Abstract: Flavor carriers, smoking articles, method of making flavor carriers, methods of making smoking articles, methods of flavoring gas streams such as mainstream tobacco smoke and methods of smoking are provided. The flavor carriers and smoking articles comprise a mesoporous molecular sieve and a flavor releasably disposed within the sieve.

Abstract: 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.

Abstract: A cigarette filter for removing gas phase constituents from mainstream cigarette smoke as the smoke is drawn through the filter primarily comprises an activated carbon fiber filter section including a bundle of activated carbon fibers. Particulate adsorbent materials such as granules, beads or course powders may be dispersed amongst the activated carbon fibers to aid in removal of the gas phase constituents. Additionally, the activated carbon fiber filter section may be used in combination with a separate bed or beds of particulate adsorbent material. In one embodiment, the activated carbon fibers are positioned within a helical groove on the outside of a threaded rod within the activated carbon fiber filter section. Relatively smaller amounts of activated carbon fibers produce the same smoke constituent reduction as larger amounts of particulate adsorbent material.

Abstract: Flavored carbon useful as a filtering material of a smoking article such as a cigarette is made by applying liquid flavorant to activated carbon particles in a fluidized bed. The flavored carbon can be used to impart desired taste to mainstream smoke while removing one or more components from mainstream smoke.

Abstract: A method and apparatus are disclosed for applying foamed material to tobacco, and for drying and setting the foamed material, particularly in connection with the making of cigarettes. The foamed material may be added to the tobacco, for example, in the paper guide section of a cigarette maker, at the garniture mouth or through the short tongue or through both, or at the chimney. Drying and setting can occur in the chimney, on the vacuum belt, or in the garniture, after the material has been applied to the tobacco filler. Drying can be accomplished, for example, by using heated air or microwave radiation. Addition of material to tobacco filler, during the cigarette making process in the form of a foam, results in a cigarette in which the material added is more uniformly distributed.

Abstract: Methods and apparatus for applying liquid strands containing additives to cigarette rods. Liquid is extruded to form one or more strands that are applied to loose tobacco filler in the chimney section of a conventional cigarette maker. The liquid has a viscosity that prevents it from soaking through the tobacco and contacting the cigarette maker or the cigarette wrapper. Additives to the liquid strands include flavorants, burn inhibitors, and burn accelerators.

Abstract: A tobacco product characterized by improved void volume and firmness characteristics and a method of making a tobacco product by applying binder material to tobacco filler, treating the filler to the extent necessary to cause the filler to become substantially non-tacky, forming a rod, activating the binder and treating the rod to the extent necessary to cause the filler shreds to become bonded to one another.

Abstract: Apparatus and a method for processing hot, moist extruded tobacco-containing materials as they are continuously extruded by drying the extruded material rapidly with microwave energy, and then cooling the extruded material rapidly so that the surface temperature of the extruded material is decreased below the bulk temperature to provide the extruded material with an adequately rigid and stable dimensionally structure that can be formed into a smoking article. Microwave drying provides substantially uniform drying without case hardening the material. Cooling may occur by passing air at high velocity, refrigerated air or presenting a partial vacuum across the advancing extruded material, or contacting the material with cold contacting members or a cryogenic bath. Conventional maker devices can be used for forming smoking articles from the dried and cooled extruded material.

Abstract: An extruded, coherent, multistrand, tobacco-containing, generally cylindrical smoking article and a process for making it are disclosed. The smoking article contains a plurality of strands that are adhered to one another so as to form passageways between the strands, the passageways extending generally along the longitude of the smoking article. The configuration of the strands and passageways provides sufficient heat transfer area and/or residence time for the smoke drawn by a smoker to cool to an acceptable level.

Abstract: A substantially cylindrical foamed, extruded, tobacco-containing smoking article and a method of making the article. The article has properties substantially equivalent to a conventional cigarette. It contains from about 5 to about 98 wt. % of particulate tobacco, from 0 to about 60 wt. % of particulate filler, from about 2 to about 40 wt. % of a cellulosic binder selected from among hydroxypropyl cellulose, carboxymethyl cellulose, and its sodium, potassium and ammonium salts, cross-linked carboxymethyl cellulose, and its sodium, potassium and ammonium salts, hydroxyethyl cellulose, ethyl hydroxyethyl cellulose, hydroxypropyl methyl cellulose, methyl cellulose, ethyl cellulose, and mixtures thereof, and from about 5 to about 20 wt. % of water. The article has a density within the range of from about 0.05 to about 1.5 g/cc. The method of making such articles comprises the step of (a) dry blending the tobacco particles having an OV value of from about 3 to about 20% with from 0 to about 60 wt.

Abstract: A method and apparatus are disclosed for applying foamed material to tobacco, particularly in connection with the making of cigarettes. The foamed material may be added to the tobacco, for example, in the paper guide section of a cigarette maker at the garniture mouth (21) or through the short tongue (30) or through both, or at the chimney (10). Addition of a foamed material to the tobacco, during the cigarette making process, results in a cigarette in which the material added is more uniformly distributed.
