[0256] These embodiments being in no way limiting, variants of the invention may be considered, in particular, comprising only a selection of features described or illustrated hereafter, isolated from the other features described or illustrated (even if this selection is isolated within a sentence including these other features), if this selection of features is sufficient for to confer a technical advantage or to differentiate the invention from the prior art. This selection includes at least one preferably functional feature without structural details, and / or with only some of the structural details if that part alone is sufficient to confer a technical advantage or to differentiate the invention from the prior art. Preferably, the product to be dispensed is a fluid.

[0257] We will first describe, with reference to figures 1 to 3, a first embodiment of device 101 according to the invention for distributing a fluid.

[0258] Unless otherwise stated and for illustrative purposes only: - Each valve of device 101 (preferably flexible) is typically made of thermoplastic elastomer (TPE) or (TPO) - all other rigid parts of device 101 are made of polypropylene or polyethylene - the reservoir can be a multilayer film composed of different materials, or preferably materials in the polyolefin family.

[0259] The fluid comprises a liquid and / or a gas, and is preferably a liquid, a cream, a paste, a gel or a mixture thereof.

[0260] The device 101 for distributing a fluid comprises a pouch 2 having an internal volume arranged to contain the fluid, the internal volume being delimited at least in part by a deformable wall 22. The deformable wall is optional. Generally, it is referred to as a movable wall 22, since it is the pouch itself that is deformable, whether by a deformable wall or by rigid walls having relative movement such as in a piston.

[0261] The pocket 2 is formed by a bottom wall 21 (also called pocket wall 21) and by the flexible deformable wall 22.

[0262] The pocket walls 21 and the deformable wall 22 face each other.

[0263] The deformable wall 22 has a concave shape oriented towards the bottom wall 21.

[0264] The deformable wall 22 is fixed or welded to the bottom wall 21.

[0265] The bottom wall 21 is a rigid wall, that is to say, more rigid than the wall 22.

[0266] Walls 21 and 22 are for example made of polypropylene or polyethylene.

[0267] The device 101 includes a distribution piece 23 comprising a distribution housing 8. The pocket 2 is connected to the distribution housing 8.

[0268] The device 101 includes a support surface 25 arranged to, under the exercise of pressure, decrease the internal volume of the pocket 2 by deforming the deformable wall 22.

[0269] Device 101 includes an output 24.

[0270] The outlet 24 leads to the outside of the device 101.

[0271] The outlet 24 is preferably located on the distribution part 23.

[0272] The device 101 includes a distribution port 18 or 355 connecting the bag 2 to the distribution housing 8.

[0273] The device 101 includes a distribution valve 5 located in the distribution housing 8, and which, in an open state, allows fluid to pass from inside the bag 2 to the outlet 24 through the distribution orifice 18 and through the distribution housing 8, and, in a closed state, does not allow fluid to pass from inside the bag 2 to the outlet and through the distribution housing 8.

[0274] The bearing surface 25 is arranged so as, under the application of pressure, to decrease the internal volume of the pocket 2 by deforming the deformable wall 22, more precisely by crushing it towards the pocket wall 21

[0275] The distribution piece 23 is arranged so that, by exerting pressure on the bearing surface 25, it moves at least in a translational motion.

[0276] The deformable wall 22 has shape memory. When this wall 22 is not subjected to any external stress, it returns to or remains in its shape (preferably concave) which maximizes the volume of the pocket 2.

[0277] The device 101 includes a supply port 41 connected with a fluid reservoir 6.

[0278] The reservoir 6 is delimited at least in part by a flexible wall 108 or a flexible bag 14, typically a multilayer film.

[0279] The device 101 includes a feed port 41 connecting the reservoir 6 to the internal volume of the bag 2. The port 41 coincides with an opening 124 of the reservoir 6 connecting it to the bag 2.

[0280] The device 101 includes a feed valve 4 which, in an open state, allows fluid to pass from the reservoir 6 into the inside of the pouch 2 through the feed port 41, and, in a closed state, does not allow fluid to pass into the inside of the pouch 2 through the feed port 4L

[0281] The feeding valve 4 is located inside the bag 2 and is arranged to: - In its closed state, press against the feeding port 41, and - In its open state, move away from the feeding port 4L

[0282] The feeding valve 4 (mobile between its closed and open positions) is, in its closed state, held against a stationary (called feeding seat, which at least partially surrounds the periphery of the associated feeding orifice 41) and "rigid" (i.e. not made of flexible material) part of an internal wall of the bag 2. More specifically, the feeding valve 4 includes a membrane which, in the closed state of the feeding valve 4, is held against the feeding seat, and moves away from this feeding seat in its open state.

[0283] The feeding seat is located inside pocket 2, on pocket wall 21.

[0284] At rest, that is to say without the device 101 being subjected to any external stress or force, the valve 5 is in its closed state.

[0285] Preferably, although less essential, at rest, i.e. without the device 101 being subjected to any external stress or force, the valve 4 is also in its closed state.

[0286] When the pocket 2 is filled with fluid to be distributed and the volume of the pocket 2 decreases (for example due to an increase in pressure on the support surface 25): - the distribution valve 5 moves away from the distribution seat 13 and the valve 5 is in its open state; fluid exits through the outlet 24 and the pouch 2 empties at least partially, - the supply valve 4 is pressed against the supply port 41 and the valve 4 is in its closed state; no (or almost no) fluid can escape from the pocket 2 to the reservoir 6.

[0287] When the bag 2 is filled with fluid to be distributed and the volume of the bag 2 increases (for example by releasing pressure on the support surface 25): - The distribution valve 5 presses against the distribution seat 105 and the valve 5 is in its closed state; fluid cannot pass from the pocket 2 to the outlet 24 - the supply valve 4 is "aspirated" and moves away from the supply port 41 and the valve 4 is in its open state; fluid can pass from the conduit 6 to the bag 2 so as to fill the bag 2.

[0288] A distribution channel connects the outlet 24 inside the pocket 2. This distribution channel includes the housing 8.

[0289] The bottom wall 21 is integral with an end piece 89 also called an "eye" 89.

[0290] The device 101 comprises the reservoir 6 delimited by the walls 14, 108 which are attached to the end piece 89, or more precisely a flexible bag 14, 108 welded to the end piece 89.

[0291] Pouch 2 is located inside reservoir 6 or sachet 14.

[0292] The outlet 24 is arranged to distribute fluid in a direction substantially parallel to the support surface 25.

[0293] A plug 77 for blocking outlet 24 is arranged to pass between two positions: - A closed position in which part 771 (nipple) of the plug 77 is inserted into the outlet 24 so as to plug or protect the outlet 24 from dirt, the distance between the closure of the distribution valve 5 and the outlet 24 is less than 6 mm or less than 4 mm. Grooves in the inner perimeter of the outlet 24 allow, when part 771 (nipple) the plug 77 (or generally any valve or plug 77) is inserted into the outlet 24 so as to block or protect the outlet 24 from dirt, prevent the passage of the fluid (liquid, cream or gel) to be distributed but leave a passage of air through the outlet 24; - An open position (illustrated in [Fig.1]) in which this part 771 of the plug 77 is no longer inserted into the outlet 24.

[0294] Pocket 2 is located inside reservoir 6.

[0295] The device 101 includes the feed valve 4 which, in an open state, permits fluid to pass from the feed conduit into the inside of the bag 2 through the feed orifice 41, and, in a closed state, does not permit fluid to pass from the feed conduit into the inside of the bag 2 through the feed orifice.

[0296] The supply valve 4 is integral with the distribution valve 5.

[0297] The supply valve 4 and the distribution valve 5 are in a single piece of a single material.

[0298] Part 23 and pocket wall 21 are in one single piece without discontinuity of material.

[0299] The tip 89 and the part 23 are in one single piece without discontinuity of material.

[0300] We have one or two filling holes 87, 87b each opening onto the inside of the reservoir 6.

[0301] Preferably, there are two of these filling holes, located on either side of outlet 24.

[0302] These filler holes go through part 89.

[0303] A single 310 plug is arranged to simultaneously: - Plug the filling hole(s), and - Plug and / or protect outlet 24.

[0304] The cap 310 includes a cap 77 which is removable by means of a hinge.

[0305] The cap 310 comprises two cylindrical pins 313 that fit into the nozzle 89 with a slight tightening (preferably with a snap-fit) at the filling holes 87 and 87b in order to precisely adjust and hold the cap 310 with the nozzle 89 during assembly. This is the predominant fastening means in assembling the cap 310 onto the nozzle 89; additional independent clips further secure the assembly. The diameter of the pins 313 is preferably greater than 3 mm and even greater than 4 mm. Preferably, the two holes 87 and 87b are through holes, however, in a non-through version represented one of the holes 87 or 87b is non-through, this non-through hole is called an adjustment or positioning hole.

[0306] The nozzle 89 includes two lateral notches 130 arranged to retain the device during filling and / or closing by inserting the cap 310 into this nozzle 89. Typically, the nozzle 89 is arranged to slide into rails of a packaging device. The notches are located on the lateral ends of the nozzle 89 towards the lateral edges of the reservoir 14.

[0307] The plug 310 includes a housing 312 arranged to receive the end of the distribution piece 23 having the outlet 24. The distribution piece 23 passes through the plug 310.

[0308] Figures 3a and 3b are two variants of the cap 310 of the device 101. In these variants, the cap 310 includes an applicator 208 formed in the cap (at least in part) with a domed shape 308 or with a beak shape 309. The housing 312 is located in the applicator 208 and is arranged to receive or fit with the dispensing piece 23. The housing 312 surrounds at least in part the dispensing valve 5 and / or the dispensing housing 8.

[0309] The bag 14 is welded to the eye 89, more precisely to fins. In another embodiment, the eye includes a welding wall extending along the axis of the distribution channel 114; the cavity formed between the welding wall and the distribution piece 23 is hidden by the plug 310.

[0310] With reference to [Fig. 3a], the applicator 208 comprises a domed shape 308 at least 4 mm thick and even at least 8 mm thick, allowing the product or fluid to be dispensed to be spread and / or a part of a body to be massaged with the product or fluid to be dispensed. A removable cover (not shown) protects the applicator 208. This applicator may include, at the outlet 24 or the orifice 24, a layer 315, which may be a metallic layer, a foam layer, or a fabric layer. This layer 315 covers the orifice 24 if, for example, it is made of foam or fabric. The device may include several orifices 24. At least one orifice 24 may be covered by this foam or fabric layer. This layer may be bonded, ultrasonically welded, or held in place by an ultrasonically welded frame.The pins 313, the applicator 208 (without layer 315) and the housing 312 are made in one piece by injection molding in PE (Polyethylene) or PP (Polypropylene).

[0311] With reference to [Fig. 3b], the applicator 208 of the cap 310 forms a nozzle 309 arranged to precisely dispense the product. The tip of the nozzle carries a pad 316, which can be made of foam or fibers, for dispensing, for example, a lip gloss or lipstick. The outlet 24 is at the end of a rod in the pad 316. Several small holes can be made in this rod to homogenize the distribution of the product on the pad. In a version without a pad 316, the outlet 24 is located at the end of the nozzle 309. The dispensing piece does not pass through the stopper. The stopper 310 further includes a stopper 77 to plug the outlet 24; this stopper 77 is removable by means of a flexible link connected to the base of the nozzle 309. The pins 313, the applicator 208 (without the pad), the housing 312, the stopper 77, and the flexible link are made in one piece by injection molding from PE (Polyethylene) or PP (Polypropylene).

[0312] The device according to the invention may include an air pocket, and this air pocket may include an extraction hole 11 arranged to extract air from this pocket. This extraction hole is located at a distance of less than 3 cm from at least one of the filling holes, so that the fluid to be dispensed does not escape through the filling hole when the device is placed under vacuum.

[0313] The wall 22 is provided with a skirt 155 having a minimum height at least as high, in the same direction of measurement, as the height at the entrance of the housing 8 on the side of the pocket 2 (i.e. minimum of 2 or 3 mm).

[0314] This skirt 155 allows the valve 5 to be inserted into the housing 8 from inside the bag 2 perpendicular or substantially perpendicular to the direction of measurement of the height of this skirt 155.

[0315] The nozzle 89 is inserted into the plug 310. The distribution surface 207 is formed by the plug 310 and the nozzle 89.

[0316] Housing 312 includes plug 310 between pins 313.

[0317] Figures 3c and 3d describe another variant of device 101 which will not be described than for its differences compared to the variant in figures 2 and 3.

[0318] In this variant, the tip 89 comprises three parts: - An external crown - A central part (also forming part of the distribution unit 23) which carries the outlet 24, - At least one (preferably at least two, typically three) connecting walls 9 linking the outer ring of the tip 89 to the central part of the tip 89,

[0319] these connecting walls 9 being arranged to leave at least one empty space 15 between the outer ring of the nozzle 89 and the central part of the nozzle 89, this at least one empty space 15 being arranged to allow passage of a filling tube 46 which, by passing through this at least one empty space 15, penetrates to the inside of the reservoir 6 (typically along the outside of the pouch 22).

[0320] It is thus noted that the pocket 22 does not have a form of revolutional symmetry around the longitudinal axis of the device 101 to allow the passage of the cane 46.

[0321] Thus, a method according to the invention typically comprises, while the cap 310 is removed from the rest of the device 101, filling the reservoir 6 by means of the tube filling 46 which passes through this at least one empty space 15 and penetrates to the inside of the reservoir 6 (typically along the outside of the pocket 22), and thus fills the reservoir 6 with a fluid from outside the device 101 passes through the tube 46 into the reservoir 6.

[0322] After this filling, the cap 310 can be reassembled on the neck 85. For this purpose, the neck 85 includes an external thread 16, which is advantageous compared to an internal thread which would push the nozzle 89 and the outlet 24 inside the device 101 and make the latter less compact.

[0323] The neck 85 is integral with (and in line with) the walls of the reservoir 6.

[0324] It is further noted that this space 15 allows the passage of the rod 46 for The filling of the tank 6 is also shown in [Fig.3].

[0325] Figures 4 to 33 illustrate a second embodiment of six devices 102, 103, 104, 105, 106, 107. Unless otherwise stated or more specifically indicated, only the differences with device 101 of [Fig.1] will be described.

[0326] Each embodiment of device 102, 104, 105, 106, 107 for distributing a fluid comprises:

[0327] - exit 24,

[0328] - the pocket 2 having an internal volume for containing a fluid, the internal volume of pocket 2 being delimited at least in part by the movable wall 22,

[0329] - the reservoir 6 arranged to contain the fluid and comprising two openings of which the upper opening 124 oriented towards the pocket 2 and a lower opening 87, said reservoir 6 being arranged to decrease its internal volume during the discharge of fluid from the reservoir,

[0330] - the distribution valve 5 which, in an open state, allows the passage of fluid from the pocket 2 towards exit 24, and, in a closed state, does not allow it.

[0331] - the supply valve 4 which, in an open state, allows the passage of the fluid contained in reservoir 6 towards pocket 2, and which, in a closed state, does not allow it.

[0332] The lower opening 87 is arranged to allow the passage of fluid, preferably the passage of a cannula (or filling tube) carrying the fluid, so as to fill at least part of the reservoir 6 with fluid at least up to the supply valve 4 so that the fluid is in contact with the supply valve 4 and preferably so as to also fill at least part of the internal volume of the bag 2 with fluid.

[0333] The supply valve is arranged to allow the cannula or tube to pass through, for example by bending.

[0334] With reference to [Fig. 4], the distribution part 23 (also called the distribution head 23) comprises: - a 70s headdress, and - optionally an insert 71.

[0335] It is noted that the deformable wall 22 is not mobile in the cap 70. There is no part of the mobile pocket function in the cap 70. The cap 70 is mounted superimposed on the flexible wall 22. The wall 22 is a bellows or the base of a dome with an upper edge 228 connected to the cap 70 by continuity of material or overmolding or bi-injection, and a lower edge 229 connected to the wall 118 of the reservoir 6 by continuity of material or overmolding or bi-injection.

[0336] The junctions and / or connection with the edges 229 and 228 are watertight.

[0337] The deformable wall 22 is mounted superimposed on the wall 118 of the tank 6.

[0338] The distribution piece (23) comprising a cap (70)

[0339] the bearing surface (25) forming part of the distribution piece (23)

[0340] the housing (8) being located inside the cap (70)

[0341] the cap (70) being mounted superimposed on the deformable wall (22).

[0342] The deformable wall (22) and the cap (70) are:

[0343] - grouped into a single piece of the same material without any discontinuity in material, Or,

[0344] - manufactured in one piece by overmolding or bi-injection.

[0345] The distribution valve 5 is in a housing located inside at least one part 70 (of the distribution piece 23) having continuity of material with the wall 22, this housing is lateral and is positioned between the pocket 22 and the outlet 24. The connection between the cap 70 and the insert is airtight so as to have a sealed pocket 38 of air or gas.

[0346] The reservoir 6 arranged to contain the fluid and comprising two openings, the upper opening 124 oriented towards the pocket 2 and a lower opening 87, said reservoir 6 being arranged to decrease its internal volume when fluid exits the reservoir when pressure is applied to the wall 25 once the device has been primed, this phase is hereafter referred to as the pumping operation.

