On va maintenant décrire en référence aux figures 1 à 5 un dispositif 16 de distribution de fluide selon un mode de réalisation préféré de l'invention.We will now describe with reference to Figures 1 to 5 a fluid distribution device 16 according to a preferred embodiment of the invention.

Le fluide dans le dispositif 16 comprend de préférence un liquide.The fluid in the device 16 preferably comprises a liquid.

Ce fluide peut consister soit en un liquide ou soit en un mélange de liquide et de gaz (par exemple une mousse) ou encore en un gel.This fluid can consist of either a liquid or a mixture of liquid and gas (for example a foam) or a gel.

Le dispositif 16 comprend :

  • un réservoir 17 de ce fluide,
  • un conduit d'alimentation 6, directement relié au réservoir 17 et agencé pour conduire selon une direction de distribution 10 le fluide provenant du réservoir 17,
  • un conduit de distribution 8 agencé pour conduire le fluide selon la direction de distribution 10,
  • une poche déformable 2,
  • une valve d'alimentation 4, qui, dans un état ouvert, permet un passage de fluide du conduit d'alimentation 6 vers l'intérieur de la poche 2, et, dans un état fermé, ne le permet pas, et
  • une valve de distribution 5, qui, dans un état ouvert, permet un passage de fluide de l'intérieur de la poche 2 vers le conduit de distribution 8, et, dans un état fermé, ne le permet pas.
The device 16 includes:
  • a reservoir 17 of this fluid,
  • a supply conduit 6, directly connected to the reservoir 17 and arranged to conduct the fluid coming from the reservoir 17 in a direction of distribution 10,
  • a distribution conduit 8 arranged to conduct the fluid in the direction of distribution 10,
  • a deformable pocket 2,
  • a supply valve 4, which, in an open state, allows a passage of fluid from the supply conduit 6 towards the interior of the bag 2, and, in a closed state, does not allow it, and
  • a dispensing valve 5, which, in an open state, allows a passage of fluid from the interior of the bag 2 to the dispensing conduit 8, and, in a closed state, does not allow it.

La poche déformable 2 est agencée pour être déformée par pression en appuyant dessus selon une direction de pression 3. Elle est également agencée pour ouvrir ou fermer la valve d'alimentation 4 ou de distribution 5, selon qu'on appuie ou relâche la poche 2.The deformable pocket 2 is designed to be deformed by pressure by pressing on it in a pressure direction 3. It is also arranged to open or close the supply 4 or distribution 5 valve, depending on whether the bag 2 is pressed or released.

Dans un état fermé, la valve d'alimentation 4 empêche un passage de fluide du conduit d'alimentation 6 vers l'intérieur de la poche 2.In a closed state, the supply valve 4 prevents a passage of fluid from the supply duct 6 towards the interior of the bag 2.

Dans un état fermé, la valve de distribution 5 empêche un passage de fluide de l'intérieur de la poche 2 vers le conduit de distribution 8.In a closed state, the distribution valve 5 prevents a passage of fluid from the interior of the bag 2 to the distribution duct 8.

La poche est délimitée par une paroi de fond 14 et un couvercle déformable 15.The pocket is delimited by a bottom wall 14 and a deformable cover 15.

La valve de distribution 5 est maintenue dans le dispositif par serrage entre des parois internes du conduit de distribution 8.The distribution valve 5 is held in the device by clamping between the internal walls of the distribution duct 8.

Le conduit d'alimentation 6 s'étend le long de la direction de distribution 10.The supply duct 6 extends along the distribution direction 10.

Le conduit de distribution 8 s'étend le long de la direction de distribution 10.The distribution duct 8 extends along the distribution direction 10.

Les conduits d'alimentation 6 et de distribution 8 sont dans le prolongement l'un de l'autre, c'est à dire qu'ils s'étendent le long d'un même axe parallèle à la direction de distribution 10.The supply 6 and distribution 8 conduits are in line with one another, that is to say that they extend along the same axis parallel to the distribution direction 10.

La valve de distribution 5 n'est pas du côté de la poche déformable 2 mais à l'intérieur du conduit de distribution 8. La valve de distribution 5 n'est ni clipsée ni soudée mais maintenue par serrage entre les parois internes du conduit de distribution 8.The distribution valve 5 is not on the side of the deformable pocket 2 but inside the distribution duct 8. The distribution valve 5 is neither clipped nor welded but held by clamping between the internal walls of the distribution duct distribution 8.

La valve d'alimentation 4 et la valve de distribution 5 sont reliées par un élément de jonction 11. Les deux valves d'alimentation 4 et de distribution 5 et l'élément de jonction 11 sont solidaires et en une unique pièce 12. Cette unique 12 pièce est monobloc. Elle est faite d'une seule matière. La réalisation en un seul bloc des valves d'alimentation 4 et de distribution 5 permet de réduire le temps d'insertion de ces valves. Il n'y pas d'autre pièce de serrage pour serrer les valves d'alimentation 4 et de distribution 5.The supply valve 4 and the distribution valve 5 are connected by a junction element 11. The two supply 4 and distribution 5 valves and the junction element 11 are integral and in a single piece 12. This single 12 piece is monobloc. It is made of a single material. The realization in a single block of the supply 4 and distribution 5 valves makes it possible to reduce the insertion time of these valves. There is no other clamping piece to tighten the supply 4 and distribution 5 valves.

On remarque que la valve de distribution 5 est intégralement contenue dans le conduit de distribution 8.Note that the distribution valve 5 is entirely contained in the distribution duct 8.

On remarque que l'élément de jonction 11 est intégralement contenu dans le conduit de distribution 8 (à la compression prêt de cet élément de jonction 11).It is noted that the junction element 11 is entirely contained in the distribution duct 8 (when the junction element 11 is ready for compression).

