Description

La présente invention concerne un dispositif de produit fluide comprenant un récipient, un organe de distribution tel qu'une pompe ou une valve et des moyens de fixation pour fixer l'organe de distribution sur le récipient. Le récipient définit en général un réservoir destiné à contenir du produit fluide à distribuer par l'organe de distribution. Le récipient est formé avec un col définissant une ouverture dans laquelle l'organe de distribution est fixé à l'aide des moyens de fixation qui comprennent en général des moyens de réception souvent par encliquetage pour l'organe de distribution. En outre, les moyens de fixation comprennent des moyens d'accrochage sur le col du récipient.The present invention relates to a fluid product device comprising a container, a dispensing member such as a pump or a valve and fixing means for fixing the dispenser member on the container. The container generally defines a reservoir intended to contain fluid product to distribute by the distributor. The container is formed with a collar defining an opening in which the dispenser member is secured using fastening means which generally comprise receiving means often snap-fastening for the dispensing member. In addition, the means of fasteners comprise hooking means on the neck of the container.

De manière conventionnelle, les moyens de fixation comprennent souvent une pièce de fixation définissant une jupe sensiblement cylindrique qui s'étend autour du col. Il est également classique de former le col avec un renfort qui forme un rebord rentrant vers l'intérieur pour rejoindre une partie inférieure plus fine du col qui se raccorde au réservoir par un épaulement.Conventionally, the fixing means comprise often a fastener defining a substantially cylindrical skirt which extends around the neck. It is also classic to train the collar with a reinforcement which forms an inward rim to join a lower part finer neck that connects to the tank by a shoulder.

Une technique de fixation bien connue est de se servir de la jupe pour réaliser une fixation en dessous du renfort c'est à dire au niveau du rebord. On connaít plusieurs solutions techniques de ce type. On peut notamment former la jupe avec des pattes terminées par des têtes d'encliquetage destinées à venir en prise en dessous du renfort contre le rebord. Pour bloquer les pattes en position, on utilise en général une frette qui vient recouvrir la jupe. Une autre technique prévoit de réaliser la jupe de manière continue et de réaliser intérieurement un cordon d'encliquetage qui vient se loger en dessous du renfort.A well known fastening technique is to use the skirt for make a fixation below the reinforcement that is to say at the edge. We know several technical solutions of this type. In particular, we can train skirt with tabs terminated by snap-in heads intended to come into taken below the reinforcement against the rim. To lock the legs in position, we generally use a band that comes to cover the skirt. Another technique plans to carry out the skirt in a continuous way and to realize internally a snap cord which is housed below the reinforcement.

Dans la technique de fixation par pattes et têtes d'encliquetage, il est nécessaire d'utiliser une frette de blocage. Par conséquent, il n'est pas possible de monter la frette avant de monter la jupe sur un col de récipient. Dans l'autre technique d'encliquetage par jupe continue et cordon intérieur, il arrive que la fixation ne soit pas parfaitement sûre et il est ainsi possible de retirer l'organe de distribution manuellement en tirant dessus. On n'assure donc pas une parfaite sécurité de premier usage à l'utilisateur.In the fastening technique with tabs and snap heads, it is necessary to use a locking ferrule. Therefore, it is not possible to mount the hoop before mounting the skirt on a container neck. In the other technique of snap-fitting by continuous skirt and inner cord, it happens that the fixation is not perfectly safe and it is thus possible to remove the dispensing manually by pulling on it. We do not ensure a perfect security of first use to the user.

Le document US-4 984 702 divulgue un distributeur de produit fluide comportant des moyens de fixation 50 pour fixer un organe de distribution 80 sur un col 12 du récipient 10. Les moyens de fixation 50 comprennent une bague 28 disposée autour du col 12 du récipient 10, ainsi qu'un élément annulaire 32 en contact de la paroi externe du col 12, la bague 28 étant en prise à l'intérieur d'un fût 24 de manière à solliciter l'élément annulaire 32 contre la paroi externe du col 12. US-4,984,702 discloses a fluid dispenser comprising fastening means 50 for fixing a dispensing member 80 on a neck 12 of the container 10. The fastening means 50 comprise a ring 28 disposed around the neck 12 of the container 10, and an annular element 32 in contact with the outer wall of the neck 12, the ring 28 being engaged inside a barrel 24 of in such a way as to urge the annular element 32 against the external wall of the neck 12.

