Definitions

  • the present invention relates to a device for the simultaneous distribution of two products packaged separately according to the preamble of claim 1.
  • the invention is particularly suitable for the application of certain products used in cosmetics, pharmacy or dermato-pharmacology.
  • the invention relates in particular to products which, for reasons of stability cannot be brought into contact with each other, until the time of use.
  • active agents such as vitamin C, A, or E, bicarbonate, fruit acids such as citric acid, to be distributed with a moisturizing product in the form of a gel, d 'a cream or cream gel.
  • Patent FR-A-2 615 826 describes a device for the distribution of a mixture of pasty substance and at least one pasty additive, in particular in the form of a striated bead.
  • the device comprises a container, in particular a tube with flexible walls, containing a first pasty product.
  • the container is surmounted by a neck on which a dispensing head is mounted.
  • the dispensing head has a body, an annular part of which forms a reservoir for a second product, capable of exiting through an outlet orifice, under the pressure of the first product.
  • the body also defines a central passage for conveying the first product to said outlet orifice, so as to form a ridged bead comprising a little of the two products.
  • the second product is contained in a central part of the body of the dispensing head, the first product being in turn conveyed by an annular passage.
  • the respective flow rates of each of the products are determined to a large extent by the diameter of the neck of the container with flexible walls, and by the configuration of the body of the dispensing head, etc.
  • the body containing the second product has an added bottom.
  • the configuration of the bottom is such that it does not in any way modify the flow of product leaving the flexible-walled tube. It therefore has no impact on the respective flow rates of each product.
  • a device comprising the characteristics of the preamble of claim 1 is known from document EP-A-0 737 629.
  • the body consists of a single piece obtained from molding, in particular of a thermoplastic material such as polypropylene, a polyethylene terephthalate, a polyethylene, etc.
  • a thermoplastic material such as polypropylene, a polyethylene terephthalate, a polyethylene, etc.
  • the product A released pushes the product B through a movable piston. This prevents products A and B from being kept in contact with each other, which may be essential for certain pairs of products.
  • the respective flow rates are determined at least in part, by a separate part of the body of the dispensing head, which part also ensures the tight assembly of the assembly on the hollow rod (pump or valve for example).
  • This intermediate piece located between the container containing the first product and the reservoir containing the second product, makes it possible, if necessary, to considerably facilitate the molding of the body, and consequently to reduce the manufacturing cost thereof.
  • the same body can be used to dispense pairs of products with different respective flow rates, simply by changing the intermediate mounting part.
  • the intermediate part can also be obtained by molding, which molding is, in terms of cost, incommensurate with the additional cost which would be imposed on the manufacture of a head body mounted directly on the hollow rod and incorporating all the elements necessary for the distribution of the flows of product A in the head in order to modify the respective flow of each of the products.
  • the possibilities of adjusting the respective flow rates are much more numerous than those which would be possible if the flow distributor formed an integral part of the body of the distribution head, and this, only by playing on the configuration of the channels, passages or orifices formed by the intermediate piece.
  • the emptying of the device can be complete, whatever the ratio of the respective flow rates of each of the products.
  • the body can be surmounted by an element closing said body and forming a bearing surface to allow actuation pressure to be exerted, the outlet orifice (s) being carried by said element.
  • This element can be mounted by snapping, gluing, welding, or any other suitable means.

  • Product A can be pressurized by means of a liquefiable gas or not, or by means of a piston pushed by a gas for example.
  • the distribution member consists of a manually operated pump.
  • the product reservoir B can consist of an annular part of the body, the product A being conveyed to the second orifice via a central intake passage.
  • the body has a fixed annular bottom defining at least one orifice for placing the body in communication with the hollow rod, the reservoir comprising a movable bottom in the form of an annular piston capable of moving axially under the thrust of product A said movable bottom being axially separated from the fixed bottom.
  • the presence of the piston is not essential, in particular when it is a question of dispensing products of very pasty consistency.
  • the central intake passage can be raised relative to said fixed annular bottom and be carried by bridges of material spaced angularly around said orifice, and a first end of which is integral with the annular bottom, a second end being integral with the intake passage .
  • the intermediate part distributes the product A in the form of a central flow of product A, opening both directly into the central supply passage, and under the annular piston, between the fixed bottom and the annular piston.
  • the intermediate piece allows, by mounting on the hollow rod of small diameter, to allow the realization of a wider central passage.
  • the intermediate part comprises a part situated opposite the inlet orifice being able to form a deflector for the product A so as to convey it both in the central intake passage and under the annular piston via lateral passages located between bridges of material supporting the deflector.
  • the intermediate piece comprises a portion being capable of closing all or part of the orifice delimited by the fixed bottom, the product A being brought both into the passage of central supply and under the annular piston via lateral passages arranged between the fixed bottom and the intermediate piece, and opening into the body through orifices made in the fixed bottom, in the vicinity of the periphery of the body of the actuating means.
  • the intermediate part makes it possible to pass the product A at the periphery, under the annular piston.
  • This embodiment is advantageous in that it allows the evacuation of air, in particular in the case of a very viscous product A.
  • the portion capable of closing the central orifice can be carried by one or more bridges of material spaced angularly, so as to allow the passage of the product A in the lateral passages.
  • the reservoir for the second product B consists of a central part of the body, the first product A being conveyed to the second orifice via an annular supply passage surrounding all or part of the central reservoir.
  • the intermediate piece has an inlet opening in communication with the hollow rod which is arranged so as to distribute the product A in the form of a central flow intended to push the product B and passages lateral to generate first lateral flows for the supply of the annular supply passage, said first lateral flows opening into the annular supply passage through slots or orifices formed in an annular bottom of said supply passage. This reduces the central flow under product B, to increase the passage of product A through the annular zone.
  • Holes or slots may be provided in the central part of the body and opening onto the annular supply passage so as to generate second lateral flows to supply the annular supply passage. This increases the flow of product A leaving through the annular passage. Furthermore, upon priming, the piston evacuates the residual air located under it, through the slots or orifices in the central passage.
  • the actuating means are mounted on a covering hoop.
  • the covering band can be molded with the intermediate piece.
  • the hoop and the actuation means are formed in a single piece obtained from molding, said hoop being connected to the actuation means by bridges of frangible material.

  • the first and second ports can lead to a single outlet, or to two separate outlet.
  • this can be closed by an elastically deformable member, capable of moving away under the pressure of the product so as to release said outlet orifice and allow the outlet of the product, and return to the closed position when the pressure stops.
  • a lip made of elastomeric material is used.
  • the B / A flow rate ratio varies depending on the products and applications. For example, the ratio of B / A flow rates varies between 5/95 and 50/50.
  • the intermediate piece is mounted on the hollow rod via a sleeve, the hollow rod or the sleeve having, over at least part of the height of its external surface or its internal surface, ridges capable of allowing the evacuation of air. .

Under the product pressure, the lip 29 moves away from the seat 30 to let the product pass. When the pressure ceases, the lip 29 returns to seal against the rigid seat 30.
  • the annular zone 15 is closed by a movable bottom forming a piston 31, capable, under the pressure of the product A, of pushing the product B in the direction of the orifice 24.

Description

La présente invention a trait un dispositif pour la distribution simultanée de deux produits conditionnés séparément selon le préambule de la revendication 1. L'invention est tout particulièrement adaptée à l'application de certains produits utilisés en cosmétique, en pharmacie ou en dermato-pharmacologie. L'invention vise en particulier des produits qui, pour des raisons de stabilité ne peuvent être mis l'un au contact de l'autre, qu'au moment de l'utilisation. A titre d'exemple, on peut citer des actifs tels que la vitamine C, A, ou E, du bicarbonate, des acides de fruits tel que l'acide citrique, à distribuer avec un produit hydratant sous forme d'un gel, d'une crème ou d'un gel crème.The present invention relates to a device for the simultaneous distribution of two products packaged separately according to the preamble of claim 1. The invention is particularly suitable for the application of certain products used in cosmetics, pharmacy or dermato-pharmacology. The invention relates in particular to products which, for reasons of stability cannot be brought into contact with each other, until the time of use. By way of example, there may be mentioned active agents such as vitamin C, A, or E, bicarbonate, fruit acids such as citric acid, to be distributed with a moisturizing product in the form of a gel, d 'a cream or cream gel.

