Non-combustion-heating-type stick

Abstract

A non-combustion-heating-type stick comprising: a substrate that includes an aerosol source; a cooling portion that produces an aerosol by cooling a vapor produced by heating the substrate; and a filter portion that is disposed in an area through which the aerosol passes, wherein at least one of the substrate, the cooling portion, and the filter portion contains a porous adsorbent.

1 . A non-combustion-heating-type stick comprising:
 a substrate that includes an aerosol source;   a cooling portion that generates an aerosol by cooling vapor generated as a result of heating the substrate; and   a filter portion disposed in an area through which the aerosol passes, wherein   at least any one of the substrate, the cooling portion, and the filter portion contains a porous adsorbent.   
     
     
         2 . The non-combustion-heating-type stick according to  claim 1 , wherein the porous adsorbent is activated carbon. 
     
     
         3 . The non-combustion-heating-type stick according to  claim 2 , wherein
 in the activated carbon, a ratio of a pore volume of a pore size greater than or equal to 50 nm and less than or equal to 5000 nm to a total pore volume of a pore size less than or equal to 5000 nm is higher than or equal to 15%.   
     
     
         4 . The non-combustion-heating-type stick according to  claim 2 , wherein
 in the activated carbon, a pore volume of a pore size greater than or equal to 50 nm and less than or equal to 5000 nm is greater than or equal to 0.2 cm 3 /g and less than or equal to 0.9 cm 3 /g.   
     
     
         5 . The non-combustion-heating-type stick according to  claim 2 , wherein
 in the activated carbon, a ratio of a pore volume of a pore size less than 2 nm to a total pore volume of a pore size less than or equal to 5000 nm is lower than or equal to 70%.   
     
     
         6 . The non-combustion-heating-type stick according to  claim 2 , wherein
 a BET specific surface area of the activated carbon is greater than or equal to 600 m 2 /g and less than or equal to 1800 m 2 /g.   
     
     
         7 . The non-combustion-heating-type stick according to  claim 1 , wherein
 the porous adsorbent is disposed in a place where the porous adsorbent contacts with the aerosol in the stick.   
     
     
         8 . The non-combustion-heating-type stick according to  claim 7 , wherein
 the porous adsorbent is present at any one or more of the following locations 1) to 5),   1) in a filter of the filter portion,   2) in a paper layer of a wrapping paper wrapping the filter or a surface opposed to the filter,   3) in a hollow part of the filter portion,   4) a surface facing the hollow part, and   5) in a cavity formed between adjacent segments of a plurality of segments of the filter.   
     
     
         9 . A non-combustion-heating-type stick comprising:
 a substrate that includes an aerosol source; and   a filter portion disposed in an area through which an aerosol generated as a result of heating the substrate passes, wherein   at least any one of the substrate and the filter portion contains activated carbon in which a ratio of a pore volume of a pore size greater than or equal to 50 nm and less than or equal to 5000 nm to a total pore volume of a pore size less than or equal to 5000 nm is higher than or equal to 15%.
