[0239] It should be understood that the embodiments to be described below are by no means limiting. Variants of the invention may be specifically considered which only include the selection of the following description or illustration of features independent of the description or illustration of other features (even if the selection is independent in the sentence including these other features), if the feature selection is sufficient to confer a technical advantage or to distinguish the invention relative to the prior art; if the part alone is sufficient to confer a technical advantage or to distinguish the invention relative to the prior art, the selection includes preferably at least one functional feature without structural details, and / or only with part of the structural details.

[0240] In particular, all of these variants and all of these embodiments described can be combined with one another if there are no reasons which prevent such a combination from a technical point of view.

[0241] In these figures, parts common to the several figures retain the same reference numerals.

[0242] First, we will refer to Figures 1 to 6 , describing a first embodiment of a device for dispensing a fluid according to the present invention.

[0243] exist Figures 1 to 3 In the invention, the device 100 for dispensing a fluid comprises:

[0244] a bag 2 having an internal volume containing said fluid, said internal volume being at least partially delimited by a deformable wall 4,

[0245] - a reservoir 6 having an inner envelope containing said fluid,

[0246] a feed orifice 8 for connecting the internal volume of the reservoir 6 with the internal volume of the bag 2,

[0247] a dispensing head 10 fixed to said deformable wall 4 of said bag 2 so that said dispensing head 10 is carried by said deformable wall 4 according to different possible positions relative to said reservoir 6, said different positions comprising at least:

[0248] * a stable position 12 when no external force 18 is applied to the dispensing head 10, and

[0249] an inclined position 14 , at an angle of inclination 16 relative to the stable position 12 , which, when an external force 18 is applied to the dispensing head 10 , deforms the deformable wall 4 and thus reduces the internal volume of the bag 2 relative to the stable position 12 ,

[0250] a dispensing channel 20 , located inside the dispensing head 10 , arranged to direct the fluid from the internal volume of the bag 2 towards an outlet 24 located at one end of the dispensing head 10 ,

[0251] A dispensing orifice 22 for connecting the internal volume of the bag 2 with the dispensing channel 20 .

[0252] In the present description, all positions of the dispensing head are defined in a reference plane in which the feed orifice and / or the reservoir are fixed.

[0253] In this specification, the term "flexible" will be understood to mean that any part can be deformed under the action of at least 1 kg, for example, has a bending modulus of less than 600 megapascals (MPa) and / or has a sufficiently small thickness.

[0254] In the present description, the term "rigid" is understood to mean any part that cannot be deformed under an action of at most 1 kg, for example, has a bending modulus greater than 600 MPa and / or has a sufficiently large thickness.

[0255] The dispensing head 10 comprises a contact surface 26 arranged to receive an external force 18 from outside the device, said external force being perpendicular to the longitudinal direction of the dispensing head 10 in the stable position 12 .

[0256] The dispensing head 10 of the device 100 extends longitudinally over a length of at least 10 mm (preferably at least 20 mm, even at least 30 mm or even at least 40 mm) according to:

[0257] - Longitudinal direction (through Figure 1 , for connecting the dispensing orifice 22 to one end of the dispensing head 10 (preferably carrying the surface 26 and / or the outlet 24), and / or

[0258] - Direction (via Figure 1 ), for connecting the dispensing orifice 22 with the outlet 24, and / or connecting the dispensing orifice with the surface 26 (preferably carrying the outlet 24).

[0259] In particular, a long lever arm can reduce these forces for the dispensing, for example to less than 1 kg, or even less than 0.5 kg if the device is an applicator for facial treatments (compared to a common pump requiring a pressure of 2 kg). The dispensing head 10 and the reservoir 6 extend longitudinally in the longitudinal direction when the dispensing head is in its stable position.

[0260] The dispensing head has a length (along the longitudinal direction) greater than a width (perpendicular to the longitudinal direction).

[0261] The contact surface 26 (accessible from the outside of the device 100 by a user's hand or even fingers or face) has a minimum surface area of ​​10 square millimeters when the contact surface 26 is arranged to contact the face, and preferably has a surface area of ​​at least 20 square millimeters (preferably at least 30 square millimeters, preferably at least 60 square millimeters, more preferably at least 100 square millimeters).

[0262] The axis A extends in the direction X.

[0263] In the stable position of the device according to the invention, the contact surface 26 (over a width of less than 15 mm, in a plane perpendicular to the direction X, and over an area of ​​at least 30 square millimeters, preferably over an area of ​​at least 60 square millimeters, more preferably over an area of ​​at least 100 square millimeters) forms an angle of -45° to 45° (more precisely -30° to 30°, most precisely -20° to 20°) with the direction X, along which the dispensing channel 20 extends at the outlet of the bag 2.

[0264] The distance between the outlet 24 and the axis A is less than 10 mm.

[0265] The distance between the surface 26 and the axis A is less than 10 mm.

[0266] The outlet 24 is located on the surface 26 .

[0267] The dispensing head 1 is arranged to be tilted on the side opposite to the contact surface 26. The dispensing head may have an application and / or massage element on its end, which may be made of metal, located on the face opposite to the contact surface 26. The device is arranged so that the force on the surface causes the dispensing head to tilt little or not at all, thereby limiting or preventing the outflow of the product.

[0268] The bag 2 is mainly composed of three parts. A first part comprises the deformable wall 4 , a second part comprises the rigid wall 54 , and a third part 84 (part of the bag 2 ) is arranged to be fixed on the reservoir 6 .

[0269] The rigid wall 54 of the bag 2 is located below the deformable wall 4. The deformable wall 4, more precisely its lower part, is fixed or integrated with the rigid wall 54 of the bag 2, at the level of the connection point 58.

[0270] The deformable wall 4 of the bag 2 is composed of a portion 4 1 and part 4 2 composition.

[0271] These parts 4 1 and 4 2 The portion 4 of the deformable wall 4 1 Arranged to bend under the compression of said force 18, said portion 4 of said deformable wall 4 2 The extension under the traction force is very small, but the deformation wall moves less than the part 4 1 , thereby improving the dispensing head 10 of the device 100 at the level of the contact surface 26 of the dispensing head 10 when the external force 18 is applied to the dispensing head 10 1 To improve the inclination of part 4 1 The tilting of the portion 4 of the dispensing head 10 in the stable position 12 1 The length of the curve in the cross section exceeds (eg, is longer than) portion 4 2 length (this forms the hinge).

[0272] Thus, the deformable wall 4 comprises asymmetric portions about the axis A, so that the bag 2 is arranged to improve the tilting of the dispenser head 10, in a favourable tilting direction, that is to say opposite the contact surface 26 and / or opposite the surface of the outlet 24. These portions 4 are thus 1 and 4 2 asymmetry, thereby improving the dispensing head 10 in the portion 4 1 on one side.

[0273] Thus, the deformable wall 4 of the bag 2 comprises:

[0274] a certain flexibility, allowing tilting of the dispensing head 10, that is, from its stable position 12 to an inclined position 14, and

[0275] - an elastic restoring force arranged to return the dispenser head 10 , tilted according to its tilted position 14 , to its stable position 12 .

[0276] For example, the deformable wall 4 is a thin wall, and for example the rigid wall 54 is a thicker wall than the wall 4 .

[0277] Preferably, the deformable wall 4 can be combined with the wall 54 by "co-casting", that is, by injection molding or double injection of materials, which have different elasticities, preferably PP is used for the rigid wall 54 of the bag 2 and TPO is used for the deformable wall 4 of the bag 2.

[0278] The deformable wall 4 and the rigid wall 54 are formed in such a way that the ... 1 and 4 2 It is also possible to inject all at once, for example, when the rigid wall 54 and the deformable wall 4 of the bag are made of polypropylene.

[0279] The deformable wall 4 is preferably made of PP, using polymer or plastic additives (e.g., Vistamaxx TM 6202) in order to reduce its hardness so that the hardness of the wall 4 is less than 80 Shore A. Thus, too great a fineness and weakness of the wall 4 is avoided.

[0280] The rigid wall 54 is arranged to be fixed to the third portion 84 of the bag 2 .

[0281] At the level of the weld or connection point 58, a stop 66 is provided for connecting the third portion 84 of the bag 2 to the rigid wall 54 of the bag 2. The stop 66 is perpendicular to the axis A when the device 100 is in the stable position 12.

[0282] The deformable wall 4 of the bag 2 fixes the dispensing head 10 .

[0283] The bag 2 is fixed to the dispensing head 10 . The bag 2 is inserted into the dispensing channel 20 of the dispensing head 10 in particular by means of a ring 88 .

[0284] The dispensing head 10 comprises the ring 88, located at the junction between the internal volume of the bag 2 and the dispensing channel 20, in which the dispensing orifice 22 is located. In particular, the deformable wall 4 of the bag 2 is pressed against the dispensing channel 20 by the ring 88, at the level of the junction between the internal volume of the bag 2 and the dispensing channel 20. The ring 88 is clamped and fixed on the dispensing head 10. The ring 88 is arranged to be fixed on the dispensing channel 20 by force.

[0285] The dispensing head 10 is traversed over its entire length by the dispensing channel 20 .

[0286] The dispensing channel 20 starts at the level of the dispensing orifice 22 and extends to the outlet 24 accommodating the dispensing head 10 .

[0287] In addition, the dispensing head 10 includes a dispensing valve 28, which is located in the dispensing channel 20 and allows fluid to flow out of the outlet 24 from the dispensing channel 20 when the dispensing valve is in an open state, and does not allow fluid to flow out when the dispensing valve is in a closed state.

[0288] The dispensing valve 28 is generally made of the thermoplastic polyolefin or TPO (polyolefin composition: polyethylene and polypropylene) (flexible, recyclable), polypropylene (PP) or modified polyethylene (PE). If we use the same subfamily (e.g., PP through TPO-based PP), TPO has the advantage of flexibility and is easier to recycle.

[0289] The dispensing valve 28 is arranged to remain in its closed state as long as the inclination angle 16 is less than 2° or 5° relative to the stable position 12. The device 100 is arranged so that the inclination does not exceed 2 degrees as long as a threshold force is not reached, for example, the threshold force corresponds to an external force (perpendicular to the surface 26) of 0.5 kg.

[0290] For the device 100 , if the external force 18 is greater than or equal to a threshold force of 0.5 kg, then the overpressure in the bag 2 and the dispensing channel 20 may open the dispensing valve 28 , thus causing fluid to be dispensed at the outlet 24 .

[0291] If the external force 18 is less than the threshold force when the dispensing head 10 is in its stable position 12, the dispensing head 10 will not tilt more than 2 degrees relative to its stable position 12. In the case, the dispensing head 10 is in the inclined position 14, and if the external force 18 is less than the threshold force, but remains below the elastic restoring force of the bag 2 (precisely the elastic restoring force of the deformable wall 4), the dispensing head 10 remains tilted in its inclined position 14.

[0292] exist Figures 1 to 3 In the case of the dispensing head 10, the dispensing head 10 comprises two separate parts 10 1 and 10 2 ,include:

[0293] - Upper part 10 1 , the dispensing valve 28 is located in the upper part, and

[0294] - Below part 10 2 , the lower part is fixed to the bag 2 and comprises a drip prevention device 30 .

[0295] The anti-drip device 30 is located between the two parts 10 1 and 10 2 and includes a valve core 30 1, the valve core is located in the distribution channel 20, wherein:

[0296] - In both parts 10 1 and 10 2 When assembled, it is arranged to be open to allow the fluid to flow to the outlet 24, and

[0297] - In both parts 10 1 and 10 2 When separated, the arrangement is closed to prevent fluid from flowing from the lower part 10 2 Flowing to the outside of the device.

[0298] The upper part 10 1 and below part 10 2 One inside the other.

[0299] The dispensing valve 28 comprises a portion 28 1 , especially the end 28 1 One of the two parts 10 of the dispensing head 10 1 and 10 2 During assembly, the valve core 30 arranged to hold the anti-drip device 30 1 In its open state, that is, in a position allowing the fluid to flow toward the outlet 24. The end 28 1 is conical so that it can open the valve 30 of the anti-drip device 30 1 , towards the inner wall of the dispensing channel 20. In the configuration, the anti-drip device 30 allows the fluid contained in the bag 2 to flow and flow toward the outlet 24.

[0300] The dispensing valve 28 comprises a portion 28 2 , which portion is sandwiched between the inner walls of the distribution channel 20.

[0301] The distribution valve 28 is located in a distribution housing 80. The housing 80 is an integral part of the channel 20.

[0302] Section 28 2 In the open and closed state, the distribution valve 28 is stationary.

[0303] In the valve 28 (and more precisely its movable part 28 4 ) is opened, the catheter 28 3 Allowing fluid to flow through the portion 28 of the housing 80 2 The fluid flows between the inner wall in the direction of the outlet 24 .

[0304] The dispensing valve 28 comprises a movable part 28 4In the closed state of the dispensing valve 28, the movable component is pressed onto the dispensing seat 105 so as to be inserted into the dispensing seat 105, and in the open state of the dispensing valve 28, the movable component is moved away from the dispensing seat 105, thereby opening the dispensing seat 105.

[0305] Section 28 4 For thin film.

[0306] The dispensing valve 28 includes the portion 28 4 , insert the portion into the upper portion 10 of the dispensing head 10 1 Part 28 4 It is the portion of the dispensing valve 28 closest to the outlet 24. The portion 28 4 The movable membrane 28 of the distribution valve 28 4 .

[0307] Section 28 4 The distribution valve 28 is movable between an open state and a closed state.

[0308] The distribution seat 105 is a lateral portion of the inner wall of the shell 80, that is, the distribution seat 105 is limited to the surface of the inner wall of the shell 80 (the surface is preferably flat (or curved)), and will not always be around the cross-section of the shell 80 (the cross-section will extend in a plane perpendicular to the elongation direction of the part of the shell 80 containing the valve 28).

