    FR 3 065 890 - A1 (54) MODULE FOR DISPENSING FLUID PRODUCT.
    (57) Fluid product distribution module (M) intended to be integrated into a fluid product distribution head mounted on a fluid product reservoir, the fluid product distribution module (M) comprising a fluid product inlet (13 ), a dispensing orifice (50) and a fluid product flow path (Cp) between the fluid product inlet (13) and the dispensing orifice (50), the dispensing module (M) comprising in addition to a valve (3, 20) selectively cutting said fluid product flow path (Cp), said valve (3, 20) opening under a determined pressure of the fluid product in the fluid product flow path (Cp) ) upstream of the valve (3, 20), characterized in that it further comprises a vent path (Ca) of the fluid reservoir.

    The present invention relates to a fluid product distribution module intended to be integrated into a fluid product distribution head mounted on a fluid product tank. The fluid dispensing module includes a fluid inlet, a dispensing orifice and a fluid flow path which extends between the fluid inlet and the dispensing orifice. The distribution module also includes a valve selectively cutting said fluid product flow path: this valve opening under a determined pressure of the fluid product in the fluid product flow path upstream of the valve. The preferred fields of application of the present invention are those of perfumery, cosmetics or even pharmacy.
    In the prior art, document EP0117898 is known, for example, which describes a sprayer incorporating a fluid product distribution module comprising a fluid product inlet, a valve sensitive to the pressure of the fluid product and a nozzle capable of dispensing the fluid product. in spray form. The fluid under pressure at the inlet of the dispensing module moves a movable member of the valve so that the fluid can flow in the module to the nozzle where it is sprayed.
    The document US4273290 describes another fluid product distribution module integrated in a distribution head. More specifically, this distribution module is in the form of a nozzle comprising a chamber and swirl channels, as well as a valve in the form of a disc biased by a spring. The pressurized fluid pushes the disc against the spring, so that the fluid can flow inside the nozzle to reach the channels and the swirl chamber before being sprayed out through an orifice of distribution.
    Document WO94 / 27732 is also known, which describes a module for dispensing a fluid product in the form of a nozzle in which is placed a core of flexible material which acts as a valve. The fluid under pressure deforms the flexible core so that the fluid can flow to the dispensing orifice.
    Thus, in these documents of the prior art, the fluid dispenser module defines a fluid product flow path which extends from an inlet of the dispenser module to a dispensing orifice. The valve is arranged on this fluid dispensing path so that it can be cut or opened selectively under the action of the fluid under pressure.
    The present invention aims to provide additional functionality to this type of fluid dispensing module. To do this, the present invention provides that the fluid dispenser module further comprises a vent path for the fluid reservoir, so that outside air can enter the reservoir through the dispenser module. fluid product as fluid is removed from the reservoir and passes through the fluid dispenser module. In other words, the fluid dispenser module of the present invention makes it possible to manage the cross-flow of the fluid product and the outside air in order to ensure that the reservoir is always kept at atmospheric pressure.
    Advantageously, the valve selectively cuts said vent path. Thus, the fluid valve also acts as an air or vent valve by selectively opening and closing the vent path.
    According to a practical and advantageous embodiment, the valve comprises a movable member which simultaneously closes a first lateral opening of the fluid product flow path and a second lateral opening of the vent path in a rest position, under the stress of 'a spring, and which releases these two lateral openings in an open position under the pressure of the fluid upstream of the movable member against the spring. Thus, the movement of the movable member makes it possible to hide and unmask the first lateral opening and the second lateral opening so as to cut or simultaneously open the fluid product flow path and the venting path.
    Advantageously, the movable member comprises two piston lips which slide in leaktight manner in a sliding barrel which forms the two lateral openings, the two piston lips closing the two lateral openings in the rest position. Preferably, the movable member comes into tight abutment in the rest position under the action of the spring against a radial shoulder of the fluid product flow path. This guarantees a double seal at the fluid product flow path.
    According to an advantageous embodiment, the fluid product distribution module comprises:
    - a mounting body intended to be fixedly received in a mounting housing for the dispensing head,
    - an insert piece fixedly received in the mounting body, the insert piece forming a sliding barrel,
    - a movable member mounted for leaktight sliding in the sliding barrel,
    - a spring which acts between the insert and the movable member to urge the movable member in the rest position.
    The insert with the spring and the movable member can be inserted axially in the mounting body so as to constitute the fluid dispensing module, which is then fixedly received in a mounting housing for the dispensing head.
