　本発明は、非燃焼加熱型香味吸引器及びカートリッジに関する。 The present invention relates to a non-combustion heating flavor inhaler and cartridge.
　電源から供給される電力によって、燃焼を伴わずにエアロゾル源を加熱して霧化し、生成したエアロゾルを、たばこ由来成分を含むたばこ源に通じて該エアロゾルにたばこ由来成分を移行させ、該たばこ由来成分を使用者へ供給する非燃焼加熱型香味吸引器が知られている（例えば特許文献１、２）。該非燃焼加熱型香味吸引器は、例えば、エアロゾル源及び該エアロゾル源を加熱して霧化する霧化手段を含むカートリッジと、該霧化手段に電力を供給する電源ユニットと、該カートリッジの下流に配置された、たばこ源を含む香味付与カートリッジと、を備えることができる。該エアロゾル源は、メンソール等の香料成分を含むこともできる。また、香味付与カートリッジを備えず、代わりにエアロゾル源がたばこ由来成分を含む非燃焼加熱型香味吸引器も知られている。 Electric power supplied from a power source heats and atomizes the aerosol source without combustion, passes the generated aerosol through the tobacco source containing the tobacco-derived component, transfers the tobacco-derived component to the aerosol, and transfers the tobacco-derived component to the aerosol. Non-combustion heated flavor inhalers for supplying ingredients to users are known (eg, Patent Documents 1 and 2). The non-combustion heating type flavor inhaler comprises, for example, a cartridge including an aerosol source and atomization means for heating and atomizing the aerosol source, a power supply unit for supplying power to the atomization means, and downstream of the cartridge. and a flavoring cartridge containing a tobacco source positioned thereon. The aerosol source may also contain perfume ingredients such as menthol. Also known are non-combustion heated flavor inhalers that do not have a flavoring cartridge, but instead the aerosol source contains tobacco-derived components.

　本実施形態に係る非燃焼加熱型香味吸引器では、エアロゾル源を霧化してエアロゾルを生成する際に、前記式（１）で示される化合物がエアロゾルへ移行する。前記式（１）で示される化合物は沸点が高いため、前記式（１）で示される化合物がエアロゾルに含まれると、エアロゾル粒子が蒸発しにくくなり、安定化する。また、前記式（１）で示される化合物は、ニコチン等のたばこ由来成分やメンソール等の香料成分の溶解度が高い。したがって、エアロゾル粒子に前記式（１）で示される化合物が含まれることにより、エアロゾル粒子中に前記たばこ由来成分や前記香料成分をより多く含有でき、また前記たばこ由来成分や前記香料成分がエアロゾル粒子外に放出されにくくなる。これらにより、本実施形態に係る非燃焼加熱型香味吸引器ではエアロゾル経路内における香味成分の損失が抑制されると考えられる。 In the non-combustion heating type flavor inhaler according to this embodiment, when the aerosol source is atomized to generate an aerosol, the compound represented by the formula (1) migrates to the aerosol. Since the compound represented by the formula (1) has a high boiling point, when the compound represented by the formula (1) is contained in the aerosol, the aerosol particles are less likely to evaporate and stabilize. In addition, the compound represented by the formula (1) has a high solubility of tobacco-derived components such as nicotine and flavoring components such as menthol. Therefore, by including the compound represented by the formula (1) in the aerosol particles, the tobacco-derived component and the flavoring component can be contained in a larger amount in the aerosol particles, and the tobacco-derived component and the flavoring component can be included in the aerosol particles. less likely to be released to the outside. It is considered that the non-combustion heating type flavor inhaler according to the present embodiment suppresses the loss of flavor components in the aerosol path.

