These embodiments being in no way limiting, it will be possible to consider variants of the invention comprising only a selection of characteristics described or illustrated subsequently isolated from the other characteristics described or illustrated (even if this selection is isolated within a sentence including these other characteristics), if this selection of features 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 characteristic without structural details, and / 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 art. earlier.

Firstly, with reference to FIGS. 1 to 3, a first embodiment of device 101 according to the invention for dispensing a fluid will be described.

Unless otherwise stated and in a purely illustrative way: each valve of the device 101 (preferably flexible) is typically made of thermoplastic elastomer (TPE) or a thermoplastic polyurethane elastomer of 80 Shore A, all the other parts of the device 101 (typically rigid or semi-rigid) are made of polypropylene (abbreviated by PP in the following description).

The fluid comprises a liquid and / or a gas, and is preferably a liquid, a cream, a paste, a gel or a mixture thereof.

The device 101 for dispensing a fluid comprises a pocket 2 having an interior volume arranged to contain the fluid, the interior volume being delimited at least in part by a deformable wall 22.

The pocket 2 is formed by a bottom wall 21 and by the flexible deformable wall 22.

The walls 21 and 22 face each other.

The wall 22 has a concave shape oriented towards the bottom wall 21.

In the present description, any notion of displacement or mobility must be understood as a displacement or a mobility relative to the bottom wall 21.

The wall 22 forms a skirt and has an upper portion and a lower portion.

The deformable wall 22 (more precisely its lower part) is fixed or welded to the bottom wall 21.

The bottom wall 21 preferably has a planar or substantially planar shape.

The bottom wall 21 is a rigid wall, that is to say more rigid than the wall 22.

The deformable wall 22 is for example a thin wall and the bottom wall 21 is for example a wall thicker than the wall 21.

The walls 21 and 22 are for example polypropylene.

The wall 22 is preferably PP with a polymer or plastomer additive (such as for example Vistamaxx ™ 6202), in order to reduce the hardness so that the hardness of the wall 22 is less than 80 Shore D. From when excessive fineness and fragility of the wall 22 are avoided. The device 101 comprises a dispensing part 23 comprising a dispensing housing 8.

The device 101 comprises a bearing surface 25 arranged to, under the pressure and through the dispensing part 23, reduce the internal volume of the bag 2 by deforming the deformable wall 22.

The bearing surface 25 is integral with the dispensing part 23, and preferably comprises at least a part of the dispensing part 23.

The device 101 includes an output 24.

The outlet 24 opens on the outside of the device 101.

The outlet 24 is located on the distribution piece 23.

The bearing surface 25 surrounds the outlet 24.

The outlet 24 is arranged to distribute fluid in a direction substantially perpendicular to the bearing surface 25.

The outlet 24 is arranged to distribute fluid in a direction substantially parallel to an axis of elongation of the housing 8.

The device 101 comprises a dispensing orifice 108 connecting the bag 2 to the dispensing housing 8.

The device 101 comprises a dispensing valve 5 located in the dispensing housing 8, and in an open state, allows fluid passage from the inside of the bag 2 to the outlet 24 through the dispensing orifice 108. and by the dispensing housing 8, and, in a closed state, does not allow a passage of fluid from the inside of the bag 2 to the outlet 24 through the dispensing orifice 108 and the dispensing housing 8 .

The dispensing piece 23 is integral with the deformable wall 22. The dispensing piece 23 is located on an apex of the concave shape of the deformable wall 22, that is to say on the upper part of the wall 22.

The junction line between the distribution piece 23 and the deformable wall 22 is a closed curve surrounding the distribution piece 23.

At the junction between the piece 23 and the wall 22, it is noted that the wall 22 is thicker than elsewhere, especially at its periphery. In other words, the wall 22 is thicker on its upper part than on its lower part. This makes it possible to widen the deformation: a small pressure on the edge causes a greater deformation of the wall 22. The stresses are less important and this improves the service life of the device. This thicker part may carry a plurality of dispensing pieces 23 in a case with several outlets 24 (as will be seen later in the case of FIGS. 37 to 40).

The bearing surface 25 is arranged to, under the pressure, reduce the internal volume of the bag 2 by deforming (and moving) the deformable wall 22 while moving the dispensing housing 8 and the valve of distribution 5 towards the bottom wall 21. The direction of the liquid is opposite to the bearing direction on the device, and is even central.

By making the distribution piece 23 and the deformable wall 22 integral, the compactness of the device and its simplicity of use and manufacture are thus considerably improved.

The housing 8 extends along an axis that passes through the pocket 2, the deformable wall 22 and the bottom wall 21.

There is a continuity of material between the deformable wall 22 and the distribution piece 23. The wall 22 and the part 23 are grouped together in a single piece of the same material without discontinuity of material, for example in PP having a lower hardness at 80 Shore D and / or a flexural modulus less than 1000 MPa.

The bearing surface 25 is arranged to, under the effect of pressure, reduce the internal volume of the bag 2 by deforming the deformable wall 22, more exactly by crushing it in the direction of the bottom wall 21. liquid distribution direction is opposed to the bearing direction on the bearing surface 25 and the outlet is central on the deformable wall.

The distribution piece 23 is arranged to, by exerting pressure on the bearing surface 25, to move at least in a translational movement.

The deformable wall 22 has, for a maximum value of the interior volume of the pocket 2, a concave shape on the side of the interior volume of the pocket 2; for example a dome shape (substantially round or square or oval or other).

