Description

誘導加熱型香味吸引器用の香味源及びその製造方法、誘導加熱型香味吸引器、並びに誘導加熱型香味吸引システムFlavor Source for Induction Heating Flavor Inhaler and Manufacturing Method Thereof, Induction Heating Flavor Inhaler, and Induction Heating Flavor Inhaler System
 本発明は、誘導加熱型香味吸引器用の香味源及びその製造方法、誘導加熱型香味吸引器、並びに誘導加熱型香味吸引システムに関する。 The present invention relates to a flavor source for an induction heating flavor inhaler, a manufacturing method thereof, an induction heating flavor inhaler, and an induction heating flavor inhaling system.
 燃焼型香味吸引器(シガレット)では、葉たばこを含むたばこ充填物を燃焼して香味を得る。該燃焼型香味吸引器の代替として、たばこ材料を含む香味源を燃焼する代わりに加熱して香味を得る非燃焼加熱型香味吸引器が提案されている。非燃焼加熱型香味吸引器の加熱温度は、燃焼型香味吸引器の燃焼温度より低く、例えば約400℃以下である。このように、非燃焼加熱型香味吸引器の加熱温度は低いため、煙量を増加させる観点から、非燃焼加熱型香味吸引器では香味源にグリセリン等のエアロゾル発生剤が添加される。エアロゾル発生剤は加熱により気化し、エアロゾルを発生する。該エアロゾルはたばこ成分等の香味成分を伴い使用者に供給されるため、使用者は十分な香味を得ることができる。 A combustion-type flavor inhaler (cigarette) obtains flavor by burning a tobacco filling containing leaf tobacco. As an alternative to the combustion type flavor inhaler, a non-combustion heating type flavor inhaler has been proposed in which flavor is obtained by heating a flavor source including tobacco material instead of burning it. The heating temperature of the non-combustion-heating flavor inhaler is lower than the combustion temperature of the combustion-type flavor inhaler, for example, about 400° C. or less. Thus, since the heating temperature of the non-combustion heating type flavor inhaler is low, an aerosol generating agent such as glycerin is added to the flavor source in the non-combustion heating type flavor inhaler from the viewpoint of increasing the amount of smoke. The aerosol-generating agent is vaporized by heating to generate an aerosol. Since the aerosol is supplied to the user together with flavor components such as tobacco components, the user can obtain sufficient flavor.
 非燃焼加熱型香味吸引器の一例として誘導加熱型香味吸引器が知られている。誘導加熱型香味吸引器では、誘導加熱により香味源を加熱して香味を得る。例えば電磁誘導の原理を利用して香味源に含まれるサセプタ材料に電流を流し、その電気抵抗によりサセプタ材料を発熱させることで、香味源を加熱することができる。例えば特許文献1及び2には、エアロゾル発生剤及びサセプタ材料を含む香味源が開示されている。 An induction heating flavor inhaler is known as an example of a non-combustion heating flavor inhaler. In the induction heating flavor inhaler, flavor is obtained by heating the flavor source by induction heating. For example, the flavor source can be heated by applying an electric current to the susceptor material contained in the flavor source using the principle of electromagnetic induction and causing the susceptor material to generate heat due to its electrical resistance. For example, US Pat.

 サセプタ材料を含む香味源を備える誘導加熱型香味吸引器では、電磁誘導によりサセプタ材料が発熱し、香味源の温度が、エアロゾル発生剤がエアロゾル化する温度に到達した時点で、エアロゾル発生剤のエアロゾル化が生じる。生成したエアロゾルは、たばこ材料に含まれるたばこ成分等の香味成分を伴って使用者に供給される。その後、香味源中のエアロゾル発生剤が消費されると、生成するエアロゾル量が減少し、使用者に供給されるたばこ成分等の香味成分量も減少する。このように、前記誘導加熱型香味吸引器では、加熱開始後時間の経過と共に使用者に供給される香味成分量は増加し、その後減少するため、使用の開始から終了まで使用者に香味成分が安定的に供給されることが望まれている。 In an induction heating flavor inhaler provided with a flavor source containing a susceptor material, the susceptor material generates heat due to electromagnetic induction, and when the temperature of the flavor source reaches a temperature at which the aerosol generating agent is aerosolized, the aerosol of the aerosol generating agent is generated. change occurs. The generated aerosol is supplied to the user together with flavor components such as tobacco components contained in the tobacco material. Thereafter, when the aerosol-generating agent in the flavor source is consumed, the amount of aerosol generated decreases, and the amount of flavor components such as tobacco components supplied to the user also decreases. As described above, in the induction heating type flavor inhaler, the amount of flavor components supplied to the user increases with the lapse of time after the start of heating, and then decreases, so that the user is supplied with the flavor components from the start to the end of use. A stable supply is desired.
 本発明は、使用の前半から後半まで使用者に香味成分を安定的に供給できる誘導加熱型香味吸引器用の香味源及びその製造方法、誘導加熱型香味吸引器、並びに誘導加熱型香味吸引システムを提供することを目的とする。 The present invention provides a flavor source for an induction heating flavor inhaler that can stably supply flavor components to the user from the first half to the last half of use, a manufacturing method thereof, an induction heating flavor inhaler, and an induction heating flavor inhaling system. intended to provide

