Description

La présente demande se rapporte à un robinet comprenant une canule démontable, plus particulièrement adapté pour prélever un échantillon de liquide plus ou moins chargé stocké dans un conteneur. Selon une application, un tel robinet est utilisé en tant que robinet de dégustation dans le domaine vinicole.The present application relates to a valve comprising a removable cannula, more particularly suitable for taking a sample of more or less charged liquid stored in a container. According to one application, such a tap is used as a tasting tap in the wine industry.

Selon un mode de réalisation connu et décrit dans le document WO2017187028 , un robinet de dégustation comprend :

  • un corps, configuré pour se fixer au niveau d'un orifice d'un conteneur, comportant des premier et deuxième trous traversants parallèles,
  • une canule démontable comportant une extrémité apte à s'emmancher dans le premier trou du corps,
  • une commande comportant une portion cylindrique montée pivotante dans le deuxième trou du corps, une poignée à une première extrémité de la portion cylindrique et un obturateur à une deuxième extrémité de la portion cylindrique, ladite commande étant configurée pour occuper un état fermé dans lequel l'obturateur obstrue entièrement le premier trou et un état ouvert dans lequel l'obturateur dégage le premier trou, la commande maintenant la canule emmanchée dans le premier trou à l'état ouvert.
According to a known embodiment described in the document WO2017187028 , a tasting faucet includes:
  • a body, configured to attach to an orifice of a container, comprising first and second parallel through holes,
  • a removable cannula having one end suitable for fitting into the first hole in the body,
  • a control comprising a cylindrical portion pivotally mounted in the second hole of the body, a handle at a first end of the cylindrical portion and a shutter at a second end of the cylindrical portion, said control being configured to occupy a closed state in which the obturator completely obstructs the first hole and an open state in which the obturator releases the first hole, the control maintaining the cannula fitted into the first hole in the open state.

Un tel robinet procure les avantages suivants :

  • Il limite les risques de contamination des échantillons, la canule pouvant être démontée et nettoyée entre deux prélèvements.
  • Il limite les risques d'obturation par des corps solides présents dans le liquide en raison du mouvement de pivotement de l'obturateur contre la paroi intérieure du corps,
  • Il est compatible avec les liquides alimentaires, toutes les pièces en contact avec le liquide étant en acier inoxydable de type alimentaire.
Such a valve provides the following advantages:
  • It limits the risk of sample contamination, as the cannula can be dismantled and cleaned between two samples.
  • It limits the risk of clogging by solid bodies present in the liquid due to the pivoting movement of the shutter against the inner wall of the body,
  • It is compatible with food liquids, all parts in contact with the liquid being made of food-grade stainless steel.

Malgré ces avantages, le robinet décrit dans le document WO2017187028 n'est pas pleinement satisfaisant pour les raisons suivantes :

  • Le corps a un diamètre extérieur supérieur à 20 mm si bien qu'il ne peut pas, sans les modifier, équiper les cuves existantes pourvues d'un manchon d'un diamètre intérieur de l'ordre de 18,63 mm.
  • La commande peut être manÅ“uvrée à l'état ouvert même en l'absence de canule.
Despite these advantages, the valve described in the document WO2017187028 is not fully satisfactory for the following reasons:
  • The body has an outside diameter greater than 20 mm so that it cannot, without modifying them, equip existing tanks provided with a sleeve with an inside diameter of the order of 18.63 mm.
  • The control can be operated in the open state even in the absence of a cannula.

Le document FR2491191 décrit un robinet pour un conteneur souple. Selon ce document, le robinet comprend :

  • un corps comportant un conduit traversant qui présente une extrémité interne orientée vers l'intérieur du conteneur souple et une extrémité externe orientée vers l'extérieur du conteneur souple,
  • un bouchon positionné à l'intérieur du conteneur souple, configuré pour s'emboîter au niveau de l'extrémité interne du conduit du corps et présentant une cavité centrale orientée vers l'extérieur du conteneur souple, et
  • une canule, configurée pour s'emmancher dans le conduit du corps, qui présente une extrémité interne configurée pour se loger dans la cavité centrale du bouchon.
The document FR2491191 describes a valve for a flexible container. According to this document, the valve includes:
  • a body comprising a through conduit which has an internal end oriented towards the interior of the flexible container and an external end oriented towards the exterior of the flexible container,
  • a plug positioned inside the flexible container, configured to fit at the inner end of the body conduit and having a central cavity facing outward from the flexible container, and
  • a cannula, configured to fit into the duct of the body, which has an internal end configured to be housed in the central cavity of the stopper.

Le bouchon comprend une arête périphérique extérieure configurée pour s'emboîter dans une encoche périphérique prévue au niveau de l'extrémité interne du conduit du corps. La canule comprend au niveau de son extrémité interne une arête périphérique extérieure configurée pour s'emboîter dans une gorge périphérique prévue au niveau de la cavité centrale du bouchon.The cap includes an outer peripheral ridge configured to fit into a peripheral notch provided at the inner end of the conduit of the body. The cannula comprises at its inner end an outer peripheral edge configured to fit into a peripheral groove provided at the level of the central cavity of the stopper.

Même si le robinet décrit dans le document FR2491191 peut se monter dans des manchons de petit diamètre, de l'ordre de 18,63 mm, il n'est pas pleinement satisfaisant car certaines pièces sont réalisées en matière plastique pour permettre au bouchon de pouvoir se clipser dans le conduit du corps ou à la canule de se clipser dans la cavité centrale du bouchon. Enfin, son fonctionnement n'est pas fiable car le bouchon peut ne pas se clipser à l'extrémité de la canule lorsque cette dernière est mise en place et tomber à l'intérieur du conteneur, rendant impossible la fermeture du robinet.Even if the valve described in the document FR2491191 can be mounted in small diameter sleeves, of the order of 18.63 mm, it is not fully satisfactory because certain parts are made of plastic material to allow the plug to be able to be clipped into the duct of the body or to the cannula to clip into the central cavity of the stopper. Finally, its operation is not reliable because the stopper may not clip onto the end of the cannula when the latter is put in place and fall inside the container, making it impossible to close the tap.

La présente invention vise à remédier à tout ou partie des inconvénients de l'art antérieur.The present invention aims to remedy all or part of the drawbacks of the prior art.

A cet effet, l'invention a pour objet un robinet permettant de contrôler l'écoulement d'un liquide d'une zone interne d'un conteneur vers une zone externe, ledit robinet comprenant :

  • un corps qui présente un alésage permettant de faire communiquer les zones interne et externe,
  • un bouchon mobile en translation, selon une direction de déplacement, entre une première position, correspondant à l'état fermé du robinet, dans laquelle le bouchon obture totalement l'alésage et une deuxième position, correspondant à l'état ouvert du robinet, dans laquelle le bouchon dégage au moins partiellement l'alésage, ledit bouchon présentant une première extrémité orientée vers la zone externe,
  • une canule qui s'étend entre une première extrémité et une deuxième extrémité qui présente une canalisation qui communique avec la zone interne lorsque la canule est reliée au bouchon et que le bouchon est dans la deuxième position,
  • un système d'accouplement, configuré pour relier les premières extrémités de la canule et du bouchon, comprenant une partie mâle solidaire d'une extrémité parmi les premières extrémités du bouchon et de la canule et une partie femelle solidaire de l'autre extrémité parmi les premières extrémités du bouchon et de la canule.
To this end, the subject of the invention is a valve making it possible to control the flow of a liquid from an internal zone of a container to an external zone, said valve comprising:
  • a body which has a bore making it possible to communicate the internal and external zones,
  • a stopper movable in translation, in a direction of movement, between a first position, corresponding to the closed state of the valve, in which the stopper completely closes the bore and a second position, corresponding to the open state of the valve, in which the plug at least partially clears the bore, said plug having a first end oriented towards the external zone,
  • a cannula which extends between a first end and a second end which has a channel which communicates with the internal zone when the cannula is connected to the stopper and the stopper is in the second position,
  • a coupling system, configured to connect the first ends of the cannula and the stopper, comprising a male part fixed to one end among the first ends of the stopper and the cannula and a female part fixed to the other end among the first ends of the stopper and the cannula.