    Advantageously, the sliding barrel forms a first lateral opening of the fluid product flow path which is hidden in the rest position by the movable member and released by the movable member, advantageously only after a sealed precompression stroke. Preferably, the first lateral opening is connected downstream to a first groove formed by the insert piece, this first groove communicating downstream with the dispensing orifice, which is advantageously formed by a nozzle mounted on the insert piece . Thus, the fluid dispenser module can be used as an outlet valve of a pump or a valve. It can even serve as a precompression valve, which opens only from a determined threshold of fluid pressure.
    On the other hand, the sliding barrel can form a second lateral opening of the venting path which is hidden in the rest position by the movable member. Advantageously, the sliding barrel forms a third lateral opening of the venting path which communicates with the second lateral opening, when it is released by the movable member, this third lateral opening connecting to a second groove formed by the part d 'insert, this second groove opening onto the outside of the fluid dispenser module.
    The present invention also defines a fluid dispenser head comprising a mounting housing in which is received a fluid dispenser module as defined above.
    The present invention further defines a fluid dispenser comprising a fluid reservoir and a fluid dispensing head incorporating a fluid dispensing module as defined above, the fluid dispensing head being mounted on the fluid reservoir.
    According to one embodiment, the distributor can include:
    - An air flush, such as a flexible bulb, capable of undergoing phases of crushing and elastic relaxation, the air flush being connected to the fluid product inlet of the fluid product distribution module to supply a flow of pressurized air through the fluid product flow path to the dispensing orifice during the elastic crushing phases, and
    - a fluid product conduit also connecting to the fluid product inlet of the fluid product distribution module, the fluid product in the conduit being sucked in by the pressurized air flow by Venturi effect, so as to distribute a mixture air and fluid through the dispensing orifice.
    Alternatively, the fluid dispenser head can also define a pump chamber and an actuating wall on which the user can press to pressurize the fluid product in the chamber so as to discharge it through the module. distribution of fluid of the invention.
    The spirit of the invention lies in improving a conventional fluid dispenser module with fluid valve by adding an additional functionality to manage the venting of the fluid reservoir. An interesting aspect of the invention is that a single valve makes it possible to open and close, advantageously simultaneously, both the fluid product flow path and the venting path.
    The invention will now be described in more detail with reference to the accompanying drawings, giving by way of nonlimiting examples, two embodiments of the invention.

    FIGS. 9a to 9e are views in vertical cross section through a fluid product distribution module according to a second embodiment, during different phases.
    Reference will first be made to FIG. 1 to describe in general a fluid dispenser integrating a fluid dispenser module M according to the invention.
    The fluid dispenser comprises two separate entities, namely a fluid reservoir R and a fluid dispensing head T.
    The fluid reservoir R can be made with any suitable material, such as glass, plastic, metal, etc. It can have any shape, but includes an opening in the form of an R1 neck. The reservoir R contains a fluid product which can be a perfume, a lotion, a cream, a pharmaceutical solution, etc. The reservoir R and its contents are not critical to the present invention.
    The fluid dispensing head T is fixedly and sealingly mounted on the neck R1 of the fluid reservoir R. The head T comprises a head body T1 which can be produced by injection / molding of plastic material. This head body T1 comprises a fixing ring T11 which engages with the outside of the neck R1. The fixing ring T11 can be a ring to be screwed, snapped on, crimped, etc. The head body T1 also includes, inside the fixing ring T1, a socket T12 in which is engaged a support piece T2 forming a seat for a ball T21. A dip tube T22 is also connected to this support piece T2. The dip tube T22 extends inside the tank R to near its bottom. Above the support piece T2, the head body T1 forms a fluid product duct T13 which is connected to a mixing chamber T14. The head body T1 also forms a connection housing T15 in which is engaged a connection T3 on which is mounted an air flush T4, for example in the form of a crushable pear. Thus, the interior of the air flush T4 communicates with the mixing chamber T14 through the connector T3 engaged in the connection housing T15. On the other hand, the mixing chamber T14 communicates with a mounting chamber T16 in which is received a fluid product distribution module M. It may also be noted that the head body T1 forms a vent duct T17 which connects the mounting housing T16 with the inside of the tank R between the socket T12 and the body R1. This is the general structure of the dispensing head T, which should not be considered unique within the framework of the present invention, which is more particularly attached to the design of the fluid dispenser module M.
    Reference will now be made to FIGS. 2 and 4 which respectively represent the dispensing head T (without the air flush T4) and the fluid dispenser module M in the rest position, that is to say when the flush of air T4 is not subjected to any crushing force. As mentioned above, the distribution module M is positioned in the mounting housing T16 so as to communicate both with the mixing chamber T14 and the venting duct T17.