[Flavor source for induction heating flavor sucker]
The flavor source for the induction heating flavor inhaler according to the present embodiment (hereinafter also referred to as flavor source) is a flavor source solid containing an aerosol generating agent, a tobacco material solid, a susceptor material solid, and a binder. Including multiple things. That is, one flavor source solid includes an aerosol generating agent, tobacco material solids, susceptor material solids, and a binder, and the flavor source is composed of a plurality of said flavor source solids. The solid flavor source may further contain water. Here, the tobacco material solids and the susceptor material solids are substantially uniformly dispersed in the flavor source solids. That is, inside each of the flavor source solids constituting the flavor source, a plurality of the tobacco material solids and a plurality of the susceptor material solids are arranged in a substantially uniformly dispersed state. Also, the flavor source is composed of two or more types of flavor source solids that differ from each other in the type of susceptor material that constitutes the susceptor material solid and/or the mixing ratio of the susceptor material solid. That is, the flavor source may be composed of at least two types of the flavor source solid matter, and the difference in the types may be based on the type of susceptor material that constitutes the susceptor material solid matter. The difference may be based on the mixing ratio of the material solids, or the difference may be based on the type of the susceptor material constituting the susceptor material solids and the mixing ratio.
 本実施形態に係る香味源は、サセプタ材料固形物を構成するサセプタ材料の種類、及び/又は、サセプタ材料固形物の配合割合が互いに異なる2種類以上の香味源固形物で構成されるが、異なる種類の香味源固形物は、単位質量当たりの熱容量が異なる。そのため、異なる種類の香味源固形物は、異なる加熱プロファイル(横軸:時間、縦軸:香味源固形物温度としたときの温度変遷)を示し、その結果、香味発生プロファイル(横軸:時間、縦軸:香味発生量としたときの香味発生量変遷)も異なる。 The flavor source according to the present embodiment is composed of two or more types of flavor source solids that differ in the type of susceptor material that constitutes the solid susceptor material and/or the mixing ratio of the solid susceptor material. Types of flavor source solids differ in heat capacity per unit mass. Therefore, different types of flavor source solids show different heating profiles (horizontal axis: time, vertical axis: temperature change when the temperature of the flavor source solids is taken as temperature), resulting in a flavor generation profile (horizontal axis: time, Vertical axis: change in the amount of flavor generation when the amount of flavor generation is defined as the amount of flavor generation) is also different.
 例えば、サセプタ材料固形物の配合割合が高い香味源固形物Aは、サセプタ材料固形物以外の材料の熱容量が小さく、またサセプタ材料固形物による発熱量が大きい。そのため、加熱開始後すぐに香味源固形物Aの温度は上昇し、香味源固形物A中のエアロゾル発生剤がエアロゾル化し、香味が発生する。すなわち、図1に示されるように、香味源固形物Aは主に使用前半における香味付与に貢献する。しかし、香味源固形物Aは、使用後半に進むにつれてエアロゾル発生剤が消費されるため、香味供給量が少なくなる。一方、サセプタ材料固形物の配合割合が低い香味源固形物Cは、加熱開始後一定時間が経過してからエアロゾル化が可能な温度に到達し、香味が発生する。そのため、図1に示されるように、香味源固形物Cは主に使用後半における香味付与に貢献する。サセプタ材料固形物の配合割合が香味源固形物AとCの中間である香味源固形物Bは、図1に示されるように、香味源固形物AとCの中間の香味発生プロファイルを示す。このように、異なる香味発生プロファイルを示す複数種類の香味源固形物を組み合わせて使用することにより、図1に示されるように、使用の前半から後半にわたって香味の総量を安定化させることができる。 