Description

ORGANE DE FIXATION POUR DISTUIBUTEUR DE PRODUIT FLUIDE ET DISTRIBUTEUR COMPORTANT UN TEL ORGANE FIXING MEMBER FOR FLUID PRODUCT DISPENSER AND DISPENSER COMPRISING SUCH A MEMBER
La présente invention concerne un organe de fixation pour fixer une pompe ou une valve sur le col d'un récipient. En général, l'organe de fixation comprend des moyens de réception pour recevoir le corps de la pompe ou de la valve et des moyens de fixation pour la fixation sur le col du récipient. Ce genre d'organe de fixation, très courant dans le domaine de la parfumerie, de la cosmétique et de la pharmacie, est plus souvent désigné sous le terme de bague de fixation.The present invention relates to a fixing member for fixing a pump or a valve to the neck of a container. In general, the fixing member comprises receiving means for receiving the body of the pump or of the valve and fixing means for fixing to the neck of the container. This type of fixing member, very common in the field of perfumery, cosmetics and pharmacy, is more often referred to as the fixing ring.
De manière classique, le corps de la pompe ou de la valve est reçu par encliquetage dans un manchon d'encliquetage formant un logement dans lequel le corps de la pompe ou de la valve, le plus souvent formé avec une collerette saillante, est reçu. Pour la fixation sur le col du récipient, l'organe de fixation comprend une jupe pourvue de profils internes adaptés au vissage ou à l' encliquetage. Il existe d'autre part des organes de fixation métalliques permettant une fixation par sertissage. Toutefois, la présente invention ne s'intéresse qu'aux organes de fixation en matière plastique utilisant les techniques de vissage ou d' encliquetage .Conventionally, the pump or valve body is received by snap-fastening into a snap-on sleeve forming a housing in which the pump or valve body, most often formed with a projecting flange, is received. For fixing to the neck of the container, the fixing member comprises a skirt provided with internal profiles suitable for screwing or snap-fastening. On the other hand, there are metal fasteners allowing fixing by crimping. However, the present invention is concerned only with plastic fasteners using screwing or snapping techniques.
Avec de telles bagues de fixation en plastique, on utilise couramment une frette d'habillage qui vient recouvrir au moins partiellement et le plus souvent entièrement la bague de fixation pour des raisons purement esthétiques. Dans certains cas, la frette d'habillage sert également de moyen de blocage lorsque la fixation sur le col du récipient est réalisée à l'aide de pattes d'encliquetage souples. Pour le maintien de la frette d'habillage sur la bague de fixation, il existe plusieurs techniques. L'une d'elles prévoit d'emmancher la frette d'habillage à force sur la bague de fixation de sorte qu'elle est maintenue simplement par les forces de frottement. Une autre technique prévoit de former la frette d'habillage avec des godrons sous la forme de nervures qui font saillie vers l'intérieur, destinés à venir en prise de frottement avec l'organe de fixation. Dans les deux cas, il est nécessaire d'avoir une épaisseur de paroi relativement importante pour la frette pour qu'elle ne se déforme pas lors de l'emmanchage à force. Par conséquent, la frette d'habillage qui est la plupart du temps métallique est formée avec une quantité significative de métal, ce qui induit un coût élevé. D'autre part, il y a toujours un risque que la frette s'enlève de la bague de fixation, ou du moins qu'elle tourne librement sur elle-même : ceci peut par exemple provenir d'une utilisation fréquente et prolongée du distributeur qui entraîne des jeux entre la frette et la bagueWith such plastic fixing rings, a cover band is commonly used which covers at least partially and most often entirely the fixing ring for purely aesthetic reasons. In certain cases, the covering band also serves as a locking means when the fixing on the neck of the container is carried out using