Abstract

An aerosol-generating article is provided, including: a rod of aerosol-generating substrate, the aerosol-generating substrate including a tobacco material having a bulk density of less than 350 milligrams per cubic centimetre; and a downstream section provided downstream of the rod of aerosol-generating substrate, the downstream section including a hollow tubular element abutting a downstream end of the rod of aerosol-generating substrate, and the downstream section having a length of at least 40 millimetres.

Claims

exact text as granted — not AI-modified
1 .- 15 . (canceled) 
     
     
         16 . An aerosol-generating article, comprising:
 a rod of aerosol-generating substrate, wherein the aerosol-generating substrate comprises a tobacco material having a bulk density of less than 350 milligrams per cubic centimetre; and   a downstream section provided downstream of the rod of aerosol-generating substrate, the downstream section comprising a hollow tubular element abutting a downstream end of the rod of aerosol-generating substrate, and the downstream section having a length of at least 40 millimetres.   
     
     
         17 . The aerosol-generating article according to  claim 16 , wherein the rod of aerosol-generating substrate has a length of at least 17 millimetres. 
     
     
         18 . The aerosol-generating article according to  claim 16 , wherein the tobacco material has an average density of less than 300 milligrams per cubic centimetre. 
     
     
         19 . The aerosol-generating article according to  claim 16 , wherein the tobacco material has an average density of at least 100 milligrams per cubic centimetre. 
     
     
         20 . The aerosol-generating article according to  claim 16 , wherein a ratio of the length of the rod of aerosol-generating substrate to the total length of the aerosol-generating article is at least 0.2. 
     
     
         21 . The aerosol-generating article according to  claim 16 , wherein a ratio of the length of the rod of aerosol-generating substrate to the total length of the aerosol-generating article is at least 0.25. 
     
     
         22 . The aerosol-generating article according to  claim 16 , wherein the rod of aerosol-generating substrate has a length of less than 30 millimetres. 
     
     
         23 . The aerosol-generating article according to  claim 16 , wherein a length of the downstream section is at least 45 millimetres. 
     
     
         24 . The aerosol-generating article according to  claim 16 , wherein the rod of aerosol-generating substrate has a length of at least 20 millimetres. 
     
     
         25 . The aerosol-generating article according to  claim 16 , further comprising a ventilation zone at a location along the hollow tubular element of the downstream section. 
     
     
         26 . The aerosol-generating article according to  claim 16 , wherein a wall thickness of the hollow tubular element of the downstream section is less than 0.5 millimetre. 
     
     
         27 . The aerosol-generating article according to  claim 16 , wherein a ratio of a length of the hollow tubular element of the downstream section to a length of the rod of aerosol-generating substrate is at least 1.5. 
     
     
         28 . The aerosol-generating article according to  claim 16 , wherein a ratio of a length of the hollow tubular element of the downstream section to a total length of the aerosol-generating article is at least 0.5. 
     
     
         29 . The aerosol-generating article according to  claim 16 , wherein a length of the hollow tubular element is at least 25 millimetres. 
     
     
         30 . The aerosol-generating article according to  claim 16 , wherein a length of the hollow tubular element is at least 45 millimetres. 
     
     
         31 . The aerosol-generating article according to  claim 16 , wherein the aerosol-generating substrate comprises a shredded tobacco material.
