Description

La présente invention a trait à un dispositif et à un procédé de fixation d'un organe de distribution, tel qu'une pompe ou une valve, sur un col d'un récipient contenant du produit à distribuer.The present invention relates to a device and a method for fixing a dispensing member, such as a pump or a valve, to a neck of a container containing product to be dispensed.

La fixation d'un organe de distribution sur un col de récipient au moyen d'une bague est connue dans l'état de la technique, et permet notamment d'éviter un sertissage, facilitant le montage du dispositif.The fixing of a dispensing member to a container neck by means of a ring is known in the state of the art, and in particular makes it possible to avoid crimping, facilitating the mounting of the device.

Selon des techniques connues (voir brevet américain n°. 2 723 773, E. Greene 1955), une bague de fixation du type dit à encliquetage est disposée sur le corps d'un organe de distribution et est encliquetée sur le col du récipient, généralement au moyen de pattes d'encliquetage prévues à cet effet. Une frette est ensuite emmanchée autour de ladite bague pour maintenir celle-ci solidement sur le col du récipient.According to known techniques (see US Patent No. 2,723,773, E. Greene 1955), a fixing ring of the so-called snap-on type is disposed on the body of a dispensing member and is snapped onto the neck of the container, generally by means of latching tabs provided for this purpose. A hoop is then fitted around said ring to hold it securely on the container neck.

Pour obtenir une opération de montage simple et peu coûteuse, il faut que I'encliquetage de la bague et l'emmanchement de la frette se fassent mécaniquement sur une seule et même unité de montage. Ainsi, en exerçant une force suffisante sur la frette, on obtient l'encliquetage de la bague sur le col du récipient, et l'emmanchement de la frette sur la bague.To obtain a simple and inexpensive mounting operation, it is necessary that the ring snap-fitting and the fitting of the hoop be done mechanically on a single mounting unit. Thus, by exerting sufficient force on the hoop, one obtains the snap-fastening of the ring on the neck of the container, and the fitting of the hoop on the ring.

Les dispositifs actuels présentent certains inconvénients. Ainsi, lorsque la force exercée sur la frette n'est pas parfaitement répartie sur sa périphérie, il existe le risque que lors de l'emmanchement de ladite frette, celle-ci soit forcée hors de sa position verticale et vienne s'emmancher de travers sur la bague de fixation, empêchant un montage correct de l'ensemble.Current devices have certain drawbacks. Thus, when the force exerted on the hoop is not perfectly distributed over its periphery, there is the risk that during the fitting of said hoop, it will be forced out of its vertical position and come to be angled on the fixing ring, preventing correct assembly of the assembly.

La présente invention a pour but d'éviter cet inconvénient en fournissant une bague de fixation assurant un emmanchement effectif et sûr de ladite frette.The present invention aims to avoid this drawback by providing a fixing ring ensuring effective and secure fitting of said hoop.

Un objet de l'invention est donc un bague de fixation d'un organe de distribution sur un col d'un récipient contenant du produit à distribuer, ladite bague de fixation étant annulaire et comprenant une partie inférieure et une partie supérieure, la partie inférieure comportant des moyens de fixation sur ledit col et la partie supérieure comportant une ouverture pour l'organe de distribution et des moyens pour maintenir fixement ledit organe sur ledit col, dans laquelle ladite partie supérieure comporte en outre au moins un élément de paroi de guidage s'étendant verticalement dans la direction de l'axe longitudinal de l'organe de distribution sur la périphérie de ladite bague de fixation sensiblement en prolongement desdits moyens de fixation de ladite partie inférieure.An object of the invention is therefore a fixing ring for a dispensing member on a neck of a container containing product to be dispensed, said fixing ring being annular and comprising a lower part and an upper part, the lower part comprising fixing means on said neck and the upper part comprising an opening for the dispensing member and means for fixedly holding said member on said neck, in which said upper part further comprises at least one guide wall element s 'extending vertically in the direction of the longitudinal axis of the dispensing member on the periphery of said fixing ring substantially in extension of said fixing means of said lower part.

Selon un mode de réalisation préféré de la bague, lesdits moyens de fixation sont des moyens d'encliquetage, avantageusement réalisés sous forme de pattes.According to a preferred embodiment of the ring, said fixing means are latching means, advantageously made in the form of lugs.

Avantageusement, lesdits éléments de parois de guidage forment une couronne annulaire de guidage continue.Advantageously, said guide wall elements form an annular ring for continuous guide.

Une bague de fixation réalisée selon l'invention présente en outre l'avantage de permettre un prémontage de la frette sur la bague de fixation. Ainsi, la frette est disposée sur ladite bague autour desdits éléments de paroi de guidage avant d'être livrée au client. Celui-ci n'a plus alors qu'à remplir le récipient avec le produit de son choix et disposer l'ensemble formé de l'organe de distribution, la bague de fixation et la frette dans l'unité de montage.A fixing ring produced according to the invention also has the advantage of allowing pre-assembly of the hoop on the fixing ring. Thus, the hoop is arranged on said ring around said guide wall elements before being delivered to the customer. The latter then only has to fill the container with the product of its choice and place the assembly formed by the dispensing member, the fixing ring and the hoop in the mounting unit.

