Abstract
A cigarette including a tube of tobacco having a circumferential wall fabricated of a tobacco material with ridges and grooves from in the circumferential wall extending longitudinally of the tobacco tube, a wrapper of combustible material circumscribing the outside peripheral surface, and a filter rod attached at one end of the tobacco tube. Also, a method of making a cigarette includes forming a sheet of tobacco material, forming corrugations in the sheet of tobacco material and forming the corrugated sheet into a cylindrical tube.
Claims8
A cigarette comprising:
- a tube of tobacco material having a circumferential wall fabricated of a tobacco material formed with longitudinally extending grooves and ridges in its outside peripheral surface and longitudinally extending grooves and ridges formed in its inside peripheral surface;
- a wrapper of combustible material circumscribing the outside peripheral surface of the tobacco tube in contact with the ridges of the tobacco tube;
- a smoke filter rod coaxially located with the tobacco tube at one end thereof;
- and,
- tipping material circumferentially overlapping the wrapped tobacco tube at the end thereof adjacent the filter rod.
A method of making a cigarette comprising the steps of:
- forming a sheet of tobacco material;
- forming corrugations in the sheet of tobacco;
- folding the corrugated sheet of tobacco material into a generally cylindrical tube;
- wrapping a first sheet of combustible material circumferentially around the outside peripheral surface of the tobacco tube in contact with the ridges of the corrugations;
- locating a smoke filter rod coaxially with the tobacco tube at one end thereof;
- and,
- folding a tipping material circumferentially overlapping the wrapped tube of tobacco at the end of the tube of tobacco adjacent the filter end.
A method of making a cigarette comprising the steps of:
- forming a sheet of tobacco material;
- forming corrugations in the sheet of tobacco;
- overlaying one corrugated surface of the corrugated sheet with a first sheet of combustible material in contact with the ridges of the corrugations;
- folding the corrugated sheet into a cylindrical tube with the first sheet of combustible material located on the outside peripheral surface of the resulting cylindrical tube;
- locating a smoke filter rod coaxially with the tobacco tube at one end thereof;
- and,
- folding a tipping material circumferentially around the filter rod and circumferentially overlapping the wrapped tube of tobacco at the end of the tube of tobacco adjacent the filter rod.