Selon l'invention, les parties mâle et femelle du système d'accouplement sont configurées pour coopérer entre elles et permettre un emboîtement des parties mâle et femelle l'une dans l'autre selon une direction d'emboîtement, perpendiculaire à l'axe de l'alésage du corps, lorsque le bouchon (24) est dans la première position correspondant à l'état fermé, ainsi qu'une immobilisation des parties mâle et femelle l'une par rapport à l'autre selon la direction de déplacement lorsque les parties mâle et femelle sont accouplées.According to the invention, the male and female parts of the coupling system are configured to cooperate with each other and allow fitting of the male and female parts into each other according to a fitting direction, perpendicular to the axis of the bore of the body, when the plug (24) is in the first position corresponding to the closed state, as well as immobilization of the male and female parts relative to each other in the direction of movement when the male and female parts are mated.

Un tel robinet procure les mêmes avantages que le robinet de dégustation décrit dans le document WO2017187028 , tout en permettant un montage dans des orifices de petite section comme le robinet décrit dans le document FR2491191 .Such a tap provides the same advantages as the tasting tap described in the document WO2017187028 , while allowing assembly in small cross-section orifices such as the valve described in the document FR2491191 .

Sur les figures 1 et 2, on a représenté en 10 une paroi d'un conteneur qui délimite une zone interne Zint et une zone externe Zext et qui présente un orifice 12 permettant de faire communiquer les zones interne et externe Zint, Zext. Cet orifice 12 est délimité par une paroi cylindrique présentant un axe de révolution A12 et il débouche au niveau d'une face interne 10int, orientée vers la zone interne Zint, et d'une face externe 10ext orientée vers la zone externe Zext.On the figures 1 and 2 , there is shown at 10 a wall of a container which delimits an internal zone Zint and an external zone Zext and which has an orifice 12 allowing communication between the internal and external zones Zint, Zext. This orifice 12 is delimited by a cylindrical wall having an axis of revolution A12 and it opens out at an internal face 10int, oriented towards the internal zone Zint, and an external face 10ext oriented towards the external zone Zext.

Pour la suite de la description, une direction longitudinale est une direction parallèle à l'axe de révolution A12 de l'orifice 12. Un plan longitudinal est un plan qui passe par l'axe de révolution A12 de l'orifice 12. Un plan transversal est perpendiculaire à l'axe de révolution A12 de l'orifice 12.For the remainder of the description, a longitudinal direction is a direction parallel to the axis of revolution A12 of the orifice 12. A longitudinal plane is a plane which passes through the axis of revolution A12 of the orifice 12. A plane transverse is perpendicular to the axis of revolution A12 of the orifice 12.

Selon un mode de réalisation, le conteneur comprend un manchon qui traverse la paroi et qui délimite l'orifice 12. A titre indicatif et de manière non limitative, l'orifice 12 est un alésage taraudé et a un diamètre de l'ordre 18,63 mm.According to one embodiment, the container comprises a sleeve which passes through the wall and which delimits the orifice 12. By way of indication and in a non-limiting manner, the orifice 12 is a threaded bore and has a diameter of the order of 18, 63mm.

Selon une application, le conteneur est une cuve contenant du vin, du moût un liquide alimentaire ou tout autre liquide plus ou moins chargé.According to one application, the container is a tank containing wine, must, a food liquid or any other more or less loaded liquid.

Le conteneur est équipé d'un robinet 14 configuré pour occuper un état fermé, visible sur la figure 1, dans lequel il empêche tout écoulement de liquide de la zone interne Zint vers la zone externe Zext et un état ouvert, visible sur la figure 2, dans lequel il permet un écoulement de liquide de la zone interne Zint vers la zone externe Zext.The container is equipped with a valve 14 configured to occupy a closed state, visible on the figure 1 , in which it prevents any flow of liquid from the inner zone Zint to the outer zone Zext and an open state, visible on the picture 2 , in which it allows liquid flow from the inner zone Zint to the outer zone Zext.

Le robinet 14 comprend :

  • un corps 16 comportant une partie centrale 18 tubulaire qui présente un alésage 20, traversant, d'axe de révolution A20 (confondu avec l'axe de révolution A12 de l'orifice 12 lorsque le robinet est monté) ainsi qu'une paroi périphérique 22 cylindrique et coaxiale à l'alésage 20, ladite paroi périphérique 22 étant configurée pour coopérer avec l'orifice 12 de sorte que l'alésage 20 permette de faire communiquer les zones interne et externe Zint, Zext lorsque le robinet 14 est monté dans l'orifice 12 de la paroi 10 du conteneur,
  • un bouchon 24 mobile en translation, selon une direction de déplacement DD confondue avec l'axe de révolution A20, entre une première position, correspondant à l'état fermé, dans laquelle il obture totalement l'alésage 20 et une deuxième position, correspondant à l'état ouvert, dans laquelle il dégage, au moins partiellement, l'alésage 20, ledit bouchon 24 présentant une première extrémité 24.1 orientée vers la zone externe Zext et une deuxième extrémité 24.2 orientée vers la zone interne Zint,
  • une canule 26 tubulaire qui s'étend entre une première extrémité 26.1 configurée pour être reliée à la première extrémité 24.1 du bouchon 24 et une deuxième extrémité 26.2, ladite canule comportant une canalisation 28 qui débouche au niveau de ladite deuxième extrémité et qui communique avec la zone interne Zint lorsque la canule 26 est reliée au bouchon 24 et que ce dernier est dans la deuxième position correspondant à l'état ouvert.
Faucet 14 includes:
  • a body 16 comprising a tubular central part 18 which has a through bore 20 with an axis of revolution A20 (merges with the axis of revolution A12 of the orifice 12 when the valve is mounted) as well as a peripheral wall 22 cylindrical and coaxial with the bore 20, said peripheral wall 22 being configured to cooperate with the orifice 12 so that the bore 20 makes it possible to communicate the internal and external zones Zint, Zext when the valve 14 is mounted in the orifice 12 of the wall 10 of the container,
  • a stopper 24 movable in translation, in a direction of movement DD coinciding with the axis of revolution A20, between a first position, corresponding to the closed state, in which it completely closes the bore 20 and a second position, corresponding to the open state, in which it releases, at least partially, the bore 20, said plug 24 having a first end 24.1 oriented towards the external zone Zext and a second end 24.2 oriented towards the internal zone Zint ,
  • a tubular cannula 26 which extends between a first end 26.1 configured to be connected to the first end 24.1 of the stopper 24 and a second end 26.2, said cannula comprising a pipe 28 which opens at the level of said second end and which communicates with the inner zone Zint when cannula 26 is connected to stopper 24 and the latter is in the second position corresponding to the open state.

