Description

La présente invention concerne les dispositifs de bouchage pour flacons, bouteilles et autres récipients à goulot filetée et, plus particulièrement, un élément de bouchage du type dit "capsule" constitué par un capuchon cylindrique fileté intérieurement destiné à être vissé sur le filetage correspondant du goulot du flacon, ledit capuchon étant solidarisé et parfois réalisé en une seule pièce avec une enveloppe ou un enjoliveur externe conférant à la capsule un aspect esthétique.The present invention relates to closure devices for flasks, bottles and other receptacles with a threaded neck and, more particularly, a closure element of the so-called "capsule" type constituted by an internally threaded cylindrical cap intended to be screwed onto the corresponding thread of the neck. of the bottle, said cap being secured and sometimes made in one piece with an envelope or an external cover giving the capsule an aesthetic appearance.

Lorsque de tels éléments de bouchage à enjoliveur externe non cylindrique sont utilisés sur des flacons non cylindriques destinés à recevoir du parfum, des eaux de toilette, des produits de beauté ou similaires, l'aspect esthétique de l'ensemble constitué par l'élément de bouchage et le flacon a une importance primordiale et il est en particulier nécessaire d'obtenir une mise en coincidence parfaite de la section de l'enjoliveur de l'élément de bouchage et de la section du flacon dans la position de blocage en fin de course du capuchon fileté, ce qui est particulièrement difficile en raison des tolérances de fabrication des filets en verrerie. Le même problème de mise en coincidence peut se trouver posé dans le cas d'un enjoliveur et d'un flacon de sections rondes lorsque des motifs décoratifs ou analogues figurant sur les deux éléments doivent venir en coincidence.When such capping elements with non-cylindrical external cover are used on non-cylindrical bottles intended to receive perfume, eau de toilette, cosmetics or the like, the aesthetic appearance of the assembly constituted by the closure and the bottle is of primary importance and it is in particular necessary to obtain a perfect coincidence of the section of the embellishment of the stopper element and of the section of the bottle in the blocking position at the end of travel threaded cap, which is particularly difficult due to the manufacturing tolerances of glassware nets. The same problem of coincidence can be posed in the case of a hubcap and a bottle of round sections when decorative or similar patterns appearing on the two elements must come into coincidence.

On a tout d'abord pensé à résoudre ce problème en orientant convenablement l'enjoliveur externe par rapport au capuchon pour que, dans la position de blocage en fin de course du filet intérieur du capuchon, les sections soient alignées. Pour parvenir plus facilement à réaliser cet alignement lors de la fabrication de l'élément de bouchage, malgré les tolérances de fabrication en verrerie, on a proposé de monter la partie enjoliveur de l'élément de bouchage sur le capuchon cylindrique fileté intérieurement en vissant tout d'abord sur le goulot dudit flacon le capuchon dont la surface externe est munie de rainures longitudinales, et en emboîtant à force sur ledit capuchon, en lui donnant l'orientation recherchée, ladite partie enjoliveur qui comporte dans ce but un emboîtement interne dont la forme est complémentaire de la surface externe dudit capuchon, Toutefois, après serrages et desserrages répétés de l'élément de bouchage, la position de blocage en fin de course du capuchon intérieur est bien souvent légèrement décalée par suite de l'usure des filets ou du tassement des éléments d'étanchéité et on n'obtient plus dès lors l'orientation correcte de l'élément de bouchage par rapport au corps du flacon.We first thought of solving this problem by properly orienting the outer cover relative to the cap so that, in the locking position at the end of travel of the inner thread of the cap, the sections are aligned. To more easily achieve this alignment during the manufacture of the closure element, despite the manufacturing tolerances in glassware, it has been proposed to mount the trim part of the closure element on the cylindrical cap internally threaded by screwing all first on the neck of said bottle the cap, the external surface of which is provided with longitudinal grooves, and by force fitting on said cap, giving it the desired orientation, said embellishing part which for this purpose has an internal interlocking, the shape is complementary to the external surface of said cap. However, after repeated tightening and loosening of the plugging element, the end-of-travel locking position of the inner cap is very often slightly offset due to wear of the threads or the packing of the sealing elements and the correct orientation of the closure element is no longer obtained with respect to the body of the bottle.

