Abstract
Inhalation apparatus for dispensing a product comprises a housing (2) having a cylindrical portion (6) adapted to receive a pressurized dispensing container (3) and a mouthpiece (7). The apparatus includes a duct (18) communicating with the container receiving portion for conveyance of product towards the mouthpiece. An air inlet valve provided by a vent hole (14) and an actuator (19) is provided and is biased with a first position sealing the air inlet. The actuator is manually movable to a second position in which the air inlet is unsealed and allows air to flow into the housing and through the mouthpiece for any user applied suction to the mouthpiece and to a third position for the dispensing of a product into the resulting air flow. The movement between the second and third positions delays the discharge of the product until air flow through the device has been established.
