Abstract: Making an aerosol generating cartridge useful for a smoking article is described. The method comprises filling a non-combustible elongated capsule, open at one end, with a substrate bearing an aersol forming material, and applying a fuel element to the open end of the capsule to enclose the substrate within the capsule.

Abstract: The present invention preferably relates to an insulated smoking article which is capable of producing substantial quantities of smoke, both initially and over the useful life of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products or sidestream smoke. Thus, the article of the present invention is able to provide the user with the sensations and benefits of cigarette smoking without burning tobacco. In addition, the article may be made virtually ashless so that the user does not have to remove any ash during use.Preferred embodiments of the present smoking article comprise a short i.e.

Abstract: Processed smokable materials are provided by forming a slurry of combustible material (e.g., a carbonaceous material) in an aqueous liquid. The slurry then is contacted with a foaming agent which includes a mixture of a surfactant and a polymeric film-forming agent. The slurry is agitated to provide a slurry of decreased density. The slurry so provided then is formed into the desired shape and dried. The processed smokable material which results is useful as cut filler for cigarette manufacture.

Abstract: A cigarette provides tobacco flavor by heating tobacco, but not burning tobacco or any other material. A heat source which includes a metal oxide (e.g., calcium oxide), an anhydrous metal sulfate (e.g., magnesium sulfate), an inorganic salt and a sugar, generates heat upon contact of water therewith. The heat produced by the heat source heats tobacco in a heat exchange relationship therewith. Flavors volatilize from the tobacco and are drawn into the mouth of the user of the cigarette. Typical heat sources heat the tobacco to a temperature within 70.degree. C. to 200.degree. C. for 4 to 8 minutes.

Abstract: An aerosol delivery article provides flavor or a dose of a drug by heating a flavor or a drug, but not burning any material. A heat source which includes granular magnesium, granular iron, and finely divided cellulose generates heat upon contact thereof with an aqueous solution of potassium chloride. The heat source is in a heat exchange relationship with the flavor or drug. Heat generated by the heat source heats the flavor or drug in a controlled manner. The flavor or drug volatilizes and is drawn into the mouth of the user of the article. Typical heat sources heat the flavor or drug to a temperature within about 70.degree. C. to about 180.degree. C. for 4 to 8 minutes.

Abstract: A drug delivery article provides a dose of a volatilized drug by heating a drug carrying substrate, but not burning any material. A heat source which includes a metal oxide (e.g., calcium oxide), an anhydrous metal sulfate (e.g., magnesium sulfate), an inorganic salt and a sugar, generates heat upon contact of water therewith.

Abstract: The present invention relates to an aerosol producing substrate for subsequent use in smoking articles and to methods of preparing the aerosol producing substrate. Preferred smoking articles which employ the aerosol producing substrate of the present invention are capable of producing substantial quantities of aerosol, both initially and over the useful life of the product, without significant thermal degradation of the aerosol former and without the present of substantial pyrolysis or incomplete combustion products or sidestream aerosol. Thus, such smoking articles provide the user with the sensations and benefits of cigarette smoking without burning tobacco.

Abstract: The present invention relates to a smoking article which produces an aerosol that resembles tobacco smoke, but contains no more than a minimal amount of incomplete combustion or pyrolysis products.Preferred embodiments of the present smoking article comprise a short combustible carbonaceous fuel element, a heat stable substrate bearing an aerosol forming substance, a heat conducting member which contacts a portion of the fuel element and the substrate, and an insulating jacket surrounding at least a portion of the fuel element.The smoking article of the present invention is capable of providing an aerosol "smoke" which is chemically simple, consisting essentially of air, oxides of carbon, water, and the aerosol which carries any desired flavorants or other desired volatile materials, and trace amount of other materials. The aerosol "smoke" from the preferred embodiments has no significant mutagenic activity as measured by the Ames Test.

Abstract: The present invention relates to a substrate material having a decreased retentive capacity for use as a carrier for aerosol forming materials in smoking articles which smoking articles are capable of producing substantial quantities of aerosol, both initially and over the useful life of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products or sidestream aerosol. Thus, the substrate material of the present invention when used with preferred smoking articles is able to provide the user with the sensations and benefits of cigarette smoking without burning tobacco. In addition, the article may be made virtually ashless so that the user does not have to remove any ash during use.

Abstract: The present invention relates to a smoking article, preferably in cigarette form, which produces an aerosol that resembles tobacco smoke. The article preferably comprises a short combustible fuel element having a density greater than 0.5 g/cc, a separate substrate bearing an aerosol forming material, a heat conducting member recessed from the lighting end of the fuel element, which preferably encloses the substrate, a resilient insulating jacket encircling at least a portion of the fuel element, and an optional tobacco jacket encircling at least a portion of the aerosol forming material.
