Abstract
Description
La présente invention a pour objet un gicleur pour vaporisateur du type valve pour aérosols. The present invention relates to a spray nozzle for the valve type for aerosols.
Les vaporisateurs peuvent être utilisés pour atomiser deux sortes de produits liquides : les liquides qui ne contiennent pratiquement aucun gaz en solution, le liquide étant expulsé soit par un pompage, soit par un gaz propulseur non dissout (azote), et les liquides qui contiennent un gaz propulseur dissout (fréon). Dans ce dernier cas, la libération du liquide à l'air provoque la vaporisation instantanée du propulseur et son expansion violente, ce qui divise très finement le liquide et élargit le jet. Vaporizers can be used to atomize two kinds of liquid products: liquids which contain practically no gas in solution, the liquid being expelled either by a pumping, or by an undissolved propellant gas (nitrogen), and liquids which contain a dissolved propellant (freon). In the latter case, the release of the liquid to the air causes the instantaneous vaporization of the propellant and its violent expansion, which very finely divides the liquid and widens the jet.
Dans tous les cas, on utilise des petits gicleurs, généralement en matière plastique moulée, qui présentent un orifice central axial, auquel le liquide à atomiser est amené par des canaux dont lorfentatlon est définie pour donner au liquide un mouvement rotatif ou tourbillonnaire. Ces canaux, et cet orifice ont des dimensions très faibles, de l'ordre de un à quelques dixièmes de millimètres. Après usage, les canaux et l'orifice restent mouillés par le liquide.Certains liquides, en séchant, peuvent former des dépôts qui occluent les canaux et/ou orifice déjection. Pour éviter cet inconvénient, la présente invention a pour objet un gicleur à obturation, dont l'orifice central d'éjection est obturé au repos, a la manière d'un injecteur de moteur à combustion interne. Le produit subsistant dans les canaux du gicleur ne sèche pas; il ne se produit pas d'occlusion. In all cases, small nozzles are used, generally made of molded plastic, which have an axial central orifice, to which the liquid to be atomized is supplied by channels whose lorfentatlon is defined to give the liquid a rotary or swirling movement. These channels and this orifice have very small dimensions, of the order of one to a few tenths of a millimeter. After use, the channels and the orifice remain wet with the liquid. Some liquids, as they dry, can form deposits which occlude the channels and / or orifice. To avoid this drawback, the subject of the present invention is a shut-off nozzle, the central ejection orifice of which is closed at rest, in the manner of an internal combustion engine injector. The product remaining in the nozzle channels does not dry; there is no occlusion.
Un tel gicleur doit avolr un prix de revient extrêmement faible, du fait qu'il est destiné à être jeté quand le flacon sur lequel il est monté est vidé. Rappelons que les dimensions d'un tel gicleur sont très réduites : quelques millimètres. Il y a donc des conditions difficiles à satisfaire. Such a nozzle must avolr an extremely low cost price, because it is intended to be discarded when the bottle on which it is mounted is emptied. Remember that the dimensions of such a nozzle are very small: a few millimeters. So there are difficult conditions to meet.
Conformément à l'invention, un dispositif de gicleur pour système aérosol comportant un orifice central axial d'éjection à travers une paroi ayant une face extérieure et une face intérieure, et des canaux, disposés autour de l'orifice contre la surface intérieure de ladite paroi, orientés pour communiquer au liquide à atomiser un mouvement rotatif ou tourbillonnaire, est remarquable notamment en ce qu'il comporte un pointeau disposé contre la face intérieure de ladite paroi, le pointeau étant conformé pour obturer ou dégager ledit orifice, et étant rappelé élastiquement en position de repos de fermeture, la force élastique de rappel du pointeau étant produite par déformation d'un élément en matière plastique. According to the invention, a spray device for aerosol system comprising a central axial orifice for ejection through a wall having an outer face and an inner face, and channels, arranged around the orifice against the inner surface of said wall, oriented to communicate to the liquid to be atomized a rotary or swirling movement, is remarkable in particular in that it comprises a needle disposed against the inner face of said wall, the needle being shaped to close or release said orifice, and being biased elastically in the closed rest position, the elastic force for returning the needle being produced by deformation of a plastic element.
Selon l'invention, le pointeau est connecté à une partie solidaire de la paroi comportant l'orifice d'éjection, par une liaison de glissement étanche. According to the invention, the needle is connected to an integral part of the wall comprising the ejection orifice, by a sealed sliding link.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, donnée à titre d'exemple non limitatif, en regard des dessins ci-joints, et qui fera bien comprendre comrnent l'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 drawings, and which will make it clear how the invention can be carried out.

