SMOKING ARTICLE

摘要

A cigarette provides tobacco flavor by heating tobacco, but not burning tobacco or any other material. A heat source which includes a metal oxide (eg., calcium oxide), an anhydrous metal sulfate (eg., 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. Flavours 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.
