[Modes for carrying out the invention]

[0075] The present invention is not limited to these embodiments, and in particular, variations of the present invention having only one feature selected from the features described or illustrated below and isolated from the other features (even if the selected feature is isolated in a sentence containing the other features) can be considered part of the present invention if the selected feature is sufficient to discuss a technical advantage or to distinguish the present invention from the prior art. This selection can be considered to have at least one preferred functional feature if, without structural details and / or with only a portion of structural details, or even just a portion thereof, is sufficient to discuss a technical advantage or to distinguish the present invention from the prior art. Preferably, the product to be distributed is a fluid.

[0076] First, with reference to Figures 1 to 3, a first embodiment of the device 101 according to the present invention for distributing fluid will be described.

[0077] Unless otherwise specified, and in cases purely illustrative, - 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 may be a multilayer film made of various materials, or preferably a polyolefin-based material.

[0078] The fluid includes liquids and / or gases, and is preferably a liquid, cream, paste, gel, or a mixture thereof. The fluid distribution device 101 comprises a pocket 2 having an internal volume configured to contain the fluid, the internal volume of which is at least partially defined by a deformable wall 22. The deformable wall is optional. Generally speaking, we are talking about a movable wall 22, since it becomes a deformable pocket whether it is a deformable wall or a rigid wall with relative motion such as a piston.

[0079] Pocket 2 is formed by a bottom wall 21 (also called pocket wall 21) and a flexible, deformable wall 22. The pocket wall 21 and the deformable wall 22 face each other. The deformable wall 22 has a concave shape toward the bottom wall 21. The deformable wall 22 is fixed or welded to the bottom wall 21. The bottom wall 21 is a rigid wall and is more rigid than wall 22.

[0080] Walls 21 and 22 are made of, for example, polypropylene or polyethylene. Device 101 includes a distribution component 23 with a distribution cavity 8. Pocket 2 is connected to the distribution cavity 8. The device 101 is equipped with a pressing surface 25, which is configured to reduce the internal volume of the pocket 2 by deforming a deformable wall 22 under the action of pressure.

[0081] Device 101 is equipped with an exit 24. Exit 24 connects to the outside of device 101. The outlet 24 is preferably located in the distribution component 23.

[0082] Device 101 includes a distribution opening 18 or 355 that connects the pocket 2 to the distribution cavity 8. The device 101 includes a distribution valve 5 located within a distribution cavity 8. When open, it allows fluid to pass from inside the pocket 2 through the distribution opening 18 and through the distribution cavity 8 toward the outlet 24. When closed, it does not allow fluid to pass from inside the pocket 2 toward the outlet through the distribution cavity 8.

[0083] The pressing surface 25 is configured to reduce the internal volume of the pocket 2 by deforming the deformable wall 22 under the action of pressure, or more precisely by crushing it in the direction of the pocket wall 21. The distribution component 23 is configured to move in at least translational motion when pressure is applied to the pressing surface 25.

[0084] The deformable wall 22 has shape memory. When the wall 22 is not subject to any external constraints, the wall 22 returns to or maintains a shape that maximizes the volume of the pocket 2 (preferably concave).

[0085] Device 101 is equipped with a supply opening 41 connected to a fluid reservoir 6. The reservoir 6 is at least partially defined by a flexible wall 108 or flexible bag 14, which is typically a multilayer film. Device 101 includes a supply opening 41 that connects the reservoir 6 to the internal volume of pocket 2. The opening 41 coincides with the opening 124 of the reservoir 6 that connects the reservoir 6 to pocket 2.

[0086] Device 101 includes a supply valve 4, which, when open, allows fluid to pass from the reservoir 6 through the supply opening 41 into the pocket 2, and when closed, does not allow fluid to pass through the supply opening 41 into the pocket 2.

[0087] The supply valve 4 is located inside the pocket 2. - When closed, press the supply opening 41, - When in the open state, it is configured to be spaced apart from the supply opening 41.

[0088] The supply valve 4 (movable between closed and open positions) is, in the closed position, pressed against and held in place by a stationary portion of the inner wall of the pocket 2 (at least partially surrounding the associated supply opening 41 and referred to as the supply seat) that is "rigid" (i.e., not made of flexible material). More precisely, the supply valve 4 is equipped with a membrane that is pressed against the supply seat when the supply valve 4 is closed and moves away from this supply seat when it is open. The supply seat is located inside pocket 2, above the pocket wall 21.

[0089] When stationary, that is, when device 101 is not subjected to stress or external force, valve 5 is in the closed position. Preferably, even if it is not so important, the valve 4 is also closed when stationary, i.e., when the device 101 is not subjected to stress or external force.

[0090] When pocket 2 is filled with the fluid to which it is distributed, and the volume of pocket 2 decreases (for example, with an increase in pressure on the pressing surface 25), - The distribution valve 5 separates from the distribution seat 13, the valve 5 opens, the fluid exits through the outlet 24, and the pocket 2 becomes empty, at least partially. - The supply valve 4 is pressed against the supply opening 41, and the valve 4 is in the closed position, so the liquid cannot (or can barely) escape from the pocket 2 to the reservoir 6.

[0091] When pocket 2 is filled with the fluid to which it is distributed, and the volume of pocket 2 increases (for example, by the release of pressure on the pressing surface 25), - The distribution valve 5 presses against the distribution seat 105, the valve 5 closes, and the liquid cannot flow out of the pocket 2 to the outlet 24. - The supply valve 4 is "sucked in" and moves away from the supply opening 41, the valve 4 opens, and the fluid can flow from the conduit 6 into the pocket 2 and fill the pocket 2. The distribution channel connects the outlet 24 to the inside of pocket 2. This distribution channel is equipped with a cavity 8.

[0092] The bottom wall 21 is integrated with the end piece 89, also known as the "eye" 89. The device 101 includes a reservoir 6 defined by walls 14, 108 fixed to the end piece 89, or more precisely by flexible bags 14, 108 welded to the end piece 89.

[0093] Pocket 2 is located inside either Reservoir 6 or Bag 14. The outlet 24 is configured to distribute the fluid in a direction substantially parallel to the pressing surface 25.

[0094] The plug 77 that blocks outlet 24 is configured to move between the following two positions (closed position and open position). - Closed position, this is the position in which the part 771 (stud) of the plug 77 is inserted into the outlet 24 to block or protect the outlet 24 from contamination, and the distance from the closed position of the distribution valve 5 to the outlet 24 is less than 6 mm, and even less than 4 mm. The groove on the inner circumference of the outlet 24 allows the part 771 (stud) of the plug 77 (or any valve or plug 77 in general) to block or protect the outlet 24 from contamination, preventing the passage of the fluid to be distributed (liquid, cream, or gel) but leaving an air passage through the outlet 24. - Open position (shown in Figure 1), this is the position where part 771 of plug 77 is not inserted into outlet 24.

[0095] Pocket 2 is located inside reservoir 6. Device 101 includes a supply valve 4, which, when open, allows fluid to pass from the supply conduit through the supply opening 41 into the pocket 2, and when closed, does not allow fluid to pass from the supply conduit through the supply opening into the pocket 2.

[0096] The supply valve 4 is integrated with the distribution valve 5. The supply valve 4 and the distribution valve 5 are single components made from a single material. Component 23 and pocket wall 21 are a single, identical component with no discontinuities in material.

[0097] The end piece 89 and part 23 are a single, identical part with no discontinuities in material. There are one or two filling holes 87 and 87b, each opening to the inside of the reservoir 6. Preferably, there are two of these filling holes, located on either side of the outlet 24. These filling holes penetrate the end piece 89.

[0098] A single plug 310 can, at the same time, - Block the filling hole, - It is configured to block and / or protect the exit 24. Plug 310 is equipped with a plug 77 that is removable by a hinge.

[0099] The plug 310 is equipped with two cylindrical pins 313 that, at the positions of the filling holes 87, 87b, are slightly tightened (preferably with a snap) and fitted into the end piece 89 in order to adjust and hold the plug 310 precisely during assembly. This is the primary means of securing the plug 310 to the end piece 89, allowing the assembled fixture to be maintained by complementary, independent clips. The diameter of the pins 313 is preferably greater than 3 mm, and even greater than 4 mm. The two holes 87, 87b are preferably open, but in versions not shown, one of the holes 87 or 87b is not open, and this unopened hole is referred to as the adjustment hole or positioning hole.

[0100] The end piece 89 has two lateral notches 130 configured to hold the device during filling and / or closing by mating the plug 310 into the end piece 89. Typically, the end piece 89 is configured to slide within the rail of the device for conditioning. The notches are located at the lateral end of the end piece 89 toward the lateral end of the reservoir 14. The plug 310 has a cavity 312 configured to receive the end of a distributor component 23, which has an outlet 24. The distributor component 23 passes through the plug 310.

[0101] In these variations, the plug 310 includes an applicator 208 formed within the plug with (at least partially) a dome shape 308 or a beak shape 309. The cavity 312 is configured within the applicator 208 to receive or mate with the distribution component 23. The cavity 312 at least partially surrounds the distribution valve 5 and / or the distribution cavity 8.

[0102] The bag 14 is welded to the eye 89, more precisely on the fin. In another modification, the eye has a welded wall that extends along the axis of the distribution channel 114, and the cavity formed between the welded wall and the distribution component 23 is concealed by a plug 310.

[0103] Referring to Figure 3a, the applicator 208 has a dome shape 308 with a thickness of at least 4 mm, and moreover, at least 8 mm, which spreads the distributed product or fluid and / or allows a part of the body to be massaged with the product or fluid. A removable cover (not shown) may protect the applicator 208. The applicator may have a layer 315 at the location of the outlet 24 or opening 24, which may be a metal layer, a foam layer or other fabric layer. If the layer 315 is made of, for example, foam or fabric, it covers the opening 24. The device may have several openings 24. At least one opening 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 pin 313, applicator 208 (without layer 315) and cavity 312 are manufactured as a single part by injection molding PE (polyethylene) or PP (polypropylene).

[0104] Referring to Figure 3b, the applicator 208 of the plug 310 forms a spout 309 configured to precisely distribute the product. The end of the spout carries a pad 316, which can be made of foam or fiber for distributing, for example, gloss or lipstick. The outlet 24 is at the end of a rod within the pad 316. Several small holes may be made in this rod to homogenize the distribution or product on the pad. In a version without the pad 316, the outlet 24 is located at the end of the spout 309. The distributing component does not pass through the plug. The plug 310 further includes a plug 77 for closing the outlet 24, which is removable by a flexible link means connected to the base of the spout 309. The pin 313, applicator 208 (without pad), cavity 312, plug 77, and flexible link are manufactured as a single piece by injection molding PE (polyethylene) or PP (polypropylene).

[0105] The device according to the present invention may include an air pocket, which may include an extraction hole 11 configured to extract air from the pocket. The extraction hole is located at a distance of less than 3 cm from at least one of the filling holes so that when the device is placed under vacuum, the distributed fluid does not escape through the filling holes.

[0106] The wall 22 is provided with a skirt 155 that, in the same measurement direction, is at least the same height as the height of the entrance to the cavity 8 on the pocket 2 side (i.e., at least 2 mm or 3 mm in height). The skirt 155 allows the valve 5 to be inserted into the cavity 8 from the inside of the pocket 2, perpendicular or substantially perpendicular to the direction in which the height of the skirt 155 is measured.

[0107] The end piece 89 is recessed into the plug 310. The distribution surface 207 is formed by the plug 310 and the end piece 89. The cavity 312 has a plug 310 between the pins 313.

[0108] Figures 3c and 3d illustrate another modification of device 101, and only the differences from the modifications in Figures 2 and 3 are described.

[0109] In this modified example, the end piece 89 is composed of the following three parts: - Outer crown, - The central part (which is also part of the distribution part 23), which has an outlet 24, - Connecting wall 9, which has at least one (preferably at least two, typically three) and connects the outer crown of end piece 89 to the central portion of end piece 89. These connecting walls 9 are configured to leave at least one empty space 15 between the outer crown of the end piece 89 and the central portion of the end piece 89, which is configured to allow the passage of a filling pipe 46 through this empty space 15 into the interior of the reservoir 6 (typically along the outside of the pocket 2).

[0110] Therefore, it should be noted that pocket 2 does not have a rotationally symmetrical form around the longitudinal axis of device 101 that allows pipe 46 to pass through.

[0111] Accordingly, the method according to the present invention typically comprises a reservoir 6 filling step by a filling pipe 46 that enters into the reservoir 6 (usually along the outside of the pocket 22) through this at least one empty space 15 while the plug 310 is removed from the rest of the device 101, and the reservoir 6 filling step is performed by fluid coming from outside the device 101 flowing into the reservoir 6 through the pipe 46.

[0112] After filling, the plug 310 can be reassembled onto the neck 85. For this reason, the neck 85 has a male thread 16, but if it had a female thread, the end piece 89 and outlet 24 would be pushed inward into the device 101, reducing compactness, so this male thread is advantageous compared to a female thread.

[0113] Neck 85 is integrated with the wall of Reservoir 6 (it's an extension of the wall). Also note that this space 15, which allows the passage of the pipe 46 for filling the reservoir 6, is also shown in Figure 3.

[0114] Figures 4 through 33 show second embodiments of the six devices 102, 103, 104, 105, 106, and 107. Unless otherwise specified, only the differences from device 101 in Figure 1 will be described in more detail.

[0115] Each of embodiments 102, 104, 105, 106, and 107 of the device for distributing fluids comprises the following: - Exit 24, - Pocket 2, which has an internal volume for containing fluid, the internal volume of this pocket 2 is at least partially defined by the movable wall 22. - Reservoir 6, which is configured to contain fluid, has two openings, one facing pocket 2 at the upper opening 124 and the other at the lower opening 87, and is configured so that the internal volume of reservoir 6 decreases when the fluid flows out of the reservoir. - Distribution valve 5, which, when open, allows fluid to pass from pocket 2 to outlet 24, and when closed, does not allow it. - The supply valve 4, when open, allows the fluid contained in the reservoir 6 to pass into the pocket 2, and when closed, does not allow it.

[0116] The lower opening 87 is configured to allow the passage of fluid, preferably a cannula (or filling pipe) that transports the fluid, and to fill the reservoir 6 with fluid at least partially up to the supply valve 4. The fluid comes into contact with the supply valve 4, and preferably the internal volume of the pocket 2 is also filled with at least a portion of the fluid. The supply valve is configured, for example, by bending, to allow the passage of a pipe or cannula.

[0117] Referring to Figure 4, the distribution component 23 (also called the distribution head 23) includes the following: - Cap 70, and - Optional insert 71.

[0118] Note that the deformable wall 22 cannot move within the cap 70. The cap 70 does not have any movable pocket components. The cap 70 is mounted on top of the flexible wall 22. The wall 22 is the base of a bellows or dome. The dome has an upper end 228 connected to the cap 70 by material continuity, overmolding, or bi-injection molding, and a lower end 229 connected to the wall 118 of the reservoir 6 by material continuity, overmolding, or bi-injection molding. The joints and / or connections with the ends 229 and 228 are sealed.

[0119] The deformable wall 22 is attached to the wall 118 of the reservoir 6. The distribution component 23 is equipped with a cap 70. The pressing surface 25 forms part of the distribution component 23. Cavity 8 is located inside cap 70. The cap 70 is mounted on top of the deformable wall 22.

[0120] The deformable wall 22 and cap 70 are - The materials are grouped together into a single part of the same material without interruption, or - They are manufactured as the same part by overmolding or bi-injection molding.

[0121] The distribution valve 5 is located within a cavity inside at least one part 70 (of the distribution component 23) that has continuity of material with the wall 22, and this cavity is lateral and located between the pocket 22 and the outlet 24. The connection between the cap 70 and the insert is sealed to have an air or gas pocket 38.

[0122] The reservoir 6, configured to contain fluid, has two openings, the upper opening 124 facing the pocket 2 and the other being the lower opening 87. The reservoir 6 is configured such that, once the device is started (primed), the internal volume decreases as fluid flows out of the reservoir while pressure is applied to the wall 25; this process will later be referred to as the pumping operation.

[0123] The reservoir 6 has a rigid wall 99 within which the piston 86 slides. The piston 86 is located between the reservoir 6 and the bottom wall 91. After the reservoir 6 is filled through the opening 87, the piston 86 is inserted into the opening 87, forming the plug 310. The reservoir 6 has a cylindrical shape and an elongated shape.

