Abstract

Valve substantially comprised of a rigid cup (1) and a flexible and elastic shutter (2) comprising two valves (6, 14) co-operating with seats (7, 22) formed by the cup. When filling the container by pressure injection of product through the valve, the shutter (2) is extended and the two valves (6, 14) are opened whereas, during the dispensing, by limited extension of the shutter under the effect of a manual pressure exerted on a tail pusher-diffuser (11) inserted in the shutter, only the first valve (6) is opened ensuring a communication between a product-supplying plunger tube (23) carried by the shutter (2) and the outlet (5) of the valve. An additional gas tap (19) may be pierced into the second valve (14).

Description

La présente invention concerne l'industrie du conditionnement sous pression. Elle vise plus particulièrement une valve comportant un nombre réduit de constituants. La recherche d'un abaissement du coût des valves a conduit à la conception de valves dépourvues de ressorts de rappel et utilisant l'élasticité d'un obturateur pour combiner les fonctions d'obturation et de clapets.The present invention relates to the pressure packaging industry. It relates more particularly to a valve comprising a reduced number of constituents. The search for a lowering of the cost of the valves has led to the design of valves devoid of return springs and using the elasticity of a shutter to combine the functions of shutter and valves.

On trouve des descriptions de telles valves notamment dans EP-A-80 750 les brevets des Etats-Unis d'Amérique Nos. 2 913 749 et 3 282 474, ainsi que dans le brevet de la République Fédérale d'Allemagne No. 2 249 891.Descriptions of such valves are found in particular in EP-A-80,750 to the United States patents Nos. 2,913,749 and 3,282,474, as well as in Federal Republic of Germany Patent No. 2,249,891.

L'invention a pour but une valve de ce type présentant de nombreux avantages sur les valves classiques. Outre ses qualités de fonctionnement et de fiabilité, elle fonctionne lorsque le récipient est tenu verticalement de la façon habituelle, tandis que la plupart des valves de ce type classiques ne fonctionnent qu'avec le récipient retourné. De plus, la valve suivant l'invention permet l'admission de gaz additionnel dans le produit distribué.The object of the invention is to provide a valve of this type having numerous advantages over conventional valves. In addition to its qualities of operation and reliability, it works when the container is held vertically in the usual way, while most of the valves of this conventional type only work with the container turned upside down. In addition, the valve according to the invention allows the admission of additional gas into the dispensed product.

