Abstract
An inhaler for delivering medicament by inhalation, comprising a housing for holding a canister of medicament having a body and a valve stem compressible together to actuate the canister to deliver a dose of medicament from the valve stem, an actuation mechanism for compressing the canister, a cannister re-set mechanism comprising a locking element for locking the canister in a compressed state and a release member resiliently biassed by the actuation mechanism on compression of the canister to release the locking mechanism to allow reset of the canister. By provision of the locking element for locking the canister in a compressed state, it is possible to ensure re-set does not occur immediately. The release member subsequently releases the locking mechanism to allow re-set of the canister after a proper dose has been delivered. The cannister reset mechanism further comprises a damping element for damping movement of the release member to delay the action of the resilient biassing to release the locking element a predetermined period of time after actuation of the canister.
