These embodiments being in no way limiting, it will be possible to consider variants of the invention comprising only a selection of characteristics described subsequently isolated from the other characteristics described (even if this selection is isolated within a sentence comprising these other characteristics), if this selection of characteristics is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art. This selection comprises at least one preferably functional feature without structural details, or with only a portion of the structural details if this portion alone is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art. . A fluid dispensing device 16 according to a preferred embodiment of the invention will now be described with reference to FIGS. 1 to 5. The fluid in the device 16 preferably comprises a liquid. This fluid may consist of either a liquid or a mixture of liquid and gas (for example a foam) or a gel. The device 16 comprises: - a reservoir 17 of this fluid, - a supply duct 6, directly connected to the reservoir 17 and arranged to conduct in a dispensing direction 10 the fluid from the reservoir 17, - a distribution duct 8 arranged to conduct the fluid in the dispensing direction 10, a deformable bag 2, - a supply valve 4, which, in an open state, allows fluid passage of the supply conduit 6 to the inside the pocket 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 inside of the bag 2 to the conduit of distribution 8, and, in a closed state, does not allow it. The deformable bag 2 is arranged to be deformed by pressing by pressing it in a direction of pressure 3. It is also arranged to open or close the supply valve 4 or distribution 5, as we press or release the pocket 2 In a closed state, the supply valve 4 prevents a passage of fluid from the supply conduit 6 to the inside of the bag 2. In a closed state, the dispensing valve 5 prevents a passage of fluid from the The pocket is delimited by a bottom wall 14 and a deformable lid 15. The dispensing valve 5 is held in the device by clamping between internal walls of the distribution duct 8.
    [0007] The supply duct 6 extends along the dispensing direction 10. The dispensing duct 8 extends along the dispensing direction 10. The supply ducts 6 and dispensing ducts 8 are in the extension l one of the other, that is to say that they extend along the same axis parallel to the dispensing direction 10. The dispensing valve 5 is not on the side of the deformable bag 2 but inside the distribution duct 8. The dispensing valve 5 is neither clipped nor welded but held by clamping between the internal walls of the distribution duct 8. The supply valve 4 and the dispensing valve 5 are connected by a connecting element 11. The two feed valves 4 and distribution 5 and the connecting element 11 are integral and in one piece 12. This single piece 12 is integral. It is made of a single material. The realization in one block of the supply valves 4 and 7 distribution 5 reduces the insertion time of these valves. There is no other clamping piece for tightening the feed valves 4 and dispensing valves 5. It should be noted that the dispensing valve 5 is completely contained in the distribution duct 8. It is noted that the joining element 11 is integrally contained in the distribution duct 8 (at the compression ready of this joining element 11). The two supply and distribution valves 4 are held in the device 16 by clamping the joining element 11 between the internal walls of the distribution duct 8. The tightening of the joining element 11 is a compression (ie a reduction of the section of the joining element 11 in a plane parallel to the view of FIG. 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 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. The supply valve 4 comprises a supply membrane 7.
    [0008] The supply membrane 7 comprises a free end 21 relative to the joining element 11. This free end 21 is arranged to move to pass the supply valve 4 between its open and closed states. The supply membrane 7 also comprises a joining portion 22 with the joining element 11. This joining portion 22 is located in the supply duct 6. The dispensing valve 5 comprises a distribution membrane 9. The membrane The free end 19 includes a free end 19 with respect to the joining element 11. This free end 19 is arranged to move to move the dispensing valve 5 between its open and closed states. The delivery membrane 9 also includes a joining portion 20 with the joining member 11. The joining portion 20, 22 of each of the supply and delivery valves 4 attached to the joining member 11, and junction element 11, are arranged on the side of the distribution ducts 8 and supply 6 and not inside the pocket 2. -8 The supply membrane 7 extends from its joining portion 22 to its free end 21. This extension is at least partly in the dispensing direction 10. The supply membrane 7 is flat. It extends from its junction portion 22 to its free end 21 at an angle 18 preferably less than 450 relative to the distribution direction 10. The supply membrane 7 extends from its joining portion 22 to its free end 21 at an angle preferably greater than 50 relative to the distribution direction 10.