[0124] The reservoir 6 is provided with a side wall 118 or container 118 between the bottom wall 91 and the pocket wall 21. The side wall 118 is part of component 10, and component 10 is - Houses piston 86, - Tighten and hold the pocket wall 21, - The wall 22 is formed at the joint 229 under the continuity of the same material or two different materials by bi-injection molding.

[0125] The deformable walls 22 and 10 are - The materials are grouped together into a single part of the same material without interruption, or - Manufactured as the same part by overmolding or bi-injection molding.

[0126] At least one hole 95 in the piston 86, or between the piston and the wall 99, allows air to be drawn out of the reservoir 6 when a portion (more precisely, the upper part) of the piston 86 is inserted into the reservoir. Thus, the piston 86 has two lips, of which the first upper lip 88 (facing 124) is configured to enter the reservoir in an unsealed manner with at least one hole 95, and the second lower lip 28 (facing the bottom 91) is configured to enter the reservoir 6 in a sealed manner. Note that the piston 86 is a single piece and does not have a valve.

[0127] To reduce air, the piston is preferably provided with a dome-shaped wall 26. The dome shape 26 reduces the air between the piston and the product, and when the piston is inserted into the reservoir, it is possible to push the cream or product being distributed against the side of the wall 99. Unless the lower lip 28 of the piston is fitted against the inner wall 99 of the reservoir 6, the air contained in the reservoir can escape from the device.

[0128] At least one hole 95 is configured to allow fluid to pass between the sealing zone 97 between the piston 86 and the wall 99 and the reservoir 6. Typically, there are several holes 95. The openings 95 may also be slots around the upper lip 88.

[0129] Referring to Figures 5 to 10, the reservoir 6 is at least partially defined by a movable piston 86 configured to move in such a way as fluid flows out of the reservoir 6 that the internal volume of the reservoir 6 decreases, the piston 86 having a lower opening 87 which is closed by a removable plug 310.

[0130] The removable plug 310 is screwed into piston 86. The piston 86 is located between the reservoir 6 and the bottom wall 91, and the preferably rigid bottom wall 91 is provided with means 93 for preventing the rotation of the piston 86 while the plug 310 is screwed onto the piston 86 when the piston 86 is in contact with the bottom wall 91. The bottom wall 91 is provided with fixing means 45 for fitting together with the rigid wall 118 of the reservoir, preferably by snapping them together.

[0131] Different variations of this embodiment may be combined with each other. - In the modified example shown in Figure 6, means 93 is typically, for example, a slot into which a portion of the piston 86 is inserted, and / or - In the modified example shown in Figure 7, means 93 is typically, for example, a clipping means and / or - The piston may be curved (disk, ellipse, or other) or polygonal. In the modified example shown in Figure 10, the piston 86 has a polygonal shape including several sides connected at an angle in a cross-sectional view perpendicular to the direction of displacement of the piston 86 along the wall 99, and the device further includes force distribution components 33 configured to press the piston 86 against the wall 99 on some (preferably all) sides of the polygon, except for the corners of the polygon. In another modified example, the distribution components 33 can be replaced with a variable thickness of the wall of the piston 86.

[0132] Figures 11 and 12 show one embodiment of the device 104 for distributing fluid. Only the differences from the device 103 in Figures 5 to 10 will be explained.

[0133] Referring to Figures 11 and 12, the piston 86 is not perforated and does not have a filling opening, and the filling opening 87 is formed by the lower end of the wall 118 (more precisely, the opening 87 is cylindrical).

[0134] After the reservoir is filled, the piston 86 is positioned therein, more precisely by sliding within the cylinders 87 and 118, preferably during this process the bottom wall 91 is fixed to the piston. The lower lip 28 is attached to the bottom wall 91 by the elastic means 32 at least before being introduced into the opening 87.

[0135] During introduction into the opening 87, the lip 28 equipped with the elastic means 32 deforms, and this deformation has the effect of displacing the elastic means 32 toward the axis of the piston. This displacement has the effect of separating the elastic means 32 from the bottom wall 91. To emphasize this deformation, it is advantageous to add localized excess material, such as a ring material 29, to the inner wall 99 of the reservoir 6. The elastic means 32 is configured to easily detach from the bottom 91 during the first pumping operation (before the first 10 pumping operations), i.e., when the device is started once and the wall 22 is compressed.

[0136] The protruding wall 31 of the bottom 91 is configured to engage with the elastic means 32, causing the piston 86 to rise relative to the bottom wall 91. At least a portion of the protruding wall 31 is introduced between the elastic means 32 and the lip 28. The elastic means 32 can be clipped to the protruding wall 31.

[0137] Figures 12a and 12b show a part of a second embodiment of the device 104 according to the present invention, by modifying the piston 86. Only the differences from the description of Figures 11 and 12 will be explained regarding this modification.

[0138] The Piston 86 has a lip. The upper parts 88 (or "upper lips") of these lips are the first to enter the reservoir 6 when the piston 86 is inserted through the opening 87. The lower lip 96 (or "lower lip") of these lips enters the reservoir 6 second (or last) as the piston 86 is inserted through the opening 87.

[0139] The upper lip 88 is provided with a relief, rib, or stud 197 that separates the upper lip 88 from the inner wall 118, thereby allowing air or the product being distributed to pass between the relief, rib, or stud 197 and escape from the reservoir 6 through the opening 87 when the piston 86 is inserted through the opening 87.

[0140] Once these lower lips 96 enter the wall 118 through the opening 87, the lower lips 96 are configured to seal the opening 87 located between the inside of the reservoir 6 and the outside of the device.

[0141] When the piston 86 is inserted through the opening 87, the inner side opening 94 of the piston 86 allows air to escape, preventing air bubbles from forming inside the piston 86.

[0142] The piston 86 is provided with means 98 for holding the piston 86 against the wall 91. There is no outer wall by part 91 surrounding the outside of the piston, even partially. To improve piston retention, the wall (not shown) of part 91 may be fitted inside the piston 86. These retention means 98 typically include the following: - A rod or other means integrated with the piston 86, which is fitted, clipped, or attached to the wall 91, or - Receiving means integrated with the wall 91 for fitting, clipping or attaching a rod or other means, The piston 26 and the wall 91 are a single unit while the piston 86 is inserted into the opening 87, and the piston 26 and the wall 91 are configured to separate by mechanical action as the piston 86 moves forward within the wall 118 of the reservoir 6 (the wall 91 remains fixed) and / or when the device is closed.

[0143] Figures 13 to 22 show another embodiment of the device 105 for distributing fluid. Only the differences from the device 104 in Figures 11 to 12 will be described. The wall 108 is flexible or mainly comprises a flexible wall (hereinafter referred to as "flexible wall 108" or "wall 108").

[0144] The reservoir 6 configured to contain a fluid - comprises a flexible wall 108 with two openings, an upper opening 124 facing the pocket 2 and a lower opening 87, and - is defined by a bottom wall 91, 310, preferably removable and configured to close the lower opening 87. The plug 310 is integrated with the wall 91. The flexible wall may be formed, for example, by injection molding or thermoforming.

[0145] The cross-sectional area of the upper opening 124 (this cross-section is selected to minimize the area of the upper opening 124) is at least 6 times (even at least 8 times) smaller than the cross-sectional area of the lower opening 87 (this cross-section is selected to minimize the area of the lower opening 87).

[0146] The flexible wall 108 is configured to deform to reduce the internal volume of the reservoir 6 when the fluid exits the reservoir 6. The edge 43 and / or the skirt 42 are configured to seal between the inside of the reservoir and the outside of the device.

[0147] The device 105, more precisely the rigid wall 91, is configured to fix and hold the position of the lower opening 87 of the device 105 relative to the position of the upper opening 124 of the device 105.

[0148] The flexible wall 108 is fixed to the pocket 2 by an airtight connection. The flexible wall 108 has a cylinder 81 at the upper part of the reservoir 6, which enables sealing. To provide airtightness, this cylinder 81 is compressed (in the case of FIGS. 14 and 16) or is in a nested state (in the case of FIG. 13). It is preferable to provide a second cylinder concentric with the first cylinder 81.

[0149] Device 105 includes a means 110 (optional) for guiding the cap 70 (a component that forms the internal volume of pocket 2 and further houses the distribution valve 5) internally. The means 110 is configured to guide the movement of the cap. The means 110 takes the form of a wall 110 that emerges from the bottom wall 21.

[0150] Different variations of this embodiment 105 can be combined with one another: - The flexible wall 108 is joined to the pocket 2 by the following airtight coupling: o By welding, and / or, o As shown in the modified example in Figure 13, by clip fastening (by clip 83) and / or by interlocking, and / or o One component located outside the reservoir 6 and forming or integrating with the pocket 2 is joined to the other ring 109 inserted inside the reservoir 6 (as described above, its upper edge forming the supply seat 62) by compressing the flexible wall 108 around its upper opening 124, as shown in the modified examples in Figures 14, 16, and 18. In the modified example in Figure 14, the ring 109 is integrated with the rigid wall 91, and the ring 109 and wall 91 form the same component with material continuity, while in the modified examples in Figures 16 and 18, the ring 109 and wall 91 form two separate components with material continuity and / or - The flexible wall 108 and the supply valve 4 may be formed in the same part with material continuity (as shown in Figures 16 to 18), or they may be formed in two separate parts with material continuity (as shown in Figures 13 to 15).

[0151] Referring to Figures 19 to 22, the device 105 has a "flat shape". To reduce the amount of air trapped during closure, the retaining element 17 allows the side wall of the reservoir to be held but does not seal it. In fact, sealing is achieved by axial crushing rather than lateral crushing. If the reservoir is injection molded as a flexible material, additional sealing is not necessary, but if the reservoir is thermoformed, it is preferable to add a gasket 39 if the precision of the injection parts 93 and 122 is insufficient. The gasket 39 has at least one flexible surface that contacts the wall 108 so as to seal between the reservoir 6 and the outside.

[0152] In the case of the flexible wall 108 obtained by thermoforming, a raw material (typically a sheet or film) thicker than the reservoir thickness is deformed to typically improve the thickness to about 0.2 mm, in which case a "thick portion" (e.g., 1.5 or 2 times thicker) is formed, and then this "thick portion" is partially cut, from which the pocket 108 is created.

[0153] It should be noted that the bottom wall 21 is provided with a ring 48 at the opening 124, which is preferably deformed by ultrasonic waves (in the direction opposite to the center of the hole 41) and configured to compress the reservoir wall 108.

[0154] Figures 23 to 29 show another embodiment of the device 106 for distributing fluid according to the second embodiment. Only the differences from the device 105 in Figures 13 to 22 will be described. Referring to Figure 23, the wall 91 is screwed to the neck 87 of the reservoir 6.

[0155] The lower opening 87 takes the form of a neck as referred to in 85 or 87. This neck 87 of the reservoir 6 forms an inlet opening for filling the reservoir 6 when this neck is not screwed to the wall 91.

[0156] The wall 91 thus forms a plug for the neck 87. The wall 91 preferably integrates a plug 310 configured to screw into the neck 87 and a fastening means 45 configured to fit integrally with the wall 12, preferably by snap fastening, both preferably from the same material.

[0157] Wall 91 is connected to side wall 12, and when the neck of side wall 12 is screwed to wall 91, - Hide reservoir 6, - It is configured to hold reservoir 6.

[0158] Wall 12 surrounds Wall 108, which defines the internal volume of Reservoir 6 (defining at least 50%, and moreover, at least 75%, of Reservoir 6).

[0159] These side walls 12 are interlocked with or snap-fastened with the wall 91. The wall 91 is equipped with snap-fastening means 45. The reservoir is blow-molded from PE (polyethylene) or PP (polypropylene). The reservoir 6 includes a bump 60 configured to be welded to the bottom wall 21. Walls 12 and 21 form a container 122 configured to house the reservoir 6.

[0160] The side wall 12 is part of component 100 or wall 100, and component 100 or wall 100 is - Including a flexible wall 108, - To keep the pocket wall 21 airtight, - At the joint 229, the wall 22 is formed by the continuity of the same material or two different materials by bi-injection molding.

[0161] The deformable walls 22 and 100 are - Grouped as a single part made of the same material without material discontinuities, or - It is manufactured as a single part by overmolding or bi-injection molding.

[0162] The wall 91 has screwing means 310 that can close or plug the reservoir 6 so as not to leak. During the screwing operation, the reservoir can extend and be lifted (move towards the wall 91) and / or deform towards the bottom wall 91. To close the neck of the reservoir 6, only the bottom wall 91 is rotated by an external tool (not shown).

[0163] When the screwing operation is completed, an axial force in the direction of the reservoir acts on the wall 91, making it possible to fix the wall 91 to the wall 12.

[0164] The wall 91 has fixing means 45 for the container 122. The fixing means preferably comprises an interlock (meshing connection), more preferably a snap fixing and interlock between the wall 91 and the container 122, more precisely between the wall 12 and the container 122. The wall 91 preferably allows the container 122 to be closed or sealed in a non-airtight manner.

[0165] The deformable wall 22 and the wall 12 of the container 122 are - grouped as a single part of the same material without material discontinuity, or - manufactured as a single part by overmolding or bi-injection molding.

[0166] Referring to FIGS. 24 to 29, the device 106 in FIGS. 24 to 29 is distinguished by the following elements. The flexible wall 108 of the reservoir 6 is itself surrounded by the wall 12 of the container 122.

[0167] First of all, it has an anti-rotation system for the reservoir 6: - In the embodiments common to FIGS. 24 to 28, this anti-rotation system takes the following form: o At least one relief 40, preferably multiple reliefs 40 (typically each being a recess or bump) of the wall 108 of the reservoir 6, o At least one relief 40, preferably a plurality of reliefs 40 (typically each being a bump or recess), located on the walls 12 and / or 21 and / or 91, configured to prevent rotation of the reliefs on the wall 108, thereby preventing rotation of the reservoir 6 (preferably, the reliefs on the wall 12 include at least one fin 19 extending along the extension axis of the container 122). - In the embodiment shown in Figure 29, the anti-rotation system comprises a square, polygonal, or more generally non-cylindrical shape of wall 108 and a square, polygonal, or more generally non-cylindrical shape of wall 12.

[0168] The wall 108 and the relief 40 are preferably manufactured by injection blow molding or extrusion blow molding. Note that the relief 40 is formed on the side wall 108 of the reservoir (relative to the extension axis of the reservoir). Neck 87 and Bump 60 have higher rigidity than the side walls of Reservoir 6.

[0169] The flexible sidewalls of reservoir 6 are typically about 0.15 to 0.4 mm thick to optimize the emptying of the reservoir. These thin walls create problems with rigidity when closing the reservoir. In contrast to the device in Figure 23, this anti-rotation device prevents excessive twisting of the reservoir (typically less than 20 degrees).

[0170] Wall 91 and plug 310 are two separate parts. The rails 90 allow the plug 310 to slide against the bottom wall 91. These rails can rotate the plug 310 as the wall 91 rotates, and this sliding can prevent the reservoir from being lifted when screwed in, and the plug 310 can move in parallel even if it comes into contact with the end of the side wall 12, particularly at the position of the interlock or snap fastening means 45, before the bottom wall 91 is interlocked. The plug is configured to slide against the side wall 12, at least at the end of the tightening.

[0171] The plug 310 is held within the part 91 (for example, by a clipping means having clearance that allows axial sliding) and can slide within the part 91. The plug is held against the wall 91 at the start of the pumping operation, but can be released from the bottom 91 after a certain number of pumping operations.

[0172] The wall 108 of reservoir 6 is equipped with a neck 85. The neck 85 of the wall 108 of reservoir 6 has threads configured to work with the plug 310.

[0173] The wall 108 is drilled on the opposite side of the neck 85 to form an opening 124 fixed to the bottom wall 21. The plug 310 is equipped with a recess 311 to reduce the amount of air in the reservoir 6 after sealing.

[0174] The container 122 is closed by pushing in part 91 after the screwing step of plug 310 into neck 85. The ribs or fins 19 inside the container 122 are configured to block the wall 108 of the reservoir 6 from moving.

[0175] Referring to Figure 25, the pocket wall 21 is first assembled with the flexible wall 108. Then, optionally, the valve 4 is inserted, and at least the assembly 21,108 is inserted into the container 122 up to the base of the wall 22, and the assembly is held in place by clamping the part 100 on the side of the pocket wall 21.

