An inhalation device comprising: (i) an inhaler (13) including a housing which comprises a mouthpiece and actuation means to prevent dispensing from the reservoir until a patient is ready to inhale through the mouthpiece, and, (ii) a protective casing (1) surrounding the inhaler, the casing comprising a body portion (2) and a movable cover (3) which may be displaced to allow a patient access to the mouthpiece to use the inhaler, causing relative movement of the inhaler (13) and a biasing means (15) within the protective casing (1) thereby cocking the inhaler ready for use, characterised in that the cover (3) is pivotally attached to said casing (1) and a cocking link (7) is pivotally mounted at one end (8) to the cover and has a portion (9,10) in pivotal engagement with the inhaler or biasing means, whereby opening of the cover causes movement of the cocking link (7) and inhaler (13) relative to the biasing means (15), such that the pivot points (8,17) of the cocking link (7) and the pivot point of the cover to the casing (5) pass through a straight line position to an overcentre position at which the inhaler device is cocked. |
