Description

La présente invention a pour objet une valve doseuse, du type adaptable sur un récipient pressurisé, prévu pour contenir un produit à pulvériser, contenant un gaz propulseur en solution sous pression, et permettant en appuyant sur un bouton de libérer une quantité déterminée de produit. Une valve de ce type est décrite notamment dans le brevet français 1. 287. 373 au nom de Monsieur Lucien Guillou pour "Perfectionnements aux valves doseuses". La valve décrite dans ce brevet est prévue pour fonctionner quand le récipient est en position droite, avec l'ouverture en haut.The present invention relates to a metering valve, of the type adaptable to a pressurized container, intended to contain a product to be sprayed, containing a propellant gas in solution under pressure, and allowing by pressing a button to release a determined quantity of product. A valve of this type is described in particular in French patent 1,287,373 in the name of Mr. Lucien Guillou for "Improvements to metering valves". The valve described in this patent is intended to operate when the container is in an upright position, with the opening at the top.

La présente invention a notamment pour objet une valve du type ci-dessus, fonctionnant en position inversée, et permettant de débiter des doses plus précises, sans variation de la quantité refoulée à chaque expulsion jusqu'à épuisement du flacon, et de permettre aussi un remplissage du flacon dans de meilleures conditions.The subject of the present invention is in particular a valve of the above type, operating in the inverted position, and making it possible to dispense more precise doses, without variation of the quantity delivered on each expulsion until the bottle is exhausted, and also to allow a filling the bottle in better conditions.

Des valves prévues pour le fonctionnement avec le récipient en position inversée sont décrites dans les B US 3. 394. 851 (Gorman) et B FR 2. 403. 833 (Glaxo). Le dispositif du brevet américain est prévu pour un gaz non soluble, tel que l'azote, contrairement à la présente invention. Le ressort de rappel de cette valve est placé vers l'extérieur du récipient, ce qui allonge le trajet de sortie du produit à pulvériser, et impose des dimensions plus grandes à la valve, ce qui limite ses applications. Dans le B FR 2.403. 833, le ressort de rappel de la soupape est situé dans le fond de la valve, et il en résulte que le remplissage de la chambre de mesure peut être gêné.Valves intended for operation with the container in the inverted position are described in B US 3,394,851 (Gorman) and B FR 2,403,833 (Glaxo). The device of the American patent is intended for an insoluble gas, such as nitrogen, contrary to the present invention. The return spring of this valve is placed towards the outside of the container, which lengthens the outlet path of the product to be sprayed, and imposes larger dimensions on the valve, which limits its applications. In B FR 2.403. 833, the valve return spring is located in the bottom of the valve, and as a result the filling of the measuring chamber can be hampered.

L'invention a pour objet une valve du genre en question, dans laquelle le ressort de rappel de la soupape est placé au fond de la valve, mais dans laquelle un remplissage parfait de la chambre de mesure est assuré pendant toute l'utilisation du récipient.The subject of the invention is a valve of the type in question, in which the return spring of the valve is placed at the bottom of the valve, but in which perfect filling of the measuring chamber is ensured during the entire use of the container. .

La description qui va suivre, en regard des dessins annexés, donnée à titre d'exemple non limitatif, fera bien comprendre comment l'invention peut être réalisée.

  • - La figure 1 est une vue en coupe axiale d'une valve selon l'invention suivant la ligne I-I de la figure 2; et
  • - la figure 2 est une vue en coupe perpendiculaire à l'axe de la même valve, suivant la ligne II-II de la figure 1.
The description which follows, with reference to the appended drawings, given by way of nonlimiting example, will make it clear how the invention can be implemented.
  • - Figure 1 is an axial sectional view of a valve according to the invention along line II of Figure 2; and
  • - Figure 2 is a sectional view perpendicular to the axis of the same valve, along line II-II of Figure 1.

