This selection comprises at least one feature preferably functional without structural details, or with only a part of the structural details if this part alone is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art.
    [0003] A first device embodiment according to the invention 101 of fluid distribution, and the dispensing valve 5 according to the invention which is associated with this device 101 will now be described with reference to FIGS. 1 to 2.
    [0004] The device 101 for dispensing a fluid (liquid and / or gas) comprises a reservoir 2 arranged to contain the fluid. This fluid may consist of either a liquid or a mixture of liquid and gas (for example a foam) or a gel. The fluid in the device 101 preferably comprises a liquid.
    [0005] In Figure 1, the reservoir 2 comprises a deformable reservoir, such as a flexible reservoir on which one can manually exert a pressure to expel the fluid outside the device. In general, this tank 2 could equally well be a tube or the conduit of a piston. The device 101 comprises a distribution duct 8 (made in a hard plastic part) extending longitudinally along a dispensing direction 10 and arranged to conduct the fluid in the distribution direction 10. The device 101 comprises an orifice distributor 105 connecting the reservoir 2 to the distribution duct 8.
    [0006] The device 101 comprises a dispensing valve 5 which comprises a dispensing diaphragm 9. The dispensing valve 5, in an open state, allows a passage of fluid from the interior of the tank 2 to the dispensing conduit 8 through the orifice 105, and in a closed state, does not allow a fluid passage from the inside of the tank 2 to the distribution duct 8 (by plating the distribution membrane 9 -7 against the dispensing orifice 105 so to plug the dispensing orifice). The dispensing valve 5 further comprises a connecting element 11. The dispensing membrane 9 comprises a free end 19 relative to the connecting element 11. This free end 19 is arranged to move to make the dispensing valve pass 5 between its open and closed states. The distribution membrane 9 also comprises a joining portion 20 integral with the joining element 11 and which does not move between the open and closed states of the dispensing valve 5.
    [0007] The dispensing diaphragm 9: - is, in a closed state of the dispensing valve 5, in a closed position, and is, in an open state of the dispensing valve 5, in an open position, the position opening differing from the closed position by a deflection of the free end 19 of the membrane 9 along a deflection direction 120 (perpendicular to the dispensing direction 10) while its other end 20 is held by the junction element 11.
    [0008] The device 101 comprises a return means 29 arranged to exert a force on the dispensing valve 5 (more exactly on the dispensing membrane 9), this force bringing the dispensing valve 5 from its open state to its closed state (more exactly bringing the dispensing membrane 9 from its open position to its closed position). In the case illustrated in Figure 1, the return means 29 is in contact and secured to the membrane 9. More exactly, in the case illustrated in Figure 1, the return means is part of the dispensing valve 5. According to FIG. the invention, the return means 29 comprises a pocket 106 forming a recess 107, said pocket 106 being located in the distribution duct 8, the pocket 106 being deformed by compression against a wall 109 of the distribution duct when the dispensing valve 5 is in the open state. The membrane 9 and the pocket 106 are aligned along the direction of deflection 120. The return means 29 is arranged to exert the force on the membrane 9 during a deformation of the pocket 106 by a compression of the pocket 106 along the deflection direction 120 when the dispensing valve 5 is in the open state.
    [0009] Thus, the sealing of the dispensing valve 5 is improved with respect to the state of the art. Indeed, unlike a simple tongue that would create an inhomogeneous restoring force (stronger on the side of the free end 19 than the joining portion 20), the return means 29 in the pocket 106 is, in the open state (and also preferably in the closed state) of the dispensing valve 5, resting on a wide area of a wall 109 of the distribution duct (this wide area being the contact zone between the bottom 113 and the wall 109 ), which makes it possible to exert a more homogeneous restoring force than the state of the art on the perimeter 116 of the dispensing orifice 105. Another important advantage of the pocket-shaped return means 29 is its stability in its insertion into the distribution duct 8. On the contrary, a return means according to the state of the art in the form of concave tongue may turn and become convex in the interior of the distribution duct during the inserting the dispensing valve into the dispensing duct for its assembly.
