Description

L'invention concerne un dispositif étanche de vidange d'un réservoir, bidon ou autre récipient possédant un orifice de vidange circulaire de diamètre quelconque, ledit dispositif comprenant un embout tronconique d'adaptation sur ledit orifice et muni d'un évent, ainsi qu'une tuyauterie souple ou rigide.The invention relates to a sealed device for emptying a tank, canister or other container having a circular emptying orifice of any diameter, said device comprising a frustoconical end fitting on said orifice and provided with a vent, as well as flexible or rigid piping.

Habituellement, la vidange est effectuée au moyen d'un entonnoir, ce qui entraîne souvent des éclaboussures, des incidents de transvidage et des pertes de liquide, qui est parfois salissant et dangereux.Usually, the emptying is done by means of a funnel, which often leads to splashes, incidents of pouring and loss of liquid, which is sometimes dirty and dangerous.

On a également proposé (brevet US-A-3940036) d'utiliser un embout tronconique solidaire d'un tuyau, muni sur sa surface externe de séries de nervures coaxiales à l'embout dont la périphérie comporte en outre une rainure longitudinale formant évent. Si un tel dispositif s'adapte, comme un entonnoir, sur des orifices de diamètres variables, il présente cependant de graves inconvénients. L'inconvénient principal est un manque d'étanchéité dû au fait que les nervures ne peuvent assurer une étanchéité certaine qui est de toute manière fortement comprise par l'existence de la rainure externe. En outre, un tel dispositif se détache facilement du récipient lorsqu'on l'incline pour le vider, de sorte que les inconvénients décrits pour l'entonnoir se retrouvent avec un tel dispositif. De plus, l'ensemble indémontable de l'embout et du tuyau est encombrant, salissant et difficilement utilisable pour des matières très différentes.It has also been proposed (US-A-3940036) to use a frustoconical end piece integral with a pipe, provided on its external surface with series of ribs coaxial with the end piece, the periphery of which furthermore has a longitudinal groove forming a vent. If such a device fits, like a funnel, on orifices of variable diameters, it nevertheless has serious drawbacks. The main drawback is a lack of tightness due to the fact that the ribs cannot ensure a certain seal which is in any case strongly understood by the existence of the external groove. In addition, such a device is easily detached from the container when tilted to empty it, so that the drawbacks described for the funnel are found with such a device. In addition, the non-removable assembly of the end piece and the hose is bulky, dirty and difficult to use for very different materials.

On a également proposé un joint étanche pour bouteilles (brevet GB-A-2045730) muni de nervures annulaires souples en saillie sur un corps tubulaire, et pouvant recevoir un tube dans l'orifice central. Un tel joint étanche pour bouteille ne peut s'adapter à des diamètres différents et ne comporte pas d'évent.A seal has also been proposed for bottles (GB-A-2045730) provided with flexible annular ribs projecting from a tubular body, and capable of receiving a tube in the central orifice. Such a tight seal for a bottle cannot adapt to different diameters and does not have a vent.

Ce joint étanche pour bouteille est destiné au remplissage d'une bouteille et non à la vidange. Ce dispositif est conçu pour recevoir un tube d'alimentation et non de vidange ou un instrument de mesure optique, et c'est pour cela qu'il ne comporte pas d'évent. Car, dans le cas d'alimentation, l'évent ne sert à rien, le phénomène de dépression étant annulé.This tight seal for bottles is intended for filling a bottle and not for emptying. This device is designed to receive a supply tube and not a drain or an optical measuring instrument, and that is why it has no vent. Because, in the case of feeding, the vent is useless, the phenomenon of depression being canceled.

Le bouchon verseur pour bouteille décrit dans le brevet GB-A-821769 comporte sur sa périphérie des nervures à section triangulaire avec un tube- évent rapporté à l'intérieur de l'orifice central. Le but des stries à section triangulaire est d'obtenir un effet de cliquet sur le goulot de la bouteille et d'opposer une importante résistance à son retrait. Ces stries triangulaires n'admettent pas les défauts de géométrie de l'orifice circulaire, tel qu'une aspérité au plan de joint de fabrication ou ovalisation prononcée de l'orifice. Ce bouchon verseur n'est pas prévu pour se raccorder à un tuyau.The bottle pouring plug described in GB-A-821769 has on its periphery triangular section ribs with a vent tube attached to the inside of the central orifice. The purpose of triangular section streaks is to obtain a ratchet effect on the neck of the bottle and to offer significant resistance to its removal. These triangular striations do not admit the geometry faults of the circular orifice, such as a roughness to the plane of the manufacturing joint or pronounced ovalization of the orifice. This pouring plug is not intended to be connected to a pipe.

