[0054] The terms "axial", "radial", "horizontal" and "vertical" are used with reference to the longitudinal center axis of the device. The terms "high", "low", "upper" and "lower" are used with reference to the longitudinal center axis of the device. Figure 3 and Figure 4 The representation refers to the upright position of the device.

[0055] The invention is primarily directed to a device that authorizes / inhibits the delivery of a dose by releasing / blocking the actuation of a pusher that allows the fluid dispenser to be actuated.

[0056] The fluid product dispensing device shown in the figure comprises a fluid product dispenser 1 which is advantageously of a standard type. The dispenser 1 comprises a reservoir 2 for accommodating the fluid product and a dispensing member 3 such as a pump or a valve, a portion of which can be axially moved relative to the reservoir 2. The dispensing member 3 is fixed to the reservoir 2 by a fixing ring 4. The dispensing member 3 is actuated when the pusher moves axially downward relative to the reservoir 2. Generally speaking, when the reservoir 2 does not contain a propellant gas, a dispensing pump is used, and when the reservoir 2 contains a propellant gas, a metering valve is used. These two types of dispensing members are well known to those skilled in the art and will not be described in more detail below, since such dispensing members are not directly involved in the present invention.

[0057] The fluid dispenser device also comprises an internal body 10 receiving the dispenser 1 , and an external body 120 fixed to the internal body 10 and housing the electronic control module 90 .

[0058] The internal body 10 comprises a hollow cylinder 11 which is axially open on the lower side and has a connection, which is advantageously realized in the form of a thread 12 on the outer surface of the lower opening. This hollow cylinder 11 is used to receive the reservoir 2 of the dispenser 1. A cover 5 is provided to fix the dispenser 1 in the internal body 10. This cover 5 comprises a complementary connection, which is advantageously realized in the form of an internal thread 6, suitable for cooperating with the connection of the internal body 10. Therefore, in order to install the dispenser 1 in the device, the reservoir 2 is inserted into the hollow cylinder 11 of the internal body 10. The cover 5 is then screwed onto said internal body 10. The assembly method is described in detail in detail in the accompanying drawings. Figure 2 This embodiment allows to easily replace a dispenser 1 with an empty reservoir by a full one. The device, in particular the electronic control module 90, can then be reused instead of being discarded.

[0059] On the upper side, the inner body 10 comprises a disc platform 13 and a hollow axial extension 14 extending axially upward from the disc platform 13. The radial dimension of the hollow axial extension 14 is reduced compared to the inner diameter of the hollow cylindrical body 11. The axial extension can be integrally formed with the inner body 10 or can be manufactured separately and then fixed to the inner body 10 in any suitable manner. When the dispenser 1 is arranged in the inner body 10, at least a part of the dispensing member 3 passes through the hollow axial extension 14.

[0060] The outer body 120 is hollow and can have any outer shape. In the example shown, the shape of the outer body 120 is approximately rectangular, partially corresponding to the shape of the disk table 13 of the inner body 10. The outer body 120 is fixed to the inner body 10 in a suitable manner, for example by snapping. Advantageously, the outer body 120 includes one or more windows 121, for example Figures 1 to 4 The window shown in the figure allows viewing of the screen 91 of the electronic control module 90. The screen can display information such as instructions for use, battery charging information, etc.

[0061] The outer body 120 also comprises an opening 122 for receiving the control button 85. In a variant, the control button can be replaced by a control zone of another display screen visible on the screen 91 or in another window. The control zone can integrate fingerprint detection means to allow only authorized persons to actuate the device, thus preventing any accidental actuation, for example by children. Other identification means can also be envisaged, such as facial recognition. The control button or control zone can also be replaced by other means: voice command, remote unlocking by a third party (for example a doctor) or a command managed by the software or timer of the electronic control module.

[0062] A cover 30 is provided for fixing on the disk table 13 of the inner body 10, the cover 30 comprising a hollow cylinder 31 and a radial flange 32. The hollow cylinder 31 comprises an inner profile 35, the inner profile comprising a first window 350 and a second window 351, the second window being separated from the first window 350 by a radial column 352. In a variant, the profile 35 can be provided on the inner body 10.