For example, in the flavor source solid matter A, which has a high mixing ratio of the susceptor material solid matter, the heat capacity of the materials other than the susceptor material solid matter is small, and the susceptor material solid matter generates a large amount of heat. Therefore, the temperature of the solid flavor source A rises immediately after the start of heating, and the aerosol-generating agent in the solid flavor source A is aerosolized to generate flavor. That is, as shown in FIG. 1, the flavor source solid matter A mainly contributes to imparting flavor in the first half of use. However, since the aerosol generating agent is consumed in the latter half of use of the solid flavor source material A, the amount of flavor supply decreases. On the other hand, the flavor source solid material C, which has a low blending ratio of the susceptor material solid material, reaches a temperature at which aerosolization is possible after a certain period of time has passed after the start of heating, and flavor is generated. Therefore, as shown in FIG. 1, the flavor source solid matter C mainly contributes to imparting flavor in the latter half of use. Flavor source solid B, in which the blending ratio of the susceptor material solid is intermediate between flavor source solids A and C, exhibits a flavor development profile intermediate between flavor source solids A and C, as shown in FIG. In this way, by using a combination of multiple types of flavor source solids exhibiting different flavor generation profiles, as shown in FIG. 1, the total amount of flavor can be stabilized from the first half to the second half of use.
 これは、香味源が、サセプタ材料固形物を構成するサセプタ材料の種類が互いに異なる2種類以上の香味源固形物で構成される場合も同様である。例えば、サセプタ材料として比熱容量が小さい材料を用いた場合、該サセプタ材料で構成されるサセプタ材料固形物を含む香味源固形物は、加熱開始後すぐに温度上昇するため、使用前半における香味付与に貢献する。一方、サセプタ材料として比熱容量が大きい材料を用いた場合、該サセプタ材料で構成されるサセプタ材料固形物を含む香味源固形物は、加熱開始後一定時間が経過してからエアロゾル化が可能な温度に到達するため、使用後半における香味付与に貢献する。 This is also the case when the flavor source is composed of two or more types of flavor source solids that are different from each other in the type of susceptor material that constitutes the solid susceptor material. For example, when a material having a small specific heat capacity is used as the susceptor material, the temperature of the flavor source solid containing the susceptor material solid composed of the susceptor material rises immediately after the start of heating. To contribute. On the other hand, when a material having a large specific heat capacity is used as the susceptor material, the flavor source solid matter including the susceptor material solid matter composed of the susceptor material reaches a temperature at which aerosolization is possible after a certain period of time has passed after the start of heating. It contributes to flavoring in the latter half of use.
 さらに、本実施形態に係る香味源では、香味源固形物内において、たばこ材料固形物及びサセプタ材料固形物が略均一に分散しているため、サセプタ材料固形物からたばこ材料固形物へ伝熱する伝熱面積が増加しており、また伝熱面が安定する。これにより、ムラなく均一にたばこ材料固形物及びエアロゾル発生剤が加熱されるため、使用経時における香味の発生量が安定化する。 Furthermore, in the flavor source according to the present embodiment, since the tobacco material solids and the susceptor material solids are substantially uniformly dispersed in the flavor source solids, heat is transferred from the susceptor material solids to the tobacco material solids. The heat transfer area is increased and the heat transfer surface is stabilized. As a result, the solid tobacco material and the aerosol-generating agent are evenly and uniformly heated, so that the amount of generated flavor is stabilized over time.

