Heated tobacco product

Abstract

Provided is a feature for a heated tobacco product having a tobacco rod formed by filling the inside of wrapping paper with a tobacco filler containing a tobacco raw material and an aerosol-source material, that prevents damage to an electric heater, such as bending or curving, during insertion into the tobacco rod, prevents the tobacco filler constituting the tobacco rod from being pressed toward the mouth end, and prevents the tobacco rod from deforming by buckling. This heated tobacco product has a tobacco rod formed by filling the inside of wrapping paper with a tobacco filler containing cut tobacco and an aerosol-source material, and is provided with a heater-insertion cavity that is open on the distal end surface side of the tobacco rod and extends in the axial direction of the tobacco rod, and into which a heater of a heating device is inserted.

1 . A heated tobacco product, the heated tobacco product having a tobacco rod formed by filling a space inside wrapping paper with a tobacco filler, the tobacco filler including a tobacco raw material and an aerosol-source material, the heated tobacco product comprising
 a heater-insertion cavity that receives a heater inserted into the heater-insertion cavity, the heater being a heater of a heating device, the heater-insertion cavity being open near a distal end face of the tobacco rod and extending in an axial direction of the tobacco rod.   
     
     
         2 . The heated tobacco product according to  claim 1 , wherein the heater-insertion cavity has a cross-sectional area orthogonal to the axial direction of the tobacco rod that is smaller than a cross-sectional area at corresponding opposed locations of the heater inserted into the tobacco rod to a specified depth. 
     
     
         3 . The heated tobacco product according to  claim 2 , wherein the heater-insertion cavity has a cross-sectional area orthogonal to the axial direction of the tobacco rod that is set within a range of greater than or equal to 70% and less than or equal to 99% of a cross-sectional area at corresponding opposed locations of the heater inserted into the tobacco rod to a specified depth. 
     
     
         4 . The heated tobacco product according to  claim 1 , wherein the heater-insertion cavity has a shape of a circular cylinder with a diameter of greater than or equal to 1 mm and less than or equal to 4 mm. 
     
     
         5 . The heated tobacco product according to  claim 1 , wherein the heater-insertion cavity has a shape of a circular cone that tapers down in the axial direction of the tobacco rod, the heater-insertion cavity having a diameter of greater than or equal to 1 mm and less than or equal to 4 mm at a first end located near the distal end face of the tobacco rod, the heater-insertion cavity having a diameter of greater than 0 mm and less than or equal to 0.5 mm at a second end located opposite to the distal end face. 
     
     
         6 . The heated tobacco product according to  claim 1 , wherein the heater-insertion cavity has a shape of a circular cone frustum that tapers down in the axial direction of the tobacco rod, the heater-insertion cavity having a diameter of greater than or equal to 1 mm and less than or equal to 4 mm at a first end located near the distal end face of the tobacco rod, the heater-insertion cavity having a diameter of greater than or equal to 0.5 mm and less than or equal to 3.5 mm at a second end located opposite to the distal end face. 
     
     
         7 . The heated tobacco product according to  claim 1 ,
 wherein the heated tobacco product has a filter coaxially coupled to a portion of the tobacco rod located near a proximal end of the tobacco rod, and   wherein the filter includes a cooling part to cool a volatile substance, the volatile substance being released from the aerosol-source material included in the tobacco filler.   
     
     
         8 . The heated tobacco product according to  claim 7 , wherein the filter includes a support part, the support part being disposed at a connection end of the filter to prevent or inhibit the tobacco filler from being pushed toward a mouth end of the filter upon insertion of the heater into the heater-insertion cavity, the connection end being an end connected to a portion of the tobacco rod located near the proximal end of the tobacco rod. 
     
     
         9 . The heated tobacco product according to  claim 8 , wherein the filter includes a mouthpiece part disposed near the mouth end of the filter. 
     
     
         10 . The heated tobacco product according to  claim 1 , wherein the heater-insertion cavity is formed as a through-hole that penetrates the tobacco rod. 
     
     
         11 . The heated tobacco product according to  claim 1 , wherein the heater-insertion cavity is formed as a recess that does not penetrate the tobacco rod.
