Description

La présente invention concerne un distributeur de produit fluide comprenant un réservoir à col et un organe de distribution, tel qu'une pompe ou une valve, monté sur le col pour extraire du produit fluide du réservoir. L'invention concerne plus particulièrement une bague de fixation dudit organe de distribution destinée à fixer ce dernier sur un col présentant un épaississement périphérique extérieur qui définit avec le reste du col un épaulement inférieur. Ce type de réservoir avec un tel col est largement répandu pour des pompes ou valves qui sont encliquetées sur le col en utilisant l'épaulement inférieur comme surface de retenue ou de butée.The present invention relates to a dispenser for fluid product comprising a neck reservoir and a member distribution, such as a pump or a valve, mounted on the neck to extract fluid from the reservoir. The invention relates more particularly to a ring fixing of said distribution member intended to fix this last on a neck with thickening outer device which defines with the rest of the neck a lower shoulder. This type of tank with such a neck is widely used for pumps or valves that are snapped onto the collar using the shoulder lower as retaining or abutment surface.

Le document EP-A-0 704 251 divulgue une bague de fixation comprenant des pattes d'encliquetage aux extrémités desquelles sont formés des ergots d'encliquetage destinés à venir se loger en-dessous de l'épaulement du col. Par la suite, une frette vient recouvrir la bague pour empêcher les ergots de se désengager d'en-dessous de l'épaulement. En effet, il est possible avec ce genre de dispositif de fixation de retirer la bague du col tant que la frette n'est pas montée. Les pattes d'encliquetage sont souples ce qui permet aux ergots de passer par-dessus l'épaississement pour atteindre la position d'encliquetage sous l'épaulement. Par conséquent, lors du montage de la bague sur un tel col, les pattes doivent se plier vers l'extérieur, ce qui augmente le diamètre utile de la bague lors du passage sur l'épaississement du col. En outre, la fixation définitive n'est atteinte que lorsque la frette est montée : la fixation nécessite donc deux pièces.Document EP-A-0 704 251 discloses a ring fastening including snap tabs ends of which lugs are formed latching intended to be housed below the shoulder of the neck. Thereafter, a fret comes cover the ring to prevent the pins from disengage from below the shoulder. Indeed, it is possible with this kind of fastening device remove the collar from the neck until the hoop is not climb. The snap tabs are flexible which allows lugs to pass over thickening to reach the snap position under the shoulder. Therefore, when mounting the ring on such a collar, the legs must bend towards the outside, which increases the useful diameter of the ring when passing over the thickening of the cervix. In addition, the final fixation is only achieved when the hoop is mounted: the attachment therefore requires two parts.

Le document US-A-4 773 553 divulgue un autre dispositif de fixation dans lequel la bague de fixation est réalisée dans un matériau fluable et comporte des pattes pourvues de têtes faisant initialement saillie vers l'extérieur. Il est ainsi possible de monter la bague sur un col sans déformer les pattes vers l'extérieur. La fixation finale est réalisée en engageant en force une frette sur la bague de telle sorte que les têtes saillantes vers l'extérieur sont ramenées vers l'intérieur en-dessous de l'épaulement du col par fluage de matière. Dans ce cas, il faut également deux pièces pour réaliser la fixation et de plus, il faut exercer une certaine force sur la frette pour faire fluer les têtes vers l'intérieur.Document US-A-4,773,553 discloses another device fixing in which the fixing ring is made in a flowable material and has tabs provided heads initially projecting outwards. he it is thus possible to mount the ring on a collar without deform the legs outward. Final fixation is achieved by forcibly engaging a hoop on the ring so that the heads projecting outwards are brought inward below the shoulder neck by material creep. In this case, also two pieces for fixing and more, you have to exert some force on the hoop to make the heads flow inward.

D'autre part, le document US-A-5 299 703 décrit un système de fixation de pompe dans lequel une bague comporte des pattes terminées par une tête formée par ourlage vers l'intérieur. Avant montage, les têtes ourlées sont repliées vers l'extérieur pour permettre le passage du col. Une fois en position sur le col du récipient, les têtes sont déformées vers l'intérieur à l'aide d'une frette. Ce système est analogue à celui du document US-A-4 773 553, hormis que la bague est en métal et que les têtes sont repliées vers l'intérieur et non fluées. Etant donné qu'il s'agit de métal, ce système peut s'apparenter à un sertissage puisque du métal est déformé de manière à réaliser un rétrécissement. Là encore, il est nécessaire d'utiliser un outil pour fixer la bague sur le col du réservoir.On the other hand, document US-A-5,299,703 describes a pump fixing system in which a ring has legs terminated by a head formed by inward hemming. Before mounting, the hemmed heads are folded out to allow passage of the cervix. Once in position on the container neck, the heads are deformed inward using a fret. This system is similar to that of the document US-A-4,773,553, except that the ring is made of metal and that the heads are folded inwards and not slit. Being since it is metal, this system can be similar crimping since metal is deformed so that shrink. Again, it is necessary use a tool to attach the ring to the neck of the tank.

