ABSTRACT:
A lightweight cylindrical body is provided constructed of heat resistant and medium heat conducting material such as tetrafluoroethylene and the body is slightly longer than a companion cigarette having the ignited end thereof frictionally telescoped into one end of the body to a position with the ignited end spaced inward of the second end of the tubular body and the end of the cigarette remote from the ignited end projecting outward of the aforementioned one end of the tubular body. The second end of the tubular body includes radial bores spaced circumferentially thereabout and longitudinally therealong. The ignited end of the cigarette is spaced inward of the radial bores and the tubular body serves to restrict the free flow of combustion supporting air to the ignited end of the cigarette when a smoker is not drawing upon the cigarette and also to conduct, at a medium rate, the heat of combustion of the ignited end of the cigarette through the walls of the tubular body to the external surfaces thereof for dissipation in the ambient air. The heat conducting capacity of the tubular body is not so great as to conduct the heat of combustion of the cigarette through the walls of the body at a rate sufficient to cause the external surfaces of the body to become heated to an extent which might cause burns to a smoker handling those external surfaces. By conducting the heat of combustion away from the ignited end of the cigarette and restricting the free flow of combustion supporting air to the ignited end of the cigarette the extinguisher functions to extinguish the cigarette in approximately 10 to 30 seconds unless a smoker draws on the outwardly projecting end of the cigarette remote from the ignited end thereof.
