Abstract

Le dispositif comporte une douille 1 dans laquelle peut tourner et coulisser un bouton poussoir (2) emmanché sur la tige de soupape (28) d'une valve (25) montée dans l'ouverture d'un bidon (26) au moyen d'une capsule (22). Le bord interne de la capsule est serti sur la valve et le bord externe est serti sur l'ouverture du bidon. La douille comporte une collerette interne (3) encloquetée sur le sertissage interne de la capsule sur la valve. La dimension de la douille est ainsi indépendante de la dimension et de la forme du bidon. Avec un sertissage polygonal (22c) de la capsule sur la valve, on peut obtenir un blocage en rotation de la douille. On ne risque pas de faire tourner la douille avec le bouton, quand on fait tourner celui- ci, pour le mettre hors de la position de sécurité.

The device comprises a socket 1 in which a push button (2) fitted on the valve stem (28) of a valve (25) mounted in the opening of a container (26) can rotate and slide. a capsule (22). The inner edge of the capsule is crimped on the valve and the outer edge is crimped on the opening of the container. The sleeve has an internal collar (3) fitted onto the internal crimping of the capsule on the valve. The size of the sleeve is thus independent of the size and shape of the container. With a polygonal crimp (22c) of the capsule on the valve, it is possible to obtain a blocking in rotation of the sleeve. There is no risk of turning the socket with the button, when it is rotated, to put it out of the safety position.

Description

La présente invention a pour objet un dispositif d'actionnement de sécurité pour v lve aérosol. Un tel dispositif de sécurité est utilisable par exemple pour les bombes aérosols prévues pour être placées dans une poche, un sac ou une valise, par exemple un vaporisateur de parfum pour le voyage, ot un vaporisateur de gaz pour la défense. Dans ce genre d'utilisation, on recherche à éviter un fonctionnement intempestif qui peut être très préjudiciable aux objets voisins, aux vêtements et sacs mêmes.The present invention relates to a safety actuating device for aerosol v lve. Such a safety device can be used, for example, for aerosol cans intended to be placed in a pocket, bag or suitcase, for example a perfume vaporizer for travel, or a gas vaporizer for defense. In this kind of use, we seek to avoid inadvertent operation which can be very detrimental to neighboring objects, clothes and bags themselves.

On connaît déjà des bout ans poussoirs de sécurité de ce type, comme par exemple ceus lui sont décrits dans les brevets US 3 484 023 et 3 848 778 au nom de Philip Meshberg. Ces dispositifs comportent un bouton poussoir. muni d'un qicleur, emmanché sur la tiqe de soupape d'une valve montée dans l'ouverture d'un récipient. Ils comportent aussi un corps en forme de douille, pour de moyens qui permettent de la fi<er à demeure sur le récipient. Le bouton poussoir peut dais une orientation coulisser axialement dans la douille poir déclencher la valve et commander l'expulsion du liquide contenu dans le réciplent. Il peut aussi tourner pour passer d'une position de fonctionnement dans une orientation, dans laquelle il peut coulisser, à une positior dans une autre orientation dans laquelle il est bloqué axialement, ce qui empêche le déclenchement de la valve.Already known for years safety pushers of this type, as for example those described to him in US Patents 3,484,023 and 3,848,778 in the name of Philip Meshberg. These devices include a push button. fitted with a nozzle, fitted on the valve stem of a valve mounted in the opening of a container. They also have a body in the form of a socket, for means which allow it to be fixed permanently on the container. The push button can have an orientation sliding axially in the socket to trigger the valve and control the expulsion of the liquid contained in the container. It can also rotate to pass from an operating position in one orientation, in which it can slide, to a positior in another orientation in which it is locked axially, which prevents triggering of the valve.

