Tobacco rod for flavor inhaler

Abstract

The present invention provides a tobacco rod for a flavor inhaler, including a plurality of rod-shaped segments connected to one another, in which each of the segments includes a cylindrical container and a flavor source including tobacco filled in the cylindrical container, the flavor source being filled in such a manner as to form, over a longitudinal direction, a channel for causing a flavor component to pass therethrough, and the channels of the segments are discontinuously connected at the connecting portion.

1 . A tobacco rod for a flavor inhaler, comprising a plurality of rod-shaped segments connected to one another,
 wherein each of the segments includes a cylindrical container and a flavor source including tobacco filled in the cylindrical container, the flavor source being filled in such a manner as to form, over a longitudinal direction, a channel for causing a flavor component to pass therethrough, and   the channels of the segments are discontinuously connected at the connecting portion.   
     
     
         2 . The tobacco rod according to  claim 1 , wherein the tobacco rod is for use in a direct heating type or indirect heating type flavor inhaler. 
     
     
         3 . The tobacco rod according to  claim 2 , wherein the flavor source comprises a surface-treated flavor generating sheet. 
     
     
         4 . The tobacco rod according to  claim 2 , wherein a side surface of the cylindrical container is made of a material selected from the group consisting of paper, a resin, a metal, and a combination thereof. 
     
     
         5 . The tobacco rod according to  claim 2 , wherein the side surface of the cylindrical container has a multilayer structure. 
     
     
         6 . The tobacco rod according to  claim 2 . wherein the side surface of the cylindrical container has a permeability of less than 1 coresta unit. 
     
     
         7 . The tobacco rod according to  claim 2 , wherein the flavor source comprises a plurality of strip-shaped flavor generating sheets, and a longitudinal direction of the sheets is substantially parallel to the longitudinal direction of the cylindrical container. 
     
     
         8 . The tobacco rod according to  claim 2 . wherein the flavor source comprises an aerosol source that generates aerosol. 
     
     
         9 . A method for producing the tobacco rod according to  claim 1 , comprising:
 a step of providing a precursor including a cylindrical container and a flavor source including tobacco filled in the cylindrical container, the flavor source being filled in such a manner as to form, over a longitudinal direction, a channel for causing a flavor component to pass therethrough;   a step of preparing two or more of the segments by cutting the precursor in a direction vertical to the longitudinal direction; and   a step of rotating one or more of the segments in a circumferential direction around a longitudinal direction axis.   
     
     
         10 . A direct heating type or indirect heating type flavor inhaler, comprising the tobacco rod according to  claim 1 . 
     
     
         11 . The flavor inhaler according to  claim 10 , further comprising an aerosol source that generates aerosol on an upstream side of the tobacco rod. 
     
     
         12 . An ultrasonic vibration type flavor inhaler, comprising the tobacco rod according to  claim 1 . 
     
     
         13 . The tobacco rod according to  claim 3 , wherein a side surface of the cylindrical container is made of a material selected from the group consisting of paper, a resin, a metal, and a combination thereof. 
     
     
         14 . The tobacco rod according to  claim 3 , wherein the side surface of the cylindrical container has a multilayer structure. 
     
     
         15 . The tobacco rod according to  claim 4 , wherein the side surface of the cylindrical container has a multilayer structure. 
     
     
         16 . The tobacco rod according to  claim 3 , wherein the side surface of the cylindrical container has a permeability of less than 1 coresta unit. 
     
     
         17 . The tobacco rod according to  claim 4 , wherein the side surface of the cylindrical container has a permeability of less than 1 coresta unit. 
     
     
         18 . The tobacco rod according to  claim 5 , wherein the side surface of the cylindrical container has a permeability of less than 1 coresta unit. 
     
     
         19 . The tobacco rod according to  claim 3 , wherein the flavor source comprises a plurality of strip-shaped flavor generating sheets, and a longitudinal direction of the sheets is substantially parallel to the longitudinal direction of the cylindrical container. 
     
     
         20 . The tobacco rod according to  claim 4 , wherein the flavor source comprises a plurality of strip-shaped flavor generating sheets, and a longitudinal direction of the sheets is substantially parallel to the longitudinal direction of the cylindrical container.