[0309] In an embodiment of the manufacturing method of the device 100, the dispensing valve 28 is installed in the dispensing housing 80 by inserting the dispensing valve 28 into the upper head 10. 1 In the upper head 10 1 With lower head 10 2 At the joint between the upper head 10 1 With lower head 10 2 Before assembly.

[0310] The device 100 , in particular the upper part 10 of the dispensing head 10 1 , including the outlet 24.

[0311] The outlet 24 opens onto the exterior 100 of the device.

[0312] The outlet 24 is located at the end of the dispensing head 10, in particular at the upper part 10 of the dispensing head 10. 1 With respect to the axis A, the outlet 24 is located on the left side of the dispensing head 10 .

[0313] The contact surface 26 is around or beside the outlet 24 .

[0314] The outlet 24 is arranged to dispense fluid from a direction perpendicular to the pressure-bearing surface 26 .

[0315] The outlet 24 is arranged to dispense the fluid from a direction perpendicular to the external force 18 and from a direction opposite to the external force 18 , the force being exerted on the contact surface 26 at the level of the dispensing head 10 .

[0316] exist Figures 1 to 4 In order to fix the bag 2 on the reservoir 6, the device 100 further comprises a device 32 for screwing the bag 2 on the barrel 55, thereby fixing the reservoir 6.

[0317] The threaded connection 32 comprises threads 32 .

[0318] The bag 2 comprises an end piece 34 arranged to be embedded (eg fixed) in the reservoir 6. The end piece 34 is rigid and preferably made of PP or PE and preferably at least 8 mm long. The feed orifice 8 is located at the end of the end piece 34.

[0319] In a variant of the device 100 , the end piece 34 is pressed into the reservoir 6 , thereby fixing the bag 2 on the reservoir 6 .

[0320] On the device 100, the reservoir 6 comprises a cover 36 arranged to prevent the fluid contained in the reservoir 6 from circulating towards the bag 2 as long as the end piece 34 of the bag 2 is not pushed into the reservoir 6. Therefore, before the bag 2 is positioned on the reservoir 6, the reservoir 6 is airtight because the cover 36 has not yet been pierced.

[0321] The end piece 34 is arranged to pierce the lid 36. Therefore, in order to fix the bag 2 on the reservoir 6, it is necessary to push the end piece 34 into the reservoir 6 and then screw the device 32, which is used to screw the bag 2 to the barrel 55, so as to fix the reservoir 6. During the step of screwing the device 32 to the barrel 55, a finger 75 is placed at the bottom of the barrel 55, pressing the bottom of the reservoir 6, so as to achieve the activation of the device. In another embodiment, the reservoir 6 can include a rigid cylindrical container, in which a piston slides, and then the finger 75 pushes the piston through a hole, which is arranged at the bottom of the rigid cylindrical container.

[0322] The device 100 comprises an inlet valve 38 situated at the level of the inlet orifice 8, more precisely in the end piece 34 of the inlet seat 62, which allows the fluid contained in the reservoir 6 to flow towards the bag 2 when the inlet valve is in the open state and does not allow the flow when the inlet valve is in the closed state.

[0326] The feed valve 38 is located in the bag 2 and is arranged as follows:

[0327] - in its closed state, presses against said feed orifice 8, and

[0328] - in its open state, moved away from said feed orifice 8.

[0329] At rest, ie when the device 100 is not subject to any stress or external force 18 , the inlet valve 38 is in its closed state.

[0330] The inlet valve 38 comprises a second anti-drip means, together with the valve 38 and the inlet seat 62, inside the end piece 34. The second anti-drip means is arranged to limit the amount of product remaining in the inlet orifice 8. The second anti-drip means may be combined with the inlet valve 38. The inlet valve 38 is arranged to close if a force is exerted on the bag 2.

[0331] Preferably, even if this is not critical, the inlet valve 38 is also in its closed state at rest, ie when the device 100 is not subject to any stress or external force 18 .

[0332] The bag 2 is filled with the fluid to be dispensed, and when the volume of the bag 2 is reduced (e.g., due to an increase in the contact surface 26 and / or the application of the external force 18):

[0333] - the dispensing valve 28 (more precisely the membrane 28 4 ) leaves the dispensing seat 105 and the dispensing valve 28 is in its open state; the fluid flows out through the outlet 24 and the bag 2 is at least partially emptied,

[0334] - the feed valve 38 (especially the valve core 38 of the valve 38) 1 ) is pressed against the inner wall of the end piece 34 of the bag 2 and prevents the fluid from flowing through the feed orifice 8. The feed valve 38 is in its closed state; no (or very little) fluid can flow from the bag 2 to the reservoir 6.

[0335] The bag 2 is filled with the fluid to be dispensed, and when the volume of the bag 2 increases (e.g., by releasing the external force 18 on the contact surface 26):

[0336] - the dispensing valve 28 (more precisely the membrane 28 4 ) is pressed against the dispensing seat 105, and the valve 28 is in its closed state; the fluid cannot flow from the bag 2 to the outlet 24,

[0337] - the inlet valve 38 is "sucked in" and the valve core 38 of the valve 38 1 Moved away from the inner wall of the end piece 34 of the bag 2, facing the feed orifice 8. The valve 38 is in its open state; fluid can flow from the reservoir 6 (through the feed orifice 8) to the bag 2, thereby refilling the bag 2.

[0338] The reservoir 6 is provided with a portion 64 comprising a sealing skirt 60 provided with the lid 36 , the sealing skirt 60 being situated at the junction between the end piece 34 of the bag 2 and the upper cap of the reservoir 6 .

[0339] The portion 64 of the reservoir 6 is integral with the inner envelope of the reservoir 6. The portion 64 of the reservoir 6 is located in particular in the upper part of the reservoir 6, that is, in the housing of the reservoir 6, at the junction between the reservoir 6 and the end piece 34 of the bag 2.

[0340] The feed orifice 8 is located at the end of the end piece 34 , ie the junction between the reservoir 6 and the bag 2 .

[0347] Unless otherwise stated, throughout the description the axis A will be referred to as the axis A in the stable position 12 .

[0348] The axis A passes through the centre of gravity of the dispensing orifice 22 and the central axis of the dispensing channel 20 .

[0349] The central axis of the distribution channel 20 passes through the upper head 10 1 With lower head 10 2 The center of gravity of the joint between.

[0350] exist Figure 1 , no external forces are applied to the level of the contact surface 26. The dispensing head 10 is therefore in a stable position 12. The device 100 is therefore considered to be in a stable position 12 when the plane containing the bung 66 of the bag 2 is parallel to the plane containing the dispensing orifice 22. In this case, the axis A intersects the bung 66 of the bag 2 perpendicularly, in particular also at its centre of gravity.

[0351] exist Figure 2 , the external force 18 is applied at the level of the contact surface 26. The dispensing head 10 is therefore in an inclined position 14. The plane in which the stopper 66 of the bag 2 lies is no longer parallel to the plane in which the dispensing orifice 22 lies. The axis A passes through the centre of gravity of the stopper 66 but does not intersect it perpendicularly.

[0352] The dispensing head 10 is tilted at the tilt angle 16. Figure 2 In the embodiment, the inclination angle 16 is defined by the angle between (e.g. at the level of the engagement point on the plug 66) and:

[0353] - said axis A or the longitudinal axis of said dispenser head 10 in said stable position 12 of said dispenser head 10 , and

[0354] The axis A or the longitudinal axis of the dispensing head 10 in the inclined position 14 of the dispensing head 10 , that is to say when the dispensing orifice 22 is no longer generally parallel to the stopper 66 of the bag 2 .

[0355] The angle 16 is the same between:

[0356] the direction connecting the dispensing orifice 22 with the outlet 24 and / or the direction connecting the dispensing orifice 22 with the surface 26 in the stable position 12 of the dispensing head 10 , and

[0357] the direction connecting the dispensing orifice 22 with the outlet 24 and / or the direction connecting the dispensing orifice 22 with the surface 26 in the inclined position 14 of the dispensing head 10 .

[0358] exist Figure 2 In the embodiment, the dispensing head 10 is generally tilted in a tilted position 14 of 25 degrees (25°). However, the dispensing head 10 can be tilted in other tilted positions 14. In the described case, consider that the dispensing head 10 is tilted on the right side about the axis A of the dispensing head 10.

[0359] In fact, in addition to its stable position 12 and according to the various possible tilted positions 14, the dispensing head 10 is arranged to reach a position of maximum tilt angle relative to the stable position 12 when the tilt angle 16 is tilted by at least 20°, preferably by 30 degrees, or even by at least 45 degrees, the position of maximum tilt angle being arranged to reduce the internal volume of the bag 2, generally by at least 20%. Therefore, the dispensing head 10 cannot be tilted beyond the position of maximum tilt angle, even if the external force 18 is greater than the threshold force. If the device 100 is in its position of maximum tilt angle and an external force 18 greater than the threshold force is applied to the contact surface 26, the external force 18 may damage the device 100.

[0360] Figures 7 to 12Another embodiment of a device 700 for dispensing a fluid is described. The device 700 comprises all the elements of the device 100. Therefore, only the differences with the device 100 are described. In this section, it is considered that the axis A is defined by the axis in which the dispensing head 10 is centered.

[0361] The device 700 and the dispensing valve 28 include all the elements of the dispensing valve 28 of the device 100, but the portion 28 1 Except for this, the portion is the tapered end 28 of the dispensing valve 28 of the device 100. 1 .

[0362] In the device 700 , the deformable wall 4 of the bag 2 comprises a bellows 44 .

[0363] The bellows 44 is a bellows 44 comprising pleats. In an alternative embodiment, the device 700 may comprise at least one pleat.

[0364] The bellows 44 is cylindrical and, when the device 700 is in the stable position 12 , is on an axis colinear with the axis A. In this case, the outer wall of the bellows 44 therefore has various corrugations arranged parallel to the axis A, for example parallel to the direction of elongation of the dispenser head 10 .

[0365] exist Figure 7 , the device 700 is in a stable position 12.

[0366] The two parts 4 of the deformable wall 4 1 and 4 2 Thus, the device 700 can be tilted in different tilting positions 14 on both sides of the elongated axis of the dispensing head 10 , or even in all tilting directions of the dispensing head 10 about the axis A.

[0367] The bellows 44 is also arranged to compress when an external force 18 (comprising at least one force component parallel to the cylindrical axis of the bellows 44 and directed in the direction of the reservoir 6 ) is applied at the level of the dispensing head 10 .

[0368] The bellows 44 is made of TPO.

[0369] The device 700 comprises a locking device 50 arranged to limit and / or prevent tensioning of one side of the bellows 44 during any tilted position of the dispensing head 10. In practice, the bellows 44 of the bag 2 is located in a hard shell 50 which acts as the locking device 50. Thus, the bellows 44 is tilted in a direction which is perpendicular to the direction of the bellows 44. Figure 8 When the left side of the bellows is tilted, the portion 44 of the deformed wall of the bellows 442 Folding and overlapping, even in the section 4 1 It is slightly tensioned and will also bear against the hard shell 50. Thus, the portion 4 of the deformable wall 4 1 Extension is prevented by the hard shell 50 .

[0370] The locking device 50 is also arranged to limit and / or prevent tensioning of the bellows 44 when the bellows 44 is subjected to any tension.

[0371] Thus, in the inclined position 14, the portion 4 of the deformable wall 4 1 The distance between the two ends is equal to or only slightly greater than the portion 4 of the deformable wall 4. 1 The distance between the two ends and the stable position 12.

[0372] In the inclined position 14, the portion 4 of the deformable wall 4 2 The distance between the two ends is smaller than the portion 4 of the deformable wall 4. 2 The distance between the two ends and the stable position.

[0373] In the inclined position 14, the portion 4 of the deformable wall 4 1 The distance between the two ends is greater than or equal to the portion 4 of the deformable wall 4. 2 The distance between the two ends and the inclined position 14.

[0374] When the bellows 44 is compressed, the portion 44 of the deformable wall 4 is deformed when no force is applied to the dispenser head 10. 1 and 4 2 The distance between the two ends is smaller than the portion 4 of the deformable wall 4 1 and 4 2 The distance between the two ends.

[0375] exist Figure 8 In the embodiment, the dispensing head 10 is inclined to the left of the elongated axis of the dispensing head 10 .

[0376] Thus, in position 14, the two parts 4 of the deformable wall 4 of the bellows 44 1 With 4 2 There are asymmetric parts in between.

[0377] The bag 2 of the device 700 comprises two end pieces 34 1 and 34 2 , located at both ends of the bag 2, namely the upper end and the lower end.

[0378] The upper end of the bag 2 comprises a retaining surface 68 .

[0379] The end piece 341 and 34 2 It is cylindrical.

[0380] The bag 2 or the module 46 comprises means 32 for threading the bag 2 to the dispensing head 10. The module 46 can be mounted or threaded in the bag 2.

[0381] The threaded connection 32 comprises threads 32 .

[0382] The end piece 34 1 It is located at the upper end of the bag 2 , namely on the retaining surface 68 , and is arranged to be screwed into the dispensing channel 20 of the dispensing head 10 .

[0383] The thread 32 is located on the end piece 34 1 Therefore, the end piece 34 1 The threaded connection is on and in the dispensing head 10 .

[0384] The end piece 34 2 Located at the lower end of the bag 2, that is, on the surface of the bag 2, opposite the holding surface 68. The end piece 34 2 Arranged to be installed in the reservoir 6 and / or integrated with the reservoir 6.

[0385] The device 700 is not subjected to external forces 18, for example, Figure 7 , the retaining surface 68 is a plane.