Les éléments de parois de guidage empêchent efficacement une éventuelle séparation de la frette et de la bague de fixation lors de la livraison, en raison des vibrations du transport, et assure un positionnement correct de ladite frette en vue de son emmanchement.The guide wall elements effectively prevent possible separation of the hoop and the fixing ring during delivery, due to transport vibrations, and ensures correct positioning of said hoop with a view to its fitting.

Avantageusement, les éléments de parois de guidage ont donc un diamètre extérieur environ égal au diamètre intérieur de la frette, permettant une mise en place de ladite frette par coulissement avec frottement, ledit frottement empêchant une séparation trop aisée.Advantageously, the guide wall elements therefore have an outside diameter approximately equal to the inside diameter of the hoop, allowing said hoop to be put in place by sliding with friction, said friction preventing separation that is too easy.

L'invention a donc également pour objet un dispositif de fixation d'un organe de distribution sur un col d'un récipient contenant du produit à distribuer, comportant une bague de fixation annulaire munie de moyens d'encliquetage destinés à s'encliqueter sur ledit col du récipient et une frette annulaire dont le diamètre intérieur est sensiblement égal au diamètre extérieur de la bague de fixation et qui vient s'emmancher à force sur ladite bague de fixation pour empêcher l'écartement desdits moyens d'encliquetage, dans lequel ladite bague de fixation comprend une partie inférieure et une partie supérieure, la partie inférieure comportant lesdits moyens d'encliquetage sur ledit col et la partie supérieure comportant une ouverture pour l'organe de distribution et des moyens pour le maintenir fixement sur ledit col, ladite partie supérieure comportant en outre au moins un élément de paroi de guidage s'étendant verticalement dans la direction de l'axe longitudinal de l'organe de distribution sur la périphérie de ladite bague de fixation sensiblement en prolongement desdits moyens d'encliquetage de ladite partie inférieure.The invention therefore also relates to a device for fixing a dispensing member to a neck of a container containing product to be dispensed, comprising an annular fixing ring provided with latching means intended to snap onto said neck of the container and an annular hoop whose internal diameter is substantially equal to the external diameter of the fixing ring and which is force fitted onto said fixing ring to prevent the spacing of said latching means, in which said ring of fixing comprises a lower part and an upper part, the lower part comprising said latching means on said neck and the upper part comprising an opening for the dispensing member and means for holding it fixedly on said neck, said upper part further comprising at least one guide wall element extending vertically in the direction of the longitudinal axis of the dispensing member on the periphery of said fixing ring substantially in extension of said latching means of said lower part.

Pour obtenir un montage effectif de la bague de fixation et de la frette sur une même unité de montage, il est indispensable que la fixation de la bague sur le col du récipient soit réalisée avant que la frette ne soit emmanchée sur ladite bague.To obtain an effective mounting of the fixing ring and the hoop on the same mounting unit, it is essential that the fixing of the ring on the neck of the container is carried out before the hoop is fitted on said ring.

Généralement, ce problème est résolu en prévoyant un frottement entre la bague et la frette supérieur à la résistance à l'encliquetage de la bague sur le col du récipient.Generally, this problem is resolved by providing friction between the ring and the hoop greater than the snap resistance of the ring on the neck of the container.

En exerçant une force suffisante sur la frette, on obtient donc d'abord l'encliquetage de la bague sur le col du récipient, puis l'emmanchement de la frette sur la bague. Cette technique présente l'inconvénient que les dimensions relatives de la bague et de la frette doivent être parfaitement définies pour fournir toujours le même frottement entre elles.By exerting sufficient force on the hoop, one thus obtains first the snap-fastening of the ring on the neck of the container, then the fitting of the hoop on the ring. This technique has the disadvantage that the relative dimensions of the ring and the hoop must be perfectly defined to always provide the same friction between them.

Lorsque, en raison de leur fabrication, les dimensions varient légèrement, le montage ne peut plus s'effectuer correctement. Il est en effet indispensable que l'encliquetage de la bague se fasse avant l'emmanchement de la frette, ce qui n'est pas réalisé si la résistance à l'encliquetage devient trop forte ou si le frottement entre la bague et la frette, est trop faible.When, due to their manufacture, the dimensions vary slightly, assembly can no longer be carried out correctly. It is indeed essential that the locking of the ring is done before the fitting of the hoop, which is not achieved if the resistance to the latching becomes too strong or if the friction between the ring and the hoop, is too weak.

