Definitions

• the present invention relates to a flavor generating article.
• Flavor inhalers for inhaling flavors, etc. without burning of materials are conventionally known.
• Smoking material heating devices which heat a smoking material comprising tobacco that contains volatile components to form an aerosol, are known as an example of such flavor inhalers.
• a consumable comprising a tobacco slab, a spacer, and a filter is known as such a smoking material (see PTL 1).
• the essential point of a third aspect which is in accordance with the first or second aspect, lies in the fact that the first sheet comprises a first face facing the susceptor-containing sheet, and a second face opposite the first face, a liner sheet being provided on the second face.
• the essential point of a fifth aspect which is in accordance with the third or fourth aspect, lies in the fact that a gap between the first sheet and the liner sheet is partially or completely closed.
• the essential point of a sixth aspect which is in accordance with any of the first to fifth aspects, lies in the fact that at least one of the first sheet and the second sheet comprises paper or molded pulp.
• the essential point of a seventh aspect which is in accordance with any of the first to sixth aspects, lies in the fact that the height of wave portions of at least one of the first sheet and the second sheet is 0.2 mm to 2.0 mm.
• the height of the wave portions is less than 0.2 mm, then the gaps between the susceptor-containing sheet and at least one of the first sheet and second sheet will be excessively small, so there is a risk that efficient downstream delivery of the flavor or aerosol generated from the tobacco will no longer be possible. Furthermore, in that case, there is also a risk of a reduction in heat insulation afforded by the gaps between the susceptor-containing sheet and at least one of the first sheet and second sheet. If the height of the wave portions is greater than 2.0 mm, then the flavor generating article will be excessively large in size. According to the seventh aspect, the flavor or aerosol can therefore be efficiently delivered and the size of the flavor generating article can be limited.
• the essential point of an eighth aspect which is in accordance with any of the first to seventh aspects, lies in the fact that the height of wave portions of the first sheet and the height of wave portions of the second sheet are different.
• the gap between the susceptor-containing sheet and the first sheet, and the gap between the susceptor-containing sheet and the second sheet can be made different sizes. Accordingly, when a structure is formed by laminating a first tobacco sheet and a second tobacco sheet comprising different tobacco flavours, for example, a first flavor from the first tobacco sheet is made to pass through a first gap and a second flavor from the second tobacco sheet is made to pass through a second gap, whereby the desired flavor can be supplied to the user by adjusting respective delivery amounts thereof.
• the essential point of a ninth aspect which is in accordance with any of the first to eighth aspects, lies in the fact that the width of wave portions of at least one of the first sheet and the second sheet is 0.2 mm to 2.0 mm.
• the width of the wave portions is less than 0.2 mm, then there is a risk of an undesirable increase in suction resistance when the aerosol passes between waves before being inhaled. If this width is greater than 2.0 mm, then there is a risk of a reduction in strength of the flavor generating article. According to the ninth aspect, the strength of the flavor generating article can therefore be maintained while an undesirable increase in suction resistance is suppressed.
• the flavoring material can be supplied to the user in addition to the flavor or aerosol.
• the essential point of an 11th aspect which is in accordance with any of the first to 10th aspects, lies in the fact that the susceptor-containing sheet extends only partly in a longitudinal direction or a width direction of the flavor generating article.
• the susceptor-containing sheet has a smaller length or width than the overall length or width of the flavor generating article. Accordingly, the flavor generating article does not need to be provided with a susceptor-containing sheet having the same size as the overall size of the flavor generating article, so the required amount of susceptor-containing sheet can be provided for the flavor generating article and the amount of susceptor material can be reduced.
• the flavor generating article 10 will be excessively large in size.
• the flavor or aerosol can therefore be efficiently delivered and the size of the flavor generating article 10 can be limited if the height h1 of the wave portions is within the numerical value range above.
• the susceptor-containing sheet 20 may extend only partly in the longitudinal direction d1 or a width direction d2 of the flavor generating article 10.
• the susceptor-containing sheet 20 may have a smaller length or width than the overall length or width of the flavor generating article 10. Accordingly, the flavor generating article 10 does not need to be provided with a susceptor-containing sheet 20 having the same size as the overall size of the flavor generating article 10, so the required amount of susceptor-containing sheet 20 can be provided for the flavor generating article 10 and the amount of susceptor material can be reduced.
• Fig. 6A is a view in cross section showing the configuration of the susceptor-containing sheet 20 in the flavor generating article 10 according to this embodiment.
• Fig. 6B is a view in cross section showing the configuration of the susceptor-containing sheet 20 in a flavor generating article 10 according to another embodiment.
• the susceptor-containing sheet 20 according to this embodiment may comprise a sheet-form susceptor material 25, and a tobacco sheet 21 laminated on the sheet-form susceptor material 25.
