Patent ID: 8689786

Claim:
An aerosol generator device for delivering aerosol to the mouth of a user, comprising: an elongate body having a proximal mouth end, a distal end, a longitudinal exterior surface extending between the proximal and distal ends, and an interior passageway extending longitudinally to the mouth end; a coupling to releasably couple a fluid containing pressurised canister to the body, the canister having an axial discharge tube that on inward depression opens a valve therein and releases the fluid through the discharge tube, with the canister and the passageway having a common longitudinal axis; a trigger rotatably mounted on the body about a trigger axis within the body that is spaced from and extending transversely of the longitudinal axis, the trigger having a manually depressible surface portion facing outwardly of the body the manually depressible surface portion being configured to be pressed inwardly of the body such that the trigger rotates inwardly towards the longitudinal axis of the body, the manually depressible surface portion being generally coextensive with the exterior surface of the body, and the trigger further including a camming surface portion configured to cause the discharge tube to be pressed inwardly of the canister on depression of the surface portion inwardly of the body, and operate the valve that releases the fluid from the canister through the discharge tube and through the body to the mouth end; and a tubular nozzle member slidably mounted in the body, the nozzle member having an end to abut the discharge tube of the canister and a trigger engaging end that engages the camming surface portion of the trigger, said inward depression of the trigger configured to drive the nozzle member towards the distal end of the body and the discharge tube inwardly of the canister to operate the valve and release the fluid through the discharge tube and the nozzle to provide an aerosol.
