Description

La présente invention concerne les valves de vaporisateur du type qui sont montées dans l'ouverture d'un récipient, tel qu'un flacon ou un bidon aérosol pour en extraire le contenu et le projeter en l'atomisant; le mot "valve" comprenant ici tout aussi bien les systèmes de pompe actionnées à la main que les systèmes utilisant un gaz propulseur logé dans le récipient, soluble ou non dans le liquide à pulvériser. L'invention a pour objet un dispositif permettant le fonctionnement dans toutes les positions d'une valve prévue pour fonctionner dans une seule position déterminée (position droite), c'est-à-dire l'emploi du vaporisateur aussi bien en position droite qu'en position inversée. Selon une caractéristique avantageuse de l'invention, le dispositif est particulièrement adapté aux valves prévues pour être montées sur des récipients à ouverture étroite. Le dispositif de l'invention convient particulièrement aux systèmes comportant une pompe, actionnée par le doigt de l'utilisateur.The present invention relates to vaporizer valves of the type which are mounted in the opening of a container, such as a bottle or an aerosol can to extract the content and spray it while atomizing it; the word "valve" here comprising both hand-operated pump systems and systems using a propellant gas housed in the container, soluble or not in the liquid to be sprayed. The invention relates to a device allowing the operation in all positions of a valve intended to operate in a single determined position (straight position), that is to say the use of the vaporizer both in the straight position as 'in reverse position. According to an advantageous characteristic of the invention, the device is particularly suitable for valves intended to be mounted on containers with a narrow opening. The device of the invention is particularly suitable for systems comprising a pump, actuated by the user's finger.

On connait déjà, dans le brevet japonais 55-157 352, un dispositif permettant le fonctionnement (aussi bien en position inversée qu'en position droite) d'une valve aérosol destinée à être sertie dans le col d'un bidon, ledit dispositif étant prévu pour être interposé entre l'embout d'entrée de la valve et un tube plongeur, ce dispositif comprenant deux chambres en série alignées sur l'axe de la valve, séparées par un canal ayant une embouchure dans chaque chambre, ledit canal étant en communication avec la zone d'aspiration de la valve, chaque chambre comportant un clapet commandé par gravité sur l'embouchure dudit canal, le clapet étant fermé quand l'embouchure est placée vers le bas, la chambre la plus proche de la valve étant par ailleurs en communication par son extrémité opposée à l'embouchure du canal avec une zone extérieure à la valve et proche de la valve et la chambre la plus éloignée de la valve étant par ailleurs en communication par son extrémité opposée à l'embouchure du canal avec ledit tube plongeur. Un tel dispositif a des applications intéressantes, mais est difficile à fabriquer et à assembler.Already known, in Japanese patent 55-157352, a device allowing the operation (both in inverted position and in upright position) of an aerosol valve intended to be crimped in the neck of a container, said device being designed to be interposed between the inlet end of the valve and a dip tube, this device comprising two chambers in series aligned on the axis of the valve, separated by a channel having a mouth in each chamber, said channel being in communication with the suction zone of the valve, each chamber comprising a valve controlled by gravity on the mouth of said channel, the valve being closed when the mouth is placed downwards, the chamber closest to the valve being elsewhere in communication by its end opposite the mouth of the canal with an area external to the valve and close to the valve and the chamber furthest from the valve being moreover in communication by its extr emitted opposite to the mouth of the channel with said dip tube. Such a device has interesting applications, but is difficult to manufacture and assemble.

La présente invention a pour objet une structure avantageuse simplifiée pour la fabrication d'un tel dispositif.The present invention relates to a simplified advantageous structure for the manufacture of such a device.