Le brevet FR-A-2 615 826 décrit un dispositif pour la distribution d'un mélange de substance pâteuse et d'au moins un additif pâteux, notamment sous forme d'un cordon strié. Le dispositif comprend un récipient, notamment un tube à parois souples, contenant un premier produit pâteux. Le récipient est surmonté d'un col sur lequel est montée une tête de distribution. La tête de distribution présente un corps dont une partie annulaire forme un réservoir pour un second produit, apte à sortir au travers d'un orifice de sortie, sous la poussée du premier produit. Le corps définit également un passage central pour acheminer le premier produit vers ledit orifice de sortie, de manière à former un cordon strié comportant un peu des deux produits. Selon une variante illustrée dans ce document, le second produit est contenu dans une partie centrale du corps de la tête de distribution, le premier produit étant quant à lui acheminé par un passage annulaire. Les débits respectifs de chacun des produits sont déterminés dans une large mesure par le diamètre du col du récipient à parois souples, et par la configuration du corps de la tête de distribution, etc.. Ainsi, si l'on souhaite produire un tel système, avec des caractéristiques de débits différents, cela implique de changer le corps de la tête de distribution, et donc d'investir dans un moule coûteux. Certes, dans un des modes de réalisation le corps contenant le second produit, présente un fond rapporté. Toutefois, la configuration du fond est telle que celui-ci ne modifie en rien le flux de produit sortant du tube à parois souples. Il n'a donc aucun impact sur les débits respectifs de chacun des produits.Patent FR-A-2 615 826 describes a device for the distribution of a mixture of pasty substance and at least one pasty additive, in particular in the form of a striated bead. The device comprises a container, in particular a tube with flexible walls, containing a first pasty product. The container is surmounted by a neck on which a dispensing head is mounted. The dispensing head has a body, an annular part of which forms a reservoir for a second product, capable of exiting through an outlet orifice, under the pressure of the first product. The body also defines a central passage for conveying the first product to said outlet orifice, so as to form a ridged bead comprising a little of the two products. According to a variant illustrated in this document, the second product is contained in a central part of the body of the dispensing head, the first product being in turn conveyed by an annular passage. The respective flow rates of each of the products are determined to a large extent by the diameter of the neck of the container with flexible walls, and by the configuration of the body of the dispensing head, etc. Thus, if one wishes to produce such a system , with different flow characteristics, this involves changing the body of the dispensing head, and therefore investing in an expensive mold. Admittedly, in one of the embodiments, the body containing the second product has an added bottom. However, the configuration of the bottom is such that it does not in any way modify the flow of product leaving the flexible-walled tube. It therefore has no impact on the respective flow rates of each product.

Dans le brevet FR 2 629 058, est décrit un dispositif du même type comprenant en outre des moyens pour faire varier les débits respectifs de chacun des produits. Typiquement, les débits sont ajustés en sortie du dispositif, en faisant varier la position angulaire d'un bec distributeur par rapport à une capsule, ce qui a pour effet de modifier en conséquence la section d'orifices au travers desquels sortent les produits. Un tel dispositif présente l'inconvénient d'être relativement complexe et coûteux à fabriquer.In patent FR 2 629 058, a device of the same type is described, further comprising means for varying the respective flow rates of each of the products. Typically, the flow rates are adjusted at the outlet of the device, by varying the angular position of a dispensing spout relative to a capsule, which has the effect of consequently modifying the section of orifices through which the products exit. Such a device has the drawback of being relatively complex and costly to manufacture.

Dans l'un des modes de réalisation du brevet EP 0 410 858, il est décrit un système équivalent dans lequel la fermeture de l'orifice de sortie est réalisée au moyen d'un organe élastiquement déformable, sous forme d'une lèvre, apte à s'écarter sous la pression du produit pour laisser passer le produit, et à revenir en position de fermeture, avec ou sans reprise d'air, dès que cesse la pression.In one of the embodiments of patent EP 0 410 858, an equivalent system is described in which the closure of the outlet orifice is carried out by means of an elastically deformable member, in the form of a lip, suitable to move away under the pressure of the product to let the product pass, and to return to the closed position, with or without air intake, as soon as the pressure ceases.

Un dispositif comportant les caractéristiques du préambule de la revendication 1 est connu du document EP-A-0 737 629.A device comprising the characteristics of the preamble of claim 1 is known from document EP-A-0 737 629.

Aussi, est-ce un des objets de l'invention que de fournir un dispositif pour la distribution de deux produits conditionnés séparément, présentant des moyens simples et économiques à réaliser, pour déterminer les débits respectifs de chacun des produits.It is therefore one of the objects of the invention to provide a device for the distribution of two products packaged separately, presenting simple and economical means to produce, for determining the respective flow rates of each of the products.

C'est en particulier un objet de l'invention que de réaliser un dispositif pour la distribution de deux produits conditionnés séparément, et dont le réglage des débits respectifs de chacun des produits, ne nécessite pas de changer la totalité de la tête de distribution.It is in particular an object of the invention to produce a device for the distribution of two products packaged separately, and the adjustment of the respective flow rates of each of the products, does not require changing the entire dispensing head.

C'est un autre objet de l'invention que de pouvoir utiliser une tête de distribution comprenant un corps obtenu de moulage d'un matériau thermoplastique notamment, et dont la modification des débits de sortie respectifs des produits n'implique pas de modification du corps de la tête de distribution.It is another object of the invention to be able to use a dispensing head comprising a body obtained from molding of a thermoplastic material in particular, and the modification of the respective output flow rates of the products does not imply modification of the body of the distribution head.

C'est encore un autre objet de l'invention que de réaliser un dispositif adaptable sur un récipient dont la sortie du produit est commandée par une pompe à actionnement manuel ou par une valve, via une tige de sortie dont le diamètre extérieur est très faible (typiquement inférieure à 5 mm, et généralement, de l'ordre de 2 à 3 mm).It is yet another object of the invention to provide a device which can be adapted to a container whose output of the product is controlled by a manual actuation or by a valve, via an outlet rod whose external diameter is very small (typically less than 5 mm, and generally, of the order of 2 to 3 mm).

D'autres objets encore apparaîtront de manière détaillée dans la description qui suit.Still other objects will appear in detail in the description which follows.

Ainsi, selon l'invention, ces objets sont atteints en réalisant un ensemble pour la distribution d'au moins deux produits conditionnés séparément, au travers d'au moins un orifice de sortie comprenant :

  • a) un premier récipient contenant un premier produit A;
  • b) un organe de distribution pour permettre la sortie sous pression du produit A, via une tige creuse montée sur des moyens de rappel élastiques, et dont une extrémité débouche hors du premier récipient;
  • c) des moyens surmontant l'organe de distribution, pour permettre l'actionnement de l'organe de distribution, lesdits moyens comportant un corps d'axe X, formant d'une part un réservoir pour le second produit B, apte à sortir au travers d'un premier orifice, sous la poussée du produit A sorti, et d'autre part, au moins un passage en communication avec la tige creuse pour acheminer le produit A sous pression, vers un second orifice;
   caractérisé en ce que lesdits moyens d'actionnement sont montés sur la tige creuse via une pièce intermédiaire comportant un orifice d'entrée en communication avec la tige creuse, ladite pièce intermédiaire étant apte, en coopération avec le corps, à répartir le produit A sous forme d'au moins un flux de produit A dont la configuration détermine les débits respectifs de sortie des produits A et B.Thus, according to the invention, these objects are achieved by producing an assembly for the distribution of at least two products packaged separately, through at least one outlet orifice comprising:
  • a) a first container containing a first product A;
  • b) a dispensing member to allow the pressurized outlet of product A, via a hollow rod mounted on elastic return means, and one end of which opens out of the first container;
  • c) means surmounting the dispensing member, to allow actuation of the dispensing member, said means comprising an axis X body, forming on the one hand a reservoir for the second product B, capable of leaving through a first orifice, under the thrust of the product A out, and on the other hand, at least one passage in communication with the hollow rod for conveying the product A under pressure, to a second orifice;
characterized in that said actuating means are mounted on the hollow rod via an intermediate piece comprising an entry orifice in communication with the hollow rod, said intermediate piece being capable, in cooperation with the body, of distributing the product A under forms at least one product A flow, the configuration of which determines the respective output flows of products A and B.

