Abstract

The container comprises a reservoir (2), containing a pressurized product, with an opening (5) inside which a valve (7) is mounted. The valve comprises an opening/closing component able, in response to an activating command, to allow the distribution under pressure of the product through an outlet orifice (23). The opening/closing component, under the pressure inside the reservoir being exerted directly on a valve rod base (15) inside the container, interrupts the distribution when the activating command stops. Closure of the valve results from the engagement of the opening/closing component and a sealing joint (8) integral with the reservoir.

Description

La présente invention a trait à un récipient pour la distribution sous pression d'un produit, notamment liquide, tel qu'utilisé dans de nombreux domaines tels que la cosmétique, l'agro-alimentaire, ou la dermato-pharmacologie.The present invention relates to a container for the pressure distribution of a product, especially liquid, as used in many fields such as cosmetic, agro-food, or dermato-pharmacology.

Typiquement, un récipient aérosol comporte un réservoir, formé d'un bidon, le plus souvent en métal ou en plastique, et dont un bord libre délimite une ouverture dans laquelle est montée une valve. La valve est généralement montée sur une coupelle, "sertie" ou "dudgeonnée" sur le bord libre du bidon. A l'intérieur du bidon, est disposé le produit, généralement sous forme liquide, ainsi qu'un gaz propulseur, mélangé ou non au produit à distribuer.Typically, an aerosol container has a reservoir, formed of a container, most often made of metal or plastic, and with a free edge delimiting an opening in which a valve is mounted. The valve is usually mounted on a cup, "set" or "dudgeonnée" on the free edge of the container. Inside the container, is placed the product, generally in liquid form, as well as a gas propellant, mixed or not with the product to be dispensed.

La valve comporte un corps de valve, généralement cylindrique, et présentant un orifice d'entrée et un orifice de sortie. A l'intérieur du corps de valve est disposé un organe d'ouverture/fermeture, pouvant être sous forme d'une tige dont une partie est disposée à l'intérieur du corps de valve, et dont une autre partie émerge à l'extérieur du corps de valve. Sur la partie émergente de la tige de valve, est monté un organe d'actionnement sous forme d'un bouton poussoir, lequel comporte au moins un orifice pour la sortie du produit. La tige de valve, est traversée axialement par un canal, débouchant, via au moins une portion radiale, à l'intérieur du corps de valve.The valve comprises a valve body, generally cylindrical, and having a inlet port and an outlet port. Inside the valve body is arranged a opening / closing member, which may be in the form of a rod, part of which is arranged inside the valve body, and another part of which emerges at outside the valve body. On the emerging part of the valve stem, is mounted an actuator in the form of a push button, which has at least one orifice for the outlet of the product. The valve stem, is crossed axially by a channel, opening, via at least one radial portion, inside the valve body.

Selon une configuration possible, en position fermée de la valve, la portion radiale du canal débouche en regard du bord annulaire intérieur d'un joint d'étanchéité, disposé autour de l'orifice de sortie du corps de valve. L'organe d'ouverture/fermeture est contraint dans cette position de fermeture au moyen d'un ressort disposé à l'intérieur du corps de valve. Pour distribuer du produit, l'utilisateur exerce une pression sur une surface d'appui du bouton poussoir, laquelle pression est suffisante pour vaincre la force de rappel du ressort, et provoquer l'enfoncement de la tige de valve, jusqu'à ce que la, ou les portions radiales du canal traversant la tige de valve, ne soient plus en regard du joint d'étanchéité. A ce moment, le produit sous pression à l'intérieur du corps de valve, remonte dans la tige de valve, et est acheminé vers l'orifice de sortie de l'organe d'actionnement, via au moins un passage reliant ledit orifice de sortie à la tige de valve sur laquelle est monté l'organe d'actionnement. En relâchant la pression sur la surface d'appui de l'organe d'actionnement, le ressort rappelle l'organe d'ouverture/fermeture en position fermée. La distribution du produit est alors interrompue.According to a possible configuration, in the closed position of the valve, the radial portion the channel opens opposite the inner annular edge of a seal, arranged around the outlet orifice of the valve body. The organ opening / closing is forced in this closed position by means a spring disposed inside the valve body. To distribute product, the user exerts pressure on a support surface of the push button, which pressure is sufficient to overcome the return force of the spring, and cause the valve stem to sink in until the portion (s) radials of the channel passing through the valve stem, no longer facing the seal sealing. At this time, the product under pressure inside the valve body, goes back into the valve stem, and is routed to the organ outlet actuation, via at least one passage connecting said outlet orifice to the rod valve on which the actuator is mounted. By releasing the pressure on the bearing surface of the actuating member, the spring recalls the member opening / closing in closed position. The distribution of the product is then interrupted.

