Abstract
A valved-container inhaler (150) has a mechanical return assembly with a spring (214) and a transfer (212) configured to transfer stored potential energy from the spring to a canister (51) and a clutch (208, 210) in a load path of the force between the spring and the transfer, the clutch being rotatable between a first condition in which load is transferred from the spring to the transfer, and a second condition in which the spring and the transfer can move relative to one another to interrupt the load path and thereby allow the canister to resile after actuation.
Claims20
A mechanical return assembly for a valved-container inhaler comprising:
- a resilient structure;
- a transfer configured to transfer stored potential energy from the resilient structure to a resilient, valved container in the form of a force to thereby release a medicament therefrom;
- a clutch in a load path of the force between the resilient structure and the transfer, the clutch having a first part and a second part, in which rotation of the second part relative to the first part moves the clutch between:
- a first condition in which load is transferred from the resilient structure to the transfer, and
- a second condition in which the resilient structure and the transfer can move relative to one another to interrupt the load path and disconnect the valved canister from the force and thereby allow the valved container to resile after actuation.
