These embodiments being in no way limitative, it will be possible in particular 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 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 characteristic, preferably functional, without structural details, and / or with only part of the structural details if this part only is sufficient to confer a technical advantage or to differentiate the invention from the state of the art. earlier.
- We will first describe, with reference to Figures 1 to 3, a first embodiment of device 101 according to the invention for dispensing a fluid.
Unless otherwise stated and in a purely illustrative manner:
- each valve of device 101 (preferably flexible) is typically made of thermoplastic elastomer (TPE) or a polyurethane thermoplastic elastomer of 80 Shore A, all the other parts of device 101 (typically rigid or semi-rigid) are made of polypropylene (abbreviated by PP in the remainder of this description).
The fluid comprises a liquid and / or a gas, and is preferably a liquid, a cream, a paste, a gel or a mixture of the latter.
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 displacement or mobility relative to the bottom wall 21.
The wall 22 forms a skirt and has an upper part and a lower part.
The deformable wall 22 (more precisely its lower part) is fixed or welded to the bottom wall 21.
The bottom wall 21 preferably has the shape of a plane or substantially of a plane.
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 thicker wall than the wall 21.
The walls 21 and 22 are for example made of polypropylene.
The wall 22 is preferably made of 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. Consequently, excessively fine smoothness and fragility of the wall 22 are avoided.
The device 101 comprises a distribution piece 23 comprising a distribution housing 8.
The device 101 comprises a bearing surface 25 arranged to, under the exercise of pressure and through the dispensing part 23, reduce the internal volume of the pocket 2 by deforming the deformable wall 22.
The bearing surface 25 is integral with the distribution piece 23, and preferably comprises at least part of the distribution piece 23.
The device 101 includes an output 24.
The outlet 24 opens onto 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 pocket 2 to the dispensing housing 8.
The device 101 comprises a dispensing valve 5 located in the dispensing housing 8, and which in an open state, allows a passage of fluid from the interior of the bag 2 to the outlet 24 passing through the dispensing orifice 108 and through the distribution housing 8, and, in a closed state, does not allow a passage of fluid from the interior of the bag 2 to the outlet 24 passing through the distribution orifice 108 and through the distribution housing 8 .
The distribution piece 23 is integral with the deformable wall 22.
The distribution piece 23 is located on a vertex 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 part 23 and the wall 22, it is noted that the wall 22 is thicker than elsewhere in particular than 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 pressing 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 can carry several distribution 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 exercise of pressure, reduce the interior volume of the pocket 2 by deforming (and moving) the deformable wall 22 while moving the distribution housing 8 and the valve distribution 5 towards the bottom wall
21. The direction of the liquid is opposite to the direction of support on the device, and is even central.
By making the distribution piece 23 and the deformable wall 22 integral, the compactness of the device is considerably improved, as well as its simplicity of use and manufacture.
The housing 8 extends along an axis which 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 piece 23 are grouped 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 lower than 1000 MPa.
The bearing surface 25 is arranged to, under the exercise of pressure, reduce the interior volume of the pocket 2 by deforming the deformable wall 22, more precisely by crushing it in the direction of the bottom wall 21. The liquid distribution direction is opposite to the direction of support on the support 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, 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 is not subjected to any external stress, it resumes or remains in its shape (preferably concave) which maximizes the volume of the bag 2.
The distribution piece 23 is located outside of 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 distribution part
23.
The crown 28 is for example made of PP. The product leaves at the level of the distribution ring 28, the distance between the closure of the valve (more precisely the distribution seat 105) and this distribution ring and at a distance of less than 6 mm.
The bearing surface 25 is located partly on the dispensing part (around the outlet 24) and on an external surface of the ring 28.
This support surface 25, accessible from outside the device 101 by a hand of a user, has a minimum surface of 20 mm ² .