[0347] The reservoir 6 includes a rigid wall 99 inside which a piston 86 slides.

[0348] The piston 86 is located between the reservoir 6 and a bottom wall 91. The piston 86 is inserted into the opening 87 after the reservoir 6 has been filled through the opening 87, forming a plug 310. The reservoir 6 has an elongated cylindrical shape.

[0349] The reservoir 6 includes a side wall 118 or container 118 between the bottom wall 91 and the pocket wall 21.

[0350] The side wall 118 is part of a component 10 arranged to:

[0351] -containing piston 86,

[0352] -hold pocket wall 21 in place by tightening,

[0353] -form the wall 22 by continuity of the same material or in two different materials by bi-injection at the level of the junction 229.

[0354] The deformable wall 22 and the wall 10 are:

[0355] - grouped into a single piece of the same material without any discontinuity in material, Or,

[0356] - manufactured in one piece by overmolding or bi-injection.

[0357] At least one hole 95 made in the piston 86 or between the piston and the wall 99 allows to expel air from reservoir 6 when a portion of piston 86 (specifically the upper portion) is inserted into the reservoir. Thus, piston 86 comprises two lips: a first upper lip 88 (oriented towards 124) is designed to enter the reservoir in a non-sealing manner, as it is equipped with at least one hole 95, and a second lower lip 28 (oriented towards the bottom 91) is designed to enter reservoir 6 in a seal. Note that piston 86 is a single piece and is not equipped with a valve.

[0358] In order to reduce the air, the piston preferably includes a domed wall 26. The dome shape 26 reduces the air between the piston and the product and forces the cream or product to be dispensed to the sides against the wall 99 when the piston is introduced into the reservoir.

[0359] As long as the lower lip 28 of the piston is not fitted into the internal walls 99 of the reservoir 6, the air contained in the reservoir can escape from the device.

[0360] At least one hole 95 is arranged to also allow passage of fluid between the reservoir 6 and a sealing zone 97 included between the piston 86 and the wall 99.

[0361] Typically there are several holes 95. The openings 95 may be slits around the upper lip 88.

[0362] With reference to FIGURES 5 to 10, the reservoir 6 is delimited at least in part by a movable piston 86 arranged to move so as to decrease the internal volume of the reservoir 6 when fluid is exiting the reservoir 6, this piston 86 being provided with the lower opening 87, the lower opening 87 being closed by a removable plug 310.

[0363] The removable plug 310 is screwed onto the piston 86.

[0364] The piston 86 is contained between the reservoir 6 and a bottom wall 91, said bottom wall 91 preferably being rigid being provided with means 93 for blocking the rotation of the piston 86 when the plug 310 is screwed onto the piston 86 when the piston 86 is in contact with the bottom wall 91.

[0365] The bottom wall 91 is provided with fixing means 45 to fit together preferably by snapping with the rigid wall 118 of the tank.

[0366] Different variants of this embodiment can be combined with each other: - in the variant illustrated in [Fig. 6] the means 93 typically include, for example, a slot into which part of the piston 86 is inserted, and / or - in the variant illustrated in [Fig.7] the means 93 typically include, for example, clipping means, and / or - The piston may have a curved shape (disk, ellipse, or other) or a polygon. In the variant illustrated in [Fig. 10], the piston 86, in a cross-sectional view perpendicular to a direction of movement of the piston 86 along a wall 99, has a polygonal shape comprising several sides connected by angles. The device further includes a force distribution piece 33 arranged to support the piston 86 against the wall 99 at several (preferably all) sides of the polygon but outside the angles of the polygon. In another variant, the distribution piece 33 may be replaced by a variable thickness of the walls of the piston 86.

[0367] Figures 11 and 12 illustrate an embodiment of a device 104 for distributing a fluid. Only its differences with the device 103 of Figures 5 to 10 will be described.

[0368] With reference to figures 11 to 12, the piston 86 is not drilled and does not include a filling opening, the filling opening 87 is formed by the lower edge of the walls 118 (more precisely the opening 87 is cylindrical).

[0369] After the reservoir is filled, the piston 86 is placed in it, more precisely it is placed by sliding into the cylinder 87, 118 preferably during this step the bottom wall 91 is fixed on the piston.

[0370] The lower lip 28 is attached to the bottom wall 91 by elastic means 32 at least before insertion into the opening 87.

[0371] When introduced into the opening 87, the lip 28, equipped with the elastic means 32, deforms, causing the elastic means 32 to move towards the axis of the piston. This movement separates the elastic means 32 from the bottom wall 91. To accentuate this deformation, it is advantageous to add a local excess of material to the internal walls 99 of the reservoir 6, such as a ring of material 29. The elastic means 32 are arranged to easily detach from the bottom 91 during the first pumping operations (before the first 10 pumping operations), that is, upon compression of the wall 22 once the device is primed.

[0372] Projecting walls 31 of the bottom 91 are arranged to hook with the elastic means 32 and raise the piston 86 relative to the bottom wall 91. At least a part of the projecting walls 31 are inserted between the elastic means 32 and the lip 28. The elastic means 32 can be clipped onto the projecting wall 31.

[0373] FIGURES 12a and 12b illustrate part of the second embodiment of the device 104 according to the invention in a variant with a modified piston 86; this variant will only be described for its differences from the description in Figures 11 and 12.

[0374] The cap 86 includes lips.

[0375] The upper part 88 of these lips (or "upper lips") is the first to enter the reservoir 6 when the piston 86 is inserted through the opening 87.

[0376] The lower part 96 of these lips (or "lower lips") is the second (or last) to enter the reservoir 6 when the piston 86 is inserted through the opening 87.

[0377] The upper lips 88 are provided with reliefs or ribs or studs 197 which separate the upper lips 88 from the internal walls 118 in order to allow air or product to be distributed to escape from the reservoir 6 through the opening 87 by passing between reliefs or ribs or studs 97 when the piston 86 is inserted through the opening 87.

[0378] The lower lips 96 are arranged to ensure a seal of the opening 87 between the inside of the reservoir 6 and the outside of the device once these lower lips 96 are penetrated between the walls 118 by the opening 87.

[0379] Lateral openings 94 inside the piston 86 allow air to escape and prevent an air bubble from forming in the piston 86 when the piston 86 is inserted through the opening 87

[0380] The piston 86 includes means 98 for retaining the piston 86 to the wall 91. There is no external wall of part 91 surrounding the outside of the piston, even partially. To improve the retention of the piston, a wall of part 91 (not shown) can be fitted inside the piston 86. These retaining means 98 typically include:

[0381] - a rod or other means, integral with the piston 86, and which fits or clips or fixed to wall 91, or

[0382] - reception means into which a rod or another means, attached to wall 91

[0383] the piston 26 and the wall 91 being joined when the piston 86 is inserted into the opening 87, the piston 26 and the wall 91 being arranged to separate when the piston 86 progresses between the walls 118 in the reservoir 6 (the wall 91 itself remaining fixed) and / or by a mechanical action when the device is closed.

[0384] Figures 13 to 22 illustrate another embodiment of a device 105 for distributing a fluid. Only its differences with the device 104 of Figures 11 to 12 will be described.

[0385] The wall 108 is flexible or consists mainly of flexible walls (hereinafter referred to as "flexible wall 108" or "wall 108").

[0386] The reservoir 6 arranged to contain the fluid is delimited by:

[0387] - a flexible partition 108 comprising two openings, the upper opening 124 oriented towards pocket 2 and the lower opening 87, and

[0388] - a bottom wall 91, 310 preferably removable, arranged to block the lower opening 87.

[0389] The plug 310 is integrated into the wall 91.

[0390] The flexible wall can, for example, be injected or thermoformed.

[0391] The area of ​​a section of the upper opening 124 (this section being chosen for minimizing the area of ​​the upper opening 124) is at least six times (and even at least eight times) smaller than the area of ​​a section of the lower opening 87 (this section being chosen to minimize the area of ​​the lower opening 87).

[0392] The flexible wall 108 is arranged to deform in such a way as to decrease the internal volume of the reservoir 6 when fluid exits the reservoir 6.

[0393] The rim 43 and / or the skirt 42 is arranged to provide a seal between the inside of the tank and the outside of the device.

[0394] The device 105, more precisely the rigid wall 91, is arranged to maintain fixed the position of the lower opening 87 in the device 105 relative to the position of the upper opening 124 in the device 105.

[0395] The flexible wall 108 is fixed to the pocket 2 by means of a watertight joint.

[0396] The flexible wall 108 includes a cylinder 81 above the reservoir 6 allowing Sealing. To achieve a seal, this cylinder 81 is either compressed (as in Figures 14 and 16) or fitted together (as in [Fig. 13]). It is preferable to have a second cylinder concentric with the first cylinder 81.

[0397] The device 105 includes (optional) internal guidance means 110 for the cap 70 (which is the component forming the internal volume of the pouch 2 and also containing the distribution valve 5). The means 110 are arranged to guide movement of the cap. The means 110 take the form of a wall 110 emerging from the bottom wall 21.

[0398] Different variants of this embodiment 105 can be combined with each other: - the flexible wall 108 is attached to the pocket 2 via a watertight joint: • by welding, and / or • by clipping (using clip 83), and / or by interlocking, as illustrated in the variant in Figure 13 and / or • by compression of the flexible wall 108 around its upper opening 124 between, on the one hand, a part forming or integral with the pouch 2 and located outside the reservoir 6 and, on the other hand, a ring 109 (and whose upper edge forms the feed seat 62 as previously described) inserted inside the reservoir 6, as illustrated in the variants of Figures 14 and 16, 18. In the variant of Figure 14, the ring 109 is integral with the rigid wall 91 and the ring 109 and the wall 91 form a single piece with continuity of material, whereas in the variant of Figures 16 and 18 the ring 109 and the wall 91 form two separate pieces without continuity of material; and / or - the flexible wall 108 and the supply valve 4 are formed in the same piece with continuity of material (as illustrated in figures 16 to 18) or in two separate pieces without continuity of material (as illustrated in figures 13 to 15).

[0399] With reference to Figures 19 to 22, the device 105 is "flat". To reduce trapped air during closure, a retaining element 17 holds the tank walls in place on the sides, but does not provide a seal. The seal is achieved by axial compression rather than lateral compression. If the tank is injection-molded from a flexible material, no additional seal is required, but if the tank is thermoformed, it is preferable to add a seal 39 if the precision of the injection-molded parts 93 and 122 is insufficient. The seal 39 includes at least one flexible face in contact with the wall 108 to ensure a seal between the tank 6 and the outside.

[0400] In the case of a flexible wall 108 obtained by thermoforming in order to refine its thickness typically around 0.2 mm, it is proposed to deform the raw material (typically a sheet or a film) to a thickness deeper than the thickness of the reservoir thus forming a "thick piece" (for example a deformation 1.5 or 2 times deeper) then a partial cutting of this "thick piece" to extract the pocket 108.

[0401] It is noted that the bottom wall 21 includes a ring 48 at the opening 124, this ring is deformed (in a direction opposite to the center of the hole 41) preferably by ultrasound and is arranged to compress the wall 108 of the reservoir.

[0402] Figures 23 to 29 illustrate another embodiment of a device 106 for distributing a fluid according to the second aspect. Only its differences with the device 105 of Figures 13 to 22 will be described.

[0403] With reference to [Fig.23], the wall 91 is screwed onto a neck 87 of the reservoir 6.

[0404] The lower opening 87 takes the form of a neck referenced 85 or 87.

[0405] This neck 87 of the reservoir 6 forms an inlet orifice for filling the reservoir 6 when this neck is not screwed to the wall 91.

[0406] The wall 91 therefore forms a plug for this neck 87. The wall 91 integrates in a single piece preferably in the same material the plug 310 arranged to screw onto the neck 87 and fixing means 45 arranged to fit with the wall 12, preferably by snap-fit.

[0407] The wall 91 is connected to side walls 12 arranged so that, when this neck is screwed to the wall 91: - hide tank 6, and - maintain the tank 6.

[0408] The wall 12 surrounds a wall 108 delimiting an internal volume of the tank 6 (delimiting at least 50% and even at least 75% of the internal volume of the tank 6).

[0409] These side walls 12 are fitted or snapped into place with the wall 91. The wall 91 includes snap-in means 45.

[0410] The tank is blow-molded in PE (Polyethylene) or PP (Polypropylene).

[0411] The tank 6 includes a hump 60 arranged to be welded to the bottom wall 21.

[0412] The wall 12 and the wall 21 form a container 122 arranged to contain the reservoir 6.

[0413] The side wall 12 is part of a part 100 or wall 100 arranged to:

[0414] -contain the flexible walls 108,

[0415] -hold the pocket wall 21 in place by tightening

[0416] -form the wall 22 by continuity of the same material or in two different materials by bi-injection at the level of the junction 229.

[0417] The deformable wall 22 and the wall 100 are:

[0418] - grouped into a single piece of the same material without any discontinuity in material, Or,

[0419] - manufactured in one piece by overmolding or bi-injection.

[0420] The wall 91 includes screwing means 310 for closing or sealing the reservoir 6 in a leak-proof manner. During the screwing operation, the reservoir can be lifted (translated towards the wall 91) and / or deformed by extending towards the bottom wall 91. Only the bottom wall 91 is rotated by an external tool (not shown) in order to close the neck of the reservoir 6.

[0421] Once the screwing operation is completed, an axial force on the wall 91 towards the reservoir allows the wall 91 to be fixed with the wall 12.

[0422] The wall 91 includes means for fixing 45 to the container 122. The fixing means may preferably include a fitting, and more preferably a snap-fit ​​fitting of the wall 91 with the container 122, more specifically with the wall 12.

[0423] The wall 91 allows the container 122 to be closed or sealed, preferably in a non-airtight manner.

[0424] The deformable wall 22 and the wall 12 of the container 122 are:

[0425] - grouped into a single piece of the same material without any discontinuity in material, Or,

[0426] - manufactured in one piece by overmolding or bi-injection.

[0427] With reference to Figures 24 to 29, device 106 of Figures 24 to 29 is distinguished by the following elements.

[0428] The flexible wall 108 of the reservoir 6 is itself enclosed in a wall 12 of a container 122.

[0429] First, it includes an anti-rotation system for tank 6: - In the case of the embodiment common to Figures 24 to 28, this anti-rotation system takes the form of: • At least one relief 40 on the wall 108 of reservoir 6, preferably several reliefs 40 (typically respectively hollows or bumps) • At least one relief, preferably several reliefs (typically respectively bumps or hollows) on the wall 12 and / or 21 and / or 91 arranged to block the rotation of the reliefs of the wall 108 and thus block the rotation of the reservoir 6 (preferably, the relief of the wall 12 includes at least one fin 19 which extends along the elongation axis of the container 122), - in the case of the embodiment of [Fig.29], this anti-rotation system includes the square or polygonal or more generally non-cylindrical shape of the wall 108, and the square or polygonal or more generally non-cylindrical shape of the wall 12.

[0430] The walls 108 and the reliefs 40 are preferably produced by injection blow molding or extrusion blow molding. It should be noted that the relief(s) 40 are produced on a lateral wall of the tank 108 (relative to the axis of elongation of the tank).

[0431] The neck 87 and the hump 60 are more rigid than the side walls of the tank 6.

[0432] The flexible side walls of the tank 6 are typically on the order of 0.15 to 0.4 mm thick to optimize emptying. These thin walls pose a rigidity problem when closing the tank. Unlike the device in [Fig. 23], this anti-rotation device prevents excessive twisting of the tank (typically less than 20 degrees).

[0433] The wall 91 and the plug 310 are two separate parts.

[0434] Rails 90 allow the plug 310 to slide with the bottom wall 91. These rails allow the plug 310 to rotate when the wall 91 is turned. This sliding mechanism prevents the reservoir from lifting during screwing; the cap 310 can translate even if the bottom wall 91 comes into contact with the end of the side wall 12 before insertion, particularly at the insertion or snap-fit ​​means 45. The cap is arranged to slide with the bottom wall 21 at least at the end of screwing.

[0435] The plug 310 is held in the part 91 (for example by clipping means with a clearance allowing axial sliding) and can slide in the part 91.

[0436] The stopper is held with the wall 91 at the beginning of the pumping operations but can detach from the bottom 91 after a certain number of pumping operations.

[0437] The walls 108 of the tank 6 include a neck 85.

[0438] The neck 85 of the walls 108 of the tank 6 includes threads arranged to cooperate with cap 310.

[0439] The walls 108 are pierced opposite the neck 85 so as to form the opening 124 fixed on the bottom wall 21.

[0440] The cap 310 includes a hollow 311 so as to reduce the air in the reservoir 6 after closure.

[0441] The container 122 is closed by pressing on the part 91 after the screwing phase of the cap 310 with the neck 85.

[0442] A rib or fin 19 in the container 122 is arranged to block the walls 108 of the reservoir 6.

[0443] With reference to [Fig.25], initially the bag wall 21 is assembled with the flexible wall 108. Then, optionally, the valve 4 is inserted, the at least assembly 21 and 108 is inserted into the container 122 up to the foot of the wall 22, the assembly being held by tightening the part 100 with a lateral part of the bag wall 21.

