Definitions
- the present invention relates to a flavor generating article and a smoking system.
- flavor inhalers for inhaling flavors and the like without burning the material are known.
- smoking material heating devices are known as such flavor inhalers, which form an aerosol by heating smoking material made of tobacco containing volatile components.
- consumables that have a slab of tobacco, a spacer, and a filter are known (see Patent Document 1).
- the object of the present invention is to provide a flavor generating product with a new structure.
- a flavor generating article has a first flavor source sheet, one or more second flavor source sheets that are not in contact with a heat source, a first spacer that contacts the first flavor source sheet and one of the second flavor source sheets and is provided between them, and a first air flow path that is provided between the first flavor source sheet and one of the second flavor source sheets.
- the first spacer provides a first air flow path between the first flavor source sheet and the second flavor source sheet, and therefore the amount of air passing through the first flavor source sheet and the second flavor source sheet can be increased.
- the steam or aerosol generated in the flavor generating article can be efficiently delivered to the user, and the amount of steam or aerosol supplied can be improved.
- the second flavor source sheet since the second flavor source sheet is not in direct contact with the heat source, the second flavor source sheet can be heated by the heat of the heated first flavor source sheet being conducted to the second flavor source sheet via the first spacer. This allows the flavor source to be heated sequentially, starting from the first flavor source sheet closest to the heat source, and therefore allows a stable supply of steam or aerosol to the user during one session from the start of smoking the flavor generating article to the end of smoking.
- the first spacer may include at least one of the group consisting of carbonate, ceramic, carbon, and metal.
- the first spacer can have a considerable strength, it is possible to prevent the first spacer from collapsing and closing the first air flow path.
- the first spacer can have a considerable thermal conductivity, it is possible to efficiently conduct heat from the first flavor source sheet to the second flavor source sheet.
- the first spacer may include calcium carbonate.
- the first spacer can have sufficient strength, so that the first spacer can be prevented from collapsing and closing the first air flow path.
- the first spacer can have good thermal conductivity, so that heat from the first flavor source sheet can be efficiently conducted to the second flavor source sheet.
- the thermal conductivity of the first spacer may be 0.1 w/(m ⁇ k) or more, preferably 1 w/(m ⁇ k) or more, more preferably 2 w/(m ⁇ k) or more, and 300 w/(m ⁇ k) or less, preferably 100 w/(m ⁇ k) or less, more preferably 30 w/(m ⁇ k) or less.
- the heat of the first flavor source sheet can be conducted to the second flavor source sheet at an appropriate speed. If the thermal conductivity of the first spacer is less than 0.1 w/(m ⁇ k), the conduction of heat from the first flavor source sheet to the second flavor source sheet will be slow, and there is a risk that the second flavor source sheet will generate steam or aerosol after the steam or aerosol has finished evaporating from the first flavor source sheet. In other words, there is a risk that there will be a time period during which the amount of steam or aerosol generated is low.
- the thermal conductivity of the first spacer is more than 300 w/(m ⁇ k)
- the conduction of heat from the first flavor source sheet to the second flavor source sheet will be fast, and the time it takes for steam or aerosol to be generated from both the first flavor source sheet and the second flavor source sheet will be longer, and there is a risk that the time of one session from the start of smoking to the end of smoking of the flavor generating article will be shorter.
- the flavor generating article may have a plurality of the second flavor source sheets, a third spacer that is in contact with and between the pair of the second flavor source sheets, and a second air flow path that is between the pair of the second flavor source sheets.
- the third spacer provides a second air flow path between the second flavor source sheets, so that the amount of air passing in contact with each of the second flavor source sheets can be increased.
- This allows the vapor or aerosol generated in the flavor generating article to be delivered efficiently to the user, and the amount of vapor or aerosol supplied can be increased.
- heat can be conducted from one second flavor source sheet to the other second flavor source sheet via the third spacer. Therefore, the second flavor source sheets are heated in sequence starting from the second flavor source sheet closest to the heat source, so that a stable supply of vapor or aerosol can be supplied to the user during one session from the start of smoking the flavor generating article to the end of smoking.