La valve selon l'invention, prévue pour être fixée dans l'ouverture d'un récipient tel qu'une bouteille ou analogue, comporte un corps de valve 1 fixé dans une capsule 2 avec interposition d'un joint annulaire 3. La capsule 2 est elle-même sertie sur le col d'un récipient, non représenté, avec interposition d'un autre joint, de façon bien connue. Un tel récipient est prévu pour contenir un produit liquide, avec un gaz sous pression (dit propulseur) soluble dans le produit. Le principe de fonctionnement d'une telle valve doseuse est bien connu. Il est décrit dans les brevets cités ci-dessus. Le corps de valve forme à sa partie supérieure une chambre de mesure 13 et à sa partie inférieure un logement 30 pour un ressort de rappel. Les mots supérieure, inférieure, haut ou bas concernent la position droite du récipient, avec l'ouverture vers le haut. Il est entendu que le récipient doit être renversé pour fonctionner. A l'intérieur du corps de valve est disposée une tige de soupape 4 dont une partie 5 s'étend à l'extérieur, à travers le joint 3. Cette tige comporte un canal axial ou longitudinal 6 débouchant à l'extrémité extérieure de la tige et communiquant avec un passage radial 7. La tige 4 est repoussée vers le haut par un ressort 8 et vient prendre appui contre le joint 3 par un épaulement 9. Dans la position de repos, ressort détendu, avec l'épaulement 9 contre le joint 3, le passage 7 débouche au-dessus du joint (éventuellement dans le joint, mais pas en-dessous) de sorte que le flacon est fermé, et le produit sous pression ne peut sortir. La tige 4 et se prolonge dans l'intérieur du récipient par une partie élargie ou piston 11, par exemple de même diamètre que l'épaulement 9, et un joint annulaire 12 est disposé à une certaine distance du piston, l'ouverture centrale 31 du joint 12 correspondant au diamètre du piston 11. Pour faire sortir une dose du produit, on retourne le récipient, en plaçant l'ouverture avec la valve en bas.The valve according to the invention, intended to be fixed in the opening of a container such as a bottle or the like, comprises a valve body 1 fixed in a capsule 2 with the interposition of an annular seal 3. The capsule 2 is itself crimped onto the neck of a container, not shown, with the interposition of another seal, in a well known manner. Such a container is designed to contain a liquid product, with a pressurized gas (called propellant) soluble in the product. The operating principle of such a metering valve is well known. It is described in the patents cited above. The valve body forms at its upper part a measuring chamber 13 and at its lower part a housing 30 for a return spring. The words upper, lower, upper or lower relate to the right position of the container, with the opening upwards. It is understood that the container must be overturned to function. Inside the valve body is arranged a valve stem 4, a part 5 of which extends outside, through the seal 3. This stem has an axial or longitudinal channel 6 opening out at the outer end of the rod and communicating with a radial passage 7. The rod 4 is pushed upwards by a spring 8 and bears against the seal 3 by a shoulder 9. In the rest position, spring relaxed, with the shoulder 9 against the seal 3, the passage 7 opens above the seal (possibly in the seal, but not below) so that the bottle is closed, and the product under pressure cannot exit. The rod 4 and extends into the interior of the container by an enlarged part or piston 11, for example of the same diameter as the shoulder 9, and an annular seal 12 is disposed at a certain distance from the piston, the central opening 31 of the seal 12 corresponding to the diameter of the piston 11. To release a dose of the product, the container is turned over, placing the opening with the valve at the bottom.

Quand on enfonce la tige 4 contre la force du ressort 8, au moyen d'un bouton poussoir non représenté, le piston 11 vient obturer l'ouverture du joint 12 avant que l'ouverture du passage 7 n'apparaisse sur la face inférieure du joint 3. On forme ainsi un volume fermé, ou chambre 13, qui contient une dose, dont le volume est déterminé de façon précise, du produit à pulvériser chargé de gaz propulseur dissout sous pression. Quand on continue à enfoncer la tige 4 contre la force du ressort 8, l'ouverture du passage 7 apparaît dans la chambre 13, et le contenu de celle-ci est alors évacué par le passage 7 et le canal 6, sous l'effet du gaz propulseur qui se dégage par suite de la chute de la pression. Après avoir fait sortir une dose, on libère la tige 4 qui est renvoyée à sa position initiale par le ressort de rappel 8. La chambre 13 est alors ouverte. Pour recharger la chambre de dosage, il faut tenir le récipient renversé.When the rod 4 is pressed against the force of the spring 8, by means of a push button not shown, the piston 11 closes the opening of the seal 12 before the opening of the passage 7 appears on the underside of the joint 3. A closed volume, or chamber 13, is thus formed which contains a dose, the volume of which is precisely determined, of the product to be sprayed loaded with propellant dissolved under pressure. When one continues to push the rod 4 against the force of the spring 8, the opening of the passage 7 appears in the chamber 13, and the content thereof is then evacuated by the passage 7 and the channel 6, under the effect propellant which is released as a result of the drop in pressure. After having released a dose, the rod 4 is released which is returned to its initial position by the return spring 8. The chamber 13 is then opened. To reload the dosing chamber, keep the container upside down.

Comme dans le brevet français 1. 287. 373 mentionné ci-dessus, le produit par vient dans la chambre 13 par au moins une ouverture prévue dans le bas du corps de valve, en-dessous du joint 12. Au-delà du piston 11, la tige 4 se prolonge avantageusement par une partie amincie 14 présentant par exemple un épaulement 15 pour l'appui du ressort. La tige 4 se termine par un fùt 16 engagé entre les spires du ressort et servant au guidage et au centrage de la tige 4. La partie amincie 14 a des dimensions telles qu'en position de repos, le piston 11 étant dégagé du joint 12, le produit puisse parvenir facilement dans la chambre 13.As in French patent 1,287,373 mentioned above, the product comes into the chamber 13 through at least one opening provided in the bottom of the valve body, below the seal 12. Beyond the piston 11 , the rod 4 is advantageously extended by a thinned part 14 having for example a shoulder 15 for the support of the spring. The rod 4 ends with a drum 16 engaged between the turns of the spring and serving for guiding and centering the rod 4. The thinned part 14 has dimensions such as in rest position, the piston 11 being released from the seal 12, the product can easily reach the chamber 13.