Sur la figure 1, le gicleur 1 de forme générale cylindrique est logé dans une cavité de forme cylindrique correspondante, formée dans le bouton poussoir 2 d'un système aérosol. Il a un diamètre de quelques millimètres, par exemple cinq millimètres, et une longueur du même ordre, ou un peu plus grande. Le gicleur a une extrémité extérieure 122 et une extrémité intérieure 13. Il est avantageusement maintenu en place, par exemple par enclsquetage d'une nervure périphérique 11 prévue autour du gicleur, dans une rainure 21 de forme appropriée, prévue dans la paroi cylindrique de la cavité du bouton poussoir.Le gicleur I est constitué d'un capot 12, ayant une paroi cylindrique 121 et une paroi d'extrémité extérieure, éventuellement en saillie, plane ou non, formee par un fond 122 perce d'un orifice central axial 123. Contre la face interne du fond 122 sont prévues des aubes directrices 124 délimitant des canaux, pour communiquer de façon connue au liquide à expulser, un mouvement rotatif ou tourbillonnaire, autour de l'axe de l'orifice 123. Le capot 12 est fermé vers l'intérieur par un bouchon 13. In FIG. 1, the nozzle 1 of generally cylindrical shape is housed in a cavity of corresponding cylindrical shape, formed in the push button 2 of an aerosol system. It has a diameter of a few millimeters, for example five millimeters, and a length of the same order, or a little greater. The nozzle has an outer end 122 and an inner end 13. It is advantageously held in place, for example by fitting a peripheral rib 11 provided around the nozzle, in a groove 21 of suitable shape, provided in the cylindrical wall of the cavity of the push button. The nozzle I consists of a cover 12, having a cylindrical wall 121 and an external end wall, possibly projecting, flat or not, formed by a bottom 122 pierced with an axial central orifice 123 Against the internal face of the bottom 122 are provided guide vanes 124 delimiting channels, to communicate in a known manner to the liquid to be expelled, a rotary or swirling movement, around the axis of the orifice 123. The cover 12 is closed inward by a plug 13.
Ce bouchon peut être maintenu en place simplement par le capot 12 luimême calé par lenclîquetage 11, 21 ou peut être fixé au capot par collage, soudure haute fréquence ou tout autre moyen. En variante, ce bouchon peut faire partie intégrante du bouton poussoir, moule en une seule pièce avec lui.This plug can be held in place simply by the cover 12 itself wedged by latching 11, 21 or can be fixed to the cover by gluing, high frequency welding or any other means. Alternatively, this plug can be an integral part of the push button, mold in one piece with it.
A l'intérieur du capot 12 est disposé un pointeau 14 mobile et sollicité élastiquement vers l'extérieur de façon à obturer l'orifice 123 quand il est en position de repos, en butée contre le bord interne de l'orifice 123. La création de la force elastique sollicitant le pointeau vers sa position de repos, d'une façon économiquement industrielle et fiable dans les dimensions usuelles pour un tel gicleur, est réalisée de la façon suivante, conformément à la présente Invention. Inside the cover 12 is disposed a movable needle 14 and resiliently biased towards the outside so as to close the orifice 123 when it is in the rest position, abutting against the internal edge of the orifice 123. The creation elastic force urging the needle towards its rest position, in an economically industrial and reliable manner in the usual dimensions for such a nozzle, is produced in the following manner, in accordance with the present invention.
Le pointeau est formé avec une partie conique 141 opposée à la pointe du pointeau, et la pointe de ce cone est engagée dans un cylindre souple T31 solidaire du bouchon 13, et par conséquent, solidaire du capot 12. Pour obtenir la souplesse désirée, le cylindre peut comporter des fentes axiales, ou être constitué par un certain nombre de dolgts, trois ou quatre par exemple
Afin de permettre le décollement du pointeau sous l'effet de la pression du liquide à expulser, le pointeau comporte une jupe 142 munie sur son bord intérieur d'une lèvre d'étanchéité 143 glissant le long de la paroi d'un prolongement cylindrique 132 du bouchon 13.Cette liaison de glissement étanche, et résistante mécaniquement, assure l'absence de pression entre le pointeau et le bouchon, donc le décollement du pointeau lors de la montée de la pression arrivant par le canal 3.The needle is formed with a conical part 141 opposite the point of the needle, and the point of this cone is engaged in a flexible cylinder T31 secured to the plug 13, and therefore secured to the cover 12. To obtain the desired flexibility, the cylinder can have axial slots, or be made up of a certain number of dolgts, three or four for example
To allow separation of the needle under the effect of the pressure of the liquid to be expelled, the needle has a skirt 142 provided on its inner edge with a sealing lip 143 sliding along the wall of a cylindrical extension 132 of the plug 13.This tight, mechanically resistant sliding connection ensures the absence of pressure between the needle and the plug, therefore the separation of the needle during the rise in pressure arriving through the channel 3.
