Description
L'invention est relative à une valve pour bidon aérosol, valve du genre de celles qui permettent la pulvérisation d'un produit contenu sous pression gazeuse dans le bidon et qui comprennent un corps fixé sur le bidon et faisant saillie vers l'intérieur de ce bidon, et une tige d'actionnement, accessible de l'extérieur du bidon, et propre à être déplacée, par l'action d'un utilisateur, pour commander l'ouverture de la valve selon le préambule de la revendication 1.The invention relates to a valve for an aerosol canister, a valve of the kind which allows the spraying of a product contained under gas pressure in the canister and which comprises a body fixed on the canister and projecting inwards from it. container, and an actuating rod, accessible from outside the container, and capable of being moved, by the action of a user, to control the opening of the valve according to the preamble of
Lorsque l'on pulvérise un produit, notamment de la laque pour cheveux, il est souhaitable d'obtenir, pendant toute la durée d'utilisation du bidon, une bonne qualité de pulvérisation, c'est-à-dire un débit et une taille convenables des gouttelettes pulvérisées. Ce problème se pose notamment lorsque la pression gazeuse à l'intérieur du bidon est assurée avec un gaz comprimé (N2, CO2 ou air), car la pression diminue progressivement au cours des utilisations répétées.When spraying a product, in particular hairspray, it is desirable to obtain, throughout the duration of use of the container, a good quality of spraying, that is to say a flow rate and a size suitable droplets sprayed. This problem arises in particular when the gas pressure inside the container is ensured with a compressed gas (N2, CO2 or air), since the pressure gradually decreases during repeated use.
L'invention a pour but, surtout, de fournir une valve qui permet de résoudre ce problème en empêchant automatiquement toute pulvérisation lorsque la pression à l'intérieur du bidon devient inférieure à une pression prédéterminée, considérée comme minimale pour assurer une pulvérisation convenable. Dans le cas d'un bidon pouvant être rechargé en gaz propulseur comprimé, l'utilisateur sera ainsi averti d'avoir à recharger le bidon en gaz comprimé.The object of the invention is, above all, to provide a valve which makes it possible to solve this problem by automatically preventing any spraying when the pressure inside the can becomes lower than a predetermined pressure, considered as minimum to ensure a suitable spraying. In the case of a can that can be recharged with compressed propellant gas, the user will thus be warned to have to refill the can with compressed gas.
On a déjà proposé, selon US-A-3 018 928, de combiner une telle valve avec un clapet propre à se trouver à l'intérieur du bidon et comportant un organe mobile soumis à l'action d'un ressort taré de manière telle que, lorsque la pression dans le bidon devient inférieure à une limite prédéterminée, le clapet empêche toute pulvérisation même si la tige de valve est actionnéeIt has already been proposed, according to US-A-3,018,928, to combine such a valve with a valve suitable for being inside the container and comprising a movable member subjected to the action of a spring calibrated in such a way that, when the pressure in the container falls below a predetermined limit, the valve prevents spraying even if the valve stem is actuated
L'invention a pour but de fournir une telle valve qui soit d'une réalisation simple et économique et qui puisse être réalisée aisément à partir de valves classiques ne permettant pas d'empêcher automatiquement la pulvérisation à partir d'une certaine pression minimale.The object of the invention is to provide such a valve which is of a simple and economical embodiment and which can be produced easily from conventional valves which does not make it possible to automatically prevent spraying from a certain minimum pressure.
Selon l'invention, une valve pour bidon aérosol du genre défini précédemment est caractérisée par le fait que la combinaison de la valve et du clapet est telle que, le corps de valve ayant une entrée et le clapet comprenant une enveloppe tubulaire recouvrant ladite entrée, l'organe mobile du clapet est arrangé de telle manière que le passage du produit constitué par l'entrée et l'enveloppe puisse être fermé, le clapet ne s'ouvrant que pour une pression, à l'intérieur du réservoir, au moins égale à la susdite limite prédéterminée.According to the invention, a valve for aerosol can of the kind defined above is characterized in that the combination of the valve and the valve is such that, the valve body having an inlet and the valve comprising a tubular casing covering said inlet, the movable member of the valve is arranged in such a way that the passage of the product constituted by the inlet and the 'envelope can be closed, the valve opening only for a pressure, inside the tank, at least equal to the above predetermined limit.
Avantageusement, l'organe mobile de fermeture du clapet est constitué par une bille ; en variante, cet organe mobile peut être constitué par un pointeau ou tout moyen équivalent.Advantageously, the movable member for closing the valve consists of a ball; alternatively, this movable member can be constituted by a needle or any equivalent means.
