Description

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 fixing device a dispensing member, such as a pump, on the neck of a container containing product to be dispensed More in particular, the present invention relates to fixing devices for distributors in which the pump is not attached to the container with a ring of external fixing 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, l'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.Such fastening devices, particularly suitable for small product dispensers, are known in the state of the art. So, for example, the document FR-2 719 292 discloses such a fixing device a dosing device in a container containing product to be dispensed, in which the pump body is fixed directly into the container neck using a ferrule which is fitted inside said pump body, the press fitting of this ferrule in the body of pump creating a radial force which fixes the pump body in the container neck.

Ce dispositif, qui est bien adapté pour certains distributeurs, peut s'avérer insuffisant ou non adapté pour d'autres types de distributeurs.This device, which is well suited for some dispensers, may 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).So, in particular, when the same pump body must be fixed on container necks of different diameters, the device of document FR-2 719 292 does not not adapt because the outside diameter of the pump body should approximately match the inside diameter of the neck of the container. On the other hand, although this device allows compensate for manufacturing tolerances as well of the collar container than from the pump body, this compensation is limited due to the materials used for the body of the container (usually 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.Document FR-2 699 433 discloses a device for mounting intended to be easily mounted and dismountable from similar to a tapered plug. These measures has a rigid ring attached to the pump body and a or more sockets made of flexible material to adapt to necks of different diameters. Because the device must be easily removable, it does not allow secure fixing and guarantee perfect seal.

Un dispositif ayant les caractéristiques du préambule de la revendication 1 est connu du document DE-C-804 839.A device having the characteristics of the preamble of claim 1 is known from the document DE-C-804 839.

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.The object of the present invention is to provide a fastening device that overcomes the disadvantages above, while providing the same benefits, to know a cost saving for manufacturing and mounting of the product dispenser. This limitation of costs is particularly attractive when the distributor is a sample, such as a sample of perfume, 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 a such fixing device which allows 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 a such fastening device which is perfectly safe and waterproof. In particular, the fixing device must not not be easily removable.

Pour atteindre ces buts, la présente invention propose un dispositif de fixation selon la revendication 1. To achieve these goals, the present invention provides a fixing device according to claim 1.

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.Preferably, the fixing element is a ferrule whose outside diameter corresponds approximately to the diameter inside the neck of the container and whose diameter interior is, before fitting of the distribution, less than the outside diameter of the body the distribution body.

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 the top of the container neck, said flange retaining the fastening element during the fitting of the member of distribution.

Avantageusement, 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.Advantageously, said gripping means comprise a or more bulges of material which, before fitting of the dispensing member protrude towards the interior of said fastener, and which, when the fitting of said distribution member is forced under the container neck by the body of the distribution.

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 reduced diameter lower part which has little or no effect on said gripping means so that the interaction between the distributor and the said gripping means takes place only at the end of 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 déformable.According to a first embodiment, said means grip are made in the form of legs comprising each at their lower end a bulge of deformable material.

Selon un second mode de réalisation, lesdits moyens de prise sont réalisés sous la forme d'un renflement annulaire de matière déformable prévu à l'extrémité inférieure de l'élément de fixation.According to a second embodiment, said means for taken are made in the form of a bulge annular deformable material provided at the lower end of the fixing 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.Advantageously, the body of the dispensing member has 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 portion said gripping means being received in said groove for fix the distribution member with respect to said distribution member fixation.

Avantageusement, l'élément de fixation est réalisé en un matériau souple déformable tel que du polyéthylène ou un thermoplastique élastomère.Advantageously, the fixing element is produced in a deformable flexible material such as polyethylene or a thermoplastic elastomer.

En référence aux figures, l'invention concerne un dispositif de fixation d'un organe de distribution 10, tel qu'une pompe comportant un corps 11, dans le col 2 d'un récipient 1. Ce dispositif de fixation comporte un unique élément de fixation 20 réalisé en matériau déformable, disposé dans le col 2 du récipient 1 entre ledit col 2 du récipient et ledit corps de pompe 11.With reference to the figures, the invention relates to a fixing device for a dispensing member 10, such that a pump comprising a body 11, in the neck 2 of a container 1. This device fixing comprises a single fixing element 20 produced of deformable material, placed in the neck 2 of the container 1 between said neck 2 of the container and said pump body 11.

Ledit élément de fixation 20 est, de préférence réalisé en un matériau souple et déformable tel que du polyéthylène ou un thermoplastique élastomère.Said fastening element 20 is preferably made in a flexible and deformable material such as polyethylene or an elastomeric thermoplastic.

Cet élément de fixation 20 comporte, avant le montage, un diamètre extérieur correspondant environ au diamètre intérieur du col 2 du récipient, et un diamètre intérieur légèrement inférieur au diamètre extérieur du corps de pompe 11.This fastening element 20 comprises, before mounting, an outside diameter corresponding approximately to the diameter inside of container neck 2, and an inside diameter slightly smaller than the outside diameter of the pump body 11.

