  • Multi-channel valves are known EP 1 281 635 A1 and EP 2 024 256 A1 . These are valves that can collect as many products as there are ways without these products cross before leaving the valve. They are intended for products that must be separated during storage and must come into contact only when they are applied in order to prevent them from reacting together prematurely.
  • the diffusers intended for these multi-way valves make it possible to actuate the valve. They have exit channels that usually do not meet. This allows products to come into contact only once they have left the broadcaster. A single pressure allows to simultaneously collect all the products contained in the housing.
  • the objective of the invention is therefore to develop diffusers which make it possible to take only one or the other of the different products contained in the housing. Another objective is to allow in addition to collect all products simultaneously.
  • the endpiece comprises a cylindrical portion of circular section in which n transfer ducts are formed (thus as many transfer ducts as there are channels in the multi-channel valve), each duct being provided with means for sealingly connecting it to the outlet of the corresponding channel of the valve when it is mounted on said valve, each transfer duct opening out of the cylindrical portion of the nozzle in a different radial plane and in an angular sector different from the cylindrical part.

  • the endpiece In order to allow not only the removal of only one of the products contained in the casing, but also the simultaneous sampling of all the products, it is possible to provide the endpiece with a second set of transfer ducts comprising as many ducts. transfer that there are channels in the multi-channel valve, these transfer ducts being placed one above the other in the same axial plane, in an angular sector different from the transfer ducts of the first set, to each transfer duct the first game corresponding a transfer conduit of the second game placed in the same radial plane and communicating with it. Therefore, at each output channel of the valve there is a first transfer line and a second transfer line in the tip and an outlet line in the plug. These three ducts are in the same radial plane.
  • the seal unit can consist of as many annular seals plus one as there are channels in the multi-way valve, the annular seals being arranged one above the other and two successive annular seals being joined together. together by two straight elements so as to form a window.
  • the joint unit is constituted by a sleeve in which are made as many openings as there are channels in the multi-way valve, each opening constituting a window.

Description

L'invention concerne diffuseur pour valve multivoie à n voies munie d'un stem saillant, n étant égal ou supérieur à 2, lequel diffuseur comprenant un embout destiné à être fixé sur la partie saillante du stem. L'invention concerne notamment un diffuseur pour valve à deux voies.The invention relates to a diffuser for multi-channel valve with n lanes having a protruding stem, n being equal to or greater than 2, which diffuser comprising a nozzle intended to be fixed on the projecting part of the stem. The invention particularly relates to a diffuser for a two-way valve.

On connaît des valves multivoie notamment des documents EP 1 281 635 A1 et EP 2 024 256 A1 . Il s'agit de valves qui permettent de prélever autant de produits qu'il y a de voies sans que ces produits se croisent avant d'avoir quitté la valve. Elles sont destinées à des produits qui doivent être séparés durant le stockage et ne doivent entrer en contact qu'au moment de leur application afin d'éviter qu'ils ne réagissent ensemble prématurément.Multi-channel valves, particularly documents, are known EP 1 281 635 A1 and EP 2 024 256 A1 . These are valves that can collect as many products as there are ways without these products cross before leaving the valve. They are intended for products that must be separated during storage and must come into contact only when they are applied in order to prevent them from reacting together prematurely.

Les documents CH432404 , US3915345 et US3198394 décrivent chacun un diffuseur pour valve multivoie selon le préambule de la revendication 1.The documents CH432404 , US3915345 and US3198394 each describe a multi-channel valve diffuser according to the preamble of claim 1.

Les diffuseurs destinés à ces valves multivoies permettent d'actionner la valve. Ils sont munis de canaux de sortie qui en général ne se rencontrent pas. Cela permet donc que les produits n'entrent en contact qu'une fois qu'ils ont quitté le diffuseur. Une seule pression permet donc de prélever simultanément tous les produits contenus dans le boîtier.The diffusers intended for these multi-way valves make it possible to actuate the valve. They have exit channels that usually do not meet. This allows products to come into contact only once they have left the broadcaster. A single pressure allows to simultaneously collect all the products contained in the housing.

Cependant, il peut être utile de ne prélever que l'un des produits. Or, ces diffuseurs de l'état de la technique ne le permettent pas.However, it may be useful to only take one of the products. However, these diffusers of the state of the art do not allow it.

L'objectif de l'invention est donc de développer des diffuseurs qui permettent de ne prélever que l'un ou l'autre des différents produits contenus dans le boîtier. Un autre objectif est de permettre en plus de prélever tous les produits simultanément.The objective of the invention is therefore to develop diffusers which make it possible to take only one or the other of the different products contained in the housing. Another objective is to allow in addition to collect all products simultaneously.

Ce premier objectif est atteint du fait que l'embout comprend une partie cylindrique de section circulaire dans laquelle sont réalisés n conduits de transfert (donc autant de conduits de transfert qu'il y a de voies dans la valve multivoie), chaque conduit étant muni de moyens pour le raccorder de façon étanche à la sortie de la voie correspondante de la valve lorsqu'il est monté sur ladite valve, chaque conduit de transfert débouchant à l'extérieur de la partie cylindrique de l'embout dans un plan radial différent et dans un secteur angulaire différent de la partie cylindrique. De plus, le diffuseur est muni en outre d'un bouchon pivotant muni d'un trou borgne de forme complémentaire à la partie cylindrique de l'embout, lequel bouchon est fixé libre en rotation par des moyens appropriés sur la partie cylindrique de l'embout. Le bouchon pivotant est muni de n conduits de sortie (c'est-à-dire d'autant de conduits de sortie qu'il y a de voies dans la valve multivoie), ces conduits de sortie étant placés les uns au-dessus des autres dans un même plan axial et dans les mêmes plans radiaux que les conduits de transferts correspondants. Ainsi, à chaque voie de sortie de la valve correspond un conduit de transfert dans l'embout et un conduit de sortie dans le bouchon. Lorsque le bouchon est fixé sur l'embout, le conduit de transfert et le conduit de sortie d'une voie se trouvent dans un même plan horizontal. Ainsi, lorsque l'on fait pivoter le bouchon autour de l'embout cylindrique, on peut aligner l'un des conduits de sortie du bouchon avec le conduit de transfert correspondant de l'embout. Les autres conduits de sortie, situés au-dessus ou au-dessous du conduit de sortie aligné ne seront pas alignés avec les conduits de transfert correspondants puisque ces derniers sont tous placés dans des secteurs angulaires différents. Le conduit de transfert aligné étant relié de façon étanche à la sortie de l'une des voies de la valve multivoie, il est possible de prélever le produit correspondant du boîtier. Les autres produits ne pourront pas sortir puisque leur conduit de transfert et leur conduit de sortie ne sont pas alignés.This first objective is achieved because the endpiece comprises a cylindrical portion of circular section in which n transfer ducts are formed (thus as many transfer ducts as there are channels in the multi-channel valve), each duct being provided with means for sealingly connecting it to the outlet of the corresponding channel of the valve when it is mounted on said valve, each transfer duct opening out of the cylindrical portion of the nozzle in a different radial plane and in an angular sector different from the cylindrical part. In addition, the diffuser is further provided with a pivoting cap having a blind hole complementary to the portion cylindrical nozzle, which plug is fixed free to rotate by appropriate means on the cylindrical portion of the nozzle. The pivoting cap is provided with n outlet ducts (i.e. as many outlet ducts as there are lanes in the multi-way valve), these outlet ducts being placed one above the other. others in the same axial plane and in the same radial planes as the corresponding transfer ducts. Thus, at each outlet channel of the valve there is a transfer duct in the nozzle and an outlet duct in the plug. When the cap is fixed on the tip, the transfer duct and the outlet duct of a lane are in the same horizontal plane. Thus, when the cap is rotated around the cylindrical nozzle, one of the outlet ducts of the plug can be aligned with the corresponding transfer duct of the nozzle. The other output ducts, located above or below the aligned output duct will not be aligned with the corresponding transfer ducts since these are all placed in different angular sectors. The aligned transfer conduit being sealingly connected to the outlet of one of the channels of the multi-way valve, it is possible to take the corresponding product from the housing. The other products will not be able to leave since their transfer duct and their exit duct are not aligned.