La présente invention a pour but de remédier au inconvénients de l'art antérieur précité en définissant un dispositif de fixation dont la bague de fixation réalise la fixation définitive sans l'aide d'une frette rapportée et dont le montage de la bague n'engendre pas de déformation de la bague hors de ses dimensions normales de repos.The object of the present invention is to remedy the disadvantages of the aforementioned prior art by defining a fixing device of which the fixing ring realizes final fixation without the aid of an attached hoop and the mounting of the ring does not generate deformation of the ring outside its normal dimensions of rest.

Pour ce faire, la présente invention prévoit un dispositif de fixation pour un distributeur de produit fluide adaptable sur un réservoir formé avec un col et comprenant un organe de distribution monté sur le col du réservoir, ledit col formant un épaississement périphérique extérieur définissant avec le reste du col un épaulement inférieur, ledit dispositif de fixation comportant une bague de fixation pour fixer l'organe de distribution sur le col, la bague de fixation comportant une jupe périphérique qui s étend jusqu'en dessous dudit épaulement, ladite jupe est pourvue de rabats dont les extrémités libres pointent vers l'intérieur et vers le haut et viennent en contact de butée contre l'épaulement pour ainsi réaliser un encliquetage de la bague de fixation sur le col du réservoir. En effet, lors du passage de l'épaississement, les rabats sont situés dans la jupe sans faire saillie au-delà vers l'extérieur et peuvent ensuite être pliés ou prendre leur orientation d'encliquetage sous l'épaulement. Avantageusement, les rabats sont précontraints vers l'intérieur lors de la fabrication de la bague de fixation. Dans ce cas, les rabats reprennent automatiquement leur orientation d'origine précontrainte vers l'intérieur dès le passage de l'épaississement. En variante, les rabats peuvent être contraints vers l'intérieur une fois la bague en position sur le col. Dans ce cas, une opération ultérieure sera nécessaire pour replier les rabats en dessous de l'épaulement. Dans les deux cas, la fixation est assurée par la bague seule, sans nécessiter l'ajout d'une frette supplémentaire. Les extrémités des rabats en butée contre l'épaulement garantissent à eux seuls la fixation définitive.To do this, the present invention provides a fastening device for a product dispenser fluid adaptable to a reservoir formed with a neck and comprising a dispensing member mounted on the neck of the reservoir, said neck forming a thickening outer device defining with the rest of the neck a lower shoulder, said fixing device comprising a fixing ring for fixing the distribution on the neck, the fixing ring comprising a peripheral skirt which extends to below said shoulder, said skirt is provided with flaps, the free ends point inward and high and come into abutment contact against the shoulder to thus snap on the ring fixing on the tank neck. Indeed, during the thickening passage, the flaps are located in the skirt without protruding beyond to the outside and can then be folded or take their orientation snap under the shoulder. Advantageously, the flaps are preloaded inward when manufacture of the fixing ring. In this case, the flaps automatically return to their orientation original prestressed inward as soon as thickening. Alternatively, the flaps can be forced inwards once the ring in position on the collar. In this case, a subsequent operation will be necessary to fold the flaps below the shoulder. In both cases, the fixation is ensured by the ring alone, without requiring the addition of a fret additional. The ends of the flaps abutting against the shoulder alone guarantee the fixing definitive.

De préférence, les rabats présentent une épaisseur de paroi égale ou inférieure à celle de la jupe de manière à ne pas faire saillie hors de la jupe lors du passage des rabats sur l'épaississement périphérique du col. Il est ainsi possible de prémonter la bague de fixation dans une frette de garniture décorative et de monter ensuite cet ensemble sur un col de réservoir. En effet, alors que dans l'art antérieur, les pattes d'encliquetage doivent se déformer vers l'extérieur pour passer l'épaississement, dans la présente invention, les rabats ne sont jamais déformés vers l'extérieur, ce qui permet le prémontage d'une frette, purement décorative, étant donné qu'elle n'est pas nécessaire à la fixation de la bague sur le col.Preferably, the flaps have a thickness of wall equal to or less than that of the skirt so as to do not protrude out of the skirt when passing flaps on the peripheral thickening of the cervix. It is thus possible to pre-mount the fixing ring in a fret of decorative trim and then mount this together on a tank neck. Indeed, while in prior art, the latching tabs must be deform outward to pass the thickening, in the present invention, the flaps are never outwardly deformed, allowing pre-assembly a fret, purely decorative, since it is not necessary for fixing the ring on the collar.

