Description

La présente invention concerne un dispositif de fixation d'une valve sur un récipient pressurisé et un récipient équipé d'un tel dispositif.The present invention relates to a device for fixing a valve on a pressurized container and a container equipped with such a device.

Pour assurer la distribution sous pression des liquides, on fixe une valve sur le récipient métallique destiné à recevoir le fluide à distribuer. La valve est, de façon connue, constituée par un pot ou corps de valve dans lequel est ménagé un canal d'éjection qui assure la sortie du liquide. Cette valve est généralement solidarisée de la partie supérieure du récipient (lorsque celui-ci est posé sur un fond) à l'aide d'une coupelle métallique, dont la fixation se fait par sertissage, soit sur le rebord supérieur du récipient, soit sur le rebord supérieur d'un dôme métallique fermant le récipient à sa partie supérieure. Il n'est cependant pas toujours possible d'utiliser une coupelle de sertissage : c'est le cas lorsqu'en raison de la hauteur nécessaire pour le sertissage, la valve serait trop surélevée ; c'est le cas, également, lorsque le récipient a une forme ovale en section horizontale car le diamètre de la coupelle de sertissage est trop voisin du petit axe de la section ovale dès que le récipient est de dimensions relativement réduites. On est donc contraint d'utiliser un autre système de fixation de valve. Le problème est alors de trouver un système, qui soit suffisamment efficace pour qu'il n'y ait pas de risque d'arrachage de la valve sous l'effet de la pression à l'intérieur du récipient.To ensure the distribution under pressure of the liquids, a valve is fixed on the metal container intended to receive the fluid to be distributed. The valve is, in known manner, constituted by a pot or valve body in which is formed an ejection channel which ensures the exit of the liquid. This valve is generally secured to the upper part of the container (when the latter is placed on a bottom) using a metal cup, the fixing of which is by crimping, either on the upper rim of the container, or on the upper rim of a metal dome closing the container at its upper part. However, it is not always possible to use a crimping cup: this is the case when, because of the height necessary for crimping, the valve is too raised; this is also the case when the container has an oval shape in horizontal section because the diameter of the crimping cup is too close to the minor axis of the oval section as soon as the container is of relatively small dimensions. We are therefore forced to use another valve fixing system. The problem is then to find a system which is sufficiently effective so that there is no risk of the valve being torn off under the effect of the pressure inside the container.

La présente invention concerne un dispositif de fixation d'une valve de distribution, dont le pot de valve comporte, à sa partie supérieure, une collerette débordante, sur un récipient métallique destiné à contenir un fluide pressurisé, ledit récipient ayant une bordure supérieure de fixation de la valve constituée par un bourrelet annulaire de tôle roulée faisant saillie vers l'extérieur du récipient, le dispositif de fixation comportant une coupelle annulaire, en matière plastique, munie de moyens d'encliquetage destinés à s'insérer sous le bourrelet de fixation du récipient, de moyens d'emboîtage de la collerette du pot de valve, au moins la zone centrale de ladite collerette n'étant pas recouverte par lesdits moyens d'emboîtage, et une bague entourant la coupelle.The present invention relates to a device for fixing a dispensing valve, the valve pot of which comprises, at its upper part, an overflowing flange, on a metal container intended to contain a pressurized fluid, said container having an upper border for fixing the valve constituted by an annular bead of rolled sheet protruding towards the outside of the container, the fixing device comprising an annular cup, made of plastic, provided with latching means intended to be inserted under the flange for fixing the container, means for fitting the flange of the valve pot, at least the central zone of said flange not being covered by said fitting means, and a ring surrounding the cup.

Des dispositifs de fixation ont déjà été décrits, comme, par exemple, dans DE-A-2 013 178 : malheureusement, ou bien le bourrelet annulaire fait saillie à l'intérieur du récipient, en sorte que les moyens d'encliquetage sont côté intérieur du récipient, ou bien la bordure de fixation est rapportée à l'intérieur du col du récipient, en sorte que l'ouverture du récipient doit être de taille suffisante, d'autant plus que les moyens d'emboîtage sont, eux aussi, au droit de ladite ouverture.Fixing devices have already been described, such as, for example, in DE-A-2 013 178: unfortunately, either the annular bead protrudes inside the container, so that the latching means are on the inside of the container, or else the fixing edge is attached to the inside of the neck of the container, so that the opening of the container must be of sufficient size, all the more so since the casing means are also at right of said opening.