Les deux valves d'alimentation 4 et de distribution 5 sont maintenues dans le dispositif 16 par serrage de l'élément de jonction 11 entre les parois internes du conduit de distribution 8. Le serrage de l'élément de jonction 11 est une compression (i.e. une réduction de la section de l'élément de jonction 11 dans un plan parallèle à la vue de la figure 4, entre une position libre de la pièce 12 avant montage dans le dispositif 16 et sa position montée à l'intérieur du dispositif 16 comme illustré sur la figure 1) typiquement comprise entre 5% et 80%, de préférence de l'ordre de 25% +/-5%. L'élément de jonction 11 a typiquement une dureté de 70-80 Shore A.The two supply 4 and distribution 5 valves are held in the device 16 by clamping the junction element 11 between the internal walls of the distribution conduit 8. The clamping of the junction element 11 is compression (ie a reduction in the cross section of the joining element 11 in a plane parallel to the view of the figure 4 , between a free position of the part 12 before mounting in the device 16 and its position mounted inside the device 16 as illustrated in the figure 1 ) typically between 5% and 80%, preferably of the order of 25% +/- 5%. The joining element 11 typically has a hardness of 70-80 Shore A.

La valve d'alimentation 4 comprend une membrane d'alimentation 7. La membrane d'alimentation 7 comprend une extrémité libre 21 par rapport à l'élément de jonction 11. Cette extrémité libre 21 est agencée pour se déplacer pour faire passer la valve d'alimentation 4 entre ses états ouvert et fermé. La membrane d'alimentation 7 comprend aussi une partie de jonction 22 avec l'élément de jonction 11. Cette partie de jonction 22 est située dans le conduit d'alimentation 6.The supply valve 4 comprises a supply membrane 7. The supply membrane 7 comprises a free end 21 relative to the junction element 11. This free end 21 is arranged to move in order to pass the valve d 'power supply 4 between its open and closed states. The supply membrane 7 also comprises a junction part 22 with the junction element 11. This junction part 22 is located in the supply duct 6.

La valve de distribution 5 comprend une membrane de distribution 9. La membrane de distribution 9 comprend une extrémité libre 19 par rapport à l'élément de jonction 11. Cette extrémité libre 19 est agencée pour se déplacer pour faire passer la valve de distribution 5 entre ses états ouvert et fermé. La membrane de distribution 9 comprend aussi une partie de jonction 20 avec l'élément de jonction 11.The distribution valve 5 comprises a distribution membrane 9.

This free end 19 is arranged to move so as to pass the distribution valve 5 between its open and closed states. The distribution membrane 9 also includes a junction part 20 with the junction element 11.

La partie de jonction 20, 22 de chacune des valves d'alimentation 4 et de distribution 5 jointe à l'élément de jonction 11, et l'élément de jonction 11, sont disposés du côté des conduits de distribution 8 et d'alimentation 6 et non à l'intérieur de la poche 2.The junction part 20, 22 of each of the supply 4 and distribution 5 valves joined to the junction element 11, and the junction element 11, are arranged on the side of the distribution 8 and supply 6 conduits. and not inside the pocket 2.

La membrane d'alimentation 7 s'étend de sa partie de jonction 22 vers son extrémité libre 21. Cette extension est au moins en partie selon la direction de distribution 10. La membrane d'alimentation 7 est plane. Elle s'étend de sa partie de jonction 22 vers son extrémité libre 21 selon un angle 18 de préférence inférieur à 45° par rapport à la direction de distribution 10.The supply membrane 7 extends from its junction part 22 towards its free end 21. This extension is at least partly in the direction of distribution 10. The supply membrane 7 is planar. It extends from its junction part 22 towards its free end 21 at an angle 18 preferably less than 45 ° relative to the direction of distribution 10.

La membrane d'alimentation 7 s'étend de sa partie de jonction 22 vers son extrémité libre 21 selon un angle de préférence supérieur à 5° par rapport à la direction de distribution 10.The supply membrane 7 extends from its junction part 22 towards its free end 21 at an angle preferably greater than 5 ° relative to the direction of distribution 10.

Ainsi, on facilite le fait de disposer l'extrémité libre de la membrane d'alimentation 7 dans la poche 2.Thus, it facilitates the fact of having the free end of the supply membrane 7 in the pocket 2.

Dans un mode préféré de réalisation du dispositif selon l'invention, l'angle entre la membrane d'alimentation 7 et la direction de distribution 10 est de 15°.In a preferred embodiment of the device according to the invention, the angle between the supply membrane 7 and the distribution direction 10 is 15 °.

L'extrémité libre 21 de la membrane d'alimentation 7 se trouve dans la poche 2 et non dans le conduit d'alimentation 6. L'extrémité libre 21 est l'extrémité qui n'est pas du côté de l'élément de jonction 11. L'extrémité libre 21 peut se déformer et/ou se déplacer.The free end 21 of the supply membrane 7 is located in the pocket 2 and not in the supply duct 6. The free end 21 is the end which is not on the side of the junction element 11. The free end 21 can deform and / or move.

La partie de jonction 22 de la membrane d'alimentation 7 ne se trouve pas dans la poche 2. La partie de jonction 22 se trouve du côté du conduit d'alimentation 6 par rapport à la paroi de fond 14.The junction part 22 of the supply membrane 7 is not located in the pocket 2. The junction part 22 is located on the side of the supply duct 6 relative to the bottom wall 14.

La membrane de distribution 9 s'étend de sa partie de jonction vers son extrémité libre. Cette extension est au moins en partie selon la direction de distribution 10. La membrane de distribution 9 est plane. Elle s'étend de sa partie de jonction vers son extrémité libre selon un angle de préférence inférieur à 15° par rapport à la direction de distribution 10.The distribution membrane 9 extends from its junction part towards its free end. This extension is at least partly in the direction of distribution 10. The distribution membrane 9 is planar. It extends from its junction part towards its free end at an angle preferably less than 15 ° relative to the direction of distribution 10.

Dans un mode préféré de réalisation du dispositif selon l'invention illustré sur la figure 1, l'angle entre la membrane de distribution 9 et la direction de distribution 10 est très légèrement supérieur à 0° (typiquement entre 0,1° et 1°). Cet angle très faible n'est pas perceptible sur la figure 1 mais est suffisant pour plaquer la valve de distribution 5 dans son état fermé pour une bonne étanchéité. Dans d'autres variantes, on peut avoir des valeurs plus importantes de cet angle (typiquement entre 1° et 5°).In a preferred embodiment of the device according to the invention illustrated in the figure 1 , the angle between the distribution membrane 9 and the distribution direction 10 is very slightly greater than 0 ° (typically between 0.1 ° and 1 °). This very small angle is not noticeable on the figure 1 but is sufficient to press the dispensing valve 5 in its closed state for good sealing. In other variants, it is possible to have larger values of this angle (typically between 1 ° and 5 °).

