[Figure 6] FIG. 6 is a schematic cross-sectional view of the device shown in FIG. 5. [Figure 7] FIG. 2 is an exploded perspective view of the device shown in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0020] In the following description, the terms "axial" and "radial" refer to directions relative to the central longitudinal axis A of the device. The terms "upper" and "lower" refer to positions relative to the upright position of the device shown in each figure. Each figure shows a preferred embodiment of the invention.

[0021] In this embodiment, the device is a single dose device, ie the container contains one dose of the fluid product that is dispensed with one actuation.

[0022] In this embodiment, a container 10 containing the fluid product to be dispensed (usually a liquid) is disposed within a body forming a dispensing head 20 .

[0023] The dispensing head 20 comprises an axially oriented outlet 21 which serves to expel a dose of fluid from the dispensing head 20 while the device is activated by a user.

[0024] Discharge head 20 comprises an elongated nosepiece with a discharge port 21 at its proximal axial end and a lateral body 24 connected to the nosepiece by a radial flange 23 .

[0025] In the advantageous embodiment depicted in the drawings, a hollow insert 60 is positioned within the dispensing head 20 upstream of the discharge orifice 21. The hollow insert 60 defines a central discharge channel 61 and engages the bottom wall of the dispensing head 20 to form a spray profile (not visible in the drawings) immediately upstream of the discharge orifice 21.

[0026] The central discharge channel 61 terminates at its lower end in a perforating tip 40, which may be integrally molded with the insert 60. Alternatively, the tip may be fabricated separately, such as from a different metal or synthetic material, and then assembled into the insert by, for example, press-fitting or overmolding. The perforating tip 40 extends axially downward beyond the elongated cylindrical body of the insert 60.

[0027] The container 10 is advantageously formed by a blind cavity with a single opening defining a neck 11 , said opening being closed by a stopper / piston 50 .

[0028] In the single dose illustrated example, the container 10 contains one dose of the fluid product to be dispensed with one actuation of the device.

[0029] The stopper / piston 50 is movable within the container 10 between a rest position and an actuated position and, during actuation, causes the fluid product to be dispensed through the outlet 21 .

[0030] Advantageously, actuation means 30 are provided to enable the device to be actuated.

[0031] In the embodiment shown in Figure 1, the actuating means 30 comprises an actuating body 31 movable relative to the discharge head 20, which engages with the container 10 to move the container 10 axially relative to the discharge head 20 towards the discharge outlet 21.

[0032] To activate the device, the user pushes up on the bottom wall 32 of the actuator 31, causing the actuator 31, together with the container 10, to move axially within the dispensing head 20. This causes the piercing tip 40 to pierce the stopper / piston 50 and expel a dose of fluid through the discharge opening 21. In configurations where the actuator 31 is not provided, the user can press directly on the bottom of the container 10.

[0033] Thus, during operation of the device, the container 10 is pushed axially towards the outlet 21 so that the piercing tip 40 pierces the stopper / piston 50 .

[0034] In this way, the contents of the container 10 are connected to the outlet 21, and when the user applies pressure to the actuator 31, the stopper 50 moves within the container 10, causing the fluid product in the container 10 to be dispensed.

[0035] It should be noted that the present invention can also be applied to devices that do not have a perforation tip suitable for perforating a stopper / piston, as described in, for example, Patent Documents 1 to 5.

[0036] Advantageously, the effector 31 comprises a radial disc 35 connected to it by one or more breakable bridges 36, as particularly shown in FIG.

[0037] The disk 35 engages a portion of the dispensing head 20 and forms a pre-compression threshold that the user must overcome during actuation to break the breakable bridge 36 and activate the device.

[0038] These breakable bridges 36 provide safety against unwanted actuation, however, if the device is dropped axially, the safety provided by the breakable bridges 36 may not be sufficient if the inertia of the device is sufficient to break the breakable bridges.

[0039] According to the invention, the device comprises a blocking member 200 that blocks axial movement of the container 10 within the dispensing head 20. The blocking member 200 is movable and / or deformable between a blocking position and a release position.

[0040] The user must first move and / or deform the blocking member 200 to the release position, after which the container 10 can be moved axially within the dispensing head 20 to activate the device.

[0041] According to the invention, the device comprises fins 210 located on or above the radial flange 23, which are movable between a rest position when the blocking member 200 is in the blocking position and a pressing position when the blocking member 200 has been moved and / or deformed into the release position.

[0042] Advantageously, the present invention provides that movement and / or deformation of the blocking member 200 to the release position is achieved by the user taking the device in their hand and pressing their fingers against the radial flange 23 of the dispensing head 20 .

[0043] The invention thus makes it possible to ensure safety in case of a device being dropped, without requiring any additional action from the user to activate the device.

[0044] The user picks up the device, places two fingers on the two fins 210 located on or above the radial flange 23 of the dispensing head 20 and presses the distal axial bottom wall 32 of the actuation body 31 with their thumb.

[0045] When the pushing action is performed to activate the device, first the fin 210 is moved by the finger towards the pressing position, which moves and / or deforms the blocking member 200 towards the release position, and then the actuator 31 is moved by the thumb to expel a dose.

[0046] According to the invention, the blocking member 200 is assembled around the effector body 31 below the radial flange 23 .

[0047] The blocking member 200 comprises a plate 201 having a hole 202 formed therein, through which the actuator 31 extends.

[0048] The bore 202 defines a lip 205 that engages the groove 38 of the actuating body 31 in a blocking position. The diameter of the bore 202 is larger than the outer diameter of the actuating body 31, and the plate 201 is radially movable between a blocking position in which the lip 205 fits into the groove 38 and a release position in which the plate 201 is laterally offset to allow the actuating body 31 to slide axially within the bore 202.

[0049] The plate 201 is provided with an axial protrusion 203 that extends axially upward.

[0050] In this embodiment, the radial flange 23 of the dispensing head 20 is provided with at least one fin 210 which, when at rest, extends axially upward relative to the radial plane formed by the radial flange 23 and is deformable downward by the user.

[0051] Advantageously, this deformation is elastic, with the fins 210 being subjected to a restoring force towards their rest position and being deformed towards their pressed position.

[0052] The underside of the fin 210 is provided with a lug 211 adapted to engage with the axial projection 203 of the plate 201 .

[0053] Thus, when the user presses the fin 210, the lug 211 of the fin 210 pushes the axial protrusion 203 of the plate 201 laterally to the left, causing the plate 201 to move from the blocking position towards the release position, as shown in Figures 2 and 4. The device can then be actuated by pressing axially on the bottom wall 32 of the actuating body 31.

[0054] Advantageously, two diametrically opposed fins 210 are positioned on either side of the dispensing head 20 .

[0055] An advantage of the present invention is that no additional movement or displacement of parts of the device is required.

[0056] A user would typically pick up the device and place their thumb on the bottom wall 32 of the actuation body 31 and their fingers on the fins 210 located on the radial flange 23 of the dispensing head 20. By performing a typical actuation gesture, they would first move the fins 210 to release the blocking member 200 from blocking the movement of the container 10, and then actuate the device.

[0057] Of course, other variations are possible without departing from the scope of the invention as defined by the appended claims.