flexible snap tabs. There are several techniques for maintaining the covering band on the fixing ring. One of them provides to press the covering band forcibly onto the fixing ring so that it is held simply by the friction forces. Another technique provides for forming the covering hoop with gadroons in the form of ribs which project inwards, intended to come into friction engagement with the fixing member. In both cases, it is necessary to have a relatively large wall thickness for the hoop so that it does not deform during force-fitting. Consequently, the covering hoop which is mostly metallic is formed with a significant amount of metal, which induces a high cost. On the other hand, there is always a risk that the hoop will be removed from the fixing ring, or at least that it will rotate freely on itself: this can for example come from frequent and prolonged use of the dispenser which causes play between the hoop and the ring
Dans l'art antérieur, le document FR 5 234 135 décrit, en référence à la figure 1, une pompe pourvue d'une bague de fixation sur laquelle est engagée une frette d'habillage La bague de fixation est réalisée en matière plastique moulée, et la frette d'habillage est réalisée en métal. La frette d'habillage est sertie sur la bague de fixation 9. Il n'est pas précisé a quel endroit est réalisé le sertissage. De toute évidence, le sertissage ne peut être réalisé que sur la partie cylindrique de la frette et de la bague, et ne peut en aucun cas, pour des raisons d'évidences techniques, être réalisé au niveau du rebord 8 de la frette d'habillage formée à son extrémité supérieure et qui vient reposer sur la bague de fixation En effet, pour qu'il y ait sertissage, il faut qu'il y ait déformation de matière dans la direction radiale visant à dimmuer le diamètre de la frette d'habillage 14. Ceci ne peut pas être réalisé au niveau du rabat supérieur.In the prior art, document FR 5 234 135 describes, with reference to FIG. 1, a pump provided with a fixing ring on which a covering hoop is engaged. The fixing ring is made of molded plastic, and the covering band is made of metal. The covering band is crimped onto the fixing ring 9. It is not specified where the crimping is carried out. Obviously, the crimping can only be carried out on the cylindrical part of the hoop and the ring, and can in no case, for reasons of technical obviousness, be carried out at the rim 8 of the hoop. covering formed at its upper end and which comes to rest on the fixing ring Indeed, for there to be crimping, it is necessary that there is deformation of material in the radial direction aiming to decrease the diameter of the hoop covering 14. This cannot be done at the top flap.
D'autre part, la figure 7a de ce même document décrit une autre pompe pourvue d'une bague de fixation similaire sur laquelle est montée une frette d'habillage similaire. La seule différence avec la frette d'habillage de la figure 1 réside dans le fait que la frette d'habillage de la figure 7a est pourvue d'un rabat rentrant qui s'étend à l'intérieur de la bague de fixation coaxialement à sa partie cylindrique.On the other hand, FIG. 7a of this same document describes another pump provided with a similar fixing ring on which is mounted a hoop of similar covering. The only difference with the covering hoop of FIG. 1 resides in the fact that the covering hoop of FIG. 7a is provided with a re-entrant flap which extends inside the fixing ring coaxially with its cylindrical part.
Dans le passage correspondant de la description, il n'est pas fait mention de la frette d'habillage et aucune référence numérique n'a été donnée à la frette sur la figure 7a. Il n'est donc pas mentionné que la frette d'habillage de la figure 7a est sertie sur la bague de fixation.In the corresponding passage of the description, no mention is made of the covering hoop and no numerical reference has been given to the hoop in FIG. 7a. It is therefore not mentioned that the covering band of FIG. 7a is crimped on the fixing ring.
