Description
本発明は、香味発生物品及び喫煙システムに関する。
The present invention relates to flavor generating articles and smoking systems.
従来、材料の燃焼をすることなく香味等を吸引するための香味発生物品が知られている(例えば、特許文献1及び特許文献2)。このような香味発生物品は、揮発成分を含むたばこを含む香味源を有し、ヒータ等を香味源の内部に挿入することで、香味源の内部から直接加熱され得る。
Conventionally, there are known flavor-generating articles for inhaling flavor, etc. without burning materials (for example, Patent Documents 1 and 2). Such a flavor generating article has a flavor source containing tobacco containing a volatile component, and can be directly heated from inside the flavor source by inserting a heater or the like inside the flavor source.
加熱ブレード若しくは加熱ピン又はサセプタ等のヒータにより香味源を内部から加熱する、いわゆる内部加熱型の加熱式デバイスは、香味源を直接高温に加熱できる。このような内部加熱型の加熱式デバイスで香味源を効率良く加熱することが求められる。
A so-called internal heating type heating device that heats the flavor source from the inside by a heater such as a heating blade, a heating pin, or a susceptor can directly heat the flavor source to a high temperature. It is required to efficiently heat the flavor source with such an internal heating type heating device.
本発明の目的の一つは、効率よく加熱することが可能な香味発生物品及び喫煙システムを提供することである。
One of the objects of the present invention is to provide a flavor generating article and a smoking system that can be efficiently heated.
第1態様によれば、加熱により香味を発生する香味発生物品が提供される。この香味発生物品は、ヒータを挿入可能な貫通孔と、前記貫通孔を画定する筒状の弾性変形シートと、を有する。前記弾性変形シートは、その厚さ方向に弾性変形可能である。
According to the first aspect, a flavor generating article that generates flavor by heating is provided. This flavor generating article has a through hole into which a heater can be inserted, and a cylindrical elastically deformable sheet defining the through hole. The elastically deformable sheet is elastically deformable in its thickness direction.
第1態様によれば、貫通孔にヒータを挿入したときに、弾性変形シートがヒータに対して厚さ方向に弾性変形して、ヒータに接触又は接近しやすくなる。このため、弾性変形シートが香味を含む場合、又は弾性変形シートの内側に香味を含むシートが存在する場合に、ヒータに対して香味を含むシートをより接触又は接近させることができるから、香味発生物品が効率よく加熱され得る。
According to the first aspect, when the heater is inserted into the through-hole, the elastically deformable sheet is elastically deformed in the thickness direction with respect to the heater, making it easier to contact or approach the heater. Therefore, when the elastically deformable sheet contains flavor, or when the flavor-containing sheet exists inside the elastically deformable sheet, the flavor-containing sheet can be brought into closer contact with or closer to the heater, thereby generating flavor. Articles can be efficiently heated.
第2態様は、第1態様において、前記弾性変形シートは、85%以上95%以下の体積空隙率を有する、ことを要旨とする。
The gist of the second aspect is that in the first aspect, the elastically deformable sheet has a volume porosity of 85% or more and 95% or less.
第2態様によれば、香味を含むシートをよりヒータに対して適切に接触又は近接させることができる。弾性変形シートの体積空隙率が85%未満であると、弾性変形シートの反発力が強すぎ、香味発生物品を変形させ難くなる。また、この場合、香味発生物品の通気抵抗が上がりすぎる虞がある。弾性変形シートの体積空隙率が95%超であると、弾性変形シートの反発力が弱く、香味発生物品を変形させた際に、香味発生物品の内壁とヒータとの接触が弱くなり、デリバリに影響を与える虞がある。
According to the second aspect, the flavor-containing sheet can be appropriately brought into contact with or close to the heater. When the volume porosity of the elastically deformable sheet is less than 85%, the repulsive force of the elastically deformable sheet is too strong, making it difficult to deform the flavor generating article. Moreover, in this case, there is a possibility that the ventilation resistance of the flavor-generating article may be excessively increased. When the volume porosity of the elastically deformable sheet exceeds 95%, the repulsive force of the elastically deformable sheet is weak, and when the flavor-generating article is deformed, the contact between the inner wall of the flavor-generating article and the heater becomes weak, resulting in poor delivery. There is a risk of impact.
第3態様は、第1態様又は第2態様において、前記弾性変形シートは、0mmH2O以上150mmH2O以下の通気抵抗を有する、ことを要旨とする。
A gist of a third aspect is that in the first aspect or the second aspect, the elastically deformable sheet has a ventilation resistance of 0 mmH 2 O or more and 150 mmH 2 O or less.
