    Abstract: An inhalation type medication delivery device includes a dispenser body having a powder containment chamber at one axial side thereof and an inhalation port for drawing in a powder type medication on the another. An attached lid is provided on the dispenser body for opening and/or closing the powder containment chamber. In addition, an air passage is defined in the body allowing a powder type medication to be introduced into an airflow toward the inhalation port according to inhalation by a user. One end of the air passage opens through the lid towards the outside atmosphere and the other end communicates with the inhalation port while passing through the powder containment chamber. Also, a check valve is installed in the lid to prevent air drawn into said inhalation port from flowing in an outward direction opposite a medication delivery direction toward the inhalation port.