L'extrémité libre 19 de la membrane de distribution 9 se trouve dans le conduit de distribution 8 et non dans la poche 2. L'extrémité libre 19 de la membrane de distribution 9 est l'extrémité qui n'est pas du côté de l'élément de jonction 11. L'extrémité libre 19 de la membrane de distribution 9 peut se déformer et/ou se déplacer.The free end 19 of the distribution membrane 9 is located in the distribution duct 8 and not in the pocket 2. The free end 19 of the distribution membrane 9 is the end which is not on the side of the junction element 11. The free end 19 of the distribution membrane 9 can deform and / or move.

Lorsque l'on appui sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3, on crée une surpression dans la poche 2, et :

  • la valve d'alimentation 4 (plus exactement son extrémité libre 21) se plaque contre la paroi de fond 14 à l'intérieur de la poche 2 (plus exactement, contre une partie de la paroi de fond appelée siège d'alimentation 23) et est donc maintenue dans son état fermé, et
  • la valve de distribution 5 (plus exactement son extrémité libre 19) s'écarte d'une paroi du conduit de distribution 8 et est donc maintenue dans son état ouvert ;
et le fluide contenu dans la poche 2 passe à travers la valve de distribution 5 selon la direction de pression 3 et est expulsé du dispositif 16 par le conduit de distribution 8 selon la direction de distribution 10.When pressing on the pocket 2 (more precisely, on the cover 15) in the pressure direction 3, an overpressure is created in the pocket 2, and:
  • the supply valve 4 (more precisely its free end 21) is pressed against the bottom wall 14 inside the pocket 2 (more precisely, against a part of the bottom wall called the supply seat 23) and is therefore kept in its closed state, and
  • the distribution valve 5 (more precisely its free end 19) moves away from a wall of the distribution duct 8 and is therefore kept in its open state;
and the fluid contained in the bag 2 passes through the distribution valve 5 in the direction of pressure 3 and is expelled from the device 16 by the distribution duct 8 in the direction of distribution 10.

Lorsque l'on relâche la pression exercée sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3, on crée une dépression dans la poche 2, et :

  • la valve d'alimentation 4 (plus exactement son extrémité libre 21) s'écarte de la paroi de fond 14 (plus exactement, de son siège d'alimentation 23) à l'intérieur de la poche 2 et est donc maintenue dans son état ouvert, et
  • la valve de distribution 5 (plus exactement son extrémité libre 19) se plaque contre une paroi interne du conduit de distribution 8 (plus exactement, contre une partie de cette paroi interne appelée siège de distribution 24) et est donc maintenue dans son état fermé,
et le liquide contenu dans le conduit d'alimentation 6 passe par le trou B à travers la valve d'alimentation 4 parallèlement à la direction de pression 3 et on re-rempli ainsi la poche 2 de liquide provenant du réservoir 17 par le conduit d'alimentation 6.When the pressure exerted on the pocket 2 (more precisely, on the cover 15) is released in the pressure direction 3, a vacuum is created in the pocket 2, and:
  • the supply valve 4 (more precisely its free end 21) moves away from the bottom wall 14 (more precisely, from its supply seat 23) inside the pocket 2 and is therefore kept in its state open, and
  • the distribution valve 5 (more precisely its free end 19) is pressed against an internal wall of the distribution duct 8 (more precisely, against a part of this internal wall called the distribution seat 24) and is therefore kept in its closed state,
and the liquid contained in the supply line 6 passes through the hole B through the supply valve 4 parallel to the pressure direction 3 and the bag 2 is thus re-filled with liquid coming from the reservoir 17 through the line d 6.

Lorsque qu'aucune pression n'est exercée sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3, la valve d'alimentation 4 et la valve de distribution 5 sont toutes deux maintenues dans leur état fermé.When no pressure is exerted on the bag 2 (more precisely, on the cover 15) in the pressure direction 3, the supply valve 4 and the distribution valve 5 are both kept in their closed state.

Le dispositif 16 comprend également un moyen de rappel 29. Le moyen de rappel 29 est solidaire de la membrane de distribution 9 de la valve de distribution 5. Il est en appui sur une paroi intérieure du conduit de distribution 5 et est agencé pour exercer une force sur la membrane de distribution 9. Cette force ramène la valve de distribution 5 de sa position ouverte à sa position fermée. Ainsi, la valve de distribution 5 est dans l'état fermé lorsqu'une variation de pression sur la poche 2 est négative ou nulle.The device 16 also includes a return means 29. The return means 29 is integral with the distribution membrane 9 of the distribution valve 5. It is supported on an inner wall of the distribution duct 5 and is arranged to exert a force on the distribution membrane 9. This force returns the distribution valve 5 from its position open to its closed position. Thus, the dispensing valve 5 is in the closed state when a pressure variation on the bag 2 is negative or zero.

Comme illustré sur la figure 5, au moins une partie de (de préférence toute la) partie de jonction 22 de la membrane d'alimentation 7 est plus éloignée de la poche 2 (ou du couvercle 15) que toute la partie de jonction 20 de la membrane de distribution 9. L'élément de jonction 11 est situé entre les valves de distribution 5 et d'alimentation 4.As illustrated in the figure 5 , at least a part of (preferably the whole) junction part 22 of the supply membrane 7 is further from the pocket 2 (or of the cover 15) than the whole junction part 20 of the distribution membrane 9. The junction element 11 is located between the distribution 5 and supply 4 valves.

La figure 2 représente le plan de coupe A-A de la figure 4. Ce plan de coupe A-A est perpendiculaire à la direction de distribution 10.The figure 2 represents the section plane AA of the figure 4 . This section plane AA is perpendicular to the direction of distribution 10.

La figure 4 est une vue du dispositif 16 en coupe frontale selon le plan A-A représenté sur la figure 2.The figure 4 is a view of the device 16 in front section along the plane AA represented on the figure 2 .

Les parois internes du conduit de distribution 8 sont opposées et se rapprochent lorsque l'on se rapproche parallèlement à la direction 10 (à partir d'une extrémité du conduit de distribution 8 à l'opposé du conduit d'alimentation 6) de l'unique pièce 12. Le rapprochement de ces parois permet de serrer l'élément de jonction 11 entre elles.The internal walls of the distribution duct 8 are opposite and approach when approached parallel to the direction 10 (from one end of the distribution duct 8 opposite the supply duct 6) of the single piece 12. The bringing together of these walls makes it possible to tighten the junction element 11 between them.

