Description

La présente invention a pour objet un dispositif de sécurité pour vaporisateur d'aérosol, et plus particulièrement pour les pompes et bombes qui comportent un poussoir formé de deux ailettes servant de repose-doigts. Certains embouts de pulvérisation comportent un gicleur dans l'axe de poussée (exemple: vaporisateur nasal) et l'actionnement ne peut donc être effectué par une poussée exercée directement sur ce même axe ; d'où l'emploi des ailettes, servant de repose-doigts. Ces repose-doigts, du fait de leur forme, compliquent le moulage des embouts et limitent les possibilités de conception. L'invention vise en particulier à assurer la sécurité d'usage ou de transport, c'est-à-dire l'interdiction d'un fonctionnement involontaire, et la sécurité d'inviolabilité jusqu'au premier emploi, pour le flacon (et son contenu) et pour le mécanisme de la pompe ou de la soupape. Ces résultats peuvent être obtenus de façon connue en adjoignant une bague déchirable à l'embout ou au capuchon de protection destiné à recouvrir et protéger l'embout en dehors des périodes de service. Cette bague peut empêcher l'enfoncement de l'embout, donc son fonctionnement. L'embout ne peut être enfoncé qu'après enlèvement de la bague, par déchirure d'un certain nombre de points ou de lignes d'attache. Mais la fabrication, le moulage d'un embout avec des repose-doigts en forme d'ailes latérales, et avec une bague déchirable, est une opération délicate et coûteuse, exigeant des moules compliqués.The present invention relates to a safety device for aerosol spray, and more particularly for pumps and bombs which comprise a pusher formed by two fins serving as finger rests. Some spray tips have a nozzle in the thrust axis (example: nasal spray) and actuation cannot therefore be effected by a thrust exerted directly on this same axis; hence the use of fins, serving as a finger rest. These finger rests, because of their shape, complicate the molding of the tips and limit the design possibilities. The invention aims in particular to ensure the security of use or transport, that is to say the prohibition of involuntary operation, and the security of inviolability until the first use, for the bottle (and contents) and for the pump or valve mechanism. These results can be obtained in a known manner by adding a tearable ring to the end piece or to the protective cap intended to cover and protect the end piece outside periods of service. This ring can prevent the tip from sinking, and therefore its operation. The tip can only be inserted after removing the ring, by tearing a certain number of points or attachment lines. But the manufacture, the molding of a tip with finger rests in the form of lateral wings, and with a tearable ring, is a delicate and expensive operation, requiring complicated molds.

Conformément à la présente invention, on parvient à obtenir un dispositif pratique, commode et peu coûteux en réalisant un embout dont le repose-doigts en forme d'ailes est constitué par une pièce indépendante de l'embout. Dans le dispositif de l'invention, l'embout est monté de façon à pouvoir tourner sur lui-même autour de l'axe de poussée et le dispositif comporte une douille entourant la tige de soupape et l'embout. Cette douille est formée avec deux découpures diamétralement opposées, permettant le passage des ailes des repose-doigts quand elles sont placées angulairement en regard des découpures. Quand l'embout avec les ailes est tourné, il ne peut plus être actionné, les bras formés sur la douille entre les découpures empêchant la descente des repose-doigts. Le dispositif comporte ainsi, en plus de la soupape : un embout, un capuchon et une douille. Selon l'invention, le repose-doigts peut être moulé avec le capuchon, pour en être détaché au moment du premier emploi, ou il peut être moulé séparément. La douille peut être fabriquée indépendamment, ou peut être moulée avec le capuchon, pour en être détachée au moment du premier emploi.In accordance with the present invention, it is possible to obtain a practical, convenient and inexpensive device by producing a tip, the wing-shaped finger rest consists of a piece. independent of the nozzle. In the device of the invention, the end piece is mounted so as to be able to rotate on itself around the thrust axis and the device comprises a socket surrounding the valve stem and the end piece. This socket is formed with two diametrically opposite cutouts, allowing the wings of the finger rests to pass when they are placed angularly opposite the cutouts. When the tip with the wings is turned, it can no longer be actuated, the arms formed on the socket between the cutouts preventing the finger rests from lowering. The device thus comprises, in addition to the valve: a nozzle, a cap and a socket. According to the invention, the finger rest can be molded with the cap, to be detached from it at the time of the first use, or it can be molded separately. The sleeve can be made independently, or can be molded with the cap, to be detached at the time of first use.