[0176] Note that elements 91 and / or 310 connected to the neck 85 are intermediate sections between wall 12 and wall 108. Components 91 and / or 310 are located at one end of device 106. Aside from the intermediate components 91 and 310 connected to the neck 85, there are no other intermediate components connecting wall 12 and wall 108, extending at least half (or at least two-thirds) of the extension from the neck 85 to walls 12 and 108, except outside the neck 85.

[0177] Furthermore, it should be noted that these or these intermediate components 91 and / or 310 are connected to the walls 12, 108 without adhesive, welding, or co-extrusion, which is advantageous for device recycling.

[0178] Therefore, these intermediate parts 91 and / or 310 are removable from the walls 12, 108 (by screwing or disengaging).

[0179] The distribution valve 5 is located inside a rigid component 70 supported by a movable wall 22, and this rigid component 70 is configured to translate due to the deformation of the movable wall 22. Wall 22 is continuous with part 70 by material, overmolding, or bi-injection molding.

[0180] Figures 30 to 33 show another embodiment of the fluid distribution device 107 according to the present invention. Only the differences from device 106 will be described.

[0181] Referring to Figures 30 to 33, the neck 85 has no threads. Means 84 hold the reservoir 6 while the plug 310 is inserted. Means 84 is a border or recess at the position of the neck 85. Tool 82 holds means 84 in place (by coupling with neck 85) during insertion of plug 310.

[0182] In the embodiments shown in Figures 32 and 33, the reservoir is compressible, which allows for a lower joint height between component 12 and component 91. Conversely, in the embodiments of Figures 30 and 31, the reservoir is not compressible, and the height of part 91 must allow the use of the tool 82, so the joint height between part 12 and part 91 must be greater.

[0183] Figures 34 and 35 show another embodiment of the fluid distribution device 1060 according to the present invention. Only the differences from device 106 will be described.

[0184] Referring to Figures 34 and 35, in this embodiment, the anti-rotation system for the reservoir 6 has the following configuration: - As shown in Figures 34 and 35 o One or more reliefs 40 (typically, each a recess or bump) on the wall 108 of reservoir 6, o One or more reliefs on wall 12 and / or 21 (typically bumps or depressions, respectively), which are configured to prevent rotation of the reliefs on wall 108 and thus prevent rotation of reservoir 6 (preferably these reliefs are located on wall 12 and comprise at least one fin 19 extending along the extension axis of the device), - In modified examples not shown, the wall 108 has a square or polygonal or more generally non-cylindrical shape, and the wall 12 has a square or polygonal or more generally non-cylindrical shape.

[0185] In the previously described embodiment, the openings 87 and 124 were separate and located on both sides of the reservoir 6 at two different positions (preferably opposite sides) of the reservoir 6. In contrast, device 1060 has openings 87 and 124 that are in the same position and coincide. The bottom wall 21 functions as a rigid wall 91 to which a screw fastening means 310 is provided. This screw fastening means 310 can be configured to slide in a sealed manner within the bottom wall 21, thereby preventing the reservoir 6 from being lifted when the bottom wall 21 (more precisely, the wall 44) is screwed in. Once the screwing operation is complete (the skirt of the plug allows for sealing), an axial force toward the reservoir at the base of the deformable wall 22 allows the heads of device 1060 (particularly the dispensing head) to snap in (thanks to the snap fastening means 47).

[0186] Figures 36 and 37 show a fourth embodiment of the device 4000 according to the present invention for distributing fluids. Only the differences from device 102 in Figure 4 will be explained.

[0187] Referring to Figures 36 and 37, in this embodiment, pocket 2 is defined as follows: - Partially defined by a deformable wall 22, and - Partially defined by the rigid wall of the distribution head 400, where the distribution head 400 is fixed to the deformable wall 22 of the pocket 2, but is supported and fixed to the deformable wall 22 to accommodate various possible positions relative to the reservoir 6, the possible positions include at least the following positions: * Stable position (position as shown in Figure 36), this is the position when no external force is applied to head 400, and * The inclined position is the position in which an external force acts on the head 400, inclined at an angle relative to the stable position so as to deform the deformable wall 22 and reduce the internal volume of the pocket 2 relative to the stable position. This external force is typically applied to the head 400 by the user's face and / or cheeks and / or lips and / or around the eyes.

[0188] The head 400 is equipped with a distribution surface 7, which preferably has a surface area of ​​at least 50 mm², and more preferably at least 70 mm², and is adjacent to or surrounding the outlet 24. The distribution component 23 has a distribution surface 7 and is fitted or screwed to one end of the hollow member 406, the other end of which is connected to the wall 22 by material continuity, overmolding, or bi-injection molding. The distribution surface 7 is configured for massage and to exert inclined force on the device.

[0189] The intake valve 4 is of the "duckbill" type, is particularly airtight, and allows the introduction of a needle through the valve 4. In this description, the "duckbill" valve may be a single-slit valve or a cross-slit valve.

[0190] The valve 4 may be manufactured by overmolding on the bottom wall 21. The bottom wall 21 constitutes a plug or insert to be inserted into pocket 2.

[0191] The degassing element 411 is configured such that when the plug 91 of the reservoir 6 is open and the piston 86 is absent, and the pocket 2 is filled with liquid and / or gel by a needle inserted from the side of the reservoir 6 through the valve 4 (or filling valve), gas can pass from the pocket 2 to the reservoir 6 during this filling.

[0192] This element 411 typically provides a valve, clearance, or gap between the wall 21 and the pocket 2, or a slot in the bottom wall 21. The pocket 2 is provided with a degassing means 411 at the location of the bottom wall 21, the degassing means 411 is located on the side of the reservoir 6 and faces the reservoir 6. Referring to Figure 37, in this embodiment, the valve 411 is sandwiched at the base of the pocket 2 between the bottom wall 21 and the head 400, or between the bottom wall 21 and the wall 118. In an unillustrated version, the valve 4 is sandwiched between the bottom wall 21 and the head 400 at the bottom of the pocket 2, or between the bottom wall 21 and the wall 118.

[0193] Wall 22 is connected to and fixed to wall 118. Wall 22 has continuity of material or overmolding or bi-injection molding with the wall 118 of reservoir 6 (as shown in Figure 36) and / or the wall 12 surrounding wall 118.

[0194] The wall 118 of reservoir 6 defines the internal volume of reservoir 6 (defining at least 50%, and moreover, at least 75%, of the internal volume of reservoir 6). Wall 12 surrounds wall 118, and wall 118 defines the internal volume of reservoir 6 (defining at least 50%, and moreover, at least 75% of the internal volume of reservoir 6).

[0195] The rigid wall of the head 400 is limited in its inclination by several contact points 401 (with the hole 412), 404 (with the hole 412), 402 (with the hole 412), and 403 (with the wall 21) through the through hole 412 and / or the wall 21. In addition to the part 23, the head 400 optionally includes a massage element 408 having two lateral massage surfaces relative to the product outlet, the contact points configured to prevent inclination during massage.

[0196] The distribution valve 5 is located inside a rigid component 400 supported by a movable wall 22, and as a result, the rigid component 400 is configured to tilt and / or move in parallel due to the deformation of the movable wall 22.

[0197] Wall 22 is continuous with part 400 by material continuity, overmolding, or bi-injection molding. Note that the extension axis of head 400 is substantially the same as the extension axis of reservoir 6.

[0198] Figures 38 and 39 show a fifth embodiment of the device 5000 according to the present invention for distributing fluids. The lid 222 comprises a wall 22 and a distribution surface 7. The pocket 2 is formed by the lid 222 attached to a bottom wall 21 that forms a “flat” pocket, and the bottom wall 21 and the lid 222 extend in the same direction. Below, only the differences from the device 105 in Figure 19 will be described.

[0199] In this embodiment, the valve 4 (more precisely, one end) is confined or pinched between the bottom wall 21 and the perimeter or bottom of the wall 22, particularly between the bottom wall 21 and the cover 222.

[0200] The degassing element 411 is configured to allow gas to pass from pocket 2 to reservoir 6 when filling the pocket 2 with liquid and / or gel using a needle inserted from the side of reservoir 6 with plug 91 open during filling and passing through valve 4. As shown in Figure 38, there may be several supply valves 4 and 4b used for filling in relation to several degassing elements 411 and 411b.

[0201] The degassing channel 211 connects element 411 to the supply opening 41. This element 411 typically includes a valve, a clearance or gap between the wall 21 and the pocket 2, and / or a slot in the bottom wall.

[0202] The degassing means 411, 211 are preferably directed toward the reservoir 6. The valve used to fill the pocket 2 is preferably configured such that the valve seat in the bottom wall 21 is close to the position of the reservoir 6, and is therefore preferably similar to valve 4b, but at the same time, it is preferable that the supply valve 4 is closest to the deformable wall 22. In another modification not shown, the distribution valve 5 is further away from the reservoir 6 than the supply valve 4.

[0203] Figures 40 to 44 show a sixth embodiment of the device 6000 according to the present invention for distributing fluids. Only the differences from the device 105 in Figure 13 will be explained.

[0204] Referring to Figures 40 to 44, in this embodiment, each means (typically a fence) for the internal guide 110 of the cap 70 is coupled to at least one rail 112 and / or slide 113, the rail 112 and slide 113 being configured to guide the cap 70 on the means 110. Figure 41 shows a fence 110 surrounding the rail 112 of the cap 70. In the modification shown in Figure 42, the fence 110 cooperates with a slide 113 of the cap 70, which is made of rail 112. Each rail 112 and / or slide 113 is integrated with the cap 70.

[0205] This rail / slide pair can be replaced or complemented by another rod / cylinder pair configured not to compress the product. Preferably, at least one rail / slide pair is configured to have a dovetail slide and lateral support in all directions, as shown in Figure 42.

[0206] The inhalation valve 4 is of the "duckbill" type, is particularly airtight, and allows the needle to be introduced through the valve 4. The distribution valve 5 is equipped with a stud 90 (or rod 90) fixed to the movable member of the valve 5.

[0207] Stud 90 is: - Partially contained within the deformable chamber 2 in the closed position of the distribution valve 5 (not particularly the ends of the studs 90), and / or - When the distribution valve 5 is in the open position, the entire structure is contained within the deformable chamber 2. The movable member of valve 5 is completely contained within the deformable chamber 2.

[0208] Distribution valve 5 is: - Partially contained within the deformable chamber 2 in the closed position of the distribution valve 5 (not particularly the ends of the studs 90), and / or - When the distribution valve 5 is in the open position, it is completely contained within the deformable chamber 2.

[0209] The end of the stud 90 is: - When the distribution valve 5 is closed, the outlet 24 of the chamber 2 is closed. - When the distribution valve 5 is open, it is further away from the outlet 24 of the chamber 2 compared to when the distribution valve 5 is closed.

[0210] The movable member of valve 5 is configured to move under the influence of fluid overpressure exceeding a pressure threshold (particularly dependent on the overall rigidity of the return means 696) with respect to the equilibrium state of chamber 2 within the internal volume of chamber 2, thereby moving the stud 90 away from the outlet 24 of chamber 2 and moving the distribution valve 5 from a closed state to an open state. Such overpressure can be caused by a decrease in the internal volume of chamber 2 filled with the fluid to be distributed, for example, when a user presses the pressure surface 25.

[0211] The movable member of valve 5 is configured to move in such a way that the stud 90 moves toward the outlet 24 of chamber 2 in order to keep valve 5 in a closed state or to change the distribution valve 5 from its open state to a closed state.

[0212] The movable member of the valve 5 includes at least one movable wall 91, which comprises at least one gas pocket 92. Each movable wall 91 is located inside a chamber 2 that is entirely deformable.

[0213] At least one gas pocket 92 contains a gas (typically air), preferably in such a way that it cannot escape from this pocket 92. At least one gas pocket 92 is configured to isolate this gas (represented as small dots in the figure) from the fluid contained in the deformable chamber 2.

[0214] The gas pocket 92 is completely surrounded by the fluid contained within the chamber 2 (along a closed loop that surrounds this pocket 92 360°). Each gas pocket 92 has a movable wall 91 that has a contact surface 697 configured to be in complete contact with the fluid contained in the chamber 2.

[0215] This contact surface 697 of pocket 92 is defined as the surface of the wall 691 on the first side configured to contact the fluid contained in chamber 2 (typically less than 1 mm thick, or preferably less than 500 μm thick). The other side of pocket 92 opposite to this first side is in contact with the gas, and the surface of the stud 90 is not counted.

[0216] The total area of ​​the contact surfaces 697 of the gas pocket 92 is at least 50 mm², more than 70 mm², and more than 90 mm².

[0217] The device 6000 includes a movable wall 691 of a gas pocket 92 aligned along the extension axis of the stud 90, which is also the displacement axis of the stud 90 between the open position and the valve closed position.

[0218] The pressure within each gas pocket 92 is typically as follows: - More than 1 atmosphere, and / or - Between 0.9 atmospheres and 1.5 atmospheres, preferably between 0.9 atmospheres and 1.1 atmospheres, preferably equal to 1 atmosphere.

[0219] The distribution valve 5 and at least one gas pocket 92 are part of a module 693 that is inserted into the device 6000 from the outside. Module 693 is fitted into the rest of the device 6000, more precisely into the cap 70. Module 693 is fitted into the rest of device 6000 in a sealed manner.

[0220] Module 693 has a reservoir or tube 602 with two diameters: - The smaller diameter section is a smaller diameter part for receiving the stud 90. - The large-diameter portion is configured to sink into the cap 70. Module 693 is equipped with a lid 603 that is fixed (usually by welding or fitting) to the reservoir or tube 602 and partitions the inside of the pocket 92 with a wall 691.

[0221] The movable members of the stud 90 and / or valve 5 are configured to come into contact with the fluid contained within the deformable chamber 2. The stud 90 is configured to be in only partial contact with the fluid contained within the chamber 2, and in fact, when the valve 5 is in the closed position, the end of the stud 90 is hidden inside the chamber 2 by the outlet 24.

[0222] The movable member of the valve 5 is configured to be in partial contact with the fluid contained within the chamber 2, and in fact, the movable wall 691 has an inner wall that is in contact with the gas in its pocket 92. The movable wall 691 is a series of bellows that form a thread.

[0223] The device 6000 includes at least one return means 696 configured to exert a return force on the stud 90 in order to push the stud 90 toward the outlet 24 of the chamber 2 in order to return the distribution valve 5 from its open position to its closed position.

[0224] At least one return mechanism 696 comprises a movable wall 691 in the form of a bellows. The movable wall 691 is configured to deform during movement.

[0225] Each gas pocket 92 facilitates for the user the transition of the valve 5 from the closed state to the open state, while simultaneously ensuring good closing of the valve 5 in the closed state. The internal volume of the deformable chamber 2 is at least partially defined by the cap 70.

[0226] The internal volume of the deformable chamber 2 is at least partially defined by the bottom wall 21 which forms a plug that is inserted into the pocket 2. The distribution seat is formed by all the contact points of module 693 between the distribution valve 5 and module 693 when valve 5 is in the closed position.

[0227] Note that there are no valves in the fluid circulation path between the supply port 41 (and / or valve 4) and the distribution valve 5. Note that there is no mechanical connection between the cap 70 and at least one pocket 92, and the only connection between the wall 25 and at least one pocket 92 is through the fluid being distributed.

[0228] Referring to Figures 43 and 44, Exit 24 is defined by the surrounding area, which includes: - So-called flexible parts 694 (e.g., depending on TPO) - A so-called rigid part 695 made of a harder or more rigid material than the flexible part 694 (e.g., made of polypropylene) (the two hardnesses are measured and compared in the same units from Shore A or Shore D). The rigid part 695 is closer to the outside of the deformable chamber 2 than the flexible part 694.

[0229] Component 694 is an independent, flexible component clamped between the inner walls of the reservoir or tube 602. Stud 90 is stiffer or harder than flexible and rigid parts (hardness is measured and compared in the same units from Shore A or Shore D).

[0230] For Stud 90: - Stud hardness greater than Shore D 30, or even greater than Shore D 70, and / or - Stud 90 has a flexural modulus exceeding 200 MPa or exceeding 500 MPa.

[0231] The stud 90 is either flush with the outlet 24 (as shown in the figure) or protrudes less than 1 mm from the outlet 24. The end of the stud 90 is less than 1 mm from the exit 24 (either in front of or behind the exit 24).

[0232] In the closed position of the distribution valve 5 shown in Figure 44, the end of the stud 90 is in contact with the flexible component 694 along a first contact line, preferably along the edge 651 of the stud 90. This first contact line is a closed contact line that wraps around the stud 90.

