Abstract
An inhaler for powdered medicament in capsules has a swirling chamber which can be opened to allow access of a closed capsule into the swirling chamber for operation of capsule-opening means in the swirling chamber. Access to the swirling chamber is gained by a pivoting cover member (22) which is provided with interlock means associated with the capsule-opening means to ensure that the capsule opening means cannot be operated while the cover member is in its open position to allow access of the user's finger to the region (28) of the swirling chamber (26,28) where the capsule-opening pins (30) could damage the user's finger. A further embodiment of an inhaler has a removable capsule reservoir having a container portion (74) with a closure (76) removable to reveal the interior of said reservoir and closable to define one entire side face of said reservoir, the closure member (76) being hinged to the container portion at thin film hinge (78). The capsule container is closed by a sliding cover (16) held to the container (74) for sliding movement along a second face of the closure reservoir opposite said first face defined by the closure (76).
