Description

DISPOSITIF DE FIXATION D ' UN ORGANE DE DISTRIBUTION SUR UN COL DE RECIPIENT DEVICE FOR FIXING A DISPENSING MEMBER ON A CONTAINER NECK
La présente invention concerne un dispositif de fixation d'un organe de distribution, tel qu'une pompe, sur le col d'un récipient contenant du produit à distribuer. Plus particulièrement, la présente invention concerne des dispositifs de fixation pour des distributeurs dans lesquels la pompe n'est pas fixée au récipient à l'aide d'une bague de fixation externe qui vient s ' encliqueter ou se sertir sur le col du récipient.The present invention relates to a device for fixing a dispensing member, such as a pump, to the neck of a container containing product to be dispensed. More particularly, the present invention relates to fixing devices for dispensers in which the pump is not fixed to the container with the aid of an external fixing ring which comes to snap or crimp on the neck of the container.
De tels dispositifs de fixation, particulièrement adaptés au distributeurs de produit de petite taille, sont connus dans l'état de la technique. Ainsi, par exemple, le document FR-2 719 292 divulgue un tel dispositif de fixation d'un organe de dosage dans un récipient contenant du produit à distribuer, dans lequel le corps de pompe est fixé directement dans le col du récipient à l'aide d'une virole qui vient s'emmancher à l'intérieur dudit corps de pompe, 1 ' emmanchement à force de cette virole dans le corps de pompe créant une force radiale qui maintient fixement le corps de pompe dans le col du récipient. Ce dispositif, qui est bien adapté pour certains distributeurs, peut s'avérer insuffisant ou non adapté pour d'autres types de distributeurs.Such fastening devices, particularly suitable for distributing small product, are known in the state of the art. Thus, for example, document FR-2 719 292 discloses such a device for fixing a metering member in a container containing product to be dispensed, in which the pump body is fixed directly in the neck of the container to the using a ferrule which comes to be fitted inside said pump body, the force fitting of this ferrule into the pump body creating a radial force which fixes the pump body firmly in the neck of the container. This device, which is well suited for certain distributors, may prove to be insufficient or unsuitable for other types of distributors.
Ainsi, en particulier, lorsque le même corps de pompe doit être fixé sur des cols de récipient de différents diamètres, le dispositif du document FR-2 719 292 ne s'adapte pas car le diamètre extérieur du corps de pompe doit environ correspondre au diamètre intérieur du col du récipient. D'autre part, bien que ce dispositif permet de compenser les tolérances de fabrication aussi bien du col de récipient que du corps de pompe, cette compensation est limitée du fait des matériaux utilisés pour le corps du récipient (en général du verre) et pour le corps de pompe (en général un matériau plastique rigide) .Thus, in particular, when the same pump body must be fixed to container necks of different diameters, the device of document FR-2 719 292 does not adapt because the outside diameter of the pump body must approximately correspond to the diameter inside the container neck. On the other hand, although this device makes it possible to compensate for the manufacturing tolerances both of the container neck and of the pump body, this compensation is limited due to the materials used for the container body (generally glass) and for the pump body (usually a rigid plastic material).