L'élément de jonction 11 est maintenu dans le dispositif 16 par serrage entre des parois internes du conduit de distribution 8 au niveau d'une marche M formée par ces parois internes. Cette marche M monte en direction de la poche 2.The junction element 11 is held in the device 16 by clamping between internal walls of the distribution duct 8 at the level of a step M formed by these internal walls. This step M rises in the direction of pocket 2.

Le dispositif 16 comprend également une ouverture D. L'ouverture D est située entre les conduits de distribution 8 et d'alimentation 6. L'ouverture D (permettant le passage de la membrane d'alimentation 7 lors de son montage) est bouchée par l'élément de jonction 11.The device 16 also includes an opening D. The opening D is located between the distribution and supply 8 conduits 6. The opening D (allowing the passage of the supply membrane 7 during its assembly) is blocked by the joining element 11.

La marche M est agencée pour :

  • comprimer l'élément de jonction 11 pour le maintien de la valve de distribution 5,
  • assurer l'étanchéité de l'ouverture D entre le conduit d'alimentation 6 et le conduit de distribution 8, de sorte que du fluide ne puisse pas passer directement entre le conduit d'alimentation 6 et le conduit de distribution 8 mais doive passer par l'intermédiaire de la poche 2,
  • remonter l'élément de jonction 11 en direction de la poche 2.
The step M is arranged for:
  • compress the junction element 11 to hold the distribution valve 5,
  • seal the opening D between the supply duct 6 and the distribution duct 8, so that fluid cannot pass directly between the supply duct 6 and the distribution duct 8 but must pass through through pocket 2,
  • reassemble the joining element 11 in the direction of the pocket 2.

Le dispositif 16 comprend aussi des moyens de guidage F (comprenant un plan incliné par rapport à la direction de distribution 10) agencés pour guider l'extrémité libre 21 de la membrane d'alimentation 7 à travers l'ouverture D du conduit de distribution 8 jusque dans la poche 2.The device 16 also includes guide means F (comprising a plane inclined relative to the direction of distribution 10) arranged to guide the free end 21 of the supply membrane 7 through the opening D of the distribution duct 8 as far as the pocket 2.

On remarque sur la figure 1 qu'au moins une partie du (de préférence tout le) siège d'alimentation 23 est plus éloigné du couvercle 15 que ne l'est le siège de distribution 24.We notice on the figure 1 that at least part of the (preferably the whole) supply seat 23 is further from the cover 15 than is the distribution seat 24.

Le dispositif 16 comprend également un élément de sortie (optionnel) 13 permettant par exemple de transformer un jet de fluide en spray. L'élément de sortie 13 permet de réduire la circonférence du conduit de distribution 8. L'élément de sortie 13 est disposé du côté d'une extrémité du conduit de distribution 8 opposée au conduit d'alimentation 6.The device 16 also includes an outlet element (optional) 13 making it possible, for example, to transform a jet of fluid into a spray. The outlet element 13 makes it possible to reduce the circumference of the distribution conduit 8. The outlet element 13 is arranged on the side of one end of the distribution conduit 8 opposite to the supply conduit 6.

Il est maintenant décrit en référence à la figure 6 un procédé de fabrication du dispositif 16 distributeur de fluide selon l'invention.It is now described with reference to the figure 6 a method of manufacturing the fluid dispenser device 16 according to the invention.

Le procédé comprend une étape d'insertion de la valve de distribution 5 (i.e. de préférence l'unique pièce 12) par le conduit de distribution 8. Le procédé comprend également une étape de déplacement de cette valve de distribution 5 (i.e. de préférence l'unique pièce 12) parallèlement à la direction de distribution 10 dans le conduit de distribution 8 jusqu'à positionner la valve de distribution 5 (i.e. de préférence l'unique pièce 12) pour obtenir le dispositif 16 tel que décrit précédemment en références aux figures 1 à 5, c'est à dire jusqu'à ce que l'élément de jonction 11 vienne boucher l'ouverture D et/ou jusqu'à ce que la valve de distribution 5 soit maintenue dans le dispositif par serrage (de l'élément de jonction 11) entre des parois internes du conduit de distribution 8.The method includes a step of inserting the dispensing valve 5 (ie preferably the single piece 12) through the dispensing conduit 8. The method also includes a step of moving this dispensing valve 5 (ie preferably the 'single piece 12) parallel to the distribution direction 10 in the distribution duct 8 until positioning the distribution valve 5 (ie preferably the single piece 12) to obtain the device 16 as described above with reference to Figures 1 to 5 , i.e. until the joining element 11 comes to block the opening D and / or until the dispensing valve 5 is held in the device by tightening (of the joining element 11) between internal walls of the distribution duct 8.

Le déplacement de la valve de distribution 5 (de préférence l'unique pièce 12) est réalisé par coulissement de la valve de distribution 5 (de préférence l'unique pièce unique 12) dans le conduit de distribution 8.The distribution valve 5 (preferably the single piece 12) is displaced by sliding the distribution valve 5 (preferably the single single piece 12) in the distribution duct 8.

La marche M permet de finaliser le serrage de la valve de distribution 5 (plus exactement de l'élément de jonction 11) lors du montage du dispositif 16, de sorte que le coulissement de la valve de distribution 5 dans le conduit de distribution 8 comprend, au niveau de la marche M, un déplacement de la valve de distribution 5 en direction de la poche 2 (i.e. vers son siège). Ceci permet d'assurer une bonne étanchéité.Step M completes the tightening of the distribution valve 5 (more precisely of the junction element 11) during assembly of the device 16, so that the sliding of the distribution valve 5 in the distribution conduit 8 comprises , at the step M, a displacement of the dispensing valve 5 in the direction of the bag 2 (ie towards its seat). This ensures a good seal.

