Patent number: 5598868Abstract: A smokable filler material includes an aerosol forming material (e.g., glycerin) and as binding agent. Tobacco extracts and/or pieces of tobacco laminae can be incorporated into the smokable filler material, and/or the smokable filler material can be blended with tobacco cut filler. The amount of aerosol forming material within the smokable filler material typically is at least about 20 percent, based on the weight of that smokable filler material. Cigarettes are provided by wrapping the smokable filler material in a paper wrapping material. A typical paper wrapping material has a porosity of less than about 5 CORESTA units.Type: GrantFiled: November 30, 1994Date of Patent: February 4, 1997Assignee: R. J. Reynolds Tobacco CompanyInventors: Stephen W. Jakob, Michael D. Shannon, Olivia D. Furin, Paul F. Bernasek, Richard L. Blakley, Johnny L. Brooks, Karen M. Womble, Gary R. Shelar, James L. Resce

Patent number: 5415186Abstract: Disclosed is a stabilized substrate composition for smoking articles, particularly cigarettes. In general, the stabilized substrate composition comprises an admixture of a binder and an aerosol forming material which plasticizes the binder, together with optional fillers and/or base materials. In the stabilized substrate compositions of the present invention the relative amounts of binder and aerosol former depend particularly on the situation in which the substrate composition is used. In general, the ratio of aerosol former to binder is between about 3:1 and about 40:1. When the stabilized composition is used on a base material such as tobacco cut filler, the ratio of aerosol former to binder should be at least about 15:1, and preferably is from about 25-35:1, with a maximum ratio of about 40:1. If the composition is formed into a cast sheet, the minimum ratio is about 3:1, the preferred ratio is about 8:1, and the maximum ratio is about 10:1.Type: GrantFiled: April 16, 1993Date of Patent: May 16, 1995Assignee: R. J. Reynolds Tobacco CompanyInventors: William J. Casey, III, Jeffery S. Gentry, Alvaro Gonzalez-Parra, Aju N. Lekwauwa, Dennis M. Riggs, Gary R. Shelar, Kenneth W. Swicegood, Ronald O.

Patent number: 5271419Abstract: A cigarette includes a charge or roll of smokable material (e.g., tobacco cut filler) circumscribed by two layers of paper wrapping materials. The first or inner wrapping material includes an inorganic filler material and tobacco material within the web. The inner wrapping material also can include a water soluble salt burn chemical and a carbonaceous material within the web. The second or outer wrapping material circumscribes and overwraps the first wrapping material, has a cellulosic base web and inorganic filler material, and exhibits a low inherent air permeability. The outer wrapping material can include a magnesium hydroxide filler, and exhibits an inherent air permeability of below about 15 CORESTA units and a net air permeability above about 40 CORESTA units. The cigarette is capable of sustaining smolder under FTC smoking conditions while yielding very low levels of visible sidestream smoke.Type: GrantFiled: September 13, 1991Date of Patent: December 21, 1993Assignee: R.

Patent number: 4991596Abstract: A smoking article includes a short, combustible, carbonaceous fuel element in a heat exchange relationship with a substrate carrying glycerin, tobacco extract, and a portion of an essential oil gland bearing plant. For example, fragments of cinnamon bark, lovage root, chamomile flowers or cardamon physically separate from the fuel element provide for a controlled release of a flavor profile during use of the smoking article. Heat provided by the burning fuel element acts to release essential oils from the glands to provide a complex flavor and aroma profile. The smoking article is capable of providing the user with many of the pleasures of smoking by heating but not necessarily burning tobacco.Type: GrantFiled: July 11, 1989Date of Patent: February 12, 1991Assignee: R. J. Reynolds Tobacco CompanyInventors: Brian M. Lawrence, Milly M. L. Wong, Thomas A. Perfetti, Thomas L. Gentry, Alvaro Gonzalez-Parra, Jerry W. Lawson, Gary R. Shelar, Gary W. Worrell
