  • Patent number: 5692526
    Abstract: A novel cigarette of an electrical cigarette system and method of making same, the cigarette comprising a tubular tobacco web and a plug disposed within said tubular tobacco web which provides a structural connection that remains intact after a smoking of the cigarette. The disclosure includes a double-belled plug extending between a free end and a tipped end of a tobacco rod, or in the alternative, a column of tobacco with higher and lower density segments. The disclosure includes a method comprising the steps of producing a continuous plug, passing same through a die, overwrapping the rod with tobacco mat and overwrap, and severing the rod.

  • Patent number: 5479948
    Abstract: An electrical smoking article is provided in which tobacco flavor medium is carried past a heater by a continuous web. The web, which preferably is substantially non-combustible, may bear continuous tobacco flavor medium or spaced-apart portions of tobacco flavor medium. A flavor cassette for such an electrical smoking article is also provided. The cassette resembles a conventional recording tape microcassette, having the web in place of magnetic tape. The cassette may also include the heater past which the tape is indexed to heat individual portions of tobacco flavor medium.

  • Patent number: 5417228
    Abstract: This invention relates to the control of the burn rate of a cigarette. The burn rate is controlled by the use of a paper wrapper to which regions of cellulosic material is applied and bonded. The cellulosic material is applied during a manufacturing step for the base paper wrapper, either off or on-line of the paper wrapper-forming machine.

  • Patent number: 5345951
    Abstract: 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.

  • Patent number: 5146934
    Abstract: This invention relates to a heat source comprising a mixture of metal carbide, metal nitride and metal which undergo a staged ignition process, particularly useful in smoking articles. The metal carbide/metal nitride/metal mixtures making up the heat source have ignition temperatures that are substantially lower than conventional carbonaceous heat sources, while at the same time provide sufficient heat to release a flavored aerosol from a flavor bed for inhalation by the smoker. Upon combustion the heat source produces substantially no carbon monoxide or nitrogen oxides.
