Abstract: A cigarette and cigarette paper have a plurality of multilayer bands formed by printing a highly viscous aqueous film-forming composition. After heating the composition to lower its viscosity, the bands are applied to the cigarette paper by gravure printing the composition. The composition is quenched and gelatinized by contact with the cool cigarette paper reducing absorption of water by the paper and reducing wrinkling, cockling, and waviness. Multiple gravure printed layers may be used to form the bands.

Abstract: A smoking article is provided in which a flavor-generating medium is heated electrically to release an aerosol for inhalation by a consumer. The smoking article includes a heater having resistive heating elements printed on a flexible substrate. The heater can be manufactured by circuit board mass production techniques, and can be formed to fit inside an article of the same shape and size as a conventional cigarette. Alternatively, the heater comprises an array of heating elements onto which charges of flavor-generating medium are deposited. The heating elements are connected in a manner which allows the temperature increase in the heater to be concentrated in individually selected heating elements, and requires a minimal number of electrical conductors.

Abstract: An improved carbonaceous heat source suitable for use in a smoking article is provided. The heat source is formed by mixing a carbon component, a catalytic precursor and a binder, forming the mixture into a shape, and supplying heat to the mixture. Upon combustion of the heat source, the catalytic precursor forms a catalyst that converts carbon monoxide produced during combustion of the heat source into a benign substance.

Abstract: A chemical heat source comprising metal nitride, metal oxide and carbon, particularly useful in smoking articles, and methods of making the heat source are provided. The metal nitride of the heat source has an ignition temperature substantially lower than conventional carbonaceous heat sources, while at the same time provides sufficient heat to release a flavored aerosol from a flavor bed for inhalation by the smoker. Upon combustion the heat source produces virtually no carbon monoxide. The metal nitride is prepared by pre-forming the starting materials into a desired shape, and converting them to metal nitride in situ, without substantially altering the shape of the starting materials.

Abstract: A flavor source to be used as a thermally releasable flavorant for smoking articles that do not combust tobacco. The material includes tobacco particles, an aerosol precursor that forms an aerosol upon exposure to heat, and a filler material that absorbs and radiates heat to minimize the likelihood that the flavor material will ignite. The material is mixed in an extruder, extruded through a die, and cut into pellets having a substantially uniform shape. The pellets are loaded into a chamber for inclusion in a smoking article as a flavor generator.
