It may also be noted that the sealing is significantly improved with such a skirt, since the radial tightening at the level of the first zone 321 is very strong, and in any case much greater than a fixing by simple snap-fastening as in document US Pat.

Description

Distributeur de produit fluide Fluid dispenser
La présente invention concerne un distributeur de produit fluide comprenant un récipient, un organe de distribution tel qu'une pompe ou une valve et une bague de fixation pour fixer l'organe de distribution sur le récipient. De tels distributeurs sont fréquemment utilisés dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie pour distribuer des produits fluides par appui manuel à l'aide d'un doigt sur un poussoir.The present invention relates to a fluid dispenser comprising a container, a dispensing member such as a pump or a valve and a fixing ring for fixing the dispensing member to the container. Such dispensers are frequently used in the field of perfumery, cosmetics or even pharmacy to dispense fluid products by manual support using a finger on a pusher.
La présente invention s'intéresse plus particulièrement à un type de récipient formant une ouverture définissant une paroi interne qui forme une section d'ouverture rétrécie en dessous de laquelle la paroi s'évide au moins localement vers l'extérieur pour former une section inférieure d'ouverture évidée. Quant à la bague de fixation, celle-ci comprend des moyens de réception pour recevoir le corps de l'organe de distribution et une jupe de fixation destinée à être emmanchée en force dans ladite ouverture. La jupe comprend une paroi externe définissant une première zone venant se placer au niveau de la section d'ouverture rétrécie et une seconde zone venant se placer au niveau de la section d'ouverture évidée lorsque la jupe est emmanchée à fond dans l'ouverture du récipient. Un distributeur comportant une telle bague de fixation est connu du document US 3 937 366. Dans ce document, la paroi interne du col du récipient comprend une rainure périphérique dans laquelle vient s'encliqueter une nervure formée sur la paroi externe de la jupe. La partie de la jupe située juste au-dessus de la nervure présente un diamètre inférieur à celui de la nervure, même lorsque la jupe n'est pas encore emmanchée dans le col du récipient. On peut dire que le profil externe de la jupe est parfaitement complémentaire au profil interne du col du récipient. De même, la forme de la rainure dans la paroi interne du col est exactement complémentaire à la forme de la nervure de la jupe. Ainsi, il n'y a pas de contact radial serrant entre la jupe et la paroi interne du col, mais juste un encliquetage de la nervure dans la rainure du col. L'étanchéité entre la jupe et le col n'est ainsi que très difficilement assurée. II en est de même pour le système de fixation décrit dans le document FR-The present invention relates more particularly to a type of container forming an opening defining an internal wall which forms a narrowed opening section below which the wall is hollowed out at least locally outwards to form a lower section d opening. As for the fixing ring, this comprises receiving means for receiving the body of the dispensing member and a fixing skirt intended to be force fitted into said opening. The skirt comprises an external wall defining a first zone coming to be placed at the level of the narrowed opening section and a second zone coming to be placed at the level of the opening section hollowed out when the skirt is fitted fully into the opening of the container. A dispenser comprising such a fixing ring is known from document US 3,937,366. In this document, the internal wall of the container neck comprises a peripheral groove into which a rib formed on the external wall of the skirt is snapped. The part of the skirt situated just above the rib has a diameter smaller than that of the rib, even when the skirt is not yet fitted into the neck of the container. We can say that the external profile of the skirt is perfectly complementary to the internal profile of the container neck. Similarly, the shape of the groove in the inner wall of the neck is exactly complementary to the shape of the rib of the skirt. Thus, there is no tight radial contact between the skirt and the inner wall of the neck, but just a snap of the rib in the groove of the neck. The tightness between the skirt and the collar is thus only very difficult to ensure. It is the same for the fixing system described in the document FR-