The distribution housing 8 comprises a small opening 224 (or respectively a small housing 61) of the distribution housing 8 on the side of the outlet 24 which has an area (or respectively a volume) smaller than a large opening 205 (or respectively large housing 62) of the distribution housing 8 on the side of the distribution orifice 108.
The distribution housing can include 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 side of the outlet 24 has an area at least two
- 18 times smaller than the large opening 205 of the distribution housing 8 on the side of the distribution 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 done by a step or filling element 29 of the housing 8. It is noted that this step 29 in the distribution channel is connected to outlet 24 and is downstream of the distribution valve 5 (unlike the stem valve, the reduction in section is before the valve closes).
The filling element 29 is typically the imprint of the valve 5 with a space ranging from 0 to 0.5 mm, possibly less the cylindrical passage which connects the outlet to the outlet housing (cylinder).
The filling element 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 of the outlet 24, and to improve hygiene
The distribution valve 5 comprises a part 11 held by clamping between internal walls of the housing 8 at the level of 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 part 11 and the internal walls of the housing 8 at the level of the large opening 205 (or respectively large housing 62).
The dispensing valve 5 comprises a movable part 12 which, in the closed state of this dispensing valve 5, is pressed against a dispensing seat 105 so as to block this dispensing seat 105, and in the open state of this dispensing valve 5, moves away from the dispensing seat 105 so as to open this dispensing seat 105.
This part 12 is a membrane or lamella.
The dispensing valve 5 comprises a part 12 inserted in the small opening 224 (or respectively in the small housing 61). This part 12 is the movable membrane 12 of the valve 5. The part 12 is located
- 19 in the small housing 61 and the part 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 it "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.
We also note that the distribution seat 105 is a lateral part of the internal walls of the housing 8, that is to say that this seat 105 is limited to one face, preferably flat (or curved), of the internal walls of the housing 8, and does not go all the way around a section of housing 8 which would be produced in a plane perpendicular to the direction of elongation of the part of housing 8 containing the valve 5. Housing 8 includes a passage groove 88 , the dispensing seat partially surrounds this groove 88, the part 11 closes the groove 88 to form a sealed passage.
The device 101 comprises a supply conduit 6 merged (as illustrated in the figures) or connected with a reservoir 13 of fluid.
The conduit 6 and / or reservoir 13 is delimited at least in part by a flexible wall 14 or a flexible bag 14, typically made of polyethylene polyethylene terephthalate (PET) / Aluminum / cast polypropylene (PP) film, the layer of PET being towards the outside of the bag 3.
The device 101 comprises a supply orifice 124 connecting the supply duct 6 to the interior volume of the bag 2.
The device 101 comprises a supply valve 4 which, in an open state, allows a passage of fluid from the supply duct 6 towards the interior of the bag 2 passing through the supply orifice 124, and, in a closed state, does not allow a passage of fluid from the supply conduit 6 towards the interior of the bag 2 passing through the supply orifice 124.
The supply valve 4 is located inside the pocket 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 orifice 124.
The supply valve 4 (movable between its closed and open positions) is, in its closed state, kept pressed against a stationary part (called supply seat, which at least partially surrounds the periphery of the supply orifice 124 associated) and “rigid” (ie not made of flexible material) of an internal wall of the pocket 2. More specifically, the supply valve 4 comprises a membrane which, in the closed state of the supply valve 4, is kept 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.

The device 102 comprises guide means 26 arranged to guide a movement 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 distribution part 23 (also called distribution head 23) comprises:
- a cap 70, and
- an insert 71.
The insert 71 is inserted into the cap 70.
There is a continuity of material between the deformable wall 22 and at least one part (more precisely the cap 70) of the distribution piece
23. The wall 22 and at least a part (more precisely the cap 70) of the part 23 are grouped into a single part of the same material without discontinuity of material, for example PP.
The housing 8 is located inside the at least one part 70 (of the distribution piece 23) having a material continuity with the wall
22.
