Description

Dispositif d'obturation de buse de distribution de fluide
La présente invention a pour objet un dispositif d'obturation de buse de distribution de fluide et autres appareils de vaporisation ou d'expulsion de fluides divers, liquides ou pâteux, et s'applique plus particulièrement aux appareils manuels.
Fluid distribution nozzle closure device
The present invention relates to a device for closing off a fluid distribution nozzle and other devices for spraying or expelling various fluids, liquid or pasty, and applies more particularly to manual devices.

L'invention concerne aussi bien les appareils fonctionnant sous l'effet d'un fluide propulseur sous pression contenu dans le récipient du vaporisateur (flacon, bombe, etc.) que les appareils du type pompe actionnés par un doigt.The invention relates both to devices operating under the effect of a propellant fluid under pressure contained in the vaporizer container (bottle, bomb, etc.) as devices of the pump type actuated by a finger.

Ces divers appareils comportent une soupape de sortie dont l'ouverture permet le débit d'expulsion du fluide, qui se déplace dans un canal jusqu'à une buse de sortie, ou un gicleur. Après l'expulsion, le canal compris entre la soupape de sortie et le gicleur reste généralement rempli de fluide. Ce fluide est exposé à l'air par le gicleur et peut être pollué. II peut aussi durcir et obstruer la sortie. Pour éviter ces inconvénients, on a déjà proposé divers types de systèmes obturant la sortie du gicleur. Jusqu'à présent, aucun n'a donné vraiment satisfaction. La présente invention a pour but un dispositif d'obturation de buse de distribution de fluide qui soit efficace, fiable, d'un prix de revient acceptable, tant à fabriquer qu'à monter en place. Ce e résultat est obtenu par la présente invention, qui a pour objet un dispositif d'obturation de buse de distribution de fluide destiné à être placé dans une cavité à l'extrémité d'un canal de sortie dans un bouton poussoir de commande, caractérisé en ce qu'il comporte un obturateur en mafière déformable, ayant une forme cylindrique munie à une extrémité d'un fond avec une- ouverture centrale, et un pointeau creux rigide formé d'une jupe cylindrique avec une pointe à une extrémité, disposé à l'intérieur dudit manchon, de façon que la pointe obture ladite ouverture centrale, et comportant des passages ménagés dans sa paroi, au voisinage de la pointe, le fluide arrivant par la cavité intérieure du pointeau, traversant lesdits passages et venant en contact avec l'intérieur dudit obturateur et le déformant sous l'effet de la pression, libérant ainsi le passage entre pointeau et obturateur. These various devices include an outlet valve whose opening allows the expulsion flow of the fluid, which moves in a channel to an outlet nozzle, or a nozzle. After expulsion, the channel between the outlet valve and the nozzle generally remains filled with fluid. This fluid is exposed to air by the nozzle and can be polluted. It can also harden and obstruct the outlet. To avoid these drawbacks, various types of systems have already been proposed closing the outlet of the nozzle. So far, none have been very successful. The object of the present invention is a device for closing off a fluid distribution nozzle which is efficient, reliable, at an acceptable cost price, both to manufacture and to assemble in place. This result is obtained by the present invention, which relates to a device for closing off a fluid distribution nozzle intended to be placed in a cavity at the end of an outlet channel in a control push button, characterized in that it comprises a shutter made of deformable material, having a cylindrical shape provided at one end with a bottom with a central opening, and a rigid hollow needle formed by a cylindrical skirt with a point at one end, disposed at the interior of said sleeve, so that the point closes off said central opening, and having passages formed in its wall, in the vicinity of the point, the fluid arriving through the interior cavity of the needle, passing through said passages and coming into contact with the interior of said shutter and deforming it under the effect of pressure, thus freeing the passage between needle and shutter.

D'autres caractéristiques et avantages de l'invention apparaitront au cours de la description qui va suivre, donnée à titre d'exemple non limitatif, en regard du dessin ci-joint, et qui fera bien comprendre comment Invention peut être réalisée. Other characteristics and advantages of the invention will appear during the description which follows, given by way of nonlimiting example, with reference to the attached drawing, and which will make it clear how the invention can be implemented.

La figure unique est une vue en coupe axiale d'un dispositif selon l'invention, qui est essentiellement de révolution. The single figure is an axial sectional view of a device according to the invention, which is essentially of revolution.

Le dispositif selon l'invention tel que représenté sur la figure unique est constitué de deux parties: un pointeau rigide creux 1, et un obturateur déformable 2. Les deux pièces sont de révolution : ce qui facilite le montage, c'est-à-dire la mise en place d'une pièce sur l'autre et la mise en place du dispositif dans la cavité 3 prévue à cet effet dans un bouton poussoir 4. Cependant, cette condition n'est pas théoriquement indispensable. Un canal de sortie 5 débouche dans la cavité 3. Le pointeau comprend essentiellement trois parties décrites du haut en bas sur la figure: une pointe 11 de forme préférentielle conique, avec une partie cylindrique 1 la ; une partie ajourée 12 et une jupe inférieure 13. La partie ajourée a pour fonction de réunir la pointe et la jupe inférieure tout en permettant le passage d'un fluide de l'intérieur vers l'extérieur du pointeau. Cette partie 12 peut être constituée de plusieurs nervures radiales. The device according to the invention as shown in the single figure consists of two parts: a hollow rigid needle 1, and a deformable shutter 2. The two parts are of revolution: which facilitates assembly, that is to say say the establishment of a part on the other and the establishment of the device in the cavity 3 provided for this purpose in a push button 4. However, this condition is not theoretically essential. An outlet channel 5 opens into the cavity 3. The needle essentially comprises three parts described from top to bottom in the figure: a tip 11 of preferential conical shape, with a cylindrical part 11a; an openwork part 12 and a lower skirt 13. The openwork part has the function of joining the point and the lower skirt while allowing the passage of a fluid from the inside to the outside of the needle. This part 12 can consist of several radial ribs.