2 792 295. Ce système utilise une bague sur laquelle est montée une pompe ou une valve. Cette bague coopère également avec la paroi interne d'un col de récipient qui présente une section d'ouverture rétrécie en dessous de laquelle s'étend une section d'ouverture évidée. La bague est également formée avec une jupe destinée à venir s'engager à l'intérieur du col. Cette jupe présente une saillie radiale externe destinée à venir se loger dans la section d'ouverture évidée qui se présente ici sous la forme d'un simple évidement périphérique formé à l'intérieur de la paroi interne du col. Il s'agit ici d'un système d'encliquetage qui consiste à engager la saillie externe de la jupe de la bague dans l'evidement interne du col. Au-dessus de la saillie externe, la jupe définit une section de diamètre inférieur qui vient se loger au niveau de la section d'ouverture rétrécie formée juste au-dessus de l'evidement interne du col. Cependant, il n'est pas visible sur les figures de ce document que le diamètre externe de la section de la jupe situé au niveau de la section d'ouverture rétrécie du col présente un diamètre inférieur à ce dernier. Ceci n'est pas non plus décrit dans le texte de ce document. D'ailleurs, dans le texte de ce document ainsi que dans les revendications, il est clairement défini que l'organe de fixation comprend des moyens d'encliquetage aptes à se loger dans ledit évidement de la paroi interne du col ; en l'occurrence, ces moyens d'encliquetage sont formés par la saillie externe dans le mode de réalisation de la figure 3. La présente invention cherche à remédier aux inconvénients de l'art antérieur en définissant une bague de fixation qui réalise à la fois une fixation solide et une parfaite étanchéité.2,792,295. This system uses a ring on which a pump or a valve. This ring also cooperates with the internal wall of a container neck which has a narrowed opening section below which extends a hollowed out opening section. The ring is also formed with a skirt intended to engage inside the neck. This skirt has an external radial projection intended to be housed in the recessed opening section which is here in the form of a simple peripheral recess formed inside the internal wall of the neck. This is a snap system which consists in engaging the external projection of the skirt of the ring in the internal recess of the neck. Above the external projection, the skirt defines a section of smaller diameter which is received at the level of the narrowed opening section formed just above the internal recess of the neck. However, it is not visible in the figures of this document that the outer diameter of the section of the skirt located at the narrowed opening section of the neck has a diameter less than the latter. This is also not described in the text of this document. Moreover, in the text of this document as well as in the claims, it is clearly defined that the fixing member comprises latching means capable of being housed in said recess of the internal wall of the neck; in this case, these latching means are formed by the external projection in the embodiment of Figure 3. The present invention seeks to overcome the drawbacks of the prior art by defining a fixing ring which achieves both a solid fixing and a perfect seal.
Pour atteindre ce but, la présente invention propose que la première zone de la jupe présente, avant emmanchage de la jupe dans l'ouverture, un diamètre externe supérieur au diamètre interne de la section d'ouverture rétrécie. Ceci n'est pas le cas dans le document US 3 937 366 dans lequel la première zone de la jupe a un diamètre strictement égal à celui du col au niveau de son ouverture. Avantageusement, la section d'ouverture rétrécie est sensiblement indéformable et la première zone est déformable sur la section d'ouverture rétrécie. En choisissant ainsi un diamètre de jupe supérieur à celui de la section d'ouverture rétrécie, on déforme la jupe par fluage de matière, de sorte que la section d'ouverture rétrécie mord dans la paroi externe de la jupe, assurant ainsi une fixation solide et une parfaite étanchéité. La déformation radiale de la première zone vers l'intérieur engendre un serrage radial puissant contre la section d'ouverture rétrécie de l'ouverture. Selon une autre caractéristique, la seconde zone présente un diamètre externe supérieur au diamètre interne de la section d'ouverture rétrécie et inférieur au diamètre interne maximal de la section d'ouverture évidée. La seconde zone, qui a été contrainte radialement vers l'intérieur lors du passage de la section d'ouverture rétrécie, peut ainsi se détendre librement par dilatation radiale vers l'extérieur au niveau de