Description

ORGANE DE FIXATION POUR UN DISTRIBUTEUR FIXING MEMBER FOR A DISTRIBUTOR
La présente invention concerne un distributeur de produit fluide comprenant un organe de distribution tel qu'une pompe ou une valve, un récipient formant un col et un organe de fixation pour fixer l'organe de distribution sur le col du récipient. La présente invention a également trait à un tel organe de fixation. L'organe de fixation comprend une jupe définissant une paroi interne destinée à coopérer avec le col du récipient.The present invention relates to a fluid dispenser comprising a dispensing member such as a pump or a valve, a container forming a neck and a fixing member for fixing the dispensing member on the neck of the container. The present invention also relates to such a fixing member. The fixing member comprises a skirt defining an internal wall intended to cooperate with the neck of the container.
De tels distributeurs utilisant un tel organe de fixation sont couramment employés dans le domaine de la parfumerie, de la cosmétique, ou encore de la parfumerie pour distribuer des produits fluides.Such dispensers using such a fixing member are commonly used in the field of perfumery, cosmetics, or even perfumery for dispensing fluid products.
On connaît dans l'art antérieur plusieurs types d'organes de fixation que l'on désigne couramment sous le terme de bague de fixation. De telles bagues définissent en général une jupe qui s'étend vers le bas, et qui est destinée à coopérer avec une partie renforcée formée par le col du récipient. Cette partie renforcée ou épaissie souvent désignée sous le terme de « carnette » fait saillie vers l'extérieur et forme un épaulement inférieur. La jupe de la bague comprend un cordon continu ou des têtes d'encliquetage destinées à venir en prise sous l'épaulement que forme la carnette. La jupe peut être continue, ou encore fendue sur sa hauteur pour former des pattes aux extrémités desquelles sont formées les têtes d'encliquetage. Lorsque la jupe est fendue et forme des pattes et des têtes d'encliquetage, il est en général prévu une frette d'habillage qui vient coiffer et recouvrir la jupe de manière à bloquer les têtes d'encliquetage sous l'épaulement de la carnette. Dans le cas où la jupe est continue et forme un cordon d'encliquetage interne continu, la frette d'habillage n'est pas nécessaire et ne remplit dans ce cas qu'une fonction esthétique. Dans les deux cas, que la jupe soit continue ou fendue, le cordon ou les têtes d'encliquetage coopèrent avec l'épaulement de la camette. La jupe n'a aucune interaction avec la portée extérieure cylindrique de la carnette dans un but de fixation.Several types of fixing members are known in the prior art which are commonly referred to as the fixing ring. Such rings generally define a skirt which extends downwards, and which is intended to cooperate with a reinforced part formed by the neck of the container. This reinforced or thickened part often designated by the term of "carnette" protrudes outwards and forms a lower shoulder. The skirt of the ring comprises a continuous cord or snap-on heads intended to come into engagement under the shoulder formed by the carnette. The skirt can be continuous, or even split over its height to form legs at the ends of which the latching heads are formed. When the skirt is split and forms legs and latching heads, there is generally provided a covering hoop which covers and covers the skirt so as to block the latching heads under the shoulder of the booklet. In the case where the skirt is continuous and forms a continuous internal latching cord, the covering band is not necessary and in this case fulfills only an aesthetic function. In both cases, whether the skirt is continuous or split, the cord or the latching heads cooperate with the shoulder of the camette. The skirt has no interaction with the cylindrical outer surface of the bag for the purpose of fixing.
Une telle jupe, fendue ou non, est cependant facilement sujette à des déformations du fait que le cordon ou les têtes doivent être mises en place en force sous l'épaulement de la carnette. Dans le cas de pattes d'encliquetage équipées de têtes, cette déformation plastique de la jupe a lieu sous l'effet de la frette d'habillage lors de son montage. Dans le cas d'une jupe continue équipée d'un cordon d'encliquetage interne continu, il arrive parfois que la déformation de la jupe soit visible de l'extérieur.Such a skirt, split or not, is however easily subject to deformations due to the fact that the cord or the heads must be put in place by force under the shoulder of the book. In the case of latching tabs fitted with heads, this plastic deformation of the skirt takes place under the effect of the covering hoop during its mounting. In the case of a continuous skirt fitted with a continuous internal latching cord, it sometimes happens that the deformation of the skirt is visible from the outside.