第3態様によれば、ヒータと弾性変形シートとの間に隙間が生じなくとも、ユーザの吸引時の通気抵抗を適切にすることができる。弾性変形シートの通気抵抗が150mmH2O超であると、吸引抵抗が高くなりすぎ、ユーザが吸引に不快を感じる恐れがある。
According to the third aspect, even if there is no gap between the heater and the elastically deformable sheet, the ventilation resistance when the user sucks can be made appropriate. If the airflow resistance of the elastically deformable sheet exceeds 150 mmH 2 O, the suction resistance becomes too high, and the user may feel uncomfortable when sucking.
第4態様は、第1態様から第3態様のいずれかにおいて、前記弾性変形シートは、30g/m2以上100g/m2以下の坪量を有する非たばこシートである、ことを要旨とする。
A gist of a fourth aspect is that in any one of the first to third aspects, the elastically deformable sheet is a non-tobacco sheet having a basis weight of 30 g/m 2 or more and 100 g/m 2 or less.
第4態様によれば、香味を含むシートをよりヒータに対して適切に接触させることができる。弾性変形シートの坪量が30g/m2未満であると、直ぐに香味を出し尽くしてしまったり、弾性変形シートが薄すぎて製造過程で破れ等が起きやすくなって、製造適性が悪くなったり、ヒータ挿入時に弾性変形シートが破れたりする虞がある。弾性変形シートの坪量が100g/m2超であると、弾性変形シートを曲げ難くなり、香味発生物品10を変形させ難くなる。また、この場合、熱容量が大きくなるため、香味発生物品10の昇温が遅くなり、最初のパフが可能になるまでの時間がかかる虞がある。
According to the fourth aspect, the flavor-containing sheet can be brought into more appropriate contact with the heater. If the basis weight of the elastically deformable sheet is less than 30 g/m 2 , the flavor is quickly exhausted, or the elastically deformable sheet is too thin and is likely to break during the manufacturing process, resulting in poor production aptitude. There is a risk that the elastically deformable sheet will break when the heater is inserted. If the basis weight of the elastically deformable sheet is more than 100 g/m 2 , it becomes difficult to bend the elastically deformable sheet, and it becomes difficult to deform the flavor generating article 10 . Moreover, in this case, since the heat capacity is increased, the temperature rise of the flavor generating article 10 is slowed down, and there is a possibility that it takes time until the first puff is possible.

According to the sixth aspect, the elastically deformable sheet can be elastically deformed in its thickness direction by deforming the corrugated cross section of the non-tobacco sheet. In addition, since the non-tobacco sheet having a corrugated cross section has gaps (between waves) along its longitudinal direction, it is possible to define channels through which the flavor and the like generated in the flavor generating article pass.

第15態様によれば、弾性変形シートの変形に対してラッピングシートが適切な形状を維持することができる。ラッピングシートが50g/m2未満の坪量である場合、弾性変形シートよりも変形しやすくなり、適切な形状を維持できなくなる恐れがある。ラッピングシートが100g/m2超の坪量である場合、ラッピングシートに取り囲まれた弾性変形シートが変形しにくくなる恐れがある。
According to the fifteenth aspect, the wrapping sheet can maintain an appropriate shape against deformation of the elastically deformable sheet. If the basis weight of the wrapping sheet is less than 50 g/m 2 , it may deform more easily than the elastically deformable sheet, making it impossible to maintain an appropriate shape. If the basis weight of the wrapping sheet exceeds 100 g/m 2 , the elastically deformable sheet surrounded by the wrapping sheet may be difficult to deform.
