Description

L'invention se rapporte à un dispositif de bouchage pour une bonbonne comportant un col muni d'un bourrelet extérieur à sa partie extrême libre et destinée à un distributeur de liquide du type « fontaine à eau ».The invention relates to a closure device for a cylinder comprising a collar provided with a bead outside at its free end and intended for a dispenser of liquid of the “water fountain” type.

La distribution d'eau par des fontaines généralement réfrigérées est un système très courant dans des pays tels que les Etats-Unis d'Amérique et certains pays asiatiques. L'eau à distribuer est livrée dans des bonbonnes d'une contenance de cinq galons (19/20 litres) qui sont placés à l'envers sur le distributeur, ce dernier permettant de distribuer l'eau par volumes plus petits, par exemple dans des verres.The distribution of water by generally refrigerated fountains is a very common in countries such as the United States of America and some Asian countries. The water to be distributed is delivered in cylinders with a capacity of five gallons (19/20 liters) which are placed upside down on the dispenser, the latter allowing distribute the water in smaller volumes, for example in glasses.

L'invention concerne plus particulièrement les dispositifs de bouchage communément appelés « non-spill », c'est-à-dire qui permettent, grâce à un système de clapet intérieur qui libère le passage de l'eau hors de la bonbonne uniquement lorsque cette dernière se trouve en place sur le distributeur, de mettre en place la bonbonne sur le distributeur et de la retirer du distributeur, même avant qu'elle ne soit vide, sans risque d'écoulement du contenu de la bonbonne.The invention relates more particularly to plugging devices commonly called "non-spill", that is to say which allow, thanks to an internal valve system which releases the passage of water out of the cylinder only when the latter is in place on the distributor, to set up the cylinder on the distributor and remove it from the dispenser, even before it is empty, without risk the contents of the cylinder.

De tels dispositifs de bouchage sont connus, notamment par le document FR-A-2 769 004 issu de la demanderesse.Such closure devices are known, in particular from the document FR-A-2 769 004 from the plaintiff.

Un tel dispositif comporte généralement une capsule en matière plastique comprenant une paroi transversale d'extrémité de laquelle font saillie dans le même sens, d'une part une jupe extérieure sensiblement cylindrique, pourvue d'un bourrelet intérieur pour l'accrochage derrière le bourrelet du col de la bonbonne et, d'autre part, une cheminée intérieure sensiblement cylindrique destinée à recevoir une canule de soutirage prévue sur le distributeur pour venir s'emboíter dans la cheminée depuis la paroi transversale d'extrémité de la capsule, lors de la mise en place de la bonbonne sur le distributeur.Such a device generally comprises a plastic capsule comprising a transverse end wall from which project in the same direction, on the one hand a substantially cylindrical outer skirt, provided with an inner bead for the hanging behind the bead of the neck of the cylinder and, on the other hand, a chimney substantially cylindrical interior intended to receive a withdrawal cannula provided on the distributor to come fit into the chimney from the transverse wall end of the capsule, when placing the bottle on the dispenser.

En outre, le dispositif peut comporter un opercule d'inviolabilité moulé d'une seule pièce avec la capsule et situé à la naissance de la cheminée, du côté de la paroi transversale, de façon à obturer la cheminée, le dit opercule étant destiné à être irrémédiablement et visiblement détruit lors de l'emboítement de la canule de soutirage dans la cheminéeIn addition, the device may include a tamper-evident seal molded in one piece. with the capsule and located at the start of the chimney, on the side of the transverse wall, so as to close off the chimney, the said cover being intended to be irremediably and visibly destroyed during the fitting of the withdrawal cannula in the chimney

Afin d'assurer une bonne étanchéité entre le col de la bonbonne et le dispositif de bouchage monté sur le dit col, un joint est généralement placé contre la face intérieure de la paroi transversale de la capsule, entre la jupe extérieure et la cheminée. Le joint est destiné à être comprimé axialement entre le rebord du col de la bonbonne et la paroi transversale de la capsule, lorsque le dispositif de bouchage est monté sur le dit col. Le plus souvent, il s'agit d'un joint mousse, plan et discoïdal, au centre duquel se trouve un trou permettant le passage de la cheminée.In order to ensure a good seal between the neck of the cylinder and the plugging mounted on the said neck, a seal is generally placed against the inner face of the transverse wall of the capsule, between the outer skirt and the chimney. Gasket is intended to be compressed axially between the rim of the neck of the cylinder and the transverse wall of the capsule, when the closure device is mounted on the said collar. Most often, it is a flat, discoid foam joint, in the center of which is finds a hole allowing the passage of the chimney.

Un tel dispositif est par exemple décrit dans le document US 5 662 231.Such a device is for example described in document US Pat. No. 5,662,231.

Certains dispositifs de l'art antérieur prévoient une saillie sur la face interne de la paroi transversale de la capsule, la dite saillie étant destinée à pénétrer dans le joint lorsque le dispositif de bouchage est monté sur le col et que le joint est comprimé. Une telle saillie est notamment destinée à empêcher le déplacement relatif du joint par rapport à la paroi transversale de la capsule. On se reportera en particulier aux documents US 5 687 865, US 4 874 023 et US 5 392 939.Certain devices of the prior art provide a projection on the internal face of the wall transverse of the capsule, the said projection being intended to penetrate into the joint when the closure device is mounted on the neck and the seal is compressed. Such a projection is in particular intended to prevent the relative displacement of the seal relative to the transverse wall of the capsule. We will refer in particular to documents US 5 687,865, US 4,874,023 and US 5,392,939.

