Patent number: 7836895Abstract: A filtered cigarette possesses at least one breakable capsule in its filter element. The filter element can possess a central cavity extending from the cigarette tobacco rod towards the middle of the filter element. The central cavity may be defined by an inner filter portion. The inner filter portion can be surrounded by an outer filter portion comprised of filter tow material that is generally permeable to the smoke generated by the cigarette. At least one breakable capsule is disposed in the central cavity of the filter element. The breakable capsules are spherical in shape, and are composed of a gelatin outer shell that encloses a payload of triglycerides and flavoring agents. The breakable capsules are adapted to rupture in response to pressure applied by the smoker to the outside region of the filter element.Type: GrantFiled: June 23, 2003Date of Patent: November 23, 2010Assignee: R. J. Reynolds Tobacco CompanyInventors: Michael Francis Dube, Kenneth Wayne Smith, Vernon Brent Barnes

Patent number: 7825305Abstract: The present invention provides a method for producing plants with a desired phenotypic trait which comprises subjecting plants to mutagenesis, screening chimeric progeny for plants having the desired phenotypic trait, and propagating the survivors. In an embodiment, the phenotypic trait comprises an altered amino acid content. Preferably, the technique is used to generate Nicotiana tobacum plant lines having an increase in at least one amino acid. In a preferred embodiment, the invention provides improved Nicotiana tobacum plant lines producing at least 1.35 nmole of threonine per milligram of dry plant weight. These plants are useful for improving the flavor and aroma of the tobacco.Type: GrantFiled: October 20, 2006Date of Patent: November 2, 2010Assignee: Reynolds Technologies, Inc.Inventors: Luis Mayan Dominguez, Jerry Wayne Lawson, Wennuan Liu, Michael Francis Dube

Patent number: 7789089Abstract: 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.Type: GrantFiled: August 4, 2006Date of Patent: September 7, 2010Assignee: R.

Patent number: 5709227Abstract: A degradable smoking article comprises a tobacco rod and a filter component made of a gathered web of moisture disintegrative sheet material wrapped with a moisture disintegrative plug wrap bonded along a longitudinal seam with a water soluble adhesive. A moisture disintegrative tipping paper coated on one side with a water soluble adhesive secures the tobacco, rod and filter component together. The combination of moisture and other natural elements such as sunlight, mechanical abrasion, etc., dissociates the components of the smoking article over a relatively short period of time. Other embodiments of the filter component include a hollow degradable tube and a monolithic extruded starch filter rod.Type: GrantFiled: December 5, 1995Date of Patent: January 20, 1998Assignee: R.
