Abstract

A flavor source-containing rod includes: a cap member at a tip end that is opposite of a mouthpiece end; and a flavor source-filled object downstream of the cap member. The cap member includes a natural fiber-containing sheet and the sheet is disposed such that a main surface thereof is roughly parallel to the longitudinal direction of the flavor source-containing rod.

         4 . The flavor source-containing rod according to  claim 3 , wherein the sheet is a dry-laid nonwoven fabric; and a compression rate (A) of the dry-laid nonwoven fabric filled inside the wrapper, the compression rate (A) being calculated using a method below, is 20% or more and less than 100%,
 {Method for Calculating Compression Rate (A)}
 Cross-sectional area (A1): a cross-sectional area of the dry-laid nonwoven fabric perpendicular to an axial direction of the cap member, which is measured after the wrapper has been removed from the cap member and the dry-laid nonwoven fabric has been taken from the cap member, 
 Cross-sectional area (A2): a cross-sectional area of an inside of the cap member perpendicular to the axial direction of the cap member,
   Compression rate ( A )(%)=(Cross-sectional area ( A 2)/Cross-sectional area ( A 1))×100.
 
 
   
     
     
         5 . The flavor source-containing rod according to  claim 3 , wherein the sheet is a dry-laid nonwoven fabric; and a plurality of layers of the dry-laid nonwoven fabric are filled inside the wrapper in a compressed state while stacked on top of one another and folded in an S-like shape. 
     
     
         6 . The flavor source-containing rod according to  claim 3 , wherein the sheet is a dry-laid nonwoven fabric that has been subjected to a gathering process:
 a layer of the gathered dry-laid nonwoven fabric is filled inside the wrapper while folded or a plurality of layers of the gathered dry-laid nonwoven fabric are filled inside the wrapper while stacked on top of one another and folded; and a ridge line formed by the gathering process is substantially parallel to an axial direction of the cap member.   
     
     
         7 . The flavor source-containing rod according to  claim 2 , wherein a gap is not visually identified between layers of the dry-laid nonwoven fabric at an end surface of the cap member in an axial direction of the cap member. 
     
     
         8 . The flavor source-containing rod according to  claim 2 , wherein the sheet is a wet-laid nonwoven fabric; and a volume occupancy (X) of the wet-laid nonwoven fabric filled inside the wrapper, the volume occupancy (X) being calculated using a method below, is 10% or more and less than 60%,
 {Method for Calculating Volume Occupancy (X)}
 Cross-sectional area (X1): a total area of the wet-laid nonwoven fabric in a cross section of the cap member perpendicular to an axial direction of the cap member, 
 Cross-sectional area (X2): a cross-sectional area of the inside of the cap member in a cross section of the cap member perpendicular to the axial direction of the cap member,
   Volume occupancy ( X )(%)=(Cross-sectional area ( X 1)/Cross-sectional area ( X 2))×100.
 
 
   
     
     
         9 . The flavor source-containing rod according to  claim 2 , wherein the sheet is a wet-laid nonwoven fabric that has been subjected to a gathering process;
 a layer of the gathered wet-laid nonwoven fabric is filled inside the wrapper while folded; and a ridge line formed by the gathering process is substantially parallel to an axial direction of the cap member.   
     
     
         10 . The flavor source-containing rod according to  claim 1 , wherein the natural fiber is at least one fiber selected from the group consisting of silk, wool, cotton, hemp, and a plant pulp. 
     
     
         11 . The flavor source-containing rod according to  claim 10 , wherein the natural fiber is a plant pulp. 
     
     
         12 . The flavor source-containing rod according to  claim 1 , wherein the cap member has an airflow resistance of 2 to 30 mmH 2 O. 
     
     
         13 . The flavor source-containing rod according to  claim 1 , further comprising another cap member disposed downstream of the flavor source filler. 
     
     
         14 . The flavor source-containing rod according to  claim 1 , wherein the flavor source filler includes shredded tobacco, a tobacco sheet, or tobacco granules.
