FIELD: aerosol generating systems.
SUBSTANCE: invention relates to an aerosol generating article containing an aerosol generating substrate and adapted to produce an inhalable aerosol when heated. The product (10), generating an aerosol, for obtaining an inhaled aerosol when heated, contains: a rod of a substrate (12) that generates an aerosol; mouthpiece segment (18), containing an insert of filter material and located in the direction of flow and aligned in the longitudinal direction with the rod (12); and a hollow tubular segment (16) between the stem (12) and the mouthpiece segment (18). The hollow tubular segment (16) is longitudinally aligned with the stem (12) and the mouthpiece segment (18) and forms a cavity extending along its entire length to the upstream end of the mouthpiece segment (18). The product (10) further comprises a ventilation zone (26) at a location along the hollow tubular segment. The aerosol generating substrate rod has a length of less than 40 mm. The equivalent inner diameter of the hollow tubular segment (16) at the location of the ventilation zone (26) is at least 5 mm. The rod (12) of the aerosol generating substrate contains at least an aerosol generating agent, wherein the content of the aerosol generating agent in the rod (12) is at least about 10% based on dry weight.
EFFECT: ensuring consistent satisfactory delivery of the aerosol to the consumer during use.