[0386] The device 700 is arranged so that the upper end of the bag 2, and in particular the retaining surface 68, deforms as little as possible, thereby minimizing the volume of the bag 2. This may take the following form:

[0387] - a sufficiently rigid retaining surface 68 so that the end piece 34 1 At the level of the attachment, the deformation of the bag 2 caused by its tilting comprises only a deformation height less than or equal to 2 or 3 mm relative to the retaining surface 68 and the plane (or, when no force is exerted on the contact surface 26), and / or

[0388] - Strengthening the upper end of the bag 68 (via the end piece 34 1 The reinforcement can generally be carried out at the level of a plate 52 (or pusher 52) which is integral with the dispenser head 10 and which secures the bag 2 to the end piece 34, preferably by interlocking. 1 on the level of the plate 52 (or pusher 52) of the dispensing head 10, and / or

[0389] - the end piece 34 1 , including the outer diameter, is as large as the diameter of the bellows 44 , for example, at least two-thirds of the diameter of the bellows 44 .

[0390] The dispensing head 10 is a single piece, divided into:

[0391] - a middle part (preferably cylindrical), on said axis A and in the centre of which said distribution channel 20 is arranged,

[0392] - an applicator, carried by the middle portion and comprising at least a curvilinear shape (e.g. a curve), including said contact surface 26 and / or said outlet 24. For said device 700, said curvilinear shape is spherical and extends over said entire surface of said applicator;

[0393] - a portion in the form of a plate 52 , carrying a middle portion and situated on the end of the dispensing head 10 , that is to say the end of the dispensing head 10 facing the holding surface 68 of the bag 2 .

[0394] Said portion takes the form of a plate 52 and, facing said retaining surface 68 , comprises said pusher 52 .

[0395] The dispensing channel 20 passes through all parts of the dispensing head 10 and is located on the central axis, or the axis A, of the dispensing head 10 .

[0396] The applicator, ie the spherical portion of the dispensing head 10 , is located at the upper end of the dispensing head 10 and therefore comprises the outlet 24 through which the fluid of the device 700 flows out.

[0397] The device 700 and the outlet 24 are arranged to dispense fluid in the direction of elongation of the dispensing head 10 .

[0398] The contact surface 26 of the dispensing head 10, more precisely the contact surface of the applicator, extends over the entire circumference of the curvilinear shape of the applicator, and therefore over the entire spherical portion of the dispensing head 10. In this way, the device 700 comprises an extended contact surface 26, and it is possible to apply the external force 18 from various positions of the applicator of the dispensing head 10. Thus, the device 700 can be used for different forms of application of the external force 18.

[0399] exist Figure 7 In this case, no external force 18 is applied to the contact surface 26.

[0400] The longitudinal direction of the dispenser head is defined by the axis A, which is located, for example, in the middle of the dispenser head 10 .

[0401] When the dispensing head 10 is in its stable position 12 , the dispensing head 10 and the reservoir 6 are axially aligned in the longitudinal direction, ie the dispensing head 10 and the reservoir 6 have coaxiality.

[0402] When the dispensing head 10 is in its stable position 12 , the dispensing head 10 and the bag 2 are also axially aligned in the longitudinal direction, ie the dispensing head 10 and the bag 2 are coaxial.

[0403] The dispensing head 10 is arranged to be inclined, exerting the external force 18 on the opposite side at the level of the contact surface 26 .

[0404] When the external force 18 is applied to the device 700 , on the contact surface 26 , the arrangement of the device 700 , for example with the bellows 44 and the spherical contact surface 26 , causes the dispensing head 10 and the bag 2 to follow the same tilting movement.

[0405] exist Figure 8 In the embodiment, the external force 18 is applied to the right side of the contact surface 26. The dispensing head 10 and the bag 2 are tilted to the left of the elongation axis of the dispensing head 10, for example, to the left of the axis A.

[0406] The dispensing head 10 is provided with the pusher 52, which is arranged as follows:

[0407] - pressed against the retaining surface 68 of the bag 2, preferably against the retaining surface 68 of the bellows 44, and

[0408] - Keeping the retaining surface 68 fixed relative to the dispensing head 10 .

[0409] exist Figure 8 In the case of, when the dispensing head 10 is tilted, the locking device 50 is pressed against the pusher 52, and the pusher 52 itself is pressed against the holding surface 68 of the bag 2. Figure 7 and Figure 8 In the embodiment, the retaining surface 68 and the pusher 52 remain assembled, that is, the locking device 50 is clamped on the housing 70 accommodating the reservoir 6.

[0410] The housing 70 may be made of metal and / or polymer.

[0411] The locking means 50 , that is to say the rigid shell 50 , are arranged to define and / or prevent tensioning of one side of the bag 2 , thus defining the inclination of the dispensing head 10 .

[0412] The locking device 50 is cylindrical.

[0413] The device 50 comprises a hole for inserting said dispensing head 10 .

[0414] The dispensing head 10 is arranged in the hole of the locking device 50. Therefore, the hole of the locking device 50 is around the middle of the dispensing head 10. Therefore, the hole of the locking device 50 includes an inner diameter, which is larger than the middle of the dispensing head 10, thereby tilting the dispensing head 10 while restraining the dispensing head.

[0415] Thus, the inner diameter and / or outer diameter of the locking device 50 may be selected such that a maximum tilt angle is defined.

[0416] The locking device 50 comprises threaded connection means 102 on the outer wall for threading the locking device 50 to the hard shell 70 comprising the reservoir 6. The hard shell 70 is arranged to accommodate the entire volume of the reservoir 6.

[0417] The reservoir 6 has parts including:

[0418] an inlet valve 38 situated on an inlet seat, said valve 38 being situated at the junction of the internal volume of the bag 2 with the internal volume of the reservoir 6, and

[0419] a cap 40 provided with a cover 42, said cap 40 being situated at the junction of the internal volume of the bag 2 and the dispensing channel 20 and being arranged to be fixed to the end piece 34 1 (in the end piece 34 1 ), and

[0420] A connecting element 46 for connecting the inlet valve 38 to the cap 40 , the connecting element 46 being arranged to deform during deformation of the bag 2 .

[0421] The portion of the reservoir 6 having the cap 40 further comprises the inlet valve 38 situated at the level of the inlet seat 62 , the valve 38 being situated at the junction of the internal volume of the bag 2 with the internal volume of the reservoir 6 .

[0422] The cap 40 further comprises an insertion device arranged to push the inlet valve 38 into the end piece 34 2 More precisely, the end piece 34 of the bag 2 is pushed into 2 internal.

[0423] These insertion means are connected to the feed valve so that it is inserted into the bag, forming a supply element, preferably connected to the end opposite the feed valve, and in order to fix it, more precisely by fixing it to the bag, at the upper end piece 34 1 and / or lower end piece 342 On the edge of.

[0424] The inlet valve is located in the lower end piece.

[0425] The cover of the cap is located within the upper end piece.

[0426] The connecting element connects the inlet valve and the insertion device.

[0427] exist Figure 7 , Figure 8 and Fig. 9 In this case, the feed valve 38 , the cap 40 and the connecting element 46 form a single and unified connecting piece 701 , the cap having the cover 42 .

[0428] Thus, with respect to the end piece 34 of the bag 2 1 and 34 2 :

[0429] - the end piece 34 of the bag 2 1 comprising an inner diameter, being hollow (and cylindrical), arranged to receive said cap 40 of said connector 701, and

[0430] - the end piece 34 of the bag 2 2 It comprises an inner diameter, is hollow (and cylindrical), and is arranged to receive the inlet valve 38 of the connector 701 (and thereby be secured to the upper end of the reservoir 6).

[0431] exist Figure 7 and Figure 8 In this case, the connecting element 46 is flexible and is located within the internal volume of the bag 2.

[0432] The device 700 further comprises a perforator 48, which is located in the dispensing head 10 and is arranged to penetrate the cover 42 of the cap 40, which is in the dispensing seat, when the device 700 is assembled. Thus, the perforator 48 mainly comprises one end, with an acute angle, facing the cover 42 of the cap 40 and arranged to pierce the cover 48 of the cap 40.

[0433] exist Figures 7 to 9 In this case, after the bag 2 is mounted on the reservoir 6, the connecting element 46 of the connecting piece 701 is flexible or fragile.

[0434] In the case of the device 700, the connecting element 46 is flexible. In this way, at each tilt of the dispensing head 10, the connecting element 46 follows the movement of the bag 2 and does not break. The bag 2 is no longer aligned with the central axis of the reservoir 6 and the axis A. Note that the bag 2 can be tilted relative to the stable position 12, but also compressed along the axis A (including the axis A for the device 100), even in the stable position 12. The device is arranged to dispense the product by tilting the dispensing head 10 relative to the stable position 12, but the device is also arranged to dispense the product by compressing the dispensing head 10 along the axis A.

[0435] The device 700 and the reservoir 6 are formed as a single piece.

[0436] The reservoir 6 and the bag 2 of the device 700 are formed as a single piece.

[0437] The reservoir 6 of the device 700 comprises a bellows 6 of the reservoir 6 1 Thus, the reservoir 6 of the device 700 comprises an outer wall comprising two parts:

[0438] - Part 1 6 1 , the first part comprises the bellows 6 of the reservoir 6 1 ,

[0439] - Part 2 6 2 The second part is located in the bellows 6 of the reservoir 6 1 Below.

[0440] When the dispensing head is in the stable position 12 ( Figure 7 ), the bellows 6 of the reservoir 6 (preferably cylindrical) 1 The axis A is the center. Therefore, when the dispensing head 10 is in a stable position, the bellows 6 of the reservoir 6 1 The dispensing head 10 includes parallel corrugations 6 which are located on its outer wall and are continuous and parallel to the axis A (that is, parallel to the elongation direction of the dispensing head 10). 1 .

[0441] The reservoir 6, more precisely the bellows 6 of the reservoir 6 1 , arranged to be compressed in a direction parallel to said axis A and in a direction starting from said reservoir 6 towards said bag 2 .

[0442] The reservoir 6, more precisely the portion 6 of the reservoir 6 2Arranged to compress towards the inside of the reservoir 6 , preferably in a direction perpendicular to the axis A and in a direction 90 starting from the outer wall of the reservoir 6 towards the axis of the reservoir 6 (eg the axis A).

[0443] Thus, the reservoir 6 comprises a groove 92 or a rigid member 92 on its outer wall, in particular in the portion 6 of the reservoir 6. 2 On the other hand, it is arranged close to the interior of the reservoir 6. Therefore, the groove 92 is arranged to compress the reservoir 6 in the direction perpendicular to the axis A and in the direction 90, thereby reducing the volume of the fluid contained in the reservoir 6.

[0444] The groove 92 of the reservoir is located at the bellows 6 of the reservoir 6 1 Below, more precisely in said portion 6 of said reservoir 6 2 middle.

[0445] The reservoir 6, more precisely the portion 6 of the reservoir 6 2 , is arranged to enter the reservoir 6 (more precisely the bellows 6 1 preferably in a direction parallel to said axis A, such as Fig.11 shown.

[0446] exist Fig.11 and Fig.10 In the drawings, the device 700 is in a stable position 12. The locking means 50, the housing 70 of the reservoir 6 and the dispensing head 10 are not shown in these figures.

[0447] The bag 2 and the reservoir 6 of the device 700 are integrated with each other so as to form a single piece. The parts are preferably made by blowing or 3D printing.

[0448] More precisely, Fig.10 and Fig.11 The device 700 is shown comprising the bag 2 and the reservoir 6 to be blown after complete use or after no use of the device 700.

[0449] In fact, Fig.10 In the , you can see:

[0450] - compress the upper part 6 1 (e.g., the bellows 61 of the reservoir 6), comprising corrugations parallel to the central axis of the device 1000. Fig.10 In, with Figure 7 , Figure 8 and Fig. 9 In comparison, the spacing between the corrugations of the reservoir 6 has been reduced. Fig.10 The bellows 6 of the reservoir 6 1 The length is less than Figure 7 , Figure 8 and Fig. 9 The bellows 6 of the reservoir 6 1 Therefore, the bellows 6 of the reservoir 6 1 compression.

[0451] - The following part 6 2 The smooth wall comprises a smooth wall, but the smooth wall is constructed by a reinforcement 92 (also referred to as a groove 92), and the smooth wall is arranged so that the portion 6 of the reservoir 6 2 Axially deformed in order to avoid folding, for example, in the horizontal clamping of the wall of the reservoir 6. The shape of the longitudinal "embossed" reinforcement 92 is achieved by Fig.12 Part 6 of the reservoir 6 2 and cross-sectional illustrations.

[0452] Therefore, after several dispenses of the fluid, Fig.10 The reservoir 6 is shown in reduced form. Use of the device 700 is incomplete, that is to say the bag 2 of the reservoir 6 and the device 700 still contain fluid.

[0453] exist Fig.11 In the embodiment, the use of the device 700 is complete, that is, the reservoir 6 of the device 700 no longer contains any fluid. A certain amount of fluid may still be in the bag 2.

[0454] exist Fig.11 In the embodiment, the intervals between the corrugations of the reservoir 6 are Fig.10 The spacing between the corrugations is the same. However, the portion 6 of the reservoir 6 2 has been compressed in the direction of said axis A.

[0455] In the case of the device 700, if the reservoir 6, in particular the portion 6 of the reservoir 6 1 including an outer diameter (which is larger than the portion 6 of the reservoir 6 2 OD), then part 6 2 Arranged to fit inside the reservoir 6 .

[0456] Thus, after each tilting of the dispenser head 10, the internal volume 6 of the reservoir is reduced, preferably compressed, so that the lower part 6 of the reservoir 6 is 2 The upper portion 6 near the reservoir 6 1 , and / or in section 6 2 Upper radial compression.