Sur la figure 1, est représenté un bidon 1 muni d'une v alve 2. Celle-ci peut être une valve à enfoncement, organisée pour libérer un produit sous pression contenu dans le bidon, ou peut être une pompe, dont l'actionnement expulse le contenu du bidon. La valve 2 peut être sertie ou vissée sur le col du bidon, de préférence avec un système anti-dévissage du genre cran à encliquetage irréversible pour garantir à l'acheteur l'intégrité du contenu du bidon. Autour de la valve 2, est disposée une douille 3 cylindrique, dont la partie supérieure est formée avec des découpures 3a, 3b, délimitant entre elles des bras 3c, 3d. La douille peut être moulée avec le bidon, si celui-ci est en matière moulée, ou fixée au bidon de toute façon approprié. De préférence, elle doit être fixe et ne pas pouvoir tourner autour du dibon pour faciliter le fonctionnement et l'emploi. Sur la valve, est monté un embout pulvérisateur 4 muni à son extrémité d'un gicleur 5. Comme il n'est pas possible de libérer le produit du bidon en appuyant sur l'extrémité de l'embout, c'est-à-dire en fait sur le gicleur qui serait alors obstrué, l'embout est actionné par un repose-doigts 6 en forme d'une virole 6a munie de deux ailes 6b, 6c (figure 4). Le repose-doigts est distinct de l'embout, et est livré au consommateur séparément, dans le même emballage. Le repose-doigts 6 est, de préférence, calé sur la partie cylindrique 4a de l'embout 4, et prend appui vers le bas sur une bride formée à la base de l'embout. Pour obtenir un bon calage, l'alésage du repose-doigts peut comporter un méplat, ou la partie cylindrique 4a de l'embout peut être légèrement conique et/ou avoir une section non circulaire. On voit que, si le repose-doigts est tourné de façon que les ailes 6b, 6c puissent s'engager entre les bras 3c, 3d de la douille 3, on pourra actionner l'embout et extraire le produit contenu dans le bidon. Si le repose-doigts est tourné suffisamment, de préférence à 90° de la position précédente, il ne pourra être enfoncé, et l'on ne pourra actionner la valve.In Figure 1, there is shown a container 1 provided with a v alve 2. This can be a push-in valve, organized to release a pressurized product contained in the container, or can be a pump, of which actuation expels the contents of the container. The valve 2 can be crimped or screwed onto the neck of the container, preferably with an anti-unscrewing system of the notch type with irreversible latching to guarantee the buyer the integrity of the contents of the container. Around the valve 2, is arranged a cylindrical socket 3, the upper part of which is formed with cutouts 3a, 3b, delimiting between them arms 3c, 3d. The socket can be molded with the container, if the latter is made of molded material, or fixed to the container in any suitable manner. Preferably, it must be fixed and not able to rotate around the dibon to facilitate operation and use. On the valve, is mounted a spray nozzle 4 provided at its end with a nozzle 5. As it is not possible to release the product from the container by pressing on the end of the nozzle, that is to say say in fact on the nozzle which would then be obstructed, the endpiece is actuated by a finger rest 6 in the form of a ferrule 6a provided with two wings 6b, 6c (FIG. 4). The finger rest is separate from the tip, and is delivered to the consumer separately, in the same packaging. The finger rest 6 is preferably wedged on the cylindrical part 4a of the end piece 4, and bears downwards on a flange formed at the base of the end piece. To obtain a good setting, the bore of the finger rest may have a flat, or the cylindrical part 4a of the end piece may be slightly conical and / or have a non-circular section. We see that, if the finger rest is rotated so that the wings 6b, 6c can engage between the arms 3c, 3d of the sleeve 3, we can activate the tip and extract the product contained in the container. If the finger rest is turned enough, preferably 90 ° from the previous position, it cannot be pushed in, and the valve cannot be actuated.

Le dispositif de cette première forme de réalisation de l'invention comporte encore un capuchon 7 et une bague d'inviolabilité 8. Le capuchon 7 et la bague 8 sont réunis par des tenons cassables 9 pour former une pièce moulée PM1 indépendante. La bague porte d'autres tenons cassables 10 prévus pour coopérer avec un cercle 11 fixé à la douille 3 par des tenons cassables 12. La forme des tenons 10 permet de les encliqueter sous le cercle 12, mais il n'est pas possible d'extraire les tenons 10 du cercle 11 sans briser les tenons 10 ou les tenons 12.The device of this first embodiment of the invention also comprises a cap 7 and a tamper-evident ring 8. The cap 7 and the ring 8 are joined by breakable pins 9 to form a molded piece PM1 independent. The ring carries other breakable tenons 10 provided to cooperate with a circle 11 fixed to the socket 3 by breakable tenons 12. The shape of the tenons allows them to be snapped under the circle 12, but it is not possible to extract the tenons from the circle 11 without breaking the tenons or the tenons 12.