The valve 5 is located inside the at least one part 70 (of the distribution piece 23) having a material continuity with the wall 22.
The connection between the cap 70 and the insert 71 is sealed so as to have a pocket 38 of sealed air or gas. 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 distribution part 23 (more precisely the insert 71) comprises a member housing 30.
The dispensing end 41 is housed inside the member housing 30.
The dispensing end 41 is arranged to slide inside the member housing 30
The feed end 51 carries the feed valve 4.
The member housing 30 comprises at least one lug or relief 37 arranged to block the sliding of the member end 41 in the member 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 exercise of pressure, reduce the interior volume of the pocket 2 by moving the distribution part 23 and the member housing 30 in the direction of the bottom wall, so than :
- The dispensing end 41 slides in the member housing 30 while sinking into the member housing 30; taking into account the lug or relief 37 (which is optional) and / or the friction between the internal walls of the member housing 30 and the end 41 and / or a 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 making it possible to avoid the stop 32 described below), the member 31 also moves in the direction of the bottom wall but with a lower range of motion the amplitude of movement of the part 23 and of the housing 30; and
- the member 31 presses the supply valve 4 in its closed position against the supply orifice 124, at least for a time (typically the valve 4 begins to rise at the start of the race, then is pressed against the orifice 124 until the pressure inside the pocket 2 drops to a certain level). This makes it easier to start the device 102.
The dispensing end 41 is split lengthwise.
The device 102 comprises a stop 32 located inside the supply duct 6.
The stop is arranged to press against the supply orifice 124 or at least be close to the supply 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 that 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 being subjected to external stress or force, the stop 32 is pressed against the supply orifice 124. The bearing surface 25 is arranged for, under the pressure, decrease the interior volume of the pocket 2 by moving the dispensing part 23 (and the member housing 30, so that the dispensing end 41 slides in the member housing by sinking into the member housing) so that the member 31 moves its stop 32 away from the supply port 124.
In this embodiment, the housing 8 has the shape of a letter T. The distribution valve 5 is located in the upper bar of the T. The distribution valve 5 is located in the cap 70.
The seat 105 is located in the cover 70.
The part 11 of the valve 5 is held by clamping between the internal 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" into which the fluid to be dispensed can not penetrate.
This also makes it easier to start the device 102.
This area 38 is for example an air cavity or an area filled with material, for example PP.
Thus, the housing 30 is surrounded, within a 360 ° perimeter 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 of T) of the housing 8. This channel 56 is also located in the cap 70, but could in a variant be found in the insert 71.
The reservoir 13 is not formed by a flexible bag but not rigid PP walls.
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 distributed 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 whatever the position of the piston 32.
The device 102 comprises a recharging connector 35 arranged to allow the recharging of fluid inside the device 102 (more precisely inside the conduit 6 and / or reservoir 13) without this fluid passing through the pocket 2 or the distribution valve 5 or the supply valve 4.
The connector 35 includes a charging 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 have a spring effect.
In one embodiment of the method for manufacturing the device 102, the distribution valve 5 is mounted in the distribution housing 8 by insertion through the outlet 24.
This makes it possible to have a one-piece 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 being deformed.
We will now describe, with reference to FIGS. 15, 16 and 17, a variant of the second embodiment of device 102 according to the invention, only for its differences from 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 circulation of fluid through the supply orifice 124 as long as the passage hole 33 of the stop 32 does not face the passage hole 34 of the supply duct
6.
The through hole 33 of the stop 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 internal walls, a thread, and the end 41 is provided with parts fitting into this thread.
The bearing surface 25 is arranged to, under the exercise of pressure, reduce the interior volume of the pocket 2 by moving towards the bottom wall 21 the distribution piece 23 and the member housing 30, so that the dispensing end 41 slides by pivoting (due to the thread) in the member housing 30 by sinking into the member housing 30.