[0063] A poussoir 20 with a dispensing orifice 21 is mounted in the hollow cylindrical body 31 of the cap 30 and is axially movable relative to the internal body 10 between a rest position and an actuated position, in which the poussoir 20 is axially moved downward relative to the internal body 10. Advantageously, the poussoir comprises a nasal spout 22 which terminates at its upper end in the dispensing orifice 21 and comprises, on its lower side, an axial skirt 23 having a radial pressing surface 230 which the user can press in order to actuate the dispenser 1. At least one axial claw 24 extends axially downward from a lower radial edge 231 of the axial skirt 23 in order to fix the poussoir 20 in the hollow cylindrical body 31 of the cap 30, for example by snapping. Figure 8 In the example of the embodiment of the present invention, there are two diametrically opposed axial claws 24. An axial finger 27 also extends axially downward from the lower radial edge 231 of the axial skirt 23, the function of which will be described below. Figure 8 In the example of FIG. 2 , the axial finger 27 is arranged at 90° to each of the two diametrically opposite axial claws 24 .

[0064] Internally, the pusher 20 comprises a hollow tube 25 which will cooperate with the dispensing member 3 and which opens into the dispensing orifice 21 , advantageously with a spray profile arranged just upstream of said dispensing orifice for generating the spray. Below said radial pressing face 23 there is arranged at least one axial stud 26 . Figure 8 In the example of FIG. 4 , there are four axial columns 26 (three of which are visible) distributed around the periphery. The function of these axial columns will be described below.

[0065] The device further comprises a locking ring 40 , a gear 50 matched with the locking ring 40 , a spring 60 for the locking ring 40 , and a motor wheel 70 connected with a motor 80 , wherein the motor wheel 70 matches with the gear 50 .

[0066] The locking ring 40 , the gear 50 , the spring 60 and the motor wheel 70 are disposed on the disk table 13 of the inner body 10 and are held in place by the cover 30 .

[0067] The locking ring 40 is rotatably mounted around the axial extension 14 of the inner body 10 between a locking position and a release position. The spring 60 pushes the locking ring toward its locking position. Fig.13 and 15 As shown, advantageously, the spring is fixed on one contact post 46 of the locking ring 40 and on the other hand on a second contact post 36 provided on the disk table 13 of the inner body 10. The locking ring 40 cooperates with the pressing member 20 to selectively prevent or allow the axial movement of the pressing member 20.

[0068] The locking ring 40 comprises a hollow sleeve 41 having an axially flexible sheet 42 at a lower axial edge 411, the axially flexible sheet 42 extending coaxially outside the hollow sleeve 41. The axially flexible sheet 42 comprises a tooth 420 protruding axially upwards and an opening 421 arranged behind the tooth 420. In the locked position of the locking ring, the tooth 420 is arranged in the first window 350 of the cover 30, as shown in FIG. Fig.17 , 19 As can be seen in Figures 2 and 22. When the locking ring 40 moves toward its release position, as shown Fig.19 As indicated by the arrow in FIG. , the axially flexible sheet 42 is deformed axially downward to allow the tooth 420 to pass under the radial column 352 of the cover 30 so that the tooth is positioned in the second window 351, as shown in FIG. Fig.18 Advantageously, during the unlocking cycle, the rotation of the motor 80 transmitted by the gear 50 produces an angular overtravel of the locking ring 40 and thus an offset between the teeth 420 and the radial posts 352, as in Fig.23 This ensures that when the motor 80 no longer applies torque, the teeth 420 will snap behind the radial posts 352 and the second set of teeth 52 of the gear 50 will no longer mesh with the teeth 45 of the locking ring 40. This ensures reliable operation despite the manufacturing tolerances of the various parts. Since the spring 60 pushes the locking ring 40 towards its locked position, once the locking ring 40 reaches the released position, the spring will attempt to return the locking ring to the locked position, but this movement will be prevented by the radial posts 352 against which the teeth 420 of the flexible sheet 42 are abutting, as shown in FIG. Fig.24 Visible in.

