Definitions

  • the invention relates to a device for closing a container with a threaded neck such than a tube of paint, gouache, toothpaste or ointment.
  • This device is intended in particular to prevent drying of the contents of the container, the air intakes and the blocking of the plug.

  • This device has the major drawback of requiring the presence of a stopper on the container neck. It therefore requires that the neck of the container be transformed to include this stopper. Such a transformation makes more complex the production of the tubes and it involves an adaptation of the machines to manufacture these tubes. All this translates into a high cost price tubes fitted with such a closure device.
  • Such a device has the advantage of being able to be mounted directly on the neck threaded from a container, without this neck needing to be adapted. In addition, there is removable. Thus, once the container is empty, the device can be recovered and installed on another container.
  • the container is closed, that is to say that the cap 1 is fully screwed onto the neck 2.
  • the obstruction element 3 then obstructs the opening of the stopper, prevents the contents of the container from escaping from it and is pressed against the isolation element 4.
  • the cap has been partially unscrewed.
  • a space has been created 5 between the blocking element 3 and the opening of the plug.
  • the obstruction element 3 can then perform a limited translational movement, designated by the arrow F, along the axis of the neck 2, as well as possibly a rotation around this axis.
  • the isolation element 4 does not move. It has an end 6 which is in tight contact with the internal surface 7 of the plug 1 so as to prevent the contents of the container to infiltrate between the end 6 and the internal surface 7 and to reach the thread 8 of the plug or the thread 9 of the neck 2.
  • Figure 3 illustrates what happens when the user wishes to exit part of the contents of the container outside of the latter.
  • the user then exercises usually pressure on the container body, which causes a push of the contained towards the neck 2 through the isolation element 4 and a displacement of the obstruction element 3 towards the opening of the cap 1.
  • the arrows symbolize the movement of the contents of the container around the obstruction element 3 and towards opening the cap 1.
  • the plug 10 has an axis of revolution X-X, and has a central part 13 generally cylindrical comprising a cylindrical central bore 11 provided in part with a internal thread 12, capable of cooperating with the thread of the neck of a container and a part upper 13bis generally perpendicular to the side wall 14 of the part central 13.
  • An opening 17 is provided in the upper part 13bis for allow the contents of the container to be drained.
  • the internal thread 12 generally extends from the end face 14bis of the central part 13 in the direction of the opening 17, but not to the end of the cylindrical bore 11, so that the wall internal of this bore 11 comprises a sliding surface 18, generally smooth, separating the end 19 of the thread 12 from the upper part 13bis of the plug 10.
  • the internal thread 12 projects relative to the sliding surface 18 so that the plug 10 cannot be easily separated from the rest of the device according to the invention.

  • This flare 22 is dimensioned so that its end 23 comes into contact with the surface sliding 18 over the entire circumference of the bore 11 of the plug 10 and exerts pressure on the sliding surface 18 of the plug 10, so as to produce a tight contact making it impossible for the contents of the container to pass between the end 23 and the sliding surface 18.
  • the isolation element 21, in constituting a tight barrier isolates the contents of the container from the internal thread 12 and container neck thread.
  • the entire circumference of bore 11 should not be understood to mean the entire surface of the wall of bore 11 or the entire sliding surface 18, but as signifying any circumference of a disc obtained by intersection of a plane perpendicular to the axis of the bore 11 and having the diameter of the diameter of the bore 11, said plane can be in any axial position between the end 19 of the thread and the upper part of the plug.
  • the diameter of the flare 22 at its end 23 is therefore at less equal to the diameter of the bore 11 of the plug at its internal surface slip 18. When unscrewing the plug 10, the end 23 scrapes the surface sliding 18.
  • the end 23 may include a surface 23bis parallel to said axis of revolution Y-Y which is itself generally parallel to the X-X axis when the device is installed on a container.
  • the contact between the end 23 and the plug 10 is advantageously made on a small surface so that the pressure on the sliding surface 18 is strong enough and satisfactory sealing. This contact can therefore be linear or practically linear and as it does over the entire circumference of bore 11 of the plug 10, it defines a loop.
  • the dimensions of the plug 10 and of the isolation element 21 are such that said contact is made over a distance following the very weak Y-Y axis, generally at least two times less than the distance over which extends the flare 22 from the fixing means. Therefore, when using the device according to the invention, screwing or unscrewing the plug causes displacement of the end 23 inside the bore 11, along the X-X axis, analogous to the displacement of a disc inside a cylinder.
  • the flare 22 extends from the fixing means and preferably in moving away along the Y-Y axis of the latter. It can therefore define a truncated cone hollow of small thickness compared to its axial length.

  • the flaring 22 is therefore connected, by its part opposite to the end 23, to said fixing means.
  • the fixing means are suitable to, and sized to fit into the neck of the container and able to grip the container neck by applying pressure on all or part of the bore surface from this pass.

They are generally parallel to said axis of symmetry, but when this variant of the isolation element is not mounted on the neck of a container, they can, any extending along the axis of symmetry, move away from each other so as to that we obtain a greater pressure on the bore of the neck of the container, once the device is mounted.
  • the ring 26bis has a diameter at least equal to that of the bore of the container neck so as to exert pressure on this neck and to prevent thus the passage of the contents of the container.

  • This variant 30 is provided with locking means intended to make its sound more difficult extraction from the neck of the container.
  • These blocking means can be presented under the form of a hollow truncated cone 31 projecting from the end 32 of the means fixing 33 opposite to the flare 34. The distance between the base 35 of the flare 34 and the end 32, measured parallel to the axis of symmetry, must then be at less equal to the length of the bore of the container neck, so that this neck can be arranged between the flare 34 and the locking means 31.

If the plug is unscrewed 45, they slide on the surface 46 by exerting a pressure on the latter, while like the end 47 of the flare 44, until the plug 45 is sufficiently unscrewed so that they meet a hollow 48 in the thread of the plug. They can then, as illustrated in FIG. 13b, sink into the hollow 48 because they precede the flare 44 (opposite the internal thread) and have a greater mobility or flexibility as the end 47 of this flare 44.
  • the sinking of the attachment means 43 in a recess 48 then brakes the unscrewing movement and prevents the cap from being unintentionally unscrewed further. User feels when it is more difficult to turn the cap. If he wants to continue unscrewing the cap, in particular with a view to removing it, it must then voluntarily apply more by force. Thus an accidental detachment of the plug 45 relative to the container is made almost impossible.
  • This variant 42 of the isolation element is particularly useful when the thread of the plug 45 does not protrude relative to the sliding surface 46.
  • Figures 14 and 15 show an obstruction element 49 of the device according to the invention.
  • This obstruction element 49 generally has a shape elongated along an axis A-A and preferably symmetrical with respect to this axis. he comprises at least one obturator or obturator part 50 and means for retention.

