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： A process for producing a coated filter plug for a smoking article including: (a) incorporating an additive to a porous filter plug, thereby obtaining an impregnated filter plug; (b) coating a surface of the impregnated filter plug with a cross-linkable polymer material; and (c) cross-linking the cross-linkable polymer material, to form a cross-linked, breakable coating substantially enclosing the impregnated filter plug. The process may further include at least partially coating the impregnated filter plug with a cross-linking agent prior to, or subsequent to, coating with the cross-linkable polymer material.

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.

摘要： A method for providing particles of encapsulated flavorants or chemesthetic agents comprises forming an emulsion comprising: (i) a first aqueous solution, comprising one or more polysaccharides; and (ii) a hydrophobic additive; atomizing said emulsion in an atomizer into droplets; introducing said droplets into a second aqueous solution, comprising one or more metal cations, to form particles comprising one or more cross-linked polysaccharides and said additive encapsulated therein; and removing said particles from said second aqueous solution and drying said particles.