Le document FR-2 699 433 divulgue un dispositif de montage destiné à être facilement montable et démontable de manière similaire à un bouchon tronconique. Ce dispositif comporte une bague rigide fixée au corps de pompe et une ou plusieurs douilles en matière souple pour s'adapter à des cols de différents diamètres. Du fait que le dispositif doit être aisément démontable, il ne permet pas de réaliser une fixation sure et de garantir une parfaite étanchéité. De plus, ce dispositif comporte au moins deux éléments différents qui doivent coopérer, ce qui est désavantageux du point de vue des coûts de fabrication et de montage du distributeur de produit. La présente invention a pour but de fournir un dispositif de fixation qui surmonte les inconvénients précités, tout en fournissant les mêmes avantages, à savoir une économie de coût pour la fabrication et le montage du distributeur de produit. Cette limitation des coûts est particulièrement intéressante lorsque le distributeur est un échantillon, tel qu'un échantillon de parfum, qui doit être distribué gratuitement.Document FR-2 699 433 discloses a mounting device intended to be easily mounted and dismountable in a similar manner to a frustoconical plug. These measures comprises a rigid ring fixed to the pump body and one or more sockets made of flexible material to adapt to necks of different diameters. Due to the fact that the device must be easily removable, it does not make it possible to achieve a secure fixing and to guarantee a perfect seal. In addition, this device comprises at least two different elements which must cooperate, which is disadvantageous from the point of view of the costs of manufacturing and mounting the product dispenser. The present invention aims to provide a fixing device which overcomes the aforementioned drawbacks, while providing the same advantages, namely a cost saving for the manufacture and assembly of the product dispenser. This limitation of costs is particularly advantageous when the distributor is a sample, such as a perfume sample, which must be distributed free of charge.
La présente invention a aussi pour but de fournir un tel dispositif de fixation qui permet d'adapter le même organe de distribution dans des récipients ayant des cols de diamètres différents.The present invention also aims to provide such a fixing device which makes it possible to adapt the same dispensing member in containers having necks of different diameters.
La présente invention a encore pour but de fournir un tel dispositif de fixation qui est parfaitement sûr et étanche. En particulier, le dispositif de fixation ne doit pas être aisément démontable.The present invention also aims to provide such a fixing device which is perfectly safe and waterproof. In particular, the fixing device must not be easily removable.
La présente invention a donc pour objet un dispositif de fixation d'un organe de distribution, tel qu'une pompe, sur le col d'un récipient contenant du produit à distribuer, comportant un seul élément de fixation, réalisé en un matériau deformable, et disposé dans le col du récipient entre la surface intérieure dudit col du récipient et la surface extérieure du corps de l'organe de distribution, ledit élément de fixation étant à l'état monté du dispositif de fixation, déformé et/ou comprimé par l'emmanchement du corps de l'organe de distribution dans le col du récipient, de telle sorte qu'il exerce une force radiale sur ledit corps de l'organe de distribution et sur ledit col du récipient, ladite force radiale assurant une fixation sure et étanche de l'organe de distribution sur le col du récipient . De préférence, l'élément de fixation est une virole dont le diamètre extérieur correspond environ au diamètre intérieur du col du récipient et dont le diamètre intérieur est, avant emmanchement de l'organe de distribution, inférieur au diamètre extérieur du corps de l'organe de distribution.The present invention therefore relates to a device for fixing a dispensing member, such as a pump, to the neck of a container containing product to be dispensed, comprising a single fixing element, made of a deformable material, and disposed in the neck of the container between the inner surface of said neck of the container and the outer surface of the body of the dispensing member, said fixing element being in the assembled state of the fixing device, deformed and / or compressed by the fitting the body of the dispensing member into the neck of the container, so that it exerts a radial force on said body of the dispensing member and on said neck of the container, said radial force ensuring a secure and sealed fixing of the dispensing member on the neck of the container. Preferably, the fixing element is a ferrule whose external diameter corresponds approximately to the internal diameter of the neck of the container and whose internal diameter is, before fitting of the dispensing member, less than the outside diameter of the body of the member of distribution.
Avantageusement, ledit élément de fixation comporte une bride radiale à son extrémité supérieure qui repose sur le dessus du col du récipient, ladite bride retenant l'élément de fixation lors de l'emmanchement de l'organe de distribution.Advantageously, said fixing element comprises a radial flange at its upper end which rests on top of the neck of the container, said flange retaining the fixing element during the fitting of the dispensing member.
