A cigarette includes an ignition element in contact with tobacco, surrounded by a composite outer wrapper. The outer wrapper is impervious to oxygen causing the tobacco to extinguish between puffs. The ignition element, however, has a longer static burn time than the tobacco and remains smoldering between puffs. Upon a subsequent puff, the smoldering ignition element re-ignites the tobacco. One or more initially-occluded perforations in the outer layer maintain the uniformity in combustion of the tobacco and ignition element.
144	Cigarette sidestream smoke treatment material	US10805237	2004-03-22	US20040173231A1	2004-09-09	Larry Bowen; Stanislav M. Snaidr; E. Robert Becker; Warren A. Brackmann
A cigarette sidestream smoke treatment material made from a sheet of non-combustible active components provides a porous structure capable of treating sidestream smoke. The treatment material, as used in combination with a cigarette, provides a low sidestream smoke emitting cigarette unit. The material has a porosity which encourages a conventional free-burn rate of a conventional cigarette. The material may comprise a sorbent capable of sorbing components of the sidestream smoke, and an oxygen storage component which releases oxygen at free-burn rate temperatures to ensure that conventional free-burn rate is maintained and to enhance the oxidation treatment of the adsorbed non-aqueous components. Preferably, an oxidation catalyst is included in the material and most desirably the oxygen storage component may also function as the oxidation catalyst. Particularly preferred materials which perform the dual function are oxides of cerium.

148	Cigarette	US246712	1994-05-20	US5497794A	1996-03-12	Yutaka Okumoto
A cigarette is manufactured by executing a cigarette manufacturing process. In a cut tobacco supply process of the manufacturing process, tobacco shreds are attracted by suction onto a first tobacco band to form a cut tobacco layer. The cut tobacco layer delivered from the first tobacco band is folded into layer portions within a limited space, thereby forming a cut tobacco train. During formation of the cut tobacco train, the tobacco shreds are arranged so that their leaf surfaces cross at right angles to the direction of delivery of the cut tobacco layer. Then, the cut tobacco train is attracted by suction onto a second tobacco band, and is delivered at a speed later than a speed of delivery of the cut tobacco layer. The cut tobacco layer is permitted to be folded in the cut tobacco train because there is a difference in a delivery speed between the cut tobacco layer and the cut tobacco train. Further, the cut tobacco train is wrapped in a paper web to form a cigarette rod, and the formed cigarette rod is cut into individual cigarettes with a predetermined length. In the cigarette, the tobacco shreds are arranged so that their leaf surfaces cross at right angles to the axis of the cigarette. Therefore, the cigarette becomes harder, so that ability to maintain the appearance of the cigarette can be improved.

150	Multiple-smoking cigarette system	US968591	1992-10-29	US5379788A	1995-01-10	Larry Bowen; Warren A. Brackmann; Norman Cohen; George Fazekas; Joseph Heffernan; Peter P. Kaczmarek; Stanislav M. Snaidr
A novel cigarette system is described which has a greater number of puffs than a conventional cigarette of same dimensions and length of tobacco rod, namely at least about 14 puffs. The cigarettes are intended to be partially smoked, extinguished, stored and then resmoked. A filter is attached to the tobacco rod of the cigarette constructed to provide a per-puff delivery profile of tar, nicotine and flavor to the smoker which is approximately the same for both smokings of the cigarette. The greater-than-normal number of puffs may be achieved by employing a slower burning tobacco blend, greater tobacco density and/or burn rate retardant paper. An extinguishing and storage device is provided to extinguish the cigarette after the initial smoking of the cigarette and to store the extinguished cigarette between smokings.

A cigarette having a circumference of about 25 mm includes a rod of tobacco cut filler having a circumference of about 12.5 mm which is in turn circumscribed by an air permeable insulating material. The tobacco cut filler has a packing density of less than about 400 mg/cm.sup.3. The insulating material comprises a fibrous material (e.g., glass fibers), and has a radial thickness of greater than about 0.25 mm, and often greater than about 0.5 mm. The insulating material is in turn circumscribed by a paper wrapping material having a low air permeability (e.g., less than about 15 CORESTA units). The cigarette includes a filter element at one end. The cigarette yields low levels of visible sidestream smoke.
158	Cigarette and smokable filler material therefor	US567519	1990-08-15	US5101839A	1992-04-07	Stephen W. Jakob; Michael D. Shannon; Olivia D. Furin; Paul F. Bernasek; Richard L. Blakley; Johnny L. Brooks; Karen M. Womble; Gary R. Shelar; James L. Resce
A smokable filler material includes an aerosol forming material (e.g., propylene glycol and glycerin) and a binding agent (e.g., ammonium alginate). Tobacco extracts and/or pieces of tobacco laminae can be incorporated into the smokable filler material, and/or the smokable filler material can be blended with tobacco cut filler. The amount of aerosol forming material within the smokable filler material typically is at least about 20 percent, based on the weight of that smokable filler material. Cigarettes are provided by wrapping the smokable filler material in a paper wrapping material. A typical paper wrapping material has a porosity of less than about 5 CORESTA units. Cigarettes cn include two layers of circumscribing paper wrapping materials. Cigarettes also can include filter elements.

Cigarettes which yield very low levels of sidestream "tar" during use comprise a paper wrapper having an air permeability of less than about 10 CORESTA units, and a blend of a tobacco filler material and a second smokable material. The second smokable material preferably includes about 60 weight percent calcium carbonate, about 30 weight percent pyrolyzed alpha-cellulose and about 10 weight percent carboxymethyl cellulose. Such cigarettes, when used, generate very low amounts of sidestream "tar", and hence, very low levels of visible sidestream smoke.
160	Barrierized cigarette	US336443	1981-12-31	US5072743A	1991-12-17	Charles P. Perrine
Differentiation of surface is utilized for the prevention or arrest of forward finger edge slippage along the surface of a cigarette under new perception and consideration of all significant factors, including the human factor. Provision is sometimes included for automatic extinguishing of the cigarette or destruction of its smokable utility prior to dissipation of the means against slippage. A cigarette is manufactured having predetermined control against its being smoked or burned the full length of its tabacco content. Means employed are varying adaptations of physics and chemistry but basic is either the principle of smothering or the utilization of combustion itself, or its product heat, in self defeating adaptation.