L'étape d'insertion comprend un passage de la valve d'alimentation 4 du conduit de distribution 8 au conduit d'alimentation 6 par l'ouverture D. Cette étape d'insertion comprend un guidage, par les moyens de guidage F, de l'extrémité libre 21 de la membrane d'alimentation 7 à travers l'ouverture D du conduit de distribution 8 jusque dans la poche 2.The insertion step includes a passage from the supply valve 4 from the distribution conduit 8 to the supply conduit 6 by the opening D. This insertion step comprises guiding, by the guiding means F, of the free end 21 of the supply membrane 7 through the opening D of the distribution duct 8 as far as the pocket 2 .

L'élément de sortie 13 est finalement inséré dans le dispositif 16, du côté d'une extrémité du conduit de distribution 8 opposée au conduit d'alimentation 6.The outlet element 13 is finally inserted into the device 16, on the side of one end of the distribution duct 8 opposite the supply duct 6.

Bien sûr, l'invention n'est pas limitée aux exemples qui viennent d'être décrits et de nombreux aménagements peuvent être apportés à ces exemples sans sortir du cadre de l'invention.Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention.

Par exemple, les valves d'alimentation 4 et de distribution 5 peuvent être espacées et non solidaires sans sortir du cadre de l'invention. Dans différentes variables, éventuellement combinables entre elles :

  1. 1) la valve d'alimentation 4 peut être reliée au réservoir 17 et former une seule pièce.
  2. 2) la valve de distribution 5 peut être solidaire de l'élément de jonction 11 comme décrit précédemment, sans que cet élément de jonction 11 ne soit nécessairement solidaire de la valve d'alimentation 4. Dans ce cas, la valve de distribution 5 est maintenue dans le dispositif 16 par serrage de l'élément de jonction 11 entre des parois internes du conduit de distribution 8. La valve d'alimentation 4 peut être fixée par n'importe quel autre moyen, par exemple fixé par clipsage en la montant par « le dessus » en passant du côté de la poche 2, même s'il est vrai que cette variante est moins avantageuse de celle représentée sur la figure 1 ; Ainsi, en référence à la figure 5, on peut considérer l'élément de jonction 11 en deux éléments 11a et 11b séparés (et de préférence non solidaires), la valve de distribution 5 étant solidaire de l'élément de jonction 11a, la valve d'alimentation 4 étant solidaire de l'élément de jonction 11b (la ligne de découpe 25 illustre cette possible séparation). La valve de distribution 5 est alors maintenue dans le dispositif 16 par serrage de l'élément de jonction 11a entre des parois internes du conduit de distribution 8 ; La valve d'alimentation 4 peut de préférence être alors maintenue dans le dispositif 16 par serrage de l'élément de jonction 11b entre des parois internes du conduit de d'alimentation 6 ;
  3. 3) le dispositif 16 peut comprendre plusieurs valves de distribution et/ou d'alimentation (par exemple pour distribuer plusieurs fluides), ces valves de distribution et d'alimentation comprenant de préférence au moins une paire constituée d'une valve de distribution et d'une valve d'alimentation, les valves de chaque paire étant soit solidaires par exemple sous la forme d'une pièce unique 12 comme précédemment décrit, soit séparées comme décrit au point 2) ci-dessus ; Dans le cas de deux fluides à distribuer, le dispositif 16 peut comprendre deux valves de distribution portées par un insert supportant ces deux valves de distribution, l'ensemble formé par ces deux valves de distribution et par l'insert étant de préférence monté par serrage dans un conduit de sortie dans lequel débouchent les conduits de distribution de chacune de ces valves de distribution, et au moins une, de préférence chacune de ces valves de distribution, est maintenue par serrage dans son conduit de distribution sur le même principe que décrit en référence aux figures.
  4. 4) le couvercle 15 et la paroi 27 du réservoir 17 peuvent être réalisés en une seule pièce (une seule matière). En particulier, le corps de pompe 48 peut être inséré dans un tube à simple paroi ou à double parois, par exemple par coextrusion.
For example, the supply 4 and distribution 5 valves can be spaced and not integral without departing from the scope of the invention. In different variables, possibly combinable with each other:
  1. 1) the supply valve 4 can be connected to the reservoir 17 and form a single piece.
  2. 2) the distribution valve 5 can be integral with the junction element 11 as described above, without this junction element 11 being necessarily integral with the supply valve 4. In this case, the distribution valve 5 is held in the device 16 by tightening the junction element 11 between the internal walls of the distribution duct 8. The supply valve 4 can be fixed by any other means, for example fixed by clipping by mounting it by "The top" passing from the side of the pocket 2, even if it is true that this variant is less advantageous than that shown on the figure 1 ; So, with reference to the figure 5 , we can consider the junction element 11 in two separate elements 11a and 11b (and preferably not integral), the distribution valve 5 being integral with the junction element 11a, the supply valve 4 being integral with the junction element 11b (the cutting line 25 illustrates this possible separation). The distribution valve 5 is then held in the device 16 by clamping the junction element 11a between the internal walls of the distribution duct 8; The supply valve 4 can preferably then be held in the device 16 by clamping the junction element 11b between internal walls of the supply duct 6;
  3. 3) the device 16 may comprise several distribution and / or supply valves (for example for distributing several fluids), these distribution and supply valves preferably comprising at least one pair consisting of a distribution valve and of 'A supply valve, the valves of each pair being either integral for example in the form of a single piece 12 as previously described, or separated as described in point 2) above; In the case of two fluids to be dispensed, the device 16 may comprise two dispensing valves carried by an insert supporting these two dispensing valves, the assembly formed by these two dispensing valves and by the insert preferably being mounted by clamping in an outlet conduit into which the distribution conduits of each of these distribution valves open, and at least one, preferably each of these distribution valves, is held by clamping in its distribution conduit on the same principle as described in reference to figures.
  4. 4) the cover 15 and the wall 27 of the reservoir 17 can be made in a single piece (a single material). In particular, the pump body 48 can be inserted into a single-walled or double-walled tube, for example by coextrusion.

On va maintenant décrire, en référence aux figures 7 à 14, différentes variantes de dispositif 16 selon l'invention. Ces variantes ne seront décrites que pour leurs différences par rapport au mode de réalisation des figures 1 à 6. En particulier, les signes de références déjà introduits ne seront pas de nouveau intégralement décrits.We will now describe, with reference to figures 7 to 14 , different variants of device 16 according to the invention. These variants will only be described for their differences compared to the embodiment of the figures 1 to 6 . In particular, the reference signs already introduced will not be fully described again.

