Aerosol-generating article

Abstract

An aerosol-generating article according to one aspect of the present disclosure may include a tobacco medium portion, a filter portion disposed to be spaced apart from the tobacco medium portion, and a tubular cooling portion disposed between the tobacco medium portion and the filter portion. A tobacco medium may be included in a wall constituting the cooling portion.

1 . An aerosol-generating article comprising:
 a tobacco medium portion;   a filter portion disposed to be spaced apart from the tobacco medium portion; and   a tubular cooling portion disposed between the tobacco medium portion and the filter portion, wherein the tubular cooling portion comprises a wall comprising a tobacco medium.   
     
     
         2 . The aerosol-generating article of  claim 1 , wherein the tobacco medium is uniformly disposed in the tubular cooling portion along a longitudinal direction of the tubular cooling portion. 
     
     
         3 . The aerosol-generating article of  claim 1 , wherein the tobacco medium is non-uniformly disposed in the tubular cooling portion along a longitudinal direction of the tubular cooling portion. 
     
     
         4 . The aerosol-generating article of  claim 3 , wherein a concentration of the tobacco medium in the tubular cooling portion at an inlet side of the tubular cooling portion adjacent to the tobacco medium portion is greater than at an outlet side of the tubular cooling portion adjacent to the filter portion. 
     
     
         5 . The aerosol-generating article of  claim 3 , wherein a concentration of the tobacco medium in the tubular cooling portion at an inlet side of the tubular cooling portion adjacent to the tobacco medium portion is less than at an outlet side of the tubular cooling portion adjacent to the filter portion. 
     
     
         6 . The aerosol-generating article of  claim 3 , wherein a concentration of the tobacco medium at a central region of the tubular cooling portion is greater than at opposite end regions of the tubular cooling portion. 
     
     
         7 . The aerosol-generating article of  claim 3 , wherein a concentration of the tobacco medium at a central region of the tubular cooling portion is less than at opposite end regions of the tubular cooling portion. 
     
     
         8 . The aerosol-generating article of  claim 1 , wherein the tubular cooling portion comprises a cellulose acetate tow. 
     
     
         9 . The aerosol-generating article of  claim 8 , wherein the cellulose acetate tow has a denier of 3 to 20. 
     
     
         10 . The aerosol-generating article of  claim 1 , wherein the wall comprises a flavoring material constituting the tubular cooling portion. 
     
     
         11 . The aerosol-generating article of  claim 1 , wherein the tobacco medium of the tubular cooling portion is in a form of granules. 
     
     
         12 . The aerosol-generating article of  claim 11 , wherein the tobacco medium portion comprises tobacco medium in the form of granules, wherein the granules of the tobacco medium of the tobacco medium portion are larger than the granules of the tubular cooling portion. 
     
     
         13 . The aerosol-generating article of  claim 1 , wherein the tobacco medium portion comprises a plurality of segments. 
     
     
         14 . The aerosol-generating article of  claim 13 , wherein at least one of the plurality of segments comprises a tobacco medium.
