Aerosol generation product

Abstract

An aerosol generation product according to one embodiment comprises: a medium segment filled with a medium; and a first segment arranged upstream of the medium segment and/or a second segment arranged downstream of the medium segment, wherein the first segment or the second segment is composed of a cellulose acetate filter comprising a plasticizer, and the amount of plasticizer can be set in a range at which no indentations are formed on the first segment or the second segment.

1 . An aerosol-generating article comprising:
 a medium segment filled with a medium; and   at least one of a first segment disposed upstream of the medium segment and a second segment disposed downstream of the medium segment;   wherein the first segment or the second segment comprises a cellulose acetate filter comprising a plasticizer, and   a content of the plasticizer is set to a range in which a recess in the first segment or the second segment does not occur.   
     
     
         2 . The aerosol-generating article of  claim 1 ,
 wherein the content of the plasticizer is substantially equal to 11% or less than 11%.   
     
     
         3 . The aerosol-generating article of  claim 2 ,
 wherein the content of the plasticizer is substantially equal to 4% or greater than 4%.   
     
     
         4 . The aerosol-generating article of  claim 3 ,
 wherein the plasticizer is one of triacetin (TA) or triethyl citrate (TEC).   
     
     
         5 . The aerosol-generating article of  claim 2 ,
 wherein the medium comprises at least one component of tobacco granules, reconstituted tobacco, and cut tobacco leaves or a combination thereof.   
     
     
         6 . The aerosol-generating article of  claim 5 ,
 wherein the medium is pH-treated and nicotine spread from the medium is adsorbed into the first segment or the second segment.   
     
     
         7 . The aerosol-generating article of  claim 6 ,
 wherein the medium is pH-treated to be in a range of 7.0 to 9.5.   
     
     
         8 . An aerosol-generating article comprising:
 a first segment; and   a second segment disposed downstream of the first segment,   wherein nicotine is adsorbed into the first segment or the second segment,   the first segment or the second segment comprises a cellulose acetate filter comprising a plasticizer, and   a content of the plasticizer is greater than or equal to 4% and less than or equal to 11%.   
     
     
         9 . The aerosol-generating article of  claim 8 , further comprising:
 a medium segment disposed between the first segment and the second segment,   wherein the medium segment comprises a pH-treated tobacco medium, and nicotine adsorbed into the first segment or nicotine adsorbed into the second segment is spread from the medium segment.   
     
     
         10 . The aerosol-generating article of  claim 8   wherein the first segment or the second segment is manufactured by cutting a filter portion to which free nicotine emitted from a medium raw material comprising nicotine is spread.
