Abstract

See full text

A cigarette is provided with the tobacco column portion adjacent the filter assembly encased by a heat shrink material whereby as the burn approaches the butt the heat shrink material begins to contract radially and compress the encased tobacco column restricting the air flow therethrough. This reduces the diameter of burning column adjacent the filter assembly and thus extinguishes or at least confines the remaining tobacco in the cigarette.
