На этой более толстой части может быть расположено множество выдачных частей 23 в случае с множеством выпускных отверстий 24 (как будет показано ниже в случае ФИГ. 37-40).It should be noted that at the junction between part 23 and wall 22, wall 22 is thicker than anywhere else, especially at its edge. In other words, wall 22 is thicker at its top than at its bottom. This provides an opportunity to expand the deformation: a slight pressure on the edges provides

wall deformation 22. Loads are less significant and this prolongs the life of the device. On this thicker portion, a plurality of protruding portions 23 may be located in the case of a plurality of outlets 24 (as will be shown below in the case of FIGS. 37-40).

[0072]

The pressure surface 25 is configured to reduce the internal volume of the chamber 2 under pressure by deforming (and moving) the deformable wall 22, moving the dispensing cavity 8 and the dispensing valve 5 towards the bottom wall 21. The direction of the liquid is opposite to the direction of pressing the device and is located exactly along center.

[0073]

By making the protruding part 23 and the deformable wall 22 in one piece, the compactness of the device and, consequently, the ease of its use and manufacture are significantly improved.

Cavity 8 extends along an axis passing through chamber 2, deformable wall 22, and bottom wall 21.

[0074]

Between the deformable wall 22 and the protruding portion 23, the material is continuous. Wall 22 and part 23 are joined in one piece of the same material without material interruption, for example PP with a hardness of 80 Shore D and/or a flexural modulus of less than 1000 MPa.

[0075]

The pressure surface 25 is configured to reduce the internal volume of the chamber 2 under pressure by deforming the deformable wall 22, more specifically, by squeezing it in the direction of the bottom wall 21. deformable wall.

[0076]

The protruding portion 23 is movable at least in translational movement by applying pressure to the pressure surface 25.

For the state of the maximum value of the inner volume of the chamber 2, the deformable wall 22 has a concave shape on the side of the inner volume of the chamber 2; for example, the shape of the dome (essentially round, square or oval, or other).

[0077]

The deformable wall 22 has a shape memory effect. When this wall 22 is not subjected to external loads, it recovers or maintains its shape (preferably concave), which increases the volume of the chamber 2.

The issuing part 23 is located outside the chamber 2.

The dispensing portion 23 is provided with a dispensing ring 28 surrounding the outlet 24.

The dispensing ring 28 is screwed onto the dispensing part 23.

[0078]

Ring 28, for example, is made of PP. The product exits on a dispensing ring 28, the distance between the valve closing means (more specifically the dispensing seat 105) and this dispensing ring being less than 6 mm.

The pressure surface 25 is partially located on the protruding part 23 (around the outlet 24) and on the outer surface of the ring 28.

[0079]

The minimum surface area of this pressure surface 25, accessible from the outside of the device 101 for the user's hand, is 20 mm ² .

The dispensing cavity 8 comprises a small opening 224 (or small cavity 61) of the dispensing cavity 8 on the side of the outlet 24 and a large opening 205 (or a large cavity 62) of the dispensing cavity 8 on the side of the dispensing opening 108, the former having a smaller area (or volume), than the last one.

[0080]

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

The area of the small opening 224 (or relatively small cavity 61) of the dispensing cavity 8 on the side of the outlet 24 is at least twice the area of the large opening 205 of the dispensing cavity 8 on the side of the dispensing opening 108.

[0081]

The channel between the large opening 205 (or large cavity 62) and the small opening 224 (or small cavity 61) is typically formed by a shoulder or member 29 of the filling cavity 8. It should be noted that this ledge 29 in the dispensing channel is connected to the outlet 24 and is located downstream of the dispensing valve 5 (as opposed to the valve stem, the reduction in cross section before closing the valve).

[0082]

The filling element 29 is usually a valve seal 5 with a gap of 0-0.5 mm, possibly less than the cylindrical channel connecting the outlet and the outlet of the cavity (cylinder).

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

[0083]

Such a channel, in particular, provides the possibility of limiting the inactive volumes of fluid in the cavity and at the outlet 24, as well as improving hygiene.

The dispensing valve 5 includes a portion 11 held between the inner walls of the cavity 8 at a large opening 205.

[0084]

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

Tube 18 allows fluid to pass between portion 11 and the interior walls of cavity 8 at large opening 205 (or large cavity 62, respectively).

[0085]

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

The tube 18 is provided with a stop 327 on the dispensing seat 105, this stop 327 being configured to compress the dispensing valve, more specifically the movable portion of the membrane 12 of the valve 5.

[0086]

The tube 18 extends along the cavity 8 in the same longitudinal direction. Tube 18 and cavity 8 have the same longitudinal direction.

The tube 18 forms a groove formed in the protruding part 23 from the cavity 8.

This part 12 is a membrane or plate.

[0087]

The dispensing valve 5 includes a portion 12 inserted into a small opening 224 (or into a small cavity 61). This part 12 is the movable membrane 12 of the valve 5. Part 12 is located in a small cavity 61, and part 11 is located in a large cavity 62.

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

[0088]

The channel between the large opening 205 (or large cavity 62) and the small opening 224 (or small cavity 61) further simplifies the installation of the valve 5 in the cavity 8 by means of a "rear" mounting, i. by pushing the hard part 11 rather than "front" by pushing the membrane or plate 12, which is movable and fragile.

[0089]

It should also be noted that the dispensing seat 105 is a side portion of the inner walls of the cavity 8, i. e. the seat 105 is limited to one side, preferably flat (or curved), by the inner walls of the cavity 8, and does not pass around a section of the cavity 8, which is made in a plane perpendicular to the longitudinal direction of the section of the cavity 8 containing the valve 5. The cavity 8 has a groove 88 of the channel, issuing the seat partially surrounds this groove 88, part 11 closes the groove 88 to form a sealed channel.

[0090]

The device 101 includes a supply tube 6 coinciding (as shown in the figures) or connected to the reservoir 13 of the fluid.

The tube 6 and/or reservoir 13 is at least partially delimited by a flexible wall 14 or a flexible casing 14, typically of a polyethylene terephthalate (PET)/aluminum/molded polypropylene (PP) multilayer film, with the PET layer on the outside of the casing 14.

The device 101 includes a supply opening 124 connecting the supply tube 6 to the interior of the volume of the chamber 2.

[0091]

The device 101 includes a supply valve 4 which, when open, allows fluid from the supply tube 6 to pass towards the inside of the chamber 2 through the supply opening 124, and when closed, prevents the passage of fluid from the supply tube 6 to the inside of the chamber. 2 through the feed opening 124.

The supply valve 4 is located inside the chamber 2 and is configured to:

- pressing against the feed opening 124 in its closed state, and

- moving from the feed opening 124 in its open state.

[0092]

The supply valve 4 (movable between its closed and open positions) in the closed state is held pressed against a fixed part (the so-called supply seat, which at least partially surrounds the periphery of the corresponding supply opening 124), which is also a "rigid" part (i.e., (e. not made of flexible material) of the inner wall of the chamber 2. More specifically, the supply valve 4 comprises a membrane which, in the closed state of the supply valve 4, is held pressed against the supply seat and is moved away from the supply seat in its open state.

[0093]

The feed seat is located inside chamber 2 on wall 21.

At rest, i.e. without the impact of loads or external forces on the device 101, the valve 5 is in its closed state.

Preferably, even if it is less important, at rest, ie. without loads or external forces acting on the device 101, the valve 4 is also in its closed state.

[0094]

When the chamber 2 is filled with the fluid to be dispensed and the volume of the chamber 2 is reduced (eg due to increased pressure on the pressure surface 25):

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

the supply valve 4 is pressed against the supply opening 124 and the valve 4 is in its closed state; the possibility of exit of the fluid from the chamber 2 into the tube 6 is excluded (or almost excluded).

[0095]

When the chamber 2 is filled with the fluid to be dispensed and the volume of the chamber 2 increases (for example, due to the removal of pressure from the pressure surface 25):

- the dispensing valve 5 (more specifically, the membrane 12) becomes flat on the dispensing seat 105, and the valve 5 is in its closed state; the possibility of passing the fluid from the chamber 2 to the outlet 24 is excluded,

- the supply valve 4 is retracted and removed from the supply opening 124, and the valve 4 is in its open state; fluid may flow from tube 6 to chamber 2 so as to refill chamber 2.

