Abstract (en)
[origin: GB2323040A] The apparatus comprises a housing (2) for a pressurised dispensing container (3) and including a portion (8) adapted to receive a valve stem (9) of the pressurised dispensing container, an air inlet to said housing and a mouthpiece (7), duct means communicating with the housing for conveyance of product towards the mouthpiece, and an air flow controller in the form of an annular membrane (12) adjacent to the valve stem receiving portion. The air flow controller (12) is biased to a first position corresponding to no or a minimum flow of air from the air inlet to the mouthpiece, and is movable in use by the pressurised dispensing container to a second position corresponding to a maximum flow of air from the air inlet to the mouthpiece, continued movement of the container causing a dose of product to be dispensed into the maximum air flow, the air flow being created by a user applying suction to the mouthpiece.