La figure 1 enseigne de sertir la frette d'habillage sur la bague de fixation. La figureFigure 1 teaches to crimp the cover band on the fixing ring. The figure
7a enseigne de réaliser l'extrémité supérieure de la frette d'habillage avec un rabat rentrant. En combinant les deux enseignements, on obtient une frette d'habillage, avec un rabat7a teaches to produce the upper end of the covering hoop with a re-entrant flap. By combining the two teachings, we get a covering fret, with a flap
_*- rentrant qui est sertie sur la bague de fixation. Or, la figure 1 n'enseigne pas de réaliser le sertissage au niveau du rabat rentrant, pour la simple raison qu'il n'y a pas de rabat rentrant sur la frette d'habillage de la figure 1 Par conséquent, le problème technique qui sous-tend la présente invention (épaisseur de paroi de frette réduite) n'est pas évoqué dans ce document de l'art antérieur. Par conséquent, la solution la plus simple et la plus logique est de sertir la frette d'habillage au même endroit que celle de la figure 1, a savoir sur sa partie cylindrique extérieure_ * - re-entrant which is crimped on the fixing ring. However, FIG. 1 does not teach to carry out crimping at the level of the re-entrant flap, for the simple reason that there is no flap re-entering on the covering hoop of FIG. 1 Consequently, the technical problem which underlies the present invention (reduced hoop wall thickness) is not mentioned in this document of the prior art. Therefore, the simplest and most logical solution is to crimp the cover band in the same place as that of Figure 1, namely on its outer cylindrical part
La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant un organe de fixation dont la frette d'habillage utilise très peu de matériau, qui est facile à fabriquer et qui évite tout risque d'enlèvement ou de rotation de la frette sur la bague.The object of the present invention is to remedy the aforementioned drawbacks of the prior art by defining a fixing member whose covering band uses very little material, which is easy to manufacture and which avoids any risk of removal or rotation of the hoop on the ring.
Pour ce faire, la présente invention propose un organe de fixation pour fixer un dispositif de produit fluide tel qu'une pompe ou une valve sur un col d'un récipient, ledit organe comprenant une bague formant des moyens de réception pour recevoir le corps du dispositif de distribution et des moyens de fixation pour la fixation sur le col du récipient, ladite bague étant pourvue d'une frette d'habillage qui s'étend au moins partiellement sur l'extérieur de la bague, caractérisé en ce que ladite bague comprend une douille à l'intérieur de laquelle la frette est sertie. En sertissant la frette à l'intérieur de la douille, on assure une fixation fiable et solide qui ne nuit pas à l'esthétique de la frette.To do this, the present invention provides a fixing member for fixing a fluid product device such as a pump or a valve on a neck of a container, said member comprising a ring forming receiving means for receiving the body of the dispensing device and fixing means for fixing to the neck of the container, said ring being provided with a covering band which extends at least partially over the outside of the ring, characterized in that said ring comprises a sleeve inside which the hoop is crimped. By crimping the hoop inside the bushing, a reliable and solid fixing is ensured which does not harm the aesthetics of the hoop.
Selon une forme de réalisation, la douille s'étend vers le haut et comprend à proximité de son extrémité libre un renfort interne qui fait saillie radialement vers l'intérieur. D'autre part, la frette d'habillage forme un rabat vers l'intérieur qui s'étend jusqu'en dessous du renfort de la douille où il est serti. L'opération de montage de la frette sur l'organe de fixation est donc particulièrement simple, puisqu'il suffit d'engager la frette sur la bague avec un effort moindre puisqu'il n'est pas nécessaire que la frette soit emmanchée à force sur la bague. Il suffit ensuite de sertir la frette sur la bague au niveau du rabat de la frette qui est situé à l'intérieur de la douille. Il est à noter que l'organe de fixation selon l'invention est également avantageux en ce qui concerne les exigences au niveau des tolérances dimensionnelles au niveau de la frette et de la bague puisqu'il n'est pas nécessaire que la frette s'emmanche avec précision sur la bague.According to one embodiment, the sleeve extends upwards and comprises, near its free end, an internal reinforcement which projects radially inwards. On the other hand, the covering hoop forms an inward flap which extends to below the reinforcement of the sleeve where it is crimped. The operation of mounting the hoop on the fixing member is therefore particularly simple, since it suffices to engage the hoop on the ring with less effort since it is not necessary for the hoop to be force-fitted on the ring. Then simply crimp the hoop on the ring at the flap of the hoop which is located inside the sleeve. It should be noted that the fixing member according to the invention is also advantageous with regard to the requirements in terms of dimensional tolerances at the level of the hoop and the ring since it is not necessary for the hoop to precisely fits onto the ring.