Selon un mode de réalisation visible sur les figures 3 à 5, la partie centrale 18 comprend une première face transversale 18.1 orientée vers la zone interne Zint et une deuxième face transversale 18.2 orientée vers la zone externe Zext. L'alésage 20 présente un chanfrein 30 au niveau de chacune de ses extrémités débouchant au niveau des première et deuxième faces transversales 18.1, 18.2.According to an embodiment visible on the figures 3 to 5 , the central part 18 comprises a first transverse face 18.1 oriented towards the internal zone Zint and a second transverse face 18.2 oriented towards the external zone Zext. The bore 20 has a chamfer 30 at each of its ends opening out at the level of the first and second transverse faces 18.1, 18.2.

Le robinet 14 comprend un système de liaison, pour relier le corps 16 et la paroi 10 du conteneur, et un système d'étanchéité entre le corps 16 et la paroi 10 du conteneur. Selon une configuration, le système de liaison comprend un filetage 32 au niveau de la paroi périphérique 22, configuré pour se visser dans l'alésage taraudé de l'orifice 12, et un épaulement 34, au niveau de la deuxième face transversale 18.2, configuré pour prendre appui contre la face externe 10ext de la paroi 10. Le système d'étanchéité présente une gorge 36 au niveau de la paroi périphérique 22, adjacente à l'épaulement 34, et un joint 38 (référencé sur la figure 1) positionné dans la gorge 36, configuré pour être comprimé entre le corps 16 et l'orifice 12 de la paroi 10 du conteneur.The valve 14 comprises a connection system, to connect the body 16 and the wall 10 of the container, and a sealing system between the body 16 and the wall 10 of the container. According to one configuration, the connection system comprises a thread 32 at the level of the peripheral wall 22, configured to be screwed into the tapped bore of the orifice 12, and a shoulder 34, at the level of the second transverse face 18.2, configured to bear against the outer face 10ext of the wall 10. The sealing system has a groove 36 at the level of the peripheral wall 22, adjacent to the shoulder 34, and a seal 38 (referenced on the figure 1 ) positioned in the groove 36, configured to be compressed between the body 16 and the orifice 12 of the wall 10 of the container.

Bien entendu, l'invention n'est pas limitée à ces modes de réalisation pour les systèmes de liaison et d'étanchéité entre l'orifice 12 de la paroi 10 et le robinet 14. De même, la paroi périphérique 22 du corps 16 peut ne pas être cylindrique.Of course, the invention is not limited to these embodiments for the connection and sealing systems between the orifice 12 of the wall 10 and the valve 14. Similarly, the peripheral wall 22 of the body 16 can not be cylindrical.

Selon une caractéristique de l'invention, le corps 16 comprend une gouttière interne 40, qui s'étend à partir de la première face transversale 18.1 de la partie centrale 18, et/ou une gouttière externe 42 qui s'étend à partir de la deuxième face transversale 18.2.According to one characteristic of the invention, the body 16 comprises an internal gutter 40, which extends from the first transverse face 18.1 of the central part 18, and/or an external gutter 42 which extends from the second transverse face 18.2.

Selon un mode de réalisation, la gouttière interne 40 est un demi-tube rectiligne et présente une face terminale 44 positionnée dans un plan transversal, deux chants latéraux 46, 46' positionnés dans un plan longitudinal, une face intérieure 48 cylindrique et orientée vers l'axe de révolution A20, ainsi qu'une face extérieure 50 opposée et coaxiale à la face intérieure 48.According to one embodiment, the internal gutter 40 is a straight half-tube and has an end face 44 positioned in a transverse plane, two side edges 46, 46' positioned in a longitudinal plane, a cylindrical inner face 48 oriented towards the axis of revolution A20, as well as an outer face 50 opposite and coaxial with the inner face 48.

La face intérieure 48 présente un premier tronçon 48.1, adjacent à la face terminale 44, qui a un diamètre sensiblement égal à celui de l'alésage 20 de la partie centrale 18, et un deuxième tronçon 48.2, adjacent à la première face transversale 18.1, qui a un diamètre supérieur à celui de l'alésage 20 de la partie centrale 18. Le premier tronçon 48.1 est configuré pour guider le bouchon 24, le deuxième tronçon 48.2 limitant les frottements entre le corps 16 et le bouchon 24.The inner face 48 has a first section 48.1, adjacent to the end face 44, which has a diameter substantially equal to that of the bore 20 of the central part 18, and a second section 48.2, adjacent to the first transverse face 18.1, which has a diameter greater than that of the bore 20 of the central part 18. The first section 48.1 is configured to guide the plug 24, the second section 48.2 limiting the friction between the body 16 and the plug 24.

La gouttière interne 40 comprend un pion 52 positionné au niveau de la face intérieure 48, plus précisément au niveau de son premier tronçon 48.1 dont la fonction sera détaillée ultérieurement.The internal gutter 40 comprises a pin 52 positioned at the level of the inner face 48, more precisely at the level of its first section 48.1, the function of which will be detailed later.

Selon un mode de réalisation, la gouttière externe 42 est une portion d'un tube rectiligne et présente une face terminale 54 positionnée dans un plan transversal, deux chants latéraux 56, 56' parallèle un plan longitudinal, une face intérieure 58 cylindrique et orientée vers l'axe de révolution A20, ainsi qu'une face extérieure 60 opposée et coaxiale à la face intérieure 58. La face intérieure 58 a un diamètre supérieur à celui de l'alésage 20 de la partie centrale 18.According to one embodiment, the outer gutter 42 is a portion of a rectilinear tube and has an end face 54 positioned in a transverse plane, two side edges 56, 56' parallel to a longitudinal plane, an inner face 58 which is cylindrical and oriented towards the axis of revolution A20, as well as an outer face 60 opposite and coaxial with the inner face 58. The inner face 58 has a diameter greater than that of the bore 20 of the central part 18.

Selon le mode de réalisation visible sur les figures 3 à 5, la gouttière externe 42 correspond à une portion légèrement inférieure à un demi-tube. En variante, la gouttière externe 42 peut avoir la forme d'un demi-tube. Dans tous les cas, la gouttière externe 42 est positionnée en partie inférieure de l'alésage 20 et présente une face intérieure 58 séparée de l'axe de révolution A20 de l'alésage 20 d'une distance très légèrement supérieure au diamètre de l'alésage 20.According to the embodiment visible on the figures 3 to 5 , the outer gutter 42 corresponds to a portion slightly smaller than a half-tube. Alternatively, the outer gutter 42 may have the shape of a half-tube. In all cases, the outer gutter 42 is positioned in the lower part of the bore 20 and has an inner face 58 separated from the axis of revolution A20 of the bore 20 by a distance very slightly greater than the diameter of the bore 20.

Selon une configuration, les gouttières interne et externe 40, 42 sont disposées du même côté d'un plan longitudinal PL, comme illustré sur la figure 5.According to one configuration, the internal and external gutters 40, 42 are arranged on the same side of a longitudinal plane PL, as illustrated in the figure 5 .

Selon une configuration visible sur la figure 9, la canule 26 présente deux tronçons, un premier tronçon rectiligne 62 adjacent à sa première extrémité 26.1 et un deuxième tronçon courbe 64 adjacent à sa deuxième extrémité 26.2.According to a configuration visible on the figure 9 , the cannula 26 has two sections, a first rectilinear section 62 adjacent to its first end 26.1 and a second curved section 64 adjacent to its second end 26.2.

