Abstract
The present invention relate to a smoking device where heated air forms an aerosol which is conveyed to a user without significant burning or combustion of the aerosol supported substrate.
Claims51
An article for delivering an aerosol to a user, consisting essentially of:
- an open-ended hollow tube having an air passageway between a heat receiving end at one end and a mouth end at an opposed end, said heat receiving end being an open end of said hollow tube;
- said tube being substantially non-combustible upon application of heat to said heat receiving end;
- a substrate containing an aerosol forming component;
- said substrate being positioned within said air passageway and having a distal end;
- said distal end being spaced from said heat receiving end to form a continuous air gap between said heat receiving end and said distal end;
- said continuous air gap having a length of at least two centimeters;
- said continuous air gap preventing combustion of said substrate upon application of said heat to said heat receiving end;
- and,
- said aerosol forming component forming an aerosol upon application of a suction to said mouth end and application of said heat to said heat receiving end.