La présente invention a pour but de remédier aux inconvénients précités de l'art antérieur en définissant un distributeur dans lequel les moyens de fixation sont parfaitement sûrs tout en se passant d'une frette de blocage. Par conséquent, si une frette est utilisée, il s'agirait d'une simple frette d'habillage qui pourra être préalablement montée sur la jupe même avant le montage sur le col du récipient.The present invention aims to overcome the aforementioned drawbacks of the prior art by defining a distributor in which the fixing means are perfectly safe while passing a blocking fret. Therefore, if a fret is used, it would be a simple fret dress that can be previously mounted on the skirt even before mounting on the neck of the container.

Pour ce faire, la présente invention prévoit que les moyens dé fixation comprennent une bague disposée autour du col du récipient, ainsi qu'un élément annulaire en contact de la paroi externe du col, la bague étant en prise à l'intérieur d'un fût formé par la jupe ou la frette de manière à solliciter l'élément annulaire contre la paroi externe du col. On utilise donc le déplacement relatif de la bague pour solliciter, voire presser, l'élément annulaire contre la paroi externe du col. Dans le cas où l'élément annulaire est fortement pressé par coincement par la bague, cet élément annulaire peut servir d'élément d'étanchéité au même titre qu'un joint de col. C'est précisément la prise de la bague à l'intérieur du fût qui permet le déplacement relatif entre ces deux pièces pour amener l'élément annulaire en contact de la paroi externe du col.For this purpose, the present invention provides that the fixing means comprise a ring disposed around the neck of the container, as well as an element annular contact with the outer wall of the neck, the ring being engaged with the inside of a barrel formed by the skirt or the hoop so as to solicit the element ring against the outer wall of the neck. So we use the relative displacement of the ring to urge or even press the annular element against the outer wall of the collar. In the case where the annular element is strongly pressed by jamming by the ring, this annular element can serve as a sealing element to the same as a neck seal. It is precisely the taking of the ring inside the barrel which allows relative movement between these two pieces to bring the element ring in contact with the outer wall of the neck.

L'élément annulaire peut faire partie de la jupe ou de la bague sous la forme d'une partie déformable sollicitée par la bague ou la jupe en contact de la paroi externe du col. Lorsque la jupe réalise la partie déformable, c'est la bague qui servira de came pour solliciter cette partie déformable contre la paroi externe du col, et lorsque c'est la bague qui forme la partie déformable, c'est la jupe qui sollicitera la bague contre la paroi externe du col. La sollicitation de la jupe ou de la bague peut se faire par un système de came.The annular element can be part of the skirt or the ring under the shape of a deformable part urged by the ring or the skirt in contact with the outer wall of the neck. When the skirt realizes the deformable part, it is the ring which will serve as a cam to urge this deformable part against the outer wall neck, and when it is the ring that forms the deformable part, it is the skirt that will urge the ring against the outer wall of the neck. The solicitation of the skirt or of the ring can be done by a cam system.

En variante, l'élément annulaire peut être une pièce déformable séparée par exemple sous la forme d'un joint torique disposée entre la jupe, la bague et la paroi externe du col.Alternatively, the annular element may be a separate deformable part for example in the form of an O-ring disposed between the skirt, the ring and the outer wall of the neck.

La prise de la bague à l'intérieur de la jupe ou de la frette peut se faire par diverses techniques, et notamment par vissage, serrage, encliquetage ou harponnage. Cette dernière technique permet en effet une prise irréversible, de sorte que la fixation est définitive. The taking of the ring inside the skirt or the hoop can be done by various techniques, in particular by screwing, tightening, snapping or harpooning. This last technique makes it possible to take irreversible so that the fixation is final.

Selon un mode de réalisation, le col comprend des moyens de blocage en rotation pour bloquer la bague en rotation autour du col. Le blocage de la bague en rotation est notamment nécessaire lorsque la prise entre la bague et la jupe est réalisée par vissage. Il est en effet nécessaire de bloquer la bague sur le col pour pouvoir visser la jupe sur la bague sans l'entraíner en rotation.According to one embodiment, the collar comprises locking means in rotation to lock the rotating ring around the neck. The blocking of the ring in particular when the catch between the ring and the skirt is made by screwing. It is indeed necessary to lock the ring on the neck for can screw the skirt on the ring without causing it to rotate.