Toutefois, de tels dispositifs présentent un certain nombre d'inconvénients :

  • d'une part, la saillie ne permet pas toujours un bon maintien du joint contre la paroi transversale de la capsule, le joint pouvant notamment se détacher de la dite paroi en se déplaçant axialement vers l'intérieur de la capsule ;
  • d'autre part, il existe un important effort de cisaillement au niveau de la zone de contact entre la saillie et le joint, ce qui peut conduire à une fissuration ou une rupture du joint, et par conséquent à une perte de l'étanchéité. Ce problème est d'autant plus fréquent que les bonbonnes sont empilées les unes sur les autres sur des palettes, les palettes étant elles-mêmes empilées, de sorte que les bonbonnes sont soumises à d'importants efforts. Il en résulte une dégradation de l'état du joint au cours du stockage et du transport des bonbonnes.
However, such devices have a number of drawbacks:
  • on the one hand, the projection does not always allow good retention of the seal against the transverse wall of the capsule, the seal being able in particular to detach from said wall by moving axially towards the interior of the capsule;
  • on the other hand, there is a significant shearing force at the level of the contact zone between the projection and the seal, which can lead to cracking or rupture of the seal, and consequently to a loss of tightness. This problem is all the more frequent as the cylinders are stacked on top of each other on pallets, the pallets themselves being stacked, so that the cylinders are subjected to significant efforts. This results in a deterioration of the state of the seal during storage and transport of the cylinders.

L'invention a pour but de résoudre ces problèmes.The invention aims to solve these problems.

A cet effet, et selon un premier aspect, l'invention concerne un dispositif de bouchage pour une bonbonne comportant un col muni d'un bourrelet extérieur à sa partie extrême libre et destinée à un distributeur de liquide du type fontaine à eau, le dit dispositif comportant une capsule en matière plastique comprenant une paroi transversale d'extrémité de laquelle fait saillie une jupe extérieure sensiblement cylindrique, pourvue d'un bourrelet intérieur pour l'accrochage derrière le bourrelet du col de la bonbonne, dans lequel la paroi transversale présente, sur sa face intérieure, une gorge annulaire d'axe sensiblement confondu avec l'axe de la dite capsule, délimitée par deux nervures faisant saillie sensiblement perpendiculairement à la dite paroi transversale, la dite gorge étant située, lorsque le dispositif est monté sur le col de la bonbonne, en regard du rebord du dit col, et étant destinée à recevoir un joint coulé ou moulé et à empêcher le déplacement de celui-ci parallèlement à la paroi transversale.To this end, and according to a first aspect, the invention relates to a closure device. for a cylinder comprising a neck provided with a bead outside at its end free and intended for a liquid dispenser of the water fountain type, the said device comprising a plastic capsule comprising a transverse wall end of which projects a substantially cylindrical outer skirt, provided an inner bead for hanging behind the bead of the neck of the cylinder, in which the transverse wall has, on its inner face, an annular groove axis substantially coincident with the axis of said capsule, delimited by two ribs projecting substantially perpendicular to said transverse wall, said groove being located, when the device is mounted on the neck of the cylinder, opposite of the edge of said neck, and being intended to receive a cast or molded joint and to prevent moving it parallel to the transverse wall.

Selon une version plus élaborée, le dispositif de bouchage comprend en outre une cheminée intérieure sensiblement cylindrique, faisant saillie de la paroi transversale d'extrémité dans le même sens que la jupe extérieure de telle sorte que la gorge soit située entre la jupe et la cheminée, la dite cheminée étant destinée à recevoir une canule de soutirage prévue sur le distributeur pour venir s'emboíter dans la cheminée depuis la paroi transversale d'extrémité de la capsule, lors de la mise en place de la bonbonne sur le distributeur, ainsi qu'un opercule d'inviolabilité moulé d'une seule pièce avec la capsule et situé à la naissance de la cheminée, du côté de la paroi transversale de façon à obturer la cheminée, le dit opercule étant destiné à être irrémédiablement et visiblement détruit lors de l'emboítement de la canule de soutirage dans la cheminée.According to a more elaborate version, the closure device further comprises a substantially cylindrical interior chimney projecting from the transverse wall end in the same direction as the outer skirt so that the groove is located between the skirt and the chimney, said chimney being intended to receive a withdrawal cannula provided on the dispenser to fit into the chimney from the transverse end wall of the capsule, when the cylinder on the dispenser, as well as a one-piece molded tamper-evident seal with the capsule and located at the start of the chimney, on the side of the transverse wall so as to close off the chimney, the said cover being intended to be irremediably and visibly destroyed during the nesting of the withdrawal cannula in the chimney.

Selon d'autres caractéristiques, la hauteur axiale des nervures est inférieure à l'épaisseur du joint lorsqu'il n'est pas comprimé. Les extrémités des deux nervures sont décalées axialement l'une par rapport à l'autre. Une première nervure est située axialement, par rapport à l'axe de la capsule, sensiblement aux deux tiers du diamètre de la dite capsule, une deuxième nervure étant située sensiblement à la même distance de l'axe de la capsule que l'extrémité intérieure du bourrelet intérieur de la jupe. According to other characteristics, the axial height of the ribs is less than the thickness of the joint when it is not compressed. The ends of the two ribs are axially offset from each other. A first rib is located axially, with respect to the axis of the capsule, approximately two thirds of the diameter of said capsule, a second rib being located substantially at the same distance of the axis of the capsule as the inner end of the inner bead of the skirt.

De plus, la gorge comprend, sur sa face intérieure, au moins un moyen d'accrochage du joint, empêchant ainsi le déplacement du dit joint hors de la gorge.In addition, the groove comprises, on its inner face, at least one attachment means of the seal, thereby preventing movement of said seal out of the groove.

De la sorte, le joint, mis en place par coulage ou moulage, est maintenu contre la paroi transversale à la fois par une force d'adhésion physico-chimique, et par le ou les moyens mécaniques d'accrochage. De plus, la gorge assure un maintien du joint dans toutes les directions parallèles à la paroi transversale de la capsule.In this way, the seal, put in place by casting or molding, is held against the wall transverse both by a physicochemical adhesion force, and by the mechanical attachment means. In addition, the groove maintains the seal in all directions parallel to the transverse wall of the capsule.