Description

L'invention concerne un dispositif de fermeture d'un récipient à col fileté tel qu'un tube de peinture, de gouache, de dentifrice ou de pommade. Ce dispositif est destiné notamment à éviter le séchage du contenu du récipient, les prises d'air et le blocage du bouchon.The invention relates to a device for closing a container with a threaded neck such than a tube of paint, gouache, toothpaste or ointment. This device is intended in particular to prevent drying of the contents of the container, the air intakes and the blocking of the plug.

ETAT DE LA TECHNIQUESTATE OF THE ART

Le brevet suisse CH-A-323 486 a pour objet un dispositif de fermeture d'un récipient à col tel qu'un tube, comportant une pièce d'emboutissage, un capuchon, monté par vissage sur le col et deux butées d'arrêt coopérantes ménagées, respectivement, sur le col du récipient et sur le capuchon, pour empêcher celui-ci de se désolidariser du récipient.The Swiss patent CH-A-323,486 relates to a device for closing a neck container such as a tube, comprising a stamping part, a cap, mounted by screwing on the neck and two cooperating stop stops provided, respectively, on the container neck and on the cap, to prevent the latter from detach from the container.

Ce dispositif a pour inconvénient majeur de nécessiter la présence d'une butée d'arrêt sur le col du récipient. Il impose donc que le col du récipient soit transformé de façon à comporter cette butée d'arrêt. Une telle transformation rend plus complexe la production des tubes et elle entraíne une adaptation des machines permettant de fabriquer ces tubes. Tout ceci se traduit par un coût de revient élevé des tubes munis d'un tel dispositif de fermeture.This device has the major drawback of requiring the presence of a stopper on the container neck. It therefore requires that the neck of the container be transformed to include this stopper. Such a transformation makes more complex the production of the tubes and it involves an adaptation of the machines to manufacture these tubes. All this translates into a high cost price tubes fitted with such a closure device.

EXPOSE SOMMAIRE DE L"INVENTIONSUMMARY OF THE INVENTION

L'inventeur est parvenu à mettre au point un dispositif remédiant aux inconvénients précités. Ce dispositif comprend au moins :

  • un bouchon ayant une partie centrale comportant un alésage pourvu d'un taraudage apte à coopérer avec le filetage du col du récipient, et une partie supérieure comportant une ouverture, la fin dudit taraudage étant séparée de ladite partie supérieure par une surface de glissement,
  • un élément d'obstruction de ladite ouverture,
    et se distingue en ce qu'il comprend en outre :
  • un élément d'isolement présentant des moyens de fixation aptes à s'insérer dans le col du récipient et un évasement dont l'extrémité est dimensionnée pour venir en contact avec ladite surface de glissement dudit bouchon sur toute la circonférence dudit alésage de façon à réaliser une barrière étanche lors du vissage et du dévissage du bouchon rendant impossible le passage du contenu du récipient.
The inventor has succeeded in developing a device which remedies the aforementioned drawbacks. This device includes at least:
  • a plug having a central part comprising a bore provided with a tapping capable of cooperating with the threading of the neck of the container, and an upper part comprising an opening, the end of said tapping being separated from said upper part by a sliding surface,
  • an obstruction element of said opening,
    and stands out in that it further comprises:
  • an insulation element having fixing means capable of fitting into the neck of the container and a flare whose end is dimensioned to come into contact with said sliding surface of said plug over the entire circumference of said bore so as to produce a tight barrier during screwing and unscrewing of the cap making it impossible to pass the contents of the container.

Un tel dispositif offre l'avantage de pouvoir être monté directement sur le col fileté d'un récipient, sans que ce col ait besoin d'être adapté. De plus, il reste démontable. Ainsi, une fois le récipient vide, le dispositif peut être récupéré et installé sur un autre récipient.Such a device has the advantage of being able to be mounted directly on the neck threaded from a container, without this neck needing to be adapted. In addition, there is removable. Thus, once the container is empty, the device can be recovered and installed on another container.

    • EXPOSE DETAILLE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

    Le principe de fonctionnement du dispositif selon l'invention est illustré de manière générale par les figures 1, 2 et 3.The operating principle of the device according to the invention is illustrated by generally by Figures 1, 2 and 3.

    Sur la figure 1, le récipient est fermé, c'est-à-dire que le bouchon 1 est entièrement vissé sur le col 2. L'élément d'obstruction 3 obstrue alors l'ouverture du bouchon, empêche le contenu du récipient de s'échapper hors de celui-ci et est plaqué contre l'élément d'isolement 4.In Figure 1, the container is closed, that is to say that the cap 1 is fully screwed onto the neck 2. The obstruction element 3 then obstructs the opening of the stopper, prevents the contents of the container from escaping from it and is pressed against the isolation element 4.

    Sur la figure 2, le bouchon a été partiellement dévissé. Il s'est créé un espace 5 entre l'élément d'obstruction 3 et l'ouverture du bouchon. L'élément d'obstruction 3 peut alors effectuer un mouvement de translation limité, désigné par la flèche F, selon l'axe du col 2, ainsi qu'éventuellement une rotation autour de cet axe. En revanche l'élément d'isolement 4 ne se déplace pas. Il présente une extrémité 6 qui est en contact étanche avec la surface interne 7 du bouchon 1 de façon à empêcher le contenu du récipient de s'infiltrer entre l'extrémité 6 et la surface interne 7 et à atteindre le taraudage 8 du bouchon ou le filetage 9 du col 2. In Figure 2, the cap has been partially unscrewed. A space has been created 5 between the blocking element 3 and the opening of the plug. The obstruction element 3 can then perform a limited translational movement, designated by the arrow F, along the axis of the neck 2, as well as possibly a rotation around this axis. In however the isolation element 4 does not move. It has an end 6 which is in tight contact with the internal surface 7 of the plug 1 so as to prevent the contents of the container to infiltrate between the end 6 and the internal surface 7 and to reach the thread 8 of the plug or the thread 9 of the neck 2.

    La figure 3 illustre ce qui se passe lorsque l'utilisateur souhaite faire sortir une partie du contenu du récipient hors de ce dernier. L'utilisateur exerce alors généralement une pression sur le corps du récipient, ce qui provoque une poussée du contenu vers le col 2 à travers l'élément d'isolement 4 et un déplacement de l'élément d'obstruction 3 vers l'ouverture du bouchon 1. Les flèches symbolisent le mouvement du contenu du récipient autour de l'élément d'obstruction 3 et vers l'ouverture du bouchon 1.Figure 3 illustrates what happens when the user wishes to exit part of the contents of the container outside of the latter. The user then exercises usually pressure on the container body, which causes a push of the contained towards the neck 2 through the isolation element 4 and a displacement of the obstruction element 3 towards the opening of the cap 1. The arrows symbolize the movement of the contents of the container around the obstruction element 3 and towards opening the cap 1.