Avantageusement, le corps est constitué d'une seule pièce obtenue de moulage, notamment d'un matériau thermoplastique tel qu'un polypropylène, un polyéthylène téréphtalate, un polyéthylène, etc.. Avantageusement encore, le produit A sorti pousse le produit B au travers d'un piston mobile. Cela évite que les produits A et B soient conservés au contact l'un de l'autre, ce qui peut être indispensable pour certains couples de produits.Advantageously, the body consists of a single piece obtained from molding, in particular of a thermoplastic material such as polypropylene, a polyethylene terephthalate, a polyethylene, etc. Advantageously still, the product A released pushes the product B through a movable piston. This prevents products A and B from being kept in contact with each other, which may be essential for certain pairs of products.

Ainsi selon l'invention, les débits respectifs sont déterminés au moins en partie, par une pièce distincte du corps de la tête de distribution, laquelle pièce assure en outre le montage étanche de l'ensemble sur la tige creuse (de pompe ou de valve par exemple). Cette pièce intermédiaire, située entre le récipient contenant le premier produit et le réservoir contenant le second produit, permet, le cas échéant, de faciliter de manière considérable le moulage du corps, et en conséquence d'en réduire le coût de fabrication. En d'autres termes, le même corps peut être utilisé pour distribuer des couples de produits avec des débits respectifs différents, simplement en changeant la pièce intermédiaire de montage. La pièce intermédiaire peut également être obtenue de moulage, lequel moulage est, en termes de coût, sans commune mesure avec le surcoût qui serait imposé à la fabrication d'un corps de tête monté directement sur la tige creuse et incorporant tous les éléments nécessaires à la répartition des flux du produit A dans la tête afin de modifier le débit respectif de chacun des produits. En outre, les possibilités d'ajustement des débits respectifs sont nettement plus nombreuses que celles qui seraient possibles si le répartiteur de flux formait partie intégrante du corps de la tête de distribution, et ceci, seulement en jouant sur la configuration des canaux, passages ou orifices formés par la pièce intermédiaire.Thus according to the invention, the respective flow rates are determined at least in part, by a separate part of the body of the dispensing head, which part also ensures the tight assembly of the assembly on the hollow rod (pump or valve for example). This intermediate piece, located between the container containing the first product and the reservoir containing the second product, makes it possible, if necessary, to considerably facilitate the molding of the body, and consequently to reduce the manufacturing cost thereof. In other words, the same body can be used to dispense pairs of products with different respective flow rates, simply by changing the intermediate mounting part. The intermediate part can also be obtained by molding, which molding is, in terms of cost, incommensurate with the additional cost which would be imposed on the manufacture of a head body mounted directly on the hollow rod and incorporating all the elements necessary for the distribution of the flows of product A in the head in order to modify the respective flow of each of the products. In addition, the possibilities of adjusting the respective flow rates are much more numerous than those which would be possible if the flow distributor formed an integral part of the body of the distribution head, and this, only by playing on the configuration of the channels, passages or orifices formed by the intermediate piece.

Par ailleurs, la vidange du dispositif peut être complète, quel que soit le rapport des débits respectifs de chacun des produits.Furthermore, the emptying of the device can be complete, whatever the ratio of the respective flow rates of each of the products.

Avantageusement, le corps peut être surmonté d'un élément fermant ledit corps et formant une surface d'appui pour permettre d'exercer une pression d'actionnement, le (ou les) orifice(s) de sortie étant porté(s) par ledit élément. Cet élément peut être monté par claquage, collage, soudure, ou tout autre moyen approprié.Advantageously, the body can be surmounted by an element closing said body and forming a bearing surface to allow actuation pressure to be exerted, the outlet orifice (s) being carried by said element. This element can be mounted by snapping, gluing, welding, or any other suitable means.

Selon un premier mode de réalisation, le produit A est pressurisé dans le premier récipient, ledit organe de distribution étant formé d'une valve. Le produit A peut être pressurisé au moyen d'un gaz liquéfiable ou non, ou au moyen d'un piston poussé par un gaz par exemple. Alternativement, l'organe de distribution est constitué d'une pompe à actionnement manuel.According to a first embodiment, the product A is pressurized in the first container, said dispensing member being formed of a valve. Product A can be pressurized by means of a liquefiable gas or not, or by means of a piston pushed by a gas for example. Alternatively, the distribution member consists of a manually operated pump.

Le réservoir de produit B peut être constitué d'une partie annulaire du corps, le produit A étant acheminé vers le second orifice via un passage d'amenée central.The product reservoir B can consist of an annular part of the body, the product A being conveyed to the second orifice via a central intake passage.

Avantageusement, le corps comporte un fond annulaire fixe délimitant au moins un orifice pour la mise en communication du corps avec la tige creuse, le réservoir comportant un fond mobile sous forme d'un piston annulaire apte à se déplacer axialement sous la poussée du produit A sorti ledit fond mobile étant séparé axialement du fond fixe. La présence du piston n'est pas indispensable, en particulier lorsqu'il s'agit de distribuer des produits de consistance très pâteuse.Advantageously, the body has a fixed annular bottom defining at least one orifice for placing the body in communication with the hollow rod, the reservoir comprising a movable bottom in the form of an annular piston capable of moving axially under the thrust of product A said movable bottom being axially separated from the fixed bottom. The presence of the piston is not essential, in particular when it is a question of dispensing products of very pasty consistency.

Le passage d'amenée central peut être surélevé par rapport audit fond annulaire fixe et être porté par des ponts de matière espacés angulairement autour dudit orifice, et dont une première extrémité est solidaire du fond annulaire, une seconde extrémité étant solidaire du passage d'amenée.The central intake passage can be raised relative to said fixed annular bottom and be carried by bridges of material spaced angularly around said orifice, and a first end of which is integral with the annular bottom, a second end being integral with the intake passage .

Selon une première forme de réalisation, la pièce intermédiaire répartit le produit A sous forme d'un flux central de produit A, débouchant à la fois directement dans le passage d'amenée central, et sous le piston annulaire, entre le fond fixe et le piston annulaire. Ainsi dans ce mode de réalisation, la pièce intermédiaire permet, en assurant le montage sur la tige creuse de petit diamètre, d'autoriser la réalisation d'un passage central plus large. En outre, avec ce mode de réalisation, on peut utiliser le produit A sortant directement du récipient dans lequel il est conditionné.According to a first embodiment, the intermediate part distributes the product A in the form of a central flow of product A, opening both directly into the central supply passage, and under the annular piston, between the fixed bottom and the annular piston. Thus in this embodiment, the intermediate piece allows, by mounting on the hollow rod of small diameter, to allow the realization of a wider central passage. In addition, with this embodiment, it is possible to use the product A leaving directly from the container in which it is packaged.