Le bouchon 13 est percé d'un canal 3 pour le passage du liquide à expulser, en communication avec le canal 4 formé dans le bouton poussoir, par l'intermédiaire d'une cavité 135 formée dans le bouchon
13.The plug 13 is pierced with a channel 3 for the passage of the liquid to be expelled, in communication with the channel 4 formed in the push button, by means of a cavity 135 formed in the plug
13.
Le pointeau 14 peut avoir la forme pointue représentée sur la figure 1, ou en variante, une forme de bouchon 145 comme représenté sur la vue de détail de la figure 2. The needle 14 may have the pointed shape shown in FIG. 1, or alternatively, a plug shape 145 as shown in the detail view of FIG. 2.
il est facile de concevolr que le cône pourrait être porté par le bouchon 13, et le cylindre souple par le pointeau 14. Pour améliorer le guidage du pointeau, le cône 141 peut comporter, comme représenté en pointillé, un prolongement 146 s'engageant dans une cavité 133 formée dans le bouchon 13. it is easy to conceive that the cone could be carried by the plug 13, and the flexible cylinder by the needle 14. To improve the guiding of the needle, the cone 141 may include, as shown in dotted lines, an extension 146 engaging in a cavity 133 formed in the plug 13.
La figure 3 est une vue en copue axiale d'un autre mode de réalisation de l'invention. Dans cet exemple, le gicleur est formé directement dans la paroi du bouton poussoir. Celui-ci est constitué par un embout nasal 50, comportant un fût allongé 51, percé à son extrémité supérieure d'un orifice d'éjection 52 et muni à l'autre extrémité de deux ailes d'actionnement 53a, 53b. A l'intérieur du fût 51, est logé un gicleur allongé 54, qui laisse dégagé un passage 55 (dans cet exemple, un canal central) s'étendant depuls !'extrémité inférieure du gicleur,
Jusqu'à son extrémité supérieure, où 11 débouche, par un passage de sortie latérale 56, dans une chambre de turbulence 57. A l'intérieur de cette chambre, au voisinage de l'orifice 52, sont prévues des aubes directrices 58 servant à communiquer au fluide expulsé un mouvement rotatif ou toubillonnaire.Dans la chambre 57, est logé un pointeau 60, entre l'orifice 52 et l'extrémité supérieure du gicleur 54. Comme on peut le voir sur le dessin (figure 4), le pointeau 60 comporte un pointe 61, engagée élastiquement dans l'orifice 52, et opposée à cette pointe, un bossage conique 62 engagé élastiquement entre plusieurs doigts 63 faisant saillie à la partie supérieure du gicleur 54. Les doigts sont assez minces pour présenter une souplesse permettant d'assurer un effort élastique permanent sur le bossage 62. Le pointeau comporte également une jupe 64 formée avec une lèvre d'étanchéité 65, prévue pour glisser avec étanchéité, sur.un appendice cylindrique 66, comme dans l'exemple précédent.Figure 3 is an axial view of another embodiment of the invention. In this example, the nozzle is formed directly in the wall of the push button. This consists of a nose piece 50, comprising an elongated barrel 51, pierced at its upper end with an ejection orifice 52 and provided at the other end with two actuating wings 53a, 53b. Inside the barrel 51 is housed an elongated nozzle 54, which leaves a passage 55 (in this example, a central channel) extending from the bottom end of the nozzle,
Up to its upper end, where 11 opens, by a lateral outlet passage 56, into a turbulence chamber 57. Inside this chamber, in the vicinity of the orifice 52, are provided guide vanes 58 serving to communicate to the expelled fluid a rotary or swirling movement. In the chamber 57, is housed a needle 60, between the orifice 52 and the upper end of the nozzle 54. As can be seen in the drawing (FIG. 4), the needle 60 comprises a point 61, engaged elastically in the orifice 52, and opposite this point, a conical boss 62 engaged elastically between several fingers 63 projecting from the upper part of the nozzle 54. The fingers are thin enough to present flexibility allowing to ensure a permanent elastic force on the boss 62. The needle also includes a skirt 64 formed with a sealing lip 65, designed to slide with sealing, sur.un cylindrical appendage 66, as in the previous example.
L'extrémité inférieure du gicleur allongé 55 est limitée par une section plane 68. La longueur du gicleur est prévue pour que, une fois enfoncé à fond, et calé par l'épaulement 69, la surface plane 68 se trouve coplanaire avec la surface 71 du fond du poussoir, adapté à venir couvrir la soupape 72 d'un vaporisateur, ce qui assure le calage du gicleur 54 dans le poussoir allongé 50. The lower end of the elongated nozzle 55 is limited by a planar section 68. The length of the nozzle is provided so that, once fully depressed and wedged by the shoulder 69, the planar surface 68 is coplanar with the surface 71 from the bottom of the pusher, adapted to cover the valve 72 with a spray bottle, which ensures the setting of the nozzle 54 in the elongated pusher 50.