    Les constituants du dispositif selon l'invention et leurs variantes vont maintenant être décrits plus en détail.The components of the device according to the invention and their variants will now be described in more detail.

    En se référant en particulier aux figure 4 et 5, on voit que le bouchon 10 présente un axe de révolution X-X, et comporte une partie centrale 13 généralement cylindrique comprenant un alésage central cylindrique 11 pourvu en partie d'un taraudage 12, apte à coopérer avec le filetage du col d'un récipient et une partie supérieure 13bis globalement perpendiculaire à la paroi latérale 14 de la partie centrale 13. Une ouverture 17 est prévue dans la partie supérieure 13bis pour permettre l'évacuation du contenu du récipient. Le taraudage 12 s'étend en général depuis la face d'extrémité 14bis de la partie centrale 13 en direction de l'ouverture 17, mais pas jusqu'à l'extrémité de l'alésage cylindrique 11, de sorte que la paroi interne de cet alésage 11 comprenne une surface de glissement 18, généralement lisse, séparant la fin 19 du taraudage 12 de la partie supérieure 13bis du bouchon 10. De préférence, la taraudage 12 fait saillie par rapport à la surface de glissement 18 de façon à ce que le bouchon 10 ne puisse pas être facilement désolidarisé du reste du dispositif selon l'invention.With particular reference to FIGS. 4 and 5, it can be seen that the plug 10 has an axis of revolution X-X, and has a central part 13 generally cylindrical comprising a cylindrical central bore 11 provided in part with a internal thread 12, capable of cooperating with the thread of the neck of a container and a part upper 13bis generally perpendicular to the side wall 14 of the part central 13. An opening 17 is provided in the upper part 13bis for allow the contents of the container to be drained. The internal thread 12 generally extends from the end face 14bis of the central part 13 in the direction of the opening 17, but not to the end of the cylindrical bore 11, so that the wall internal of this bore 11 comprises a sliding surface 18, generally smooth, separating the end 19 of the thread 12 from the upper part 13bis of the plug 10. Preferably, the internal thread 12 projects relative to the sliding surface 18 so that the plug 10 cannot be easily separated from the rest of the device according to the invention.

    Il est avantageux de s'arranger pour que la distance axiale sur laquelle s'étend la surface de glissement 18 soit voisine de celle sur laquelle s'étend le taraudage 12 : on a ainsi une grande latitude de règlage de la quantité de matière sortant du récipient.It is advantageous to arrange so that the axial distance over which extends the sliding surface 18 is close to that on which the thread 12 extends: there is thus a great latitude of adjustment of the quantity of matter leaving the container.

    Un second alésage 20, de préférence en forme de tronc de cône ou de sphère, peut être ménagé entre l'ouverture 17 et l'alésage 11, de façon à faciliter la sortie du contenu du récipient.A second bore 20, preferably in the form of a truncated cone or sphere, can be provided between the opening 17 and the bore 11, so as to facilitate the exit of the contents of container.

    En se reportant aux figures 6 et 7, on remarque que l'élément d'isolement 21 présente un axe de révolution Y-Y et comporte un évasement 22 qui s'étend depuis des moyens de fixation, en s'éloignant dudit axe de révolution. Cet évasement 22 est dimensionné de manière à ce que son extrémité 23 vienne en contact avec la surface de glissement 18 sur toute la circonférence de l'alésage 11 du bouchon 10 et exerce une pression sur la surface de glissement 18 du bouchon 10, de façon à réaliser un contact étanche rendant impossible le passage du contenu du récipient entre l'extrémité 23 et la surface de glissement 18. Ainsi, l'élément d'isolement 21, en constituant une barrière étanche, isole le contenu du récipient du taraudage 12 et du filetage du col du récipient.Referring to Figures 6 and 7, it is noted that the isolation element 21 has an axis of revolution Y-Y and has a flare 22 which extends from fixing means, moving away from said axis of revolution. This flare 22 is dimensioned so that its end 23 comes into contact with the surface sliding 18 over the entire circumference of the bore 11 of the plug 10 and exerts pressure on the sliding surface 18 of the plug 10, so as to produce a tight contact making it impossible for the contents of the container to pass between the end 23 and the sliding surface 18. Thus, the isolation element 21, in constituting a tight barrier, isolates the contents of the container from the internal thread 12 and container neck thread.

    L'expression "toute la circonférence de l'alésage 11" telle qu'utilisée dans la présente description ne doit pas être entendue comme désignant toute la surface de la paroi de l'alésage 11 ou toute la surface de glissement 18, mais comme signifiant toute circonférence d'un disque obtenu par intersection d'un plan perpendiculaire à l'axe de l'alésage 11 et ayant pour diamètre le diamètre de l'alésage 11, ledit plan pouvant se trouver à n'importe quelle position axiale située entre la fin 19 du taraudage et la partie supérieure du bouchon.The expression "the entire circumference of bore 11" as used in the this description should not be understood to mean the entire surface of the wall of bore 11 or the entire sliding surface 18, but as signifying any circumference of a disc obtained by intersection of a plane perpendicular to the axis of the bore 11 and having the diameter of the diameter of the bore 11, said plane can be in any axial position between the end 19 of the thread and the upper part of the plug.

    Le diamètre de l'évasement 22 au niveau de son extrémité 23 est donc au moins égal au diamètre de l'alésage 11 du bouchon au niveau de sa surface interne de glissement 18. Lors du dévissage du bouchon 10, l'extrémité 23 râcle la surface de glissement 18.The diameter of the flare 22 at its end 23 is therefore at less equal to the diameter of the bore 11 of the plug at its internal surface slip 18. When unscrewing the plug 10, the end 23 scrapes the surface sliding 18.