[0233] The edge portion 651 forms an angle of less than 150°, and even less than 90°, with respect to the side surface of the stud 90 in the cross-sectional view of the stud 90. In the closed position of the distribution valve 5 shown in Figure 11, the end of the stud 90 is also in contact with the rigid component 695 along the second contact line, preferably along the edge 652 of the stud 90. This second contact line is a closed contact line that passes around the stud 90.

[0234] In the cross-sectional view of the cap 70, the edge 652 forms an angle of less than 150° with respect to the reservoir 602. Note that in part 694, the surface immediately behind contact line 651 is not in contact with rigid part 695, and there is a space 699 between parts 695 and 694, which provides additional flexibility and makes it easier to obtain the two contact lines 651 and 652.

[0235] The stud 90 is configured such that when the valve 5 moves from its open position to its closed position, the first contact line is formed before the second contact line. The maximum distance between the first contact line and the outside of the chamber 2 on the outlet 24 side is less than 6 mm, and even less than 4 mm.

[0236] Referring to Figures 40, 41, and 42, note that device 6000 includes hole 65. More precisely, this hole 65 is located in the side wall of module 693.

[0237] The holes 65 allow air to escape from module 693 when the product to be distributed is filled into reservoir 3 and / or pocket 2 and / or valve 5 by a filling pipe, for example, passing through opening 87 and then opening 41. Preferably, the openings 87, 41, and 65 are aligned in that order, that is, a straight line can pass through these three openings in that order.

[0238] Figures 45 and 46 show one embodiment of the device 7000 for distributing fluid. Only the differences from the device 6000 shown in Figures 40 to 44 will be explained.

[0239] In this embodiment, at least one return means 696 includes a convex, flexible, movable wall 691 that forms a dome. Referring to Figures 45 and 46, in embodiment 7000, the valve 5 and outlet 24 are located along the stem 160 or at the end of the stem 160.

[0240] The stem 160 extends from the surfaces 22 and / or 25, and thus connects the surfaces 22 and / or 25 located at one end of the stem 160 to the valve 5 and outlet 24 located at the other end of the stem 160. This stem 160 has a channel that connects pocket 2 to outlet 24.

[0241] The length 161 of the stem 160 between one side surface 25 and the outlet 24 is at least 25 mm, preferably at least 35 mm, and even more preferably at least 45 mm. The inhalation valve 4 is of the "duckbill" type, is particularly airtight, and allows for the introduction of a needle through valve 4. The valve 4 can be manufactured by overmolding it onto the bottom wall 21.

[0242] The supply valve 4 is provided with protective means 204 configured to protect the valve 4 during insertion of an injector through the supply opening 41. This means 204 takes the form of a cone or a ring and is inserted into the bottom of the valve 4 (reservoir 6 side). This cone or ring 204 is either part of the bottom wall 21 or a separate additional part from the bottom wall 21 (however, it is preferably fixed to the bottom wall 21).

[0243] Wall 691 is inserted into the wall of applicator 208 from which exit 24 appears. The applicator 208 allows for spreading the product to be distributed and massaging a part of the human body (e.g., the face and / or cheeks and / or lips and / or around the eyes) with the distributed product.

[0244] The applicator wall should ideally consist of the following two layers: - On the side of wall 691 and / or valve 5, a layer of plastic material, for example, PP or PE, - On the outlet side, there may be a metal layer such as stainless steel, a sponge layer, or even a fabric layer. Preferably, the applicator 208 has a distribution surface adjacent to or surrounding the outlet 24 that has an area of ​​at least 50 mm², and more preferably at least 100 mm².

[0245] Figures 47 and 48 show one embodiment of the device 8000 for distributing fluid. Only the differences from the device 7000 in Figures 45 and 46 will be explained.

[0246] In this embodiment, the stem 160 extends from the surface 22, and thus the surface 22 located at one end of the stem 160 connects to the valve 5 and the outlet 24 located at the other end of the stem 160. The length 161 of the stem 160 between one side of the surface 22 and the outlet 24 is at least 25 mm, preferably at least 35 mm, and even more preferably at least 45 mm.

[0247] Due to the flexibility or deformability of the wall 22, the stem 160 is configured to tilt. In this embodiment, pocket 2 is defined as follows: - Partially defined by a deformable wall 22, and - Partially defined by the internal rigid wall of the stem 160 fixed to the deformable wall 22 of pocket 2, where the stem 160 (which forms the distribution head 400 as described with reference to Figures 36 and 37) is supported by the deformable wall 22 to accommodate various possible positions relative to the reservoir 6, the possible positions including at least the following: * Stable position (as shown in Figure 47), which is when no external force is applied to the stem 160, and * The inclined position is a position inclined at a certain angle relative to the stable position so as to deform the deformable wall 22 when an external force acts on the stem 160, thereby reducing the internal volume of the pocket 2 relative to the stable position. This external force is typically applied to the stem 160 by the user's face and / or cheeks and / or lips and / or eyes.

[0248] The means 204 takes the form of a cone or a ring and is inserted into the bottom of the valve 4 (on the reservoir 6 side). This cone or ring 204 is either part of the bottom wall 21 (as shown in Figure 48) or a separate additional part from the bottom wall 21 (however, it is preferable that it is fixed to the bottom wall 21).

[0249] Valve 4 is sandwiched between means 204 and / or bottom wall 21 on one side and between a rigid extension integral with wall 22 on the other side. The wall 691 and / or valve is fixed between the massage element 408 and the outlet 24 and / or applicator 208.

[0250] Figures 49 to 52 show one embodiment of the device 9000 for distributing fluid. Only the differences from the device 4000 in Figures 36 and 37 will be explained.

[0251] Walls 12 and 21 form a container 122 configured to house the reservoir 6 and pocket 2. The container includes a joint 175 between the upper part 170 and the lower part 180 of the container 122.

[0252] This joint 175 is: - As shown in Figure 49, the joint between each part 170 and 180 is by a flexible intermediate wall of the container 122, or - This is a rigid joint that connects two parts, 170 and 180, by fitting them together.

[0253] This joint is provided to allow for tilting of the head 400. The head 400 passes through the hole 173 made in the container 122, and as a result the head 400 comprises at least one outer portion 152 of the container 122 and at least one inner portion 202, 5, 22 of the container 122.

[0254] Component 23 includes a fixing means that allows the head 400 to be fixed to the container 122. This is illustrated as follows: - As shown in Figure 50 or Figure 51, a portion 171 of the container 122 (also called a fixing plate 171) is fastened between two parts of the assembled head 400. The head 400 comprises the following two parts: a first portion 151 (e.g., including threads 201 and fasteners 202) located at least partially inside the container 122, and a second portion 152 (e.g., a rider or ring) located at least partially outside the container 122 and at the end of the head 400, and fixed to the first portion 151. These two portions 151 and 152 may, for example, hold between them a distribution ball 150 (Figure 50) that rotates freely and opens to an outlet 24, or a distribution sponge or pad 150 (Figure 51) to which the outlet 24 is connected.

[0255] - As shown in Figure 52, a portion 171 (also called a fixed plate 171) of the container 122 is held by at least a portion of the head 400, the head 400 comprising, as at least a portion thereof: a first portion 151 of the head 400 (e.g., including a rider that holds portion 171 by jaws), which is at least partially located inside the container 122; and a second portion 152 of the head 400 (e.g., having a fork that is sandwiched between plate 171 and portion 151), which is at least partially located outside and at the end of the container 122 and at the end of the head 400. The parts 151 and / or 152 may hold a roller or applicator or dispensing ball 150 that is freely rotatable and through which the outlet 24 opens.

[0256] Accordingly, the reservoir 6 and head 400 constitute a replaceable cartridge 200 within the device 9000 according to the present invention by unlocking the fixing means 151, 152 and opening the cover 176 fixed to the lower part 180.

[0257] The container 122 is configured to allow translational motion between the reservoir 6 and the container 122 (within the cavity 181 formed in reference numerals 176 and / or 180) when the head 400 is tilted.

[0258] The device 9000 includes an adjustment means 172 configured to change the stiffness of the joint 175. The adjustment means 172 typically includes a tongue (metal) that slides between parts 170 and 180 to have several possible positions more or less distributed on parts 170 and 180.

[0259] Figure 53 shows one embodiment of device 10000 for distributing fluid. Only the differences from device 9000 in Figures 49 to 52 will be explained. Device 10000 differs from device 9000 in that the head 400 and the container 122 are not tiltable. In this case, section 175 is no longer a joint, but a pressing surface configured to deform the wall 22 of the head 400. Device 10000 is shaped like a pen.

[0260] Figures 54 and 55 show one embodiment of the device 11000 for distributing fluid. Only the differences from device 105 in Figure 13 will be explained.

[0261] In this embodiment, the bottom wall 21 (or the plug or insert 123 pressed into the cap 70) has a convex dome shape on the side of the internal volume of the pocket 2. The cap 70 is formed as a single component.

[0262] Typically, cap 70 is, - Formed from a single material, without any discontinuities in that material, or - A part made from two or at least two materials, obtained as a result of bi-injection molding or overmolding of one material onto another.

[0263] The cap 70 has a concave curved shape on the internal volume side of the pocket 2, which aligns with the convex shape of the bottom wall 21, leaving an intermediate space 2a between these concave and convex shapes, which is formed to reduce a portion of the internal volume of the pocket 2.

[0264] The majority 2b (at least 70%, preferably at least 80%) of the internal volume of pocket 2 is located within at least one cavity that sinks inward toward the bottom wall 21, and is distinct from portion 2a. The total internal volume of the pocket is comprised of the sum of parts 2a and 2b.

[0265] The cap 70 is fitted into the bottom wall 21 without welding. This fit is equipped with a snap 161. The seal of the fit is ensured by at least one sealing contact line 260 (or sealing ring) between the cap 70 and the bottom wall 21. Several sealing contact lines 260 (or sealing rings) may be present, and in some cases may be grouped together in the form of sealing bands.

[0266] The boundary of the internal volume of pocket 2 is far from these sealing contact lines 260. A recess 2b is formed in the bottom wall 21, defining at least a portion of the internal volume of the pocket. The sealing contact line 260 is sometimes more than 10 millimeters away from this recess 2b, or even from the internal volume of the pocket 2 in general.

[0267] The periphery of the recess 2b is smaller than the periphery of each contact rib 260, at least 30% smaller, more preferably at least 50% smaller, and even more preferably 70% smaller. The sealing strip 260 surrounds the internal volume of pocket 2 but does not form a boundary.

[0268] In addition to compressing the flexible wall 108 to prevent leakage, the ring 109 has the additional function of more precisely holding the supply valve 4 by compressing the legs of the valve 4 on the skirt of the bottom wall. The ring 109 is placed between the two cylinders of the bottom wall and is positioned to clip onto the outer wall of the smaller cylinder.

[0269] The supply valve 4 is provided with protective means 204 configured to protect the valve 4 during insertion of an injector through the supply opening 41. Formed on the ring 109, this means 204 is advantageous to be conical or to be inserted into the position of the ring 109. It includes an opening 137 at the base of the valve 4 (on the reservoir 6 side) and / or an opening 41 that is smaller (preferably at least 15% smaller in diameter) than the opening 137 at the base of the valve 4. Valve 4 is held between ring 109 and bottom wall 21.

[0270] Above the contact line 260, a portion of the reservoir penetrates the inside of the bottom wall 21, and the bottom wall 21 is convex on the pocket 2 side but concave on the reservoir 6 side.

[0271] The volume of pocket 2 is at least 2, 3, or 4 times smaller than the internal volume of cap 70 defined by the (intermediate) plane passing through rifle 260. The cap 70 and bottom wall 21 are positioned so that the wall 21 is installed inside the cap 70 according to the insertion assembly into the cap 70 on the wire 260 side and in the insertion direction 125.

[0272] The pressing surface 25 and the outlet 24 are not oriented sideways, that is, both are positioned above the cap 70. - The distributed product exits through outlet 24 with at least one component in the insertion direction 125 (20% or more of the outflow direction vector), or the angle between the tangent to the surface surrounding outlet 24 and direction 125 is between 20° (preferably 45°) and 90°, and - The pressing surface 25 is configured 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 the tangent to the surface 25 and the direction 125 is between 20° (preferably 45°) and 90°.

[0273] The pressing surface 25 is equipped with a structure 133 that allows the surface 25 to be visualized.

[0274] Therefore, the device 11000 for distributing fluid includes the following: - Exit 24, - A pocket 2 having an internal volume for containing fluid, the internal volume of this pocket is, The cap 70 is partially defined by a movable wall 22 configured to tilt and / or translate and / or deform by pressing a pressing surface 25 to change the internal volume of the pocket. • Partially defined by the bottom wall 21 inserted into the cap 70, - The distribution valve 5 allows fluid to flow from pocket 2 to the outlet when open, but does not allow it when closed. - Reservoir 6 with walls 118, 108 configured to contain fluid, - A supply valve 4 that, when open, allows the fluid contained in the reservoir to pass into the pocket, and when closed, does not allow it.

[0275] Furthermore, the bottom wall 21 comprises the following three distinct parts: - The central portion 141, which partially defines the internal volume of the pocket, is positioned at a distance from the cap 70, and the space between the cap 70 and this central portion of the bottom wall 21 at least partially defines the internal volume of the pocket 2. - The intermediate portion 142, which surrounds the central portion of the bottom wall 21 and is configured to be pressed against the cap 70, is such that an intermediate space is created between the cap 70 and the bottom wall 21. The bottom wall 21 has an average of less than 2 millimeters in this space, preferably less than 1 millimeter in average. - Peripheral portion 143, which surrounds the middle portion of the bottom wall 21, is configured to form at least one sealing wire 260 together with the cap 70 within a closed loop between the cap 70 and the bottom wall 21. The intermediate portion has an area of ​​400 square millimeters or more (preferably 800 square millimeters or more), and / or is larger than (preferably at least twice) the area of ​​the central portion 141 of the wall 21.

[0276] The wire 260 forms a perimeter loop of at least 200 mm, preferably 250 mm or more, and even more preferably 300 mm or more.

[0277] Figures 56 and 57 show one embodiment of the device 12000 for distributing fluid. Only the differences from the device 11000 in Figures 54 and 55 will be explained.

[0278] The pressing surface 25 and the outlet 24 are positioned on the front, that is, both on the top of the cap 70. - The distributed product exits through the outlet 24 with at least the majority of its components (50% or more of the outflow direction vector) aligned with the insertion direction 125, or the angle between the tangent to the surface surrounding the outlet 24 and the direction 125 is between 20° (preferably 45°) and 90°, and - The pressing surface 25 is configured to be moved by a force having at least one component (50% or more of the force vector) opposite to the insertion direction 125, or the angle between the tangent to the surface 25 and the direction 125 is between 20° (preferably 45°) and 90°.

[0279] The portion 2b of the internal volume of pocket 2 further comprises an additional volume (typically crescent-shaped and / or surrounding valve 4). This additional volume can increase the internal volume of pocket 2 and thus reduce the pressure inside pocket 2 when pressing surface 25.

[0280] The curved or dome-shaped wall 22 or 25 (or spherical cap) may be replaced by a wall 22b having a point-like apex, and / or a wall 22b that is conical (basically circular, oval, elliptical, etc.) or pyramidal (may have three or more sides), and preferably slightly higher than the spherical cap placed on the wall at the base of this wall 22b, or higher than the spherical cap placed more upward at a height of 25% of the height of this wall 22b (or on the average wall if the shape is not spherical). The wall 22b is at least 0.3 mm higher than the wall 22 and deforms more gently. The ratio of the circumference of the bottom of the pocket 22b to the height of the pocket 22b is less than 20, and even less than 19.

[0281] The wire 260 forms a perimeter loop of at least 200 mm, preferably 250 mm or more, and even more preferably 300 mm or more.

[0282] Figures 58 and 59 show one embodiment of the device 13000 for distributing fluid. Only the differences from device 101 in Figure 1 will be explained.

[0283] The wall 22 is not located within the reservoir 6, and the outlet 24 is laterally to the device's extension axis and / or pressing surface. The device includes a plug 241 for filling the reservoir 6, which is fixed or screwed to the deformable wall. The device is provided with a rigid pressing wall 128 (derived from molding with the plug 241) for pressing the deformable wall 22. This pressing wall 128 is integral with the plug 241 and has a width equal to at least one-third of the width of the deformable wall 22 (measured along a measuring axis parallel or substantially parallel to the bottom wall 21).

