Patent ID: 8578942

Claim:
An aerosol generator device comprising: an elongate body having a proximal mouth end, a distal end and an interior passageway extending longitudinally to a mouth end, a coupling for releasably coupling to the body a fluid containing pressurised canister having an axial discharge tube that on inward depression is configured to open a valve therein and release the fluid through the discharge tube, with the canister and the passageway having a common longitudinal axis, a trigger mounted on the body and configured to reciprocate along a trigger axis extending transversely of the longitudinal axis, the trigger having a manually depressible surface portion facing outwardly of the body, and a camming surface portion operable on depression of the manually depressible surface portion inwardly of the body along the trigger axis, such that pressing the discharge tube inwardly of the canister operates the valve such that fluid from the canister is released 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 tube of the canister and a trigger engaging end that engages the camming surface portion of the trigger so that said inward depression of the trigger drives the nozzle member towards the distal end of the body member to drive the discharge tube inwardly of the canister to operate the valve and release the fluid through the tube and the nozzle, wherein the trigger comprises a manually depressible button, and the body comprises a generally cylindrical button housing and a generally cylindrical mouth end attached thereto, wherein the button is mounted in the button housing and is configured to reciprocate along the trigger axis, wherein the manually depressible surface portion of the trigger comprises a cylindrical surface generally coaxial with the button housing, and wherein the mouth end includes a filter plug therein.