On a aussi proposé un dispositif dans lequel on utilise un encliquetage par emboîtement de l'enjoliveur sur le corps du flacon au voisinage de la position de blocage en fin de course du capuchon. Dans ce cas, l'enjoliveur et le capuchon fileté sont solidaires l'un de l'autre, le bord périphérique de l'enjoliveur formant une lèvre en saillie et la surface supérieure du flacon entourant le goulot portant à sa périphérie une surface d'appui formant gorge dans laquelle la lèvre du bord périphérique de l'enjoliveur doit venir s'em- boiter de manière à aligner les sections. Toutefois, pour que cet emboîtement entre surfaces qui ne sont pas de révolution soit possible, le déplacement longitudinal relatif assurant l'emboîtement de la lèvre et de la gorge doit s'effectuer pendant une rotation d'angle très limité correspondant à une fraction d'environ un huitième de tour de l'élément de bouchage qui doit de ce fait présenter un filet à pas très rapide. En outre, la paroi du flacon entre la gorge d'emboîtement et le goulot fileté doit être déformable élastiquement puisque la surface supérieure de cette paroi est déjà au contact avec le bord de la lèvre de l'enjoliveur alors que celui-ci doit encore, sous l'effet du vissage du capuchon, descendre de la hauteur de l'emboîtement. Il en résulte que le flacon doit être réalisé en matière plastique souple, ce qui interdit les flacons en verre ou autre matière rigide tels qu'habituellement employés dans la parfumerie de luxe. En outre, il est certain que les surfaces de contact entre l'enjoliveur et le corps du flacon doivent être planes, ce qui limite les possibilités esthétiques. De plus, avec ce dispositif de bouchage et à la fin de l'opération de vissage du capuchon limitée par l'arrivée en butée de fin de course du capuchon, il peut subsister un jeu inesthétique entre le corps du flacon et l'enjoliveur du bouchon.A device has also been proposed in which a snap-fit engagement of the hubcap on the body of the bottle is used in the vicinity of the end-of-stroke locking position of the cap. In this case, the hubcap and the threaded cap are integral with each other, the peripheral edge of the hubcap forming a projecting lip and the upper surface of the bottle surrounding the neck carrying at its periphery a surface of support forming a groove in which the lip of the peripheral edge of the hubcap must come together so as to align the sections. However, for this interlocking between surfaces which are not of revolution to be possible, the relative longitudinal displacement ensuring the interlocking of the lip and the groove must be carried out during a very limited angle rotation corresponding to a fraction of about an eighth of a turn from the bou element chage which must therefore have a very fast pitch net. In addition, the wall of the bottle between the nesting groove and the threaded neck must be elastically deformable since the upper surface of this wall is already in contact with the edge of the lip of the hubcap while the latter must still be, under the effect of the cap screwing down from the height of the socket. It follows that the bottle must be made of flexible plastic, which prohibits glass bottles or other rigid material as usually used in luxury perfumery. In addition, it is certain that the contact surfaces between the hubcap and the body of the bottle must be flat, which limits the aesthetic possibilities. In addition, with this closure device and at the end of the cap screwing operation limited by the arrival at the end of the cap limit stop, there can remain an unsightly play between the body of the bottle and the trim of the plug.

Pour remédier à ces inconvénients, la demanderesse a déjà proposé des éléments de bouchage dont l'enjoliveur est, en position de bouchage, toujours orienté correctement par rapport au corps du flacon.To overcome these drawbacks, the applicant has already proposed closure elements, the hubcap of which is, in the closure position, always oriented correctly relative to the body of the bottle.