[0284] The wall 22 is provided with a skirt 155 that has at least the same height as the entrance to the cavity 8 on the pocket 2 side in the same measurement direction (minimum 1 mm or 2 mm).

[0285] The skirt 155 allows the valve 5 to be inserted into the cavity 8 from the inside of the pocket 2, perpendicular or substantially perpendicular to the direction in which the height of the skirt 155 is measured. Thanks to this skirt 155, the bottom wall 21 takes the form of a flat surface 156, facilitating the welding of reservoirs 6, 14, or 108 to the bottom wall 21.

[0286] Figures 60 to 62 show one embodiment of the device 14000 for distributing fluid. Only the differences from the device 11000 in Figures 54 and 55 will be explained.

[0287] In this embodiment, pocket 2 is located laterally. - The angle between the tangent to surface 25 and direction 125 is between 0° and 45° (preferably 20°). Pocket 2 is arranged around the reservoir 6 and insert 123, orbiting 360° around direction 125.

[0288] There are one or two filling holes 87, 87b (as in device 101), each opening to the inside of reservoir 6. Preferably, there are two of these filling holes, located on either side of the outlet 24. These filling holes penetrate the cap 70 and the insert 123, and together they form an end piece 89 (equivalent to the end piece 89 of device 101).

[0289] A single plug 310 is configured to do the following simultaneously: - To seal the filling holes 87 and 87b, - Plug and / or protect outlet 24. It forms at least partially the applicator 208 and / or the distribution surface 207. The plug 310 includes a removable plug 77 by a hinge.

[0290] The plug 310 is equipped with two cylindrical pins 313, which, with minimal tightening, fit into the end piece 89 at the positions of the filling holes 87, 87b, in order to align and precisely maintain the plug 310 together with the end piece 89 during assembly. This is the primary means of securing the plug 310 in assembly on the end piece 89, allowing the assembled fixture to be maintained by complementary, independent clips. The diameter of the pins 313 is preferably greater than 3 mm, and even greater than 4 mm. Preferably, both holes 87, 87b are open, however, in versions not shown, one of the holes 87 or 87b is not open, and this unopened hole is referred to as the adjustment hole or positioning hole.

[0291] The plug 310 has a cavity 312, which is configured to receive the end of the distribution component 23 having an outlet 24. The distribution component 23 may or may not pass through the plug 310.

[0292] Device 14000 is equipped with a distribution surface 207 through which the outlet 24 opens. The distribution surface 207 has an area of ​​at least 80 mm², and moreover, at least 160 mm². The distribution surface 207 may be formed by the plug 310 and the end piece 89.

[0293] The plug 310 includes an applicator 208 having a dome shape 308 or a spout shape 309, which is at least partially formed by the plug 310. The insert 123 comprises, or at least partially comprises, a deformable wall 108, thereby defining, at least partially, the internal volume of the reservoir.

[0294] The insert comprises at least 20% of the internal volume of the reservoir 6. Depending on the nature of the device, the insert contains at least 3 ml, 10 ml, or even at least 20 ml of the product to be dispensed. In the portion containing the insert, at least 80%, or even 90%, of the reservoir 6 is deformable.

[0295] The reservoir (its internal volume) does not exceed the supply valve 4 toward the outlet, and there is no reservoir portion between the supply valve and the distribution valve along the shaft 125. The wall 108 is blow-molded (typically by either injection blow or extrusion blow) to form a reservoir 6 on which the neck is fixed onto the insert 123. The indexing means 236 (typically comprising fingers) for the cap 70 relative to the insert 123 is configured to be housed within a recess 234 of the insert 123.

[0296] Referring to Figure 62, at least one channel 238 is configured to allow good fluid flow to properly fill the pocket 2 and to locally increase the space between the insert 123 and the cap 70.

[0297] The wire 260 forms a perimeter loop of at least 200 mm, preferably 250 mm or more, and even more preferably 300 mm or more. The container 122 has a clipping means 235 on the insert 123 or on the cap 70, and is configured to allow disassembly of the cartridge or refill 200.

[0298] The wall 108 is deformable (including inside the insert 123) and is configured to fold or contract inward towards the insert 123 when there is no more fluid to be distributed from the reservoir 6. At least 10% or 20%, and even 30%, of the maximum volume of the reservoir is inside the insert 123. There is at least one cross section perpendicular to direction 125 that passes through pocket 2 and reservoir 6 (in particular, the wall 108 folds back or contracts inward towards the insert 123 when reservoir 6 is empty of the fluid to which it is distributed), i.e., pocket 2 and reservoir 6 are at least partially, at least 20% or 30%, at the same level. 5%, and even 40%, of the length of the pocket is at the same level as reservoir 6 in direction 125. At least 6mm or 15mm, and even 25mm, of the length of the pocket is at the same level as reservoir 6 in direction 125.

[0299] There exists at least one cross-section perpendicular to direction 125 that passes 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%, and even 35% of the length of the deformable wall 25 in direction 125 is at the level of the reservoir 6. At least 4 mm, 8 mm, and even 15 mm of the length of the deformable wall in direction 125 is at the level of the reservoir 6.

[0300] Note that the bond and / or seal between the cap 70 and the insert 123 may be on the inside of the cap 70 (as shown in Figure 60) and / or on the outside of the cap 70.

[0301] Pocket 2 is defined at least partially between insert 123 and cap 70. Pocket 2 surrounds Reservoir 6 360° around direction 125. Pocket 2 is - Distributed along direction 125 over at least 20%, and even more than 30%, of the height of device 14000, and / or - It has a height of at least 25 mm, 30 mm, and even 40 mm along direction 125.

[0302] Figure 63 shows one embodiment of the device 15000 for distributing fluid. Only the differences from the device 14000 shown in Figures 60 to 62 will be explained. Compared to the previous embodiment, in device 15000, the flexible wall 108 is fixed between the cap 70 and the insert 123 (by clamping or otherwise).

[0303] Therefore, the internal volume of the reservoir is, Within the insert 123, the insert 123 itself forms at least partially a rigid wall of the reservoir, and the reservoir is defined by the formed rigid wall of the reservoir. There is at least one cross section, which is perpendicular to direction 125 and passes through pocket 2 and reservoir 6 (and through insert 123 and cap 70), i.e., pocket 2 and reservoir 6 are at least partially on the same level.

[0304] However, when reservoir 6 is maximally filled with the fluid to be distributed, there is no at least one cross-section perpendicular to direction 125 that passes through pocket 2 and through the flexible wall 108 that folds or shrinks inward toward the insert 123 when the fluid to be distributed from reservoir 6 is empty. Instead, there is at least one cross-section perpendicular to direction 125 (closer to valve 4 than the aforementioned cross-section) that passes through pocket 2 and through reservoir 6 (in particular, even after passing through the rigid component 240 of the reservoir wall, when the fluid to be distributed from reservoir 6 is not empty and the wall is not folded or shrinks inward toward the insert 123).

[0305] - On the other hand, when a certain amount of fluid is no longer distributed from the reservoir 6 and the flexible wall 108 folds or contracts inward toward the insert 123, there exists at least one cross-section perpendicular to the direction 125 that passes through the pocket 2 and passes through the flexible wall 108, as shown in Figure 63. - Outside of insert 123, by the flexible wall 108.

[0306] The volume of the reservoir 6 outside the insert 123 is at least 40% larger than the volume of the reservoir 6 inside the insert 123. Such assembly is made possible by the hole 87, which allows the insert 123 to be pulled toward the cap 70.

[0307] Figures 64 to 66 show one embodiment of the device 16000 for distributing fluid. Only the differences from the device 14000 shown in Figures 60 to 62 will be explained. In this embodiment 16000, the insert 123 extends to the outside of the cap 70.

[0308] The internal volume of reservoir 6 is no longer defined (even partially) by the flexible, deformable wall 108, but is defined by the insert 123 and a movable piston 86 that moves within the insert 123 in accordance with the amount of fluid to be distributed and contained in reservoir 6.

[0309] This embodiment 16000 is equipped with a vent 321, which allows air to circulate between the outside of the device 16000 and a portion located inside the insert 123 but outside the reservoir 6 (a portion whose volume changes depending on the position of the piston 86). Ventilation opening 321 extends beyond pocket 2. The wall 22 (preferably flexible) is sandwiched between the cap 70 and the insert 123.

[0310] There exists at least one cross-section perpendicular to direction 125 that passes through pocket 2 and reservoir 6 (and through insert 123 but not through cap 70), i.e., pocket 2 and reservoir 6 are at least partially at the same height.

[0311] Device 16000 includes means 233 at the location of the vent 321 for sealing the space between the insert 123 and the wall 22. Pocket 2 is at least partially defined between the insert 123 and the wall 22 held between the cap 70 and the insert 123.

[0312] Pocket 2 surrounds Reservoir 6 360° around direction 125. Pocket 2 is - Distributed along direction 125 over at least 30% (preferably at least 50%) of the height of device 16000, and / or - It has a height of at least 30 mm, 40 mm, and even 50 mm along direction 125.

[0313] The insert 123 has a bottom wall 21. The internal volume of pocket 2 is at least twice (preferably at least four times) smaller than the internal volume of reservoir 6.

[0314] The hole 237 passing through the insert 123 connects 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 deformable flexible wall 22.

[0315] Therefore, insert 123 has the following functions: - Hold the wall 22 between insert 123 and cap 70. - Supporting hole 237, - Define the internal volume of pocket 2 at least partially, - Define at least partially the internal volume of reservoir 6, - Guides the movement of piston 86, - Holding the sealing means 233, - Supports one end of the ventilation opening 321.

[0316] Therefore, all these functions are provided by the component 123 of the end piece 89. The end piece 89 (more precisely, the insert 123) forms the side wall of the reservoir 6.

[0317] In this embodiment 16000, the following are included: - Holes 87, 87b for filling reservoir 6, - Holes 187 and 187b to fill pocket 2. The reservoir 6 is located between the valve 4 and the vent 321.

[0318] There exists at least one cross-section perpendicular to direction 125 that passes through pocket 2 and reservoir 6 (and through insert 123 but not through cap 70), i.e., pocket 2 and reservoir 6 are at least partially at the same height. The internal volume of pocket 2 is at least partially defined between the insert 123 and the wall 22 held between the cap 70 and the insert 123.

[0319] The wall 22 has the shape of an outer pocket. Wall 22 forms the lateral outer wall of the device and the bottom outer wall on the wall 91 side. The cap 70 is fixed to the open end of the pocket 2 formed by the wall 22. Reservoir 6 is located at least partially inside pocket 2.

[0320] In a variation not shown in Figure 64, the reservoir 6 is at least partially defined by a flexible wall 108 as in Figure 55 or 56, and the valve 4 and vent 321 are on the same side of the reservoir 6. The vent 321 penetrates the insert 123 and the cap 70. A wall 22 (preferably flexible) is sandwiched between the cap 70 and the insert 123.

[0321] Figure 67a shows one embodiment of the device 17000 for distributing fluid. Only the differences from the device 16000 shown in Figures 64 to 66 will be explained.

[0322] In this embodiment, the insert 123 extends to the outside of the cap 70. Similar to the embodiment in Figure 56, the internal volume of the reservoir 6 is defined by a deformable flexible wall 108 that is closed by a bottom wall 91 fixed by an insert 123. This flexible wall 108 is located inside the insert 123.

[0323] The device 17000 includes a replenishment connector 225 configured to allow the fluid to be refilled into the inside of the device 17000 (more precisely, into the inside of the reservoir 6) without the fluid passing through the pocket 2 or the distribution valve 5 or the supply valve 4.

[0324] Connector 225 is equipped with a filling valve, which is, - It is closed when stationary, and - When means 225 is connected to a fluid source to which fluid is distributed, it is configured to open. Connector 225 is removable.

[0325] The reservoir 6, more precisely the wall 91, protrudes outward and forms a neck with a slope 224 to prevent air from becoming trapped inside the reservoir 6.

[0326] Furthermore, the sealing means 218, located more precisely within the connector 225 or at the neck 85 of the device, prevents air from entering the reservoir 6 when it is refilled. The valve on connector 225 opens towards the inside of reservoir 6. Connector 225 penetrates wall 91. Insert 123 is sandwiched between wall 22 and wall 91.

[0327] There exists at least one cross-section perpendicular to direction 125 that passes through pocket 2 and reservoir 6 (and through insert 123 and wall 108), i.e., pocket 2 and reservoir 6 are at least partially at the same height.

[0328] The internal volume of pocket 2 is defined, at least partially, between the insert 123 and the wall 22. Pocket 2 (and wall 22) surrounds reservoir 6 in a 360° radius in direction 125. Reservoir 6 is located at least partially inside pocket 2.

[0329] The connector 225 is located at the height of the opening 87 and is blocked by the plug 310. The connector 225 allows both pocket 2 and reservoir 6 to be filled. The cover or handle 226 covers the neck 85 and wall 91 of the connector 225, concealing them from the outside of the device.

[0330] In another variation not shown in the illustration, the connector 225 and / or valve 4 is equipped with a “duckbill” type valve, which allows for the introduction of a filling pipe 46 that can fill the reservoir 6 and / or pocket 2 with the fluid to be distributed.

[0331] The filling pipe may have the following two holes: - A first hole 68 opening into pocket 2 (preferably located at the end of a filling pipe introduced into the device), and - A second hole 67 opening into the reservoir 6 (preferably located laterally along the filling pipe). Note that in this modification, filling under pressure is not performed.

[0332] A spring element 212 is interposed between the insert 123 (more precisely, the bottom wall 21 of the insert 123) and the wall 22. This element 212 may be present in the variations shown in Figures 67a, 67b, or 67c, and even in Figure 64.

[0333] The wall 22 is fixed onto the insert 123, more precisely, into the groove of the insert 123. The device includes clipping means 213 for clipping the pocket 22 onto the insert 123, more precisely, the ring 213 is clipped into the groove of the insert 123.

[0334] The ring 213 further includes a retaining means 214 for holding the end of the applicator 208 and securing the applicator 208, such as a rim 223 or rim area surrounding the device from the side. The applicator is removable and has less elastic end elements on its periphery to grip the rim 223.

[0335] The wall 22 is flexible and is injection molded from a thermoplastic elastomer, such as TPO. The distribution valve 5 is inserted into the wall 22. The valve 5 is more flexible than the wall 22 in the increased thickness portion of the wall 22 in which the valve 5 is housed.

[0336] In another modification shown in Figure 67c, the cap 70 comprises several walls 22, each wall 22 having its own valve 5, each valve 5 connecting to a common pocket 2. This allows the product coming from the reservoir to be distributed over a larger surface area. Optionally, all these walls 22 are covered by the same porous surface 208. The volume portion 217 is typically made of foam and is configured to eliminate any height differences between the portions of the cap 70, with or without the walls 22.

[0337] The method for filling device 17000 is as follows, and is applicable to any embodiment or modification of the device according to the present invention having an opening 87. 1) The reservoir 6 and / or pocket 2 are filled through the opening 87, even if the connector 225 is not attached to this opening 87, or even if a "duck valve" type valve is simply attached, as shown in Figure 67b.

[0338] Typically, a filling pipe 46 having two or at least two holes may be used: - A first hole 68 (preferably located at the end of the filling pipe introduced into the device), which opens into pocket 2, and - A second hole 67 (preferably located laterally along the filling pipe), which opens into the reservoir 6. and, 2) If the device is not equipped with a "duck valve" used for filling in step 1, a connector 225 is fitted to the opening 87.

[0339] 3) Reservoir 6 and / or pocket 2 are at least partially emptied by the use of the device, and thereafter, 4) The reservoir 6 and / or pocket 2 are filled through the opening 87 while the connector 225 and / or sealing means 218 are attached to the opening, as shown in Figures 67a and 667d.

[0340] In the modified examples shown in Figure 67d, Figures 67a, 67b, and 67c, the device according to the present invention does not include the connector 225. The filling is carried out through a "duck valve" type filling valve 219 connected to reservoir 6.

[0341] The two means or filling heads 220 and 221 enable the following filling, respectively: - Filling reservoir 6 and pocket 2 for the long tool 220. During the initial filling of reservoir 6 and pocket 2 by tool 220, air 210 coming from reservoir 6 can escape through valve 219. - Filling the reservoir 6 for the shorter tool 221 rather than for the longer tool 220. The neck 75 connected to the tool 221 or valve 219 is equipped with a sealant 218 positioned between the neck 75 and the tool 221, so that during the second filling of the reservoir 6, the air 210 cannot pass through the valve 219 and, in particular, cannot enter the reservoir 6 through the valve 219.