Le premier tronçon rectiligne 62 de la canule 26 présente un diamètre extérieur sensiblement égal à celui de l'alésage 20 du corps 16, au jeu de montage près.The first rectilinear section 62 of the cannula 26 has an outside diameter substantially equal to that of the bore 20 of the body 16, except for assembly clearance.

Le robinet 14 comprend un système d'étanchéité entre le corps 16 et la canule 26 lorsque cette dernière est insérée dans l'alésage 20 du corps 16. Selon un mode de réalisation, ce système d'étanchéité comprend une gorge 66 prévue au niveau de la surface extérieure du premier tronçon rectiligne 62 de la canule 26, à proximité de la première extrémité 26.1 de la canule 26, et un joint 68 positionné dans la gorge 66, configuré pour être comprimé entre le corps 16 et la canule 26.The valve 14 comprises a sealing system between the body 16 and the cannula 26 when the latter is inserted into the bore 20 of the body 16. According to one embodiment, this sealing system comprises a groove 66 provided at the level of the outer surface of the first rectilinear section 62 of the cannula 26, close to the first end 26.1 of the cannula 26, and a seal 68 positioned in the groove 66, configured to be compressed between the body 16 and the cannula 26.

Selon un mode de réalisation visible sur les figures 6 et 7, le bouchon 24 a une forme approximativement cylindrique et présente un premier tronçon 70.1, proche de la première extrémité 24.1 du bouchon 24, qui a un diamètre extérieur sensiblement égal à celui de l'alésage 20 du corps 16, au jeu de montage près, ainsi qu'un deuxième tronçon 70.2 qui présente un premier méplat 72 parallèle à la direction longitudinale. Ce premier méplat 72 et le pion 52 de la gouttière interne 40 sont configurés pour permettre au bouchon 24 de se translater selon la direction de déplacement DD, entre les première et deuxième positions, lorsque le pion coïncide avec le premier méplat 72. Le premier méplat 72 comprend une première butée 73.1, contre laquelle le pion 52 prend appui lorsque le bouchon 24 est dans la première position, et une deuxième butée 73.2 contre laquelle le pion 52 prend appui lorsque le bouchon 24 est dans la deuxième position. Cette deuxième butée 73.2 est matérialisée par un épaulement.According to an embodiment visible on the figures 6 and 7 , the cap 24 has an approximately cylindrical shape and has a first section 70.1, close to the first end 24.1 of the cap 24, which has an outer diameter substantially equal to that of the bore 20 of the body 16, except for the assembly clearance, as well as a second section 70.2 which has a first flat 72 parallel to the longitudinal direction. This first flat 72 and the pin 52 of the internal gutter 40 are configured to allow the stopper 24 to translate in the direction of movement DD, between the first and second positions, when the pin coincides with the first flat 72. The first flat 72 comprises a first abutment 73.1, against which the pin 52 bears when the plug 24 is in the first position, and a second abutment 73.2 against which the pin 52 bears when the plug 24 is in the second position. This second stop 73.2 is materialized by a shoulder.

En complément du premier méplat 72, le bouchon 24 comprend une rainure 74, configurée pour loger le pion 52, positionnée à proximité de la deuxième extrémité 24.2 du bouchon 24, qui présente deux flancs 76, 76' positionnés dans deux plans transversaux et qui s'étend sur toute la périphérie du bouchon 24. Selon un mode de réalisation, le bouchon 24 présente, au niveau de sa deuxième extrémité 24.2, une réduction de diamètre délimitée par un épaulement 78 qui forme le premier flanc 76 de la rainure 74. Une vis 80, vissée dans un trou taraudé 82 prévu au niveau de la deuxième extrémité 24.2 du bouchon 24, comporte une tête 84 dont une face plaquée contre la face terminale transversale du bouchon 24, forme le deuxième flanc 76' de la rainure 74. D'autres solutions pourraient être envisagées pour former la rainure 74. La tête 84 forme également la première butée 73.1 qui matérialise la première position du bouchon 24.In addition to the first flat 72, the cap 24 comprises a groove 74, configured to house the pin 52, positioned near the second end 24.2 of the cap 24, which has two sides 76, 76 'positioned in two transverse planes and which are extends over the entire periphery of the stopper 24. According to one embodiment, the stopper 24 has, at its second end 24.2, a reduction in diameter delimited by a shoulder 78 which forms the first flank 76 of the groove 74. A screw 80, screwed into a threaded hole 82 provided at the level of the second end 24.2 of the cap 24, comprises a head 84, one face of which is pressed against the transverse end face of the stopper 24, forms the second flank 76' of the groove 74. Other solutions could be envisaged to form the groove 74. The head 84 also forms the first stop 73.1 which materializes the first position of the stopper 24.

Le pion 52 et la rainure 74 sont positionnés pour permettre au bouchon 24 de pivoter sur lui-même dans la première position correspondant à l'état fermé.The pin 52 and the groove 74 are positioned to allow the cap 24 to pivot on itself in the first position corresponding to the closed state.

Bien entendu, l'invention n'est pas limitée à ce mode de réalisation. Ainsi, le corps 16 et le bouchon 24 présentent des formes qui coopèrent de manière à limiter le mouvement de translation du bouchon 24 par rapport au corps 16 entre des première et deuxième butées 73.1, 73.2 qui correspondent respectivement aux première et deuxième positions. Selon une variante simplifiée, l'une des pièces parmi le corps 16 et le bouchon 24 comprend une forme en creux qui s'étend selon une direction parallèle à l'axe de révolution A20 de l'alésage 20 et qui présente, à une première extrémité, la première butée 73.1 et, à une deuxième extrémité, la deuxième butée 73.2, l'autre pièce parmi le corps 16 et le bouchon 24 comportant une forme en saillie configurée pour se déplacer dans la forme en creux. De préférence, la forme en creux du corps 16 ou du bouchon 24 comprend, au niveau de sa première extrémité, un prolongement qui s'étend selon une direction perpendiculaire à l'axe de révolution A20 de l'alésage 20 et qui permet d'immobiliser le bouchon 24 dans la première position lorsque la forme en saillie du bouchon 24 ou du corps 16 est positionnée dans ce prolongement.Of course, the invention is not limited to this embodiment. Thus, the body 16 and the stopper 24 have shapes which cooperate so as to limit the translational movement of the stopper 24 relative to the body 16 between first and second stops 73.1, 73.2 which correspond respectively to the first and second positions. According to a simplified variant, one of the parts among the body 16 and the cap 24 comprises a hollow shape which extends in a direction parallel to the axis of revolution A20 of the bore 20 and which has, at a first end, the first abutment 73.1 and, at a second end, the second abutment 73.2, the other part among the body 16 and the plug 24 comprising a protruding shape configured to move in the hollow shape. Preferably, the hollow shape of the body 16 or of the stopper 24 comprises, at its first end, an extension which extends in a direction perpendicular to the axis of revolution A20 of the bore 20 and which makes it possible to immobilize the stopper 24 in the first position when the projecting shape of the stopper 24 or of the body 16 is positioned in this extension.

Le robinet 14 comprend un système d'étanchéité entre le corps 16 et le bouchon 24 lorsque ce dernier est dans la première position, correspondant à l'état fermé. Selon un mode de réalisation, ce système d'étanchéité comprend une gorge 86 prévue au niveau du premier tronçon 70.1, à proximité de la première extrémité 24.1 du bouchon 24, et un joint 88 positionné dans la gorge 86, configuré pour être comprimé entre le corps 16 et le bouchon 24.The valve 14 comprises a sealing system between the body 16 and the plug 24 when the latter is in the first position, corresponding to the closed state. According to one embodiment, this sealing system comprises a groove 86 provided at the level of the first section 70.1, close to the first end 24.1 of the cap 24, and a seal 88 positioned in the groove 86, configured to be compressed between the body 16 and cap 24.