Afin de permettre non seulement le prélèvement d'un seul des produits contenu dans le boîtier, mais également le prélèvement simultané de tous les produits, il est possible de munir l'embout d'un second jeu de conduits de transfert comprenant autant de conduits de transfert qu'il y a de voies dans la valve multivoie, ces conduits de transfert étant placés les uns au-dessus des autres dans un même plan axial, dans un secteur angulaire différent des conduits de transfert du premier jeu, à chaque conduit de transfert du premier jeu correspondant un conduit de transfert du second jeu placé dans le même plan radial et communiquant avec lui. Par conséquent, à chaque voie de sortie de la valve correspondent un premier conduit de transfert et un second conduit de transfert dans l'embout et un conduit de sortie dans le bouchon. Ces trois conduits se trouvent dans un même plan radial. Alors que les conduits de transfert du premier jeu qui permettent le prélèvement d'un seul produit sont disposés non pas les uns au-dessus des autres, mais dans des secteurs angulaires différents, ceux du deuxième jeu sont alignés verticalement comme les conduits de sortie. Ainsi, lorsque un conduit de sortie est aligné avec le conduit de transfert correspondant du second jeu de conduits de transfert, alors tous les autres conduits de transfert de ce second jeu sont alignés avec les autres conduits de sortie. L'actionnement de la valve permet de prélever tous les produits simultanément. Comme pour le premier jeu de conduits de transfert, il est préférable de prévoir des joints autour des ouvertures de sortie de chaque conduit de transfert du second jeu.In order to allow not only the removal of only one of the products contained in the casing, but also the simultaneous sampling of all the products, it is possible to provide the endpiece with a second set of transfer ducts comprising as many ducts. transfer that there are channels in the multi-channel valve, these transfer ducts being placed one above the other in the same axial plane, in an angular sector different from the transfer ducts of the first set, to each transfer duct the first game corresponding a transfer conduit of the second game placed in the same radial plane and communicating with it. Therefore, at each output channel of the valve there is a first transfer line and a second transfer line in the tip and an outlet line in the plug. These three ducts are in the same radial plane. While the transfer ducts of the first set that allow the removal of a single product are arranged not on top of each other, but in different angular sectors, those of the second set are aligned vertically as the outlet ducts. Thus, when an output duct is aligned with the corresponding transfer duct of the second set of transfer ducts, then all the other transfer ducts of this second set are aligned with the other outlet ducts. Actuation of the valve makes it possible to take all the products simultaneously. As for the first set of transfer ducts, it is preferable to provide seals around the outlet openings of each transfer duct of the second set.

Pour éviter que l'un ou l'autre produit ne pénètre dans l'interstice situé entre la face externe de la partie cylindrique de l'embout et la face interne du trou borgne du bouchon, il est préférable de prévoir des joints autour de chaque ouverture de sortie des différents conduits de transfert pour assurer l'étanchéité entre la face extérieure de la partie cylindrique de l'embout et l'intérieur du trou borgne du bouchon pivotant.To prevent one or other product from entering the gap between the outer face of the cylindrical portion of the nozzle and the inner face of the cap blind hole, it is preferable to provide seals around each outlet opening of the different transfer ducts to ensure the seal between the outer face of the cylindrical portion of the nozzle and the inside of the blind hole of the pivoting cap.

Il peut être plus simple de réunir tous les joints dans une même unité de joint présentant autant de fenêtres qu'il y a de conduits de transfert, lesdites fenêtres étant disposées de telle sorte qu'elles entourent chacune l'ouverture de sortie d'un canal de transfert. Pour cela, l'unité de joint peut être constituée d'autant de joints annulaires plus un qu'il y a de voies dans la valve multivoie, les joints annulaires étant disposés les uns au-dessus des autres et deux joints annulaires successifs étant réunis ensemble par deux éléments droits de sorte à former une fenêtre. Dans un autre mode de réalisation, l'unité de joint est constituée par une manchette dans laquelle sont réalisées autant d'ouvertures qu'il y a de voies dans la valve multivoie, chaque ouverture constituant une fenêtre.It may be simpler to join all the joints in the same joint unit having as many windows as there are transfer ducts, said windows being arranged in such a way that they each surround the outlet opening of a transfer channel. For this purpose, the seal unit can consist of as many annular seals plus one as there are channels in the multi-way valve, the annular seals being arranged one above the other and two successive annular seals being joined together. together by two straight elements so as to form a window. In another embodiment, the joint unit is constituted by a sleeve in which are made as many openings as there are channels in the multi-way valve, each opening constituting a window.

Afin de faciliter le maniement du bouchon pivotant, il est préférable de le munir d'une couronne de préhension entourant la partie centrale munie du trou borgne.In order to facilitate the handling of the pivoting cap, it is preferable to provide it with a gripping ring surrounding the central part provided with the blind hole.

Les moyens de raccord des conduits de transfert peuvent être chacun constitués par un trou aux dimensions complémentaires à celles de la sortie de la voie correspondante de la valve multivoie, de sorte à pouvoir s'emboîter de façon étanche sur ladite sortie et d'une chambre de transfert dans laquelle débouche la voie correspondante de la valve lorsque le diffuseur est en position montée sur la valve et de laquelle part le conduit de transfert correspondant du premier jeu et le cas échéant le conduit de transfert correspondant du second jeu.The connection means of the transfer ducts may each be constituted by a hole of dimensions complementary to those of the outlet of the corresponding channel of the multi-way valve, so as to be able to fit tightly on said outlet and a chamber in which the corresponding channel of the valve opens when the diffuser is in the mounted position on the valve and from which the corresponding transfer conduit of the first set and, if appropriate, the corresponding transfer conduit of the second set.

L'invention concerne également une valve multivoie munie d'un diffuseur selon l'invention et un flacon sous pression muni d'une telle valve.The invention also relates to a multi-channel valve provided with a diffuser according to the invention and a pressurized bottle provided with such a valve.

Dans un mode de réalisation privilégié de l'invention, les différentes voies de la valve multivoie ont des sorties concentriques et/ou des entrées concentriques.In a preferred embodiment of the invention, the various channels of the multi-channel valve have concentric outputs and / or concentric inputs.

