Description

DISPOSITIF DE DISTRIBUTION A BAGUE DE FIXAΗON A EMMANCHEMENT CONIQUE DISTRIBUTION DEVICE WITH FIXING RING WITH CONICAL HANDLE
La présente invention concerne un dispositif de distribution de produit fluide destiné à être monté dans un col de réservoir, dont la paroi interne peut selon les cas être de forme conique évasée vers le haut. Plus particulièrement, la présente invention concerne une bague de fixation permettant de recevoir un corps d'organe de distribution -tel qu'une pompe, la bague comportant en outre une jupe d'emmanchage de forme correspondante à celle de la paroi du col de manière à s'adapter dans le col du réservoir.The present invention relates to a fluid dispenser device intended to be mounted in a tank neck, the internal wall of which may, depending on the case, be of conical shape flared upwards. More particularly, the present invention relates to a fixing ring making it possible to receive a body of a dispensing member - such as a pump, the ring further comprising a fitting skirt of a shape corresponding to that of the wall of the neck so to fit in the neck of the tank.
On connait par exemple du document DE-85608 un dispositif de distribution dans lequel une pompe est montée dans un bouchon à paroi externe conique. Ce bouchon à paroi externe conique est revêtu avec une enveloppe de caoutchouc. Le col du réservoir sur lequel le bouchon doit être adapté présente également un col à paroi interne conique en correspondance avec le bouchon. L'enveloppe en caoutchouc du bouchon a pour but d'améliorer la fixation et l'étanchéité du bouchon dans le col conique. Cependant, du fait que le contact d'étanchéité a lieu sur la totalité de la surface tronconique du bouchon, on a dû mal à enfoncer le bouchon dans le col conique. En effet, étant donné que la force de pression que l'on exerce sur le bouchon est repartie uniformément sur la totalité de la surface tronconique de contact, il s'ensuit que le bouchon n'est nulle part en contact de pression forte avec le col conique du réservoir. Un inconvénient majeur résulte de ce fait en ce que le bouchon ne tient pas très bien dans le col et peut s'en dégager. Par conséquent l'utilisation d'une enveloppe en caoutchouc ne permet pas une bonne fixation et une parfaite étanchéité.Document DE-85608, for example, discloses a dispensing device in which a pump is mounted in a plug with a conical outer wall. This plug with conical outer wall is coated with a rubber jacket. The neck of the reservoir to which the cap is to be fitted also has a neck with a conical internal wall corresponding to the cap. The purpose of the rubber cover of the stopper is to improve the fixing and sealing of the stopper in the conical neck. However, due to the fact that the sealing contact takes place over the entire frustoconical surface of the plug, it was difficult to push the plug into the conical neck. Indeed, given that the pressure force which is exerted on the plug is distributed uniformly over the entire frustoconical contact surface, it follows that the plug is nowhere in strong pressure contact with the conical neck of the tank. A major drawback therefore results from the fact that the plug does not hold very well in the neck and can be released therefrom. Therefore use of a rubber envelope does not allow a good fixing and a perfect sealing.
Un autre document US-3 937 366 divulgue un distributeur comprenant un réservoir à col parfaitement cylindrique dans lequel est engagée une bague de fixation recevant une pompe. Pour se faire, la bague de fixation présente une jupe d' emmanchage à paroi extérieure cylindrique. Pour améliorer la fixation de la bague dans le col du réservoir, il est prévu sur la jupe d ' emmanchage une nervure annulaire périphérique et sur la paroi interne du col du réservoir une rainure annulaire périphérique. Une fois la -bague de fixation montée dans le col du réservoir, le cordon annulaire périphérique vient s'engager dans la rainure annulaire périphérique. Les formes du cordon périphérique et de la rainure périphérique sont parfaitement complémentaires de sorte qu'aucune pression n'est exercée sur le cordon à l'intérieur de la rainure. Par conséquent, cet arrangement de cordon et de rainure ne contribue pas à améliorer l' étanchéité entre la bague de fixation et le col du réservoir, mais simplement à assurer une bonne fixation.Another document US Pat. No. 3,937,366 discloses a dispenser comprising a tank with a perfectly cylindrical neck in which is engaged a fixing ring receiving a pump. To do this, the fixing ring has a fitting skirt with a cylindrical outer wall. To improve the fixing of the ring in the neck of the reservoir, a peripheral annular rib is provided on the engagement skirt and on the internal wall of the neck of the reservoir a peripheral annular groove. Once the fixing ring is mounted in the neck of the reservoir, the peripheral annular bead engages in the peripheral annular groove. The shapes of the peripheral bead and the peripheral groove are perfectly complementary so that no pressure is exerted on the bead inside the groove. Consequently, this arrangement of bead and groove does not contribute to improving the seal between the fixing ring and the neck of the reservoir, but simply to ensuring good fixing.