La solidarisation, donc l'étanchéité, est mieux assurée si l'on empêche les moyens d'encliquetage de s'éloigner du bourrelet de fixation du récipient, compte-tenu de la matière, plastique, dont est constituée la coupelle ; on a déjà proposé de rigidifier l'encliquetage en disposant une bague autour de la coupelle : c'est le cas, par exemple, des dispositions décrites dans FR-A-2508136, mais, le récipient est en aluminium filé et présente un bourrelet de fixation de section rectangulaire et, là encore, même si les dispositions décrites sont efficaces, les moyens d'emboîtage de la collerette du pot de valve sont au droit de l'ouverture délimitée par le bourrelet annulaire du récipient, et, par conséquent, la taille des récipients pressurisés auxquels ces dispositions sont applicables, et notamment la taille et la forme de leur section horizontale, ne peut pas être quelconque.The connection, therefore the sealing, is better ensured if the latching means are prevented from moving away from the retaining flange of the container, taking into account the material, plastic, of which the cup is made; it has already been proposed to stiffen the latching by placing a ring around the cup: this is the case, for example, of the arrangements described in FR-A-2508136, but, the container is made of spun aluminum and has a bead of fixing of rectangular section and, here again, even if the arrangements described are effective, the means for fitting the flange of the valve pot are in line with the opening delimited by the annular bead of the container, and, consequently, the size of the pressurized receptacles to which these provisions are applicable, and in particular the size and shape of their horizontal section, cannot be any.

Ainsi, la présente invention concerne un dispositif de fixation d'une valve de distribution, dont le pot de valve comporte, à sa partie supérieure, une collerette débordante, sur un récipient métallique destiné à contenir un fluide pressurisé, ledit récipient ayant une bordure supérieure de fixation de la valve constituée par un bourrelet annulaire de tôle roulée faisant saillie vers l'extérieur du récipient, le dispositif de fixation comportant une coupelle annulaire, en matière plastique, munie de moyens d'encliquetage destinés à s'insérer sous le bourrelet de fixation du récipient et de moyens d'emboîtage de la collerette du pot de valve, au moins la zone centrale de ladite collerette n'étant pas recouverte par les dits moyens d'emboîtage, une bague entourant la coupelle, caractérisé par le fait que la coupelle annulaire a une section radiale en forme de U, dont l'âme est disposée vers le récipient et dont les branches ont leurs lignes moyennes sensiblement parallèles à l'axe du récipient, la branche intérieure du U étant plus longue que la branche extérieure, la branche intérieure de ladite section radiale correspondant à une jupe intérieure, la branche extérieure à une jupe extérieure coaxiale à la première et l'âme du U à une platine annulaire, ladite jupe intérieure étant munie, sur sa face tournée vers l'axe, d'une part, au voisinage de la platine annulaire, desdits moyens d'encliquetage et, d'autre part, à son extrémité opposée, desdits moyens d'emboîtage de la collerette du pot de valve, la jupe extérieure comportant, sur sa face externe, un pas de vis, et en ce que la bague entourant la coupelle comporte, sur sa face interne, un pas de vis correspondant au pas de vis de la jupe extérieure de la coupelle.Thus, the present invention relates to a device for fixing a dispensing valve, the valve pot of which comprises, at its upper part, an overflowing flange, on a metal container intended to contain a pressurized fluid, said container having an upper edge. for fixing the valve constituted by an annular bead of rolled sheet protruding towards the outside of the container, the fixing device comprising an annular cup, made of plastic, provided with latching means intended to be inserted under the bead of fixing the container and means for fitting the flange of the valve pot, at least the central zone of said flange not being covered by the said casing means, a ring surrounding the cup, characterized in that the annular cup has a U-shaped radial section, the core of which is arranged towards the container and the branches of which have their mean lines substantially parallel to the axis of the container, the inner branch of the U being longer than the outer branch, the inner branch of said radial section corresponding to an inner skirt, the outer branch to an outer skirt coaxial with the first and the core of the U to an annular plate, said inner skirt being provided, on its face turned towards the axis, on the one hand, in the vicinity of the annular plate, of said latching means and, on the other hand, at its opposite end, said means for fitting the flange of the valve pot, the outer skirt comprising, on its outer face, a thread, and in that the ring surrounding the cup comprises, on its inner face, a thread corresponding to the thread of the outer skirt of the cup.

De préférence, le dispositif comporte un système autobloquant dont un élément est porté par la bague, et l'autre par la coupelle plastique. Ce système peut être constitué par des dents d'encliquetage portées, d'une part, par la bague et, d'autre part, par la face externe de la jupe intérieure de la coupelle plastique.Preferably, the device comprises a self-locking system, one element of which is carried by the ring, and the other by the plastic cup. This system can be constituted by snap-fit teeth carried, on the one hand, by the ring and, on the other hand, by the external face of the internal skirt of the plastic cup.

