  • the diameter (cross-sectional area) of the heater-insertion cavity 23 A according to the first modification is set within a range of greater than or equal to 70% and less than or equal to 99% of the diameter (cross-sectional area) of the electric heater 103 A. This makes it possible to meet the above-mentioned requirements regarding both the resistance encountered during insertion of the electric heater 103 A, and the proper contact after the insertion. This results in both improved usability in attaching the tobacco rod 2 to the heating device 100 (in inserting the electric heater 103 A into the tobacco rod 2 ), and improved heating efficiency in heating the tobacco filler 21 with the electric heater 103 A.
  • the heater-insertion cavity 23 A has the shape of a circular cylinder with a constant diameter as described above. This helps to ensure that, during heating with the heater, the tobacco filler 21 around the heater-insertion cavity 23 A can be sufficiently heated even at a location near the second end 23 b . This makes it possible to, during heating with the heater, prevent or inhibit creation of a temperature distribution within the tobacco filler 21 along the central axis CL 1 . This leads to increased aerosol delivery or improved stability of delivery.
  • the heater-insertion cavity 23 A according to the first modification is preferably formed in the shape of a circular cylinder with a diameter of greater than or equal to 1 mm and less than or equal to 4 mm.
  • the heater-insertion cavity 23 A preferably has a diameter that is greater than or equal to 10% and less than or equal to 80% of the diameter of the tobacco rod 2 .
  • the heater-insertion cavity 23 A preferably has a diameter of about 2.5 mm.
  • FIG. 7 illustrates the tobacco rod 2 (tobacco filler 21 ) according to a second modification.
  • the tobacco rod 2 according to the second modification has a heater-insertion cavity 23 B in the shape of a circular cone frustum (circular truncated cone) that tapers down along the central axis CL 1 of the tobacco rod 2 .
  • FIG. 8 illustrates the tobacco rod 2 according to the second modification when attached into the accommodating cavity 107 of the heating device 100 .
  • FIG. 8 depicts an electric heater 103 B inserted into the tobacco rod 2 to a specified depth.
  • the electric heater 103 B according to the second modification has the shape of a circular cone frustum (circular truncated cone).
  • the diameter of the heater-insertion cavity 23 B may be set to a value smaller than the diameter (cross-sectional area) at corresponding opposed locations of the electric heater 103 B inserted into the tobacco rod 2 to a specified depth.
  • the electric heater 103 B forces the heater-insertion cavity 23 B to spread apart as the electric heater 103 B is inserted into the heater-insertion cavity 23 B. This allows for tight contact between the tobacco filler 21 , which laterally surrounds the heater-insertion cavity 23 B, and the electric heater 103 B. This results in improved efficiency of heat conduction from the electric heater 103 B to the tobacco filler 21 .
  • the heater-insertion cavity 23 B has a diameter (cross-sectional area) that is set within a range of greater than or equal to 70% and less than or equal to 99% of the diameter (cross-sectional area) at corresponding opposed locations of the electric heater 103 B inserted into the tobacco rod 2 to a specified depth.
  • the heater-insertion cavity 23 B according to the second modification is designed to have the shape of a circular cone frustum (circular truncated cone). This makes it possible to achieve both the advantage of using the heater-insertion cavity 23 designed to have the shape of a circular cone, and the advantage of using the heater-insertion cavity 23 designed to have the shape of a circular cylinder.
  • the heater-insertion cavity 23 B according to the second modification tends to have a diameter at the second end 23 b near the mouth end that is greater than the diameter of the corresponding portion of the heater-insertion cavity 23 designed to have the shape of a circular cone. This helps to ensure that during heating with the heater, a temperature distribution is less likely to occur within the tobacco filler 21 along the central axis CL 1 . Further, the heater-insertion cavity 23 B according to the second modification has a diameter (cross-sectional area) that tapers down along the central axis CL 1 of the tobacco rod 2 . This makes it possible to reduce the resistance encountered during insertion of the electric heater 103 B into the tobacco rod 2 and, at the same time, ensure improved contact after the insertion.
  • the heater-insertion cavity 23 B preferably has a diameter of greater than or equal to 1 mm and less than or equal to 4 mm at the first end 23 a , which is located near the distal end face 2 a of the tobacco rod 2 , and a diameter of greater than or equal to 0.5 mm and less than or equal to 3.5 mm at the second end 23 b , which is located opposite to the distal end face 2 a .
  • the heater-insertion cavity 23 B preferably has a diameter at the first end 23 a located near the distal end face 2 a of the tobacco rod 2 that is greater than or equal to 10% and less than or equal to 80% of the diameter of the tobacco rod 2 , and has a diameter at the second end 23 b that is greater than or equal to 5% and less than or equal to 70% of the diameter of the tobacco rod 2 .
  • the heater-insertion cavity 23 , 23 A, or 23 B of the tobacco rod 2 (tobacco filler 21 ) according to Embodiment 1 may not necessarily have the shape of a circular cone, a circular cylinder, or a circular cone frustum as described above but may have various other shapes.
  • the number of heater-insertion cavities 23 , 23 A, or 23 B to be provided in the tobacco rod 2 (tobacco filler 21 ) is not particularly limited.
  • the tobacco rod 2 (tobacco filler 21 ) may have a plurality of heater-insertion cavities 23 , 23 A, or 23 B.
  • FIG. 9A illustrates a heater-insertion cavity 23 C according to a third modification.
  • the heater-insertion cavity 23 C according to the third modification is identical to the heater-insertion cavity 23 illustrated in FIG. 2 , except that the heater-insertion cavity 23 C has the shape of a circular cone formed as a through-hole that penetrates the tobacco rod 2 .
  • FIG. 9B illustrates a heater-insertion cavity 23 D according to a fourth modification.
  • the heater-insertion cavity 23 D according to the fourth modification is identical to the heater-insertion cavity 23 A illustrated in FIG. 5 , except that the heater-insertion cavity 23 D has the shape of a circular cylinder formed as a through-hole that penetrates the tobacco rod 2 .
  • FIG. 9C illustrates a heater-insertion cavity 23 E according to a fifth modification.
  • the heater-insertion cavity 23 E according to the fifth modification is identical to the heater-insertion cavity 23 B illustrated in FIG. 7 , except that the heater-insertion cavity 23 E has the shape of a circular cone frustum formed as a through-hole that penetrates the tobacco rod 2 .
  • the tobacco rod 2 may preferably be connected integrally to the filter 3 by means of a filter-tip attachment device after the heater-insertion cavity 23 C, 23 D, or 23 E is formed in the tobacco rod 2 .
  • Forming the heater-insertion cavity 23 C, 23 D, or 23 E as a through-hole penetrating the tobacco rod 2 as illustrated in FIGS. 9A to 9C ensures that no tobacco filler 21 exists downstream of the distal end of the electric heater 103 , which in turn ensures that no decrease in thermal conductivity occurs during heating with the heater. This helps to prevent or inhibit an aerosol generated during heating with the heater from being cooled to condense by a portion of the tobacco filler 21 located near the distal end of the electric heater 103 . This results in increased aerosol delivery during use.
  • forming the heater-insertion cavity 23 , 23 A, or 23 B as a non-through hole that does not penetrate the tobacco rod 2 as illustrated in FIGS. 2, 5 , and 7 ensures that, for example, in forming the heater-insertion cavity 23 , 23 A, or 23 B by use of a needle inserted through the distal end face 2 a of the tobacco rod 2 , the tobacco filler 21 of the tobacco rod 2 is not pushed out by the needle toward the mouth end.
  • the heated tobacco product according to the present invention is not limited to the embodiments described above.