Selon un système connu, on prévoit sur la circonférence externe de la bague à encliquetage, un ou plusieurs ergots saillants sur lesquels vient s'appuyer la frette et au moyen desquels celle-ci encliquette d'abord la bague sur le récipient avant de casser ou déformer lesdits ergots sous l'effet d'une pression plus forte, pour venir s'emmancher autour de ladite bague. Le problème des tolérances de dimensions est ainsi résolu mais de telles bagues peuvent être difficiles à mouler et ainsi augmenter le coût du dispositif.According to a known system, there is provided on the outer circumference of the snap ring, one or more projecting lugs on which the hoop rests and by means of which the latter first snaps the ring onto the container before breaking or deforming said lugs under the effect of greater pressure, so as to be fitted around said ring. The problem of dimensional tolerances is thus resolved, but such rings can be difficult to mold and thus increase the cost of the device.

La présente invention a pour but d'éviter ces inconvénients en fournissant une bague d'encliquetage et une frette faciles à mouler, pouvant être assemblées sur une même unité de montage et assurant un montage effectif indépendamment des tolérances de dimensions, ce qui permet de réduire sensiblement les coûts de fabrication du distributeur de produit.The object of the present invention is to avoid these drawbacks by providing a snap ring and a hoop which are easy to mold, which can be assembled on the same mounting unit and ensuring effective mounting regardless of the dimensional tolerances, which makes it possible to reduce significantly the manufacturing costs of the product distributor.

La présente invention a donc pour objet un dispositif de fixation d'un organe de distribution sur un col d'un récipient contenant du produit à distribuer, comportant une bague de fixation annulaire munie de moyens d'encliquetage destinés à s'encliqueter sur ledit col du récipient et une frette annulaire ayant au moins une partie dont le diamètre intérieur est sensiblement égal au diamètre extérieur de la bague de fixation et qui vient s'emmancher à force sur ladite bague de fixation pour empêcher l'écartement desdits moyens d'encliquetage, ladite bague de fixation comprenant une partie inférieure et une partie supérieure, la partie inférieure comportant lesdits moyens d'encliquetage sur ledit col et la partie supérieure comportant une ouverture pour l'organe de distribution et des moyens pour le maintenir fixement sur ledit col, ladite partie supérieure comportant en outre au moins un élément de paroi de guidage s'étendant verticalement dans la direction de l'axe longitudinal de l'organe de distribution sur la périphérie de ladite bague de fixation sensiblement en prolongement desdits moyens d'encliquetage de ladite partie inférieure, dans lequel ladite frette comporte sur la face interne de sa paroi latérale au moins un relief s'étendant verticalement sur au moins une partie de la hauteur de ladite paroi latérale, le diamètre intérieur de ladite frette au niveau dudit au moins un relief étant légèrement inférieur au diamètre extérieur de ladite bague de fixation. Avantageusement, ledit au moins un relief est un godron ou une nervure.The present invention therefore relates to a device for fixing a dispensing member to a neck of a container containing the product to be dispensed, comprising an annular fixing ring provided with latching means intended to snap onto said neck of the container and an annular hoop having at least one part whose internal diameter is substantially equal to the external diameter of the fixing ring and which is force fitted onto said fixing ring to prevent the spacing of said latching means, said fixing ring comprising a lower part and an upper part, the lower part comprising said latching means on said neck and the upper part comprising an opening for the dispensing member and means for holding it fixedly on said neck, said upper part further comprising at least one guide wall element extending vertically in the direction of the axis longitudinal of the dispensing member on the periphery of said fixing ring substantially as an extension of said latching means of said lower part, in which said hoop has on the internal face of its side wall at least one relief extending vertically over at least part of the height of said side wall, the inside diameter of said hoop at said at least one relief being slightly less than the outside diameter of said fixing ring. Advantageously, said at least one relief is a gadroon or a rib.

Ainsi, la frette peut être préengagée sur la paroi de guidage de la bague de fixation pour la livraison, ledit au moins un relief reposant avec son extrémité inférieure sur l'extrémité supérieure de la paroi de guidage, de sorte que lors du montage, ledit relief pousse sur ladite paroi de guidage de la bague, et l'ensemble bague plus frette est d'abord encliqueté sur le col du récipient, avant que la frette ne vienne s'emmancher sur ladite bague.Thus, the hoop can be pre-engaged on the guide wall of the fixing ring for delivery, said at least one relief resting with its lower end on the upper end of the guide wall, so that during mounting, said relief pushes on said guide wall of the ring, and the ring assembly plus hoop is first snapped onto the neck of the container, before the fret does not come to be fitted on said ring.

Avantageusement, ladite frette comporte une pluralité de reliefs répartis régulièrement autour de la face interne de la paroi latérale de ladite frette.Advantageously, said hoop comprises a plurality of reliefs distributed regularly around the internal face of the side wall of said hoop.

Eventuellement, ledit relief peut être constitué d'un épaulement annulaire s'étendant horizontalement sur toute la circonférence de la frette.Optionally, said relief may consist of an annular shoulder extending horizontally over the entire circumference of the hoop.