The deformable wall 22 has a shape memory. When this wall

22 does not undergo any external constraint, it resumes or remains in its shape (preferably concave) which maximizes the volume of the pocket 2.

The dispensing piece 23 is located outside the pocket 2.

The distribution piece 23 is provided with a distribution ring 28 surrounding the outlet 24.

The distribution ring 28 is screwed onto the dispensing piece 23.

The ring 28 is for example made of PP. The product exits at the level of the dispensing ring 28, the distance between the closure of the valve (more precisely the dispensing seat 105) and this dispensing ring and at a distance of less than 6 mm.

The bearing surface 25 is located partly on the distribution piece

23 (around the outlet 24) and on an outer surface of the ring 28.

This bearing surface 25, accessible from outside the device 101 by a hand of a user, has a minimum surface area of 20 mm ² .

The dispensing housing 8 comprises a small opening 224 (or a small housing 61 respectively) of the outlet housing 8 on the output side 24 which has a smaller area (or volume) than a large opening 205 (or respectively large housing 62) of the distribution housing 8 on the side of the dispensing orifice 108.

The dispensing housing may comprise two spaces (or volumes), a large housing 62 and a small housing 61 connected to the outlet 24.

The small opening 224 (or respectively small housing 61) of the distribution housing 8 on the output side 24 has an area at least twice as small as the large opening 205 of the distribution housing 8 on the side of the dispensing orifice 108 .

The passage between the large opening 205 (or respectively large housing 62) and the small opening 224 (or respectively the small housing 61) is typically by a step or filling member 29 of the housing 8. Note that this step 29 in the channel dispenser is connected to the outlet 24 and is downstream of the dispensing valve 5 (unlike the stem valve section reduction is before closing the valve).

The filling element 29 is typically the imprint of the valve 5 with a space of 0 to 0.5 mm, possibly less the cylindrical passage that connects the outlet to the housing (cylinder) output.

The filling element 29 also forms a stop 75 for the insertion of the valve 5 into the housing 8 in the direction of the outlet 24.

Such a passage makes it possible in particular to limit the dead volumes of fluid at the level of the housing and the outlet 24, and to improve the hygiene

The dispensing valve 5 comprises a portion 11 held by clamping between the inner walls of the housing 8 at the large opening 205.

Part 11 is stationary between the open and closed states of the dispensing valve.

A conduit 18 allows the passage of fluid between the portion 11 and the inner walls of the housing 8 at the large opening 205 (or respectively large housing 62).

The dispensing valve 5 comprises a movable portion 12 which, in the closed state of this dispensing valve 5, is pressed against a dispensing seat 105 so as to plug the dispensing seat 105, and in the open state of this dispensing valve 5, deviates from the dispensing seat 105 so as to open the dispensing seat 105.

The conduit 18 is provided with a stop 327 at the dispensing seat 105, this stop 327 being arranged to compress the dispensing valve, more exactly the movable portion or membrane 12 of the valve 5.

The conduit 18 runs along the housing 8 in the same direction of elongation. The conduit 18 and the housing 8 have the same direction of elongation.

The conduit 18 forms a groove dug in the dispensing part 23 from the housing 8.

This part 12 is a membrane or lamella. The dispensing valve 5 comprises a portion 12 inserted in the small opening 224 (or respectively in the small housing 61). This portion 12 is the movable membrane 12 of the valve 5. The portion 12 is located in the small housing 61 and the portion 11 is located in the large housing 62.

Part 12 is movable between the open and closed states of the dispensing valve.

The passage between the large opening 205 (or respectively large housing 62) and the small opening 224 (or respectively the small housing 61) further simplifies the mounting of the valve 5 in the housing 8, by mounting "from the rear" that is to say by pushing on the solid part 11 rather than "from the front" by pushing on the membrane or lamella 12 which is mobile and fragile.

Note further that the dispensing seat 105 is a lateral portion of the inner walls of the housing 8, that is to say that seat 105 is limited to one face, preferably flat (or curved), internal walls of the 8, and does not all around a section of the housing 8 which would be made in a plane perpendicular to the direction of elongation of the portion of the housing 8 containing the valve 5. The housing 8 has a passage groove 88 , the dispensing seat partially surrounds this groove 88, the portion 11 closes the groove 88 to form a sealed passage.

The device 101 comprises a supply duct 6 coincident (as illustrated in the figures) or connected with a reservoir 13 of fluid.

The duct 6 and / or reservoir 13 is delimited at least in part by a flexible wall 14 or a flexible bag 14, typically made of multilayer polyethylene terephthalate (PET) / aluminum / cast polypropylene (PP) film, the PET layer being towards the outside of the bag 3.

The device 101 comprises a supply orifice 124 connecting the supply duct 6 to the inside volume of the pouch 2.

The device 101 comprises a supply valve 4 which, in an open state, allows fluid passage of the supply duct 6 towards the interior of the bag 2 via the feed orifice 124, and in a closed state, does not allow a fluid passage of the conduit supply 6 to the inside of the bag 2 through the supply port 124.

The supply valve 4 is located inside the bag 2 and is arranged for:

in its closed state, press against the supply orifice 124, and

- in its open state, move away from the supply port 124.

The supply valve 4 (movable between its closed and open positions) is, in its closed state, kept pressed against a stationary part (called feeding seat, which surrounds at least partially the periphery of the supply port 124 associated) and "rigid" (ie not flexible material) of an inner wall of the bag 2. More specifically, the supply valve 4 comprises a membrane which, in the closed state of the supply valve 4, is held pressed against the feeding seat, and moves away from this feeding seat in its open state.

