<p>This invention is an inhaler apparatus (10) having a housing (12) with a first wall (14), a second wall (16), defining an air inlet (18), and an air outlet (20). The first and second walls define an internal housing volume (13), having portions which are movable relative to each other so as to expand the internal housing volume from a non-inhalation state, wherein the internal housing volume has a first volume, to an inhalation state, wherein the internal housing volume has a second volume, the second volume being larger relative to the first volume. An airflow chamber (68) is defined within the housing between the air inlet, and the air outlet when the housing is in the inhalation state. A medicament (62) is contained between the first and second walls, which is exposed to airflow within the airflow chamber when the housing is in the inhalation state.</p> |