    On évite ainsi l'encrassement à la fois du filetage du col du récipient et du taraudage 12 du bouchon 10 et des fuites du contenu du récipient. L'éxtrémité 23 peut comprendre une surface 23bis parallèle audit axe de révolution Y-Y qui est lui-même généralement parallèle à l'axe X-X lorsque le dispositif est installé sur un récipient. Le contact entre l'extrémité 23 et le bouchon 10 se fait avantageusement sur une surface peu importante pour que la pression sur la surface de glissement 18 soit assez forte et l'étanchéité satisfaisante. Ce contact peut donc être linéaire ou pratiquement linéaire et comme il se fait sur toute la circonférence de l'alésage 11 du bouchon 10, il définit une boucle. En général, les dimensions du bouchon 10 et de l'élémént d'isolement 21 sont telles que ledit contact se fait sur une distance suivant l'axe Y-Y très faible, généralement au moins deux fois inférieure à la distance sur laquelle s'étend l'évasement 22 à partir des moyens de fixation. Par conséquent, lors de l'utilisation du dispositif selon l'invention, le vissage ou le dévissage du bouchon provoque un déplacement de l'extrémité 23 l'intérieur de l'alésage 11, le long de l'axe X-X, analogue au déplacement d'un disque à l'intérieur d'un cylindre.This prevents contamination of both the thread of the neck of the container and the tapping 12 of the plug 10 and leakage of the contents of the container. The end 23 may include a surface 23bis parallel to said axis of revolution Y-Y which is itself generally parallel to the X-X axis when the device is installed on a container. The contact between the end 23 and the plug 10 is advantageously made on a small surface so that the pressure on the sliding surface 18 is strong enough and satisfactory sealing. This contact can therefore be linear or practically linear and as it does over the entire circumference of bore 11 of the plug 10, it defines a loop. In general, the dimensions of the plug 10 and of the isolation element 21 are such that said contact is made over a distance following the very weak Y-Y axis, generally at least two times less than the distance over which extends the flare 22 from the fixing means. Therefore, when using the device according to the invention, screwing or unscrewing the plug causes displacement of the end 23 inside the bore 11, along the X-X axis, analogous to the displacement of a disc inside a cylinder.

    L'évasement 22 s'étend à partir des moyens de fixation et de préférence en s'éloignant suivant l'axe Y-Y de ces derniers. Il peut donc définir un tronc de cône creux de faible épaisseur par rapport à sa longueur axiale. Le rapport entre l'épaisseur du tronc de cône et sa distance d'extension à partir des moyens de fixation peut être inférieur à 1/3.The flare 22 extends from the fixing means and preferably in moving away along the Y-Y axis of the latter. It can therefore define a truncated cone hollow of small thickness compared to its axial length. The relationship between the thickness of the truncated cone and its distance of extension from the means of fixation can be less than 1/3.

    L'évasement 22 est donc relié, par sa partie opposée à l'éxtrémité 23, auxdits moyens de fixation. Ces derniers sont destinés à maintenir l'élément d'isolement en place, à lui rendre difficile, voire impossible, toute rotation sur lui-même et toute désolidarisation du col du récipient. Dans ce but, les moyens de fixation sont aptes à, et dimensionnés pour, s'insérer dans le col du récipient et aptes à s'agripper au col du récipient en exerçant une pression sur tout ou partie de la surface de l'alésage de ce col. Ces moyens de fixation peuvent s'étendre sur tout ou partie de la longueur de l'alésage du col du récipient. Ils sont aptes à laisser passer le contenu du récipient vers l'ouverture du bouchon. Ils peuvent être constitués par un cylindre creux 24. L'élément d'isolement a alors sensiblement la forme d'un entonnoir. Le diamètre externe du cylindre 24 est au moins égal à celui de l'alésage du col du récipient et sa longueur peut être inférieure ou supérieure à celle de l'alésage du col du récipient. Le cylindre 24, grâce à la pression qu'il exerce sur le col du récipient, constitue une barrière étanche entre ledit cylindre 24 et ledit col et rend donc impossible, au contenu du récipient, l'accès aux filetage 8 et taraudage 9 (figure 2).The flaring 22 is therefore connected, by its part opposite to the end 23, to said fixing means. These are intended to maintain the isolation element in place, to make it difficult, even impossible, any rotation on itself and any detachment of the container neck. For this purpose, the fixing means are suitable to, and sized to fit into the neck of the container and able to grip the container neck by applying pressure on all or part of the bore surface from this pass. These fixing means can extend over all or part of the length of the container neck bore. They are able to let the contents of the container pass towards the cap opening. They can be constituted by a hollow cylinder 24. The isolation element then has substantially the shape of a funnel. The diameter external of cylinder 24 is at least equal to that of the bore of the container neck and its length may be less than or greater than that of the bore of the container neck. The cylinder 24, thanks to the pressure it exerts on the neck of the container, constitutes a tight barrier between said cylinder 24 and said neck and therefore makes it impossible, contents of the container, access to thread 8 and internal thread 9 (Figure 2).

    Selon une première variante 25 de l'élément d'isolement visible sur les figures 8 et 9, les moyens de fixation sont constitués par au moins une patte 26 et un anneau 26bis. Les pattes 26 qui peuvent, par exemple, être au nombre de quatre, s'étendent depuis la base 27 de l'évasement 28 dans la direction de l'axe de symétrie de cette variante et en s'éloignant de l'extrémité 29 de l'évasement 28. Elles sont généralement parallèles audit axe de symétrie, mais lorsque cette variante de l'élément d'isolement n'est pas montée sur le col d'un récipient, elles peuvent, tout en s'étendant le long de l'axe de symétrie, s'écarter les unes des autres de manière à ce que l'on obtienne une pression plus importante sur l'alésage du col du récipient, une fois le dispositif monté. L'anneau 26bis a un diamètre au moins égal à celui de l'alésage du col du récipient de façon à exercer une pression sur ce col et à empêcher ainsi le passage du contenu du récipient. L'extrémité 29 est dépourvue de surface parallèle à l'axe longitudinal de cette variante 25 et fait donc un angle par rapport à la surface de glissement du bouchon. Il s'ensuit que le contact entre le bouchon et l'extrémité 29 se fait suivant un cercle.According to a first variant 25 of the insulation element visible on the Figures 8 and 9, the fixing means are constituted by at least one tab 26 and a 26bis ring. The legs 26 which may, for example, be four in number, extend from the base 27 of the flare 28 in the direction of the axis of symmetry of this variant and away from the end 29 of the flare 28. They are generally parallel to said axis of symmetry, but when this variant of the isolation element is not mounted on the neck of a container, they can, any extending along the axis of symmetry, move away from each other so as to that we obtain a greater pressure on the bore of the neck of the container, once the device is mounted. The ring 26bis has a diameter at least equal to that of the bore of the container neck so as to exert pressure on this neck and to prevent thus the passage of the contents of the container. The end 29 has no surface parallel to the longitudinal axis of this variant 25 and therefore makes an angle with respect to the sliding surface of the cap. It follows that the contact between the plug and the end 29 is made in a circle.