En revanche, lorsque la prise entre la bague et la jupe est réalisée par harponnage, il est nécessaire de bloquer la bague en translation sur le col afin de pouvoir emmancher la jupe sur la bague. A cet effet, la bague peut prendre appui avec son extrémité inférieure sur le récipient. Plus précisément, la bague prend appui sur le récipient au niveau où le col rejoint le corps du réservoir.On the other hand, when the catch between the ring and the skirt is made by harpooning, it is necessary to lock the ring in translation on the neck in order to to be able to put the skirt on the ring. For this purpose, the ring can be supported with its lower end on the container. More precisely, the ring takes support on the container at the level where the neck joins the body of the tank.

Selon une autre caractéristique, la jupe peut être pourvue d'un habillage en contact de la jupe au niveau de la bague. Etant donné que la paroi externe de la jupe n'est pas déformée lors du déplacement de la bague, il est possible de monter la frette d'habillage sur la jupe même avant son montage sur le col d'un récipient.According to another characteristic, the skirt may be provided with a covering in contact with the skirt at the level of the ring. Since the outer wall of the skirt is not deformed when moving the ring, it is possible to mount the trim band on the skirt even before it is mounted on the collar of a container.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif plusieurs modes de réalisation de l'invention.The invention will now be further described with reference to accompanying drawings giving by way of non-limiting example several modes of embodiment of the invention.

Ces moyens de fixation comprennent une pièce de fixation 3 définissant un logement de réception par encliquetage 33 dans lequel une collerette 22 formée par le corps 20 de la pompe 2 est encliquetée. Le logement d'encliquetage 33 est formé avec une ouverture centrale à travers laquelle s'étend la tige d'actionnement 23 de la pompe 2. Un poussoir 24 éventuellement pourvu d'un gicleur 25 est monté sur la tige d'actionnement 23. A l'autre extrémité du corps de pompe 20, est prévu un manchon d'entrée 21 sur lequel peut être éventuellement adapté un tube plongeur qui s'étend jusqu'au fond du réservoir du récipient 1. Le logement d'encliquetage 33 s'étend ensuite vers l'extérieur pour définir une collerette annulaire 32 qui vient s'appuyer sur l'extrémité supérieure du col 10. La pièce de fixation 3 se prolonge sur la périphérie extérieure de la collerette radiale 32 vers le bas par une jupe 30 qui vient entourer le col 10. Pour des raisons esthétiques, la jupe 30 peut s'étendre vers le bas pratiquement jusqu'au contact du récipient 1.In all the embodiments shown in the figures, the fluid dispenser is only partially represented, since the tank is not visible. It is represented only the upper part of the container which forms a neck 10 forming an opening 15 in which extends an organ of distribution, here a pump 2. The dispenser could very well have been a valve. The neck 10 of the container 1 defines an outer peripheral wall 13. The pump 2 is fixed in the opening 15 of the neck 10 by means of fixing means 3. These fixing means comprise a fastener 3 defining a snap receiving housing 33 in which a flange 22 formed by the body 20 of the pump 2 is snapped. The detent housing 33 is formed with a central opening through which the stem extends 23 of the pump 2. A pusher 24 optionally provided with a nozzle 25 is mounted on the actuating rod 23. At the other end of the body 20, there is provided an inlet sleeve 21 on which can be possibly adapted a dip tube that extends to the bottom of the tank of the container 1. The detent housing 33 then extends outwardly to define an annular flange 32 which comes to rest on the end upper part of the neck 10. The attachment piece 3 extends on the periphery outer of the radial flange 32 downwards by a skirt 30 which surrounds the collar 10. For aesthetic reasons, the skirt 30 can extend downwards almost to the point of contact with the container 1.

Jusque là, il s'agit d'une conception tout à fait classique pour un distributeur de produit fluide. So far, this is a quite classic design for a fluid dispenser.

Dans tous les modes de réalisation, le col 10 du récipient 1 est formé avec un renfort 11 qui fait saillie vers l'extérieur. Ce renfort 11 forme un rebord rentrant qui permet de rejoindre la partie inférieure plus fine du col 10 qui se raccorde au réservoir en formant un épaulement 16. La paroi périphérique externe 13 du col 10 est formée par la surface externe du renfort 11 ainsi que du rebord 12.In all embodiments, the neck 10 of the container 1 is formed with a reinforcement 11 which protrudes outwards. This reinforcement 11 forms a rim returning to join the lower part of the fin pass 10 which is connects to the reservoir forming a shoulder 16. The peripheral wall 13 of the neck 10 is formed by the outer surface of the reinforcement 11 and the edge 12.

