Description

The present invention relates to a device for dispensing a fluid product. More specifically, the present invention relates to a unidose device for the nasal dispensing of fluid product to dispense a pharmaceutical fluid product in the nose of a user by way of one single nasal sprays. A drawback of existing devices for nasal dispensing of fluid product is the risk of undesired actuation in the event of a fall of the device. The present invention aims to provide a device for dispensing a fluid product which does not reproduce the above-mentioned drawbacks. More particularly, an object of the present invention is to provide a device for dispensing a fluid product that avoids any risk of undesired actuation, for example in the event of a fall of the device. Another object of the present invention is to provide such a device in which the risk of undesired actuation in the event of a fall is minimal or even zero. Another object of the present invention is to provide such a device that is simple and inexpensive to manufacture and to assemble. The present invention thus provides a device for dispensing a fluid product comprising a reservoir containing fluid product and a dispensing head that is provided with a dispensing orifice and a radial flange that forms a finger rest during actuation, said reservoir being axially movable relative to said dispensing head during actuation, a stopper/piston being movable in said reservoir so as to dispense fluid product through said dispensing orifice during actuation, said device comprising a blocking member that blocks the axial movement of said reservoir in said dispensing head, said blocking member being movable and/or deformable between a blocking position and a release position, said device comprising fins arranged on or above said radial flange, said fins being movable between a rest position, in which said blocking member is in the blocking position, and a pressing position, in which said blocking member is moved and/or deformed into the release position, said blocking member being assembled around an actuation body receiving said reservoir, under said radial flange. Advantageously, said reservoir is formed by a body that is hollow and blind, comprising a bottom and a single opening which, in the rest position, is sealed by said stopper/piston. Advantageously, the device comprises a hollow insert inserted and fixed in said dispensing head, said insert supporting a piercing tip to pierce said stopper/piston and thus connect said reservoir to said dispensing orifice during actuation. Advantageously, said piercing tip is made separately and then assembled in said insert, in particular by force-fitting or by overmoulding. In an advantageous variant, said piercing tip is moulded integrally with said insert. Advantageously, said blocking member comprises a plate provided with a hole through which said actuation body extends, said hole defining an edge that engages in a blocking position with a groove of said actuation body, the diameter of said hole being greater than the external diameter of said actuation body, said plate being radially movable between a blocking position, in which said edge is arranged in said groove, and a release position, in which said plate is laterally offset, such that said actuation body can slide axially in said hole. Advantageously, said radial flange of said dispensing head includes at least one fin extending axially upwards at rest and deformable downwards by the user. Advantageously, said plate includes an axial projection that extends axially upwards, and said at least one fin includes on its lower surface a lug adapted to engage with said axial projection so that when the user presses on said fin, said lug pushes said axial projection laterally, which will move said plate from its blocking position towards its release position. Advantageously, the device comprises two diametrically opposed fins. Advantageously, the device includes an actuation body receiving said reservoir, said actuation body including a radial disk connected to said actuation body by one or more breakable bridges, said radial disk engaging with a portion of said dispensing head so as to form a precompression threshold that the user must overcome during actuation so as to break said breakable bridges and thus actuate the device. Advantageously, said reservoir contains one single dose of fluid product dispensed in one single actuation.