Le diffuseur de l'invention est particulièrement bien adapté aux valves à deux voies. Dans ce cas, l'embout comprend une partie cylindrique de section circulaire dans laquelle sont réalisés deux conduits de transfert, chaque conduit de transfert débouchant à l'extérieur de la partie cylindrique de l'embout dans un plan radial différent et dans un même plan axial mais à 180° l'un de l'autre. De même, le bouchon pivotant est muni de deux conduits de sortie placés l'un au-dessus de l'autre dans un même plan axial et dans les mêmes plans radiaux que les conduits de transfert correspondants. L'embout de ce diffuseur à deux voies peut également comporter un second jeu de conduits de transfert comprenant deux conduits de transfert, ces conduits de transfert étant placés l'un au-dessus de l'autre dans un même plan axial, dans un plan axial perpendiculaire au plan axial contenant les conduits de transfert du premier jeu, à chaque conduit de transfert du premier jeu correspondant un conduit de transfert du second jeu placé dans le même plan radial et communiquant avec lui.The diffuser of the invention is particularly well suited to two-way valves. In this case, the endpiece comprises a cylindrical portion of circular section in which two transfer ducts are formed, each transfer duct emerging outside the cylindrical portion of the endpiece in a different radial plane and in the same plane. axial but 180 ° from each other. Similarly, the pivoting cap is provided with two outlet ducts placed one above the other in the same axial plane and in the same radial planes as the corresponding transfer ducts. The tip of this two-way diffuser may also comprise a second set of transfer ducts comprising two transfer ducts, these transfer ducts being placed one above the other in the same axial plane, in a plane axial axis perpendicular to the axial plane containing the transfer ducts of the first set, to each transfer duct of the first set corresponding a transfer duct of the second set placed in the same radial plane and communicating with it.

Il est à noter que les indications de positionnement telles que « au-dessous » ou « au-dessus », « partie inférieure » ou « partie supérieure » font référence à la position qu'aurait le diffuseur une fois monté sur un flacon sous pression placé avec la valve dirigée vers le haut, comme cela est représenté sur les figures 8, 9, et 10. Il va de soi qu'il ne s'agit pas de références spatiales absolues et que le diffuseur peut être utilisé dans toutes les positions, y compris avec la valve orientée vers le bas. Le flacon et les pièces qui le constituent, notamment le boîtier, présentent une certaine symétrie autour d'un axe fictif (A) passant par le centre du boîtier et de la valve (cf. fig. 1). On définit ainsi un premier plan longitudinal (cf. figure 3, 8a, 9a, 10a) passant par cet axe, ce plan étant vertical quand on se rapporte aux figures 8a, 9a et 10a. On définit un deuxième plan longitudinal (cf. figure 4) passant par cet axe et perpendiculaire au premier. Enfin, on définit des plans radiaux, qui sont perpendiculaires à cet axe (cf. figures 8b/c, 9b/c, 10b/c et 11 b/c). Ils sont donc horizontaux quand on se rapporte aux figures 8a, 9a et 10a. Les termes « axial » et « radial » se rapportent toujours à cet axe général.It should be noted that positioning indications such as "below" or "above", "bottom" or "top" refer to the position the diffuser would have when mounted on a pressure bottle. placed with the valve pointing upwards, as shown on the figures 8 , 9 , and 10 . It goes without saying that these are not absolute spatial references and that the diffuser can be used in all positions, including with the valve pointing downwards. The bottle and the parts that make it up, in particular the housing, have a certain symmetry around a fictitious axis (A) passing through the center of the housing and the valve (cf. Fig. 1 ). We thus define a first longitudinal plane (cf. figure 3 , 8a , 9a , 10a ) passing through this axis, this plane being vertical when referring to figures 8a , 9a and 10a . We define a second longitudinal plane (cf. figure 4 ) passing through this axis and perpendicular to the first. Finally, we define radial planes, which are perpendicular to this axis (cf. figures 8b / c, 9b / c, 10b / c and 11b / c). So they are horizontal when we talk about figures 8a , 9a and 10a . The terms "axial" and "radial" always refer to this general axis.

Le diffuseur de l'invention (1) est destiné à un flacon pressurisé muni d'une valve multivoie (8). Une valve multivoie est une valve qui comprend deux ou plusieurs voies internes qui permettent à autant de produits différents contenus dans des espaces séparés situés à l'intérieur d'un boîtier (9) d'être extraits du flacon sans entrer en contact avant la sortie de la valve. Les voies de sortie de ces valves multivoie ne doivent donc pas se rencontrer à l'intérieur de la valve. Dans l'exemple présenté ici, la valve est une valve à deux voies telle que décrite par exemple dans les demandes de brevet EP 1 281 635 A1 et EP 2 024 256 A1 .The diffuser of the invention (1) is intended for a pressurized bottle provided with a multi-channel valve (8). A multi-way valve is a valve that includes two or more internal channels that allow as many different products contained in separate spaces within a housing (9) to be removed from the bottle without coming into contact. before leaving the valve. The exit lanes of these multi-channel valves must therefore not meet inside the valve. In the example presented here, the valve is a two-way valve as described for example in patent applications. EP 1 281 635 A1 and EP 2 024 256 A1 .

Cette valve à deux voies est constituée essentiellement d'un corps de valve (81) à l'intérieur duquel sont placés de bas en haut un ressort (87), un stem (82) autour duquel sont placés un premier joint interne (85), une couronne (84), un deuxième joint interne (86) et une coupelle (83). Le corps de valve (81) est constitué essentiellement d'une paroi tubulaire traversée de part en part par un canal (811). Il est muni de deux ailettes latérales (812) symétriques qui forment deux canaux latéraux (813) ouverts vers le bas (813a) et débouchant à l'intérieur du canal (811) via des orifices de passage (814) réalisés au sommet des canaux latéraux et débouchant au niveau de la couronne (84), entre les deux joints (85, 86).This two-way valve consists essentially of a valve body (81) inside which are placed from bottom to top a spring (87), a stem (82) around which are placed a first internal seal (85) , a crown (84), a second inner seal (86) and a cup (83). The valve body (81) consists essentially of a tubular wall traversed right through by a channel (811). It is provided with two symmetrical lateral wings (812) which form two lateral channels (813) open downwards (813a) and opening inside the channel (811) via passage orifices (814) made at the top of the channels lateral and opening at the crown (84), between the two seals (85, 86).

Une première poche souple (non représentée) est fixée sur la partie inférieure du corps de valve (81), en dessous des ailettes (812). Si nécessaire, une deuxième poche peut être fixée sur le corps de valve au niveau des ailettes, la première poche étant alors contenue dans la deuxième. Le premier produit est contenu dans la première poche, le deuxième étant contenu soit dans le boîtier (9) avec le gaz propulseur, soit dans la deuxième poche, séparé du gaz propulseur. Dans ce dernier cas, il peut être prévu des orifices de passage (non représentés) dans le corps de valve, au-dessus des ailettes (812) pour laisser sortir le gaz en même temps que le deuxième produit.A first flexible pouch (not shown) is attached to the lower portion of the valve body (81), below the fins (812). If necessary, a second pocket can be attached to the valve body at the fins, the first pocket then being contained in the second. The first product is contained in the first bag, the second being contained either in the housing (9) with the propellant or in the second bag, separated from the propellant. In the latter case, passage holes (not shown) may be provided in the valve body above the fins (812) to allow gas to exit at the same time as the second product.