The feeding seat is located inside the pocket 2, on the wall 21.

At rest, that is to say without the device 101 undergoes stress or external force, the valve 5 is in its closed state.

Preferably, even if this is less essential, at rest, that is to say without the device 101 does not undergo stress or external force, the valve 4 is also in its closed state.

When the bag 2 is filled with fluid to be dispensed and the volume of the bag 2 decreases (for example due to an increase in pressure on the bearing surface 25):

- The dispensing valve 5 (more exactly the membrane 12) deviates from the dispensing seat 105 and the valve 5 is in its open state; fluid exits the outlet 24 and the bag 2 is at least partially empty

- The supply valve 4 is pressed against the supply port 124 and the valve 4 is in its closed state; fluid can not (or almost not) escape from the bag 2 to the duct 6.

When the bag 2 is filled with fluid to be dispensed and the volume of the bag 2 increases (for example by releasing a pressure on the bearing surface 25): - The dispensing valve 5 (more exactly the membrane 12) is plate on the dispensing seat 105 and the valve 5 is in its closed state; fluid can not pass from pocket 2 to outlet 24

- The supply valve 4 is "sucked" and away from the supply port 124 and the valve 4 is in its open state; fluid can pass from the duct 6 to the pocket 2 so as to refill the pocket 2.

Optionally, the outer surface of the ring 28 may carry a sponge (not shown) or a fabric or impregnating means arranged to imbibe with the fluid exiting through the outlet 24. In In this case, the outlet 24 does not open directly on the outside of the device 101 but on the sponge or fabric or impregnation means. This sponge or fabric or impregnation means hides the outlet 24. The bearing surface 25, accessible from outside the device 101 by a hand of a user, is then located at least partly on an outer surface of the sponge or fabric or impregnation means, and possibly partly on an outer surface of the ring 28. In another version, the fabric or impregnating means can be replaced or associated with a sieve to filter residues .

The inside of the duct 6 and / or reservoir 13 comprises at least one rib 15 arranged to limit a crushing of the duct 6 and / or reservoir 13 respectively and to limit an amplitude of reduction of the volume of the duct 6 and / or the tank 13, respectively.

In one embodiment of manufacturing method of the device 101, the dispensing valve 5 is mounted in the dispensing housing 8 by insertion through the dispensing orifice 108, that is to say from the inside of the pocket 22. before welding or assembling the parts 21 and 22 of the pocket 2.

A distribution channel connects the outlet 24 inside the pocket 2. This distribution channel comprises the housing 8.

A variant of the device 101 will now be described with reference to FIG. 4 only for its differences with respect to FIGS. 1 to 3. In this variant, the dispensing ring 28 is fitted or clipped onto the dispensing piece 23.

The distribution piece 23 and the movable distribution wall 83 have connection means 47,48. This connection is an interlocking, screwing or other, preferably a sealed connection.

We will now describe, with reference to Figure 5, another variant of the device 101, only for its differences from Figures 1 to 3.

In this variant, there is a continuity of material between the distribution ring 28 and the distribution piece 23. The ring 28 and the piece 23 are grouped together in a single piece of the same material without discontinuity of material, for example in PP.

We will now describe, with reference to Figure 6, another variant of the device 101, only for its differences from Figures 1 to 3.

In this variant, the device 101 comprises guiding means 26 arranged to guide a displacement of the dispensing piece 23, so as to prevent any degree of freedom in inclination of the dispensing piece 23 and to limit the movement of the piece of distribution 23 according to a single translation axis aligned in the direction of the bottom wall 21, that is to say passing through the wall 21.

The dispensing piece 23 is located inside the pocket 2.

In this variant, the device 101 does not comprise a ring 28.

The bearing surface 25 is located partly on the dispensing piece 23 (around the outlet 24) and on the outer surface (opposite inside the pocket 2) of the wall 22. The bottom wall 21 comprises a recess arranged to receive at least a portion of the distribution piece 23 after the distribution piece has moved towards the bottom wall 21.

This recess is also the guide means 26.

The bearing surface 25 does not pass through the dispensing part 23 to reduce the internal volume of the bag 2 by deforming the deformable wall 22.

A further variant of the device 101 will now be described, with reference to FIGS. 7, 8 and 9, solely for its differences with respect to the variant of FIG. 5.

In this variant of Figures 7, 8 and 9, the dispensing member 23 is arranged to, when a pressure is exerted on the bearing surface 25, move while leaving available a degree of freedom in inclination of the distribution piece 23 as illustrated in Figure 9, according to at least 2 ° inclination angle.

In this variant of Figures 7, 8 and 9, the device 101 comprises, inside the bag 2, a stop 27 arranged to limit an amplitude of displacement of the dispensing piece 23 towards the bottom wall 21.

The device 101 comprises a skirt 73 which hides the deformable wall 22 to a user looking at the device 101 from outside the device 101. A further variant of the device 101 will now be described, with reference to FIGS. its differences from the variant of Figure 5.

In this variant of FIGS. 10 and 11, the device 101 comprises guiding means 26 arranged to guide a displacement of the distribution piece 23.

The guiding means 26 are arranged to prevent any degree of freedom in inclination of the distribution piece 23 and to limit the displacement of the distribution piece 23 along a single translation axis aligned in the direction of the bottom wall 21. The guiding means 26 conceal the deformable wall 22 to a user looking at the device 101 from outside the device 101.

A second device embodiment 102 according to the invention will now be described with reference to FIGS. 12, 13 and 14 only for its differences with respect to the embodiment of FIGS. 1 to 3.