[0457] In fact, Fig.11 In the lower part 6 of the reservoir 6 2 compressed, and in the upper portion 6 of the reservoir 6 1 Inwardly folded so as to optimize the emptying of the fluid contained in said reservoir 6 .

[0458] Figures 13 to 16 A further embodiment of a device 1300 for dispensing a fluid is shown. Only the differences with respect to the device 700 described are described.

[0459] The device 1300 and the dispensing valve 28 are identical to the dispensing valve of the device 700 .

[0460] The device 1300 includes:

[0461] - a reservoir 6 which is located in a hard shell 70,

[0462] - a bag 2, which is carried by a reservoir 6,

[0466] A cap 74 for covering the dispensing button 72 , the cover 94 , the dispensing head 10 , the bag 2 and the reservoir 6 .

[0467] When the device 1300 is no longer used to dispense fluid, the cap 74 is arranged on the hard shell 70. The entire internal volume of the reservoir 6 is within the hard shell 70.

[0468] The hard shell 70 includes an inner wall 70 1 .

[0469] The hard shell 70 may be made of metal and / or glass, and / or wood.

[0470] The device 1300, and more precisely the dispensing head 10, has a position of maximum inclination.

[0471] The device 1300 comprises the cover 94 arranged to delimit and / or prevent the dispensing head 10 from tilting below the position of maximum tilt angle. Thus, the cover 94 prevents the tilting of the dispensing head 10 when the dispensing head has reached its position of maximum tilt angle.

[0472] The cover 94 includes a threaded connection device 104 for threading the cover 94 onto the hard shell 70 , thereby holding the dispensing head 10 and fixing the bag 2 and the reservoir onto the hard shell 70 .

[0473] For the device 700, the cover 94 comprises a hole and is located on a central axis of the cover 94, which is colinear with the axis A. The hole of the cover 94 is arranged to pass through the dispensing head 10, passing inside the hole of the cover 94. Therefore, the diameter of the hole in the cover 94 is greater than the diameter of the dispensing head 10. The maximum tilt angle position of the dispensing head 10 is defined by the diameter of the hole in the cover. In a variant of the device 1300, the diameter of the hole of the cover 94 is arranged so as not to prevent the tilting of the dispensing head 10.

[0474] The dispensing button 72, the dispensing head 10 1 Including outer wall and inner wall.

[0475] The dispenser head 10 comprises, on its outer wall, means 106 for threading the portion 10 of the dispenser head 10 2 , including the channel 20 threadedly connected to the dispensing button 72, generally threadedly connected to the inner wall of the dispensing button 72.

[0476] The dispensing button 72 further comprises a hole 73, which is located on the upper wall of the dispensing button 72 and passes through the outer wall and the inner wall of the dispensing button 72. When the device 1300 is assembled, that is, when the dispensing button 72, the cover 94, the dispensing head 10, the bag 2, the reservoir 6 and the hard shell 70 are assembled together, the hole 73 is arranged so that it is located on the outlet 24 of the dispensing head 10. Therefore, when the part 10 is assembled, the dispensing button 72, the cover 94, the dispensing head 10, the bag 2, the reservoir 6 and the hard shell 70 are assembled together. 2 Fixed to the dispensing button 72 , the fluid can flow out through the outlet 24 and through the hole 73 of the dispensing button 72 of the dispensing head 10 .

[0477] When the dispensing button 72 is fixed by the threaded connection device 106 , the outer wall of the dispensing button 72 of the dispensing head includes the contact surface 26 .

[0478] The dispensing button 72 is fixed to the portion 10 2 1. The dispensing button adopts various positions, namely the stable position 12 and / or the inclined position 14 of the dispensing head 10 assembly.

[0479] The reservoir 6 comprises a cap 96 arranged to at least partially delimit the reservoir 6. The cap 96 comprises two parts:

[0480] - Platform 98, and

[0481] A trunk 76 which is located in the reservoir 6 and carries the platform 98 of the cap 96 .

[0482] The platform 98 and the trunk 76 are integrated together.

[0483] The stem 76 is cylindrical and is located on the central axis of the dispensing channel 20 , which is colinear with the axis A. The stem 76 and the dispensing channel 20 are therefore coaxial at the position 12 . The stem 76 is also located on the central axis of the deformable envelope 56 of the reservoir 6 .

[0484] The platform 98 of the cap 96 comprises a flat rigid wall having at each end two angled edges 98 oriented towards the interior of the reservoir 6 1 .

[0485] The reservoir 6 comprises the deformable envelope 56 which at least partially delimits the internal volume 6 of the reservoir, the deformable envelope 56 comprising continuous corrugations 56 radially around the axis A. 2 .

[0486] The deformable envelope 56 of the reservoir 6 thus comprises three parts:

[0487] - Upper part 56 1 The upper portion includes an edge, preferably smooth, and extending along the inner wall 70 of the hard shell 70. 1 go ahead,

[0488] - Lower part 56 2 , the lower portion comprises radially continuous corrugations 56 2 ,

[0489] -Bottom 56 3 , the bottom carries the corrugation 56 2 , and includes a filling orifice 82 .

[0490] The bottom 56 3 For a rigid wall, that is, more than including the corrugation 56 2 The lower part 56 2 More rigid.

[0491] The filling orifice 82 comprises a central axis centered on the central axis of the reservoir 6 , ie the axis A. The filling orifice 82 and the reservoir 6 are therefore coaxial and the filling orifice 82 is coaxial with the stem 76 of the cap 96 of the reservoir 6 .

[0492] The filling orifice 82 is circular and has a diameter equal to the outer diameter of the trunk 76 .

[0493] The filling orifice 82 is arranged to be fixed together and / or embedded in the stem 76 of the cap 96 of the reservoir 6 when the device 1300 is assembled, more precisely the reservoir 6 is assembled. In this way, the stem 76 is assembled in the filling orifice 82 and after filling the reservoir 6 with the fluid, the stem 76 is arranged to collect air bubbles (not shown) and collect them in the stem 76. This prevents the bubbles from increasing in the reservoir 6 and then in the bag 2.

[0494] The portion 56 of the reservoir 6 having the filling orifice 82 3 Including sealing closure device 82 1 The sealing device 82 1 Including sealing skirt 82 1 .

[0495] The filling orifice 82 is arranged to be closed by the cap 96 of the reservoir 6, in particular by the stem 76. The portion 56 of the deformable envelope 56 of the reservoir 6 3 Arranged to be separated from the cover 94 , in particular from the trunk 76 , for example by means of a suction cup during a filling phase of the device 1300 .

[0496] The deformable wall 56 of the reservoir is fixed or welded to the cover 94 of the reservoir 6 .

[0497] The corner edge 98 of the platform 98 of the reservoir 6 1 The deformable wall 56 is arranged to fix the reservoir 6. In particular, the corner edge 98 of the platform 98 of the reservoir 6 1 Press to the upper end of the wall 56, against the inner wall 70 of the hard shell 70 1 .

[0498] Each time the volume of the deformable envelope 56 is reduced, the deformable envelope 56 is arranged to fold towards the platform 98 .

[0499] The deformable envelope 56 is arranged to be folded around the trunk 76 each time the volume of the deformable envelope 56 is reduced.

[0500] In fact, Fig.13 and Fig.14In the embodiment, the device 1300 is completely filled. Thus, the reservoir 6 has its maximum internal volume, the reservoir containing all the fluid of the device 1300. In this case, the continuous corrugations 56 of the deformable envelope 56 of the reservoir 6 2 Relative to the central axis of the trunk 76 , for example, radially about the axis A.

[0501] exist Fig.15 In the embodiment of the present invention, almost all the fluid contained in the deformable envelope 56 of the reservoir 6 has been dispensed. The deformable envelope 56 is folded toward the platform 98. Therefore, the corrugations 56 of the deformable envelope 56 are 2 has moved toward the trunk 76 and formed the corrugations 56 2 , the corrugations are substantially radial around the axis of the trunk 76.

[0502] The smooth edge 56 of the deformable envelope 56 1 The cap 96 arranged close to the reservoir 6, in particular the cap 96 of the platform 98, is arranged so that each time the volume of the fluid contained in the reservoir 6 is reduced, the smooth edge is substantially pressed against the inner wall 70 of the hard shell 70. 1 superior.

[0503] Such a configuration makes it possible to consume as much as possible the volume of fluid contained in the reservoir 6 and to optimize the return of the fluid:

[0504] - by increasing the area of ​​the deformable wall 56 of the reservoir 6, in particular by the corrugations 56 of the deformable wall 56 2 ,and

[0505] - By arranging the deformable wall 56 so that each time the volume of the cap of the reservoir 6 is reduced, it matches as closely as possible the rigid shape of the reservoir, in particular the cover 96 .

[0506] Said device 1300 for dispensing a fluid comprises said bag 2 having an internal volume arranged to contain said fluid, said internal volume being at least partially delimited by said deformable wall 4 .

[0507] The bag 2 is formed by a bottom wall 21 and the flexibly deformable wall 4 .

[0508] The bottom wall 21 and the deformation wall 4 face each other.

[0509] The wall 4 forms a concave skirt and has an upper part and a lower part.

[0510] The deformation wall 4 (more precisely, the lower portion thereof) is fixed or welded to the bottom wall 21 .

[0511] The bottom wall 21 preferably has a planar or substantially planar shape.

[0512] The bottom wall 21 is a rigid wall, ie, more rigid than the wall 4 .

[0513] For example, the deformation wall 4 is a thin wall, and for example, the bottom wall 21 is a thicker wall than the wall 4 .

[0514] For example, the bottom wall 21 and the deformation wall 4 are made of polypropylene (PP).

[0515] The deformable wall 4 is preferably made of PP, by polymer or plastic additives (e.g., Vistamaxx TM 6202) in order to reduce its hardness so that the hardness of the wall 4 is less than 80 Shore A. Thus, too great a fineness and weakness of the wall 4 is avoided.

[0516] The bottom wall 21 is parallel to the platform 98. More precisely, the bottom wall 21 is fixed to the platform 98 of the cap 94. In a variant of the device 1300, the bottom wall 21 and the platform 98 are in a single piece.

[0517] The feed orifice 8 is located at the level of the bottom wall 21 and pierces the bottom wall 21 and the platform 98 , connecting the reservoir 6 with the bag 2 .

[0518] The deformable wall 4 of the bag 2 comprises a weakened area 78 and / or a joint 78 arranged to be tilted into position 14 , the dispensing head 10 being tilted but stable without external forces 18 .

[0519] These weakened areas 78 correspond to areas 78 where the deformable wall of the bag 2 is thinner than the rest of the deformable wall 4 .

[0520] When the dispensing head 10 is in the inclined position 14, the weakened area 78 of the deformable wall 4 is arranged to press against and / or be close to the bottom wall 21 of the bag 2, thus forming the inclined position 14, the preferred position of the dispensing head 10 (and being stable).

[0521] As long as no second external force is applied to the contact surface 26, the device 1300 maintains and holds the tilted position 14 but the dispensing head 10 is stable. However, the second external force must be applied to the other side to which the external force 18 has been applied in order to keep the dispensing head 10 in its tilted position 14.

[0522] In all cases, the deformation force is harder at the beginning of the tilting and then reaches more easily or automatically a preferred position, within an angle of 5 degrees, thus allowing for dosing.

[0523] In fact, Fig.15 In the embodiment of the present invention, the external force 18 is applied to the right side of the dispensing head 10 relative to the central axis of the dispensing channel 20. The dispensing head 10 and the bag 2 remain in the inclined position 14, but are stable on the left side. Therefore, in order to return the device 1300 to its initial stable position, that is, before any external force 18 is applied (for example, when the dispensing head 10 is coaxial with the reservoir 6), the second external force must be applied to the left side of the dispensing head 10, for example, the inclined position 14 is on the side.

[0524] In an embodiment of the method of assembling the apparatus 1300, Fig.16 As shown in FIG. 5 , the deformable wall 56 of the reservoir 6, in particular the portion 56 3 The reservoir 6 is filled with fluid and closed by the cap 96 by moving the deformed wall 56 of the reservoir 6 towards the interior of the reservoir 6, in particular the portion 56. 3 The reservoir 6 includes a sealing skirt that can seal the portion 56. 3 For example, the bottom of the reservoir 6 is mounted in the cap 96. The deformable wall 56 of the reservoir 6 comprises the sealing skirt and is made of the same material.

[0525] The sealing skirt is larger than the portion 56 of the deformable wall 56. 2 More rigid.

[0526] In the case of assembling the device 1300 by blow molding, the sealing skirt can be made of a more rigid material since the thickness of the deformable wall 56 can be reduced.

[0527] In the case of the device 1300 mounted by injection: the thickness of the deformable wall varies between 0.4 mm and 0.5 mm. In this case, a flexible material is used to design the reservoir, in particular the deformable wall 56. The sealing skirt is designed with a material that is more rigid than the deformable wall 56 material.

[0528] In variations of these devices 100, 700 and 1300, there may be two fluids contained in two separate reservoirs 6. These devices 100, 700 and 1300 may have a preferential inclination for each fluid, and / or a third inclination arranged to mix the fluids. For example, the third inclination may be a pressure 18 parallel to the direction of elongation of the dispensing head 10 or colinear with the axis A.

[0529] Figure 17 to Figure 18Another embodiment of a device for dispensing a fluid 1700 is shown. Only the differences from these devices 100, 700 and 1300 will be described.