Le procédé de réalisation du joint (par coulage ou par moulage) permet que les moyens mécaniques d'accrochage pénètrent dans la matière constitutive du dit joint avant sa solidification. Ainsi, tout risque de rupture du joint consécutive à l'effort exercé par les moyens d'accrochage est écarté.The method of producing the joint (by casting or by molding) allows the means mechanical attachment penetrate into the material of said seal before its solidification. Thus, any risk of rupture of the joint following the force exerted by the attachment means is discarded.

Selon une première version de l'invention, la gorge comprend, sur sa face intérieure, au moins une saillie formant moyen d'accrochage pour le dit joint.According to a first version of the invention, the groove comprises, on its inner face, at minus a projection forming hooking means for said joint.

Selon un premier mode de réalisation, au moins une nervure comprend une saillie s'étendant sensiblement radialement vers l'intérieur de la gorge.According to a first embodiment, at least one rib comprises a projection extending substantially radially inward of the groove.

La hauteur axiale de la saillie va en diminuant depuis la nervure jusqu'à l'extrémité de la dite saillie, de sorte à former une pointe apte à pénétrer dans le joint. La saillie est située vers la partie extrême libre de la nervure.The axial height of the projection decreases from the rib to the end of the said projection, so as to form a point capable of penetrating into the joint. The projection is located towards the free end of the rib.

Par exemple, chacune des deux nervures comprend une saillie s'étendant sensiblement radialement vers l'intérieur de la gorge.For example, each of the two ribs includes a projection extending substantially radially inward of the throat.

Selon un deuxième mode de réalisation, le fond de la gorge comprend au moins une saillie s'étendant sensiblement axialement vers l'intérieur de la capsule.According to a second embodiment, the bottom of the groove comprises at least one projection extending substantially axially towards the inside of the capsule.

La saillie comprend au moins une face inclinée d'un angle aigu par rapport à l'axe de la capsule de sorte que, lorsque le joint est placé dans la gorge, au moins une zone du dit joint est comprise dans une zone d'accrochage située, axialement, entre le fond de la gorge et une partie de la dite saillie. The projection comprises at least one face inclined at an acute angle relative to the axis of the capsule so that when the seal is placed in the groove, at least one area of the said gasket is included in an attachment zone located axially between the bottom of the throat and part of the said projection.

La saillie présente, en coupe axiale, la forme d'au moins un trapèze dont la grande base est située vers l'extrémité libre de la dite saillie. Le dit trapèze possède un axe de symétrie sensiblement parallèle à l'axe de la capsule.The projection has, in axial section, the shape of at least one trapezium, the large base is located towards the free end of said projection. Said trapezoid has an axis of symmetry substantially parallel to the axis of the capsule.

La hauteur axiale de la saillie est inférieure à la hauteur axiale des nervures.The axial height of the projection is less than the axial height of the ribs.

Selon une réalisation possible, la saillie est annulaire, l'axe de la dite saillie étant sensiblement confondu avec l'axe de la capsule.According to a possible embodiment, the projection is annular, the axis of said projection being substantially coincident with the axis of the capsule.

Selon une deuxième version de l'invention, la face intérieure de la gorge comprend des reliefs localisés tels que des stries, des aspérités, ou équivalent, formant moyen d'accrochage pour le joint.According to a second version of the invention, the inner face of the groove comprises localized reliefs such as ridges, roughness, or the like, forming means attachment for the joint.

Selon un deuxième aspect, l'invention concerne un ensemble comprenant un dispositif de bouchage tel que précédemment décrit et un joint placé dans la gorge de la paroi transversale de la dite capsule, le joint ayant été mis en place par coulage ou par moulage.According to a second aspect, the invention relates to an assembly comprising a device plugging as previously described and a seal placed in the groove of the wall transverse of said capsule, the seal having been put in place by pouring or by molding.

Selon un troisième aspect, l'invention concerne un ensemble comprenant un dispositif de bouchage tel que précédemment décrit, un joint placé dans la gorge de la paroi transversale de la dite capsule, le joint ayant été mis en place par coulage ou par moulage, et une bonbonne, la dite bonbonne étant vide ou au moins partiellement remplie d'un certain contenu.According to a third aspect, the invention relates to an assembly comprising a device as previously described, a seal placed in the groove of the wall transverse of said capsule, the seal having been put in place by pouring or by molding, and a cylinder, said cylinder being empty or at least partially filled with some content.

Lorsque la capsule est montée sur le col de la bonbonne, la gorge est située en regard du rebord du dit col, le joint étant comprimé, dans la gorge, entre la paroi transversale de la capsule et le rebord du col de la bonbonne.When the capsule is mounted on the neck of the cylinder, the throat is located opposite of the rim of said neck, the seal being compressed, in the groove, between the transverse wall of the capsule and the rim of the neck of the cylinder.

Enfin, selon un quatrième aspect, l'invention concerne un procédé de réalisation d'un ensemble capsule - joint. Selon une première variante, on coule le joint dans la gorge de la capsule, la dite capsule ayant été préalablement moulée par injection. Selon une deuxième variante, la capsule et le joint sont réalisés par moulage par bi-injection. Finally, according to a fourth aspect, the invention relates to a method for producing a capsule - seal assembly. According to a first variant, the seal is poured into the groove of the capsule, said capsule having been previously molded by injection. According to one second variant, the capsule and the seal are produced by bi-injection molding.

Le dispositif de bouchage tel qu'illustré par les figures annexées, est destiné au bouchage du col 1 de bonbonnes pour un distributeur d'eau du type fontaine, bonbonnes qui présentent généralement une contenance de cinq galons (19/20 litres) et qui sont constitués par exemple de polycarbonate.
Tel que cela apparaít sur les figures 6 et 7, le col 1 présente, à son extrémité libre, un bourrelet extérieur 2 d'accrochage.The closure device as illustrated by the appended figures, is intended for the closure of the neck 1 of cylinders for a water dispenser of the fountain type, cylinders which generally have a capacity of five gallons (19/20 liters) and which are made for example of polycarbonate.
As shown in Figures 6 and 7, the neck 1 has, at its free end, an outer bead 2 for attachment.