Selon l'invention, les moyens de fixation comprennent en plus de la pièce de fixation 3, une bague 4 qui s'étend également autour du col 10 à l'intérieur de la jupe 30. La bague 4 est en prise à l'intérieur de la jupe 30, soit par vissage soit par harponnage.According to the invention, the fixing means comprise in addition to the piece 3, a ring 4 which also extends around the neck 10 inside of the skirt 30. The ring 4 is engaged inside the skirt 30, either by screwing or by harpooning.

Selon l'invention, les moyens de fixation comprennent, en plus de la pièce de fixation 3 et de la bague 4, un élément annulaire qui est en contact avec la paroi périphérique externe 13 du col 10. En d'autres termes, l'élément annulaire est en contact soit du renfort 11, soit du rebord 12.According to the invention, the fixing means comprise, in addition to the piece 3 and the ring 4, an annular element which is in contact with the outer peripheral wall 13 of the neck 10. In other words, the annular element is in contact with either the reinforcement 11 or the flange 12.

Selon l'invention, la bague 4 en prise dans la jupe 30 sollicite l'élément annulaire en contact contre la paroi externe du col 10. Il s'agit là du principe de base de la présente invention.According to the invention, the ring 4 engaged in the skirt 30 solicits the element ring in contact with the outer wall of the neck 10. This is the principle of basis of the present invention.

Nous nous référerons maintenant plus particulièrement aux figures 1a et 1b pour expliquer le premier mode de réalisation de l'invention. Dans ce mode de réalisation, la bague 4 est en prise de harponnage dans la jupe 30. Comme on peut le voir plus clairement sur la figure 1b, la bague 4 est formée avec un corps 40 surmonté d'une tête 41.We will now refer more particularly to Figures 1a and 1b to explain the first embodiment of the invention. In this mode embodiment, the ring 4 is in spear pattern in the skirt 30. As we can see it more clearly in FIG. 1b, the ring 4 is formed with a body 40 surmounted by a head 41.

Des reliefs de harponnage 44 sont formés sur la paroi externe du corps 40 de la bague 4 pour venir mordre dans la paroi interne de 1a jupe 30. L'orientation des reliefs de harponnage 44 autorise un déplacement unidirectionnel de la bague 4 dans la jupe 30, à savoir vers le haut. Il est en effet impossible de faire redescendre la bague 4 dans la jupe 30.Harpooning reliefs 44 are formed on the outer wall of the body 40 of the ring 4 to bite into the inner wall of the skirt 30. The orientation harpooning reliefs 44 allows a unidirectional movement of the ring 4 in the skirt 30, namely upwards. It is impossible to do go down the ring 4 in the skirt 30.