    [0009] Thus, it facilitates the fact of arranging the free end of the supply membrane 7 in the pocket 2. In a preferred embodiment of the device according to the invention, the angle between the supply membrane 7 and the direction of distribution 10 is 150.
    [0010] The free end 21 of the supply membrane 7 is 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 joining element 11. The free end 21 can deform and / or move. The joining portion 22 of the supply membrane 7 is not in the pocket 2. The joining portion 22 is on the supply duct 6 side with respect to the bottom wall 14. The dispensing membrane 9 extends from its junction portion to its free end. This extension is at least partly in the distribution direction 10. The distribution membrane 9 is flat. It extends from its junction part towards its free end at an angle preferably less than 150 relative to the distribution direction 10. In a preferred embodiment of the device according to the invention illustrated in FIG. The angle between the delivery membrane 9 and the dispensing direction 10 is very slightly greater than 00 (typically between 0.10 and 10). This very small angle is not noticeable in Figure 1 but is sufficient to press the dispensing valve 5 in its closed state for a good seal. In other variants, one can have larger values of this angle (typically between 10 and 50). The free end 19 of the delivery membrane 9 is in the distribution duct 8 and not in the pocket 2. The free end 19 of the dispensing membrane 9 is the end which is not the same. side of the connecting element 11. The free end 19 of the distribution membrane 9 can be deformed and / or move. When pressing the pocket 2 (more exactly, on the lid 15) in the direction of pressure 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 exactly, against a part of the bottom wall called the feeding seat 23) and is thus kept in its closed state, and - the distribution 5 (more exactly its free end 19) deviates from a wall of the distribution duct 8 and is thus kept in its open state; and the fluid contained in the bag 2 passes through the dispensing valve 5 in the pressure direction 3 and is expelled from the device 16 via the dispensing duct 8 in the dispensing direction 10. When the pressure exerted on the pocket 2 (more exactly, on the lid 15) in the direction of pressure 3, a depression is created in the pocket 2, and: - the supply valve 4 (more precisely its free end 21) deviates from the bottom wall 14 (more exactly, of its feeding seat 23) inside the pocket 2 and is thus kept in its open state, and - the dispensing valve 5 (more exactly its free end 19) is plate against an inner wall of the distribution duct 8 (more exactly, against a part of this inner wall called dispensing seat 24) and is thus kept in its closed state, and the liquid contained in the supply duct 6 passes through the hole B through the valve supply 4 parallel to the pressure direction 3 and thus refilled the bag 2 of liquid from the tank 17 by the supply duct 6. When no pressure is exerted on the bag 2 (more exactly on the lid 15) in the direction of pressure 3, the supply valve 4 and the dispensing valve 5 are both maintained in their closed state. The device 16 also comprises a return means 29. The return means 29 is integral with the dispensing membrane 9 of the dispensing valve 5. It is supported on an inner wall of the dispensing duct 5 and is arranged to exert a force on the dispensing membrane 9. This force returns the dispensing valve 5 from its open position 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. As shown in FIG. 5, at least a portion of (preferably all) the junction portion 22 of the feed diaphragm 7 is further away from the ladle 2 (or cover 15) than the entire junction portion 20 of the the distribution membrane 9. The joining element 11 is located between the distribution valve 5 and the supply valve 4. FIG. 2 represents the cutting plane AA of FIG. 4. This cutting plane AA is perpendicular to the direction of distribution 10.
    [0011] FIG. 4 is a view of the device 16 in frontal section along the plane AA shown in FIG. 2. The internal walls of the distribution duct 8 are opposite and come closer when approaching parallel to the direction 10 (from FIG. one end of the distribution duct 8 opposite the feed duct 6) of the single piece 12. The approximation of these walls makes it possible to tighten the joining element 11 between them. The joining element 11 is held in the device 16 by clamping between internal walls of the distribution duct 8 at a step M formed by these internal walls. This step M goes up towards the pocket 2. The device 16 also comprises an opening D. The opening D is located between the distribution and feed ducts 8 and 6. The opening D (allowing the passage of the diaphragm 7 during its assembly) is plugged by the connecting element 11.