Outre le surcoût qu'il occasionne, le ressort complique le montage d'une telle valve. De plus, le ressort doit être choisi en un matériau compatible avec la composition à distribuer. La présence du ressort oblige en outre à avoir un corps de valve pour le maintien du ressort en engagement avec l'organe d'ouverture/fermeture.In addition to the additional cost it causes, the spring complicates the assembly of such a valve. In addition, the spring must be chosen from a material compatible with the composition to distribute. The presence of the spring also requires having a body valve for holding the spring in engagement with the organ opening / closing.

Il a été proposé par ailleurs, une valve comportant un corps de valve en matériau élastomérique. L'élasticité du matériau formant le corps de valve est utilisée pour contraindre l'organe d'ouverture/fermeture en position fermée. Un des inconvénients d'une telle conception tient au problème de compatibilité qui peut exister dans certains cas entre l'élastomère formant le corps de valve et le produit à distribuer.A valve has also been proposed comprising a valve body made of material elastomeric. The elasticity of the material forming the valve body is used to force the opening / closing member in the closed position. One of disadvantages of such a design is due to the compatibility problem which can exist in some cases between the elastomer forming the valve body and the product to distribute.

Le brevet US 5 623 920 décrit un récipient aérosol dont la valve ne comporte pas de ressort proprement dit. Toutefois, selon ce document, le récipient aérosol est monté mobile axialement à l'intérieur d'une enceinte extérieure, et le rappel en position fermée de la valve résulte de la force de rappel d'un ressort placé entre le fond du récipient et ladite enceinte extérieure, la tige de valve étant à position axiale fixe par rapport au récipient mobile.US Patent 5,623,920 describes an aerosol container whose valve does not include spring itself. However, according to this document, the aerosol container is mounted axially movable inside an external enclosure, and the return closed position of the valve results from the return force of a spring placed between the bottom of container and said outer enclosure, the valve stem being in position axial fixed with respect to the mobile container.

Le brevet US 4 852 807 décrit un dispositif aérosol dans laquelle la valve ne comporte pas de corps de valve proprement dit. La tige de valve est disposée dans une structure dont une partie forme ressort de manière à rappeler la valve en position de fermeture lorsque cesse la commande d'actionnement.US Patent 4,852,807 describes an aerosol device in which the valve does not has no actual valve body. The valve stem is arranged in a structure of which a part forms a spring so as to recall the valve in closed position when the actuation command ceases.

Le brevet FR 1 379 202 décrit un dispositif de soupape dans lequel un élément élastique, fixé au récipient, est prévu pour assurer le retour de la valve en position de fermeture lorsque cesse la commande d'actionnement. Patent FR 1 379 202 describes a valve device in which an element elastic, fixed to the container, is provided to ensure the return of the valve in position closing when the actuation command ceases.

Le brevet US 3 990 613 décrit également un dispositif aérosol muni d'une valve qui comprend un élément élastique prévu pour assurer le retour de la valve en position de fermeture. La fermeture de la valve résulte de la coopération entre un joint d'étanchéité, solidaire de la valve, et la paroi interne du récipient.US Patent 3,990,613 also describes an aerosol device provided with a valve which includes an elastic element designed to ensure the return of the valve in closed position. The closure of the valve results from the cooperation between a seal, integral with the valve, and the internal wall of the container.

Le brevet US 3 682 355 décrit un dispositif aérosol muni d'une valve qui sous l'action de la pression à l'intérieur du récipient assure son retour en position de fermeture lorsque cesse la commande d'actionnement. La valve est constituée d'une tige de valve mobile sous l'action d'un levier. Un disque annulaire est prévu à l'intérieur du récipient pour assurer l'étanchéité du récipient. Le disque est maintenu en appui sur un siège sous l'action de la pression à l'intérieur du récipient et est décollé de son siège par la tige qui vient appuyer dessus lorsque le levier est basculé. L'élément annulaire n'est pas solidaire de la tige de valve. Un tel dispositif comprend plusieurs pièces indépendantes ce qui ne facilite pas son montage. En outre, le fait que l'élément annulaire et la tige ne soient pas solidaires entraíne forcément la présence d'un jeu entre ces deux pièces qui ne permet pas une ouverture immédiate de la valve lors de la commande d'actionnement.US Patent 3,682,355 describes an aerosol device provided with a valve which under the action of the pressure inside the container ensures its return to the closing when the actuation command ceases. The valve is made up a movable valve stem under the action of a lever. An annular disc is provided inside the container to seal the container. The disc is kept pressed on a seat under the action of pressure inside the container and is lifted from its seat by the rod which comes to press on it when the lever is tilted. The annular element is not integral with the valve stem. A such a device comprises several independent parts which does not facilitate its mounting. In addition, the fact that the annular element and the rod are not integral necessarily entails the presence of a play between these two parts which does not allow immediate opening of the valve during actuation control.

