Carbonaceous heat source composition for non-combustion type smoking article and non-combustion type smoking article

Abstract

A carbonaceous heat source composition for a non-combustion type smoking article according to the present invention includes carbon and 0.5 to 5% by weight of a polyhydric alcohol. Also, a non-combustion type smoking article according to the present invention is provided with such a heat source.

1 . A carbonaceous heat source composition for a non-combustion type smoking articles, comprising carbon and 0.5 to 5% by weight of a polyhydric alcohol. 
   
   
       2 . The carbonaceous heat source composition according to  claim 1 , wherein the amount of the polyhydric alcohol is 1.0 to 5% by weight. 
   
   
       3 . The carbonaceous heat source composition according to  claim 1 , wherein the polyhydric alcohol is glycerin or propylene glycol. 
   
   
       4 . The carbonaceous heat source composition according to  claim 1 , further comprising a binder. 
   
   
       5 . The carbonaceous heat source composition according to  claim 4 , wherein the binder is contained in an amount of 5 to 15% by weight. 
   
   
       6 . The carbonaceous heat source composition according to  claim 1 , further comprising calcium carbonate. 
   
   
       7 . The carbonaceous heat source composition according to  claim 6 , wherein the calcium carbonate is contained in an amount of 30 to 55% by weight. 
   
   
       8 . A non-combustion type smoking article comprising:
 an aerosol-generating section which generates aerosol by heating; and   a heat source provided at an end of the aerosol-generating section so as to be physically separated from the aerosol-generating section in order to heat the aerosol section without substantially combusting the aerosol section,   wherein the heat source is constituted of the carbonaceous heat source composition according to  claim 1 .