En référence aux figures 7 et 8, on remarque qu'une variante de dispositif 16 selon l'invention comprend en outre une dent ou protubérance 26 agencée pour s'enfoncer dans l'élément de jonction 11 (ou dans l'élément 11a). Ainsi, cette dent ou protubérance 26 empêche la valve de distribution 5 de glisser à l'intérieur du conduit de distribution 8.With reference to Figures 7 and 8 , it is noted that a variant of the device 16 according to the invention further comprises a tooth or protuberance 26 arranged to sink into the joining element 11 (or into the element 11a). Thus, this tooth or protuberance 26 prevents the distribution valve 5 from sliding inside the distribution duct 8.

Les forces de serrage exercées par le conduit de distribution 8 sur l'élément 11 ont une composante perpendiculaire aux parois intérieures du conduit de distribution 8 en contact de l'élément 11, la combinaison 52 de l'ensemble des composantes de ces forces de serrage étant de préférence sensiblement perpendiculaire aux parois intérieures du conduit 8 en contact de l'élément 11 (ou perpendiculaire à la direction de distribution 10) ou au moins formant un angle 53 supérieur à 45° par rapport aux parois intérieures du conduit 8 en contact de l'élément 11 (ou par rapport à la direction de distribution 10). En outre, toujours en référence aux figures 7 et 8, on remarque qu'une variante de dispositif 16 selon l'invention comprend en outre une valve de fermeture 28 située dans le conduit de distribution 8 entre la valve de distribution 5 et la sortie 30 du conduit de distribution 8 vers l'extérieur du dispositif 16. Cette valve de fermeture 28 possède :

  • un état ouvert, qui permet un passage du fluide du conduit de distribution 8 vers l'extérieur du dispositif 16, et
  • un état fermé, qui empêche un passage du fluide du conduit de distribution 8 vers l'extérieur du dispositif 16.
The clamping forces exerted by the distribution duct 8 on the element 11 have a component perpendicular to the interior walls of the distribution duct 8 in contact with the element 11, the combination 52 of all the components of these clamping forces preferably being substantially perpendicular to the interior walls of the conduit 8 in contact with the element 11 (or perpendicular to the direction of distribution 10) or at least forming an angle 53 greater than 45 ° relative to the interior walls of the conduit 8 in contact with the element 11 (or in relation to the distribution direction 10). Furthermore, always with reference to Figures 7 and 8 , it is noted that a variant of the device 16 according to the invention further comprises a closing valve 28 located in the distribution conduit 8 between the distribution valve 5 and the outlet 30 of the distribution conduit 8 to the outside of the device 16. This closing valve 28 has:
  • an open state, which allows the fluid from the distribution conduit 8 to pass outside the device 16, and
  • a closed state, which prevents a passage of the fluid from the distribution duct 8 towards the outside of the device 16.

La valve 28 est maintenue en étant elle-même compressée et déformée dans le conduit de distribution 8, dans cette variante par les parois du conduit 8 qui se rapprochent comme précédemment décrit.The valve 28 is maintained by itself being compressed and deformed in the distribution duct 8, in this variant by the walls of the duct 8 which come together as previously described.

Lorsque l'on appui sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3, on crée une surpression dans la poche 2, et la valve de fermeture 28 s'écarte de son siège 49 (qui est une paroi du conduit de distribution 8) et est donc maintenue dans son état ouvert.When pressing on the pocket 2 (more precisely, on the cover 15) in the pressure direction 3, an overpressure is created in the pocket 2, and the closing valve 28 moves away from its seat 49 (which is a wall of the distribution duct 8) and is therefore kept in its open state.

Lorsque l'on relâche la pression exercée sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3, on crée une dépression dans la poche 2, et la valve de fermeture 28 se plaque contre son siège 49 (qui est une paroi interne du conduit de distribution 8) et est donc maintenue dans son état fermé.When the pressure exerted on the pocket 2 (more precisely, on the cover 15) is released in the pressure direction 3, a vacuum is created in the pocket 2, and the closing valve 28 is pressed against its seat 49 ( which is an internal wall of the distribution duct 8) and is therefore kept in its closed state.

Ceci permet une meilleur étanchéité du dispositif 16 notamment pour éviter le séchage du fluide dans le conduit 8.This allows better sealing of the device 16, in particular to avoid drying of the fluid in the duct 8.

Le dispositif 16 comprend de préférence une dent ou protubérance 31 agencée pour s'enfoncer dans la valve 28.The device 16 preferably comprises a tooth or protuberance 31 arranged to sink into the valve 28.

Ainsi, cette dent ou protubérance 31 empêche la valve de distribution 5 de glisser à l'intérieur du conduit de distribution 8.Thus, this tooth or protuberance 31 prevents the dispensing valve 5 from sliding inside the dispensing duct 8.

La dent 31 est fabriquée en perçant un trou 39 à travers le dispositif 16 jusque dans le conduit de distribution 8. Une fois la valve 28 en place dans le conduit 8, le trou 39 est bouché par la valve 28.The tooth 31 is produced by drilling a hole 39 through the device 16 as far as the distribution conduit 8. Once the valve 28 is in place in the conduit 8, the hole 39 is blocked by the valve 28.

En référence à la figure 8, la valve de fermeture 28 et la valve de distribution 5 (avec éventuellement aussi la valve d'alimentation 4) sont de préférence solidaires en une seule pièce 32. Cette pièce 32 est de préférence réalisée en bi-injection d'une première et d'une deuxième matière. La pièce 32 comprend :

  • une partie de support, dans la première matière (rigide), comprenant de préférence :
    • ∘ une plaque 33 délimitant une paroi inférieure du conduit de distribution 8 et/ou
    • ∘ un bouchon 13 (réduction de sortie, forme « applicateur » ou moyens pour générer un spray du fluide), et
  • les valves 28, 5 (et éventuellement 4) dans la deuxième matière (plus souple que la première matière).
With reference to the figure 8 , the closing valve 28 and the dispensing valve 5 (possibly also with the supply valve 4) are preferably integral in one piece 32. This piece 32 is preferably made by bi-injection of a first and d 'a second material. Exhibit 32 includes:
  • a support part, in the first (rigid) material, preferably comprising:
    • ∘ a plate 33 delimiting a lower wall of the distribution duct 8 and / or
    • ∘ a plug 13 (output reduction, “applicator” form or means for generating a spray of the fluid), and
  • the valves 28, 5 (and possibly 4) in the second material (softer than the first material).