La présente invention a pour but de remédier aux inconvénients de l'art antérieur précités en définissant un dispositif de distribution dont la bague de fixation permet un emmanchage parfaitement étanche et une fixation sure.The object of the present invention is to remedy the drawbacks of the aforementioned prior art by defining a dispensing device, the fixing ring of which allows perfectly tight fitting and secure fixing.
Pour ce faire, la présente invention propose un dispositif de distribution de produit fluide destiné à être monté dans un col de réservoir, ledit dispositif comportant un organe de distribution, tel qu'une pompe, comprenant un corps et une tige d' actionnement mobile dans ledit corps, et une bague de fixation comprenant un logement de réception pour recevoir ledit corps et une jupe d' emmanchage dont la paroi externe est de forme correspondante à celle de la paroi du col de manière à s'adapter dans ledit col du réservoir, la paroi externe de la jupe étant pourvue d'au moins un cordon d' étanchéité périphérique adapté à venir s'écraser contre la paroi interne du col de réservoir. Ainsi, 1 ' emmanchage est parfaitement étanche et solide étant donné que toute la force exercée pour 1 ' emmanchage de la bague ne résulte qu'en un contact annulaire très fort dû à l'écrasement du cordon contre la paroi interne du col. Contrairement au document allemand précité, le contact d' étanchéité ne se fait que sur un cercle et non sur une surface tronconique ce qui augmente la force de contact contre la paroi interne du col. En outre, contrairement au document américain précité, un contact parfaitement étanche est créé du fait que le cordon ne peut pas venir s ' encliqueter dans une rainure de forme correspondance mais au contraire est complètement écrasé contre la paroi interne du col.To do this, the present invention provides a fluid dispenser device intended to be mounted in a tank neck, said device comprising a dispensing member, such as a pump, comprising a body and a movable actuating rod in said body, and a fixing ring comprising a receiving housing for receiving said body and a fitting skirt whose external wall is of a shape corresponding to that of the wall of the neck so as to fit in said tank neck, the external wall of the skirt being provided with at least one peripheral sealing bead adapted to come crashing against the internal wall of the tank neck. Thus, the fitting is perfectly sealed and solid since all the force exerted for the fitting of the ring results only in very strong annular contact due to the crushing of the bead against the internal wall of the neck. Unlike the aforementioned German document, the sealing contact is made only on a circle and not on a frustoconical surface which increases the contact force against the internal wall of the neck. In addition, unlike the aforementioned American document, a perfectly sealed contact is created because the bead cannot snap into a groove of corresponding shape but, on the contrary, is completely crushed against the internal wall of the neck.
Selon une caractéristique avantageuse, la paroi externe conique de la jupe est pourvue de deux cordons d' étanchéité périphériques. En effet, le fait de prévoir deux cordons d' étanchéité sur la bague permet d'améliorer encore davantage la stabilité de la bague à l'intérieur du col. Les deux cordons d' étanchéité définissent ensemble deux cercles espacés de sorte que la bague ne peut plus basculer à l'intérieur du col. En outre, 1 ' étanchéité est également améliorée du fait du doublement de la barrière d ' étanchéité .According to an advantageous characteristic, the conical outer wall of the skirt is provided with two peripheral sealing beads. Indeed, the fact of providing two sealing beads on the ring makes it possible to further improve the stability of the ring inside the neck. The two sealing beads together define two spaced circles so that the ring can no longer tilt inside the neck. In addition, the seal is also improved due to the doubling of the seal barrier.
Selon une autre caractéristique, la jupe s'étend autour du corps avec un écart radial formant un espace annulaire. Le fait que la paroi interne de la bague n'est pas en contact avec le corps de l'organe de distribution permet à la jupe de se déformer vers l'intérieur lors de l'écrasement du ou des cordons à l'intérieur du col conique du réservoir. Selon un autre aspect de l'invention, la bague de fixation forme une collerette de guidage pour une tête d ' actionnement montée sur la tige d' actionnemen .According to another characteristic, the skirt extends around the body with a radial gap forming an annular space. The fact that the inner wall of the ring is not in contact with the body of the dispensing member allows the skirt to deform inwards when the cord (s) are crushed inside the neck conical of the tank. According to another aspect of the invention, the fixing ring forms a guide flange for an actuating head mounted on the actuating rod.