Selon une seconde forme de réalisation, la pièce intermédiaire comporte une partie située en regard de l'orifice d'entrée étant apte à former un déflecteur pour le produit A de manière à l'acheminer à la fois dans le passage d'amenée central et sous le piston annulaire via des passages latéraux situés entre des ponts de matière supportant le déflecteur. On régule ainsi à la fois le flux de produit A passant dans le canal central et le flux de produit A poussant le piston annulaire. En outre comme pour le mode de réalisation précédent, cela permet d'élargir le passage central. Des orifices ou fentes peuvent être prévus à la base de la cheminée centrale, lesquels orifices peuvent, en début d'utilisation du dispositif être situés en regard du piston, mais qui seront dégagés après une légère remontée du piston, permettant ainsi d'augmenter le flux dans le passage d'amenée central.According to a second embodiment, the intermediate part comprises a part situated opposite the inlet orifice being able to form a deflector for the product A so as to convey it both in the central intake passage and under the annular piston via lateral passages located between bridges of material supporting the deflector. This regulates both the flow of product A passing through the central channel and the flow of product A pushing the annular piston. In addition, as for the previous embodiment, this makes it possible to widen the central passage. Holes or slots may be provided at the base of the central chimney, which orifices may, at the start of use of the device, be located opposite the piston, but which will be released after a slight rise in the piston, thereby increasing the flow in the central intake passage.

Un autre type de régulation est obtenu avec un mode de réalisation dans lequel la pièce intermédiaire comporte une portion étant apte à obturer en tout ou partie l'orifice délimité par le fond fixe, le produit A étant amené à la fois dans le passage d'amenée central et sous le piston annulaire via des passages latéraux disposés entre le fond fixe et la pièce intermédiaire, et débouchant dans le corps au travers d'orifices réalisés dans le fond fixe, au voisinage de la périphérie du corps des moyens d'actionnement. Outre l'élargissement du passage central, la pièce intermédiaire selon ce mode de réalisation, permet de faire passer le produit A en périphérie, sous le piston annulaire. Ce mode de réalisation est avantageux en ce qu'il permet l'évacuation d'air, notamment dans le cas d'un produit A très visqueux.Another type of regulation is obtained with an embodiment in which the intermediate piece comprises a portion being capable of closing all or part of the orifice delimited by the fixed bottom, the product A being brought both into the passage of central supply and under the annular piston via lateral passages arranged between the fixed bottom and the intermediate piece, and opening into the body through orifices made in the fixed bottom, in the vicinity of the periphery of the body of the actuating means. In addition to the widening of the central passage, the intermediate part according to this embodiment, makes it possible to pass the product A at the periphery, under the annular piston. This embodiment is advantageous in that it allows the evacuation of air, in particular in the case of a very viscous product A.

La portion apte à obturer l'orifice central peut être portée par un ou plusieurs ponts de matière espacés angulairement, de manière à permettre le passage du produit A dans les passages latéraux.The portion capable of closing the central orifice can be carried by one or more bridges of material spaced angularly, so as to allow the passage of the product A in the lateral passages.

Alternativement, le réservoir pour le second produit B est constitué d'une partie centrale du corps, le premier produit A étant acheminé vers le second orifice via un passage d'amenée annulaire entourant tout ou partie du réservoir central.Alternatively, the reservoir for the second product B consists of a central part of the body, the first product A being conveyed to the second orifice via an annular supply passage surrounding all or part of the central reservoir.

Dans cette hypothèse, la pièce intermédiaire comporte un orifice d'entrée en communication avec la tige creuse qui est disposé de manière à répartir le produit A sous forme d'un flux central destiné à pousser le produit B et des passages latéraux pour générer des premiers flux latéraux pour l'alimentation du passage d'amenée annulaire, lesdits premier flux latéraux débouchant dans le passage d'amenée annulaire au travers de fentes ou orifices ménagés dans un fond annulaire dudit passage d'amenée. On réduit ainsi le débit central sous le produit B, pour augmenter le passage du produit A par la zone annulaire.In this case, the intermediate piece has an inlet opening in communication with the hollow rod which is arranged so as to distribute the product A in the form of a central flow intended to push the product B and passages lateral to generate first lateral flows for the supply of the annular supply passage, said first lateral flows opening into the annular supply passage through slots or orifices formed in an annular bottom of said supply passage. This reduces the central flow under product B, to increase the passage of product A through the annular zone.

Des orifices ou fentes peuvent être ménagés dans la partie centrale du corps et débouchant sur le passage d'amenée annulaire de manière à générer des seconds flux latéraux pour alimenter le passage d'amenée annulaire. On augmente ainsi le flux de produit A sortant par le passage annulaire. Par ailleurs, à l'amorçage, le piston évacue l'air résiduel situé sous celui-ci, par les fentes ou orifices du passage central.Holes or slots may be provided in the central part of the body and opening onto the annular supply passage so as to generate second lateral flows to supply the annular supply passage. This increases the flow of product A leaving through the annular passage. Furthermore, upon priming, the piston evacuates the residual air located under it, through the slots or orifices in the central passage.

Avantageusement, les moyens d'actionnement sont montés sur une frette d'habillage. La frette d'habillage peut être venue de moulage avec la pièce intermédiaire.Advantageously, the actuating means are mounted on a covering hoop. The covering band can be molded with the intermediate piece.

Selon un autre mode de réalisation encore, la frette et les moyens d'actionnement sont formés d'une seule pièce obtenue de moulage, ladite frette étant reliée aux moyens d'actionnement par des ponts de matière frangibles. Les ponts de matière peuvent être cassés lors de la première utilisation, ce qui assure l'inviolabilité du système.According to yet another embodiment, the hoop and the actuation means are formed in a single piece obtained from molding, said hoop being connected to the actuation means by bridges of frangible material. The material bridges can be broken during the first use, which ensures the inviolability of the system.

Le produit A peut être contenu dans une poche en matériau souple. A titre d'exemple, on utilise une feuille d'aluminium, ou un complexe de plusieurs matériaux différents. Avantageusement, la poche est contenue à l'intérieur d'une enceinte rigide ou semi rigide.Product A can be contained in a pocket made of flexible material. By way of example, an aluminum sheet or a complex of several different materials is used. Advantageously, the pocket is contained inside a rigid or semi-rigid enclosure.

Les premier et second orifices peuvent déboucher sur un orifice de sortie unique, ou sur deux orifices de sortie distincts.The first and second ports can lead to a single outlet, or to two separate outlet.

Notamment dans l'hypothèse d'un orifice de sortie unique, celui-ci peut être obturé par un organe élastiquement déformable, apte à s'écarter sous la pression du produit de manière à dégager ledit orifice de sortie et permettre la sortie du produit, et à revenir en position d'obturation lorsque cesse la pression. Avantageusement on utilise une lèvre en matériau élastomérique.In particular in the case of a single outlet orifice, this can be closed by an elastically deformable member, capable of moving away under the pressure of the product so as to release said outlet orifice and allow the outlet of the product, and return to the closed position when the pressure stops. Advantageously, a lip made of elastomeric material is used.

Le rapport des débits B/A varie en fonction des produits et des applications. A titre d'exemple, le rapport des débits B/A varie entre 5/95 et 50/50.The B / A flow rate ratio varies depending on the products and applications. For example, the ratio of B / A flow rates varies between 5/95 and 50/50.

Avantageusement, la pièce intermédiaire est montée sur la tige creuse via un manchon, la tige creuse ou le manchon présentant sur au moins une partie de la hauteur de sa surface extérieure ou sa surface interne, des stries aptes à permettre l'évacuation d'air. Cette fonction d'évacuation de l'air est tout particulièrement avantageuse lorsque la tête de distribution est amovible.Advantageously, the intermediate piece is mounted on the hollow rod via a sleeve, the hollow rod or the sleeve having, over at least part of the height of its external surface or its internal surface, ridges capable of allowing the evacuation of air. . This air evacuation function is particularly advantageous when the dispensing head is removable.

Selon un mode de réalisation préféré, les moyens d'actionnement sont montés en force sur la pièce intermédiaire. D'autres moyens encore peuvent être utilisés pour le montage des moyens d'actionnement sur la pièce intermédiaire.According to a preferred embodiment, the actuating means are force-fitted to the intermediate piece. Still other means can be used for mounting the actuating means on the intermediate piece.