la section d'ouverture évidée. Du fait que la seconde zone n'est pas en contact de la paroi interne du col au niveau de la section d'ouverture évidée, ceci facilite le fluage de matière depuis la première zone vers la seconde zone du fait de l'interférence créée par la section d'ouverture rétrécie mordant dans la première zone. Selon un autre aspect de l'invention, la jupe est éloignée du corps par un espace intermédiaire. Ainsi, la déformation de la jupe ne peut en aucun cas engendrer une déformation du corps de l'organe de distribution.To achieve this object, the present invention proposes that the first zone of the skirt has, before fitting the skirt into the opening, an external diameter greater than the internal diameter of the narrowed opening section. This is not the case in document US 3,937,366 in which the first zone of the skirt has a diameter strictly equal to that of the neck at the level of its opening. Advantageously, the narrowed opening section is substantially non-deformable and the first zone is deformable on the narrowed opening section. By thus choosing a skirt diameter greater than that of the narrowed opening section, the skirt is deformed by material creep, so that the section narrowed opening bites into the outer wall of the skirt, thus ensuring a solid fixing and a perfect seal. The radial deformation of the first zone towards the inside generates a powerful radial clamping against the narrowed opening section of the opening. According to another characteristic, the second zone has an external diameter greater than the internal diameter of the narrowed opening section and less than the maximum internal diameter of the hollowed out opening section. The second zone, which has been forced radially inward during the passage of the narrowed opening section, can thus relax freely by radial expansion outwards at the level of the hollowed out opening section. Since the second zone is not in contact with the internal wall of the neck at the level of the recessed opening section, this facilitates the flow of material from the first zone towards the second zone due to the interference created by the narrowed opening section biting into the first area. According to another aspect of the invention, the skirt is spaced from the body by an intermediate space. Thus, the deformation of the skirt can in no case cause a deformation of the body of the dispensing member.
Avantageusement, la bague comprend une bride périphérique qui s'étend radialement vers l'extérieur à partir de l'extrémité supérieure de la jupe et qui est destinée à venir en contact de butée sur l'ouverture du récipient pour limiter la profondeur d'emmanchage de la jupe dans l'ouverture.Advantageously, the ring comprises a peripheral flange which extends radially outwards from the upper end of the skirt and which is intended to come into abutment contact on the opening of the container to limit the depth of fitting. of the skirt in the opening.
De préférence, la bride sert d'organe de transfert de poussée pour emmancher la jupe dans l'ouverture.Preferably, the flange serves as a thrust transfer member for fitting the skirt into the opening.
Selon un autre aspect de l'invention, la section d'ouverture rétrécie se raccorde vers le bas à la section d'ouverture évidée par une section de transition sensiblement tronconique ou évasée. Ainsi, la paroi externe de la jupe coopère après emmanchage de la jupe dans l'ouverture avec la section d'ouverture rétrécie et la section de transition pour améliorer la fixation et l'étanchéité.According to another aspect of the invention, the narrowed opening section is connected downwards to the opening section hollowed out by a substantially frustoconical or flared transition section. Thus, the outer wall of the skirt cooperates after fitting the skirt into the opening with the narrowed opening section and the transition section to improve the fixing and sealing.
En variante ou en complément, la section d'ouverture rétrécie se prolonge vers le haut avec une section d'attaque sensiblement tronconique ou évasée.As a variant or in addition, the narrowed opening section extends upwards with a substantially frustoconical or flared attack section.
Ainsi, la paroi externe de la jupe, après emmanchage de la jupe dans l'ouverture, peut coopérer avec la section d'ouverture rétrécie et la section d'attaque pour améliorer la fixation et l'étanchéité.Thus, the external wall of the skirt, after fitting the skirt into the opening, can cooperate with the narrowed opening section and the driving section to improve fixing and sealing.