Selon l'invention, le dispositif comporte trois pièces de forme générale tubulaire montées concentriquement, un manchon extérieur pouvant recevoir le corps de la valve, une pièce tubulaire pouvant s'engager sur l'embout d'entrée de la valve et une douille définissant les chambres avec ladite pièce tubulaire et comportant ledit canal. Selon une autre caractéristique avantageuse de l'invention, la douille comporte une partie moulée à une largeur supérieure à sa largeur montée dans le dispositif, cette partie étant resserrée lors de l'assemblage du dispositif, par introduction dans la pièce tubulaire, le resserement provoquant la fermeture d'une chambre. Cette disposition permet d'introduire une bille dans la chambre, avant de refermer cette chambre par introduction complète à sa place de la douille dans la pièce tubulaire.According to the invention, the device comprises three parts of generally tubular shape mounted concentrically, an outer sleeve which can receive the body of the valve, a tubular part which can engage on the inlet end of the valve and a socket defining the chambers with said tubular part and comprising said channel. According to another advantageous characteristic of the invention, the sleeve comprises a part molded to a width greater than its width mounted in the device, this part being tightened during assembly of the device, by introduction into the tubular part, the tightening causing closing a room. This arrangement makes it possible to introduce a ball into the chamber, before closing this chamber by completely inserting the sleeve into the tubular part in its place.

D'autres caractéristiques et avantages apparaîtront au cours de la description suivante, donnée à titre d'exemples non limitatifs et qui fera mieux comprendre comment l'invention peut être réalisée, faite en relation avec les dessins annexés, sur lesquels:

  • la figure 1 est une vue en coupe d'un dispositif selon l'invention adapté sur une valve ordinaire, prévue pour fonctionner seulement en position droite;
  • la figure 2 est une vue en coupe, suivant la ligne II-II de la figure 1;
  • la figure 3 est une vue agrandie d'un détail d'une pièce du dispositif de la figure 1, avant assemblage avec les autres pièces du dispositif; et,
  • la figure 4 est une vue en coupe suivant la ligne IV-IV de la figure 1.
Other characteristics and advantages will appear during the following description, given by way of nonlimiting examples and which will make it easier to understand how the invention can be produced, made in relation to the appended drawings, in which:
  • Figure 1 is a sectional view of a device according to the invention adapted on an ordinary valve, intended to operate only in an upright position;
  • Figure 2 is a sectional view along line II-II of Figure 1;
  • Figure 3 is an enlarged view of a detail of a part of the device of Figure 1, before assembly with the other parts of the device; and,
  • Figure 4 is a sectional view along line IV-IV of Figure 1.

Dans l'exemple représenté, le dispositif est adapté sur une valve 1 au moyen d'un manchon 2. La valve est destinée à être montée de façon classique dans le col d'un récipient, non représenté, au moyen d'une capsule sertie sur le rebord 1a de la valve. La valve peut être de tout type: pompe, soupape, doseuse ou non. Il s'agit dans cet exemple d'une valve de forme générale tubulaire, de petit diamètre, permettant sa mise en place dans le goulot, ou col de flacons ou bidons étroits. L'invention s'applique à tous les types de valves, étroites ou non, mais elle trouve une application particulièrement intéressante dans le cas des valves étroites.In the example shown, the device is adapted to a valve 1 by means of a sleeve 2. The valve is intended to be mounted in a conventional manner in the neck of a container, not shown, by means of a crimped capsule. on the edge 1a of the valve. The valve can be of any type: pump, valve, metering or not. In this example, it is a valve of generally tubular shape, of small diameter, allowing it to be placed in the neck, or neck of bottles or narrow cans. The invention applies to all types of valves, narrow or not, but it finds a particularly advantageous application in the case of narrow valves.