[0444] It is noted that the elements 91 and / or 310, connected to the neck 85, is an intermediate piece between the walls 12 and 108. The piece 91 and / or 310 is located at one of the ends of the device 106. Apart from the intermediate piece(s) 91, 310 connected to the neck 85, there is no other intermediate piece connecting the walls 12 and 108 over at least one half (or even at least two-thirds) of the elongation of the walls 12, 108 from the neck 85 but outside the neck 85.

[0445] It is further noted that this or these intermediate parts 91 and / or 310 are connected to the walls 12, 108 without gluing, welding or co-extrusion, which is advantageous for the recycling of the device.

[0446] This or these intermediate pieces 91 and / or 310 are therefore removable (by screwing, unscrewing) from the walls 12, 108.

[0447] The distribution valve 5 is located inside the rigid part 70 carried by the movable wall 22 so that this rigid part 70 is arranged to translate by deformation of the movable wall 22.

[0448] The wall 22 is in continuity of material or overmolding or bi-injection with the part 70.

[0449] Figures 30 to 33 illustrate another embodiment of a device 107 for distributing a fluid according to the invention. Only its differences with device 106 will be described.

[0450] With reference to Figures 30 to 33, the neck 85 has no screw thread. Means 84 hold the reservoir 6 during the insertion of the cap 310.

[0451] The means 84 are a border or a hollow at the level of the neck 85.

[0452] A tool 82 holds the means 84 (attached to the neck 85) immobile during the insertion of the cap 310.

[0453] In the embodiment of figures 32 and 33, the reservoir can be compressed, which allows for a lower junction height between parts 12 and 91.

[0454] Conversely, in the embodiment of Figures 30 and 31, the junction height between parts 12 and 91 must be higher because the reservoir is not compressible, but the height of part 91 must allow the use of tool 82.

[0455] Figures 34 and 35 illustrate another embodiment of a device 1060 for distributing a fluid according to the invention. Only its differences with device 106 will be described.

[0456] With reference to Figures 34 to 35, in this embodiment, the anti-rotation system of the reservoir 6 comprises: - as illustrated in figures 34 and 35 • one or more reliefs 40 (typically respectively hollows or bumps) on the wall 108 of the reservoir 6 • one or more reliefs (typically respectively bumps or hollows) on the wall 12 and / or 21 arranged to block the rotation of the reliefs of the wall 108 and therefore block the rotation of the reservoir 6, (preferably these reliefs are arranged on the wall 12 and include at least one fin 19 which extends along the elongation axis of the device), - in an unillustrated variant, it includes the square or polygonal or more generally non-cylindrical shape of wall 108, and the square or polygonal or more generally non-cylindrical shape of wall 12.

[0457] Unlike previous embodiments in which the openings 87, 124 were separate and located on either side of the reservoir 6 at two different (preferably opposite) locations on the reservoir 6, device 1060 includes openings 87 and 124 that are combined at the same level. The bottom wall 21 acts as The rigid wall 91 is equipped with screwing means 310. These screwing means 310 can be arranged to slide (more precisely the wall 44) in the bottom wall 21 in a sealed manner, this prevents the reservoir 6 from lifting when the bottom wall 21 is screwed on. Once the screwing operation is complete (the cap skirt providing a seal), an axial force towards the reservoir at the foot of the deformable wall 22 allows the head of the device 1060 (more particularly the distribution head) to be snapped into place by means of the snapping means 47.

[0458] Figures 36 and 37 illustrate a fourth embodiment of a device 4000 according to the invention for distributing a fluid according to the invention. Only its differences with device 102 of [Fig. 4] will be described.

[0459] With reference to Figures 36 to 37, in this embodiment, pocket 2 is delimited:

[0460] - partly by the deformable wall 22, and

[0461] - partly by rigid walls of a distribution head 400 fixed to the wall deformable 22 of the pocket 2 so that the distribution head 400 is supported by the deformable wall 22 in various possible positions relative to the reservoir 6, of which at least:

[0462] * a stable position (as illustrated in [Fig. 36]) in the absence of force external force exerted on the head 400 and

[0463] * an inclined position at an angle of inclination relative to the stable position When an external force is applied to the head 400, the deformable wall 22 is deformed, thereby decreasing the internal volume of the pocket 2 compared to its stable position. This external force is typically applied to the head 400 by the face and / or cheek and / or lips and / or the contour of an eye of a user.

[0464] The head comprises a distribution surface 7 which borders or surrounds the outlet 24, preferably with a surface area of ​​at least 50 mm² and even at least 70 mm². The distribution piece 23 comprises the distribution surface 7 and is fitted or screwed to one end of the hollow member 406, the other end of the hollow member 406 being connected to the wall 22 by continuity of material, overmolding, or bi-injection. This distribution surface 7 is arranged for massage and for exerting the tilting force on the device.

[0465] The inlet valve 4 is of the "duck valve" type, particularly tight-fitting and allowing the introduction of a needle through the valve 4. In the present description, the "duck valve" may be single-slit or cross-slit.

[0466] Valve 4 can be made by overmolding on the bottom wall 21.

[0467] The bottom wall 21 forms a plug or insert in the pocket 2.

[0468] A degassing element 411 is arranged to allow gas to pass from the bag 2 to the reservoir 6 when the bag 2 is filled with a liquid and / or gel by means of a needle passing through the valve 4 (or filling valve) inserted on the side of the reservoir 6 whose cap 91 is open and the piston 86 is absent during this filling.

[0469] This element 411 typically includes a valve or a gap or space between the wall 21 and the pouch 2 or a slot in the bottom wall 21. The pouch 2 includes degassing means 411 at the bottom wall 21; the degassing means 411 are on the side of the reservoir 6, oriented towards the reservoir 6. With reference to [Fig. 37], in this embodiment, the valve 411 is wedged between the bottom wall 21 and the head 400 at the foot of the pouch 2 or between the bottom wall 21 and the wall 118. In a version not shown, the valve 4 is wedged between the bottom wall 21 and the head 400 at the foot of the pouch 2 or between the bottom wall 21 and the wall 118.

[0470] Wall 22 is connected and fixed to wall 118.

[0471] The wall 22 is in continuity of material or overmolded or bi-injection with the wall 118 of the reservoir 6 (as illustrated in [Fig.36]) and / or with the wall 12 surrounding the wall 118.

[0472] The wall 118 of the tank 6 delimits the internal volume of the tank 6 (delimiting at least 50% and even at least 75% of the internal volume of the tank 6). The wall 12 surrounding a wall 118 delimiting an internal volume of the tank 6 (delimiting at least 50% and even at least 75% of the internal volume of the tank 6).

[0473] The rigid wall of the head 400 has its inclination limited by a passage hole 412 and / or by the wall 21 at several contact points 401 (with the hole 412), 404 (with the hole 412), 402 (with the hole 412), 403 (with the wall 21). The head 400 optionally includes, in addition to part 23, a massage element 408 with two lateral massage faces relative to the product outlet; the contact points are arranged to prevent inclination during massage.

[0474] The distribution valve 5 is located inside the rigid part 400 carried by the movable wall 22 so that this rigid part 400 is arranged to tilt and / or translate by deformation of the movable wall 22.

[0475] The wall 22 is in continuity of material or overmolding or bi-injection with the part 400. It is noted that the elongation axis of the head 400 is substantially the same as the elongation axis of the reservoir 6.

[0476] Figures 38 and 39 illustrate a fifth embodiment of a device 5000 according to the invention for distributing a fluid according to the invention. The cover 222 comprises the wall 22 and the distribution surface 7. The pocket 2 is formed by the cover 222 and the bottom wall 21 extending in the same direction to to form a "flat" pocket. Subsequently, only its differences with device 105 of [Fig. 19] will be described.

[0477] In this embodiment, the valve 4 (more precisely one end) is trapped or wedged between the bottom wall 21 and the periphery or foot of the wall 22, in particular between the bottom wall 21 and the cover 222.

[0478] A degassing element 411 is arranged to allow gas to pass from the bag 2 to the reservoir 6 when the bag 2 is filled with a liquid and / or gel by means of a needle passing through the valve 4 inserted on the side of the reservoir 6, the cap 91 of which is open during this filling. As illustrated in [Fig. 38], there may be several supply valves 4 and 4b used for filling, associated with several degassing elements 411 and 411b.

[0479] A degassing channel 211 connects the element 411 to the feed port 41.

[0480] This element 411 typically includes a valve or a gap or space between the wall 21 and the pocket 2 or a slot in the bottom wall.

[0481] The degassing means 411, 211 are preferably oriented towards the reservoir 6. It is preferable that the valve used for filling the bag 2 be arranged so that its seat in the bottom wall 21 is at a lower level towards the reservoir 6, therefore preferably like valve 4b, however at the same time it is preferable that the supply valve 4 be as close as possible to the deformable wall 22. In another variant not shown, the distribution valve 5 is further from the reservoir 6 than the supply valve 4.

[0482] Figures 40 to 44 illustrate a sixth embodiment of a device 6000 according to the invention for distributing a fluid according to the invention. Only its differences with device 105 of [Fig. 13] will be described.

[0483] With reference to Figures 40 to 44, in this embodiment, each internal guide means 110 (typically in the form of a wall) of the cap 70 is coupled to at least one rail 112 and / or a slide 113, the rails 112 and / or a slide 113 being arranged to guide the cap 70 on the means 110. [Fig. 41] shows walls 110 surrounding rails 112 of the cap 70. In an illustrated variant [Fig. 42], walls 110 cooperate with slides 113 of the cap 70, this slide being formed by rails 112.

[0484] Each rail 112 and / or slide 113 is integral with the cap 70.

[0485] This rail / slide assembly can be replaced or supplemented by another rod / cylinder assembly arranged so as not to compress the product. Preferably, at least one rail / slide assembly is arranged to provide transverse support in all directions, as illustrated in [Fig. 42], which includes a dovetail-type slide.

[0486] The inlet valve 4 is of the "duck valve" type, particularly airtight and allowing the introduction of a needle through the valve 4.

[0487] The distribution valve 5 includes a nipple 90 (or a stem 90) integral with a movable member of the valve 5.

[0488] Nipple 90 is:

[0489] - partially (in particular not the tip of nipple 90) included within the deformable chamber 2 in the closed position of the distribution valve 5, and / or

[0490] -entirely contained within the deformable chamber 2 in the open position of the distribution valve 5.

[0491] The movable member of the valve 5 is entirely contained within the deformable chamber 2.

[0492] The distribution valve 5 is:

[0493] - partially (in particular not the tip of nipple 90) included within the deformable chamber 2 in the closed position of the distribution valve 5, and / or

[0494] - entirely contained within the deformable chamber 2 in the position open distribution valve 5.

[0495] Nipple 90 has an end which: - in the closed state of the distribution valve 5, it blocks the outlet 24 of chamber 2 and - in the open state of the distribution valve 5 is separated from the outlet 24 of chamber 2 relative to the closed state of the distribution valve 5.

[0496] The movable member of the valve 5 is arranged to move under the effect of an overpressure of the fluid in the internal volume of the chamber 2, exceeding a pressure threshold (depending in particular on the total stiffness of the return means 696) relative to the equilibrium state of the chamber 2, so as to move the nipple 90 away from the outlet 24 of the chamber 2, thereby moving the distribution valve 5 from its closed state to its open state. Such an overpressure can be caused by a decrease in the internal volume of the chamber 2 filled with the fluid to be distributed, for example when a user presses on the support surface 25.

[0497] The movable member of the valve 5 is further arranged, in other cases, to keep the valve 5 closed or to move so as to move the nipple 90 towards the outlet 24 of the chamber 2 so as to move the distribution valve 5 from its open state to its closed state.

[0498] The movable member of the valve 5 comprises at least one movable wall 91 of at least one gas pocket 92.

[0499] Each movable wall 91 is entirely contained within the deformable chamber 2.

[0500] At least one gas pocket 92 contains a gas (typically air), preferably without the possibility of it escaping from that pocket 92. At least one gas pocket 92 is arranged to isolate this gas (represented by small dots in the figures) from the fluid contained in the deformable chamber 2.

[0501] The gas pocket 92 is completely surrounded (along a closed loop surrounding this pocket 92 at 360° around this pocket 92) by the fluid contained in chamber 2.

[0502] The movable wall 91 of each gas pocket 92 has a contact surface 697 arranged to be entirely in contact with the fluid contained in the chamber 2.

[0503] This contact surface 697 of the pocket 92 is defined as the surface of the wall 691 (typically less than 1mm thick or preferably less than 500pm) which is arranged on one side to be in contact with the fluid contained in the chamber 2 and on the other side opposite to the first in contact with the gas of this pocket 92; the surface of the nipple 90 is therefore not counted.

[0504] The sum of the areas of the contact surfaces 697 of the gas pocket(s) 92 is at least 50mm2 and even greater than 70 mm2 and even greater than 90 mm2.

[0505] The device 6000 includes a movable wall 691 of a gas pocket 92 aligned along an elongation axis of the nipple 90, this elongation axis also being a displacement axis of the nipple 90 between the open position and the closed position of the valve 5.

[0506] The pressure inside each pocket of gas 92 is typically:

[0507] - greater than one atmosphere and / or

[0508] - within the range between 0.9 and 1.5 atmospheres, preferably in the interval between 0.9 and 1.1 atmospheres, preferably equal to one atmosphere

[0509] The distribution valve 5 and at least one gas pocket 92 are part of a module 693 inserted into the device 6000 from outside the device 6000. The module 693 is fitted into the rest of the device 6000, more precisely to the cap 70.

[0510] Module 693 fitted into the rest of device 6000 in a sealed manner.

[0511] Module 693 includes a tank or tube 602 comprising two diameters: - A smaller diameter portion to receive nipple 90, - A larger diameter section designed to fit into the 70 cap.

[0512] The module 693 includes a cover 603 fixed (typically welded or fitted) to the tank or tube 602 and delimiting the interior of the pouch 92 with the wall 691.

[0513] The nipple 90 and / or the movable member of the valve 5 are arranged to be in contact with the fluid contained in the deformable chamber 2.

[0514] The nipple 90 is arranged only to be partially in contact with this fluid contained in chamber 2: indeed, in the closed position of the valve 5, the end of the nipple 90 is hidden from the inside of chamber 2 by the outlet 24.

[0515] The movable member of the valve 5 is arranged only to be partially in contact with this fluid contained in the chamber 2: indeed, the movable wall 691 has a wall internal in contact with the gas of its pocket 92. The movable wall 691 is a succession of bellows forming a screw thread.

[0516] The device 6000 includes at least one return means 696 arranged to exert a return force on the nipple 90 so as to push the nipple 90 towards the outlet 24 of the chamber 2 so as to return the distribution valve 5 from its open position to its closed position.

[0517] The at least one retrieval means 696 comprises a movable wall 691 in the shape of a bellows

[0518] The movable wall 691 is arranged to deform during its movement.

[0519] Each gas pocket 92 makes it easier for a user to move valve 5 from its closed state to its open state, while ensuring proper closure of valve 5 in its closed state.

[0520] The internal volume of the deformable chamber 2 is delimited at least in part by the cap 70.

[0521] The internal volume of the deformable chamber 2 is delimited at least in part by the bottom wall 21 forming a plug inserted into the pocket 2.

[0522] The distribution seat is formed by the set of contact points, of module 693, between the distribution valve 5 and module 693 when the valve 5 is in its closed state.

[0523] It is noted that there is no valve on the fluid circulation path between the inlet 41 (and / or valve 4) and the distribution valve 5.

[0524] It is noted that there is no mechanical link between the cap 70 and at least one pocket 92, the only link between the wall 25 and at least one pocket 92 being made via the fluid to be distributed.

[0525] With reference to Figures 43 and 44, outlet 24 is delimited by a perimeter comprising:

[0526] - a so-called flexible part 694 (for example in TPO)

[0527] - a so-called rigid part 695 (for example, made of Polypropylene) in a more rigid or hard than the soft part 694 (the two hardnesses compared being measured in the same unit among Shore A or Shore D), the rigid part 695 being closer to the outside of the deformable chamber 2 than the soft part 694.

[0528] Part 694 is a flexible independent part mounted with a clamp between the internal walls of the tank or tube 602.

[0529] The nipple 90 is more rigid or harder than the soft part and the rigid part (the hardnesses compared being measured in the same unit among Shore A or Shore D).

[0530] For nipple 90:

[0531] -the nipple hardness is greater than 30 Shore D, or even greater than 70 Shore D, and / or

[0532] - the nipple 90 has a flexural modulus greater than 200 MPa, or even greater than 500 MPA.

[0533] The nipple 90 is flush (as illustrated) or protrudes less than 1 mm from outlet 24.

[0534] The end of the nipple 90 is less than 1 mm from the outlet 24 (in front of or behind the outlet 24).

[0535] In the closed position of the distribution valve 5 illustrated in [Fig.44], the end of the nipple 90 is in contact with the flexible part 694 along a first line of contact, preferably along an edge 651 of the nipple 90. This first line of contact is a closed line of contact going around the nipple 90.