Selon une forme de réalisation pratique, la paroi externe de la jupe, avant emmanchage, est cylindrique et présente un diamètre externe constant au niveau des première et seconde zones. Avantageusement, la jupe présente une extrémité inférieure libre chanfreinée pour faciliter son insertion dans l'ouverture du récipient.According to a practical embodiment, the external wall of the skirt, before fitting in, is cylindrical and has a constant external diameter at the level of the first and second zones. Advantageously, the skirt has a free chamfered lower end to facilitate its insertion into the opening of the container.
L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif un mode de réalisation de l'invention. Sur les figures :The invention will now be described more fully with reference to the accompanying drawings which give an embodiment of the invention by way of non-limiting example. In the figures:
- la figure 1 est une vue en section transversale à travers un distributeur de produit fluide selon l'invention, juste avant emmanchage de la bague dans l'ouverture de récipient,FIG. 1 is a cross-section view through a fluid dispenser according to the invention, just before the ring is fitted into the container opening,
- la figure 2 est une vue similaire à celle de la figure 1 avec la bague emmanchée dans l'ouverture du récipient, etFIG. 2 is a view similar to that of FIG. 1 with the ring fitted into the opening of the container, and
- la figure 3 est une vue agrandie d'un détail de la bague montrant la coopération de la jupe avec l'ouverture.- Figure 3 is an enlarged view of a detail of the ring showing the cooperation of the skirt with the opening.
Sur les figures 1 et 2, il n'a été représenté que la partie supérieure d'un distributeur de produit fluide selon l'invention, de sorte que le récipient n'est représenté que par son col 10. Toutefois, le distributeur de l'invention comprend trois éléments constitutifs, à savoir un récipient 1, un organe de distribution 2 et une bague de fixation 3.In FIGS. 1 and 2, only the upper part of a fluid dispenser according to the invention has been shown, so that the container is only represented by its neck 10. However, the dispenser of the The invention comprises three constituent elements, namely a container 1, a dispensing member 2 and a fixing ring 3.
Le récipient 1 est ici pourvu d'un col 10 qui fait saillie vers le haut à partir du corps du récipient dont la fonction est de stocker du produit fluide. Le col 10 définit une ouverture qui permet de communiquer à l'intérieur du récipient. On peut cependant imaginer d'autres formes de réalisation pour le récipient, dans lesquelles il n'y a pas de col saillant, mais simplement une ouverture dans le corps du récipient. En se référant aux figures 1 et 2, on peut par exemple imaginer que la partie terminale du col 10 soit située directement au niveau de l'épaulement 110. On peut alors parler d'ouverture sans col. Le col saillant n'est donc pas un élément indispensable dans la présente invention. Il suffit qu'il y ait une ouverture présentant certaines caractéristiques. Parmi ces caractéristiques, on peut voir sur les figures 1 et 2 que le col 10 comprend une paroi interne 11 qui n'est pas cylindrique, mais présente au contraire une section d'ouverture rétrécie 13 en dessous de laquelle est définie une section d'ouverture évidée 14. La section d'ouverture rétrécie 13 est située à proximité de la sortie du col qui forme à cet endroit une extrémité supérieure 12 de forme annulaire. Avantageusement, la section d'ouverture rétrécie 13 se raccorde à l'extrémité supérieure 12 par une section d'attaque tronconique ou évasée 15. D'autre part, la section d'ouverture rétrécie 13 se raccorde à la section d'ouverture évidée 14 par une section de transition tronconique ou évasée 16. La section d'ouverture rétrécie 13 peut être sensiblement cylindrique. La section d'ouverture évidée 14 peut également être de section sensiblement cylindrique. On peut imaginer que la section d'ouverture évidée 14 se présente sous la forme d'un évidement périphérique qui s'étend sur une certaine hauteur du col, qui se prolonge vers le bas par une autre section de diamètre sensiblement égal à celui de la section d'ouverture rétrécie 13. On peut également