Ces dispositifs, et les dispositifs analocues présentent des inconvénients: il faut faire tourner le bouton poussoir pai rapport à la douille avant de s'en servir. Mais, la douille n'est pas calée en rotation et peut tourner avec le bouton. Pour obtenir le déblocage avec certitude, il faut pratiquement se servir des deux mains. Or, ces dispositifs sort souvent utilisee sar des atomiseurs de défense, praje- tart des produits iacrimogenes. il faut en cas de besgin. pouvoir s'en seivir rapideneri et très preferablement l'une seule main. La fixation de la douille sur le récipient, comme cela est le cas pour les dispositifs des brevets américains ci-dessus, ne permet pas une fixation anti-rotative. En outre, il faut concevoir un bouton spécialement adapté à chaque dimension de récipient.These devices, and the like, have drawbacks: the push button has to be turned in relation to the socket before using it. However, the sleeve is not locked in rotation and can rotate with the button. To obtain the release with certainty, it is practically necessary to use two hands. However, these devices are often used on defense atomizers, mainly iacrimogenic products. it is necessary in case of besgin. to be able to do so quickly and preferably one single hand. The attachment of the sleeve to the container, as is the case for the devices of the above-mentioned US patents, does not allow an anti-rotating attachment. In addition, it is necessary to design a button specially adapted to each size of container.

Cet inconvénient n'existe plus dans les appareils conformes à la présente invention qui a pour objet un dispositif d'actionnement de sécurité pour valve aérosol prévue pour être montée dans l'ouverture d'un récipient d'aérosol au moyen d'une capsule métallique dont la partie centrale est sertie sur la valve et le partie périphérique est sertie sur le bord de l'ouverture du récipient, ledit dispositif d'actionnement comportant une douille cylindrique et un bouton poussoir muni d'un gicleur, prévu pour être emmanché sur la tige de soupape de la valve et pour tourner et coulisser dans la douille cylindrique, remarquable notamment en ce que la douille cylindrique comporte une gorge intérieure adaptée à être fixée par encliquetage sur le sertissage de la capsule sur la valve.This drawback no longer exists in the devices according to the present invention, which relates to a safety actuation device for an aerosol valve intended to be mounted in the opening of an aerosol container by means of a metal capsule. the central part of which is crimped onto the valve and the peripheral part of which is crimped onto the edge of the container opening, said actuating device comprising a cylindrical sleeve and a push button provided with a nozzle, designed to be fitted onto the valve stem of the valve and for turning and sliding in the cylindrical sleeve, remarkable in particular in that the cylindrical sleeve has an internal groove adapted to be fixed by snap-fastening on the crimping of the capsule on the valve.

Le sertissage de la capsule sur la valve a un diamètre nécessairement plus petit que celui du sertissage de la capsule sur le récipient. Il faut donc réaliser un frottement plus élevé entre la douille et la capsule. Mais, parce que ce sertissage est de petit diamètre, il est possible de le réaliser sous forme polyqonale. On peut alors fixer positivement contre la rotation la douille sur le sertissage polygonal.The crimping of the capsule onto the valve necessarily has a smaller diameter than that of the crimping of the capsule onto the container. It is therefore necessary to achieve a higher friction between the sleeve and the capsule. But, because this crimping is of small diameter, it is possible to carry it out in poly q onal form. The sleeve can then be positively fixed against rotation on the polygonal crimp.

La dimension de la douille sera adaptée à la dimension du sertissage, c'est-à-dire à la dimension de la valve. Elle est indépendante de la dimension du récipient.The dimension of the sleeve will be adapted to the dimension of the crimp, that is to say to the dimension of the valve. It is independent of the size of the container.