De préférence, ladite frette est réalisée en un matériau plus dur que celui de la bague de fixation. Avantageusement, ladite frette est métallique et ladite bague de fixation est en matière plastique.Preferably, said hoop is made of a harder material than that of the fixing ring. Advantageously, said hoop is metallic and said fixing ring is made of plastic.

Avantageusement, ledit au moins un relief s'étend verticalement à partir de l'extrémité supérieure de ladite frette jusqu'à un point situé au-delà de la moitié de la hauteur de ladite frette.Advantageously, said at least one relief extends vertically from the upper end of said hoop to a point located beyond half the height of said hoop.

Selon un autre mode de réalisation de l'invention, il est fourni un dispositif de fixation d'un organe de distribution sur un col d'un récipient contenant du produit à distribuer, comportant une bague de fixation annulaire munie de moyens d'encliquetage destinés à s'encliqueter sur ledit col du récipient et une frette annulaire ayant au moins une partie dont le diamètre intérieur est sensiblement égal au diamètre extérieur de la bague de fixation et qui vient s'emmancher à force sur ladite bague de fixation pour empêcher l'écartement desdits moyens d'encliquetage, ladite bague de fixation comprenant une partie inférieure et une partie supérieure, la partie inférieure comportant lesdits moyens d'encliquetage sur ledit col et la partie supérieure comportant une ouverture pour l'organe de distribution et des moyens pour le maintenir fixement sur ledit col, ladite partie supérieure comportant en outre au moins un élément de paroi de guidage s'étendant verticalement dans la direction de l'axe longitudinal de l'organe de distribution sur la périphérie de ladite bague de fixation sensiblement en prolongement desdits moyens d'encliquetage de ladite partie inférieure, dans lequel ladite frette comporte sur la face interne de sa paroi latérale au moins un relief s'étendant de manière oblique sur au moins une partie de la hauteur de ladite paroi latérale, le diamètre intérieur de ladite frette au niveau dudit au moins un relief étant légèrement intérieur au diamètre extérieur de ladite bague de fixation. Avantageusement, ledit au moins un relief est réalisé sous la forme d'un godron ou d'une nervure. Cette mise en oeuvre de la frette permet avantageusement une séparation par dévissage de la frette, généralement métallique, de la bague de fixation, généralement en matière plastique. Ceci présente notamment un grand intérêt concernant le recyclage sélectif des éléments constitutifs du distributeur de produit.According to another embodiment of the invention, there is provided a device for fixing a dispensing member to a neck of a container containing product to be dispensed, comprising an annular fixing ring provided with latching means intended to snap onto said neck of the container and an annular hoop having at least one part, the inside diameter of which is substantially equal to the outside diameter of the fixing ring and which is force fitted onto said fixing ring to prevent spacing of said latching means, said fixing ring comprising a lower part and an upper part, the lower part comprising said latching means on said neck and the upper part comprising an opening for the dispensing member and means for the fixedly hold on said neck, said upper part further comprising at least one guide wall element extending vertically from ns the direction of the longitudinal axis of the dispensing member on the periphery of said fixing ring substantially in extension of said latching means of said lower part, in which said hoop has on the internal face of its lateral wall at least a relief extending obliquely over at least part of the height of said side wall, the inside diameter of said hoop at said at least one relief being slightly inside the outside diameter of said fixing ring. Advantageously, said at least one relief is produced in the form of a gadroon or a rib. This implementation of the hoop advantageously allows separation by unscrewing the hoop, generally metallic, of the fixing ring, generally made of plastic. This is particularly of great interest concerning the selective recycling of the constituent elements of the product distributor.

Selon un aspect de l'invention, il est fourni une bague de fixation annulaire destinée à fixer un organe de distribution sur le col d'un récipient contenant du produit à distribuer. Deux variantes possibles d'une telle bague de fixation sont représentées sur les figures 1 et 2.According to one aspect of the invention, there is provided an annular fixing ring intended to fix a dispensing member on the neck of a container containing product to be dispensed. Two possible variants of such a fixing ring are shown in FIGS. 1 and 2.

En référence à la figure 1, la bague de fixation 10 comporte une partie inférieure destinée à coopérer avec la col du récipient et une partie supérieure, destinée à coopérer avec l'organe de distribution. La partie inférieure comporte des moyens de fixation 12, 13 sur ledit col qui peuvent être des moyens d'encliquetage. Avantageusement, ces moyens d'encliquetage sont des pattes d'encliquetage 12, de préférence réparties autour de la circonférence de la bague 10, et s'étendant, dans le sens de l'axe central de la bague 10, vers le bas sur les figures 1 et 2. Chacune de ces pattes 12 comporte avantageusement à son extrémité inférieure un ergot d'encliquetage 13 faisant saillie de la surface intérieure de la bague et pouvant s'écarter légèrement sous l'effet d'une force suffisante pour passer par dessus puis venir s'encliqueter sous le col du récipient.With reference to FIG. 1, the fixing ring 10 comprises a lower part intended to cooperate with the neck of the container and an upper part, intended to cooperate with the dispensing member. The lower part includes fixing means 12, 13 on said neck which can be latching means. Advantageously, these latching means are latching lugs 12, preferably distributed around the circumference of the ring 10, and extending, in the direction of the central axis of the ring 10, downward on the Figures 1 and 2. Each of these tabs 12 advantageously comprises at its lower end a latching lug 13 projecting from the inner surface of the ring and being able to deviate slightly under the effect of sufficient force to pass over it then snap under the neck of the container.

