摘要： Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The sealed capsule or capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material from the one or more capsules and expose the additive material to mainstream smoke passing through the filter. The sealed capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use.

摘要： Smoking articles, filters, and methods for selectively removing selected components from tobacco smoke are disclosed. The smoking articles and filters include composites composed of a porous alumina and/or aluminosilicate matrix containing particles of activated carbon and zeolite molecular sieve adsorbents distributed throughout the matrix which can selectively remove selected components of tobacco smoke. The composites may be made by admixing the adsorbent mixture and a binder such as aluminum hydroxide or montmorillonite clay, adding an aqueous mineral acid to gel the mixture and drying and firing the gel paste. The proportions and adsorption capacities of the components can be selected to tailor the adsorption characteristics of the composites to selectively remove targeted constituents such as acrolein and 1,3-butadiene in tobacco smoke. Methods for making filters and smoking articles using the composites, as well as methods for smoking products comprising the composites, are also provided.

摘要： Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The capsule or capsules are provided between first and second absorbent members and the capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material and expose the additive material to mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. An outer cover which is impermeable to the fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members.

摘要： An activated carbon substrate which is pre-treated to make an exposed surface of the activated carbon substrate substantially hydrophilic, coated with a carbon precursor to form a coated activated carbon, and then the coated activated carbon substrate is heated to carbonize the carbon precursor to from the modified activated carbon. The modified activated carbon comprises a uniform porous carbon membrane formed on an exposed surface of the activated carbon substrate. The carbon membrane can mediate the absorption and/or adsorption kinetics of the activated carbon substrate. The modified activated carbon, which can be incorporated into one or more components of a cigarette, can selectively remove gaseous constituents from mainstream smoke during smoking.