Le dispositif de bouchage comprend une capsule 3 d'axe 4, comprenant une paroi transversale d'extrémité 5 de laquelle font saillie dans le même sens d'une part une jupe extérieure 6 essentiellement cylindrique et d'autre part une cheminée intérieure 7 également de forme essentiellement cylindrique, la hauteur axiale de la cheminée 7 étant ici inférieure à la hauteur axiale de la jupe 6. The closure device comprises a capsule 3 of axis 4, comprising a wall transverse end 5 from which protrude in the same direction on the one hand a outer skirt 6 essentially cylindrical and on the other hand an inner chimney 7 also essentially cylindrical in shape, the axial height of the chimney 7 here being less than the axial height of the skirt 6.

La jupe 6 comporte un bourrelet intérieur 8, par exemple interrompu en plusieurs secteurs, destiné à coopérer avec le bourrelet extérieur 2 du col 1 en vue du maintien de la capsule 3 sur le col 1, par clipage mutuel.The skirt 6 has an inner bead 8, for example interrupted in several sectors, intended to cooperate with the outer bead 2 of the neck 1 in order to maintain of the capsule 3 on the neck 1, by mutual clipping.

La cheminée 7 comprend, sur sa face intérieure, deux reliefs annulaires 9, 10 dont la fonction sera détaillée plus loin.The chimney 7 comprises, on its inner face, two annular reliefs 9, 10, the function will be detailed later.

Un bouchon 11 en forme de godet est emboíté dans la partie extrême libre 12, c'est-à-dire opposée à la paroi transversale 5, de la cheminée 7. Le bouchon 11 comprend essentiellement un fond 13, situé vers l'extrémité libre 16 de la cheminée 7, une paroi 14 sensiblement cylindrique, en saillie par rapport au fond 13, et un rebord annulaire extérieur 15 prévu vers le fond 12 pour venir porter contre l'extrémité libre 16 de la cheminée 7 lors de l'emboítement du bouchon 11 dans la cheminée 7 (voir figures 3 et 6).A plug 11 in the form of a cup is fitted into the free end 12, that is to say opposite the transverse wall 5, of the chimney 7. The plug 11 comprises essentially a bottom 13, located towards the free end 16 of the chimney 7, a wall 14 substantially cylindrical, projecting from the bottom 13, and an annular rim outer 15 provided towards the bottom 12 to come to bear against the free end 16 of the chimney 7 when the plug 11 fits into the chimney 7 (see FIGS. 3 and 6).

Le bouchon 11 comporte en outre :

  • sur la face extérieure de sa paroi cylindrique 14, une première saillie annulaire 17, destinée à coopérer avec le premier relief annulaire 9 de la cheminée 7 lorsque la bonbonne n'est pas mise en place sur le distributeur ;
  • sur la face extérieure de sa paroi cylindrique 14, une saillie deuxième annulaire 18 ou un épaulement 18' destiné à coopérer avec le deuxième relief annulaire 10 de la cheminée 7 lorsque la bonbonne n'est pas mise en place sur le distributeur ;
  • vers l'extrémité libre de sa paroi cylindrique 14, un rebord intérieur 19, dont la fonction apparaítra à la description de la figure 7.
The plug 11 also comprises:
  • on the outer face of its cylindrical wall 14, a first annular projection 17, intended to cooperate with the first annular relief 9 of the chimney 7 when the cylinder is not placed on the distributor;
  • on the outer face of its cylindrical wall 14, a second annular projection 18 or a shoulder 18 'intended to cooperate with the second annular relief 10 of the chimney 7 when the cylinder is not placed on the dispenser;
  • towards the free end of its cylindrical wall 14, an inner rim 19, the function of which will appear in the description of FIG. 7.

A la naissance de la cheminée 7, du côté de la paroi transversale 5, la cheminée 7 est obturée par un opercule 20 qui est moulé d'une seule pièce avec la capsule 3, sous la forme d'un diaphragme de rupture constitué par huit pétales 21 en forme de secteurs de cercle, reliés entre eux par des lignes de déchirure 22 en forme de rayons. De préférence, l'opercule 20 présente une forme légèrement conique, la pointe du cône étant tournée vers le bouchon 11.At the birth of the chimney 7, on the side of the transverse wall 5, the chimney 7 is closed by a cover 20 which is molded in one piece with the capsule 3, under the shape of a rupture diaphragm constituted by eight petals 21 in the form of sectors of circle, interconnected by tear lines 22 in the form of rays. Of preferably, the cover 20 has a slightly conical shape, the tip of the cone being turned towards the plug 11.

Le diamètre et la hauteur axiale de la cheminée 7 sont choisis de manière que lorsque le bouchon 11 est emboíté à fond dans la cheminée 7, son rebord extérieur 15 étant en contact avec l'extrémité libre 16 de la cheminée 7, le rebord intérieur 19 à l'extrémité libre de la paroi cylindrique 14 du bouchon 11 soit éloigné de l'opercule 20 d'une distance correspondant au moins au rayon de la cheminée 7, donc sensiblement à la longueur des pétales 21.The diameter and the axial height of the chimney 7 are chosen so that when the plug 11 is fully fitted into the chimney 7, its outer edge 15 being in contact with the free end 16 of the chimney 7, the inner rim 19 at the end free from the cylindrical wall 14 of the plug 11 is distant from the cover 20 of a distance corresponding at least to the radius of the chimney 7, therefore substantially to the length of petals 21.

La jupe 6 présente intérieurement une ligne de déchirure 23 (ligne d'affaiblissement) qui s'étend depuis l'extrémité libre de la jupe 6, à travers le bourrelet intérieur 8 interrompu à cet endroit, jusqu'entre le bourrelet 8 de la jupe 6 et la paroi transversale 5, sensiblement jusqu'au droit du sommet du bourrelet extérieur 2 du col 1 de la bonbonne. Une patte de préhension 24 prévue sur la jupe 6 permet d'arracher cette dernière, c'est-à-dire de déchirer la capsule 3 suivant la ligne de déchirure 23, ce qui fait que la capsule restante ne tient plus sur le col 1 de la bonbonne.The skirt 6 has internally a tear line 23 (weakening line) which extends from the free end of the skirt 6, through the interrupted inner bead 8 at this point, up between the bead 8 of the skirt 6 and the transverse wall 5, substantially to the right of the top of the outer bead 2 of the neck 1 of the carboy. A gripping tab 24 provided on the skirt 6 makes it possible to tear off this last, that is to say to tear the capsule 3 along the tear line 23, which the remaining capsule no longer fits on the neck 1 of the cylinder.