The device 102 comprises guiding means 26 arranged to guide a displacement of the distribution piece 23.

The means 26 are arranged to prevent any degree of freedom in inclination of the distribution piece 23 and to limit the displacement of the distribution piece 23 along a single translation axis aligned in the direction of the bottom wall 21.

The outlet 24 is arranged to distribute fluid in a direction substantially perpendicular to the single axis of translation of the part 23 and / or substantially parallel to the bearing surface 25. This is called lateral distribution.

The dispensing piece 23 (also called dispensing head 23) comprises:

a cap 70, and

an insert 71.

The insert 71 is inserted into the cap 70.

There is continuity of material between the deformable wall 22 and at least a part (more exactly the cap 70) of the dispensing part 23. The wall 22 and at least a part (more exactly the cap 70) of the part 23 are grouped into a single piece of the same material without discontinuity of material, for example PP.

The housing 8 is located inside the at least one portion 70 (of the distribution piece 23) having a continuity of material with the wall 22.

The valve 5 is located inside the at least one portion 70 (of the dispensing piece 23) having a continuity of material with the wall 22. The connection between the cap 70 and the insert 71 is sealed so as to have a bag 38 of air or gas sealed. This seal is obtained for example by a skirt 53 and a connection 54.

All the contact areas 53, 54 between the cap 70 and the insert 71 are sealed by clamping or ultrasonic welding.

The device 102 comprises a member 31 provided with two opposite ends, of which:

a so-called distribution end 41, and

a so-called supply end 51.

The dispensing end 41 is housed inside the dispensing part 23.

The dispensing part 23 (more exactly the insert 71) comprises a member housing 30.

The dispensing end 41 is housed inside the limb housing 30.

The dispensing end 41 is arranged to slide inside the limb housing 30

The feed end 51 carries the feed valve 4.

The limb housing 30 includes at least one lug or projection 37 arranged to lock the sliding of the limb end 41 into the limb housing 30 as long as the pressure on the bearing surface 25 is less than a minimum threshold value.

The bearing surface 25 is arranged to, under the effect of pressure, reduce the internal volume of the bag 2 by moving towards the bottom wall the dispensing piece 23 and the limb housing 30, so than :

- The dispensing end 41 slides in the limb housing 30 by sinking into the limb housing 30; considering the lug or relief 37 (which is optional) and / or the friction between the inner walls of the limb housing 30 and the end 41 and / or compression of the housing 30 (for example if the end 41 comprises a piston, the housing 30 then having in this case a spring effect to avoid the stop 32 described below), the member 31 also moves in the direction the bottom wall but with a range of motion less than the range of motion of the part 23 and the housing 30; and

- The member 31 plates the supply valve 4 in its closed position against the supply port 124, at least one time (typically the valve 4 starts to rise at the beginning of the race, then is pressed against the orifice 124 until the pressure inside the pocket 2 falls back to a certain level). This facilitates the priming of the device 102.

The dispensing end 41 is slit in its length.

The device 102 comprises a stop 32 located inside the supply duct 6.

The stop is arranged to press against the feed orifice 124 or at least be close to the feed orifice 124 in the absence of pressure on the bearing surface 23.

The feed end 51 is further provided with the stop 32.

In this embodiment the stop 32 is a plug, that is to say it is arranged to plug and close the supply port 124 when the stop 32 is pressed against the supply port 124.

At rest, that is to say without the device 102 undergoes stress or external force, the stop 32 is pressed against the supply port 124. The bearing surface 25 is arranged to, under the exerting pressure, decreasing the interior volume of the bag 2 by moving the dispensing piece 23 (and the limb housing 30, so that the dispensing end 41 slides in the limb housing by sinking into the member housing) so that the member 31 moves its stop 32 away from the feed port 124.

In this embodiment, the housing 8 has a letter shape T. The dispensing valve 5 is in the top bar of T. The dispensing valve 5 is in the cap 70.

The seat 105 is in the cap 70.

The portion 11 of the valve 5 is clamped between inner walls of the housing 8 (inside the cap 70).

To limit the dead volume of the housing 8, the dispensing head 23 comprises a zone 38 (or volume) "prohibited" in which the fluid to be dispensed can not penetrate. This also makes it easier to initiate the device 102.

This zone 38 is for example an air cavity or a zone filled with material, for example PP.

Thus, the housing 30 is surrounded, in a 360 ° circumference around the housing 30, in majority (more than 180 °, preferably more than 270 °) by the zone 38 and in addition at least by a portion 56 (the lower bar T) housing 8. This channel 56 is also in the cap 70, but could alternatively be in the insert 71.

The reservoir 13 is not formed by a flexible bag but not rigid walls made of PP.

The reservoir 13 is formed:

by a peripheral space 131 (typically in the form of a hollow cylinder formed by two concentric cylinders) in which a piston 132 (typically annular) moves or slides as a function of the volume of fluid to be dispensed remaining in the reservoir 13, and

by a central space 133 surrounded by the peripheral space 131 and communicating with this peripheral space 131.

The orifice 124 opens into the central space 133.

There is an opening between the spaces 131 and 133 so that the fluid can pass between these two spaces 131 and 133. This opening is located at the top of the spaces 131 and 133, that is to say above a stop for the piston 132, that is to say that this opening is arranged to allow a passage of fluid between the spaces 131 and 133 regardless of the position of the piston 32.

The device 102 comprises a recharging connector 35 arranged to allow fluid to be recharged inside the device 102 (more exactly inside the conduit 6 and / or reservoir 13) without this fluid passing through the bag 2 or the dispensing valve 5 or the supply valve 4.