A l'intérieur du manchon 2, dans le prolongement axial de la valve 1, sont disposées deux chambres 11, 12 en série connectées entre elles par un canal 13. Chaque chambre comporte une autre ouverture, opposée à l'embouchure du canal, l'ouverture 14 pour la chambre 11 et l'ouverture 15 pour la chambre 12. Dans chaque chambre est logée une petite bille, respectivement 11a et 12a assurant une fonction de clapet avec l'embouchure correspondante 11b, 12b du canal, ces embouchures formant des sièges de clapet. Par petite bille, on entend ici une bille d'un diamètre sensiblement inférieur à 4 mm, par exemple de l'ordre de 2 mm ou moins. En général, dans les valves, jusqu'à maintenant, on utilise pour réaliser des clapets, des billes de diamètre supérieur ou égal à 4 mm, sans quoi, les billes risquent d'être entraînées par le courant de fluide, avant d'être plaquées sur leurs sièges. Cette possibilité d'utiliser des petites billes est offerte par la forme des chambres conformément à la présente invention, comme cela est expliqué ci-après. Au milieu du canal 13 est formé un orifice 16 communiquant avec l'entrée 17 (ou zone d'aspiration) de la valve 1.Inside the sleeve 2, in the axial extension of the valve 1, are arranged two chambers 11, 12 in series connected to each other by a channel 13. Each chamber has another opening, opposite the mouth of the channel, l opening 14 for chamber 11 and opening 15 for chamber 12. In each chamber is housed a small ball, respectively 11a and 12a providing a valve function with the corresponding mouth 11b, 12b of the channel, these mouths forming valve seats. By small ball is meant here a ball with a diameter substantially less than 4 mm, for example of the order of 2 mm or less. In general, in the valves, until now, one uses to make valves, balls of diameter greater than or equal to 4 mm, without which, the balls risk being entrained by the current of fluid, before being plated on their seats. This possibility of using small balls is offered by the shape of the chambers in accordance with the present invention, as explained below. In the middle of the channel 13 is formed an orifice 16 communicating with the inlet 17 (or suction zone) of the valve 1.

L'ouverture 14 de la chambre 11, la plus proche de la valve, est en communication avec la zone intérieure 18 du récipient proche du goulot (en haut, quand le récipient est en position debout de non utilisation) et l'ouverture 15 est en communication avec le tube plongeur 3.The opening 14 of the chamber 11, the closest to the valve, is in communication with the interior zone 18 of the container close to the neck (at the top, when the container is in the standing position when not in use) and the opening 15 is in communication with the dip tube 3.

Fonctionnement: quand la valve est debout, la bille 12a repose au fond de la chambre, et l'embouchure 12b est dégagée, tandis que la bille 11a repose sur le siège 11b. L'embouchure 11b est fermée. Dans cette position, l'intérieur du tube plongeur 3 est en communication avec la zone d'entrée 17 de la valve 1. Si l'on fait fonctionner la valve, le produit contenu dans le bidon pourra passer par le tube plongeur et monter, par pression ou par aspiration jusqu'à l'ouverture 15 dans la chambre 12, et de là, par le canal 13 et l'orifice 16, jusqu'à la zone d'aspiration de la valve 1, qui fonctionnera normalement sans pouvoir plaquer la bille 12a sur le siège 12b malgré son petit diamètre, grâce à la disposition des passages. La région 18, voisine dans cette position de la partie supérieure du bidon, est alors en atmosphère gazeuse. Cette région communique avec la chambre 11, mais celle-ci est fermée vers le bas par le clapet formé par la bille 11a reposant sur le siège 11b. Si l'intérieur du bidon est sous pression, grâce à un fluide propulseur, cette pression s'applique sur le clapet 11a, et maintient celui-ci fermé. Si l'intérieur du bidon n'est pas sous pression, c'est l'aspiration de la valve qui maintient le clapet fermé.Operation: when the valve is standing, the ball 12a rests at the bottom of the chamber, and the mouth 12b is released, while the ball 11a rests on the seat 11b. The mouth 11b is closed. In this position, the inside of the dip tube 3 is in communication with the inlet zone 17 of the valve 1. If the valve is operated, the product contained in the container can pass through the dip tube and go up, by pressure or by suction to the opening 15 in the chamber 12, and from there, through the channel 13 and the orifice 16, to the suction zone of the valve 1, which will operate normally without being able to press the ball 12a on the seat 12b despite its small diameter, thanks to the arrangement of the passages. Region 18, adjacent in this position to the upper part of the container, is then in a gaseous atmosphere. This region communicates with the chamber 11, but the latter is closed downwards by the valve formed by the ball 11a resting on the seat 11b. If the interior of the container is under pressure, thanks to a propellant fluid, this pressure is applied to the valve 11a, and keeps it closed. If the inside of the container is not under pressure, it is the suction of the valve which keeps the valve closed.

