| 发明名称 | Combustible heat source for a smoking article | ||
| 摘要 | A combustible heat source (4) for a smoking article (2) comprises carbon and at least one ignition aid, wherein the ignition aid is present in an amount of at least 20 percent by dry weight of the combustible heat source. The combustible heat source (4) has a first portion and an opposed second portion. At least part (4b) of the combustible heat source (4) between the first portion and the second portion is wrapped in a combustion resistant wrapper (22) that is one or both of heat conducting and substantially oxygen impermeable. Upon ignition of the first portion of the combustible heat source (4), the second portion of the combustible heat source increases in temperature to a first temperature. During subsequent combustion of the combustible heat source (4), the second portion of the combustible heat source (4) maintains a second temperature lower than the first temperature. | ||

| 主权项 | 1. A combustible heat source for a smoking article comprising carbon and at least one ignition aid selected from the group consisting of metal nitrate salts having a thermal decomposition temperature of less than about 600° C., chlorates, peroxides, thermitic materials, intermetallic materials, magnesium, zirconium, and combinations thereof, wherein the at least one ignition aid is present in an amount of at least about 20 percent by dry weight of the combustible heat source, the combustible heat source comprising a first portion and an opposed second portion, wherein at least part of the combustible heat source between the first portion and the second portion is wrapped in a combustion resistant wrapper that is one or both of heat conducting and substantially oxygen impermeable, and wherein upon ignition of the first portion of the combustible heat source the second portion of the combustible heat source increases in temperature to a first temperature and wherein during subsequent combustion of the combustible heat source the second portion of the combustible heat source maintains a second temperature lower than the first temperature. | ||