Aussi, est-ce un des objets de l'invention que de réaliser un récipient, notamment de type récipient aérosol, et résolvant en tout ou partie les problèmes discutés ciavant en référence aux récipients conventionnels.It is therefore one of the objects of the invention to produce a container, in particular aerosol container type, and solving all or part of the problems discussed above with reference to conventional containers.

D'autres objets encore apparaítront dans la description détaillée qui suit.Still other objects will appear in the detailed description which follows.

De manière surprenante, la demanderesse a découvert que le retour en position fermée d'une telle valve, ainsi que son maintien dans ladite position fermée pouvaient être assurés par la seule pression régnant à l'intérieur du récipient, permettant ainsi de s'affranchir de la présence d'un ressort ou de tout autre organe de rappel élastique, ainsi qu'éventuellement de la présence d'un corps de valve.Surprisingly, the plaintiff discovered that the return to position closed of such a valve, as well as its maintenance in said closed position could be ensured by the only pressure prevailing inside the container, thus eliminating the presence of a spring or any other elastic return member, as well as possibly the presence of a body of valve.

Selon l'invention, ces objets sont atteints en réalisant un récipient comprenant un réservoir contenant un produit sous pression, ledit réservoir comportant une ouverture à l'intérieur de laquelle est montée une valve, ladite valve comprenant un élément d'ouverture/fermeture apte, en réponse à une commande d'actionnement, à autoriser la distribution sous pression du produit au travers d'au moins un orifice de sortie, ledit élément d'ouverture/fermeture, essentiellement sous l'action de la pression à l'intérieur du réservoir s'exerçant directement sur un organe disposé à l'intérieur du récipient, interrompant la distribution lorsque cesse la commande d'actionnement, ledit élément d'ouverture/fermeture étant solidaire dudit organe, la fermeture de ladite valve résultant de la coopération entre l'élément d'ouverture/fermeture et un joint d'étanchéité solidaire du réservoir.According to the invention, these objects are achieved by producing a container comprising a tank containing a product under pressure, said tank comprising a opening inside which a valve is mounted, said valve comprising a suitable opening / closing element, in response to an order actuation, to authorize the distribution under pressure of the product through at least at least one outlet, said opening / closing element, essentially under the action of pressure inside the tank acting directly on a organ placed inside the container, interrupting the distribution when it stops the actuation command, said opening / closing element being integral said organ, the closure of said valve resulting from cooperation between the opening / closing element and a seal integral with the tank.

Ainsi, on s'affranchit à la fois de la présence du ressort et éventuellement du corps de valve. En outre, on s'affranchit également de la présence de certains matériaux élastomériques, susceptibles de poser des problèmes de compatibilité avec certains produits. Par ailleurs, le montage d'une telle valve est simplifié de manière substantielle. Enfin, le fait que l'organe sur lequel s'exerce la pression et l'élément d'ouverture/fermeture soient solidaires permet une ouverture immédiate de la valve lors de la commande d'actionnement, et donc d'obtenir un dispositif fiable.Thus, we are freed from both the presence of the spring and possibly the body valve. In addition, it also overcomes the presence of certain materials elastomeric, which may cause compatibility problems with some products. Furthermore, the mounting of such a valve is simplified so substantial. Finally, the fact that the organ on which the pressure is exerted and the element opening / closing are integral allows immediate opening of the valve during the actuation command, and therefore to obtain a reliable device.

Le terme "essentiellement" traduit le fait qu'en raison du montage à la fois étanche et à coulisse de l'organe d'ouverture/fermeture par rapport au joint d'étanchéité, typiquement sous forme d'un joint élastomérique, le joint d'étanchéité peut, lorsque cesse la commande d'actionnement, avoir une action participant de façon marginale au rappel de l'élément d'ouverture/fermeture en position fermée. Toutefois, cette action est négligeable par rapport à celle exercée par la pression régnant à l'intérieur du récipient, laquelle participe, à plus de 50 %, au rappel de l'élément d'ouverture/fermeture, de préférence à plus de 75 %, et de préférence encore à plus de 90 %.The term "essentially" reflects the fact that due to the tight fitting and sliding of the opening / closing member with respect to the seal, typically in the form of an elastomeric seal, the seal may, when the actuation command ceases, have a participating action so marginal to the recall of the opening / closing element in the closed position. However, this action is negligible compared to that exerted by pressure prevailing inside the container, which participates more than 50% in the recall of the opening / closing element, preferably more than 75%, and preferably still over 90%.

