Abstract:
An inhaler apparatus for dispensing a product comprising a housing having a portion adapted to receive a pressurized dispensing container of a product and a mouthpiece, said apparatus further comprising a duct communicating with the container, said duct having an outlet defining the direction of flow of the product towards the mouthpiece, an air inlet valve having an air inlet for allowing air into said housing and an airflow controller biased to seal said air inlet, said airflow controller being manually movable to unseal said air inlet to allow air to flow into said housing when a user applies suction to said mouthpiece, a passage which directs the airflow to a location adjacent said outlet of said duct, the positioning of said passage relative to said duct outlet and said mouthpiece being such that a component of the initial air flow direction is away from said mouthpiece and opposes the product flow before the air flows towards the mouthpiece.