[0530] The apparatus 1700 for dispensing the fluid comprises:

[0531] - Bag 2, which bag includes inner bag 2 1 and outer bag 2 2 , the inner bag 2 1 At least partially located in the outer bag 2 2 inside, the inner bag 2 1 and outer bag 2 2 Both have an internal volume arranged to contain the fluid, the outer bag 2 2 The inner volume of the inner bag 2 is at least partially delimited by a movable wall 3, which is arranged to reduce the size of the inner bag 2 by deforming and / or moving when a pressure 18 is applied. 1 The internal volume and the outer bag 2 2 The internal volume of

[0532] - an outlet 24 arranged to distribute said fluid.

[0533] The inner bag 2 1 The interior volume is defined at least in part by:

[0534] - a piston, which is integral with the connecting wall 7 and which at least partially delimits the outer bag 2 2 The internal volume of

[0535] A housing 9 of the piston 5 , which is arranged to accommodate the piston 5 and to guide the piston 5 during its axial movement 11 inside the housing.

[0536] The device 1700 is arranged to direct the fluid according to a circuit comprising:

[0537] - a first path, which passes through at least the connecting hole 13 from the outer bag 2 2 The inner side passes through the inner bag 2 1 inside, and / or into the inner bag 2 1 The piston 5 inside is used to connect the outer bag 2 2 The internal volume of the inner bag 2 1 the inner side and / or the piston 5, and

[0538] - a second path, which is from the inner bag 2 1 The inner side of the piston 5 and / or the piston 5 pass to the outlet 24.

[0539] The device 1700 also includes a feed port 8 for connecting the reservoir 6 to the outer bag 2 2 internal volume.

[0540] pass Fig.17 The term "volume of bag 2" means the volume of the inner bag 2 1 The internal volume of the outer bag is 2 2 The sum of the internal volumes.

[0541] The pocket 2 is delimited by the movable wall 3 , the connecting wall 7 and the bottom wall 21 .

[0542] The device 1700 further comprises a braking device 15, which is arranged to prevent the axial movement 11 of the piston 5 in the housing 9 when the movable wall 3 is subjected to a pressure 18 (hereinafter referred to as external force 18) less than a threshold force, thereby reducing the pressure of the inner bag 2. 1 The internal volume and the outer bag 2 2 The device 1700 comprises means for "free" movement, wherein the internal volume of the bag 2 is reduced when the connection hole 13 is closed, without overpressure stress of the liquid (acting as a feed valve). During the step, the fluid is pumped into the reservoir 6 through the orifice 8, the bag 2 is deformed, and the piston 5 rubs against the inner wall of the shell 9, and / or means 65 for guiding the piston 5 in the shell 9, the step is used for the acceleration / propulsion of the pressure-bearing surface 26. Finally, the device 1700 comprises means for increasing the pressure: after the connection hole 13 is closed, the piston presses the product against the inner bag 2 as quickly as possible. 1 Preferably, during the pressure rise, the pressure is less than the threshold force.

[0543] Thus, the piston 5 and the housing 9 are arranged so that upon application of the force 18 the piston 5 performs three stages of movement within the housing 9:

[0544] 1 a blocking phase, during which the piston 5 does not move beyond the device 15 as long as the force 18 is less than the threshold force, and then moves beyond the device 15 as soon as the force 18 is greater than the threshold force;

[0545] 2 the free movement of the piston 5 in the housing 9, once the piston 5 passes over the means 15 (acceleration during closing of the orifice 13 in the space between the piston and the housing), which generally corresponds to a movement of the piston 5 in its housing 9 of at least 0.5 mm or even 1 mm, making it possible to provide a push or acceleration for the threshold force (kinetic energy), and

[0546] 3 compression stage, including the pressure in the bag 21 This is done after the hole 13 is closed.

[0547] The most important are stages 2 and 3, stage 1 is optional and / or the return force may be restored by deformation or movement of the outer bag.

[0548] The axial movement 11 of the piston 5 takes place along the center axis of the piston 5 .

[0549] The device 1700 comprises a pressure-bearing surface 26, also called a contact surface 26, which is arranged to reduce the pressure of the inner bag 2 when the pressure 18 is applied and by means of the dispensing head 10. 1 And outer pocket 2 2 The internal volume of the movable wall 3 is increased by deformation and movement.

[0550] The pressure-bearing surface 26 is integrated with the dispensing head 10 and preferably comprises at least a part of the dispensing head 10 .

[0551] The device 1700 comprises the outlet 24 .

[0552] The outlet 24 opens out on the exterior 1700 of the device.

[0553] The outlet 24 is located on the dispensing head 10 .

[0554] The outlet 24 is arranged to dispense the fluid in a direction perpendicular to the direction of movement of the dispensing head 10 .

[0555] The dispensing head 10 is arranged so as to allow a translational movement.

[0556] The outlet 24 is arranged to dispense fluid in a direction parallel to the elongate axis of the dispensing channel 20 .

[0557] The device 1700 comprises a dispensing orifice 22 for connecting the bag 2 with the dispensing channel 20 .

[0558] The dispensing valve 28 is within the dispensing channel 20 of the device 1700 .

[0559] The dispensing channel 20 of the device 1700 comprises an internal volume, which is arranged to include (or accommodate) only the dispensing valve 28. Therefore, only the dispensing valve 28 is included in the dispensing channel 20.

[0560] The device 1700 includes the dispensing valve 28, which is located in the dispensing channel 20 and allows the fluid to be dispensed from the inner bag 20 when the dispensing valve is in the open state. 1The liquid flows from the inner side of the inner bag 2 to the outlet 24, flows through the dispensing orifice 22 and the dispensing channel 20 (especially through the housing 80), and when the dispensing valve is in the closed state, the fluid is not allowed to flow from the inner bag 2 1 The interior of the liquid flows toward the outlet 24 , through the dispensing orifice 22 , and through the dispensing passage 20 (more precisely, through the housing 80 ).

[0561] The dispensing head 10 is integrated with the bottom wall 21 , which is achieved by injection molding or bi-injection of the dispensing head 10 on the bottom wall 21 .

[0562] The dispensing channel 20 therefore comprises and / or is formed by the wall of the dispensing head 10 and the upper wall of the bottom wall 21 .

[0563] The dispensing head 10 comprises a sprayer 10 .

[0564] The dispensing head 10 is located outside the bag 2 .

[0565] The dispensing head 10 is arranged to move at least according to the translational movement when a pressure force 18 is applied to the pressure-bearing surface 26. The translational movement of the dispensing head 10 is in the same direction as the axial movement 11 of the piston 5, but opposite thereto.

[0566] The components of the dispensing head 10 are arranged to at least partially move along the outer bag 2 when the pressure 18 is applied. 2 The outer wall of the outer bag 2 slides, thereby 2 The movable wall 3 moves and / or deforms.

[0567] The pressure-bearing surface 26 is arranged to reduce the pressure of the inner bag 2 when pressure is applied. 1 and outer bag 2 2 of the interior volume, which is achieved by deforming the movable wall 3, more precisely by pressing it in the direction of the wall of the joint 7.

[0568] The deformable movable wall 3 has shape memory. When the wall 3 is not subjected to any external stress, it continues or maintains its shape, such as Fig.17 As described above, the inner bag 2 1 and outer bag 2 2 Maximize the volume.

[0569] The pressure-bearing surface 26, the exterior 1700 of the device accessible by a user's hand, has a minimum surface area of ​​10 square millimeters.

[0570] The housing 9 of the piston 5 is at least partially delimited by the bottom wall 21. Part of the bottom wall 21, that is, the portion of the bottom wall 21, contacts the dispensing channel 20, and the bottom wall is integrated with the housing 9 of the piston 5.

[0571] The bottom wall 21 at least partially defines the outer bag 2 2 volume.

[0572] The connecting wall 7 at least partially delimits the piston 5 .

[0573] The bottom wall 21 at least partially delimits the housing 9 of the piston 5 .

[0574] The distance between the wall 7 and the wall 21 defines the inner bag 2 1 volume.

[0575] In the device 1700 , the braking device 15 is integrated with the housing 9 of the piston 5 and preferably comprises at least one lug 17 which is inclined towards the inside of the housing 9 .

[0576] The device 1700 comprises a lug 17 .

[0577] In the device 1700, the movable wall 3 is separated from the connecting wall 7. The connecting wall 7 is arranged to delimit the internal volume of the bag 2 and the internal volume of the cap of the reservoir 6.

[0578] The connecting wall 7 comprises a substantially planar shape. In the case of the device 1700 , the connecting wall 7 is rigid, ie more rigid than the deformable wall 3 of the bag 2 .

[0579] The movable wall 3 is located between the bottom wall 21 and the connecting wall 7 .

[0580] The connecting wall 7 has the same rigidity as the bottom wall 21 .

[0581] The connecting wall 7 is fixed to the movable wall 3 of the bag 2 .

[0582] The movable wall 3 is fixed to the bottom wall 21 of the bag 2 .

[0583] The deformable wall 3 is flexible.

[0584] The movable wall 3 is generally made of TPO.

[0585] The piston 5 is partially delimited by the connecting wall 7 .

[0586] The piston 5 is fixed to the connecting wall 7 by welding and / or casting.

[0587] The piston 5 is integrated with the flat portion of the connecting wall 7 .

[0588] The connecting wall 7 is made of PP.

[0589] The piston 5 is made of the same material as the connecting wall 7. In the device 1700, the piston 5 and the connecting wall 7 are formed in one piece.

[0590] Therefore, the piston 5 is located between the flat portion of the connecting wall 7 and the housing 9 of the piston 5 .

[0591] The housing 9 of the piston 5 is located between the piston 5 and the distribution channel 20 .

[0592] The piston 5 is hollow and cylindrical and comprises an outer diameter which is delimited by the connecting wall 7 .

[0593] The outer diameter of the piston 5 comprises an increase in its diameter, on the end of the piston 5, facing the housing 9 of the piston 5. The arrangement makes it possible to form a sealing linear annular contact during the pressing phase, that is, when the dispensing head 10 is driven by the translational movement, thereby reducing the volume of the bag 2. This may, among other things, increase the sealing performance of the device 1700. A low rotational movement (for example using the ball joint type) can optionally be used to supplement the translational movement.

[0594] The device 1700 further comprises a feed opening 8 for connecting the feed channel 78 and / or the reservoir 6 to the outer bag 2 2 volume.

[0595] The device 1700 includes the reservoir 6. The reservoir 6 is connected to the outer bag 2 through the feed orifice 8. 2 The reservoir 6 comprises an internal volume arranged to contain the fluid.

[0596] The device 1700 is arranged to guide the fluid along the second path, which occurs each time the pressure 18 of the movable wall 3 is greater than the threshold force, and / or the inner bag 2 1 and outer bag 2 2 Each time the internal volume of the bag 2 decreases, the connecting hole 13 is closed, thus causing the piston 5 to move in the housing 9. The movement of the piston 5 in the housing 9 presses against the product in the volume of the bag 2.

[0597] After (sufficient) pressure is applied to the movable wall 3, the connecting hole 13 is closed, thus forming the inner bag 2. 1 of the feed valve.

[0598] The apparatus 1700 is arranged to direct the fluid along a first path:

[0599] - after each end of a pressure 18 greater than the threshold force, that is, when a pressure 18 greater than the threshold force is no longer exerted on the movable wall 3, and / or

[0600] -The inner bag 2 1 and outer bag 2 2 Each time the internal volume of the outer bag 2 increases, the connecting hole 13 is opened, that is, the piston 5 in the housing 9 returns to the outer bag 2 2 , and enter the outer bag 2 2 middle.

[0601] The connecting hole 13:

[0602] - forming a joint between one end of the piston 5 and one end of the housing 9 of the piston 5, and / or

[0603] - comprises a hole 23 located in said housing 9 of said piston 5 .

[0604] The connection holes 13 are arranged as follows:

[0605] - the piston 5 closes when it moves, thereby reducing the internal volume of the bag 2,

[0606] - The piston 5 opens when it moves, thereby increasing the internal volume of the bag 2.

[0607] Note that the depicted embodiment includes cavity 139 .

[0608] The cavity 139 corresponds to the inner volume of the piston 5 .

[0609] The cavity 139 is not closed, but the fluid contained in the reservoir 6 can flow from the reservoir 6 to the cavity 139 and / or from the cavity 139 to the outlet 24 .

[0610] However, most (more than 50%) or even the entire volume of cavity 139 is dead volume, for example, the fluid can flow from reservoir 6 to outlet 24 without interfering with or causing movement of the fluid in cavity 139.

[0611] Also note that when the piston 5 enters its housing 11 , the internal volume of the chamber 139 is greater than the maximum volume of fluid that can be discharged from the outlet 24 .

The outlet 24 is closed by the front face of the stem 27 (forming these chambers 57 of the mixer 25 for connecting the channels 59), which are fed by three channels 59 formed by the side walls of the stem 27 and the triangular hole of the distribution part 25, which are separated from each other and arranged to define these three channels 59. In a variant, there are at least two chambers 57 and at least two channels 59. Each blade is located at the bottom of the part 25 so as to increase the pressure at the outlet 24 and generate a vortex. Therefore, these channels 59 are directed towards the same central direction, so as to generate a vortex. The grooves in the inner wall of the channel 20, which are also extensions of the channels 59, give the fluid a rotational motion for circulation there.

[0636] The channel 59 and the cavities 57 (located in the extension of the channel 59 ) are arranged to generate a vortex at the outlet 24 , including the respective flow coming from the bag 2 .

[0637] The movable wall 3 is a deformable wall.

[0638] The movable wall 3 includes the connecting wall 7. More precisely, there is material continuity between the movable wall 3 and the connecting wall 7. The movable wall 3 and the connecting wall 7 are similar, that is, they are made of the same material.

[0639] For example, the walls 3 and 7 are made of polypropylene.

[0640] The movable wall 3 at least partially delimits the outer bag 2 2 The movable wall 3 forms a dome, that is, the movable wall 3 includes a concave portion relative to the bottom wall 21.