Dans une première demande de brevet française N° 78 07880 déposée le 17 Mars 1978 le résultat est obtenu en désolidarisant partiellement au déplacement axial, et éventuellement à la rotation, le capuchon fileté et l'enjoliveur. Selon un mode de réalisation l'enjoliveur comporte un emboîtement avec le corps du flacon, emboîtement qui correspond à une orientation angulaire correcte de l'enjoliveur, cet emboîtement s'effectuant par une sollicitation élastique exercée entre le capuchon et l'enjoliveur et s'exerçant sur l'enjoliveur dans la direction de vissage du bouchon.In a first French patent application No. 78 07880 filed on March 17, 1978 the result is obtained by partially separating the axial displacement, and possibly the rotation, the threaded cap and the hubcap. According to one embodiment, the embellishment comprises an interlocking with the body of the bottle, interlocking which corresponds to a correct angular orientation of the embellisher, this interlocking being effected by an elastic stress exerted between the cap and the embellisher and s' working on the hubcap in the direction of screwing the cap.

Dans une deuxième demande de brevet française N° 78 12320 déposée le 26 Avril 1978 le résultat est obtenu en désolidarisant partiellement au déplacement axial le flacon et un élément d'orientation du bouchon fixe à la rotation par rapport au flacon et portant une butée radiale venant coopérer en fin de course de vissage avec une butée radiale solidaire du capuchon. En pratique la butée radiale est comme dans la première demande réalisée sous forme d'un encliquetage à emboîtement longitudinal entre un élément d'orientation sollicité élastiquement dans la direction opposée à la direction de vissage du bouchon et une partie du bouchon qui peut être le capuchon ou l'enjoliveur.In a second French patent application No. 78 12320 filed on April 26, 1978 the result is obtained by partially dissociating the bottle and the axial displacement element for orienting the cap fixed to rotation relative to the bottle and carrying a radial stop coming to cooperate at the end of the screwing stroke with a radial stop secured to the cap. In practice, the radial stop is as in the first request made in the form of a latching with longitudinal interlocking between an orientation element resiliently biased in the direction opposite to the direction of screwing of the plug and a part of the plug which may be the cap. or the hubcap.

Ces deux modes de réalisation donnent satisfaction mais le premier présente l'inconvénient d'aboutir à un bouchon relativement complexe tandis que le second nécessite le montage sur le flacon d'un élément d'orientation monté coulissant élastiquement sur le flacon et qui doit être adapté à chaque forme de flacon pour pouvoir coulisser sans tourner sur celui-ci. En outre la réalisation et l'adaptation sur le flacon d'un élément d'orientation coulissant entraîne des problèmes particuliers en ce qui concerne l'esthétique du flacon.These two embodiments are satisfactory, but the first has the drawback of leading to a relatively complex stopper, while the second requires the mounting on the bottle of an orientation element mounted to slide elastically on the bottle and which must be adapted. to each shape of bottle to be able to slide without turning on it. In addition the production and adaptation on the bottle of a sliding orientation element gives rise to particular problems as regards the aesthetics of the bottle.

La présente invention a pour but de résoudre le problème en utilisant un élément de bouchage du type "capsule" classique comportant seulement une butée radiale susceptible de coopérer avec une butée radiale solidaire du corps du flacon, par exemple des butées radiales résultant d'un encliquetage par emboîtement, en combinaison avec un dispositif de sollicitation à l'encliquetage de l'élément de bouchage et du corps du flacon qui soit éventuellement adaptable sur des flacons de formes quelconques.The object of the present invention is to solve the problem by using a conventional "capsule" type closure element comprising only a radial stop capable of cooperating with a radial stop secured to the body of the bottle, for example radial stops resulting from a snap-fastening. by interlocking, in combination with a snap-on biasing device for the closure element and for the body of the bottle, which may be adaptable to bottles of any shape.