A titre d'exemple, les produits A et B sont des compositions cosmétiques, pharmaceutiques, ou dermato-pharmaceutiques.By way of example, products A and B are cosmetic, pharmaceutical or dermato-pharmaceutical compositions.

Un bord libre de la poche est monté par collage ou soudure sur une tête de poche 3, laquelle est montée sur le bord libre d'une enceinte rigide ou semi rigide 4, présentant en son fond un orifice de reprise d'air 5. La tête de poche 3 présente une jupe annulaire 6 fermée par un fond annulaire 7, portant une cheminée centrale 8 en communication avec la poche, et sur laquelle est montée une pompe à actionnement manuel 9. La pompe 9 peut être montée par sertissage, via une pièce intermédiaire (non représentée) qui peut être claquée à l'intérieur de la cheminée centrale 8.

The pump 9 can be mounted by crimping, via a intermediate piece (not shown) which can be slammed inside the central chimney 8. The annular skirt 6 has on its outer surface, an annular edge 10 intended to come to bear on the free edge of the rigid or semi enclosure rigid 4, the skirt 6 being forcibly inserted into the opening of the enclosure 4.

Une tête de distribution 13 est montée sur la tige de pompe 11 au moyen d'un élément intermédiaire 32 dont la fonction et les caractéristiques seront décrites plus en détail par la suite. La tête de distribution comprend un corps 14 d'axe X, obtenu de moulage d'une seule pièce, en polypropylène par exemple. Le corps 14 délimite une zone annulaire 15, contenant un second produit B, par exemple un actif, à distribuer en combinaison avec le produit contenu dans la poche 2. Le produit B peut être constitué d'un produit en phase anhydre, d'une crème ou d'un gel, contenant des actifs tels que la vitamine C, A ou E, du bicarbonate ou des acides de fruits.A dispensing head 13 is mounted on the pump rod 11 by means of an intermediate element 32 whose function and characteristics will be described in more detail below. The dispensing head comprises a body 14 of axis X, obtained by molding in one piece, in polypropylene for example. The body 14 delimits an annular zone 15, containing a second product B, for example an active ingredient, to be distributed in combination with the product contained in the bag 2. The product B can consist of a product in the anhydrous phase, a cream or gel, containing active ingredients such as vitamin C, A or E, bicarbonate or fruit acids.

Le corps 14 présente un fond annulaire fixe 16 délimitant une ouverture axiale 17. Une cheminée centrale 18 est portée par trois pattes 19 disposées régulièrement autour de l'orifice 17, de manière à permettre le passage du premier produit A entre lesdites pattes 19.The body 14 has a fixed annular bottom 16 delimiting an axial opening 17. A central chimney 18 is carried by three legs 19 arranged regularly around the orifice 17, so as to allow the passage of the first product A between said tabs 19.

Un capuchon 20 est disposé de manière à fermer le corps 14 et à définir une surface d'appui 21 pour permettre l'actionnement de la pompe 9. Le capuchon est monté par claquage sur le bord libre du corps 14. La cheminée centrale 18 est de hauteur axiale telle que, en position montée du capuchon 20, la cheminée centrale soit en contact avec la surface interne de la paroi transversale 27 du capuchon formant la surface d'appui 21. Un organe élastomérique 22 est disposé à l'intérieur du capuchon, et définit avec le corps du capuchon, un passage axial 23 en communication avec la zone annulaire 15 via une fente ou un orifice 24 ménagé dans une paroi transversale 28 du capuchon, ledit passage axial 23 débouchant sur un passage radial 25, en communication également avec la cheminée centrale 18 via une fente ou un orifice 26 ménagé dans la paroi de la cheminée centrale 18, au voisinage de son bord supérieur. Le passage radial 25 débouche sur un bec au niveau duquel, l'organe élastomérique forme une lèvre 29. En position de repos, la lèvre 29 est en appui élastique sur un bord correspondant formé par la paroi transversale 27 du bouchon 20, ledit bord formant un siège 30 pour ladite lèvre 29. Sous la pression de produit, la lèvre 29 s'écarte du siège 30 pour laisser passer le produit. Lorsque cesse la pression, la lèvre 29 revient en appui étanche contre le siège rigide 30.A cap 20 is arranged so as to close the body 14 and to define a bearing surface 21 to allow actuation of the pump 9. The cap is mounted by snapping on the free edge of the body 14. The central chimney 18 is of axial height such that, in the mounted position of the cap 20, the central chimney is in contact with the internal surface of the transverse wall 27 of the cap forming the bearing surface 21. An elastomeric member 22 is disposed inside the cap , and defines with the body of the cap, an axial passage 23 in communication with the annular zone 15 via a slot or an orifice 24 formed in a transverse wall 28 of the cap, said axial passage 23 opening onto a radial passage 25, also in communication with the central chimney 18 via a slot or an orifice 26 formed in the wall of the central chimney 18, in the vicinity of its upper edge. The radial passage 25 opens onto a spout at which the elastomeric member forms a lip 29. In the rest position, the lip 29 is in elastic support on a corresponding edge formed by the transverse wall 27 of the plug 20, said edge forming a seat 30 for said lip 29. Under the product pressure, the lip 29 moves away from the seat 30 to let the product pass. When the pressure ceases, the lip 29 returns to seal against the rigid seat 30.

La zone annulaire 15 est fermée par un fond mobile formant un piston 31, apte, sous la poussée du produit A, à pousser le produit B en direction de l'orifice 24. Le piston annulaire 31 est séparé axialement du fond 16, de manière à permettre au produit A de passer dans l'espace annulaire compris entre le fond fixe 16 et le piston, afin de pousser ce dernier. La tête de distribution 13 est montée sur la tige de pompe 11, via un élément intermédiaire 32, jouant en outre la fonction de répartiteur de flux. L'élément intermédiaire 32 comprend une paroi transversale 39 reliée à un bord annulaire 40, de diamètre externe légèrement inférieur au diamètre interne du bord libre du corps 14, de manière à permettre un montage en force du corps 14 sur l'élément intermédiaire 32. L'élément intermédiaire porte en son centre une cheminée axiale 33 formant un manchon de diamètre intérieur apte à permettre son montage en force sur la tige de pompe 11. La cheminée axiale 33 débouche sur un orifice 34, en communication avec la tige creuse 11, et débouchant en regard de l'orifice central 17 délimité par le fond fixe 16.The annular zone 15 is closed by a movable bottom forming a piston 31, capable, under the pressure of the product A, of pushing the product B in the direction of the orifice 24. The annular piston 31 is separated axially from the bottom 16, so allowing product A to pass into the annular space between the fixed bottom 16 and the piston, in order to push the latter. The dispensing head 13 is mounted on the pump rod 11, via an intermediate element 32, further playing the function of flow distributor. The intermediate element 32 comprises a transverse wall 39 connected to an annular edge 40, of external diameter slightly less than the internal diameter of the free edge of the body 14, so as to allow a force mounting of the body 14 on the intermediate element 32. The intermediate element carries in its center an axial chimney 33 forming an inner diameter sleeve capable of allowing it to be mounted in force on the pump rod 11. The axial chimney 33 opens onto an orifice 34, in communication with the hollow rod 11, and opens out opposite the central hole 17 delimited by the fixed bottom 16.

Un capot amovible 36 recouvre la tête de distribution. La tête de distribution comprend également une frette d'habillage 42. Dans ce mode de réalisation, la frette 42 est obtenue de moulage avec le corps 14 de la tête de distribution 13. La frette 42 est montée par claquage sur la tête de poche 3. A la sortie du moule, la frette est reliée au corps par des pattes sécables 43, notamment lors de la première utilisation, garantissant l'inviolabilité de l'ensemble avant sa première utilisation.A removable cover 36 covers the dispensing head. The dispensing head also comprises a covering hoop 42. In this embodiment, the hoop 42 is obtained by molding with the body 14 of the dispensing head 13. The hoop 42 is mounted by snap-fastening on the pocket head 3 On leaving the mold, the hoop is connected to the body by breakable tabs 43, in particular during the first use, guaranteeing the inviolability of the assembly before its first use.