La présente invention vise à fournir un dispositif de vidange du type décrit à l'introduction qui ne présente pas les inconvénients des dispositifs connus.The present invention aims to provide a draining device of the type described in the introduction which does not have the drawbacks of known devices.

A cet effet, le dispositif selon l'invention est caractérisé par le fait que ledit embout est muni sur sa périphérie externe de lamelles circulaires souples, que l'évent est constitué par un évidement allongé de l'embout et communique avec l'extérieur uniquement par les deux extrémités de l'embout, et que la périphérie de l'embout opposée à l'extrémité de plus petit diamètre comporte un rétrécissement radial de fixation étanche de ladite tuyauterie souple ou rigide.To this end, the device according to the invention is characterized in that said end piece is provided on its outer periphery with flexible circular strips, that the vent is constituted by an elongated recess of the end piece and communicates with the outside only by the two ends of the end piece, and that the periphery of the end piece opposite to the end of smaller diameter comprises a radial narrowing of tight fixing of said flexible or rigid piping.

L'utilisation d'un embout tronconique muni de lamelles circulaires élastiques permet d'obtenir une fixation étanche et sûre sur des orifices de diamètres variés, l'espace entre les lamelles assurant un effet de succion ou de ventouse. La souplesse des lamelles permet une étanchéité parfaite et de remédier ainsi aux défauts de géométrie radiaux et axiaux de l'orifice circulaire du récipient à vidanger. L'évent complètement intégré dans le corps de l'embout empeche les fuites vers l'extérieur. La fixation démontable de la tuyauterie permet de réduire l'encombrement pour le transport et d'utiliser des tuyauterie très diverses avec le même embout.The use of a frustoconical tip provided with elastic circular lamellae makes it possible to obtain a tight and secure fixing on orifices of various diameters, the space between the lamellae ensuring a suction or suction cup effect. The flexibility of the slats allows perfect sealing and thus remedies the radial and axial geometry defects of the circular orifice of the container to be emptied. The completely integrated vent in the body of the nozzle prevents leaks to the outside. The removable fixing of the piping makes it possible to reduce the space requirement for transport and to use very diverse piping with the same end piece.

Selon une forme de réalisation de l'invention, l'embout avec ses lamelles, l'évent et le rétrécissement de fixation sont réalisés en une seule opération de moulage par injection d'une matière plastique.According to one embodiment of the invention, the end piece with its lamellae, the vent and the fastening shrinkage are produced in a single injection molding operation of a plastic material.

Selon une variante, l'embout est constitué d'une pièce intérieure comportant un manchon muni d'un trou longitudinal et prolongé par une saillie tubulaire, et d'une pièce extérieure en forme de tronc de cône creux dont la surface externe comporte lesdites lamelles, ladite pièce extérieure étant fixée par soudage, collage ou encliquetage sur ladite pièce intérieure en ménageant un volume creux communiquant avec ledit trou longitudinal et, à l'extrémité opposée, avec l'extérieur par un trou ménagé entre les pièces externe et interne. On obtient ainsi un embout plus léger et plus facile à injecter.According to a variant, the end piece consists of an inner part comprising a sleeve provided with a longitudinal hole and extended by a tubular projection, and of an outer part in the form of a hollow truncated cone, the outer surface of which comprises said lamellae. , said outer part being fixed by welding, gluing or snapping onto said inner part by providing a hollow volume communicating with said longitudinal hole and, at the opposite end, with the outside by a hole made between the external and internal parts. This results in a lighter and easier to inject nozzle.

