  • Patent number: 5538020
    Abstract: Electrochemical heat sources, materials used to make electrochemical heat sources and methods of forming electrochemical heat sources are disclosed. The electrochemical heat sources includes at least two metallic agents capable of interacting electrochemically with one another, such as magnesium and iron or nickel. The metallic agents may be provided in a variety of forms, including a frozen melt, a bimetallic foil, wire of a first metal wrapped around strands of a different metal, and a mechanical alloy. The metallic agents may be in the form of a powder filling a straw, or small particles extruded with a binder or pressed to form a rod. The powder filled straw or rod may be placed in a heat chamber surrounded by tobacco in a smoking article. An electrolyte solution contacts the metallic agents in the heat chamber to initiate the electrochemical interaction, generating heat which in turn may be used to volatilize nicotine and flavor materials in the tobacco.

  • Patent number: 5285798
    Abstract: A smoking article with an electrochemical heat source is disclosed. The non-combustion heat source includes at least two metallic agents capable of interacting electrochemically with one another, such as magnesium and iron or nickel. The metallic agents may be provided in a variety of forms, including a frozen melt, a bimetallic foil, wire of a first metal wrapped around strands of a different metal, and a mechanical alloy. The metallic agents may be in the form of a powder filling a straw, or small particles extruded with a binder or pressed to form a rod. Preferably, the heat source is self-extinguishing if ignited. The powder filled straw or rod may be placed in a heat chamber surrounded by tobacco. An electrolyte solution contacts the metallic agents in the heat chamber to initiate the electrochemical interaction, generating heat which in turn volatilizes the nicotine and flavor materials in the tobacco.

  • Patent number: 5235992
    Abstract: Processes for producing flavor substances from tobacco are disclosed. The processes involve heating tobacco during a first staged heating to a first toasting temperature to drive off volatile materials; increasing the toasting temperature during a second staged heating to a second toasting temperature and separately collecting, as flavor substances, at least portions of the volatile materials driven off at the first and second toasting temperatures.Another aspect of the present invention involves reducing the moisture content of the tobacco without removing volatile flavor components, such as by freeze drying the tobacco, and then heating the dried tobacco.Preferably the tobacco is heated in a flowing gas stream and at least portions of the volatile materials are separately collected as flavor substances as the gas stream passes sequentially through a moderate temperature trap, a cold temperature trap and a filter capable of collecting submicron sized particles.

  • Patent number: 5119834
    Abstract: The present invention is directed to a smoking article which produces an aerosol that resembles tobacco smoke but which preferably contains no more than a minimal amount of incomplete combustion or pyrolysis products. The preferred smoking article of the present invention provides an aerosol "smoke" which is chemically simple, consisting essentially of air, oxides of carbon, water, and the aerosol which carries any desired flavor or other desired volatile materials as well as trace amounts of other materials. In addition to a mouthend piece, an especially preferred embodiment of the present smoking article comprises a short combustible carbonaceous fuel element which is less than about 30 mm in length prior to smoking. The fuel element is disposed longitudinally relative to a physically separate aerosol generating means which comprises a porous nonparticulate substrate. The substrate includes one or more aerosol forming substances.

  • Patent number: 5105831
    Abstract: The present invention is directed to a smoking article which is 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.Preferred embodiments of the present smoking article comprises a short combustible carbonaceous fuel element, a short heat stable, preferably carbonaceous substrate bearing an aerosol forming substance and disposed longitudinally behind the fuel element, an efficient insulating means, and a relatively long mouthend piece. Preferably, the fuel element is provided with a plurality of longitudinally extending passageways which act to control the heat transferred from the burning fuel element to the aerosol generating means, thus preventing the thermal degradation of the aerosol former.

  • Patent number: 4955399
    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.

  • Patent number: 4655229
    Abstract: A device for delivering flavor utilizing a flavor carrier in powdered form. A preferred embodiment of the system may resemble a conventional cigarette, and includes an overwrap defining a path of airflow through the device, a chamber containing particulate matter, and a means for entraining the particulate matter in the airflow. The overwrap may be a tube, resembling a conventional cigarette in appearance, feel, and draft. A means for entraining the particulate matter may be an intake flow limiter having a passage therein which causes a thin stream of high-velocity air to impinge upon the particulate matter, entraining it in the airflow. Alternately, the entraining means may be a series of baffles or similar components which produce a turbulent airflow, thus entraining the particulate matter. Output means are also provided for eliminating stoppages and for delivering the airflow, with particulate matter entrained therein, to the user.