Pour distribuer le mélange, l'utilisatrice appuie sur la surface d'appui 21 du bouton poussoir 13, ce qui provoque l'enfoncement de la tige de pompe 11 et la sortie du produit A, au travers de la tige creuse, via l'orifice 34 de l'élément intermédiaire 32. Le produit A passe, au travers des pattes 19 sous le piston 31, ce qui sous la pression, provoque la sortie du produit B au travers de l'orifice 24 et du passage 23. Le produit B est ainsi acheminé dans le passage radial 25. Simultanément, le produit A passe dans la cheminée centrale 18 et débouche dans le canal radial 25, où il se mélange au produit B. La poussée du mélange provoque l'ouverture de la lèvre 29, ledit mélange sortant au niveau de l'orifice de sortie 35 délimité par la lèvre et le siège. En relâchant la pression sur le bouton poussoir 13, la tige de pompe revient en position fermée par rappel élastique, ce qui interrompt la sortie des produits A et B.To dispense the mixture, the user presses on the support surface 21 of the push button 13, which causes the pump rod 11 to sink and the product A to exit, through the hollow rod, via the orifice 34 of the intermediate element 32. The product A passes through the tabs 19 under the piston 31, which under pressure causes the product B to exit through the orifice 24 and the passage 23. The product B is thus routed in the radial passage 25. Simultaneously, the product A passes through the central chimney 18 and opens into the radial channel 25, where it mixes with the product B. The thrust of the mixture causes the opening of the lip 29, said mixture leaving at the outlet orifice 35 delimited by the lip and the seat. By releasing the pressure on the push button 13, the pump rod returns to the closed position by elastic return, which interrupts the output of products A and B.

Alternativement, il est possible de prévoir deux passages 25 disposés côte à côte, et débouchant sur deux orifices adjacents, de manière à provoquer la sortie simultanée, mais séparée des deux produits A et B. Le ou les orifices peuvent déboucher latéralement comme dans le mode de réalisation illustré, ou parallèlement à l'axe du dispositif.Alternatively, it is possible to provide two passages 25 arranged side by side, and leading to two adjacent orifices, so as to cause the simultaneous but separate exit of the two products A and B. The orifice (s) can open laterally as in the mode illustrated embodiment, or parallel to the axis of the device.

Ainsi, dans cette version, la pièce intermédiaire utilisée pour assurer le montage de la tête de distribution sur la tige de pompe, permet, outre l'étanchéité, d'augmenter le débit de produit A passant directement dans le canal central 18, en permettant de donner à ce dernier une section plus large que celle qu'il pourrait avoir si le bouton poussoir était monté directement sur la tige de pompe, notamment en raison des impératifs de moulage et de démoulage. De la même manière, on diminue le flux de produit efficace pour pousser le piston 31 et faire sortir le produit B. On diminue ainsi le rapport des débits B/A. En outre, on diminue la fragilité de la cheminée centrale.Thus, in this version, the intermediate part used for mounting the dispensing head on the pump rod, allows, in addition to sealing, to increase the flow of product A passing directly into the central channel 18, allowing to give the latter a wider section than that which it could have if the push button was mounted directly on the pump rod, in particular due to the requirements of molding and demolding. In the same way, the effective product flow is reduced to push the piston 31 and let the product out B. This reduces the ratio of the flow rates B / A. In addition, the fragility of the central chimney is reduced.

Dans la variante de la figure 2A, l'élément intermédiaire 32 porte en regard de l'orifice 34, un déflecteur 37 porté par des pattes 38 espacées angulairement tout autour de l'orifice 34. Les flux de produit A sont illustrés sur le dessin par les flèches. Le déflecteur 37 brise le flux de produit A sortant de la tige de pompe et augmente le flux dudit produit A dirigé latéralement sous le piston, ce qui augmente la poussée appliquée au piston, et donc la quantité de produit B distribuée. On régule ainsi le flux de produit B à l'amorçage. Avantageusement, des orifices ou fentes 38, ménagés à la base de la cheminée centrale 18, et situés, avant la première utilisation, en regard du piston 31, sont dégagés, au fur et à mesure que le piston monte. Ces orifices, une fois dégagés, permettent en effet au produit A de passer depuis le passage annulaire vers le canal central 18, augmentant ainsi le débit de produit A dans le passage central 18. Dans ce mode de réalisation, la surface interne de la jupe axiale 33 porte des stries verticales 41 pour permettre l'évacuation de l'air lors du montage de la tête de distribution 13 sur la tige de pompe. Les stries 41 s'étendent sur toute la hauteur de la tige ou de la jupe axiale 33, à l'exception de l'extrémité supérieure, de manière à assurer une portée étanche de la jupe sur la tige creuse, sur environ 1 mm. De la même manière que pour le mode de réalisation précédent, on peut réaliser un canal d'amenée 18 de section plus ou moins large, en fonction du rapport de débit B/A souhaité.In the variant of FIG. 2A, the intermediate element 32 carries, opposite the orifice 34, a deflector 37 carried by tabs 38 angularly spaced around the orifice 34. The flows of product A are illustrated in the drawing by the arrows. The deflector 37 breaks the flow of product A leaving the pump rod and increases the flow of said product A directed laterally under the piston, which increases the thrust applied to the piston, and therefore the quantity of product B distributed. This regulates the flow of product B at the start. Advantageously, orifices or slots 38, formed at the base of the central chimney 18, and located, before the first use, facing the piston 31, are released, as the piston rises. These openings, once released, allow product A to pass from the annular passage to the central channel 18, thereby increasing the flow of product A in the central passage 18. In this embodiment, the internal surface of the skirt axial 33 carries vertical striations 41 to allow the evacuation of air during mounting of the dispensing head 13 on the pump rod. The ridges 41 extend over the entire height of the rod or of the axial skirt 33, with the exception of the upper end, so as to ensure a sealed bearing of the skirt on the hollow rod, over approximately 1 mm. In the same way as for the previous embodiment, it is possible to produce a supply channel 18 of more or less wide section, depending on the desired B / A flow ratio.

Dans la variante de la figure 2B, le fond fixe 16 du corps 14 est séparé axialement de la paroi transversale 39 de l'élément intermédiaire 32. Par ailleurs, l'orifice 17 est obturé de manière étanche par un élément d'obturation 44 porté par des pattes espacées angulairement 45. En outre, des passages ou orifices 46 sont ménagés dans le fond fixe 16, au voisinage de sa périphérie. Ainsi, le produit A sort de la tige creuse 11 via l'orifice 34 de l'élément intermédiaire 32, passe sous le fond fixe 16, débouche dans le corps 14 via les orifices ou fentes périphériques 46. Une fois dans le corps, le produit, d'une part, pousse le piston 31, et d'autre part, passe dans le canal central 18 entre les pattes 19. Cette configuration permet avantageusement d'évacuer l'air, en particulier à l'amorçage, notamment si le produit A est très visqueux.In the variant of FIG. 2B, the fixed bottom 16 of the body 14 is axially separated from the transverse wall 39 of the intermediate element 32. Furthermore, the orifice 17 is closed in leaktight fashion by a closure element 44 carried by legs spaced angularly 45. In addition, passages or orifices 46 are formed in the fixed bottom 16, in the vicinity of its periphery. Thus, the product A leaves the hollow rod 11 via the orifice 34 of the intermediate element 32, passes under the fixed bottom 16, opens into the body 14 via the orifices or peripheral slots 46. Once in the body, the product, on the one hand, pushes the piston 31, and on the other hand, passes through the central channel 18 between the lugs 19. This configuration advantageously makes it possible to evacuate the air, in particular when priming, in particular if the product A is very viscous.

