Abstract

The removable valve consists of a split ring (5) each half of which fits under the hollow rim at the top of the aerosol can (1). The two half-rings are held in place by an outer nut (8). The valve (11) is screwed into the split ring (5). The central passage of the valve is extended in the form of a chisel-edged tube (12). When the valve is screwed down, the tube (12) punches the membrane (3) of the aerosol. A sealing ring (14) ensures a gas tight installation.

Description

On utilise de plus en plus des aérosols, c'est-àdire des produits comprenant un gaz liquéfié ou un liquide sous haute pression formant véhicule auquel est mélangé un ou des produits actifs soit pour traiter des plantations, soit pour être ajoutés à des liquides, soit pour entretenir une atmosphère particulière, mais en général les produits dénommés aérosols", qui sont contenus dans des récipients le plus souvent cylindriques appelés "bombes", peuvent être libérés en utilisant une valve placée au sommet de la bombe.La valve est ouverte par pression, soit d'un doigt de l'utilisateur, soit d'un dispositif approprié, mais ces bombes à valves n'ont pas toujours donné satisfaction car le contenu gaz liquéfié, liquide sous pression, auquel est ajouté le ou les produits de traitement est très souvent corrosif, et, en conséquence, au cours du stockage, détériore considérablement la valve, ce qui fait que la bombe fuit ou se trouve bouchée et rend impossible son utilisation. More and more aerosols are used, that is to say products comprising a liquefied gas or a liquid under high pressure forming a vehicle with which one or more active products is mixed either for treating plantations or for being added to liquids, either to maintain a particular atmosphere, but in general the products called aerosols ", which are contained in receptacles most often cylindrical called" bombs ", can be released by using a valve placed at the top of the bomb. The valve is opened by pressure, either from a finger of the user, or from an appropriate device, but these valve bombs have not always been satisfactory because the content of liquefied gas, liquid under pressure, to which is added the treatment product (s) is very often corrosive, and, consequently, during storage, considerably deteriorates the valve, which means that the bomb leaks or becomes blocked and makes its use impossible.

la présente invention remédie à cet inconvénient en utilisant, comme récipients contenant des aérosols, des bombes fermées normalement par un opercule le plus souvent métallique et qui peut être choisi dans une matière résistant aux agents considérés, opercule qui est perforé au moment de l'emploi de la bombe par un organe approprié placé au moment de l'utilisation sur la bombe et qui, de ce fait, est d'abord très largement dimensionné et peut résister à l'attaque des produits corrosifs et ne subir d'autre part cette attaque que pendant la période d'utilisation de la bombe qui est, en général, assez courte, au maximum de quelques jours ou tout au plus de quelques semaines. the present invention overcomes this drawback by using, as containers containing aerosols, bombs normally closed by a cover which is generally metallic and which can be chosen from a material resistant to the agents in question, a cover which is perforated at the time of use of the bomb by an appropriate member placed at the time of use on the bomb and which, therefore, is first of all very broadly dimensioned and can withstand the attack of corrosive products and on the other hand not undergo this attack only during the period of use of the bomb, which is generally quite short, at most a few days or at most a few weeks.

Conformément à l'invention, l'obturateur constitué par un corps de vanne contenant une soupape mobile dés la çable par un organe mécanique est fixé par vissage dans le taraudage intérieur d'une couronne constituée par deux demi-coquilles présentant un pourtour fileté extérieur destiné à recevoir un écrou de maintien et qui sont munies d'une zone arrondie rentrante se terminant par un saillant destiné à pénétrer dans le bord interne de la collerette circulaire afin d'assurer l'homogénéité entre le récipient et le corps de vanne. In accordance with the invention, the shutter constituted by a valve body containing a movable valve as soon as it can be connected by a mechanical member is fixed by screwing into the internal thread of a crown constituted by two half-shells having an external threaded periphery intended to receive a retaining nut and which are provided with a re-entrant rounded zone ending in a projection intended to penetrate into the internal edge of the circular flange in order to ensure homogeneity between the container and the valve body.

Suivant une autre particularité de l'invention, un pont déformable souple est placé sous le corps de vanne dans la collerette du récipient afin d'assurer l'étanchéité entre le récipient et le corps de vanne. According to another feature of the invention, a flexible deformable bridge is placed under the valve body in the flange of the container in order to ensure sealing between the container and the valve body.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention est représentée, à titre d'exemple, au dessin annexé. An embodiment of the object of the invention is shown, by way of example, in the accompanying drawing.