[0096]

If desired, a sponge (not shown), cloth or impregnation means may be placed on the outer surface of the ring 28, which can be impregnated with the fluid exiting through the outlet 24. In this case, the outlet 24 does not open directly on the outside of the device 101 , but on a sponge, cloth or impregnation agent. This sponge, fabric, or impregnant conceals the outlet 24. The pressing surface 25, accessible from the outside of the user's hand device 101, is then located at least partially on the outer surface of the sponge, fabric, or impregnator, and possibly partially on the outer surface of the ring 28 Alternatively, the fabric or impregnator may be replaced with or connected to a strainer to filter the sediment.

[0097]

The inner part of the tube 6 and/or reservoir 13 contains at least one rib 15, configured to limit the compression of the tube 6 and/or reservoir 13, respectively, and limit the amplitude of the decrease in the volume of the tube 6 and/or reservoir 13, respectively.

[0098]

In one embodiment of the method of manufacturing the device 101, the dispensing valve 5 is installed in the dispensing cavity 8 by insertion through the dispensing opening 108, i. e. from the inside of the chamber 22 before welding or assembling the parts 21 and 22 of the chamber 2.

The dispensing channel connects the outlet 24 to the interior of the chamber 2.

The dispensing channel contains a cavity 8.

[0099]

The pressure surface 25 is located partly on the protruding portion 23 (around the outlet 24) and on the outer surface (opposite the inner side of the chamber 2) of the wall 22.

[0105]

The bottom wall 21 includes a recess configured to receive at least a portion of the mouthpiece 23 after the mouthpiece has moved towards the bottom wall 21.

This recess is also a guiding means 26.

The pressure surface 25 does not use the protrusion 23 to reduce the internal volume of the chamber 2 by deforming the deformable wall 22.

[0106]

In this embodiment, in FIG. 10 and 11, the device 101 includes a guiding means 26 configured to guide the displacement of the dispensing portion 23.

[0109]

The guide means 26 is configured to prevent any degree of freedom in the inclination of the mouthpiece 23 and to limit the displacement of the mouthpiece 23 along a single axis of movement aligned in the direction of the bottom wall 21.

The guide means 26 hides the deformable wall 22 from the user looking at the device 101 from outside the device 101.

[0110]

Next, a second embodiment of the device 102 according to the invention will be described with reference to FIG. 12, 13 and 14 only with respect to the embodiment of FIG. 1-3.

The device 102 includes a guiding means 26 configured to guide the displacement of the dispensing portion 23.

[0111]

The means 26 is configured to prevent any degree of freedom in the inclination of the mouthpiece 23 and limit the displacement of the mouthpiece 23 along one axis of movement aligned in the direction of the bottom wall 21.

The outlet 24 is configured to distribute the fluid in a direction substantially perpendicular to one axis of movement of the portion 23 and/or substantially parallel to the pressing surface 25. This configuration is referred to as lateral dispensing.

[0112]

The dispensing portion 23 (also referred to as the dispensing head 23) contains:

- cover 70 and

- box 71.

Insert 71 is inserted into cover 70.

Between the deformable wall 22 and at least a portion (more specifically, the lid 70) of the dispensing portion 23, the material is continuous. The wall 22 and at least part (more specifically, the lid 70) of the part 23 are joined in one piece of the same material without interruption of the material, such as PP.

[0113]

The cavity 8 is located inside the specified at least one section 70 (projection part 23) having material continuity with the wall 22.

Valve 5 is located inside said at least one section 70 (dispensing part 23) having material continuity with wall 22.

[0114]

The connection between cover 70 and insert 71 is sealed so as to seal chamber 38 to air or gas. This tightness is ensured, for example, by skirt 53 and connection 54.

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

[0115]

The device 102 contains an element 31 having two opposite ends, namely:

- end of 41 issuance and

- end of 51 innings.

The feed end 41 is located inside the dispensing portion 23.

[0116]

The protruding part 23 (more precisely the insert 71) contains the cavity 30 of the element.

The end 41 of the issue is located inside the cavity 30 of the element.

The dispensing end 41 is slidable within the cavity 30 of the element.

[0117]

At the feed end 51, a feed valve 4 is located.

The element cavity 30 includes at least one lug or protrusion 37 configured to block dispensing end 41 from sliding inside the element cavity 30 provided that the pressure on the pressure surface 25 is less than a minimum threshold value.

[0118]

The pressure surface 25 is designed to reduce the internal volume of the chamber 2 under the influence of pressure by moving towards the bottom wall of the protruding part 23 and the cavity 30 of the element so that:

- the end 41 of the issue slides into the cavity 30 of the element by immersion in the cavity 30 of the element; considering the tab or protrusion 37 (which is optional), and/or the friction between the inner walls of the element cavity 30 and the end 41, and/or the compression of the cavity 30 (for example, if the end 41 contains a piston, the cavity 30 then provides a spring effect , making it possible to eliminate the abutment 32 described below), the element 31 also moves towards the bottom wall, but with a smaller amplitude of movement than the amplitude of movement of the part 23 and the cavity 30; and

- the element 31 presses the supply valve 4 in its closed position against the supply opening 124 at least once (generally, the valve 4 begins to rise at the beginning of the movement, then it is pressed against the opening 124 until the pressure inside the chamber 2 drops to a certain level). This facilitates the refilling of device 102.

[0119]

The dispensing end 41 has a slit along its length.

The device 102 includes a stop 32 located inside the supply tube 6 .

The anvil is configured to press against the feed opening 124, or at least adjacent to the feed opening 124, in the absence of pressure on the pressing surface 25.

The feed end 51 is equipped with a stop 32.

In this embodiment, stop 32 is a stopper, i. e. it is configured to seal and close the feed opening 124 by pressing the anvil 32 against the feed opening 124 .

[0120]

At rest, i.e. without the impact of loads or external forces on the device 102, the anvil 32 is pressed against the opening 124 to feed. The pressure surface 25 is configured to reduce the internal volume of the chamber 2 under pressure by moving the protrusion 23 (and the element cavity 30 so that the protrusion end 41 slides into the element cavity by plunging into the element cavity) in such a way that the element 31 moves its stop 32 in the direction from the feed hole.

[0121]

In this embodiment, the cavity 8 has the shape of the letter T.

Dispensing valve 5 is located in the upper line of the letter T.

The dispensing valve 5 is located in the cover 70.

Seat 105 is located in cover 70.

Part 11 of the valve 5 is sandwiched between the inner walls of the cavity 8 (inside the cover 70).

To limit the inactive volume of the cavity 8, the dispensing head 23 contains a "forbidden" area 38 (or volume) into which the fluid to be dispensed cannot penetrate.

[0122]

This further facilitates the refilling of device 102.

Region 38, for example, is an air cavity or an area filled with a material, such as PP.

Thus, the cavity 30 is surrounded by a 360° circumference around the cavity 30 in its most part (more than 180°, preferably more than 270°) region 38, and additionally at least area 56 (lower band of the letter T) of the cavity 8. This channel 56 is also located in the cover 70, but may alternatively be located in the insert 71.

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

[0123]

Reservoir 13 is formed:

- a peripheral space 131 (usually in the form of a hollow cylinder formed by two concentric cylinders) in which the piston 132 (usually annular) is movable or sliding in accordance with the volume of fluid to be dispensed remaining in the reservoir 13, and

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

The opening 124 opens into the central space 133.

[0124]

An opening is provided between spaces 131 and 133 so as to allow fluid to pass between the two spaces 131 and 133. This opening is located on top of spaces 131 and 133, i. above the piston stop 132, i. e. this opening is configured to allow fluid to pass between spaces 131 and 133 regardless of the position of piston 132.

[0125]

Device 102 includes a refill connector 35 configured to allow device 102 to be refilled with fluid (more specifically, to fill the inside of tube 6 and/or reservoir 13) without the fluid passing through chamber 2, dispensing valve 5 or supply valve 4 .