　本実施形態に係る非燃焼加熱型香味吸引器は、前記エアロゾル源よりも下流側に配置された、たばこ由来成分を含むたばこ源をさらに含むことができる。エアロゾル源の霧化により生成したエアロゾルがたばこ源を通過することで、たばこ源に含まれるたばこ由来成分がエアロゾルへ移行し、使用者へ供給される。たばこ由来成分としては、例えばニコチン等が挙げられる。なお、たばこ源に含まれるたばこ由来成分はエアロゾルによって搬送されるため、使用時にたばこ源自体を加熱する必要はない。また、本実施形態に係る非燃焼加熱型香味吸引器はたばこ源を含まなくてもよく、この場合エアロゾル源がたばこ由来成分を含むことができる。例えば、エアロゾル源中にたばこ源を浸漬させる、たばこ源から抽出した液体のたばこ由来成分をエアロゾル源に混合する、化学合成により得られたたばこ由来成分をエアロゾル源に混合する、等によりエアロゾル源にたばこ由来成分を含ませることができる。 (tobacco source)
The non-combustion-heated flavor inhaler according to this embodiment can further include a tobacco source containing a tobacco-derived component located downstream of the aerosol source. When the aerosol generated by atomization of the aerosol source passes through the tobacco source, tobacco-derived components contained in the tobacco source are transferred to the aerosol and supplied to the user. Examples of tobacco-derived components include nicotine and the like. Since the tobacco-derived component contained in the tobacco source is delivered by the aerosol, it is not necessary to heat the tobacco source itself during use. Also, the non-combustion heating flavor inhaler according to this embodiment may not contain a tobacco source, in which case the aerosol source may contain a tobacco-derived component. For example, the tobacco source is immersed in the aerosol source, the liquid tobacco-derived component extracted from the tobacco source is mixed with the aerosol source, the tobacco-derived component obtained by chemical synthesis is mixed with the aerosol source, and the like. Tobacco-derived ingredients can be included.
　前記たばこ源は、エアロゾル源の霧化により発生するエアロゾルにたばこ由来成分を付与する原料片によって構成されることができる。原料片のサイズは、０．２～１．２ｍｍであることが好ましく、０．２～０．７ｍｍであることがより好ましい。該原料片のサイズが小さいほど比表面積が増大するため、該原料片からたばこ由来成分が放出されやすい。したがって、所望量のたばこ由来成分をエアロゾルに付与するにあたって、原料片の量を低減できる。該原料片としては、刻みたばこ、たばこ原料を粒状に成形した成形体、たばこ原料をシート状に成形した成形体等を用いることができる。 The tobacco source can be composed of raw material pieces that impart tobacco-derived components to the aerosol generated by atomization of the aerosol source. The size of the raw material pieces is preferably 0.2 to 1.2 mm, more preferably 0.2 to 0.7 mm. Since the smaller the size of the raw material pieces, the greater the specific surface area, the tobacco-derived components are more likely to be released from the raw material pieces. Therefore, the amount of raw material pieces can be reduced in applying the desired amount of tobacco-derived component to the aerosol. As the raw material pieces, shredded tobacco, a molded product obtained by molding tobacco raw material into granules, a molded product obtained by molding tobacco raw material into a sheet shape, and the like can be used.