De préférence, ledit élément de fixation comporte à son extrémité inférieure des moyens de prise pour fixer ledit élément de fixation sous le col à l'intérieur du récipient après emmanchement de l'organe de distribution. En particulier, lesdits moyens de prise comportent un ou plusieurs renflements de matière qui, avant emmanchement de l'organe de distribution font saillie vers l'intérieur dudit élément de fixation, et qui, lors de l'emmanchement dudit organe de distribution sont forcés sous le col du récipient par le corps de l'organe de distribution.Preferably, said fixing element comprises at its lower end gripping means for fixing said fixing element under the neck inside the container after fitting of the dispensing member. In particular, said gripping means comprise one or more bulges of material which, before fitting of the dispensing member protrude towards the inside of said fixing element, and which, during the fitting of said dispensing member are forced under the neck of the container through the body of the dispensing member.
Avantageusement, le corps de l'organe de distribution comporte une partie inférieure de diamètre réduit qui n'agit pas ou peu sur lesdits moyens de prise de sorte que l'interaction entre l'organe de distribution et lesdits moyens de prise n'a lieu qu'en fin d'emmanchement.Advantageously, the body of the dispensing member has a lower portion of reduced diameter which has little or no effect on said gripping means so that the interaction between the dispensing member and said gripping means does not take place. only at the end of the fitting.
Selon un premier mode de réalisation, lesdits moyens de prise sont réalisés sous la forme de pattes comportant chacune à leur extrémité inférieure un renflement de matière deformable. Selon un second mode de réalisation, lesdits moyens de prise sont réalisés sous la forme d'un renflement annulaire de matière deformable prévu à l'extrémité inférieure de l'élément de fixation.According to a first embodiment, said gripping means are made in the form of tabs each having at their lower end a bulge of deformable material. According to a second embodiment, said gripping means are produced in the form of an annular bulge deformable material provided at the lower end of the fastening element.
Avantageusement, le corps de l'organe de distribution comporte une saignée externe qui, à l'état monté du dispositif après emmanchement de l'organe de distribution, est située au niveau desdits moyens de prise, une partie desdits moyens de prise étant reçue dans ladite saignée pour fixer l'organe de distribution par rapport audit organe de fixation. Avantageusement, l'élément de fixation est réalisé en un matériau souple deformable tel que du polyethylene ou un thermoplastique élastomère.Advantageously, the body of the dispensing member comprises an external groove which, in the assembled state of the device after fitting of the dispensing member, is located at the level of said gripping means, a part of said gripping means being received in said groove for fixing the dispensing member relative to said fixing member.

Different variants of the device of the invention are shown in the figures.
Ainsi, sur les figures 1 et 2 , il est représenté une première variante du dispositif de fixation de l'invention.Thus, in Figures 1 and 2, there is shown a first variant of the fixing device of the invention.
Dans cette variante, l'élément de fixation 20 est réalisé sous la forme d'une virole cylindrique, qui vient s'adapter sur et dans le col cylindrique 2 d'un récipient 1, généralement en verre. Cette virole cylindrique 20 comporte avantageusement une bride radiale 21 à son extrémité supérieure, c'est-à-dire son extrémité disposé au niveau du dessus 3 du col 2 du récipient 1. Cette virole 20 dans le récipient s'étend sur une partie ou sur la totalité de la hauteur du col 2.In this variant, the fixing element 20 is produced in the form of a cylindrical shell, which fits on and in the cylindrical neck 2 of a container 1, generally made of glass. This cylindrical shell 20 advantageously comprises a radial flange 21 at its upper end, that is to say its end disposed at the top 3 of the neck 2 of the container 1. This shell 20 in the container extends over a part or over the entire height of the neck 2.