    [0010] The dispensing membrane 9 is situated between the dispensing orifice 105 and the hollow 107 of the bag 106. The bag 106 is a pouch open on one side only through an opening delimited by an outer rim 112 of the recess 107. is of smaller volume in the open state of the dispensing valve 5 than in the closed state of the dispensing valve 5. This volume is defined as being the volume of the recess 107 inside the pocket 106 until to a plane 122 in which is located the outer edge 112 of the opening. The dispensing valve 5 is held in the device by clamping between internal walls of the distribution duct 8. More exactly, the joining element 11 is clamped by internal walls of the distribution duct 8 and between internal walls of the duct. 8. Note that in the closed state (shown in Figure 1) the outer edge 112 of the hollow is pressed against a first inner wall 108 of the distribution duct. It is further noted that in the closed state (illustrated in FIG. 1), a bottom 113 of the pocket 106 (preferably located opposite the outer edge 112 of the recess with respect to a center of the recess 107 ) rests against a second inner wall 109 of the distribution duct (preferably opposite the first inner wall 108 relative to the inside of the distribution duct 8). In the open state, the outer rim 112 of the recess 107 deviates from the first inner wall 108 of the dispensing duct. The first inner wall 108 comprises the periphery 116 of the dispensing orifice so that: - in the closed state, the outer rim 112 (hatched portion in FIG. 12) of the recess 107 is in contact with the entire periphery 116 of the dispensing orifice 105 and surrounds all the periphery 116 of the dispensing orifice 105 hermetically, without allowing fluid passage between the reservoir 2 and the dispensing pipe 8, in the open state and in the closed state, the bottom 113 of the pocket 106 rests against the second inner wall 109 of the distribution duct or of an element located along the second inner wall 109, and - in the open state, the outer edge 112 of the hollow deviates from the dispensing orifice 105. When the dispensing valve 5 is in the open state, the bag 106 is deformed by compression (additional with respect to a possible compression already experienced by the bag 106 when the dispensing valve e distribution 5 is in the closed state) perpendicular distribution direction 10. In Figure 1, it is noted that the device 101 further comprises: - a main reservoir 17 of the fluid, typically inside a casing flexible plastic film, - a supply duct 6, directly connected to the reservoir 17 and arranged to conduct the fluid from the reservoir 17, - a supply valve 4, which, in an open state, allows a fluid passage of the duct supply 6 to the interior of the tank 2, and in a closed state, does not allow it. The supply valve 4 and the distribution valve 5 are connected by the connecting element 11. The two supply and distribution valves 4 and the connecting element 11 are integral and in a single piece. 12. This unique 12 piece is monoblock. The joining element 11 typically has a hardness of 70-80 Shore A. The supply valve 4 comprises a supply membrane 7. The supply membrane 7 comprises a free end 21 with respect to the connecting element 11. This free end 21 is arranged to move to pass the supply valve 4 between its open and closed states, and is located in the tank 2. The supply membrane 7 also comprises a connecting portion 22 with the This connecting part 22 is located in the supply duct 6. The device 101 also comprises an opening 125. The opening 125 is situated between the distribution and supply ducts 6.
    [0011] The opening 125 (allowing the passage of the supply membrane 7 during mounting of the valves 4 and 5 in the device 101 by insertion into the conduit 8) is blocked by the connecting element 11. When pressing on the tank 2 (more exactly, on the lid 15, typically made of a flexible plastic film) in the pressure direction 3, an overpressure is created in the tank 2, and: - the supply valve 4 (more exactly its end free 21) is pressed against the bottom wall 14 inside the tank 2 and is thus kept in its closed state, and - the dispensing valve 5 (more exactly its free end 19) deviates from a wall 108 dispensing duct 8 and is thus kept in its open state; and the fluid contained in the reservoir 2 passes through the dispensing valve 5 in the direction of pressure 3 and is expelled from the device 101 through the dispensing pipe 8 in the dispensing direction 10.
    [0012] When the pressure exerted on the reservoir 2 (more exactly, on the cover 15) in the direction of pressure 3 is released, a depression is created in the reservoir 2, and: the supply valve 4 (more exactly its free end 21) deviates from the bottom wall 14 inside the tank 2 and is thus kept in its open state, and - the dispensing valve 5 (more exactly its free end 19) is pressed against an inner wall 108 of the distribution duct 8 and is thus kept in its closed state, and the liquid contained in the supply duct 6 passes through the supply orifice 124 through the supply valve 4 parallel to the pressure direction 3 and thus refilling the reservoir 2 of liquid from the main reservoir 17 by the supply conduit 6. When no pressure is exerted on the reservoir 2 (more exactly, on the cover 15) in the direction of pressure 3, the valve of al imentation 4 and the dispensing valve 5 are both maintained in their closed state. Thus, the dispensing valve 5 is in the closed state when a pressure variation on the tank 2 is negative or zero. Note that the pocket 106 is already slightly compressed when the valve 5 is in its closed state. This ensures a good seal. By cons, to distribute fluid, the force exerted by a user on the lid 15 must be greater than the force exerted by the pocket 106 because of this slight compression.