Le stem (82) peut se déplacer entre une position haute dans laquelle la valve est fermée (position présentée sur les figures) et une position basse dans laquelle la valve est ouverte. Ce stem (82) comporte deux canaux coaxiaux (821, 823) ouverts en haut (821 a, 823a) vers l'extérieur de la valve. Ces deux canaux ne communiquent pas. Chaque canal présente dans sa partie basse deux orifices (822, 824) mettant en contact l'intérieur du canal avec la face latérale extérieure du stem (82). Les orifices (822) du canal central (821) débouchent en dessous des orifices (824) du canal (823) annulaire. Deux joints (85, 86) sont prévus à l'intérieur du corps de valve (81). Lorsque la valve est fermée, les orifices (822) du canal central sont obstrués par le joint inférieur (85), tandis que ceux (824) du canal annulaire (823) sont obstrués par le joint supérieur (86) comme le montre la figure 4. Lorsque le stem (82) est déplacé vers le bas contre l'effet du ressort (87), les orifices (822, 824) passent en dessous de leur joint respectif et la valve est ouverte.The stem (82) can move between a high position in which the valve is closed (position shown in the figures) and a low position in which the valve is open. This stem (82) has two coaxial channels (821, 823) open at the top (821 a, 823a) towards the outside of the valve. These two channels do not communicate. Each channel has in its lower part two orifices (822, 824) bringing the interior of the channel into contact with the outer lateral face of the stem (82). The orifices (822) of the central channel (821) open below the orifices (824) of the annular channel (823). Two seals (85, 86) are provided inside the valve body (81). When the valve is closed, the orifices (822) of the central channel are obstructed by the lower seal (85), while those (824) of the annular channel (823) are obstructed by the upper seal (86) as shown in FIG. figure 4 . When the stem (82) is moved down against the effect of the spring (87), the orifices (822, 824) pass below their respective seals and the valve is opened.

Le joint inférieur (85) sert d'une part à obstruer les orifices de passage (822) du canal central (821) et d'autre part à séparer le canal (811) du corps de valve en deux espaces, le premier, en bas, destiné au passage du produit contenu dans la première poche et le deuxième, en haut, destiné au passage du produit contenu dans le boîtier ou dans la seconde poche.The lower seal (85) serves firstly to obstruct the through-holes (822) of the central channel (821) and secondly to separate the channel (811) from the valve body in two spaces, the first in bottom, for the passage of the product contained in the first pocket and the second, above, for the passage of the product contained in the housing or in the second pocket.

On remarquera que le canal central (821) du stem dépasse au-delà de l'ouverture de sortie (823a) du canal annulaire (823). De même, le canal annulaire (823) saille au-dessus de la coupelle (83).It will be appreciated that the stem central channel (821) extends beyond the outlet opening (823a) of the annular channel (823). Similarly, the annular channel (823) protrudes above the cup (83).

Ainsi réalisée, la valve à deux voies permet de prélever simultanément deux produits stockés séparément dans un boîtier sous pression lorsqu'une pression est exercée vers le bas sur le stem (82). À chaque produit correspond une voie de sortie distincte de sorte que les deux produits n'entrent en contact qu'à l'extérieur de la valve. Le premier produit contenu dans la première poche passe par le bas du canal (811) du corps de valve, pénètre dans le canal central (821) du stem via les premiers orifices (822) et sort par la première ouverture de sortie (821 a). Le second produit contenu soit dans une seconde poche entourant la première, soit dans le boîtier directement, pénètre dans les seconds canaux (813) du corps de valve, traverse les orifices (814), passe au travers des nervures de la couronne (84) et pénètre dans le canal annulaire (823) du stem via les seconds orifices (824) et sort de la valve par la seconde ouverture de sortie (823a).Thus realized, the two-way valve makes it possible to simultaneously take two products stored separately in a pressurized housing when pressure is exerted downwards on the stem (82). Each product has a separate outlet path so that the two products come into contact only on the outside of the valve. The first product contained in the first bag passes through the bottom of the channel (811) of the valve body, enters the central channel (821) of the stem via the first ports (822) and exits through the first outlet opening (821 a). ). The second product contained either in a second pocket surrounding the first, or in the housing directly, enters the second channels (813) of the valve body, passes through the orifices (814), passes through the ribs of the crown (84) and enters the annular channel (823) of the stem via the second orifices (824) and exits the valve through the second outlet opening (823a).

Pour permettre de ne prélever qu'un seul des deux produits, on a prévu le diffuseur de l'invention. Il est constitué essentiellement de deux parties : un embout (2) et un bouton pivotant (3).To allow to take only one of the two products, the diffuser of the invention was provided. It consists essentially of two parts: a tip (2) and a pivoting knob (3).

L'embout (2) est constitué d'une partie cylindrique à l'intérieur de laquelle est réalisé un trou borgne (21). Ce trou est divisé en plusieurs parties successives. Une première partie (211) est située dans le fond du trou borgne (21), c'est-à-dire en haut. Son diamètre correspond au diamètre extérieur de la paroi du stem formant le canal central (821). Une seconde partie (212) est située au niveau de l'ouverture du trou borgne, c'est-à-dire en bas. Son diamètre correspond au diamètre extérieur de la paroi formant le canal annulaire (823) du stem. Entre les deux se trouve une partie intermédiaire (213) dont le diamètre est compris entre les deux. La jonction entre la seconde partie (212) et la partie intermédiaire (213) se fait par une paroi radiale. La portion supérieure de la partie intermédiaire (213) peut être évasée (216) pour faciliter l'introduction de l'extrémité saillante du stem. Ainsi, la jonction entre la partie intermédiaire (213) et la première partie (211) est de forme tronconique. De même, il est possible d'évaser l'entrée de la seconde partie (212) en lui donnant également une forme tronconique (215).The tip (2) consists of a cylindrical portion inside which is formed a blind hole (21). This hole is divided into several successive parts. A first portion (211) is located in the bottom of the blind hole (21), that is to say at the top. Its diameter corresponds to the outside diameter of the stem wall forming the central channel (821). A second portion (212) is located at the opening of the blind hole, that is to say at the bottom. Its diameter corresponds to the outside diameter of the wall forming the annular channel (823) of the stem. Between the two is an intermediate portion (213) whose diameter is between the two. The junction between the second portion (212) and the intermediate portion (213) is via a radial wall. The upper portion of the game intermediate (213) can be flared (216) to facilitate the introduction of the projecting end of the stem. Thus, the junction between the intermediate portion (213) and the first portion (211) is of frustoconical shape. Similarly, it is possible to flare the entrance of the second portion (212) also giving it a frustoconical shape (215).

Les hauteurs des différentes parties sont choisies de telle sorte que lorsque l'on place l'embout (2) sur la partie du stem saillant au-dessus de la coupelle, l'extrémité des parois définissant les canaux (821, 823) pénètre chacune dans la partie correspondante (211, 213) du trou borgne de l'embout en formant à chaque fois une liaison étanche. L'extrémité sommitale de la paroi formant le premier canal (821) du stem et/ou l'extrémité sommitale de la paroi formant le second canal (823) du stem viennent en appui respectivement contre la paroi radiale de fond ou contre la paroi à la jonction entre la seconde partie et la partie intermédiaire.The heights of the different parts are chosen so that when the tip (2) is placed on the part of the stem projecting above the cup, the end of the walls defining the channels (821, 823) penetrates each in the corresponding part (211, 213) of the blind hole of the nozzle forming in each case a sealed connection. The top end of the wall forming the first channel (821) of the stem and / or the summit end of the wall forming the second channel (823) of the stem bear respectively against the radial bottom wall or against the wall. the junction between the second part and the intermediate part.