Le résultat est obtenu conformément à l'invention par le fait que le dispositif de sollicitation à l'encliquetage par emboîtement de l'élément de bouchage et du corps du flacon est constitué par une pièce portant le filetage du goulot et sollicitée élastiquement dans la direction de vissage du bouchon avec des moyens limitant la rotation de ladite pièce par rapport au corps du flacon.The result is obtained in accordance with the invention by the fact that the snap-on biasing device for the plugging member and the body of the bottle consists of a part carrying the thread of the neck and elastically biased in the direction screwing the cap with means limiting the rotation of said part relative to the body of the bottle.

3elon un mode de réalisation préférentiel la pièce portant le filetage du goulot est constituée par un manchon fileté extérieurement monté coulissant sur une embase de goulot solidaire du corps du flacon avec guidage longitudinal relatif entre les deux pièces les solidarisant à la rotation et élément élastique agissant entre l'embase de goulot et le manchon pour solliciter ce dernier vers le corps du flacon.3According to a preferred embodiment the part carrying the thread of the neck is constituted by an externally threaded sleeve slidably mounted on a neck base secured to the body of the bottle with relative longitudinal guide between the two parts securing them to the rotation and elastic element acting between the neck base and the sleeve to urge the latter towards the body of the bottle.

La butée radiale solidaire du corps du flacon peut être portée par la surface du corps du flacon avec laquelle vient en contact le bord de la jupe de l'enjoliveur, la butée radiale solidaire du bouchon étant portée par cette jupe ou une surface de l'enjoliveur voisine de cette jupe. La butée radiale solidaire du corps du flacon peut également être portée par la face terminale de l'embase de goulot ou une pièce qui en est solidaire à la rotation, la butée radiale solidaire du bouchon étant située à l'intérieur du capuchon fileté solidaire de l'enjoliveur.The radial stop integral with the body of the bottle can be carried by the surface of the body of the bottle with which the edge of the skirt of the hubcap comes into contact, the radial stop integral with the cap being carried by this skirt or a surface of the hubcap next to this skirt. The radial stop integral with the body of the bottle can also be carried by the end face of the neck base or a part which is integral with rotation, the radial stop integral with the cap being located inside the threaded cap integral with the hubcap.

L'élément élastique peut être constitué par un ressort de compression agissant entre l'embase de goulot ou une bague qui en est solidaire et le manchon fileté ou une collerette interne qui en est solidaire. Du fait que la course du déplacement relatif est limitée à la profondeur de l'emboîtement qui est réduite et à la fraction du pas correspondant à l'angle de symétrie du bouchon ou angle dont il faut faire tourner le bouchon pour ramener sa section en coincidence avec la section du flacon, la course de l'élément élastique est réduite et il peut être réalisés par une rondelle élastique agissant entre les deux éléments. Selon un mode de réalisation, le manchon comporte un élément intérieur solidarisé avec l'embase de goulot et un élément extérieur fileté, les deux éléments étant réunis par un voile mince déformable élastiquement. Dans le cadre de ce mode de réalisation l'élément intérieur peut être engagé à force sur un goulot droit du type à jonc périphérique ou être vissé sur un goulot fileté.The elastic element may be constituted by a compression spring acting between the neck base or a ring which is integral with it and the threaded sleeve or an internal flange which is integral with it. Because the stroke of the relative movement is limited to the depth of the fitting which is reduced and to the fraction of the step corresponding to the angle of symmetry of the plug or angle whose plug must be rotated to bring its section into coincidence with the section of the bottle, the stroke of the elastic element is reduced and it can be produced by an elastic washer acting between the two elements. According to one embodiment, the sleeve comprises an internal element secured to the neck base and an external threaded element, the two elements being joined by a thin veil which is elastically deformable. In the context of this embodiment, the internal element can be forcibly engaged on a straight neck of the peripheral ring type or be screwed on a threaded neck.