Si l'on fait fonctionner le dispositif en position inversée, c'est alors la région 18 qui est immergée dans le produit à expulser par la valve, tandis que l'extrémité du tube plongeur est en atmosphère gazeuse. La valve étant retournée, c'est le clapet 12a, 12b qui est fermé tandis que le clapet 11a, 11b est ouvert, et ainsi le dispositif fonctionne encore de la façon désirée.If the device is operated in the inverted position, it is then the region 18 which is immersed in the product to be expelled by the valve, while the end of the dip tube is in a gaseous atmosphere. The valve being returned, it is the valve 12a, 12b which is closed while the valve 11a, 11b is open, and thus the device still functions as desired.

Le dispositif est remarquable notamment par ses dimensions réduites, l'ensemble se trouvant dans le prolongement de la valve et étant logé dans le manchon 2 qui a pratiquement les dimensions de la valve qui peut être très mince. Ceci rend nécessaire l'emploi de billes de petit diamètre. Elles risquent d'être entraînées par le courant de fluide, et d'être plaquées sur le siège, ce qui interrompt la pulvérisation. Pour éviter cet inconvénient, l'invention a prévu de placer les billes de telle sorte qu'elles ne soient pas dans le courant du fluide en déplacement. Pour ce faire, chaque chambre 11, 12 est formée avec une cuvette 11c, 12c opposée à l'entrée du canal 13. Dans ces conditions, sous l'effet de la pesanteur, une des billes ferme un clapet et l'autre bille repose dans le fond de sa cuvette, à l'écart du courant de fluide qui risquerait de la soulever et la plaquer sur le siège.The device is remarkable in particular by its reduced dimensions, the assembly being in the extension of the valve and being housed in the sleeve 2 which has practically the dimensions of the valve which can be very thin. This makes it necessary to use small diameter balls. They risk being entrained by the flow of fluid, and being pressed against the seat, which interrupts spraying. To avoid this drawback, the invention provides for placing the balls so that they are not in the flow of the moving fluid. To do this, each chamber 11, 12 is formed with a bowl 11c, 12c opposite the entrance to the channel 13. Under these conditions, under the effect of gravity, one of the balls closes a valve and the other ball rests in the bottom of its bowl, away from the flow of fluid which could lift it and press it against the seat.

L'invention a pour objet des moyens pour permettre la réalisation industrielle dans des conditions économiquement favorables.The invention relates to means for enabling industrial production under economically favorable conditions.

Le dispositif selon invention est constitué, en dehors de la valve 1 et du tube plongeur 3, des deux billes et de trois pièces moulées en matière plastique. Une première pièce est constituée par le manchon 2, dans lequel on vient engager la valve. A la hauteur du manchon qui correspond à la base de la valve, est prévue une chambre circulaire 21, de laquelle part au moins une saignée interne 22 s'étendant jusqu'au bout du manchon pour assurer la communication avec l'espace 18 intérieur du bidon, mais extérieur à la valve. Sur la coupe de la figure 2, on a prévu deux telles saignées 22, 22′.The device according to the invention consists, apart from the valve 1 and the dip tube 3, of the two balls and of three molded plastic parts. A first part is formed by the sleeve 2, in which the valve is engaged. At the height of the sleeve which corresponds to the base of the valve, a circular chamber 21 is provided, from which at least one internal groove 22 extends to the end of the sleeve to ensure communication with the interior space 18 of the can, but outside the valve. In the section of FIG. 2, two such grooves 22, 22 ′ are provided.