La variante de la figure 2C diffère de la variante de la figure 2B, en ce que l'élément 44 n'obture pas intégralement l'orifice 17 du fond 16, de sorte qu'une partie du produit passe tout autour de l'élément 44 pour être acheminé dans le canal central 18, le reste du produit A passant sous le fond fixe 16 et débouche sous le piston 31 via les passages ou orifices périphériques 46. Ainsi, par rapport à la variante précédente, on augmente le débit de produit A dans le canal central 18. La quantité de produit passant dans l'espace annulaire situé tout autour de l'élément 44 dépend de la largeur de ce dernier. En jouant sur cette largeur, on joue en conséquence sur les débits respectifs de chacun des produits A et B.The variant of FIG. 2C differs from the variant of FIG. 2B in that the element 44 does not completely block the orifice 17 of the bottom 16, so that part of the product passes all around the element 44 to be conveyed in the central channel 18, the rest of the product A passing under the fixed bottom 16 and opens under the piston 31 via the peripheral passages or orifices 46. Thus, compared with the previous variant, the product flow is increased A in the central channel 18. The quantity of product passing through the annular space situated all around the element 44 depends on the width of the latter. By playing on this width, we play accordingly on the respective bit rates of each of the products A and B.

Dans la variante de la figure 2D, les flux de produit A sont sensiblement identiques aux flux de produit A dans la variante de la figure précédente. Toutefois, le fond fixe 16 du corps 14 à un profil présentant un renfoncement axial, similaire à celui formé par l'élément intermédiaire 32, réduisant ainsi l'espace axial présent entre l'élément intermédiaire 32 et le fond fixe 16, et augmentant la longueur du trajet du produit A sous le fond fixe 16. Le produit A sort de la tige creuse 11 via l'orifice 34 de l'élément intermédiaire 32, passe d'une part, dans la cheminée centrale 18, tout autour de l'élément 44, et d'autre part, sous le fond fixe 16, où il débouche dans le corps 14 via les orifices ou fentes périphériques 46. Une fois dans le corps, le produit, d'une part, pousse le piston 31, et d'autre part passe dans le canal central 18 via des orifices ou fentes 47 ménagés dans la partie inférieure de la cheminée centrale 18, au voisinage du fond fixe. Ainsi, une partie du produit A passe sensiblement en direct dans le canal d'amenée 18, tandis qu'une autre partie passe d'abord sous le piston 31 avant de passer dans le canal d'amenée 18. Comme on peut le voir, en jouant sur la taille, le nombre, la longueur des passages, et leur configuration, on modifie les débits respectifs des produits A et B. En réalité, le nombre de variantes est illimité et permet d'obtenir des ajustements très fins du rapport B/A.In the variant of FIG. 2D, the flows of product A are substantially identical to the flows of product A in the variant of the previous figure. However, the fixed bottom 16 of the body 14 has a profile having an axial recess, similar to that formed by the intermediate element 32, thus reducing the axial space present between the intermediate element 32 and the fixed bottom 16, and increasing the length of the path of the product A under the fixed bottom 16. The product A leaves the hollow rod 11 via the orifice 34 of the intermediate element 32, passes on the one hand, in the central chimney 18, all around the element 44, and on the other hand, under the fixed bottom 16, where it opens into the body 14 via the orifices or peripheral slots 46. Once in the body, the product, on the one hand, pushes the piston 31, and on the other hand passes into the central channel 18 via orifices or slots 47 formed in the lower part of the central chimney 18, in the vicinity of the fixed bottom. Thus, part of the product A passes substantially directly into the supply channel 18, while another part passes first under the piston 31 before passing into the supply channel 18. As can be seen, by varying the size, the number, the length of the passages, and their configuration, the respective flow rates of the products A and B are modified. In reality, the number of variants is unlimited and allows very fine adjustments to be made to the ratio B /AT.

Dans le mode de réalisation de la figure 3, le corps 114 de la tête de distribution 113 présente un passage central 118 dans lequel est disposé le produit B. Le passage central 118 a son fond obturé par un fond mobile 131 faisant office de piston. Le corps 114 définit une zone annulaire 115 destinée au passage du produit A. Le corps est fermé en sa partie supérieure par un capuchon 200 dont une surface inclinée 210 définit une surface d'appui pour l'actionnement d'une valve 105 surmontant un récipient 104 de type bidon aérosol, contenant le produit A. La valve est surmontée d'une tige de valve 103. Le capuchon 200 comporte deux canaux 250, 251, débouchant sur deux orifices de sortie adjacents 350, 351. Le premier canal 251 est en communication avec le canal central 118 via un orifice 126. Le second canal 250 est en communication avec la zone annulaire via un orifice 124. Les deux orifices de sortie 350, 351 sont situés de façon rapprochée l'un de l'autre de manière à faciliter le prélèvement simultané des deux produits distribués. La zone annulaire présente un fond annulaire fixe 116 percé d'une fente annulaire 146, ou d'une pluralité de fentes ou orifices disposés régulièrement sur la périphérie du fond 116. Une frette 142 est solidaire du corps et présente un bord libre 101 apte, lors de l'actionnement de la valve 105 à coulisser à l'intérieur d'une jupe 102 montée par claquage sur le bord du récipient 104. Le corps 114 de la tête de distribution 113 est monté sur la tige de valve 103 via un élément intermédiaire 132 agissant en outre comme répartiteur de flux du produit A, de manière à déterminer le rapport de débits B/A.In the embodiment of Figure 3, the body 114 of the dispensing head 113 has a central passage 118 in which is placed the product B. The central passage 118 has its bottom closed by a movable bottom 131 acting as a piston. The body 114 defines an annular zone 115 intended for the passage of the product A. The body is closed in its upper part by a cap 200 of which an inclined surface 210 defines a bearing surface for the actuation of a valve 105 surmounting a container 104 of aerosol can type, containing product A. The valve is surmounted by a valve stem 103. The cap 200 has two channels 250, 251, opening onto two adjacent outlet orifices 350, 351. The first channel 251 is in communication with the central channel 118 via an orifice 126. The second channel 250 is in communication with the annular zone via an orifice 124. The two outlet orifices 350, 351 are located in close proximity to one another so as to facilitate the simultaneous collection of the two products distributed. The annular zone has a fixed annular bottom 116 pierced with an annular slot 146, or with a plurality of slots or orifices regularly arranged on the periphery of the bottom 116. A hoop 142 is integral with the body and has a free edge 101 capable, during the actuation of the valve 105 to slide inside a skirt 102 mounted by snap on the edge of the container 104. The body 114 of the dispensing head 113 is mounted on the valve stem 103 via an element intermediate 132 also acting as a flow distributor for product A, so as to determine the flow rate ratio B / A.

Dans ce mode de réalisation, l'élément intermédiaire 132 comprend un plateau transversal 139 portant une jupe axiale 133 formant un manchon de diamètre approprié pour permettre son montage en force sur la tige de valve 103. La jupe axiale 133 débouche sur un orifice de sortie 134 disposé en regard du piston mobile 131. Le corps 114 de la tête de distribution 113 est monté à force sur l'élément intermédiaire 132, par l'intermédiaire d'une jupe latérale 140, coopérant de manière étanche avec la surface interne du bord libre du corps 114, ledit plateau 139 étant en contact avec le fond annulaire fixe 116. La surface supérieure du plateau transversal 139 présente des canaux 150 s'étendant radialement depuis l'orifice 134 jusqu'à la périphérie de l'élément 132 de manière à être en communication avec le passage annulaire 115 via les fentes ou orifices 146. Les canaux sont espacés régulièrement sur toute la surface de l'élément 132.In this embodiment, the intermediate element 132 comprises a transverse plate 139 carrying an axial skirt 133 forming a sleeve of suitable diameter to allow it to be mounted in force on the valve stem 103. The axial skirt 133 opens onto an outlet orifice 134 disposed opposite the movable piston 131. The body 114 of the dispensing head 113 is forcibly mounted on the intermediate element 132, by means of a side skirt 140, cooperating in leaktight manner with the internal surface of the edge free from the body 114, said plate 139 being in contact with the fixed annular bottom 116. The upper surface of the transverse plate 139 has channels 150 extending radially from the orifice 134 to the periphery of the element 132 so to be in communication with the annular passage 115 via the slots or orifices 146. The channels are evenly spaced over the entire surface of the element 132.