La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant un organe de fixation dont la jupe ne subit extérieurement aucune déformation, et qui peut de surcroît réaliser une fixation efficace sans l'utilisation de la frette d'habillage pour la bloquer sur le col du récipient. Pour ce faire, la présente invention propose que ladite paroi interne est formée avec au moins deux nervures longitudinales s'étendant sur la hauteur de la jupe, lesdites nervures coopérant par déformation plastique avec une partie externe du col.The object of the present invention is to remedy the aforementioned drawbacks of the prior art by defining a fixing member whose skirt does not undergo any deformation on the outside, and which can moreover achieve effective fixing without the use of the covering band to block it on the neck of the container. To do this, the present invention proposes that said internal wall is formed with at least two longitudinal ribs extending over the height of the skirt, said ribs cooperating by plastic deformation with an external part of the neck.
Contrairement au cordon ou à la tête d'encliquetage qui sont situés sous l'épaulement de la carnette, et qui ne coopère par conséquent qu'avec cet épaulement, les nervures de la présente invention s'étendent sur la hauteur de la carnette, et avantageusement encore en dessous de la carnette de sorte que le contact de la jupe avec le col est réalisé sur une grande partie de la hauteur de la jupe.Unlike the cord or the latching head which are located under the shoulder of the bag, and which therefore only cooperates with this shoulder, the ribs of the present invention extend over the height of the bag, and advantageously still below the bag so that the contact of the skirt with the collar is made over a large part of the height of the skirt.
Selon une forme de réalisation, les nervures définissent un diamètre interne inférieur au diamètre externe du col avant montage de l'organe de fixation sur le col, de sorte que les nervures sont déformées plastiquement sur une portée externe du col après montage. Etant donné que les nervures s'étendent longitudinalement et qu'elles sont espacées l'une de l'autre, elles peuvent être relativement facilement déformées plastiquement sur la carnette du col sans endommager ou déformer la paroi externe de la jupe. Selon une autre forme de réalisation, la partie renforcée ou carnette est formée avec au moins un relief de rétention dans lesquels les nervures pénètrent par déformation plastique.According to one embodiment, the ribs define an internal diameter smaller than the external diameter of the neck before mounting of the fixing member on the neck, so that the ribs are plastically deformed on an outer surface of the neck after mounting. Since the ribs extend longitudinally and are spaced from one another, they can be relatively easily plastically deformed on the neck collar without damaging or deforming the outer wall of the skirt. According to another embodiment, the reinforced part or bag is formed with at least one retention relief in which the ribs penetrate by plastic deformation.