Conformément à une caractéristique de la présente invention, la partie amincie 14 est constituée de plusieurs nervures radiales 17a, 17b, 17c, 17d, etc, de section constante ou non et s'étendant depuis le piston 11 jusqu'à l'épaulement 15. Avantageusement, chaque nervure a la forme bien visible sur la figure 1. Cette disposition présente l'avantage de laisser une passage important pour le produit tant lors du remplissage initial du flacon que lors de l'emploi normal. Les nervures 17 maintiennent en outre l'ouverture du joint si celui- ci venait à glonfler sous l'influence du produit mis en circulation. En combinaison avec cette forme de la tige, le bas du corps de valve forme un logement 30 pour le ressort, et ce logement comporte des ouvertures 19 s'étendant sur toute la hauteur disponible, c'est-à-dire depuis un point voisin du joint 12, en dessous de celui- ci, pratiquement jusqu'au fond du logement 30 du ressort, le nombre des ouvertures 19 étant différent du nombre des nervures 17, de façon à avoir toujours au moins un passage continu dégagé, en évitant qu'il y ait une nervure en face de chaque ouverture.In accordance with a characteristic of the present invention, the thinned part 14 consists of several radial ribs 17a, 17b, 17c, 17d, etc., of constant section or not and extending from the piston 11 to the shoulder 15. Advantageously, each rib has the shape clearly visible in FIG. 1. This arrangement has the advantage of leaving a large passage for the product both during the initial filling of the bottle and during normal use. The ribs 17 also maintain the opening of the seal if it were to swell under the influence of the product put into circulation. In combination with this shape of the stem, the bottom of the valve body forms a housing 30 for the spring, and this housing has openings 19 extending over the entire available height, that is to say from a neighboring point. of the seal 12, below it, practically to the bottom of the spring housing 30, the number of openings 19 being different from the number of ribs 17, so as to always have at least one continuous clear passage, avoiding that 'there is a rib opposite each opening.

Avantageusement, il y a quatre nervures 17 et trois ouvertures 19, séparées par des parois 20 réunies par un fond 21.Advantageously, there are four ribs 17 and three openings 19, separated by walls 20 joined by a bottom 21.

Selon une autre caractéristique de la présente invention, la tige de soupape 4 est en deux pièces : une première pièce supérieure 32 constituée par la partie extérieure 5 et le piston 11, et une deuxième pièce 33 constituée par la partie amincie 14, l'épaulement 15 et le fùt 16. Les deux pièces ainsi constituées sont plus faciles à fabriquer, avec plus de précision, en évitant le moulage en coquille. Les deux pièces peuvent être assemblées par tout moyen : emboite- ment à force, avec ou sans colle (comme indiqué par la ligne pointillée 29), vissage, soudure, etc.According to another characteristic of the present invention, the valve stem 4 is in two parts: a first upper part 32 constituted by the external part 5 and the piston 11, and a second part 33 constituted by the thinned part 14, the shoulder 15 and the barrel 16. The two parts thus formed are easier to manufacture, with greater precision, avoiding shell molding. The two parts can be assembled by any means: push-fit, with or without glue (as indicated by the line dotted line 29), screwing, welding, etc.

Afin de maintenir le joint 12 dans son logement, on peut prévoir une pièce d'écartement 23 (moitié droite de la figure 1), prenant appui d'un côté sur le joint 3, de l'autre sur le joint 12 et sur un épaulement 24 du corps de valve 1, ce qui limite le serrage du joint 12.In order to keep the seal 12 in its housing, it is possible to provide a spacer 23 (right half of FIG. 1), bearing on one side on the seal 3, on the other on the seal 12 and on a shoulder 24 of the valve body 1, which limits the tightening of the seal 12.

Pour empêcher les joints de glisser lors du remplissage, on prévoit des pointes 25, sur le corps de valve 1 et/ou sur la pièce d'écartement 23.To prevent the seals from sliding during filling, spikes 25 are provided on the valve body 1 and / or on the spacer 23.

En l'absence de la pièce d'écartement 23, le corps de valve 1 peut présenter des nervures radiales 26 (moitié gauche de la figure 1) qui renforcent mécaniquement la chambre, surtout quand elle est très creuse, pour expulser des grandes doses. Les nervures servent également à maintenir en place le joint 12. En supprimant la déformation de la chambre, la présence des nervures permet d'avoir des doses plus précises.In the absence of the spacer 23, the valve body 1 may have radial ribs 26 (left half of Figure 1) which mechanically strengthen the chamber, especially when it is very hollow, to expel large doses. The ribs also serve to hold the seal 12 in place. By eliminating the deformation of the chamber, the presence of the ribs makes it possible to have more precise doses.

Il va de soi que le mode de réalisation décrit n'est qu'un exemple et qu'il serait possible de le modifier, notamment par substitution d'équivalents techniques, sans sortir pour cela du cadre de l'invention.It goes without saying that the embodiment described is only an example and that it would be possible to modify it, in particular by substitution of technical equivalents, without departing from the scope of the invention.