La partie inférieure 13 est prévue pour obtenir une jonction étanche avec l'obturateur 2 et avec la paroi du bouton poussoir 4, de façon que tout le fluide expulsé par le canal S parvienne dans la cavité 3 et de là passe à travers la partie ajourée 12 du pointeau. Pour obtenir ce résultat conformément à une disposition avantageuse de la présente invention, la jupe inférieure 13 est prolongée par une partie 14 rabattue vers la pointe. Ce rabat 14 délimite avec la jupe 13 une feuillure 15 dans laquelle une partie de l'obturateur déformable 2 peut être serrée élastiquement, pour assurer la fixation de cet obturateur sur le pointeau, et l'étanchéité entre l'obturateur et le pointeau. Enfin pour obtenir la fixation du pointeau sur le bouton poussoir, en plus du serrage élastique entre la paroi du rabat 14 et celle du bouton poussoir, serrage qui assure l'étanchéité, il est prévu, de façon classique, un talon 15 au voisinage de l'extrémité du pointeau. The lower part 13 is provided to obtain a tight junction with the shutter 2 and with the wall of the push button 4, so that all the fluid expelled through the channel S reaches the cavity 3 and from there passes through the perforated part. 12 of the needle. To obtain this result in accordance with an advantageous arrangement of the present invention, the lower skirt 13 is extended by a portion 14 folded towards the point. This flap 14 defines with the skirt 13 a rebate 15 in which part of the deformable shutter 2 can be tightened elastically, to ensure the fixing of this shutter on the needle, and the seal between the shutter and the needle. Finally, in order to obtain the fixing of the needle on the push button, in addition to the elastic tightening between the wall of the flap 14 and that of the push button, tightening which ensures the tightness, a heel 15 is provided in the conventional manner in the vicinity the end of the needle.

L'obturateur 2 comporte une partie cylindrique 21 dont la base est prévue pour être engagée avec serrage dans la feuillure 15. Un biseautage peut être prévu pour faciliter l'introduction. The shutter 2 comprises a cylindrical part 21, the base of which is intended to be engaged with clamping in the rebate 15. A bevel can be provided to facilitate introduction.

Ce serrage est renforcé par l'enfoncement du pointeau dans la cavité 3 du bouton poussoir. L'extrémité supérieure de l'obturateur est formée avec un fond 22 ayant une ouverture centrale 23 coopérant avec la pointe il du pointeau. L'obturateur 2 est déformable. Il est fait en un matériau souple, et à l'état de repos, le bord de l'ouverture 23 est appliqué élastiquement contre la surface conique de la pointe 11. Afin d'améliorer la souplesse, le raccordement du fond 22 avec le cylindre 21 peut comporter des plis 24. This tightening is reinforced by the insertion of the needle into the cavity 3 of the push button. The upper end of the shutter is formed with a bottom 22 having a central opening 23 cooperating with the tip of the needle. The shutter 2 is deformable. It is made of a flexible material, and in the state of rest, the edge of the opening 23 is applied elastically against the conical surface of the tip 11. In order to improve flexibility, the connection of the bottom 22 with the cylinder 21 may include folds 24.

Quand un fluide sous pression est libéré, ou chassé dans le canal 5, il pénètre à l'intérieur du pointeau, traverse les ouvertures ménagées dans la paroi ajourée 12, vient en contact avec l'obturateur et le déforme sous l'effet de la pression, qui peut être légère, ce qui libère le passage entre pointeau et obturateur ; le produit est alors distribué à l'extérieur de Fobturateur. En fin de distribution, le jet de produit est coupé par l'obturateur. Le dispositif selon l'invention est simple, et d'encombrement réduit: il peut être monté en lieu et place des embouts existants. Il requiert seulement une pression interne d'ouverture réduite, ne nécessitant aucune modification dans les mécanismes de distribution. On remarquera encore que le dispositif de l'invention peut permettre de se passer du clapet haut dans les mécanismes à pompe et améliorer l'amorçage de tels mécanismes.  When a pressurized fluid is released, or expelled in the channel 5, it penetrates inside the needle, crosses the openings made in the perforated wall 12, comes into contact with the shutter and deforms it under the effect of the pressure, which can be slight, which frees the passage between needle and shutter; the product is then distributed outside the shutter. At the end of dispensing, the product jet is cut by the shutter. The device according to the invention is simple, and of reduced size: it can be mounted in place of existing end pieces. It only requires a reduced internal opening pressure, requiring no modification in the dispensing mechanisms. It will also be noted that the device of the invention can make it possible to dispense with the high valve in the pump mechanisms and improve the priming of such mechanisms.