Avantageusement, ledit au moins un relief s'étend sur la périphérie de la partie renforcée. Le relief peut par exemple se présenter sous la forme d'une ou de plusieurs gorges circulaires formées dans la portée externe sensiblement cylindrique de la carnette. On peut bien entendu imaginer toute forme de profil extérieur de la portée de la carnette permettant d'améliorer l'accrochage des nervures par déformation plastique. Par profil, il faut donc comprendre tout état de surface de la portée externe de la carnette permettant d'améliorer la rétention de l'organe de fixation. En variante, ledit au moins un profil s'étend sur la hauteur de la partie renforcée, avantageusement sous la forme d'une saignée verticale, ledit profil présentant une largeur inférieure à la largeur d'une nervure de manière à maintenir la nervure par déformation plastique dans ledit profil. Dans ce cas, le profil n'est plus périphérique, mais vertical à travers la carnette du col. Avantageusement, le profil présente une largeur décroissante à partir de l'extrémité supérieure du col. Le profil est de préférence plus large que la nervure au niveau de l'extrémité supérieure du col et forcément moins large que la nervure au niveau de son extrémité inférieure. Ceci permet d'une part de faciliter l'introduction de la nervure dans la saignée, et d'autre part, de retenir la nervure dans la saignée par un effet de harponnage. Selon une autre caractéristique de l'invention, la jupe comprend des évidements internes longitudinaux situés radialement derrière les nervures et ménagés dans l'épaisseur de la jupe, de sorte que les nervures peuvent être déformées radialement vers l'extérieur dans leurs évidements respectifs sans déformer la paroi externe de la jupe. Les évidements internes permettent une déformation des nervures internes sans influer sur la paroi externe de la jupe. Ceci permet de pouvoir prémonter une frette sur la jupe. La frette peut avantageusement être en contact avec la paroi externe de la jupe sur toute sa périphérie, y compris au niveau des évidements internes. Bien entendu, par évidements internes, on entend des évidements qui ne débouchent pas sur la paroi externe de la jupe qui peut par conséquent rester parfaitement cylindrique circulaire. De préférence, les évidements sont ouverts ou débouchent au niveau de l'extrémité inférieure de la jupe et se présentent donc sous la forme de trous borgnes s'étendant axialement dans l'épaisseur de la paroi de la jupe depuis son extrémité inférieure. Et pour permettre une bonne déformation par élasticité des nervures, il est avantageux que les évidements soient plus larges que les nervures. On peut également imaginer une jupe fendue formant des pattes à l'intérieur desqueËes les nervures sont formées. Dans ce cas, l'organe de fixation comprend une frette d'habillage qui recouvre au moins partiellement la jupe. Etant donné que les nervures sont déformables sans pour autant déformer la paroi externe de la jupe, la frette d'habillage peut être montrée sur l'organe de fixation avant son montage sur le col du récipient. Ainsi, l'organe de fixation et la frette peuvent être montées comme un ensemble unitaire sur le col du récipient.Advantageously, said at least one relief extends over the periphery of the reinforced part. The relief may for example be in the form of one or more circular grooves formed in the substantially cylindrical outer surface of the Carnette. One can of course imagine any form of external profile of the scope of the carnette making it possible to improve the attachment of the ribs by plastic deformation. By profile, it is therefore necessary to understand any surface condition of the external surface of the carnette making it possible to improve the retention of the fixing member. As a variant, said at least one profile extends over the height of the reinforced part, advantageously in the form of a vertical groove, said profile having a width less than the width of a rib so as to maintain the rib by deformation plastic in said profile. In this case, the profile is no longer peripheral, but vertical across the neck flap. Advantageously, the profile has a decreasing width from the upper end of the neck. The profile is preferably wider than the rib at the upper end of the neck and necessarily narrower than the rib at its lower end. This allows on the one hand to facilitate the introduction of the rib into the groove, and on the other hand, to retain the rib in the groove by a harpooning effect. According to another characteristic of the invention, the skirt comprises longitudinal internal recesses located radially behind the ribs and formed in the thickness of the skirt, so that the ribs can be deformed radially outward in their respective recesses without deforming the outer wall of the skirt. The internal recesses allow a deformation of the internal ribs without influencing the external wall of the skirt. This allows you to pre-mount a hoop on the skirt. The hoop can advantageously be in contact with the external wall of the skirt over its entire periphery, including at the level of the internal recesses. Of course, by internal recesses is meant recesses which do not open onto the external wall of the skirt which can therefore remain perfectly circular cylindrical. Preferably, the recesses are open or open at the lower end of the skirt and are therefore in the form of blind holes extending axially in the thickness of the wall of the skirt from its lower end. And to allow good deformation by elasticity of the ribs, it is advantageous that the recesses are wider than the ribs. One can also imagine a split skirt forming legs inside which the ribs are formed. In this case, the fixing member comprises a trim band which at least partially covers the skirt. Since the ribs are deformable without deforming the external wall of the skirt, the covering band can be shown on the fixing member before it is mounted on the neck of the container. Thus, the fixing member and the hoop can be mounted as a unitary assembly on the neck of the container.