Selon une autre caractéristique, le robinet comprend un système d'accouplement 90 configuré pour relier le bouchon 24 et la canule 26.According to another characteristic, the tap comprises a coupling system 90 configured to connect the stopper 24 and the cannula 26.

Le système d'accouplement 90 comprend une partie mâle 90.1, visible sur la figure 10A, solidaire de la première extrémité 24.1 du bouchon 24 (ou de la première extrémité 26.1 de la canule 26) et une partie femelle 90.2, visible sur la figure 10B, solidaire de la première extrémité 26.1 de la canule 26 (ou de la première extrémité 24.1 du bouchon 24).The coupling system 90 comprises a male part 90.1, visible on the figure 10A , secured to the first end 24.1 of the stopper 24 (or to the first end 26.1 of the cannula 26) and a female part 90.2, visible on the figure 10B , secured to the first end 26.1 of the cannula 26 (or to the first end 24.1 of the stopper 24).

Les parties mâle et femelle 90.1 et 90.2 sont configurées pour coopérer entre elles et permettre un emboitement de la partie mâle 90.1 dans la partie femelle 90.2 selon une direction d'emboîtement DE, perpendiculaire à l'axe de révolution A20 de l'alésage 20 du corps 16, lorsque le bouchon 24 est dans la première position correspondant à l'état fermé, et une immobilisation des parties mâle et femelle 90.1, 90.2 l'une par rapport à l'autre selon la direction de déplacement DD, lorsque le bouchon 24 et la canule 26 se déplacent selon la direction de déplacement DD, dans le sens de l'insertion de la canule 26 dans l'alésage 20 du corps 16 ou dans le sens du retrait de la canule 26 de l'alésage 20.The male and female parts 90.1 and 90.2 are configured to cooperate with each other and allow interlocking of the male part 90.1 in the female part 90.2 according to an interlocking direction DE, perpendicular to the axis of revolution A20 of the bore 20 of the body 16, when the cap 24 is in the first position corresponding to the closed state, and immobilization of the male and female parts 90.1, 90.2 relative to each other in the direction of movement DD, when the cap 24 and the cannula 26 move in the direction of movement DD, in the direction of the insertion of the cannula 26 into the bore 20 of the body 16 or in the direction of the withdrawal of the cannula 26 from the bore 20.

Comme illustré sur la figure 2, la première extrémité 24.1 du bouchon 24 présente une face terminale transversale 24F et la première extrémité 26.1 de la canule 26 présente une face terminale transversale 26F.As illustrated on the figure 2 , the first end 24.1 of the plug 24 has a transverse end face 24F and the first end 26.1 of the cannula 26 has a transverse end face 26F.

Selon une première configuration visible sur la figure 9, la canalisation 28 débouche au niveau de la première extrémité 26.1 de la canule 26. En complément, la première extrémité 24.1 du bouchon 24 comprend un évidement 92 reliant la face terminale transversale 24F du bouchon 24 et la surface périphérique du premier tronçon 70.1 du bouchon 24 qui permet de prolonger la canalisation 28. Au niveau de la face terminale transversale 24F, l'évidement 92 a une section en U qui présente une portion courbe centrée par rapport au contour de la face terminale transversale 24F et deux branches espacées d'une distance sensiblement égale au diamètre de la canalisation 28 de la canule 26. Au niveau de la surface périphérique du premier tronçon 70.1, l'évidement 92 a également une section en U ouverte en direction de la face terminale transversale 24F du bouchon 24. Il est positionné diamétralement opposé au premier méplat 72, comme illustré en détails sur la figure 7.According to a first configuration visible on the figure 9 , the pipe 28 opens at the level of the first end 26.1 of the cannula 26. In addition, the first end 24.1 of the plug 24 comprises a recess 92 connecting the transverse end face 24F of the plug 24 and the peripheral surface of the first section 70.1 of the plug 24 which makes it possible to extend the pipe 28. At the level of the transverse end face 24F, the recess 92 has a U-shaped section which has a curved portion centered with respect to the contour of the transverse end face 24F and two branches spaced apart by a distance substantially equal to the diameter of the pipe 28 of the cannula 26. At the level of the peripheral surface of the first section 70.1, the recess 92 also has a U-shaped section open in the direction of the transverse end face 24F of the stopper 24. It is positioned diametrically opposite the first flat 72, as illustrated in detail on the figure 7 .

Bien entendu, d'autres géométries sont envisageables pour l'évidement 92 qui doit favoriser l'écoulement du liquide de la zone interne Zint vers la canalisation 28 de la canule 26.Of course, other geometries are possible for the recess 92 which must promote the flow of the liquid from the internal zone Zint towards the pipe 28 of the cannula 26.

Selon une autre configuration, la canalisation 28 comprend un orifice qui débouche au niveau de la surface extérieure du premier tronçon rectiligne 62 positionné dans la zone interne Zint, en dehors de l'alésage 20 du corps 16. Selon cette configuration, la première extrémité 24.1 du bouchon 24 ne comprend pas d'évidement 92.According to another configuration, the pipe 28 comprises an orifice which opens at the outer surface of the first rectilinear section 62 positioned in the internal zone Zint, outside the bore 20 of the body 16. According to this configuration, the first end 24.1 of the cap 24 does not include a recess 92.

Quelle que soit la configuration, le bouchon 24 et/ou la canule 26 comprennent un orifice débouchant dans la zone interne Zint, lorsque le bouchon est dans la deuxième position correspondant à l'état ouvert, et communiquant avec la canalisation 28 de la canule 26.Whatever the configuration, the stopper 24 and/or the cannula 26 comprise an opening opening into the internal zone Zint, when the stopper is in the second position corresponding to the open state, and communicating with the pipe 28 of the cannula 26 .

Un mode de réalisation du système d'accouplement 90 est visible sur les figures 8, 10A, 10B et 12. La partie mâle 90.1 comprend une rainure extérieure 94, écartée de la face terminale transversale 24F de la première extrémité 24.1 du bouchon 24, qui délimite avec la face terminale transversale 24F une collerette extérieure 96. En complément, le fond de la rainure extérieure 94 et/ou la collerette extérieure 96 présentent au moins un méplat. Selon un mode de réalisation visible sur la figure 12, le fond de la rainure extérieure 94 et la collerette extérieure 96 présentent chacun deux méplats 98, 98', 100, 100' diamétralement opposés, parallèles entre eux et perpendiculaires au premier méplat 72.An embodiment of the coupling system 90 is visible on the figures 8, 10A, 10B and 12 . The male part 90.1 comprises an outer groove 94, separated from the transverse end face 24F of the first end 24.1 of the plug 24, which delimits with the transverse end face 24F an outer collar 96. In addition, the bottom of the outer groove 94 and / or the outer flange 96 have at least one flat. According to an embodiment visible on the figure 12 , the bottom of the outer groove 94 and the outer collar 96 each have two diametrically opposed flats 98, 98', 100, 100', parallel to each other and perpendicular to the first flat 72.

Lorsque le bouchon 24 comprend un évidement 92, la rainure extérieure 94 et la collerette extérieure 96 ont une forme en U. En l'absence d'évidement 92, la rainure extérieure 94 et la collerette extérieure 96 peuvent être périphériques et s'étendre sur toute la périphérie du bouchon 24.When the stopper 24 comprises a recess 92, the outer groove 94 and the outer flange 96 have a U-shape. In the absence of a recess 92, the outer groove 94 and the outer flange 96 can be peripheral and extend over the entire periphery of the cap 24.

