Definitions
- the present invention relates to a fluid product dispensing device. More particularly, the present invention relates to a single-dose nasal fluid delivery device for dispensing a pharmaceutical fluid product into the nose of a user via a single nasal spray.
- a disadvantage of existing nasal fluid delivery devices is the risk of unwanted actuation if the device falls.
- the present invention aims to provide a fluid product dispensing device which does not reproduce the aforementioned drawbacks.
- the present invention aims to provide a fluid product dispensing device which avoids the risks of unwanted actuation, for example in the event of the device falling.
- the present invention also aims to provide such a device which is simple and inexpensive to manufacture and assemble.
- the device comprises a hollow insert inserted and fixed in said dispensing head, said insert comprising a drilling tip for piercing said piston plug and thus connecting said reservoir to said dispensing orifice during actuation.
- said drilling tip is produced separately then assembled in said insert, in particular by force fitting or by overmolding.
- said drilling tip is molded in one piece with said insert.
- said blocking member comprises a plate provided with a hole through which said actuating body extends, said hole defining an edge which cooperates in the blocking position with a groove of said actuating body, the diameter of said hole being greater than the external diameter of said actuating body, said plate being movable radially between a blocking position, in which said edge is disposed in said groove, and a release position, in which said plate is offset laterally, so that said actuating body can slide axially in said hole.
- said radial flange of said dispensing head comprises at least one fin extending at rest axially upwards and deformable downwards by the user.
- said plate has an axial projection which extends axially upwards, and said at least one fin has on its lower surface a pin adapted to cooperate with said axial projection so that when the user presses on said fin, said pin pushes said axial projection laterally which will move said plate from its blocking position to its release position.
- the device comprises two diametrically opposed fins.
- the device comprises an actuating body receiving said reservoir, said actuating body comprising a radial disk connected to said actuating body by one or more breakable bridges, said radial disk cooperating with a part of said dispensing head to form a precompression threshold that the user must overcome during actuation to break said breakable bridges and thus activate the device.
- said reservoir contains a single dose of fluid product distributed in a single actuation.
- Figure 1 is a schematic view in perspective of a fluid product dispensing device according to an advantageous embodiment, in position before actuation of the blocking member
- Figure 2 is a schematic cross-sectional view of the device of Figure 1
- Figure 3 is a view similar to that of Figure 1, in position after actuation of the blocking member and with the piston in the rest position
- Figure 4 is a schematic cross-sectional view of the device of Figure 3
- Figure 5 is a view similar to that of Figure 3, after actuation of the piston
- Figure 6 is a schematic cross-sectional view of the device of Figure 5
- Figure 7 is a schematic exploded perspective view of the device of Figure 1.
- axial and radial refer to the longitudinal central axis A of the device.
- up and down refer to the upright position of the device shown in the figures.
- the device is a single dose, that is to say the reservoir contains a single dose of fluid product distributed in a single actuation.
- a reservoir 10 containing fluid product to be distributed is arranged inside a body forming a dispensing head 20.
- This dispensing head 20 comprises a dispensing orifice 21 oriented axially .
- This dispensing orifice 21 serves to distribute a dose of fluid product out of said dispensing head 20 when the device is actuated by a user.
- the dispensing head 20 comprises an elongated nasal tip comprising at its proximal axial end said dispensing orifice 21, as well as a lateral body 24, connected to said nasal tip 22 at the level of a radial flange 23.
- the channel 61 ends at its lower end with a drilling tip 40.
- This drilling tip 40 can be molded in one piece with the insert 60. Alternatively, it could be made separately, for example in metal or another synthetic material as that of the insert, then assembled in said insert, for example by force-fitting or by overmolding.
- the drilling tip 40 extends axially downwards beyond the elongated cylindrical body of the insert 60.
- the reservoir 10 is advantageously formed by a hollow and blind body, comprising a single opening defining a neck 11 and closed by a piston cap 50.
- the reservoir 10 contains a single dose of product fluid to distribute a single actuation of the device.