De préférence, l'enveloppe tubulaire est fixée sur le corps de valve et comporte un orifice de communication avec l'intérieur du bidon, cet orifice comportant un siège pour l'organe mobile de fermeture, le ressort taré ayant tendance à appliquer cet organe de fermeture contre ce siège.Preferably, the tubular casing is fixed to the valve body and has an orifice for communication with the interior of the container, this orifice comprising a seat for the movable closure member, the calibrated spring tending to apply this closure against this seat.
Avantageusement, la valve selon l'invention comprend une valve standard classique, et l'enveloppe du clapet est rapportée et fixée sur le corps de cette valve classique.Advantageously, the valve according to the invention comprises a conventional standard valve, and the envelope of the valve is attached and fixed to the body of this conventional valve.
Généralement, l'enveloppe du clapet est munie d'un embout de raccordement coaxial à l'orifice de communication pour le branchement d'un tube plongeur.Generally, the cover of the valve is provided with a connection tip coaxial with the communication orifice for the connection of a dip tube.
Une prise de gaz additionnelle, débouchant transversalement, peut être prévue dans ladite enveloppe du clapet, au-delà du siège de la bille, du côté de l'intérieur du bidon.An additional gas outlet, opening transversely, may be provided in said valve casing, beyond the seat of the ball, on the side of the interior of the container.
Lorsque la valve est réalisée à partir d'une valve standard dont le corps comporte un prolongement pour raccordement à un tube plongeur, l'enveloppe du clapet coiffe également ce prolongement et le ressort taré est disposé autour de ce prolongement, coaxialement, de manière à prendre appui contre l'extrémité du corps de valve standard.When the valve is made from a standard valve whose body has an extension for connection to a dip tube, the valve casing also covers this extension and the calibrated spring is arranged around this extension, coaxially, so as to lean against the end of the standard valve body.
De préférence, la pression déterminée, à partir de laquelle s'ouvre le clapet, est de l'ordre de 2. 10⁵ Pa (2 bars).Preferably, the determined pressure, from which the valve opens, is of the order of 2.10⁵ Pa (2 bars).
L'invention est également relative à un bidon aérosol équipé d'une valve telle que définie précédemment.The invention also relates to an aerosol can equipped with a valve as defined above.
L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après à propos d'un exemple de réalisation décrit avec référence aux dessins ci-annexés, mais qui n'est nullement limitatif.The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be more explicitly discussed below in connection with an exemplary embodiment. described with reference to the accompanying drawings, but which is in no way limiting.
La figure 1, de ces dessins, est une coupe axiale, avec parties en extérieur, d'une valve conforme à l'invention, la tige d'actionnement étant en position de fermeture.Figure 1 of these drawings is an axial section, with external parts, of a valve according to the invention, the actuating rod being in the closed position.
La figure 2 montre,semblablement à la figure 1, la valve alors que la tige est en position d'ouverture, la pression dans le bidon étant supérieure à la limite prédéterminée.Figure 2 shows, similarly to Figure 1, the valve while the rod is in the open position, the pressure in the container being greater than the predetermined limit.
La figure 3, enfin, montre la valve, semblablement à la figure 2, alors que la pression dans le bidon est inférieure à la limite prédéterminée.Figure 3, finally, shows the valve, similarly to Figure 2, while the pressure in the container is below the predetermined limit.
En se reportant à la figure 1, on peut voir une valve 1 pour un bidon aérosol (non représenté) contenant un produit liquide sous pression de gaz.Referring to Figure 1, we can see a
La valve 1 comprend un corps 3 fixé sur le bidon par un sertissage 4 propre à emprisonner dans une coupelle 2 prévue sur le bidon, une partie 5, de plus fort diamètre, prévue à l'extrémité supérieure du corps 3.The
Cette partie 5 est en appui contre une rondelle d'étanchéité 6 qui est elle-même en appui contre une collerette 7, de la coupelle 2 dont le plan moyen est orthogonal à l'axe du bidon.This
Le corps 3 cylindrique fait saillie vers l'intérieur du bidon et comprend un mécanisme de valve classique non représenté. Une tige 8 d'actionnement de la valve est monté coulissante dans le corps 3, suivant la direction axiale A. La tige 8 comporte un trou borgne longitudinal 9 s'ouvrant vers le haut, et dans lequel débouche, au voisinage du fond, un canal radial 10 communiquant avec la surface extérieure de la tige 8.The
La tige 8 est rappelée, en position de repos représentée sur la figure 1, par des moyens élastiques (non montrés). Dans cette position, le canal 10 est situé sensiblement à mi-épaisseur de la rondelle 6 et est fermé par la paroi cylindrique interne de cette rondelle.The