La partie inférieure de la bague est reliée à la partie supérieure au niveau d'un plat 11 qui s'étend vers l'intérieur de la bague radialement par rapport à l'axe central de la bague, environ perpendiculairement auxdites pattes 12. Ledit plat 11 vient reposer soit directement sur la surface supérieure du col du récipient, ou sur un joint d'étanchéité qui peut être prévu à cet endroit, soit sur une surface complémentaire de l'organe de distribution pour assujettir celui-ci au col du récipient.The lower part of the ring is connected to the upper part at the level of a plate 11 which extends towards the inside of the ring radially with respect to the central axis of the ring, approximately perpendicular to said legs 12. Said flat 11 comes to rest either directly on the upper surface of the neck of the container, or on a seal which can be provided at this location, or on a complementary surface of the dispensing member to secure the latter to the neck of the container.

Dans le premier cas, comme représenté sur la figure 1, le plat 11 peut se prolonger radialement à l'intérieur de la bague par une tourette 15 permettant d'assujettir fixement une partie de l'organe de distribution.In the first case, as shown in FIG. 1, the dish 11 can extend radially inside the ring by a turn 15 making it possible to fix part of the dispensing member fixedly.

Selon la variante de réalisation, c'est le plat 11 ou la tourette 15 qui définit une ouverture centrale 16 pour le passage de l'organe de distribution.According to the alternative embodiment, it is the dish 11 or the spinner 15 which defines a central opening 16 for the passage of the dispensing member.

Selon l'invention, la partie supérieure de la bague d'encliquetage 10 comporte en outre un ou plusieurs éléments de paroi de guidage 14 s'étendant verticalement dans le sens de l'axe central de la bague vers le haut en prolongement des pattes d'encliquetage 12. Avantageusement, ces éléments de paroi de guidage peuvent former une couronne annulaire de guidage continue 14.According to the invention, the upper part of the snap ring 10 further comprises one or more guide wall elements 14 extending vertically in the direction of the central axis of the ring upwards in extension of the tabs d Advantageously, these guide wall elements can form an annular ring for continuous guide 14.

Selon un autre aspect de la présente invention, il est fourni un dispositif de fixation d'un organe de distribution sur le col d'un récipient contenant du produit à distribuer, ledit dispositif comportant ladite bague de fixation 10 décrite précédemment ainsi qu'une frette venant s'emmancher autour des pattes 12 de ladite bague 10 pour empêcher l'écartement desdites pattes 12, et ainsi fixer solidement ladite bague 10, et donc l'organe de distribution, sur le col du récipient.According to another aspect of the present invention, there is provided a device for fixing a dispensing member to the neck of a container containing product to be dispensed, said device comprising said fixing ring 10 described above as well as a hoop coming to fit around the legs 12 of said ring 10 to prevent the spacing of said legs 12, and thus securely fix said ring 10, and therefore the dispensing member, on the neck of the container.

En référence à la figure 3, il est représenté partiellement un distributeur de produits comportant un récipient 1 muni d'un col 2 et un organe de distribution 3 comprenant un corps 4 prolongé par une tête de distribution 5. Le récipient est généralement réalisé en verre ou un matériau plastique et son col est cylindrique. L'organe de distribution 3 est généralement une pompe ou une valve selon la nature du produit à distribuer qui peut être de consistance quelconque Pour fixer l'organe de distribution sur le col 2 du récipient 1, on utilise une bague de fixation annulaire 10 telle que décrite précédemment en référence à la figure 1 qui vient se placer sur une partie supérieure 6 du corps 4 de l'organe de distribution 3. Bien entendu, on pourrait également utiliser la bague représentée sur la figure 2 ou toute autre bague similaire L'organe de distribution 3 est maintenu sur ledit col 2 au moyen dudit plat 11 et de ladite tourette 15 comportant une ouverture 16 à travers laquelle passe ladite tête de distribution 5. Eventuellement, on prévoit un joint d'étanchéité 7 entre la surface supérieure du col 2 du récipient et le plat 11 de la bague de fixation 10.Referring to Figure 3, there is partially shown a product dispenser comprising a container 1 provided with a neck 2 and a dispensing member 3 comprising a body 4 extended by a dispensing head 5. The container is generally made of glass or a plastic material and its neck is cylindrical. The dispensing member 3 is generally a pump or a valve depending on the nature of the product to be dispensed which can be of any consistency. To fix the dispensing member to the neck 2 of the container 1, an annular fixing ring 10 is used such that as described above with reference to Figure 1 which is placed on an upper part 6 of the body 4 of the dispensing member 3. Of course, one could also use the ring shown in Figure 2 or any other similar ring L ' dispensing member 3 is held on said neck 2 by means of said dish 11 and said spinner 15 having an opening 16 through which passes said dispensing head 5. Optionally, a seal 7 is provided between the upper surface of the neck 2 of the container and the dish 11 of the fixing ring 10.