La présente invention définit également un distributeur comportant un tel dispositif de fixation pour fixer l'organe de distribution sur le col du réservoir.The present invention also defines a dispenser comprising such a fixing device for attach the dispensing member to the tank neck.

L'invention sera maintenant plus amplement décrite en référence à la figure unique, donnant à titre d'exemple non limitatif, une coupe transversale à travers un distributeur selon une forme de réalisation de l'invention.The invention will now be described more fully in reference to the single figure, giving as an example nonlimiting, a cross section through a dispenser according to one embodiment of the invention.

Sur la figure unique, il n'a été représenté que la partie supérieure du distributeur qui comprend dans son ensemble un réservoir 1, un dispositif de fixation 20 et un organe de distribution 2.In the single figure, only the upper part of the dispenser which includes in its together a tank 1, a fixing device 20 and a distribution unit 2.

Le réservoir 1, qui peut être en plastique ou en verre, est formé avec un corps 13 servant à contenir du produit fluide et un col 10 à sa partie supérieure. On voit que le col 10 s'étend à partir du corps 13 avec une section cylindrique 14, puis forme un épaulernent 12 vers l'extérieur et se termine par une autre section cylindrique de diamètre supérieure formant un épaississement périphérique extérieur 11. L'épaulement 13 forme ainsi la transition entre l'épaississement 11 et le restant du col 14 qui fait la jonction avec le corps 1. La partie supérieure du col définit une surface annulaire 15 qui peut avantageusement être pourvue d'un cordon annulaire d'étanchéité 16 servant à améliorer l'étanchéité avec un joint de col 24 faisant l'étanchéité entre le col 10 et l'organe de distribution 2. The tank 1, which can be plastic or glass, is formed with a body 13 serving to contain fluid product and a neck 10 at its upper part. We sees that the neck 10 extends from the body 13 with a cylindrical section 14, then forms a shoulder 12 towards the outside and ends with another section cylindrical of larger diameter forming a outer peripheral thickening 11. The shoulder 13 thus forms the transition between the thickening 11 and the remaining from the neck 14 which makes the junction with the body 1. The upper part of the neck defines an annular surface 15 which can advantageously be provided with a cord sealing ring 16 used to improve sealing with a neck seal 24 sealing between the neck 10 and the distribution unit 2.

Dans l'exemple représenté, l'organe de distribution 2 est une pompe, mais une valve est tout aussi bien envisageable. La structure interne de la pompe ne sera pas décrite, car elle n'est pas critique pour l'invention. La pompe comprend un corps de pompe 25 et une tige d'actionnement 26 sur laquelle est montée une tête d'actionnement 27 équipée d'un gicleur 28. Pour la fixation de la pompe sur le col, il est prévu, en tant que dispositif de fixation, une bague de fixation 20 comportant un logement de réception dans lequel le corps de pompe 25 est encliqueté en force et une jupe périphérique 21 qui s'étend vers le bas. Le diamètre interne de la jupe 21 est égal ou légèrement supérieur au diamètre externe de l'épaississement 11 du col de sorte que la jupe 21 peut s'engager sur le col avec un jeu minimum afin de garantir la stabilité de la pompe.In the example shown, the distribution member 2 is a pump but a valve is just as good possible. The internal structure of the pump will not described because it is not critical to the invention. The pump comprises a pump body 25 and a rod actuator 26 on which a head is mounted actuator 27 fitted with a nozzle 28. For fixing the pump on the neck, it is provided as fixing device, a fixing ring 20 having a receiving housing in which the body pump 25 is snapped in force and a skirt device 21 which extends downwards. The diameter internal of skirt 21 is equal to or slightly greater than thickening outer diameter 11 of the neck so that the skirt 21 can engage on the collar with play minimum to guarantee the stability of the pump.