    [0012] The step M is arranged to: - compress the joining element 11 to hold the dispensing valve 5, - seal the opening D between the supply duct 6 and the distribution duct 8, so that fluid can not pass directly between the supply duct 6 and the distribution duct 8 but must pass through the pocket 2, reassemble the joining element 11 in the direction of the pocket 2. The device 16 also comprises guiding means F (comprising a plane inclined with respect to the dispensing direction 10) arranged to guide the free end 21 of the supply membrane 7 through the opening D of the distribution duct 8 into the pocket 2. Note in Figure 1 that at least a portion of (preferably all) feed seat 23 is further away from the cover 15 than is the dispensing seat 24. The device 16 also includes an output element ( optional) 13 allowing, for example, to transform a jet of fluid into a spray. The output element 13 makes it possible to reduce the circumference of the distribution duct 8. The outlet element 13 is disposed on the side of one end of the distribution duct 8 opposite the supply duct 6. It is now described with reference in Figure 6 a method of manufacturing the fluid dispenser device 16 according to the invention. The method comprises a step of inserting the dispensing valve 5 (ie preferably the single piece 12) by the distribution duct 8. The method also comprises a step of displacing this dispensing valve 5 (ie preferably single piece 12) parallel to the dispensing direction 10 in the dispensing duct 8 to position the dispensing valve 5 (ie preferably the single piece 12) to obtain the device 16 as described above with reference to the figures 1 to 5, that is to say until the connecting element 11 comes to plug the opening D and / or until the dispensing valve 5 is held in the device by clamping (of the joining element 11) between internal walls of the distribution duct 8.
    [0013] The displacement of the dispensing valve 5 (preferably the single piece 12) is effected by sliding of the dispensing valve 5 (preferably the single single piece 12) in the dispensing duct 8. The step M makes it possible to finalize the clamping of the dispensing valve 5 (more precisely of the connecting element 11) during the mounting of the device 16, so that the sliding of the dispensing valve 5 - 12 - in the distribution pipe 8 comprises, at the level of the of 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. The insertion step comprises a passage from the supply valve 4 of the distribution duct 8 to the supply duct 6 through the opening D. This insertion step comprises a guide, by the guiding means F, of the free end 21 of the supply membrane 7 through the opening D of the distribution duct 8 into the pocket 2. The output element 13 is finally inserted into the device 16, on the side of one end of the distribution duct 8 opposite the feed duct 6. Of course, the invention is not limited to the examples which have just been described and many adjustments can be made to these examples without departing from the scope of the invention. For example, the feed valves 4 and distribution 5 can be spaced apart and not integral without departing from the scope of the invention. In different variables, possibly combinable with one another: 1) the supply valve 4 can be connected to the reservoir 17 and form a single piece. 2) the dispensing valve 5 can be secured to the joining element 11 as described above, without this connecting element 11 necessarily being integral with the supply valve 4. In this case, the dispensing valve 5 is maintained in the device 16 by clamping the connecting element 11 between internal walls of the distribution duct 8. The supply valve 4 can be fixed by any other means, for example fastened by clipping in the amount by The "above" passing from the side of the bag 2, although it is true that this variant is less advantageous than that shown in Figure 1; Thus, with reference to FIG. 5, the joining element 11 can be considered in two separate elements 11a and 11b (and preferably not integral), the dispensing valve 5 being integral with the connecting element 11a, the valve supply 4 being secured to the joining element 11b (the cutting line 25 illustrates this possible separation). The dispensing valve 5 is then held in the device 16 by clamping the connecting element - 13 - 11a between internal walls of the distribution duct 8; The supply valve 4 can then preferably be held in the device 16 by clamping the connecting element 11b between internal walls of the feed duct 6; 3) the device 16 may comprise a plurality of dispensing and / or supply valves (for example for dispensing a plurality of fluids), these dispensing and supply valves preferably comprising at least one pair consisting of a dispensing valve and 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 being preferably mounted by clamping. in an outlet duct in which the distribution ducts of each of these dispensing valves open, and at least one, preferably each of these dispensing valves, is clamped in its dispensing duct on the same principle as described in FIG. reference to figures.20