Comme décrit ci-dessus, la bague de fixation ou d'encliquetage 10 comporte un ou plusieurs éléments de paroi de guidage 14 pouvant avantageusement être réalisés sous la forme d'une couronne annulaire de guidage 14.As described above, the fixing or snap ring 10 comprises one or more guide wall elements 14 which can advantageously be produced in the form of an annular guide ring 14.

Sur cette couronne annulaire 14 vient se placer une frette annulaire 20 destinée à être emmanchée à force sur ladite bague 10 pour empêcher l'écartement des pattes dencliquetage 12. Cette frette 20 comporte à son extrémité supérieure une ouverture 23 pour le passage d'un bouchon 30 venant se placer sur la tête 5 de l'organe de distribution 3.On this annular ring 14 is placed an annular hoop 20 intended to be force fitted on said ring 10 to prevent the spacing of the latching lugs 12. This hoop 20 has at its upper end an opening 23 for the passage of a plug 30 being placed on the head 5 of the dispensing member 3.

De préférence, le diamètre extérieur de la couronne de guidage 14, ou le cas échéant, des éléments de paroi de guidage, est sensiblement identique au diamètre intérieur de la paroi latérale de la frette 20. Ainsi, la frette 20 peut coulisser avec frottement sur ladite couronne de guidage 14 pour venir se mettre dans sa position de prémontage, dans laquelle l'ensemble est ensuite disposé dans l'unité de montage pour l'assemblage final.Preferably, the outside diameter of the guide ring 14, or where appropriate, of the guide wall elements, is substantially identical to the diameter inside the side wall of the hoop 20. Thus, the hoop 20 can slide with friction on said guide ring 14 to come into its pre-assembly position, in which the assembly is then placed in the mounting unit for final assembly.

Le frottement entre la couronne de guidage 14 et la frette 20 empêche une séparation de ces deux éléments lors de la livraison. De plus, la couronne de guidage 14 s'étendant sensiblement en prolongement des pattes d'encliquetage 12, un emmanchement parfaitement droit de la frette 20 autour desdites pattes d'encliquetage 12 est assuré.The friction between the guide ring 14 and the hoop 20 prevents separation of these two elements during delivery. In addition, the guide ring 14 extending substantially in extension of the latching lugs 12, a perfectly straight fitting of the hoop 20 around said latching lugs 12 is ensured.

Pour réaliser un montage et une fixation effectifs de l'organe de distribution 3 sur le col 2 du récipient 1, sur une seule unité de montage, l'emmanchement de la frette 20 ne doit pas se réaliser avant que les pattes 12 de la bague 10 se soient encliquetées sous ledit col 2.To achieve effective mounting and fixing of the dispensing member 3 on the neck 2 of the container 1, on a single mounting unit, the fitting of the hoop 20 must not be carried out before the tabs 12 of the ring 10 are snapped under said collar 2.

A cet effet, et selon un autre aspect de l'invention représenté sur les figures 4 à 12, la frette 20 comporte sur la face interne 21a de sa paroi latérale annulaire 21 au moins un relief 22, 24 s'étendant sur une partie de la hauteur de ladite paroi latérale 21. Le diamètre intérieur de la frette 20 au niveau dudit au moins un relief 22, 24 est légèrement inférieur au diamètre extérieur de la bague 10. Comme représenté sur les figures 11 et 12, ledit au moins un relief 22, 24 peut être mis en oeuvre sous la forme de nervures ou de godrons. Dans le premier cas, la surface extérieure 21 b de la frette 20 reste parfaitement cylindrique, ce qui peut constituer un avantage esthétique.To this end, and according to another aspect of the invention shown in FIGS. 4 to 12, the hoop 20 has on the internal face 21a of its annular side wall 21 at least one relief 22, 24 extending over part of the height of said side wall 21. The inside diameter of the hoop 20 at said at least one relief 22, 24 is slightly less than the outside diameter of the ring 10. As shown in FIGS. 11 and 12, said at least one relief 22, 24 can be implemented in the form of ribs or gadroons. In the first case, the outer surface 21b of the hoop 20 remains perfectly cylindrical, which can constitute an aesthetic advantage.