[0643] The bottom wall 21 preferably comprises a planar or substantially planar shape, onto which the movable wall 3 is fixed.

[0644] The movable wall 3 is fixed or welded to the bottom wall 21 , especially fixed or welded to the plane of the bottom wall 21 .

[0645] The bottom wall 21 is a rigid wall, that is, more rigid than the movable wall 3 .

[0646] For example, the movable wall 3 is a thin wall, and for example, the bottom wall 21 is a thicker wall than the movable wall 3 .

[0647] The movable wall 3 is preferably made of PP, through polymer or plastic additives (for example, Vistamaxx TM 6202) in order to reduce its hardness, so that the hardness of the movable wall 3 is less than 80 Shore hardness. Therefore, too much fineness and brittleness of the movable wall 3 are avoided.

[0652] The deformable envelope 56 comprises a pressure-bearing surface 26 arranged to receive the pressure 18 from outside the device 1900 , outside the device 1900 , and perpendicular to the longitudinal direction of the dispensing channel 20 .

[0653] Thus, each time a pressure 18 greater than the threshold force is applied, the piston 5 or a portion of the piston 5 will move into the housing 9 of the piston 5 and the piston or a portion of the piston will begin to be located in the outer bag 2. 2 in the internal volume.

[0654] Thus, the reservoir 6 is arranged to reduce its internal volume, which occurs after the inlet valve 38 is in the open state.

[0655] The reservoir 6, in particular the deformable wall 56 of the reservoir 6, comprises means 31 for fixing the reservoir 6 to the bag 2, in particular to the bottom wall 21, in particular comprising the inner bag 2. 1 part of.

[0660] Thus, flange 45 is arranged to mount and / or secure said edge 31 at a corner of said reservoir 6 within said bag 2 by exerting a mounting pressure (not shown) on said retaining surface 53 of said reservoir 6 .

[0661] The device 1900 may be reassembled from a single material, typically a material from the same family as the polyolefin component.

[0662] Fig. 20 It is an exploded view of the device 1900 , excluding the reservoir 6 .

[0666] In the case of a method of device 100 comprising a reservoir 6 , said movable wall 3 must be mounted to said bottom wall 21 . Thus, said reservoir 6 is clamped between said dispensing head 10 , which is at the level of said flange 45 , and a bag 2 .

[0667] Note that along the translation axis of the housing 9 within the piston 5 , starting from the wall 3 :

[0668] - The inner bag 2 to which the shell 9 extends 1 below the passage for connecting the hole 13 with the valve 28, and / or

[0680] The device 2300 further comprises a cap 74, which is arranged to be positioned and / or fixed on the dispensing head 10. When the cap 74 is fixed to the dispensing head 10, no fluid can flow out through the outlet 24 of the device 2300. The cap 74 is arranged to be airtight when it is pressed against the outlet 24, for the start-up phase of vacuum filling.

[0681] The cap 74 is made of plastic.

[0682] In the device 1900, the movable wall 3 includes the connecting wall 7. The movable wall 3 and the connecting wall 7 have material continuity.

[0683] However, the movable wall 3 is not made of the same material as the connecting wall 7 .

[0684] The movable wall 3 is made of PP, PE or TPO.

[0685] The connecting wall 7 is made of PP, PE or TPO.

[0686] The connecting wall 7 is rigid, ie, more rigid than the movable wall 3 .

[0689] The plate 43 is arranged to be located on the bottom wall 21 of the bag 2 .

[0690] The plate 43 is arranged to be fixed on the bottom wall 21 of the bag 2, more precisely on the upper surface 21 of the bottom wall 21. 1 .

[0691] The upper surface 21 of the bottom wall 21 1 Basically flat.

[0692] The plate 43 is fixed and / or welded to the bottom wall 21 of the bag 2 .

[0693] The volume of the reservoir 6 is situated between the bottom wall 21 of the bag 2 and the deformable envelope 56 .

[0694] The deformable envelope 566 of the reservoir comprises continuous radial corrugations 566 located about the axis B. 2 .

Then the dispensing head 10 is installed on the housing 41 of the bag 2 (especially on the bottom wall 21 including the inner bag 2). 1If the device 230 is not used, the cap 74 is placed on the face of the dispenser head 10, which includes the outlet 24. The plate 43 is then assembled with the bottom wall 21, which has a bottom surface 21 1 superior.

[0701] The plate 43 must be fixed to the bottom wall 21 .

[0702] The assembly method of the device 2300 is performed under vacuum and includes vacuum welding.

[0703] The vacuum assembly process includes the following consecutive steps:

[0704] - positioning at least a portion of the reservoir 6, at least a portion of the bag 2, assembling the dispensing valve 28, the dispensing head 10 and the cap 74 on said portion,

[0705] - filling the future internal volume of the reservoir 6 (and preferably the future internal volume of the bag 2) with the dispensed fluid,

[0706] - closing the reservoir 6 (through the wall 56) and the bag (through the wall 3),

In this variant, the wall 3 is brought into contact with a button or wall of the housing, thereby forming the pressure surface 26. The button is guided by the guiding means of the device, so that the device is pressed against the active surface 3, while the device is guided by a translation movement parallel to the direction of extension of the piston 5.

[0718] Figure 26 to Figure 27 A seventh embodiment of an apparatus 3000 for dispensing fluids is shown. Fig.17 The differences between the devices described in are explained.

[0719] The device 3000 for dispensing the fluid comprises:

[0720] - bag 2, said bag including inner bag 2 1 and outer bag 2 2 , the inner bag 2 1 At least partially located in the outer bag 2 2 inside, the inner bag 2 1 having an internal volume arranged to contain the fluid, the outer bag 2 2 having an internal volume arranged not to contain the fluid, the outer bag 2 2 The internal volume of the dispensing head 10 is at least partially delimited by a movable wall 3 [preferably a wall integrated with the cap 305, which has material continuity, more precisely a thin wall (at least 2 times thinner than the wall thickness of the dispensing head 10)], the movable wall 3 being arranged to reduce the inner bag 2 when a pressure 18 is applied. 1 The internal volume (and the outer bag 2 2 internal volume), is achieved through deformation and / or movement,

[0721] - an outlet 24 arranged to distribute said fluid.

[0722] The inner bag 2 1 The interior volume of is defined at least in part by:

[0723] a piston 5 , which is integral with a connecting wall 7 and serves to at least partially delimit the outer bag 2 2 The internal volume of

[0724] A housing 9 of the piston 5 , which is arranged to accommodate the piston 5 and to guide the piston 5 during its axial movement 11 inside the housing.

[0725] The inner bag 2 1 The internal volume of is the internal volume of the shell 9.

[0726] The device 3000 is arranged to direct the fluid in a circuit comprising a path leading from the reservoir 6 and / or from the head cavity 306 to the inner bag 2 1 inside, not flowing through the outer bag 2 2 The interior (the connecting hole 13 is connected to the outer bag 2 2 The internal volume of the inner bag 2 1 and / or the interior of the piston 5, not shown in the described embodiment).

[0727] The dispensing head cavity 306 is the volume inside the dispensing head 10 , preferably containing the product, and facing the reservoir 6 .

[0728] The dispensing head cavity 306 is arranged not to press against the fluid.

[0729] The dispensing head cavity 306 is located in the bag 2 1 Outside.

[0730] exist Fig.26 In this case, the dispensing head cavity 306 corresponds to the internal volume of the piston 5.

[0735] The device 3000 is arranged to operate in all positions of the dispensing head 10, in particular upwards or downwards relative to the earth's gravity, and the device includes a device for returning the piston 5 or the housing 9 (in contrast to an inverted dispenser device / cartridge, the return device is located outside the cartridge), without the need for the channel.

[0736] The device 3000 further comprises a braking device 15 arranged to prevent the piston 5 from performing the axial movement 11 in the housing 9 when the movable wall 3 is subjected to a pressure force 18 (formerly referred to as external force 18) less than a threshold force.

[0738] - a lug or a projection, located on the outside of the piston 5 and / or inside the housing 9, the lug or the projection being arranged to frictionally

[0739] , or blocked by a surface on the outside of the housing 9 and / or on the inside of the piston 5, and / or - a lug or a projection, located on the outside of the housing 9 and / or on the inside of the wall 303 surrounding the housing 9, which rubs against, or is blocked by a surface on the inside of the wall 303 and / or on the outside of the housing 9. These embodiments are better because they act on the face-to-face surfaces of the seal between the piston 5 and the housing 9, without damaging the seal.

[0740] Therefore, the piston 5 and the housing 9 are arranged so that when the force 18 is applied (which we call the relative movement of the piston 5 relative to the housing; in fact, Fig.26 In the embodiment of the present invention, the housing moves around the piston 5 (through the dispensing head 10) while the piston 5 is stationary), three stages of movement of the piston 5 are allowed in the housing 9:

[0741] 1) a blocking phase, during which the piston 5 does not move beyond the device 15 as long as the force 18 is less than the threshold force, and then moves past the device 15 as soon as the force 18 is greater than the threshold force;

[0742] 2) free movement of the piston 5 within the housing 9, once the piston 5 passes the device 15, which is generally based on the piston 5 moving at least 0.5 mm or even 1 mm in its housing 9, making it possible to provide a push or acceleration for the threshold force (kinetic energy), and

[0743] 3) Compression stage, including the bag 2 1 The increase in pressure described in.

[0744] The cavity 306 generally remains stationary.

[0745] The most important are stages 1 and 3, stage 2 is optional.

[0746] In certain configurations, stage 1 may be restored by the friction of the piston in the housing (dynamic friction being less than static friction).

[0748] The device 3000 comprises a pressure-bearing surface 26 (also referred to as a contact surface 26) arranged to reduce the pressure of the inner bag 2 when the pressure 18 is applied and when passing through the dispensing head 10. 1 (and outer pocket 2 2 )'s internal volume, which is achieved by deformation and movement of the movable wall 3.

[0749] The dispensing head 10 is arranged to move in the direction of the reservoir 6 so that when it moves toward or close to the reservoir 6, the fluid flows out of the dispensing head 10 laterally, that is, it flows out of the outlet 24 from a vertical or inclined outlet direction relative to the moving direction.

[0750] The movable wall 3 has the technical function of a spring or return means, that is, by exerting a force, the piston 5 is returned toward the outside of the housing 9. The dispensing head 10 comprises a return means for the piston or housing, without a metal spring, preferably made of polyolefin, more precisely of polypropylene (PP) (single material or homogeneous).

[0779] The connecting wall 7 comprises a substantially planar shape. In the case of the device 3000 , the connecting wall 7 is rigid, ie more rigid than the deformable wall 3 of the bag 2 .

[0780] The movable wall 3 is located between the bottom wall 21 and the connecting wall 7 .

[0781] The connecting wall 7 has the same rigidity as the bottom wall 21 .

[0782] The connecting wall 7 is fixed to the movable wall 3 .

[0783] The movable wall 3 is fixed to the bottom wall 21 .

[0784] The deformable wall 3 is flexible.

[0785] The movable wall 3 is generally made of PP which is thinner than the remaining parts.

[0786] The piston 5 is fixed to the connecting wall 7 by interlocking, by welding and / or casting, or preferably the piston 5 and the connecting wall are the same part.

[0787] The piston 5 is integrated with the flat portion of the connecting wall 7 .

[0788] The connecting wall 7 is made of PP.

[0789] The piston 5 is made of the same material as the connecting wall 7. In the device 3000, the piston 5 and the connecting wall 7 are formed in one piece.

[0790] Therefore, the piston 5 is located between the flat portion of the connecting wall 7 and the housing 9 of the piston 5 .

[0791] The housing 9 of the piston 5 is located between the piston 5 and the dispensing channel 20. The channel 20 is optional, in particular if a flat or sufficiently small dispensing valve is used, for example of the "studded" type.

[0792] The piston 5 is hollow and cylindrical.

[0793] The outer diameter of the piston 5 comprises an increase in diameter at the end of the piston 5 of the housing 9 facing the piston 5. This arrangement makes it possible to have a sealing linear annular contact during the compression phase, that is to say when the dispensing head 10 is driven by the translational movement, thereby reducing the volume of the bag 2. This can, among other things, increase the sealing performance of the device 3000. A low rotational movement, for example of the ball joint type, can optionally be complementary to the translational movement.

[0794] The device 3000 further comprises a feed orifice 8 for connecting the interior of the piston 5 and / or the reservoir 6 with the inner bag 2 1 The internal volume does not flow through the outer bag 2 2 .

[0795] The device 3000 comprises the reservoir 6. The reservoir 6 is not connected to the outer bag 2 through the feed orifice 8 or any other orifice. 2 The reservoir 6 comprises an internal volume arranged to contain the fluid.

[0796] The apparatus 3000 is arranged to direct the fluid along the above-mentioned path:

[0797] - In the inner pocket 2 1 Each time the volume of the dispensing head 10 increases, that is, each time the piston comes out of the outside of the housing 9, directly from the reservoir 6 and / or from the dispensing head cavity 306 to the inner bag 2 1 inside, does not flow through the outer bag 2 2 inside, then

[0798] - Each time the pressure 18 on the movable wall 3 is greater than the threshold force, and / or each time the inner bag 2 1When the internal volume is reduced (and the outer bag 2 2 When the internal volume of the inner bag 2 is reduced), for example, each time the piston 5 moves toward the inner side of the housing 9, the flow through the inner bag 2 1 The inner side of the bag 2 is directed toward the hole 22, then flows through the channel 20, and then flows through the outlet 24. The piston 5 moves in the housing 9, so that the bag 2 1 The product is compressed within a volume.

[0799] An inlet valve 38 is located in said orifice 8 .