[0126]

Connector 35 contains a refill valve 39 which:

- closed at rest and

- made with the possibility of opening when the means 35 is connected to the source of the fluid to be dispensed.

Valve 39 opens into central space 133.

The wall 22 has a wavy shape. This makes it easier to deform and/or provide a spring effect.

[0127]

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

This makes it possible to have a dispensing head 23 made in one piece with side dispensing.

It should be noted that the piston 132 slides into the device 102 without deforming the outer side of the device 102.

[0128]

Next, an embodiment of the device 102 of the second embodiment according to the invention will be described with reference to FIG. 15, 16 and 17 only with respect to its differences compared to FIG. 12-14.

[0129]

In this embodiment, stop 32 has a through hole 33.

The supply tube 6 has a through hole 34.

The anvil 32 is configured to block any flow of fluid through the supply port 124 until the through hole 33 of the anvil 32 faces the through hole 34 of the supply tube 6 .

[0130]

The through hole 33 of the stop 32 does not face the through hole 34 of the supply tube 6 in the absence of pressure on the pressing surface 25.

On its inner walls, the cavity 30 contains a screw thread, and at the end 41 has sections inserted into the screw thread.

[0131]

The pressing surface 25 is configured to reduce the internal volume of the chamber 2 under pressure by moving the protruding portion 23 and the element cavity 30 towards the bottom wall 21 so that the protruding end 41 slides by turning (due to the screw thread) in the element cavity 30 by plunging into element cavity 30.

[0132]

The pressing surface 25 is made with the possibility of reducing the internal volume 2 of the chamber under pressure by moving the protruding part 33 towards the bottom wall 21 in such a way that the element 31 rotates on its axis and the through hole 33 of the stop 32 addresses the through hole 34 of the supply tube 6 along at least once (for example, when the pressure inside the chamber 2 drops to a certain level).

[0133]

Next, a third embodiment of the device 103 according to the invention will be described with reference to FIG. 18-21 only with respect to its differences compared to the embodiment of FIG. 12-14.

In the device 103, the anvil 32 is not a stopper, but includes one or more fluid passage holes 40.

The device 103 includes a rod 36.

[0134]

Connector 35 for refilling is configured to:

push rod 36 into place upstream of dispense valve 5 (previous downstream of dispense valve 5 means along the fluid circulation path between connector 35 and valve 5) while connecting connector 35 for refilling with source 42 of the fluid to be dispensed so as to block the flow of fluid upstream of the dispensing valve 5, preferably so as to seal the supply port 124 and/or the dispensing port 108, and

- pull the rod 36 so that the rod 36 does not block the flow of fluid upstream of the dispensing valve 5, preferably so as to open the supply port 124 and/or the dispensing port 5, while disconnecting the source 42 from the refill connector 35.

[0135]

The rod 36 passes through the supply tube 6 and/or the reservoir 13 for the fluid.

More specifically, the refill connector 35 is configured to push the stem 36 (which may be a piston 36) toward the opening 124 so as to seal the opening 124 with the stem 36 and/or anvil 32 during attachment of the refill connector to the fluid source 42. environment to be released.

A plug 74 is located at one end of the rod 36.

[0136]

Thus, in this embodiment, at the time of attaching the refill connector to the source 42 of the fluid to be dispensed, the refill connector 35 is configured to press the stem 36 against the anvil 32 so that:

- keep the stop pressed against the feed hole 124 and

- seal the feed opening 124 with a rod 36, more specifically with a plug 74.

[0137]

Thus, it is possible to refill the reservoir 13 without the refilling of the fluid starting in the chamber 2 or outlet 24 under the influence of the refilling pressure.

Rod 36 is located inside the central space 133.

The refill connector 35 is configured to pull the stem 36 when the source 42 is disconnected from the refill connector 35 such that the stem 36 moves away from the opening 124 and does not seal the opening 124.

[0138]

The refill connector 35 is configured to pull the rod 36 when the source 42 is disconnected from the refill connector 35 so that the rod 36 does not touch the anvil 32 and does not block the displacement of the anvil 32.

[0139]

Chamber 2 initially contains a vacuum or reduced pressure relative to the contents of reservoir 13.

The device 103 may include a cap or lid (tight to gas and block any passage of gas, and not shown) such that abutment 32 is located between this cap or lid and opening 124.

[0140]

Push surface 25 is configured to push member 31 toward opening 124 by pressing push surface 25 such that stop 32 pushes rod 36 and moves rod 36 away from opening 124.

The anvil 32 is thus configured to pierce or open the cap or cap. This is required in particular when chamber 2 initially contains a vacuum so as to prime device 103.

[0141]

The bottom of wall 22 is pinched or pinched between guide 26 and bottom wall 21 so as to seal this pinched or pinched area of wall 22 and prevent fluid from passing between guide 26 and bottom wall 21.

It should be noted that this implementation includes only one valve 5 between the chamber 2 and the outlet 24, as in most of the illustrated embodiments of the present description.

[0142]

With reference to FIG. 22 in embodiments 102 and 103 of FIG. 12-21, part 11 of valve 5 is not only clamped by cover 70. In this embodiment, valve 5 (more specifically, part 11) is held between the inner walls of cavity 8 by being clamped between cover 70 and insert 71.

[0143]

Thus, in this embodiment, a large opening 205 or large cavity 62 (for part 11), a small opening 224 or small cavity 61, and the element 29 described with reference to FIG. 1-11.

A small hole 224 (or small cavity 61) is contained within a large hole 205 (or large cavity 62).

[0144]

The top of wall 22 is pinched or pinched between insert 71 and cap 70 so as to seal this pinched or pinched area of wall 22 and prevent fluid from passing between insert 71 and cap 70.

The wall 22 is an independent piece and has material continuity with the protruding part 23.

[0145]

For the method according to the invention in this embodiment, the valve 5 is located on an insert 71 which has a wedging or retaining device 72 (usually a pin, cavity, dovetail or small seal if the valve 5 is moved by sliding perpendicular to the axis insertion of the insert 71 into the lid 70) before the assembly formed by the insert 71 and the valve 5 is inserted and moved into the lid 70.

[0146]

The top of the device may be removable and housed in the reservoir 13, in particular the skirt 26 may be cut out (not to function as a housing and/or reservoir) and provided with means of connection to the reservoir 13.

[0147]

Next, a fourth embodiment of the device 104 according to the invention will be described with reference to FIG. 23 and 24 only with respect to its differences compared to the embodiment of FIG. 1-3.

[0148]

The internal volume of the chamber 2 is at least partially limited by the deformable wall 22 and the bottom wall 21.

Bottom wall 21 is integral with end portion 89, also referred to as notch 89.

The device 104 includes a reservoir 6, 13 bounded by walls 14 attached to the end 89, or more specifically, a flexible casing 14 welded to the end 89.

[0149]

The device 104 includes a supply opening 124 connecting the reservoir 13 to the interior of the chamber 2.

Chamber 2 is located inside tank 13.

The dispensing portion 23 has a dispensing opening 108 and is at least partially inserted into the end portion 89 on the side of its dispensing opening 108.

[0150]

The device 104 includes a pressure surface 25. The surface 25 is designed to reduce the internal volume of the chamber 2 under pressure (and by direct contact between the surface 25 and the wall 22, without passing through the protruding part 23) by deforming the deformable wall 22.

[0151]

The pressure surface 25 does not surround the outlet 24.

The outlet 24 is configured to distribute the fluid in a direction substantially parallel to the pressure surface 25.

The protruding portion 23 is not positioned on top of the concave shape of the deformable wall 22, i. e. on the top of the wall 22.

[0152]

The pressure surface 25 is configured to reduce the internal volume of the chamber 2 under pressure by deforming (and moving) the deformable wall 22 without moving the dispensing cavity 8 and the dispensing valve 5 towards the bottom wall 21.

[0153]

The cavity 8 extends along an axis perpendicular to the axis, which successively passes through the deformable wall 22, the chamber 2 and the bottom wall 21. The cavity 8 forms part of the protruding part 23 located or placed in the cutout 89.