    [0013] A second device embodiment 102 according to the invention will now be described with reference to FIGS. 3 to 5 only for its differences with respect to the first embodiment 101. In this device 102, in the open state of the dispensing valve 5, the bottom 113 of the pocket 106 deviates from the second inner wall 109 of the dispensing duct. The return means 29 comprises the pocket 106 forming the recess 107, said pocket 106 being located in the distribution duct 8, the pocket 106 being deformed by compression against a wall 108 of the dispensing duct when the dispensing valve 5 is in the open state. The second inner wall 109 comprises the periphery 116 of the dispensing orifice 105 so that: in the open state and in the closed state, the outer rim 112 of the recess 107 is in contact with the first inner wall 108 or an element (for example a stiffening element 119 forming part of the dispensing valve 5 and subsequently described) located along the first inner wall 108, - in the closed state, the bottom 113 of the pocket 106 rests against the dispensing orifice 105, and - in the open state, the bottom 113 of the pocket 106 deviates from the dispensing orifice 105. Unlike a simple tongue that would create an inhomogeneous restoring force ( greater on the side of the free end 19 than the joining portion 20), the pocket-shaped return means 29 is, in the open state (and in the closed state) of the dispensing valve 5 , resting on a wide area of a wall 108 of the distribution duct (c this wide zone being the contact zone between the edge 112 and the wall 108), which makes it possible to exert a more homogeneous restoring force all around the periphery 116 of the dispensing orifice 105.
    [0014] A third device embodiment 103 according to the invention will now be described with reference to FIGS. 6 to 9 only for its differences with respect to the second embodiment 102. In this embodiment, the dispensing valve 5 is offset from the dispensing orifice 105. The second inner wall 109 is provided with a convex boss 114 (extending longitudinally along the dispensing direction 10) and the bottom 113 of the pocket 106 is provided with a concave cavity 115 (extending longitudinally along the dispensing direction 10) of complementary shape to the convex hump 114 so that in the closed state, the concave cavity conforms to the shape of the convex hump. In the open state, the bottom 113 of the pocket 106 deviates from the second inner wall 109 of the distribution conduit, and the concave cavity 115 guides the fluid out of the device 103 centrally.
    [0015] Note that this bump 114 and this cavity 115 can be combined with any other embodiment of the invention described (in the case of the device 101, the first inner wall 108 will be provided with the convex bump 114 and the edge In the case of the device 104, the first inner wall 110 - 13 - will be provided with the convex boss 114 and the first side 117 of the loop will be provided with the concave cavity 115). Referring to Figure 9, the edge 112 is equipped with a seal in contact with the inner wall 108. The advantage of this seal is to completely close the pocket 106 hermetically, without any fluid passage or any hole between the hollow 107 and the outside of the pocket 106. This is particularly advantageous because it limits the variations in stiffness of the "spring" formed by the pocket 106 as a function of temperature. Indeed, when the temperature increases, the rigidity of a plastic or an elastomer of the pocket 106 will decrease (causing a decrease in stiffness of the "spring" formed by the pocket 106), but the air or the enclosed gas in the hollow 107 of the pocket 106 will expand and the pressure in the pocket 106 will increase (causing an increase in stiffness of the "spring" formed by the pocket 106), the two phenomena partially compensating. The pocket 106 is secured to a stiffening element 119 which is stiffer than any part of the pocket 106 and extends (preferably over the entire length (defined along the distribution direction 10) of the pocket 106 This stiffening element 119 may be combined with any other embodiment of dispensing valve 5 or device 101, 102, 103, 104 of the invention described, and allows to facilitate the insertion of the dispensing valve 5 inside the distribution duct 8 when it is mounted in a device according to the invention.