The connector 35 comprises a refill valve 39 which:

- at rest is closed, and

- Is arranged to open when the means 35 are connected to a source of fluid to be dispensed.

The valve 39 opens into the central space 133. The wall 22 has a wavy shape. This makes it easier to deform and / or to have a spring effect.

In one embodiment of manufacturing method of the device 102, the dispensing valve 5 is mounted in the dispensing housing 8 by insertion through the outlet 24.

This makes it possible to have a monoblock distribution head 23 with a lateral distribution.

It is noted that the piston 132 slides inside the device 102 without the outside of the device 102 is deformed.

A variant of the second device embodiment 102 according to the invention will now be described with reference to FIGS. 15, 16 and 17 only for its differences with respect to FIGS. 12 to 14.

In this variant, the stop 32 is provided with a through hole 33.

The supply duct 6 is provided with a through hole 34.

The stop 32 is arranged to block any flow of fluid through the supply orifice 124 as the through hole 33 of the stop 32 does not face the through hole 34 of the supply duct 6.

The through hole 33 of the abutment 32 does not face the through hole 34 of the supply duct 6 in the absence of pressure on the bearing surface 25.

The housing 30 comprises, on its inner walls, a thread, and the end 41 is provided with parts inserted in this thread.

The bearing surface 25 is arranged to, under the pressure, reduce the internal volume of the bag 2 by moving towards the bottom wall 21 the distribution piece 23 and the housing member 30, so that the dispensing end 41 slides by pivoting (due to the thread) into the limb housing 30 by sinking into the limb housing 30.

The bearing surface 25 is arranged to, under the effect of pressure, reduce the internal volume of the bag 2 by moving the dispensing piece 33 towards the bottom wall 21 so that the member 31 pivots on itself and that the through hole 33 of the stop 32 faces the through hole 34 of the supply duct 6, at least a time (for example the time that the pressure inside the pocket 2 falls back to a certain level).

A third device embodiment 103 according to the invention will now be described, with reference to FIGS. 18 to 21, solely for its differences with respect to the embodiment of FIGS. 12 to 14.

In the device 103, the stop 32 is not a stopper, but includes one or more openings 40 for the passage of the fluid.

The device 103 comprises a rod 36.

The recharge connector 35 is arranged to:

- When a connection of the charging connector 35 to a source 42 of fluid to be dispensed, push the rod 36 to a location upstream of the dispensing valve 5 (upstream of the dispensing valve 5 means along the a fluid circulation path between the connector 35 and the valve 5) so as to block a flow of fluid upstream of the dispensing valve 5, preferably so as to plug respectively the supply port 124 and / or the dispensing orifice 108, and

when disconnecting the source 42 from the charging connector 35, pulling the rod 36 so that the rod 36 no longer blocks a flow of fluid upstream of the dispensing valve 5, preferably so as to open respectively supply port 124 and / or dispensing orifice 5.

The rod 36 passes through the supply duct 6 and / or the fluid reservoir

13.

More specifically, the charging connector 35 is arranged to, when connecting the recharging connector to a source 42 of fluid to be dispensed, push the rod 36 (which may be a piston 36) towards the orifice 124 so as to plug the orifice 124 by the rod 36 and / or the stop 32.

One end of the rod 36 carries a plug 74. Thus, more exactly, in this embodiment, the charging connector 35 is arranged to, during a connection of the recharging connector to a source 42 of fluid to be dispensed, push the rod 36 against the stop 32 so as to:

- hold the stop against the supply port 124 and

- plug the supply port 124 by the rod 36, more precisely by the plug 74.

Thus, it is possible to recharge the reservoir 13 without the fluid being recharged starting in the pocket 2 or to the outlet 24 under the effect of the pressure of the refill.

The rod 36 is located inside the central space 133.

The charging connector 35 is arranged to, when disconnecting the source 42 to the charging connector 35, pull the rod 36 so that the rod 36 moves away from the orifice 124 and does not plug the orifice 124 .

The charging connector 35 is arranged to, when disconnecting the source 42 to the charging connector 35, pull the rod 36 so that the rod 36 no longer touches the stop 32 and no longer blocks the displacement of the stop 32 .

The bag 2 initially comprises a vacuum or a depression with respect to the contents of the tank 13.

The device 103 may comprise a cap or a stopper (impervious to gas and blocking any passage of gas, and not illustrated) so that the stop 32 is located between this cap or cap and the orifice 124.

The bearing surface 25 is arranged to, when pressing on the bearing surface 25, push the member 31 towards the orifice 124 so that the stop 32 pushes the rod 36 and away from the orifice 124 the rod 36.

Thus, the stop 32 is arranged to pierce or open the cap or cap. This is of interest especially when the bag 2 initially contains a vacuum so as to initiate the device 103.

The lower part of the wall 22 is pinched or clamped between the guide element 26 and the bottom wall 21, so that this zone of gripping or clamping of the wall 22 is sealed and does not let fluid pass between the guiding element 26 and the bottom wall 21. Note that this embodiment comprises only one valve 5 between the bag 2 and the outlet 24, as in most of the illustrated embodiments of the present description. With reference to FIG. 22, in an alternative to the embodiments 102 and 103 of FIGS. 12 to 21, the portion 11 of the valve 5 is not clamped solely by the cap 70. In this variant, the valve 5 (More precisely the part 11) is held between the inner walls of the housing 8 by clamping between the cap 70 and the insert 71.

