Abstract: A fluid product dispenser having a reservoir of fluid product defining a moveable actuating wall, a distribution orifice, and a spring structured to act on the actuating wall to produce a state of maximum volume of the reservoir. The spring co-operates with an arming element structured to cause the spring from an initial state in which the spring does not bias the actuating wall to a state in which the spring biases the actuating wall.

Abstract: A method for operating a dry powder inhaler, the dry powder inhaler having a dose tape having spaced apart doses of a powder pharmaceutical, each dose being in a respective sealed blister. The inhaler includes a breath actuated blister opening system that sequentially opens a blister on the tape. The method involves routing the dose tape between first and second rotating elements; spring biasing the first rotating element to turn in a first direction; holding the first rotating element from rotating against the spring biasing; and releasing the first rotating element, and allowing it to rotate a fraction of one rotation, when air flows adjacent to the first rotating element.

Abstract: A dry powder inhaler, including a housing having an airflow path leading from an inlet, past a powder release location, to a mouthpiece; a drive spool engaged with a capstan adjacent to the powder release location; a spring biasing a ratchet into engagement with the drive spool; and a breath trigger in the airflow path. The breath trigger is moveable from a first position, wherein the breath trigger holds the ratchet, to a second position, wherein the breath trigger releases the ratchet to allow the ratchet to turn the drive spool.

Abstract: A fluid dispenser device including a reservoir containing the fluid and a propellant; a metering valve mounted on the reservoir and including a metering chamber, and a valve member that is movable between a rest position and a dispensing position; and an automatic trigger system, the trigger system including an actuator element to displace one of the valve member and the reservoir relative to the other so as to bring the valve member into its dispensing position. The device also includes a brake system which co-operates with the reservoir or the valve member to slow down displacement of the valve member towards its dispensing position while the device is being actuated, and a valve-member release system that is actuated automatically when the valve member reaches its dispensing position, and which returns the valve member to its rest position independently of the position of the actuator element.

Abstract: A stopper member (C) for mounting on an opening (31) of a fluid reservoir (P), said member being characterized in that it comprises: a base body (1) forming a fluid dispenser orifice (17); an assembly part (20) for mounting in stationary manner on the base body (1); and a closure lid (25) for closing the dispenser orifice (17), the lid (25) being connected to the assembly part via a hinge (26), characterized in that the lid (25) and the part (20) are made as a single piece, the lid (25) initially being connected to the assembly part (20), before the lid is opened for the first time, via at least one bridge (28) of material able to be broken at the first opening.

Abstract: A fluid dispenser device having a body (1), a fluid reservoir (3) containing two half-doses, a dispensing mechanism that dispenses a half-dose of fluid upon actuation, and an energy accumulation mechanism (50, 51, 55) that accumulates energy in the hand of the user and released suddenly so that each of the half-doses is dispensed in full. The dispensing mechanism includes a dispensing member (8) mounted to slide in the reservoir (3) for dispensing the fluid, an actuating element (5) mounted to move between a rest position and an actuating position and on which the user exerts an actuating force to move the dispensing member (8) inside said reservoir (3). The actuating element is mounted to move in a direction substantially transverse to the direction in which the dispensing member (8) moves, and a dose-splitting mechanism (7, 12) dispenses a half-dose of fluid each time the dispensing mechanism is actuated.