　ここで、前記原料片は、例えば、ＪＩＳ　Ｚ　８８０１に準拠したステンレス篩を用いて、ＪＩＳ　Ｚ　８８１５に準拠する篩分けによって得られる。例えば、０．７１ｍｍの目開きを有するステンレス篩を用いて、乾燥式かつ機械式振とう法によって２０分間に亘って原料片を篩分けによって、０．７１ｍｍの目開きを有するステンレス篩を通過する原料片を得る。続いて、０．２１２ｍｍの目開きを有するステンレス篩を用いて、乾燥式かつ機械式振とう法によって２０分間に亘って原料片を篩分けによって、０．２１２ｍｍの目開きを有するステンレス篩を通過する原料片を取り除く。すなわち、前記原料片は、上限を規定するステンレス篩（目開き＝０．７１ｍｍ）を通過し、下限を規定するステンレス篩（目開き＝０．２１２ｍｍ）を通過しない原料片である。したがって、原料片のサイズの上限は、上限を規定するステンレス篩の目開きによって定義され、前記原料片のサイズの下限は、下限を規定するステンレス篩の目開きによって定義される。 Here, the raw material pieces are obtained by sieving according to JIS Z 8815 using a stainless steel sieve according to JIS Z 8801, for example. For example, using a stainless steel sieve with an opening of 0.71 mm, the raw material pieces are sieved for 20 minutes by a dry and mechanical shaking method to pass through a stainless steel sieve with an opening of 0.71 mm. Obtain raw material pieces. Subsequently, using a stainless sieve with an opening of 0.212 mm, the raw material pieces are sieved for 20 minutes by a dry and mechanical shaking method to pass through a stainless sieve with an opening of 0.212 mm. remove the raw material pieces. That is, the raw material piece is a raw material piece that passes through a stainless sieve (opening=0.71 mm) that defines the upper limit and does not pass through a stainless sieve (opening=0.212 mm) that defines the lower limit. Therefore, the upper limit of the size of the raw material piece is defined by the opening of the stainless sieve that defines the upper limit, and the lower limit of the size of the raw material piece is defined by the opening of the stainless sieve that defines the lower limit.
　前記たばこ源は、たばこ由来成分に加えて、香料成分を含んでもよい。例えば、前記原料片は、たばこ由来成分に加えて、香料成分を含むことができる。香料成分としては、前述した香料成分が挙げられ、メンソールを含むことが好ましい。また、前記原料片が、ミント、ハーブ等のたばこ以外の植物を含むこともできる。 The tobacco source may contain flavor components in addition to tobacco-derived components. For example, the raw material piece may contain a flavor component in addition to the tobacco-derived component. Examples of the perfume component include the perfume components described above, and it is preferable that menthol is included. The raw material pieces may also contain plants other than tobacco, such as mint and herbs.
　前記たばこ源は、後述するように例えばカートリッジの下流に設けられた、香味付与カートリッジ内に配置されることができる。 The tobacco source can be placed in a flavoring cartridge, for example provided downstream of the cartridge as described below.
　（カートリッジ）
　本実施形態に係るカートリッジは、前記式（１）で示される化合物を含むエアロゾル源を含む。該カートリッジは、非燃焼加熱型香味吸引器に着脱可能に取り付けられる。該カートリッジは、後述するように該エアロゾル源を霧化してエアロゾルを生成する霧化手段を備えてもよい。 (cartridge)
The cartridge according to this embodiment includes an aerosol source containing the compound represented by Formula (1) above. The cartridge is detachably attached to a non-combustion heated flavor inhaler. The cartridge may comprise atomization means for atomizing the aerosol source to produce an aerosol, as described below.
　（非燃焼加熱型香味吸引器の構成）
　本実施形態に係る非燃焼加熱型香味吸引器の一例を図１に示す。図１に示される非燃焼加熱型香味吸引器１００は、燃焼を伴わずに香味成分を吸引するための器具であり、非吸口端から吸口端に向かう方向である所定方向Ａに沿って延びる形状を有する。図２は、図１において、香味付与カートリッジ１３０が組み込まれたカートリッジ１１１を示す図である。なお、以下においては、非燃焼加熱型香味吸引器１００を単に香味吸引器１００と称することがある。 (Configuration of non-combustion heating type flavor inhaler)
An example of the non-combustion heating type flavor inhaler according to this embodiment is shown in FIG. The non-combustion-heating flavor inhaler 100 shown in FIG. 1 is a device for inhaling flavor components without combustion, and has a shape extending along a predetermined direction A, which is the direction from the non-suction end to the suction end. have FIG. 2 is a diagram showing the cartridge 111 in which the flavor imparting cartridge 130 is incorporated in FIG. Note that the non-combustion heating type flavor inhaler 100 may be simply referred to as the flavor inhaler 100 hereinafter.