Thus, in this variant, there is the large opening 205 or large housing 62 (for part 11), the small opening 224 or small housing 61 and the element 29 described with reference to FIGS. 1 to 11.

The small opening 224 (or small housing 61) is included inside the large opening 205 (or large housing 62).

The upper part of the wall 22 is pinched or clamped between the insert

71 and the cap 70 so that this clamping or clamping zone of the wall 22 is sealed and does not let fluid pass between the insert 71 and the cap 70.

The wall 22 is an independent piece without continuity of material with the distribution piece 23.

For the manufacturing method according to the invention of this variant, the valve 5 is placed on the insert 71, which comprises a device 72 for wedging or holding (typically a pin, a cavity, a dovetail or a light tightening if the valve 5 is moved by sliding perpendicular to the axis of insertion of the insert 71 in the cap 70) this before the insertion and translation in the cap 70 of the assembly formed by the insert 71 and the valve 5.

The top of the device can be removable and fit into the tank 13, in particular the skirt 26 can be cut (do not act as a body and / or tank) and be provided with means of connection to the tank 13.

With reference to FIGS. 23 and 24, a fourth device embodiment 104 according to the invention will now be described. only for its differences from the embodiment of FIGS. 1 to 3.

The internal volume of the bag 2 is delimited at least in part by the deformable wall 22 and by the bottom wall 21.

The bottom wall 21 is the ideal surface of a nozzle 89 also called "eye" 89. The device 104 comprises the reservoir 6, 13 delimited by the walls 14 that are fixed to the nozzle 89, or more precisely a bag 14 flexible welded to the nozzle 89.

The device 104 includes the supply port 124 connecting the reservoir 13 to the internal volume of the bag 2.

The bag 2 is located inside the tank 13.

The dispensing part 23 carries the dispensing orifice 108 and is at least partly inserted into the nozzle 89 d on the side of its dispensing orifice 108.

The device 104 comprises the bearing surface 25. The surface 25 is arranged to, under the application of pressure (and contact between the surface 25 and the wall 22, without passing through the disassembling part 23), iminute the volu me inside the pocket 2 by deforming the wall 22 deformable.

The bearing surface 25 does not surround the outlet 24.

The outlet 24 is arranged to dispense fluid in a direction substantially parallel to the bearing surface 25.

The disassembly piece 23 is not located on an apex of the concave shape of the deformable wall 22, that is to say on the upper part of the wall 22.

The bearing surface 25 is arranged to, under the pressure of a pressure, iminute the internal volume of the bag 2 by deforming (and moving) the deformable wall 22 without moving the dispensing housing 8 and the valve. disassembly 5 in the direction of the bottom wall 21.

The housing 8 extends along an axis perpendicular to an axis q ui successively passes through the deformable wall 22, the pocket 2 and the bottom wall 21. The housing 8 is part of the dis tribution piece 23 that is placed or nest on the inside of the eye 89. The supply valve 4 is in the bag 2 and the dispensing valve 5 is in the dispensing piece 23.

The dispensing valve 5 is connected to the supply valve 4 with a "passage channel 111" at the junction zone, more precisely a groove 111 in the valve is connected to the groove 88 or 18 in the housing 8 (We can reverse the realization of the grooves on the flexible part or rigid part, the seal is achieved by crushing the flexible part).

The dispensing valve 5 is held by clamping in the dispensing channel, between portions of the walls of the dispensing channel which surround the groove 88 or 18.

The dispensing valve 5 comprises its portion 11 held by clamping between the inner walls of the housing 8 at the large opening 205 (or the large housing 62) and by clamping a flange 76 parallel to the direction of elongation of the housing 8, typically by clamping between the piece 23 and other piece of the device 104 as for example a part integral with the bottom wall 21, more precisely the eye 89. The flange 76 does the trick except at the passage of the liquid, it allows a seal between parts 89 and 23; alternatively, this seal can also be obtained by clamping or welding between the two parts 89 and 23.

A plug 77 is arranged to pass between two positions:

a first piece 81 comprising the bottom wall 21 and the supply orifice 124, and optionally the valve 4; if present, the valve 4 is mounted against the supply port 124; the wall 21 is arranged so that only two exits allow access to the interior of the tank 13: the orifice 124 and a filling hole 79.

a second piece 82 comprising the wall 22, and also preferably a periphery 80 disposed around the wall 22.

The interior volume of the tank 6, 13 is delimited at least in part by:

- the tank walls 14 and

- the bottom wall 21.

One of the tank walls 14 and the bottom wall 21 is assembled (for example by a flexible tongue) to the deformable wall 22 in a single piece of a single material, that is to say:

the reservoir walls 14 and the deformable wall 22 are assembled in a single piece of a single material (in the case of FIG. 29 and FIG. 30), or

- The bottom wall 21 and the deformable wall 22 are assembled in a single piece of a single material (case of Figure 32).

The supply orifice 124 and the valve 4 in this orifice 124 can be replaced respectively by the supply orifice 124b (slightly offset on the wall 21 with respect to 124) and the valve 4b integral with the wall 22.

The invention relates to a method for producing an ispositif according to the invention, in which the tank 13 is filled with the fluid to be dispensed (preferably liquid or cream or gel or paste or a mixture of these) by filling means.