L'invention a pour objet une valve simplifiée, pour la distribution de produits fluides conditionnés dans un récipient sous pression, comprenant une coupelle en matériau rigide, de fixation étanche sur le col du récipient, et un obturateur à clapet en matériau souple et élastique, logé dans une cheminée axiale tubulaire ouverte de la coupelle, l'obturateur étant creusé d'un premier canal axial tubulaire borgne débouchant à l'extérieur par un orifice entouré d'un rebord tubulaire, de fixation étanche de l'obturateur sur l'extrémité de la cheminée extérieure au récipient, l'obturateur présentant, au voisinage du fond borgne du premier canal, un élargissement annulaire diamétral extérieur formant un premier clapet coopérant par l'élasticité de l'obturateur avec un siège formé par l'extrémité de la cheminée vers l'extérieur du récipient, la paroi latérale de l'obturateur étant percée d'au moins un passage radial reliant l'intérieur du premier canal à un premier espace délimité entre la paroi interne de la cheminée et la paroi externe de l'obturateur comprise entre le rebord et le premier clapet, le premier canal recevant, de façon étanche extérieurement, l'extrémité d'une buse de remplissage du récipient en produit injecté sous pression à travers la valve, par allongement axial de l'obturateur à partir du rebord, et décollement du premier clapet de son siège sous l'effet de la pression du fluide injecté par la buse, et, alternativement la queue tubulaire d'un poussoir-diffuseur, pour la distribution à volonté du produit conditionné, par allongement axial limité de l'obturateur, sous l'effet d'une pression manuelle exercée par l'utilisateur sur le poussoir diffuseur l'obturateur présentant un prolongement axial vers l'intérieur du récipient, creusé d'un second canal axial borgne débouchant à l'intérieur du récipient et recevant l'extrémité d'un tube d'amenée du produit à distribuer plongeant jusqu'au fond du récipient voit (EP-A-80 750). La valve est caractérisée en de que le prolongement présente une collerette annulaire extérieure formant un second clapet coopérant par l'élasticité de l'obturateur avec un siège formé par la paroi interne de la coupelle au voisinage de la cheminée, clapet qui s'ouvre élastiquement sous l'effet de la pression du fluide injecté lors du remplissage, mais qui reste fermé, en appui élastique sur son siège lors de la distribution du produit, le second canal d'amenée du produit à distribuer débouchant, par au moins un passage radial, dans un second espace délimité entre la paroi interne de la coupelle et la paroi externe de l'obturateur comprise entre le premier clapet et le second clapet.The subject of the invention is a simplified valve for dispensing fluid products packaged in a pressure container, comprising a cup made of rigid material, sealingly fixed to the neck of the container, and a valve shutter made of flexible and elastic material, housed in an open tubular axial chimney of the cup, the obturator being hollowed out with a first blind tubular axial channel opening to the outside through an orifice surrounded by a tubular rim, for sealing the obturator on the end from the chimney outside the container, the shutter having, in the vicinity of the blind bottom of the first channel, an outer diametral annular widening forming a first valve cooperating by the elasticity of the shutter with a seat formed by the end of the chimney towards the outside of the container, the side wall of the obturator being pierced with at least one radial passage connecting the interior of the first channel to a first space delimited between the internal oi of the chimney and the external wall of the obturator comprised between the flange and the first valve, the first channel receiving, in an externally sealed manner, the end of a nozzle for filling the container with product injected under pressure through the valve, by axial elongation of the shutter from the rim, and detachment of the first valve from its seat under the effect of the pressure of the fluid injected by the nozzle, and, alternatively the tubular tail of a pusher-diffuser, for the distribution at will of the packaged product, by limited axial elongation of the shutter, under the effect of manual pressure exerted by the user on the diffusing pusher the shutter having an axial extension towards the interior of the container, hollowed out with a second blind axial channel opening out inside the container and receiving the end of a tube for supplying the product to be dispensed plunging to the bottom of the container (EP-A-80 750). The valve is characterized in that the extension has an external annular flange forming a second valve cooperating by the elasticity of the shutter with a seat formed by the internal wall of the cup in the vicinity of the chimney, valve which opens elastically. under the effect of the pressure of the fluid injected during filling, but which remains closed, in elastic support on its seat during the distribution of the product, the second supply channel of the product to be distributed opens out, through at least one radial passage , in a second space delimited between the internal wall of the cup and the external wall of the shutter comprised between the first valve and the second valve.

Dans une telle valve suivant l'invention, le second clapet peut être percé d'au moins un orifice calibré de passage de gaz faisant communiquer l'intérieur du récipient avec le second espace.In such a valve according to the invention, the second valve can be pierced with at least one calibrated orifice for the passage of gas making the interior of the container communicate with the second space.

Dans une forme d'exécution avantageuse, la partie marginale périphérique du second clapet porte élastiquement contre un épaulement de la coupelle dirigé vers l'intérieur du récipient, et limitant un prolongement tubulaire axial de la cheminée, de diamètre intérieur supérieur au diamètre extérieur du premier clapet.In an advantageous embodiment, the peripheral peripheral part of the second valve bears elastically against a shoulder of the cup directed towards the interior of the container, and limiting an axial tubular extension of the chimney, of internal diameter greater than the external diameter of the first valve.