　図１に示されるように、香味吸引器１００は、吸引器本体１１０と、たばこ源を備える香味付与カートリッジ１３０とを有する。吸引器本体１１０は、香味吸引器１００の本体を構成しており、香味付与カートリッジ１３０を接続可能な形状を有する。具体的には、吸引器本体１１０は、吸引器ハウジング１１０Ｘを有しており、香味付与カートリッジ１３０は、吸引器ハウジング１１０Ｘの吸口端に接続される。吸引器本体１１０は、燃焼を伴わずにエアロゾル源を霧化するように構成された、本実施形態に係るエアロゾル源と霧化手段を備えるカートリッジ１１１と、電源ユニット１１２とを有する。 As shown in FIG. 1, the flavor inhaler 100 has an inhaler body 110 and a flavoring cartridge 130 with a tobacco source. The inhaler main body 110 constitutes the main body of the flavor inhaler 100 and has a shape to which the flavor imparting cartridge 130 can be connected. Specifically, the aspirator body 110 has an aspirator housing 110X, and the flavoring cartridge 130 is connected to the mouthpiece end of the aspirator housing 110X. The inhaler body 110 comprises a cartridge 111 comprising an aerosol source and atomization means according to the present embodiment, configured to atomize the aerosol source without combustion, and a power supply unit 112 .
　カートリッジ１１１は、吸引器ハウジング１１０Ｘの一部を構成する第１筒体１１１Ｘを有する。カートリッジ１１１は、図２に示されるように、リザーバ１１１Ｐと、ウィック１１１Ｑと、霧化手段１１１Ｒとを有する。リザーバ１１１Ｐ、ウィック１１１Ｑ及び霧化手段１１１Ｒは、第１筒体１１１Ｘに収容される。第１筒体１１１Ｘは、所定方向Ａに沿って延びる筒状形状（例えば、円筒形状）を有する。リザーバ１１１Ｐは、本実施形態に係るエアロゾル源を保持する。例えば、リザーバ１１１Ｐは、樹脂ウェブ等の材料によって構成される孔質体である。ウィック１１１Ｑは、リザーバ１１１Ｐから供給されるエアロゾル源を保持する液保持部材の一例である。例えば、ウィック１１１Ｑは、ガラス繊維によって構成される。霧化手段１１１Ｒは、ウィック１１１Ｑによって保持されるエアロゾル源を霧化する。霧化手段１１１Ｒは、例えば、ウィック１１１Ｑに所定ピッチで巻き回される発熱抵抗体（例えば、電熱線）によって構成されることができる。 The cartridge 111 has a first cylindrical body 111X that forms part of the aspirator housing 110X. The cartridge 111, as shown in FIG. 2, has a reservoir 111P, a wick 111Q and an atomizing means 111R. The reservoir 111P, the wick 111Q and the atomizing means 111R are accommodated in the first cylindrical body 111X. The first tubular body 111X has a tubular shape (for example, a cylindrical shape) extending along the predetermined direction A. As shown in FIG. Reservoir 111P holds an aerosol source according to this embodiment. For example, the reservoir 111P is a porous body made of a material such as a resin web. The wick 111Q is an example of a liquid retaining member that retains the aerosol source supplied from the reservoir 111P. For example, the wick 111Q is made of glass fiber. The atomizing means 111R atomizes the aerosol source held by the wick 111Q. The atomization means 111R can be composed of, for example, a heating resistor (for example, a heating wire) wound around the wick 111Q at a predetermined pitch.