Le propulseur peut être un gaz liquéfié ou non. Dans l'hypothèse d'un gaz liquéfié ou non, il est en général plus léger que le produit à distribuer, de sorte que, pour être utilisé tête en haut, il est nécessaire d'associer un tube plongeur à la valve. A cet effet, la valve peut comporter un corps de valve dont un orifice d'entrée est relié au tube plongeur, une extrémité libre du tube plongeur étant située au voisinage du fond du récipient. Dans le cas d'une utilisation tête en bas, un tel tube plongeur et un tel corps de valve ne sont pas nécessaires. Alternativement, le gaz propulseur peut être séparé du produit par un piston, ou par une poche à parois souples, définissant un volume intérieur contenant le produit.The propellant may or may not be a liquefied gas. Assuming a liquefied gas or not, it is generally lighter than the product to be distributed, so that, for be used head up, it is necessary to associate a dip tube with the valve. AT For this purpose, the valve may include a valve body of which an inlet is connected to the dip tube, a free end of the dip tube being located at the near the bottom of the container. In the case of use upside down, such dip tube and such a valve body are not required. Alternatively, the propellant can be separated from the product by a piston, or by a flexible walls, defining an interior volume containing the product.

Avantageusement, l'organe sur lequel s'exerce la pression à l'intérieur du réservoir est solidaire uniquement de l'élément d'ouverture/fermeture. Autrement dit, l'organe est libre de tout couplage autre que sa fixation à l'élément d'ouverture/fermeture contrairement à l'organe décrit dans le brevet FR 1 379 202, ce qui permet, là encore, de simplifier de manière substantielle le montage d'une telle valve. En outre, la pression à l'intérieur du récipient nécessaire pour assurer la fermeture de la valve est moins élevée lorsque l'organe est libre que lorsqu'il est fixé au récipient. On peut ainsi s'affranchir de tout rappel élastique pour fermer la valve et n'utiliser essentiellement que la pression à l'intérieur du récipient.Advantageously, the member on which the pressure is exerted inside the tank is integral only with the opening / closing element. In other words, the member is free of any coupling other than its attachment to the element opening / closing unlike the device described in patent FR 1 379 202, which again makes it possible to substantially simplify the mounting of a such valve. In addition, the pressure inside the container necessary to ensure the valve closure is lower when the organ is free than when it is attached to the container. We can thus get rid of any elastic reminder to close the valve and essentially only use the pressure inside the container.

Avantageusement encore, ledit élément d'ouverture/fermeture comprend une tige de valve, pouvant coulisser de manière étanche à l'intérieur d'un passage ménagé dans le joint d'étanchéité disposé dans ladite ouverture, ladite tige étant traversée par un canal axial se prolongeant par au moins une portion radiale destinée à être mise en communication avec le produit sous pression à l'intérieur du réservoir, en réponse à ladite commande d'actionnement.Advantageously also, said opening / closing element comprises a rod valve, able to slide tightly inside a passage in the seal placed in said opening, said rod being traversed by an axial channel extending by at least one radial portion intended to be communication with the pressurized product inside the tank, response to said actuation command.

Typiquement, un tel organe d'ouverture/fermeture présente à l'intérieur du récipient une base formée de façon continue ou discontinue autour de la tige de valve, et assurant d'une part la retenue de la valve sur le récipient, et éventuellement l'étanchéité à la fermeture. La base est inscrite dans un cercle de section S3 plus grande que la section S2 de la tige de valve. En raison du gradient de pression, la force exercée sur une première face de ladite base annulaire, tournée en direction du fond du récipient est supérieure à la force s'exerçant sur une deuxième face de ladite base annulaire, opposée à la première (dans l'hypothèse où la pression à l'intérieur du récipient est supérieure à la pression atmosphérique). Ainsi, un premier différentiel de force participe au retour de la valve en position fermée.Typically, such an opening / closing member has inside the container a base formed continuously or discontinuously around the valve stem, and ensuring on the one hand the retention of the valve on the container, and possibly the sealing on closing. The base is inscribed in a circle of section S 3 larger than the section S 2 of the valve stem. Due to the pressure gradient, the force exerted on a first face of said annular base, turned towards the bottom of the container is greater than the force exerted on a second face of said annular base, opposite to the first (in the assumption that the pressure inside the container is higher than atmospheric pressure). Thus, a first force differential participates in the return of the valve to the closed position.