Suivant un autre mode de réalisation, le second clapet présente une partie marginale périphérique rabattue en jupe vers l'intérieur du récipient et portant élastiquement contre une paroi intérieure cylindrique axiale de la coupelle prolongeant la cheminée et de diamètre intérieur supérieur au diamètre extérieur du premier clapet.According to another embodiment, the second valve has a peripheral marginal part folded in a skirt towards the interior of the container and bearing elastically against an axial cylindrical inner wall of the cup extending the chimney and of internal diameter greater than the external diameter of the first valve .

L'invention sera mieux comprise à la lecture de la description détaillée qui va suivre et à l'examen des dessins annexés qui représentent, à titre d'exemples non limitatifs deux modes de réalisation de l'invention.The invention will be better understood on reading the detailed description which follows and on examining the appended drawings which represent, by way of nonlimiting examples, two embodiments of the invention.

Sur ces dessins:

  • la figure 1 est une vue schématique en élévation et en coupe diamétrale d'une valve suivant l'invention, en position fermée ;
  • la figure 2 est une vue analogue à celle de la figure 1 de la même valve, lors du remplissage sous pression du récipient, sur lequel elle est montée ;
  • les figures 3 et 4 sont des vues analogues à celles des figures 1 et 2 d'un autre mode de réalisation.
In these drawings:
  • Figure 1 is a schematic elevational view in diametral section of a valve according to the invention, in the closed position;
  • Figure 2 is a view similar to that of Figure 1 of the same valve, when filling under pressure of the container, on which it is mounted;
  • Figures 3 and 4 are views similar to those of Figures 1 and 2 of another embodiment.

Sur ces différents dessins, les mêmes références numériques désignent les parties de valves correspondantes.In these various drawings, the same reference numerals designate the corresponding valve parts.

La valve représentée sur les figures 1 et 2 comprend essentiellement une coupelle 1 en métal et un obturateur 2 en matériau souple et élastique, tel qu'un polymère caoutchouteux. La coupelle, qui est du type dit "un pouce", largement utilisée dans l'industrie aérosol, présente une cheminée axiale 3 dans laquelle est logé l'obturateur.The valve shown in FIGS. 1 and 2 essentially comprises a cup 1 made of metal and a shutter 2 made of flexible and elastic material, such as a rubbery polymer. The cup, which is of the so-called "one inch" type, widely used in the aerosol industry, has an axial chimney 3 in which the shutter is housed.

L'obturateur est creusé d'un premier canal axial tubulaire borgne 5, débouchant à l'extérieur par un orifice entouré d'un rebord annulaire 4 qui prend appui de façon étanche contre l'extrémité extérieure de la cheminée 3. A partir du rebord 4, l'obturateur 2 se prolonge à l'intérieur de la cheminée 3 par une partie cylindrique jusqu'à un élargissement annulaire 6 constituant un premier clapet qui vient s'appuyer élastiquement contre un épaulement 7 limitant la cheminée 3 vers l'intérieur du récipient 25. La partie cylindrique de l'obturateur 2, entre le rebord 4 et le clapet 6, présente des saillies annulaires 27 garantissant une bonne étanchéité, et ménageant un espace 21 entre la paroi de l'obturateur 2 et la paroi de la cheminée 3. Deux perçages radiaux 8 et 9 font communiquer l'espace 21 avec l'intérieur 5 du canal axial. Dans ce canal axial, on introduit à volonté, soit l'extrémité tubulaire de la queue d'un poussoir diffuseur 11, soit une buse 10 d'injection de produit sous pression pour le remplissage du récipient 25 à travers la valve. La queue tubulaire du bouton-poussoir 11 communique avec l'intérieur du canal 5 par un perçage radial 28, ou encore par une fente de type classique, non représentée. L'intérieur de la buse d'injection 10 communique avec l'intérieur du canal 5, par deux orifices radiaux 29.The shutter is dug with a first channel axial tubular blind 5, opening to the outside through an orifice surrounded by an annular rim 4 which bears in leaktight manner against the external end of the chimney 3. From the rim 4, the shutter 2 extends to the inside the chimney 3 by a cylindrical part up to an annular widening 6 constituting a first valve which comes to bear elastically against a shoulder 7 limiting the chimney 3 towards the interior of the container 25. The cylindrical part of the shutter 2, between the rim 4 and the valve 6, has annular projections 27 guaranteeing a good seal, and providing a space 21 between the wall of the shutter 2 and the wall of the chimney 3. Two radial bores 8 and 9 communicate the space 21 with the interior 5 of the axial channel. In this axial channel, either the tubular end of the tail of a diffuser plunger 11 or a nozzle 10 for injecting pressurized product for filling the container 25 through the valve is introduced at will. The tubular tail of the push button 11 communicates with the interior of the channel 5 by a radial bore 28, or also by a slot of the conventional type, not shown. The interior of the injection nozzle 10 communicates with the interior of the channel 5, by two radial orifices 29.