Les moyens d'emboîtage de la collerette du pot de valve sont constitués par un plateau annulaire perpendiculaire à l'axe reposant sur la face supérieure de la collerette du pot de valve et d'un bourrelet, de préférence continu, destiné à s'insérer sous la collerette du pot de valve.The means for fitting the flange of the valve pot consist of an annular plate perpendicular to the axis resting on the upper face of the flange of the valve pot and a bead, preferably continuous, intended to be inserted under the flange of the valve pot.

Le dispositif de fixation selon l'invention ne risque pas d'être arraché. En effet, le pot de valve est bloqué entre la coupelle et le récipient grâce aux moyens d'emboîtage de la partie supérieure du pot de valve et grâce aux moyens d'encliquetage sous le bourrelet annulaire de tôle roulée. De plus, la coupelle plastique est frettée par la bague, qui, lorsqu'elle est vissée, empêche tout évasement de la partie de la jupe intérieure, qui porte les moyens d'encliquetage, et assure donc le maintien du pot de valve sur le récipient. Le dévissage de la bague est évité grâce à un système autobloquant constitué, par exemple, d'ailettes radiales portées d'une part, par le bague et, d'autre part, par la collerette.The fixing device according to the invention does not risk being torn off. Indeed, the valve pot is blocked between the cup and the container by means of fitting the upper part of the valve pot and by means of latching under the annular bead of rolled sheet. In addition, the plastic cup is hooped by the ring, which, when screwed, prevents any flaring of the part of the inner skirt, which carries the latching means, and therefore ensures the maintenance of the valve pot on the container. The unscrewing of the ring is avoided thanks to a self-locking system consisting, for example, of radial fins carried on the one hand, by the ring and, on the other hand, by the flange.

Selon la présente invention, un joint d'étanchéité annulaire est, de préférence, disposé dans un logement ménagé sur la face supérieure de la collerette du pot de valve et il s'appuie sur les moyens d'emboîtage portés par la coupelle : ce joint permet d'obtenir l'étanchéité entre le pot de valve et la coupelle. De plus, on prévoit également un joint entre le bourrelet de fixation du récipient et les moyens d'emboîtage de la coupelle pour assurer l'étanchéité entre l'intérieur du récipient et la coupelle. On assure ainsi parfaitement l'étanchéité de l'obturation autour du pot de valve.According to the present invention, an annular seal is preferably placed in a housing formed on the upper face of the flange of the valve pot and it is supported by the fitting means carried by the cup: this seal provides a seal between the valve pot and the cup. In addition, a seal is also provided between the bead for fixing the container and the cup fitting means for sealing between the interior of the container and the cup. This ensures perfect sealing of the shutter around the valve pot.

De préférence, au moins une partie du filetage bague/coupelle est légèrement conique, l'angle au sommet du cône étant compris entre 1 et 5° et le sommet du cône étant situé du côté de la bague où ne se trouve pas le récipient. On améliore ainsi le serrage de la coupelle sur le pot de valve et le récipient.Preferably, at least part of the ring / cup thread is slightly conical, the angle at the top of the cone being between 1 and 5 ° and the top of the cone being located on the side of the ring where the container is not located. This improves the tightening of the cup on the valve pot and the container.

La description donnée ci-dessous à titre purement indicatif et non limitatif, ainsi que le dessin annexé permettront de mieux comprendre l'invention. Sur ce dessin :

  • la figure 1 est une vue en coupe diamétrale d'un dispositif de fixation de valve selon l'invention mis en place sur un récipient, le pot de valve n'étant que partiellement coupé ;
  • la figure 2 est une vue agrandie du détail A de la figure 1.
The description given below for purely indicative and not limiting, as well as the appended drawing will allow a better understanding of the invention. On this drawing :
  • Figure 1 is a diametrical sectional view of a valve fixing device according to the invention placed on a container, the valve pot being only partially cut;
  • FIG. 2 is an enlarged view of detail A of FIG. 1.

Le dispositif de fixation représenté sur le dessin est monté sur un récipient pressurisé 1 fermé à sa partie supérieure par un dôme métallique 2 et muni d'une valve 3. Ce dispositif de fixation comporte une coupelle 4 entourée par une bague 5 et munie de deux joints 6 et 7.The fixing device shown in the drawing is mounted on a pressurized container 1 closed at its upper part by a metal dome 2 and provided with a valve 3. This fixing device comprises a cup 4 surrounded by a ring 5 and provided with two seals 6 and 7.