L'élément annulaire est formé ici par une partie déformable 36 définie par la jupe 30. La partie déformable 36 s'étend tout autour du col 10 ou seulement par segment ou sous la forme de pattes. La partie déformable 36 comprend un corps 361 qui se termine par une tête 360. A l'état initial (non représenté) la bague 4 n'est engagée que partiellement dans la jupe 30 de sorte que la partie déformable 36 peut s'étendre le long de la jupe 30 dans l'alignement de la bague 4. La tête 41 de la bague 4 se trouve alors juste en dessous de la tête 360 de la partie déformable 36. Dans cette configuration, il est alors possible d'engager les moyens de fixation 3 sur le col 10 du récipient 1 sans difficulté, puisque la partie déformable 36 ne fait pas saillie vers l'intérieur. Dès que l'extrémité inférieure 46 de la bague 4 vient en contact du récipient 1, une pression supplémentaire sur les moyens de fixation 3 amène la bague 4 à se déplacer dans la jupe 30 en remontant à l'intérieur d'elle. La tête 41 de la bague 4 est formée avec une surface de came inclinée 42 qui permet à la tête 41 de s'engager en dessous de la tête 360 de la partie déformable 36. L'engagement de la tête 41 entre la tête 360 et la jupe 30 a pour effet de déplacer la tête 360 vers l'intérieur, c'est à dire sous le renfort 11, en dessous du rebord 12. En continuant à appuyer sur les moyens de fixation 3, la bague 4 continue à s'engager à l'intérieur de la jupe 30 jusqu'à ce que sa tête 41 vienne s'encliqueter sur la tête 360 de la partie déformable 36 au niveau d'un cran mutuel 43. La bague 4 est alors engagée au maximum à l'intérieur de la jupe 30, ce qui est représenté que la figure 1a et en vue agrandie sur la figure 1b. Dans cette position, la tête 360 est sollicitée vers l'intérieur, mais également une partie du corps 361 qui est disposée en biais de sorte que sa paroi externe vient en contact appuyé contre le rebord 12 au niveau de sa jonction avec le renfort 11. Lorsque la partie déformable 36 est formée de manière continue tout autour du col, le contact de la partie déformable 36 avec le bord inférieur du renfort 11 s'effectue de manière continue sur toute la périphérie du col, ce qui réalise en même temps une fixation solide et une étanchéité efficace. Il est à noter que dans ce mode de réalisation (partie déformable continue), il est possible de se passer d'un joint de col interposé entre la bride 32 et l'extrémité supérieure du col 10.The annular element is formed here by a deformable part 36 defined by the skirt 30. The deformable portion 36 extends around the neck 10 or only by segment or in the form of legs. The deformable portion 36 comprises a body 361 which ends with a head 360. In the initial state (not shown) the ring 4 is engaged only partially in the skirt 30 so that the part deformable 36 may extend along the skirt 30 in the alignment of the ring 4. The head 41 of the ring 4 is then just below the head 360 of the deformable part 36. In this configuration, it is then possible to engage the fastening means 3 on the neck 10 of the container 1 without difficulty, since the part deformable 36 does not project inwards. As soon as the lower end 46 of the ring 4 comes into contact with the container 1, an additional pressure on the fixing means 3 causes the ring 4 to move in the skirt 30 in going up inside her. The head 41 of the ring 4 is formed with a inclined cam surface 42 which allows the head 41 to engage below the head 360 of the deformable portion 36. The engagement of the head 41 between the head 360 and the skirt 30 has the effect of moving the head 360 inwards, ie under the reinforcement 11, below the rim 12. By continuing to press the means 3, the ring 4 continues to engage inside the skirt 30 until that its head 41 comes to snap on the head 360 of the deformable portion 36 to level of a mutual notch 43. The ring 4 is then engaged to the maximum at the inside of the skirt 30, which is shown as FIG. 1a and in enlarged view in Figure 1b. In this position, the head 360 is biased inward, but also a part of the body 361 which is arranged diagonally so that its wall outer edge comes into contact against the flange 12 at its junction with the reinforcement 11. When the deformable part 36 is formed continuously all around the neck, the contact of the deformable portion 36 with the lower edge of the reinforcement 11 is carried out continuously along the entire periphery of the neck, which at the same time achieves a solid fixation and effective sealing. He is at note that in this embodiment (continuous deformable part), it is possible to do without a collar joint interposed between the flange 32 and the end upper collar 10.

Il est à noter que dans ce mode de réalisation, on peut se passer des profils de harponnage 44, étant donné que la tête 41 est encliquetée sur la tête 360. Il est de ce seul fait impossible de déplacer la bague 4 en sens inverse de manière à l'extraire de la jupe 30. Les reliefs de harponnage ne sont que des moyens supplémentaires pour améliorer l'accrochage de la bague 4 à l'intérieur de la jupe 30.It should be noted that in this embodiment, one can do without profiles 44, since the head 41 is snapped onto the head 360. It is this alone makes it impossible to move the ring 4 in the opposite direction so as to to extract it from the skirt 30. The harpooning reliefs are only means of additional to improve the attachment of the ring 4 inside the skirt 30.

Il est encore à noter que les moyens de fixation 3 sont recouverts par une frette d'habillage 5 qui se présente sous la forme d'un corps cylindrique 50 terminé à son extrémité supérieure par un rabat rentrant 51 qui vient en appui sur l'extrémité de la douille 31. Le corps cylindrique 50 de la frette d'habillage 5 est en contact de la jupe 30 au niveau de la bague 4. On peut remarquer que le déplacement de la bague 4 à l'intérieur de la jupe 30 n'entraíne pas une déformation radiale vers l'extérieur de la jupe 30, comme c'est le cas avec les techniques de fixation de l'art antérieur décrites ci-dessus. On peut donc monter l'habillage 5 sur les moyens de fixation 3 avant de monter les moyens de fixation sur le col d'un récipient. On peut donc livrer l'ensemble constitué de la bague et des moyens de fixation recouverts par l'habillage 5 à l'état monté. Il ne reste ensuite plus qu'à remplir le récipient et à monter d'une pièce les moyens de fixation avec la pompe et l'habillage 5.It should also be noted that the fixing means 3 are covered by a trim ring 5 which is in the form of a cylindrical body 50 finished at its upper end by a reentrant flap 51 which comes to bear on the end of the sleeve 31. The cylindrical body 50 of the trim band 5 is in contact with the skirt 30 at the level of the ring 4. It may be noted that the displacement of the ring 4 inside the skirt 30 does not cause a radial deformation towards the outside of the skirt 30, as is the case with the prior art fixation techniques described above. So we can ride the covering 5 on the fastening means 3 before mounting the fastening means on the neck of a container. We can therefore deliver the set consisting of the ring and fixing means covered by the casing 5 in the assembled state. It remains then more than to fill the container and to mount in one piece the means of fastening with pump and casing 5.