[0536] The edge 651, in view of cutting nipple 90, forms an angle of less than 150° or even 90 degrees on the side of nipple 90.

[0537] In the closed position of the distribution valve 5 illustrated in [Fig. 11], the end of the nipple 90 is further in contact with the rigid part 695 along a second line of contact, preferably along an edge 652 of the nipple 90. This second line of contact is a closed contact line going around the nipple 90.

[0538] The edge 652, in view of cutting the cap 70, forms an angle less than 150° on the side of the tank 602.

[0539] It is noted on part 694 that the face just behind the contact line 651 is not in contact with a rigid part 695, there is a space 699 between parts 695 and 694, this allows additional flexibility to more easily obtain the two contact lines 651 and 652.

[0540] The nipple 90 is arranged so that, when the valve 5 passes from its open position to its closed position, the first contact line is formed before the second contact line.

[0541] The maximum distance between the first contact line and the outside of chamber 2 on the outlet side 24 is less than 6mm or even 4mm.

[0542] With reference to figures 40, 41 and 42, it is noted that the device 6000 includes a hole 65.

[0543] More precisely, this hole 65 is located on a side wall of module 693.

[0544] Hole 65 allows air to escape from module 693 when the reservoir 3 and / or pouch 2 and / or valve 5 with product to be dispensed, for example by a filling tube passing through opening 87 then through opening 4L

[0545] Preferably, the opening 87, the opening 41 and the opening 65 are aligned in that order, i.e. a straight line can pass through these three openings in that order.

[0546] Figures 45 and 46 illustrate an embodiment of a device 7000 for distributing a fluid. Only its differences with the device 6000 of Figures 40 to 44 will be described.

[0547] In this embodiment, at least one recall means 696 comprises a movable convex and flexible wall 691 forming a dome.

[0548] With reference to figures 45 to 46, in embodiment 7000, the valve 5 and the outlet 24 are located along or at the end of a rod 160.

[0549] This rod 160 opens from the surface 22 and / or 25, and therefore connects the surface 22 and / or 25 located at one end of the rod 160 to the valve 5 and the outlet 24 located at the other end of the rod 160.

[0550] This rod 160 includes a channel which connects the pocket 2 to the outlet 24.

[0551] The length 161 of the rod 160 between the surface 25 on one side and the outlet 24 is at least 25 mm, preferably at least 35 mm or even at least 45 mm

[0552] The inlet valve 4 is of the "duck valve" type, particularly airtight and allowing the introduction of a needle through the valve 4.

[0553] Valve 4 can be made by overmolding on the bottom wall 21.

[0554] The feed valve 4 is provided with protective means 204 arranged to protect the valve 4 when a syringe is inserted through the feed port 4L. These means 204 take the form of a cone or a ring that fits into the base of the valve 4 (on the reservoir 6 side). This cone or ring 204 is either part of the bottom wall 21 or a separate piece attached to the bottom wall 21 (but which is preferably fixed to the bottom wall 21).

[0555] The wall 691 is inserted into the wall of an applicator 208 where the outlet 24 opens.

[0556] This applicator 208 allows the product to be spread, a part of the body (for example a face and / or a cheek and / or lips and / or an eye contour) to be massaged with the product to be distributed, etc.

[0557] The wall of the applicator is composed of a superposition of two layers, preferably: - On the side of wall 691 and / or valve 5, a layer of plastic material, for example PP or PE - On the outlet side, a metallic layer, for example stainless steel, or a layer of foam, or even a layer of fabric.

[0558] The applicator 208 has a distribution surface which borders or surrounds the outlet 24 preferably with a surface of at least 50mm2 and even of at least 100mm2.

[0559] Figures 47 and 48 illustrate an embodiment of a device 8000 for distributing a fluid. Only its differences with the device 7000 of Figures 45 to 46 will be described.

[0560] In this embodiment, the rod 160 emerges from the surface 22, and thus connects the surface 22 located at one end of the rod 160 to the valve 5 and the outlet 24 located at the other end of the rod 160. The length 161 of the rod 160 enters on one side the surface 22 and outlet 24 is at least 25 mm preferably at least 35 mm or even at least 45 mm.

[0561] Due to the flexibility or ability of the wall 22 to deform, the rod 160 is arranged to tilt.

[0562] In this embodiment, pocket 2 is delimited:

[0563] - partly by the deformable wall 22, and

[0564] - partly by rigid internal walls of the rod 160 fixed to the deformable wall 22 of pocket 2 so that the rod 160 (which therefore forms a distribution head 400 as described with reference to Figures 36 and 37) is supported by the deformable wall 22 in various possible positions relative to the reservoir 6, of which at least:

[0565] * a stable position (as illustrated in [Fig. 47]) in the absence of force external force exerted on rod 160 and

[0566] * an inclined position at an angle of inclination relative to the stable position When an external force is applied to the rod 160, the deformable wall 22 is deformed, thereby decreasing the internal volume of the pocket 2 compared to its stable position. This external force is typically applied to the rod 160 by the face and / or cheek and / or lips and / or the contour of an eye of a user.

[0567] The means 204 take the form of a cone or a ring which is inserted at the base of the valve 4 (on the side of the reservoir 6). This cone or ring 204 is either a part of the bottom wall 21 (as illustrated in [Fig.48]) or an added part separate from the bottom wall 21 (but which is preferably fixed to the bottom wall 21).

[0568] The valve 4 is wedged between on one side the means 204 and / or the bottom wall 21 and on the other side a rigid extension attached to the wall 22.

[0569] The wall 691 and / or the valve is fixed between the massage element 408 and the outlet 24 and / or the applicator 208.

[0570] Figures 49 to 52 illustrate an embodiment of a device 9000 for distributing a fluid. Only its differences with the device 4000 of Figures 36 to 37 will be described.

[0571] The wall 12 and the wall 21 form a container 122, arranged to contain the reservoir 6 and the pouch 2.

[0572] The container includes a joint 175 between an upper part 170 of the container 122 and a lower part 180 of the container 122.

[0573] This joint 175 is:

[0574] - either an articulation by a flexible intermediate wall of the container 122 between the parts 170 and 180, as illustrated in [Fig.49],

[0575] - i.e. a rigid joint by interlocking the two parts 170 and 180.

[0576] This joint is arranged to allow the head to tilt 400.

[0577] The head 400 passes through a hole 173 made in the container 122, so that the head 400 includes at least one part 152 outside the container 122 and at least one part 202, 5, 22 inside the container 122.

[0578] Part 23 includes fastening means for attaching the head 400 to the container 122, for example: - As illustrated in [Fig.50] or 51, by clamping a part 171 (also called the fixing plate 171) of the container 122 between two parts of the assembled head 400, these two parts of the head 400 comprising a second part 152 (for example a rider or a ring) located at least partly outside the container 122 and at the end of the head 400 and fixed to a first part 151 (comprising for example a screw thread 201 and a stop 202) located at least partly inside the container 122. These two parts 151 and 152 can for example hold between them a free-rotating distribution ball 150 ([Fig.50]) onto which the outlet 24 opens or a distribution foam or pad 150 ([Fig.51]) onto which the outlet 24 opens. - As illustrated in [Fig. 52], by holding a part 171 (also called the fixing plate 171) of the container 122 by at least a part of the head 400, including a first part 151 (comprising, for example, a rider gripping the part 171) of the head 400 and at least partly located inside the container 122 (and partly outside the container 122) and a second part 152 (comprising, for example, a fork inserted between the plate 171 and the part 151) of the head 400 and located at least partly outside the container 122 and at the end of the head 400. The part 151 and / or 152 can hold a roller or applicator or dispensing ball 150 freely rotating and onto which the outlet 24 opens.

[0579] The reservoir 6 and the head 400 thus form a cartridge 200 which can be replaced within the device according to the invention 9000 by unlocking the fastening means 151, 152 and opening a cover 176 fixed on the lower part 180.

[0580] The container 122 is arranged to allow a translational movement (in a housing 181 formed in the reference 176 and / or 180) between the reservoir 6 and the container 122 when the head 400 is tilted.

[0581] The device 9000 includes adjustment means 172 arranged to modify the stiffness of the joint 175. These adjustment means 172 typically include a sliding (metallic) tongue between the parts 170 and 180 so as to have several possible positions more or less distributed over the parts 170 and 180.

[0582] Figure 53 illustrates an embodiment of a device 10000 for distributing a fluid. Only its differences with the device 9000 of Figures 49 to 52 will be described.

[0583] This device 10,000 differs from the device 9,000 in that the head 400 and the container 122 are not tiltable.

[0584] Part 175 is then no longer a joint but a bearing surface arranged to deform the wall 22 of the head 400

[0585] Device 10000 is in the shape of a pen.

[0586] Figures 54 and 55 illustrate an embodiment of a device 11000 for distributing a fluid. Only its differences with device 105 of [Fig. 13] will be described.

[0587] In this embodiment, the bottom wall 21 (or forming a plug or insert 123 pressed into the cap 70) has a convex domed shape on the side of the inner volume of the pocket 2.

[0588] The headgear 70 is formed from a single piece.

[0589] Typically, headgear 70:

[0590] - is formed of only one material, without discontinuity of that material, or,

[0591] - is formed of two or at least two materials and is a part made from of a bi-injection molding or overmolding of material(s) onto another material.

[0592] The cap 70 has a concave domed shape on the side of the inner volume of the pocket 2 and which follows the convex shape of the bottom wall 21 while leaving an intermediate space 2a between these concave and convex shapes so that this intermediate space forms at least in part the inner volume of the pocket 2.

[0593] The majority 2b (at least 70%, preferably at least 80%) of the internal volume of the pocket 2 is located in at least one cavity extending inwards into the bottom wall 21, and is distinct from part 2a.

[0594] The total internal volume of the pocket consists of the sum of parts 2a and 2b.

[0595] The cap 70 is fitted onto the bottom wall 21 without welding. This fitting includes a snap-fit ​​161. The sealing of this fitting is ensured by at least one sealing contact line 260 (or sealing ring) between the cap 70 and the bottom wall 21.

[0596] There may be several sealing contact lines 260 (or sealing rings), possibly grouped together in the form of a sealing strip.

[0597] The edge of the inner volume of the pocket 2 is away and offset from these sealing contact lines 260.

[0598] In the bottom wall 21, an indentation 2b is formed, delimiting at least part of the internal volume of the pocket. The sealing contact lines 260 are spaced apart of this impression 2b or even more generally of the internal volume of pocket 2, sometimes more than 10 millimeters.

[0599] The periphery of the footprint 2b is smaller, at least 30% smaller or even preferably at least 50% smaller, and even 70% smaller, than the periphery of each contact line 260.

[0600] The sealing lines 260 surround but do not border the inner volume of pocket 2.

[0601] In addition to hermetically compressing the flexible wall 108, the ring 109 also serves to retain the supply valve 4, more precisely by compressing the valve foot 4 against a skirt of the bottom wall. The ring 109 is positioned between two cylinders of the bottom wall and is arranged to clip onto the outer walls of the smaller cylinder.

[0602] The supply valve 4 is provided with protective means 204 arranged to protect the valve 4 when a syringe is inserted through the supply port 4L. These means 204, advantageously formed on a ring 109, take the form of a cone or a ring that fits into the base of the valve 4 (on the side of the reservoir 6) and / or include an orifice 41 smaller than the orifice 137 of the base of the valve 4 (preferably a diameter at least 15% smaller).

[0603] The valve 4 is held between the ring 109 and the bottom wall 21.

[0604] Above the contact lines 260, part of the reservoir penetrates inside the bottom wall 21 convex on the side of the pocket 2 but concave on the side of the reservoir 6.

[0605] The volume of pocket 2 is at least 2, 3 or 4 times smaller than the internal volume of cap 70 delimited by a (mean) plane passing through lines 260.

[0606] The cap 70 and the bottom wall 21 are arranged so that the wall 21 is mounted in the cap 70 according to an insert mounting in the cap 70 on the side of the lines 260 and according to an insertion direction 125.

[0607] The bearing surface 25 and the outlet 24 are not lateral, i.e., they are both located on the top of the cap 70, so that: - the product to be distributed exits through outlet 24 with at least one component (20% or more of the exit direction vector) along the insertion direction 125, or the angle between a tangent to the perimeter surface of outlet 24 and direction 125 is between 20° (preferably 45°) and 90° - the support surface 25 is arranged to be moved by a force having at least one component (20% or more of the force vector) opposite to the insertion direction 125, or the angle between a tangent to the surface 25 and the direction 125 is between 20° (preferably 45°) and 90°.

[0608] The support surface 25 includes structures 133 enabling visualization of this surface 25.

[0609] Thus, the device 11000 for distributing a fluid comprises:

[0610] - exit 24,

[0611] - the pocket 2 having an internal volume for containing a fluid, the internal volume of the pocket being delimited: • partly by the cap 70 comprising the movable wall 22 arranged to tilt and / or translate and / or deform by bearing on the support surface 25 so as to modify the internal volume of the pocket, • partly by the bottom wall 21 inserted into the cap 70

[0612] - the distribution valve 5 which, in an open state, allows the passage of fluid from the pocket 2 towards the exit, and, in a closed state, does not allow it.

[0613] - the tank 6 equipped with the wall 118, 108 arranged to contain the fluid,

[0614] - the supply valve 4 which, in an open state, allows the passage of the fluid content in the reservoir towards the pocket, and which, in a closed state, does not allow it.

[0615] In addition, the bottom wall 21 comprises three distinct parts: - a central part 141 partially delimiting the internal volume of the pocket and spaced from the cap 70 so that this space defines at least partially the internal volume of the pocket 2 between the cap 70 and this central part of the bottom wall 21 - an intermediate part 142, surrounding the central part of the bottom wall 21, and arranged to be pressed against the cap 70, this pressing allowing, however, a gap between the cap 70 and the bottom wall 21 with an intermediate space between the cap 70 and the bottom wall 21 of less than two millimeters on average for this space, preferably less than one millimeter on average for this space, and - a peripheral part 143, surrounding the intermediate part of the bottom wall 21, and arranged to form with the cap 70 at least one closed-loop sealing line 260 between the cap 70 and the bottom wall 21

[0616] the intermediate part having an area greater than or equal to 400 square millimeters (preferably greater than or equal to 800 square millimeters) and / or greater than (preferably at least twice greater than) the area of ​​the central part 141 of the bottom wall 21.

[0617] Line 260 forms a loop with a perimeter of at least 200 mm, preferably more than 250 mm or even 300 mm.

[0618] Figures 56 and 57 illustrate an embodiment of a device 12000 for distributing a fluid. Only its differences with the device 11000 of Figures 54 and 55 will be described.

[0619] The bearing surface 25 and the outlet 24 are frontal, i.e. both located on the top of the cap 70 so that: - the product to be distributed exits through outlet 24 with a component that is predominantly (50% or more of the exit direction vector) along the insertion direction 125, or the angle between a tangent to the perimeter surface of outlet 24 and direction 125 is between 20° (preferably 45°) and 90°, and - the support surface 25 is arranged to be moved by a force having at least one component predominantly (50% or more of the force vector) opposite to the insertion direction 125, or the angle between a tangent to the surface 25 and the direction 125 is between 20° (preferably 45°) and 90°.

[0620] Part 2b of the internal volume of the pouch 2 further comprises an additional volume (typically crescent-shaped and / or surrounding the valve 4). This additional volume increases the internal volume of the pouch 2 and thus reduces the pressure within the pouch 2 when pressure is applied to the surface 25.

[0621] The curved or dome-shaped (or spherical) wall 22 or 25 can be replaced by a wall 22b having a pointed apex and / or being conical (with a circular, oval, elliptical, etc. base) or pyramidal (possibly having more than 3 sides) and preferably slightly taller than a spherical cap resting on walls at the base of wall 22b, or a spherical cap resting more towards the apex at a height of 25% of the height of wall 22b (which would rest on average walls if the shape is not spherical). The wall 22b, being at least 0.3 mm taller than wall 22, deforms more gradually. The ratio between the perimeter of the base of pocket 22b and the height of pocket 22b is less than 20 and even less than 19.

[0622] Line 260 forms a loop with a perimeter of at least 200 mm, preferably more than 250 mm or even 300 mm.

[0623] Figures 58 and 59 illustrate an embodiment of a device 13000 for distributing a fluid. Only its differences with device 101 of [Fig. 1] will be described.

[0624] The wall 22 is not in the reservoir 6, the outlet 24 is lateral to the elongation axis of the device and / or the bearing surface, the device includes a filling plug 241 for the reservoir 6 fixed or screwed onto the deformable wall 22. The device is provided with a rigid support wall 128 (formed with the plug 241) to support the deformable wall 22. This support wall 128 is integral with the plug 241 and has a width at least equal to one-third of the width of the deformable wall 22 (measured along a measurement axis parallel or substantially parallel to the bottom wall 21).

[0625] The wall 22 is provided with a skirt 155 having a minimum height at least as high, in the same direction of measurement, as the height at the entrance of the housing 8 on the side of the pocket 2 (i.e. a

[0626] minimum 1mm or 2mm).

