Abstract:
Dispensing device for a fluid product activated by inhaling, which comprises a product reservoir (20) containing a propellant gas, a pump or dosing valve (30) to selectively dispense the product through a dispensing orifice (9), and an activating device controlled by inhaling, said activating device comprising:a control element (3) mobile between an inoperative position in which it blocks the dispensing orifice (9) and a control position, said control element (3) being displaced by a user, an actuating member (7), mobile between a non-actuating position, in which the pump or dosing valve (30) is not actuated and an actuating position in which the pump or dosing valve (30) is actuated, said actuating member (7) being urged towards its actuating position when the control element (3) is in its control position, a retaining element (8), mobile between a retaining position in which it cooperates with the actuating member (7) to retain it in its non-actuating position and a releasing position, in which said actuating member (7) moves into its actuating position, and a cam element (2), mobile between a storing position in which said retaining element (8) is locked in its retaining position, and an inhaling position, in which said retaining element moves into its releasing position, said cam element (2) being urged towards its storing position and being moved into its inhaling position when the user of the device inhales, characterized in that the retaining element (8) is elastically deformable between its retaining position and its releasing position, the retaining element (8) being urged towards its releasing position by the actuating member (7) when the control element (3) is in its control position.