Selon une forme de réalisation, la paroi interne du col et la jupe d' emmanchage de la bague sont de forme conique évasée vers le haut.According to one embodiment, the internal wall of the neck and the engagement skirt of the ring are of conical shape flared upwards.
L'invention sera maintenant décrite plus amplement en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention. Sur les dessins : la figure 1 est une vue en coupe verticale à travers un organe -de distribution selon l'invention ; la figure 2 est une vue en coupe transversale de l'organe de distribution de la figure 1 monté sur un col de réservoir selon l'invention.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 view in vertical section through a dispensing member according to the invention; Figure 2 is a cross-sectional view of the dispensing member of Figure 1 mounted on a tank neck according to the invention.
Comme on peut le voir sur les figures, le dispositif de distribution de produit fluide selon l'invention comporte trois éléments constitutifs essentiels, à savoir un réservoir 4, un organe de distribution 2, et une bague de fixation 1 pour monter l'organe de distribution 2 dans le col du réservoir 4.As can be seen in the figures, the fluid dispenser device according to the invention comprises three essential constituent elements, namely a reservoir 4, a dispenser member 2, and a fixing ring 1 for mounting the member distribution 2 in the tank neck 4.
Le réservoir 4 définit un volume interne dans lequel du produit fluide est stocké et un col 40 à la partie supérieure du réservoir définissant un accès à l'intérieur du réservoir. Dans le cadre de l'invention, le col 40 du réservoir 4 présente une paroi interne 41 de forme cylindrique, comme visible sur les figures. En variante, la paroi interne 41 peut également être de forme conique évasée vers le haut. Avantageusement si le réservoir est en verre, pour obtenir une qualité de surface satisfaisante, cette paroi interne conique 41 peut être rodée.The reservoir 4 defines an internal volume in which the fluid product is stored and a neck 40 at the top of the reservoir defining an access to the interior of the reservoir. In the context of the invention, the neck 40 of the reservoir 4 has an internal wall 41 of cylindrical shape, as visible in the figures. As a variant, the internal wall 41 can also be of conical shape flared upwards. Advantageously, if the tank is made of glass, to obtain a satisfactory surface quality, this conical internal wall 41 can be ground in.
L'organe de distribution 2 peut être une pompe par exemple, mais on peut également envisager une valve. Dans l'exemple représenté, il s'agit d'une pompe 2 présentant un corps de pompe 20 dans lequel une tige d' actionnement 21 est mobile. La structure interne de la pompe n'est pas critique pour l'invention et ne sera par conséquent pas décrite. A l'extrémité supérieure de la tige d' actionnement 21, est montée une tête d ' actionnement 3 avantageusement pourvue d'un gicleur 35. En appuyant sur la tête d ' actionnement 3, la tige d' actionnement 21 est enfoncée dans le corps de pompe 20 ce qui entraîne un refoulement de produit fluide hors du corps de pompe à travers la tige d ' actionnement et enfin à travers le gicleur 35. Un tel fonctionnement de pompe est tout à fait classique.The dispensing member 2 can be a pump for example, but one can also consider a valve. In the example shown, it is a pump 2 having a pump body 20 in which an actuating rod 21 is movable. The internal structure of the pump is not critical to the invention and will therefore not be described. At the upper end of the actuating rod 21, is mounted an actuating head 3 advantageously provided with a nozzle 35. By pressing on the actuating head 3, the actuating rod 21 is pressed into the body pump 20 which causes a discharge of fluid from the pump body through the actuating rod and finally through the nozzle 35. Such pump operation is entirely conventional.
