Abstract
An inhaler for releasing an aerosol from a container having a lip and an outlet normally sealed by a stem movable relative to the lip. The inhaler has an elongate body comprising a chamber having a first end and a second end, the chamber forming an opening at the first end of the chamber. The elongate body further comprises a stem block with a socket adapted to receive the stem of the container, a dispensing nozzle and a flow restrictive valve. The dispensing nozzle is adjacent to the stem block for providing communication between the socket and the chamber and is adapted to direct a discharge of the aerosol from the container stem into the chamber. The flow restrictive valve is in open communication with the chamber and responsive to a change in fluid pressure. The inhaler also has an actuator pivotably attached to the elongate body. The actuator has an opening adapted to receive the lip of the container and a detent for forming a removable connection between the lip and the actuator. The actuator opening is located substantially directly above the socket.
