Abstract
An inhaler 10 for delivery of a medicament by inhalation. The inhaler 10 has a drive mechanism, a canister drive 22 for receiving a canister 50 of medicament, a spring 20, and a trigger mechanism with a latch 35. The latch 35 has a locked position to prevent linear movement of the canister drive 22 and holds the spring 20 in a loaded configuration; and an unlocked position in which the latch 35 is disengaged from the canister drive 22. The trigger mechanism comprises a blocker 32. The blocker 32 has a blocking position in which it contacts the latch 35 to block movement from the locked position to the unlocked position; and a rotated position in which the blocker 32 is disengaged from the latch 35 to allow it to lock and unlock.