- the piston-plug 50 can be moved in the reservoir 10 between a rest position and an end of actuation position to distribute said fluid product through the distribution orifice 21 during actuation.
- Actuation means 30 are advantageously provided to enable the device to be actuated.
- these actuating means 30 comprise an actuating body 31 movable relative to the dispensing head 20, said actuating body 31 cooperating with said reservoir 10 to move it axially relative to the distribution head 20, towards the distribution orifice 21.
- the user presses on the bottom wall 32 of the actuating body 31, to move the latter together with the reservoir 10 axially in the dispensing head 20, thus causing the piercing of the piston-plug 50 by the piercing tip 40 and the distribution of the dose of fluid through the distribution orifice 21.
- the user could press directly on the bottom of the reservoir 10.
- the reservoir 10 is therefore pushed axially towards the distribution orifice 21, so that the drilling tip 40 will pierce the piston plug 50.
- the contents of the reservoir 10 are then connected to the distribution orifice 21 and the user's support on the actuating body 31 moves the piston cap 50 in the reservoir 10 to ensure the distribution of the fluid product.
- the present invention could also be applied to devices without a drilling tip adapted to pierce a piston plug, as for example described in the documents WO2019122671, WO2021 069823, WO2022090675, WO2022101589, WO2022208014.
- the actuating body 31 comprises a radial disc 35 connected to the actuating body by one or more breakable bridges 36, in particular visible in FIG. 17. This disc 35 cooperates with a part of the dispensing head 20 to form a precompression threshold that the user must overcome during actuation to break the breakable bridges 36 and thus activate the device.
- breakable bridges 36 provide security against unwanted actuation, but during an axial fall of the device, it cannot be excluded that the inertia of the device is sufficient to break the breakable bridges and thus the safety provided by the bridges. breakable 36 is not sufficient.
- the device comprises a blocking member 200 which blocks the axial movement of the reservoir 10 in the dispensing head 20.
- the blocking member 200 is movable and/or deformable between a blocking position and a release position. . The user must first move and/or deform the blocking member 200 towards its release position before being able to operate the device by moving the reservoir 10 axially in the dispensing head 20.
- the device comprises fins 210 arranged on or above the radial flange 23, said fins being movable between a rest position, in which the blocking member 200 is in the blocking position, and a position support, in which the blocking member 200 is moved and/or deformed in the release position.
- the invention provides that the movement and/or deformation of the blocking member 200 towards its release position is carried out when the user takes the device in hand, by pressing his fingers on the radial flange 23 of the dispensing head 20.
- the present invention makes it possible to guarantee safety in the event of the device falling, without requiring additional movement from the user to activate the device.
- the user takes the device in hand he places two fingers on the fins 210 arranged on or above the radial flange 23 of the dispensing head 20, and presses with the thumb on a distal axial bottom 32 of said body 'actuation 31.
- it will first move with its fingers the fins 210 towards their support position, which moves and/or deforms the blocking member 200 towards its release position, and then the thumb will move the actuating body 31 to distribute the dose.
- the blocking member 200 is assembled around the actuating body 31, under the radial flange 23.
- the blocking member 200 comprises a plate 201 provided with a hole
- the plate 201 has an axial projection 203 which extends axially upwards.
- the radial flange 23 of the dispensing head 20 comprises at least one fin 210 extending at rest axially upwards relative to the radial plane formed by the radial flange 23, and deformable downwards by the 'user.
- this deformation is elastic, the fin 210 being biased towards its rest position and deformed towards its support position.
- the fin 210 has on its lower surface a lug 211 adapted to cooperate with the axial projection 203 of the plate 201.
- the lug 211 will push the axial projection
- the device can then be actuated by pressing axially on the bottom 32 of the actuating body 31.
- an advantage of the present invention is that it does not require additional movement or displacement of a part of the device: the user normally takes the device in hand, with his thumb on the bottom wall 32 of the actuating body 31 and his fingers on the fins 210 arranged in the radial flange 23 of the dispensing head 20. By performing the usual actuation gesture, he will first move the fins 210 to unlock the blocking member 200, then actuate the device.