La fig. 1 est une coupe-élévation de la partie de support de l'obturateur. Fig. 1 is a sectional elevation of the support part of the shutter.

La fig. 2 est un plan correspondant à la fig. 1. Fig. 2 is a plane corresponding to FIG. 1.

la fig. 5 montre l'obturateur en cours de montage sur la partie supérieure d'une bombe fermée par un opercule. fig. 5 shows the shutter being mounted on the upper part of a bomb closed by a cover.

La fig. 4 montre l'obturateur monté avant la perforation de l'opercule. Fig. 4 shows the shutter mounted before the perforation of the cover.

la fig. 5 montre l'obturateur en fonctionnement sur la bombe. fig. 5 shows the shutter in operation on the bomb.

Comme on peut s'en rendre compte au dessin, la bombe 1, qui est un récipient cylindrotronconique contenant l'aérosol, c'est-à-dire un gaz comprimé, un liquide sous pression, etc., auquel peut être ajouté un ou des produits actifs, est normalement fermée, à sa partie supérieure, par un conduit 2 obturé par un opercule 3. Ce conduit 2 est entouré par une collerette 4 sur laquelle peut être montée une couronne 5 composée de deux demicoquilles Sa, 5b présentant, à leur partie inférieure, une zone arrondie 6 terminée par un saillant coupant 7 qui vient se placer sous la collerette 4. Lorsque la couronne 5 est ainsi constituée, on la maintient en place par un écrou 8 à six pans qui se visse sur la partie filetée extérieure 9 de la couronne 5.Lorsque l'écrou 8 est en place et que le saillant 7 est bien serré sous la col- lerette 4, cet ensemble est très homogène et peut recevoir, du fait du taraudage intérieur 10, le corps d'une vanne 11 (voir fig 4) dont le dispositif permettant l'écnappement vers l'extérieur de l'aérosol, en général une soupape, est commandé par exemple par un volant, non représenté. Le corps de vanne Il porte à sa partie inférieure un conduit central 12 qui se termine par un biseau coupant 13. Ce dernier peut perforer l'opercule 3 lors de la mise en place du corps de vanne Il sur la couronne 5 et ainsi mettre en communication l'intérieur de la bombe 1 avec l'intérieur du corps de vanne Il et lorsque la
y soupape est ouverte, l'aérosol peut s'échapper vers l'extérieur.Ainsi, et comme le montre la fig. 5, on peut aisément utiliser l'aérosol contenu dans la bombe 1 sans qu'il y ait détérioration du dispositif de fermeture de cette bombe 1 même si l'aérosol est de nature corrosive.As can be seen in the drawing, the bomb 1, which is a cylindrical-conical container containing the aerosol, that is to say a compressed gas, a pressurized liquid, etc., to which can be added one or active products, is normally closed, at its upper part, by a conduit 2 closed by a cover 3. This conduit 2 is surrounded by a collar 4 on which can be mounted a crown 5 composed of two half-shells Sa, 5b having, at their lower part, a rounded zone 6 terminated by a cutting projection 7 which is placed under the flange 4. When the crown 5 is thus formed, it is held in place by a hexagonal nut 8 which is screwed onto the threaded part outer 9 of the crown 5.When the nut 8 is in place and the protrusion 7 is well tightened under the collar 4, this assembly is very homogeneous and can receive, due to the internal thread 10, the body of a valve 11 (see fig 4), the device for which the entrapment t towards the outside of the aerosol, in general a valve, is controlled for example by a flywheel, not shown. The valve body It carries at its lower part a central conduit 12 which ends in a cutting bevel 13. The latter can perforate the cover 3 during the positioning of the valve body Il on the crown 5 and thus put in communication inside the bomb 1 with the inside of the valve body II and when the
If the valve is open, the aerosol can escape to the outside, and as shown in fig. 5, the aerosol contained in the canister 1 can easily be used without deterioration of the closure device of this canister 1 even if the aerosol is of a corrosive nature.

Un autre mode de réalisation de la perforation peut être réalisé de la manière suivante. Another embodiment of the perforation can be carried out as follows.

On fixe un embout pointu qui descend jusqu'8 la base de la queue de la vanne lorsque la vanne est en position ouverte. A pointed tip is fixed which descends to the base of the valve stem when the valve is in the open position.