En complément, la partie femelle 90.2 comprend une découpe radiale 102 reliant la canalisation 28 et la surface extérieure du premier tronçon 62 de la canule 26 permettant l'insertion de la partie mâle 90.1. Cette découpe 102 est orientée diamétralement opposée au deuxième tronçon courbe 64, comme illustré sur la figure 9. En complément, la partie femelle 90.2 comprend une rainure intérieure 104, écartée de la face terminale transversale 26F de la première extrémité 26.1 de la canule 26, qui délimite avec la face terminale transversale 26F une collerette intérieure 106.In addition, the female part 90.2 comprises a radial cutout 102 connecting the pipe 28 and the outer surface of the first section 62 of the cannula 26 allowing the insertion of the male part 90.1. This cutout 102 is oriented diametrically opposite to the second curved section 64, as illustrated in the figure 9 . In addition, the female part 90.2 comprises an inner groove 104, spaced from the transverse end face 26F of the first end 26.1 of the cannula 26, which delimits with the transverse end face 26F an inner flange 106.

Les rainures extérieure et intérieure 94, 104 sont dimensionnées de manière à respectivement loger les collerettes intérieure et extérieure 106, 96 lorsque les parties mâle et femelle 90.1, 90.2 sont accouplées.The outer and inner grooves 94, 104 are dimensioned so as to accommodate the inner and outer collars 106, 96 respectively when the male and female parts 90.1, 90.2 are coupled.

Selon une variante simplifiée, la partie femelle 90.2 comprend un logement, configuré pour loger au moins partiellement la partie mâle 90.1, qui présente une découpe radiale 102 pour permettre l'insertion de la partie mâle 90.1 selon la direction d'introduction radiale, au moins l'une des parties parmi les parties mâle et femelle 90.1, 90.2 présentant au moins une forme en saillie configurée pour se loger dans une forme en creux de l'autre partie parmi les parties mâle et femelle 90.1, 90.2 de sorte à immobiliser les parties mâle et femelle 90.1, 90.2 l'une par rapport à l'autre selon la direction de déplacement DD lorsque les parties mâle et femelle 90.1, 90.2 sont accouplées à savoir lorsque la partie mâle 90.1 est positionnée dans le logement de la partie femelle 90.2.According to a simplified variant, the female part 90.2 comprises a housing, configured to at least partially house the male part 90.1, which has a radial cutout 102 to allow the insertion of the male part 90.1 along the radial insertion direction, at least one of the parts among the male and female parts 90.1, 90.2 having at least one projecting shape configured to be housed in a hollow shape of the other part among the male and female parts 90.1, 90.2 so as to immobilize the parts male and female 90.1, 90.2 relative to each other in the direction of movement DD when the male and female parts 90.1, 90.2 are coupled, namely when the male part 90.1 is positioned in the housing of the female part 90.2.

Bien entendu, l'invention n'est pas limitée à ces formes pour obtenir un accouplement entre la canule 26 et le bouchon 24.Of course, the invention is not limited to these forms to obtain a coupling between the cannula 26 and the stopper 24.

Le fond de la rainure intérieure 104 et/ou la collerette intérieure 106 présentent au moins un méplat qui coopère avec le ou les méplat(s) du fond de la rainure extérieure 94 et/ou de la collerette extérieure 96 afin d'immobiliser la canule 26 et le bouchon en rotation l'un par rapport à l'autre. Selon un mode de réalisation visible sur la figure 12, le fond de la rainure intérieure 104 et/ou la collerette intérieure 106 présentent chacun deux méplats 108, 108', 110, 110' diamétralement opposés, parallèles entre eux et au plan de courbure du deuxième tronçon courbe 64, lesdits méplats 108, 108', 110, 110' prévus au niveau de la partie femelle étant configurés pour coopérer avec les méplats 98, 98', 100, 100' de la partie mâle 90.1. cet agencement permet d'obtenir une immobilisation en rotation de la canule 26 par rapport au bouchon 24 lorsque ces deux éléments sont accouplés. Ainsi, lorsqu'ils sont accouplés, le pivotement de la canule 26 sur elle-même provoque le pivotement du bouchon 24 sur lui-même. Selon une configuration visible sur la figure 2, le deuxième tronçon courbe 64 est orienté dans la même direction que le premier méplat 72 du bouchon 24.The bottom of the inner groove 104 and/or the inner collar 106 have at least one flat which cooperates with the flat(s) of the bottom of the outer groove 94 and/or the outer collar 96 in order to immobilize the cannula 26 and the cap rotating relative to each other. According to an embodiment visible on the figure 12 , the bottom of the inner groove 104 and/or the inner flange 106 each have two diametrically opposed flats 108, 108', 110, 110', parallel to each other and to the plane of curvature of the second curved section 64, said flats 108, 108 ', 110, 110' provided at the female part being configured to cooperate with the flats 98, 98', 100, 100' of the male part 90.1. this arrangement makes it possible to obtain immobilization in rotation of the cannula 26 with respect to the stopper 24 when these two elements are coupled. Thus, when they are coupled, the pivoting of the cannula 26 on itself causes the pivoting of the stopper 24 on itself. According to a configuration visible on the figure 2 , the second curved section 64 is oriented in the same direction as the first flat 72 of the cap 24.

Bien entendu, l'invention n'est pas limitée à ces formes pour obtenir une immobilisation en rotation de la canule 26 par rapport au bouchon 24. Quel que soit le mode de réalisation, les parties mâle et femelle 90.1, 90.2 présentent des formes qui coopèrent de manière à immobiliser en rotation la canule 26 et le bouchon 24 l'un par rapport l'autre lorsque les parties mâle et femelle 90.1, 90.2 sont accouplées. Selon une variante simplifiée, la partie mâle 90.1 comprend au moins un méplat qui coopère avec au moins un méplat de la partie femelle, lorsque les parties mâle et femelle 90.1, 90.2 sont accouplées, de sorte à immobiliser en rotation la canule 26 et le bouchon 24 l'un par rapport l'autre.Of course, the invention is not limited to these shapes to obtain immobilization in rotation of the cannula 26 with respect to the stopper 24. Whatever the embodiment, the male and female parts 90.1, 90.2 have shapes which cooperate in such a way as to immobilize the cannula 26 and the stopper 24 in rotation relative to each other when the male and female parts 90.1, 90.2 are coupled. According to a simplified variant, the male part 90.1 comprises at least one flat which cooperates with at least one flat of the female part, when the male and female parts 90.1, 90.2 are coupled, so as to immobilize the cannula 26 and the stopper 24 in rotation relative to each other.

Quel que soit le mode de réalisation, la longueur du bouchon 24, la position de la rainure 74, la position du pion 52 sur la gouttière interne 40 sont déterminées de manière à ce que la partie mâle 90.1 (ou la partie femelle 90.2) soit positionnée en dehors de l'alésage 20, dans la zone externe Zext, lorsque le bouchon 24 est dans la première position correspondant à l'état fermé, comme illustré sur la figure 1. Dans cette première position, la partie mâle 90.1 du bouchon 24 est positionnée dans la gouttière externe 42.Whatever the embodiment, the length of the cap 24, the position of the groove 74, the position of the pin 52 on the internal gutter 40 are determined so that the male part 90.1 (or the female part 90.2) is positioned outside the bore 20, in the outer zone Zext, when the plug 24 is in the first position corresponding to the closed state, as illustrated in the figure 1 . In this first position, the male part 90.1 of the stopper 24 is positioned in the outer gutter 42.

