Patent number: 4597397Abstract: A self igniting cigar stored in a tubular cartridge which is divided in three sections. The sections are secured through a sealed tape. When the sealed tape is removed the upper section can be pulled up from the middle section exposing the mouth piece of the cigar, allowing a smoker to grip the cigar to pull the cigar out of the remaining cartridge. This will ignite an igniting unit installed inside the cigar in the form of a flammable tube in which a piston is inserted attached to a string. The other end of string is anchored to the bottom surface of the cartridge. Therefore, when the cigar is pulled out of the cartridge, the piston is pulled out of the igniting tube, thereby igniting flammable substance in the igniting unit which ignites the cigar. The middle section is separated so that it can slide over the cigar to protect fingertips of smoker and to extinguish the butt.Type: GrantFiled: October 22, 1984Date of Patent: July 1, 1986Inventor: Friedrich Weinert

Patent number: 4489738Abstract: This invention concerns the use of specific coatings that are applied to the paper wrapper that encloses the cigarette's smoking medium for limiting in a predictable manner the free burning time of the treated cigarette, or controlling the lapsed time prior to self-extinguishment after being lit and left unattended. The coating materials are generally identified as hydrophylic colloids or aqueous-soluble polymers, that are deposited singly or as mixtures from aqueous media, and are represented by locust bean gum, pectin, sodium carboxymethylcellulose, and guar gum, forming adherent, non-tacky, flexible coatings on the paper housing substrates, and significantly altering the burning characteristic of the resultant cigarettes. Comparable behaviors are obtained, for equivalent weight percentages of the deposited solids, by either precoating the portion of paper wrapper that subsequently encloses the charge of tobacco or by post-treatment of the external surface of the assembled cigarette.Type: GrantFiled: March 7, 1983Date of Patent: December 25, 1984Inventor: Eli Simon

Patent number: 4452259Abstract: This invention relates to smoking articles having reduced free burn time, including cigarettes, cigars and little cigars. The smoking article comprises tobacco wrapped in a paper having at least one circumferential band printed between the ends of the smoking article; preferably at about the center of the smoking article. The band contains a substance which will cause the smoking article to extinguish in about 2-5 minutes under free burn conditions after the cone reaches the banded area if it is not puffed. The band is typically about 2-10 mm wide containing a substance which is a liquid in the temperature range of about 100.degree. C. to 200.degree. C. and which as the burning cone comes in contact with it provides a fluid film on the paper, without substantially penetrating through the surface of the paper, which film is substantially impervious to air and decomposes and/or distills endothermically from about 140.degree. C. to 300.degree. C.Type: GrantFiled: July 10, 1981Date of Patent: June 5, 1984Assignee: Loews Theatres, Inc.Inventors: Vello Norman, Arthur M. Ihrig

Patent number: 4319587Abstract: An improved smoking article, such as a cigarette or cigar, having means for controlling quickly, accurately and selectively the extent of consumption of the smoking article, to assist a habitual smoker in voluntarily curtailing or terminating his smoking habit. The control means comprises a generally tubular outer wrapping on the article on which are marked, printed, or otherwise imposed, spaced indicia in the nature of a scale, extending longitudinally of the article, and an annular control indicator mounted telescopically on the article and slidable axially relative thereto. The indicia may be accompanied by contrasting designs or markings, to provide quick, accurate and carefully selected voluntary control by the smoker of the extent of consumption of the smoking article. The annular control indicator contrasts visually relative to the smoking article.Type: GrantFiled: June 28, 1976Date of Patent: March 16, 1982Assignee: Irving S. MoserInventor: Irving S. Moser

Patent number: 4303084Abstract: This invention concerns the use of a class of coatings that are applied to the paper wrapper that encloses the cigarette's smoking medium, for limiting in a predictable manner the free burning time of the treated cigarette, or controlling the lapsed time prior to self-extinguishment after being lit and left unattended. The coating materials are generally identified as polymeric chlorine-containing film-forming latexes that cure at ambient temperature, forming flexible, water-resistant, flame-retardant deposits. Comparable results are obtained, for equivalent weight percentages of the deposited latex solids, by either pre-coating the portion of paper wrapper that encloses the charge of tobacco or smoking medium or by post-treatment of the external surface of the assembled cigarette.