The bag 2 can communicate with the outside of the container so that the gas contained in the bag 2 can be expelled easily outwardly until the product is raised downstream of the feed hole 124. 124b in two ways:

either during filling with the deformable wall 22 open (filling under pressure or not)

or if the wall 22 is closed (other variant) with a pressure on the reservoir and / or a pressure filling associated with means so that the dispensing valve is in the open or quasi-open position, so that the air can easily come out with a slight gas overpressure in the pocket 2. There are therefore means for reducing the closing force of the dispensing valve, for example in the case of FIG. 41 or 42 it is sufficient to have an external tool which will push the rod 58 towards the inside of the pocket 2.

There are means not shown for pressing the reservoir and / or opening and / or pressing the dispatcher valve 5.

before assembling the deformable wall 22 and the bottom wall 21, so that during filling:

the fluid filling reservoir 13 penetrates through hole 79 but can not leave reservoir 13 through hole 79 (for example by having no interstitial space between the fluid filling means inserted into the hole 79 and the perimeter of this hole 79) the gas initially inside the reservoir 13 can not leave the reservoir through the hole 79 (for example by having no interstitial space between the fluid filling means inserted in the hole 79 and the periphery of this hole; hole 79)

the fluid filling the tank 13 and the gas initially inside the tank 13 can escape from the tank 13 only through the supply orifice 124 or 124b

- and preferably the pocket 2 is not yet formed so that the valve 5 or any other part does not block the fluid outlet by the valve 4.

- Optionally if the bag 2 is closed a tool can come to open the dispensing valve 5 so as to facilitate the expulsion of air outside the device

This filling is carried out until the fluid to be dispensed goes beyond the valve 4 and / or the supply port 124 with respect to the reservoir 13 or reaches the interface between the valve 4 and the seat. 'food .

In the variant where the bag 22 is closed, the filling hole 79 is not covered by the solder of the deformable bag 22 but can be closed by the welding of a tab 99 coming from molding with the deformable bag 22 after filling . Advantageously, the filling hole 79 may be connected to a filling channel protruding from the bottom wall 21. In another variant, the bottom wall 21 has a skirt forming a lateral part of the reservoir 6, on this skirt is disposed the hole filling member 79 which can be closed by the tongue 99 of the wall 22 and making an angle of the order of 90 ° with the bottom wall 21.

At a second end of this valve tube is the valve 4, comprising two tongues arranged to approach one another in the open position of the valve 4.

The device 335 is eq uiped (preferably on the nozzle 89) of a plug 310 blocking an orifice opening on the inside of the reservoir 13. This plug 310 serves to fill the reservoir 13.

With reference to FIG. 51, part 23 forms a spout 311 in which housing 8 is located.

The spout 311 carries a tongue 314, also called abutment member 314. The element 314 is substantially perpendicular to the spout 311.

The part 23 and the reservoir 13 is mounted inside a housing 312, 313. This housing is formed by two parts respectively 312 and 313.

The piece 312 is made of a material without discontinuity of material.

The piece 312 comprises a wall 316 running along the outside of the wall 14.

The piece 312 comprises a head 315.

The part 313 comprises a wall 321 running along the outside of the wall 14.

The spout 311 is inserted into the head 315 by the inside of the housing 312, 313 before assembly of the two parts 312 and 313. After the insertion of the spout 311 in the head 315, the two parts 312 and 313 are assembled from in order to enclose the part 23 and the reservoir 14. Thus, the element 314 is held between the head 315 and on the other side the wall 321 and / or the part 89. An applicator 317 is mounted (typically clipped) on the head 315.

The seal 318 may be integral with and / or overmoulded on the head 315 or the applicator 317.

The applicator 317 is clipped to the head 315. The applicator 317 comprises one or more buttons 331 arranged to unclip the applicator 317 with respect to the head 315.

In a non-gloss variant, the pocket 2 is formed by the same part as the end piece 89 and / or the allocation piece 23, without discontinuity of material. For example, the pocket 2 can be formed:

by a rigid or flexible bottom wall 21 integral with the end piece 89 and / or the distribution piece 23, without any continuity of material, and

by a flexible wall 22 (thin thickness) integral with the bottom wall 21 without discontinuity of material, and connected to the bottom wall by a plyure 307 as in the case of the preceding FIG. 47. However, unlike FIG. 47, the fold 47 is preferably located opposite the end piece 89 relative to the pocket 2.

In a non-illustrated variant of FIG. 49, the outlet 24 is widened so as to have a cross-sectional area or a diameter equivalent to that of the housing 8. In this variant, the valve 5 can be inserted in the housing 8 by the In addition, the device 335 can be filled with fluid by filling the outlet 24 by filling all or part of the reservoir 13 and all or part of the bag 2 before inserting the valve 5 in the housing 8. This allows to improve the priming of the device 335. In this case the valves 4 and 5 are illustrated in Figure 50b, and the device is without groove / channel 18 on the housing 8. In this case the piece forming the valves 4, 5 has a hump 337 or a clip 337 which comes to put in the (s) hole of admission 124.

The plug 351 blocks the interface between the outside of the device according to the invention and the pocket 2.

In a variant not shown, the part 23 may be in two parts separating the valves 4 and 5, these two parts being connected by a sealed connector which can be in the room 89. These two parts can be nested in a non-removable manner. Preferably the spout which contains the dispensing valve 5 is in one part. The filling can be done before the connection of the dispensing valve.

This distribution piece 23 may be arranged to be mounted in a hood or protective cap. Thus it can be connected after filling at the same time as the installation of the cap or protective cover. The connection may be arranged so that it can no longer be dismounted at the end of the connection operation after the filling / closing the hood-protective cap. This is true also in the case of the valve. The beak may be replaced by a head. The dispatcher 23 closes / closes the pocket 2.