imaginer que la section d'ouverture évidée se présente sous la forme d'une pluralités d'évidements répartis sur la périphérie interne du col. En d'autres termes, quelle que soit la forme de la section d'ouverture évidée 14, il faut qu'elle présente au moins localement un diamètre interne supérieur à celui de la section d'ouverture rétrécie 13. Dans la forme de réalisation des figures, la section d'ouverture rétrécie 13 est cylindrique, et la section d'ouverture évidée 14 s'étend vers le bas à partir de la section d'ouverture rétrécie 13 en commençant par la section de transition évasée 16. On peut considérer que la section de transition évasée 16 fait partie de la section d'ouverture évidée 14 puisque son diamètre est inférieur à celui de la section d'ouverture rétrécie 13. La section d'ouverture évidée 14 se prolonge ensuite vers le bas pour se raccorder à l'épaulement 110. On peut bien entendu imaginer qu'il n'y a pas de section de transition 16 et que la section d'ouverture évidée 14 se raccorde à la section d'ouverture rétrécie 13 par un épaulement à angle vif. Dans ce cas, il n'est pas nécessaire d'avoir un col qui s'étend sur une certaine hauteur, et une telle ouverture avec une section rétrécie et une section évidée peut être réalisée au niveau de l'épaulement 110.The container 1 is here provided with a neck 10 which projects upwards from the body of the container, the function of which is to store fluid product. The neck 10 defines an opening which makes it possible to communicate inside the container. One can however imagine other embodiments for the container, in which there is no protruding neck, but simply an opening in the body of the container. Referring to Figures 1 and 2, one can for example imagine that the end portion of the neck 10 is located directly at the shoulder 110. We can then speak of opening without neck. The protruding neck is therefore not an essential element in the present invention. It is enough that there is an opening with certain characteristics. Among these characteristics, it can be seen in FIGS. 1 and 2 that the neck 10 comprises an internal wall 11 which is not cylindrical, but on the contrary has a narrowed opening section 13 below which is defined a section of recessed opening 14. The narrowed opening section 13 is located near the outlet of the neck which forms an upper end 12 of annular shape at this location. Advantageously, the narrowed opening section 13 is connected to the upper end 12 by a tapered or flared attack section 15. On the other hand, the narrowed opening section 13 is connected to the hollowed opening section 14 by a frustoconical or flared transition section 16. The narrowed opening section 13 can be substantially cylindrical. The recessed opening section 14 can also be of substantially cylindrical section. One can imagine that the recessed opening section 14 is in the form of a peripheral recess which extends over a certain height of the neck, which is extended downwards by another section of diameter substantially equal to that of the narrowed opening section 13. One can also imagine that the hollowed out opening section is in the form of a plurality of recesses distributed over the internal periphery of the neck. In other words, whatever the shape of the recessed opening section 14, it must at least locally have an internal diameter greater than that of the narrowed opening section 13. In the embodiment of the Figures, the narrowed opening section 13 is cylindrical, and the recessed opening section 14 extends downward from the narrowed opening section 13 starting with the flared transition section 16. It can be considered that the flared transition section 16 is part of the recessed opening section 14 since its diameter is less than that of the narrowed opening section 13. The recessed opening section 14 then extends downward to connect to the shoulder 110. It can of course be imagined that there is no transition section 16 and that the recessed opening section 14 is connected to the narrowed opening section 13 by a sharp angle shoulder. In this case, it is not necessary to have a collar which extends over a certain height, and such opening with a narrowed section and a hollowed out section can be produced at the level of the shoulder 110.
