An adaptor for use with a container equipped with a dispensing valve that comprises a valve stem movable between an inner closed or priming position and an outer dispensing position, for dispensing doses of pressurized aerosol formulation as well as dispensers comprising such an adaptor and container; said adaptor being adapted to receive the container and comprising an actuation mechanism, said actuation mechanism being arranged such that the user will operate the mechanism by applying a depressive or squeezing force and the dose will be dispensed upon said depressive or squeezing force and said actuation mechanism being arranged such that upon release of the mechanism by the user, the valve stem of the dispensing valve will be moved automatically into its inner closed or priming position.

Cette invention concerne un adaptateur destiné à être utilisé avec un récipient équipé d'une valve de distribution qui comporte une tige de manoeuvre pouvant passer d'une position d'amorçage ou fermée interne à une position de diffusion externe et servant à diffuser des doses de formulations en aérosol sous pression. Cette invention concerne également des diffuseurs comprenant cet adaptateur ainsi qu'un récipient. L'adaptateur est conçu pour recevoir le récipient et comporte un mécanisme d'actionnement, lequel mécanisme d'actionnement est conçu de sorte que l'utilisateur puisse actionner le mécanisme par l'application d'une dépression ou d'une pression, la dose étant ainsi diffusée sous l'effet de la dépression ou de la pression. Ce mécanisme d'actionnement est également conçu de sorte que lorsque l'utilisateur relâche ledit mécanisme, la tige de manoeuvre de la valve de distribution passe automatiquement dans sa position d'amorçage ou fermée interne.
