  • Patent number: 5415186
    Abstract: 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.

  • Patent number: 4759380
    Abstract: Filter cigarettes can be manufactured in a highly cost effective manner. Filter cigarettes include a tobacco rod having two segments of smokable material. The first segment is positioned at the lighting end of the cigarette and includes expensive, normally high quality tobaccos. The second segment is positioned at the filter end of the rod and includes cost effective smokable materials. A cellulose acetate filter element is axially aligned with the rod and is positioned adjacent to the second segment. Tipping material attaches the filter element to the tobacco rod. The second segment extends along the rod up to about 20 mm past the foremost point which the tipping material extends. The combined longitudinal length of the filter element and the second segment extends up to about 60 percent of the total length of the smoking article.