Dans un premier mode de réalisation de la frette représenté sur les figures 4a-c à 7, les reliefs 22 s'étendent verticalement sur la paroi latérale 21. De préférence, la frette 20 comporte une pluralité de ces reliefs 22 répartis régulièrement autour de la face interne 21a de ladite paroi latérale 21, comme visible sur les figures 5 et 6. Avantageusement, comme représenté sur la figure 5, ces reliefs 22 s'étendent à partir de l'extrémité supérieure de ladite frette 20 jusqu'à au moins la moitié de la hauteur de ladite frette 20 et sont tous identiques. Selon un mode de réalisation de l'invention, représenté sur la figure 7, ledit relief 22 est constitué d'un épaulement annulaire s'étendant horizontalement sur toute la circonférence de la frette 20.In a first embodiment of the hoop shown in FIGS. 4a-c to 7, the reliefs 22 extend vertically on the side wall 21. Preferably, the hoop 20 comprises a plurality of these reliefs 22 distributed regularly around the internal face 21a of said side wall 21, as visible in FIGS. 5 and 6. Advantageously, as shown in FIG. 5, these reliefs 22 extend from the upper end of said hoop 20 to at least the half the height of said hoop 20 and are all identical. According to one embodiment of the invention, shown in FIG. 7, said relief 22 consists of an annular shoulder extending horizontally over the entire circumference of the hoop 20.

Dans un second mode de réalisation de la frette représenté sur les figures 8a-b à 10, les reliefs 24 s'étendent de manière oblique sur la paroi latérale 21. Avantageusement, ledit au moins un relief oblique 24 a une forme allongée pour former un filetage interne sur la paroi latérale annulaire 21 de la frette 20. Cette mise en oeuvre est particulièrement intéressante lorsque la bague 10 est en plastique et la frette 20 en métal. En effet, la matière plastique de la bague épouse par fluage, après un laps de temps qui dépend de la dureté de ladite matière plastique, la forme dudit au moins un relief 24 de la frette 20.In a second embodiment of the hoop shown in Figures 8a-b to 10, the reliefs 24 extend obliquely on the side wall 21. Advantageously, said at least one oblique relief 24 has an elongated shape to form a internal thread on the annular side wall 21 of the hoop 20. This implementation is particularly advantageous when the ring 10 is made of plastic and the hoop 20 is made of metal. In fact, the plastic material of the ring follows by creep, after a period of time which depends on the hardness of said plastic material, the shape of said at least one relief 24 of the hoop 20.

Ledit relief oblique 24 formant un filetage interne sur la paroi latérale 21 de la frette 20, celle-ci peut donc facilement être retirée de ladite bague par simple dévissage lorsque le distributeur de produit n'est plus utilisé. Il est donc possible de séparer les éléments en plastique des éléments en métal en vue d'un recyclage sélectif.Said oblique relief 24 forming an internal thread on the side wall 21 of the hoop 20, the latter can therefore easily be removed from said ring by simple unscrewing when the product dispenser is no longer used. It is therefore possible to separate the plastic elements from the metal elements for selective recycling.

Dans une première variante représentée sur la figure 9, la face interne de la paroi latérale 21 de la frette 20 comporte un seul relief 24. Avantageusement, ce relief oblique s'étend environ sur un tour complet de la circonférence de la paroi latérale 21. Il est bien clair dans ce cas que la pente dudit relief 24 est relativement faible.In a first variant shown in FIG. 9, the internal face of the side wall 21 of the hoop 20 has a single relief 24. Advantageously, this oblique relief extends approximately over a complete revolution of the circumference of the side wall 21. It is very clear in this case that the slope of said relief 24 is relatively small.

Dans une seconde variante représentée sur la figure 10, la face interne de la paroi latérale annulaire de la frette est pourvue de plusieurs reliefs obliques 24 parallèles qui sont avantageusement répartis régulièrement autour de la circonférence de ladite paroi latérale.In a second variant shown in Figure 10, the inner face of the annular side wall of the hoop is provided with several oblique reliefs 24 parallel which are advantageously distributed regularly around the circumference of said side wall.

Le fonctionnement du dispositif de fixation va brièvement être décrit en référence aux figures 4a-c, incorporant la frette avec des reliefs verticaux, mais il est clair que le dispositif fonctionne de manière identique avec une frette ayant un ou plusieurs reliefs obliques.The operation of the fixing device will be briefly described with reference to FIGS. 4a-c, incorporating the hoop with vertical reliefs, but it is clear that the device works in the same way with a hoop having one or more oblique reliefs.

