A breath actuated dispenser there-shown has a generally L-shaped hollow body 1 with a mouthpiece 2. An aerosol drug can 3 is mounted in the body. The can has a dispensing spout 4, which engages a receptor moulding 5 incorporating a living hinge 11, a movable outlet member 8 and a kink valve 9. A flap member 31 is pivotally mounted between the can and the receptor moulding. Breathing in through the dispenser by the patient will cause the flap to be drawn down against its spring 34. The outlet member is then tipped down by the spring 37 to point out of the mouthpiece 2, whence the dose is dispensed by opening of the kink valve. |