Le corps de pompe 11 peut comporter une partie inférieure de diamètre réduit lia qui ne coopère pas avec ledit élément de fixation 20 lors de l'emmanchement. Ainsi, lorsque la pompe 10 est insérée dans le col du récipient, l'élément de fixation 20 n'est avantageusement déformé et/ou comprimé que par la partie de plus grand diamètre du corps de pompe 11, c'est-à-dire pendant seulement une partie de l'emmanchement. Cette déformation et/ou compression crée une force radiale qui s'exerce sur la paroi intérieure du col du récipient et sur le corps de pompe. Lorsque le dispositif de fixation est à l'état monté, tel que représenté sur la figure 2, la pompe 10 est maintenue en place par ladite force radiale exercée par la virole 20. La bride radiale 21 sert utilement pour maintenir la virole 20 en place sur le col du récipient lors de l'emmanchement du corps de pompe.The pump body 11 may include a lower part of reduced diameter 11a which does not cooperate with said fixing element 20 during fitting. Thus, when the pump 10 is inserted into the neck of the container, the fixing element 20 is advantageously deformed and / or compressed only by the part of larger diameter of the pump body 11, that is to say during only part of the fitting. This deformation and / or compression creates a radial force which is exerted on the interior wall of the neck of the container and on the pump body. When the fixing device is in the assembled state, as shown in FIG. 2, the pump 10 is held in place by said radial force exerted by the ferrule 20. The radial flange 21 is usefully used to hold the ferrule 20 in place on the neck of the container when fitting the pump body.
En référence à la figure 3, il est représenté une autre variante du dispositif de fixation de l'invention. Dans cette variante, la surface intérieure du col 2 du récipient 1 n'est pas cylindrique mais tronconique et l'élément de fixation 20 a une forme correspondante de sorte qu'une bride radiale comme décrite dans le mode de réalisation représenté sur les figures 1 et 2 , n'est pas nécessaire ici. En effet, de par la forme tronconique de 1 ' intérieur du col 2 du récipient, l'élément de fixation 20 est maintenu automatiquement en place dans le col 2 lors de l'emmanchement du corps de pompe 11.With reference to FIG. 3, another variant of the fixing device of the invention is shown. In this variant, the inner surface of the neck 2 of the container 1 is not cylindrical but frustoconical and the fixing element 20 has a corresponding shape so that a radial flange as described in the embodiment shown in Figures 1 and 2, is not necessary here. Indeed, due to the frustoconical shape of the interior of the neck 2 of the container, the fixing element 20 is automatically held in place in the neck 2 during the fitting of the pump body 11.
Avantageusement, le corps de pompe 11 peut comporter un trou d ' évent 50. Ce trou d ' évent 50 peut être disposé dans la partie supérieure du corps de pompe 11 et être relié au récipient par une rainure 51 ou tout autre moyen équivalent.Advantageously, the pump body 11 may include a vent hole 50. This vent hole 50 may be disposed in the upper part of the pump body 11 and be connected to the container by a groove 51 or any other equivalent means.
Cette rainure 51 peut être réalisée dans le corps de pompeThis groove 51 can be produced in the pump body
11 (fig. 1 et 2) ou dans l'élément de fixation 50 (fig. 3).11 (fig. 1 and 2) or in the fixing element 50 (fig. 3).
Un autre mode de réalisation préféré est représenté sur les figures 4 à 9. Dans ce mode de réalisation, l'élément de fixation 20 comporte à son extrémité inférieure des moyens de prise 25 adaptés à fixer l'élément de fixation 20, à l'état monté du dispositif, sous le col 2 à l'intérieur du récipient 1. Comme dans l'exemple représenté en référence aux figures 1 et 2 , l'exemple représenté sur les figures 4 et 5, comporte une virole cylindrique 20 qui s'adapte dans un col 2 de récipient également cylindrique. Bien entendu, ce mode de réalisation des figures 4 et 5 s'adapte également au mode de réalisation de la figure 3, où l'intérieur du col du récipient est tronconique. Comme représenté sur les figures 4 et 5 , les moyens de prise 25 comportent un ou plusieurs renflements de matière qui, avant emmanchement de l'organe de distribution, c'est- à-dire de la pompe, font saillie vers l'intérieur de l'élément de fixation 20, et qui lors de l'emmanchement de la pompe 10 sont forcés sous le col 2 du récipient 1 par le corps de pompe 11, comme représenté sur la figure 5.Another preferred embodiment is shown in FIGS. 4 to 9. In this embodiment, the fixing element 20 has at its lower end gripping means 25 adapted to fix the fixing element 20, at the mounted state of the device, under the neck 2 inside the container 1. As in the example shown with reference to Figures 1 and 2, the example shown in Figures 4 and 5, comprises a cylindrical shell 20 which s fits in a neck 2 of also cylindrical container. Of course, this embodiment of Figures 4 and 5 also adapts to the embodiment of Figure 3, where the inside of the container neck is frustoconical. As shown in FIGS. 4 and 5, the gripping means 25 comprise one or more bulges of material which, before the dispensing member, that is to say of the pump, protrudes inwards the fixing element 20, and which during the fitting of the pump 10 are forced under the neck 2 of the container 1 by the pump body 11, as shown in FIG. 5.