La bague de fixation 10 est enfilée autour de la tête 5 de l'organe de distribution 3 et vient se fixer par sa tourette 15 sur la partie supérieure 6 du corps de l'organe de distribution 3. La frette 20 est alors disposée autour du ou des éléments de parois de guidage 14 formant avantageusement une couronne annulaire de ladite bague de fixation 10 et vient buter, par l'intermédiaire des extrémités inférieures 22a des reliefs 22, sur l'extrémité supérieure de la couronne annulaire 14 de la bague de fixation 10. L'ensemble constitué de l'organe de distribution 3, de la bague 10 et de la frette 20 est ainsi dans sa position préengagée représentée sur la figure 4a, dans lequel il sera livré au client. Celui-ci n'a alors plus qu'à remplir le récipient avec le produit de son choix et de placer ledit récipient 1 et ledit ensemble 3, 10, 20 dans une unique unité de montage.The fixing ring 10 is threaded around the head 5 of the dispensing member 3 and is fixed by its turn 15 on the upper part 6 of the body of the dispensing member 3. The hoop 20 is then placed around the or elements of guide walls 14 advantageously forming an annular ring of said fixing ring 10 and abuts, via the lower ends 22a of reliefs 22, on the upper end of the annular ring 14 of the fixing ring 10. The assembly consisting of the dispensing member 3, the ring 10 and the hoop 20 is thus in its pre-engaged position shown in FIG. 4a, in which it will be delivered to the customer. The latter then only has to fill the container with the product of its choice and to place said container 1 and said assembly 3, 10, 20 in a single mounting unit.

Le corps 4 de l'organe de distribution 3 est ainsi introduit dans le col du récipient et les pattes d'encliquetage 12 viennent reposer sur le joint d'étanchéité 7 disposé sur la surface supérieure du col 2 du récipient 1. L'ensemble est ensuite disposé dans l'unité de montage où une première force de poussée F1 verticale est appliquée à la frette 20. Le diamètre intérieur de cette frette 20 au niveau des reliefs 22 étant inférieur au diamètre extérieur de la bague de fixation 10, ladite frette ne peut donc plus coulisser sur ladite bague. La force F1 est donc transmise par la frette 20 à la bague de fixation 10, dont les pattes d'encliquetage 12 s'écartent sous l'effet de ladite force F1, ce qui fait coulisser ladite bague sur le col du récipient jusqu'à ce que les pattes d'encliquetage 12 viennent s'encliqueter sous ledit col 2, comme visible sur la figure 4b. Le corps 4 de l'organe de distribution 3 est alors mis en place fixement à l'intérieur du récipient, I'étanchéité étant assurée par le joint annulaire 7.The body 4 of the dispensing member 3 is thus introduced into the neck of the container and the latching tabs 12 come to rest on the seal 7 disposed on the upper surface of the neck 2 of the container 1. The assembly is then disposed in the mounting unit where a first vertical pushing force F1 is applied to the hoop 20. The inside diameter of this hoop 20 at the reliefs 22 being less than the outside diameter of the fixing ring 10, said hoop does not can therefore no longer slide on said ring. The force F1 is therefore transmitted by the hoop 20 to the fixing ring 10, the latching tabs 12 of which move apart under the effect of said force F1, which causes said ring to slide on the neck of the container until that the latching tabs 12 snap under said neck 2, as visible in FIG. 4b. The body 4 of the organ of distribution 3 is then fixedly placed inside the container, the seal being ensured by the annular seal 7.

Une seconde force de poussée F2 verticale est ensuite appliquée à la frette 20. Cette seconde force F2 est supérieure à la première force F1 et est suffisante pour emmancher à force ladite frette 20 sur la bague de fixation 10 par l'intermédiaire des reliefs 22.A second vertical thrust force F2 is then applied to the hoop 20. This second force F2 is greater than the first force F1 and is sufficient to force fit said hoop 20 onto the fixing ring 10 via the reliefs 22.

Les pattes d'encliquetage 12 de la bague de fixation 10 sont alors maintenues dans leur position de verrouillage et ne peuvent plus s'écarter, ce qui assure la fixation définitive de l'organe de distribution 3 dans le récipient, comme visible sur la figure 4c.The latching tabs 12 of the fixing ring 10 are then held in their locking position and can no longer move away, which ensures the final fixing of the dispensing member 3 in the container, as visible in the figure 4c.

La différence requise entre les forces F1 et F2 dépend de l'épaisseur radiale des reliefs 22 de la frette 20. Une épaisseur radiale suffisante permet d'assurer un assemblage effectif, même si les pattes d'encliquetage 12 sont, pour des raisons de fabrication, un peu moins souples que prévu, ce qui augmente la résistance à l'encliquetage.The difference required between the forces F1 and F2 depends on the radial thickness of the reliefs 22 of the hoop 20. A sufficient radial thickness makes it possible to ensure effective assembly, even if the snap-on lugs 12 are, for manufacturing reasons , slightly less flexible than expected, which increases the snap resistance.

La frette 20 étant avantageusement métallique, l'emmanchement à force de celle-ci sur la bague de fixation 10, généralement en plastique, est possible malgré le diamètre intérieur inférieur de ladite frette 20, au niveau des reliefs 22, par rapport au diamètre extérieur de ladite bague 10, lesdits reliefs 22 venant s'incruster dans la couronne de guidage annulaire 14 de la bague de fixation 10.The hoop 20 being advantageously metallic, the press fitting thereof on the fixing ring 10, generally made of plastic, is possible despite the lower internal diameter of said hoop 20, at the reliefs 22, relative to the external diameter of said ring 10, said reliefs 22 being embedded in the annular guide ring 14 of the fixing ring 10.