The supply valve 4 is located in the chamber 2, and the dispensing valve 5 is located in the dispensing part 23.

[0154]

The dispensing valve 5 is connected to the supply valve 4 by means of a “passage channel 111” at the joint area, more specifically, the groove 111 in the valve is connected to the groove 88 or 18 in the cavity 8 (the implementation of the grooves on the flexible part or the rigid part can be reversed, the tightness is ensured by squeezing the flexible parts).

[0155]

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

[0156]

The dispensing valve 5 has a portion 11 held by clamping between the inner walls of the cavity 8 adjacent to the large opening 205 (or large cavity 62) and by clamping the protrusion 76 parallel to the longitudinal direction of the cavity 8, typically by clamping between the portions 23 and another part of the device 104 such as, for example, the part integral with the bottom wall 21, more precisely the notch 89. The protrusion 76 extends all around except for the fluid passage and seals between the parts 89 and 23; alternatively, this tightness can also be formed by clamping or welding between these two parts 89 and 23.

[0157]

Plug 77 is configured to pass between two positions:

- a closed position (shown in FIG. 23), in which part 771 (finger) of the plug 77 is inserted into the outlet 24 (more specifically, into the hole 224 (or cavity 61)) so as to seal the outlet 24, and this finger 771 is closed on the seat 156, and the distance between the closing of the dispensing valve 5, more precisely, the section of the seat 105 to the outlet 24, and the seat 156 is less than 6 mm, even 4 mm,

- an open position (shown in FIG. 24) in which this portion 771 of the plug 77 is not inserted into the outlet 24 (more specifically, into the hole 224 (or cavity 61)) so as to seal the outlet 24. The plug 77 is formed by molding with part 23.

[0158]

Chamber 2 is located inside tank 13.

The device 104 includes a supply valve 4 which, when open, allows fluid from the supply tube to pass towards the inside of chamber 2 through the supply opening 124, and when closed, prevents fluid from passing from the supply tube to the inside of chamber 2 through feed hole.

[0159]

The supply valve 4 is made in one piece with the dispensing valve 5.

The supply valve 4 and the discharging valve 5 are made in the form of one piece from the same material.

The supply valve 4 is located inside the chamber 2.

The dispensing valve 5 is located outside the chamber 2.

[0160]

The dispensing valve 5 is located in the device 104 in accordance with the assembly by insertion through the dispensing opening 108 or large opening 205 (or large cavity 62). The dispensing valve 5 is kept locked without any possible exit from the cavity 8 on the side of the dispensing opening 108 or the large opening 205 by blocking the end portion 89.

[0161]

The protruding part 23 contains a wall located outside the end part 89, and which:

- is visible from the outside of the device 104,

- runs along the dispensing valve 5 from the outlet 24,

- has a constant or substantially constant thickness.

[0162]

Next, a fourth embodiment of the device 104 according to the invention will be described with reference to FIG. 25-28 only with respect to its differences compared to the embodiment of FIG. 23-24.

[0163]

The pressure surface 25 includes a wall 22.

The pressing surface 25 forms part of the protruding part 23.

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

The cavity 8 extends along the axis parallel to the axis, which successively passes through the deformable wall 22, the chamber 2 and the bottom wall 21.

[0164]

The dispensing valve 5 comprises a portion 11 held (preferably by clamping) between the portion 23 (which forms the distribution wall) and another portion of the apparatus 104, such as a portion integral with the bottom wall 21. The reservoir 13 and its wall 14 are partially enclosed by a shell 222 comprising a portion 23, a wall 22 and an outlet 24, and partly a lower wall 21. The outlet 108 is a channel formed by part of the wall of the lower portion 21 and the sheath 222 (assembly).

Shell 222 and bottom wall 21 extend in the same direction.

[0165]

The rib 15, configured to limit the compression of the reservoir 13 and limit the amplitude of the decrease in the volume of the reservoir 13, is formed by the part containing the cavity 8, the part 23.

The flexible wall 14 is made of an elastomer or plastomer, such as a thermoplastic polyolefin (TPO).

Wall 14 is attached to part 23.

[0166]

Typically, edge 78 of sheath 222 wraps around wall 14, preferably wraps around the entire periphery of wall 14 so as to integrate the wall and connect it to part 23, typically by ultrasonic welding or ultrasonic flexing. A container having a relatively thin wall in the areas in contact with the fluid, product or liquid to be dispensed can be welded directly by ultrasonication.

[0167]

To fill the rest of the small opening 224 of the cavity 8 (or small cavity 61) towards the outlet 24, the dispensing valve 5 has an end 122 for flush connection with the dispensing surface 28 near the outlet 24. If desired, the end 122 may contact a second seat 155 closer to opening 24, valve 5 can provide a spring effect through cavity 121, cavity 121 being able to trap air bubbles. Preferably, the liquid outlet is preferably on the same surface, with the end 122 having the shape of a prism. The means for closing the dispensing valve 5 and more particularly the seat portion 105 to the outlet 24 is less than 6 mm, even less than 4 mm, from the outlet 24.

The cavity 8 is located inside the tank 13 and/or tube 6.

[0168]

Next, an embodiment of the first embodiment of the device 101 according to the invention will be described with reference to FIG. 29-32 only with respect to its differences compared to the embodiment of FIG. 6.

[0169]

According to an independent aspect of the previously described aspects of the invention, the internal volume of the chamber 2 is at least partially limited:

- the first part 81 containing the bottom wall 21 and the opening 124 for supply, and optionally the valve 4; if present, the valve 4 is installed on the supply port 124; wall 21 is designed so that only two outlets provide access to the inside of the tank 13: hole 124 and hole 79 for filling,

- the second part 82 containing the wall 22, and preferably the periphery 80, located around the wall 22.

[0170]

The internal volume of the reservoir 6, 13 is at least partially limited:

- the walls 14 of the tank and

- bottom wall 21.

[0171]

One of the walls 14 of the tank and the bottom wall 21 are connected (for example, by means of a flexible tongue) to the deformable wall 22 into one piece of the same material, i.e.:

- the walls 14 of the tank and the deformable wall 22 are assembled in one piece from the same material (in the case of FIG. 29 and FIG. 30), or

- the bottom wall 21 and the deformable wall 22 are assembled into one piece of the same material (in the case of FIG. 32).

[0172]

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

[0173]

It should be noted that the cartridge 800 has an edge 211 of the bottom wall 21 for engagement with the ribs 85 of the body 84, and/or the edge 211 is equipped with legs 85 for engagement with the bottom of the body 84. The cartridge 800 is held in the body 84 by the bottom wall 21.

The cartridge is inserted through the top of the housing after the movable dispensing wall 83 is removed.

[0174]

The invention relates to a method for manufacturing a device according to the invention, in which the reservoir 13 is filled with the fluid to be dispensed (preferably a liquid, cream, gel, paste or mixture thereof) by filling means.

[0175]

The chamber 2 may be in communication with the outside of the device so as to allow the gas contained in the chamber 2 to be easily ejected outwards until the product rises to reach a region downstream of the supply opening 124, 124b in two ways:

- either during filling with open deformable wall 22 (filling with or without pressure),

- either the wall 22 is closed (other option) by pressurizing the reservoir and/or filling under pressure due to the means, so that the dispensing valve is in the open or almost open position, in order to allow easy venting of air with a slight increase in gas pressure in chamber 2 Thus, means are provided for reducing the closing force of the dispensing valve, such as in the case of FIG. 41 or 42, just an outside tool that will push rod 58 towards the inside of chamber 2.

[0176]

Means not shown are provided for pressing the reservoir and/or opening and/or pressing the dispensing valve 5.

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

- the fluid filling the tank 13 penetrated through the hole 79, but could not exit the tank 13 through the hole 79 (for example, due to the absence of an interwall space between the fluid filling means introduced into the hole 79 and the circumference of this hole 79)

- the gas originally in the tank 13 could not exit the tank through the hole 79 (for example, due to the absence of an interwall space between the fluid filling means introduced into the hole 79 and the periphery of this hole; hole 79)

- the fluid filling the tank 13 and the gas originally inside the tank 13 could only leave the tank 13 through the supply opening 124 or 124b

- and preferably the chamber 2 is not yet formed so that the valve 5 or any other part does not block the withdrawal of fluid through the valve 4

- if necessary, if the chamber 2 is closed, the tool can be used to open the dispensing valve 5 in order to assist in pushing the air out of the device.

