Description

La présente invention concerne un organe de fixation pour fixer une dispositif de distribution, tel qu'une pompe ou une valve sur le col d'un réservoir. En effet, pour fixer le corps d'une pompe par exemple sur le col d'un flacon, il est nécessaire d'utiliser une pièce de liaison qui peut se présenter sous la forme d'une bague ou d'une tourrette de fixation, ou encore sous la forme d'une capsule sertie. La bague ou tourrette encliquetable ou vissable et la capsule à sertir constituent les deux types de techniques les plus généralement utilisés dans l'industrie de la parfumerie et de la cosmétique.The present invention relates to a fixing member to fix a dispensing device, such as a pump or a valve on the neck of a tank. Indeed, to fix the body of a pump for example on the neck of a bottle it is necessary to use a connecting piece which can be present in the form of a ring or a tourrette of attachment, or in the form of a crimped capsule. The snap-on or screw-on ring or turner and the capsule crimping are the two most common types of techniques generally used in the perfume industry and of cosmetics.

La figure 2 ci-jointe représente un dispositif de distribution 4 équipé d'un organe de fixation sous la forme d'une bague plastique à encliqueter sur le col d'un réservoir. La figure 1 ci-jointe représente uniquement la bague de fixation 1. En général, les dispositifs de distribution, qui peuvent être soit une pompe soit une valve, sont constitués d'un corps 41 définissant à son extrémité supérieure une collerette 42 qui fait saillie vers l'extérieur. Au-delà de cette collerette 42, une tige d'actionnement 43 fait saillie vers le haut. Cette tige d'actionnement 43 est surmontée d'un poussoir 4 pourvu d'un gicleur 45. De manière classique, l'actionnement du dispositif de distribution s'effectue en poussant sur le poussoir 4 de manière à enfoncer la tige d'actionnement 43 dans le corps 41. Cette conception de dispositif de distribution et tout à fait classique et n'est en rien critique pour la présente invention.Figure 2 attached shows a device for distribution 4 equipped with a fixing member in the form a plastic ring to snap onto the neck of a tank. Figure 1 attached shows only the fixing ring 1. In general, distribution, which can be either a pump or a valve, consist of a body 41 defining at its upper end a flange 42 which projects towards outside. Beyond this collar 42, a rod actuator 43 projects upwards. This rod actuation 43 is surmounted by a pusher 4 provided with a nozzle 45. Conventionally, the actuation of the dispensing device is carried out by pushing on the pusher 4 so as to push the actuating rod 43 in body 41. This device design distribution and quite classic and is nothing critical for the present invention.

Pour la fixation d'un tel dispositif de distribution 4 sur le col d'un réservoir (non représenté), la bague de fixation utilisée 1 comprend d'une part des moyens de fixation sur le col du récipient et d'autre part des moyens pour recevoir le corps 41 du dispositif de distribution 4. Dans cette bague 1 de l'art antérieur, les moyens de fixation se présentent sous la forme de pattes d'encliquetage 12 pourvues à leurs extrémités inférieures de têtes d'encliquetage 13 qui font saillie vers l'intérieur. Les pattes d'encliquetage 12 sont suffisamment flexibles pour permettre aux têtes d'encliquetage 13 de passer sur le col du réservoir et venir s'encliqueter en-dessous dudit col. Comme on peut le voir sur la figure 2, la fixation définitive de la bague 1 sur le col s'effectue au moyen d'une frette de blocage 3 qui vient recouvrir la bague de fixation 1 de sorte que les têtes d'encliquetage 13 ne peuvent plus se déplacer radialement vers l'extérieur. Une fixation définitive est ainsi assurée. D'autre part, les moyens de réception de la bague de fixation 1 pour le corps 41 du dispositif de distribution 4 se présentent sous la forme d'un logement d'encliquetage 17, dans lequel la collerette 42 du corps 41 est engagée en force. Ce logement d'encliquetage 17 est formé par une paroi cylindrique 16 qui est reliée à son extrémité inférieure aux pattes d'encliquetage 12 par l'intermédiaire d'une bride annulaire 11 et qui se prolonge à son extrémité supérieure par une autre bride annulaire 13 percée en son centre par une ouverture de passage 19 pour la tige d'actionnement 43. Pour recevoir la collerette 42 par encliquetage dans le logement 17, la paroi cylindrique 16 est pourvue intérieurement de bourrelets d'encliquetage 15 qui rétrécissent localement l'entrée du logement d'encliquetage 17. Une telle conception pour une bague de fixation est tout à fait classique.For fixing such a distribution device 4 on the neck of a tank (not shown), the ring fixing used 1 comprises on the one hand means of fixing on the neck of the container and on the other hand means to receive the body 41 of the dispensing device 4. In this ring 1 of the prior art, the means of fixing are in the form of legs latching 12 provided at their lower ends with latching heads 13 which project inwards. Snap tabs 12 are flexible enough to allow the snap heads 13 to pass over the neck of the tank and snap below said collar. As can be seen in Figure 2, the attachment final ring 1 on the collar is done by a locking hoop 3 which covers the ring of fixing 1 so that the latching heads 13 do not can no longer move radially outwards. A final fixation is thus ensured. On the other hand, means for receiving the fixing ring 1 for the body 41 of the dispensing device 4 are presented under the form of a latching housing 17, in which the collar 42 of body 41 is engaged in force. This accommodation latching 17 is formed by a cylindrical wall 16 which is connected at its lower end to the legs latching 12 via an annular flange 11 and which is extended at its upper end by a other annular flange 13 pierced in the center by a passage opening 19 for the actuating rod 43. For receive the collar 42 by snap-fastening in the housing 17, the cylindrical wall 16 is internally provided with snap beads 15 which locally shrink the entrance to the snap-in housing 17. Such a design for a fixing ring is quite classic.