[0069] The locking ring 40 comprises at least one radial protrusion 43 extending radially outwards from the hollow sleeve 41. In the example shown in the figures, there are four radial protrusions 43 distributed around the circumference of the hollow sleeve 41. In the locking position, these radial protrusions 43 cooperate with the axial studs 26 of the pusher 20 to prevent the axial movement of the pusher towards its actuated position. On the contrary, in the release position, each radial protrusion 43 is angularly offset relative to the corresponding axial stud 26, thereby allowing the axial movement of the pusher 20 towards its actuated position. Fig.15 This embodiment shown in the figures visible in FIG. 1 with four radial projections 43 cooperating with four axial studs 26 makes the device particularly robust and prevents any unauthorized actuation of the device.

[0070] On the side opposite to the flexible sheet 42, the locking ring 40 comprises a platform 44 supporting some teeth 45 which cooperate with the gear 50 when the gear 50 moves the locking ring 40 towards its release position. The platform 44 also advantageously supports a contact pin 46 fixed to the spring 60. Advantageously, the locking ring 40 comprises a detection member suitable for cooperating with the electronic control module 90 to inform the module of the position of the locking ring. In the example, the detection member comprises an axial extension 47 extending axially downwards from said platform 44.

[0071] The gear 50 includes a first tooth set 51, which includes a plurality of teeth distributed over the entire circumference of the gear 50. Axially above the first tooth set 51, the gear 50 includes a second tooth set 52. The second tooth set only includes some teeth on only a portion of the circumference. Fig.10 In the example shown, the second set of teeth 52 comprises three teeth. The second set of teeth 52 cooperates with the teeth 45 of the locking ring 40 so as to rotate the locking ring from its locking position toward its release position, as in Fig. 20 and 21 Can be seen in.

[0072] The motor wheel 70 includes a set of teeth 71 that cooperate with the first set of teeth 51 of the gear 50. Therefore, when the motor 80 rotates the motor wheel 70 in a rotational direction, the motor wheel rotates the gear 50, thereby driving the locking ring 40 from the locking position toward its release position.

[0073] The electronic control module 90 is fixed to the support 81, which is in turn fixed to the inner body 10, and is received as a whole inside the outer body 120. The electronic control module 90 controls the motor 80, which is also fixed to the support 81 and cooperates with the motor wheel 70 to rotate it.

[0074] The motor 80 may be a 3V DC gear motor adapted to rotate a motor shaft connected to the motor wheel 70. Such a motor may be powered in any suitable manner, for example by means of a rechargeable or non-rechargeable battery or battery pack. Preferably, when the motor 80 is controlled, it rotates the motor wheel 70 so that the gear 50 makes one full revolution. This first causes the locking ring 40 to rotate from its locking position towards its release position, and then causes the second set of teeth 52 of the gear 50 to disengage from the teeth 45 of the locking ring 40. Thus, once the locking ring 40 is in its release position, it is no longer connected to the motor 80.

[0075] The electronic control module 90 comprises suitable electronic components, such as in particular a microprocessor, to operate the device, in particular the motor 80 and the screen 91. Advantageously, the electronic control module 90 comprises a switch (not shown) for detecting the movement and / or position of the locking ring 40, in particular its axial extension 47. It is thus possible to detect the various activation phases, in particular the return of the locking ring 40 to its locking position after the dispenser 1 has been activated and thus a dose of fluid has been dispensed. This information can be used to lock the device for a predetermined period of time.

[0076] Therefore, the electronic control module 90 may include a time delay component to allow new actuation only after the expiration of a predetermined period. The time delay component may include an internal clock of a microprocessor in particular. If necessary, a real-time clock component may be added thereto. This temporary locking preferably acts on the control of the motor 80, thereby preventing the motor from rotating to move the locking ring 40 from its locking position toward its release position. In a variation, the control button 85 may be deactivated or locked within a predetermined time. Advantageously, only authorized personnel, such as medical personnel, may modify the locking time by accessing the electronic control module or via the screen 91. Advantageously, the screen 91 indicates how much time is left before the next dose can and / or must be taken. If necessary, a sound and / or visual signal may also be provided if the user still presses the control button in order to attempt to unlock the device.