La présente invention a également pour objet un organe de fixation dont la paroi interne de la jupe définit des nervures longitudinales adaptées à venir en prise par déformation plastique avec la partie externe du col.The present invention also relates to a fixing member whose internal wall of the skirt defines longitudinal ribs adapted to come into engagement by plastic deformation with the external part of the neck.

On se référera tout d'abord aux figures la et lb pour expliquer un premier mode de réalisation. L'organe de fixation comprend une bague 2, par exemple réalisée en matière plastique moulée, qui forme un logement de réception 21 destinée à recevoir par encliquetage en force un organe de distribution (non représenté) tel qu'une valve ou une pompe. En général, la valve ou la pompe forme sur son corps une collerette renforcée adaptée à venir s'encliqueter dans le logement 21. La tige d'actionnement de la valve ou de la pompe passe à travers une ouverture 24 ménagée dans la bague. Le logement de réception 21 se raccorde sur sa périphérie extérieure à un plateau 22 destiné à venir en contact d'appui sur un joint 4 interposé entre le plateau 22 et l' extrémité supérieure du col du récipient. Le plateau 22 se raccorde sur sa périphérie extérieure à une jupe 20 qui présente une forme extérieure essentiellement cylindrique. La jupe 20 s'étend vers le bas à partir du plateau 22 mais peut également s'étendre vers le haut comme représenté sur la figure lb. La jupe 20, dans sa partie s'étendant vers le bas, coopère avec un col 10 d'un récipient 1 qui forme avantageusement une partie épaissie ou renforcée 11 qui fait saillie vers l'extérieur et qui est communément désignée sous le terme de carnette. La camette s'étend jusqu'à l'extrémité supérieure du col 10 où est formé un jonc d'étanchéité 14 sur lequel le joint souple 4 est déformé. La camette s'étend vers le bas sur une certaine distance puis forme un épaulement pour relier la partie cylindrique de diamètre réduit du col.We will first refer to Figures la and lb to explain a first embodiment. The fixing member comprises a ring 2, for example made of molded plastic, which forms a receiving housing 21 intended to receive by force snap-fastening a dispensing member (not shown) such as a valve or a pump. In general, the valve or the pump forms on its body a reinforced flange adapted to snap into the housing 21. The actuating rod of the valve or of the pump passes through an opening 24 made in the ring. The receiving housing 21 is connected on its outer periphery to a plate 22 intended to come into bearing contact on a seal 4 interposed between the plate 22 and the upper end of the neck of the container. The plate 22 is connected on its outer periphery to a skirt 20 which has an essentially cylindrical external shape. The skirt 20 extends downwards from the plate 22 but can also extend upwards as shown in FIG. 1b. The skirt 20, in its part extending downwards, cooperates with a neck 10 of a container 1 which advantageously forms a thickened or reinforced part 11 which projects outwards and which is commonly referred to as a carnette . The camette extends to the upper end of the neck 10 where a sealing ring 14 is formed on which the flexible seal 4 is deformed. The camette extends down a certain distance and then forms a shoulder to connect the cylindrical part of reduced diameter of the neck.
