Abstract

A tobacco rod for a flavor inhaler includes a cylindrical container, and a flavor source including tobacco filled in the cylindrical container, in which the flavor source is filled in such a manner as to form voids over a longitudinal direction, and the following relationship is satisfied: S/T≤17%, wherein T represents an area of all voids present in a cross-section of the flavor source orthogonal to the longitudinal direction of the cylindrical container, and S represents a total area of voids each having an area of 800000 μm 2 or more in the cross-section.

First claim

The invention claimed is:

1. A tobacco rod for a flavor inhaler, comprising a cylindrical container, and a flavor source including tobacco filled in the cylindrical container,
wherein the flavor source is filled in such a manner as to form voids over a longitudinal direction, and the following relationship is satisfied:
S/T≤ 17%

wherein T represents an area of all voids present in a cross-section of the flavor source orthogonal to the longitudinal direction of the cylindrical container, and S represents a total area of voids each having an area of 800000 μm 2 or more in the cross-section.

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 a side surface of the cylindrical container has a multilayer structure.

6. The tobacco rod according to claim 2 , wherein a side surface of the cylindrical container has an 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 direct heating type or indirect heating type flavor inhaler, comprising the tobacco rod according to claim 1 .

10. The flavor inhaler according to claim 9 , further comprising an aerosol source that generates aerosol on an upstream side of the tobacco rod.

11. An ultrasonic vibration type flavor inhaler, comprising the tobacco rod according to claim 1 .

12. 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.

13. The tobacco rod according to claim 3 , wherein the side surface of the cylindrical container has a multilayer structure.

14. The tobacco rod according to claim 4 , wherein the side surface of the cylindrical container has a multilayer structure.

15. The tobacco rod according to claim 3 , wherein the side surface of the cylindrical container has an permeability of less than 1 coresta unit.

16. The tobacco rod according to claim 4 , wherein the side surface of the cylindrical container has an permeability of less than 1 coresta unit.

17. The tobacco rod according to claim 5 , wherein the side surface of the cylindrical container has an permeability of less than 1 coresta unit.

18. 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.

19. 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.

20. The tobacco rod according to claim 1 , wherein the following relationship is satisfied: 5%≤S/T≤17%.