Le dôme métallique 2 est serti par un bourrelet de sertissage 21 sur le bord supérieur du récipient 1 destiné à contenir le fluide sous pression à distribuer; il est muni à son sommet d'une ouverture circulaire 22 centrée sur l'axe du récipient 1. Cette ouverture 22 est délimitée par une cheminée cylindrique 11, dont la bordure supérieure porte un bourrelet de fixation 23 faisant saillie vers l'extérieur du récipient 1 ; ce bourrelet 23 est obtenu en roulant vers l'extérieur le bord de la tôle métallique formant la cheminée 11.The metal dome 2 is crimped by a crimping bead 21 on the upper edge of the container 1 intended to contain the pressurized fluid to be dispensed; it is provided at its top with a circular opening 22 centered on the axis of the container 1. This opening 22 is delimited by a cylindrical chimney 11, the upper edge of which carries a fixing bead 23 projecting towards the outside of the container 1; this bead 23 is obtained by rolling the edge of the metal sheet forming the chimney 11 outward.

La valve 3 est disposée dans l'axe de l'ouverture 22 ; elle comporte un pot de valve 32 dans lequel est monté, en translation selon l'axe, un tube de sortie 31 pour l'éjection du fluide à distribuer. Le pot de valve 32 est muni, à sa partie supérieure, d'une collerette débordante 33 dont la face supérieure est située dans un plan perpendiculaire à l'axe de la valve.The valve 3 is arranged in the axis of the opening 22; it comprises a valve pot 32 in which is mounted, in translation along the axis, an outlet tube 31 for the ejection of the fluid to be dispensed. The valve pot 32 is provided, at its upper part, with an overflowing flange 33, the upper face of which is situated in a plane perpendicular to the axis of the valve.

La coupelle annulaire 4 a, en section radiale, la forme d'un U comportant deux branches, une branche interne et une branche externe, correspondant respectivement à des jupes annulaires concentriques 41 et 42. La partie supérieure de la jupe interne 41 comporte, sur sa face interne tournée vers la valve 3, des moyens d'emboîtage de la collerette 33 du corps de valve 32. Ces moyens sont constitués d'un plateau annulaire 43 perpendiculaire à l'axe de la valve 3 qui vient s'appliquer sur la face supérieure plane de la collerette 33 du corps de valve et d'un bourrelet 44 qui vient s'engager sous cette collerette 33. Le plateau 43 comporte une ouverture centrale pour le passage du tube 31. A la partie inférieure de sa face interne, la jupe interne 41 de la coupelle 4 comporte un jonc annulaire continu 45, qui est engagé sous le bourrelet de fixation 23 du dôme 2 et qui constitue un moyen d'encliquetage de la coupelle 4 sur le dôme 2. La jupe interne 41 est également munie à sa partie supérieure, sur sa face externe, de dents de blocage 46. La jupe externe 42 de la coupelle 4 comporte, sur sa face externe, un pas de vis faiblement conique 47 (conicité d'environ 2°).The annular cup 4 has, in radial section, the shape of a U comprising two branches, an internal branch and an external branch, corresponding respectively to concentric annular skirts 41 and 42. The upper part of the internal skirt 41 comprises, on its internal face turned towards the valve 3, means for fitting the flange 33 of the valve body 32. These means consist of an annular plate 43 perpendicular to the axis of the valve 3 which is applied to the flat upper face of the flange 33 of the valve body and of a bead 44 which engages under this flange 33. The plate 43 has a central opening for the passage of the tube 31. At the lower part of its internal face, the internal skirt 41 of the cup 4 comprises a continuous annular ring 45, which is engaged under the fixing flange 23 of the dome 2 and which constitutes a means of snap-fastening of the cup 4 on the dome 2. The internal skirt 41 is also provided at its p upper part, on its outer face, of locking teeth 46. The outer skirt 42 of the cup 4 has, on its outer face, a slightly conical screw pitch 47 (taper of approximately 2 °).