On remarque que la valve 28 comprend une saignée concave 54 agencée pour laisser passer le fluide lorsque la valve 28 est dans son état ouvert.Note that the valve 28 comprises a concave groove 54 arranged to let the fluid pass when the valve 28 is in its open state.

En référence aux figures 9 à 12, on remarque qu'une variante « atmosphérique » de dispositif 16 selon l'invention comprend un passage 34 (par exemple des stries) :

  • situé entre les parois intérieures du conduit de distribution 8 et l'élément 11 ou 11a (plus exactement entre la marche M et l'élément 11 ou 11a), et
  • agencé pour permettre un passage d'air du conduit de distribution 8 vers l'intérieur du réservoir 17 sans passer par la poche 2, même lorsque l'on relâche la pression exercée sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3.
With reference to Figures 9 to 12 , it is noted that an “atmospheric” variant of device 16 according to the invention comprises a passage 34 (for example streaks):
  • located between the interior walls of the distribution duct 8 and the element 11 or 11a (more precisely between the step M and the element 11 or 11a), and
  • arranged to allow air to pass from the distribution duct 8 towards the interior of the reservoir 17 without passing through the pocket 2, even when the pressure exerted on the pocket 2 (more precisely, on the cover 15) is released according to pressure direction 3.

Ainsi dans cette variante, le dispositif 16 n'est plus étanche à l'air.Thus in this variant, the device 16 is no longer airtight.

Des stries réalisées sous l'élément 11 ou 11a dans le prolongement du canal de distribution permettent avec la déformation d'une partie souple de matière de l'élément 11 ou 11a de créer des micro canaux. Ces micro canaux sont au fond des stries (creux).Streaks made under the element 11 or 11a in the extension of the distribution channel allow with the deformation of a flexible part of material of the element 11 or 11a to create micro channels. These micro channels are at the bottom of the ridges (hollow).

Les valves 4, 5 sont étanches pour empêcher des fuites du fluide 35 (qui peut consister soit en un liquide ou soit en un mélange de liquide et de gaz (par exemple une mousse) ou encore en un gel) de la poche 2 vers l'extérieur du dispositif 16.The valves 4, 5 are sealed to prevent leakage of the fluid 35 (which may consist of either a liquid or a mixture of liquid and gas (for example a foam) or a gel) from the bag 2 towards the outside of the device 16.

Par contre, la valve de distribution 5 n'est plus étanche à l'air, de sorte que :

  • lorsque l'on appui sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3, on crée une surpression dans la poche 2, de manière à expulser du fluide 35 de la poche 2 vers le conduit de distribution 8 puis vers l'extérieur du dispositif 16, mais
  • lorsque l'on relâche la pression exercée sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3 :
    • ∘ du fluide 35 est aspiré du réservoir 17 vers le conduit de d'alimentation 6 puis vers la poche 2, et
    • ∘ de l'air 36 passe de l'extérieur du dispositif 16 vers le conduit de distribution 8 et/ou vers un autre conduit dédié 37, puis vers le passage 34 puis vers un trou 38 puis vers le réservoir 17 (sans passer par la poche 2 ou par le conduit d'alimentation 6 ou par la valve d'alimentation 4),
de sorte que, dans le réservoir 17, de l'air 36 remplace du fluide 35 aspiré du réservoir 17 vers la poche 2.On the other hand, the distribution valve 5 is no longer airtight, so that:
  • when pressing on the bag 2 (more precisely, on the cover 15) in the pressure direction 3, an overpressure is created in the bag 2, so as to expel fluid 35 from the bag 2 towards the dispensing conduit 8 then towards the outside of the device 16, but
  • when the pressure exerted on the bag 2 (more precisely, on the cover 15) is released in the pressure direction 3:
    • ∘ fluid 35 is sucked from the reservoir 17 towards the supply duct 6 then towards the bag 2, and
    • ∘ air 36 passes from outside the device 16 to the distribution duct 8 and / or to another dedicated duct 37, then to the passage 34 then to a hole 38 then to the reservoir 17 (without passing through the bag 2 or via the supply duct 6 or via the supply valve 4),
so that, in the reservoir 17, air 36 replaces the fluid 35 drawn from the reservoir 17 towards the pocket 2.

Le passage 34 consiste typiquement en des stries de hauteur microscopique (typiquement entre 50 et 600 µm) formant des micro-canaux.The passage 34 typically consists of streaks of microscopic height (typically between 50 and 600 μm) forming micro-channels.

Enfin, en référence aux figures 13 et 14, on remarque qu'une variante de dispositif 16 selon l'invention peut ne pas comprendre de valve d'alimentation 4.Finally, with reference to Figures 13 and 14 , it is noted that a variant of the device 16 according to the invention may not include a supply valve 4.

Dans cette variante, le conduit d'alimentation 6, le réservoir 17 et la poche 2 sont confondus (contrairement aux variantes et modes de réalisation précédents pour lesquels ces éléments étaient clairement distincts).In this variant, the supply duct 6, the reservoir 17 and the pocket 2 are combined (unlike the previous variants and embodiments for which these elements were clearly distinct).

Lorsque l'on appui sur la poche 2 selon la direction de pression 3, on crée une surpression dans la poche 2, et la valve de distribution 5 (plus exactement son extrémité libre 19) s'écarte d'une paroi du conduit de distribution 8 et est donc maintenue dans son état ouvert ; et le fluide 35 contenu dans la poche 2 passe à travers la valve de distribution 5 selon le parcours 42 et est expulsé du dispositif 16 par le conduit de distribution 8 selon la direction de distribution 10.When the bag 2 is pressed in the direction of pressure 3, an overpressure is created in the bag 2, and the dispensing valve 5 (more precisely its free end 19) moves away from a wall of the dispensing conduit 8 and is therefore kept in its open state; and the fluid 35 contained in the bag 2 passes through the dispensing valve 5 according to the path 42 and is expelled from the device 16 by the distribution conduit 8 in the direction of distribution 10.