Une pièce tubulaire 4 est logée à l'intérieur du manchon 2, et est enfilée sur l'embout 1a de la valve 1, en lieu et place d'un tube plongeur extérieur. Cette pièce comporte une cloison transversale 41, séparant un volume comportant la valve d'un volume comportant les chambres à clapet. La cloison 41 est située à une distance de l'extrémité de ladite pièce tubulaire 4, légèrement supérieure à la longueur de l'embout 1a de la valve 1. La cloison 41 définit avec l'extrémité de l'embout de la valve la zone d'entrée ou d'aspiration 17 de la valve 1. La pièce tubulaire 4 est formée, au niveau de cette zone, avec une ouverture 42 faisant communiquer l'intérieur de la pièce, c'est-à-dire la zone 17, avec l'extérieur où est formée une saignée longitudinale 43 s'étendant jusqu'à une autre ouverture 44 au niveau de l'orifice 16 débouchant dans le canal 13 entre les deux chambres. La pièce tubulaire 4 comporte encore une saignée longitudinale 45 s'étendant depuis l'extrémité supérieure de la pièce, jusqu'au niveau de la chambre 11 avec laquelle elle communique par une ouverture 14. Ainsi est réalisée la communication entre la chambre 11 et la zone 18 extérieure à la valve, par l'ouverture 14, la saignée 45, la chambre annulaire 21 formée dans le manchon 2, et les saignées 22, 22′. Bien entendu, il n'est pas nécessaire que la saignée 45 soit dans le même plan qu'une saignée 22. Grâce à la chambre annulaire 21, les orientations des pièces 2 et 4 sont indifférentes.A tubular part 4 is housed inside the sleeve 2, and is threaded onto the end piece 1a of the valve 1, in place of an external dip tube. This part comprises a transverse partition 41, separating a volume comprising the valve from a volume comprising the valve chambers. The partition 41 is located at a distance from the end of said tubular part 4, slightly greater than the length of the end piece 1a of the valve 1. The partition 41 defines with the end of the end piece of the valve the zone inlet or suction 17 of the valve 1. The tubular part 4 is formed, at this zone, with an opening 42 communicating the interior of the part, that is to say zone 17, with the outside where a longitudinal groove 43 is formed extending to another opening 44 at the orifice 16 opening into the channel 13 between the two chambers. The tubular part 4 also comprises a longitudinal groove 45 extending from the upper end of the part, up to the level of the chamber 11 with which it communicates by an opening 14. Thus communication between the chamber 11 and the zone 18 external to the valve, through the opening 14, the groove 45, the annular chamber 21 formed in the sleeve 2, and the grooves 22, 22 ′. Of course, it is not necessary for the groove 45 to be in the same plane as a groove 22. Thanks to the annular chamber 21, the orientations of the parts 2 and 4 are indifferent.

Une douille 5 complète le dispositif. Elle comporte une partie principale définissant le canal 13 et les deux sièges de clapet 11b et 12b. Le siège de clapet 11b et la cloison 41 de la pièce tubulaire définissent la chambre 11. Le siège de clapet 12b et une partie secondaire 51 de la douille 5 définissent la chambre 12. La partie principale est formée avec une saignée circulaire 49 dans laquelle débouche l'orifice 16, ainsi que l'ouverture 44. Grâce à cette saignée circulaire, les orientations relatives de la douille 5 et de la pièce tubulaire 4 sont indifférentes. Il n'est pas nécessaire que la saignée 43, avec l'ouverture 44 soit dans le même plan que l'orifice 16. Ceci n'a été représenté ainsi que pour la commodité de compréhension du dessin.A socket 5 completes the device. It comprises a main part defining the channel 13 and the two valve seats 11b and 12b. The valve seat 11b and the partition 41 of the tubular part define the chamber 11. The valve seat 12b and a secondary part 51 of the socket 5 define the chamber 12. The main part is formed with a circular groove 49 into which opens out the orifice 16, as well as the opening 44. Thanks to this circular groove, the relative orientations of the sleeve 5 and of the tubular part 4 are indifferent. The groove 43, with the opening 44, need not be in the same plane as the orifice 16. This has been shown only for the convenience of understanding the drawing.