The tobacco material is not particularly limited as long as it contains tobacco components, but for example, pulverized tobacco raw materials such as lamina (leaf tobacco), pulverized regenerated tobacco (tobacco sheets), and tobacco extracts other than tobacco.

Tobacco material solids can be obtained by compacting tobacco materials by, for example, extrusion molding, and then crushing and sizing them into solids. A solid tobacco material may be used as it is without molding.

(Composition of flavor source)
The flavor source according to this embodiment includes a plurality of the flavor source solids. Here, the flavor source according to the present embodiment is composed of two or more types of flavor source solids that differ from each other in the type of susceptor material that constitutes the solid susceptor material and/or the mixing ratio of the solid susceptor material. .

 例えばサセプタ材料の種類が異なる2種類の香味源固形物を用いる場合、サセプタ材料の組み合わせとしては、アルミニウム/黒鉛等が挙げられる。また、サセプタ材料の種類が異なる3種類の香味源固形物を用いる場合、サセプタ材料の組み合わせとしては、アルミニウム/黒鉛/鉄等が挙げられる。 For example, when using two types of flavor source solids with different types of susceptor materials, a combination of susceptor materials may include aluminum/graphite. Further, when three types of flavor source solids with different types of susceptor materials are used, aluminum/graphite/iron or the like can be used as a combination of susceptor materials.

 なお、本実施形態に係る香味源では、サセプタ材料の種類とサセプタ材料固形物の配合割合が両方共異なる2種類以上の香味源固形物を用いてもよい。この場合、前述したサセプタ材料の組み合わせと配合割合の組み合わせの両方共を適用することができる。 In addition, in the flavor source according to the present embodiment, two or more types of flavor source solids having different types of susceptor materials and different mixing ratios of the susceptor material solids may be used.

It is preferably composed of solid matter. When a magnetic substance is used as the solid susceptor material, the maximum temperature of the solid susceptor material during induction heating is determined by the Curie temperature of the susceptor material. are equal, the temperature control of the flavor source solid is facilitated. In addition, it is possible to prevent the temperature of the solid flavor source from which the flavor component has been released first from becoming higher than necessary. On the other hand, since the mixing ratio of the susceptor material solids is different from each other, each flavor source solid can exhibit a different flavor generation profile, and the total amount of flavor can be stabilized from the first half to the second half of use. In the present embodiment, when different types of susceptor materials are used to form the solid susceptor material, it is preferable to use susceptor materials having similar Curie temperatures from the above-described viewpoint. is preferably

For example, when the flavor source consists of two different types of flavor source solids A and B, the flavor source may contain 40 to 60% by mass of the flavor source solids A and 40 to 60% by mass of the flavor source solids B. More preferably, it contains 50% by mass of the solid flavor source A and 50% by mass of the solid flavor source B. Further, for example, when the flavor source consists of three different types of flavor source solids A, B, and C, the flavor source is 30 to 40% by mass of the solid flavor source A and 30 to 40% by mass of the solid flavor source B. %, preferably contains 30 to 40% by mass of the flavor source solid C, 33.3% by mass of the flavor source solid A, 33.3% by mass of the flavor source solid B, and 33.3% by mass of the flavor source solid C. It is more preferable to contain 3% by mass.
 香味源の形態は特に限定されないが、例えば粒子であってもよく、複数の香味源固形物が少し押し固められ、まとめられたような形態であってもよい。 Although the form of the flavor source is not particularly limited, it may be, for example, a particle, or a form in which a plurality of flavor source solids are slightly pressed and consolidated.

The container 3 can be columnar such as a cylinder, and has a flow path 4 that allows flow from the end surface (bottom surface) of the container 3 on the non-mouthpiece end 5 side to the end surface (top surface) on the mouthpiece end 6 side. As shown in FIG. 2(b), a cap 7 is provided at the end of the container 3 on the mouthpiece end 6 side, and the cap 7 has a mouthpiece.