Selon une autre caractéristique de l'invention, lorsque l'organe de fixation est destiné à être fixé sur un col comprenant un jonc d'étanchéité annulaire qui fait saillie vers le haut à partir de l'extrémité supérieure du col, ledit organe comprend un joint torique dont le diamètre interne est tel que son arête interne inférieure vient en contact d'étanchéité sur l'extérieur du jonc. Avantageusement, le joint, une fois l'organe fixé sur le col, est comprimé de telle sorte que le jonc vient en contact avec l'organe de fixation. De préférence, le diamètre interne du joint est sensiblement égal au diamètre externe du jonc. Avec un joint de cette configuration, qui peut être mis en œuvre indépendamment de la frette sertie, on gagne en hauteur étant donné que le joint n'est plus interposé entre le jonc et la bague de fixation. Le joint remplit ainsi son rôle d'étanchéité sans interférer sur la hauteur du distributeur.According to another characteristic of the invention, when the fixing member is intended to be fixed to a neck comprising an annular sealing ring which projects upwards from the upper end of the neck, said member comprises a O-ring whose internal diameter is such that its lower internal edge comes into sealing contact on the outside of the rod. Advantageously, the seal, once the member has been fixed to the neck, is compressed so that the rod comes into contact with the fixing member. Preferably, the internal diameter of the seal is substantially equal to the external diameter of the rod. With a seal of this configuration, which can be implemented independently of the crimped hoop, there is an increase in height since the seal is no longer interposed between the rod and the fixing ring. The seal thus fulfills its sealing role without interfering with the height of the dispenser.
La présente invention a également pour objet un distributeur de produit fluide comprenant un tel organe de fixation. La présente invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non-limitatif un mode de réalisation de l'invention. Sur les figures : la figure la est une vue en coupe transversale verticale à travers une pompe ou une valve équipée d'un organe de fixation selon l'invention, la figure 1b est une vue agrandie du détail encadré de la figure la montrant le sertissage de la frette sur la bague, la figure le est une variante de la figure lb, et la figure 2 est une vue agrandie montrant l'organe de fixation monté sur un col de récipient avec un joint.The present invention also relates to a fluid dispenser comprising such a fixing member. The present invention will now be described more fully with reference to the accompanying drawings which give by way of non-limiting example an embodiment of the invention. In the figures: FIG. 1a is a vertical cross-section view through a pump or a valve equipped with a fixing member according to the invention, FIG. 1b is an enlarged view of the framed detail of the figure showing the crimping of the hoop on the ring, FIG. 1c is a variant of FIG. 1b, and FIG. 2 is an enlarged view showing the fixing member mounted on a container neck with a seal.
En se référant tout d'abord à la figure la , on voit une pompe ou une valve 2 montée dans un organe de fixation la . La pompe ou la valve 2 comprend un corps 20 formant à son extrémité supérieure une collerette 23 qui fait saillie vers l'extérieur. Au-delà de cette collerette 23, la pompe ou la valve comprend une tige d'actionnement 21 surmontée d'une tête de distribution 22 éventuellement équipée d'un gicleur. La structure interne de la pompe ou de la valve n'étant pas critique pour la présente invention, elle ne sera pas décrite du tout.Referring first to Figure la, we see a pump or a valve 2 mounted in a fixing member la. The pump or the valve 2 comprises a body 20 forming at its upper end a flange 23 which projects outwards. Beyond this flange 23, the pump or the valve comprises an actuating rod 21 surmounted by a dispensing head 22 possibly fitted with a nozzle. Since the internal structure of the pump or the valve is not critical to the present invention, it will not be described at all.