[0177]

This filling is carried out until the fluid to be dispensed exits the valve 4 and/or the supply port 124 relative to the reservoir 13, or reaches the interface between the valve 4 and the supply seat.

[0178]

In the embodiment in which the chamber 22 is closed, the filling hole 79 is not covered by the weld of the deformable chamber 22, but may be closed by the weld of the tongue 99 formed by molding with the deformable chamber 22 after filling. Advantageously, the filling opening 79 may be connected to a filling channel protruding from the bottom wall 21. In another embodiment, the bottom wall 21 has a skirt forming the side of the tank 6, on this skirt there is an element 79 for filling the opening, which can be closed by a tongue 99 wall 22, and which forms an angle of approximately 90° with the bottom wall 21.

[0179]

Furthermore, in this embodiment of the method according to the invention, the bottom wall 21 and the deformable wall 22 are assembled to form a chamber 2, and the opening 79 is sealed. Closing the hole 79 and assembly can be done at the same time. For example, it is possible to attach (for example, by ultrasonic welding) the periphery 80 to the wall 21 so that the fixed perimeter 80 covers the opening 79.

[0180]

Thus, thanks to this embodiment of the method according to the invention, the passage of the fluid to be dispensed can be easily initiated by the valve 4.

Preferably, the second part 82 also contains part 23 and/or cavity 8 and/or valve 5.

These two assembled parts 81, 82 are then spanned between the movable dispensing wall 83 containing the surface 25 and the housing 84.

[0181]

The movable dispensing wall 83 comes into contact with the wall 22 and/or the portion 23.

The legs or ribs 85 integral with the first section 81 and/or the body 84 are configured to maintain the position of the fixed wall 21 relative to the body 84 even if the volume of the tank 13 is reduced as a result of the removal of fluid from the tank 13.

In this version of the device 101, the device 101 includes a ring 28.

[0182]

The dispensing ring 28 is applied to the wall 22 and is preferably engaged or clamped on the dispensing portion 23 by a connecting pin 231 attached to the wall 22 and/or portion 23, as in the case of FIG. 4. (Less preferred, the opposite is possible: the connecting pin 231 may be located on the dispensing ring 28, and this pin extends into the dispensing portion 23). With reference to FIG. 31, it should be noted that the width d of the finger 231 is less than the width e of the part 23, preferably at least 1.5 times less than d < 1.5

[0183]

The pressure surface 25 is located on this ring 28.

The internal volume of the chamber 2 is limited at least partially by a deformable wall 22 and a bottom wall 21.

The device 101 includes a reservoir 13 bounded by the walls 14 of the reservoir and the bottom wall 21.

The bottom wall 21 is designed so that prior to the assembly of wall 22 and wall 21, only two outlets provide access to the inside of the tank 13: a supply opening 124 and a filling opening 79.

[0184]

At least one of the walls 14 of the tank and the bottom wall 21 are connected to the deformable wall 22 as one piece.

[0185]

Next, a third embodiment of the device 103 according to the invention will be described with reference to FIG. 33-35 only with respect to its differences compared to the embodiment of FIG. 22.

The outlet 24 is configured to distribute fluid in a direction substantially perpendicular to one axis of movement of the portion 23 and/or substantially parallel to the pressure surface 25.

[0186]

Continuity is provided between the deformable wall 22 and at least a portion (more specifically, the insert 71) of the protruding portion 23. The wall 22 and at least a portion (more specifically the insert 71) of the portion 23 are bonded into a single piece of a variety of materials, such as overmolding or double injection molding.

This version of the device 103 does not contain the element 31 or stop 32.

[0187]

In its closed position, the supply valve 4 closes the opening 124.

Valve 4 is located inside chamber 2.

The valve 4 is a tab attached to the wall 22 and made of the same material as the wall 22. The valve 4 is designed to be pressed against the hole 124 and the feed seat, when the wall is not yet assembled with the bottom wall (FIG. 34), the tab valve 4 extends substantially perpendicular to the longitudinal direction of valve 4 in its closed position and is pressed against the supply seat when assembled. Thus, the flap 4 has a tongue embedded in the deformable wall 22.

The stem 36 is integral with one end of the valve 39, which is a simple seal.

[0188]

The refill connector 35 is designed so that:

- push the rod 36 so as to move the seal 39 away from the connector 35 to open the fluid channel from the source 42 to the inside of the reservoir 13 (more specifically, towards the interior 133) when connecting the refill connector 35 to source 42 of the fluid to be dispensed, and

- spring 86 or other pushing means pushing stem 36 so as to return seal 39 towards connector 35 to close the opening of the fluid passage from source 42 to the inside of reservoir 13 (more specifically towards interior space 133) when disconnected source 42 from connector 35 for refilling.

[0189]

It should be noted that the deformable wall 22 is made without the possibility of movement in the cover 70. No part of the movable chamber functions in the cover 70. The cover 70 is superimposed on the flexible wall 22. The wall 22 is a bellows 230 with a top edge 228 connected to the cover 70 or with a protrusion 71 by material continuity, overmolding or double injection molding, and a lower edge 229 held under pressure between the bottom wall 21 and a skirt 261 at least partially delimiting the reservoir 13. The joints and/or connection with the edges 229 and 228 are sealed . The lid 70 may include a shoulder 227 to control the deformation forces of the wall 22 and/or to optimize the size of the chamber 2.

[0190]

As shown in FIG. 34, the valve 5 is located in the sliding cavity 52 of the cover 70 (and/or insert 71 in variants of the cavity 52), and then it is moved transversely towards the outlet so that the end 122 is flush with the outlet 24. This movement can be performed an assembly tool and/or an insert 71 (and/or a lid 70 in identical cavity variants 52) equipped with a means such as a protrusion 711. The protrusion 711 may also be located in the lid 70.

[0191]

The deformable wall 22 does not contain any moving parts inside the protruding part 23.

The dispensing portion 23 comprises a lid 70 and an insert 71, the insert 71 being inserted into the lid 70.

The dispensing valve 5 is held in the cavity 8 by clamping between the cover 70 and the insert 71.

[0192]

The dispensing valve 5 can be placed in the cavity formed by the assembly of the insert 71 and the cover 70, it can be placed in the channel formed in the insert 71, the valve 5 can be moved to the outlet 24 by sliding in this sliding channel 52. The dispensing valve is held in the axis of the sliding cavity 52 by a stop 75 and a ledge 711.

[0193]

There is no space between the inner wall of the cover 70 and the outer wall of the insert 71.

Cover 70 and insert 71 are mounted in direct engagement.

The insert 71 includes a rib or protrusion 711 configured to insert the dispensing valve 5 into its cavity 8 during the insertion of the insert 71 into the cap 70.

The deformable wall 22 is attached to the spout 23 by molding one piece on top of the other or double injection molding them.

[0194]

As shown in FIG. 35, device 103 includes means 55, 58, 67 to allow the device to be in two positions:

- position for the issuance of fluid

- position blocking the issuance of fluid.

[0195]

More specifically, device 103 includes ring 55.

The lug or thickening 58 is made in one piece with the protruding part 23 (more precisely, the cover 70) or the ring 55, and the channel 67 is made in one piece with the ring 55 or the protruding part 23.

By turning the ring 55 so that the lug 58 faces the channel 67, the dispensing portion 23 can be displaced and hence the fluid can be dispensed.

[0196]

In all other positions of the ring 55, blocking of the dispensing part 23 is ensured and, consequently, the issuance of the fluid.

The cavity 8 extends in a longitudinal direction perpendicular or substantially perpendicular to the longitudinal direction of the device 103.

The cavity 8 is sealed relative to the outer side of the device, with the exception of its outlet 24.

