  • Publication number: 20110083675
    Abstract: A smoking article filter includes a valved flow restrictor and a cavity downstream of the flow restrictor. The flow restrictor includes an orifice or flow channel for directing smoke into the cavity. The filter is attached to the tobacco rod with tipping paper and includes an air-admissible ventilating zone at a location downstream of the restrictor. The valved restrictor can be used to isolate a sorbent bearing component of the filter from a flavor bearing component.

  • Patent number: 7914622
    Abstract: A smoking article includes a cylinder of smoking material having at least one hollow tube having a heat conductive wall within the cylinder of smoking material and a filter system attached to the cylinder of smoking material. The filter system includes an adsorbent material therein. The at least one hollow tube extends from within the cylinder of smoking material through the adsorbent material. At least one flavorant material 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.

  • Patent number: 7866324
    Abstract: A cigarette having a multi-component filter wherein an upstream sorbent removes at least one constituent from mainstream tobacco smoke passing through the filter and a downstream flavor segment compensates for taste lost to the sorbent. The flavor component includes cellulosic flavor bearing granules which release volatile flavor constituents into the mainstream smoke under ambient conditions. The cellulosic granules include microcrystalline cellulose or other cellulosic material which can be formed into a paste with the flavor additive, extruded and spheronized to form the flavor granules.

  • Publication number: 20100294289
    Abstract: A filtered cigarette possesses a smokable rod and a filter element. The smokable rod is secured to the filter element using tipping material. The cigarette possesses more than one layer of tipping material. An outer layer of tipping material can overlie at least a portion of an underlying inner layer of tipping material, and during use by the smoker, the outer layer can be removed from the cigarette. Thus, it is possible for a cigarette manufacturer to provide a cigarette that can be used as such by the smoker, or that can be adapted by the smoker to provide a different sensory experience (e.g., the visual, organoleptic, trigeminal, aromatic, and tactile characteristics of the cigarette can be altered by removal of the outer tipping material). Alternatively, the use of the outer layer of tipping material can be used to improve the physical integrity of the cigarette.

  • Publication number: 20100282267
    Abstract: An encapsulated flavorant or artificial sweetener for use with smokeless tobacco and related products. The encapsulated flavorant or artificial sweetener comprises a core encapsulated with a lipid-based coating that provides stability when in contact with tobacco, yet releases flavor over time when the product is used. The core comprises a carrier, such as silica, tobacco, beet fiber, citrus fiber, artificial sweetener, or the like, coated or loaded with a flavorant. Flavor loading may be in the range of approximately 10% to 60%, by weight. Flavorants include, but are not limited to, methyl salicylate (oil of wintergreen), cinnamon (e.g., cinnamon oil), peppermint (e.g., peppermint oil), and spearmint (oil of spearmint).

  • Publication number: 20100154809
    Abstract: A multi-component filter for a smoking article comprises: a mouth end segment; a first flavour release segment comprising plant leaf upstream of the mouth end segment; and a second flavour release segment comprising filtration material and a flavourant upstream of the first flavour release segment. The resistance to draw of the second flavour release segment is greater than the resistance to draw of the first flavour release segment and the resistance to draw of the second flavour release segment is greater than the resistance to draw of the mouth end segment. The multi-component filter preferably further comprises a rod end segment comprising filtration material upstream of the second flavour release segment, which has a lower resistance to draw than the second flavour release segment.