La partie secondaire 51 de la douille comporte une cuvette 12c rattachée à la partie principale par au moins un bras 52. De préférence, la cuvette est constituée de plusieurs morceaux 53, 53′, au moins deux, avantageusement trois ou quatre, constitués ― et s'assemblant entre eux à la manière ― de quartiers, chacun étant tenu par un bras 52, 52′. Cette partie de la douille 5 est moulée sous la forme représentée à la figure 3. C'est en introduisant la douille dans le tube 4 que les bras 52 se rapprochent et les quartiers 53, 53′ se serrent les uns contre les autres pour former la cuvette 51 tout en laissant la chambre 12 communiquer avec le tube plongeur 3 par les espaces laissés entre les bras 52, 52′. Il suffit, lors du montage, d'introduire la bille 12a au bon moment, avant la fermeture de la cuvette 51. Les extrémités des bras 52, 52′ s'étendant au-delà des quartiers 53, 53′ servent de butée au tube plongeur 3 pour permettre le passage du fluide autour de la cuvette 51. Le moulage de la cuvette en une seule pièce, solidaire d'un seul bras 52 est possible, mais cette disposition paraît ne pas favoriser les opérations d'assemblage et de montage du dispositif.The secondary part 51 of the sleeve comprises a bowl 12c attached to the main part by at least one arm 52. Preferably, the bowl consists of several pieces 53, 53 ′, at least two, advantageously three or four, made up of - and joining together in the manner of - quarters, each held by an arm 52, 52 ′. This part of the socket 5 is molded in the form shown in FIG. 3. It is by introducing the socket into the tube 4 that the arms 52 come together and the quarters 53, 53 ′ are pressed against each other to form the bowl 51 while letting the chamber 12 communicate with the dip tube 3 through the spaces left between the arms 52, 52 ′. It suffices, during assembly, to introduce the ball 12a at the right time, before the closure of the bowl 51. The ends of the arms 52, 52 ′ extending beyond the quarters 53, 53 ′ serve as a stop for the tube plunger 3 to allow the passage of the fluid around the bowl 51. The molding of the bowl in one piece, secured to a single arm 52 is possible, but this arrangement does not seem to favor the assembly and mounting operations of the device.

La figure 4 montre clairement les trois parties de la cuvette 51 avec pour chacune le bras 52 correspondant. Les bras laissent entre eux les passages 15, entourés par la pièce tubulaire 4.Figure 4 clearly shows the three parts of the bowl 51 with each corresponding arm 52. The arms leave between them the passages 15, surrounded by the tubular part 4.

Claims (4)

1. A device for enabling an aerosol valve designed to be crimped in the neck of a can to operate both upsidedown and the rightway up, said device being designed to be placed between the inlet end fitting of the valve and a dip tube, and comprising two chambers (11, 12) in series and aligned on the axis of the valve, said chambers being interconnected by a channel (13) having an opening into each of said chambers, said channel (13) also being in communication with the suction zone (17) of the valve, each chamber including a gravity-operated non-return valve member for engaging the opening of said channel, the non-return valve member occupying a closed position when the channel opening is in the bottom of the chamber, the chamber which is closer to the valve (1) also being in communication with a zone (18) outside the valve and close to the valve via the end of the chamber which is opposite to its channel opening, and the chamber (12) which is further from the valve (1) also being in communication with said dip tube (3) via its end which is opposite to its channel opening, characterized in that said device comprises three generally tubular parts mounted concentrically, namely: an outer sleeve (2) suitable for receiving the valve body; a tubular part (4) for engaging on the inlet end fitting of the valve; and a central bush (5) including said channel (13) and defining said chambers in conjunction with said tubular part.
2. A device according to claim 1, characterized in that the bush (5) includes a portion (51) which is molded to be wider than the width it occupies when mounted in the device, with said portion being urged together during assembly of the device by the bush being inserted into the tubular part (4), with said urging causing one (12) of the chambers to be closed.
3. A device according to anyone of the preceding claims, characterized in that the non-return valve members are constituted by balls of small diameter, about 2 mm or less.