[0342] Next, various embodiments of the device according to the present invention will be described with reference to Figures 69a to 70c.

[0343] All embodiments of these Figures 69a to 70f share the following common feature: material continuity or overmolding or bi-injection molding: - Cap 70 (if available, otherwise generally a pressing wall 25), - Deformable wall 22, - A movable wall 420, which is configured to translate inside the conduit or cylinder 430 or outside the piston 430, is configured to translate through a rail 112 coupled to a slide 113, and the rail 112 and / or slide 113 are configured to guide the cap 70 (or pressing surface 25).

[0344] The rail 112 or slide 113 is fixed to (more precisely formed on) the cap 70, while each of the slide 113 or rail 112 is fixed to the bottom wall 21 or component 430 (or at least partially to a fixed portion that defines the internal volume of the pocket). This rail / slide pair may be replaced or supplemented by another rod / cylinder pair configured so that the fluid is not compressed and does not define the boundary of the pocket 2.

[0345] Preferably, at least one rail / slide pair is configured to have lateral support in all directions (perpendicular to the pressing direction 140). The outlet 24 is equipped with a nozzle 59 configured to generate a spray.

[0346] Next, an embodiment of the device according to the present invention will be described with reference to Figure 69a. This embodiment will only describe the differences from the embodiment in Figure 4.

[0347] In this embodiment, the deformable wall 22 does not define the internal volume of the pocket 2, at least partially. The deformable wall 22 is in contact with the air pocket 34 (the outer pocket 34 containing air). In this embodiment, the movable wall 420 defines at least a portion of the internal volume of the pocket 2 (together with the conduit 430).

[0348] The cap 70 further comprises a distribution spout 30 that supports the outlet 24. This distribution spout 30 extends laterally beyond the width of the side wall 118 that defines or accommodates the reservoir 6. The distribution spout comprises a distribution cavity 8 that extends to or beyond the side wall 118.

[0349] The movable part 420 sinks to its maximum extent within or around part 430, leaving a portion 36 of part 430, and part 420 does not sink into part 430 by a distance of at least 20 mm and at least 30 mm. Pocket 2 leaves a portion 36 between the supply opening 41 and the bottom wall 21 that has a length of at least 20 mm and a further 30 mm.

[0350] The spout 30 is equipped with a nozzle 59 that generates a spray. This embodiment further includes ribs 37 from the bottom wall 21 around the pocket 2, particularly around its portion 36, configured to prevent the pocket 108 from sinking into the device.

[0351] The entirety of each part 108, 112, 6, 87, 2, 70, and 122 is arranged inside cases 170 and 180, and the cases are an assembly of the upper case part 170 and the lower case part 180. The spout extends from the case, preferably, - Through the holes formed in the upper part 170, or - Through the hole formed between the upper part 170 and the lower part 180.

[0352] The spout 30 is part of the cap 70, which is in the form of a single piece made of the same material (without material discontinuities). The cartridge 200 is formed by assembling the reservoir 6 and the chamber 2 (and preferably the cap 70 and / or valve 4 and / or valve 5).

[0353] Once parts 170 and 180 are assembled, even if the cap 70 is pressed, the upper skirt 145 blocks the cartridge or refill 200, thereby preventing the cartridge 200 from moving within this embodiment of the device according to the present invention.

[0354] Referring to Figures 69b and 69c, the upper part 170 is, - Component 178 forming a button configured to press the cap 70, - Part 177 that forms a movable ring surrounding button 178, further - It includes an intermediate part 179, which is positioned between parts 177 and 178, is movable, and includes a clipping means configured to clip onto the lower part 180, such that pulling on part 177 releases the clip from the lower part.

[0355] Next, embodiments of the device 19000 according to the present invention will be described with reference to Figures 70a to 70h. Unless otherwise specified, only the differences from the embodiment in Figure 4 will be described for these embodiments.

[0356] In this embodiment, the deformable wall 22 does not define the internal volume of the pocket 2, at least partially. The deformable wall 22 may include an elastic tongue extending over the bottom wall 21 on the outside of the piston 420.

[0357] In this embodiment, the movable wall 420 defines the internal volume of the pocket 2 at least partially (together with the conduit 430). The outlet 24 is provided with a nozzle 59 configured to produce a spray. The device 19000 does not have a cap 70. The bottom component 289 comprises a bottom wall 21. The bottom component 289 comprises mounting means 89 to the reservoir, i.e., an end piece 89.

[0358] The deformable wall 22 is in contact with the outer pocket 34, which contains the fluid surrounding pocket 2 and is configured to receive fluid coming from the reservoir by connecting pocket 2 to the reservoir through the opening 163. The volume of pocket 34 is larger than the volume of pocket 2, preferably at least twice as large.

[0359] The button 250 has a deformable wall 22 and defines an elastic pocket 255 having pockets 2 and 34 by a bottom component 289 or 245, the pocket 34 of the device being configured to form a fluid passage from reservoir 6 to pocket 2.

[0360] The elastic pocket 255 is defined by the bottom wall 249 of the bottom part 289 or 245 and the button 250. The button 250 has a deformable wall 22 and comprises a continuous or discontinuous curved surface, which may be interpolated by two or three discontinuous slopes as shown below: - A first inclined surface 50 or central portion 50, which is preferably non-deformable or slightly deformable compared to the wall 22, preferably forming an angle of 0° to 20° with respect to a plane perpendicular to the compression axis 290 of the bottom wall 21 or pocket 2; - A second slope 51 of the deformable wall 22 around the first slope, which forms an angle of 25° to 75° with respect to a plane perpendicular to the compression axis 290 of the bottom wall 21 or pocket 2; - A third slope 52 of the deformable wall 22 around the second slope, which forms an angle of 50° to 100° with respect to the base wall 21.

[0361] This first slope or central portion 50 is substantially located in the center of the button and is more rigid than the deformable wall 22 (usually formed of a thicker wall) that surrounds it, and therefore more rigid than the slopes 51 and / or 52.

[0362] The button's deformable wall 22 is integrated with the central wall 50. This additional thickness of the slope 50 or central wall 50 not only constitutes the braking means 55 of the wall 22, but the hollow and / or bumps at the paired positions of the rail / slide, or the mounting of the piston 420 in the conduit 430, can also enhance this braking.

[0363] The braking means 55 is made of part 50, configured to deform over a larger periphery of the wall 22 compared to the pressing pressure which would be more point-like without part 50. The wall 50 has a surface area of ​​at least 50 mm², more preferably at least 70 mm², and even more preferably at least 100 mm², having a movement guided by the guide means 251 to prevent the wall 50 from yielding in the face of maximum pressing pressure. The central wall 50 of the button 250 has a width of at least 8 mm, more preferably at least 10 mm, and even more preferably at least 12 mm (measured on a 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 part 50 and is parallel to the guide means 251.

[0364] The pressing force is configured to decrease by at least 30% or at least 40% (from the stationary position) at the start of movement of the central portion 50. The maximum pressing force 140 on the pressing surface 25 (in the undeformed state of the wall 22) for causing deformation of the wall 22 is preferably at least 1.6 times, even more than 1.8 times, and even more than 2 times greater than the force required to be applied to the button to continue deformation between the first and second millimeter displacements of the pressing wall 25 toward the bottom wall 21 and / or between the second and third millimeter displacements of the pressing wall toward the bottom wall.

[0365] The guide means 251 comprises at least one guide wall and preferably at least one rail 112 and / or slide 113, and these guide means 251 are integrated with the central wall 50. The guide means 251 preferably comprises just one to three guide means (or rail 112 and / or slide 113), but preferably two guide means (or rail 112 and / or one slide 113). In the case of a single guide means, it may preferably comprise a cylinder opened at least 240°.

[0366] The central wall 50 of the button 250 is thicker than the wall 22 and / or reinforced by the guide means 251, and is integral with the wall 22 or, if including a strip, a portion of the wall 22. The guide element 251 is directed toward the bottom wall 249 of the elastic pocket 255 and is substantially parallel to directions 140 and 290, preferably substantially perpendicular to the wall 50 (perpendicular to the surface of the wall 50 on the elastic pocket 255 side).

[0367] The guide means 251 (more precisely, the rail 112 and / or slide 113) is configured to guide the pressing surface. Element 251 is located within pocket 34 but not within pocket 2 and does not pass through the bottom wall 249 (or bottom wall 21).

[0368] The guide means 251 (or guide wall 251) of the button 250 and the central wall 50 are configured to guide the pressing surface 25 in translation. The button guide means 251 is configured to cooperate with the fixing element 252 and / or the hollow portion 252 of the bottom wall 249 of the bottom part 289.

[0369] The movable wall 420 is integrated with the central portion 50, which is itself integrated with the wall 22, and there is continuity of material between the deformable wall 22, the wall 50 and the piston 420. Pocket 34 surrounds pocket 2, is defined by wall 22, and is partially defined by wall 50 by at least 10%, and moreover by at least 20%.

[0370] The wall 22 of button 250 forms a return mechanism for the movable wall 420 and wall 50, and the piston 420 is configured to translate either inside the conduit 430 or outside the piston 430. Around the piston 420 and the conduit 430 or piston 430, guide means 251 cooperate with a bottom wall 249 (fixed element 252 and / or hollow 252) (preferably rail 112 and / or slide 113) configured to guide the central portion 50 and wall 420 by translation. The rail 112 or slide 113 is fixed to the part 50, while the slide 113 or rail 112 is fixed to the bottom wall 249, respectively. The guide means 251 is configured around the piston 420, preferably at least 7 mm, and more preferably at least 7 mm to 10 mm (measured relative to a plane perpendicular to the compression axis 290 of pocket 2). The pair 251 / 252 is configured not to compress the fluid. For 251 / 252, pocket 2 is not defined.

[0371] Preferably, the wall 50 of the button 250 is substantially continuous with the wall 22. The pockets 2 and 34 have internal volumes partially separated by the wall 50, and when the pressing surface 25 is pressed, the pockets 2 and 34 contract simultaneously.

[0372] Wall 22 is integral with wall 50, and wall 50 itself is integral with movable wall 420 and rails 112 and / or slides 113, the movable wall 420 is configured to translate, and its translational motion is guided by means 251 cooperating with fixed elements 252 and / or hollows 252, preferably pairs of rails 112 and / or slides 113, each rail 112 and / or slide 113 is configured to guide the pressing surface 25. The central wall 50, deformable wall 22, piston 420, and guide means 251 (or wall 251) are preferably made of a material having a flexural modulus of at least 300 MPa, and more preferably at least 500 MPa and less than 14,000 MPa (megapascals), and are made as a single, seamless piece of material.

[0373] On average, the added thickness of wall 50 is preferably at least twice the thickness of components 51 and / or 52 of wall 22.

[0374] The portion of the wall 22 forming the slope 50 is at least 1.5 times, and even 2 times, wider (according to a measurement axis parallel or substantially parallel to the bottom wall 21) or (in measurements on a plane perpendicular to the compression axis 290 of the pocket 2).

[0375] Referring to Figures 70b and 70c, which are variations of Figure 70a, part 50 is substantially parallel to the bottom wall 21, part 51 is absent or barely present, part 52 occupies at least 70% of the wall 22, and furthermore, the entire wall 22 forms a substantially 90° angle with respect to the bottom wall 21 (substantially 90° with respect to a plane perpendicular to the compression axis 290 of the pocket 2). Part 52 (button or side of the wall 22) comprises, at least partially, an elastomer material that is more flexible than part 50. Parts 52 and 50 of the wall 22 are manufactured as a single piece by overmolding or overmolding or bi-injection molding. Referring to Figure 70b, the wall 22 and the distribution part 23 are manufactured as a single piece called the body 246. The bottom part 245, which includes the bottom wall 21, closes the pocket 2 by preferably welding or joining with the body 246. The bottom part 245 does not have fastening means for securing it to the reservoir 89 (or end piece 89).

[0376] The elastic pocket 255 and the deformable wall 22 of pocket 2 are at least partially formed by a foldable wall 301 (preferably forming a closed curve) comprising strips or assemblies of parts 146, 147 (preferably in a continuous alternating configuration of parts 146 and 147). Part 146 is configured to deform or even buckle in response to the force applied to the pressing surface 25. Part 147 is preferably formed of an elastic (more flexible than strips or part 146) flexible material and / or has an opening or fluid passage that allows fluid to pass between the internal volume of pocket 2 and the reservoir 6.

[0377] During buckling or sudden deformation of part 146, each strip or part 147 expands as follows: - The space L2 between the two strips 146 after buckling (or sudden deformation) is larger than the space L1 between the two strips 146 before buckling, and / or - The circumference of a closed curve after buckling (or sudden deformation) is greater than the circumference of the closed curve before buckling (or deformation).

[0378] Strip 146 preferably forms an elastic tongue made of a rigid or semi-rigid material (e.g., polypropylene with a flexural modulus between 500 MPa and 1200 MPa) that generates a threshold force up to buckling (or sudden deformation) of part 146, making it resistant to compressive forces in direction 140, while strip 147 is preferably made of an elastomer (e.g., TPO with a flexural modulus between 10 MPa and 80 MPa). Part 147 is configured to form an additional return mechanism in addition to the return mechanism specific to part 146 (for returning to a resting position after the compressive force 140 against the wall 25 is removed). Part 147 is configured to reduce the lateral stress of strip 146 (at the level of L2 in a plane perpendicular to the compression axis 290 of pocket 2) while avoiding deformation exceeding the elastic limit of the material, absorbing most of the lateral deformation L2 minus L1. Preferably, the strip or component 147 is wider than the strip or component 146, and these strips or components 146, 147 are manufactured integrally with the central portion 50 by overmolding or bi-injection molding, and the strip or component 146 is made of the same material as the central portion 50. The strip or tongue 146 extends over the height of the cylinder, forming an angle of less than 30 degrees with respect to the axis 290. Preferably, the wall 301 substantially forms the cylinder generated by the strip 146.

[0379] The button 250 has a foldable wall 301 or wall 22 on its side that surrounds the movable wall 420, and a guide means 251 between the movable wall 420 and the foldable wall 301. Preferably, the wall 22 or 301 has at least three strips or tongues 146 that form an angle of less than 30 degrees with respect to the axis 290, and at least two flexible parts 147 between two tongues 146.

[0380] In a modified example relating to Figure 70b, referring to Figure 70d, the foldable wall 301 defines part of the pocket 2, and the wall 50 has guide means 251 surrounding the foldable or deformable wall 22. The button 250 has a foldable wall 301 or deformable wall 22 in its central portion and guide means 251 outside the foldable wall. Note that the wall 301 is sealed, and parts 146 and 147 completely surround the pocket 2, with part 147 not containing a passage and comprising flexible material (flexible part 147).

[0381] The button 250 has a foldable wall 301 or a deformable wall 22 in its central portion, and guide means 251 at the ends of the wall 50 (forming a skirt) surrounding the foldable wall 301 or deformable wall 22. Note that the guide means 251 has a single guide wall forming a cylinder with rails and / or slides formed by slots inside or outside the cylinder.

[0382] Pocket 2 is partially defined by a foldable wall 301 or a deformable wall 22 configured to close or occupy the supply opening 41. The movable or deformable wall 22 preferably comprises a flexible component 435 obtained by overmolding or bi-injection molding on a component 146, the component 146 being more rigid than the component 435 which is made of the same material as the flexible component 147, and the flexible component 435 is located within pocket 2 and positioned toward the bottom wall. The component 435 is not movable relative to the wall 22 (except for material compression) and is positioned on a portion of the wall 22, or on a component 50, a guide means 251, or even on a portion integral with the wall 22. The component 435 is configured to transmit the pressing force 140 to the flexible component 435 by pressing the bottom wall or a component fixed to the bottom wall while the pressing force 140 acts on the pressing surface 25 from outside pocket 2. It should be noted that the fluid passes through an opening 41 formed in the bottom wall and / or through a variable opening 41 configured between wall 22 and bottom wall 21, which is more precisely provided with a flexible edge 426 around wall 22 on the side of the bottom wall, which in the closed position is configured to press against or fit against bottom wall 21, preventing or limiting the passage of fluid from pocket 2 to reservoir 6 and / or component 34. In the open position, wall 22 is configured to move away from bottom wall 21 so that the fluid can enter pocket 2 (this open position is obtained when the pressure on the pressing wall 25 is released, in particular when component 426 and bottom wall are not completely sealed to avoid an suction effect). Wall 22 with the edge 426 forms a valve 4. In the case of an opening 41 formed in the bottom wall (which can be combined with a variable opening between walls 22 and 21), when there is pressure 140 on the pressing surface 25, the flexible component 425 closes the fluid passage from pocket 2 to component 34 or reservoir 6; when the pressure 140 is released, the device is configured so that component 425 can separate from wall 21, which is done, for example, by providing a slight recess in the flexible component 425 to break the seal between walls 22 and 21.

