Patent number: 7578298Abstract: 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.Type: GrantFiled: February 4, 2005Date of Patent: August 25, 2009Assignee: Philip Morris USA Inc.Inventors: Georgios Karles, Martin Garthaffner, Richard Jupe, Diane Kellogg, Ila Skinner, Jose Nepomuceno, John Layman, Constance Morgan, Jay A Fournier

Patent number: 7249605Abstract: This invention relates to the provision in a cigarette filter element of a capsule containing a deodorizer. The capsule is resistant to the handling endured before and during smoking, yet ruptures to release or expose the deodorizer upon extinguishing of the smoked cigarette. The deodorizer may comprise neutralizing or masking agents, or mixtures of both.Type: GrantFiled: October 10, 2003Date of Patent: July 31, 2007Assignee: British American Tobacco (Investments) Ltd.Inventors: Kevin Gerard MacAdam, Rosemary Elizabeth O'Reilly, Nigel David Warren

Publication number: 20040261807Abstract: 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: ApplicationFiled: June 23, 2003Publication date: December 30, 2004Inventors: Michael Francis Dube, Kenneth Wayne Smith, Vernon Brent Barnes

Publication number: 20040159327Abstract: A smoking article includes a cylinder of smoking material, a filter attached to the cylinder of smoking material, and a tube of preferably porous and/or perforated material adapted to collapse at an open end upon exposure to thermal energy and preferably extending from one end portion of the smoking material to the junction of the filter and the cylinder of smoking material. Thermal energy generated by a burning portion of the tobacco filler material within the cylinder of smoking material is transferred by convection through the open portion of the tube after the end portion of the tube has collapsed closed by the heat from the burning portion of the tobacco.Type: ApplicationFiled: February 14, 2003Publication date: August 19, 2004Inventor: Henry M. Dante

Patent number: 5746231Abstract: A tobacco smoke filter comprising a porous substrate having a humectant, such as sodium pyroglutamate, dispersed therein to absorb moisture from the tobacco smoke thereby wet-filtering the tobacco smoke. The tobacco smoke filter can also comprise a porous substrate having microcapsules dispersed therein. The microcapsules can comprise a humectant such as sodium pyroglutamate. The microcapsules further preferably comprise one or more of methylcellulose, chlorophyllin and at least one vegetable oil. The tobacco smoke filter can also comprise a porous substrate having dry water and a porphyrin dispersed therein. The tobacco smoke filter can also comprise a porous substrate having a copper-containing porphyrin dispersed therein.Type: GrantFiled: May 15, 1996Date of Patent: May 5, 1998Assignee: Craig LesserInventors: Craig Lesser, Reid W. Von Borstel