    In FIG. 4, it can be seen that this distribution module M comprises a mounting body 1 which is fixedly received in the mounting housing T16. This mounting body 1 comprises an inlet sleeve 12 internally defining a fluid product inlet 13 which is positioned directly downstream of the mixing chamber T14. The mounting body 1 also forms a vent hole 11. The distribution module M also includes an insert part 2 which is fixedly received inside the mounting body 1. This insert part 2 comprises a barrel sliding 20, a pin 25 and an annular flange 26 which surround the pin 25 so as to form between them an annular space 24. The sliding barrel 20 comprises a cylindrical inner wall and an outer wall which engages with the inner wall of the mounting body 1. The sliding barrel 20 comprises several through openings, namely a first lateral opening 21, a second lateral opening 27 and a third lateral opening 28. The insert 2 also forms a fourth lateral opening 23 at level of the annular flange 24, so that the fourth lateral opening 23 gives directly into the annular space 24. On the other hand, the insert 2 comprises u ne first external groove 22 which connects the first lateral opening 21 with the fourth lateral opening 23. The first groove 22 is completed by the internal wall of the mounting body 1 so as to thus form a connecting duct which connects the first opening 21 with the fourth opening 23. On the other hand, the insert 2 forms a second groove 29 which connects the third lateral opening 28 with the outside. This groove 29 is completed by the internal wall of the mounting body 1 so as to form an outside air intake duct.
    The distribution module M also comprises a movable member 3 which has a substantially H-shaped section. More specifically, this movable member 3 comprises a first annular piston lip 32 and a second annular piston lip 33 which are designed to slide from sealingly inside the sliding barrel 20. The two lips 32 and 33 are connected together by a reduced diameter section 34 which does not come in sealed sliding with the sliding barrel 20. The movable member 3 also comprises a partition wall 31 which prevents any passage through the movable member 3.
    The distribution module M also comprises a spring 4 which is disposed inside the sliding barrel 20 and bears on the one hand on the insert part 2 and on the other hand on the partition wall 31 of the movable member 3 passing through the second piston lip 33.
    In this embodiment, the distribution module M also includes a nozzle 5 which is engaged in the annular space 24 around the pin 25 inside the annular flange 26. This nozzle 5 has a completely conventional design with a dispensing orifice 50, a swirl chamber 51, several swirl channels 52 and one or more connecting passage (s) 53. This nozzle makes it possible to dispense the fluid product in the form of fine droplets. One can however imagine other types of sprinklers without departing from the scope of the invention.
    In Figure 4, we see the distribution module M in the rest position, in which the spring 4 pushes the movable member 3 against a radial shoulder 14 formed at the downstream end of the fluid inlet 13. More specifically , it is the first piston lip 32 which thus comes into contact supported by the spring 4 against this radial shoulder 14 so as to create a sealed annular contact. This sealed annular contact is added to the radial annular contact of the first piston lip 32 with the sliding barrel 20. This creates a double seal, both axial and radial. It should above all be noted that the first lateral opening 21 is closed by the movable member 3, since it is located between the two piston lips 32 and 33. Thus, the fluid inlet 13 cannot communicate with the first lateral opening 21. On the other hand, it can be seen that the second piston lip 33 closes the second lateral opening 27 which communicates with the vent duct D17 through the hole 11. In short, the first piston lip 32 cuts the communication between the fluid inlet 13 and the first lateral opening 21 and the second piston lip 33 isolates the first lateral opening 21 and literally closes the second lateral opening 27 in the rest position (Figures 2 and 4).
    It can also be said that the fluid inlet 13, the first lateral opening, the first groove 22, the fourth lateral opening 23, the annular space 24, the connecting passages 53, the swirl channels 52, the swirl 51 and the dispensing orifice 50 together form a fluid product flow path Cp which is cut by the movable member 3. On the other hand, it can be said that the second lateral groove 29, the third lateral opening 28 , the interior of the sliding barrel, the second lateral opening 27 and the lateral hole 11 form an air vent path Ca which is cut at the second lateral opening 27 by the movable member 3.