On se référera maintenant aux figures 2 et 3 pour décrire un second mode de réalisation de l'invention. Dans ce mode de réalisation, les moyens de fixation 3 forment également un logement de réception par encliquetage 33 pour le corps 20 de la pompe 2 ainsi qu'une jupe 30 qui s'étend sur l'extérieur du col 10 formée avec un renfort 11 et un rebord rentrant 12. Là aussi, les moyens de fixation comprennent une bague 4 en prise à l'intérieur de la jupe 30 ainsi qu'un élément annulaire 6 interposé entre le bague 4 et la jupe 30.Referring now to Figures 2 and 3 to describe a second mode embodiment of the invention. In this embodiment, the fixing means 3 also form a snap receiving housing 33 for the body 20 of the pump 2 and a skirt 30 which extends on the outside of the neck 10 formed with a reinforcement 11 and a return flange 12. Here again, the fastening means comprise a ring 4 engaged within the skirt 30 and an element annular 6 interposed between the ring 4 and the skirt 30.

Dans ce mode de réalisation, la prise entre la bague 4 et 1a jupe 30 est une prise filetée de sorte que la bague 4 est vissée à l'intérieur de la jupe 30. L'élément annulaire 6 se présente sous la forme d'une pièce déformable séparée disposée entre la bague 4, la jupe 30 et la paroi externe 13 du col 10. Plus précisément, l'élément annulaire 6, qui joue ici le rôle de joint de fixation et d'étanchéité, est comprimé entre l'extrémité supérieure de la bague 4 et la jupe 30 de manière à être sollicité sous contrainte contre la paroi externe 13 du col 10 où il forme un joint d'étanchéité. L'élément annulaire 6 est logé dans un évidement formé partiellement par la jupe 30 et dans lequel l'extrémité supérieure de la bague 4 pénètre pour réduire le volume du logement et ainsi comprimer l'élément annulaire qui est inséré dans ce logement. On comprend aisément que le vissage de la bague 4 dans la jupe 30 a pour effet de comprimer l'élément annulaire 3 qui est ainsi sollicité fortement contre la paroi externe 13 du col 10.In this embodiment, the engagement between the ring 4 and the skirt 30 is a threaded socket so that the ring 4 is screwed inside the skirt 30. The annular element 6 is in the form of a separate deformable part disposed between the ring 4, the skirt 30 and the outer wall 13 of the neck 10. More precisely, the annular element 6, which acts here as a fixing joint and seal, is compressed between the upper end of the ring 4 and the skirt 30 so as to be urged under stress against the outer wall 13 of the neck 10 where it forms a seal. The annular element 6 is housed in a recess partially formed by the skirt 30 and in which the end upper ring 4 penetrates to reduce the volume of the housing and so compress the annular element that is inserted in this housing. We understand easily that the screwing of the ring 4 in the skirt 30 has the effect of compressing the annular element 3 which is thus strongly urged against the outer wall 13 of the neck 10.

