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 present invention therefore relates to a fluid product dispensing device comprising a reservoir containing fluid product and a dispensing head provided with a dispensing orifice, said reservoir being axially movable relative to said dispensing head during a actuation, a piston cap being movable in said reservoir to distribute fluid product through said distribution orifice during actuation, said reservoir being received in an actuation body, said actuation body comprising a radial ring connected to said actuating body by one or more breakable bridges, said radial ring cooperating with a part of said distribution head to form a precompression threshold which the user must overcome during actuation to break said breakable bridges and thus actuate the device , each bridge breakable being elastically deformable up to a breaking point, to absorb forces exerted on said breakable bridges which are lower than a predetermined threshold corresponding to said breaking point.
- each breakable bridge comprises at least one curvature, allowing an elongation of said breakable bridge by deformation of said at least one curvature.
- each breakable bridge has a curvature, approximately V-shaped.
- each breakable bridge has two curvatures, approximately in the shape of an S.
- each breakable bridge is of frustoconical shape, narrowing towards said actuating body.
- each breakable bridge has a contact surface with said radial ring which is greater than the contact surface with said actuating body.
- said reservoir is formed by a hollow and blind body, comprising a bottom and a single opening which, in the rest position, is sealed in a sealed manner by said piston plug.
- 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 reservoir contains a single dose of fluid product distributed in a single actuation.
- Figure 1 is a schematic view in vertical cross section of a fluid product dispensing device according to an advantageous embodiment, in the rest position
- Figure 2 is a schematic perspective view of an actuator body of the state of the art
- Figure 3 is a schematic horizontal cross-sectional view of the actuator body of Figure 2
- Figure 4 is a schematic perspective view of an actuating body according to a first advantageous embodiment
- Figure 5 is a schematic perspective view of an actuating body according to a second advantageous embodiment
- Figure 6 is a view schematic perspective view of an actuating body according to a third advantageous embodiment
- Figure 7 is a schematic horizontal cross-sectional view of the actuating body of Figure 4
- Figure 8 is a schematic horizontal cross-sectional view of the actuating body of Figure 5
- Figure 9 is a schematic horizontal cross-sectional view of the actuating body of Figure 6.
- axial and radial refer to the longitudinal central axis of the device.
- top”, “bottom”, “vertical” and “horizontal” refer to the upright position of the device shown in Figure 1.
- 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 distribution 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 22 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.
- a hollow insert 60 is advantageously disposed in the dispensing head 20, upstream of said dispensing orifice 21, said hollow insert 60 defining a central expulsion channel 61 and, in cooperation with the bottom wall of the dispensing head 20, a spray profile (not visible in the drawings) directly upstream of said distribution orifice 21.
- 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.
- An actuating body 30 is provided to enable actuation of the device.
- This actuating body 30 is movable relative to the dispensing head 20, said actuating body 30 supporting said reservoir 10 to move it axially relative to the dispensing head 20, in the direction of the distribution orifice 21.
- the actuating body 30 has a bottom wall 32.
- the user presses axially on the actuating body 30, 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 drilling tip 40 and the distribution of the dose of fluid through the distribution orifice 21.
- the reservoir 10 is therefore pushed axially in the direction of the distribution orifice 21, so that the drilling tip 40 will pierce the piston cap 50.
- the contents of the reservoir 10 are then connected to the distribution orifice 21 and the user's support on the actuating body 30 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, WO2021069823, WO2022090675, WO2022101589, WO2022208014.
- the actuating body 30 comprises a radial ring 35 connected to the actuating body by one or more breakable bridges 36.
- This ring 35 cooperates with a part of the distribution head 20, in particular by snapping into a snap housing 25 of the distribution head 20, to form a precompression threshold which the user must overcome during actuation to break the breakable bridges 36 and thus activate the device.
- This radial ring 35 also serves as a first use indicator.
- Figures 2 and 3 show breakable bridges 36 of the state of the art, which are rigid and of constant width by having a square or rectangular shape.
- This well-known type of breakable bridges prevents any relative movement between the parts connected by the breakable bridges, until the application of a predetermined threshold force causing the breakable bridges to break.
- each breakable bridge 36 is elastically deformable up to a breaking point, to absorb the forces exerted on the bridges breakable which are lower than a predetermined threshold corresponding to said breaking point.
- the weight and therefore the inertia of the actuating body 30 and the reservoir 10 on the one hand or of the dispensing head 20 on the other hand are insufficient to reach the breaking point of the breakable bridges 36 in the event of an accidental fall of the device.
- the breakable bridges 36 can deform elastically, in particular elongate, without breaking.
- the present invention therefore ensures safety against unwanted actuation in the event of the device falling.
- each breakable bridge 36 has a contact surface with said radial ring 35 which is greater than the contact surface with said actuating body 30. This guarantees that the breakage of the breakable bridge 36 takes place at the level of the contact surface with the actuating body 30, to ensure reliable sliding of the actuating body 30 in the dispensing head 20 during actuation.
- An advantage of the present invention is that it does not require additional movement or displacement of a part of the device: the user simply takes the device in hand and performs the classic actuation movement. The only difference is that the breakable bridges 36 will only break after their initial elastic deformation, when the breaking point is reached.
- each breakable bridge 36 has at least one curvature which allows an elongation of the breakable bridge 36 by flattening of each curvature.
- the actuating body 30 can move slightly axially by relative to the dispensing head 20. This slight axial movement, corresponding to the elongation of the breakable bridge(s) 36, is less than the stroke necessary for the needle 40 to pierce the piston cap 50. Thus, there is no has no risk of unwanted activation during such an accidental fall.
- each breakable bridge 36 has two curvatures, approximately in the shape of an S.
- each breakable bridge 36 has a curvature, approximately V-shaped.
- each breakable bridge 36 is of frustoconical shape, narrowing towards the actuating body 30.
- each breakable bridge 36 can have a capacity for elongation or expansion. improved stretching compared to a breakable bridge of the state of the art, as shown in Figures 2 and 3.