On décrit à présent la mise en place de la bonbonne munie de la capsule 3 sur un distributeur, en référence à la figure 7, ainsi que le retrait de la bonbonne du distributeur et le remplissage de la dite bonbonne.We now describe the installation of the cylinder with the capsule 3 on a dispenser, with reference to FIG. 7, as well as the removal of the bottle from the dispenser and the filling of the said bottle.

La figure 7 représente la bonbonne remplie d'eau, obturée par la capsule 3, après sa mise en place en position renversée sur un distributeur dont on n'a représenté que la canule de soutirage 25 puisque c'est la seule partie du distributeur qui coopère avec le dispositif de bouchage objet de la présente invention.FIG. 7 represents the bottle filled with water, closed by the capsule 3, after its set up in the inverted position on a distributor of which only the withdrawal cannula 25 since it is the only part of the dispenser which cooperates with the closure device object of the present invention.

La canule de soutirage 25 présente un corps sensiblement cylindrique comportant au moins un trou de soutirage 26 destiné au passage du liquide de l'intérieur de la bonbonne vers l'extérieur du distributeur.The withdrawal cannula 25 has a substantially cylindrical body comprising at minus a withdrawal hole 26 intended for the passage of the liquid from the interior of the cylinder to the outside of the dispenser.

Lors de la mise en place de la bonbonne sur le distributeur, en position renversée, la tête 27 (extrémité supérieure) de la canule de soutirage 25 provoque d'abord la rupture de l'opercule 20 au niveau des lignes de déchirure 22, c'est-à-dire une subdivision de l'opercule 20 en huit pétales 21 qui, restant attachés par leur base à la cheminée 7, sont rabattus vers le haut par la tête 27 de la canule 25. La tête 27 de la canule 25 pénètre ensuite dans le bouchon 11 dont le rebord intérieur 19 vient s'encliqueter dans une gorge 28 ménagée entre la tête 27 et le corps de la canule 25. Ensuite, la canule 25 entraínant le bouchon 11 pousse ce dernier vers le haut hors de la cheminée 7, libérant la première saillie annulaire 17 du premier relief annulaire 9 et la deuxième saillie annulaire 18 - ou l'épaulement 18' - du deuxième relief annulaire 10. L'eau contenue dans la bonbonne peut ainsi s'écouler par les trous de soutirage 26 dans la canule 25, et alimenter le distributeur.When placing the cylinder on the distributor, in the inverted position, the head 27 (upper end) of the withdrawal cannula 25 first causes rupture of the seal 20 at the tear lines 22, that is to say a subdivision of the cover 20 in eight petals 21 which, remaining attached by their base to the chimney 7, are folded up by the head 27 of the cannula 25. The head 27 of the cannula 25 then enters the plug 11, the inner flange 19 of which snaps into a groove 28 formed between the head 27 and the body of the cannula 25. Next, the cannula 25 driving the plug 11 pushes the latter upwards out of the chimney 7, releasing the first annular projection 17 from the first annular relief 9 and the second annular projection 18 - or the shoulder 18 '- of the second annular relief 10. The water contained in the cylinder can thus flow through the withdrawal holes 26 in the cannula 25, and feed the distributor.

Lorsque la bonbonne est soulevée pour être retirée du distributeur, qu'elle soit vide ou qu'elle contienne encore de l'eau, la canule de soutirage 25 sur laquelle le bouchon 11 reste encliqueté emboíte de nouveau le bouchon 11 dans l'extrémité libre de la cheminée 7, jusqu'à ce que le rebord extérieur 15 vienne buter contre l'extrémité libre 16 de la cheminée 7, les saillies 17, 18 coopérant par ailleurs avec les reliefs 9, 10. Ainsi, le bouchon 11 emboíté à fond dans la cheminée 7 se détache de la canule 25, assurant de nouveau l'obturation étanche de la bonbonne.When the cylinder is lifted to be removed from the dispenser, whether it is empty or that it still contains water, the withdrawal cannula 25 on which the plug 11 remains snapped again fits the plug 11 into the free end of the chimney 7, until the outer edge 15 abuts against the free end 16 of the chimney 7, the projections 17, 18 also cooperating with the reliefs 9, 10. Thus, the plug 11 fitted fully into the chimney 7 is detached from the cannula 25, again ensuring the tight sealing of the cylinder.

Pour remplir de nouveau la bonbonne à la source d'origine, on arrache la jupe 6 le long de la ligne de déchirure 23 de la capsule 3 par une traction exercée sur la patte 24, la capsule 3 pouvant alors être retirée à la main sans effort, n'étant plus maintenue sur le col 1 de la bonbonne. Après re-remplissage de la bonbonne, on pose sur le col 1 un nouveau dispositif de bouchage dont l'opercule 20 et la jupe 6 sont intacts, ce qui est une garantie de l'origine du contenu de la bonbonne (double fonction d'inviolabilité).To refill the cylinder at the original source, tear off skirt 6 along of the tear line 23 of the capsule 3 by a traction exerted on the tab 24, the capsule 3 can then be removed by hand without effort, no longer held on the col 1 of the cylinder. After refilling the bottle, we put on the neck 1 a new closure device with the cover 20 and the skirt 6 intact, which is a guarantee of the origin of the contents of the cylinder (double inviolability function).