　霧化手段１１１Ｒによって発生するエアロゾルの流路に露出する壁面には、凝縮したエアロゾルを吸収する吸収部材１１１Ｓが設けられる。エアロゾルの流路に露出する壁面は、例えば、エアロゾルの流路に露出する第１筒体１１１Ｘの内面、エアロゾルの流路に露出するリザーバ１１１Ｐの外面などである。ここで、吸収部材１１１Ｓがリザーバ１１１Ｐと接触していない場合には、吸収部材１１１Ｓによって吸収されたエアロゾル（凝縮したエアロゾル）は、毛細管現象を利用して吸収部材１１１Ｓから霧化手段１１１Ｒに導かれることが好ましい。一方で、吸収部材１１１Ｓがリザーバ１１１Ｐと接触している場合には、吸収部材１１１Ｓによって吸収されたエアロゾル（凝縮したエアロゾル）は、吸収部材１１１Ｓからリザーバ１１１Ｐに導かれることが好ましい。吸収部材１１１Ｓは、凝縮したエアロゾルを吸収する機能を有する部材であればよく、例えば、リザーバ１１１Ｐと同様の材料（樹脂ウェブ）によって構成されていてもよく、ウィック１１１Ｑと同様の材料（ガラス繊維）によって構成されてもよい。 An absorption member 111S that absorbs condensed aerosol is provided on the wall surface exposed to the flow path of the aerosol generated by the atomization means 111R. The wall surfaces exposed to the aerosol flow path are, for example, the inner surface of the first cylindrical body 111X exposed to the aerosol flow path, the outer surface of the reservoir 111P exposed to the aerosol flow path, and the like. Here, when the absorbing member 111S is not in contact with the reservoir 111P, the aerosol (condensed aerosol) absorbed by the absorbing member 111S is led from the absorbing member 111S to the atomizing means 111R using capillary action. is preferred. On the other hand, when the absorbing member 111S is in contact with the reservoir 111P, the aerosol (condensed aerosol) absorbed by the absorbing member 111S is preferably guided from the absorbing member 111S to the reservoir 111P. The absorbing member 111S may be a member having a function of absorbing condensed aerosol, and may be made of the same material (resin web) as the reservoir 111P, or the same material (glass fiber) as the wick 111Q. may be configured by
　電源ユニット１１２は、吸引器ハウジング１１０Ｘの一部を構成する第２筒体１１２Ｘを有する。電源ユニット１１２は、インレット１１２Ａを有する。インレット１１２Ａから流入する空気は、図２に示されるように、カートリッジ１１１（霧化手段１１１Ｒ）に導かれる。詳細には、電源ユニット１１２は、電源１０と、吸引センサ２０と、押しボタン３０と、発光素子４０と、制御回路５０とを有する。電源１０、吸引センサ２０、押しボタン３０及び制御回路５０は、第２筒体１１２Ｘに収容される。第２筒体１１２Ｘは、所定方向Ａに沿って延びる筒状形状（例えば、円筒形状）を有する。 The power supply unit 112 has a second cylindrical body 112X that forms part of the aspirator housing 110X. The power supply unit 112 has an inlet 112A. Air flowing in from the inlet 112A is guided to the cartridge 111 (atomization means 111R) as shown in FIG. Specifically, power supply unit 112 includes power supply 10 , suction sensor 20 , push button 30 , light emitting element 40 , and control circuit 50 . The power source 10, the suction sensor 20, the push button 30 and the control circuit 50 are housed in the second cylindrical body 112X. The second tubular body 112X has a tubular shape (for example, a cylindrical shape) extending along the predetermined direction A. As shown in FIG.
　電源１０は、例えば、リチウムイオン電池である。電源１０は、香味吸引器１００の動作に必要な電力を蓄積する。例えば、電源１０は、吸引センサ２０及び制御回路５０に供給する電力を蓄積する。また、電源１０は、カートリッジ１１１（霧化手段１１１Ｒ）に供給する電力を蓄積する。 The power supply 10 is, for example, a lithium ion battery. Power source 10 stores the power required to operate flavor inhaler 100 . For example, the power supply 10 stores power to supply the suction sensor 20 and the control circuit 50 . Also, the power source 10 accumulates electric power to be supplied to the cartridge 111 (atomizing means 111R).