    [0016] A fourth device embodiment 104 according to the invention will now be described with reference to FIGS. 10 and 11 only for its differences with respect to the first embodiment 101. In the dispensing valve 5, the bag 106 forms in a plane (the plane of Figure 11) a closed loop within which is delimited the recess 107 so that: - in the closed state a first side 117 of the loop is pressed against a first inner wall 110 of the distribution duct, - 14 - - in the open state and in the closed state, a second side 118 of the loop (preferably located opposite the first side of the loop relative to the center of the recess 107) rests against a second inner wall 111 of the distribution duct (preferably opposed to the first inner wall relative to the inside of the distribution duct 8) or of an element (for example a rigidifying element 119 pheasant t part of the dispensing valve 5 and previously described) located along the second inner wall 111, and - in the open state, the first side 117 of the loop deviates from the first inner wall 110 of the distribution duct . The first inner wall 110 comprises the periphery 116 of the dispensing orifice 105 so that: in the closed state the first side of the loop 117 is pressed against the dispensing orifice 105 in a hermetic manner without allowing passage of fluid between the reservoir 2 and the distribution duct, - in the open state, the first side of the loop 117 deviates from the dispensing orifice 105 to allow a fluid passage between the reservoir 2 and the distribution duct .
    [0017] Note that the device 104 does not include a supply valve 4. The dispensing valve 5 may be equipped with a hole for passing a tool through the distribution duct 8 and pass this tool between the valve 5 and a wall internal of the distribution duct 8 (to push the connecting element 11) to facilitate the introduction of the valve 5 in the conduit 8. When pressing the reservoir 2 (as for a tube of toothpaste), creates an overpressure in the reservoir 2, and the dispensing valve 5 deviates from the dispensing orifice 105.
    [0018] The pocket 106 of the device 104 may be: - either open, for example in front of and behind the plane of FIG. 11 - or the pocket 106 is a fully closed pocket without any fluid passage or any hole between the recess 107 and the outside This is particularly advantageous because it limits the variations in stiffness of the "spring" formed by the pocket 106 as a function of the temperature. Indeed, when the temperature increases, the rigidity of a plastic or an elastomer of the pocket 106 will decrease (causing a decrease in stiffness of the "spring" formed by the pocket 106), but the air or the enclosed gas in the hollow 107 of the pocket 106 will expand and the pressure in the pocket 106 will increase (causing an increase in stiffness of the "spring" formed by the pocket 106), the two phenomena partially compensating. Note that, in variants, the pocket 106 of the dispensing valve 5 of each device 101, 102, 103 could be fully closed, ie without an opening delimited by the border 112. In addition, as for the third embodiment 103 , the dispensing valve 5 of the device 104 could in a variant be offset with respect to the dispensing orifice 105.
    [0019] Note that the dispensing valve 5 of the device 104 can also be adapted to be integral with a supply valve 4 as previously described with reference to the previous embodiments. In general, each dispensing valve 5 of the various device embodiments 101, 102, 103, 104 may comprise, in its recess 107, a folded blade 123 which will give an additional spring effect. This folded blade 123 is preferably metallic. This folded blade 123 is preferably bent U-shaped.
    [0020] In general, each dispensing valve 5 of the different device embodiments 101, 102, 103, 104 can be arranged in the device so as to be flush with the outlet of the distribution duct 8 towards the outside of the device according to the invention. as shown in FIGS. 6 and 11. In this way, areas comprising fluid that dries between two fluid distributions are avoided. Note that in all the figures of the previously described embodiments, directions 3 and 120 are combined. 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. In variants of each of the embodiments previously described, the membrane 9 can be reduced only in the bottom 113 or the edge 112 which can be very thin. In variants of each of the embodiments previously described, the section of the distribution duct 8 is not necessarily rectangular.
    [0021] For example, in variants of each of the embodiments previously described the feed valves 4 and distribution 5 can be spaced apart and not integral without departing from the scope of the invention. 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. The supply valve 4 can then be fixed by means of Any other means, for example clipped in addition, in variants of each of the previously described embodiments, the feed valve 4 can also be omitted.
    [0022] In addition, in variants of each of the embodiments described above, the device according to the invention may comprise several dispensing and / or supply valves (for example for dispensing several fluids). Of course, the different characteristics, shapes, variants and embodiments of the invention may be associated with each other.