[0627] This skirt 155 allows the valve 5 to be inserted into the housing 8 from inside the bag 2 perpendicular or substantially perpendicular to the direction of measurement of the height of this skirt 155.

[0628] Thanks to this skirt 155, the bottom wall 21 takes the form of a flat surface 156 and facilitates the welding of the tank 6 or 14 or 108 to the bottom wall 21.

[0629] Figures 60 to 62 illustrate an embodiment of a device 14000 for distributing a fluid. Only its differences with the device 11000 of Figures 54 and 55 will be described.

[0630] In this embodiment, the side pocket 2, that is to say: - the angle between a tangent to the surface 25 and the direction 125 is between 0° and 45° (preferably 20°).

[0631] The pocket 2 goes around the reservoir 6 and the insert 123 at 360° around the direction 125.

[0632] We have (as with device 101) one or two filling holes 87, 87b each opening onto the inside of the reservoir 6.

[0633] Preferably, there are two of these filling holes, located on either side of outlet 24.

[0634] These filling holes pass through the cap 70 and the insert 123 which together form an end piece 89 (equivalent to the end piece 89 of the device 101).

[0635] A single 310 plug is arranged to simultaneously: - Plug the filling hole(s) 87, 87b, and - Block and / or protect exit 24.

[0636] Form at least in part an applicator 208 and / or a dispensing surface 207. The cap 310 includes a cap 77 which is removable by means of a hinge.

[0637] The cap 310 includes two cylindrical pins 313 that fit with a slight compression into the nozzle 89 at the filling holes 87 and 87b in order to precisely adjust and hold the cap 310 with the nozzle 89 during assembly. This is the predominant fastening method for assembling the cap 310 onto the nozzle 89; additional independent clips further secure the assembly. The diameter of the pins 313 is preferably greater than 3 mm and even greater than 4 mm. Preferably, both holes 87 and 87b are through holes; however, in a version not shown, one of the holes 87 or 87b is blind. This blind hole is called an adjustment or positioning hole.

[0638] The plug 310 includes a housing 312 arranged to receive the end of the distribution piece 23 having the outlet 24. The distribution piece 23 may or may not pass through the plug 310.

[0639] The device 14000 includes a distribution surface 207 onto which the outlet 24 opens.

[0640] The distribution surface 207 has an area of ​​at least 80 mm2 or even of at least 160 mm2.

[0641] The distribution surface 207 can be formed by the plug 310 and the nozzle 89.

[0642] The cap 310 includes an applicator 208 with a domed shape 308 or with a beak shape 309 at least formed in part by 310.

[0643] The insert 123 contains at least in part a deformable 108 which delimits at least in part the internal volume of the reservoir.

[0644] The insert contains at least 20% of the internal volume of the bag 6. The insert contains at least 3 ml or 10 ml, and even at least 20 ml of product to be dispensed, depending on the nature of the device. At least 80%, and even 90%, of the reservoir 6 is deformable on the portion enclosed by the insert.

[0645] The reservoir (its internal volume) does not extend beyond the supply valve 4 towards the outlet; there is no part of the reservoir between the supply valve and the distribution valve along axis 125.

[0646] The wall 108 is blown (typically either blown injected or blown extruded), so as to form a reservoir 6 whose neck is fixed on the insert 123.

[0647] Indexing means 236 (typically including a finger) of the cap 70 relative to the insert 123 are arranged to fit into a hollow 234 of the insert 123.

[0648] With reference to [Fig.62], at least one flow channel 238 is arranged to permit good fluid flow for good filling of the pocket 2, locally increases the space between the insert 123 and the cap 70.

[0649] Line 260 forms a loop with a perimeter of at least 200 mm, preferably more than 250 mm or even 300 mm.

[0650] The container 122 has clipping means 235 on the insert 123 or on the cap 70 and which are arranged to allow disassembly of the cartridge or refill 200.

[0651] The wall 108 is deformable (including inside the insert 123) and is arranged to fold or shrink inwards towards the insert 123 when the reservoir 6 empties of the fluid to be dispensed. At least 10%, 20%, or even 30% of the maximum volume of the reservoir is located inside the insert 123. There is at least one cross-section perpendicular to the direction 125 and passing through the pocket 2 and the reservoir 6 (in particular through a portion of the wall 108 that folds or shrinks inwards towards the insert 123 when the reservoir 6 empties of the fluid to be dispensed), i.e., the pocket 2 and the reservoir 6 are at least partly at the same level, at least 20% or 30% or even 40% of the length of the pouch along the direction 125 is at the level of the reservoir 6. At least 6 mm or 15 mm or even 25 mm of the length of the pouch along the direction 125 is at the same level as the reservoir 6.

[0652] There is at least one cross-section perpendicular to the direction 125 and passing through the deformable wall 25 and the reservoir 6, i.e., the deformable wall 25 and the reservoir 6 are at least partially at the same level. At least 15%, 25%, or even 35% of the length of the deformable wall 25 along the direction 125 is at the same level as the reservoir 6. At least 4 mm, 8 mm, or even 15 mm of the length of the deformable wall 25 along the direction 125 is at the same level as the reservoir 6.

[0653] It is noted that the junction and / or the seal between the cap 70 and the insert 123 can be inside the cap 70 (as illustrated in [Fig.60]) and / or outside the cap 70.

[0654] Pocket 2 is delimited at least in part between insert 123 and cap 70.

[0655] Pocket 2 surrounds reservoir 6 at 360° around direction 125.

[0656] Pocket 2:

[0657] - is distributed over at least 20% or even 30% of the height of the device 14000 the along direction 125, and / or

[0658] - is at least 25mm or 30mm or even 40mm high along the direction 125.

[0659] Figure 63 illustrates an embodiment of a device 15000 for distributing a fluid. Only its differences with the device 14000 of Figures 60 to 62 will be described.

[0660] Compared to the previous embodiment, in device 15000 the flexible wall 108 is fixed (by clamping or otherwise) between the cap 70 and the insert 123.

[0661] Thus, the internal volume of the tank is delimited:

[0662] inside the insert 123, by a rigid wall of the reservoir, formed at least in part by the insert 123 itself. There is at least one cross-section perpendicular to the direction 125 and passing through the pocket 2 and through the reservoir 6 (and through the insert 123; and also through the cap 70), i.e. the pocket 2 and the reservoir 6 are at least partly at the same level.

[0663] However, when the reservoir 6 is filled to its maximum with the fluid to be dispensed, there is not at least one cross-section perpendicular to the direction 125 passing through the pouch 2 and through the flexible wall 108 (folding or shrinking inwards towards the insert 123 when the reservoir 6 empties of the fluid to be dispensed)!! There is at least one cross-section perpendicular to the direction 125 (closer to the valve 4 than the cross-section previously described) and passing through the pouch 2 and through the reservoir 6 (in particular through a rigid part 240 of the reservoir wall and not folding or shrinking not reducing towards the inside of insert 123 when reservoir 6 empties of the fluid to be distributed). - On the other hand, when the reservoir 6 is emptied of a certain quantity of the fluid to be distributed and the flexible wall 108 has folded or reduced itself towards the inside of the insert 123, there is at least one cross-section perpendicular to the direction 125 passing through the pocket 2 and through the flexible wall 108 as illustrated in [Fig.63]. - outside of insert 123, through flexible wall 108.

[0664] The volume of the reservoir 6 outside the insert 123 is at least 40% greater than the volume of the reservoir 6 inside the insert 123.

[0665] Such an assembly is made possible thanks to the holes 87 allowing the insert 123 to be pulled towards the cap 70.

[0666] Figures 64 to 66 illustrate an embodiment of a device 16000 for distributing a fluid. Only its differences with the device 14000 of Figures 60 to 62 will be described.

[0667] In this embodiment 16000, the insert 123 extends outside the cap 70.

[0668] The internal volume of the reservoir 6 is no longer delimited (even in part) by a flexible deformable wall 108, but is delimited by the insert 123 and by a mobile piston 86 moving in the insert 123 according to the quantity of fluid to be distributed contained in the reservoir 6.

[0669] This embodiment 16000 includes a vent 321, which allows air to circulate between the outside of the device 16000 and the part (of variable volume depending on the position of the piston 86) located in the insert 123 but outside the reservoir 6.

[0670] Vent 321 passes through pocket 2.

[0671] The wall 22 (preferably flexible) is wedged between the cap 70 and the insert 123.

[0672] There is at least one cross-section perpendicular to the direction 125 and passing through pocket 2 and through reservoir 6 (and through insert 123 but not through cap 70), i.e. pocket 2 and reservoir 6 are at least partly at the same level.

[0673] The device 16000 includes sealing means 233 between the insert 123 and the wall 22 at the vent 321.

[0674] The pocket 2 is delimited at least in part between the insert 123 and the wall 22 held between the cap 70 and the insert 123.

[0675] Pocket 2 surrounds reservoir 6 at 360° around direction 125.

[0676] Pocket 2:

[0677] - is distributed over at least 30% (preferably at least 50%) of the height of the device 16000 along direction 125, and / or

[0678] - is at least 30 mm or 40 mm or even 50 mm high along the direction 125.

[0679] The insert 123 includes the bottom wall 21.

[0680] The internal volume of pocket 2 is at least twice as small (preferably at least four times smaller) as the internal volume of reservoir 6.

[0681] Holes 237 pass through the insert 123 and connect two parts of the pocket 2: the part located between the insert 123 and the cap 70 and the part located between the insert 123 and the flexible deformable wall 22.

[0682] Insert 123 therefore has several functions: - maintaining the wall 22 between the insert 123 and the cap 70 - wear the holes 237 - to delimit at least partially the internal volume of pocket 2 - to delimit at least partially the internal volume of the tank 6 - guide the movement of the piston 86 - maintenance of sealing means 233 - carry one end of vent 321.

[0683] All these functions are therefore ensured by a part 123 of the tip 89.

[0684] The nozzle 89 (more precisely the insert 123) forms the side walls of the reservoir 6.

[0685] In this embodiment 16000, we have: - 87, 87b tank filling holes 6 - holes 187, 187b for filling pocket 2.

[0686] The reservoir 6 is located between the valve 4 and the vent 321.

[0687] There is at least one cross-section perpendicular to the direction 125 and passing through pocket 2 and through reservoir 6 (and through insert 123 but not through cap 70), i.e. pocket 2 and reservoir 6 are at least partly at the same level.

[0688] The internal volume of the pocket 2 is delimited at least in part between the insert 123 and the wall 22 maintained between the cap 70 and the insert 123.

[0689] Wall 22 has an external pocket shape.

[0690] The wall 22 forms both lateral outer walls and an outer wall of bottom of the device on the side of wall 91.

[0691] The cap 70 is fixed to the open end of the pocket 2 formed by the wall 22.

[0692] Reservoir 6 is located at least partly inside pocket 2.

[0693] In an unshown variant of [Fig.64], the reservoir 6 is delimited at least in part by a flexible wall 108 as in [Fig.55] or 56, and the valve 4 and the vent 321 are located on the same side of the reservoir 6. The vent 321 passes through the insert 123 and the cap 70. The wall 22 (preferably flexible) is wedged between the cap 70 and the insert 123.

[0694] Figure 67a illustrates one embodiment of a 17000 device for distributing a fluid. Only its differences with device 16000 in figures 64 to 66 will be described.

[0695] In this embodiment, the insert 123 extends outside the cap 70.

[0696] As with the embodiment of [Fig. 56], the internal volume of the reservoir 6 is delimited by a flexible deformable wall 108 closed by a bottom wall 91 immobilized by the insert 123.

[0697] This flexible wall 108 is inside the insert 123.

[0698] The device 17000 includes a refill connector 225 arranged to allow refilling of fluid inside the device 17000 (more precisely inside the reservoir 6) without this fluid passing through the pouch 2 or the distribution valve 5 or the supply valve 4.

[0699] Connector 225 includes a charging valve which:

[0700] - at rest is closed, and

[0701] - is arranged to open when means 225 are connected to a source of fluid to be dispensed.

[0702] Connector 225 is removable.

[0703] The reservoir 6, more specifically the wall 91, emerges outwards so as to form a neck having a slope 224 avoiding trapping air in the reservoir 6.

[0704] In addition, sealing means 218 of the device, more precisely in the connector 225 or at the neck 85, prevent air from entering the reservoir 6 during the refilling of the reservoir 6.

[0705] The valve of connector 225 opens into reservoir 6.

[0706] Connector 225 passes through wall 91.

[0707] Insert 123 is stuck between wall 22 and wall 91.

[0708] There is at least one cross-section perpendicular to the direction 125 and passing through pocket 2 and through reservoir 6 (and through insert 123 and through wall 108), i.e. pocket 2 and reservoir 6 are at least partly at the same level.

[0709] The internal volume of the pocket 2 is delimited at least in part between the insert 123 and the wall 22.

[0710] The pocket 2 (and the wall 22) surrounds the reservoir 6 at 360° around the direction 125.

[0711] Reservoir 6 is located at least partly inside pocket 2.

[0712] Connector 225 is at opening 87 and is plugged by plug 310. The 225 connector can be used to fill both pocket 2 and reservoir 6.

[0713] A cover or handle 226 covers the neck 85 of the connector 225 and the wall 91 of in order to hide them from outside the device.

[0714] In another variant not shown on the connector 225 and / or the valve 4 includes a "duck valve" type valve, to allow the introduction of a filling tube 46 to fill the reservoir 6 and / or the bag 2 with fluid to be dispensed.

[0715] The filling tube may include two holes, of which: - a first hole 68 (preferably at the end of the filling tube inserted into the device) which opens into pocket 2, and - a second hole 67 (preferably located laterally along the filling tube) which opens into the reservoir 6.

[0716] It is noted that in this variant the recharging is not done under pressure.

[0717] A spring element 212 is interposed between the insert 123 (more precisely between the bottom wall 21 of the insert 123) and the wall 22. This element 212 can be present in each of the variants of figures 67a, 67b or 67c or even 64.

[0718] The wall 22 is fixed on the insert 123, more precisely in a groove of the insert 123. The device includes clipping means 213 of the pocket 22 on the insert 123, more precisely a ring 213 is clipped into a groove of the insert 123.

[0719] This ring 213 further includes means for fixing the applicator 208 such as a rim 223 or rim section surrounding the device laterally so as to retain the rim of an applicator 208. The applicator is removable and is provided around its perimeter with a rim element that is less elastic and attaches to the rim 223.

[0720] The wall 22 is flexible and is injected in thermoplastic elastomer for example in TPO.

[0721] The distribution valve 5 is inserted into the wall 22. The valve 5 is more flexible than the wall 22 at the level of an overthickness of the wall 22 in which the valve 5 is housed.

[0722] In another variant illustrated in [Fig. 67c], the cap 70 comprises several walls 22, each wall 22 being equipped with its own valve 5 opening onto a pocket 2 common to all the valves 5. This allows the product from the reservoir to be distributed over a larger area. Optionally, all these walls 22 are covered by the same porous surface 208. Volumetric parts 217, typically made of foam, are arranged to smooth out differences in level between the parts of the cap 70 with and without walls 22.

[0723] A method for filling device 17000, but which would also be applicable to any embodiment or variant of the device according to the invention equipped with the orifice 87, is as follows: 1. The reservoir 6 and / or the bag 2 is filled through the orifice 87 when this orifice is not equipped with the connector 225, as illustrated in [Fig.67b], or is only equipped with a "duck valve" type valve; air 210 may escape.

[0724] Typically, a filling tube 46 comprising two or at least two holes can be used, of which: - a first hole 68 (preferably at the end of the filling tube inserted into the device) which opens into pocket 2, and - a second hole 67 (preferably located laterally along the filling tube) which opens into the reservoir 6;

[0725] then 1. Port 87 is fitted with connector 225 if the device does not include a "duck valve" used for filling in step 1. 2. Empty at least partially the reservoir 6 and / or the bag 2 using the device, then 3. The reservoir 6 and / or the pouch 2 are refilled through the orifice 87 while this orifice is equipped with the connector 225 and / or a sealing means 218, as illustrated in [Fig. 67a] and 67d,

[0726] In a variant, illustrated in [Fig.67d], of figures 67a, 67b and 67c, the device according to the invention does not include a connector 225.

[0727] Filling is done through a "duck valve" type refilling valve 219 which opens into the reservoir 6.

[0728] Two filling means or heads 220 and 221 allow for filling respectively: - The reservoir 6 and the pouch 2 for the long tool 220. During the first filling of the reservoir 6 and the pouch 2 by the tool 220, air 210 from the reservoir 6 may escape through the valve 219; - The reservoir 6 for the tool 221 is shorter than the long 220. The tool 221 or a neck 75 opening onto the valve 219 includes a seal 218 placed between the neck 75 and the tool 221, so that during the second filling of the reservoir 6 by the tool 221, air 210 cannot pass through the valve 219 and in particular cannot enter the reservoir 6 through the valve 219;

[0729] We will now describe, with reference to figures 69a to 70c, different embodiments of the device according to the invention.