En outre, et toujours dans l'hypothèse où la pression à l'intérieur du récipient est supérieure à la pression atmosphérique, la force s'exerçant sur la section S2 de l'extrémité de la tige de valve à l'intérieur du récipient est supérieure à la force s'exerçant sur la section S2 de l'extrémité de la tige de valve située à l'extérieur du récipient. Il existe donc un second différentiel de force qui participe également au retour de la valve en position fermée.In addition, and always assuming that the pressure inside the container is higher than atmospheric pressure, the force exerted on the section S 2 of the end of the valve stem inside the container is greater than the force exerted on the section S 2 of the end of the valve stem located outside the container. There is therefore a second force differential which also contributes to the return of the valve to the closed position.

Le second différentiel de force dépend en réalité du gradient de pression à l'intérieur du canal axial traversant la tige de valve. En effet, la pression moyenne à l'intérieur du canal axial est une pression dont la valeur se situe quelque part entre la pression atmosphérique et la pression à l'intérieur du récipient. Dans tous les cas, le différentiel de force est tel, que l'organe d'ouverture/fermeture est contraint à reprendre sa position de fermeture.The second force differential actually depends on the pressure gradient at inside the axial channel passing through the valve stem. Indeed, the average pressure inside the axial channel is a pressure whose value is somewhere between atmospheric pressure and the pressure inside the container. In all in cases, the force differential is such that the opening / closing member is forced to return to its closed position.

Ainsi, à l'intérieur du récipient, la pression est telle, que, tout au long de la durée de vie du produit, elle est au moins supérieure à la pression atmosphérique, la différence de pression nécessaire étant choisie notamment en fonction de la rapidité requise à la fermeture, et de la résistance souhaitée à l'ouverture afin de minimiser les risques de distribution accidentelle. Dans la pratique, on intégrera en outre un surplus de pression pour compenser les frottements entre la tige de valve et le joint d'étanchéité, ainsi que le poids de la tige de valve et du bouton poussoir, lesquels sont généralement négligeables.So, inside the container, the pressure is such that, throughout the duration life of the product, it is at least higher than atmospheric pressure, the required pressure difference being chosen in particular according to the speed required for closing, and the desired resistance to opening in order to minimize the risk of accidental distribution. In practice, we will integrate in addition to excess pressure to compensate for friction between the valve stem and the gasket, as well as the weight of the valve stem and the push button, which are generally negligible.

Selon un premier mode de réalisation, la commande d'actionnement est telle qu'elle provoque un enfoncement axial de la tige de valve. Alternativement, la commande d'actionnement est telle qu'elle provoque un basculement de la tige de valve.According to a first embodiment, the actuation command is such that it causes axial depression of the valve stem. Alternatively, the actuation control is such that it causes the tilting rod to tip over valve.

De préférence, sur sa portion située à l'extérieur du récipient, la tige de valve comporte des moyens formant butée, aptes à limiter l'enfoncement de la tige de valve à l'intérieur du récipient en réponse à ladite commande d'actionnement.Preferably, on its portion located outside the container, the valve stem comprises means forming a stop, capable of limiting the sinking of the rod valve inside the container in response to said actuation command.

Dans une première configuration du récipient aérosol selon l'invention, en position fermée de l'élément d'ouverture/fermeture, ladite (ou lesdites) portion(s) radiale(s) débouche(nt) en regard d'un bord annulaire intérieur du joint d'étanchéité, l'enfoncement axial de la tige de valve en réponse à ladite commande d'actionnement, provoquant un déplacement de ladite (ou desdites) portion(s) radiale(s) par rapport audit bord annulaire intérieur du joint d'étanchéité, et la mise en communication dudit orifice de sortie avec le produit sous pression.In a first configuration of the aerosol container according to the invention, in position closed of the opening / closing element, said (or said) radial portion (s) opens (s) opposite an inner annular edge of the seal, axial insertion of the valve stem in response to said command actuation, causing a displacement of said portion (s) radial (s) with respect to said inner annular edge of the seal, and placing in communication with said outlet orifice with the product under pressure.