Depuis peu, on cherche à réduire la hauteur séparant l'extrémité supérieure du poussoir 4 de la bride annulaire de liaison 11 de la bague de fixation 1, et cela pour des raisons esthétiques. En effet, la surface inférieure de la bride de liaison 11 constitue la surface d'appui sur laquelle est disposé le joint d'étanchéité qui est placé sur le col du récipient. Par conséquent, la hauteur entre le poussoir 4 et la bride 11 constitue la hauteur de laquelle le dispositif de distribution fait saillie au-delà du col du récipient. Dans des domaines tels que la parfumerie et la cosmétique où l'aspect esthétique du distributeur est particulièrement important, il est fortement apprécié que cette hauteur soit réduite au minimum pour ne laisser que très peu apparaítre le dispositif de distribution au profit du réservoir. Pour un dispositif de distribution donné, cette hauteur poussoir/bride est directement déterminée par la hauteur de la paroi cylindrique 16 reliant la bride 11 à la bride 18, comme on peut le voir sur la figure 1.Recently, we are trying to reduce the height separating the upper end of the pusher 4 of the annular flange 11 of the fixing ring 1, and this for aesthetic reasons. Indeed, the lower surface of the connecting flange 11 constitutes the bearing surface on which is arranged the seal which is placed on the neck of the container. Therefore, the height between the pusher 4 and the flange 11 constitutes the height of which the dispensing device projects beyond the neck of the container. In areas such as perfumery and cosmetic where the aesthetic aspect of the dispenser is particularly important, it is highly appreciated that this height is reduced to a minimum to leave only very few appear the distribution system for the benefit of the tank. For a given distribution device, this push / flange height is directly determined by the height of the cylindrical wall 16 connecting the flange 11 to the flange 18, as can be seen in FIG. 1.

Par conséquent, le problème technique de la présente invention est de pouvoir réduire la distance séparant ces deux brides 11 et 18. Cela n'est pas possible avec une bague de fixation de l'art antérieur telle que représentée sur les figures 1 et 2. En effet, pour que le logement de réception par encliquetage 17 soit suffisamment élastique pour permettre une déformation radiale vers l'extérieur de la paroi cylindrique 16 lors du passage de la collerette 42 entre les bourrelets d'encliquetage 15, il faut impérativement que cette paroi cylindrique 16 présente une certaine hauteur. Il n'est donc pas possible de réduire cette hauteur, car au niveau de la bride de liaison 11 et au niveau de la bride supérieure 18, la paroi 16 ne présente aucune élasticité. Cette exigence d'élasticité de la paroi cylindrique 16 est également nécessaire lors du démoulage de la bague de fixation 1 lorsque il faut sortir la broche qui a servi au moulage du logement de réception 17. Si la paroi 16 ne présente pas une élasticité suffisante, il n'est pas possible d'extraire la broche du logement sans détériorer la bride de liaison 11. Pour ces deux raisons liées d'une part au démoulage et d'autre part à l'encliquetage de la collerette 42 du corps 41 du dispositif de distribution, il n'est pas possible techniquement de réduire la hauteur de la paroi cylindrique 16 d'une bague de fixation de l'art antérieur tel que représenté sur la figures 1 et 2.Therefore, the technical problem of this invention is to be able to reduce the distance between these two flanges 11 and 18. This is not possible with a ring fixing the prior art as shown in the Figures 1 and 2. Indeed, for the receiving housing by snap 17 is sufficiently elastic to allow a radial deformation towards the outside of the cylindrical wall 16 during the passage of the collar 42 between the snap beads 15, it is necessary it is imperative that this cylindrical wall 16 has a certain height. It is therefore not possible to reduce this height, because at the level of the connecting flange 11 and at level of the upper flange 18, the wall 16 does not have no elasticity. This requirement for elasticity of the wall cylindrical 16 is also necessary during the demolding of the fixing ring 1 when it is necessary to take out the spindle which was used to mold the receiving housing 17. If the wall 16 does not have sufficient elasticity, it is not possible to extract the spindle from the housing without damaging the connecting flange 11. For these two related reasons on the one hand on demolding and on the other hand on the snap-fastening of the flange 42 of the body 41 of the dispensing device, it it is not technically possible to reduce the height of the cylindrical wall 16 of an art fixing ring front as shown in Figures 1 and 2.