- the thickness of the first flavor source sheet or the second flavor source sheet may be 0.1 mm or more and 1.0 mm or less, preferably 0.6 mm or less, and more preferably 0.3 mm or less.
- steam or aerosol can be appropriately generated while preventing the first or second flavor source sheet from burning.
- the thickness of the first or second flavor source sheet is less than 0.1 mm, the first or second flavor source sheet is too thin, the strength of the first or second flavor source sheet is insufficient, and there is a risk of deterioration in formability and tearing.
- the aerosol source held by the first or second flavor source sheet may be depleted, causing the first or second flavor source sheet to burn.
- the thickness of the first or second flavor source sheet is more than 1.0 mm, the first or second flavor source sheet is too thick, making it difficult for heat to be conducted through the first or second flavor source sheet, and there is a risk that steam or aerosol cannot be appropriately generated from the first or second flavor source sheet.
- the first flavor source sheet may be configured to be in direct or indirect contact with the heat source.
- the heat source can efficiently heat the first flavor source sheet, and as a result, the second flavor source sheet can be heated through the first spacer.
- the flavor-generating article may have a second spacer that is in contact with and disposed between the first flavor source sheet and the heat source.
- the heat source and the first flavor source sheet are in indirect contact via the second spacer, so the heat from the heat source can be conducted to the first flavor source sheet via the second spacer. Also, because the heat source is not in direct contact with the first flavor source sheet, it is possible to prevent the components of the heated first flavor source sheet from adhering to the heat source and contaminating the heat source.
- the thickness of the first spacer may be 0.1 mm or more, preferably 0.2 mm or more, and 0.5 mm or less, preferably 0.3 mm or less.
- the length of the gap between the first flavor source sheet and the second flavor source sheet i.e., the width of the first air flow path
- the first spacer can ensure the amount of air passing through the first air flow path while appropriately conducting heat. If the thickness of the first spacer is less than 0.1 mm, the width of the first air flow path becomes too small, and the amount of air passing in contact with the heated first flavor source sheet and second flavor source sheet may be reduced.
- the thickness of the first spacer is less than 0.1 mm, the speed at which the first spacer conducts heat becomes faster, and the time it takes for vapor or aerosol to be generated from both the first flavor source sheet and the second flavor source sheet becomes longer, and the time of one session from the start of smoking to the end of smoking of the flavor generating article may be shortened.
- the thickness of the first spacer is more than 0.5 mm, the speed at which the first spacer conducts heat becomes slower, and there is a risk that vapor or aerosol will be generated from the second flavor source sheet after the vapor or aerosol has finished evaporating from the first flavor source sheet. That is, there may be times when the amount of vapor or aerosol generated is low.
- the contact area between the first spacer and the second flavor source sheet may be 10% or more, preferably 20% or more, and 70% or less, preferably 50% or less, of the area of the surface of the second flavor source sheet facing the first flavor source sheet.
- the heat of the first flavor source sheet can be conducted to the second flavor source sheet at an appropriate speed while ensuring the flow area of the first air flow path. If the contact area is less than 10%, the heat conduction from the first flavor source sheet to the second flavor source sheet will be slow, and there is a risk that the second flavor source sheet will generate steam or aerosol after the steam or aerosol has finished evaporating from the first flavor source sheet. In other words, there is a risk that there will be a time period during which the amount of steam or aerosol generated is low.
- the contact area is more than 70%, the heat conduction from the first flavor source sheet to the second flavor source sheet will be too fast, and the time it takes for steam or aerosol to be generated from both the first flavor source sheet and the second flavor source sheet will be longer, and the time of one session from the start of smoking to the end of smoking of the flavor generating article will be shorter.
- the contact area is more than 70%, there is a risk that the first spacer will narrow the flow area of the first air flow path too much.
- the ratio of the thickness of the first flavor source sheet to the thickness of the first spacer may be 0.2 or more and 10 or less.
- steam or aerosol can be appropriately generated while preventing the first flavor source sheet from burning.