Une première chambre de transfert (214) cylindrique est réalisée au-dessus de la première partie (211). Son diamètre est inférieur au diamètre externe de la paroi formant le premier canal (821) du stem afin d'assurer une fonction de butée pour l'extrémité sommitale de cette paroi. Un premier conduit de transfert (22a) est réalisé radialement dans l'embout au niveau de la première chambre de transfert (214).A first cylindrical transfer chamber (214) is formed above the first portion (211). Its diameter is smaller than the outer diameter of the wall forming the first channel (821) of the stem to provide a stop function for the top end of this wall. A first transfer conduit (22a) is radially formed in the nozzle at the first transfer chamber (214).

Lorsque l'embout est monté sur une valve, une deuxième chambre de transfert (213') annulaire est formée dans l'espace défini entre la partie intermédiaire (213) et la partie de la paroi formant le premier canal (821) du stem qui saille au-dessus de la seconde ouverture (823a). Un deuxième conduit de transfert (22b) est réalisé radialement dans l'embout au niveau de la partie intermédiaire (213), et donc de la deuxième chambre de transfert (213'). Ce deuxième conduit de transfert (22b) est placé dans le même plan axial que le premier (22a), mais sur la partie opposée de la paroi cylindrique. Ainsi, les ouvertures de sortie des conduits de transfert (22a, 22b) sont situées à l'opposée l'une de l'autre. De plus, les deux conduits se trouvent dans des plans radiaux différents.When the tip is mounted on a valve, a second annular transfer chamber (213 ') is formed in the space defined between the intermediate portion (213) and the portion of the wall forming the first channel (821) of the stem. protrudes above the second opening (823a). A second transfer duct (22b) is made radially in the nozzle at the intermediate portion (213), and therefore the second transfer chamber (213 '). This second transfer duct (22b) is placed in the same axial plane as the first (22a), but on the opposite part of the cylindrical wall. Thus, the outlet openings of the transfer ducts (22a, 22b) are located opposite one another. In addition, the two ducts are in different radial planes.

Les deux conduits de transfert (22a, 22b) forment un premier jeu de conduits. Si le diffuseur doit permettre non seulement le prélèvement de l'un ou de l'autre des produits, mais également le prélèvement des deux produits simultanément, il est possible de prévoir un second jeu de conduits de transfert (23a, 23b), comme cela est montré sur la figure 11. Dans ce deuxième jeu, les deux conduits sont non seulement dans un même plan axial, perpendiculaire au plan axial du premier jeu (22a, 22b), mais leurs ouvertures de sortie sont dirigées du même côté et sont donc situées l'une au-dessus de l'autre, à 90° des ouvertures de sortie du premier jeu. Le premier conduit (23a) du second jeu est situé dans le même plan radial (à la même hauteur) que le premier conduit (22a) du premier jeu, tandis que le deuxième conduit (23b) du second jeu se trouve dans le même plan radial (à la même hauteur) que le second conduit (22b) du premier jeu. Les deux premiers conduits de transfert (22a, 23a) du premier et du deuxième jeu communiquent par la première chambre de transfert (214) de laquelle ils partent tous les deux. De même, les deux seconds conduits de transfert (22b, 23b) du premier et du deuxième jeu communiquent par la deuxième chambre de transfert (213') de laquelle ils partent tous les deux.The two transfer ducts (22a, 22b) form a first set of ducts. If the diffuser must allow not only the taking of one or the other of the products, but also the sampling of the two products simultaneously, it is possible to provide a second set of transfer conduits (23a, 23b), like this is shown on the figure 11 . In this second game, the two ducts are not only in the same axial plane, perpendicular to the axial plane of the first set (22a, 22b), but their openings output are directed on the same side and are thus located one above the other at 90 ° of the outlet openings of the first set. The first conduit (23a) of the second set is located in the same radial plane ( at the same height) as the first duct (22a) of the first set, while the second duct (23b) of the second set is in the same radial plane (at the same height) as the second duct (22b) of the first set The first two transfer ducts (22a, 23a) of the first and second sets communicate through the first transfer chamber (214) from which they both leave. Similarly, the two second transfer ducts (22b, 23b) of the first and second sets communicate by the second transfer chamber (213 ') from which they both leave.

Un épaulement (25) est prévu sur la face externe de la partie cylindrique de l'embout, en dessous du ou des deuxièmes conduits de transfert (22b, 23b). Cet épaulement sert à encliqueter le bouton pivotant (3).A shoulder (25) is provided on the outer face of the cylindrical portion of the nozzle, below the second or second transfer ducts (22b, 23b). This shoulder is used to snap the pivoting knob (3).

Afin de permettre un repérage des différents conduits de transfert (22a, 22b, 23a, 23b), il est préférable de prolonger la partie cylindrique de l'embout dans sa partie basse, c'est-à-dire au niveau de l'ouverture du trou borgne, par une paroi radiale (26) à la surface de laquelle on pourra apposer des marquages dans l'alignement des conduits. Dans l'exemple présenté, on a apposé un « A » en dessous de l'ouverture de sortie du premier conduit (22a) du premier jeu, un « B » en dessous de l'ouverture de sortie du second conduit (22b) du premier jeu, et un « OFF » à 90° de ces deux premiers marquages, face à la paroi pleine de la partie cylindrique. Si un deuxième jeu de conduits (23a, 23b) est prévu, on peut apposer par exemple un « A+B » en dessous des ouvertures de ces conduits, à l'opposée du marquage « OFF ».In order to allow identification of the different transfer ducts (22a, 22b, 23a, 23b), it is preferable to extend the cylindrical portion of the nozzle in its lower part, that is to say at the level of the opening blind hole, by a radial wall (26) on the surface of which we can affix markings in the alignment of the ducts. In the example presented, an "A" was affixed below the outlet opening of the first duct (22a) of the first set, a "B" below the outlet opening of the second duct (22b) of the first game, and a "OFF" at 90 ° of these first two markings, facing the solid wall of the cylindrical part. If a second set of ducts (23a, 23b) is provided, for example an "A + B" may be affixed below the openings of these ducts, in contrast to the "OFF" marking.

La paroi radiale (26) peut se prolonger vers le bas par une couronne axiale (27) pouvant être munie sur sa face externe de cannelures.The radial wall (26) can extend downwards by an axial ring (27) which can be provided on its outer face with flutes.

