Smoking article

Abstract

A smoking article includes an aerosol generating rod, and a filter portion disposed adjacent to the aerosol generating rod. The filter portion includes a filter body, a capsule member, and an adhesive. The capsule member contains a flavorant inside and is embedded in the filter body. The adhesive bonds the filter body and the capsule member.

What is claimed is: 
     
         1 . A smoking article comprising:
 an aerosol generating rod; and   a filter portion disposed adjacent to the aerosol generating rod, the filter portion comprising:
 a filter body; 
 a capsule member that contains a flavorant inside and that is embedded in the filter body; and 
 an adhesive that bonds the filter body and the capsule member. 
   
     
     
         2 . The smoking article according to  claim 1 , wherein the adhesive is a thermoplastic resin. 
     
     
         3 . The smoking article according to  claim 1 , wherein the capsule member has a capsule shell which is formed of a hydrophilic material which is weakened by water absorption. 
     
     
         4 . The smoking article according to  claim 3 , wherein the capsule shell of the capsule member is formed of a material selected from starch, dextrin, polysaccharides, agar, gellan gum, gelatin, natural gelling agents, glycerin, sorbitol, calcium chloride, and mixtures thereof. 
     
     
         5 . The smoking article according to  claim 1 , wherein the adhesive is an aqueous dispersion adhesive. 
     
     
         6 . The smoking article according to  claim 1 , wherein the capsule member has a capsule shell formed of a resin material. 
     
     
         7 . The smoking article according to  claim 1 , wherein:
 the capsule member is positioned on or near a central axis of the filter portion, and   the adhesive extends linearly on or near the central axis of the filter portion along the central axis.   
     
     
         8 . The smoking article according to  claim 1 , wherein:
 the capsule member is positioned on or near the central axis of the filter portion, and   a part of the adhesive is located in a projected cross-section with respect to the direction of the central axis in the capsule member.   
     
     
         9 . The smoking article according to  claim 1 , wherein the adhesive comprises a flavorant. 
     
     
         10 . The smoking article according to  claim 1 , wherein the adhesive comprises a pigment. 
     
     
         11 . The smoking article according to  claim 1 , wherein the adhesive extends over an entire length of the filter portion. 
     
     
         12 . The smoking article according to  claim 1 , wherein the capsule member is positioned at a distance shorter than 15 mm from a mouthpiece end of the filter portion in a direction of the central axis of the filter portion toward the aerosol generating rod. 
     
     
         13 . The smoking article according to  claim 1 , further comprising at least one second filter portion at a position between the aerosol generating rod and the filter portion. 
     
     
         14 . The smoking article according to  claim 1 , further comprising electric heater configured to heat the aerosol generating rod.