Lorsque l'on relâche la pression exercée sur la poche 2 (plus exactement, sur le couvercle 15) selon la direction de pression 3, on crée une dépression dans la poche 2, et la valve de distribution 5 (plus exactement son extrémité libre 19) se plaque contre une paroi interne du conduit de distribution 8 (plus exactement, contre une partie de cette paroi interne appelée siège de distribution 24) et est donc maintenue dans son état fermé sans que de l'air ne puisse rentrer de l'extérieur du dispositif 16 vers l'intérieur de la poche 2.When the pressure exerted on the bag 2 (more precisely, on the cover 15) is released in the pressure direction 3, a vacuum is created in the bag 2, and the dispensing valve 5 (more precisely its free end 19 ) is pressed against an internal wall of the distribution duct 8 (more precisely, against a part of this internal wall called distribution seat 24) and is therefore kept in its closed state without air being able to enter from the outside of the device 16 towards the inside of the pocket 2.

Le procédé de fabrication de cette variante de dispositif 16 comprend une étape d'insertion de la valve de distribution 5 par le conduit de distribution 8 et une étape de déplacement de cette valve de distribution 5 par coulissement de celle-ci dans le conduit de distribution 8 jusqu'à ce que la valve de distribution soit maintenue dans le dispositif 16 par serrage entre des parois internes du conduit de distribution 8 (c'est-à-dire par des forces de serrage exercées par le conduit de distribution 8 sur la valve 5 ou sur l'élément 11a, ces forces de serrage ayant une composante perpendiculaire aux parois intérieures du conduit de distribution 8 en contact respectivement de la valve 5 ou de l'élément 11a, la combinaison 52 de l'ensemble des composantes de ces forces de serrage étant de préférence sensiblement perpendiculaire aux parois intérieures du conduit 8 en contact respectivement de la valve 5 ou de l'élément 11a (ou perpendiculaire à la direction de distribution 10) ou au moins formant un angle 53 supérieur à 45° par rapport aux parois intérieures du conduit 8 en contact respectivement de la valve 5 ou de l'élément 11a (ou par rapport à la direction de distribution 10)).The method of manufacturing this variant of device 16 comprises a step of inserting the dispensing valve 5 through the dispensing duct 8 and a step of moving this dispensing valve 5 by sliding it in the dispensing duct 8 until the dispensing valve is held in the device 16 by clamping between internal walls of the dispensing duct 8 (i.e. by clamping forces exerted by the dispensing duct 8 on the valve 5 or on the element 11a, these clamping forces having a component perpendicular to the internal walls of the distribution duct 8 in contact respectively with the valve 5 or with the element 11a, the combination 52 of all the components of these forces preferably being substantially perpendicular to the interior walls of the duct 8 in contact respectively with the valve 5 or with the element 11a (or perpendicular to the direction of distribution 10) or at least f forming an angle 53 greater than 45 ° relative to the interior walls of the duct 8 in contact respectively with the valve 5 or with the element 11a (or with respect to the direction of distribution 10)).

Chacune des figures 13 et 14 illustre deux positions de la valve de distribution :

  • une première position 40 avant l'insertion de la valve de distribution 5 dans le conduit de distribution 8, et
  • une deuxième position 41 à la fin de l'insertion de la valve de distribution 5 dans le conduit de distribution 8.
Each of Figures 13 and 14 illustrates two positions of the distribution valve:
  • a first position 40 before the insertion of the dispensing valve 5 into the dispensing conduit 8, and
  • a second position 41 at the end of the insertion of the distribution valve 5 into the distribution duct 8.

Toutefois :

  • contrairement au cas des figures 1 à 12 pour lesquelles la valve de distribution 8 était insérée par le conduit de distribution 8 du côté de la sortie 30 faisant la jonction entre le conduit de distribution 8 et l'extérieur du dispositif 16,
  • ici, dans le cas de la variante des figures 13 et 14, la valve de distribution 8 est insérée par le conduit de distribution 8 du côté de l'entrée 43 faisant la jonction entre le conduit de distribution 8 et la poche 2.
However:
  • unlike the case of Figures 1 to 12 for which the distribution valve 8 was inserted by the distribution duct 8 on the side of the outlet 30 making the junction between the distribution duct 8 and the outside of the device 16,
  • here, in the case of the variant of Figures 13 and 14 , the distribution valve 8 is inserted through the distribution duct 8 on the side of the inlet 43 making the junction between the distribution duct 8 and the bag 2.

Cette valve 5 est solidaire de l'élément de jonction 11a qui présente une pente 50 qui augmente lorsque la valve 5 entre dans le conduit de distribution 8 par l'arrière 43. Cette pente 50 permet l'écrasement progressif de la matière de l'élément 11a pendant son introduction par coulissement le long du conduit de distribution 8. La matière ainsi comprimée permet un serrage avec le conduit de distribution 8. L'amplitude 51 de la déformation est typiquement de l'ordre de 0,1 à 0,4 mm.This valve 5 is integral with the junction element 11a which has a slope 50 which increases when the valve 5 enters the distribution duct 8 from the rear 43. This slope 50 allows the progressive crushing of the material of the element 11a during its introduction by sliding along the distribution duct 8. The material thus compressed allows tightening with the distribution duct 8. The amplitude 51 of the deformation is typically of the order of 0.1 to 0.4 mm.

On remarque que dans l'ensemble des modes de réalisation, la membrane de distribution 9 et l'élément de jonction 11 ou 11a (qui est solidaire de la membrane de distribution 9) sont situés côte à côté le long de la direction de distribution 10.Note that in all of the embodiments, the distribution membrane 9 and the junction element 11 or 11a (which is integral with the distribution membrane 9) are located side by side along the distribution direction 10 .

On remarque en outre que le siège 24 est limité à une face, de préférence plane, du conduit de distribution 8, et ne fait pas tout le tour d'une section du conduit de distribution 8 qui serait réalisée dans un plan perpendiculaire à la direction de distribution 10.It is further noted that the seat 24 is limited to one face, preferably planar, of the distribution duct 8, and does not go all the way around a section of the distribution duct 8 which would be produced in a plane perpendicular to the direction distribution 10.

Bien entendu, les différentes caractéristiques, formes, variantes et modes de réalisation de l'invention peuvent être associées les unes avec les autres.Of course, the different characteristics, forms, variants and embodiments of the invention can be associated with each other.