L'embout muni des deux jeux de conduits de transfert de la figure 11 est divisé, lorsqu'il est observé du dessus, en quatre secteurs angulaires de 90° chacun. Dans le premier secteur angulaire situé en bas des figures 11 b/c, la paroi de l'embout est pleine. On se trouve en face du marquage «OFF». Dans le secteur angulaire suivant (à gauche), décalé de 90° par rapport a premier, on trouve dans le plan radial supérieur le premier conduit de transfert (22a) du premier jeu et sur la paroi radiale (26) le marquage « A ». Dans le troisième secteur angulaire (en haut), situé à 180° du premier et à 90° du deuxième, on trouve les deux conduits de transfert (23a, 23b) du second jeu, placés l'un au-dessus de l'autre, mais dans deux plans radiaux différents. Sur la paroi radiale (26) on lit « A+B ». Enfin dans le quatrième cadran, on trouve le deuxième conduit de transfert (22b) du premier jeu, dans un autre plan radial que le premier et à 180° de celui-ci. Ce deuxième conduit de transfert (22b) se trouve à 90° des conduits du second jeu et à 270° de la position fermée du premier secteur angulaire.The tip provided with two sets of transfer ducts of the figure 11 is divided, when viewed from above, into four angular sectors of 90 ° each. In the first angular sector at the bottom of figures 11 b / c, the wall of the mouthpiece is full. We are in front of the "OFF" marking. In the following angular sector (on the left), shifted by 90 ° with respect to the first, the first transfer duct (22a) of the first set and the radial wall (26) contain the marking "A" in the upper radial plane. . In the third angular sector (top), located 180 ° from the first and 90 ° from the second, we find the two transfer ducts (23a, 23b) of the second set, placed one above the other, but in two different radial planes. On the radial wall (26) reads "A + B". Finally, in the fourth dial, there is the second transfer duct (22b) of the first set, in another radial plane than the first and 180 ° thereof. This second transfer duct (22b) is at 90 ° of the ducts of the second set and 270 ° of the closed position of the first angular sector.

Il va de soi qu'il n'est pas impératif que tous les secteurs angulaires soient de même taille. On comprendra que lorsqu'il y a plus de deux voies, il y aura plus de secteurs angulaires, l'important étant qu'aucun conduit de transfert du premier jeu n'ait son ouverture de sortie dans le même plan axial que l'ouverture de sortie d'un quelconque autre conduit de transfert. Au contraire, les conduits de transfert du second jeu, lorsqu'il y en a un, devront être alignés dans un même plan axial.It goes without saying that it is not imperative that all angular sectors are of the same size. It will be understood that when there are more than two channels, there will be more angular sectors, the important thing being that no transfer conduit of the first set has its exit opening in the same axial plane as the opening. output of any other transfer conduit. On the contrary, the transfer ducts of the second set, when there is one, must be aligned in the same axial plane.

Le bouton pivotant (3) comprend un trou borgne cylindrique (31) dans la paroi cylindrique duquel sont réalisés l'un au-dessus de l'autre deux conduits de sortie radiaux (32a, 32b). Une gorge (33) sert à recevoir l'épaulement (25) de l'embout (2). La position des conduits (32a, 32b) dans le trou borgne cylindrique est choisie de telle sorte que lorsque le bouchon (3) est encliqueté sur l'embout (2), le conduit de sortie supérieur (32a) du bouchon est dans le même plan radial (à la même hauteur) que le ou les premiers conduits de transfert (22a, 23a) de l'embout et le conduit de sortie inférieur (32b) est situé dans le même plan radial (à la même hauteur) que le ou les seconds conduits de transfert (22b, 23b) de l'embout.The pivoting knob (3) comprises a cylindrical blind hole (31) in the cylindrical wall of which are formed one above the other two radial outlet ducts (32a, 32b). A groove (33) serves to receive the shoulder (25) of the nozzle (2). The position of the ducts (32a, 32b) in the cylindrical blind hole is chosen such that when the plug (3) is snapped onto the nozzle (2), the upper outlet duct (32a) of the plug is in the same radial plane (at the same height) as the first transfer ducts (22a, 23a) of the nozzle and the lower outlet duct (32b) is located in the same radial plane (at the same height) as the or the second transfer ducts (22b, 23b) of the nozzle.

Pour faciliter le maniement du bouchon, le trou borgne (31) est entouré d'une couronne (34) ergonomique et une flèche (35) réalisée sur le sommet du bouton facilite le repérage de la position du bouchon.To facilitate the handling of the cap, the blind hole (31) is surrounded by an ergonomic crown (34) and an arrow (35) made on the top of the knob facilitates the identification of the position of the cap.

Afin d'assurer l'étanchéité entre l'embout (2) et le bouton pivotant (3) et d'éviter ainsi que du produit ne circule dans l'interstice compris entre ces deux pièces, on a prévu des joints autour de chaque ouverture de sortie des différents conduits de transfert (22a, 22b, 23a, 23b).In order to ensure the seal between the tip (2) and the pivoting knob (3) and to avoid that the product circulates in the gap between these two parts, there are provided joints around each opening output of the different transfer ducts (22a, 22b, 23a, 23b).

Dans l'exemple présenté ici, cette fonction est assurée par une unité de joint (4) constituée essentiellement de trois joints annulaires (41 a, 41 b, 41 c) reliés ensemble par des éléments droits (42a, 43a). Une première fenêtre (42) est formée par l'espace situé d'une part entre le joint annulaire supérieur (41 a) et le joint annulaire intermédiaire (41 b) et d'autre part entre les deux éléments droits verticaux supérieurs (42a). De même, une seconde fenêtre (43) est formée par l'espace situé d'une part entre le joint annulaire intermédiaire (41b) et le joint annulaire inférieur (41c) et d'autre part entre les deux éléments verticaux droits (43a). Les deux fenêtres sont décalées de 180° l'une par rapport à l'autre ainsi qu'en hauteur. Si l'embout comprend un deuxième jeu de conduits de transfert (23a, 23b), il faut prévoir un deuxième jeu de fenêtres placées l'une au-dessus de l'autre, décalées de 90° par rapport aux fenêtres du premier jeu (42, 43).In the example presented here, this function is provided by a joint unit (4) consisting essentially of three annular seals (41a, 41b, 41c) connected together by straight elements (42a, 43a). A first window (42) is formed by the space located on the one hand between the upper annular seal (41a) and the intermediate annular seal (41b) and secondly between the two upper vertical straight members (42a). Similarly, a second window (43) is formed by the space located on the one hand between the intermediate annular seal (41b) and the lower annular seal (41c) and on the other hand between the two upright vertical elements (43a). . The two windows are offset by 180 ° relative to each other as well as in height. If the mouthpiece comprises a second set of transfer ducts (23a, 23b), a second set of windows placed one above the other must be provided, shifted by 90 ° with respect to the windows of the first set ( 42, 43).

Cette unité de joint (4) est placée dans des gorges (24a/b) correspondantes réalisées sur la paroi externe de l'élément cylindrique de l'embout (2). Cette unité de joint est de préférence injectée sur l'embout préfabriqué. L'élastomère est injecté par une chambre d'injection (28) située sur la face sommitale de l'embout, passe par un conduit d'injection (29) débouchant dans la gorge supérieure (24a) destinée au joint annulaire supérieur (41a), se répand via les gorges verticales (24b) destinées aux éléments droits verticaux (42a, 43a) jusqu'à la gorge destinée au joint annulaire inférieur (41 c). Il se forme ainsi outre les joints annulaires (41 a, 41 b, 41 c) et les éléments verticaux (42a, 43a), une pastille (44a) dans la chambre d'injection (28) et un élément de liaison (45) dans le conduit d'injection (29).This joint unit (4) is placed in corresponding grooves (24a / b) formed on the outer wall of the cylindrical element of the nozzle (2). This seal unit is preferably injected on the prefabricated endpiece. The elastomer is injected by an injection chamber (28) located on the top face of the nozzle, passes through an injection conduit (29) opening into the upper groove (24a) for the upper annular seal (41a). spreads via the vertical grooves (24b) for vertical upright members (42a, 43a) to the groove for the lower annular seal (41c). Thus, in addition to the annular seals (41a, 41b, 41c) and the vertical elements (42a, 43a), a pellet (44a) is formed in the injection chamber (28) and a connecting element (45). in the injection conduit (29).