[0730] All these embodiments of figures 69a to 70f have in common the continuity of material or overmolding or bi-injection between:

[0731] - the cap 70 (if present, otherwise generally the supporting wall 25)

[0732] - the deformable wall 22,

[0733] ​​- a movable wall 420, arranged to translate, inside a conduit or cylinder 430 or outside a piston 430, and whose translational movement is guided by a rail 112 which is coupled to a slide 113, the rails 112 and / or a slide 113 being thus arranged to guide the cap 70 (or the bearing surface 25).

[0734] The rail 112 or the slide 113 is integral with the cap 70 (more precisely formed in the cap 70), while respectively the slide 113 or the rail 112 is integral of the bottom wall 21 or of part 430, (or fixed part delimiting at least part of the internal volume of the pocket). This rail / slide assembly can be replaced or supplemented by another rod / cylinder assembly arranged so as not to compress the fluid does not delimit the pocket 2.

[0735] Preferably at least one rail / slide pair is arranged to have transverse support (perpendicular to the support direction 140) in all directions.

[0736] Outlet 24 is equipped with a nozzle 59 arranged to generate a spray.

[0737] We will now describe, with reference to [Fig.69a], an embodiment of device according to the invention. This embodiment will only be described for its differences from the embodiment of [Fig.4].

[0738] In this embodiment, the deformable wall 22 does not at least partially delimit the internal volume of the pocket 2. The deformable wall 22 is in contact with an air pocket 34 (an external pocket 34 comprising air).

[0739] In this embodiment, the movable wall 420 delimits at least in part (together with the conduit 430) the internal volume of the pocket 2.

[0740] The cap 70 further includes a distribution nozzle 30 carrying the outlet 24. This dispensing nozzle 30 extends laterally beyond the width of the side walls 118 delimiting or containing the reservoir 6. The dispensing nozzle includes the dispensing housing 8 which extends to or beyond the side walls 118.

[0741] The movable part 420, pushed in to the maximum in or around the part 430, leaves a part 36 of the part 430 in which the part 420 has not pushed in by a length of at least 20 mm or even at least 30 mm.

[0742] The pocket 2 leaves a part 36 of a length of at least 20mm or even 30mm between the feed orifice 41 and the bottom wall 21.

[0743] The beak 30 is equipped with a nozzle 59 arranged to generate a spray.

[0744] This embodiment further includes a rib 37 from the bottom wall 21 arranged to prevent the pocket 108 from sinking into the device around the pocket 2, in particular around its part 36.

[0745] The whole 108, 112, 6, 87, 2, 70 122 is placed in a case 170, 180 formed by an assembly of an upper part 170 of the case and a lower part 180 of the case.

[0746] The nozzle emerges from the housing, preferably: - Either through a hole formed in the upper part 170 - Either through a hole formed between the upper part 170 and the lower part 180.

[0747] The beak 30 is part of the cap 70 in the form of a single piece of the same material (without discontinuity of material).

[0748] A cartridge 200 is formed by assembling the reservoir 6 and the chamber 2 (and also preferably the cap 70 and / or the valve 4 and / or the valve 5).

[0749] During the assembly of parts 170 and 180, a skirt 145 of the upper part blocks the cartridge or refill 200 in order to prevent movement of this cartridge 200 within this embodiment of the device according to the invention, even when pressing on the cap 70.

[0750] With reference to Figures 69b and 69c, the upper part 170 comprises:

[0751] - a part 178 forming a button arranged to press on the headgear 70

[0752] - a part 177 forming a movable ring surrounding the button 178

[0753] - an intermediate part 179, located between parts 177 and 178, movable, comprising clipping means arranged to clip to the lower part 180, and arranged to unclip from the lower part when the part 177 is pulled.

[0754] We will now describe, with reference to Figures 70a to 70h, an embodiment of device 19000 according to the invention. This embodiment will be described, unless otherwise stated, only for its differences from the embodiment of [Fig. 4].

[0755] In this embodiment, the deformable wall 22 does not delimit at least in part the internal volume of the pocket 2.

[0756] The deformable wall 22 may include elastic tabs extending over the bottom wall 21 outside the piston 420.

[0757] In this embodiment, the movable wall 420 delimits at least partially (together with the conduit 430) the internal volume of the pouch 2. The outlet 24 is equipped with a nozzle 59 arranged to generate a spray. The device 19000 does not include a cap 70. The base piece 289 includes the base wall 21. The base piece 289 includes a means 89 for attaching it to the reservoir or the nozzle 89.

[0758] The deformable wall 22 is in contact with an outer pocket 34 containing fluid surrounding the pocket 2, connecting the pocket 2 to the reservoir via an orifice 163 and arranged to receive fluid from the reservoir. The volume of the pocket 34 is greater than the volume of the pocket 2, preferably at least twice as large.

[0759] A button 250 comprising the deformable wall 22 delimits with the bottom piece 289 or 245 an elastic pocket 255 comprising the pocket 2 and the pocket 34, the pocket 34 in this device is arranged to form a fluid passage from the reservoir 6 to the pocket 2.

[0760] The elastic pocket 255 is delimited by the bottom wall 249 of the bottom piece 289 or 245 and the button 250. The button 250, having the deformable wall 22, comprises a continuous or discontinuous curve that can be interpolated by two or three discontinuous slopes, of which:

[0761] - a first slope 50 or central part 50 preferably non-deformable or slightly deformable with respect to the wall 22 preferably forming an angle between 0° and 20° with respect to the bottom wall 21 or with respect to the plane perpendicular to the axis 290 of compression of the pocket 2.

[0762] - around the first slope, a second slope 51 of the deformable wall 22 forming an angle between 25° and 75° with respect to the bottom wall 21 or with respect to the plane perpendicular to the axis 290 of compression of pocket 2.

[0763] - around the second slope, a third slope 52 of the deformable wall 22 forming an angle between 50° and 100° with respect to the bottom wall 21

[0764] This first slope or central part 50 located substantially in the center of the button is more rigid than the deformable wall 22 is surrounded by the deformable wall 22 (typically formed by a thicker wall) therefore more rigid than the slopes 51 and / or 52.

[0765] The deformable wall 22 of the button is integral with the central wall 50.

[0766] This extra thickness of the slope 50 or central wall 50 constitutes a means of braking 55 of the wall 22, but also a hollow and / or a bump at the rail / slide couple or the fitting of the piston 420 in the conduit 430 can increase this braking.

[0767] The braking means 55 are created by the part 50 arranged to deform a larger perimeter of the wall 22. A support would be more localized without part 50. The wall 50 comprises a surface area of ​​at least 50 mm², even at least 70 mm², and even at least 100 mm², having a movement guided by a guide means 251 in order to prevent the wall 50 from tilting under the maximum support force. The central wall 50 of the button 250 has a width of at least 8 mm, even at least 10 mm, and even at least 12 mm (measured on the plane perpendicular to the compression axis 290 of the pocket 2). The compression axis 290 of the pocket corresponds to the axis of movement of the part 50 and is parallel to the guide means 251.

[0768] The support force is arranged to decrease by at least 30% or at least 40% at the beginning of the movement of the central part 50 (from its rest position). Preferably, the maximum support force 140 on the support surface 25 (in the undeformed state of the wall 22) to trigger the deformation of the wall 22 is at least 1.6 times and even 1.8 times or even at least 2 times greater than the force that must be exerted on the button to continue the deformation between the first and second millimeters of displacement of the support wall 25 towards the bottom wall 21 and / or between the second and third millimeters of displacement of the support wall towards the bottom wall 21.

[0769] The guiding means 251 comprise at least one guiding wall and preferably at least one rail 112 and / or one slide 113, these means of The guide means 251 are fixed to the central wall 50. The guide means 251 preferably comprise only 1 to 3 guide means (or rail 112 and / or a slide 113), but preferably two guide means (or rail 112 and / or a slide 113). In the case of a guide means, it may comprise an open cylinder, preferably with an opening of at least 240 degrees.

[0770] The central wall 50 of the button 250 comprises walls thicker than the wall 22 and / or stiffened by the guiding means 251 and integral with the wall 22 or parts of the wall 22 if it includes, for example, bands. The guiding element 251 is a wall oriented towards the bottom wall 249 of the elastic pocket 255 and substantially parallel to the direction 140 and 290, preferably substantially perpendicular to the wall 50 (perpendicular to the surface of the wall 50 on the side of the elastic pocket 255).

[0771] The guiding means 251 (more precisely the rail 112 and / or the slide 113) is arranged to guide the bearing surface. The element 251 is placed in the pocket 34 but not in the pocket 2; it does not pass through the bottom wall 249 (or the bottom wall 21).

[0772] The guide means 251 of the button 250 (or guide wall 251) and the central wall 50 are arranged to translate and to guide the bearing surface 25.

[0773] The button guide means 251 are arranged to cooperate with a fixed element 252 and / or hollow 252 of the bottom wall 249 of the bottom part 289.

[0774] The movable wall 420 is integral with the central part 50, which is itself integral with the wall 22; there is continuity of material between the deformable wall 22, the wall 50 and the piston 420.

[0775] The pocket 34 surrounds the pocket 2 and is delimited by the wall 22 and is delimited in part by the wall 50 for at least 10% and even at least 20%.

[0776] The wall 22 of the button 250 forms a means of returning the movable wall 420 and the wall 50, the piston 420 being arranged to translate, inside the conduit 430 or outside the piston 430. Around the piston 420 and the conduit 430 or piston 430 the guiding means 251 cooperates with the bottom wall 249 (a fixed element 252 and / or hollow 252) (preferably rails 112 and / or slides 113) being arranged to guide the central part 50 and the wall 420 by translation. Rail 112 or slide 113 is integral with part 50, while slide 113 or rail 112, respectively, is integral with the bottom wall 249. The guide means 251 are arranged around piston 420, preferably spaced at least 7 mm apart and even at least 10 mm apart (measured with respect to the plane perpendicular to the compression axis 290 of pocket 2). The pair 251 / 252 is arranged so as not to compress the fluid. The pair 251 / 252 does not define the pocket 2.

[0777] Preferably the wall 50 of the button 250 is substantially in continuity with the wall 22. The pockets 2 and 34 have an internal volume delimited in part by the wall 50, pressure on the bearing surface 25 causes a simultaneous reduction of the pockets 2 and 34.

[0778] The wall 22 is integral with the wall 50, which is itself integral with the movable wall 420 and the rails 112 and / or slides 113. The movable wall 420 is arranged to translate, the translational movement being guided by the means 251 cooperating with a fixed element 252 and / or hollow element 252, preferably a rail 112 / slide 113 pair. Each rail 112 and / or slide 113 is arranged to guide the bearing surface 25. The central wall 50, the deformable wall 22, the piston 420, and the guiding means 251 (or wall 251) are made in one piece without discontinuity of material, preferably of polypropylene with a flexural modulus of at least 300 MPa and even at least 500 MPa and less than 14,000 MPa (Megapascals).

[0779] On average, this extra thickness of the wall 50 is preferably at least 2 times thicker than parts 51 and / or 52 of the wall 22.

[0780] The part of the wall 22 forming the slope 50 is at least 1.5 times and even 2 times wider (along a measurement axis parallel or substantially parallel to the bottom wall 21) or (measured on the plane perpendicular to the compression axis 290 of the pocket 2).

[0781] With reference to [Fig. 70b] and [Fig. 70c], in a variant of [Fig. 70a], part 50 is substantially parallel to the bottom wall 21, part 51 is absent or only minimally present, and part 52 represents at least 70% of the wall 22, or even the entire wall 22 forms an angle of substantially 90° with the bottom wall 21 (substantially 90° with respect to the plane perpendicular to the compression axis 290 of the pocket 2). Part 52 (the lateral part of the button or the wall 22) comprises, at least in part, an elastomeric material that is more flexible than part 50. Parts 52 and 50 of the wall 22 are made in one piece by overmolding or bi-injection. With reference to [Fig.70b] the wall 22 and the distribution piece 23 are made in one piece called body 246. A bottom piece 245 including the bottom wall 21 closes the pocket 2, preferably by welding or fitting with the body 246.The base part 245 does not include the means for attaching it to the tank 89 (or the nozzle 89).

[0782] The deformable walls 22 of the elastic pocket 255 and of the pocket 2 are formed at least in part by a foldable wall 301 (preferably forming a closed curve) comprising an assembly of strips or parts 146, 147 (preferably by successive alternation of parts 146 and 147). The parts 146 are arranged so as to be able to deform or even buckle under the action of a force exerted on the bearing surface 25. The parts 147 are formed of a flexible material, preferably elastic (more flexible than the strips or parts 146), and / or by openings or passages of fluid allowing the passage of fluid between the internal volume of the pouch 2 and the reservoir 6.

[0783] During buckling or sudden deformation of parts 146, each strip or part 147 is widened such that:

[0784] - the L2 space between two strips 146 after buckling (or sudden deformation) is superior to the L1 space between two 146 strips before buckling, and / or

[0785] - the circumference of the closed curve after buckling (or sudden deformation) is greater than the circumference of the closed curve before buckling (or deformation).

[0786] The strips 146 form elastic tabs, preferably made of a rigid or semi-rigid material (for example, a polypropylene with a flexural modulus between 500 MPa and 1200 MPa), capable of resisting a bearing force in a direction 140 in order to create a yield force up to buckling (or sudden deformation) of the parts 146. The strips 147 are preferably made of an elastomer (for example, a TPO with a flexural modulus between 10 MPa and 80 MPa). The parts 147 are arranged to form additional restoring means to the restoring means of the parts 146 (to restore the rest position after the removal of the bearing force 140 on the wall 25).The parts 147 are arranged to reduce the lateral stresses (at L2 in the plane perpendicular to the compression axis 290 of pocket 2) of the strips 146, preventing deformation beyond the elastic limits of the material. The strips 147 are arranged to absorb the majority of the lateral deformation L2 less LL. Preferably, the strips or parts 147 are wider than the strips or parts 146, these strips or parts 146 and 147 being made by overmolding or bi-injection in one piece with the central part 50, the strips 146 being of the same material as the part 50. The strips or tabs 146 extend over the height of a cylinder forming an angle of less than 30 degrees with respect to the axis 290. Preferably, the wall 301 forms substantially a cylinder generated by the strips 146.

[0787] The button 250 includes on its lateral part the folding wall 301 or wall 22 surrounding the movable wall 420 and including the guide means 251 between the movable wall 420 and the folding wall 301. Preferably the wall 22 or 301 includes at least 3 strips or tabs 146 making an angle of less than 30 degrees with respect to the axis 290, and includes at least 2 flexible parts 147 between two tabs 146.

[0788] In a variant compared to [Fig. 70b], and with reference to Figures 70d, the foldable wall 301 partially delimits the pocket 2, the wall 50 includes the guide means 251 surrounding the foldable or deformable wall 22. The button 250 includes the foldable or deformable wall 301 in its central part and includes the guide means 251 outside the foldable wall. Note that the wall 301 is waterproof, parts 146 and 147 completely surround pocket 2, parts 147 do not include a passage but flexible material (flexible parts 147).

[0789] The button 250 includes in its central part the foldable wall 301 or deformable wall 22, and includes the guide means 251 at the end of the wall 50 (forming a skirt) surrounding the foldable wall 301 or deformable wall 22. It is noted that the guide means 251 includes a single guide wall forming a cylinder comprising rails and / or slides formed by slots inside or outside the cylinder.

[0790] Pocket 2 is delimited in part by a foldable or deformable wall 301 22 arranged to plug or close the feed orifice 4L The movable or deformable wall 22 comprises a flexible part 435 obtained preferably by overmolding or bi-injection on a part 146 more rigid than the part 435 in the same material as the flexible parts 147, this flexible part 435 is in the pocket 2 and is oriented towards the bottom wall. Part 435 is not mobile relative to wall 22 (except for material compression) and is disposed on a part of wall 22 or a part attached to wall 22 such as part 50, guide means 251 or cap 70. Part 435 is arranged so that when the support force 140 is exerted on the support surface 25 from outside the pocket (2), it transmits at least part of this support force 140 to the flexible part 435 by pressing on the bottom wall or a part attached to the bottom wall.It is noted that the fluid passes through an orifice 41 formed in the bottom wall and / or passes through a variable orifice 41 arranged to close or open between the wall 22 and the bottom wall 21, more precisely the periphery of the wall 22 on the side of the bottom wall comprising a flexible rim 426 which in a closed position is arranged to press against or fit into the bottom wall 21 to block or limit the passage of fluid from the pocket 2 to the reservoir 6 and / or the part 34. In the open position, the wall 22 is arranged to move away from the bottom wall 21 to allow the fluid to enter the pocket 2 (this open position is obtained when the pressure on the support wall 25 is released, in particular if the closure between the part 426 and the bottom wall is not completely watertight to avoid a suction effect). The wall 22 with its border 426 forms a valve 4.In the case of the orifice 41 formed in the bottom wall (which can be combined with the variable orifice between wall 22 and wall 21), when a support 140 is applied to the bearing surface 25, the flexible part 425 blocks the passage of fluid from the pouch 2 to the part 34 or the reservoir 6; when the support 140 is released, the device is arranged so that the part 425 can move away from the wall 21, for example, by having a slight indentation in the flexible part 425 to break the seal between wall 22 and wall 21.