Selon une réalisation non représentée, le dispositif de bouchage conforme à l'invention peut être muni d'un troisième moyen d'inviolabilité constitué par une bague ou bande circonférentielle d'inviolabilité reliée à l'extrémité libre de la jupe par des moyens frangibles, par exemple une ligne d'affaiblissement ou des ponts discrets, la bague étant engagée derrière un second bourrelet extérieur prévu sur le col 1 de la bonbonne, à distance en dessous du bourrelet supérieur 2. La bague d'inviolabilité ou de garantie peut être de type quelconque, ou constituée par une bague thermorétractable dont la rétraction est produite lors de la pose de la capsule 3, à la suite du remplissage. Cette bague de garantie complète les deux moyens d'inviolabilité ou de garantie constitués par l'opercule 20 et la jupe 6 arrachable.According to an embodiment not shown, the closure device according to the invention may be provided with a third means of inviolability constituted by a ring or band circumferential tamper evident connected to the free end of the skirt by means frangible, for example a weakening line or discrete bridges, the ring being engaged behind a second outer bead provided on the neck 1 of the cylinder, at a distance below the upper bead 2. The tamper-evident or guarantee ring can be of any type, or constituted by a heat-shrinkable ring whose shrinkage is produced during the installation of the capsule 3, following filling. This guarantee ring completes the two means of inviolability or guarantee constituted by the cover 20 and the removable skirt 6.

II convient de remarquer que le dispositif de bouchage selon l'invention peut être utilisé sans bouchon 11. En effet, l'opercule 20, tant qu'il n'est pas détruit par la canule de soutirage 25, non seulement constitue un moyen de garantie ou d'inviolabilité, mais assure également une obturation étanche de la capsule 3. Bien entendu, en l'absence de bouchon 11, la capsule 3 n'empêche pas l'écoulement de l'eau hors de la bonbonne qui serait retirée du distributeur avant d'être complètement vide.It should be noted that the closure device according to the invention can be used without cap 11. In fact, the cap 20, as long as it is not destroyed by the cannula of racking 25, not only constitutes a means of guarantee or inviolability, but also ensures a tight sealing of the capsule 3. Of course, in the absence cap 11, capsule 3 does not prevent the flow of water out of the cylinder which would be removed from the dispenser before being completely empty.

On décrit maintenant, en référence aux figures 3 à 5, les moyens d'étanchéité prévus dans la capsule 3.We will now describe, with reference to Figures 3 to 5, the sealing means provided in capsule 3.

La face intérieure 29 de la paroi transversale 5 présente une gorge 30 annulaire, d'axe sensiblement confondu avec l'axe 4 de la capsule 3.The inner face 29 of the transverse wall 5 has an annular groove 30, of axis substantially coincident with the axis 4 of the capsule 3.

La gorge 30 est délimitée par une première nervure 31, située axialement, par rapport à l'axe 4 de la capsule 3, sensiblement aux deux tiers du diamètre de la dite capsule 3, soit sensiblement à mi-distance entre la cheminée 7 et la jupe extérieure 6, et par une deuxième nervure 32, située vers la périphérie de la paroi transversale 5, sensiblement à la même distance de l'axe 4 de la capsule 3 que l'extrémité intérieure du bourrelet intérieur 8 de la jupe 6, les dites nervures 31, 32 faisant saillie sensiblement perpendiculairement à la paroi transversale 5.The groove 30 is delimited by a first rib 31, located axially, relative to the axis 4 of the capsule 3, substantially two-thirds of the diameter of said capsule 3, either substantially midway between the chimney 7 and the outer skirt 6, and by a second rib 32, located towards the periphery of the transverse wall 5, substantially at the same distance from the axis 4 of the capsule 3 as the inner end of the bead inside 8 of skirt 6, said ribs 31, 32 projecting substantially perpendicular to the transverse wall 5.

Ainsi, la gorge 28 est située, lorsque la capsule 3 est montée sur le col 1 de la bonbonne, en regard du rebord 33 du col 1.Thus, the groove 28 is located, when the capsule 3 is mounted on the neck 1 of the cylinder, opposite the rim 33 of the neck 1.

La gorge 30 est destinée à recevoir un joint 34 torique, mis en place par coulage ou par moulage, comme représenté sur la figure 3. Lorsque la capsule 3 est montée sur le col 1 de la bonbonne, le joint est comprimé, dans la gorge 30, entre le rebord 33 du col 1 et la paroi transversale 5 de la capsule 3.The groove 30 is intended to receive an O-ring 34, put in place by pouring or by molding, as shown in Figure 3. When the capsule 3 is mounted on the neck 1 of the cylinder, the seal is compressed, in the groove 30, between the rim 33 of the neck 1 and the transverse wall 5 of the capsule 3.

La hauteur axiale des nervures 31, 32 est inférieure à l'épaisseur du joint 34 lorsqu'il n'est pas comprimé, mais est suffisante pour assurer le maintien du joint 34 à l'intérieur de la gorge 30. On comprend que la hauteur axiale des nervures 31, 32 est ajustée pour permettre au joint 34 d'assurer une très bonne étanchéité entre la capsule 3 et le col 1, lorsque la capsule 3 est montée sur le col 1 de la bonbonne.The axial height of the ribs 31, 32 is less than the thickness of the joint 34 when it is not compressed, but is sufficient to maintain the seal 34 inside of the groove 30. It is understood that the axial height of the ribs 31, 32 is adjusted to allow the seal 34 to ensure a very good seal between the capsule 3 and the neck 1, when the capsule 3 is mounted on the neck 1 of the cylinder.

Selon une réalisation possible, les extrémités des deux nervures 31, 32 sont décalées axialement l'une par rapport à l'autre. In one possible embodiment, the ends of the two ribs 31, 32 are offset axially with respect to each other.

La gorge 30 permet d'empêcher les déplacements du joint 34 parallèlement à la paroi transversale 5, le joint 34 étant maintenu entre les nervures 31, 32.The groove 30 prevents movement of the seal 34 parallel to the wall transverse 5, the seal 34 being held between the ribs 31, 32.