Dans une seconde configuration du récipient aérosol selon l'invention, en position fermée de l'élément d'ouverture/fermeture, ladite (ou lesdites) portion(s) radiale(s) débouche(nt) en regard, d'une zone annulaire délimitée par une couronne annulaire qui, en position fermée de l'élément d'ouverture/fermeture, est en appui étanche sur une surface annulaire du joint d'étanchéité, l'enfoncement axial ou le basculement de la tige de valve en réponse à ladite commande d'actionnement, provoquant un déplacement de ladite couronne annulaire par rapport à ladite surface du joint d'étanchéité, et la mise en communication dudit orifice de sortie avec le produit sous pression.In a second configuration of the aerosol container according to the invention, in position closed of the opening / closing element, said (or said) radial portion (s) opens (s) opposite, an annular zone delimited by a crown annular which, in the closed position of the opening / closing element, bears watertight on an annular surface of the seal, the axial recess or the tilting of the valve stem in response to said actuation command, causing a displacement of said annular ring relative to said surface of the seal, and the communication of said outlet orifice with the product under pressure.

De préférence, ladite commande d'actionnement est exercée via un organe d'actionnement sous forme d'un bouton poussoir, monté sur ledit élément d'ouverture/fermeture, et dans lequel est (sont) ménagé(s) ledit (lesdits) orifice(s) de sortie. Ledit orifice de sortie peut être ménagé dans une buse, notamment à canaux tourbillonnaires.Preferably, said actuation control is exerted via a member actuation in the form of a push button, mounted on said element opening / closing, and in which is (are) (s) said (said) orifice (s) Release. Said outlet orifice can be formed in a nozzle, in particular at vortex channels.

Avantageusement, au moins la surface d'un bord délimitant ledit orifice du joint d'étanchéité, est recouverte d'un revêtement, notamment de silicone ou téflon, de manière à favoriser le coulissement de la tige émergente dans ledit orifice.Advantageously, at least the surface of an edge delimiting said orifice of the joint sealing, is covered with a coating, in particular of silicone or teflon, of so as to favor the sliding of the emerging rod in said orifice.

Le récipient selon l'invention peut être utilisé pour le conditionnement et la distribution d'un produit cosmétique, notamment d'un produit capillaire (laque coiffante, spray), de soin, de maquillage ou d'hygiène corporelle.The container according to the invention can be used for packaging and distribution of a cosmetic product, in particular a hair product (hairspray styling, spray), care, makeup or personal hygiene.

The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which
  • FIG. 1 represents an overall view of a first embodiment of the container according to the invention, suitable for upside down distribution;
  • Figure 2 schematically illustrates the operation of the container of Figure 1;
  • Figure 3 illustrates a perspective view of the valve opening / closing member used in the container of Figures 1 and 2; and
  • FIG. 4 illustrates a perspective view of the valve opening / closing member according to a second embodiment.

Le récipient aérosol 1 illustré à la figure 1 comprend un bidon cylindrique 2, d'axe X, réalisé notamment en aluminium ou en fer blanc. Une extrémité du bidon 2 est fermée par un fond 3. A l'intérieur du récipient, est disposé un produit à distribuer ainsi qu'un gaz propulseur, notamment du butane. La pression initiale à l'intérieur du récipient est de l'ordre de quelques bars. L'extrémité opposée au fond 3 présente un bord roulé 4 délimitant une ouverture 5. Sur le bord roulé 4 du récipient, est sertie une coupelle 6 portant une valve 7. A l'intérieur de la coupelle 6, est disposé un joint annulaire 8 dont le bord périphérique est maintenu entre le bord roulé 4 et la coupelle porte valve 6, assurant ainsi le montage étanche de la coupelle 6 sur le récipient 2. A l'intérieur du passage central 9 délimité par le bord intérieur 10 du joint annulaire 8, est monté coulissant un organe d'ouverture/fermeture 11. L'organe d'ouverture/fermeture 11 comprend une tige de valve 12 coulissant de manière étanche dans le passage 9 du joint 8, et émergeant à l'extérieur de la coupelle 6 via un orifice disposé en regard du passage 9 traversant le joint 8.The aerosol container 1 illustrated in FIG. 1 comprises a cylindrical container 2, of axis X, made in particular of aluminum or tinplate. One end of container 2 is closed by a bottom 3. Inside the container, is arranged a product to be dispensed as well as a propellant, in particular butane. The initial pressure inside of the container is of the order of a few bars. The end opposite the bottom 3 has a rolled edge 4 defining an opening 5. On the rolled edge 4 of the container, is set with a cup 6 carrying a valve 7. Inside the cup 6, an annular seal 8 is arranged, the peripheral edge of which is held between the rolled edge 4 and the valve holder cup 6, thus ensuring the watertight mounting of the cup 6 on the container 2. Inside the central passage 9 delimited by the edge inside 10 of the annular seal 8, a member is slidably mounted opening / closing 11. The opening / closing member 11 comprises a rod valve 12 sliding in leaktight manner in passage 9 of seal 8, and emerging outside of the cup 6 via an orifice placed opposite the passage 9 passing through the seal 8.