 香味源が、サセプタ材料固形物を構成するサセプタ材料の種類が互いに同一であり、かつ、サセプタ材料固形物の配合割合が互いに異なる2種類以上又は3種類以上の香味源固形物で構成される場合、収容体内において、吸口端側から非吸口端側へ向けてサセプタ材料固形物の配合割合が低くなるように、2種類以上又は3種類以上の香味源固形物が配置されていることが好ましい。例えばサセプタ材料固形物の配合割合が香味源固形物A>香味源固形物B>香味源固形物Cである3種類の香味源固形物A~Cを香味源として用いる場合、収容体内において香味源固形物は図3(a)に示されるように、吸口端側から非吸口端側へ向けて、香味源固形物A、香味源固形物B、香味源固形物Cの順序で配置されていることが好ましい。 When the flavor source is composed of two or more or three or more flavor source solids in which the types of susceptor materials constituting the susceptor material solids are the same and the mixing ratio of the susceptor material solids is different from each other. Preferably, two or more or three or more types of flavor source solids are arranged in the container so that the mixing ratio of the susceptor material solids decreases from the mouth end side toward the non-mouth end side. For example, when three types of flavor source solids A to C are used as flavor sources, the mixing ratio of the susceptor material solids is flavor source solid A>flavor source solid B>flavor source solid C. As shown in FIG. 3(a), the solids are arranged in the order of flavor source solids A, flavor source solids B, and flavor source solids C from the mouth end side toward the non-mouth end side. is preferred.
 使用の開始から終了まで使用者に香味成分を安定的に供給するに際し、特に使用初期は加熱に時間がかかるため、使用初期の香味量の増加は課題の一つとして挙げられる。ここで、温度上昇の遅いサセプタ材料固形物の配合割合が低い香味源固形物(香味源固形物C)が吸口端側に配置されていると、使用初期において温度が十分に上昇していない前記香味源固形物部分においてエアロゾルが凝縮され、捕捉されやすくなる。そこで、吸口端側から非吸口端側へ向けてサセプタ材料固形物の配合割合が低くなるように香味源固形物を配置することで、使用初期におけるエアロゾルの凝縮、捕捉が抑制され、1パフ目からすぐに香味成分が使用者に供給される。その結果、使用初期の香味量が増加し、使用の開始から終了まで使用者に香味成分をより安定的に供給できる。 When supplying flavor components to users stably from the start to the end of use, it takes time to heat, especially at the beginning of use, so increasing the amount of flavor at the beginning of use is one of the challenges. Here, if the flavor source solid matter (flavor source solid matter C) with a low mixing ratio of the susceptor material solid matter whose temperature rises slowly is arranged on the mouthpiece end side, the temperature does not rise sufficiently at the initial stage of use. The aerosol is condensed in the flavor source solid portion and becomes more likely to be trapped. Therefore, by arranging the flavor source solids so that the blending ratio of the susceptor material solids decreases from the mouth end side to the non-mouth end side, the condensation and trapping of the aerosol at the initial stage of use are suppressed, and the first puff The flavoring component is immediately supplied to the user from. As a result, the amount of flavor at the beginning of use is increased, and the flavor component can be more stably supplied to the user from the start to the end of use.
 また、香味源が、サセプタ材料固形物を構成するサセプタ材料の種類が互いに同一であり、かつ、サセプタ材料固形物の配合割合が互いに異なる2種類以上又は3種類以上の香味源固形物で構成される場合、収容体内において収容体の中心軸から外周へ向けてサセプタ材料固形物の配合割合が低くなるように、2種類以上又は3種類以上の香味源固形物が配置されていることが好ましい。例えばサセプタ材料固形物の配合割合が香味源固形物A>香味源固形物B>香味源固形物Cである3種類の香味源固形物A~Cを香味源として用いる場合、収容体内において香味源固形物は図3(b)に示されるように、収容体の中心軸10から外周11へ向けて、香味源固形物A、香味源固形物B、香味源固形物Cの順序で配置されていることが好ましい。 In addition, the flavor source is composed of two or more or three or more flavor source solids in which the types of susceptor materials constituting the susceptor material solids are the same and the blending ratios of the susceptor material solids are different from each other. In this case, it is preferable that two or more or three or more types of flavor source solids are arranged in the container such that the mixing ratio of the susceptor material solids decreases from the central axis of the container toward the outer periphery. For example, when three types of flavor source solids A to C are used as flavor sources, the mixing ratio of the susceptor material solids is flavor source solid A>flavor source solid B>flavor source solid C. As shown in FIG. 3(b), the solids are arranged in the order of flavor source solids A, flavor source solids B, and flavor source solids C from the center axis 10 toward the outer periphery 11 of the container. preferably.
 使用時、収容体の外周壁面に近いほど吸引される空気の流れは遅くなるため、空気の流れが速い中心軸近傍に温度上昇の早い香味源固形物(香味源固形物A)を配置することで、1パフ目からすぐに香味成分が使用者に供給される。その結果、使用初期の香味量が増加し、使用の開始から終了まで使用者に香味成分をより安定的に供給できる。 During use, the closer to the outer wall surface of the container, the slower the flow of sucked air. Therefore, the flavor source solid matter (flavor source solid matter A) whose temperature rises quickly should be placed near the central axis where the air flow is fast. Thus, the flavor component is immediately supplied to the user from the first puff. As a result, the amount of flavor at the beginning of use is increased, and the flavor component can be more stably supplied to the user from the start to the end of use.