A l'état initial, il suffit que la bague 4 ne sollicite pas l'élément annulaire 6 de sorte qu'il est possible d'engager les moyens de fixation 3 sur le col d'un récipient sans difficultés. Ensuite, il suffit de visser la jupe 30 sur la bague 4 pour faire remonter la bague 4 à l'intérieur de la jupe 30 et ainsi comprimer l'élément annulaire 6. Pour cela, il est nécessaire de fixer en rotation la bague 4 sur le col 10. A cet effet, le col 10 forme des moyens de blocage sous la forme de deux nervures 14 qui s'étendent sous le renfort 11 du col encore plus en saillie vers l'extérieur. La bague 4 présente deux échancrures profondes dans lesquelles sont engagés les deux nervures 14. Les échancrures de la bague 4 s'étendent profondément pour ne laisser subsister qu'un colleret continu 46 qui est positionné au-dessus des nervures 14 comme on peut le voir sur la figure 2. De cette manière, la bague 4 est bloquée en rotation autour du col 10. La bague 30 peut alors être vissée sur la bague sans risque de l'entraíner en rotation.In the initial state, it suffices that the ring 4 does not urge the annular element 6 so that it is possible to engage the fastening means 3 on the neck of a container without difficulties. Then, just screw the skirt 30 on the ring 4 to raise the ring 4 inside the skirt 30 and thus compress the element 6. To do this, it is necessary to fix in rotation the ring 4 on the neck 10. For this purpose, the neck 10 forms locking means in the form of two ribs 14 which extend under the reinforcement 11 of the collar even more protruding towards outside. The ring 4 has two deep indentations in which are engaged the two ribs 14. The notches of the ring 4 extend deeply to leave only a continuous glue 46 that is positioned above the ribs 14 as can be seen in FIG. this way, the ring 4 is locked in rotation around the neck 10. The ring 30 can then be screwed on the ring without risk of causing it to rotate.

Dans ce mode de réalisation, l'appui sur le récipient avec l'extrémité inférieure de la bague est remplacée par son blocage en rotation à l'aide des renforts 14.In this embodiment, pressing on the container with the end the lower part of the ring is replaced by its locking in rotation using the reinforcements 14.

Il est à noter que dans ce mode de réalisation la fixation étanche sur le col est effectué au niveau de la paroi externe cylindrique du col, et non au niveau de son épaulement 12, de sorte que le col peut être réalisé sans carnette 11.It should be noted that in this embodiment the waterproof fastening on the collar at the level of the cylindrical outer wall of the neck, and not at the level of the its shoulder 12, so that the neck can be made without carnette 11.

On se référera maintenant à la figure 4 pour expliquer un autre mode de réalisation. Dans ce mode de réalisation, qui est sensiblement similaire à celui de la figure 2, l'élément annulaire 6 se présente sous la forme d'une pièce déformable séparée 6 interposée entre la bague 4, la jupe 30 et la paroi externe 13 du col 10. L'élément annulaire 6 se présente ici sous la forme d'un joint cylindrique logé dans un évidement formé par la jupe 30 et ouvert sur le bas de manière à ce que la bague 4 puisse pénétrer dans l'évidement de manière à solliciter l'élément 6 en contact pressé étanche contre la surface externe 13 du col 10. On peut voir que l'élément annulaire 6 coopère non seulement avec la paroi cylindrique du renfort 11 mais également avec le rebord 12 de sorte que l'élément annulaire 6 s'étend radialement vers l'intérieur en dessous du renfort 11.Reference is now made to Figure 4 to explain another mode of production. In this embodiment, which is substantially similar to that of 2, the annular element 6 is in the form of a part deformable separated 6 interposed between the ring 4, the skirt 30 and the outer wall 13 of the neck 10. The annular element 6 is here in the form of a seal cylindrical housed in a recess formed by the skirt 30 and open on the bottom of so that the ring 4 can penetrate into the recess so as to urging the element 6 in press-tight contact against the outer surface 13 of the neck 10. It can be seen that the annular element 6 cooperates not only with the wall cylindrical of the reinforcement 11 but also with the rim 12 so that the annular element 6 extends radially inwards below the reinforcement 11.

Dans ce mode de réalisation, la bague 4 n'est pas vissée à l'intérieur de la bague 30 comme dans le mode de réalisation des figures 2 et 3, mais la bague 4 est engagée par une prise harponnée à l'intérieur de la bague 30. A cet effet, la paroi externe de la bague 4 est formée avec des reliefs de harponnage 44 adaptés à mordre dans la paroi interne de la jupe 30. L'extrémité supérieure de la bague 4 est formée avec une surface de came 42 qui est inclinée vers l'intérieur de manière à solliciter l'élément annulaire 6 en dessous du renfort 11 au niveau du rebord 12.In this embodiment, the ring 4 is not screwed inside the ring 30 as in the embodiment of Figures 2 and 3, but the ring 4 is engaged by a catch harpooned inside the ring 30. For this purpose, the outer wall of the ring 4 is formed with adapted harpooning reliefs 44 to bite into the inner wall of the skirt 30. The upper end of the ring 4 is formed with a cam surface 42 which is inclined towards the inside of in order to urge the annular element 6 below the reinforcement 11 at the level of edge 12.

