Abstract
Abstract A cigarette of improved type, and which is centrally contained within a tubular sleeve or case so to enclose the cigarette flame for preventing accidental fires, the case having a front end wall that is perforated so to allow igniting the cigarette and admit air for maintaining the cigarette flame. The cigarette may be ignited by means of an elongated member extending through the front end wall, the member having a portion arranged to cover the perforations in the end wall and being lightly adhered thereto before use; the cigarette having its front end coated with a ring of ignitable material and the rear end portion of the elongated member having an enlarged abrasive surface thereon on such that the abrasive material will cause ignition of the cigarette end upon relative axial movement thereof.