Le but de la présente invention est donc de pallier à cet inconvénient de l'art antérieur en définissant un organe de fixation dont la distance séparant la bride de liaison et la bride d'extrémité est réduite au minimum. The purpose of the present invention is therefore to overcome this disadvantage of the prior art by defining an organ the distance between the connecting flange and the end flange is minimized.

Ce but est atteint selon l'invention par un organe de fixation d'un dispositif de distribution sur le col d'un réservoir, comprenant une bague en matière plastique pourvue de moyens de fixation sur le col du réservoir et une coupelle métallique reçue dans la bague et pourvue de moyens de maintien du dispositif de distribution. L'utilisation combinée d'une bague plastique et d'une coupelle métallique offre les avantages cumulés d'une bague plastique (fixation aisée par encliquetage ou vissage) et d'une coupelle métallique (maintien du dispositif de fixation par sertissage). En effet, l'utilisation d'une bague plastique permet plusieurs modes de fixation simples et rapide ne nécessitant pas d'outillage particulier, et permet d'autre part un habillage aisé de la bague à l'aide d'une frette extérieure esthétique. Le sertissage du dispositif de fixation au moyen d'une coupelle métallique ne prend qu'une hauteur très faible étant donné que les problèmes d'élasticité liés à la paroi cylindrique de la bague de l'art antérieur ne se pose plus. En effet, la coupelle n'est déformée qu'une fois le dispositif de fixation en place pour réaliser le sertissage. Il est donc possible de déformer la coupelle sur une hauteur très réduite comparée à la hauteur de la paroi cylindrique de la bague da fixation de l'art antérieur. Par conséquent, l'opération de montage de l'organe de fixation sur le dispositif de distribution commence par le montage de la coupelle sur la collerette du dispositif de distribution. Cette opération s'effectue de préférence par sertissage bien évidement, bien que d'autres procédés de fixation ne sont pas exclus. Ensuite, la coupelle équipée de son dispositif de distribution est engagée dans la bague plastique dans laquelle elle peut être avantageusement reçue par encliquetage. Le dispositif de distribution équipé de son organe de fixation est alors prêt à être monté sur le col d'un réservoir en utilisant un joint d'étanchéité en interposition entre la coupelle et le col du réservoir. Selon le mode de fixation, la bague est soit vissée, soit encliquetée puis bloquée par une frette sur le col du réservoir.This object is achieved according to the invention by a fixing of a dispensing device on the neck of a tank, comprising a plastic ring provided fixing means on the tank neck and a metal cup received in the ring and provided with means maintaining the dispensing device. Use combined with a plastic ring and a metal cup offers the cumulative advantages of a plastic ring (fixing easy by snap-fastening or screwing) and a cup metallic (holding the fixing device by crimping). Indeed, the use of a plastic ring allows several simple and quick fixing methods requiring no special tools, and allows other share an easy dressing of the ring using a fret aesthetic exterior. The crimping of the fixing by means of a metal cup takes only one very low height since the problems of elasticity linked to the cylindrical wall of the ring the prior art no longer arises. Indeed, the cup is not distorted that once the fixing device in place for crimping. It is therefore possible to distort the cup on a very reduced height compared to the height of the cylindrical wall of the art fixing ring prior. Therefore, the mounting operation of the fixing member on the dispensing device begins by mounting the cup on the flange of the distribution device. This is done from preferably by crimping of course, although others fixation methods are not excluded. Then the cup equipped with its distribution device is engaged in the plastic ring in which it can be advantageously received by snap-fastening. The device distribution equipped with its fixing member is then ready to be mounted on the neck of a tank using a gasket sealing between the cup and the neck of the tank. Depending on the method of attachment, the ring is either screwed, either snapped on and then locked with a hoop on the tank neck.