Les joints 68 88, respectivement montés sur la canule 26 et le bouchon 24, sont espacés d'une distance inférieure à la longueur de l'alésage 20 du corps 16 entre les chanfreins 30 de manière à ce qu'au moins un des deux joints 68, 88 soit en contact avec l'alésage 20 du corps 16. En variante, le robinet 14 peut ne comprendre qu'un unique joint positionné dans une gorge prévue au niveau de l'alésage 20, en aval (selon le sens de l'écoulement du liquide) de l'orifice du bouchon 24 et/ou de la canule 26 qui débouche dans la zone interne Zint et qui communique avec la canalisation 28 de la canule 26.The seals 68 88, respectively mounted on the cannula 26 and the stopper 24, are spaced apart by a distance less than the length of the bore 20 of the body 16 between the chamfers 30 so that at least one of the two seals 68, 88 is in contact with the bore 20 of the body 16. Alternatively, the valve 14 may comprise only a single seal positioned in a groove provided at the level of the bore 20, downstream (in the direction of the flow) of the orifice of the stopper 24 and/or of the cannula 26 which opens into the internal zone Zint and which communicates with the pipe 28 of the cannula 26.

A l'exception des joints 38, 68, 88, toutes les autres pièces du robinet 14 sont réalisées en un matériau compatible avec les produits alimentaires, comme par exemple en acier inoxydable de type alimentaire.With the exception of seals 38, 68, 88, all the other parts of valve 14 are made of a material compatible with food products, such as, for example, food-grade stainless steel.

Le principe de fonctionnement du robinet 14 est maintenant décrit au regard des figures 1 à 2, 13A à 13E.The operating principle of valve 14 is now described with regard to the figures 1 to 2 , 13A to 13E .

Lorsque le robinet 14 est à l'état fermé, le bouchon 24 est positionné dans la première position et obture totalement l'alésage 20 du corps 16, comme illustré sur la figure 1. La partie mâle 90.1 du bouchon 24 est positionnée en dehors de l'alésage 20 du corps, dans la gouttière externe 42. Le pion 52 de la gouttière interne 40 est positionné dans la rainure 74 du bouchon 24 et n'est pas disposé au droit du premier méplat 72 du bouchon 24. La portion courbe de la forme en U de la collerette extérieure 96 de la partie mâle 90.1 est orientée vers le hautWhen the valve 14 is in the closed state, the plug 24 is positioned in the first position and completely closes the bore 20 of the body 16, as illustrated in the figure 1 . The male part 90.1 of the stopper 24 is positioned outside the bore 20 of the body, in the external gutter 42. The pin 52 of the internal gutter 40 is positioned in the groove 74 of the stopper 24 and is not arranged to the right of the first flat 72 of the plug 24. The curved portion of the U-shape of the outer flange 96 of the male part 90.1 is oriented upwards

Le premier méplat 72 n'étant pas disposé au droit du pion 52 de la gouttière interne 40, le bouchon 24 est bloqué dans la première position correspondant à l'état fermé et ne peut pas se translater dans la deuxième position correspondant à l'état ouvert. Compte tenu des formes de la première extrémité 24.1 du bouchon 24, il est très difficile, voire impossible, de faire pivoter le bouchon 24 sur lui-même pour pourvoir par la suite le translater dans la deuxième position correspondant à l'état ouvert. Cette configuration permet d'obtenir un fonctionnement sûr, le bouchon 24 ne pouvant pas être ouvert en raison d'une fausse manœuvre.Since the first flat 72 is not positioned in line with the pin 52 of the internal gutter 40, the plug 24 is blocked in the first position corresponding to the closed state and cannot be translated into the second position corresponding to the open state. Given the shapes of the first end 24.1 of the plug 24, it is very difficult, if not impossible, to pivot the plug 24 on itself in order to subsequently be able to translate it into the second position corresponding to the open state. This configuration makes it possible to obtain safe operation, the cap 24 not being able to be opened due to an incorrect operation.

Comme illustré sur la figure 13A, la canule 26 est positionnée de sorte que la découpe 102 de la partie femelle 90.2 soit orientée vers le bas en direction de la partie mâle 90.1 du bouchon 24. Le deuxième tronçon courbe 64 est orienté vers le haut.As illustrated on the Figure 13A , the cannula 26 is positioned so that the cutout 102 of the female part 90.2 is oriented downwards in the direction of the male part 90.1 of the stopper 24. The second curved section 64 is oriented upwards.

Comme illustré sur la figure 13B, la canule 26 est translatée selon la direction d'emboîtement DE jusqu'à ce que la partie mâle 90.1 du bouchon 24 soit positionnée dans la partie femelle 90.2 de la canule 26.As illustrated on the Figure 13B , the cannula 26 is translated in the fitting direction DE until the male part 90.1 of the stopper 24 is positioned in the female part 90.2 of the cannula 26.

La canule 26 est pivotée sur elle-même, autour de l'axe de révolution A20 de l'alésage 20, en prenant en main le deuxième tronçon courbe 64 et en l'orientant vers le bas, comme illustré sur la figure 13C. Ce mouvement de pivotement de la canule 26 provoque le pivotement du bouchon 24 grâce au système d'accouplement 90. Dès lors, la canule 26 ne peut plus être désaccouplée du bouchon 24, sans un nouveau mouvement de pivotement, car sa collerette intérieure 106 est bloquée dans la rainure extérieure 94 du bouchon 24 par la gouttière externe 42.The cannula 26 is pivoted on itself, around the axis of revolution A20 of the bore 20, taking the second curved section 64 in hand and directing it downwards, as illustrated in the figure 13C . This pivoting movement of the cannula 26 causes the pivoting of the stopper 24 thanks to the coupling system 90. Consequently, the cannula 26 can no longer be uncoupled from the stopper 24, without a new pivoting movement, because its inner collar 106 is blocked in the outer groove 94 of the plug 24 by the outer gutter 42.

Le pion 52 de la gouttière interne 40 étant au droit du premier méplat 72, la canule 26 peut être poussée à l'intérieur de l'alésage 20 de manière à translater, selon la direction de déplacement DD, le bouchon 24 de la première position vers la deuxième position, comme illustré sur la figure 13D.The pin 52 of the internal gutter 40 being in line with the first flat 72, the cannula 26 can be pushed inside the bore 20 so as to translate, according to the direction of displacement DD, the stopper 24 from the first position to the second position, as shown in the figure 13D .

Ce mouvement de translation est opéré jusqu'à ce que le pion 52 de la gouttière interne 40 soit en contact avec la deuxième butée 73.2 matérialisant la deuxième position du bouchon 24 et correspondant à l'état ouvert du robinet 14, comme illustré sur les figures 13E et 2. Dès lors le liquide peut s'écouler de la zone interne Zint vers la zone externe Zext via la canule 26.This translational movement is operated until the pin 52 of the internal gutter 40 is in contact with the second stop 73.2 materializing the second position of the stopper 24 and corresponding to the open state of the valve 14, as illustrated on the figures 13E and 2 . From then on, the liquid can flow from the inner zone Zint to the outer zone Zext via the cannula 26.

