PROBLEM TO BE SOLVED: To provide a compact inhaler that can be switched from an inhalation status to an inhalation standby status and vice versa with ease. SOLUTION: In an inhalation standby status, an airflow duct forming member 4 for forming an airflow duct on an inhaler body 2 having an ejection head 1 is driven to slide so as to be placed at rest on the inhaler body 2 to partly cover the top part of the latter 2 by means of a slide mechanism 8 and make the airflow duct disappear. At this time, the top wall of the airflow duct forming member 4 covers the ejection head 1 to be worked as a cap shielding it from external air. In an inhalation status, the airflow duct forming member 4 is driven to slide up and produce an airflow duct on the inhaler body 2. COPYRIGHT: (C)2010,JPO&INPIT |