La bague annulaire 5 entoure la coupelle 4. Elle comprend une première partie légèrement conique 51, l'angle au sommet du cône étant d'environ 2° ; cette partie 51 a la même hauteur que la jupe externe 42 de la coupelle 4 et porte sur sa face interne un pas de vis 52 coopérant avec le pas de vis 47 de la coupelle. Au-dessus de la partie 51 se trouve une collerette annulaire 53 située dans un plan perpendiculaire à l'axe de la valve, collerette qui repose sur le bord supérieur de la jupe 42 de la coupelle 4 lorsque la bague 5 est vissée à fond sur la coupelle 4. La collerette 53 porte un manchon cylindrique 54 se terminant par un anneau 55 perpendiculaire à l'axe de la valve 3. Sur la face interne du manchon cylindrique 54 et de l'anneau 55 sont fixées des dents de blocage 56 qui coopèrent avec les dents de blocage 46 de la coupelle 4. Les faces supérieures de l'anneau 55 de la bague de fixation et du plateau annulaire 43 de la coupelle 4 sont disposées sensiblement dans un même plan perpendiculaire à l'axe de la valve quand la bague 5 est vissée à fond sur la coupelle 4.The annular ring 5 surrounds the cup 4. It comprises a first slightly conical part 51, the angle at the top of the cone being approximately 2 °; this part 51 has the same height as the external skirt 42 of the cup 4 and carries on its internal face a thread 52 cooperating with the thread 47 of the cup. Above part 51 is an annular flange 53 located in a plane perpendicular to the valve axis, a flange which rests on the upper edge of the skirt 42 of the cup 4 when the ring 5 is fully screwed on the cup 4. The collar 53 carries a cylindrical sleeve 54 ending in a ring 55 perpendicular to the axis of the valve 3. On the internal face of the cylindrical sleeve 54 and of the ring 55 are fixed locking teeth 56 which cooperate with the locking teeth 46 of the cup 4. The upper faces of the ring 55 of the ring attachment and of the annular plate 43 of the cup 4 are arranged substantially in the same plane perpendicular to the axis of the valve when the ring 5 is screwed fully onto the cup 4.

Un joint annulaire 6 est disposé dans un logement 34 ménagé sur la face supérieure de la collerette 33 du corps de valve 32 et il est comprimé par le plateau annulaire de la coupelle 4. Un second joint annulaire 7 est disposé entre le pot de valve 32 et la face intérieure de la jupe interne 41 de la coupelle 4: il est comprimé entre le bourrelet de fixation 23 du dôme 22, d'une part, et le bourrelet 44 et la collerette 33, d'autre part.An annular seal 6 is disposed in a housing 34 formed on the upper face of the flange 33 of the valve body 32 and it is compressed by the annular plate of the cup 4. A second annular seal 7 is disposed between the valve pot 32 and the inner face of the internal skirt 41 of the cup 4: it is compressed between the fixing bead 23 of the dome 22, on the one hand, and the bead 44 and the collar 33, on the other hand.

Pour monter ce dispositif de fixation, on met en place le joint 6 dans le logement 34 ménagé sur la collerette 33 du pot de valve 32 et le joint 7 autour du pot de valve mais au-dessous de la collerette 33. On introduit alors la coupelle 4 autour de la valve 2 en emboîtant la collerette 33 du corps de valve 32 entre le plateau 43 et le bourrelet supérieur 44 de la jupe intérieure 41 de la coupelle 4. Le tube de sortie 31 traverse le plateau 43 par l'ouverture centrale de celui-ci. On met en place le sous-ensemble ainsi obtenu sur le récipient en introduisant le pot de valve 32 dans le récipient par l'ouverture 22, jusqu'à ce que le joint 7 soit en appui sur le bourrelet de fixation 23. Par action d'un effort exercé sur la coupelle 4 selon l'axe du récipient, on provoque alors l'encliquetage du jonc 45 sous le bourrelet 23. On visse alors la bague 5 sur la jupe extérieure 42 de la coupelle 4 ; à la fin du vissage, les dents de blocage 56 de la bague 5 et les dents de blocage 46 de la coupelle 4 coopèrent entre elles et immobilisent la bague en position vissée. La valve 3 est alors bloquée de façon étanche sur le dôme 2 du récipient 1.To mount this fixing device, the seal 6 is placed in the housing 34 formed on the flange 33 of the valve pot 32 and the seal 7 around the valve pot but below the flange 33. The cup 4 around the valve 2 by fitting the collar 33 of the valve body 32 between the plate 43 and the upper bead 44 of the inner skirt 41 of the cup 4. The outlet tube 31 passes through the plate 43 through the central opening of it. The subassembly thus obtained is put in place on the container by introducing the valve pot 32 into the container through the opening 22, until the seal 7 is in abutment on the fixing bead 23. By action of 'a force exerted on the cup 4 along the axis of the container, then causes the snap ring 45 under the bead 23. Then screwing the ring 5 on the outer skirt 42 of the cup 4; at the end of the screwing, the locking teeth 56 of the ring 5 and the teeth of locking 46 of the cup 4 cooperate with each other and immobilize the ring in the screwed position. The valve 3 is then tightly blocked on the dome 2 of the container 1.
