  12. In the smoking system described in claim 11, The flavor inhaler has an air supply port that is radially adjacent to the nozzle and supplies air to the gap between the mouthpiece and the nozzle, A smoking system in which the guide portion is configured to guide the air supplied from the air supply port toward the opening of the mouthpiece.
  13. In the smoking system described in claim 7 , A smoking system in which the nozzle includes a portion whose outer diameter increases from the opening of the nozzle toward the air outlet of the container.
  14. In the smoking system described in claim 7 , The flavor suction device has an air passage that communicates with the air inlet of the container of the flavor generating article, A smoking system wherein the air passage passes outside the side wall of the container and communicates with the air inlet.

Description

This invention relates to a flavor-generating article and a smoking system. Conventionally, flavor inhalers are known for inhaling flavors and aromas without burning the materials. One such flavor inhaler is a smoking material heating device that forms an aerosol by heating a smoking material consisting of tobacco containing volatile components (see Patent Document 1). In the aerosol generation system described in Patent Document 1, an aerosol-forming substrate and a susceptor are housed in a capsule, and the susceptor is induction-heated by induction coils arranged around the sides of the capsule. International Publication No. 2017/068095 This is a schematic side cross-sectional view of the flavor-generating article according to this embodiment.This is a schematic side cross-sectional view of the smoking system in this embodiment.This is a schematic side cross-sectional view of a flavor-generating article according to another embodiment.This is a schematic side cross-sectional view of a flavor-generating article according to another embodiment.This is a schematic side cross-sectional view of a flavor-generating article according to another embodiment.This is a schematic exploded perspective view of a spiral-shaped channel body, which is another example of a curved channel section.This is a schematic exploded perspective view of another example of the spiral flow channel 32.This is a schematic exploded perspective view of a spiral channel body, which is another example of a curved channel section.This is a schematic side cross-sectional view of a flavor-generating article according to another embodiment.This is a plan view showing another example of a check valve used in flavor-generating articles.This is a schematic side cross-sectional view of a flavor-generating article according to another embodiment.This is a schematic side cross-sectional view of a flavor-generating article according to another embodiment.This is a schematic side cross-sectional view of a flavor-generating article according to another embodiment. Embodiments of the present invention will be described below with reference to the drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals, and redundant descriptions are omitted. In this specification, "longitudinal direction" refers to the direction in which air passes through the flavor source of the flavor generating article or the longitudinal axis direction of the flavor generating article. In this specification, "short direction" or "width direction" refers to the direction perpendicular to the longitudinal direction. Figure 1 is a schematic side cross-sectional view of a flavor generating article according to this embodiment. Figure 2 is a schematic side cross-sectional view of a smoking system according to this embodiment. As shown in Figure 2, the smoking system 200 includes a flavor generating article 10 and a flavor inhaler 100. The flavor inhaler 100 is configured to generate flavor-containing vapor or aerosol by heating a flavor source 20 contained in a container 12. The flavor inhaler 100 has a heating source 110 for heating the flavor generating article 10. In the example shown in Figure 2, the flavor inhaler 100 has an induction coil as the heating source 110. However, the flavor inhaler 100 may also have a heating element that can be inserted into the flavor generating article 10, or a heating element that heats the flavor generating article 10 from the outside, as the heating source 110. The heating source 110 is configured to heat the flavor generating article 10 to, for example, 200°C or more and 350°C or less. After use, the flavor-generating item 10 can be removed from the flavor suction device 100 and discarded. A new flavor-generating item 10 can then be used in the flavor suction device 100. In other words, the flavor-generating item 10 is a cartridge used in the flavor suction device 100. As shown in Figure 2, the flavor inhaler 100 has a chamber 120 for housing the flavor generating article 10 and a mouthpiece 130. Furthermore, the flavor inhaler 100 may have a housing 101, a battery 102, and a control unit 103. The housing 101 houses the battery 102, the control unit 103, and the heating source 110. The housing 101 may be divisible into two or more parts. The battery 102 is configured to supply power to the heating source 110 and the control unit 103, etc. For example, the battery 102 is a rechargeable battery or a non-rechargeable battery, such as a lithium-ion battery. The battery 102 may be rechargeable by an external power source. The battery 102 is electrically connected to the heating source 110 via the control unit 103. This allows the battery 102 to supply power to the heating source 110 so as to properly heat the flavor source 20 contained in the flavor generating article 10. The control unit 103 is composed of a CPU and memory, and controls the operation of the flavor inhaler 100. Specifi