[0800] The valve 38 generally comprises a membrane pressing the piston 5 against the edge of the housing 9. The valve 38 is not mechanically connected to the dispenser head 10. The valve is mounted laterally, not within the axis of the dispenser head.

[0801] When the valve 38 is in an open state (the open state is particularly when the bag 2 1 The internal volume increase is achieved during the period of allowing the fluid contained in the reservoir 6 and / or inside the piston to move toward the bag 2 1 flow, and the valve is in a closed state (the closed state is especially the bag 2 1 is achieved when the internal volume is reduced) and no outflow is allowed.

[0802] After (sufficient) pressure on the movable wall 3, the feed valve 38 is closed, so that it forms the inner bag 2 1 of the feed valve.

[0803] The valve 38 is arranged as follows:

[0804] - The piston 5 moves to close, thereby reducing the size of the bag 2 1 The internal volume of

[0805] - The piston 5 opens when it moves, thereby increasing the size of the bag 2 1 internal volume.

[0806] The device 3000 further comprises a ring 74 which is arranged to be positioned and / or adapted on the dispensing head 10 .

[0807] The wall 7 comprises or is integrated with a device 304 (comprising the wall 302) which is arranged to guide the movement of the dispensing head 10 and is located inside the dispensing head 10. This allows the height of the device 3000 to be reduced.

[0808] like Fig. 27 Said flexible reservoir may be clamped by a rigid ring, integrated with said reservoir, or not. One edge of the wall 7 may accommodate a ring 74 .

[0809] Bag 2:

[0810] - directly below a pressure-bearing surface 26 arranged to receive said pressure 18 from outside said device, or

[0811] - directly below an assembly comprising a pressure-bearing surface 26 arranged to receive said pressure 18 from outside said device, and a channel comprising a valve.

[0812] In the embodiment described, the device according to the invention comprises return means 307 , which are non-metallic, arranged to stop the piston 5 and / or to move it away from its housing 9 .

[0813] The area S2 of the inner cross section of the housing 9 is divided into at least two parts relative to the area S1 of the pressure-bearing surface 26 arranged to receive the pressure 18 from the outside of the device.

[0814] For the nebulizer, spray between 50 μl and 100 μl.

[0815] The internal volume (V1) of the piston 5 is greater than 40 microliters.

[0816] The sum of the internal volume (V1) of the piston 5 and the internal volume (V2) of the housing 9 is greater than 80 microliters.

[0817] A crimp ring 180 may crimp the reservoir onto the bottom wall.

[0818] Note that the embodiment includes the cavity 306 .

[0819] The cavity 306 corresponds to the inner volume of the piston 5 .

[0820] The cavity 306 is not closed, but the fluid contained in the reservoir 6 can flow from the reservoir 6 to the cavity 306 and / or from the cavity 306 to the outlet 24 .

[0821] However, it is worth noting that most of the volume of the cavity 306 (more than 50%) or even preferably all of its volume is not dead volume, that is, the fluid circulating from the reservoir 6 to the outlet 24 interferes with and generates the movement of the fluid in the cavity 306.

[0822] It is also worth noting that when the piston 5 enters its housing 11 , the internal volume of the cavity 306 is greater than the maximum volume of the fluid discharged from the outlet 24 .

[0823] The movable wall 3 has the technical function of a spring or a return device, and moves the piston 5 toward the outside of the housing 9 by applying a force.

[0824] exist Fig.26 In FIG. 1 , it can be seen that the housing 9 is at least partially formed by at least part of the movable wall 3 .

[0825] The housing 9 is in direct contact with the wall forming the pressure-bearing surface 26 .

[0826] The housing 9 is formed within the same portion of the pressure-bearing surface 26 and / or the housing 9 is at least partially formed by at least a portion of the pressure-bearing surface 26 .

[0827] Preferably, the housing 80 is formed in two stages:

[0828] - firstly, the channel 20 is formed by casting, leaving an opening for the mold shaft used for the casting, the opening being generally located in the extension of the channel 20 opposite the outlet 24, and then - secondly, at least part of the opening is closed (by injecting a flexible or rigid material), the valve 28 being preferably inserted into the housing 80 through the opening.

[0829] Figure 28 to Figure 29 An eighth embodiment of an apparatus 4000 for dispensing fluids is shown. Fig. 27 The differences between the device 3000 described above are explained.

[0830] The apparatus 4000 for dispensing a fluid comprises:

[0831] -Exit 24,

[0832] a bag 2 having an internal volume for containing a fluid, said internal volume being at least partially delimited by a movable wall 4,

[0833] - a reservoir 6 arranged to contain said fluid,

[0834] - Bag cap 40.

[0835] The bag cap 40 comprises an inlet valve 38, which allows fluid to flow from the reservoir 6 to the internal volume of the bag 2 when the inlet valve is in an open state, and does not allow inflow when the inlet valve is in a closed state; and / or comprises a dispensing valve 28, which allows fluid to flow from the internal volume of the bag 2 to the outlet 24 when the dispensing valve is in an open state, and does not allow inflow when the dispensing valve is in a closed state. The device 4000 comprises the inlet valve 38 and the dispensing valve 28.

[0836] The inlet valve 38 of the device 4000 allows fluid to flow from the reservoir 6 to the internal volume of the bag 2 when in an open state, and does not allow inflow when in a closed state. The inlet valve 38 is located in the bag cap 40 so that in its open state, the inlet orifice 8 is opened, and in its closed state, the inlet orifice 8 is closed.

[0837] In the case shown, the bag cap 40 comprises the inlet valve 38 and the dispensing valve 28 .

[0838] The inlet valve 38 is integrated with the dispensing valve 28 and is a single piece. The dispensing valve 38 is located on the inlet orifice 8 and prevents the fluid from flowing in the dispensing channel 20 located in the bag cap 40 toward the outlet 2 .

[0839] The dispensing valve 38 and the inlet valve 28 are located in a housing 130 , which is located in the bag cap 40 .

[0840] The housing 130 of the bag cap 40 is arranged to accommodate the feed valve 38 and the dispensing valve 28. The housing 130 is connected to the dispensing channel 20.

[0841] The device 4000 further includes:

[0842] - cavity 122,

[0843] A reservoir aperture 124 for forming a junction between said reservoir 6 and said cavity 122 .

[0844] The cap 40 is arranged to be installed by insertion into the cavity 122 of the device 4000 so as to be installed by:

[0845] - extends from said reservoir 6 to said outlet 24, at least partially passing through said bag 2 and at the same time through said movable wall 4, or

[0846] - at least partially extending along the bag 2 (at Fig.28 or Fig.29 In the special case of the bag, it is worth noting that the bag cap 40 is arranged to be installed by insertion into the cavity 122 of the device 4000, thereby extending along the bag 2 over its entire length).

[0847] In the case of the device 4000 , the bag cap 40 is mounted at least partially by extending along the bag 2 .

[0848] The device 4000 comprises an inlet opening 120 arranged for inserting the bag cap 40 into the device from the outside of the device 4000 and opening in the cavity 122 .

[0849] The interior volume of the bag 2 includes at least a portion (eg, partially or entirely) that is outside the cavity 122 .

[0850] The cavity 122 is entirely located outside the reservoir 6 .

[0851] The bag cap 40 comprises an internal volume, called top reservoir 126 , which is arranged to lead to the reservoir hole 124 on one side and to a feed orifice 8 on the other side for connecting the top reservoir 126 with the internal volume of the bag 2 .

[0852] The cavity 122 comprises an internal volume, different from the internal volume of the bag 2 .

[0853] The top reservoir 126 is located within the cavity 122. The top reservoir 126 includes a rounded end that faces the side of the reservoir 6.

[0854] The movable wall 4 is fixed to at least one outer wall of (and delimits) the cavity 122 . Thus, part of the internal volume of the bag 2 is located inside the cavity 122 , except for the internal volume limitation of the deformable wall 4 .

[0855] The top reservoir 126 has an internal volume of at least 1 cubic centimeter, or even at least 3 cubic centimeters, or even at least 5 cubic centimeters, and / or has air or fluid to be dispensed.

[0856] The bag cap 40 is installed in the cavity 122 so that the wall of the bag cap forms a first sealing joint 148 at the threaded connection end, the wall is inserted into the reservoir hole 124 and at least partially defines the top reservoir 126, and the first sealing joint is located between the internal volume of the bag 2 and the reservoir 6.

[0857] The first sealing joint 148 is arranged so as to seal at the threaded end. All other joints in the device are as described. The seal 149A comprises a flexible material in axial compression. The seal 149B is a skirt having radial elements that are larger than the axial elements.

[0858] The first sealing joint 148 takes the form of a collar and is situated in a wall delimiting at least a portion of said reservoir 6. The first sealing joint 148 is situated in particular on a portion of said reservoir 6.

[0859] The seal of the first sealing joint 148 is produced by radial pressure (e.g. having larger elements than in other directions) in particular by mounting and / or threading one end of the top cover 126 of the dispenser head with one end of the reservoir 6, the seal taking the form of a collar 148.

[0860] When the bag cap 40 is installed in the cavity 122, the top reservoir 126 does not extend over the entire volume of the cavity 122.

[0861] To fill the device, the bag cap is removed, the reservoir and then at least part of the cavity 122 and / or the bag 2 is filled with the product to be dispensed, then one end of the cap 40 is inserted into the cavity 122, the product will then return to the cap 40 and / or the bag 2, and the air is exhausted through the hole 120. Air collected in the top reservoir can be exhausted through the vent 146. The cap is tightly threaded by using seals 149A and / or 149B.

[0862] The pocket cap 40 includes ventilation holes 146 .

[0863] The vents 146 are generally holes that allow air contained in the cavity 122 and / or the reservoir 6 to escape when the bag cap 40 is inserted into the cavity 122. The vents 146 can avoid the effects of air overpressure and prevent air from being trapped in the device.

[0864] Therefore, when the bag cap 40 is inserted into the cavity 122, the air contained in the cavity 122 is discharged through the vent holes 146. At the threaded end of the cap 40, the vent holes 146 are blocked by the inner wall of the cavity 122.

[0865] The dispensing head cap 40 comprises a second portion 128 separate from the top reservoir 126 and arranged to direct the fluid from the internal volume of the bag 2 towards the outlet 24 .

[0866] The dispensing channel 20 is located in the second portion 128. The dispensing channel is located in the housing 130 of the cap 40.

[0867] The second part 128 also comprises the dispensing valve 28, which is located in the dispensing channel 20 and allows fluid to flow from the internal volume of the bag 2 to the outlet 24 when the dispensing valve is in an open state, and does not allow inflow when the dispensing valve is in a closed state.

[0868] The outlet 24 is located on the second portion 128 of the bag cap 40 , and more precisely, on the outer wall of the second portion 128 .

[0869] Thus, the device 4000 is arranged to direct the fluid along a circuit comprising:

[0870] - a first path 141 from the reservoir 6 through the reservoir aperture 124 to the top reservoir 126, and then

[0871] - a second path 142 leading from the top reservoir 126 through the feed orifice 8 to the internal volume of the bag 2, and then

[0872] A third path 143 for connecting the internal volume of the bag 2 with the outlet 24 through the second portion 128 of the bag cap 40 .

[0873] The device 4000 is arranged to guide the fluid along a first path and a second path after each end of pressure 18 on the movable wall 4 of the bag and / or after each increase in the internal volume of the bag 2 .

[0874] The device 4000 is arranged to guide the fluid along a third path, after each end of pressure 18 on the movable wall of the bag 2 and / or increase in the internal volume of the bag 2 , the feed orifice 8 being closed by the feed valve 38 .

[0875] The pressure is usually provided by the user pressing with his finger (usually on the wall 4), which may be done by means of a lever or a button.

[0876] The inlet valve 38 is opened by any pressure on the movable wall 4 .

[0877] Therefore, the inlet valve 38 is opened, allowing the fluid to flow along the second path.

[0878] For example, when the user removes his finger from the movable wall 4, the dispensing valve 28 opens after each depression.

[0879] Therefore, the inlet valve 38 is opened, allowing the fluid to flow along the third path.

[0880] The cap 40 comprises fixing means 132 arranged to fit the cap 40 to the wall delimiting the cavity 122 by means of a screw connection.

[0881] The fixing device 132 comprises an anti-unlocking system 132 of the bag cap 40 to the cavity 122, and the anti-unlocking system is arranged to prevent the bag cap 40 from being loosened. For example, the anti-unlocking system 132 is a system 132 with helical teeth, allowing the cap to rotate in the direction of screwing it, but not allowing rotation in other directions from loosening it.

[0882] These bevel teeth are arranged over the entire circumference of the circular end of the reservoir head 126 facing the reservoir 6. In a variant (not shown) of the device 4000, these bevel teeth are inserted into grooves, which are carried out during tightening, and after tightening, they are blocked in the grooves, thus preventing the top reservoir 126 from loosening in the cavity 122.

[0883] The reservoir 6 , the chamber 122 and the bag 2 , with the exception of the movable wall 4 of the bag 2 , are integrated together so as to form a single piece.

[0884] The movable wall 4 of the bag 2 is assembled by welding to the single piece formed by the cavity 122 and the reservoir 6 .

[0885] The movable wall 4 of the bag is flexible, ie more flexible than the rest of the bag 2 .

[0886] The movable wall 4 is generally made of PP, PE or TPO, and is thinner than the thickness of the cavity 122 or the thickness of the reservoir 6 .

[0887] The movable wall 4 of the bag 2 is convex, that is, it comprises a curved portion. For example, the bag is concave (in the direction from the cavity 122 towards the bag 2). In variants not shown, the bag 2, and in particular the movable wall 4, can have different shapes, for example, oval, rectangular, square, spherical, etc.

[0888] The reservoir 6 and the chamber 122 are formed as a single piece.