Pour utiliser l'ensemble en vue de la distribution simultanée des produits A et B, l'utilisatrice appuie sur la surface 210, provoquant l'enfoncement de la tige de valve 103. Le produit pressurisé sort via la tige creuse 103 et débouche dans le corps 114 de la tête de distribution 113 au travers de l'orifice 134 ménagé dans le plateau 139 de l'élément intermédiaire 132. Une première partie du produit A pousse le piston central 131 et provoque la sortie du produit B au travers de l'orifice de sortie 351. L'autre partie du produit A passe dans les canaux radiaux 150, sous le fond annulaire 116, et débouche dans le passage annulaire 115, via les fentes ou orifices 146. Le produit A sort de manière simultanée au produit B par l'orifice de sortie 350. Lorsque cesse la pression d'actionnement sur la surface 210, la tige de valve 103 revient par rappel élastique, en position de fermeture, ce qui interrompt la distribution des produits A et B.To use the assembly for the simultaneous distribution of products A and B, the user presses on the surface 210, causing the valve rod 103 to sink. The pressurized product leaves via the hollow rod 103 and opens into the body 114 of the dispensing head 113 through the orifice 134 formed in the plate 139 of the intermediate element 132. A first part of the product A pushes the central piston 131 and causes the product B to exit through the outlet orifice 351. The other part of the product A passes through the radial channels 150, under the annular bottom 116, and opens into the annular passage 115, via the slots or orifices 146. The product A leaves simultaneously with the product B through the outlet orifice 350. When the actuating pressure on the surface 210 ceases, the valve stem 103 returns by elastic return, in the closed position, which interrupts the distribution of the products A and B.

De la même manière que pour l'autre mode de réalisation, le montage de la tête de distribution 113 sur la tige de valve 103, via un élément intermédiaire 132 permet de choisir librement les sections respectives du canal central 118 et du passage annulaire 115, indépendamment de la section de la tige de valve 103. En outre, on ajuste le rapport des débits respectifs en jouant notamment sur les dimensions et le nombre de passages radiaux 150 et d'orifices 146.In the same way as for the other embodiment, the mounting of the dispensing head 113 on the valve stem 103, via an intermediate element 132 makes it possible to freely choose the respective sections of the central channel 118 and of the annular passage 115, regardless of the section of the valve stem 103. In in addition, the ratio of the respective flow rates is adjusted, in particular by varying the dimensions and the number of radial passages 150 and orifices 146.

Selon la variante des figures 4A et 4B, l'élément intermédiaire 132 se prolonge radialement par une jupe, obtenue de moulage avec l'élément 132, et formant une frette d'habillage 142. L'élément 132 est constitué de deux parties 153, 154, montées en force l'une sur l'autre. La première partie 153 comporte un plateau transversal annulaire 139 sur la surface extérieure duquel sont ménagés les canaux radiaux 150. Le bord extérieur du plateau annulaire 139 est relié à la frette 142 via un bord vertical 140 dont le diamètre externe est légèrement inférieur au diamètre interne du bord inférieur du corps 114, de manière à permettre un montage en force du corps 114 sur l'élément intermédiaire 132. Le bord interne du plateau annulaire 139 est relié à une portion centrale surélevée 151, via un bord 152 dont le diamètre externe est légèrement inférieur au diamètre interne du passage central 118 de manière à s'insérer en force dans ledit passage central. La portion centrale surélevée est percée en son centre d'un orifice 134. La pièce 153 est montée en force sur une seconde pièce 154 présentant en son centre un alésage pour être monté en force sur la tige de valve 103. Un espace 155 est prévu entre la pièce 152 et la pièce 153 de manière à former pour le produit une chambre d'expansion à la sortie de la valve 105.According to the variant of FIGS. 4A and 4B, the intermediate element 132 is extended radially by a skirt, obtained by molding with the element 132, and forming a covering hoop 142. The element 132 consists of two parts 153, 154, force-fitted one over the other. The first part 153 comprises an annular transverse plate 139 on the external surface of which the radial channels 150 are formed. The external edge of the annular plate 139 is connected to the hoop 142 via a vertical edge 140 whose external diameter is slightly less than the internal diameter from the lower edge of the body 114, so as to allow a force fitting of the body 114 on the intermediate element 132. The internal edge of the annular plate 139 is connected to a raised central portion 151, via an edge 152 whose external diameter is slightly smaller than the internal diameter of the central passage 118 so as to be forced into said central passage. The raised central portion is pierced in its center with an orifice 134. The part 153 is force-fitted on a second part 154 having in its center a bore to be force-fitted on the valve stem 103. A space 155 is provided between the part 152 and the part 153 so as to form for the product an expansion chamber at the outlet of the valve 105.

En actionnant la valve, le produit A sort de la tige de valve 103, et débouche dans la chambre d'expansion 155. Une partie du produit A sort sous le piston central 131 via l'orifice 134, de manière à pousser une quantité de produit B vers l'orifice de sortie 351. Une partie du produit A dirigé dans le passage central 118, passe dans la zone annulaire 115 au travers d'orifices ou de fentes 157 disposés dans la partie inférieure de la cheminée centrale 118. On crée ainsi deux niveaux de flux vers la zone annulaire. Les orifices 157 peuvent, avant la première utilisation être situés en regard du piston, et se dégager après que le piston ait remonté d'une certaine hauteur axiale. Simultanément, l'autre partie du produit A passe dans les canaux radiaux 150, entre la pièce intermédiaire 132 et le fond fixe 116, et débouche dans la zone annulaire 115 via les fentes ou orifices 146. Le produit A sort par l'orifice de sortie 350. De la même manière que pour les autres modes de réalisation, les possibilités d'ajustement sont infinies en jouant sur la taille, le nombre, et la configuration des passages, orifices ou autres éléments constituant l'élément intermédiaire 132.By actuating the valve, the product A leaves the valve stem 103, and opens into the expansion chamber 155. Part of the product A leaves under the central piston 131 via the orifice 134, so as to push a quantity of product B towards the outlet orifice 351. A part of the product A directed in the central passage 118, passes into the annular zone 115 through orifices or slots 157 arranged in the lower part of the central chimney 118. We create thus two levels of flow towards the annular zone. The orifices 157 may, before the first use, be located opposite the piston, and disengage after the piston has risen by a certain axial height. Simultaneously, the other part of the product A passes through the radial channels 150, between the intermediate part 132 and the fixed bottom 116, and opens into the annular zone 115 via the slots or orifices 146. The product A exits through the outlet port 350. In the same way as for the other embodiments, the possibilities of adjustment are endless by varying the size, the number, and the configuration of the passages, orifices or other elements constituting the intermediate element 132.

Dans tous ces modes de réalisation, les débits respectifs des produits A et B sont déterminés également dans une certaine mesure par la configuration des canaux de sortie des produits A et B. Ces canaux de sortie peuvent comporter à titre d'exemple des restrictions ou autres éléments aptes à modifier le flux des produits sortant.In all these embodiments, the respective flow rates of products A and B are also determined to a certain extent by the configuration of the outlet channels of products A and B. These outlet channels may include, for example, restrictions or the like. elements capable of modifying the flow of outgoing products.

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'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to preferred embodiments of the invention. It is obvious that variants can be made without departing from the invention as claimed below.