Dans ce cas, lorsque l'on visse la vanne (en position ouverte) dans le filetage intérieur du cylindre, la base de la vanne vient en application contre le joint cylindrique et l'on visse la vanne Jusqutà comprimer ce joint pour assurer l'étanchéité. Puis, on ferme cette vanne rapidement ce qui entraîne la descente du piston et aussi la descente de l'embout pointu dépendant de ce piston qui vient ainsi perforer la coupelle de l'aérosol en même temps que la vanne est ainsi opérationnelle. In this case, when the valve is screwed (in the open position) into the internal thread of the cylinder, the base of the valve comes into application against the cylindrical seal and the valve is screwed Until compressing this seal to ensure the sealing. Then, this valve is closed quickly, which brings down the piston and also the descent of the pointed tip depending on this piston which thus punctures the aerosol cup at the same time as the valve is thus operational.

Ces deux exemples précédents sont donnés à titre indicatif, mais non limitatif, des variantes étant évidemment nombreuses. These two previous examples are given as an indication, but not limitative, variations are obviously numerous.

Afin d'assurer une étanchéité parfaite entre la couronne 5, la vanne Il et la partie supérieure de la bombe 1, on place un joint d'échantéité 14 à l'intérieur de la collerette 4 (voir fig. 5) ; ce joint qui est déformé, aplati, lors du montage du corps de vanne 11, est réalisé le plus souvent en une matière plastique souple résistant aux agents considérés. In order to ensure a perfect seal between the crown 5, the valve II and the upper part of the bomb 1, a sample seal 14 is placed inside the collar 4 (see fig. 5); this seal which is deformed, flattened, during assembly of the valve body 11, is most often made of a flexible plastic material resistant to the agents considered.

Bien entendu certaines variantes de construction peuvent faciliter, suivant la forme des collerettes 4 placées à la partie supérieure de la bombe 1, la mise en place du support de la vanne Il ; par exemple, à la place de l'écrou à six pans 8, on pourrait avoir un écrou à surface extérieure moletée pour un serrage manuel facile. Of course, certain construction variants can facilitate, depending on the shape of the flanges 4 placed at the top of the bomb 1, the positioning of the valve support II; for example, instead of the hexagon nut 8, there could be a nut with knurled outer surface for easy manual tightening.

En général, l'ensemble des pièces qui vient d'être décrit est réalisé en un matériau résistant aux agents #tnsidérés, qui sont souvent très caustiques, et on emploie, par exemple, le laiton. In general, all of the parts which have just been described are made of a material resistant to the agents considered, which are often very caustic, and brass, for example, is used.

Si la bombe 1 contient un gaz liquéfié, le corps de vanne Il n'ayant pas de tube plongeur entrant dans la bombe 1, il est nécessaire pour se servir de l'appareil de le renverser la tête en bas afin d'éviter des phénomènes de formation de glace par condensation de l'humidité se givrant au passage d'un gaz liquéfié se détendant. En effet, dans le cas contraire, si la bombe était maintenue dans la position tête en haut, il y aurait rapidement obstruction du conduit contrôlé par la vanne du fait de la condensation etformationde glace par cçndensation de lthumidité ambiante. If the bomb 1 contains a liquefied gas, the valve body It having no dip tube entering the bomb 1, it is necessary to use the device to overturn it upside down in order to avoid phenomena of ice formation by condensation of the frosting humidity with the passage of a relaxing liquefied gas. Otherwise, if the bomb was kept in the head-up position, the duct controlled by the valve would quickly obstruct due to condensation and ice formation by condensation of the ambient humidity.

Un emploi très intéressant se situe dans l'industrie vinicole, car on peut utiliser, avec cet obturateurs des aérosols contenant de l'anhydride sulfureux, ce gaz ayant toujours provoqué des problèmes au niveau des valves par corrosion des parties métalliques et sulfatage de ces mêmes parties. Comme l'ensemble des pièces constituant cet obturateur mobile peut être démonté facilement puis nettoyé si nécessaire, on peut se servir de multiples fois de cet appareil avec une grande sécurité. A very interesting job is in the wine industry, because one can use, with this shutter aerosols containing sulfur dioxide, this gas having always caused problems at the level of the valves by corrosion of the metallic parts and sulfation of these same parts. As all of the parts making up this mobile shutter can be easily disassembled and then cleaned if necessary, this device can be used multiple times with great safety.

l'invention n'est pas limitée à l'exemple de réalisation représenté et décrit en détail car diverses modifications peuvent y être apportées sans sortir de son cadre.  the invention is not limited to the embodiment shown and described in detail since various modifications can be made without departing from its scope.
