摘要：
A heated aerosol-generating article (10) for use with an aerosol- generating device is designed to be difficult to light in the manner of traditional cigarettes. The heated aerosol-generating article (10) comprises a plurality of components, including an aerosol-forming substrate (20), assembled within a wrapper (60) to form a rod having a mouth end (70) and a distal end (80) upstream from the mouth end (70). The heated aerosol-generating article (10) defines a first air-flow path in which air drawn into the aerosol-generating article (10) through the mouth end (70) passes through the aerosol-forming substrate (20), and a second air-flow path in which air drawn into the aerosol-generating article (10) through the mouth end (70) does not pass through the aerosol-forming substrate (20). The resistance to draw (RTD) of the second air-flow path is lower than the RTD of the first air-flow path when the heated aerosol-generating article (10) is not coupled to an aerosol-generating device. As a result, the restricted air-flow through the aerosol-forming substrate makes it difficult for a user to inadvertently light the heated aerosol-generating article (10).