Pour la fixation de l'organe de distribution 2 sur le col 40 du réservoir 4, il est prévu selon l'invention une bague de fixation 1 qui comprend d'une part un logement de réception 12 pour recevoir le corps de pompe 20, avantageusement par encliquetage, et d'autre part une jupe d' emmanchage 10 qui s'étend à partir du logement de réception 12 vers le bas. Cette jupe d ' emmanchage 10 présente une paroi externe de forme correspondante à celle de la paroi du col, c'est-à-dire cylindrique sur les dessins, mais peut également être de forme conique, lorsque la paroi du col est conique, avec une taille et une conicité permettant une adaptation dans le col conique du réservoir. La bague de fixation peut donc être emmanchée en force sur le réservoir en engageant la jupe d ' emmanchage cylindrique ou conique 10 dans le col cylindrique ou conique 40 du réservoir. Selon l'invention, la paroi externe cylindrique ou conique 15 de la jupe d' emmanchage 10 est pourvue d'au moins un cordon d' étanchéité périphérique 14 adapté à venir s'écraser contre la paroi interne 41 du col de réservoir 40. Dans l'exemple représenté sur les figures, la paroi externe cylindrique 15 est pourvue de deux cordons d' étanchéité périphériques 14. Les deux cordons d' étanchéité périphériques 14 font donc saillie sur la paroi externe 15 de la jupe 10 sous la forme de petits bourrelets. En outre, les deux cordons d' étanchéité périphériques 14 sont distants l'un de l'autre d'une certaine distance, ce qui a des effets avantageux sur la stabilité de la bague comme on pourra le voir ci-après. La bague de fixation 1 forme également une bride annulaire 11 qui s'étend à partir de l'extrémité supérieure de la jupe d' emmanchage 10 vers l'extérieur. Cette bride annulaire 11 se termine par une collerette cylindrique de guidage adaptée au guidage de la tête d' actionnement 3 montée sur la tige d ' actionnement 1. Comme on peut le voir sur les figures, la tête d' actionnement 3 est formée avec une jupe 33 qui s'étend vers le bas en entourant la collerette cylindrique 13. Ainsi, lors de 1 ' actionnement de la tête d' actionnement 3, cette dernière est guidée par l'engagement de sa jupe sur la collerette 13. Pour permettre l'enfoncement de la tête d ' actionnement 3, la collerette 13 est formée avec un évidement 15 permettant l'engagement du gicleur 35. On se référera maintenant plus précisément à la figure 2 qui représente un organe de distribution monté dans un col cylindrique 40 à l'aide d'une bague de fixation 1 selon l'invention. Comme on peut le voir sur cette figure, la paroi externe 15 de la jupe 10 s'adapte parfaitement en contact avec la paroi interne 41 du col 40. En réalité, il peut exister entre ces deux parois un très faible écart imperceptible à l'oeil nu, mais qui ne nuit ni à la fixation ni à l' étanchéité du dispositif. En effet, du fait de la présence des deux cordons d' étanchéité périphériques 14, on a une fixation et une étanchéité parfaite de la bague de fixation dans le col 40 du réservoir. En position emmanchée, telle que représentée sur la figure 2, les deux cordons d' étanchéité périphériques 14 sont fortement écrasés contre la paroi interne 41 du col 40. L'écrasement de ces cordons 14 exercent une forte pression annulaire sur la paroi interne 41 du col 40. Les cordons d' étanchéité 14 sont presque complètement écrasés de telle sorte qu'ils ne font pratiquement plus saillie sur la paroi externe 15 de la jupe 10. On obtient ainsi une étanchéité parfaite et sure. De plus, étant donné qu'il y a deux cordons d' étanchéité 14, il est ainsi défini une double barrière d ' étanchéité. Quant à la fixation, le fait de la présence de deux cordons d' étanchéité améliore d'autant plus la fixation en ce que les deux cordons d' étanchéité définissent ensemble un cylindre parfaitement stable. De plus, comme mentionné ci-dessus, l'espacement des deux cordons contribue encore davantage à la stabilité en définissant une section cylindrique ou tronc conique plus importante. Bien qu'il soit envisageable dans le cadre de l'invention de ne prévoir qu'un seul cordon d' étanchéité, il est préférable de prévoir deux cordons d' étanchéité pour les raisons de stabilité et d' étanchéité susmentionnées. Il est également à noter que la jupe d' emmanchage 10 n'est pas en contact avec sa paroi interne du corps 20 de la pompe 2. Cela permet une déformation de la jupe 10 vers l'intérieur, référencée par 140 sur la figure 2, lors de l'écrasement vers l'intérieur des cordons d' étanchéité 14. On évite ainsi une déformation du corps de pompe 20 qui pourrait nuire à son fonctionnement.For fixing the dispensing member 2 to the neck 40 of the reservoir 4, there is provided according to the invention a fixing ring 1 which comprises on the one hand a receiving housing 12 for receiving the pump body 20, advantageously by snap-fastening, and on the other hand a coupling skirt 10 which extends