L'organe de distribution 2, qui est ici une pompe ou une valve, comprend un corps de pompe 20 définissant à son extrémité supérieure une collerette 21 qui fait saillie vers l'extérieur. En dessous de cette collerette, le corps de pompe définit une partie de corps 201 en dessous de laquelle se raccorde une seconde partie de corps 202 de diamètre inférieur de sorte qu'entre les deux parties de corps 201 et 202 il y a une transition 203 sous la forme d'un gradin tronconique, comme on peut le voir plus clairement sur la figure 3. En dessous de la seconde partie de corps 202, le corps 20 définit une autre partie de corps présentant encore un diamètre inférieur. On peut dire que le corps 20 est étage quatre fois, puisqu'il comprend quatre parties de corps de diamètre décroissant en partant de la collerette 21. Il ne s'agit que d'une forme de réalisation particulière, et on peut bien entendu imaginer un corps 20 parfaitement cylindrique. De manière classique, la pompe 2 comprend une tige d' actionnement 22 qui coulisse à l'intérieur du corps 20. Cette tige d' actionnement 22 est surmontée d'un poussoir 23 définissant un orifice de distribution 230. Pour actionner la pompe 2, il suffit d'appuyer sur le poussoir 23 pour enfoncer la tige 22 dans le corps 20 ce qui a pour effet de refouler une dose de produit à travers la tige 22 jusqu'à l'orifice de distribution 230. Il s'agit là d'une pompe ou d'une valve tout à fait classique.The dispensing member 2, which is here a pump or a valve, comprises a pump body 20 defining at its upper end a flange 21 which projects outwards. Below this flange, the pump body defines a body part 201 below which a second body part 202 of smaller diameter is connected so that between the two body parts 201 and 202 there is a transition 203 in the form of a frustoconical step, as can be seen more clearly in FIG. 3. Below the second body part 202, the body 20 defines another body part which also has a smaller diameter. We can say that the body 20 is four stages, since it comprises four parts of the body decreasing in diameter from the flange 21. This is only a particular embodiment, and one can of course imagine a perfectly cylindrical body 20. Conventionally, the pump 2 comprises an actuating rod 22 which slides inside the body 20. This actuating rod 22 is surmounted by a pusher 23 defining a dispensing orifice 230. To actuate the pump 2, it suffices to press the pusher 23 to push the rod 22 into the body 20 which has the effect of pushing a dose of product through the rod 22 to the dispensing orifice 230. This is d 'a completely classic pump or valve.
La bague de fixation 3 a pour but de maintenir l'organe de distribution 2 et de la fixer dans l'ouverture du col 10. La bague de fixation 3 comprend pour cela des moyens de réception 31 sous la forme d'un manchon qui est engagé avec frottement sur la première partie de corps 201 de plus grand diamètre. L'extrémité du manchon 31 prend avantageusement appui sous la collerette saillante 21. La mise en place de la bague 3 sur le corps 20 de la pompe 2 peut être réalisée par emmanchage en force. La bague de fixation 3 comprend également une jupe de fixation 32 destinée à être insérée à l'intérieur du col 10. Cette jupe 32 s'étend sensiblement dans le prolongement du manchon 31. On peut remarquer sur la figure 3 que la jupe 31 n'est pas en contact du corps 20 au niveau de la seconde partie de corps 202, mais qu'il subsiste un espace intermédiaire 34 qui empêche tout contact ou interférence de la jupe 32 sur le corps 20. Ceci est possible du fait que le corps 20 est étage, mais on aurait pu obtenir le même espace intermédiaire 34 en étageant la jupe par rapport au manchon 31. La jupe présente une paroi externe 320 qui est sensiblement cylindrique avant emmanchage de la jupe 32 dans le col 10, comme on peut le voir sur la figure 1. A son extrémité inférieure, la jupe peut être formée avec un chanfrein 323 qui permet de faciliter l'insertion de la jupe dans l'ouverture du col 10. Cependant, au-dessus du chanfrein 323, la paroi externe 320 de la jupe est sensiblement cylindrique. Selon l'invention, le diamètre externe de la jupe 32 au niveau de sa paroi externe cylindrique 320 est supérieur au diamètre interne de la section d'ouverture rétrécie 13. Ainsi, pour mettre en place la jupe 32 dans l'ouverture du col, comme représenté sur les figures 2 et 3, il est nécessaire de l'emmancher