    La figure 10 illustre une seconde variante 30 de l'élément d'isolement. Cette variante 30 est pourvue de moyens de blocage destinés à rendre plus diffile son extraction du col du récipient. Ces moyens de blocage peuvent se présenter sous la forme d'un tronc de cône creux 31 faisant saillie depuis l'extrémité 32 des moyens de fixation 33 opposée à l'évasement 34. La distance entre la base 35 de l'évasement 34 et l'extrémité 32, mesurée parallèlement à l'axe de symétrie, doit alors être au moins égale à la longueur de l'alésage du col du récipient, de façon à ce que ce col puisse se disposer entre l'évasement 34 et les moyens de blocage 31.FIG. 10 illustrates a second variant 30 of the isolation element. This variant 30 is provided with locking means intended to make its sound more difficult extraction from the neck of the container. These blocking means can be presented under the form of a hollow truncated cone 31 projecting from the end 32 of the means fixing 33 opposite to the flare 34. The distance between the base 35 of the flare 34 and the end 32, measured parallel to the axis of symmetry, must then be at less equal to the length of the bore of the container neck, so that this neck can be arranged between the flare 34 and the locking means 31.

    La figure 11 représente une troisième variante 36 de l'élément d'isolement comportant un évasement 37 en forme de disque s'étendant depuis un cylindre 38. Des moyens d'arrêt 39 faisant saillie par rapport à la paroi extérieure latérale du cylindre 38 sont de préférence prévus à une certaine distance axiale de l'évasement 37 pour limiter la pénétration du cylindre 38 dans l'alésage du col du récipient et pour permettre un dévissage plus important du bouchon. Ces moyens d'arrêt 39 peuvent être constitués par exemple par des bossages, des saillies ou une collerette. Ainsi, quand le dispositif est monté sur un récipient, comme illustré par la figure 12, l'enfoncement du cylindre 38 dans le col du récipient est limité par les moyens d'arrêt 39. Des moyens de blocage 40 ayant la forme d'une bague 40 (figure 11) ou d'un tronc de cône creux 41 (figure 12) peuvent également être prévus à l'extrémité du cylindre 38 opposée à l'évasement 37, de façon à rendre plus diffile son arrachement.Figure 11 shows a third variant 36 of the isolation element comprising a flaring 37 in the form of a disc extending from a cylinder 38. Stop means 39 projecting from the lateral outer wall of the cylinder 38 are preferably provided at a certain axial distance from the flare 37 to limit the penetration of the cylinder 38 into the bore of the container neck and to allow greater unscrewing of the cap. These means of arrest 39 can be constituted for example by bosses, projections or a flange. Thus, when the device is mounted on a container, as illustrated in FIG. 12, the penetration of the cylinder 38 into the neck of the container is limited by the means stop 39. Locking means 40 having the shape of a ring 40 (FIG. 11) or a hollow truncated cone 41 (FIG. 12) can also be provided at the end of the cylinder 38 opposite the flaring 37, so as to make its sound more difficult tearing.

    Les figures 13a et 13b représentent chacune une moitié d'un même dispositif selon l'invention monté sur un col de récipient et comprenant une quatrième variante 42 de l'élément d'isolement.Figures 13a and 13b each represent one half of the same device according to the invention mounted on a container neck and comprising a fourth variant 42 of the isolation element.

    On voit que la variante 42 comporte des moyens de rattachement 43 qui sont reliés de manière souple à l'évasement 44 et de telle façon qu'ils aient normalement tendance à s'éloigner de cet évasement 44. Lorsque le bouchon 45 est entièrement vissé, comme illustré sur la figure 13a, ces moyens de rattachement 43 sont en contact avec la surface de glissement 46 du bouchon 45. Si l'on dévisse le bouchon 45, ils glissent sur la surface 46 en exerçant une pression sur cette dernière, tout comme l'extrémité 47 de l'évasement 44, jusqu'à ce le bouchon 45 soit suffisamment dévissé pour qu'ils recontrent un creux 48 du taraudage du bouchon. Ils peuvent ensuite, comme illustré par la figure 13b, s'enfoncer dans le creux 48 car ils précèdent l'évasement 44 (vis-à-vis du taraudage) et présentent une plus grande mobilité ou souplesse que l'extrémité 47 de cet évasement 44. L'enfoncement des moyens de rattachement 43 dans un creux 48 freine alors le mouvement de dévissage et évite que le bouchon soit involontairement dévissé davantage. L'utilisateur sent alors qu'il est plus difficile de tourner le bouchon. S'il veut continuer à dévisser le bouchon, en vue notamment de l'enlever, il doit alors appliquer volontairement plus de force. Ainsi une désolidarisation accidentelle du bouchon 45 par rapport au récipient est rendue quasiment impossible.We see that the variant 42 includes attachment means 43 which are flexibly connected to the flare 44 and in such a way that they normally tendency to move away from this flare 44. When the plug 45 is fully screwed, as illustrated in FIG. 13a, these attachment means 43 are in contact with the sliding surface 46 of the plug 45. If the plug is unscrewed 45, they slide on the surface 46 by exerting a pressure on the latter, while like the end 47 of the flare 44, until the plug 45 is sufficiently unscrewed so that they meet a hollow 48 in the thread of the plug. They can then, as illustrated in FIG. 13b, sink into the hollow 48 because they precede the flare 44 (opposite the internal thread) and have a greater mobility or flexibility as the end 47 of this flare 44. The sinking of the attachment means 43 in a recess 48 then brakes the unscrewing movement and prevents the cap from being unintentionally unscrewed further. User feels when it is more difficult to turn the cap. If he wants to continue unscrewing the cap, in particular with a view to removing it, it must then voluntarily apply more by force. Thus an accidental detachment of the plug 45 relative to the container is made almost impossible.

    Cette variante 42 de l'élément d'isolement est particulièrement utile lorsque le taraudage du bouchon 45 ne fait pas saillie par rapport à la surface de glissement 46.This variant 42 of the isolation element is particularly useful when the thread of the plug 45 does not protrude relative to the sliding surface 46.

    Les figures 14 et 15 représentent un élément d'obstruction 49 du dispositif selon l'invention. Cet élément d'obstruction 49 présente généralement une forme allongée le long d'un axe A-A et de préférence symétrique par rapport à cet axe. Il comprend au moins une partie obturatrice ou obturateur 50 et des moyens de rétention.Figures 14 and 15 show an obstruction element 49 of the device according to the invention. This obstruction element 49 generally has a shape elongated along an axis A-A and preferably symmetrical with respect to this axis. he comprises at least one obturator or obturator part 50 and means for retention.

    L'obturateur 50 comporte une partie supérieure 51, une partie médiane 52 et une partie inférieure 53. La partie supérieure 51 est destinée à obstruer l'ouverture du bouchon du dispositif pour fermer ainsi de manière étanche le récipient. Elle présente donc généralement une forme complémentaire de celle de l'ouverture 17 et/ou, le cas échéant, de l'alésage 20 du bouchon 10 (figures 4 et 5).The shutter 50 has an upper part 51, a middle part 52 and a lower part 53. The upper part 51 is intended to obstruct the opening of the cap of the device to thereby seal the container. She therefore generally has a shape complementary to that of the opening 17 and / or, where appropriate, the bore 20 of the plug 10 (Figures 4 and 5).