　吸引センサ２０は、インレット１１２Ａからアウトレット１３０Ａまで連続する吸引経路内の流体流れを検知する。吸引センサ２０は、インレット１１２Ａからアウトレット１３０Ａ側への流体流れが所定閾値以上である場合に、吸引（吸引状態）を検知する。吸引センサ２０は、インレット１１２Ａからアウトレット１３０Ａ側への流体流れが所定閾値未満である場合に、非吸引（非吸引状態）を検知する。 The suction sensor 20 detects fluid flow in a continuous suction path from the inlet 112A to the outlet 130A. The suction sensor 20 detects suction (suction state) when the fluid flow from the inlet 112A to the outlet 130A side is equal to or greater than a predetermined threshold. The suction sensor 20 detects non-suction (non-suction state) when the fluid flow from the inlet 112A to the outlet 130A side is less than a predetermined threshold.
　押しボタン３０は、香味吸引器１００の外側から内側に向けて押し込むように構成される。押しボタン３０は、香味吸引器１００の非吸口端に設けられており、非吸口端から吸口端に向かう方向（すなわち、所定方向Ａ）に押し込むように構成される。例えば、香味吸引器１００の電源が投入されていない状態において、押しボタン３０が所定回数に亘って連続的に押し込まれた場合に、香味吸引器１００の電源が投入されてもよい。一方で、香味吸引器１００の電源が投入された状態において、押しボタン３０が所定回数に亘って連続的に押し込まれた場合に、香味吸引器１００の電源が切断されてもよい。或いは、パフ動作が行われてからパフ動作が行われないまま所定時間が経過した場合に、香味吸引器１００の電源が切断されてもよい。 The push button 30 is configured to be pushed inward from the outside of the flavor inhaler 100 . The push button 30 is provided at the non-mouth end of the flavor inhaler 100 and is configured to be pushed in the direction from the non-mouth end toward the mouth end (that is, the predetermined direction A). For example, the power of the flavor inhaler 100 may be turned on when the push button 30 is continuously pushed a predetermined number of times while the power of the flavor inhaler 100 is not turned on. On the other hand, the power of the flavor inhaler 100 may be turned off when the push button 30 is continuously pushed a predetermined number of times while the power of the flavor inhaler 100 is on. Alternatively, the power source of the flavor inhaler 100 may be turned off when a predetermined time has passed since the puffing operation was performed without performing the puffing operation.
　発光素子４０は、例えば、ＬＥＤや電灯などの光源である。発光素子４０は、所定方向に沿って延びる側壁に設けられる。発光素子４０は、非吸口端の近傍の側壁に設けられることが好ましい。これによって、所定方向Ａの軸線上において非吸口端の端面のみに発光素子が設けられる場合と比べて、使用者はパフ動作中において発光素子４０の発光パターンを容易に視認することができる。発光素子４０の発光パターンは、香味吸引器１００の状態を使用者に通知するパターンである。発光素子４０は、所望量のエアロゾルを供給可能な旨を報知する報知部を構成してもよい。ここで、発光素子４０は、所望量のエアロゾルを供給可能な期間の開始から終了までの間に亘って、所望量のエアロゾルを供給可能な旨を継続的に報知してもよい。或いは、発光素子４０は、所望量のエアロゾルを供給可能でない旨を報知する報知部を構成してもよい。ここで、発光素子４０は、所望量のエアロゾルを供給可能でない期間の開始から終了までの間に亘って、所望量のエアロゾルを供給可能でない旨を継続的に報知してもよい。 The light emitting element 40 is, for example, a light source such as an LED or electric light. The light emitting element 40 is provided on a side wall extending along a predetermined direction. The light emitting element 40 is preferably provided on the side wall near the non-mouth end. As a result, the user can easily see the light emitting pattern of the light emitting element 40 during the puffing action, compared to the case where the light emitting element is provided only on the end face of the non-mouthpiece end on the axis in the predetermined direction A. The light emission pattern of the light emitting element 40 is a pattern for notifying the user of the state of the flavor inhaler 100 . The light emitting element 40 may constitute a notification unit that notifies that a desired amount of aerosol can be supplied. Here, the light emitting element 40 may continuously notify that the desired amount of aerosol can be supplied from the start to the end of the period in which the desired amount of aerosol can be supplied. Alternatively, the light emitting element 40 may constitute a notification unit that notifies that the desired amount of aerosol cannot be supplied. Here, the light emitting element 40 may continuously notify that the desired amount of aerosol cannot be supplied from the start to the end of the period in which the desired amount of aerosol cannot be supplied.