D'autres caractéristiques de la présente invention apparaîtront à la lecture de la description détaillée de divers modes de réalisation faite ci-après avec référence au dessin ci- annexé dans lequel :

  • La figure 1 est une vue en coupe axiale d'un dispositif de bouchage selon un premier mode de réalisation; la figure 2 en est une vue en coupe par II-II de figure 1; la figure 3 est une vue analogue à figure 1 pour un autre mode de réalisation; la figure 4 est une vue analogue à figure 1 pour encore un autre mode de réalisation; La figure 5 est une vue en coupe axiale d'un dispositif de bouchage dans lequel le manchon fileté et l'élément de sollicitation élastique sont réalisés en une seule pièce, et la figure 6 est une vue analogue à figure 5 pour un mode de réalisation dans lequel le dispositif est analogue à celui de figure 5.
Other characteristics of the present invention will appear on reading the detailed description of various embodiments given below with reference to the attached drawing in which:
  • Figure 1 is an axial sectional view of a closure device according to a first embodiment; Figure 2 is a sectional view through II-II of Figure 1; Figure 3 is a view similar to Figure 1 for another embodiment; Figure 4 is a view similar to Figure 1 for yet another embodiment; FIG. 5 is a view in axial section of a closure device in which the threaded sleeve and the elastic biasing element are produced in one piece, and FIG. 6 is a view similar to FIG. 5 for an embodiment in which the device is similar to that of FIG. 5.

Dans les figures, la référence 1 désigne un flacon ou récipient analogue représenté seulement partiellement et la référence 2 désigne dans son ensemble un bouchon du type dit capsule qui comporte un enjoliveur 3 et un capuchon fileté intérieurement 4 qui peuvent être solidarisés de toute manière connue mais sont représentés dans les dessins comme moulés en une seule pièce.In the figures, the reference 1 designates a bottle or similar container shown only partially and the reference 2 designates as a whole a cap of the so-called capsule type which includes an embellishment 3 and an internally threaded cap 4 which can be secured in any known manner but are shown in the drawings as molded in one piece.

Dans les flacons que concerne l'invention'le bouchon 2 doit, en fin de course de vissage du capuchon 4, venir occuper une position ayant une orientation définie par rapport au flacon 1 soit pour qu'il y ait coincidence entre les sections du flacon et du bouchon, soit pour tout autre motif. Ceci peut se traduire comme illustré dans les figures 1 à 5 par un emboîtement, par le bord 5 de l'enjoliveur 3, d'une saillie 6 prévue sur la surface périphérique du flacon autour du goulot. Si le bord 5 a en plan une forme sensiblement rectangulaire, comme représenté à la figure 2, ovale ou plus généralement toute autre forme non circulaire, l'emboîtement ne peut se faire que par un déplacement longitudinal brusque de l'enjoliveur au moment de la mise en coincidence alors que le déplacement longitudinal assuré par le vissage du capuchon sur le goulot est un déplacement progressif.In vials which the invention 'the plug 2 must in the end screwing travel of the cap 4, to occupy a position having a defined orientation relative to the vial 1 is so that there is coincidence between the sections of the vial and the plug, or for any other reason. This can result, as illustrated in FIGS. 1 to 5, by an interlocking, by the edge 5 of the hubcap 3, of a projection 6 provided on the peripheral surface of the bottle around the neck. If the edge 5 has in plan a substantially rectangular shape, as shown in Figure 2, oval or more general ment any other non-circular shape, the nesting can only be done by a sudden longitudinal movement of the hubcap at the time of coincidence while the longitudinal movement provided by the screwing of the cap on the neck is a progressive movement.

