Abstract:
A smoking article such as a cigarette (10) comprises a tobacco rod (12) and a filter component (14) having a cavity (22) filled with spherical beaded carbon (24). As mainstream tobacco smoke is drawn through the filter component (14), targeted gas phase smoke constituents are removed as the smoke passes through the carbon (24). During the filter manufacturing process, the spherical beaded carbon (24) flows like a liquid and substantially completely fills the cavity (22). Point-to-point contact between the spherical beads (24) together with substantially complete filling of the cavity (22) produces minimal channeling of ambulatory gas phase as well as maximum contact between the gas phase and the carbon surface of the spherical beads (24) during smoking.
Abstract:
A smoking article 10 has a cylinder 20 of smoking material and a central tube 60 within the cylinder of the smoking material wherein heat is convectively transferred with smoke from a lit end of the cylinder of smoking material through the central tube to a mouth end of the cylinder of smoking material in each puff. A filter system 40 is attached to the cylinder of smoking material, and includes a plurality of segments, wherein at least one of the plurality of segments contains flavorant 72 and aerosol forming agents 74 encapsulated in at least one breakable capsule 70.
Abstract:
Provided is a method of encapsulating a hydrophilic substance (20) with wax. Also provided, is a method of encapsulating honey with an edible wax to create honey capsules. The method includes ejecting a droplet of the hydrophilic substance (20) into a stream of molten wax (25) and allowing the droplet to pass through the molten wax (25) to enter a container of water (30). The wax capsule (35) forms an oral product that may be placed in the mouth or used in conjunction with other edible or oral products.
Abstract:
A smoking article (10) having a cylindrical tube (22) of smokable material (21) having an outer wrapper (30) , a concentric rod (24) of smokable material (21) coaxially positioned within the cylindrical tube (22) of a smokable material (21) , and an inner wrapper (60) separating the cylindrical tube (22) and the concentric rod (24) . A filter (40) attaches to the tobacco rod (20) with an annular film (70) positioned between the filter (40) and the tobacco rod (20) . The annular film (70) increases the resistance-to-draw of the cylindrical tube (22) during smoking.
Abstract:
A method for providing an encapsulated flavorant or chemesthetic agent in a smoking article comprises forming an emulsion comprising: (i) a first aqueous solution, comprising one or more cross-linkable polysaccharides; and (ii) a hydrophobic additive comprising one or more flavorants or chemesthetic agents. The method also comprises extruding the emulsion into a second aqueous solution in the form of an elongated structure, cross-linking at least a portion of the one or more cross-linkable polysaccharides, removing the cross-linked elongated structure from the second aqueous solution, introducing the cross-linked elongated structure into a filter, or into a rod comprising a smoking composition, or both; and forming the filter or the rod of the smoking composition into a smoking article. The method can include a drying step. A smoking article comprising a rod comprising a smokable composition; and one or more cross-linked elongated structures produced by the method of the invention is also disclosed. A smokable material comprising tobacco and one or more cross-linked elongated structures produced by the method of the invention is also disclosed.
Abstract:
A smoking article 10 includes a cylinder 20 of smoking material 21 having at least one hollow tube 60 having a heat conductive wall 68 within the cylinder of smoking material and a filter system attached to the cylinder of smoking material. The filter system 40 includes an adsorbent material 76 therein. The at least one hollow tube extends from within the cylinder of smoking material through the adsorbent material. At least one flavorant material 80 is retained within the at least one hollow tube, and upon exposure to heat from the heat conductive wall of the hollow tube the flavorant material releases a flavorant.
Abstract:
A surface-modified activated carbon is provided to reduce the amount of free fine carbon particles among the activated carbon. By surface-modifying the activated carbon with a layer, the activated carbon can have increased mechanical strength and the fine carbon particles among the activated carbon can be fastened to the layer. Therefore, the layer allows for the level of free fine carbon particles among the activated carbon to be reduced. Surface-modified activated carbon can be used in smoking articles so as to allow for adsorption by the activated carbon with reduced free fine carbon particles in the smoking article and the smoke produced.

Abstract:
Provided is a method for cooling wax after coextrusion to create wax capsules 150. The method includes immersing a concentric nozzle 100 of a coextruder in a container of heated alcohol 200. The container of heated alcohol sits in a water-ice bath 210 to create a temperature gradient. A core material 155 having a wax coating 160 is extruded through a concentric nozzle to form a capsule. The capsule enters the container of hot alcohol where the wax coating is solidified. In an embodiment, the method is a continuous method including a capsule and solvent transfer system 300, 350, 400, 425, 450.