La douille 1 est formée essentiellement dans un cylindre. Elle possède à un niveau approprié une collerette interne 3 permettant la fixation sur la tourette 21 d'une valve aérosol dont la forme et la structure sont bien connues. La tourett-e 21 est la partie centrale en relief de la capsule 22 qui est sertie autour de la valve 25. La valve comporte dans ce but un bourrelet circulaire 25a à son extrémité externe. La capsule 22 est formée à partir d'une rondelle : la partie centrale 22a est sertie autour du bourrelet 25a de la valve, et la partie extérieure 22b est sertie autour du bord 26a de l'ouverture d'un bidon 1 26, avec interposition d'un joint 27. La valve comporte normalement une tige de soupape 28 et un embout 29 de raccordement d'un tube plongeur. Un tel montage est classique. On désignera par la suite par inférieure l'extrémité de la douille qui est en bas sur les figures 1 et 2 et par supérieure l'extrémité qui est en haut, en remarquant que la douillp 1 et le bouton 2 se placent dans la position représentée sur le haut d'un récipient aérosol, au moyen d'une collerette 3 comme précisé ci-dessus. Le bouton 2, muni d'un gicleur 4, se monte de la façon habituelle sur l'extrémité extérieure tubulaire de la tige de soupape 28. Le diamètre extérieur du bouton 2 est égal au jeu près au diamètre intérieur de la douille 1, et le bouton vient s'engager à l'intérieur de la douille dans laquelle il peut coulisser dans des limites déterminées. Le bord supérieur de la douille comporte deux découpures. Une première découpure 6 est prévue pour dégager le gicleur 4, quand le bouton 2 est dans la douille, à une profondeur et une orientation déterminées. La profondeur est déterminée soit par la collerette 3 sur laquelle prend appui la base du bouton, soit par d'autres moyens décrits ci-après. Pour empêcher le bouton de sortir accidentellement, il est prévu, selon une caractéristique de la présente invention, un accrochage du bouton 2 à l'intérieur de la douille 1. Cet accrochage peut être obtenu par coopération d'une nervure en relief 8, de préférence à la base du bouton 2, avec une autre nervure 9, en relief à l'intérieur de la douille 1, à un niveau au-dessus de la collerette 3 choisi pour coopérer convenablement avec la nervure 8. Les nervures peuvent avoir une section permettant un encliquetage irréversible, ou toute forme de bourrelet. Une des nervures peut être remplacée par une rainure dans laquelle vient s'engager la nervure de l'autre pièce, ou une des nervures peut être constituée par plusieurs segments non jointifs.The sleeve 1 is formed essentially in a cylinder. It has at an appropriate level an internal flange 3 allowing the attachment to the tower 21 of an aerosol valve whose shape and structure are well known. The tourett-e 21 is the central raised part of the capsule 22 which is crimped around the valve 25. The valve has for this purpose a circular bead 25a at its outer end. The capsule 22 is formed from a washer: the central part 22a is crimped around the bead 25a of the valve, and the outer part 22b is crimped around the edge 26a of the opening of a container 1 26, with interposition of a seal 27. The valve normally comprises a valve stem 28 and a nozzle 29 for connecting a dip tube. Such an arrangement is conventional. We will designate below the end of the socket which is at the bottom in Figures 1 and 2 and the upper end which is at the top, noting that the socket p 1 and the button 2 are placed in the position shown on the top of an aerosol container, by means of a flange 3 as specified above. The button 2, fitted with a nozzle 4, is mounted in the usual way on the tubular outer end of the valve stem 28. The outside diameter of the button 2 is equal to the clearance close to the inside diameter of the sleeve 1, and the button engages inside the socket in which it can slide within determined limits. The upper edge of the sleeve has two cutouts. A first cutout 6 is provided to release the nozzle 4, when the button 2 is in the socket, at a determined depth and orientation. The depth is determined either by the collar 3 on which the base of the button rests, or by other means described below. To prevent the button from accidentally coming out, provision is made, according to a characteristic of the present invention, for the button 2 to be hooked inside the socket 1. This hooking can be obtained by cooperation of a raised rib 8, of preferably at the base of the button 2, with another rib 9, in relief inside the sleeve 1, at a level above the flange 3 chosen to cooperate properly with the rib 8. The ribs may have a section allowing an irreversible click, or any form of bead. One of the ribs can be replaced by a groove in which the rib of the other part engages, or one of the ribs can be constituted by several non-contiguous segments.