Là encore, le déplacement de la bague 4 à l'intérieur de la jupe 30 se fait par appui sur le récipient 1 au niveau de l'extrémité inférieure 46 de la bague 4. Le mode de déplacement de la bague 4 dans la jupe 30 est donc le même que celui des figures 1a et 1b.Again, the displacement of the ring 4 inside the skirt 30 is by pressing on the container 1 at the lower end 46 of the ring 4. The mode of movement of the ring 4 in the skirt 30 is therefore the same as that of Figures 1a and 1b.

En se référant maintenant à la figure 5, il est représenté un quatrième mode de réalisation, dans lequel la bague 4 forme l'élément annulaire désigné ici sous la référence numérique 48. La bague 4 est formée avec une partie supérieure déformable 48 dont l'extrémité supérieure 49 vient en prise en dessous du renfort 11 au niveau de du rebord 12. Pour solliciter la déformation de la partie 48 de la bague 4 en dessous du renfort 11, la jupe 30 est formée avec une surface de came 38 le long de laquelle l'extrémité supérieure 48 de la bague 4 se déforme à mesure que la bague 4 remonte dans la jupe 30 par appui de son extrémité inférieure 46 contre l'épaulement du récipient 1. Il est ici essentiel que la bague 4 soit dimensionnée de manière précise de sorte que son extrémité supérieure 49 puisse venir en contact sous le rebord 12 alors que son extrémité inférieure 46 est en contact de l'épaulement du récipient.Referring now to Figure 5, there is shown a fourth embodiment, in which the ring 4 forms the annular element designated here under the reference numeral 48. The ring 4 is formed with an upper part deformable 48 whose upper end 49 engages below the reinforcement 11 at the level of edge 12. To request distortion of Part 48 of the ring 4 below the reinforcement 11, the skirt 30 is formed with a cam surface 38 along which the upper end 48 of the ring 4 is deformed to as the ring 4 rises in the skirt 30 by pressing its end lower 46 against the shoulder of the container 1. It is essential here that the ring 4 be dimensioned accurately so that its upper end 49 can come into contact under the rim 12 while its lower end 46 is in contact with the shoulder of the container.

Dans ce mode de réalisation, la prise entre la bague 4 et la jupe 30 est également une prise harponnée irréversible. In this embodiment, the engagement between the ring 4 and the skirt 30 is also an irreversible harpoon catch.

Un cinquième mode de réalisation représente sur la figure 6 se différencie des modes de réalisation précédents en ce que la bague 4 est en prise dans la frette d'habillage 5 par serrage radial. La bague vient se loger entre la frette et la jupe. La bague comprend une came 42 adaptée à se déformer une partie 36 de jupe vers l'intérieur en dessous du renfort, en appui contre le rebord. La bague prend également appui avec son extrémité inférieure sur l'épaulement du récipient pour réaliser son déplacement à l'intérieur de la frette.A fifth embodiment shown in FIG. previous embodiments in that the ring 4 is engaged in the cladding band 5 by radial clamping. The ring is housed between the fret and the skirt. The ring comprises a cam 42 adapted to deform a portion 36 of skirt inward below the reinforcement, resting against the rim. The ring also bears with its lower end on the shoulder of the container for realizing its movement inside the hoop.

Il est à noter que le mode de prise (vissé ou harponné) entre la bague et la jupe 30 peut être interchangé dans chaque mode de réalisation décrit.It should be noted that the setting mode (screwed or harpooned) between the ring and the skirt 30 can be interchanged in each described embodiment.

Le principe de l'invention est de déplacer une bague à l'intérieur de la jupe ou de la frette de manière à solliciter un élément contre la paroi externe du col. Le déplacement de la bague peut se faire par appui sur l'épaulement du récipient ou par blocage en rotation sur le col du récipient. L'élément qui vient en contact de la paroi externe du col peut être aussi bien une partie de la jupe, une partie de la bague ou encore une pièce supplémentaire.The principle of the invention is to move a ring inside the skirt or hoop so as to urge an element against the outer wall of the collar. The displacement of the ring can be done by pressing on the shoulder of the container or by locking in rotation on the neck of the container. The element that comes in contact with the outer wall of the neck can be both a part of the skirt, part of the ring or an additional piece.