Dans une autre variante de réalisation non représentée, l'unité de joint est réalisée sous la forme d'un manchon cylindrique entourant la face externe de l'élément cylindrique de l'embout. Ce manchon présente un trou au niveau des ouvertures de sortie de chaque conduit de transfert du premier jeu (22a, 22b), ainsi que le cas échéant deux autres trous au niveau des ouvertures de sortie du deuxième jeu de conduits de transfert (23a, 23b).In another variant embodiment not shown, the joint unit is made in the form of a cylindrical sleeve surrounding the outer face of the cylindrical element of the tip. This sleeve has a hole at the outlet openings of each transfer duct of the first set (22a, 22b), as well as, where appropriate, two other holes at the outlet openings of the second set of transfer ducts (23a, 23b). ).

Il serait également possible de prévoir des joints distincts entourant chaque ouverture de sortie des conduits de transfert (22a, 22b, 23a, 23b).It would also be possible to provide separate seals surrounding each outlet opening of the transfer ducts (22a, 22b, 23a, 23b).

Les figures 8, 9 et 10 présentent le diffuseur de l'invention monté sur un flacon pressurisé.The figures 8 , 9 and 10 present the diffuser of the invention mounted on a pressurized bottle.

L'embout (2) est emboîté sur la partie saillante du stem (82). L'extrémité supérieure de la partie du canal central (821) saillant au-dessus du canal annulaire (823) s'emboîte de façon étanche dans la première partie (211) du trou borgne de l'embout et l'extrémité supérieure de la partie du canal annulaire (823) saillant au-dessus de la coupelle s'emboîte de façon étanche dans la seconde partie (212). Ainsi, la sortie de chaque voie de la valve à deux voies est séparée de l'autre à l'intérieur de l'embout (2). Les deux produits ne se rencontrent pas à l'intérieur de l'embout.The tip (2) is fitted on the protruding portion of the stem (82). The upper end of the central channel portion (821) projecting above the annular channel (823) sealingly engages the first portion (211) of the blind hole of the mouthpiece and the upper end of the part of the annular channel (823) protruding above the cup fits tightly in the second portion (212). Thus, the output of each channel of the two-way valve is separated from the other inside the nozzle (2). The two products do not meet inside the mouthpiece.

La première partie (211) du trou borgne et la première chambre de transfert (214) servent de moyens pour raccorder de façon étanche le premier conduit de transfert (22a) à la sortie (821a) de la première voie de la valve. De même, la deuxième partie (212) du trou borgne et la partie intermédiaire (213) formant à l'état monté la deuxième chambre de transfert (213') servent de moyens pour raccorder de façon étanche le second conduit de transfert (22b) à la sortie (823a) de la seconde voie de la valve.The first portion (211) of the blind hole and the first transfer chamber (214) serve as means for sealingly connecting the first transfer line (22a) to the outlet (821a) of the first channel of the valve. Similarly, the second portion (212) of the blind hole and the intermediate portion (213) forming the second transfer chamber (213 ') in the assembled state serve as means for sealingly connecting the second transfer conduit (22b). at the outlet (823a) of the second channel of the valve.

Le bouchon pivotant (3) est encliqueté sur l'embout (2) par pénétration de l'épaulement (25) de l'embout dans la gorge (33) du capuchon. Ce bouchon (3) peut pivoter autour de la partie cylindrique de l'embout (2). Les conduits de sortie (32a, 32b) du bouchon peuvent donc être alignés selon les besoins

  • avec le premier conduit de transfert (22a) en contact avec la voie de la valve provenant de la première poche (position « A » représentée sur la figure 9) ;
  • avec le second conduit de transfert (22b) en contact avec la voie de la valve provenant de l'intérieur du boîtier ou de la seconde poche (Position « B » représentée à la figure 10) ;
  • avec les deux conduits de transfert (23a, 23b) du second jeu de conduits s'il y en a (Position « A+B » représentée à la figure 11) ; ou
  • avec la face non percée de la paroi de l'embout (position « OFF » représentée sur la figure 8).
The pivoting cap (3) is snapped onto the tip (2) by penetration of the shoulder (25) of the tip into the groove (33) of the cap. This plug (3) can rotate around the cylindrical portion of the nozzle (2). The outlet ducts (32a, 32b) of the plug can therefore be aligned according to the needs
  • with the first transfer conduit (22a) in contact with the valve path from the first bag (position "A" shown in FIG. figure 9 );
  • with the second transfer conduit (22b) in contact with the valve path from the inside of the housing or the second pocket (Position "B" shown in FIG. figure 10 );
  • with the two transfer ducts (23a, 23b) of the second set of ducts, if any (Position "A + B" represented at figure 11 ); or
  • with the unperforated side of the end wall ("OFF" position shown on the figure 8 ).

Grâce aux joints qui entourent les sorties de chaque conduit de transfert (22a, 22b, 23a, 23b), les deux produits ne peuvent pas entrer en contact avant d'avoir quitté le capuchon pivotant.Due to the seals surrounding the outlets of each transfer conduit (22a, 22b, 23a, 23b), the two products can not come into contact before leaving the pivoting cap.

Dans la position « OFF » de la figure 8, si une pression est exercée sur le bouchon (3) et/ou sur la paroi radiale (26) de l'embout (2), le stem (82) est déplacé vers le bas, les orifices (822, 824) des canaux (821, 823) du stem sont libérés. La valve est ouverte, mais aucun des conduits de transfert (22a, 22b, 23a, 23b) n'est aligné avec l'un des conduits de sortie (32a, 32b) du bouchon. Par conséquent, aucun produit n'est expulsé du flacon.In the "OFF" position of the figure 8 if pressure is exerted on the plug (3) and / or on the radial wall (26) of the nozzle (2), the stem (82) is moved downwards, the orifices (822, 824) of the channels (821, 823) of the stem are released. The valve is open, but none of the transfer conduits (22a, 22b, 23a, 23b) are aligned with one of the outlet conduits (32a, 32b) of the plug. As a result, no product is expelled from the bottle.

Dans la position « A » représentée à la figure 9, le conduit de sortie (32a) est aligné avec le premier conduit de transfert (22a), les autres conduits (22b, 23a, 23b) étant obstrués par la paroi pleine du trou borgne (31) du bouchon. Si une pression est exercée sur le bouchon (3) ou sur la paroi radiale (26) de l'embout, le stem (82) est déplacé vers le bas, libérant les orifices (822, 824) des deux canaux (821, 823) du stem. Cependant, seul le canal central (821) se trouve en contact avec l'extérieur via le premier conduit de transfert (22a) et le premier conduit de sortie (32a). Par conséquent, seul le produit contenu dans la poche intérieure peut sortir.In position "A" represented in figure 9 , the outlet duct (32a) is aligned with the first transfer duct (22a), the other ducts (22b, 23a, 23b) being obstructed by the solid wall of the blind hole (31) of the plug. If a pressure is exerted on the plug (3) or on the radial wall (26) of the nozzle, the stem (82) is moved downwards, releasing the orifices (822, 824) of the two channels (821, 823 ) of the stem. However, only the central channel (821) is in contact with the outside via the first transfer conduit (22a) and the first output conduit (32a). Therefore, only the product contained in the inner pocket can come out.