- heat from the first flavor source sheet can be conducted to the second flavor source sheet at an appropriate speed. If the above ratio is less than 0.2, the thickness of the first flavor source sheet is too thin, and the aerosol source held by the first flavor source sheet may be depleted, causing the first flavor source sheet to burn. Alternatively, if the above ratio is less than 0.2, the first spacer is too thick, slowing down the rate at which the first spacer conducts heat, and steam or aerosol may be generated from the second flavor source sheet after the steam or aerosol has finished evaporating from the first flavor source sheet. In other words, there may be a time period during which the amount of steam or aerosol generated is small.
- the thickness of the first flavor source sheet is too thick, making it difficult for heat to be conducted through the first flavor source sheet, and steam or aerosol may not be appropriately generated from the first flavor source sheet.
- the first spacer may be too thin, the width of the first air flow path may be too small, and the amount of air passing in contact with the heated first flavor source sheet and second flavor source sheet may be reduced.
- the first spacer may conduct heat faster, and the time it takes for vapor or aerosol to be generated from both the first flavor source sheet and the second flavor source sheet may be longer, which may shorten the time of one session from the start to the end of smoking the flavor-generating article.
- the ratio of the thermal conductivity of the first spacer to the thermal conductivity of the first flavor source sheet may be 1.5 or more, preferably 5 or more, more preferably 10 or more, and may be 1500 or less, preferably 1000 or less, more preferably 500 or less, and even more preferably 200 or less.
- heat from the first flavor source sheet can be conducted to the second flavor source sheet at an appropriate speed. If the ratio is less than 1.5, the conduction of heat from the first flavor source sheet to the second flavor source sheet will be slow, and there is a risk that vapor or aerosol will be generated from the second flavor source sheet after the vapor or aerosol has finished evaporating from the first flavor source sheet. In other words, there is a risk that there will be a time period during which the amount of vapor or aerosol generated is low.
- the ratio is more than 1500, the conduction of heat from the first flavor source sheet to the second flavor source sheet will be fast, and the time during which vapor or aerosol is generated from both the first flavor source sheet and the second flavor source sheet will be longer, and there is a risk that the time of one session from the start of smoking to the end of smoking with the flavor generating article will be shorter.
- the first flavor source sheet and the second flavor source sheet may differ from each other in at least one of flavor, thickness, aerosol source content, and surface shape.
- the flavors are different, different flavors can be generated from the first flavor source sheet and the second flavor source sheet. Therefore, by adjusting the delivery amount of each flavor, the desired flavor can be provided to the user.
- the relatively thin flavor source sheet has a fast temperature rise and can efficiently deliver the initial flavor or aerosol.
- the relatively thick flavor source sheet has a gradual temperature rise and the generation of vapor or aerosol can be sustained until the latter half of smoking.
- the flavor source sheet with a relatively low aerosol source content has a fast temperature rise and can efficiently deliver the initial vapor or aerosol.

- the flavor generating article has the heat source, and the heat source may include an inductively heatable susceptor.
- the first flavor source sheet or the second flavor source sheet can be heated by inductively heating the susceptor of the flavor generating article using an induction coil provided in the flavor inhaler.

- the first flavor source sheet that is closer to the heat source is heated before the second flavor source sheet.
- the first flavor source sheet is heated before the second flavor source sheet, and the heat of the heated first flavor source sheet is conducted to the second flavor source sheet via the first spacer, thereby heating the second flavor source sheet.
- This allows the flavor sources to be heated sequentially, starting from the first flavor source sheet that is closest to the heating source, so that a stable supply of vapor or aerosol can be provided to the user during one session, from the start to the end of smoking the flavor-generating article.

If the thermal conductivity of the first spacer 33 is less than 0.1 w/(m ⁇ k), the conduction of heat from the first flavor source sheet 31 to the second flavor source sheet 32 will be slow, and there is a risk that steam or aerosol will be generated from the second flavor source sheet 32 after the steam or aerosol has finished evaporating from the first flavor source sheet 31.

In other words, there may be a time period in which the amount of steam or aerosol generated is low.
- the ratio exceeds 10