第16態様によれば、喫煙システムが提供される。喫煙システムは、第1態様から第15態様のいずれかの香味発生物品と、前記ヒータを備える香味吸引器と、を有する。前記貫通孔の直径は、前記ヒータの挿入方向と直交する最大長さよりも小さい。

第16態様によれば、ヒータが貫通孔に挿入されることにより、貫通孔がヒータによって押し広げられ得る。これにより、香味発生物品の弾性変形シートが変形し得る。例えば、ヒータが板状のヒータである場合には、貫通孔の断面形状がヒータによって扁平に変形し、これに伴い、弾性変形シートが板状のヒータの主面に接触又は接近し得る。また、ヒータがピン状のヒータである場合には、貫通孔内にヒータが挿入されると、弾性変形シートが厚さ方向に圧縮されて、弾性変形シートがヒータの周面に接触又は接近し得る。これにより、香味発生物品が効率よく加熱され得る。
According to the sixteenth aspect, the through hole can be expanded by the heater by inserting the heater into the through hole. This can deform the elastically deformable sheet of the flavor-generating article. For example, when the heater is a plate-shaped heater, the cross-sectional shape of the through hole is flattened by the heater, and along with this, the elastically deformable sheet may contact or approach the main surface of the plate-shaped heater. Further, in the case where the heater is a pin-shaped heater, when the heater is inserted into the through hole, the elastically deformable sheet is compressed in the thickness direction, and the elastically deformable sheet contacts or approaches the peripheral surface of the heater. obtain. This allows efficient heating of the flavor-generating article.

第17態様によれば、香味発生物品が香味吸引器の開口に挿入されることで、香味発生物品が開口の形状に合わせて変形し得る。具体的には、香味発生物品は、開口の最小直径に合わせて変形されて、その断面が扁平に変形され得る。これにより、香味発生物品の弾性変形シートがヒータに接触又は接近して、香味発生物品が効率よく加熱され得る。
According to the seventeenth aspect, the flavor-generating article can be deformed according to the shape of the opening by inserting the flavor-generating article into the opening of the flavor inhaler. Specifically, the flavor-generating article can be deformed to fit the minimum diameter of the opening to flatten its cross-section. Thereby, the elastically deformable sheet of the flavor generating article contacts or approaches the heater, and the flavor generating article can be efficiently heated.

The gist of the eighteenth aspect is that in the sixteenth aspect or the seventeenth aspect, the inner peripheral length of the through-hole is equal to or longer than the outer peripheral length of the heater.
第18態様によれば、香味発生物品及び貫通孔が変形しても、ヒータと香味発生物品(貫通孔を画定する香味発生物品の内面)との間に隙間を生じさせることができるので、吸引抵抗の増加を防止し、且つ香味発生物品で発生した香味又はエアロゾルをこの隙間を通じてより確実にユーザに送達することができる。なお、ここでのヒータの外周長は、ヒータの香味発生物品に挿入される部分の中での最大の外周長さであり得る。
According to the eighteenth aspect, even if the flavor-generating article and the through-hole are deformed, a gap can be generated between the heater and the flavor-generating article (the inner surface of the flavor-generating article that defines the through-hole). An increase in resistance can be prevented and the flavor or aerosol generated in the flavor generating article can be more reliably delivered to the user through this gap. It should be noted that the outer circumference of the heater here may be the maximum outer circumference of the portion of the heater that is inserted into the flavor generating article.
第19態様は、第16態様から第18態様のいずれかにおいて、前記ヒータは、第1面及び前記第1面と対向する第2面を有する板状ヒータであり、前記板状ヒータが前記貫通孔に挿入されたとき、前記弾性変形シートと前記第1面又は前記第2面との間の距離が小さくなるように、前記弾性変形シートが変形する、ことを要旨とする。
A nineteenth aspect is any one of the sixteenth to eighteenth aspects, wherein the heater is a plate-like heater having a first surface and a second surface facing the first surface, and the plate-like heater penetrates the The gist is that the elastically deformable sheet is deformed so that the distance between the elastically deformable sheet and the first surface or the second surface is reduced when inserted into the hole.

以下、本発明の実施形態について図面を参照して説明する。以下で説明する図面において、同一の又は相当する構成要素には、同一の符号を付して重複した説明を省略する。
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals, and duplicate descriptions are omitted.
図1は、本実施形態に係る香味発生物品の概略図である。図2は、図1における矢視2-2における香味発生物品の側面図である。図1において、香味発生物品10の第1部分30は断面図で示され、第2部分20は側面図で示される。香味発生物品10は、全体としてスティック状の部品であり、加熱により香味を発生させて、香味発生物品10を吸引するユーザに香味を提供するように構成される。図1に示すように、香味発生物品10は、第1部分30と、第1部分30と長手方向に隣接する第2部分20とを有する。
FIG. 1 is a schematic diagram of the flavor-generating article according to this embodiment. FIG. 2 is a side view of the flavor generating article taken along arrow 2-2 in FIG. In FIG. 1, the first portion 30 of the flavor generating article 10 is shown in cross-section and the second portion 20 is shown in side view. The flavor generating article 10 is a stick-shaped component as a whole, and is configured to generate flavor by heating and provide the flavor to a user who inhales the flavor generating article 10 . As shown in FIG. 1, the flavor generating article 10 has a first portion 30 and a second portion 20 longitudinally adjacent to the first portion 30 .