[0791] In a variant compared to [Fig. 70a], and with reference to Figures 70e to 70h, wall 51 is present but not wall 52; wall 51 makes an angle of more than 35 degrees with respect to the elongation plane of the device. Preferably, the device... includes side walls 22 having on average a single slope 51 of more than 35 degrees, or more than 40 degrees, or even more than 45 degrees (measured on the plane perpendicular to the compression axis 290 of the pocket 2). The button 250 or the deformable wall 22 is not welded to the bottom wall 249 but simply rests against the bottom wall, which is equipped with locking means 243 to prevent lateral slippage of the wall 22. The button 250 is clipped to the bottom piece 289 or 245. Preferably, the guide means 251 includes at least one clip 247 for clipping to the element 252 (fixed and / or hollow element of the bottom wall); more specifically, the rail 112 or the slide 113 of the button clips to the slide 113 or the rail 112 of the bottom wall, respectively. We note holes 256 in the button 250 in the part 50 so as to form the clip(s) 247 and holes 256 in the bottom wall 249 so as to form the hollow(s) 248.The device includes an indexing means 244 for positioning the button 250. In the rest position, the valve 4 is open, the opening being formed by the space between the end 420a of the piston 420 and the end of the cylinder 430a. Preferably, the opening 428 of the valve 4 (the sum of the spaces between the end of the piston 420a and the cylinder 430a in the rest position) is at least 120 degrees with respect to the axis of the piston 420. Preferably, the opening 428 is at least 1 mm², preferably at least 2 mm². The opening 428 extends along the axis of the reservoir 6, when the device is filled in a direction 87a corresponding to the elongation of the reservoir, with a non-viscous fluid such as water, one part of the opening 428 is in contact with the fluid while the other part of the opening 428 is in communication with the outside of the device and water enters the pocket 2.As indicated in document WO2019002527, the device includes a step of filling at least part of pouch 2 while it is open in communication with the outside of the device.

[0792] With reference to Figures 70g and 70h, preferably the width 54a of the central wall 50 is greater than 0.25 times, or even 0.30 times and even greater than 0.40 the width 54b of the wall 22 (without taking into account the edge of the wall 22 pressed against the bottom wall and measured on the plane perpendicular to the compression axis 290 of the pocket 2. With reference to [Fig.70h], preferably the width 54a of the central wall 50 is greater than 0.3 times, or even 0.4 times and even greater than 0.5 times the width 54c corresponding only to the width of the wall 22 which moves or deforms (measured on the plane perpendicular to the compression axis 290 of the pocket 2).

[0793] We will now describe, with reference to Figures 70i, an embodiment 20000 of the device according to the invention. This embodiment will be described only for its differences from the embodiment of [Fig. 70b].

[0794] Parts 146 and 147 can be seen from outside the device. The pocket 34 surrounding the pocket 2 (between the foldable wall 301 and the piston 420 / cylinder 430 pair) preferably contains air and does not include a fluid inlet orifice 163.

[0795] Parts 147 are formed by a flexible material and / or by air passages. Parts 146 and 147 surround (completely or not) the sealed piston 420 and the conduit or cylinder 430 which delimits the internal volume of the pocket 2. The cap 70 includes at its base shoulders 302 which extend outwards from the device. The cap 70 is superimposed on the foldable wall 301 at the shoulders 302. The bands or parts 146 and 147 are substantially parallel to the elongation axis of the device and / or to the axis of the cap 70 and are made in one piece by overmolding or bi-injection with the cap 70. In a variant not shown in relation to [Fig.70d], the piston 420 / cylinder 430 is replaced by the foldable wall 301, the foldable wall is in the cap 70 and the guiding means are integral with the wall 302 of the cap 70.

[0796] We will now describe, with reference to Figures 71 to 73a, an embodiment of device 21000 according to the invention. Unless otherwise stated, this embodiment will only be described for its differences from the embodiment of [Fig. 70a].

[0797] In this embodiment the pocket 2 is outside the reservoir, the support surface 25 includes the central wall 50. In this embodiment, the movable wall 420 does not delimit at least in part the internal volume of the pocket 2.

[0798] In this embodiment, the deformable wall 22 at least partially delimits the internal volume of the pouch 2. The elastic pouch 255 coincides with the pouch 21, and the bottom wall 249 coincides with the bottom wall 21 (compared to device 19000, in the description the pouch 255 can be replaced by the pouch 2 and the bottom wall 249 by the bottom wall 21). There is no piston 420 and cylinder 430 forming the pouch 2; the fluid enters the pouch 2 directly through the diaphragm of the inlet valve 4 without passing through an intermediate pouch 34.

[0799] In this embodiment, the wall 22 is arranged to press directly or indirectly on the valve 4. More precisely, the wall 22 comprises at its periphery a portion 53 arranged so that, when a support force 140 is applied to the support wall 22 from outside the bag 2, it transmits at least part of this support force 140 to the supply valve 4, either directly to the supply valve 4, or, as shown in [Fig. 73a], through a support member 139 of the supply valve comprising a tab 138 arranged to press on the supply valve 4, more precisely on its membrane, by pressing the supply valve 4 against the bottom wall 21. When pressure is applied to the wall 25, the portion 53 of the wall 22 is arranged to deform before the other parts of the wall deform. deformable 22, more precisely before the deformation The abrupt movement of walls 51 and 52. Wall 50 of button 250 is arranged to move by translation towards the bottom wall, guided by the rail / slide assembly. The support member 139 of the supply valve 4 is integral with the bottom wall component 21. The member 139 belongs to the same part as the bottom wall 21 and is formed from the molding of the bottom wall 21 and the housing 8 of the distribution valve.

[0800] The supply valve 4 (more precisely on its diaphragm) includes a bubble or bump 135 (to join the pin 139 and have a more centered force) which can be in contact with the bottom wall 21 by forming a spring.

[0801] The portion 50 integral with the wall 22 forming the slope 50 has a width 54a (along a measurement axis parallel or substantially parallel to the bottom wall 21 or measured on the plane perpendicular to the compression axis 290 of the pocket 2) equal on average to at least 0.3 times or even at least 0.4 times the width 54b of the pocket 2 (measured for the portion of the pocket 2 closest to the wall 21 and measured along a measurement axis parallel or substantially parallel to the bottom wall 21). The width 54a of the central wall 50 is greater than 0.4 times or even 0.5 times the width 54c corresponding only to the portion of the wall 22 that moves or deforms towards the wall along the support axis 140 (measured on the plane perpendicular to the compression axis 290 of the pocket 2).

[0802] In this device with reference to [Fig.73] we note a reinforcement 131 of the wall 50 attached to at least 2 guide walls 251.

[0803] The wall 22 and / or the bottom wall 22 is provided with a skirt 155 having a minimum height at least as high, in the same direction of measurement, as the height at the entrance of the housing 8 on the side of the pocket 2 (i.e. minimum of 1.5mm or 3mm).

[0804] This skirt 155 allows the valve 5 to be inserted into the housing 8 from inside the bag 2 or the outlet 24 perpendicular or substantially perpendicular to the direction of measurement of the height of this skirt 155.

[0805] Thanks to this skirt 155, the bottom wall 21 takes the form of a flat or substantially flat surface 156 and facilitates the welding of the bottom wall 21 onto a face 56 of the flexible bag 14 forming the reservoir 6.

[0806] The bag 14 is an open film before being welded to the wall 21, then is folded (along the fold 144) and closed on itself to form the interior space of the reservoir 6, the outlet 24 is lateral the dispensing nozzle 30 is located at the fold 144. The dispensing nozzle 30 protrudes by less than 3 mm and even protrudes by less than 1 mm from the edge of the bag 14 once formed.

[0807] With reference to [Fig. 72], in another variant part 53 comprises a flexible part 435 which may or may not surround the deformable wall 22, the deformable wall being arranged so that, during an exercise of the support force 140 on the support surface 25 from outside pocket 2, transmit at least part of this support force 140 to the flexible part 435.

[0808] The features of device 19000 can be combined with the features of device 21000, in particular pocket 2 can include a successive alternation of parts 146 and 147.

[0809] It is noted that the portion of the wall 22 forms a hollow 57 which surrounds the movable part of the wall 22, thus the force 140 is better centered, the movable part of the wall 22 is protected, and the thickness of the device is reduced for the same distributed dose. It is noted that the deformable wall 22 forming the hollow 57 is located opposite the orifice of the valve housing 8. There is a straight line passing through the distribution valve housing 8 and intersecting the deformable wall 22 three or four times.

[0810] With reference to Figures 74, 75 and 76, each of the embodiments or variants described above, comprising a deformable wall 22 (preferably at least partially delimiting the internal volume of the pouch 2) which is not located inside the reservoir 6, may be equipped with a button 162 having a screw thread 164, preferably screwed to an element integral with the wall 22 which is located at the top of the concave shape of the wall 22 (for example, to the cap 70 if the latter is located on the top of the wall 22 (Figures 4, 13, 14, 16, 18, 23, 24, 30, 32, 34, 35, 40, 45, 69 in the example of [Fig. 75]) or to a rod or support 166 added to the top of the wall 22 equipped with a screw thread (figures 19, 38, 56, 58, 72 in the example of [Fig.74])).

[0811] This screw thread 164 is arranged to, depending on the screwing of the cap 162 onto the wall 22, adjust a space between the cap 162 and the bottom wall 21 or another part of the device according to the invention, or in general to adjust the maximum possible amplitude 165 of the movement of the button 162 on the wall 22, and thus adjust the maximum quantity or product delivered by the outlet 24 of the device according to the invention when the button 162 is pressed (and thus adjust different compression states of the bag 2 by the button 162).

[0812] The bearing surface 25 may be located at least partly on the button 162 and / or on the cap 70 (which may protrude from the button 162 or pass through the button 162) and / or on the support 166 (which may protrude from the button 162 or pass through the button 162).

[0813] The device according to the invention may include (between the button 162 and another part of the device, such as, for example, on a ring 158 surrounding the pouch 2 and in contact with the button 162) sensitive notches 167b and / or dosing notches 167a arranged to lock different screw positions of the button 162 onto the element 70 or 166 integral with the wall 22, and thus different compression states of the pouch 2 by the button 162. The ring 158 includes on its inner face grooves arranged to cooperate with at least one tab 159b of the button 162 and includes on its outer face recesses arranged to cooperate with at least one bump or ridge 159a attached to the side walls of button 162. The recesses indicate a dosage marked on one wall of the device, specifically on the bottom wall 21. The device is arranged so that between a minimum dosage position and a maximum dosage position, the rotation of the button is at least 360 degrees. In the maximum dosage position, the button is arranged so that it cannot be unscrewed; for example, a finger on the bottom wall will come into contact with the tab 159b. Referring to [Fig. 74], the support 166 is arranged to enter the bottom wall 21 on the side of the supply valve 4; the threaded hole 164 is inside the support.

[0814] With reference to [Fig. 76], it is noted that the indentations are not regularly positioned on the rim due to the non-linear deformation of the bag. It is noted that this device allows the chamber 2 to be purged in a button 162 position that provides a large displacement of the bag 2; this prevents the device from losing its prime and allows for the dispensing of small doses.

[0815] In a method according to the invention for all embodiments of devices according to the invention previously described:

[0816] - the reservoir 6 or product to be dispensed is filled, then once the reservoir 6 is filled or product, we close opening 87, then

[0820] This method of priming a device according to the invention is implemented by a system comprising:

[0821] - an enclosure arranged to house a device according to the invention in a initial position with the head facing upwards (i.e. preferably with the outlet located above (relative to Earth's gravity) at least part of the tank)

[0822] - means for evacuating the enclosure (preferably with a vacuum of at least 0.3 bar or even 0.5 bar relative to a pressure of one atmosphere) so that the air leaves the device according to the invention (for example, through its distribution valve); these vacuum means preferably comprise suction means, then

[0823] - means for tilting a device according to the invention located within the enclosure a new position by tilting it at least 30 degrees and preferably at least 90 degrees (preferably 180 degrees) from the vertical (relative to its initial position); these means for tilting typically include means for tilting the enclosure or a support located within the enclosure; and

[0824] -means for increasing the pressure in the enclosure (typically including means for introducing air into the enclosure through an air inlet).

[0825] With reference to Figures 77 and 78, for each of the embodiments of the device according to the invention, in particular those that can be implemented for a "spray" (for example, the embodiments of Figures 69 to 74), the supply valve 5 comprises: - a movable membrane 116, arranged to move between the open and closed positions of the valve 5, and - a connecting element 115, which carries the movable membrane of the valve 5, and which is held in the distribution channel connecting the outlet 24 to the inside of the bag 2. This distribution channel includes the housing 8. Preferably, the connecting element is held by clamping the internal walls of the distribution channel onto the connecting element.

[0826] The distribution channel 114 includes means 136 arranged to push the connecting element 115 against the internal walls of the distribution channel.

[0827] These means 136 typically include at least one element (such as teeth or walls) which emerges from the internal walls of the distribution channel and is inserted into a hollow 137 of the joining element so as to push, from the inside of the joining element, two parts of the joining element in two opposite directions but both directed towards at least one of the internal walls of the distribution channel.

[0828] The end of the membrane 116 (opposite to the end of the membrane 116 joining with the joining element 115) carries a nipple 117.

[0829] This nipple 117 is inserted into a part comprising a nozzle 59 and arms 132.

[0830] The nipple 117 and the nozzle 59 are arranged to leave at least one channel between them arranged to create a vortex of the fluid to be distributed.

[0831] The arms 132 are arranged to push the valve 5 into the channel 114 when the nozzle 59 is inserted into the channel 114.

[0832] With reference to figures 79 to 86 unless otherwise stated only the differences will be described in relation to device 101 of [Fig.3].

[0833] In this device 22000, the movable or deformable wall 22 is not in the reservoir; it is superimposed on the reservoir 6. The bottom wall 21 is substantially horizontal. The vertical and horizontal are not defined with respect to the direction of Earth's gravity. The terms vertical and horizontal are chosen by convention as two orthogonal directions. The wall 22 is preferably a deformable wall but can also be a movable wall.

[0834] The bottom piece 289 includes the bottom wall 21. The end piece 89 or the skirt 148 is arranged to fix the bottom wall to the tank. The bottom wall is horizontal or substantially horizontal, and the distribution conduit 114 is horizontal or substantially horizontal.

[0835] The device includes a cap 70, said cap being placed above the bottom wall 21. The cap 70 includes the deformable wall 22 and the bearing surface 25. The pocket 2 is delimited by the cap 70 and by the bottom piece 289.

[0836] The headgear 70 is made of a single piece:

[0837] - is formed of only one material, without discontinuity of that material, or,

[0838] - is formed of two or at least two materials and is a part made from of a bi-injection molding or overmolding of material(s) onto another material.

[0839] The cap 70 includes a skirt 149 extending vertically or substantially vertically from the support wall 25 or from the top of the cap 70. The base piece 289 includes a skirt 148 extending from the base wall 21 arranged to fix the base wall 21 to the reservoir 6 and to receive the cap 70. The base piece and base wall are fixed by interlocking, screwing, bonding, or welding. The skirt 149 of the cap 70 interlocks with the skirt 148 of the base piece 289.

[0840] With reference to Figures 79, 80, and 81, the base piece 289 includes at least one filling orifice or hole 87 opening into the interior of the reservoir (more precisely, located on the periphery of the base piece). The cap includes at least one plug 310 comprising the deformable wall 22 delimiting at least part of the internal volume of the pouch. Preferably, with reference to [Fig. 79], the base wall (21) includes two orifices 87. The skirt 148 and / or the return 361 is attached to the reservoir 6 by bonding or welding.

[0841] The tank 6 includes at least one layer of sealing material 352 such as PE or PP or an adhesive arranged to be welded or glued onto the skirt 148 of the bottom piece 289. Preferably the tank includes a layer 360 that is more rigid on the outside than the inner layer 352 such as cardboard or a cellulose material.

[0842] It is noted that the skirt may include a return or transverse wall 352 forming a stop when inserting (for the welding or gluing operation) the bottom piece 289 from inside the tank 6.

[0843] According to another aspect of the invention, a method is proposed for manufacturing a device comprising a fluid reservoir to be distributed, a part and a cap fitted with a stopper, comprising: - In the first stage of manufacturing the device, the bottom piece is glued or welded to the tank (the skirt 148 and / or the return 361) by inserting the bottom piece from inside the tank (the part of the tank without the bottom or the lower part of the tank). - In a second manufacturing step of the device, the reservoir 6 is closed by gluing or welding the lower part of the reservoir to the upper part fitted with the bottom piece. - In a third step, the tank is filled through the filling hole(s) 87, 87b - In a fourth step, at least one filling opening 87 of the base piece is plugged with at least one plug 310 of the cap 70.

[0844] The walls 118 of the tank are fixed between the skirt 148 and / or the return 361 and the cap 70.

[0845] Preferably, the outlet orifice 24 is elongated so as to take the form of a channel 189 inside a nozzle 30. This nozzle 30 is part of the cap 70. The orifice 24 is connected to the cap orifice 188, which is close to and preferably in contact with the skirt 148 of the base piece or the base piece 289. The channel 189 connects the distribution orifice 24 to the cap orifice 188 by passing through the skirt 149. The outlet orifice 24 passes through the skirt 149. The outlet 24 and / or the channel 189 is lateral.

