摘要： 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 the ignition element.

摘要： A flavor source to be used as a thermally releasable flavorant for smoking articles that do not combust tobacco. The flavor source includes tobacco particles, an aerosol precursor that forms an aerosol upon exposure to heat, and a gelling agent that imparts sufficient structural framework for rigidity to the flavor source. The material is mixed, extruded through a die, and cut into the shape of a one-piece flavor source. The flavor source is loaded into a chamber for inclusion in a smoking article as a flavor generator.

The material includes between about 70% and about 99% of at least one polypropylene homopolymer with a melt index of between about 1.2 to about 3.0 (measured according to ISO standard 1133 at 230.degree. C., 2.16 kgf) and a density of about 0.905 g/cc, and between about 1% and about 30% of at least one low density polyethylene homopolymer with a melt index of between about 0.9 and 3.0 (measured according to ISO standard 1133 at 190.degree. C., 2.16 kgf) and a density of about 0.921 g/cc.

摘要： An improved stuffer box used for crimping textile fibers, particularly fibrillated polyolefin films. The width of the stuffer box is related to the linear density of the fiber bundles to be crimped whereby there is one millimeter of width for each fiber bunder size in the range of from about 200 to about 750 denier. Pressure controlled hinged lid or fixed lid exit orifices may be employed. Also employed may be a distributing device for applying additive material to the textile fibers prior to crimping to enhance the crimping operation or to enhance the end use of the crimped fiber or both. Fibrillated polyolefin materials that are crimped in accordance with the invention are adapted for use as filter materials in smoking articles.

摘要： A filter cigarette is provided in which the smoker can select different flavorants or filter media for interposition in the smoke stream. A filter segment having two flow paths, each containing different flavoring or filtering media, cooperates with one or two rotatable end caps having openings for selective registration with the flow paths, are used to select the desired flow path. A method of delivering "air-swept flavor" is also provided.

摘要： A variable dilution filter cigarette is provided which includes a substantially cylindrical tobacco rod, an axially aligned, substantially cylindrical wrapped filter plug, and tipping paper which circumscribes the filter plug and joins the filter plug to the tobacco rod. The filter plug has first and second ends, which are open to permit the passage of air and smoke. The plug wrap is substantially air-impermeable and is divided into a mouth-end band, a central band, and a rod-end band having a first opening. The first and third bands are attached to the filter. The tipping paper is also substantially air-impermeable, circumscribes the filter plug, and extends from the mouth end of the filter plug to a position on the tobacco rod adjacent the rod end of the filter plug. The tipping paper is divided into first and second bands, the first band extending from the mouth end of the filter plug to a position overlying the rod-end band. The second band abuts the first band and overlaps and attaches the rod end of the filter plug to the abutting end of the tobacco rod. The first band is attached to the plug wrap only at the central band for rotation therewith about the longitudinal axis of the filter plug and has a second opening overlying the rod-end band such that the second opening is rotatable into registry with the first opening.

摘要： A filter cigarette is provided which comprises a tobacco rod which includes a charge of tobacco wrapped in cigarette paper, an integral, axially aligned cylindrical filter plug, and tipping paper. The filter plug is divided into first and second segments with the first segment being rotatable with respect to the second segment. Rotation of the first segment with respect to the second segment, in one embodiment of the invention, serves to vary the air dilution value of the cigarette. In another embodiment, rotation of the first segment with respect to the second segment produces variable resistance-to-draw in the cigarette. Both of the above embodiments can be combined into yet another embodiment to produce a cigarette which maintains a constant resistance-to-draw value as the air dilution value is varied. In yet another embodiment, an encapsulated flavorant is provided which is released responsive to rotation of the first segment with respect to the second segment. The flavorant release embodiment can be combined with the other embodiments.