Pour arrêter l'écoulement, la canule 26 est tirée pour l'extraire de l'alésage 20. Pour démonter la canule 26, les étapes précédemment décrites sont reproduites dans l'ordre inverse.To stop the flow, the cannula 26 is pulled to extract it from the bore 20. To disassemble the cannula 26, the steps previously described are repeated in reverse order.

L'invention procure les avantages suivants :
Le robinet 14 peut être monté sur les conteneurs existants pourvus d'un orifice 12 avec une faible section, le corps 16 ne comportant qu'un seul alésage 20 traversant.The invention provides the following advantages:
The valve 14 can be mounted on existing containers provided with an orifice 12 with a small section, the body 16 having only one bore 20 through.

Il offre un mode de fonctionnement sûr, le bouchon 24 ne pouvant pas être ouvert par inadvertance. De plus, le pion 52 et la deuxième butée 73.2 empêchent la chute du bouchon 24 à l'intérieur du conteneur.It offers a safe mode of operation, the plug 24 cannot be opened inadvertently. In addition, pin 52 and second stop 73.2 prevent cap 24 from falling inside the container.

Il est compatible avec les produits alimentaires, les pièces le composant (à l'exception des joints) étant réalisées en acier inoxydable de type alimentaire.It is compatible with food products, the component parts (with the exception of seals) being made of food-grade stainless steel.

Il procure un mode de fonctionnement fiable, le mouvement de translation du bouchon 24 et de la canule 26 lors du passage à l'état fermé engendrant un effet de cisaillement d'éventuelles particules solides présentes au niveau de l'orifice du bouchon 24 et/ou de la canule 26 qui débouche dans la zone interne Zint lorsque le bouchon 24 est dans la deuxième position correspondant à l'état ouvert et qui communique avec la canalisation 28 de la canule 26.It provides a reliable mode of operation, the translational movement of the stopper 24 and of the cannula 26 during passage to the closed state generating a shearing effect of any solid particles present at the level of the orifice of the stopper 24 and/ or the cannula 26 which opens into the inner zone Zint when the stopper 24 is in the second position corresponding to the open state and which communicates with the pipe 28 of the cannula 26.

Enfin, il limite les risques de contamination des échantillons, la canule pouvant être démontée pour être nettoyée entre deux prélèvements.Finally, it limits the risks of contamination of the samples, the cannula can be dismantled to be cleaned between two samples.

    - a body (16) which has a bore (20) via which the internal and external regions (Zint, Zext) can communicate,
    - a stopper (24) that is able to move in translation, in a movement direction (DD), between a first position corresponding to the closed state of the tap, in which the stopper (24) entirely shuts the bore (20), and a second position corresponding to the open state of the tap, in which the stopper (24) at least partially frees the bore (20), said stopper (24) having a first end (24.1) that is oriented towards the external region (Zext),
    - a cannula (26) which extends between a first end (26.1) and a second end (26.2), said cannula (26) having a pipe (28) which communicates with the internal region (Zint) when the cannula (26) is connected to the stopper (24) and the stopper (24) is in the second position,
    - a coupling system (90) that is configured to connect the first ends (24.1, 26.1) of the stopper (24) and of the cannula (26), comprising a male part (90.1) that is secured to one of the first ends (24.1, 26.1) of the stopper (24) and of the cannula (26) and a female part (90.2) that is secured to the other of the first ends (24.1, 26.1) of the stopper (24) and of the cannula (26),
    characterized in that the male and female parts (90.1, 90.2) of the coupling system (90) are configured to cooperate with one another and to allow the male and female parts (90.1, 90.2) to nest one in the other in a nesting direction (DE) that is perpendicular to the axis (A20) of the bore (20) of the body (16), when the stopper (24) is in the first position corresponding to the closed state, and to allow the male and female parts (90.1, 90.2) to be immobilized relative to one another in the movement direction (DD) when the male and female parts (90.1, 90.2) are coupled together.
  2. Tap according to Claim 1, characterized in that the female part (90.2) comprises a recess, configured to accommodate at least some of the male part (90.1), which has a radial cutout (102) to permit insertion of the male part (90.1) in the nesting direction (DE), at least one of the male part and female part (90.1, 90.2) having at least a projecting shape that is configured to fit into a hollow shape of the other of the male part and female part (90.1, 90.2) so as to immobilize the male and female parts (90.1, 90.2) with respect to one another in the movement direction (DD) when the male and female parts (90.1, 90.2) are coupled together.
  3. Tap according to one of the preceding claims, characterized in that the male and female parts (90.1, 90.2) have shapes which cooperate so as to immobilize the cannula (26) and the stopper (24) in rotation with respect to one another when the male and female parts (90.1, 90.2) are coupled together.
  4. Tap according to the preceding claim, characterized in that the male part (90.1) comprises at least one flat (98, 98', 100', 100') which cooperates with at least one flat (108, 108', 110, 110') of the female part (90.2) when the male and female parts (90.1, 90.2) are coupled together, so as to immobilize the cannula (26) and the stopper (24) in rotation with respect to one another.
  5. Tap according to one of the preceding claims, characterized in that the body (16) and the stopper (24) have shapes which cooperate so as to limit the translational movement of the stopper (24) relative to the body (16) between first and second stops (73.1, 73.2) which respectively correspond to the first and second positions.
  6. Tap according to the preceding claim, characterized in that one of the parts among the body (16) and the stopper (24) comprises a hollow shape which extends in a direction parallel to the axis (A20) of the bore (20) and which has the first stop (73.1) at a first end and the second stop (73.2) at a second end, the other part among the body (16) and the stopper (24) comprising a projecting shape that is configured to move in the hollow shape.
  7. Tap according to the preceding claim, characterized in that the hollow shape of the body (16) or of the stopper (24) comprises, at its first end, an extension which extends along a first direction perpendicular to the axis (A20) of the bore (20) and which serves to immobilize the stopper (24) in the first position when the projecting shape of the stopper (24) or of the body (16) is positioned in this extension.
  8. Tap according to one of the preceding claims, characterized in that the body (16) comprises an internal gutter (40) which extends from a first transverse face (18.1) of the body, oriented towards the internal region (Zint), which is positioned in the lower part of the bore (20), which has a semicylindrical inside face (48) of which a first segment (48.1) has a diameter substantially equal to that of the bore (20) so as to guide the stopper (24), and which comprises a peg (52) positioned on the inside face (48), and in that the stopper (24) comprises a first flat (72) that is parallel to the axis (A20) of the bore (20) and is configured to accommodate the peg (52) of the internal gutter (40), the first flat (72) comprising a first stop (73.1) against which the peg (52) bears when the stopper (24) is in the first position, and a second stop (73.2) against which the peg (52) bears when the stopper (24) is in the second position.
  9. Tap according to the preceding claim, characterized in that the stopper (24) comprises a groove (74) that is configured to accommodate the peg (52), this extending over the entire periphery of the stopper (24), the peg (52) and the groove (74) being positioned so as to allow the stopper (24) to pivot on itself when in the first position.
  10. Tap according to the preceding claim, characterized in that the cannula (26) comprises a curved segment (64) that is oriented in the same direction as the first flat (72) of the stopper (24) when the cannula (26) and the stopper (24) are coupled together.
  11. Tap according to one of the preceding claims, characterized in that the body (16) comprises an external gutter (42) which extends from a second transverse face (18.2) of the body (16), oriented towards the external region (Zext), which is positioned in the lower part of the bore (20) and which has an inside face (58) that is separated from the axis (A20) of the bore (20) by a distance that is very slightly greater than the diameter of the bore (20).