    La partie médiane 52 peut revêtir des formes très diverses mais elle doit bien évidemment, comme les parties inférieure 53 et supérieure 51, être dimensionnée de telle sorte qu'elle puisse s'insérer dans l'alésage central 11 du bouchon 10 (figure 4) et s'y mouvoir.The middle part 52 can take a variety of forms, but it must obviously, like the lower 53 and upper 51 parts, be sized to so that it can be inserted into the central bore 11 of the plug 10 (Figure 4) and move there.

    La partie inférieure 53 est destinée à venir en butée au moins partiellement contre l'évasement de l'élément d'isolement. De préférence, elle présente une forme telle que lorsque le bouchon est entièrement vissé, les points de contact entre la partie inférieure 53 et ledit évasement définissent une boucle. Ceci a pour avantage de former une seconde barrière d'étanchéité entre l'extérieur du récipient et son contenu, la première barrière d'étanchéité étant constituée par l'obstruction de l'ouverture du bouchon par la partie supérieure 51.The lower part 53 is intended to come into abutment at least partially against the flaring of the insulation element. Preferably, it has a shape such that when the cap is fully screwed in, the contact points between the lower part 53 and said flare define a loop. This has the advantage to form a second sealing barrier between the outside of the container and its contained, the first sealing barrier being constituted by the obstruction of the opening of the plug by the upper part 51.

    L'obturateur 50 peut avoir globalement, par exemple, une forme sphérique (figures 14,15), ovoïde, ou la forme d'un cylindre plein chanfreiné sur ses deux extrémités opposées (figures 16,18).The shutter 50 may have overall, for example, a spherical shape (Figures 14,15), ovoid, or the shape of a solid cylinder chamfered on both opposite ends (Figures 16,18).

    Les moyens de rétention s'étendent depuis un endroit situé sur la partie inférieure 53 et prévu pour se trouver en-dessous desdits points de contact entre l'évasement et la partie inférieure 53, et s'éloignent de cette dernière dans une direction parallèle à l'axe A-A ou faisant un angle faible avec cet axe.The retention means extend from a place located on the part lower 53 and intended to be below said contact points between the flare and the lower part 53, and move away from the latter in a direction parallel to the axis A-A or making a slight angle with this axis.

    Une partie au moins des moyens de rétention doit pouvoir s'insérer avec un certain jeu à l'intérieur des moyens de fixation de l'élément d'isolement et s'y déplacer selon une direction sensiblement parallèle à l'axe de symétrie A-A.At least part of the retention means must be able to be inserted with a some play inside the fixing means of the isolation element and there move in a direction substantially parallel to the axis of symmetry A-A.

    Les moyens de rétention peuvent comprendre à une extrémité opposée à la partie inférieure 53, des moyens d'arrêt faisant saillie par rapport au moyens de fixation de l'élément d'isolement et/ou éventuellement par rapport à l'alésage du col du récipient. Le rôle de ces moyens d'arrêt est de retenir l'élément d'obstruction et de limiter sa mobilité par rapport à l'élément d'isolement et l'amplitude de son déplacement vers l'ouverture du bouchon. Les moyens d'arrêt empêchent aussi l'élément d'obstruction de se désolidariser du récipient si le bouchon a été ôté. La longueur des moyens de rétention mesurée selon l'axe A-A est alors supérieure à celle des moyens de fixation de l'élement d'isolement. Elle peut être supérieure (voir figures 1 à 3) ou inférieure (voir figure 23) à celle de l'alésage du col du récipient. Elle est généralement choisie inférieure à la longueur de déplacement du bouchon (voir figure 3) de manière à ce que l'on puisse régler, en dévissant plus ou moins le bouchon, la quantité de matière sortant du récipient. En effet, la pression exercée par l'utilisateur sur le corps du récipient pousse l'élément d'obstruction vers l'ouverture, mais une fois que les moyens d'arrêt viennent en butée contre les moyens de blocage ou de maintien de l'élément d'isolement ou éventuellement contre le col du récipient, l'élément d'obstruction a atteint une position extrême qu'il ne peut dépasser, alors que l'on peut continuer à dévisser le bouchon et faciliter davantage ainsi l'évacuation du contenu du récipient.The retention means may comprise at an end opposite to the lower part 53, stop means projecting relative to the means of fixing of the isolation element and / or possibly relative to the bore of the neck of the container. The role of these stop means is to retain the obstruction element and to limit its mobility in relation to the isolation element and the amplitude of its displacement towards the opening of the stopper. Stop means also prevent the obstruction element to separate from the container if the cap has been removed. The length of the retention means measured along the axis A-A is then greater than that of the means for fixing the isolation element. It can be higher (see Figures 1 to 3) or lower (see Figure 23) than that of the bore of the container neck. It is generally chosen to be less than the displacement length of the stopper (see figure 3) so that one can adjust, by unscrewing more or less the cap, the quantity of material leaving the container. Indeed, the pressure exerted by the user on the container body pushes the obstruction element towards the opening, but once the stop means come into abutment against the means for blocking or holding the isolation element or possibly against the neck of the container, the obstruction element has reached an extreme position which it cannot exceed, while one can continue to unscrew the cap and facilitate thus further evacuation of the contents of the container.

    Les moyens de rétention peuvent être composés de plusieurs, par exemple, quatre, pattes 54 (figures 14,15) pouvant se disposer à l'intérieur des moyens de fixation de l'élément d'isolement et se terminant par des moyens d'arrêt revêtant la forme d'ergots 55.The means of retention can be composed of several, for example, four, legs 54 (Figures 14,15) can be arranged inside the means of fixing of the isolation element and ending with stop means covering the lug shape 55.

    Le nombre de pattes 54 importe peu, mais, si lors du montage du dispositif, le jeu entre ces pattes et les moyens de fixation de l'élément d'isolement est faible, il est nécessaire qu'il demeure au moins un espace 56 (figure 15) entre deux au moins d'entre elles pour que le contenu du récipient puisse passer et se diriger vers l'ouverture du bouchon lorsque cela est souhaité. En effet, comme cela est le plus visible sur la figure 3, si les pattes 54 se reliaient et faisaient une boucle et que ledit jeu était faible, il serait très difficile d'extraire le contenu du récipient.The number of legs 54 does not matter, but, if during assembly of the device, the clearance between these tabs and the means for fixing the insulation element is small, it at least one space 56 (figure 15) must remain between at least two of them so that the contents of the container can pass and go to opening the cap when desired. Indeed, as this is the most visible in Figure 3, if the legs 54 connected and made a loop and that said clearance was low, it would be very difficult to extract the contents of the container.

