Reduced ignition propensity smoking article

A wrapper for surrounding a tobacco column to create a smoking article having reduced ignition propensity, the wrapper having a base permeability and comprising:

• an untreated area and
• a least one discrete area treated with a composition to reduce the base permeability so that as a coal of a burning tobacco firecone advances by the treated area, the smoking article self-extinguishes if placed on a surface, the composition comprising:
• a permeability reducing substance,
• a burn rate retarding substance and
• a burn rate accelerating substance.

A smoking article having reduced ignition propensity comprising:

• a tobacco column;
• a wrapper surrounding said tobacco column, said wrapper comprising:
• a base permeability,
• untreated area and
• a least one discrete area treated with a composition to reduce said base permeability so that as a coal of a burning tobacco firecone advances by said at least one treated area, the smoking article self-extinguishes, said composition comprising:
• a permeability reducing substance,
• a burn rate retarding substance and
• a burn rate accelerating substance,
• wherein at least one of said burn rate retarding substance and said burn rate accelerating substance is further an organoleptic enhancing substance that substantially reduces any difference in a smoker's experience between the smoking of said at least one treated area and said untreated area during of the smoking article;
• and
• a filter element.

A method for making a smoking article having reduced ignition propensity comprising:

• treating a plurality of discrete areas of paper having a base permeability with an aqueous composition, drying the discrete areas such that the discrete areas have a reduced permeability and include a burn rate retarding substance and a burn rate accelerating substance, thereby forming a wrapper;
• surrounding a tobacco column with at least a portion of the wrapper so that at least one discretely treated area is found between the ends of the wrapper-surrounded tobacco column so that as a coal of a burning tobacco firecone advances by said at least one treated area, the smoking article self-extinguishes if left on a surface;
• and
• adding a filter element to at least one end of the wrapper surrounded tobacco column, wherein at least one of said burn rate retarding substance and said burn rate accelerating substance is further an organoleptic enhancing substance that substantially reduces any difference in a smoker's experience between the smoking of said at least one treated area and said untreated area during of the smoking article.

A population of smoking articles having a reduced ignition propensity comprising:

• a plurality of smoking articles, each smoking article comprising
• a tobacco column,
• a wrapper surrounding said tobacco column so that the smoking article includes an ignition end and a distal end, and
• at least one banded region between the ignition end and the distal end having a combustion characteristic substantially different from that of an unbanded region;
• and
• a distance from the ignition end to the at least one band of each smoking article being at least one of random, quasi-random and sequentially related within the population.

A population of smoking articles having a reduced ignition propensity comprising:

• a plurality of smoking articles, each smoking article comprising
• a tobacco column,
• a wrapper surrounding said tobacco column so that the smoking article includes an ignition end and a distal end, and
• at least two spaced apart banded regions between the ignition end and the distal end having a combustion characteristic substantially different from that of an unbanded region;
• and
• a distance from the ignition end to at least one of the banded regions of each smoking article being at least one of random, quasi-random and sequentially related within the population.

A package of smoking articles having a reduced ignition propensity comprising:

• a package;
• twenty smoking articles within said package, each smoking article comprising
• a tobacco column,
• a wrapper surrounding said tobacco column so that the smoking article includes an ignition end and a distal end, and
• at least two spaced apart banded regions between the ignition end and the distal end having a combustion characteristic substantially different from that of an unbanded region;
• and
• a distance from the ignition end to at least one of the banded regions of each smoking article being at least one of random, quasi-random and sequentially related within the package.

A grab sample of smoking articles having a reduced ignition propensity comprising:

• a plurality of smoking articles, each smoking article comprising
• a tobacco column,
• a wrapper surrounding said tobacco column so that the smoking article includes an ignition end and a distal end, and
• at least two spaced apart banded regions between the ignition end and the distal end having a combustion characteristic substantially different from that of an unbanded region;
• and
• a distance from the ignition end to at least one of the banded regions of each smoking article being at least one of random, quasi-random and sequentially related within the grab sample.

A cigarette paper for use in making a cigarette having reduced ignition propensity comprising:

• a fibrous paper having a base permeability, an untreated area and a treated area, the treated area being treated with a composition to reduce the base permeability so that when the paper is made in to a cigarette that is smoked, as a coal of a burning tobacco firecone advances by the treated area, the cigarette self-extinguishes if placed on a surface, the composition comprising:
• a permeability reducing substance present in sufficient quantity to effect the self-extinction;
• and
• a burn rate accelerating substance present in sufficient quantity to cause a smoker's organoleptic experience to be substantially indistinguishable from the organoleptic experience of smoking the untreated area of the cigarette.