Selon l'invention, la jupe 20 présente une paroi interne formée avec plusieurs nervures 23 qui s'étendent verticalement sur une partie ou sur la totalité de la hauteur de la jupe 20. Dans le mode de réalisation représenté sur les figures la et lb, ces nervures 23 sont au nombre de huit réparties de manière régulière sur la périphérie interne de la paroi interne de la jupe 20. Les nervures 23 s'étendent avantageusement sur une hauteur supérieure à celle de la carnette 11. On peut également imaginer des formes de réalisation où des nervures s'étendent sur une hauteur sensiblement égale ou légèrement inférieure à celle de la camette. Selon l'invention, les nervures 23 définissent un cylindre fictif passant par les extrémités des nervures : ce cylindre fictif présente un diamètre inférieur au diamètre externe de la carnette 11 de sorte que les nervures 23, une fois la jupe 20 montée sur le col 10 du récipient 1, sont déformées plastiquement contre la portée externe sensiblement cylindrique de la camette 11. Afin d'améliorer le maintien des nervures sur la carnette, celles-ci peuvent avantageusement s'étendre jusqu'en dessous de l'épaulement de la camette de manière à épouser cet épaulement, ce qui contribue à l'accrochage de la jupe sur le col. Il est également possible de former la portée externe de la camette 11 avec un profil permettant d'améliorer l'accrochage des nervures. Sur la figure 1, la portée externe de la camette 11 est formée avec un profil que se présente sous la forme d'une gorge annulaire 12 qui s'étend sur toute ou partie de la périphérie de la carnette. Il est également possible de prévoir plusieurs profils de ce type. Ainsi, les nervures peuvent pénétrer par fluage plastique à l'intérieur de ces profils et ainsi améliorer l'accrochage de la jupe 20 sur le col 10. Lorsque la carnette 11 est pourvue de tels profils ou gorges, les nervures n'ont pas besoin de s'étendre jusqu'en dessous de l'épaulement de la camette. En d'autres termes, Un accrochage de la bague sur le col peut être réalisé sans que la jupe ne coopère avec l'épaulement de la carnette, contrairement à l'art antérieur précité. Une portée extérieure profilée de la carnette suffit à réaliser un maintien efficace des nervures de la jupe sur le col. Etant donné que les nervures sont disposées de manière séparée et ne constituent que des renforcements ponctuels dans le sens de l'introduction de la bague sur le col, celles-ci peuvent se déformer sans pour autant déformer la jupe 20 sur sa paroi extérieure.According to the invention, the skirt 20 has an internal wall formed with several ribs 23 which extend vertically over part or over the entire height of the skirt 20. In the embodiment shown in FIGS. 1 a and 1 b, these ribs 23 are eight in number distributed regularly over the internal periphery of the internal wall of the skirt 20. The ribs 23 advantageously extend over a height greater than that of the carnette 11. One can also imagine shapes of embodiment where ribs extend over a height substantially equal to or slightly less than that of the camette. According to the invention, the ribs 23 define a fictitious cylinder passing through the ends of the ribs: this fictitious cylinder has a diameter less than the external diameter of the bag 11 so that the ribs 23, once the skirt 20 is mounted on the neck 10 of the container 1, are plastically deformed against the substantially cylindrical outer surface of the camette 11. In order to improve the retention of the ribs on the carnette, these can advantageously extend up to below the shoulder of the camette. way to fit this shoulder, which contributes to hanging the skirt on the collar. It is also possible to form the outer surface of the camette 11 with a profile making it possible to improve the attachment of the ribs. In Figure 1, the outer surface of the sump 11 is formed with a profile which is in the form of an annular groove 12 which extends over all or part of the periphery of the carnette. It is also possible to provide several profiles of this type. Thus, the ribs can penetrate by plastic creep inside these profiles and thus improve the attachment of the skirt 20 on the neck 10. When the carnette 11 is provided with such profiles or grooves, the ribs do not need to extend to below the shoulder of the camette. In other words, an attachment of the ring on the neck can be achieved without the skirt cooperating with the shoulder of the bag, unlike the aforementioned prior art. A profiled outer reach of the bag is sufficient to effectively maintain the ribs of the skirt on the collar. Since the ribs are arranged separately and only constitute point reinforcements in the direction of introduction of the ring on the neck, these can deform without deforming the skirt 20 on its outer wall.