Ces moyens de prise 25 peuvent être réalisés soit sous la forme de pattes comportant chacune à son extrémité inférieure un renflement de matière deformable, soit sous la forme d'un renflement annulaire en matière deformable prévu à l'extrémité inférieure de l'élément de fixation 20. Avantageusement, le corps de pompe 11 comporte une partie inférieure de diamètre réduit lia qui ne coopère pas ou peu avec ledits moyens de prise 25. Ainsi, le déplacement de matière sous le col 2, c'est-à-dire la fixation de la virole 20 sous ledit col, se produit en fin d'emmanchement du corps de pompe 11 dans le col du récipient.These gripping means 25 can be produced either in the form of tabs each having at its lower end a bulge of deformable material, or in the form of an annular bulge of deformable material provided at the lower end of the fixing element 20. Advantageously, the pump body 11 comprises a lower part of reduced diameter 11a which does not cooperate or has little cooperation with said gripping means 25. Thus, the movement of material under the neck 2, that is to say the fixing of the ferrule 20 under said neck, occurs at the end of fitting of the pump body 11 in the neck of the container.
Les figures 6 à 9 représentent une première variante du dispositif des figures 4 et 5. Dans cette variante, le col 2 comporte une nervure périphérique 5 destinée à permettre l'encastrement de la bride 21 de l'organe de fixation 20 ainsi que de la collerette de la pompe 10.Figures 6 to 9 show a first variant of the device of Figures 4 and 5. In this variant, the neck 2 has a peripheral rib 5 intended to allow the mounting of the flange 21 of the fixing member 20 as well as the pump flange 10.
Avantageusement, le col 2 comporte également une partie tronconique 6 s ' évasant vers 1 ' extérieur à 1 ' extrémité supérieure de la surface intérieure du col 2. Cette partie tronconique 6 coopère avec la partie correspondante de l'organe de fixation 20 pour assurer une étanchéité totale après emmanchement du corps de pompe 11. En effet, de par l'emmanchement, l'organe de fixation 20 est tiré vers l'intérieur du col par le corps de pompe. Il se crée donc une forte étanchéité à la partie supérieure du dispositif, et en particulier sur la partie tronconique 6.Advantageously, the neck 2 also includes a frustoconical part 6 flaring outwards towards the outside at the upper end of the interior surface of the neck 2. This frustoconical part 6 cooperates with the corresponding part of the fixing member 20 to ensure a total tightness after fitting of the pump body 11. In fact, by fitting, the fixing member 20 is pulled towards the inside of the neck by the pump body. It is therefore created a strong seal at the upper part of the device, and in particular on the frustoconical part 6.
Les figures 8 et 9 représentent encore une autre variante du dispositif de fixation 4 et 5. Dans cette variante, le corps de pompe 11 comporte une saignée ou rainure 15, périphérique ou non, qui, à l'état monté du dispositif, est situé dans le col 2 au niveau des renflements de matière 25. Ainsi, après emmanchement du corps de pompe, une partie des renflements de matière pénètre dans cette saignée 15, par exemple par fluage, pour assurer la fixation du corps de pompe par rapport à l'organe de fixation 20. Ainsi, il est quasiment impossible de démonter la pompe alors que le montage est lui facilité.Figures 8 and 9 show yet another variant of the fixing device 4 and 5. In this variant, the pump body 11 has a groove or groove 15, peripheral or not, which, in the assembled state of the device, is located in the neck 2 at the level of the bulges of material 25. Thus, after fitting the pump body, a portion of the bulges of material enters this groove 15, for example by creep, to ensure the fixing of the pump body relative to the 'fastener 20. Thus, it is almost impossible to disassemble the pump while the assembly is facilitated.