L'organe de fixation selon l'invention comprend de manière conventionnelle une bague de fixation 11 et une frette d'habillage 12 qui recouvre entièrement l'extérieur de la bague 11.The fixing member according to the invention conventionally comprises a fixing ring 11 and a covering hoop 12 which entirely covers the outside of the ring 11.
La bague de fixation 11 comprend de manière classique un logement d'encliquetage 112 dans lequel la collerette saillante 23 du corps 20 de la valve ou de la pompe 2 est engagée par encliquetage. Ce logement d'encliquetage 112 se prolonge radialement vers l'extérieur par une bride de liaison 113. Cette bride de liaison 113 se prolonge vers le bas par une jupe de fixation 114 ici pourvue d'une tête d'encliquetage 115 destinée à coopérer avec le col 4 d'un récipient. Dans cette version, la technique utilisée est celle de l'encliquetage, mais on aurait également pu imaginer une bague de fixation avec une jupe 114 formant des filets de vissage interne destinée à coopérer avec un filetage externe formé sur le col du récipient. Selon l'invention, la bride de liaison 113 se prolonge également vers le haut par une douille 110 qui définit à proximité de son extrémité supérieure libre un renfort 111 qui fait saillie radialement vers l'intérieur. Ce renfort 111 peut se présenter sous la forme d'un cordon périphérique continu ou encore sous la forme de bossages régulièrement répartis sur la périphérie interne de la douille 110. Dans les deux cas nous parlerons d'un renfort 111.The fixing ring 11 conventionally comprises a latching housing 112 in which the protruding flange 23 of the body 20 of the valve or of the pump 2 is engaged by latching. This latching housing 112 is extended radially outwards by a connecting flange 113. This connecting flange 113 is extended downwards by a fixing skirt 114 here provided with a latching head 115 intended to cooperate with the neck 4 of a container. In this version, the technique used is that of the latching, but one could also have imagined a fixing ring with a skirt 114 forming internal screw threads intended to cooperate with an external thread formed on the neck of the container. According to the invention, the connecting flange 113 is also extended upwards by a bushing 110 which defines, near its free upper end, a reinforcement 111 which projects radially inwards. This reinforcement 111 can be in the form of a continuous peripheral bead or even in the form of regularly distributed bosses on the internal periphery of the sleeve 110. In both cases we will speak of a reinforcement 111.
Quant à la frette 12, elle comprend un corps 121 ici parfaitement cylindrique, qui se prolonge à son extrémité supérieure par un rabat 122. Le corps 121 et le rabat 122 forment ensemble un logement annulaire dans lequel vient s'insérer la douille 110 pourvue du renfort 111. Selon l'invention, la fixation de la frette 12 sur la douille 110 est effectuée par sertissage du rabat 122 à l'intérieur de la douille 110 en dessous du renfort 111. Les figures lb et le montrent deux versions différentes de sertissage possible du rabat 122 à l'intérieur de la douille 110 ; dans la figure lb , le rabat 122 -est simplement déformé contre la paroi interne de la douille 110, alors que dans la figure le, le rabat 122 est localement déformé de manière à venir mordre dans la douille 110. Le contact serré du rabat contre la paroi interne de la douille 110 empêche toute rotation de la frette sur la bague, alors que le renfort 111 empêche tout retrait de la frette par traction. On assure ainsi une fixation fiable et solide de la frette sur la bague. De plus, cela permet de réaliser la frette avec une épaisseur de paroi réduite, d'où une économie de métal. D'autre part, le corps 121 de la frette n'a pas besoin d'être formé avec un profil spécial adapté à la fixation sur la bague comme par exemple des godrons, et n'a pas non plus besoin d'être fabriqué avec une très grande tolérance étant donné que la fixation se fait au niveau du rabat. En outre, du fait que le sertissage se fait à l'intérieur de la douille, il est pratiquement invisible. De préférence, la frette d'habillage est montée