• the tobacco sheet 21 can be heated by means of induction heating of the sheet-form susceptor material 25.
• the first tobacco sheet 21a and the second tobacco sheet 21b are tobacco sheets with different types of tobacco blended therein, such as Burley, yellow, Oriental or native type, or with different tobacco blending ratios.
• the temperature of the relatively thin tobacco sheet rises more rapidly, enabling efficient initial delivery of the flavor or aerosol.
• the temperature of the relatively thick tobacco sheet rises more slowly, making it possible to maintain flavor or aerosol generation to the latter stage of smoking.
• the aerosol source contents are different, the temperature of the tobacco sheet having a relatively small aerosol source content rises more rapidly, enabling efficient initial delivery of the flavor or aerosol.
• the temperature of the tobacco sheet having a relatively large aerosol source content rises more slowly, making it possible to maintain flavor or aerosol generation to the latter stage of smoking.
• the tobacco sheet with the relatively large surface area enables efficient initial delivery of the flavor or aerosol.
• the temperature of the tobacco sheet having a relatively small surface area rises more slowly, making it possible to maintain flavor or aerosol generation to the latter stage of smoking.
• the first sheet 42 and the second sheet 44 have the same waveform cross-sectional shape, as described above. This is not limiting, however, and the height of the wave portions of the first sheet 42 and the height of the wave portions of the second sheet 44 may be different. In this case, the gap S1 between the susceptor-containing sheet 20 and the first sheet 42, and the gap S2 between the susceptor-containing sheet 20 and the second sheet 44 can be made different sizes. Accordingly, when the susceptor-containing sheet 20 is formed by laminating the first tobacco sheet 21a and the second tobacco sheet 21b, as shown in fig.
• a first flavor from the first tobacco sheet 21a is made to pass through the gap S1 and a second flavor from the second tobacco sheet 21b is made to pass through the gap S2, whereby the desired flavor can be supplied to the user by adjusting respective delivery amounts thereof.
• the thickness of the tobacco sheet 21 shown in fig. 6A and fig. 6B is preferably 0.25 mm to 4.0 mm. If the thickness of the tobacco sheet 21 is less than 0.25 mm, then there is a risk of a reduction in the amount of flavor or aerosol generated per unit area of the sheet. If the thickness of the tobacco sheet 21 is greater than 4.0 mm, then the flavor generating article 10 will be excessively large in size. In that case, it takes time to heat the tobacco sheet 21, and there is a risk of more time being needed until the first puff, and of the amount delivered by the first puff being inadequate. The flavor or aerosol can therefore be sufficiently generated and the size of the flavor generating article 10 can be limited if the thickness of the tobacco sheet 21 is within the numerical value range above. It should be noted that when the tobacco sheet 21 comprises multiple tobacco sheets, as shown in fig. 6A , the thickness as referred to here means the total thickness of the multiple tobacco sheets.
• a sheet produced from tobacco leaf, a cast sheet of tobacco leaf, or a rolled sheet of tobacco leaf, etc. may be used as the tobacco sheet 21 shown in fig. 6A and fig. 6B .
• the tobacco sheet 21 may further comprise an aerosol source.
• the aerosol source is preferably a polyhydric alcohol, and may be, for example, glycerol, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof.
• the tobacco sheet 21 may also comprise the flavoring materials mentioned above which may be added to the first sheet 42 and the second sheet 44.
• Fig. 7A is a view in cross section showing the configuration of the susceptor-containing sheet 20 in a flavor generating article 10 according to another embodiment.
• Fig. 7B is a view in cross section showing the configuration of the susceptor-containing sheet 20 in a flavor generating article 10 according to yet another embodiment.
• the susceptor-containing sheets 20 shown in fig. 7A and fig. 7B differ from the susceptor-containing sheets 20 shown in fig. 6A and fig. 6B in that the former do not contain tobacco.
• the susceptor-containing sheet 20 shown in fig. 7A consists only of the sheet-form susceptor material 25. Furthermore, the susceptor-containing sheet 20 shown in fig.
• the susceptor-containing sheets 20 shown in fig. 7A and fig. 7B do not contain tobacco, in which case at least one of the first sheet 42 and the second sheet 44 shown in fig. 3-5 therefore contains the tobacco.
• the tobacco contained in at least one of the first sheet 42 and the second sheet 44 can be heated by induction heating of the susceptor-containing sheet 20, and the flavor or aerosol can be produced.
• the non-tobacco sheet 27 in the susceptor-containing sheet 20 shown in fig. 7B may comprise paper or molded pulp. A lightweight, inexpensive and robust flavor generating article 10 can be formed by this means.
• the non-tobacco sheet 27 may be a nonwoven fabric or the like, for example.
• the non-tobacco sheet 27 may hold an aerosol source. The amount of aerosol delivered to the user can be increased in this case.