[0846] The outlet port 24 is arranged so that the fluid exits in a lateral direction; channels 114 and 189 have substantially the same lateral direction.

[0847] The distribution conduit 114 connects the distribution port 355 to the outlet port 24. The distribution conduit 114 and the bottom wall 21 are formed in the bottom piece 289 and open onto a port 340.

[0848] The device 22000 includes a feed orifice 41 passing vertically through the bottom piece 289 (more precisely through the wall 21) and arranged to allow the fluid to pass into the pocket 2.

[0849] The device 22000 includes a distribution orifice 355 passing vertically through the bottom piece (more precisely through the wall 21) and arranged to allow fluid to exit from inside the pocket, preferably at least as far as the distribution conduit 114.

[0850] The distribution valve 5 which, in an open state, is arranged to allow fluid to exit from inside the bag 2 through the distribution orifice 355, and, in a closed state, is arranged not to allow fluid to exit from inside the bag 2 through the distribution orifice 355.

[0851] Preferably, valves 4 and 5 form a single piece by means of a connecting element 115.

[0852] The distribution valve 5 includes a distribution diaphragm 116.

[0853] The supply valve 4 includes a supply diaphragm 119.

[0854] In its closed state, the supply valve 4 (more precisely the diaphragm 119) blocks the orifice 41, and is pressed against the bottom piece 21. In the closed state of the valve 4, the diaphragm 119 extends according to the elongation of the conduit 114, that is to say horizontally or substantially horizontally.

[0855] In its open state, the supply valve 4 (more precisely the diaphragm 119) does not block the orifice 41, and is at least partially separated from the bottom piece 21 (more precisely separated from the seat 127) compared to its closed state.

[0856] In its closed state, the distribution valve 5 (more precisely the diaphragm 116) blocks the orifice 355, and is pressed against the bottom piece 21. In the closed state of the valve 5, the diaphragm 116 extends horizontally or substantially horizontally.

[0857] In its open state, the distribution valve 5 (more precisely the diaphragm 116) does not block the orifice 355, and is at least partially separated from the bottom piece 21 compared to its closed state.

[0858] The supply valve 4 is fixed to the wall of 21 by a connecting element 115. The distribution valve is fixed to the bottom wall by a connecting element 115. The inlet valves 4 and / or distribution valves 5 are independent and removable.

[0859] The inlet valve 4, more specifically the diaphragm 119, is not part of the cap (is not a part of the cap), is not manufactured or injected with the cap 70 or the base piece 289; there is no continuity of material from the inlet valve 4 with the cap 70 or the base piece 289. The distribution valve 5, or its seat, is not part of the cap, and is not manufactured or injected with the cap or the base piece 289; there is no continuity of material from the distribution valve 5 with the cap 70 or the base piece 289. The base wall is fixed; the base wall 21 is not movable relative to the skirt 148.

[0860] Device 22000 may further include: - (in the "atmospheric" version) a tube plunging into the

[0861] reservoir and forming a supply conduit (vertical or substantially vertical) arranged to conduct the fluid from the reservoir 6 to the supply valve 4; this tube may be part of the bottom piece 289 or be a separate piece; or - (in the "airless" version) a piston that rises inside the

[0862] reservoir 6 or a flexible pouch that collapses as fluid is extracted from reservoir 6.

[0863] The device includes means to facilitate priming, a first means as illustrated in figures 79 to 83 is a protective element 126 of the housing 134 of the bottom wall 21 more precisely in a periphery of the supply orifice 41 in order to protect the sensitive part 370 (periphery of the moving part of the valve 4).

[0864] An element 126 of the bottom wall 21 partially covers the valve 4 with respect to a direction 140 perpendicular to the bottom wall 21, preferably so that pressure on the surface 25 along this direction 140 cannot lift the valve 4 or limits the lifting of the valve 4 by an overpressure effect in the pocket 2 during the compression phase of the pocket 2.

[0865] In the housing 134 is inserted at least a part of the movable periphery 370 (370 indicates only the movable part of the membrane 119 during product pumping operations) of the feed membrane 119.

[0866] More precisely:

[0867] - two opposing movable lateral edges 371, 372 of the feed membrane 4, And

[0868] - a movable front rim 376 of the feed membrane 119, this movable rim 376 making the connection between the two movable lateral edges 371, 372, these edges being inserted at least in part into the housing 134.

[0869] The front movable rim 376 is further away from the joining element 115 than the movable rims 371 and 372.

[0870] Preferably at least 50% of the movable periphery (371, 372, 376) is housed in the housing 134 more precisely between the feed seat 127 and the element 126. It is noted that the periphery 370 is tapered so as to fit the feed seat 127. The feed membrane 119 includes a thickness which tapers towards at least a part (371, 372, 373) of the periphery of the feed membrane.

[0871] Another way to facilitate the priming of the device consists of a

[0872] bump 350 or bumps 350 on the periphery of the bottom wall, these bumps being discontinuous or not (for example, four bumps if the pocket is square). These bumps 350 are distributed around the periphery of the bottom wall 21 except at the center. With reference to [Fig. 80] representing the compressed state of the movable or deformable wall 22 (i.e., when the central part of the wall 22 is pressed against the bottom wall 21), at least one bump 350 is arranged to fit into the fold or deformation 190 formed at the periphery of the wall 22. Compared to a substantially flat bottom wall without bumps 350, the air remaining in the pocket 2 (in its compressed state) is reduced by at least 20% or even at least 40%. Preferably, the height of these bumps should be at least 1 mm, or at least 2 mm, extending outwards from the center of the base wall. The base wall should include one or more bumps arranged to reduce the air volume in the pouch during compression when the device is primed.

[0873] With reference to variant [Fig. 85], in this variant of the device 22000, the movable or deformable wall 22 is arranged to press directly or indirectly on the feed valve 4. More precisely, the movable or deformable wall 22 comprises at its periphery a part 53 or a pin 398 arranged (or rigid part) so as, when the support force 140 is applied to the support surface 25 from outside the bag 2, to transmit at least part of this support force 140 to the feed valve 4 directly or indirectly with or through a support member 139 (as shown in [Fig. 73a] and variant [Fig. 85], more precisely a pin or rigid part 198 and / or a tab 138) of the feed valve 4. (by pressing the supply valve 4 against its seat 127 by pressing on the diaphragm 119).

[0874] With reference to figures 72 and 85 where part 53 or pin 198 (or rigid part) of the bag 22 directly presses valve 4 more precisely on a bubble 135 of the membrane 119 of the supply valve 4 being arranged so that, by pressing on the supply valve 4, it closes valve 4 (by pressing the supply valve 4 against its seat 127 by pressing on the membrane 119).

[0875] Priming is thus facilitated by preventing air from passing through the orifice 41. The part 53 or the pin 198 (or rigid part) of the wall 22 or the support member 139 comes into contact with the valve 4.

[0876] The tongue 138 extends horizontally in the supply port 4L. The support member 139 of the supply valve 4 is integral with the bottom piece 289 (more precisely integral with the bottom wall 21) but not with the bearing surface 25. The member 139 belongs to the same part as the bottom piece 21. The member 139 comes from the molding of the bottom wall 21 and the channel 114, the pin 198 of the member 139 is preferably vertical, extending from the bottom piece, more precisely from the tongue 138.

[0877] With reference to Figures 84 and 85, the movable or deformable wall 22 is arranged to press directly or indirectly on the valve 5. More precisely, the movable or deformable wall 22 comprises at its periphery or in its center a part 153 or a pin 338 arranged so that, when the support force 140 is exerted on the support wall 25 from outside the pouch 2, which is partly delimited by a movable or deformable wall, it transmits at least part of this support force 140 to the valve 5, either directly onto the valve 5, more precisely onto the membrane 116, or as shown the [Fig.85] through a support member 339 of the valve 5 comprising a tab 338 and / or a pin 398 being arranged so that, by pressing on the valve 5, the valve 5 is opened, thus facilitating priming by helping air to pass through the orifice 355. The part 153 or the pin 398 of the wall 22 or the support member 339 comes into contact with the valve 5 pressing on the diaphragm 116, more precisely by moving the distribution valve 5 away from the bottom piece 289 (more precisely by moving it away from the bottom wall 21).

[0878] The support member 339 of the distribution valve 5 is integral with the bottom piece 289 (more precisely integral with the bottom wall 21 and comes from molding, with the pin which forms the channel 114).

[0879] During compression of the bag 2, the support member 339 of the distribution valve 5 is arranged to move after the support member 139 of the inlet valve arranged during an exercise of the support force 140 on the support wall 25 from outside the bag 2. The support member 139 of the inlet valve is arranged to move in the inlet port 41 and the support member 339 of the distribution valve is arranged to move in the distribution port 355.

[0880] It is noted that the wall 21 includes a tab 138 which extends (preferably horizontally) into the feed orifice 4L

[0881] The wall 21 includes a tab 338 which extends (preferably horizontally) into the distribution orifice 355.

[0882] With reference to [Fig.84] during full support from the resting state on the support surface 25 the support member of the distribution valve 5 supports after 70% of the compression of the bag 2 while the support member of the supply valve 4 supports the supply valve before 30% of the compression of the bag 2 or before 2mm of deformation of the top of the wall 22.

[0883] The support wall 25 includes, on the side of the pocket 2, a concave surface or part 254 of the movable or deformable wall 22, being surrounded by a flexible border 253 of the movable or deformable wall 22 and being surrounded by the support surface 25. The border 253 includes part 53 and / or part 153, these parts being preferably placed on a flexible part of the border 253 forming a flexible portion of at least 180 degrees, and even of 360 degrees around the support surface or the compression axis 290 (perpendicular to the bottom wall 21 around the center of the bottom wall).

[0884] Part 254 of the wall 22 forms a junction line 293 of the wall 22 with the edge 253 (preferably forming a circle). This junction line 293 of the wall 22 is not supported by the wall 21. The edge 253 is cantilevered and rests on the periphery of the bottom wall 21 and / or on the skirt 148 (towards the peripheral edge of the pocket 2), forming a support line 292 of the flexible edge 253. The edge flexible 253 is included between the junction line 293 and the support line 292 having a width of at least 3 mm and even a width of at least 4 mm or even at least 5 mm (measured in a plane perpendicular to the axis 140).

[0885] During a support 140 on the support surface, the flexible border 253 surrounding the support surface or surrounding the part 254 deforms towards the bottom wall at the junction line 293, preferably the entire junction line 293 moves preferably substantially parallel towards the bottom wall 21 (or moves at an angle of less than 20 degrees with respect to the bottom wall 21) preferably at the beginning of the compression of the pocket 2, before 10% (from the initial volume of the pocket 2) of the compression of the pocket 2, or at least before 30% (from the initial volume of the pocket 2) of the compression of the pocket 2, or even at least before 50% (from the initial volume of the pocket 2) of the compression of the pocket 2 (along the compression axis 290 at the center of the pocket 2).The flexible border 253 comprising part 53 and / or 153 deforms (at least at part 53 and / or part 153) by at least 0.1 mm or even 0.3 mm towards the bottom wall before 10% (from the initial volume of pocket 2) of the compression of pocket 2, or at least before 30% (from the initial volume of pocket 2) of the compression of pocket 2, or even at least before 50% (from the initial volume of pocket 2) of the compression of pocket 2 (along the compression axis 290 at the center of pocket 2). Preferably the entire border 253 moves at least 0.2 mm and even at least 0.4 mm (and even at least 0.8 mm if the border 253 includes a flexible material) towards the bottom wall before 30% of the compression of the pocket 2 at its junction line 293.

[0886] It is noted that the pawls 198 and 398, being respectively attached to part 53 and part 153, move towards the back wall by the same distance as parts 53 and 153 respectively.

[0887] With reference to [Fig.85] and 86, the device includes two support means 53 and 153, when applying pressure from the rest state of the device, it is preferable that the pressure on the inlet valve 4 by part 53 (directly or indirectly) starts before the pressure on the distribution valve 5 by part 153 (directly or indirectly), the pressure on the inlet valve 4 by part 53 is made before 30% (from the initial volume of the bag 2) of the compression of the bag 2, and the pressure on the distribution valve is made after 50% (from the initial volume of the bag 2) of the compression of the bag 2.

[0888] The edge 253 is preferably substantially flat, parallel to the bottom wall or forming an angle of less than 20 degrees with the bottom wall. The support wall or bearing surface 25 includes the deformable or movable wall 22. The surface 253 may include a flat portion and / or include at least one or more hollows and / or bumps to create a more flexible (and deformable) area to allow for greater travel towards valve 4 and / or 5 and have a greater displacement. Part 53 and 253 is less thick than part 254 on average or part 253 is made of a more flexible material than part 254, more flexible at least than part of the bearing surface 25, and preferably more flexible than the top of pocket 2.

[0889] With reference to [Fig.85a] in one variant the movable or deformable wall 22 is arranged to press directly or indirectly on the supply valve 4 comprising a flexible part 435 obtained preferably by overmolding or bi-injection (or in the same material as the flexible border 253 in the case where it is made of elastomer), this flexible part 435 integral with the flexible border 253 is in the pocket 2 is oriented towards the bottom wall. The flexible part 435 is identical with the valve 4 and is not mobile relative to the wall 22. The part 435 is arranged so that when the support force 140 is exerted on the support surface 25 from outside the bag (2), it transmits at least part of this support force 140 to the flexible part 435 by pressing on the bottom wall or a part attached to the bottom wall to block or close the feeding orifice.The support part 53 or rigid part 198 comprising the flexible part 435 and forming the valve 4. .

[0890] Part 53, part 153, pins 198, pins 398, flexible part 435 (valve 4) all these parts are integral with the rim 253. The rim 253 is arranged so that when the support force 140 is exerted on the support surface 25 from outside the bag 2 (delimited in part by a movable or deformable wall), it transmits at least in part this support force 140 to the supply valve 4 to press the valve 4 against the bottom wall and / or transmits at least in part this support force 140 to the distribution valve (5) by pressing on the distribution valve to detach the distribution valve from the bottom wall 21, more precisely to detach the membrane 116 of the distribution valve 5 from the distribution seat of the valve 5 formed on the bottom wall 21.

[0891] All aspects of the different variants facilitating priming can be combined in particular, the bump 350, the protective element 126, the supports on the intake valves 4 and / or distribution 5.

[0892] In the variants of figures 84 and 86 of the device 22000 does not include plugs 310 and the cap 70 can rotate relative to the bottom piece 289, it can rotate 360 ​​degrees in the variant of [Fig.85] but not completely for the variant of [Fig.84] because of the pin 198 which interferes with the bottom wall in this case a bean-shaped opening in the bottom wall 21 is provided allowing rotation.

[0893] The cap 70 is arranged to rotate about the bottom piece 289 (preferably about a vertical axis perpendicular to the wall 21, this axis preferably passing through the center of the wall 21) between the open position and a position The closure of the cap 70, whereby the cap 70 (more precisely the skirt 149) blocks fluid from exiting the distribution orifice 355 to the outside of the device. The cap 70 is arranged to block or stop the distribution from the bag 2 (up to the point of filling the channel 114). In the closed position, the orifice 340 is covered by the skirt 149, and in the open position, the orifice 340 is uncovered and communicates with the orifice 188, opening the passage from the channel 114 to the channel 189.

[0894] The bottom piece 289 or the bottom wall 21 is clipped onto the neck 85 and can rotate relative to the reservoir 6, so that it can be oriented by a user. Thus, to perform the sealing, either the bottom piece 289 is held by a portion 195 and the cap 70 is rotated, or the cap 70 is held and the bottom piece 21 is rotated with the portion 195. The channels 114 and 189 can rotate about the same axis and communicate when they are more or less opposite each other. An orifice 188 in the cap 70 communicates with an orifice 340 in the bottom piece.

[0895] Visual markers 365, 366 allow visual distinction, from outside the device, between the open and closed positions of the cap 70. The skirt 148 includes the part 195 of the bottom piece 89 visible from outside the device. Being longer than the skirt 149, this visible part 195 does not go around the wall 21 and includes the notches or visual markers 366, while the skirt 149 includes the notches or visual markers 365.

[0896] In this closed position the distribution conduit 114 does not open onto the outlet port 24 or the port 188 so that the cap 70 (more precisely the skirt 149) blocks the distribution conduit 114.

[0897] With reference to [Fig.82], the device 22000 comprises two sealing lines 341 and 342 on either side of the orifice 340, more specifically recessed lines and / or raised lines at the level of the skirts 148 and 149. In an unshown variant, the sealing line 341 comprises one or two sealing skirts of the cap 70 arranged to rotate in grooves in the bottom wall 21.

[0898] In all embodiments the reservoir may include external walls of cardboard (more generally of cellulose) and internal walls or film of plastic.

[0899] It is noted that in all the embodiments described above, the device is arranged to operate (i.e. to distribute fluid through the outlet via the supply and / or distribution valves) with its distribution head facing upwards (i.e. outlet 24 located above the tank 6) or downwards (i.e. outlet 24 located below the tank 6).