Dans l'exemple représenté, le fond borgne 26 présente une protubérance axiale 30 qui vient s'insérer dans l'extrémité de la buse 10 ou de la queue de poussoir-diffuseur 11, pour en assurer à la fois un bon maintien latéral et une bonne étanchéité.In the example shown, the blind bottom 26 has an axial protuberance 30 which is inserted into the end of the nozzle 10 or of the pusher-diffuser tail 11, to ensure both good lateral support and a good sealing.

Au-delà du fond borgne 26, l'obturateur 2 présente un prolongement axial 12 en direction de l'intérieur du récipient 25. Ce prolongement est creusé d'un second canal axial borgne 13 qui débouche à l'intérieur du récipient et reçoit l'extrémité d'un tube 23 plongeant jusqu'au fond du récipient et amenant le liquide par deux perçages radiaux 17, 18 dans un espace 20 compris entre le premier clapet 26 et un deuxième clapet 14. Ce deuxième clapet 14 a une forme en coupe renversée dont le bord marginal 15 vient s'appuyer élastiquement contre un épaulement 22 de la coupelle 1, prolongeant une partie tubulaire 24. La partie tubulaire 24 a un diamètre intérieur supérieur au diamètre extérieur du clapet 6 en position de repos. Le second clapet 14 présente un perçage calibré 19 faisant communiquer l'intérieur du récipient avec l'espace précité 20.Beyond the blind bottom 26, the shutter 2 has an axial extension 12 towards the interior of the container 25. This extension is hollowed out by a second blind axial channel 13 which opens into the interior of the container and receives the end of a tube 23 plunging to the bottom of the container and bringing the liquid by two radial holes 17, 18 in a space 20 between the first valve 26 and a second valve 14. This second valve 14 has a sectional shape overturned, the marginal edge 15 of which abuts elastically against a shoulder 22 of the cup 1, extending a tubular part 24. The tubular part 24 has an inside diameter greater than the outside diameter of the valve 6 in the rest position. The second valve 14 has a calibrated bore 19 making the interior of the container communicate with the aforementioned space 20.

Lors du remplissage du récipient 25 en produit sous pression injecté par la buse 10, comme représenté sur la figure 2, où le trajet du produit injecté est indiqué par des fléches, l'obturateur 2 s'allonge à partir du rebord 4, sous l'effet, d'une part, de la poussée exercée sur la buse d'injection 10 et, d'autre part, sous l'effet de la pression exercée par le produit injecté qui décolle les clapets 6 et 14 de leurs sièges.When filling the container 25 with pressurized product injected by the nozzle 10, as shown in Figure 2, where the path of the injected product is indicated by arrows, the shutter 2 extends from the rim 4, under the 'Effect, on the one hand, of the thrust exerted on the injection nozzle 10 and, on the other hand, under the effect of the pressure exerted by the injected product which takes off the valves 6 and 14 from their seats.