Il faut donc qu'à partir du moment où le bord 5 de l'enjoliveur 3 vient en contact, au cours du vissage du capuchon 4, avec la surface supérieure de la saillie 6, jusqu'à ce que la coïncidence permettant l'emboîtement soit établie, c'est-à-dire pendant une rotation d'une fraction de tour du bouchon qui correspond au vissage du capuchon 4 sur l'élément fileté correspondant d'une longueur égale à une fraction du pas du filet, ce déplacement égal à une fraction du pas soit absorbé par un élément élastique qui, lors de la mise en coincidence, poussera l'enjoliveur dans sa position d'emboîtement.It is therefore necessary that from the moment when the edge 5 of the hubcap 3 comes into contact, during the screwing of the cap 4, with the upper surface of the projection 6, until the coincidence allowing the interlocking is established, that is to say during a rotation of a fraction of a turn of the plug which corresponds to the screwing of the cap 4 on the threaded element corresponding to a length equal to a fraction of the thread pitch, this equal displacement at a fraction of the pitch is absorbed by an elastic element which, when placed in coincidence, will push the hubcap into its nesting position.

Ceci est obtenu conformément à l'invention en désolidarisant élastiquement l'élément fileté 7 entourant le goulot, sur lequel se visse le capuchon fileté 4 du corps 1 du flacon.This is obtained in accordance with the invention by elastically separating the threaded element 7 surrounding the neck, onto which the threaded cap 4 of the body 1 of the bottle is screwed.

Dans le mode de réalisation des figures 1 à 4 le goulot du flacon est remplacé par un embout de goulot 8 généralement cylindrique mais comportant au moins à proximité de sa base des nervures radiales 9. L'élément fileté 7 est constitué par un manchon qui présente près de sa base une collerette interne 10 laquelle présente sur son bord interne des encoches susceptibles de coulisser sur les nervures 9. De ce fait l'élément fileté 7 peut coulisser selon la direction axiale mais ne peut tourner par rapport à l'embout de goulot. Le dispositif est complété par un ressort de compression 11 qui est logé entre l'élément fileté et l'embout de goulot, qui prend appui contre la surface supérieure de la collerette interne 10 et dont l'autre extrémité est solidaire de l'embout de 5 goulot 8 soit par une spire engagée élastiquement dans une gorge 12 de l'embout (figure 1), soit par une bague de butée 13 moulée ou sertie dans la forge 12 (Figure 3), soit par une bague 14 en matière élastique qui emboîte l'extrémité de l'embout en s'engageant dans la gorge 12, cette bague présentant une lèvre interne 15 faisant saillie dans la section du trou du goulot, lèvre avec laquelle coopère la jupe centrale 16 du capuchon pour assurer l'étanchéité.In the embodiment of FIGS. 1 to 4, the neck of the bottle is replaced by a mouthpiece of generally cylindrical neck 8 but comprising radial ribs 9 at least near its base. The threaded element 7 consists of a sleeve which has near its base an internal flange 10 which has on its internal edge notches capable of sliding on the ribs 9. As a result, the threaded element 7 can slide in the axial direction but cannot rotate relative to the neck end . The device is completed by a compression spring 11 which is housed between the threaded element and the neck end piece, which bears against the upper surface of the internal flange 10 and the other end of which is integral with the end piece 5 neck 8 either by a turn engaged elastically in a groove 12 of the end piece (FIG. 1), or by a stop ring 13 molded or crimped in the forge 12 (FIG. 3), or by a ring 14 made of elastic material which fits the end of the end piece while engaging in the groove 12, this ring having an internal lip 15 projecting in the section of the hole in the neck, lip with which the central skirt 16 of the cap cooperates to seal.

Dans les figures 1 et 3, l'étanchëitê est assurée par un bourrelet 17 prévu à la périphérie de la jupe centrale 16, bourrelet qui s'engage à frottement doux dans l'orifice de l'embout de goulot.In FIGS. 1 and 3, the sealing is provided by a bead 17 provided at the periphery of the central skirt 16, a bead which engages with gentle friction in the orifice of the neck end.