    Les figures 16 et 17 représentent une variante 57 de l'élément d'obstruction dont les moyens de rétention comprennent une seule tige 58 se terminant par une barre 59 faisant un angle, de préférence de 90°, avec l'axe B-B de symétrie longitudinal de cette variante 57.Figures 16 and 17 show a variant 57 of the blocking element whose retention means comprise a single rod 58 ending in a bar 59 making an angle, preferably 90 °, with the axis B-B of symmetry longitudinal of this variant 57.

    Sur la figure 18 est illustré un dispositif selon l'invention installé sur le col d'un récipient et comprenant la variante 57 des figures 16 et 17, un bouchon 60 présentant une ouverture 61 précédée d'un alésage tronconique 62 dont la paroi interne est parallèle avec un premier chanfrein 63 de l'obturateur 64, un élément d'isolement présentant, comme moyens de fixation, un cylindre creux 65 dont la longueur est inférieure à celle de l'alésage du col du récipient et d'où part un évasement 66 tronconique apte à coopérer avec le deuxième chanfrein 67 de l'obturateur 64.In Figure 18 is illustrated a device according to the invention installed on the neck of a container and comprising variant 57 of FIGS. 16 and 17, a stopper 60 having an opening 61 preceded by a frustoconical bore 62 whose wall internal is parallel with a first chamfer 63 of the shutter 64, an element insulation having, as fixing means, a hollow cylinder 65, the length is less than that of the bore of the container neck and where a 66 tapered flare suitable for cooperating with the second chamfer 67 of shutter 64.

    Les figures 19 et 20 représentent une variante 70 de l'élément d'obstruction dont les moyens de rétention comprennent une tige 71 se terminant par quatre pans 72 sensiblement en forme de triangle rectangle et disposés à 90° l'un de l'autre de façon à former une croix lorsqu'ils sont observés en vue de dessous (figure 20). L'obturateur a globalement la forme d'un cylindre plein. Sa partie inférieure 73 comporte un chanfrein 74, sa partie médiane 75 est purement cylindrique et sa partie supérieure 76 a la forme d'un tronc de sphère.Figures 19 and 20 show a variant 70 of the blocking element whose retention means comprise a rod 71 ending in a four-sided 72 substantially in the shape of a right triangle and arranged at 90 ° from one another so as to form a cross when viewed from below (Figure 20). The shutter is generally in the form of a full cylinder. Its lower part 73 has a chamfer 74, its middle part 75 is purely cylindrical and its part upper 76 has the shape of a sphere trunk.

    La figure 21 représente un dispositif selon l'invention placé sur le col d'un récipient. Ce dispositif est composé de la variante 70 des figures 19 et 20, d'un élément d'isolement analogue à celui de la figure 12, mais avec en outre un chanfrein 77 dont les parois sont parallèles au chanfrein 74 de la variante 70 et d'un bouchon 78 dont l'alésage 79 précédant l'ouverture 80 présente une forme complémentaire de celle de la partie supérieure 76 de la variante 70. Les côtés 81 des pans 72 sont sensiblement parallèles à la surface interne 75 des moyens de blocage 41 de l'élément d'isolement de la figure 12.FIG. 21 represents a device according to the invention placed on the neck of a container. This device is composed of variant 70 of Figures 19 and 20, a insulation element similar to that of FIG. 12, but also with a chamfer 77 whose walls are parallel to chamfer 74 of variant 70 and a plug 78 whose bore 79 preceding opening 80 has a shape complementary to that of the upper part 76 of the variant 70. The sides 81 sections 72 are substantially parallel to the internal surface 75 of the means of blocking 41 of the isolation element of FIG. 12.

    Sur la figure 22 est représentée une variante d'un dispositif selon l'invention comprenant outre le bouchon 82, l'élément d'isolement 83 et l'élément d'obstruction 84, une bague 85 présentant, sur sa périphérie, un filetage 86 apte à coopérer avec le taraudage du bouchon 82 et sur sa paroi interne, un taraudage 87 apte à coopérer avec le filetage du col du récipient. Cette bague 85 présente de préférence une épaisseur, mesurée selon son axe de révolution, au moins égale à la longueur sur laquelle s'étend le filetage du col du récipient.FIG. 22 shows a variant of a device according to the invention comprising, in addition to the plug 82, the isolation element 83 and the obstruction element 84, a ring 85 having, on its periphery, a thread 86 capable of cooperating with the thread of plug 82 and on its internal wall, thread 87 able to cooperate with the thread of the container neck. This ring 85 preferably has a thickness, measured along its axis of revolution, at least equal to the length over which extends the thread of the container neck.

    Cette variante offre l'avantage de permettre l'utilisation d'un bouchon 82 de grand diamètre et pouvant avoir une ouverture de diamètre important. Des quantités importantes de matière peuvent alors être extraires rapidement du récipient.This variant offers the advantage of allowing the use of a plug 82 of large diameter and may have a large diameter opening. Quantities large amounts of material can then be quickly removed from the container.

    Sur la figure 23 est représentée un autre variante d'un dispositif selon l'invention, dans laquelle l'élement d'isolement 88 est relié à une bague 89 analogue à celle de la figure 22 par un épaulement 90 de façon à former une structure d'un seul tenant. La cylindre 91 de l'élément d'isolement 88 peut s'étendre seulement sur une partie de la longueur de l'alésage du col fileté. L'espace situé entre le cylindre 91 et le tauradage 92 de la bague 89 est dimensionné pour pouvoir recevoir le col du récipient. La bague est de préférence vissée jusqu'à ce que le col fileté vienne en butée contre l'épaulement 90. Le col se trouve alors pincé entre la bague 89 et le cylindre 91, en raison de la pression exercée par ce dernier. L'élement d'obstruction 93 peut être retenu par des pattes 94 d'une longueur suffisamment faible pour qu'elles ne débouchent pas hors du col. Les ergots 95 terminant les pattes 94 ne font pas saillie par rapport à la paroi 96 de l'alésage du col mais il font saillie par rapport à la paroi interne 97 du cylindre 91 de façon à retenir l'élément d'obstruction 93 et à limiter ses déplacements vers l'ouverture du bouchon et donc vers l'extérieur du récipient. FIG. 23 shows another variant of a device according to the invention, in which the isolation element 88 is connected to a similar ring 89 to that of FIG. 22 by a shoulder 90 so as to form a structure of a in one piece. The cylinder 91 of the isolation element 88 may extend only over part of the length of the threaded neck bore. The space between the cylinder 91 and the shrinking 92 of the ring 89 is sized to be able to receive the neck of the container. The ring is preferably screwed until the threaded neck comes in abutment against the shoulder 90. The neck is then pinched between the ring 89 and the cylinder 91, due to the pressure exerted by the latter. The obstruction element 93 can be retained by legs 94 of a length short enough to that they do not open out of the cervix. The lugs 95 ending the legs 94 do not not protruding from wall 96 of the neck bore but protruding from to the internal wall 97 of the cylinder 91 so as to retain the obstruction element 93 and to limit its movements towards the opening of the cap and therefore towards the outside of the container.