Le calage en orientation est déterminé par coopération d'une barrette 11, formant une génératrice en relief sur le bouton 2, avec une seconde découpure 12 formée dans la paroi de la douille 1. L'angle ot entre les rayons du bouton passant par la barrette 11 et le gicleur 4 est égal à l'angle des rayons de la capsule passant par le milieu de la découpure 6 et par le milieu de la seconde découpure 12. Le fond 12a de la découpure 12 est assez bas, ainsi que la collerette 3 pour que la bar- rette puisse être enfoncén suffisamment pour déclencher le fonctionnement de la valve. La valve comporte de façon bien connue un ressort qui maintient le bouton 2 en position relevée. La découpure 12 s'étend d'un côté sur une partie de la hauteur, suivant un élargissement 13 permettant de rabattre ou de tourner la barrette 11, en faisant glisser le bas 11a de cette barrette sur le bord inférieur 13a de l'élargissement 13.The setting in orientation is determined by cooperation of a bar 11, forming a raised generator on the button 2, with a second cutout 12 formed in the wall of the socket 1. The angle ot between the spokes of the button passing through the bar 11 and the nozzle 4 is equal to the angle of the rays of the capsule passing through the middle of the cutout 6 and through the middle of the second cutout 12. The bottom 12a of the cutout 12 is quite low, as is the collar 3 for the un- wanted to be sufficient to trigger the enfoncén valve operation. The valve comprises in a well known manner a spring which maintains the button 2 in the raised position. The cutout 12 extends on one side over a part of the height, following an enlargement 13 making it possible to fold or rotate the bar 11, by sliding the bottom 11a of this bar on the lower edge 13a of the enlargement 13 .

Dans la forme de réalisation représentée, la barrette 11 du bouton 2 s'étend sur toute la hauteur du bouton 2. On comprendra que c'est une commodité appréciable pour actionner le bouton en rotation autour de son axe, mais que la barrette pourrait ne pas s'étendre jusqu'à l'une et/ou l'autre des extrémités. Les niveaux 12a et 13a des fonds de la découpure 12 et de l'élargissement 13 sont prévus en conséquence. Les hauteurs respectives auxquelles sont formées les nervures 8 et 9 sont choisies pour que ces nervures soient encliquetées quand le bas 11a de la barrette 11 vient en appui sur le fond 13a de l'élargissement 13. Le bouton 2 ne peut donc remonter et sortir de la douille en raison de la présence de ces nervures 8 et 9, mais rien ne l'empêche de descendre avec l'orientation convenable, jusqu'à ce que le fond du bouton vienne buter contre la collerette 3 ou jusqu'à ce que le bas 11a de la barrette vienne buter sur le fond 12a de la découpure 12, ou encore jusqu'à ce que la tige de soupape, sur laquelle est emmanché le bouton, arrive en butée basse. Afin d'éviter un accrochage de la barrette 11 par des objets voisins dans une poche, un sac ou une valise, l'épaisseur en sens radial de la barrette 11 est égale ou inférieure à l'épaisseur de la paroi de la douille. Elle ne présente ainsi aucun saillant latéral. Pour faciliter l'actionnement, la face extérieure de la barrette peut présenter un rainurage, un moletage ou analogue. Afin de faciliter l'attaque de la barrette 11 par le doigt de l'utilisateur, il est prévu de chaque côté de la découpure 12 avec l'élargissement 13, un dégagement 15, 16 laissant à ces endroits une paroi amincie 15a, 16a.In the embodiment shown, the bar 11 of the button 2 extends over the entire height of the button 2. It will be understood that it is an appreciable convenience for actuating the button in rotation about its axis, but that the bar could not not extend to one and / or the other of the ends. The levels 12a and 13a of the bottoms of the cutout 12 and the widening 13 are provided accordingly. The respective heights at which the ribs 8 and 9 are formed are chosen so that these ribs are snapped when the bottom 11a of the bar 11 comes to bear on the bottom 13a of the enlargement 13. The button 2 cannot therefore go up and out of the socket due to the presence of these ribs 8 and 9, but nothing prevents it from going down with the correct orientation, until the bottom of the button abuts against the flange 3 or until the bottom 11a of the bar comes up against the bottom 12a of the cutout 12, or even until the valve stem, on which the button is fitted, reaches the bottom stop. In order to avoid the bar 11 being caught by neighboring objects in a pocket, bag or suitcase, the thickness in the radial direction of the bar 11 is equal to or less than the thickness of the wall of the sleeve. It therefore has no lateral projection. To facilitate actuation, the outer face of the bar may have grooving, knurling or the like. To facilitate the attack of the bar 11 by the finger of the user, there is provided on each side of the cutout 12 with the widening 13, a clearance 15, 16 leaving at these locations a thinned wall 15a, 16a.

