  • Patent number: 5269327
    Abstract: 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: Grant
    Filed: August 7, 1991
    Date of Patent: December 14, 1993
    Assignee: Philip Morris Incorporated
    Inventors: Mary E. Counts, Bernard C. LaRoy, D. Bruce Losee, Jr., Constance H. Morgan, Ulysses Smith, F. Murphy Sprinkel, Jr., Francis V. Utsch
  • Patent number: 5261424
    Abstract: A control device for electrically heated flavor generators. Sensors detect user lip activity associated with taking a draw and trigger heating of flavor-generating materials.
    Type: Grant
    Filed: May 31, 1991
    Date of Patent: November 16, 1993
    Assignee: Philip Morris Incorporated
    Inventor: F. Murphy Sprinkel, Jr.
  • Patent number: 5228460
    Abstract: A heating element to provide heat to a tobacco flavor medium, for use in an electrical smoking article, by converting electrical energy to heat through the use of a material with electrically resistive properties is provided. The material is arranged in a radial array of blades with a current density profile such that a maximum area of each blade provides heat to the tobacco flavor medium dispersed thereon. The blade is generally U-shaped to assure dispersion of heat evenly to avoid hot spots along the blade and is tapered to reduce mass toward the mouth end of the heating element so as to maximize the heated area.

  • Patent number: 5179966
    Abstract: An article is provided in which a flavor generating medium is electrically heated to combustion to evolve inhalable flavors or other components in vapor and/or aerosol form. The article has a plurality of charges of the flavor generating medium which are heated to combustion sequentially to provide individual puffs.
    Type: Grant
    Filed: December 17, 1991
    Date of Patent: January 19, 1993

  • Patent number: 5154192
    Abstract: 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: Grant
    Filed: July 18, 1989

  • Patent number: 4987908
    Abstract: 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.