[0383] In a modified example relating to Figure 70a, referring to Figures 70e to 70h, a wall 51 is present but a wall 52 is absent, and the wall 51 forms an angle greater than 35° with respect to the elongation plane of the device. Preferably, the device has a side wall 22 that forms a single incline 51 that averages greater than 35°, or greater than 40°, or even greater than 45° (measured on a plane perpendicular to the compression axis 290 of the pocket 2). The button 250 or deformable wall 22 is not welded to the bottom wall 249 but is simply pressed against the bottom wall, which is provided with locking means 243 to prevent the wall 22 from sliding laterally. The button 250 is clipped to bottom components 289 or 245. Preferably, the guide means 251 has at least one clip 247 for clipping to elements 252 (fixed elements and / or hollow elements of the bottom wall), more precisely, the rail 112 or the slide 113 of the button is clipped to the slide 113 or the rail 112 of the bottom wall, respectively. The button 250 of part 50 has a hole 256 for forming a clip 247, and the bottom wall 249 has a hole 256 for forming a locking portion 248. The device is equipped with an indexing means 244 for positioning the button 250. In the resting position, the valve 4 is open, and the opening is formed by the space formed 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 space between the end of the piston 420a and the cylinder 430a in the resting position) is at least 120° with respect to the axis of the piston 420. The opening 428 is preferably at least 1 mm², preferably at least 2 mm². The opening 428 extends along the axis of the reservoir 6, and when the device is filled with a non-viscous fluid such as water in the direction 87a corresponding to the extension of the reservoir, a portion of the opening 428 is in contact with the fluid, while the other portion of the opening 428 is in communication with the outside of the device, allowing water to enter the pocket 2. As shown in International Publication No. 2019002527, the device includes a step of filling at least a portion of pocket 2 while it is open and in communication with the outside of the device.

[0384] Referring to Figures 70g and 70h, the width 54a of the central wall 50 is preferably greater than 0.25 times, more preferably greater than 0.30 times, and more preferably greater than 0.40 times, the width 54b of the wall 22 (measured in a plane perpendicular to the compression axis 290 of the pocket 2, excluding the ends of the wall 22 pressed against the bottom wall). Referring to Figure 70h, the width 54a of the central wall 50 is preferably greater than 0.3 times, more preferably greater than 0.4 times, and more preferably greater than 0.5 times, the width 54c of the wall 22 that corresponds only to the moving or deforming width (measured in a plane perpendicular to the compression axis 290 of the pocket 2).

[0385] Next, with reference to Figure 70i, an embodiment 20000 of the device according to the present invention will be described. This embodiment will only describe the differences from the embodiment shown in Figure 70b.

[0386] Parts 146 and 147 are visible from the outside of the device. The pocket 34 surrounding pocket 2 (between the foldable wall 301 and the piston 420 / cylinder 430 pair) preferably contains air and does not have a fluid inlet opening 163.

[0387] Component 147 is formed of a flexible material and / or an air passage. Components 146, 147 (completely or partially) surround the sealing piston 420 and the conduit or cylinder 430 that defines the internal volume of pocket 2. The cap 70 has a shoulder 302 at its base that extends outward from the device. The cap 70 is superimposed on a foldable wall 301 at the position of the shoulder 302. The strip or components 146, 147 are substantially parallel to the extension axis of the device and / or the axis of the cap 70 and are manufactured integrally with the cap 70 by overmolding or bi-injection molding. In a variation not shown in Figure 70d, the piston 420 / cylinder 430 is replaced by a foldable wall 301, the foldable wall is inside the cap 70, and the guiding means is integral with the wall 302 of the cap 70.

[0388] Next, embodiments of the device 21000 according to the present invention will be described with reference to Figures 71 to 73a. Unless otherwise specified, these embodiments will only describe the differences from the embodiment shown in Figure 70a.

[0389] In this embodiment, pocket 2 is located outside the reservoir, and the pressing surface 25 has a central wall 50. In this embodiment, the movable wall 420 does not define at least a portion of the internal volume of pocket 2.

[0390] In this embodiment, the deformable wall 22 defines at least partially the internal volume of pocket 2. The elastic pocket 255 coincides with pocket 21, and the bottom wall 249 coincides with bottom wall 21 (for device 19000, in this description, pocket 255 may be replaced with pocket 2, and bottom wall 249 may be replaced with bottom wall 21). There are no pistons 420 and cylinders 430 forming pocket 2, and the fluid reaches pocket 2 directly through the membrane of the intake valve 4 without passing through the intermediate pocket 34.

[0391] In this embodiment, the wall 22 is configured to press the valve 4 directly or indirectly, more precisely, the wall 22 has a component 53 around it which transmits at least partially to the supply valve 4 while a pressing force 140 is applied to the pressing wall 22 from outside the pocket, and the transmission is configured to be transmitted directly to the supply valve 4 or to the supply valve 4 via a pressing member 139 of the supply valve as shown in Figure 73a, the pressing member 139 having a tongue 138 which is configured to press the supply valve 4, more precisely, to press the supply valve 4 against the bottom wall component 21 by pressing the valve membrane. When the wall 25 is pressed, the component 53 of the wall 22 is configured to deform before the other parts of the deformable wall 22 deform, more precisely, before the sudden deformation of walls 51 and 52. The wall 50 of the button 250 is configured to translate toward the bottom wall, guided by a rail / slide pair. The pressing member 139 of the supply valve 4 is integral with a part of the bottom wall 21. The member 139 belongs to the same component as the bottom wall 21 and is obtained by molding the bottom wall 21 and the cavity 8 of the distribution valve.

[0392] The supply valve 4 (more precisely, on its membrane) is equipped with a bubble or bump 135 (connected to a pin 139 to apply more central force) which can contact the bottom wall 21 by forming a spring.

[0393] The part 50, which is integral with the wall 22 forming the slope 50, has a width 54a (measured along a measuring axis parallel or substantially parallel to the bottom wall 21, or on a plane perpendicular to the compression axis 290 of the pocket 2), which on average is equal to at least 0.3 times, and even more than 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 an axis parallel or substantially parallel to the wall 21). The width 54a of the central wall 50 is greater than 0.4 times, and even more than 0.5 times, the width 54c, which corresponds only to the portion of the wall 22 that moves or deforms toward the wall along the pressing axis 140 (measured on a plane perpendicular to the compression axis 290 of the pocket).

[0394] Referring to Figure 73, the device has a reinforcing member 131 of the wall 50 that is integrated with at least two guide walls 251.

[0395] The wall 22 and / or bottom wall 22 are provided with a skirt 155 that has a height at least the same as the height of the entrance to the pocket-side cavity 8 in the same measurement direction (i.e., a minimum of 1.5 mm or 3 mm).

[0396] The skirt 155 allows the valve 5 to be inserted into the cavity 8 from inside the pocket 2 or outlet 24 which is perpendicular or substantially perpendicular to the direction in which the height of the skirt 155 is measured. Thanks to the skirt 155, the bottom wall 21 takes the form of a flat or substantially flat surface 156, facilitating the welding of the bottom wall 21 to the surface 56 of the flexible bag 14 that forms the reservoir 6.

[0397] The bag 14 is an open film before being welded to the wall 21, and is folded (along the fold 144) to form the internal space of the reservoir 6, closing itself, with the outlet 24 oriented laterally and the distribution spout 30 oriented laterally. The distribution spout 30 protrudes less than 3 mm, and even less than 1 mm, from the edge of the formed bag 14.

[0398] In another modified example, referring to Figure 72, part 53 comprises a flexible part 435 which may or may not be arranged around the deformable wall 22, and the deformable wall is configured such that at least a portion of the pressing force 140 acting on the pressing surface 25 from outside the pocket 2 is transmitted to the flexible part 435. Features of device 19000 can be combined with features of device 21000, and in particular, pocket 2 may comprise a series of alternating parts 146 and 147.

[0399] It should be noted that a portion of the wall 22 forms a recess 57 surrounding the movable part of the wall 22, so that the force 140 is more properly concentrated in the center, the movable part of the wall 22 is protected, and the thickness of the device is thinner when the same dose is distributed. It should be noted that the deformable wall 22 forming the recess 57 is located on the opposite side of the opening of the valve cavity 8. There is a straight line that passes through the cavity 8 of the distribution valve and crosses the deformable wall 22 three or four times.

[0400] Referring to Figures 74, 75, and 76, each of the above embodiments or modifications, comprising a deformable wall 22 (preferably defining at least a portion of the internal volume of pocket 2), which is not located inside reservoir 6, may also include a button 162 having threads 164, which may preferably be screwed to an element integral with wall 22, located at the top of the concave shape of wall 22 (for example, when a cap 70 is located at the top of wall 22 (examples in Figures 4, 13, 14, 16, 18, 23, 24, 30, 32, 34, 35, 40, 45, 69, and 75), or when an additional rod or support 166 having threads is located at the top of wall 22 (examples in Figures 19, 38, 56, 58, 72, and 74).

[0401] The threads 164 are configured to adjust the spacing between the plug 162 and the bottom wall 21 or another part of the device according to the present invention, in accordance with the screwing of the plug 162 into the wall 22, or generally to adjust the maximum possible amplitude 165 of movement of the button 162 on the wall 22, and thus adjust the maximum amount or product dispensed by the outlet 24 of the device according to the present invention when the button 162 is pressed (thus adjusting various compression states of the pocket 2 by the button 162).

[0402] The pressing surface 25 may be at least partially located on the button 162 and / or on the cap 70 (which may protrude from or pass through the button 162) and / or on the support 166 (which may protrude from or pass through the button 162).

[0403] The device according to the present invention may also include sensing notches 167b and / or dispensing notches 167a (between the button 162 and another part of the device, such as the crown 158 surrounding the pocket 2 and in contact with the button 162), which are configured to block different screw-in positions of the button 162 on an element 70 or 166 fixed to the wall 22, and thus block different compression states of the pocket 2 by the button 162. The crown 158 has a groove on its inner surface configured to cooperate with at least one tongue 159b of the button 162, and a recess on its outer surface configured to cooperate with at least one bump or wall 159a integral with the side wall of the button 162. The recess indicates a meter marking on the wall of the device, more specifically on the bottom wall 21. The device is configured such that the rotation of the button between the minimum and maximum metering positions is less than 360°. At the maximum dosage position, the button is configured so that the screw does not come loose, for example, when a finger on the bottom wall comes into contact with the tongue piece 159b. Referring to Figure 74, the support 166 is configured to fit into the bottom wall 21 on the supply valve 4 side, and the screw 164 is inside the support.

[0404] Referring to Figure 76, it can be seen that the recesses are not regularly arranged on the crown, reflecting the nonlinear deformation of the pocket. Note that this device can be purged and cleaned at the position of button 162, which provides a large displacement of pocket 2, thereby avoiding device shutdown and enabling low-usage distribution.

[0405] In the method according to the present invention for all embodiments of the device according to the present invention described above, - When reservoir 6 or the product to be distributed is filled, and reservoir 6 is filled or produced, the opening 87 is closed, and then, - Referring to Figure 68a, the device 580 according to the present invention is positioned with its head facing upward (i.e., the pocket 2 is located above at least a portion of the reservoir 6 (relative to Earth's gravity)) within the housing 500, under vacuum (preferably under reduced pressure of at least 0.5 bar per atmosphere), so that air can exit the device according to the present invention, for example, through the distribution valve 5 (vacuum is performed by the suction means 526), ​​and thereafter, - In a vacuum within the housing (preferably under reduced pressure of at least 0.3 bar, and even more precisely 0.5 bar, relative to 1 atmosphere), the device according to the present invention is tilted (typically by tilting the support 501) to a new position tilted at least 30°, and even more precisely 90° (preferably 180°) from the vertical, and, - Referring to Figure 68b, while the device according to the present invention is in this new position and / or while the device according to the present invention is tilted in this new position, the pressure inside the housing is increased (preferably to 1 atmosphere, usually by introducing air from the air inlet 525).

[0406] This method for priming a device according to the present invention is carried out by a system comprising the following: - Housing, which is configured to house the device according to the present invention in an initial position with the head facing upward (preferably, the outlet is located above (relative to gravity) at least a portion of the reservoir), - Vacuum means, which sets the housing under vacuum (preferably at least 0.3 bar, and even more precisely 0.5 bar, per atmosphere) so that air exits the device according to the present invention (for example, by its distribution valve), the vacuum means preferably comprises suction means. - A tilting means, which sets a device according to the present invention, disposed within a housing, to a new position by tilting it at least 30°, more preferably at least 90° (preferably 180°), with respect to the vertical (or initial position). This tilting means typically comprises means for tilting the housing, or a support configured within the housing. - Means for increasing the pressure inside the enclosure (usually including means for introducing air into the enclosure via an air inlet).

[0408] The distribution channel 114 includes means 136 configured to press the joining element 115 against the inner wall of the distribution channel.

[0409] This means 136 typically comprises at least one element (such as a tooth or fence) which emerges from the inner wall of the distribution channel and is inserted into the recess 137 of the joint element so as to press the two parts of the joint element from the inside of the joint, the two parts of the joint element being in two opposite directions but both facing at least one of the inner walls of the distribution channel.

[0410] A stud 117 is attached to the end of the membrane 116 (the end of the membrane 116 opposite to the end that connects to the joining element 115). This stud 117 is inserted into the portion comprising the nozzle 59 and the arm 132.

[0411] The stud 117 and nozzle 59 are configured to leave between them at least one channel configured to generate vortices in the fluid being distributed. The arm 132 is configured to push the valve 5 into the channel 114 when the nozzle 59 is inserted into the channel 114.

[0413] In this device 22000, the movable or deformable wall 22 is not located within the reservoir but is superimposed on the reservoir 6. The bottom wall 21 is substantially horizontal. Vertical and horizontal are not defined with respect to the direction of Earth's gravity. The terms vertical and horizontal are conventionally chosen as two orthogonal directions. The wall 22 is preferably a deformable wall, but may be a movable wall.

Preferably, the reservoir comprises a layer 360, which is on the outside and harder than the inner layer 352, and is made of cardboard or cellulose material or the like.

[0420] It should be noted that the skirt may include a bent return wall or side wall 352 that forms a contact point with the insertion of the bottom component 289 (for welding or bonding work) from the inside of the reservoir 6.

[0421] According to another aspect of the present invention, a method has been proposed for manufacturing a device comprising a reservoir for distributing fluid, a bottom component, and a cap having a plug, in which, - In the first step of manufacturing the device, the bottom component is bonded or welded to the reservoir (skirt 148 and / or bent return 361) by inserting the bottom component from the inside of the reservoir (the part of the reservoir without a bottom or base), - In the second step of manufacturing the device, the reservoir 6 is closed by gluing or welding the bottom of the reservoir, which has a bottom component on top. - In the third step, the reservoir is filled through the filling holes 87 and 87b. - In the fourth step, at least one filling opening 87 of the bottom component is closed by at least one plug 310, cap 70.

[0422] The reservoir wall 118 is fixed between the skirt 148 and / or the bent return 361 and the cap 70.

[0423] Preferably, the outlet opening 24 is elongated to take the form of a channel 189 inside the spout 30, which is part of the cap 70, and the opening 24 is adjacent to, preferably in contact with, the cap opening 188 and connected to the cap opening 188. The channel 189 connects the distribution opening 24 to the cap opening 188 by crossing the skirt 149, and the outlet 24 passes through the skirt 149. The outlet 24 and / or channel 189 are lateral.

[0424] The outlet opening 24 is configured to allow fluid to flow laterally, and channels 114 and 189 have substantially the same lateral orientation. The distribution conduit 114 connects the distribution opening 355 to the outlet opening 24. The distribution conduit 114 and the bottom wall 21 are formed in the bottom component 289 and lead to the opening 340.

