Abstract

A push button (2) is slidably and rotatably mounted in a sleeve (1). The push button is fitted to the valve-operating rod (28) of an aerosol valve (25) fitted in the opening of an aerosol can (26) by means of a dish (22). The inside edge of the dish is crimped to the valve and its outside edge is crimped to the edges of the can. The sleeve has an internal collar (3) which is snap fitted over the neck where the inside edge of the dish is crimped to the valve. Since the sleeve thus engages the valve rather than the can, sleeve size and shape is independent of the size and shape of the can (in so far as there are relatively few valve sizes used in a wide range of can shapes and sizes). Further, by crimping the neck (22c) so that its periphery is polygonal, the sleeve can be prevented from rotating. A safety push button requiring both a turning action and an axial displacement for operation, can thus readily be operated with one hand since there is no need to use the other hand to stop the sleeve from rotating.

Description

La présente invention a pour objet un dispositif d'actionnement de sécurité pour valve 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, ou 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 eux-mêmes.The present invention relates to a safety actuating device for an aerosol valve. Such a safety device can be used for example for aerosol cans intended to be placed in a pocket, a bag or a 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, clothing and bags themselves.

L'invention s'applique plus particulièrement à 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 mélallique dont la partie centrale est sertie sur la valve et la partie périphérique est sertie sur le bord de l'ouverture du récipient, ledit dispositif d'actionnement comportant une douille cylindrique fixée par encliquetage sur le sertissage de la capsule sur la valve 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, et dans lequel le bouton poussoir comporte un élément en relief latéral tel qu'une barrette facilitant l'actionnement en rotation dudit bouton poussoir, cet élément en relief étant engagé dans une découpure formée dans la douille.The invention applies more particularly to a safety actuating device for an aerosol valve intended to be mounted in the opening of an aerosol container by means of a metal capsule whose central part is crimped onto the valve. and the peripheral part is crimped on the edge of the opening of the container, said actuating device comprising a cylindrical sleeve fixed by snap-fastening on the crimping of the capsule on the valve and a push button provided with a nozzle, designed to be fitted on the valve stem of the valve and for turning and sliding in the cylindrical sleeve, and in which the push button comprises a lateral raised element such as a bar facilitating the rotary actuation of said push button, this raised element being engaged in a cutout formed in the socket.

On connaît déjà des boutons poussoirs de sécurité de ce type, comme par exemple ceux qui sont décrits dans le document GB-A-768 734 au nom de Dodge & Seymour, Ltd. Ces dispositifs comportent un bouton poussoir, muni d'un gicleur, emmanché sur la tige de soupape d'une valve montée dans l'ouverture d'un recipient. Ils comportent aussi un corps en forme de douille, pourvu de moyens qui permettent de la fixer sur le récipient par encliquetage sur le sertissage de la capsule sur la valve. L'enfoncement du poussoir dans la douille ne peut être fait que pour certaines positions angulaires relatives du poussoir par rapport à la douille.Safety pushbuttons of this type are already known, for example those described in document GB-A-768 734 in the name of Dodge & Seymour, Ltd. 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 include a socket-shaped body, provided with means which allow it to be fixed on the container by snap-fastening on the crimping of the capsule on the valve. The insertion of the pusher into the sleeve can only be done for certain relative angular positions of the pusher relative to the sleeve.

Un moyen de sécurité analogue est décrit dans le document FR-A-2 310 282 de la demanderesse, qui concerne un dispositif de verrouillage à l'enfoncement d'un bouton poussoir, comprenant une embase fixée au récipient et munie d'élément formant cames coopérant avec des reliefs appropriés du bouton poussoir. Pour empêcher la rotation de l'embase, celle-ci comporte sur sa sa face cylindrique intérieure des reliefs venant se loger contre des dépressions de la partie centrale de la capsule.A similar security means is described in document FR-A-2 310 282 by the applicant, which relates to a device for locking when a push button is pressed, comprising a base fixed to the container and provided with cam element. cooperating with appropriate reliefs of the push button. To prevent rotation of the base, it has on its inner cylindrical face reliefs which are housed against depressions in the central part of the capsule.

La présente invention a pour objet un dispositif plus efficace, plus facile à manier, et de prix de revient limité.The present invention relates to a more efficient device, easier to handle, and of limited cost price.

La présente invention a pour objet un dispositif d'actionnement de sécurité pour valve aérosol du type ci-dessus, remarquable notamment en ce que les bords de la découpe latérale de la douille sont amincis, de façon à former des dégagements pour permettre de saisir plus facilement la barrette.The present invention relates to a safety actuating device for aerosol valve of the above type, remarkable in particular in that the edges of the lateral cutout of the sleeve are thinned, so as to form clearances to allow more grip easily the bar.

Dans une forme de réalisation avantageuse, la douille comporte une collerette intérieure qui porte sur son bord interne les moyens d'encliquetage de la douille sur le sertissage de la capsule sur la valve.In an advantageous embodiment, the sleeve has an internal collar which carries on its internal edge the means for latching the sleeve on the crimping of the capsule on the valve.

La douille 1 est formée essentiellement dans un cylindre. Elle possède à 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 tourette 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 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 douille 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 tubulairé 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. At an appropriate level, it has an internal collar 3 allowing the aerosol valve, the shape and structure of which are well known, to be attached to the tower 21. The spinner 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 26, with interposition d '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 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 expensive button accidentally exit, there is provided, according to a feature of the present invention, an attachment of the button 2 inside the sleeve 1. This attachment can be obtained by cooperation of a raised rib 8, 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 a 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 barrete puisse être enfoncée 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 11 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 a 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 so that the bar can be pressed enough to trigger the operation of the valve. 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 portion of the height, following an enlargement 13 making it possible to fold or turn the bar 11, by sliding the bottom 11 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 11 a 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 in 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 collar 3 or until the bottom 11a of the bar comes to abut on 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. In order 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 places 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 perimètre identique à celui du rétreint 22c du sertissage du bord central 22a de la coupelle, juste en-dessous du bourrelet 25a de la valve 24. 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, of 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 24 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 11 a 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 snap of the rib 8 of the button 2 under the rib 9. The device is then ready to use; 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 1 a 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 1a 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 flange 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 making it possible to crimp on the mouths of cans of 14 to 21 mm in diameter, for example. The inside diameter of the sleeve 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.
