A medicated inhalant dispenser (1) has a plastics material body (2) having a mouthpiece (3). A pressurised, inhalant source (4) has a canister (5) and a spout (6), which is moved towards the canister for release of a dose from the canister. The spout is accommodated in a junction member (7), which is movable by a cam (8) connected to a pivotal cover (9) for the mouthpiece. Opening of the cover sets a breath actuable kink valve (10), having a nozzle (11) through which the inhalant is released and a breath flap (12) actuation. Opening also causes the junction member to be lifted for dose dispensing into the kink valve. Breathing in releases the dose for inhalation. A closed sleeve (20) is provided for abutment of the end (21) of the canister as the junction member is moved towards the canister. Between the canister end (21) and an end (22) of the closed sleeve, an adjustable abutment (23) is provided. The closed sleeve is welded onto the body. The abutment or end location (23) is sized to provide that the source is supported in its correct position for opening of its valve on operation of the cam mechanism (8). |