    Sur la figure 24 est illustrée une autre encore variante du dispositif selon l'invention dans laquelle l'élément d'isolement 98 et l'élément d'obstruction 99 représenté en coupe, forment une structure d'un seul tenant. L'élément d'isolement 98 peut être analogue, par exemple, à celui représenté sur la figure 10. L'élément d'obstruction 99 est généralement dans ce cas dépourvu de moyens de rétention. Il peut alors n'être constitué que d'un obturateur tel que, par exemple l'obturateur 50 visible sur la figure 14. Cependant, comme le rattachement de l'élément d'obstruction 99 peut être réalisé par un anneau de liaison ou de soudure 100 situé à peu près à la base de l'évasement de l'élément d'isolement 98 et sur sa face interne, (c'est-à-dire tournée vers l'axe de symétrie), l'élément d'obstruction 99 doit être pourvu d'au moins un canal 101 le traversant. Ce canal 101 part d'un point situé sous l'anneau 100, c'est-à-dire à l'intérieur du cylindre 102 de l'élément d'isolement 98, et débouche au-dessus de l'anneau 100, dans l'espace situé, à l'intérieur du bouchon, entre l'évasement et la partie supérieure de l'élément d'obstruction destinée à obstruer l'ouverture du bouchon. La trajectoire suivie par le contenu du récipient lors de son utilisation est symbolisée par les flèches. En l'absence d'un tel canal 101, le contenu du récipient ne pourrait pas sortir du récipient en raison de la barrière constituée par l'anneau 100.FIG. 24 illustrates yet another variant of the device according to the invention in which the isolation element 98 and the obstruction element 99 shown in section, form a structure in one piece. The isolation element 98 may be similar, for example, to that shown in Figure 10. The element obstruction 99 is generally in this case devoid of retention means. he may then consist only of a shutter such as, for example the shutter 50 visible in Figure 14. However, as the attachment of the element obstruction 99 can be achieved by a bonding or welding ring 100 located at roughly at the base of the flaring of the isolation element 98 and on its internal face, (i.e. facing the axis of symmetry), the blocking element 99 must be provided with at least one channel 101 passing through it. This channel 101 starts from a point located under the ring 100, that is to say inside the cylinder 102 of the isolation element 98, and opens above the ring 100, into the space located inside the plug, between the flare and the upper part of the blocking element intended to obstruct the opening of the cap. The trajectory followed by the content of the container when in use is symbolized by the arrows. In the absence of such channel 101, the contents of the container could not exit the container due to the barrier constituted by the ring 100.

    L'élément d'isolement du dispositif selon l'invention peut être constitué d'un matériau assez flexible tel qu'un métal ou alliage de métaux.The isolation element of the device according to the invention may consist of a fairly flexible material such as a metal or metal alloy.

    Le bouchon est généralement en matière plastique. Il est habituellement réalisé par moulage, ce qui lui permet d'avoir des formes complexes.The cap is generally made of plastic. It is usually produced by molding, which allows it to have complex shapes.

    L'élément d'obstruction peut être fait de métal ou d'un alliage de métaux. L'obturateur et les moyens de rétentions peuvent réalisés ensemble ou unis par soudage.The obstruction element may be made of metal or a metal alloy. The shutter and the retention means can be made together or united by welding.

    Le dispositif selon l'invention est donc facile à réaliser et d'un faible prix de revient.The device according to the invention is therefore easy to produce and at a low cost of come back.

    Il peut facilement être mis en place sur un col fileté de la manière suivante :

  • a) on glisse ou introduit de force les moyens de fixation de l'élément d'isolement dans l'alésage du col du récipient, jusqu'à ce que l'évasement vienne en butée contre le col; ce dernier est alors, le cas échéant, enserré entre l'évasement et les moyens de blocage;
  • b) on introduit de force les moyens d'arrêt suivis des moyens de rétention de l'élément d'obstruction entre les moyens de fixation de l'élément d'isolement, jusqu'a ce que se produise un encliquetage; grâce au jeu existant entre les moyens de fixation et les moyens de rétention, l'élément d'obstruction peut alors se déplacer librement le long son axe de symétrie sur une distance limitée;
  • c) on met en place le bouchon en le vissant sur l'extrémité de l'évasement ou en introduisant de force cette extrémité dans l'alésage central du bouchon et en l'enfonçant jusqu'à ce que le taraudage du bouchon vienne en prise avec le filetage du col;
  • d) on peut ensuite fermer le récipient en vissant à fond le bouchon, c'est-à-dire normalement jusqu'à ce que la partie supérieure de l'obturateur vienne en butée contre la partie supérieure du bouchon. Toutefois, si les différents éléments du dispositif n'ont pas été dimensionnés correctement, le vissage ne pourra se faire que jusqu'à ce que l'extrémité de l'évasement vienne en butée contre la partie supérieure du bouchon, ou jusqu'à ce que le bas du bouchon vienne en butée contre le corps du récipient.
    • It can easily be installed on a threaded neck as follows:
  • a) the means for fixing the isolation element are slid or inserted by force into the bore of the neck of the container, until the flare comes into abutment against the neck; the latter is then, if necessary, sandwiched between the flare and the locking means;
  • b) the stopping means followed by means for retaining the obstruction element are forcibly inserted between the means for fixing the isolation element, until a snap-action occurs; thanks to the play existing between the fixing means and the retention means, the obstruction element can then move freely along its axis of symmetry over a limited distance;
  • c) the plug is put in place by screwing it onto the end of the flare or by forcibly inserting this end into the central bore of the plug and pushing it in until the thread of the plug comes into engagement with neck thread;
  • d) the container can then be closed by screwing the stopper fully down, that is to say normally until the upper part of the shutter abuts against the upper part of the stopper. However, if the various elements of the device have not been dimensioned correctly, the screwing can only be done until the end of the flare abuts against the upper part of the plug, or until that the bottom of the cap abuts against the body of the container.

    • Bien évidemment, l'invention n'est en aucune façon limitée par les particularités qui ont été précisées dans ce qui précède ou par les détails des modes de réalisation ou des variantes choisis pour l'illustrer. Nombre de modifications peuvent être apportées aux réalisations particulières et aux variantes qui ont été décrits à titre d'illustration et à leurs éléments constitutifs sans sortir pour autant du cadre de l'invention.Obviously, the invention is in no way limited by the peculiarities which have been specified in the foregoing or by the details of the modes of realization or variants chosen to illustrate it. Number of changes can be made to particular achievements and variants that have been described by way of illustration and their constituent elements without departing from the part of the invention.