[0889] The reservoir 6 and the cavity 122 are produced by injection polymer and / or blowing of PP, PE or TPO. The reservoir 6 is a cylindrical box provided with a piston, preferably made of the same material as the walls of the reservoir, preferably made of polyolefin, preferably comprising a single annular belt arranged to press against the inner wall of the reservoir.

[0890] The reservoir 6 extends in a longitudinal direction centered about a first axis of elongation A.

[0891] The bag 2 extends in a longitudinal direction centered on the second axis of elongation, and / or the bag cap 40, preferably the top reservoir 126, may extend in a longitudinal direction centered on the third axis of elongation C.

[0892] The first elongation axis A is offset relative to the second axis and / or the third axis C. In this way, the reservoir 6 and the bag cap 40, in particular the top reservoir 126, are not on the same axis and are offset.

[0893] The first elongation axis A and / or the second elongation axis and / or the third elongation axis C are parallel to each other.

[0894] The cap 40 extends along an elongation direction 136, coinciding with the longitudinal direction of the cap 40. The cap 40 is arranged to be installed by insertion into the cavity 122, with the insertion direction parallel to its elongation direction 136, the inlet opening 120 and the reservoir aperture 124 being aligned in the elongation direction 136.

[0895] The plane of the inlet opening 120 and the plane of the reservoir hole 124 are parallel to each other and perpendicular to the extension direction 136 of the bag cap 40 .

[0896] The bag cap 40 is inserted into the cavity 122 through the inlet 120. Then, the bag cap 40 is screwed onto the reservoir 6 through the anti-unlocking system 132.

[0897] Note that in a variant of the device 4000, the inlet valve is not carried by the cap 40, but directly connects the reservoir 6 with the bag 2, the device 4000 being then arranged to direct the fluid according to a circuit:

[0898] - does not include the first path 141, flowing from the reservoir 6 to the top reservoir 126 through the reservoir hole 124, then if the valve is on the bottom wall, there is no first path and no flow through the top reservoir

[0899] - does not include a second path 142, flowing from the top reservoir 126 through the feed orifice 8 to the internal volume of the bag 2, then

[0900] - It only comprises a path from the reservoir 6 to the bag 2 through the portion 128 of the bag cap 40 , and then the path 143 connects the internal volume of the bag 2 with the outlet 24 .

[0901] Fig.30 A ninth embodiment of an apparatus 5000 for dispensing fluids is shown. Figure 28 to Figure 29 The differences in the device 4000 will be described.

[0902] More specifically, Fig.30 Shown Figure 28 to Figure 29 A variation of the device 4000 described in .

[0903] In the device 5000, the reservoir 6, the chamber 122 and the bag 2 are integrated together so as to form a single piece.

[0904] The reservoir 6, the cavity 122 and the bag 2 are manufactured by injecting PP, PE or TPO polymers, or by 3D printing (for 3D printing, the rigid part can be made of rigid TPU and the flexible (deformable) part can be made of soft TPU).

[0905] In the case of the device 5000 , the bag cap 40 also includes the top reservoir 126 , which is inserted into the cavity 122 .

[0906] In the apparatus 5000 , when the cap 40 is installed in the cavity 122 , the top reservoir 126 extends over the entire length of the cavity 122 , and the cavity is arranged to accommodate the top reservoir 126 .

[0907] The cap 40 further includes the vent 146 , which is arranged to discharge the air contained in the cavity 122 when the cap 40 is inserted into the cavity 122 .

[0908] The cavity 122 is separate from the inner volume of the bag 2 .

[0909] When the bag cap 40 is inserted into the cavity, the device 5000 includes a first sealing joint 148 that forms a first sealing joint between the volume of the bag 2 and the reservoir 6 when the bag cap 40 is fixed in the cavity 122.

[0910] A first sealing joint 148 is formed when the wall of the cavity 122 exerts a transverse or radial force at the level of the wall of the top reservoir 126 (positioned near the reservoir 6 and inserted into the cavity 122 ).

[0911] However, the sealed joint 148 is not necessary as there may be a slight gap in the level of the element 124 and a slight stress relief on the element 150 .

[0912] The bag cap 40 is installed in the cavity 122 so that the wall 40 of the bag cap forms a second sealing joint 150 at the threaded connection end, the wall of the bag cap is inserted into the reservoir opening 124 and at least partially defines the top reservoir 126, and the second sealing joint is located between the internal volume of the bag 2 and the top reservoir 126.

[0913] The second sealing joint 150 is arranged so that it seals on the product at the threaded end to be at least 50% tight.

[0914] In the device 5000 , the vent 146 is arranged to vent air contained in the cavity 122 or the top reservoir 126 from the device 5000 when the bag cap 40 is installed or arranged in the cavity 122 .

[0915] In a variant (not shown) of the device 6000, the reservoir 6 may include at least one flexible wall arranged to extend in the reservoir 6 according to Fig.10 , Fig.11 and Fig.12 The same principles of the device 700 are described as being inserted into the top reservoir 126 when emptying it of fluid.

[0916] There is a seal between the cap 40 and the bottom wall 21 .

[0917] Fig.31 and Fig.32 A tenth embodiment of an apparatus 6000 for dispensing fluids will be described. Figure 28 to Figure 29 The differences between the device 4000 are explained.

[0918] In the device 6000, the reservoir 6, the chamber 122 and the bag 2 are integrated together so as to form a single piece.

[0919] The reservoir 6, the cavity 122 and the bag 2 are produced by 3D printing.

[0920] The cavity 122 is provided with deformable walls forming portions 611 , 662 and 663 of the reservoir 6 and arranged to increase the volume of the reservoir 6 laterally.

[0921] In the device 6000 , the reservoir 6 is divided into portions 661 , 662 and 663 . Thus, the embodiment comprises a plurality of feed orifices 124 , one per portion of the reservoir 6 , for connecting the reservoir 6 with the chamber 122 .

[0922] The device 6000 comprises two bags 211 and 212 which are diametrically opposed to each other and are located on the outer wall of the chamber 122 (or the outer wall of the reservoir 6).

[0923] Thus, the device 6000 comprises two feed orifices 8 , each connected to the cavity 122 inside the reservoir 6 or the bag 2 .

[0924] The deformed walls of the portions 661, 662 and 663 of the reservoir 6 are different from the bags 211 and 212. The deformed walls 662 and 663 are at least partially located between the bags 211 and 212.

[0925] The two bags 211 and 212 are identical, but in a variant (not illustrated) of the device 600, the two bags 211 and 212 may have different shapes and therefore different internal volumes. It is also conceivable that the reservoir 6 is arranged to contain two different fluids and that the two bags 211 and 212 are arranged to each contain a specific fluid.

[0926] The bag cap 40 includes two feed valves 38, each of which allows fluid to flow from the reservoir 6 and / or from the cavity 122 to the internal volume of the bag 211 or 212 respectively when it is in an open state, and does not allow inflow when it is in a closed state.

[0927] The device 6000 also comprises the dispensing valve 28 which is separate from the two feed valves 38 and which, when in an open state, allows fluid to flow from the internal volume of the bag 2 to the outlet 24 and, when in a closed state, does not allow inflow.

[0928] Therefore, before reaching the dispensing valve 28, the fluid flows from the reservoir 126 and / or from the chamber 122 to the bag 2 (211 or 212), and from the bag 2 to the channel 20 of the bag cap 40. The dispensing valve 28 is located in the dispensing channel 20.

[0929] The first axis of elongation A is not eccentric with respect to the third axis C. In this way, the reservoir 6 and the cap 40 are located on the same axis, they are coaxial.

[0930] The first axis of elongation A and / or the second axis of elongation and / or the third axis of elongation C are parallel to each other.

[0931] exist Fig.32 In the particular case of , it is worth noting that the bag cap 40 is arranged to be installed by insertion into the cavity 122 of the device 4000, and thus is installed by only partially extending along the bag 2.

[0932] Fig.33 An eleventh embodiment of an apparatus 7000 for dispensing fluids is shown. Figure 31 to Figure 32 The differences between the device 6000 are explained.

[0933] The device 7000 includes the bag cap 40 , the dispensing channel 20 , the feed valve 38 and the dispensing valve 28 .

[0934] The interior volume of the bag 2 is entirely located in the cavity 122 .

[0935] The cavity 122 is entirely located outside the reservoir 6 .

[0936] In particular, the bag 2 and the movable wall 4 of the bag are located inside the internal volume of the cavity 122 .

[0937] In the device 7000 , the dispensing valve 28 is located in the dispensing channel 20 of the bag cap 40 .

[0938] The device 7000 is arranged to guide the fluid from the reservoir 6 to the internal volume of the bag 2 through the reservoir hole 124, and to guide the fluid from the internal volume of the bag 2 to the distribution channel 20 through the distribution orifice 8, and the distribution orifice is used to connect the internal volume of the bag 2 with the distribution channel 20.

[0939] The movable wall 2 of the bag is convex, that is, it comprises a curved portion. For example, the bag is concave, and the concavity is on the inside of the bag.

[0940] The bag cap 40 includes a portion 140 which is different from Figure 28 to Figure 29 In fact, in the case of the device 8000, the chamber 140 is not arranged to lead on one side to the reservoir hole 124 and on the other side to the feed orifice 8 for connecting the top reservoir 126 with the internal volume of the bag 2. The dispensed fluid flows directly from the reservoir 6 to the internal volume of the bag 2, either through the reservoir hole 124 or the feed orifice 8 (combining these two orifices).

[0941] The bag 2 comprises a threaded collar. The portion 140 of the bag cap 40 is inserted into the skirt of the cavity, thereby defining a first sealing junction 148 between the internal volume of the bag 2 and the reservoir 6 .

[0942] The cap 40 is arranged to slide into the bottom wall, which is at the level of the junction 148 .

[0943] The first sealing joint 148 is arranged so that it seals against the product at the threaded end.

[0944] The device 7000 comprises a pressure-bearing surface 26, located on the bag cap 40, also referred to as the contact surface 26, arranged to reduce the internal volume of the bag 2 when the pressure 18 is applied and through the bag cap 40, by deformation and movement of the movable wall 4. When pressed against the pressure-bearing surface 26, the top reservoir slides in the skirt (the bag is crushed). In a preferred embodiment, the portion 140 comprises an insert 145 of the reservoir on the side, in which case the internal volume of the portion 140 preferably contains a gas, such as air.

[0945] The internal volume of the portion 140 extends from the reservoir 6 or from the cap 145 to the dispensing valve. The volume of the portion 140 may be at least 1 cubic centimeter, or even at least 3 cubic centimeters, or even at least 5 cubic centimeters, and it may contain a gas and / or liquid to be dispensed.

[0946] The cap 40 is arranged to be slid into the ring 159 while being guided by the ring 159 .

[0947] The movable wall 4 of the bag comprises a first collar 158 arranged to be assembled (mounted or screwed or clamped) inside the dispensing head cap 40, in particular at the level of the dispensing head of the bag cap 40. The collar 158 of the cavity 122 comprises a wall thicker than the wall delimiting the movable wall 4 of the bag 2. The upper end of the collar 158 of the bag 2 forms the inlet 120.

[0948] Fig.34 A twelfth embodiment of an apparatus 8000 for dispensing fluids is shown. Fig.33 The differences between the device 7000 are explained.

[0949] In the device 8000 , the cavity 122 coincides with the bag 2 . Therefore, the internal volume of the bag 2 is equal to the internal volume of the cavity 122 .

[0950] The device 8000 comprises a bag housing 160 which is at least partially located in the bag 2 in which the inlet valve 38 and the dispensing valve 28 are located. The housing 160 of the bag 2 is arranged to accommodate the dispensing valve 38 and the inlet valve 28.

[0951] The distribution valve 28 and the inlet valve 38 are formed as a single piece.

[0952] The device 8000 is arranged to guide the fluid from the reservoir 6 to the internal volume of the bag 2, in particular the internal volume formed by the movable wall 4 of the bag 2, and through the reservoir hole 124 or the feed orifice 8 (combination of these two orifices), and through the dispensing orifice 8 to guide the fluid from the internal volume of the bag 2 to the dispensing channel 20.

[0953] The movable wall 4 of the bag 2 is convex, ie it comprises a curved portion. For example, the bag 2 is concave.

[0954] The bag cap 40 has a T-shaped piece, the T-shaped piece has an upper portion 162, that is, the top 162 of the T-shaped piece, and a lower portion 140. The portion 140 can be arranged to contain a fluid or not. The fluid can be air, vacuum or fluid distributed by the device 8000.

[0955] In the case of the device 8000, the bag cap 40 is inserted into the cavity 122 (the bag 2) by screwing. Therefore, the cavity 122 and more particularly the movable wall 4 of the bag comprises a first collar 158 arranged to be assembled (mounted or screwed or clamped) in the dispensing head cap 40, in particular at the top of the bag cap 40. The collar 158 of the cavity 122 comprises a wall that is thicker than the wall delimiting the movable wall 4 of the bag 2. The inlet opening 120 is formed at the upper end of the collar 158 of the bag 2.

[0956] The portion 140 of the cap 40 is different from Figure 28 to Figure 29 The portion 140 is a cylinder centered on the axis R. The portion 140 of the bag cap 40 is arranged to be inserted into the cavity 122, in particular into the internal volume of the bag 2, so that the internal volume of the movable wall 4 and the portion 140 are located on a coaxial axis, namely on the axis R. In this way, the internal volume of the movable wall 4 and the portion 140 are coaxial.

[0957] The bag 2 comprises a second collar. The portion 140 of the bag cap 40 is inserted into the second collar of the cavity, thereby defining a first sealing junction 148 between the internal volume of the bag 2 and the reservoir 6 .

[0958] The first sealing joint 148 is arranged so that it seals against the product at the threaded end at least 50% tight.