[0425] The device 22000 is equipped with a supply opening 41 which is configured to pass vertically through the bottom component 289 (more precisely through the wall 21) and allow the fluid to pass into the interior of the pocket 2.

[0426] The device 22000 is equipped with a distribution opening 355 which passes vertically through the bottom component (more precisely through the wall 21) and is configured to discharge the fluid from inside the pocket, preferably into at least the distribution conduit 114.

[0427] The distribution valve 5 is configured to allow fluid in the pocket 2 to flow out through the distribution opening 355 when it is open, and to prevent fluid in the pocket 2 from flowing out through the distribution opening 355 when it is closed.

[0428] Preferably, valves 4 and 5 form a single component via a connecting element 115. The distribution valve 5 is equipped with a so-called distribution membrane 116. The supply valve 4 is equipped with a so-called supply membrane 119.

[0429] In the closed state, the supply valve 4 (more precisely, the membrane 119) closes the opening 41 and is pressed against the bottom component 21. In the closed state of the valve 4, the membrane 119 extends along the extension of the conduit 114, i.e., horizontally or substantially horizontally.

[0430] In the open state, the supply valve 4 (more precisely, the membrane 119) does not close the opening 41 and is at least partially separated from the bottom 21 (more precisely, separated from the valve seat 127) compared to its closed state.

[0431] In the closed state, the distribution valve 5 (more precisely, the membrane 116) closes the opening 355 and is pressed against the bottom component 21. When the valve 5 is closed, the membrane 116 extends horizontally or nearly horizontally.

[0432] In the open state, the distribution valve 5 (more precisely, the membrane 116) does not close the opening 355 and is at least partially separated from the bottom 21 compared to its closed state.

[0433] The supply valve 4 is fixed to the wall 21 by a connecting element 115. The distribution valve is fixed to the bottom wall by a connecting element 115. The intake valve 4 and / or distribution valve 5 are independent and removable.

[0434] The intake valve 4, more precisely the membrane 119, is not part of the cap (it is not part of the cap) and is not manufactured or injection molded together with the cap 70 or bottom part 289, and there is no material continuity between the intake valve 4 and the cap 70 or bottom part 289. The distribution valve 5 or its valve seat is not part of the cap and is not manufactured or injection molded together with the cap or bottom part 289, and there is no material continuity between the distribution valve 5 and the cap 70 or bottom part 289. The bottom wall is fixed, and the bottom wall 21 is not movable relative to the skirt 148.

[0435] Device 22000 may further include the following: - (In the "atmospheric" version) A tube, which enters the reservoir and forms a supply conduit (vertical or nearly vertical) configured to guide the fluid from reservoir 6 to supply valve 4, which may be part of bottom component 289 or a separate component. - (In the "airless" version) A piston, which rises within reservoir 6, or a flexible bag, which collapses as the fluid is drawn from reservoir 6.

[0436] The device is equipped with means to facilitate priming, the first of which is a protective element 126 in the cavity 134 of the bottom wall 21, as shown in Figures 79 to 83, and more precisely, protects the sensitive portion 370 (around the movable part of the valve 4) around the supply opening 41.

[0437] The element 126 of the bottom wall 21 partially covers the valve 4 with respect to a direction 140 perpendicular to the bottom wall 21, and preferably operates in such a way that when the surface 25 is pressed along this direction 140, the valve 4 is not lifted by the overpressure effect within the pocket 2 during the compression phase of the pocket 2, or the lifting of the valve 4 is limited.

[0438] At least a portion of the movable perimeter 370 of the supply membrane 119 is inserted into the cavity 134 (370 refers only to the movable portion of the membrane 119 during the product pumping operation).

[0439] More precisely, - Two opposing lateral movable edges 371, 372 in the supply film 4, and - The front movable edge 376 of the supply membrane 119 forms a joint between the two lateral movable edges 371 and 372, and these edges are inserted, at least partially, into the cavity 134. The front movable edge 376 is further from the joint element 115 than the movable edges 371 and 372.

[0440] Preferably, at least 50% of the movable perimeter (371, 372, 376) is housed in the cavity 134, more precisely between the feed seat 127 and the element 126. Note that the perimeter 370 tapers to connect with the feed seat 127. The feed film 119 has a thickness that thins towards at least a portion of the perimeter of the feed film (371, 372, 373).

[0441] Another means of facilitating the priming of the device consists of one or more bumps 350 on the periphery of the bottom wall, which may be discontinuous or not (e.g., four bumps if the pocket is square), and which are distributed along the periphery of the bottom wall 21 except for the center. Referring to Figure 80, which shows the compressed state of the movable or deformable wall 22 (i.e., the central portion of the wall 22 pressed against the bottom wall 21), at least one bump 350 is configured to fit into a bend or deformation 190 formed around the periphery of the wall 22. The air remaining in the pocket 2 (in a compressed state) is reduced by at least 20%, and even more than at least 40%, compared to the case of a substantially flat bottom wall without bumps 350. Preferably, the height of these bumps is at least 1 mm, and even more than at least 2 mm, outward from the center of the bottom wall. The bottom wall has one or more bumps configured to reduce the volume of air in the pocket during compression of the pocket in priming the device.

[0442] Referring to Figure 85 in this modified example of device 22000, the movable or deformable wall 22 is configured to push the supply valve 4 directly or indirectly, and more precisely, the movable or deformable wall 22 has parts 53 or pins around it. 1 It has 98 (or rigid parts), and its part 53 or pin 1 98 (or rigid component) is configured to transmit, at least partially, the pressing force 140 acting on the pressing surface 25 from outside the pocket 2, directly or indirectly, to the supply valve 4, using or via the pressing member 139 (more precisely, a pin or rigid component 198 and / or tongue 138, as shown in the modified example in Figure 73a and Figure 85), the pressing member 139 of the supply valve 4 is configured to close the valve 4 by pressing the supply valve 4 (by pressing the supply valve 4, the membrane 119 is pressed against the valve seat 127).

[0443] Referring to Figures 72 and 85, the part 53 or pin 198 (or rigid part) of pocket 22 directly connects the valve 4, or more precisely, the bubble 135 of the membrane 119 of the supply valve 4. contact The valve 4 is then configured to close (by pressing the supply valve 4, the membrane 119 is pressed against the valve seat 127).

[0444] This prevents air from passing through the opening 41, facilitating priming. The wall 22 or the component 53 of the pressing member 139 or the pin 198 (or rigid component) contacts the valve 4.

[0445] The tongue 138 extends horizontally within the supply opening 41. The pressing member 139 of the supply valve 4 is integral with the bottom part 289 (more precisely, integral with the bottom wall 21), but not with the pressing surface 25. Member 139 belongs to the same part as the bottom wall 21. Member 139 is obtained from the molded parts of the bottom wall 21 and the channel 114, and the pin 198 of member 139 is preferably vertical and extends from the bottom part, more precisely from the tongue 138.

[0446] Referring to Figures 84 and 85, the movable or deformable wall 22 is configured to push the valve 5 directly or indirectly, and more precisely, the movable or deformable wall 22 is configured around or in the center of the component 153 or pin 3 9 It has 8, and its part 153 or pin 3 9 8 is pressed from outside pocket 2, which is partially defined by a movable or deformable wall. surface While the pressing force 140 is acting on 25, the pressing force 140 is transmitted, at least partially, to the valve 5, more precisely, by directly transmitting it to the valve 5, or to the membrane 116, or Figure 86As shown, the valve 5 is configured to be pushed and opened by a pressing member 339 of the valve 5, which is configured to push the valve 5 and open the valve 5 by a tongue 338 and / or pin 398, thereby helping air to pass through the opening 355 and promoting priming. The parts 153 of the wall 22 or the pin 398 or the pressing member 339 contact the valve 5 and push the membrane 116, more precisely, move the distribution valve 5 away from the bottom part 289 (more precisely, move the distribution valve away from the bottom wall 21).

[0447] The pressing member 339 of the distribution valve 5 is integral with the bottom component 289 (more precisely, integral with the bottom wall 21 and molded together with the pins that form the channel 114).

[0448] During compression of pocket 2, the pressing member 339 of the distribution valve 5 is configured to move later than the pressing member 139 of the set intake valve while a pressing force 140 is applied to the compression wall 25 from outside pocket 2. The pressing member 139 of the intake valve is configured to move within the inlet opening 41, and the pressing member 339 of the distribution valve is configured to move within the distribution opening 355.

[0449] It should be noted that the wall 21 is provided with a tongue piece 138 that extends (preferably horizontally) into the supply opening 41. The wall 21 is provided with a tongue piece 338 that extends (preferably horizontally) into the distribution opening 355.

[0450] Referring to Figure 84, while the pressing surface 25 is fully pressed from a stationary state, the pressing member of the distribution valve 5 presses after the pocket 2 is compressed by 70%, while the pressing member of the supply valve 4 presses the supply valve before the pocket 2 is compressed by 30%, or before the upper part of the wall 22 deforms by 2 mm.

[0451] The pressing wall 25 has a recess or component 254 of a movable or deformable wall 22 on the pocket 2 side, which is surrounded by a flexible edge 253 of the movable or deformable wall 22 and surrounded by the pressing surface 25, the edge 253 comprising component 53 and / or component 153, which preferably are positioned on the edge 253 to form a flexible component of at least 180° and even at least 360° around the pressing surface or compression axis 290 (which is near the center of the bottom wall and perpendicular to the bottom wall 21).

[0452] The component 254 of wall 22 forms a joint line 293 (preferably forming a circle) between the edge 253 and wall 22, and this joint line 293 of wall 22 does not rest on wall 21, and the edge 253 is cantilevered and rests on the periphery of the bottom wall 21 and / or on the skirt 148 (facing the periphery of pocket 2) which forms a support line 292 of the flexible edge 253. The flexible edge 253 is between the joint line 293 and the support line 292 and has a width of at least 3 mm, more preferably at least 4 mm, and more preferably at least 5 mm (measured in a plane perpendicular to the axis 140).

[0453] While the pressing surface is pressed 140, the flexible edge 253 surrounds the pressing surface or the part 254 and deforms toward the bottom wall at the position of the joint line 293, preferably the entire joint line 293 moves substantially parallel to the bottom wall 21 (or at an angle of less than 20° relative to the bottom wall 21), and these deformations and movements preferably occur at the start of compression of pocket 2, before 10% compression of pocket 2 (from the initial volume of pocket 2), or before at least 30% compression (from the initial volume of pocket 2), or before at least 50% compression (from the initial volume of pocket 2) (compression is along the compression axis 290 at the center of pocket 2). The flexible edge 253 comprises parts 53 and / or 153 and deforms toward the bottom wall by at least 0.1 mm, and moreover 0.3 mm (at least at the positions of parts 53 and / or part 153), and this deformation occurs before 10% compression of pocket 2 (from the initial volume of pocket 2) or before 50% compression of pocket 2 (from the initial volume of pocket 2) (compression is compression along the compression axis 290 at the center of pocket 2). Preferably, the entire edge 253 moves toward the bottom wall by at least 0.2 mm, and moreover 0.4 mm (moreover 0.8 mm if the edge 253 contains flexible material), and this movement occurs at the position of the joint line 293 before 30% compression of pocket 2.

[0454] Note that pins 198 and 398, which are fixed to parts 53 and 153 respectively, move toward the bottom wall by the same distance as parts 53 and 153.

[0455] Referring to Figures 85 and 86, the device comprises two pressing means 53 and 153. When the device is pressed from a stationary state, the pressing of the intake valve 4 by part 53 (directly or indirectly) preferably begins before the pressing of the distribution valve 5 by part 153. The pressing of the intake valve 4 by part 53 preferably occurs before 30% compression of pocket 2 (from its initial volume), and the pressing of the distribution valve preferably occurs after 50% compression of pocket 2 (from its initial volume).

[0456] The edge portion 253 is preferably substantially planar and parallel to the bottom wall, or forms an angle of less than 20° with the bottom wall. The pressing wall or pressing surface 25 includes a deformable or movable wall 22. The surface 253 may have flat portions and / or one or more recesses and / or bumps to create a more flexible (and deformable) zone, to increase the stroke toward the valves 4 and / or 5 and to increase the displacement. The parts 53 and 253 are, on average, thinner than the part 254, or the portion 253 is made of a more flexible material than the part 254, and is at least more flexible than a portion of the pressing surface 25, preferably more flexible than the top of the pocket 2.

[0457] Referring to Figure 85a, in a modified example, the movable or deformable wall 22 is configured to directly or indirectly press a supply valve 4 which includes a flexible component 435, the flexible component 435 of which is preferably obtained by overmolding or bi-injection molding (or, if made of elastomer, from the same material as the flexible edge 253), and which is fixed to the flexible edge 253 within the pocket 2 and positioned toward the bottom wall. The flexible component 435 is coincident with the valve 4 and is not movable relative to the wall 22. The component 435 is configured to transmit, at least partially, this pressure 140 to the flexible component 435 in order to seal or close the supply opening by pressing against the bottom wall or a portion integral with the bottom wall while a pressing force 140 is acting on the pressing surface 25 from outside the pocket 2. The pressing component 53 or rigid component 198 includes the flexible component 435 and forms the valve 4.

[0458] Parts 53, 153, pin 198, 398, and flexible part 435 (valve 4) are all integral with the edge 253. The edge 253 is configured to at least partially transmit the pressing force 140 to the supply valve 4, pressing the valve 4 against the bottom wall, and / or at least partially transmit the pressing force 140 to the distribution valve 5, pushing the distribution valve away from the bottom wall 21, more precisely, the membrane 116 of the distribution valve 5 away from the distribution seat of the valve 5 formed in the bottom wall 21.

[0459] All aspects of the various modifications that facilitate priming, in particular the pressures on the bump 350, protective element 126, intake valve 4 and / or distribution valve 5, may be combined.

[0460] In the modified versions shown in Figures 84 and 86, the device 22000 does not have a plug 310, and the cap 70 can rotate relative to the bottom part 289. In the modified version shown in Figure 85, it can rotate 360°, but in the modified version shown in Figure 84, it cannot rotate completely because of a pin 198 that interferes with the bottom wall. In this case, a bean-shaped opening is provided in the bottom wall 21 to allow rotation.

[0461] The cap 70 rotates relative to the bottom component 289 (preferably around a vertical axis perpendicular to the wall 21, and preferably around an axis passing through the center of the wall 21) between the open and closed positions of the cap 70, so that the cap 70 (more precisely the skirt 149) prevents fluid from flowing out of the device through the distribution opening 355. The cap 70 is configured to block or stop the distribution of pocket 2 (until channel 114 is filled), with the opening 340 covered by the skirt 149 in the closed position and the opening 340 released in communication with opening 188 in the open position, opening the passage from channel 114 to channel 189.

[0462] The bottom part 289 or bottom wall 21 is clipped to the neck 85 and can rotate relative to the reservoir 6 so that the user can change its orientation. Thus, to close, the bottom part 289 holds part 195 and the cap 70 is rotated, or the cap 70 is held and the bottom part 21 rotates together with part 195. Channels 114 and 189 may rotate around the same axis or rotate slightly in opposite directions, but they remain in communication. The opening 188 of the cap 70 communicates with the opening 340 of the bottom.

[0463] Visual markers 365 and 366 allow the open and closed positions of the cap 70 to be visually distinguished from outside the device. The skirt 148 is longer than the skirt 149 and is a bottom component visible from outside the device. 2 It comprises 89 parts 195, this visible portion 195, which does not extend around the wall 21 but is equipped with notches or visual marks 366, and the skirt 149 is also equipped with notches or visual marks 365.

[0464] In this closed position, the distribution conduit 114 is not connected to either the outlet opening 24 or the opening 188, and the cap 70 (more precisely, the skirt 149) is closing off the distribution conduit 114.

[0465] Referring to Figure 82(sic), the device 22000 has two sealing ribs 341 and 342 on either side of the opening 340, more precisely, recesses and / or bumps at corresponding positions on the skirts 148 and 149. In a modified example not shown, the sealing ribs 341 are configured to rotate within grooves in the bottom wall 21, and the cap 70 has one or two sealing skirts.

[0466] In all embodiments, the reservoir may comprise an outer wall made of cardboard (more commonly made of cellulose) and an inner wall or film made of plastic.

[0467] It should be noted that in all the embodiments described above, the device is configured to operate with its distribution head facing upward (i.e., outlet 24 positioned above the reservoir 6) or downward (i.e., outlet 24 positioned below the reservoir 6) (i.e., distributing fluid through the outlet via the supply valve and / or distribution valve).