De préférence, les lamelles circulaires forment une succession d'anneaux au moins trois fois plus hauts que larges et séparés par un vide environ deux fois aussi large que la largeur de chaque anneau, l'extrémité libre desdits anneaux étant enveloppée par un tronc de cône coaxial à l'embout et de même pente. L'effet de ventouse, donc l'étanchéité et le maintien de l'embout, sont ainsi renforcés.Preferably, the circular lamellae form a succession of rings at least three times higher than wide and separated by a void about twice as wide as the width of each ring, the free end of said rings being enveloped by a truncated cone. coaxial at the tip and with the same slope. The suction cup effect, therefore the tightness and the maintenance of the nozzle, are thus reinforced.

L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel:

  • - la figure 1 est une vue en coupe axiale d'un dispositif selon une première forme de réalisation de l'invention, et
  • - la figure 2 est analogue à la figure 1, pour une variante.

  • FIG. 1 is a view in axial section of a device according to a first embodiment of the invention, and
  • - Figure 2 is similar to Figure 1, for a variant.

Le dispositif de vidange selon l'invention comprend un embout tronconique 1 dont la surface externe est munie de lamelles circulaires souples 2. La disposition des lamelles et leurs dimensions sont telles qu'elles forment une succession d'anneaux au moins trois plus hauts que larges et séparés par un vide environ deux fois aussi large que la largeur de chaque anneau, l'extrémité libre desdits anneaux étant enveloppée par un tronc de cône coaxial à l'embout et de même pente.The emptying device according to the invention comprises a frustoconical end piece 1 whose external surface is provided with flexible circular strips 2. The arrangement of the strips and their dimensions are such that they form a succession of rings at least three higher than wide and separated by a vacuum about twice as wide as the width of each ring, the free end of said rings being enveloped by a truncated cone coaxial with the end piece and of the same slope.

L'embout 1 est muni d'un orifice axial 3 et comporte un rétrécissement radial 4 pour la fixation d'une tuyauterie 5 souple ou rigide, par vissage ou tout autre moyen assurant l'étanchéité même en cas de serrage imparfait. Dans l'embout 1 est ménagé un évent 6 qui ne communique avec l'extérieur qu'aux deux extrémités de l'embout 1.The end piece 1 is provided with an axial orifice 3 and has a radial narrowing 4 for fixing a flexible or rigid pipe 5, by screwing or any other means ensuring sealing even in the event of imperfect tightening. In the end piece 1 is provided a vent 6 which communicates with the outside only at the two ends of the end piece 1.

Dans la forme de réalisation de la figure 1, l'ensemble de l'embout 1, avec les lamelles 2, l'orifice 3, le rétrécissement 4 et l'évent 6 est moulé en une seule fois en une matière plastique assurant la souplesse des lamelles 2 et une certaine rigidité du reste de l'embout.In the embodiment of FIG. 1, the whole of the end piece 1, with the lamellae 2, the orifice 3, the narrowing 4 and the vent 6 is molded in one go in a plastic material ensuring flexibility lamellae 2 and a certain rigidity of the rest of the nozzle.

Dans la variante de la figure 2, l'embout 1 est constitué d'une pièce intérieure 7 et d'une pièce extérieure 8. La pièce intérieure 7 comprend un manchon 9 percé d'un trou longitudinal 10 et prolongé par une saillie tubulaire 11 possédant une rainure axiale 15, l'orifice 3 étant formé par l'intérieur du tube 11 et l'intérieur du manchon 9. La pièce extérieure 8 est formée par un tronc de cône creux et porte sur sa face extérieure les lamelles 2 et sur sa face intérieure un index 14.In the variant of FIG. 2, the end piece 1 consists of an internal part 7 and an external part 8. The internal part 7 comprises a sleeve 9 pierced with a longitudinal hole 10 and extended by a tubular projection 11 having an axial groove 15, the orifice 3 being formed by the interior of the tube 11 and the interior of the sleeve 9. The exterior part 8 is formed by a hollow truncated cone and carries on its exterior face the lamellas 2 and on its inner face an index 14.

Les pièces 7 et 8 sont solidarisées, par enclipsage dans l'exemple représenté, de manière à orienter la pièce 8 par son index 14 dans la rainure 15 et à laisser entre elles un espace vide 12 et un trou 13 ménagé entre les deux pièces 7 et 8.The parts 7 and 8 are secured, by clipping in the example shown, so as to orient the part 8 by its index 14 in the groove 15 and to leave between them an empty space 12 and a hole 13 formed between the two parts 7 and 8.