    We will now refer to Figures 3 and 5 to describe the distribution module M during a fluid product distribution phase. To activate this distributor, the user grasps the air flush T4 and crushes it so as to generate a flow of pressurized air through the narrow connector and the mixing chamber T14. This barrel of pressurized air enters the distribution module M through the fluid product inlet 13. This barrel of pressurized air creates a Venturi effect which results in sucking the fluid product stored in the reservoir R through the dip tube 22, the support part T2 by pushing the ball T21 and the conduit T13 which opens into the chambreο mixing chamber T14. Consequently, the fluid product coming from the tank R mixes with the flow of pressurized air coming from the flushing air T4 at the level of the mixing chamber T14. Therefore, it is a biphasic mixture of fluid and air which passes through the fluid inlet 13. As this biphasic mixture is under pressure, it will move the movable member 3 inside the sliding barrel 20 by compressing the spring 4. The first piston lip 32 will thus move in sealed sliding inside the sliding barrel 20 until it reaches the level of the first lateral opening 21. The sealed stroke of the movable member 3 defines a precompression stroke during which the fluid product flow path Cp is not yet open. It is therefore necessary for the two-phase mixture to reach a certain pressure threshold to move the first piston lip 32 at or even beyond the first lateral opening 21, as shown in FIG. 5. The flow path for the fluid product Cp is then established by connecting the fluid inlet 13 to the first lateral opening 21 passing through a portion of the sliding barrel 20. The fluid P can thus travel to the dispensing orifice 50 where it is dispensed under pulverized form. Thus, the movable member 3 behaves like a valve by masking and unmask selectively the first lateral opening 21. It can be considered that the sliding barrel 20 forms a valve seat on which the first piston lip 32 slides in sealed manner.
    It should also be noted that the vent path Ca is also open since the second lateral opening 27 and the third lateral opening 28 can communicate. Indeed, the two piston lips 32 and 33 are located on either side of these two lateral openings 27 and 28 so that the narrowed section 34 of the movable member 3 is positioned at its two lateral openings 27 and 28, thus forming a connecting passage between the two openings. Outside air can thus enter the interior of the tank through the second groove 29, the third lateral opening 28, the interior of the sliding barrel 20, the second lateral opening 27, the lateral hole 11, the passage vent T17 and between the socket T12 and the neck R1.
    As soon as the crushing force on the flushing air T4 is released, the pressure at the level of the fluid product inlet 13 drops and the spring 4 pushes the movable member 3 back into its rest position in FIG. 4. The fluid product flow path Cp is again cut, as is the vent path Ca. It can be noted that the two paths Cp and Ca are established simultaneously and cut simultaneously.
    Figures 6 and 7 show a second embodiment for the fluid dispensing head. This dispensing head T ′ may be identical or similar to that of the first embodiment on certain points, and in particular its entire lower part, forming the fixing ring T11, the socket T12, the support piece T2, the connecting duct T13, the mounting housing T16 and the vent pipe T17. On the other hand, this dispensing head T 'differs from the first dispensing head T in that it comprises a flexible dome T5 which is mounted in leaktight manner by means of an anchoring flange T55 on the head body T1 '. This flexible dome T5 includes an elastically deformable actuating wall T52 which internally defines a pump chamber T50. By deforming the actuating wall T52, as shown in FIG. 7, the internal volume of the chamber T50 decreases, and the fluid product which it contains is pressurized so that it is discharged through a connection chamber T14 'in the fluid inlet 13 of the dispensing module M. The fluid then pushes the movable member 3, as shown in Figure 5, so that the fluid can flow through the dispensing module M to be sprayed through the dispensing orifice 50. During this dispensing phase, the pressure of the fluid product of course presses the ball 21 on its seat. As soon as the user releases his pressure on the deformable actuating wall T52, a vacuum is created inside the chamber T50 which has the effect of strongly pressing the movable member 3 against the radial shoulder 14 and lifting the ball T21 so that the fluid coming from the reservoir R can then rise through the dip tube 22, the connecting pipe 13 to reach the pump chamber T50.
    Referring to Figures 8a and 8b, we see a fluid dispenser type "squeeze bottle", that is to say with a fluid reservoir R "comprising a deformable wall R2, which the user can grasp with one hand to crush it. The distributor also includes a distribution head T "which is mounted on an opening of the tank R" by means of a fixing ring T11. This Head T ”also includes a tube holder T2” into which is fitted one end of a dip tube T22 which extends into the tank R ”near its bottom. The head T ”also forms a connection duct T13 and a connection chamber T14” upstream of the tube holder T2 ’. This chamber T14 ”communicates with a mounting housing T16 in which is received a fluid product distribution module M, which can be identical to that of the previous figures. Finally, the head T "includes a venting duct T17 which connects the housing T16 to the tank R".
    By crushing the deformable wall R2, the fluid stored in the reservoir R ”is discharged through the dip tube T22, the connection conduit T13 and the connection chamber T14” to reach the inlet 13 of the module M, as visible in Figure 8b. The module M then behaves in the same manner as previously described with reference to FIGS. 3, 5 and 7.
