  • the partition wall 40 has a curved surface 45d on its wall surface 45.
  • the wall surface 45 refers to the surface of the partition wall 40 extending between the two side end portions 43.
  • the partition wall 40 is formed in a curved plate shape as a whole because the two facing wall surfaces 45 have a curved surface 45d.
  • 13A to 13C are cross-sectional views showing a flavor source accommodating body 31 of the cartridge 30 according to another embodiment.
  • 13A to 13C show cross-sectional views at the same positions as in FIG. 7A.
  • the thickness of the partition wall 40 was constant in the entire partition wall 40.
  • the partition wall 40 is formed so that the thickness of the partition wall 40 decreases from the first end portion 41 toward the second end portion 42. Since the thickness of the partition wall 40 is relatively thick at the connection point of the partition wall 40 with the bottom wall 31C, the strength of the connection point between the partition wall 40 and the bottom wall 31C can be improved.
  • the second end portion 42 of the partition wall 40 is thinner than the first end portion 41, the volume of the flavor source accommodating space 37 can be increased as compared with the case where the length of the partition wall 40 is constant.
  • the second end portion 42 of the partition wall 40 is formed in a square shape. Specifically, in the embodiment shown in FIG. 13B, the cross section of the second end portion 42 of the partition wall 40 on the plane parallel to the axial direction of the tubular portion 31B is angular. In the embodiment shown in FIG. 13C, the second end portion 42 of the partition wall 40 is formed in a round shape. Specifically, in the embodiment shown in FIG. 13C, the cross section of the second end portion 42 of the partition wall 40 on the plane parallel to the axial direction of the tubular portion 31B is round.
  • 14A and 14B are cross-sectional views showing a flavor source accommodating body 31 of the cartridge 30 according to another embodiment. 14A and 14B show cross-sectional views at the same positions as FIG. 7B.
  • the second end 42 of the bulkhead 40 extends non-linearly from one of the two side ends 43 towards the other of the two side ends 43.
  • the second end portion 42 of the partition wall 40 is formed in a non-linear manner in the plan view of the partition wall 40 shown in FIGS. 14A and 14B.
  • the second end portion 42 extends from one of the two side end portions 43 toward the other of the two side end portions 43 in a substantially arc shape.
  • FIG. 14A the second end portion 42 extends from one of the two side end portions 43 toward the other of the two side end portions 43 in a substantially arc shape.
  • the second end portion 42 extends substantially angularly from one of the two side end portions 43 toward the other of the two side end portions 43.
  • non-linear means that the linear shape is not linear, and as in the example shown in FIG. 14B, there are a plurality of spaces between one side end portion 43 and the other side end portion 43 (in FIG. 14B).
  • the case of connecting with two) straight lines is also called “non-straight line”.
  • FIG. 15 is a cross-sectional view showing a flavor source accommodating body 31 of the cartridge 30 according to another embodiment.
  • the cartridge 30 has two bulkheads 40.
  • the flavor source 31A is supported by the respective partition walls 40, and it is possible to further suppress the flavor source 31A from being biased downward in the vertical direction.
  • the cartridge 30 preferably has one or more and three or less partition walls 40. When the number of partition walls 40 exceeds 4, the effect of suppressing the flavor source 31A from being biased downward in the vertical direction is not significantly improved, while the flavor source accommodating space 37 becomes smaller and the cartridge 30 has a sufficient amount of flavor source 31A. May not be able to be accommodated.
  • FIG. 16A is a cross-sectional view showing a flavor source accommodating body 31 of the cartridge 30 according to another embodiment.
  • FIG. 16B is a cross-sectional view (16B-16B cross-sectional view shown in FIG. 16A) showing the cartridge 30 according to the present embodiment.
  • the partition wall 40 has four side end portions 43. The four side end portions 43 are in contact with the tubular portion 31B at different positions in the circumferential direction. Specifically, the four side end portions 43 are in contact with the tubular portion 31B in different circumferential directions by 90 °.
  • the partition wall 40 has a cross-shaped second end portion 42 when viewed from the axial direction.
  • the partition wall 40 can support the flavor source 31A even if the cartridge 30 is tilted in any direction when the cartridge 30 is oriented from the vertical direction to the horizontal direction. It is possible to further suppress the flavor source 31A from being biased downward in the vertical direction.
  • Flavor aspirator 30 Cartridge 31: Flavor source accommodating body 31A: Flavor source 31B: Cylindrical portion 31C: Bottom wall 37: Flavor source accommodating space 40: Partition wall 41: First end portion 42: Second end portion 43: Side end 45: Wall surface 45b: Groove 45c: Opening 45d: Curved surface 46: Central CL: Central axis