La figure 2 représente, à l'état assemblé, les deux parties du dispositif représenté sur la figure 1 tel qu'il est expédié au vendeur. Pour mettre l'appareil en service, il faut briser les tenons 9, et les tenons 10 ou 12 (de préférence les deux séries) ; on jette la bague 8, on enfile le repose-doigts 6 sur l'embout 4, et on peut actionner l'appareil aprés avoir orienté convenablement le repose-doigts. Après usage, le repose-doigts est tourné en position de sécurité, et on place le capuchon. Des encliquetages appropriés, de type connu, permettant de caler provisoirement le repose-doigts en position de sécurité. L'appareil en état de service est représenté sur la figure 3.Figure 2 shows, in the assembled state, the two parts of the device shown in Figure 1 as it is shipped to the seller. To put the device into service, it is necessary to break the pins 9, and the pins 10 or 12 (preferably the two series); the ring 8 is thrown away, the finger rest 6 is threaded onto the end piece 4, and the device can be actuated after having correctly oriented the finger rest. After use, the finger rest is turned to the safety position, and the cap is placed. Appropriate snaps, of known type, making it possible to temporarily lock the finger rest in the safety position. The device in working order is shown in Figure 3.

Les figures 5 à 8 représentent une variante de réalisation de l'invention, dans laquelle le repose-doigts, au lieu d'être livré indépendamment, est moulé avec le capuchon, et forme avec ce dernier et la bague de garantie, une pièce moulée indépendante PM2. Le repose-doigts est séparé par l'utilisateur au moment de l'emploi. Le bidon 1 n'est pas représenté pour cause de simplication. On voit l'embout et la douille 3 qui l'entoure avec des bras 3c et 3d séparés par les découpures 3a et 3b. La seconde partie est constituée par une pièce moulée PM2 en matière plastique, comportant un capuchon 7, un repose-doigts 6 et une bague 8. Cette bague est munie des tenons 10, coopérant avec le cercle 11 solidaire du récipient par l'intermediaire des tenons 12. Le capuchon 7 est connecté au repose-doigts 6, par des tenons cassables 76 et le repose-doigts 6 est connecté à la bague 8 par des tenons cassables 68. L'ensemble monté est représenté sur la figure 6.Figures 5 to 8 show an alternative embodiment of the invention, in which the finger rest, instead of being delivered independently, is molded with the cap, and forms with the latter and the guarantee ring, a molded part independent PM2. The finger rest is separated by the user at the time of use. The container 1 is not shown for simplicity. We see the tip and the socket 3 which surrounds it with arms 3c and 3d separated by the cutouts 3a and 3b. The second part is constituted by a molded part PM2 made of plastic material, comprising a cap 7, a finger rest 6 and a ring 8. This ring is provided with tenons 10, cooperating with the circle 11 secured to the container by means of pins 12. The cap 7 is connected to the finger rest 6, by breakable pins 76 and the finger rest 6 is connected to the ring 8 by breakable pins 68. The assembled assembly is shown in FIG. 6.

Pour la mise en service (voir figures 7 et 8), l'utilisateur brise les tenons 76, 68, 10 et 12. Le cercle 11 est jeté avec les morceaux de tenons. Le repose-doigts est mis en place et l'ensemble est prêt à fonctionner (figure 8).For commissioning (see Figures 7 and 8), the user breaks the pins 76, 68, 10 and 12. The circle 11 is thrown with the pieces of pins. The finger rest is put in place and the assembly is ready to operate (Figure 8).

Les figures 9 à 13 représentent une variante d'exécution de la présente invention, dans laquelle le capuchon 7 est moulé en une seule pièce PM3 avec la douille 3 portant les bras et découpures de sécurité 3a, 3b, 3c, 3d, avec des tenons cassables 73. A la différence des réalisations précédentes, la douille n'est initialement pas solidaire du bidon, mais vient s'y fixer par clipsage -ou encliquetage-, irréversible, au moment de l'expédition chez le distributeur (voir figure 10). Pour mettre l'appareil en service, l'utilisateur devra briser les tenons 73 (figure 11), ce qui libère le capuchon, et placer un repose-doigts, livré avec le bidon, mais non solidaire de celui-ci. L'appareil est alors prêt à l'emploi (figure 12) et après usage, peut être mis en position de sécurité par rotation de 90° (figure 13).Figures 9 to 13 show an alternative embodiment of the present invention, in which the cap 7 is molded in one piece PM3 with the sleeve 3 carrying the arms and safety cutouts 3a, 3b, 3c, 3d, with pins breakable 73. Unlike the previous embodiments, the sleeve is not initially secured to the container, but is fixed there by clipping -or snap-fastening, irreversible, at the time of shipment to the distributor (see Figure 10) . To put the device into service, the user will have to break the pins 73 (figure 11), which frees the cap, and place a finger rest, supplied with the container, but not integral with it. The device is then ready to use (figure 12) and after use, can be put in the safety position by 90 ° rotation (figure 13).

