  • Patent number: 5170807
    Abstract: There is disclosed a method of producing a non-burning wrapper for use with smoking products. A non-burning wrapper is formed by treating a base paper with a solution consisting essentially of water, calcium chloride and a reactive size for paper; drying the thus treated paper; coating one side of the thus treated base paper with a solution consisting essentially of water, calcium carbonate, potassium silicate and sodium carboxymethycellulose; and drying the thus treated and coated paper to form a non-burning wrapper for use with smoking products.

  • Patent number: 5105837
    Abstract: A wrapper for use in smoking articles such as cigarettes, and in particular, to a wrapper for smoking articles having a heat source, a physically separate aerosol generating means, and a mouthend piece. More specifically the invention relates to smoking articles which employ a substantially non-burnable paper used as an innerwrap and/or outerwrap which encircles at least a portion of the fuel element of such smoking articles.

  • Patent number: 4938238
    Abstract: The present invention relates to an improved wrapper for a smoking article haviing a combustible fuel element encircled by an insulating layer and a physically separate aerosol generating means as well as to smoking articles employing such wrappers. The wrapper encircles at least a portion of the insulating layer for the fuel element and comprises a permeable sheet material which during burning of the fuel provides a coherent layer to assist in controlling the amount of peripheral air to the fuel element during smoking.

  • Patent number: 4779631
    Abstract: A wrapper particularly useful for smoking articles of the type containing a burn fuel element and ceramic jacket. The wrapper includes an inner layer for surrounding the burn fuel element and jacket and an outer layer with the combination imparting controlled throttling properties. The inner layer may be a conventional cigarette wrapper material of cellulosic construction and having biased burned properties. The outer layer surrounds the inner sheet and preferably comprises cellulose fibers, titanium dioxide, attapulgite clay, high temperature resistant microfibers, and a burn enhancer. The outer wrapper also maintains permeability and pressure drop properties at temperatures in excess of 400.degree. C. while the inner wrapper burns out resulting in generally infinite permeability after burning.