第1部分30は、加熱により香味を発生するように構成される。図1及び図2に示すように、第1部分30は、弾性変形シート32を含む。また、第2部分20は、第1部分30で生じた香味が通過するように構成される。これにより、第1部分30で生じた香味が第2部分20において冷却され得る。香味発生物品10は、後述する香味吸引器のヒータを挿入可能な貫通孔36を有し、貫通孔36は、筒状の弾性変形シート32によって少なくとも一部が画定され得る。図2に示すように、貫通孔36及び第1部分30は、長手方向から見て略円形の断面を有する。本実施形態において、弾性変形シート32は、その厚さ方向(即ち、筒状の弾性変形シート32の径方向)に弾性変形可能である。これにより、貫通孔36にヒータを挿入したときに、弾性変形シート32がヒータに対して厚さ方向に弾性変形して、ヒータに接触又は接近しやすくなる。このため、弾性変形シート32が香味を含む場合、又は弾性変形シート32の内側に香味を含むシートが存在する場合に、ヒータに対して香味を含むシートをより接触又は接近させることができるから、香味発生物品10が効率よく加熱され得る。
The first portion 30 is configured to generate flavor by heating. As shown in FIGS. 1 and 2, the first portion 30 includes an elastically deformable sheet 32. As shown in FIG. Also, the second portion 20 is configured to allow the flavor generated in the first portion 30 to pass through. This allows the flavor produced in the first portion 30 to cool in the second portion 20 . The flavor-generating article 10 has a through-hole 36 into which a heater of a later-described flavor inhaler can be inserted. As shown in FIG. 2, the through hole 36 and the first portion 30 have a substantially circular cross-section when viewed in the longitudinal direction. In this embodiment, the elastically deformable sheet 32 is elastically deformable in its thickness direction (that is, the radial direction of the tubular elastically deformable sheet 32). As a result, when the heater is inserted into the through hole 36, the elastically deformable sheet 32 is elastically deformed in the thickness direction with respect to the heater, making it easier to contact or approach the heater. Therefore, when the elastically deformable sheet 32 contains flavor, or when a sheet containing flavor exists inside the elastically deformable sheet 32, the flavor-containing sheet can be brought into contact or closer to the heater. The flavor generating article 10 can be efficiently heated.
図1及び図2に示す例において、弾性変形シート32は、非たばこシートであってもよい。非たばこシートは、非たばこ原料をシート状に形成したものを意味し、たばこ原料を含んでもよい。具体的には、弾性変形シート32は、パルプ繊維又は不織布等の非たばこ繊維から構成され得、エアロゾル源を含んでもよい。非たばこシートに用いられる非たばこ繊維には非パルプ繊維が含まれ得る。非パルプ繊維とはパルプ繊維以外の繊維である。パルプ繊維とは、木材等の植物から取り出されたセルロース繊維の集合体であり、通常は紙の原料として用いられる。パルプ繊維としては、古紙パルプ、化学パルプ、機械パルプ等が挙げられる。
In the examples shown in FIGS. 1 and 2, the elastically deformable sheet 32 may be a non-tobacco sheet. A non-tobacco sheet means a non-tobacco material formed into a sheet, and may contain tobacco material. Specifically, the elastically deformable sheet 32 may be composed of non-tobacco fibers such as pulp fibers or non-woven fabrics, and may contain an aerosol source. Non-tobacco fibers used in non-tobacco sheets may include non-pulp fibers. Non-pulp fibers are fibers other than pulp fibers. Pulp fiber is an aggregate of cellulose fibers extracted from plants such as wood, and is usually used as a raw material for paper. Pulp fibers include waste paper pulp, chemical pulp, mechanical pulp and the like.
非たばこシートはバインダを含んでいてもよい。バインダは繊維同士等を結合するための接着剤である。バインダとしては、当該分野において公知のものを使用できる。非たばこシートは乳化剤を含んでいてもよい。乳化剤は親油性であるエアロゾル生成基材と親水性である非パルプ繊維の親和性を高める。乳化剤としては公知のものを用いることができるが、その例としては8~18のHLB値を有する乳化剤が挙げられる。
The non-tobacco sheet may contain a binder. A binder is an adhesive for binding fibers together. A binder known in the art can be used as the binder. The non-tobacco sheet may contain emulsifiers. Emulsifiers enhance the affinity between the aerosol-generating substrate, which is oleophilic, and the non-pulp fibers, which are hydrophilic. Known emulsifiers can be used, and examples thereof include emulsifiers having an HLB value of 8-18.