Sur sa partie située à l'extérieur du récipient 2, la tige de valve 12 présente une portion 25, de section plus grande que la section du passage 9 traversant le joint 8, de manière à empêcher, avant la mise sous pression du récipient, et avant le montage du bouton poussoir dont on parlera par la suite, que l'organe d'ouverture/fermeture ne tombe dans le récipient 2.On its part located outside the container 2, the valve stem 12 has a portion 25, of section larger than the section of passage 9 passing through the joint 8, so as to prevent, before the pressurization of the container, and before the mounting of the push button which will be discussed later, that the organ does not fall into the container 2.

La tige de valve 12 est traversée par un canal axial 13 se terminant au voisinage de l'extrémité inférieure de la tige de valve 12, par un canal 14 traversant radialement la tige 12, et débouchant en deux points diamétralement opposés de la tige 12. En son extrémité disposée à l'intérieur du récipient, la tige de valve se termine par une base 15, constituée d'une paroi transversale de section S3 supérieure à la section S2 de la tige de valve 12. Sur sa face tournée dans la direction opposée au fond 3 du récipient 2, la base 15 forme une couronne périphérique 16 dont un bord libre est apte, sous l'effet de la pression régnant à l'intérieur du récipient 2, à venir s'appliquer de manière étanche sur une face correspondante 17 du joint d'étanchéité 8. Un organe d'ouverture/fermeture 11 selon ce mode de réalisation, est représenté sur la vue en perspective de la figure 3.The valve stem 12 is crossed by an axial channel 13 ending in the vicinity of the lower end of the valve stem 12, by a channel 14 radially passing through the stem 12, and emerging at two diametrically opposite points of the stem 12. At its end disposed inside the container, the valve stem ends in a base 15, consisting of a transverse wall of section S 3 greater than the section S 2 of the valve stem 12. On its face turned in the direction opposite to the bottom 3 of the container 2, the base 15 forms a peripheral crown 16 of which a free edge is capable, under the effect of the pressure prevailing inside the container 2, of being applied in a sealed manner on a corresponding face 17 of the seal 8. An opening / closing member 11 according to this embodiment, is shown in the perspective view of FIG. 3.

En position fermée de la valve 7, le canal radial 14 débouche dans un espace annulaire délimité par la base 15 de la tige de valve 12, la couronne annulaire 16, et le joint 8.In the closed position of the valve 7, the radial channel 14 opens into a space annular delimited by the base 15 of the valve stem 12, the annular crown 16, and seal 8.

Sur son extrémité opposée à la base 15, est monté à force, un bouton poussoir 20, traversé par un passage 21 débouchant sur une buse 22 dans laquelle est ménagé un orifice de sortie 23. Le bouton poussoir définit une surface d'appui 24 destinée à permettre à l'utilisateur d'actionner la valve 7, en vue de distribuer le produit contenu dans le récipient. Le bouton poussoir 20, de même que l'organe d'ouverture/fermeture 11 de la valve 7 peuvent être obtenus de moulage d'un matériau thermoplastique tel qu'un polypropylène ou un polyéthylène.On its end opposite the base 15, a push button is mounted by force 20, crossed by a passage 21 leading to a nozzle 22 in which is formed an outlet orifice 23. The push button defines a bearing surface 24 intended to allow the user to actuate the valve 7, in order to distribute the product contained in the container. The push button 20, as well as the organ opening / closing 11 of valve 7 can be obtained by molding a thermoplastic material such as polypropylene or polyethylene.

Dans la position fermée illustrée à la figure 1, la pression régnant à l'intérieur du récipient, et qui s'exerce sur la totalité de la section S3, contraint la couronne annulaire 16 en appui étanche sur la face 17 du joint 8.In the closed position illustrated in FIG. 1, the pressure prevailing inside the container, and which is exerted over the entire section S 3 , constrains the annular ring 16 in sealed support on the face 17 of the seal 8.

