présente la réalisation de butées 31 d'arrêt sur la périphérie extérieure du col 2. Plus précisément, la partie inférieure de la périphérie du col 2 présente deux cavités 32 diamétralement opposées, lesdites cavités débouchant sous ledit col. Les griffes 14 en position rabattues sont introduites dans lesdites cavités de sorte que les bords desdites cavités forment butée 31 d'arrêt.The figure 6b presents the production of stops 31 on the outer periphery of the neck 2. More precisely, the lower part of the periphery of the neck 2 has two diametrically opposed cavities 32, said cavities opening out under said neck. The claws 14 in the folded-down position are introduced into said cavities so that the edges of said cavities form a stopper 31.

Dans le mode de réalisation représenté, la frette 16 en position basse et le collet extérieur 17 présentent des moyens de solidarisation réciproque. Ainsi, après disposition en position basse, la frette 16 est solidaire du collet extérieur 17 pour permettre leur déplacement conjoint, notamment en rotation.In the embodiment shown, the hoop 16 in the low position and the outer collar 17 have reciprocal securing means. Thus, after arrangement in the low position, the hoop 16 is integral with the outer collar 17 to allow their joint movement, in particular in rotation.

En outre, les moyens de solidarisation sont interrompus sur l'interface entre la frette 16 en position basse et la jupe 12, de sorte à ne pas entraîner le manchon 7 en déplacement conjointement à l'ensemble collet extérieur 17 - frette 16.In addition, the securing means are interrupted on the interface between the hoop 16 in the low position and the skirt 12, so as not to cause the sleeve 7 to move together with the outer collar 17 - hoop 16 assembly.

En relation avec la figure 4, les moyens de solidarisation comprennent des stries axiales 32 qui sont formées sur l'intérieur de la frette 16, sensiblement sur la moitié supérieure de la zone de coulissement de ladite frette. Les stries 32 sont agencées pour être incrustées dans le collet extérieur 17 lors du coulissement de la frette 16 en position basse, de sorte à fiabiliser l'entrainement en rotation dudit collet extérieur par ladite frette. En variante, la coopération de cannelures dans des nervures peut être utilisée.In relation to the figure 4 , the securing means comprise axial ridges 32 which are formed on the inside of the hoop 16, substantially on the upper half of the sliding zone of said hoop. The ridges 32 are arranged to be embedded in the outer collar 17 during the sliding of the hoop 16 in the low position, so as to make the rotational driving of said outer collar by said hoop more reliable. Alternatively, the cooperation of grooves in ribs can be used.

Par ailleurs, en position basse, l'extrémité inférieure des stries 32 s'étend en regard du collet extérieur 17 de sorte que lesdites stries ne sont pas incrustées dans la jupe 12. En outre, en position haute, l'extrémité inférieure des stries 32 peut être incrustée dans le collet extérieur 17 pour fiabiliser le maintien de la frette 16 en position lors du montage de l'ensemble système de fixation - pompe 3 sur le col 2.Furthermore, in the low position, the lower end of the ribs 32 extends opposite the outer collar 17 so that said ribs are not embedded in the skirt 12. Furthermore, in the high position, the lower end of the ribs 32 can be embedded in the outer collar 17 to make the retention of the band 16 in position more reliable when mounting the assembly of the fixing system - pump 3 on the collar 2.

En relation avec la figure 5a, l'extrémité inférieure des stries 32 présente des crans 33 qui peuvent être obtenus par percutage. Les crans 33 s'étendent intérieurement pour être engagés sous le collet extérieur 17 lorsque la frette 16 est en position basse.In relation to the figure 5a , the lower end of the ribs 32 has notches 33 which can be obtained by percussion. Notches 33 extend internally to be engaged under the outer collar 17 when the hoop 16 is in the low position.

Ainsi, on fiabilise la solidarisation de l'ensemble collet extérieur 17 - frette 16 tant en rotation qu'en traction et ce, sans réaliser des stries 32 de relief important et/ou de profil tranchant dans la frette 16, notamment réalisées par emboutissage d'un matériau métallique.Thus, the securing of the outer collar 17 - hoop 16 assembly is made more reliable, both in rotation and in traction, without producing ridges 32 of significant relief and / or of cutting profile in the hoop 16, in particular produced by stamping of 'a metallic material.