Il est à noter que l'accrochage de la jupe 20 sur le col est réalisé sans avoir besoin d'une frette d'habillage 3, telle que représentée sur la figure lb, et qui sert dans les organes de fixation de l'art antérieur à bloquer les têtes d'encliquetage sous l'épaulement de la camette. Ici, la frette d'habillage 3 n'a qu'une fonction esthétique et peut être prémontée sur la bague 2 avant son montage sur le col du récipient. Ceci est en effet possible du fait que la déformation plastique des nervures n'engendre pas de déformation de la jupe 20 au niveau de sa paroi externe. On peut par conséquent dans certaines applications se passer de la frette d'habillage 3.It should be noted that the attachment of the skirt 20 to the neck is carried out without the need for a covering band 3, as shown in FIG. 1b, which is used in the fastening members of the prior art to lock the latching heads under the shoulder of the camette. Here, the covering band 3 has only an aesthetic function and can be pre-assembled on the ring 2 before it is mounted on the neck of the container. This is in fact possible because the plastic deformation of the ribs does not cause deformation of the skirt 20 at its external wall. It is therefore possible in certain applications to do without the covering band 3.
On se référera maintenant aux figures 2, 3a et 3b pour expliquer un second mode de réalisation selon l'invention. Dans ce mode de réalisation, la bague 20 est également formée avec des nervures 23 qui s'étendent verticalement sur une partie de la hauteur de la jupe. Tout comme dans le mode de réalisation précédent, ces nervures 23 coopèrent avec la carnette 11 du col 10 du récipient. Selon l'invention, plusieurs saignées verticales peuvent être réalisées dans la camette 11. Ces profils ou saignées peuvent s'étendre du haut en bas de la carnette, de sorte que la carnette est interrompue à cet endroit, mais la saignée peut également s'étendre seulement sur une partie de la hauteur de la camette à partir de son extrémité supérieure en laissant l'extrémité inférieure de la carnette intacte. Dans le mode de réalisation utilisé pour illustrer la présente invention, la saignée 15 s'étend de part en part de la carnette. Sur la figure 3a, on voit que la camette 11 est formée avec deux saignées de ce type. Bien entendu, on peut prévoir plus de deux saignées de ce type, par exemple répartis de manière régulière sur la périphérie du col. Selon l'invention, les nervures 23 formées sur la jupe 20, qui sont également au nombre de deux, sont adaptées à venir s'insérer à l'intérieur des saignées 15 de la carnette. Avantageusement, les saignées ou profils 15 de la carnette présentent une largeur inférieure à la largeur des nervures 23 de manière à ce que les nervures 23 se déforment plastiquement contre les bords des saignées 15. De préférence, la largeur des saignées 15 est décroissante à partir de l'extrémité supérieure du col, de sorte qu'au niveau de l'extrémité supérieure du col, la largeur des saignées est supérieure à la largeur des nervures, et qu'à rextrémité inférieure des saignées, la largeur est inférieure à la largeur des nervures 23. Ainsi, les nervures 23 peuvent être insérées en force dans les saignées 15. Comme on peut le voir sur la figure 3b, il est avantageux que les bords obliques des saignées 15 forment un profil de harponnage 16 par exemple situé à l'extrémité inférieure des saignées 15. On peut également imaginer des formes de saignées avec un ou plusieurs profils de harponnage formé(s) sur les bords des saignées autre part qu'à leur extrémité inférieure. Alors que les nervures sont déformées radialement dans le mode de réalisation des figures la et lb, ici, les nervures sont déformées tangentiellement par les bords des saignées 15. Avec de tels saignées verticales 15, l'accrochage de la jupe 30 est à la fois bloqué verticalement mais également en rotation. En effet, il est impossible de retirer l'organe de fixation du col du fait de la présence des profils de harponnage 16 formés par la carnette 11. On assure ainsi une fonction solide et irréversible de la bague sur le col.Reference will now be made to FIGS. 2, 3a and 3b to explain a second embodiment according to the invention. In this embodiment, the ring 20 is also formed with ribs 23 which extend vertically over part