Pour accroître la précision de l'orientation du bouchon 2 en position de fermeture, cette précision pouvant être insuffisante si l'on se base uniquement sur un emboîtement du bord 5 de l'enjoliveur et d'une saillie 6 sur le flacon en verrerie en raison des tolérances de la verrerie, on peut prévoir une butée radiale 18 telle qu'illustrée dans la figure 2, butée radiale qui se produit entre une partie du profil périphérique de la saillie 6 et le bord d'un élément 19 solidaire du bouchon. On peut également utiliser dans le même but d'autres types de dispositifs de mise en coincidence tel que celui à dents triangulaires qui sera décrit ci-après avec référence à la figure 6.To increase the precision of the orientation of the stopper 2 in the closed position, this precision may be insufficient if we base ourselves solely on an interlocking of the edge 5 of the hubcap and of a projection 6 on the glassware bottle in due to the tolerances of the glassware, a radial stop 18 can be provided as illustrated in FIG. 2, a radial stop which occurs between a part of the peripheral profile of the projection 6 and the edge of an element 19 secured to the stopper. One can also use for the same purpose other types of coincidence devices such as that with triangular teeth which will be described below with reference to FIG. 6.

Dans le mode de réalisation de la figure 5, l'élément fileté 5 est réalisé en une matière souple, par exemple polypropylène ou polyéthylène moulé, et il est moulé en une seule pièce avec un manchon 20 qui peut s'emboîter à force sur le goulot 21, muni d'un jonc périphérique 22, du flacon 1. L'élément fileté 7 et le manchon 20 sont réunis par un voile 23 qui peut se déformer élastiquement pour permettre un déplacement axial relatif entre les deux éléments sensiblement égal à la profondeur de l'emboîtement entre le bord 5 et la partie en saillie 6.In the embodiment of FIG. 5, the threaded element 5 is made of a flexible material, for example polypropylene or molded polyethylene, and it is molded in one piece with a sleeve 20 which can force fit on the neck 21, provided with a peripheral ring 22, of the bottle 1. The threaded element 7 and the sleeve 20 are joined by a web 23 which can deform elastically to allow relative axial displacement between the two elements substantially equal to the depth of the fitting between the edge 5 and the projecting part 6.

La figure 6 illustre un mode de réalisation analogue mais le manchon 20' est taraudé pour se visser sur le goulot fileté 21' du flacon. Le voile 23' est tronconique et il se déforme à l'allongement radial pour assurer le rappel élastique du bouchon. L'orientation du bouchon par rapport au flacon est assurée par l'engagement de dents longitudinales triangulaires 24 portées par une jupe interne 25 du bouchon dans des encoches 26 de même forme réalisées dans la surface d'extrémité du goulot 21'. Dans le dessin il y a trois dents 24 et trois encoches 26 espacées de 120°. Ceci permet d'assurer l'orientation par rapport.au flacon d'un bouchon à trois axes de symétrie par exemple d'un bouchon triangulaire, hexagonal, trilobé ou analogue.FIG. 6 illustrates a similar embodiment but the sleeve 20 ′ is tapped to be screwed onto the threaded neck 21 'from the bottle. The veil 23 'is frustoconical and it deforms at radial elongation to ensure the elastic return of the plug. The orientation of the stopper with respect to the bottle is ensured by the engagement of triangular longitudinal teeth 24 carried by an internal skirt 25 of the stopper in notches 26 of the same shape made in the end surface of the neck 21 '. In the drawing there are three teeth 24 and three notches 26 spaced 120 ° apart. This ensures orientation relative to the bottle of a stopper with three axes of symmetry, for example of a triangular, hexagonal, three-lobed stopper or the like.

Les modes de réalisation ci-dessus décrits à titre d'exemples sont susceptibles de recevoir de nombreuses modifications sans sortir du cadre de l'invention telle que définie ci-dessus et revendiquée ci-après.The embodiments described above by way of examples are capable of receiving numerous modifications without departing from the scope of the invention as defined above and claimed below.