The bearing surface 25 is arranged to, under the exercise of pressure, reduce the interior volume of the pocket 2 by moving the dispensing part 33 towards the bottom wall 21 so that the member 31
-29pivots on itself and that the passage hole 33 of the stop 32 faces the passage hole 34 of the supply duct 6, at least a time (for example the time that the pressure inside the pocket 2 falls to a certain level).
We will now describe, with reference to FIGS. 18 to 21, a third embodiment of device 103 according to the invention, only for its differences compared to the embodiment of FIGS. 12 to 14.
In the device 103, the stop 32 is not a plug, but comprises one or more orifices 40 allowing the passage of the fluid.
The device 103 comprises a rod 36.
The charging connector 35 is arranged for:
- when connecting the refill connector 35 to a source 42 of fluid to be dispensed, push the rod 36 to a location upstream of the distribution valve 5 (upstream of the distribution valve 5 meaning along a fluid circulation path between the connector 35 and the valve 5) so as to block a circulation of fluid upstream of the distribution valve 5, preferably so as to block respectively the supply orifice 124 and / or the dispensing orifice 108, and
- when the source 42 is disconnected from the refill connector 35, pull the rod 36 so that the rod 36 no longer blocks a flow of fluid upstream of the distribution valve 5, preferably so as to open respectively l supply port 124 and / or distribution port 5.
The rod 36 passes through the supply conduit 6 and / or the fluid reservoir
13.
More specifically, the refill connector 35 is arranged to, when connecting the refill 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 with the rod 36 and / or the stop 32.
One end of the rod 36 carries a plug 74.
Thus, more precisely, in this embodiment, the charging connector 35 is arranged so that, when the charging connector is connected to a source 42 of fluid to be distributed, push the rod 36 against the stop 32 so as to:
- maintain the stop against the supply port 124 and
- plug the supply orifice 124 with the rod 36, more precisely with the plug 74.
Thus, the reservoir 13 can be recharged without the fluid being recharged going into 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 so that, when the source 42 is disconnected from the charging connector 35, pull the rod 36 so that the rod 36 moves away from the orifice 124 and does not block the orifice 124 .
The charging connector 35 is arranged so that, when the source 42 is disconnected from the charging connector 35, pull the rod 36 so that the rod 36 no longer touches the stop 32 and no longer blocks movement of the stop 32 .
The bearing surface 25 is arranged to, when pressed on the bearing surface 25, push the member 31 in the direction of the orifice 124 so that the stop 32 pushes the rod 36 and moves away from the orifice 124 the rod 36.
The lower part of the wall 22 is pinched or clamped between the guide element 26 and the bottom wall 21, so that this pinching or clamping zone of the wall 22 is sealed and does not allow any fluid to pass between the guide element 26 and the bottom wall 21.
With reference to FIG. 22, in a variant of embodiments 102 and 103 of FIGS. 12 to 21, the part 11 of the valve 5 is not held by tightening only by the cap 70. In this variant, the valve 5 (more precisely part 11) is held between internal walls of the housing 8 by clamping between the cap 70 and the insert 71.
We thus find in this variant the large opening 205 or large housing 62 (for the 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 pinching or clamping zone of the wall 22 is sealed and does not allow fluid to 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 slight 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 the translation in the cap 70 of the assembly formed by the insert 71 and the valve

- either during filling with the deformable wall 22 open (filling under pressure or not)
- Either if the wall 22 is closed (another variant) with pressure on the tank and / or filling under pressure associated with means so that the dispensing valve is in the open or almost open position, so that the air can easily exit with a slight gas overpressure in the pocket 2. We therefore have means to reduce the closing force of the dispensing valve, for example in the case of FIG. 41 or 42, it suffices to have a tool external 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 dispensing valve 5.
before assembling the deformable wall 22 and the bottom wall 21, so that during filling:
- the fluid filling the reservoir 13 penetrates through the hole 79 but cannot leave the reservoir 13 through the hole 79 (for example by having no interstitial space between the fluid filling means inserted in the hole 79 and the around this hole 79)
- the gas initially inside the reservoir 13 cannot exit 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 79)
the fluid filling the reservoir 13 and the gas initially inside the reservoir 13 can escape from the reservoir 13 only through the supply orifice 124 or 124b
- and preferably the bag 2 is not yet formed so that the valve 5 or any other part does not block the outlet of fluid through the valve 4.
