Embodiment Construction

[0028] The present invention is applicable to various types of inhalers that are activated by the user's inhalation (BAI), and although the description of the embodiment will be in connection with an inhaler whose inhalation activation system acts on the valve of the valve, it is clear that the present invention The invention is also applicable to devices where the spring acts on the reservoir. Whether the spring force of the valve is exerted on the valve or on the reservoir has no direct effect on the invention in both cases, the purpose of which is to slow down the movement of the valve towards its dispensing position.

[0029] Accordingly, the following description refers to a device disclosed in document WO 99 / 44662, which document is hereby incorporated by reference in relation to the operation of an inhalation activation system of a fluid dispensing device.

[0030] According to the invention, a braking device is proposed acting on the valve of the valve and on the part ...

Abstract

A fluid dispenser device comprising: a reservoir ( 1 ) containing the fluid and a propellant; a metering valve ( 2 ) mounted on said reservoir and comprising a metering chamber, and a valve member ( 3 ) that is movable between a rest position and a dispensing position; and an automatic trigger system, preferably actuated by the user inhaling in order to actuate said valve, said trigger system including an actuator element ( 10 ) adapted to displace one of the valve member ( 3 ) and the reservoir ( 1 ) relative to the other so as to bring the valve member ( 3 ) of the valve ( 2 ) into its dispensing position, the device being characterized in that it includes, in combination, a brake system ( 60, 70 ) which co-operates with the reservoir ( 1 ) or with the valve member ( 3 ) in order to slow down displacement of the valve member ( 3 ) towards its dispensing position while the device is being actuated, and a valve-member release system that is actuated automatically when the valve member ( 3 ) reaches its dispensing position, and which returns said valve member ( 3 ) to its rest position independently of the position of said actuator element ( 10 ).

Description

technical field [0001] The invention relates to a fluid dispensing device, in particular an inhalation device having a dosing valve of the MDI (Metered Dose Inhaler) type, wherein the actuation of the dosing valve is controlled by inhalation by the user. Background technique [0002] This type of inhaler activated by inhalation is generally called BAI (Breath Activated Inhaler), which uses a dosing valve (MDI) system, and such inhalers are generally based on an activation member with a spring , when the user inhales, the spring is released by a suitable device. The loading or compression of the spring is generally achieved by driving a lever, such as when the lid of the oral connector of the inhaler is opened. When inhaling, the force of the spring is opposite to the dose valve or reservoir of the inhaler, so that the dose valve can be driven, so that the valve The valve moves relative to the reservoir. This keeps the valve valve and parts of the reservoir that are not und...