[0197]

[0217]

Valve 4 is a simple flat flexible tongue. In particular, the valve 4 does not include a foot or protrusion protruding from the flat shape of the tongue and recessed into the bottom wall 21. This improves the flexibility of the valve 4 and facilitates refilling. Additionally, this allows for a larger channel with two holes.

The valve 4 is preferably pressed against the bottom wall 21.

[0218]

The valve 4 is attached laterally by clips and/or by its middle section. The valve 4 is pressed against two supply holes 124 surrounding the middle portion of the valve 4 and bent so that this middle portion is in the middle of the cavity formed by the valve 4.

The valve 5 is located in the cavity 8 formed by one piece.

[0219]

The valve 5 is located between the end 300 of the chamber 2 and the through hole 301 through the part 23 and connects the chamber 2 to the cavity 8. This facilitates demoulding and manufacturing of the part 23. Therefore, between the parts 300 and 301, slightly moved away from the plane of FIG. 44, fluid communication is provided.

The tank 13 and its wall 14 are mainly closed by the part forming the bottom wall 21.

[0220]

The cavity 8 and part 23 are placed in the bottom wall 21.

The dispensing valve 5 is held in the dispensing portion 23 (or, in an embodiment not shown, between the dispensing portion 23 and the bottom wall 21).

The cavity 8 and the protruding part 23 are inserted into the bottom wall 21.

[0221]

At least one of the points of the dispensing valve 5 is located at a distance of less than 6 mm from the outlet 24.

The protruding portion 23 and the deformable wall 22 form one piece without material interruption.

The cavity 8 contains a small hole and a large hole, and the channel between the large hole 205 and the small hole 224 is formed by the element 29 of the cavity 8 for filling.

[0222]

Holes are drilled in the wall 21 and the part 23 to allow the reservoir 13 to be filled from the outside of the device 104 through these holes. These holes are sealed with two plugs 351 or 352, or one double plug 350. According to the embodiment shown in FIG. 44, double plug 350 (i.e., one solid piece) has a hole drilled to allow fluid to pass between part 23 and wall 21 in chamber 2 and/or a channel connecting chamber 2 to cavity 8.

[0223]

This device 104 may be filled according to a filling process in which chamber 2 is at atmospheric or reduced pressure.

The cover 351 or the top of the plug 350 closes the interaction surface between the outside of the device according to the invention and the chamber 2.

The lid 352 or the bottom of the plug 350 closes the interaction surface between chamber 2 and reservoir 13.

[0224]

As in the case of FIG. 32 (where pressing the valve 4 to open it in all cases also causes the opening of the chamber 2), the filling process in this embodiment includes the step of filling the reservoir 13 with the fluid to be dispensed, the chamber 2 communicating with the outside of the device according to the invention , without passing through a valve 5 normally open to atmospheric pressure and/or to the outside of the device according to the invention and/or connected to a source of reduced pressure.

[0225]

Alternatively, one plug 351 may be provided (ie, in an embodiment without plug 352) just to fill chamber 2 in an independent step.

[0226]

Finally, according to the invention, the step of filling at least part of the chamber 2 when it is open (i.e. under conditions of atmospheric or reduced pressure, and in communication with the outside of the device according to the invention without passing through the valve 5) can be provided. , either at the same stage of filling the reservoir 13, or before or after the stage of filling the reservoir 13 (in the case of the plug 351 of the chamber).

[0227]

Next, a fourth embodiment of the device 104 according to the invention will be described with reference to FIG. 46 and 47 only with respect to the embodiment of FIG. 23.

Part 23 and wall 21 are one piece without material interruption.

End part 89 and part 23 are one piece without material interruption.

[0228]

The end portion 89 and the wall 21 are one piece without material interruption.

The cavity 8 has an oblique direction 302 of inclination forming an angle 303 (preferably at least 3°, preferably at least 6°, typically 9 ± 2°) relative to at least one plane 304 of the placement of the wall 22 on the part forming the bottom wall 21 to secure wall 22 to wall 21. This facilitates insertion of valve 5 into cavity 8.

[0229]

The accommodation area 305 between the wall 22 and the portion forming the bottom wall 21 is not perfectly flat, but contains:

- plane 304 and

- a gap 306 at the intersection between the longitudinal direction 302 of the cavity 8 and the area 305 of the placement.

[0230]

The placement plane 305 and wall 21 are preferably made of a material that is more rigid than wall 22. This allows ultrasonic or high frequency welding to be facilitated.

The wall 22 is connected to the wall 21 by a pleat region 307, the wall placement plane 22 is applied to the portion forming the bottom wall 21 as shown in FIG. 47 by means of a pleat 308 of the pleat area 307 by folding the wall 22 into the portion forming the lower wall 21.

[0231]

The flap 5 is integral with the ridge 328 so that the ridge 328 is positioned between the flap 5 and the wall 22. The ridge 328 extends substantially perpendicular to the longitudinal direction of the cavity 8. This ridge 328 helps prevent accidental overlapping of one of the plurality of flaps 5 on another in the cavity 8 during the automatic assembly of the valve 5 during the manufacture of this embodiment of the device according to the invention.

[0232]

Part integral with valve 5 and connecting valve 5 to comb 328:

- initially forms an angle, the apex of which points to the direction opposite to the bottom wall when the valve is on the bottom wall before it is inserted into the cavity 8, and

- is flat in the sectional plane (according to FIG. 46) by limiting the longitudinal direction of the cavity 8, after the introduction of the valve 5 into the cavity 8.

This makes it possible to better hold the valve 5 in the cavity 8.

[0233]

Next, the fifth embodiment of the device 335 according to the invention will be described with reference to FIG. 48-52 only with respect to its differences compared to the embodiment of FIG. 23.

In this embodiment, chamber 2 forms a pear shape.

FIG. 48 part of the wall 14 is not shown so that the wall 22 can be distinguished.

[0234]

The valve 5 is installed in the cavity 8 by insertion on the side of the dispensing opening 108.

Part 23 and part 89 are the same part, preferably without material interruption.

The valves 5 and 4 are made in one piece and formed from the same piece, usually forming the valve tube 4, 5 shown in FIG. 50.

[0235]

At the first end of this tube of valves there is a valve 5 containing two tabs, made with the possibility of approaching each other in the open position of the valve 5, these two tabs are made with the possibility of separation by elements (like a chamber or others), which are made with the possibility of applying a restoring force to these reeds, which moves the valve 5 from its open position to its closed position. For example, each tab of valve 5 is integral with chamber 309 and two chambers 309 are in contact with each other between the two tabs.

[0236]

At the second end of this tube of valves is a valve 4 containing two tongues, made with the possibility of approaching each other in the open position of the valve 4.

The device 335 is provided (preferably at the end portion 89) with a stopper 310 to seal the hole opening on the inside of the tank 13. This stopper 310 allows the tank 13 to be filled.

As shown in FIG. 51, part 23 forms a spout 311 in which cavity 8 is located.

On spout 311 is tongue 314, also referred to as stop 314. Element 314 is substantially perpendicular to spout 311.

[0237]

Part 23 and tank 13 are installed inside the housing 312, 313. The housing is formed by two parts 312 and 313, respectively.

Part 312 is made of material without material interruption.

Portion 312 includes wall 316 extending along the outer side of wall 14.

Part 312 contains head 315.

Part 313 includes wall 321 extending along the outside of wall 14.

[0238]

The spout 311 is installed by insertion into the head 315 from the inside of the body 312, 313 before the two parts 312 and 313 are assembled. held between the head 315 on one side and the wall 321 and/or part 89 on the other side.

[0239]

The applicator 317 is mounted (usually clamped) on the head 315.

Seal 318 is compressed between spout 311 and applicator 317 in the axial direction, i. e. parallel to the longitudinal direction of spout 311. Applicator 317 includes massaging element 319, preferably metal or plastic, brush 319, foam 319 and/or brush 319, etc.

[0240]

The applicator 317 is clamped onto the head 315 of the body 312, 313.

The seal 318 is a separate part of the head 315 or is molded over the head 315 and is integral with the head 315.

The chamber 2 is connected to the dispensing part 23 by being attached to the tube 329.