Selon l'invention, la jupe 21 est pourvue de rabats 22 dégagés dans la jupe dont les extrémités libres pointent en position d'encliquetage vers le haut et vers l'intérieur, de manière à venir en butée contre l'épaulement 12 du col. Les rabats 22 sont reliés à la jupe par leurs extrémités inférieures et sont coudés vers l'intérieur pour s'étendre jusqu'en contact de l'épaulement 12. A l'endroit de chaque rabat, la jupe définit une fenêtre dans laquelle le rabat respectif peut venir se loger lorsqu'il est déformé vers l'extérieur. L'épaisseur des rabats est avantageusement égale ou inférieure à l'épaisseur de paroi de la jupe 21, de sorte que les rabats peuvent venir se loger dans les fenêtres sans faire saillie ni vers l'intérieur ni vers l'extérieur. Les rabats peuvent donc être entièrement compris dans leurs fenêtres respectives. Les rabats peuvent être précontraints avec cette orientation vers l'intérieur ou être initialement logés dans les fenêtres respectives de la jupe et seulement ensuite pliés dans leur position d'encliquetage définitive. De préférence, les rabats sont formés d'origine avec leur orientatior vers l'intérieur, car ceci permet d'éviter une opératior ultérieure de pliage des rabats vers l'intérieur en-dessous de l'épaulement 12 du col. Les rabats, et de ce fait la bague elle-même, seront de préférence moulés en matière plastique dans l'état représenté sur la figure unique. Dans ce cas, la bague 20 comporte des fenêtres 201 formées à la verticale de chaque rabat 22. Ces fenêtres ont permis lors du moulage de la bague le passage de broches de moule adaptées à définir les extrémités libres de rabats ainsi que les secteurs de paroi interne de le jupe situés au-dessus des rabats.According to the invention, the skirt 21 is provided with flaps 22 cleared in the skirt whose free ends point in the snap-up position and towards the interior, so as to abut against the shoulder 12 of the neck. The flaps 22 are connected to the skirt by their lower ends and are angled toward the interior to extend until contact with the shoulder 12. At the place of each flap, the skirt defines a window in which the respective flap can come and stay when it is deformed towards the outside. The thickness of the flaps is advantageously equal or less than the wall thickness of the skirt 21, so that the flaps can be accommodated in the windows without projecting inward or inward outside. The flaps can therefore be entirely included in their respective windows. The flaps can be prestressed with this orientation towards inside or be initially housed in windows respective of the skirt and only then folded in their final click position. Preferably, the flaps are originally formed with their orientatior inward, as this avoids an operatior subsequent folding of the flaps inwards below from the shoulder 12 of the neck. The flaps, and this made the ring itself, will preferably be molded in plastic in the state shown in the figure unique. In this case, the ring 20 has windows 201 formed vertically from each flap 22. These windows allowed during the molding of the ring the passage of mold pins adapted to define free ends of flaps as well as the inner wall sectors of the skirt located above the flaps.

Pour bien faire comprendre l'intérêt de l'invention, nous allons maintenant décrire une opération de montage de cette bague 20 sur un col 10. La bague 20, avec la pompe encliquetée dedans est engagée sur le col 10 du réservoir. La partie inférieure de la jupe vient coiffer l'épaississement 11 du col. En continuant l'enfoncement de l'épaississement 11 dans la jupe, les rabats 22 sont ensuite contraints dans leurs fenêtres respectives du fait du faible jeu qui existe entre la jupe et l'épaississement. Les rabats restent contraints dans leurs fenêtres respectives sans faire saillie vers l'extérieur jusqu'à ce qu'ils aient passé l'épaississement. Ils peuvent alors reprendre leur orientation initiale vers l'intérieur en-dessous de l'épaulement 12. Leurs extrémités libres sont alors en appui contre cet épaulement 12, réalisant ainsi un enciiquetage à cran d'arrêt, car il n'est alors plus possible de retirer la bague. Il est à noter que la fixation définitive est réalisée par la bague uniquement. Une frette décorative 23 peut venir coiffer la bague 20, mais elle ne contribue pas à la fixation ; elle ne remplit qu'un but esthétique. En outre, étant donné que les rabats ne font pas saillie vers l'extérieur lors de leur passage sur l'épaississement, il est possible de monter la frette sur la bague avant son encliquetage sur le col. On peut ainsi prémonter la frette sur la bague et monter le tout sur le col, ce qui simplifie le montage du distributeur.To clearly understand the interest of the invention, we will now describe an assembly operation of this ring 20 on a neck 10. The ring 20, with the pump snapped into it is engaged on the neck 10 of the tank. The lower part of the skirt comes to style the thickening 11 of the cervix. By continuing to push in thickening 11 in the skirt, the flaps 22 are then forced into their respective windows of the made of the weak play which exists between the skirt and thickening. The flaps remain constrained in their respective windows without projecting outwards until they have passed the thickening. They can then resume their original orientation towards the interior below the shoulder 12. Their free ends are then pressed against this shoulder 12, thus achieving a notched locking because it is no longer possible to remove the Ring. It should be noted that the final fixation is produced by the ring only. A decorative fret 23 can come over the ring 20, but it does not contribute at fixation; it only fulfills an aesthetic purpose. In addition, since the flaps do not protrude towards the outside as they pass over the thickening it is possible to mount the hoop on the ring before snap on collar. We can thus pre-mount the fret on the ring and mount everything on the collar, which simplifies the mounting of the dispenser.