Le dispositif de fixation de la présente invention présente les avantages suivants :The fixing device of the present invention has the following advantages:
1- l'utilisation d'un élément de fixation 20 en matériau souple deformable disposé entre le col 2 du récipient et le corps de pompe 11 permet d'adapter le même corps de pompe à des récipients 1 comportant des cols 2 de différents diamètres et/ou permet aussi de mieux compenser les tolérances de fabrication du col de récipient et/ou du corps de pompe .1- the use of a fastening element 20 made of deformable flexible material placed between the neck 2 of the container and the pump body 11 makes it possible to adapt the same pump body to containers 1 comprising necks 2 of different diameters and / or also makes it possible to better compensate for the manufacturing tolerances of the container neck and / or of the pump body.
2- l'emmanchement à force du corps de pompe 11 à l'intérieur de l'élément de fixation deformable 20 lors du montage du dispositif crée une déformation dudit élément de fixation 20 dans le sens de l'emmanchement, de sorte qu'à l'extrémité supérieure de l'élément de fixation, il se produit une étanchéité très forte entre 1 ' élément de fixation du corps de pompe et le col du récipient. Ceci est notamment le cas dans les modes de réalisation où l'élément de fixation 20 comporte une bride radiale 21 dont une partie est tirée à l'intérieur du col 2 de récipient lors de l'emmanchement du corps de pompe 11. L' étanchéité est encore augmentée si le col 2 comporte une partie supérieure tronconique 6 comme représenté sur les figures 6 à 9. Cette étanchéité très forte au niveau de l'extrémité supérieure du col du récipient permet de ménager une mise à l'air libre (non représentée) dans le corps de pompe 11 à l'intérieur du col 2 du récipient, celle-ci étant reliée au récipient par exemple à l'aide d'une rainure ménagée dans le corps de pompe 11. Il n'est pas nécessaire de mettre l'orifice d ' évent dans la partie de diamètre réduit lia du corps de pompe .2- the press fitting of the pump body 11 inside the deformable fixing element 20 during assembly of the device creates a deformation of said fixing element 20 in the direction of the fitting, so that at the upper end of the fixing element, there is a very strong seal between one fixing element of the pump body and the container neck. This is particularly the case in the embodiments where the fastening element 20 comprises a radial flange 21, part of which is pulled inside the neck 2 of the container during the fitting of the pump body 11. The seal is further increased if the neck 2 has a frustoconical upper part 6 as shown in Figures 6 to 9. This very strong seal at the upper end of the neck of the container makes it possible to provide an air vent (not shown) in the pump body 11 inside the neck 2 of the container, the latter being connected to the container for example by means of a groove formed in the pump body 11. It is not necessary to put the vent orifice in the reduced diameter part 11a of the pump body.
3- la présence des moyens de prise, ou renflement de matière 25, à l'extrémité inférieure de l'élément de fixation 20, permet à l'état monté du dispositif de fixer de manière inamovible la virole 20 à 1 ' intérieur du col du récipient de sorte qu'un démontage du dispositif nécessite une extraction à force du corps de pompe 11 avant de pouvoir enlever l'élément de fixation 20. Ceci assure une fixation très forte du corps de pompe 11 dans le col 2 du récipient 1. 3- the presence of the gripping means, or bulge of material 25, at the lower end of the fixing element 20, allows the assembled state of the device to fix the ferrule irremovable 20 inside the neck of the container so that disassembly of the device requires force removal of the pump body 11 before the fixing element 20 can be removed. This ensures very strong fixing of the pump body 11 in the neck 2 of the container 1.