- optionally if the bag 2 is closed, a tool can open the distribution 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 orifice 124 relative to the
Reservoir 38 or reaches the interface between valve 4 and the supply seat.
In the variant where the pocket 22 is closed, the filling hole 79 is not covered by the welding of the deformable pocket 22 but can be closed by the welding of a tab 99 coming from molding with the deformable pocket 22 after filling . Advantageously, the filling hole 79 can be connected to a filling channel projecting from the bottom wall 21. In another variant, the bottom wall 21 has a skirt forming a lateral part of the tank 6, on this skirt is arranged the hole filling 79 which can be closed by the tab 99 of the wall 22 and making an angle of the order of 90 ° with the bottom wall 21.
Then, in this embodiment of the method according to the invention, the bottom wall 21 and the deformable wall 22 are assembled so as to form the pocket 2 and the hole 79 is plugged. The plugging of the hole 79 and the assembly can be done simultaneously. For example, it is possible to fix (for example by ultrasonic welding) the periphery 80 on the wall 21 so that the fixed periphery 80 blocks the hole 79.
Thus, thanks to this embodiment of the method according to the invention, it is very easy to initiate the passage of fluid to be distributed by the valve 4.
Preferably, the second part 82 also includes the part 23 and / or the housing 8 and / or the valve 5.
The two assembled parts 81, 82 are then enclosed between a mobile distribution wall 83 comprising the surface 25 and a housing 84.
The movable distribution wall 83 comes into contact with the wall 22 and / or the part 23.
Feet or ribs 85, integral with the first part 81 and / or the housing 84, are arranged to maintain the position of the wall 21 fixed relative to the housing 84, even in the event of a reduction in the volume of the reservoir 13 following an exit fluid out of reservoir 13.
In this variant of device 101, the device 101 comprises the crown 28.
The distribution ring 28 is superimposed on the wall 22, and is preferably fitted or clipped onto the distribution piece 23 via a connection stud 231 secured to the wall 22 and / or to the piece 23 as
In the case of FIG. 4. (In a less preferential manner, it is possible to reverse: the connection stud 231 can be on the distribution ring 28 and this stud enters the distribution piece 23). With reference to FIG. 31, it is noted that the width d of the stud 231 is smaller than the width e of the part 23 preferably by a factor of at least 1.5 times less d <1.5e
The bearing surface 25 is located on this ring 28.
The interior volume of the pocket 2 is delimited at least in part by the deformable wall 22 and by the bottom wall 21.
The device 101 comprises the reservoir 13 delimited by the reservoir walls 14 and the bottom wall 21.
Before assembly of the wall 22 and the wall 21, the bottom wall 21 is arranged so that only two exits allow access to the interior of the reservoir 13: the supply orifice 124 and the filling hole 79 .
At least one of the tank walls 14 and the bottom wall 21 is assembled to the deformable wall 22 in a single piece.

The charging connector 35 is arranged for:
- when connecting the refill connector 35 to a source 42 of fluid to be distributed, push the rod 36 so as to move the seal 39 away from the connector 35 so as to create an opening for the passage of fluid from the source 42 towards the inside the tank 13 (more precisely towards the inside of the space 133), and
- when the source 42 is disconnected from the charging connector
35, that a spring 86 or other return means pushes the rod 36 so as to bring the seal 39 towards the connector 35 so as to close the opening for the passage of fluid from the source 42 towards the interior of the reservoir 13 ( more precisely towards the interior of space 133).