Selon une caractéristique importante de la présente invention, la gorge 3a de la collerette 3 délimite une ouverture polygonale, de périmètre identique à celui du rétreint 22c du sertissage du bord central 22a de la coupelle, juste en-dessous du bourrelet 25a de la valve 25. Ce sertissage de petit diamètre peut être réalisé facilement à la forme d'un hexagone, et avec une douille présentant une ouverture hexagonale comme représenté sur la figure 4 ; on a un excellent calage en rotation.According to an important characteristic of the present invention, the groove 3a of the collar 3 defines a polygonal opening, with a perimeter identical to that of the constriction 22c of the crimping of the central edge 22a of the cup, just below the bead 25a of the valve 25 This crimping of small diameter can easily be carried out in the form of a hexagon, and with a socket having a hexagonal opening as shown in FIG. 4; we have an excellent rotation setting.

Le dispositif est utilisé de la façon suivante. La douille 1 est emmanchée sur la tourette 21 de la capsule 22 d'une valve aérosol 25 montée sur un bidon 26. Le bouton 2 est placé dans l'axe de la douille, la barrette 11 étant orientée pour être au droit de l'élargissement 13. On enfonce alors le bouton jusqu'à la butée du bas 11a de la barrette sur le fond 13a de l'élargissement, en provoquant l'encliquetage de la nervure 8 du bouton 2 sous la nervure 9. Le dispositif est alors prêt à être utilisé ; il est en position de sécurité : la barrette 11 bute sur le fond 13a de l'élargissement 13 et le gicleur 4 est masqué par la paroi de la douille 1. Par une poussée d'un doigt contre la barrette, on amène celle-ci au-dessus de la découpure 12, ce qui est facilité par le dégagement 15. Pendant ce mouvement, la douille ne peut pas tourner en raison de la liaison hexagonale de la gorge 3a sur le rétreint 22c du sertissage. Le gicleur apparaît alors dans la découpure 6. On peut alors enfoncer le bouton 2 pour déclencher le fonctionnement de la valve. Après actionnement, on repousse la barrette 11 en position verrouillée, par une poussée en sens inverse, ce qui est facilité par le dégagement 16. L'utilisateur tient le corps du bidon dans la main, il tourne la barrette 11 avec le pouce, et il appuie sur le dessus du bouton 2 avec un doigt. Le verrouillage de la douille sur la tourette 21 de la capsule permet ce mouvement avec sûreté, sans risque de voir la douille tourner en même temps que le bouton.The device is used in the following manner. The sleeve 1 is fitted onto the spinner 21 of the capsule 22 of an aerosol valve 25 mounted on a canister 26. The button 2 is placed in the axis of the sleeve, the bar 11 being oriented to be in line with the enlargement 13. The button is then pushed in until the bottom stop 11a of the bar on the bottom 13a of the enlargement, causing the rib 8 of the button 2 to snap under the rib 9. The device is then ready to be used; it is in the safety position: the bar 11 abuts on the bottom 13a of the enlargement 13 and the nozzle 4 is masked by the wall of the sleeve 1. By pushing a finger against the bar, the latter is brought in above the cutout 12, which is facilitated by the clearance 15. During this movement, the sleeve cannot rotate due to the hexagonal connection of the groove 3a on the constriction 22c of the crimping. The nozzle then appears in the cutout 6. You can then press the button 2 to trigger the operation of the valve. After actuation, the bar 11 is pushed back into the locked position, by a push in the opposite direction, which is facilitated by the release 16. The user holds the body of the container in his hand, he turns the bar 11 with his thumb, and he presses the top of button 2 with a finger. The locking of the socket on the screwdriver 21 of the capsule allows this movement with safety, without the risk of seeing the socket rotate at the same time as the button.

