Abstract
An improved, cleaner functioning smoking article is provided, comprising a aerosol forming substrate engineered to include airflow channels. Features include a hollow tube, which may be comprised of various materials, including the material for vaporization itself, within the engineered material, such as tobacco, for efficient vaporization. Other features include a hollow, inverted cone to permit air ingress in a closed bottomed HNB cigarette, and a capsule cigarette designed to retain loose leaf and original material for clean vaporization.
Claims35
An aerosol forming substrate for a smoking article comprising at least one air channel which runs substantially through the aerosol forming substrate, wherein the aerosol forming substrate is comprised of least one sheet of reconstituted tobacco rolled to form a substantially cylindrical tube which is disposed substantially longitudinally through the aerosol forming substrate.

A method of constructing a heat not burn cigarette comprising:
- Attaching a porous filter at each end of a solid filter;
- Attaching a hollow tobacco rod to the exposed end of each porous filter;
- Attaching a hollow tube to the exposed end of each hollow tobacco rod to form a longitudinally disposed first assembly;
- Wrapping the length of the first assembly in a covering wrap (tipping paper);
- Perforating the covering wrap circumferentially on the side surface at each end;
- Severing the first assembly in the middle;
- Rotating the two halves 180 degrees in opposite directions;
- Inserting a filter section, at least one hollow filter section, and two hollow cones to form a second assembly;
- Wrapping the second assembly in a covering wrap;
- Severing the second assembly in the middle, thereby forming two cigarettes.