Afin d'améliorer le maintien du joint 34 dans la gorge 30, et notamment d'empêcher que celui-ci ne s'échappe de la dite gorge 30 par un mouvement axial s'éloignant de la paroi transversale 5, la gorge 30 est pourvue de saillies destinées à pénétrer dans la matière du joint 34, lorsque celle-ci est coulée ou moulée, de sorte à former un moyen d'accrochage du dit joint 34. Les saillies sont venues de fabrication, par moulage, avec la capsule 3.In order to improve the retention of the seal 34 in the groove 30, and in particular to prevent that it does not escape from said groove 30 by an axial movement away from the wall transverse 5, the groove 30 is provided with projections intended to penetrate into the material of the joint 34, when the latter is cast or molded, so as to form a means for attaching said seal 34. The projections came from manufacture, by molding, with capsule 3.

Selon un premier mode de réalisation, illustré par la figure 4, chacune des deux nervures 31, 32 comprend une saillie annulaire 35, d'axe sensiblement confondu avec l'axe 4 de la capsule 3, s'étendant radialement vers l'intérieur de la gorge 30. L'invention prévoit également une réalisation dans laquelle les saillies 35 forment un angle aigu avec les nervures 31, 32. Les saillies 35 sont situées chacune vers la partie extrême libre d'une nervure 31, 32.According to a first embodiment, illustrated by FIG. 4, each of the two ribs 31, 32 comprises an annular projection 35, of axis substantially coincident with the axis 4 of the capsule 3, extending radially towards the inside of the groove 30. The invention also provides an embodiment in which the projections 35 form a acute angle with the ribs 31, 32. The projections 35 are each located towards the part free end of a rib 31, 32.

La hauteur axiale de chacune des saillies 35 va en diminuant depuis la nervure 31, 32 jusqu'à l'extrémité de la saillie 35, de sorte à former une pointe apte à pénétrer dans le joint 34.The axial height of each of the projections 35 decreases from the rib 31, 32 up to the end of the projection 35, so as to form a point capable of penetrating the seal 34.

Selon un deuxième mode de réalisation, illustré par la figure 5, le fond 36 de la gorge 30, sensiblement confondu avec la paroi transversale 5 de la capsule 3, comporte une saillie 37 dirigée vers l'intérieur de la gorge 30, sensiblement axialement.According to a second embodiment, illustrated in FIG. 5, the bottom 36 of the groove 30, substantially coincident with the transverse wall 5 of the capsule 3, has a projection 37 directed towards the inside of the groove 30, substantially axially.

La saillie 37 présente, en coupe axiale, la forme d'un trapèze, ou plutôt de deux trapèzes symétriques par rapport à l'axe 4 de la capsule 3.The projection 37 has, in axial section, the shape of a trapezoid, or rather of two symmetrical trapezoids with respect to the axis 4 of the capsule 3.

La petite base 38 du trapèze est sensiblement confondue avec le fond 36 de la gorge 30, la grande base 39 du trapèze constituant l'extrémité libre de la saillie 37. Le trapèze possède un axe de symétrie 40 sensiblement parallèle à l'axe 4 de la capsule 3. The small base 38 of the trapezoid is substantially coincident with the bottom 36 of the groove 30, the large base 39 of the trapezium constituting the free end of the projection 37. The trapezium has an axis of symmetry 40 substantially parallel to the axis 4 of the capsule 3.

Les faces du trapèze distinctes des bases 38, 39 sont inclinées par rapport au fond 36 de la gorge 30 d'un angle aigu, par exemple compris entre 40° et 80°, notamment voisin de 60°. La hauteur axiale de la saillie 37 est inférieure à celle des nervures 31, 32.The distinct trapezoid faces of the bases 38, 39 are inclined relative to the bottom 36 groove 30 at an acute angle, for example between 40 ° and 80 °, in particular neighboring 60 °. The axial height of the projection 37 is less than that of the ribs 31, 32.

Selon une réalisation non représentée, la saillie 37 présente, en coupe axiale, la forme d'un trapèze dont la grande base est sensiblement confondue avec le fond 36 de la gorge 30, la petite base du trapèze constituant l'extrémité libre de la saillie 37. La petite base peut être de longueur très petite, de sorte que le trapèze s'apparente à un triangle. Au moins une face du trapèze, distincte des bases, est inclinée par rapport au fond 36 de la gorge 30 d'un angle aigu, par exemple compris entre 40° et 80°, notamment voisin de 60°.According to an embodiment not shown, the projection 37 has, in axial section, the shape a trapezoid whose large base is substantially coincident with the bottom 36 of the groove 30, the small base of the trapezium constituting the free end of the projection 37. The small base can be very small in length, so that the trapezoid is like a triangle. At least one side of the trapezoid, distinct from the bases, is inclined relative to the bottom 36 groove 30 at an acute angle, for example between 40 ° and 80 °, in particular neighboring 60 °.

Selon une autre réalisation possible de l'invention, la face intérieure de la gorge 30 est pourvue de reliefs localisés formant moyens d'accrochage mécanique du joint 34.According to another possible embodiment of the invention, the inner face of the groove 30 is provided with localized reliefs forming mechanical attachment means of the seal 34.

Par exemple, la face intérieure de la gorge 30 comporte des stries, des écailles, des aspérités formées par électroérosion, ou équivalent. L'invention prévoit également de créer à l'intérieur de la gorge 30 un état de surface rugueux ou granité.For example, the inner face of the groove 30 has ridges, scales, roughness formed by EDM, or equivalent. The invention also provides create inside the groove 30 a rough surface or granite.

Dans le cas du coulage, la mise en place du joint 34 se fait par dépôt d'un certain volume de matière au fond de la gorge 30, la capsule 3 ayant été préalablement moulée par injection. Ce dépôt peut être effectué à partir d'une extrudeuse ou d'un pistolet à « hot melt ». La matière constitutive du joint 34, chaude et liquide, ou du moins pâteuse, s'étale sur le fond 36 de la gorge 30, enrobe et recouvre les saillies 35, 37.In the case of casting, the installation of the seal 34 is done by depositing a certain volume of material at the bottom of the groove 30, the capsule 3 having been previously molded by injection. This deposition can be carried out from an extruder or a spray gun. "Hot melt". The material of the seal 34, hot and liquid, or at least pasty, spreads over the bottom 36 of the groove 30, coats and covers the projections 35, 37.