of the height of the skirt. As in the previous embodiment, these ribs 23 cooperate with the bag 11 of the neck 10 of the container. According to the invention, several vertical grooves can be made in the camette 11. These profiles or grooves can extend from top to bottom of the carnette, so that the carnette is interrupted at this location, but the bleeding can also be spread only on one part of the height of the sock from its upper end, leaving the lower end of the sash intact. In the embodiment used to illustrate the present invention, the groove 15 extends right through the carnette. In FIG. 3a, it can be seen that the camette 11 is formed with two grooves of this type. Of course, one can provide more than two grooves of this type, for example distributed regularly over the periphery of the neck. According to the invention, the ribs 23 formed on the skirt 20, which are also two in number, are adapted to be inserted inside the grooves 15 of the carnette. Advantageously, the grooves or profiles 15 of the carnette have a width less than the width of the ribs 23 so that the ribs 23 deform plastically against the edges of the grooves 15. Preferably, the width of the grooves 15 decreases from from the upper end of the neck, so that at the upper end of the neck, the width of the grooves is greater than the width of the ribs, and that at the lower end of the grooves, the width is less than the width ribs 23. Thus, the ribs 23 can be forcibly inserted into the grooves 15. As can be seen in FIG. 3b, it is advantageous that the oblique edges of the grooves 15 form a harpooning profile 16, for example located at the 'lower end of the grooves 15. One can also imagine forms of grooves with one or more harpoon profiles formed (s) on the edges of the grooves other than their lower end. While the ribs are deformed radially in the embodiment of Figures la and lb, here, the ribs are deformed tangentially by the edges of the grooves 15. With such vertical grooves 15, the attachment of the skirt 30 is both blocked vertically but also in rotation. Indeed, it is impossible to remove the neck fixing member due to the presence of the harpooning profiles 16 formed by the carnette 11. This thus ensures a solid and irreversible function of the ring on the neck.
Il est à noter que la frette d'habillage 3 peut également être prémontée avant le montage de la bague sur le col, étant donné que la déformation des nervures n'occasionne aucune déformation de la paroi externe de la jupe 20.It should be noted that the covering hoop 3 can also be pre-assembled before mounting the ring on the neck, since the deformation of the ribs does not cause any deformation of the external wall of the skirt 20.
La troisième forme de réalisation représentée sur les figures 4 et 5 est une variante du premier mode de réalisation des figures la et lb. La jupe 20 est ici formée avec des évidements internes longitudinaux 26 qui s'étendent sur la hauteur de la jupe. Ces évidements 26 sont internes puisqu'ils ne débouchent ni sur la paroi interne 202 ni sur la paroi externe 201. Ils s'étendent à partir de l'extrémité inférieure 203 de la jupe 20 vers le haut et se présentent de ce fait sous la forme de trous borgnes débouchant sur l'extrémité inférieure 203 de la jupe et s'étendant vers le haut axialement dans l'épaisseur de la paroi de la jupe sans interférer avec la paroi interne et la paroi externe de la jupe. Ces évidements peuvent par exemple être réalisés à l'aide d'une broche qui pénètre dans le moule à partir de l'extrémité inférieure de la jupe.The third embodiment shown in Figures 4 and 5 is a variant of the first embodiment of Figures la and lb. The skirt 20 is here formed with longitudinal internal recesses 26 which extend over the height of the skirt. These recesses 26 are internal since they do not open either on the internal wall 202 or on the external wall 201. They extend from the lower end 203 of the skirt 20 upwards and are therefore presented under the form of blind holes opening onto the lower end 203 of the skirt and extending upward axially in the thickness of the wall of the skirt without interfering with the internal wall and the external wall of the skirt. These recesses can for example be produced using a pin which penetrates into the mold from the lower end of the skirt.