De même que pour le mode de réalisation des figures 5 à 8, la pièce moulée PM4 des figures 14a et 14b inclut le repose-doigts. Le capuchon est connecté par des tenons cassables 76 au repose-doigts 6, qui est connecté par des tenons cassables 63 à la douille 3. Dans la variante de la figure 14a, la douille 3 est montée par vissage sur le col d'un bidon, flacon ou similaire, de préférence avec un cran de blocage irréversible (indévissable). Dans la variante de la figure 14b, la douille 3 est du type encliquetable (snap-on) directement sue le col d'un flacon, pour y monter la valve 2 avec interposition d'un joint 20. Pour le reste, ces deux réalisations sont équivalentes. Le produit est expédié au vendeur sous la forme représentée à la figure 15a ou 15b. L'utilisateur, pour mettre en service le dispositif, casse les tenons 76 et 63 (figures 14c et 16a), et descend le repose-doigts à sa position de service sur l'embout 2. Il place ensuite le capuchon (figure 15a). Quand le dispositif est en position de sécurité (figures 15a et 15b), les ailes 6b et 6c du repose-doigts sont appliquées sur les bras 3c et 3d de la bouille 3 : le repose-doigts ne peut descendre et le dispositif ne peut éjecter de produit. Quand le repose-doigts est tourné de 90° (figures 16a et 16b), il peut descendre dans les découpures 3a et 3b de la douille 3, et le produit peut être éjecté (figure 16b). La surface inférieure 62 du repose-doigts, située dans un plan axial, prend appui, en position de service contre une bride ou un épaulement 65 de l'embout, ce qui assure l'entraînement positif de ce dernier, quelque soit par ailleurs l'état de coincement entre les surfaces concentriques en contact de l'embout et du repose-doigts.As for the embodiment of Figures 5 to 8, the molded part PM4 of Figures 14a and 14b includes the finger rest. The cap is connected by breakable pins 76 to the finger rest 6, which is connected by breakable pins 63 to the sleeve 3. In the variant of FIG. 14a, the sleeve 3 is mounted by screwing on the neck of a container. , bottle or the like, preferably with an irreversible (unscrewable) locking catch. In the variant of FIG. 14b, the sleeve 3 is of the snap-on type directly on the neck of a bottle, for mounting the valve 2 therewith the interposition of a seal 20. For the rest, these two embodiments are equivalent. The product is shipped to the seller in the form shown in Figure 15a or 15b. The user, to put the device into service, breaks the pins 76 and 63 (Figures 14c and 16a), and lowers the finger rest to its service position on the end piece 2. He then places the cap (Figure 15a) . When the device is in the safety position (Figures 15a and 15b), the wings 6b and 6c of the finger rest are applied to the arms 3c and 3d of the boil 3: the finger rest cannot descend and the device cannot eject of product. When the finger rest is rotated 90 ° (Figures 16a and 16b), it can descend into the cutouts 3a and 3b of the sleeve 3, and the product can be ejected (Figure 16b). The lower surface 62 of the finger rest, located in an axial plane, bears, in the service position against a flange or a shoulder 65 of the endpiece, which ensures the positive drive of the latter, whatever is otherwise l state of jamming between the concentric surfaces in contact with the nozzle and the finger rest.

Afin d'avoir un fonctionnement correct assuré du dispositif, on peut prévoir sur la surface extérieure de la virole 6a du repose-doigts 6 des nervures radiales 61 (au moins une) coopérant avec des rainures 31 formées dans la surface interne de la douille 3 (voir figure 17). Les encliquetages ainsi déterminés définissent deux positions du repose-doigts, à angle droit, l'une de l'autre. L'une dans laquelle l'embout peut être enfoncé à l'aide du repose-doigts, et une position de sécurité dans laquelle il ne peut être enfoncé. Grâce à cet encliquetage, l'embout reste à la position où il est placé. Si l'on désire appuyer, il s'enfonce, et mis en sécurité, il ne s'en écarte pas fortuitement par l'effet d'un mouvement aléatoire, dans un sac par exemple. In order to ensure correct operation of the device, radial ribs 61 (at least one) cooperating with grooves 31 formed in the internal surface of the sleeve 3 can be provided on the outer surface of the ferrule 6a of the finger rest 6 (see figure 17). The snaps thus determined define two positions of the finger rest, at right angles to one another. One in which the tip can be pushed in using the finger rest, and a safety position in which it cannot be pushed in. With this snap, the tip remains in the position where it is placed. If one wishes to press, it sinks, and put in safety, it does not depart from it fortuitously by the effect of a random movement, in a bag for example.