On laisse généralement le joint 34 prendre sa forme géométrique naturelle, ce qui conduit à une surface bombée, comme illustrée sur la figure 3.The joint 34 is generally allowed to take its natural geometric shape, which leads to a curved surface, as illustrated in Figure 3.

La configuration des saillie 35, 37 est telle qu'il existe une zone 41 - dite zone d'accrochage - comprise axialement entre le fond 36 de la gorge 30 et la dite saillie 35, 37. Une partie de la matière déposée au fond du bouchon et s'écoulant contre le fond 36 de la gorge 30 vient se placer dans la zone d'accrochage 27. The configuration of the projections 35, 37 is such that there is a zone 41 - called zone attachment - axially between the bottom 36 of the groove 30 and said projection 35, 37. Part of the material deposited at the bottom of the stopper and flowing against the bottom 36 of the groove 30 is placed in the attachment zone 27.

Ainsi, en plus du collage physico-chimique du joint 34 coulé sur le fond 36 de la paroi gorge 30, il existe, du fait de la présence des saillies 35, 37 ou des reliefs de la face intérieure de la gorge 30, un accrochage mécanique du dit joint 34, une fois solidifié, qui l'empêche de se désolidariser de la dite gorge 30.Thus, in addition to the physicochemical bonding of the seal 34 cast on the bottom 36 of the wall groove 30, it exists, due to the presence of projections 35, 37 or of the reliefs of the face inside the groove 30, a mechanical attachment of said seal 34, once solidified, which prevents it from detaching from said groove 30.

En conséquence, malgré l'empilement des bonbonnes les unes sur les autres et les efforts qui en découlent au niveau du joint 34, ce dernier est maintenu en position contre la paroi transversale 5, à la fois parallèlement et perpendiculairement à celle-ci, grâce à la gorge 30 et aux saillies 35, 37, sans risque de rupture du joint 34.Consequently, despite the stacking of the cylinders on top of each other and the efforts resulting from the joint 34, the latter is held in position against the transverse wall 5, both parallel and perpendicular thereto, thanks to the groove 30 and the projections 35, 37, without risk of rupture of the seal 34.

On se réfère maintenant aux figures 8 et 9 qui illustrent une deuxième variante de réalisation de l'ensemble capsule 3 - joint 34, par moulage par bi-injection. Il est à noter que les figures sont simplifiées, les nervures 31, 32 et les saillies 35, 37 n'apparaissant pas.We now refer to FIGS. 8 and 9 which illustrate a second variant of production of the capsule 3 - seal 34 assembly, by bi-injection molding. Note that the figures are simplified, the ribs 31, 32 and the projections 35, 37 not appearing not.

Le joint 34 est tout d'abord injecté, entre une première partie de moule 42 et un noyau 43 qui définissent la forme du dit joint 34 (figure 8). La jonction entre la première partie de moule 42 et le noyau 43 est étanche.The seal 34 is first injected, between a first mold part 42 and a core 43 which define the shape of said seal 34 (Figure 8). The junction between the first part mold 42 and the core 43 is sealed.

Après un temps de refroidissement du joint 34, on injecte la capsule 3 entre une deuxième partie de moule 44 et le noyau 43, de sorte à surmouler le joint 34 (figure 9). Les saillies 35, 37 sont ainsi moulées à l'intérieur du joint 34, ce qui assure un bon accrochage du dit joint 34. La capsule 3 est par exemple réalisée en polyéthylène haute densité (HDPE).After the seal 34 has cooled down, the capsule 3 is injected between a second part of the mold 44 and the core 43, so as to overmold the seal 34 (FIG. 9). The projections 35, 37 are thus molded inside the seal 34, which ensures good attachment of said seal 34. The capsule 3 is for example made of high polyethylene density (HDPE).

Après un temps de refroidissement, l'ensemble capsule 3-joint 34 est éjecté du moule.After a cooling time, the 3-seal capsule assembly 34 is ejected from the mold.

Dans une variante de réalisation, les première et deuxième parties 42, 44 du moule présentent le même profil intérieur, de sorte que, à l'issue du refroidissement du joint 34 préalablement coulé, il suffit, sans ouvrir le moule, de déplacer la dite première ou deuxième partie 42, 44 par rapport au noyau 43, de façon à définir un logement dans lequel sera coulée la capsule 3. In an alternative embodiment, the first and second parts 42, 44 of the mold have the same internal profile, so that, after the seal 34 has cooled down previously cast, it suffices, without opening the mold, to move said first or second part 42, 44 relative to the core 43, so as to define a housing in which will be the capsule 3.

L'invention prévoit enfin un dispositif de bouchage simplifié (non représenté), muni de la gorge 30 et d'un joint 34 coulé ou moulé, dans lequel la capsule 3 ne comprend ni cheminée 7, ni bouchon 11, ni opercule 20, mais uniquement une jupe 6 pourvue d'une ligne de déchirure 23 dont une extrémité est située entre le bourrelet 8 et la paroi transversale 5, de sorte à permettre à un utilisateur d'ôter la capsule du col de la bonbonne par action sur la patte 24.The invention finally provides a simplified closure device (not shown), provided with the groove 30 and a seal 34 cast or molded, in which the capsule 3 does not include chimney 7, neither plug 11, nor cover 20, but only a skirt 6 provided with a tear line 23, one end of which is located between the bead 8 and the wall transverse 5, so as to allow a user to remove the capsule from the neck of the cylinder per action on tab 24.

Cette version simplifiée de bonbonne peut être mise en place sur un distributeur sans canule, très rapidement, de sorte à éviter toute aspersion d'eau. En revanche, si la bonbonne est retirée du distributeur avant d'être totalement vide, l'étanchéité n'est plus assurée.This simplified version of bottle can be installed on a dispenser without cannula, very quickly, so as to avoid any water spraying. However, if the bottle is removed from the dispenser before being completely empty, the seal is no longer assured.