More specifically, the pear-shaped end of the chamber 2 is recessed (preferably an interference fit) on or in the tube 329.

[0241]

The tube 329 is part of the dispensing part 23.

The tube 329 forms one of the ends of the protruding part 23.

This tube 329 has an adjustable length in accordance with this implementation, in particular, as a function of the size of the reservoir 13. For example, the scale of FIG. 49, the page of which is to be printed on an A4 sheet, is approximately 2 times the actual size of the 335.

[0242]

The chamber 2 is blown, for example, from a polyolefin material.

Seal 318 may be attached to and/or molded over head 315 or applicator 317.

The applicator 317 is clamped against the head 315. The applicator 317 includes one or more buttons 331 configured to release the applicator 317 relative to the head 315.

[0243]

In a variant not shown, the chamber 2 is formed by the same part as the end part 89 and/or the protrusion part 23, without material interruption. For example, chamber 2 could be formed by:

- a rigid or flexible bottom wall 21 integral with the end part 89 and/or the protruding part 23 without material interruption, and

- flexible wall 22 (small thickness), made in one piece with the bottom wall 21 without interruption of the material, and connected to the bottom wall pleat 307, as in the case of the previous FIG. 47. However, unlike FIG. 47, the pleat 307 is preferably located opposite the end portion 89 relative to the chamber 2.

[0244]

In the not shown embodiment of FIG. 49, outlet 24 is expanded to have a cross-sectional area or diameter equal to the cross-sectional area or diameter of cavity 8. In this embodiment, valve 5 may be introduced into cavity 8 through outlet 24. Additionally, device 335 may be filled with fluid by filling through the outlet 24 by filling all or part of the tank 13 and all or part of the chamber 2 before the introduction of the valve 5 into the cavity 8. This improves the filling of the device 335. In this case, the valves 4 and 5 are shown in FIG. 50b, and the device does not include a groove/channel 18 in the cavity 8. In this case, the part forming the flaps 4, 5 has a protrusion 337 or clip 337 placed in the receiving opening(s) 124.

[0245]

The plug 351 seals the interaction surface between the outside of the device according to the invention and the chamber 2.

Plug 352 seals the interface between chamber 2 and reservoir 13.

Plug 351 is at least partially formed by valve 5.

Plug 352 is at least partially formed by valve 4.

[0246]

Seal 318 is designed to be easily removable and can preferably be placed in part 312, 315, in particular for cleaning. Preferably, the seal 318 is removable and can be supported with the applicator interlocked in the head 315 or in the applicator 317.

[0247]

In a variant not shown, part 23 may be made of two parts separating valves 4 and 5, these two parts are connected by a sealed connector, which may be in part 89. These two parts may be permanently connected to each other. Preferably, the spout containing the dispensing valve 5 is one piece. Filling can be performed before the dispensing valve is attached.

[0248]

This protruding portion 23 may be fitted into a housing or cover for protection. Thus, it can be attached after filling at the same time as the casing or cover is installed for protection. The connection can be made without the possibility of further removal at the end of the connection operation after filling/closing the protective cover-cover. This also applies in the case of a valve. The spout can be replaced by a head. The protruding part 23 seals/closes the chamber 2.

[0249]

Wall 22 is located in casing 14.

With reference to FIG. 49, it should be noted that the product (fluid) to be dispensed passes to one side and the other in the same inlet and outlet of the chamber 2 to enter and exit the chamber.

[0250]

Next, we will describe with reference to FIG. 53 is an embodiment of the cavity 8 that can replace the cavity 8 of each of FIGS. 1-40, 44-47 and 57-58, only with respect to its differences compared to the embodiment of FIG. 28.

[0251]

In this embodiment, the cavity 8 includes an angled vertex 320 in contact with the wall of the cavity 121 configured to form a lateral compression region of the cavity 121. This improves the tightness of the valve 5.

[0252]

Next, a sixth embodiment of the device 106 according to the invention will be described with reference to FIG. 54-56 only with respect to its differences compared to the embodiment of FIG. 33.

In this embodiment, the pressure surface 25 is configured so that the pressure (depicted in FIG. 55) on the surface 25 deforms the wall 22 by squeezing the wall 22.

[0253]

A rigid element 322 (usually a tube) connects the bottom wall 21 and the protruding part 23, and is configured to direct the movement of the part 23 relative to the bottom wall 21.

The element 322 is integral with the wall 21. The element 322 and the wall 21 are inside the same part without material interruption.

The element 322 penetrates the part 23 and is slidable in the part 23 (more precisely, in the insert 71).

[0254]

Spring or return means 323 (optional) is configured to return the valve 5 from its open position to its closed position. Return means 323 includes a deformable ring surrounding member 322 which is compressed between piece 23 (more specifically insert 71) and valve 5 when valve 5 is in its open position.

[0255]

The valve 5 includes a movable element, preferably a rigid or semi-rigid ring, surrounding the element 322. In the closed position of the valve 5 (FIG. 54), the valve 5 seals the channel connecting the chamber 2 with the outlet 24. In the open position of the valve 5 (FIG. 55) , the valve 5 is moved so as not to seal this channel connecting the chamber 2 with the outlet 24; more specifically, it is moved:

- sliding into part 23 (more specifically in insert 71) when approaching exit 24

- sliding around the element 322 when approaching the bottom wall 21.

[0256]

The movement of the valve 5 is provided by relative friction, on the one hand, between the valve 5 and part 23 (more precisely, the insert 71) and, on the other hand, between the valve 5 and the element 322. Preferably, the friction on the element 322 is more important to ensure easier movement of the valve 5 in insert 71 to open opening 712 in insert 71 (higher pressure also moves valve 5). The opening 712 is formed laterally with respect to the element 322. When the pressure surface 25 is pressed, the fluid of the chamber 2 circulates between the element 322 and the insert 71 and then passes into the opening 712 laterally from the center of the device or element 322, and follows the path, essentially parallel to axis 322 (outward from 322).

[0257]

The fixing ring 324 surrounding the wall 21 fixes the bottom wall 21 to the tank 13 by clamping.

The tube 325 connecting the inside of the tank 13 to the outside of the device 106 without passing through the chamber 2 allows pressure balancing between the inside of the tank 13 and the outside of the device 106 when the valve 5 is in the open position, and this tube 325 is opened (FIG. 55) when valve 5 is in its open position. This tube 325 is closed (FIG. 54) when the valve 5 is in the closed position, and then this tube 325 (more precisely, the opening 712) blocks the valve 5.

[0258]

The wall 22 is visible to the consumer from the outside of the device 106.

The device 106 works even if the head is pressed slightly, in which case the valve 5 can be opened.

[0259]

Device 106 includes a locking device that locks:

- the relative position of the cap 70 and the insert 71 such that the insert 71 closes the passage 330 connecting the valve 5 to the outlet 24 on the interface between the cap 70 and the insert 71 (upward position of the cap or head), and

- the relative position of the cap 70 and the insert 71, which is different in case the valve 5 is closed, so that the insert 71 does not close the channel 330 connecting the valve 5 with the outlet 24 on the interface between the cap 70 and the insert 71 (pressed down position of the head or lids).

[0260]

Valve 5 is configured to remain open (with a minimum opening of 1 mm ² for at least 0.5 seconds) without requiring a mandatory overpressure of more than 0.2 or 0.5 bar in chamber 2 relative to outlet 24.

The wall 22 and/or the insert 71 and/or the ring 324 may be formed in the same piece, for example by overmolding, and may therefore be integral. Ring 324 may be screwed or clamped.

The supply tube 334 is preferably located around the center, the channel 332 connects the tube 334 and the valve 4 in the bottom wall 21. This channel 332 is sealed laterally by the section of the chamber 2 and/or ring 324.

[0261]

Unlike FIG. 33, in which the guide 26 was outside the part 23 or insert 71, in the case of FIG. 54 the guide means 26 are inside the part 23 or insert 71 and are preferably formed by an element 322 sliding in the insert 71.

