March 1, 2014

By a News Reporter-Staff News Editor at Investment Weekly News -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor Schennum, Steven Michael (Plainfield, IL), filed on October 8, 2013, was made available online on February 13, 2014.

The assignee for this patent application is British American Tobacco (Investments) Limited.

Reporters obtained the following quote from the background information supplied by the inventors: "A nicotine dispensing aerosol device is disclosed in U.S. Pat. No. 4,945,929, which simulates a smoking article such as a cigarette, without having to burn tobacco."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "The invention provides an improved aerosol generator device that can be operated manually by a consumer to deliver aerosol, for example to their mouth.

"An embodiment of the invention provides an aerosol generator device that includes an elongate body having a proximal mouth end, a distal end and an interior passageway extending longitudinally to the mouth end. A coupling to the body is configured for releasably coupling a fluid containing pressurised canister having an axial discharge tube depressible inwardly to open a valve therein to release the fluid through the discharge tube, with the canister and the passageway having a common longitudinal axis. A trigger is mounted on the body 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, to press the discharge tube inwardly of the canister and operate the valve so as to release fluid from the canister through the discharge tube and through the body to the mouth end.

"A tubular nozzle member may be 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.

"The body may have a generally tubular sidewall, the interior passageway extending from the distal end to the mouth end, and a trigger chamber extending outwardly from the interior passageway into the sidewall, the trigger being slidably mounted in the trigger chamber for reciprocal movement along the trigger axis, with the depressible surface portion of the trigger being disposed adjacent the exterior surface of the body member.

"The coupling may include a sleeve adapted to grip the canister at one end and releaseably attached to the distal end of the body at the other end.

"The trigger may comprise a manually depressible button, and the body can comprise a generally cylindrical button housing and a generally cylindrical mouth end attached thereto, the button being mounted in the button housing to reciprocate along the trigger axis.

"The manually depressible surface portion of the trigger may comprise a cylindrical surface generally coaxial with the button housing. The mouth end may include a filter plug.

"The nozzle may include one or more radially extending lugs and the trigger may include one or more depending flanges with an inclined edge that engages a respective lug to provide the camming surface portion.

"The canister may be generally cylindrical, with a valve configured to release a metered dose of fluid.

"In order that the invention may be more fully understood, embodiments thereof will now be described by way of illustrative example with reference to the accompanying drawings in which:


"FIG. 1 is side view of an aerosol generator device;

"FIG. 2 is a perspective view the aerosol generator device of FIG. 1;

"FIG. 3 is an exploded view of the device shown in FIGS. 1 and 2;

"FIG. 4a is a partial sectional view of the device shown FIGS. 1 to 3 in a rest configuration

"FIG. 4b corresponds to FIG. 4a with the device in an operative, discharge configuration;

"FIGS. 5a and 5b are partial side views showing interior features of the device in the rest and operative discharge configurations respectively;

"FIGS. 6a and 6b are sectional views along the line Y-Y' of FIG. 5 in the rest and operative discharge configurations respectively;

"FIGS. 7a and 7b are partial sectional views showing interior features of the device in the rest and operative discharge configurations respectively;

"FIG. 8 is a perspective view from one end of a coupling sleeve for attaching a canister to the body of the device;

"FIG. 9 is a perspective view of the nozzle member of the device; and

"FIG. 10 is a sectional view of the nozzle member."