[0077] The operation of the apparatus shown in the drawings will now be described in more detail.

[0078] In a typical actuation cycle, the user holds the device in a rest position, such as Figure 3 In this position, the user cannot move the pressing member 20 axially downwards, because the pressing member is locked by the locking ring 40 in the locked position.

[0079] To actuate the device, the user must first send a command to the electronic control module 90 to move the locking ring 40 from its locking position toward its release position. Figure 3 The user presses the control button 85 in the direction of the arrow F1 in FIG. 8 . This pressing will rotate the motor 80 and thus the motor wheel 70, which will cause the gear 50 and thus the locking ring 40 to move from Fig.15 , 17 , 19 and 22, the locking position visible in the Fig.16 , 18 23. This movement of the locking wheel 60 will load the spring 60, which will then act to return the locking ring 40 toward its locked position. However, since the locking ring 40 is locked in the released position by abutting against the teeth 420 of the radial posts 352 of the cover 30, the locking ring cannot return to its locked position under the force exerted by the spring 60.

[0080] The user can then Figure 4 The axial actuation force is applied to the push piece 20 in the direction of the arrow F2 in the figure to move the push piece axially downward. This will actuate the dispensing member 3 and discharge a dose of fluid product through the dispensing orifice 21. The actuation of the motor 80 has caused the gear 50 to rotate a full circle, so that in the release position, since the second tooth set 52 of the gear 50 is no longer connected to the teeth 45 of the locking ring 40, the locking ring 40 is no longer connected to the motor 80. In a variant, the gear 50 may not rotate a full circle each time the motor 80 is actuated, but rotate any angular path, such as half a circle. In this case, the number of teeth 45 of the locking ring 40 and the number of teeth of the second tooth set 52 of the gear will be adjusted accordingly.

[0081] From the start of actuation, the pusher 20 is lowered axially relative to the locking ring 40, and the axial fingers 27 of the pusher will cooperate with the teeth 420 of the flexible sheet 42. Fig.25 As can be seen in FIG. 1 , the axial finger 27 will push the tooth 420 axially downward so that the tooth will disengage from the radial post 352. When the tooth 420 is no longer locked by the radial post 352, the locking ring 40 is pushed toward its locked position by the spring 60. However, the locking ring cannot return to this locked position because Fig.28 In the intermediate position visible in FIG. 4 , the radial projections 43 of the locking ring 40 remain locked against the radial studs 26 of the push piece 20. Only when the push piece 20 returns to the rest position can the locking ring 40 automatically return to the locked position under the action of the spring 60. Preferably, the teeth 420 are disengaged from the radial studs 352 at the beginning of the actuation stroke of the push piece 20, which ensures locking even in the case of an incomplete actuation stroke. It is therefore not possible to dispense multiple consecutive partial doses. After the teeth 420 have been disengaged, when the locking ring 40 is in the rest position, the locking ring 40 is automatically returned to the locked position under the action of the spring 60. Fig.28 When the pressing member 20 is in the middle position, the pressing member 20 can continue its full actuation stroke until the actuation position, at which time the axial finger-shaped member 27 passes through the opening 421 of the flexible sheet 42, as can be seen in Fig.26 Visible in.

[0082] After actuation, the user releases his pressure on the pusher 20 which will be returned towards the rest position by the dispenser member 3 and in particular by its return spring (not shown).

[0083] The device then returns to its rest position and the next actuation is possible only after the expiration of a locking period predetermined by the electronic control module 90 .

[0084] Although the invention has been described with reference to advantageous embodiments, it will of course be possible for a person skilled in the art to make various modifications thereto without departing from the scope of the invention as defined in the appended claims.