Comme on peut le voir sur la figure 5, les évidements 26 sont séparés de la paroi externe 201 par des segments de paroi 28 et de la paroi interne 202 par d'autres segments de paroi 27 sur lesquels sont formées les nervures internes longitudinales 23. Par conséquent, un évidement 26 est toujours associé à une nervure 23, et la nervure est située radialement devant l'évidement. En d'autres termes, les évidements 26 sont situés juste derrière les nervures 23 si l'on part du centre de l'organe de fixation, de sorte que les nervures peuvent se déformer radialement vers l'extérieur dans les évidements, notamment lors de leur montage sur le col du récipient. Au cours de cette déformation des nervures 23, seuls les segments de paroi 27 sont déformés alors que les segments de paroi 28 ne subissent aucune déformation. De ce fait, la paroi externe 201 de la jupe 20 ne subit pas de déformation lors du montage de la bague sur un col de récipient. Il est ainsi possible de monter une frette 3 sur la bague avant montage de la bague sur le col de récipient. La frette 3, qui présente un corps sensiblement cylindrique 30 avec une paroi externe 32 et une paroi interne 33 peut venir en contact de la paroi externe 201 de la jupe sur toute sa périphérie comme on peut le voir sur la figure 5. L'organe de fixation peut être monté sur un col avec la frette 3 montée sur la bague 2 comme représenté sur la figure 4. Avantageusement, les évidements sont plus larges que les nervures.As can be seen in FIG. 5, the recesses 26 are separated from the external wall 201 by wall segments 28 and from the internal wall 202 by other wall segments 27 on which the longitudinal internal ribs 23 are formed. Consequently, a recess 26 is always associated with a rib 23, and the rib is located radially in front of the recess. In other words, the recesses 26 are located just behind the ribs 23 if one starts from the center of the fixing member, so that the ribs can deform radially outwards in the recesses, in particular during mounting them on the container neck. During this deformation of the ribs 23, only the wall segments 27 are deformed while the wall segments 28 do not undergo any deformation. Therefore, the external wall 201 of the skirt 20 does not undergo deformation during mounting of the ring on a container neck. It is thus possible to mount a hoop 3 on the ring before mounting the ring on the container neck. The hoop 3, which has a substantially cylindrical body 30 with an external wall 32 and an internal wall 33 can come into contact with the external wall 201 of the skirt over its entire periphery as can be seen in FIG. 5. The member fixing can be mounted on a neck with the hoop 3 mounted on the ring 2 as shown in Figure 4. Advantageously, the recesses are wider than the ribs.
Les nervures 23 peuvent par exemple être déformées radialement vers l'intérieur dans les évidements 26 au niveau de la paroi 13 du col 10 en venant se conformer au profil de l'épaulement inférieur de l'épaississement 11. Il est à noter qu'avec ces nervures longitudinales 23 qui s'étendent avantageusement sur la totalité de la hauteur de la jupe, il est possible de réaliser une fixation sur un col dont la partie épaissie 11 peut varier en hauteur. Ceci n'était pas le cas avec les dispositifs de l'art antérieur utilisant des dents ou des cordons d'encliquetage destinés à venir se loger sous cet épaulement.The ribs 23 can for example be deformed radially inwards in the recesses 26 at the wall 13 of the neck 10, coming to conform to the profile of the lower shoulder of the thickening 11. It should be noted that with these longitudinal ribs 23 which advantageously extend over the entire height of the skirt, it is possible to make a fixing on a neck whose thickened part 11 can vary in height. This was not the case with the devices of the prior art using teeth or snap cords intended to be housed under this shoulder.
Dans ces modes de réalisation, on se sert de nervures longitudinales ou verticales formées sur la paroi interne de la jupe : ces nervures sont plastiquement déformables, par exemple par fluage, sur la paroi externe sensiblement cylindrique du col qui est avantageusement pourvu de profils d'accrochage. Le col n'est pas forcément pourvu d'une camette. La déformation des nervures peut être radiale ou encore tangentielle. In these embodiments, longitudinal or vertical ribs formed on the internal wall of the skirt are used: these ribs are plastically deformable, for example by creep, on the substantially cylindrical external wall of the neck which is advantageously provided with profiles of hanging. The collar is not necessarily provided with a camette. The deformation of the ribs can be radial or even tangential.