en force. Pour limiter la profondeur d'emmanchage de la jupe dans l'ouverture du col, la bague 3 comprend une bride périphérique 33 qui s'étend radialement vers l'extérieur à partir de l'extrémité supérieure de la jupe 32. La position finale d'emmanchage maximal est atteinte lorsque la bride 33 prend appui sur l'extrémité supérieure 12 du col 10 comme on peut le voir sur les figures 2 et 3. La jupe 32 s'étend alors à la fois au niveau de la section d'ouverture rétrécie 13 et de la section d'ouverture évidée 14. Plus précisément, la jupe 32 s'étend également au niveau de la section d'attaque 15 et de la section de transition 16. On peut grossièrement définir deux zones de la paroi externe 320 de la jupe 32, à savoir une première zone 321 qui vient se placer au niveau de la section d'ouverture rétrécie 13 et une seconde zone 322 qui vient se placer au niveau de la section d'ouverture évidée 14. Avant emmanchage, ces zones ne sont pas différentiables, comme on peut le voir sur la figure 1, étant donné que la paroi externe 320 de la jupe 32 est cylindrique. On peut voir sur la figure 3, que la première zone 321 est déformée radialement vers l'intérieur par la section d'ouverture rétrécie 13, alors que la seconde zone 322 reste non déformée, puisqu'elle n'est pas en contact de la paroi interne 11 du col au niveau de la section d'ouverture évidée 14. La jupe 32, au niveau de la première zone 321, a donc subi une déformation par fluage de matière. Pour permettre ce fluage de matière, il est nécessaire que la section d'ouverture rétrécie 13 reste non déformée lors de l'emmanchage de la jupe 32 dans l'ouverture du col. En pratique, ceci peut être obtenu en utilisant des matériaux de dureté différente pour le col et la bague de fixation. Par exemple, le récipient 1 peut être réalisé en verre, et la bague de fixation 3 en plastique. Il est cependant également possible de réaliser le récipient 1 et la bague de fixation 3 avec un même matériau : les caractéristiques de déformabilité de la jupe 32 peuvent alors être obtenues de par sa conception ou son épaisseur de paroi par exemple. Une meilleure déformation de la première zone peut également être obtenue par une hauteur limitée de la section d'ouverture rétrécie. Celle-ci peut même être réduite à une sorte de cordon ou arête qui vient mordre dans la première zone de la jupe.The purpose of the fixing ring 3 is to hold the dispensing member 2 and to fix it in the opening of the neck 10. The fixing ring 3 therefore comprises reception means 31 in the form of a sleeve which is engaged with friction on the first body part 201 of larger diameter. The end of the sleeve 31 advantageously bears under the protruding flange 21. The positioning of the ring 3 on the body 20 of the pump 2 can be achieved by force fitting. The fixing ring 3 also comprises a fixing skirt 32 intended to be inserted inside the neck 10. This skirt 32 extends substantially in the extension of the sleeve 31. It can be seen in FIG. 3 that the skirt 31 n is not in contact with the body 20 at the second body part 202, but that there remains a space intermediate 34 which prevents any contact or interference of the skirt 32 on the body 20. This is possible because the body 20 is tiered, but the same intermediate space 34 could have been obtained by staggering the skirt relative to the sleeve 31. The skirt has an external wall 320 which is substantially cylindrical before fitting the skirt 32 into the neck 10, as can be seen in FIG. 1. At its lower end, the skirt can be formed with a chamfer 323 which makes it easier to insertion of the skirt into the opening of the neck 10. However, above the chamfer 323, the external wall 320 of the skirt is substantially cylindrical. According to the invention, the external diameter of the skirt 32 at its cylindrical external wall 320 is greater than the internal diameter of the narrowed opening section 13. Thus, to put the skirt 32 in place in the opening of the neck, as shown in Figures 2 and 3, it is necessary to press it in force. To limit the depth of fitting of the skirt in the opening of the neck, the ring 3 comprises a peripheral flange 33 which extends radially outwards from the upper end of the skirt 32. The final position d maximum engagement is reached when the flange 33 is supported on the upper end 12 of the neck 10 as can be seen in Figures 2 and 3. The skirt 32 then extends both