Le dispositif de distribution équipé de sa coupelle constitue ainsi un sous-ensemble que l'on vient engager dans une bague plastique qui en fonction du mode de fixation choisi sera équipé de moyens d'encliquetage ou de vissage. La coupelle constitue ainsi un élément standard pour un dispositif de distribution donné, alors que la bague plastique permet une certaine modularité quant à sa technique de fixation sur le col. Il faut d'autre part noter qu'une telle bague plastique est extrêmement simple à mouler étant donné qu'elle est presque parfaitement cylindrique.The distribution device equipped with its cup thus constitutes a subset that we have just engaged in a plastic ring which, depending on the method of attachment chosen will be fitted with latching or screwing means. The cup thus constitutes a standard element for a given dispensing device, while the ring plastic allows a certain modularity as for its fixation technique on the collar. On the other hand, it should be noted that such a plastic ring is extremely simple to mold since it is almost perfectly cylindrical.

L'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 dessins :

The invention will now be described more fully with reference to the accompanying drawings which give by way of nonlimiting example an embodiment of the invention. In the drawings:
  • FIG. 1 is a sectional view through a fixing ring of the prior art,
  • FIG. 2 is a sectional view through a dispensing device equipped with the fixing ring of FIG. 1,

L'organe de fixation utilisé pour illustrer la présente invention représenté sur les figures 3 et 4 comprend deux pièces constitutives essentielles, à savoir une bague en matière plastique 1 et une coupelle métallique 2. Dans le mode de fixation ici décrit, la fixation définitive de la bague sur le col du réservoir est réalisée à l'aide d'une frette 3 qui se présente sous la forme d'un cylindre se terminant à son extrémité supérieure par un rebord annulaire vers l'intérieur. La mise en oeuvre d'une telle frette 3 ne constitue pas un élément essentiel de la présente invention, car elle dépend du mode de fixation de la bague sur le col du réservoir. En effet, dans certains types d'encliquetage, une telle frette n'est pas nécessaire. De même, dans le cas où la bague est à visser sur le col, l'utilisation d'une telle frette devient tout à fait superflue. Par conséquent, l'organe de fixation de la présente invention est essentiellement constitué par la bague plastique 1 et la coupelle métallique 1.The fastener used to illustrate this invention shown in Figures 3 and 4 includes two essential component parts, namely a ring made of plastic 1 and a metal cup 2. In the fixation method described here, the definitive fixation of the ring on the neck of the tank is made using a hoop 3 which is in the form of a cylinder is ending at its upper end with an annular rim towards the inside. The implementation of such a hoop 3 does is not an essential element of the present invention, because it depends on how the ring is attached to the collar of the tank. Indeed, in certain types of snap, such a hoop is not necessary. Similarly, in the case where the ring is to be screwed on the collar, the use of a such a fret becomes entirely superfluous. Therefore, the fixing member of the present invention is essentially constituted by the plastic ring 1 and the metal cup 1.

