Abstract

The present invention relates to an inhalation apparatus for dispensing substances for inhalation and, in particular, but not exclusively, for dispensing medicinal products in aerosol form from a pressurised dispensing container. An inhalation apparatus (1) is provided for dispensing a product comprising housing (20) adapted to receive a pressurised dispensing container (10) and a mouthpiece (22). The apparatus also comprises a duct for conveying, in use, product from the container to the mouthpiece, a sliding seal member (44, 45) movable under action of triggering means (60) between a first position in which the duct is closed and a second position in which the duct is open, wherein a spring means (50) is provided to bias the sliding seal member towards the second position. At least one air inlet (25) is provided for allowing air into the housing and a flow sensor (70) is activatable, by means of an airflow created when a user applies suction to the mouthpiece to activate said triggering means such that said sealing member is moved by said spring means into its second position to allow product to be dispensed into the airflow.