　制御回路５０は、香味吸引器１００の動作を制御する。具体的には、制御回路５０は、カートリッジ１１１（霧化手段１１１Ｒ）に対する電源出力を制御する。また、制御回路５０は、発光素子４０を制御する。 The control circuit 50 controls the operation of the flavor inhaler 100. Specifically, the control circuit 50 controls power output to the cartridge 111 (atomization means 111R). Also, the control circuit 50 controls the light emitting element 40 .
　香味付与カートリッジ１３０は、香味吸引器１００を構成する吸引器本体１１０に接続可能に構成される。香味付与カートリッジ１３０は、吸口から吸い込まれる気体（以下、空気）の流路上においてカートリッジ１１１よりも下流に設けられる。言い換えると、香味付与カートリッジ１３０は、必ずしも物理空間的にカートリッジ１１１よりも吸口側に設けられている必要はなく、カートリッジ１１１から発生するエアロゾルを吸口側に導くエアロゾル流路上においてカートリッジ１１１よりも下流に設けられていればよい。 The flavor imparting cartridge 130 is configured to be connectable to the aspirator main body 110 that constitutes the flavor aspirator 100 . The flavor imparting cartridge 130 is provided downstream of the cartridge 111 on the flow path of gas (hereinafter referred to as air) sucked from the mouthpiece. In other words, the flavor imparting cartridge 130 does not necessarily need to be physically spaced closer to the mouthpiece side than the cartridge 111, but is located downstream of the cartridge 111 on the aerosol flow path that guides the aerosol generated from the cartridge 111 toward the mouthpiece side. It is sufficient if it is provided.
　具体的には、香味付与カートリッジ１３０は、香味付与カートリッジハウジング１３１と、たばこ源１３２と、網目１３３Ａと、フィルタ１３３Ｂとを有する。また、香味付与カートリッジ１３０は、吸口に設けられるアウトレット１３０Ａを有する。 Specifically, the flavoring cartridge 130 has a flavoring cartridge housing 131, a tobacco source 132, a mesh 133A, and a filter 133B. The flavoring cartridge 130 also has an outlet 130A provided in the mouthpiece.
　香味付与カートリッジハウジング１３１は、所定方向Ａに沿って延びる筒状形状（例えば、円筒形状）を有する。香味付与カートリッジハウジング１３１は、たばこ源１３２を収容する。ここでは、香味付与カートリッジハウジング１３１は、吸引器ハウジング１１０Ｘに所定方向Ａに沿って挿入されるように構成される。 The flavor imparting cartridge housing 131 has a cylindrical shape (for example, a cylindrical shape) extending along the predetermined direction A. Flavoring cartridge housing 131 houses tobacco source 132 . Here, flavoring cartridge housing 131 is configured to be inserted along predetermined direction A into aspirator housing 110X.