À l'état monté du dispositif de fixation, ledit élément de fixation 20 est déformé et/ou comprimé par l'emmanchement du corps de pompe 11 dans le col 2 du récipient, de sorte qu'il exerce une force radiale à la fois sur ledit corps de pompe 11 et sur ledit col 2 du récipient, ladite force radiale assurant la fixation étanche de la pompe dans le récipient.In the assembled state of the fixing, said fixing element 20 is deformed and / or compressed by fitting the pump body 11 into the neck 2 of the container, so that it exerts a radial force both on said pump body 11 and on said neck 2 of the container, said radial force ensuring tight fixing from the pump into the container.

Sur les figures 1 et 2, il est représenté une première variante d'un dispositif de fixation où s'applique l'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 Figures 1 and 2, there is shown a first variant of a fixing device where the invention applies. In this variant, the fixing element 20 is produced in the form of a cylindrical shell, which comes to adapt on and in the cylindrical neck 2 of a container 1, usually glass. This cylindrical shell 20 comprises advantageously a radial flange 21 at its end upper, that is to say its end disposed at the level of the top 3 of neck 2 of container 1. This ferrule 20 in the container covers part or all of the neck height 2.

Le corps de pompe 11 peut comporter une partie inférieure de diamètre réduit 11a 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 part lower diameter 11a which does not cooperate with said fastening element 20 during fitting. So, 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 largest diameter part of the body pump 11, i.e. for only part of the fitting. This deformation and / or compression creates a radial force exerted on the inner wall of the neck of the container and on the pump body. When the attachment is in the assembled state, as shown in the Figure 2, the pump 10 is held in place by said radial force exerted by the ferrule 20. The radial flange 21 useful for holding the ferrule 20 in place on the container neck when fitting the pump body.

En référence à la figure 3, il est représenté une autre variante d'un dispositif de fixation où s'applique 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 l'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.Referring to Figure 3, there is shown another variant of a fixing device where the invention applies. In this variant, the inner surface of the neck 2 of the container 1 is not cylindrical but frustoconical and the element of fastener 20 has a corresponding shape so that a flange radial as described in the embodiment shown in Figures 1 and 2, is not necessary here. Indeed, due to the frustoconical shape of the inside of the neck 2 of the container, the fastening element 20 is held automatically in place in col 2 when 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. Cette rainure 51 peut être réalisée dans le corps de pompe 11 (fig. 1 et 2) ou dans l'élément de fixation 50 (fig. 3).Advantageously, the pump body 11 may include a vent hole 50. This vent hole 50 can be arranged in the upper part of the pump body 11 and be connected to the container by a groove 51 or any other equivalent means. This groove 51 can be produced in the pump body 11 (fig. 1 and 2) or in the fixing element 50 (fig. 3).

Un mode de réalisation selon l'invention 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.An embodiment according to the invention is shown in Figures 4 to 9. In this embodiment, the element of fixing 20 has at its lower end means socket 25 adapted to fix the fixing element 20, to the assembled state of the device, under the neck 2 inside the container 1. As in the example shown with reference in Figures 1 and 2, the example shown in Figures 4 and 5, has a cylindrical ferrule 20 which fits in a neck 2 of also cylindrical container. Of course, this embodiment of FIGS. 4 and 5 also adapts in the embodiment of Figure 3, where the inside of the neck of the container is frustoconical.

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.As shown in Figures 4 and 5, the means of grip 25 have one or more bulges of material which, before fitting of the distribution member, that is to say from the pump, protrude inward from the fastening 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 déformable, soit sous la forme d'un renflement annulaire en matière déformable prévu à l'extrémité inférieure de l'élément de fixation 20. Avantageusement, le corps de pompe 11 comporte une partie inférieure de diamètre réduit 11a 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 under the shape of legs each having at its end lower a bulge of deformable material, either under the form of an annular bulge made of deformable material at the lower end of the fixing element 20. Advantageously, the pump body 11 comprises a part lower diameter reduced 11a which does not cooperate or little with said means of grip 25. Thus, the displacement of material under the neck 2, that is to say the fixing of the ferrule 20 under the said neck, occurs at the end of the fitting of the body pump 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 FIGS. 4 and 5. In this variant, the neck 2 has a peripheral rib 5 intended to allow embedding 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 l'extérieur à l'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 part frustoconical 6 flaring outwards at the end upper part of the inner surface of the neck 2. This part frustoconical 6 cooperates with the corresponding part of the fixing member 20 to ensure total tightness after fitting of the pump body 11. Indeed, by the fitting, the fixing member 20 is pulled towards inside the neck by the pump body. It is therefore created a strong seal at the top 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 selon l'invention. 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 according to the invention. 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, part of the bulges of material enters this groove 15, for example by creep, for securing the pump body relative to the member fixing 20. Thus, it is almost impossible to dismantle the pump while assembly is easier.

Le dispositif de fixation de la présente invention présente les avantages suivants :

  • 1- l'utilisation d'un élément de fixation 20 en matériau souple déformable 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.
  • 2- l'emmanchement à force du corps de pompe 11 à l'intérieur de l'élément de fixation déformable 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 l'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 11a du corps de pompe.
  • 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 l'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.
    • The fixing device of the present invention has the following advantages:
  • 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- 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 the fixing element of the pump body and the neck of the container. 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 FIGS. 6 to 9, This very strong seal at the level of the upper end of the neck of the container makes it possible to provide a 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 made 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- the presence of the gripping means, or bulge of material 25, at the lower end of the fastening element 20, allows the assembled state of the device to fix the ferrule irremovably 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.
