Patent number: 5865185Abstract: A smoking article is provided in which a replaceable tobacco flavor unit containing tobacco flavor material is electrically heated by a set of permanent reusable heaters to evolve flavors or other components in vapor or aerosol form for delivery to a smoker. Each heater heats only a portion of the available tobacco flavor material so that a plurality of individual puffs of tobacco flavor substance can be delivered sequentially to the smoker. The replaceable tobacco flavor unit can also include a filter to reduce the effect of residual aerosol which settles or condenses on the permanent portions of the article and which can result in undesirable flavor generation when reheated. A method and apparatus for manufacturing the replaceable tobacco flavor unit is also provided.Type: GrantFiled: May 24, 1995Date of Patent: February 2, 1999Assignee: Philip Morris IncorporatedInventors: Alfred L. Collins, Mary Ellen Counts, Amitabh Das, Seetharama C. Deevi, Grier S. Fleischhauer, Charles T. Higgins, Willie G. Houck, Jr., Billy J. Keen, Jr., Robert E. Lee, III, A. Clifton Lilly, Jr., D. Bruce Losee, Jr., Hugh J. McCafferty, Constance H. Nichols, Wynn R. Raymond, Robert L. Ripley, Renzer R. Ritt, Sr., G. Robert Scott, F. Murphy Sprinkel, Michael L. Watkins, Susan E. Wrenn, Francis V.

Patent number: 5345951Abstract: A smoking article in which a flavored aerosol is generated by heat transfer to a flavor bed from the combustion of a heat source is provided. The article generates substantially no sidestream smoke. The transfer of heat from the heat source to the flavor bed is accomplished by convective and radiative heat transfer.Type: GrantFiled: August 12, 1992Date of Patent: September 13, 1994Assignee: Philip Morris IncorporatedInventors: Mark A. Serrano, Kenneth S. Houghton, Harry V. Lanzillotti, Edward B. Sanders, A. Clifton Lilly, Jr., Charles R. Hayward, John R. Hearn, D. Bruce Losee, Jr., Grier S. Fleischhauer, Willie G. Houck

Patent number: 5269327Abstract: An article is provided in which a tobacco flavor medium is electrically heated to evolve inhalable tobacco flavors or other components in vapor or aerosol form. The article has a plurality of charges of the tobacco flavor medium which are heated sequentially to provide individual puffs.Type: GrantFiled: August 7, 1991Date of Patent: December 14, 1993Assignee: Philip Morris IncorporatedInventors: Mary E. Counts, Bernard C. LaRoy, D. Bruce Losee, Jr., Constance H. Morgan, Ulysses Smith, F. Murphy Sprinkel, Jr., Francis V. Utsch

Patent number: 5159940Abstract: A smoking article in which a flavored aerosol is generated by heat transfer to a flavor bed from the combustion of a carbon heat source is provided wherein the carbon heat source and the flavor bed are contained within a non-combustible substantially cylindrical hollow ceramic sleeve. The article generates substantially no sidestream smoke. The transfer of heat from the heat source is accomplished by convective and radiative heat transfer.Type: GrantFiled: July 22, 1988Date of Patent: November 3, 1992Assignee: Philip Morris IncorporatedInventors: Charles R. Hayward, Harry V. Lanzillotti, David E. Merrill, Edward B. Sanders, D. Bruce Losee, Jr., John R. Hearn

Patent number: 5154192Abstract: Thermal indicators for non-combustion smoking articles which chemically react when heated to provide visual indications of temperature changes are disclosed. The indicators comprise organic acids, sugars, or amines combined with sugars. The indicators are printed in a variety of patterns along the length of the smoking articles to show temperature changes and to indicate whether the smoking article is finished and should be discarded.Type: GrantFiled: July 18, 1989Date of Patent: October 13, 1992Assignee: Philip Morris IncorporatedInventors: F. Murphy Sprinkel, John M. Campbell, D. Bruce Losee, Jr.

Patent number: 4987908Abstract: Thermal indicators for non-combustion smoking articles which physically change when heated to provide visual indications of temperature changes are disclosed. The indicators comprise waxes or other compounds which melt away to reveal colored substrates, or comprise microencapsulated chemicals which are released when heated to cause inking or dyeing. The thermal indicators are printed in variety of patterns along the length of the smoking articles to show temperature changes and to indicate whether the smoking article is finished and should be discarded.Type: GrantFiled: July 18, 1989Date of Patent: January 29, 1991Assignee: Philip Morris IncorporatedInventors: F.

Patent number: 4981522Abstract: A flavor source to be used as a thermally releasable flavorant for smoking articles that do not combust tobacco. The material includes tobacco particles, an aerosol precursor that forms an aerosol upon exposure to heat, and a filler material that absorbs and radiates heat to minimize the likelihood that the flavor material will ignite. The material is mixed in an extruder, extruded through a die, and cut into pellets having a substantially uniform shape. The pellets are loaded into a chamber for inclusion in a smoking article as a flavor generator.Type: GrantFiled: July 22, 1988Date of Patent: January 1, 1991Assignee: Philip Morris IncorporatedInventors: Walter A. Nichols, Harry V. Lanzillotti, Richard A. Thesing, Alex S. Gergely, Constance H. Morgan, Bruce E. Waymack, D. Bruce Losee, Jr., John R. Hearn, Johnny L. Miller