　たばこ源１３２は、インレット１１２Ａからアウトレット１３０Ａまで連続する吸引経路上においてカートリッジ１１１よりもアウトレット１３０Ａ（吸口）側に設けられる。たばこ源１３２は、エアロゾル源から発生するエアロゾルにたばこ由来成分を付与する。言い換えると、たばこ源１３２によってエアロゾルに付与されるたばこ由来成分は、アウトレット１３０Ａ（吸口）に運ばれる。たばこ源１３２としては、前述した本実施形態に係るたばこ源を用いることができる。 The tobacco source 132 is provided closer to the outlet 130A (mouthpiece) than the cartridge 111 on the continuous suction path from the inlet 112A to the outlet 130A. Tobacco source 132 imparts a tobacco-derived component to the aerosol generated from the aerosol source. In other words, the tobacco-derived component imparted to the aerosol by tobacco source 132 is conveyed to outlet 130A (mouthpiece). As the tobacco source 132, the tobacco source according to this embodiment described above can be used.
　網目１３３Ａは、たばこ源１３２の上流において香味付与カートリッジハウジング１３１の開口を塞ぐように設けられている。フィルタ１３３Ｂは、たばこ源１３２の下流において香味付与カートリッジハウジング１３１の開口を塞ぐように設けられている。網目１３３Ａは、たばこ源１３２を構成する原料片が通過しない程度の粗さを有する。網目１３３Ａの粗さは、例えば、０．０７７～０．１９８ｍｍの目開きを有する。フィルタ１３３Ｂは、通気性を有する物質によって構成される。フィルタ１３３Ｂは、例えば、アセテートフィルタであることが好ましい。フィルタ１３３Ｂは、たばこ源１３２を構成する原料片が通過しない程度の粗さを有する。 The mesh 133A is provided upstream of the tobacco source 132 so as to block the opening of the flavor imparting cartridge housing 131 . Filter 133B is provided downstream of tobacco source 132 to block the opening of flavoring cartridge housing 131 . The mesh 133A has such roughness that the raw material pieces forming the tobacco source 132 cannot pass through. The mesh 133A has a mesh size of, for example, 0.077 to 0.198 mm. The filter 133B is made of a breathable material. Filter 133B is preferably an acetate filter, for example. The filter 133B has a roughness to the extent that the raw material pieces forming the tobacco source 132 do not pass through.
　以下、本実施形態を実施例により詳細に説明するが、本実施形態はこれらの実施例に限定されない。なお、作製した非燃焼加熱型香味吸引器の使用時におけるニコチン及びメンソールの送達量は、以下の方法により測定した。 Hereinafter, the present embodiment will be described in detail with examples, but the present embodiment is not limited to these examples. The delivery amounts of nicotine and menthol during use of the produced non-combustion heating type flavor inhaler were measured by the following method.
　［ニコチン及びメンソールの送達量の測定方法］
　非燃焼加熱型香味吸引器の吸口端を、成分捕集用フィルタをセットしたフィルタホルダーに差し込み、フィルタホルダー下流部を喫煙器に接続した。該喫煙器で吸引することで、非燃焼加熱型香味吸引器から放出されるエアロゾルをフィルタホルダー内に捕集した。吸引条件は、５５ｃｃ／ｐｕｆｆで３秒吸引し、３０秒間隔で５回繰り返すことで、フィルタホルダー内に５ｐｕｆｆ分のエアロゾルを捕集した。捕集後、フィルタホルダーからフィルタを取り出し、メタノールで成分を振とう抽出した後、ＧＣでニコチン及び／又はメンソール量を定量した。 [Method for measuring delivery amount of nicotine and menthol]
The mouthpiece end of the non-combustion heating type flavor inhaler was inserted into a filter holder in which a component collection filter was set, and the downstream part of the filter holder was connected to the smoking device. By inhaling with the smoking device, the aerosol emitted from the non-combustion heating flavor inhaler was collected in the filter holder. The aspiration conditions were 55 cc/puff for 3 seconds, and repeated 5 times at 30-second intervals to collect 5 puff of aerosol in the filter holder. After the collection, the filter was taken out from the filter holder, and the components were shaken and extracted with methanol, and the amount of nicotine and/or menthol was quantified by GC.