Par contre, lorsque la valve est au repos, les clapets 6 et 14 appuient élastiquement contre leurs sièges respectifs 7 et 22, assurant ainsi une double étanchéité entre l'intérieur du récipient et l'extérieur.On the other hand, when the valve is at rest, the valves 6 and 14 press elastically against their respective seats 7 and 22, thus ensuring a double seal between the inside of the container and the outside.

Lorsque l'utilisateur exerce une pression manuelle sur le bouton-poussoir, la queue de celui-ci 11 étire l'obturateur 2 à partir de son rebord 4, jusqu'à ce que le premier clapet 6 décolle de son siège 7, comme indiqué en pointillés sur la figure 1. Cependant, le second clapet 14 glisse sur son siège 22 en maintenant l'étanchéité. Le produit parvient, par le tube plongeur 23, dans le canal 13 puis passe par les orifices 17, 18, dans l'espace 20 où il se mélange avec du gaz parvenant de l'intérieur du récipient, à travers l'orifice calibré 19. Le mélange passe ensuite entre le clapet 6 et son siège 7 pour parvenir dans la queue tubulaire 11 du poussoir-diffuseur, par les canaux radiaux 8 et 9, l'intérieur du canal 5 et le passage radial 28.When the user exerts manual pressure on the push-button, its tail 11 stretches the shutter 2 from its rim 4, until the first valve 6 takes off from its seat 7, as indicated in dotted lines in FIG. 1. However, the second valve 14 slides on its seat 22 while maintaining the seal. The product reaches, via the dip tube 23, in the channel 13 then passes through the orifices 17, 18, in the space 20 where it mixes with gas arriving from inside the container, through the calibrated orifice 19 The mixture then passes between the valve 6 and its seat 7 to reach the tubular tail 11 of the pusher-diffuser, by the radial channels 8 and 9, the interior of the channel 5 and the radial passage 28.

Dans le second mode de réalisation, représenté sur les figures 3 et 4, on retrouve les mêmes éléments affectés des mêmes références numériques, mais à la différence de modes de réalisation des figures 1 et 2, le second clapet 14 est en forme de collerette terminée par une jupe 16, qui porte normalement de façon étanche contre la paroi cylindrique tubulaire 24 prolongeant axialement le cheminée 3. Cette jupe 16 du second clapet 14 fonctionne ainsi de la même façon qu'un piston dans un cylindre. Elle assure un contact étanche du bord du second clapet 14 avec la paroi 24 de la coupelle 1 en toutes circonstances, sauf lors du remplissage sous pression, comme indiqué sur la figure 4.In the second embodiment, shown in Figures 3 and 4, we find the same elements assigned the same reference numerals, but unlike the embodiments of Figures 1 and 2, the second valve 14 is in the form of a completed flange by a skirt 16, which normally seals against the tubular cylindrical wall 24 axially extending the chimney 3. This skirt 16 of the second valve 14 thus operates in the same way as a piston in a cylinder. It ensures sealed contact of the edge of the second valve 14 with the wall 24 of the cup 1 in all circumstances, except during filling under pressure, as indicated in FIG. 4.

Bien entendu, l'invention n'est nullement limitée aux modes de réalisation de l'exemple décrit et représenté, elle est susceptible de nombreuses variantes accessibles à l'homme de l'art, suivant les applications envisagées et sans s'écarter pour cela du cadre de l'invention telle que definie dans les revendications. C'est ainsi que, sur les exemples représentés, la coupelle 1 est sertie sur le col du récipient 25. Elle pourrait aussi bien être encliquetée sur le col du récipient et être réalisée en matière plastique rigide, plut*ot qu'en métal.Of course, the invention is in no way limited to the embodiments of the example described and shown, it is capable of numerous variants accessible to those skilled in the art, depending on the applications envisaged and without departing from it. of the scope of the invention as defined in the claims. Thus, on the examples shown, the cup 1 is crimped onto the container neck 25. It could also be snapped onto the container neck and being made of a rigid plastic, rather than metal * ot.