    This third embodiment aims to show that the module M of the invention can be implemented in various applications: pear dispenser, collapsible dome dispenser or even "squeeze bottle".
    In FIG. 9a, there is seen a fluid product distribution module M ’having a different design. Indeed, this module M 'includes:
    a mounting body T intended to be fixedly received in a mounting housing for a dispensing head, this mounting body T defining a first sliding barrel 15 'and a second sliding barrel 16', as well as a first opening 1T, a second opening 18 'and a groove 19' at the level of the first sliding barrel 15 ',
    a movable member 2 'mounted in leaktight sliding in the two sliding barrels 15' and 16 ': the movable member 2' comprising two lips 22 'and 23' in sealed sliding contact in the first sliding barrel 15 'and another lip 21 'in leaktight sliding contact in the second sliding barrel 16',
    - a valve member 3 ’fixedly mounted in the movable member 2’: the valve member 3 ’comprising a valve lip 31’ sealingly pressed against a valve seat 20 ’of the movable member 2’,
    - a spring (4) which acts between the mounting body 1 'and the movable member 2' to urge the movable member 2 'in the rest position.
    Optionally, the mounting body 1 ’can be provided with a nozzle 5’, which can spray the fluid product into fine droplets. This 5 ’nozzle may include a spray wall pierced by several spray holes of reduced diameter (1 to 100 microns).
    It can be noted that a suction chamber Cs is formed at the level of the second sliding barrel 16 ’. This chamber Cs has a variable volume due to the fact that the movable member 2 ’, with its valve member 3’, moves by sliding in the second sliding barrel 16 ’.
    When the module M ’is at rest (FIGS. 9a and 9e), the two lips 22’ and 23 ’are positioned on either side of the opening 11’, so as to isolate it. On the other hand, the valve lip 31 'is sealingly pressed against its seat 20'.
    When fluid under pressure arrives at the inlet 13 'of the module M', the movable member 2 ', with its valve member 3', moves by sliding in the second sliding barrel 16 ', as shown in FIG. 9b, so that the two openings 11 'and 18' communicate with each other through the inside of the barrel 15 ', between the two lips 22' and 23 ', at the level of the thinned part 24'. A Ca venting path is thus established through the groove 19 ’, the opening 18’, the interior of the barrel 15 ’and the opening 11’. External air can then be supplied along this Ca venting path to the fluid reservoir, in order to balance its internal pressure.
    It should be noted in FIG. 9b that the valve lip 31 ’is still in sealed contact against its seat 20’. It is only when the pressure of the fluid product reaches a determined precompression threshold that the valve lip detaches from its seat 20 ’, as shown in FIG. 9c. A fluid product flow path Cp is thus established through the inlet 13 ', the passage 35', the gap between the valve lip and its seat 20 ', the suction chamber Cs and the nozzle 5' . Note that the Ca vent path is also established at this time.
    As soon as the pressure of the fluid product falls below the determined precompression threshold, the valve lip 31 ′ finds its sealed support against its seat 20 ′, thus breaking the path of flow of fluid product Cp, while the path d 'venting Ca is still established, as shown in Figure 9d, which is identical to Figure 9b.
    Finally, when the fluid product no longer exerts pressure on the module M ’, it returns to its rest position, as shown in FIG. 9e, which is identical to FIG. 9a. The operating cycle is completed.
    During this cycle, the suction chamber Cs sees its volume vary: in fact, at rest, its volume is maximum and in FIGS. 9b, 9c and 9d, its volume is minimal. This means that the increase in volume of the suction chamber Cs passing from FIG. 9d to FIG. 9e has the effect of creating a depression in the suction chamber Cs which will suck the fluid product located at the level of the nozzle. 5 ', and thus empty it, at least partially. This suction or "sniffing" effect is particularly useful and effective with nozzles having micro-spray holes (1 to 100 microns).
    Thus, this module M ’combines several functions: fluid valve, venting of the tank and evacuation of the nozzle. It should be noted that the evacuation function of the nozzle could be implemented independently of the other two functions and be the object of protection in itself, especially in association with a micro-hole spray nozzle.
    Thanks to the distribution module Μ, M ’, outside air can penetrate inside the fluid reservoir during the fluid dispensing phase by taking the Ca vent path.
    Thanks to the distribution module Μ, M ’of the present invention, it is possible to simplify the design of a pump, since the outlet valve is formed by the distribution module. In addition, this module Μ, M ’also manages the venting of the tank. Its installation in the T16 mounting housing is extremely simple, since it is simply axially engaged and held in place by friction forces, or even 10 attachment profiles at the level of the inlet sleeve 12.