from the reception housing 12 downwards. This engagement skirt 10 has an external wall of a shape corresponding to that of the wall of the neck, that is to say cylindrical in the drawings, but can also be of conical shape, when the wall of the neck is conical, with a size and a taper allowing an adaptation in the conical neck of the tank. The fixing ring can therefore be force fitted onto the reservoir by engaging the cylindrical or conical engagement skirt 10 in the cylindrical or conical neck 40 of the reservoir. According to the invention, the cylindrical or conical outer wall 15 of the engagement skirt 10 is provided with at least one peripheral sealing bead 14 adapted to be crushed against the inner wall 41 of the tank neck 40. In the example shown in the figures, the cylindrical outer wall 15 is provided with two peripheral sealing cords 14. The two sealing cords peripherals 14 therefore protrude from the outer wall 15 of the skirt 10 in the form of small beads. In addition, the two peripheral sealing beads 14 are spaced from each other by a certain distance, which has advantageous effects on the stability of the ring as will be seen below. The fixing ring 1 also forms an annular flange 11 which extends from the upper end of the engagement skirt 10 towards the outside. This annular flange 11 ends with a cylindrical guide flange suitable for guiding the actuation head 3 mounted on the actuation rod 1. As can be seen in the figures, the actuation head 3 is formed with a skirt 33 which extends downwards surrounding the cylindrical collar 13. Thus, during actuation of the actuation head 3, the latter is guided by the engagement of its skirt on the collar 13. To allow the 'depression of the actuating head 3, the flange 13 is formed with a recess 15 allowing the engagement of the nozzle 35. Reference will now be made more precisely to FIG. 2 which represents a dispensing member mounted in a cylindrical neck 40 to using a fixing ring 1 according to the invention. As can be seen in this figure, the external wall 15 of the skirt 10 adapts perfectly in contact with the internal wall 41 of the neck 40. In reality, there may exist between these two walls a very small difference imperceptible to the naked eye, but which does not harm either the fixing or the sealing of the device. Indeed, due to the presence of the two peripheral sealing beads 14, there is a perfect fixing and sealing of the fixing ring in the neck 40 of the tank. In the fitted position, as shown in FIG. 2, the two peripheral sealing cords 14 are strongly crushed against the internal wall 41 of the neck 40. The crushing of these cords 14 exert a strong annular pressure on the internal wall 41 of the neck 40. The sealing cords 14 are almost completely flattened so that they practically no longer protrude from the external wall 15 of the skirt 10. A seal is thus obtained perfect and safe. In addition, since there are two sealing beads 14, a double sealing barrier is thus defined. As for the fixing, the fact of the presence of two sealing beads further improves the fixing in that the two sealing beads together define a perfectly stable cylinder. In addition, as mentioned above, the spacing of the two beads contributes even more to the stability by defining a larger cylindrical section or conical trunk. Although it is conceivable in the context of the invention to provide only one sealing bead, it is preferable to provide two sealing cords for the reasons of stability and sealing mentioned above. It should also be noted that the engagement skirt 10 is not in contact with its internal wall of the body 20 of the pump 2. This allows deformation of the skirt 10 inwards, referenced by 140 in FIG. 2 , during the inward crushing of the sealing cords 14. This prevents deformation of the pump body 20 which could adversely affect its operation.
De préférence, le réservoir 4 pourra être réalisé en verre bien que d'autres matériaux ne sont pas exclus, et la bague de fixation 1 pourra être réalisée en matière plastique bien que d'autres matériaux ne sont également pas exclus. Avec un réservoir en verre et une bague en plastique, on assure un parfait écrasement du ou des cordons d' étanchéité contre la paroi interne 41 du col de verre 40. Une étanchéité améliorée est obtenue selon l'invention par l'écrasement du ou des cordons d ' étanchéité, et une fixation améliorée est obtenue par le doublement des cordons . Preferably, the reservoir 4 can be made of glass although other materials are not excluded, and the fixing ring 1 can be made of plastic although other materials are also not excluded. With a glass reservoir and a plastic ring, a perfect crushing of the sealing bead or cords is ensured against the internal wall 41 of the glass neck 40. Improved sealing is obtained according to the invention by crushing the or cords sealing, and improved fixing is obtained by doubling the cords.