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

[0262]

In this regard, it should be noted that this embodiment of the device in accordance with the invention contains a rigid element 322 connecting the bottom wall 21 and the dispensing part 23 and configured to direct the movement of the dispensing 23 part relative to the bottom wall 21, and the dispensing valve 5 is slidable by friction around the rigid member 322 so that, in the open position of the dispensing valve 5, the dispensing valve releases a channel for the fluid to be dispensed along a side channel (more specifically, opening 712 of this side channel) located in the dispensing portion 23 and connecting the chamber 2 with outlet 24.

[0263]

Next, a sixth embodiment of the device 106 according to the invention will be described with reference to FIG. 57-58 only with respect to its differences compared to the embodiment of FIG. 54-56.

[0264]

The cavity is only in insert 71.

In this embodiment, the insert 71 contains a cavity 8 containing an outlet:

- opening on the outer side of the insert 71 without passing through chamber 2

- opening into the environment before assembling the insert 71 and cover 70

- closed by lid 70 after assembly of insert 71 from lid 70.

This allows the valve 5 to be easily introduced into the cavity 8 through this outlet.

[0265]

The internal volume of chamber 2 is limited:

- on top of the wall 326 of the part 23 (more specifically, the insert 71), which also defines the cavity 8

- from below the bottom wall 21

- from the sides with a deformable flexible wall 22.

Wall 22 and wall 326 are portions of part 23, more specifically insert 71. Wall 22 is integral with wall 326 and is typically molded over wall 326.

This wall 22 is foldable during pressing on the surface 25, as shown in FIG. 58.

[0266]

The valve 4 contains a flexible wall located on the bottom wall 21.

The wall 22 and/or the lid 70 and/or the insert 71 and/or the ring 324 may be formed in the same piece, for example by overmolding, and therefore may be integral. In the case where wall 22, cover 70, insert 71 and ring 324 are made in one piece, outlet 24 is enlarged compared to FIG. 57 to enable the insertion of the valve 5 into the cavity 8 through the outlet 24.

[0267]

The chamber 2 has the shape of a truncated cone, the apex angle 333 of which is less than 20°, preferably less than 10°, even 5°.

The protruding part 23 is located on top of the chamber 2, which has the shape of a truncated cone.

[0268]

Next, a seventh embodiment of the device 700 according to the invention will be described with reference to FIG. 59-64 only with respect to its differences compared to the embodiment of FIG. 40.

In this embodiment, the cartridge or module 800 no longer contains valve 5.

[0269]

The valve 5 is located in the cavity 8 located in the head formed by the dispensing part 23.

More specifically, the cavity 8 is in the tube 701 (as shown in FIG. 59) or module 701 (as shown in FIG. 62).

Tube 701 or valve module 701 is built into part 23.

The dispensing part 23 has the shape of a spout, and the cavity 8 is located in a part 701 that is removable relative to the dispensing part 23

[0270]

Part 23 includes connecting means 702, which may include penetrating means 708 configured to penetrate wall 22 at the same time as means 702 are introduced into device 700.

[0271]

Tools 702 contain:

- either the end of the tube 701 opposite the end of the tube 701 containing the valve 5: in this case, these means 702 (708) are made with the possibility of contact with the wall 22 by punching it, when the part 23 is already placed in the device 700 and the tube 701 is inserted into the part 23 and/or when the part 23 already containing its tube 701 is inserted into the device 700,

- or a section made in one piece with part 23: in this case, these means 702 (708) are made with the possibility of connecting with the wall 22 and punching it when part 23 is inserted into the device 700.

[0272]

Preferably, the central region of the wall 22 contains connecting means 703, 704, 710, configured to connect with the means 702:

- in this case, shown in FIG. 59-64, the connecting means 702 of the part 23 comprise means 708 for penetrating the connecting means 703, 704, 710 of the wall 22. These means 703, 704, 710 are configured to be pierced by the means 702 and may comprise a sheath 710 of a different material or with material continuity relative to the rest of the wall 22. These means 703, 704, 710 form a connection with the interior of the chamber 2.

- In a reverse version not shown, the means 703, 704, 710 for connecting the wall 22 comprise means 708 for punching the connecting means 702 of the part 23.

[0273]

The seal 703 is configured to seal the joint (sealed connector) between the outer periphery of the means 702 and the wall 22. This seal 703 is either located on the outer periphery of the means 708 (FIG. 64) or integral with the wall 22. (FIG. 61) .

[0274]

Wall 22 forms a connector 703, 704, 710 located on wall 22 and located:

- in the case of FIG. 59-64 within the chamber 2 and configured to form a receiving cavity 704, means 702. This cavity or recess 704 is located between the shell 710 or punched area of the wall 22 and the seal 703.

- in the opposite not shown embodiment, outside the chamber 2 and is made with the possibility of forming a pin 704 connection with the means 702.

[0275]

In the case of the variant of FIG. 60 and 61, part 23 is made in the form of two parts, made with the possibility of rotation relative to each other to allow the introduction of the tube 701 from above, when this tube is straight or substantially straight, before folding this tube 701, to then be able to cover the two parts of part 23 .

[0276]

FIG. 62-64 the two parts of the part 23 are rotatable in the vertical direction, and in FIG. 59-61 they are made with the possibility of rotation in the horizontal direction. The tube or valve module 701 is removable from part 23 and is held in a fixed position by the two parts of part 23.

[0277]

Alternatively, the means 702 are not designed to penetrate the wall 22, but are capable of being inserted directly into or connected to the opening formed in the wall 22. This opening may be formed, for example, by a removed cover.

[0278]

The device 700 includes a housing 705 (in housing 84) configured to push the reservoir so as to lift fluid from the reservoir to chamber 2 during insertion of cartridge 800 into housing 84.

This device 700 is a bottle, head forming part 23 located on top.

[0279]

The filling method of this device 700 comprises raising fluid from reservoir 13 to chamber 2 while chamber 2 is in fluid communication with the outside of device 700, either by first penetrating wall 22 (for example, by manually removing a cap or the like) or by penetration of wall 22 by means 702, but before means 702 reaches seal 703. This lift is due to the pressing of shroud 705 on cartridge 800, the shroud may be part of the housing. This lift delivers the product to at least the inlet valve seat 4.

[0280]

The bottom wall 21 includes a recess configured to receive at least a portion of the protrusion 23, more specifically the connector 702, after the protrusion has been moved towards the bottom wall 21. This recess also constitutes the guiding means 26.

Connector 702 is preferably sterile.

[0281]

Therefore, a cartridge 800 or non-removable module (see FIG. 49) is provided for device 700, the cartridge comprising:

- bottom wall 21

- valve 4 supply

- a chamber 2 equipped with a connector 704, 703 (made with the possibility of connection with the dispensing valve 5) containing elements 704 and 703 and at least one part made with the possibility of punching or opening, and this chamber 2 contains a deformable wall 22

preferably a flexible reservoir 13 formed by a film 14 and/or a skirt formed by a bottom wall 21 or a deformable wall 24. This reservoir 13 is completely or partially filled (preferably at least at the inlet valve seat, preferably at least 10% of its internal volume or even at least 30% (depending on the viscosity of the fluid) of its internal volume) by the product (fluid) to be dispensed.

- tank 13 can be ultrasonically welded to wall 21 and/or wall 22.

[0282]

Naturally, the invention is not limited to the examples described, and many adjustments can be made to these examples without departing from the scope of the invention.

It should be noted that in all embodiments, wall 22 functions as a spring.

It should be noted that in all embodiments, the possibility of filling even with the head up is provided.

[0283]

For example, in a variant of the device 102 or 103, the valve 4 can be replaced by a valve 4 in the form of a "tongue", as in FIG. 1-11. In this case, the channel 30 (and element 31) disappears and the air cavity 38 occupies almost the entire part 23.

[0284]

In the embodiment of device 103 of FIG. 18-21, stem 36 is configured to close not valve 4 but valve 5 or dispensing opening 108. To do this, stem 36 extends through bottom wall 21. Valve 4 is located in a position offset laterally from the views of FIG. 18-21.

Wall 22 may be in the shape of a dome 22 and wall 21 may also be in the shape of a dome (so as to form a bubble).