La bague plastique 1 se présente sous la forme d'une pièce sensiblement cylindrique. Dans sa partie inférieure, la bague forme des pattes d'encliquetage 12 qui se terminent par des têtes d'encliquetage 13 qui se présentent sous la forme d'ergots qui font saillie vers l'intérieur. Les pattes 12 s'étendent donc individuellement vers le bas ce qui leur confère une certaine élasticité radiale. La partie supérieure de la bague plastique 1 forme un manchon 14 qui sert à masquer la coupelle 2 ainsi que la tige d'actionnement 43 du dispositif de distribution de manière à ce qu'au repos, l'extrémité inférieure du poussoir ne fasse pas saillie hors du manchon 14, et cela pour des raisons esthétiques. Le manchon 14 peut également servir de parois de guidage pour le poussoir 44. Au-dessus des pattes d'encliquetage 12 et en-dessous du manchon 14, la bague plastique 1 forme un logement de réception par encliquetage 122 défini entre une paroi annulaire inférieure 140 du manchon 14 et des dents d'encliquetage 120. Ce logement annulaire de réception 122 est destiné à la réception de la coupelle métallique 2.The plastic ring 1 is in the form of a substantially cylindrical part. In its lower part, the ring forms snap tabs 12 which terminate by latching heads 13 which appear under the shape of lugs that protrude inward. The paws 12 therefore extend individually downwards which gives a certain radial elasticity. The part upper part of the plastic ring 1 forms a sleeve 14 which used to hide the cup 2 as well as the rod actuation 43 of the dispensing device so as to that at rest, the lower end of the pusher does not not protruding from the sleeve 14, and this for reasons aesthetic. The sleeve 14 can also serve as walls guide for pusher 44. Above the legs latching 12 and below the sleeve 14, the ring plastic 1 forms a snap-on housing 122 defined between a lower annular wall 140 of the sleeve 14 and latching teeth 120. This housing reception ring 122 is intended for the reception of the metal cup 2.

La coupelle métallique 2 est formée avec une bride de liaison 21 dont l'extrémité périphérique 210 est adaptée à venir se loger par encliquetage dans le logement d'encliquetage 122 formé par la bague plastique 1. Lorsque la coupelle métallique 2 est montée sur le dispositif de distribution 4, notamment au niveau de la collerette saillante 42 que forme le corps 41 du dispositif de distribution, celle-ci forme un étranglement 22 en-dessous de la collerette 4 qui s'évase vers l'extérieur pour former un bourrelet 23 qui se prolonge par une bride supérieure 25 dans laquelle est formé le trou de passage pour la tige d'actionnement 43 du dispositif de distribution 4. L'étranglement 22, le bourrelet 23 et la bride supérieure 25 forment un logement dans lequel la collerette 42 est maintenue fixement. De préférence, la réception de la collerette 42 est réalisée par sertissage. Dans ce cas, la coupelle métallique 2 ne présente pas à l'état initial l'étranglement 22 qui n'est réalisé qu'après mise en place du dispositif de distribution par sertissage. Le sous-ensemble ainsi formé de la coupelle métallique 2 et du dispositif de distribution 4 est ensuite engagé dans la bague plastique 1 dans le sens de la flèche A sur la figure 4 jusqu'à ce que le bord périphérique 210 de la bride de liaison 21 vienne s'encliqueter à l'intérieur du logement 122 réalisé dans la bague 1. L'ensemble est alors prêt à être encliqueté sur le col d'un réservoir avec un joint interposé entre la bride de liaison 12 et le col du réservoir. Pour finir, et ce dans le présent exemple de réalisation, la frette 3 est engagée sur la bague plastique 1 dans le sens de la flèche B pour venir la recouvrir et empêcher les pattes d'encliquetage de se désengager d'en-dessous du col du réservoir.The metal cup 2 is formed with a flange of link 21 whose peripheral end 210 is adapted to snap into the housing snap 122 formed by the plastic ring 1. When the metal cup 2 is mounted on the distribution 4, in particular at the flange protruding 42 formed by the body 41 of the distribution, it forms a throttle 22 below of the collar 4 which flares outwards to form a bead 23 which is extended by an upper flange 25 in which the hole for the rod is formed actuating device 43 of the dispensing device 4. Throttle 22, bead 23 and upper flange 25 form a housing in which the collar 42 is fixedly held. Preferably, the reception of the flange 42 is produced by crimping. In this case metal cup 2 does not present in the initial state the throttle 22 which is only realized after installation distribution device by crimping. The subset thus formed from the metal cup 2 and the distribution device 4 is then engaged in the plastic ring 1 in the direction of arrow A in the figure 4 until the peripheral edge 210 of the flange of link 21 comes snap inside the housing 122 produced in the ring 1. The assembly is then ready to be snapped onto the neck of a tank with a seal interposed between the connecting flange 12 and the neck of the tank. Finally, in the present example of realization, the hoop 3 is engaged on the plastic ring 1 in the direction of arrow B to cover it and prevent snap tabs from disengaging from below tank neck.

Avec cet organe de fixation combiné plastique/métal, on cumule à la fois les avantages du plastique liés à son moulage et à son élasticité, et les avantages du métal liés à sa capacité de pliage (sertissage).With this combined plastic / metal fastener, we combines the advantages of plastic with its molding and its elasticity, and the benefits of metal related to its folding capacity (crimping).
