摘要： The invention relates to a low ignition propensity cigarette having a self-extinguishing cigarette wrapper which is capable of self-extinguishing the cigarette. The cigarette wrapper comprises an oxygen storage and donor metal oxide to support and maintain free-burn of the self-extinguishing cigarette while retaining the low ignition propensity property of the self-extinguishing cigarette wrapper. The invention further relates to a low sidestream smoke cigarette having low ignition propensity properties. The wrapper has a composition which reduces sidestream smoke from a burning cigarette and comprises in combination, an oxygen storage and donor metal oxide catalyst and an essentially non-combustible finely divided porous particulate adjunct for the catalyst. The sidestream smoke reducing composition reduces porosity of the wrapper to render the cigarette as self-extinguishable. The oxygen storage and donor metal oxide catalyst is in an amount which supports free burn of the cigarette while retaining the self-extinguishing property of the cigarette wrapper.

摘要： A cigarette filter includes a multiple section filter which reduces the level of predetermined smoke constituents. The filter includes a fibrous filter plug section, a selective adsorbent section, and a general adsorbent section co-axially aligned in tandem. The selective adsorbent section includes a selective absorbent material which is a phenol-formaldehyde resin matrix surface-functionalized with mainly primary and secondary amine functional groups which removes specific smoke constituents from the tobacco smoke. The general adsorbent section is a material capable of adsorbing a range of chemical compounds without a high degree of specificity.

摘要： A cigarette filter that includes a multiple section filter which reduces the level of predetermined smoke constituents. The filter (130) consists of a fibrous filter plug (132) located at the mouth-end of the cigarette, a section (136) containing a selective adsorbent material, and a section (134) containing a general adsorbent material. The selective adsorbent material, such as a phenol-formaldchyde resin matrix surface-functionalized with mainly primary and secondary amine functional groups, removes specific smoke constituents from the tobacco smoke. The general adsorbent material, such as activated charcoal, is preferably capable of adsorbing a range of chemical compounds without a high degree of specificity. Structurally, the fibrous filter plug, the selective adsorbent section, and the general adsorbent section are co-axially aligned it tandem.

摘要： A smoking article such as a cigarette comprises a tobacco rod and a filter component having a cavity filled with spherical beaded carbon. As mainstream tobacco smoke is drawn through the filter component, targeted gas phase smoke constituents are removed as the smoke passes through the carbon. During the filter manufacturing process the spherical beaded carbon flows like a liquid and substantially completely fills the cavity. Point-to-point contact between the spherical beads together with substantially complete filling of the cavity produces minimal channeling of ambulatory gas phase as well as maximum contact between the gas phase and the carbon surface of the spherical beads during smoking.