Dans la position « B » représentée à la figure 10, le conduit de sortie (32b) est aligné avec le deuxième conduit de transfert (22b), les autres conduits (22a, 23a, 23b) étant obstrués par la paroi du trou borgne (31) du bouchon. Si une pression est exercée sur le bouchon (3) ou sur la paroi radiale (26) de l'embout, le stem est déplacé vers le bas, libérant les orifices (822, 824) des deux canaux (821, 823) du stem. Cependant, seul le canal annulaire (823) se trouve en contact avec l'extérieur via le deuxième conduit de transfert (22b) et le deuxième conduit de sortie (32b). Par conséquent, seul le produit contenu dans le boîtier ou la poche extérieure peut sortir.In position "B" represented in figure 10 , the outlet duct (32b) is aligned with the second transfer duct (22b), the other ducts (22a, 23a, 23b) being obstructed by the wall of the blind hole (31) of the plug. If pressure is exerted on the plug (3) or on the radial wall (26) of the tip, the stem is moved downwards, releasing the orifices (822, 824) of the two channels (821, 823) of the stem . However, only the annular channel (823) is in contact with the outside via the second transfer duct (22b) and the second outlet duct (32b). Therefore, only the product contained in the housing or the outer pocket can come out.

Si un deuxième jeu de conduits de transfert (23a, 23b) est prévu dans l'embout (cf. figure 11), il est alors possible de placer le bouchon dans la position « A/B » opposée à la position « OFF ». Dans ce cas, les deux conduits de sortie (32a, 32b) du bouchon sont alignés avec les deux conduits de transfert (23a, 23b) du deuxième jeu de conduits. Les conduits (22a, 22b) du premier jeu sont par contre obstrués par la paroi du trou borgne (31) du bouchon. Si une pression est exercée sur le bouchon (3) ou sur la paroi radiale (26) de l'embout, le stem est déplacé vers le bas, libérant les orifices (822, 824) des deux canaux (821, 823) du stem. Cette fois-ci, aussi bien le canal central (821) que le canal annulaire (823) du stem se trouvent en contact avec l'extérieur via les deux conduits de transfert (23a, 23b) et les deux conduits de sortie (32a, 32b). Par conséquent, les deux produits peuvent être prélevés simultanément.If a second set of transfer ducts (23a, 23b) is provided in the nozzle (cf. figure 11 ), it is then possible to place the plug in the "A / B" position opposite the "OFF" position. In this case, the two outlet ducts (32a, 32b) of the plug are aligned with the two transfer ducts (23a, 23b) of the second set of ducts. The conduits (22a, 22b) of the first set are obstructed by the wall of the blind hole (31) of the cap. If pressure is exerted on the plug (3) or on the radial wall (26) of the tip, the stem is moved downwards, releasing the orifices (822, 824) of the two channels (821, 823) of the stem . This time, both the central channel (821) and the annular channel (823) of the stem are in contact with the outside via the two transfer ducts (23a, 23b) and the two outlet ducts (32a, 32b). Therefore, both products can be sampled simultaneously.

Le principe décrit ici pour deux voies peut être généralisé à une valve ayant plus de deux voies de sortie. Les conduits de transfert du premier jeu ne seront plus disposés à 180° les uns des autres, mais seront répartis plus ou moins régulièrement selon les besoins sur toute la circonférence de l'embout. Le bouchon sera muni d'autant de conduits de sortie placés les uns au-dessus des autres qu'il y a de voies dans la valve.The principle described here for two channels can be generalized to a valve having more than two output channels. The transfer ducts of the first game will no longer be arranged 180 ° from each other, but will be distributed more or less regularly as needed over the entire circumference of the tip. The plug will be provided with as many outlet pipes placed one above the other as there are channels in the valve.

Il n'est pas nécessaire que les canaux de sortie du stem soient concentriques et ouverts vers le haut. Avec peu de modifications à la portée de l'homme du métier, il serait par exemple possible d'adapter l'embout de l'invention à une valve à deux voies à sorties parallèles telle que décrite par exemple dans le document DE 76 31 034 U1 .It is not necessary for the stem output channels to be concentric and open upward. With few modifications within the scope of the skilled person, it would for example be possible to adapt the tip of the invention to a two-way valve with parallel outputs as described for example in the document DE 76 31 034 U1 .

Grâce au diffuseur de l'invention, il est possible de ne prélever d'un récipient muni d'une valve multivoie que l'un des produits. En cas de besoin, il est cependant possible de prévoir des moyens pour prélever l'ensemble des produits simultanément, comme dans un diffuseur classique. À aucun moment, les produits n'entrent en contact les uns avec les autres avant la sortie du diffuseur. En choisissant autant de conduits de sortie (32a, 32b) qu'il y a de produits à prélever, on garantit la séparation des voies jusqu'à la sortie du diffuseur.With the diffuser of the invention, it is possible to take a container with a multi-channel valve that one of the products. If necessary, however, it is possible to provide means for taking all the products simultaneously, as in a conventional diffuser. At no time do the products come into contact with each other before the diffuser exit. By choosing as many outlet ducts (32a, 32b) as there are products to be taken, the separation of the channels is guaranteed until the exit of the diffuser.

Le diffuseur de l'invention peut être utilisé dans de nombreux domaines, notamment pour

  • des produits techniques, tels que colles, résines, lubrifiants, nettoyants, peintures, décapants, mousse polyuréthane ou autre, etc.,
  • des produits cosmétiques, tels que laits, crèmes, savons, shampoings, produits de maquillage ou de rasage, produits épilatoires, produits capillaires (colorants ou décolorants pour cheveux, produits à friser ou défriser, antipoux, ...), etc.,

  • des produits pharmaceutiques, tels que produits ophtalmologiques, sprays à usage nasal, auriculaire ou buccal, produits cicatrisants, désinfectants, produits antalgiques, anti-inflammatoires, antibiotiques, coagulants, anti-septiques, etc.,
  • des produits d'entretien tels que cires pour l'ameublement, cirages pour chaussures, produits pour laver les vitres, etc.,
  • des produits divers tels que pâtes pour empreintes (dentaires, auriculaires, ...), insecticides, désodorisants d'ambiance, etc.
The diffuser of the invention can be used in many fields, particularly for
  • technical products, such as glues, resins, lubricants, cleaners, paints, paint removers, polyurethane foam or other, etc.,
  • cosmetic products, such as milks, creams, soaps, shampoos, makeup or shaving products, depilatory products, hair products (hair dyes or bleaches, curling or straightening products, anti-lice, etc.), etc.,
  • food products such as sweet or savory sauces, spreads, cheeses, pâtés, mousses, oils, vinegars, butters, margarines, etc.,