sur la bague avant conditionnement, c'est-à-dire avant de monter la pompe ou la valve sur le col du réservoir.As for the hoop 12, it includes a body 121 here perfectly cylindrical, which is extended at its upper end by a flap 122. The body 121 and the flap 122 together form an annular housing in which is inserted the sleeve 110 provided with reinforcement 111. According to the invention, the hoop 12 is fixed to the sleeve 110 by crimping the flap 122 inside the sleeve 110 below the reinforcement 111. FIGS. 1b and 2b show two different versions of crimping possible flap 122 inside the sleeve 110; in FIG. 1b, the flap 122 is simply deformed against the internal wall of the socket 110, while in FIG. 1a, the flap 122 is locally deformed so as to bite into the socket 110. The tight contact of the flap against the internal wall of the sleeve 110 prevents any rotation of the hoop on the ring, while the reinforcement 111 prevents any withdrawal of the hoop by traction. This ensures reliable and solid fixing of the hoop on the ring. In addition, this allows the hoop to be produced with a reduced wall thickness, thereby saving metal. On the other hand, the body 121 of the hoop does not need to be formed with a special profile suitable for fixing to the ring such as for example gadroons, and also does not need to be manufactured with very great tolerance since the fixing is done at the flap. In addition, since the crimping takes place inside the sleeve, it is practically invisible. Preferably, the covering hoop is mounted on the ring before packaging, that is to say before mounting the pump or the valve on the neck of the tank.
Selon une autre caractéristique intéressante de l'invention, qui peut être mise en oeuvre indépendamment de la frette sertie, la bague 12 est pourvue d'un joint 3 spécialement adapté au montage de la bague sur un col 4 formé avec un jonc d'étanchéité annulaire 41.According to another advantageous characteristic of the invention, which can be implemented independently of the crimped hoop, the ring 12 is provided with a seal 3 specially adapted for mounting the ring on a neck 4 formed with a sealing ring annular 41.
Ce jonc 41, comme on le voit sur la figure 2, est situé sur l'extrémité supérieure du col 4 à partir de laquelle il fait saillie vers le haut. Le joint torique 3 selon l'invention présente un diamètre interne tel que son arête interne inférieure 31 vient en contact d'étanchéité avec une déformation éventuelle sur l'extérieur du jonc 41. Comme on peut le voir sur la figure 2, l'arête inférieure intérieure 31 du joint 3 est déformée contre la pente extérieure montante du jonc 41, ce qui contribue à une parfaite étanchéité à cet endroit. A l'opposé, l'arête extérieure supérieure du joint 3 est également déformée contre le coin formé par la bride de liaison 113 et la jupe 114. Ainsi, avec un joint torique particulièrement mince, on obtient une étanchéité parfaite. De plus, étant donné que le joint 3 ne s'étend pas entre le jonc 41 et la bride de liaison 1 13, il ne crée pas de surépaisseur à cet endroit de sorte que la bague de fixation peut venir en contact direct du jonc 41, ce qui contribue à réduire la hauteur totale du distributeur. This rod 41, as seen in Figure 2, is located on the upper end of the neck 4 from which it projects upwards. The O-ring 3 according to the invention has an internal diameter such that its lower internal edge 31 comes into sealing contact with a possible deformation on the outside of the rod 41. As can be seen in FIG. 2, the edge inner bottom 31 of the seal 3 is deformed against the rising outer slope of the rod 41, which contributes to a perfect seal at this location. In contrast, the upper outer edge of the seal 3 is also deformed against the corner formed by the connecting flange 113 and the skirt 114. Thus, with a seal particularly thin ring, a perfect seal is obtained. In addition, since the seal 3 does not extend between the ring 41 and the connecting flange 1 13, it does not create an allowance at this location so that the fixing ring can come into direct contact with the ring 41 , which contributes to reducing the total height of the dispenser.