at the opening section narrowed 13 and of the recessed opening section 14. More precisely, the skirt 32 also extends at the level of the leading section 15 and the transition section 16. Two zones of the external wall 320 can be roughly defined of the skirt 32, namely a first zone 321 which is placed at the level of the narrowed opening section 13 and a second zone 322 which is placed at the level of the recessed opening section 14. Before fitting, these zones are not differentiable, as we can see in Figure 1, since the outer wall 320 of the skirt 32 is cylindrical. It can be seen in FIG. 3, that the first zone 321 is deformed radially inwards by the narrowed opening section 13, while the second zone 322 remains undeformed, since it is not in contact with the internal wall 11 of the neck at the level of the recessed opening section 14. The skirt 32, at the level of the first zone 321, has therefore underwent deformation by material creep. To allow this material flow, it is necessary that the narrowed opening section 13 remains undeformed when the skirt 32 is fitted into the neck opening. In practice, this can be achieved by using materials of different hardness for the neck and the fixing ring. For example, the container 1 can be made of glass, and the fixing ring 3 of plastic. However, it is also possible to produce the container 1 and the fixing ring 3 with the same material: the deformability characteristics of the skirt 32 can then be obtained by its design or its wall thickness, for example. Better deformation of the first zone can also be obtained by a limited height of the narrowed opening section. This can even be reduced to a kind of cord or edge which comes to bite in the first zone of the skirt.
On peut remarquer que la paroi externe 320 de la jupe 32 vient également en contact de la section d'attaque 15 et de la section de transition 16. Ceci contribue à la fixation de la jupe dans l'ouverture par un phénomène de harponnage en se servant de la section d'ouverture rétrécie comme profil incident. Il ne s'agit pas ici d'un encliquetage, puisque la jupe ne comporte à l'origine, c'est à dire avant emmanchage, aucun logement destiné à recevoir la section d'ouverture rétrécie 13. On peut également noter que l'étanchéité est significativement améliorée avec une telle jupe, étant donné que le serrage radial au niveau de la première zone 321 est très fort, et de toute façon bien supérieur à une fixation par simple encliquetage comme dans le document US 3 937 366 de l'art antérieur.It can be noted that the external wall 320 of the skirt 32 also comes into contact with the leading section 15 and the transition section 16. This contributes to the fixing of the skirt in the opening by a spear-phoning phenomenon while being serving as the narrowed opening section as an incident profile. This is not a click-in here, since the skirt does not originally have, that is to say before fitting, no housing intended to receive the narrowed opening section 13. It may also be noted that the sealing is significantly improved with such a skirt, since the radial tightening at the level of the first zone 321 is very strong, and in any case much greater than a fixing by simple snap-fastening as in document US Pat. No. 3,937,366 prior.
La paroi externe 320 de la jupe 32 a été représentée ici de manière parfaitement cylindrique. On peut toutefois imaginer d'autres formes pour la paroi externe 320 de la jupe 32, par exemple étage, avec le diamètre externe de la seconde zone 322 ayant un diamètre supérieur ou inférieur à celui de la première zone 321. L'esprit de l'invention réside dans le fait que la jupe 32, avant emmanchage dans l'ouverture du col, présente un diamètre supérieur à celui de la section d'ouverture rétrécie 13 de manière à forcer la jupe à fluer autour de la section d'ouverture rétrécie 13. The outer wall 320 of the skirt 32 has been shown here in a perfectly cylindrical manner. One can however imagine other shapes for the external wall 320 of the skirt 32, for example a stage, with the external diameter of the second zone 322 having a diameter greater or less than that of the first zone 321. The spirit of the invention lies in the fact that the skirt 32, before fitting into the opening of the neck, has a diameter greater than that of the narrowed opening section 13 so as to force the skirt to creep around the narrowed opening section 13.