Le corps 3 est celui d'une valve standard et comporte un prolongement 11, de diamètre plus faible, muni d'un canal d'entrée 12. Le prolongement 11 est prévu pour un raccordement à un tube plongeur (non représenté) s'étendant vers le fond du bidon.The
Généralement, la commande de l'enfoncement de la tige 8 dans le corps 3 est assurée par action sur un bouton-poussoir (non représenté), de sorte que le canal 10, comme représenté sur la figure 2, débouche dans un volume situé au-dessous de la rondelle d'étanchéité 6.Generally, the control of the insertion of the
Un clapet 13 à organe mobile de fermeture constitué par une bille 14 est prévu à l'intérieur du bidon et est combiné avec la valve standard. Il est clair que l'organe mobile de fermeture du clapet pourrait être constitué par un pointeau, ou autre moyen équivalent. Le clapet 13 comprend une enveloppe 15 fixée sur le corps 3 de manière à coiffer le prolongement 11 et à recouvrir l'entrée 12.A
L'enveloppe 15 comporte un orifice 16 de communication avec l'intérieur du bidon, cet orifice 16 comportant un siège tronconique 17 pour la bille 14. Cette bille est soumise à l'action d'un ressort taré 18. Dans l'exemple représenté sur le dessin, le ressort 18 est un ressort hélicoïdal disposé autour du prolongement 11, coaxialement, de manière à prendre appui contre l'extrémité 19 du corps de valve 3. Le ressort 18 a tendance à appliquer la bille 14 contre le siège 17 et à fermer ainsi l'orifice 16.The
Il est clair que l'expression "ressort taré" doit être comprise dans un sens large et englobe tout moyen élastique taré, agissant comme un ressort, notamment une lame ressort type clinquant.It is clear that the expression “calibrated spring” must be understood in a broad sense and includes any tared elastic means, acting like a spring, in particular a leaf spring type tinsel.
L'enveloppe 15 du clapet est munie d'un embout 20, coaxial à l'orifice 16, pour le branchement d'un tube plongeur non représenté. L'embout 20 comporte un canal 21 dans lequel débouche une prise de gaz additionnelle 22 formée par un passage radial prévu du côté de l'orifice 16 opposé à la bille 14, la prise de gaz additionnelle 22 faisant communiquer le canal 21 et le volume intérieur du bidon.The
Avantageusement, le ressort 18 est taré de manière à maintenir le clapet 14 contre le siège 17 aussi longtemps que la différence de pression entre l'intérieur du bidon et la chambre intérieure de l'enveloppe 15 est inférieure à une valeur de l'ordre de 2 bars.Advantageously, the
Ceci étant, le fonctionnement de la valve selon l'invention est le suivant.However, the operation of the valve according to the invention is as follows.
Au repos, comme illustré sur la figure 1, la tige 8 est en position de fermeture et la bille 14 est en appui contre le siège 17, sous l'action du ressort 18, les pressions à l'intérieur du bidon et de l'enveloppe 15 étant sensiblement les mêmes.At rest, as illustrated in Figure 1, the
Lorsque l'utilisateur actionne la valve et enfonce la tige 8, comme illustré sur la figure 2, l'intérieur de l'enveloppe 15 est mis en communication avec l'atmosphère par le canal 10 et la pression, dans cette enveloppe 15, devient inférieure à la pression gazeuse régnant dans le bidon. Lorsque cette pression gazeuse est suffisante, elle exerce sur la bille 14 une force supérieure à celle du ressort 18 et écarte donc la bille 14 de son siège 17 comme illustré sur la figure 2.When the user actuates the valve and pushes the
Le produit à pulvériser peut alors passer par les canaux 21, l'orifice 16, l'entrée 12, le canal 10 et le trou 9 pour sortir, à travers la buse d'une tête de distribution non représentée, sous forme de gouttelettes pulvérisées dans l'atmosphère.The product to be sprayed can then pass through the
Si la pression dans le bidon est inférieure à la limite établie par le ressort 18, la bille 14 reste appliquée contre le siège 17, malgré l'enfoncement de la tige 8, comme illustré sur la figure 3.If the pressure in the container is less than the limit established by the
Dans ces conditions, même si l'utilisateur enfonce la tige 8, il n'y aura pas de pulvérisation. On évite ainsi de pulvériser dans des conditions de pression insuffisante conduisant à une mauvaise qualité de pulvérisation.Under these conditions, even if the user pushes the
La valve conforme à l'invention permet ainsi de garantir une distribution correcte du produit. Lorsque la pression est devenue trop faible dans le bidon, la distribution ne pourra reprendre qu'après remontée de cette pression à une valeur suffisamment élevée pour provoquer le décollement de la bille 14. Cette remontée de la pression peut être obtenue, dans le cas de bidons rechargeables, par une opération de recharge en gaz propulseur.The valve according to the invention thus makes it possible to guarantee correct distribution of the product. When the pressure has become too low in the container, the distribution can resume only after the pressure has risen to a value high enough to cause the
Cette valve est d'une réalisation simple et économique et peut être obtenue par une modification rapide d'une valve standard classique.This valve is simple and economical to produce and can be obtained by rapid modification of a standard standard valve.