Ainsi qu'illustré à la figure 2, après avoir retourné le récipient tête en bas, lorsque l'utilisateur exerce une pression (sensiblement dans l'axe X) sur la surface 24 du bouton poussoir, la force qu'il exerce est suffisante pour vaincre la force s'appliquant sur la section S3, et résultant de la pression régnant à l'intérieur du récipient 2. De ce fait, la tige de valve 12 s'enfonce axialement, ce qui provoque la rupture d'étanchéité au niveau de la couronne annulaire 16. Le produit, localisé au voisinage de la valve, en raison de la position tête en bas du récipient, s'engouffre dans le canal radial 14, remonte dans le canal axial 13 de la tige de valve, circule dans le passage 21 du bouton poussoir 20 et est distribué via l'orifice de sortie 23. Lorsque l'utilisateur relâche la pression sur la surface 24, les différentiels de force auxquels il a été fait référence précédemment provoquent la remontée axiale de l'organe de fermeture 11, jusqu'à ce que la couronne annulaire 16 soit à nouveau en appui étanche sur la face 17 du joint d'étanchéité 8.As illustrated in FIG. 2, after having turned the container upside down, when the user exerts pressure (substantially in the X axis) on the surface 24 of the push button, the force that he exerts is sufficient to overcome the force applied to the section S 3 , and resulting from the pressure prevailing inside the container 2. As a result, the valve stem 12 sinks axially, which causes the seal to rupture at the level of the annular crown 16. The product, located in the vicinity of the valve, due to the upside-down position of the container, rushes into the radial channel 14, rises in the axial channel 13 of the valve stem, circulates in the passage 21 of the push button 20 and is distributed via the outlet orifice 23. When the user releases the pressure on the surface 24, the force differentials to which reference has been made previously cause the axial member to rise closing 11, until the annular ring 16 is again sealed against the face 17 of the seal 8.

Le mode de réalisation qui précède est adapté à la fois à un fonctionnement de la valve par enfoncement et par basculement latéral.The above embodiment is adapted both to an operation of the valve by pushing in and lateral tilting.

L'organe de fermeture 11 représenté à la figure 4 diffère de celui discuté en référence au mode de réalisation précédent en ce que la base 15 est constituée d'une pluralité de pattes 30, 31, 32 orientées radialement, et espacées de manière régulière tout autour de la tige de valve 12, au voisinage de son extrémité inférieure. Le canal radial 14 est à une distance telle de l'extrémité inférieure de la tige de valve 12, que lorsque la valve est en position fermée, le canal radial 14 débouche en regard du bord intérieur 10 du joint annulaire 8. En l'absence de pression d'actionnement, le canal radial est maintenu en regard du bord intérieur 10 du joint 8 en raison de la pression régnant à l'intérieur du récipient, et s'exerçant à la fois sur la section transversale S2 de la tige de valve 12, et sur la section totale des pattes 30, 31, 32. A l'inverse du mode de réalisation précédent, avec une telle configuration, l'ouverture de la valve ne peut se faire que par enfoncement.The closure member 11 shown in FIG. 4 differs from that discussed with reference to the previous embodiment in that the base 15 consists of a plurality of legs 30, 31, 32 oriented radially, and evenly spaced apart. around the valve stem 12, near its lower end. The radial channel 14 is at such a distance from the lower end of the valve stem 12 that, when the valve is in the closed position, the radial channel 14 opens facing the inner edge 10 of the annular seal 8. In the absence actuation pressure, the radial channel is maintained opposite the inner edge 10 of the seal 8 due to the pressure prevailing inside the container, and acting both on the cross section S 2 of the rod valve 12, and on the total section of the legs 30, 31, 32. Unlike the previous embodiment, with such a configuration, the opening of the valve can only be done by pressing.

Lorsqu'une pression est exercée sur la surface d'appui 24 du bouton poussoir 20, le canal radial 14 n'est plus en regard du bord 10 du joint 8, et le produit est distribué via, le canal radial 14, le canal axial 13, le passage 21, et l'orifice de sortie 23. Lorsque l'utilisateur relâche la pression sur la surface 24 du bouton poussoir 20, le retour en position fermée de la valve 7 se fait de la même manière que pour le mode de réalisation précédent, à savoir en réponse aux différentiels de force résultant des différentiels de pression.When pressure is exerted on the bearing surface 24 of the push button 20, the radial channel 14 is no longer opposite the edge 10 of the seal 8, and the product is distributed via, the radial channel 14, the axial channel 13, the passage 21, and the orifice exit 23. When the user releases the pressure on the surface 24 of the button pusher 20, the valve 7 returns to the closed position in the same way than for the previous embodiment, namely in response to the differentials force resulting from pressure differentials.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. Obviously there may be variations made without departing from the spirit of the invention as claimed below.