The wall 22 is in a bag 14.

It will be seen in FIG. 49 that the product (fluid) to be dispensed is moving back and forth in the same inlet and outlet port of the bag 2 to enter and exit the bag.

Referring now to FIG. 53, a housing variant 8 can be described which can replace the housing 8 of each of FIGS. 1 to 40 and 44 to 47 and 57 to 58, solely for its differences with respect to the mode of operation. realisation of Figure 28.

In this variant, the housing 8 comprises an angular point 320 in contact with the wall of the cavity 121, arranged to create a lateral compression zone of the cavity 121. This improves the sealing of the valve 5.

With reference to FIGS. 54 to 56, a sixth embodiment of the device 106 according to the invention will now be described only for its differences with respect to the embodiment of FIG. 33.

In this embodiment, the bearing surface 25 is arranged so that a support (it shine in FIG. 55) on the surface 25 deforms the wall 22 by crushing the wall 22.

A rigid element 322 (typically a tube) relies on the bottom wall 21 and the disassembling part 23 and is arranged to smooth the translation of the part 23 with respect to the bottom wall 21.

The element 322 is integral with the wall 21. The element 322 and the wall 21 are in one and the same piece without discontinuity of material.

The element 322 enters the part 23 and is arranged to slide in the part 23 (more exactly in the insert 71).

A spring or return means 323 (optional) is arranged to return the valve 5 from its open position to its closed position. The biasing means 323 comprises a deformable ring surrounding the element 322 and compressed between the piece 23 (more exactly the insert 71) and the valve 5 when the valve 5 is in its open position.

The valve 5 comprises a movable element, preferably a rigid or semi-rigid ring, surrounding the element 322. In the closed position of the valve 5 (FIG. 54), the valve 5 blocks a channel connecting the bag 2 to the outlet 24. In the open position of the valve 5 (Figure 55), the valve 5 is moved so as not to plug this channel connecting the bag 2 to the outlet 24; more exactly, it is moved:

sliding in the piece 23 (more exactly in the insert 71) while approaching the exit 24

sliding around the element 322 while approaching the bottom wall 21.

What moves the valve 5 is the relative friction between on the one hand the valve 5 and the part 23 (more exactly the insert 71) and on the other hand between the valve 5 and the element 322. Preferably the friction is more important on the element 322 so as to have an easier movement of the valve 5 in the insert 71 to open the orifice 712 in the insert 71 (the overpressure also contributes to the displacement of the valve 5). The orifice 712 is lateral with respect to the element 322. When pressing on the bearing surface 25, the liquid of the bag 2 circulates between the element 322 and the insert 71 and then passes laterally into the port 712 away from the center of the device or the element 322 and follows a path substantially parallel to the axis 322 (outside 322).

An attachment ring 324 surrounding the wall 21 holds the bottom wall 21 to the reservoir 13 by clamping.

A duct 325 connecting the inside of the tank 13 to the outside of the device 106 without passing through the bag 2 makes it possible to balance the pressures between the inside of the tank 13 and the outside of the device 106 when the valve 5 is in position. open position, this duct 325 being open (Figure 55) when the valve 5 is in its open position. This duct 325 is closed

(FIG. 54) when the valve 5 is in its closed position, this duct 325 (more exactly the hole 712) being then obstructed by the valve 5.

The wall 22 is visible by a user from outside the device 106. The device 106 works even if a little support on the head, in this case the valve 5 can be opened.

The device 106 comprises a locking device:

- A relative position of the cap 70 and the insert 71 is such that the insert 71 closes the channel 330 connecting the valve 5 to the outlet 24 at an interface between the cap 70 and the insert 71 (position taken from the headdress or head), and

A relative position of the cap 70 and the insert 71 is different in the case where the valve 5 is closed and is such that the insert 71 no longer closes the channel 330 connecting the valve 5 to the outlet 24 at a interface between the cap 70 and the insert 71 (depressed position of the head or cap)

The valve 5 is arranged to remain open (with a minimum opening of 1 mm ² for at least 0.5 seconds) without necessarily requiring overpressure greater than 0.2 or 0.5 bar in the pocket 2 relative to the outlet 24.

The wall 22 and / or the insert 71 and / or the ring 324 may be manufactured in the same piece, for example with overmolding, and therefore be integral. The ring 324 may be aimed or clipped.

The feed tube 334 is preferably located towards the center, a channel 332 connects the tube 334 with valve 4, in the bottom wall 21. This channel 332 is plugged laterally by a portion of the bag 2 and / or the ring 324.

In contrast to FIG. 33 for which the guide 26 was external to the part 23 or the insert 71, in the case of FIG. 54 the guide means 26 are internal to the part 23 or the insert 71, and are preferably formed by the element 322 sliding in the insert 71.

The channel 332 in the bottom wall 21 is arranged to center relative to the reservoir 13 to within plus or minus 5 mm the position of the tube 334 immersed in the reservoir 13 and connecting the reservoir 13 to the pocket 2, despite the existence of the tube 322 also centered.

It is thus noted that this embodiment of the device according to the invention comprises the rigid element 322 connecting the bottom wall 21 and the distribution piece 23 and arranged to guide a translation of the piece of distribution 23 relative to the bottom wall 21, the dispensing valve 5 being arranged to slide by friction around the rigid element 322 so that in the open position of the dispensing valve 5 the dispensing valve releases a passage of the fluid to be distributed along a lateral channel (more exactly the opening 712 of this lateral channel) located in the dispensing part 23 and connecting the bag 2 to the outlet 24.