La figure 5 représente en détail en coupe, l'assemblage de la douille 1 au moyen de la gorge 3a de la collerette 3 coopérant avec le rétreint 22c du sertissage. La dimension de la gorge 3a est adaptée à celle de la valve 25, en particulier à son diamètre extérieur. Le bas la de la douille vient se placer au voisinage de la paroi du bidon 26. On voit qu'avec la fixation de la présente invention, l'ensemble douille/bouton-poussoir peut être monté sur des bidons de différentes dimensions. Il suffit d'utiliser sur la valve 25 une coupelle adaptée au bidon.Figure 5 shows in detail in section, the assembly of the sleeve 1 by means of the groove 3a of the flange 3 cooperating with the constriction 22c of the crimping. The dimension of the groove 3a is adapted to that of the valve 25, in particular to its outside diameter. The bottom of the socket is placed in the vicinity of the wall of the container 26. It can be seen that with the fixing of the present invention, the socket / push button assembly can be mounted on containers of different dimensions. It suffices to use on the valve 25 a cup adapted to the container.

Sur la figure 6, on a représenté la partie supérieure d'un bidon 30 dans le goulot duquel est montée une valve au moyen d'une capsule 31. La tourette (turret) 32 de la capsule est sertie sur la valve par un rétreint hexagonal dans lequel est engagé le bord interne de la collerette 35 de la douille 36. Avec une telle capsule qui émerge au-dessus du bord du bidon, la collerette 35 peut être entièrement plane, il n'y a pas besoin d'une jupe pour réaliser un serrage dans le creux d'une coupelle. Avec des capsules de ce type on peut monter des valves de 10 ou 12 mm de diamètre par exemple, dans des capsules permettant d'effectuer des sertissages sur des embouchures de bidons de 14 à 21 mm de diamètre par exemple. Le diamètre intérieur de la douille 36 peut être de 22 mm, correspondant au diamètre extérieur du bouton-poussoir. Ceci met en évidence la possibilité d'utiliser un bouton-poussoir avec sa douille, associé à une valve, sur des bidons d'ouvertures de différentes dimensions.In FIG. 6, the upper part of a container 30 is shown in the neck of which a valve is mounted by means of a capsule 31. The turret 32 of the capsule is crimped on the valve by a hexagonal constriction in which is engaged the internal edge of the collar 35 of the sleeve 36. With such a capsule which emerges above the edge of the container, the collar 35 can be entirely flat, there is no need for a skirt to tighten in the hollow of a cup. With capsules of this type, valves 10 or 12 mm in diameter can be mounted, for example, in capsules allowing crimping to be made on the mouths of cans of 14 to 21 mm in diameter, for example. The inside diameter of the socket 36 can be 22 mm, corresponding to the outside diameter of the push button. This highlights the possibility of using a push button with its socket, associated with a valve, on canisters of openings of different dimensions.

Il va de soi que le mode de réalisation décrit n'est qu'un exemple, et qu'il serait possible de le modifier, notamment par substitution d'équivalents techniques, sans sortir pour cela du cadre de l'invention.It goes without saying that the embodiment described is only an example, and that it would be possible to modify it, in particular by substitution of technical equivalents, without departing from the scope of the invention.