エアロゾル源とは、加熱により気化し冷却されてエアロゾルを生成するあるいは霧化によってエアロゾルを生成する材料である。エアロゾル源としては公知のものを用いることができるが、その例としてはグリセリン、プロピレングリコール(PG)等の多価アルコール、トリエチルシトレート(TEC)、トリアセチン等が挙げられる。このエアロゾル源は、後述するたばこシート34bにも添加され得る。
An aerosol source is a material that is vaporized by heating and then cooled to generate an aerosol, or that is atomized to generate an aerosol. Known aerosol sources can be used, and examples thereof include glycerin, polyhydric alcohols such as propylene glycol (PG), triethyl citrate (TEC), triacetin and the like. This aerosol source may also be added to the tobacco sheet 34b described below.
非たばこシートは香味発生基材を含んでいてもよい。香味発生基材は香喫味を与える材料であり、たばこ材料であることが好ましい。具体的なたばこ材料としては、乾燥したたばこ葉を刻んだもの、葉たばこ粉砕物、またはたばこ抽出物(水、有機溶媒、またはこれらの混合溶液による抽出物)等が挙げられる。葉たばこ粉砕物は、葉たばこを粉砕することにより得られる粒子である。葉たばこ粉砕物は、例えば、その平均粒径を30~120μmとすることができる。粉砕は、公知の粉砕機を用いて行うことができ、乾式粉砕でも湿式粉砕でもよい。したがって、葉たばこ粉砕物は葉たばこ粒子とも称される。本実施形態において平均粒径は、レーザ回折・散乱法により求められ、具体的にはレーザ回折式粒子径分布測定装置(例えば、堀場製作所 LA-950)を用いて測定される。また、たばこの種類は限定されず、黄色種、バーレー種、オリエント種、在来種、及び、その他のニコチアナ・タバカム系品種やニコチアナ・ルスチカ系品種等を用いることができる。非たばこシートにおける香味発生基材の量は、特に限定されないが好ましくは1~30重量%、より好ましくは10~20重量%である。
The non-tobacco sheet may contain a flavor generating base material. The flavor-generating substrate is a material that imparts flavor and taste, and is preferably a tobacco material. Specific tobacco materials include chopped dried tobacco leaves, pulverized leaf tobacco, tobacco extracts (extracts with water, organic solvents, or mixed solutions thereof), and the like. Leaf tobacco pulverized material is particles obtained by pulverizing leaf tobacco. The pulverized leaf tobacco can have, for example, an average particle size of 30 to 120 μm. Pulverization can be performed using a known pulverizer, and may be dry pulverization or wet pulverization. Leaf tobacco pulverized products are therefore also referred to as leaf tobacco particles. In the present embodiment, the average particle diameter is obtained by a laser diffraction/scattering method, and specifically measured using a laser diffraction particle size distribution analyzer (eg, Horiba LA-950). In addition, the type of tobacco is not limited, and yellow varieties, burley varieties, orient varieties, native varieties, and other Nicotiana tabacum varieties and Nicotiana rustica varieties can be used. The amount of the flavor generating base material in the non-tobacco sheet is not particularly limited, but is preferably 1 to 30% by weight, more preferably 10 to 20% by weight.
香味発生基材には香料も含まれ得る。香料とは、香りや風味を提供する物質である。香料は天然香料であってもよいし合成香料であってもよい。香料として1種類の香料を用いてもよいし複数種類の香料の混合物を用いてもよい。香料として、喫煙物品において一般に使用される任意の香料を使用することができるが、その具体例は後述する。香料は、喫煙物品が好ましい香りや風味を提供することができるような量で、非たばこシートに含むことができ、例えば、その量は非たばこシート中、好ましくは1~30重量%、より好ましくは10~20重量%である。
The flavor-generating base material may also contain a fragrance. A flavoring agent is a substance that provides an odor or flavor. The perfume may be a natural perfume or a synthetic perfume. As the perfume, one kind of perfume may be used, or a mixture of multiple kinds of perfumes may be used. Any flavor commonly used in smoking articles can be used as the flavor, specific examples of which are described below. The flavoring agent may be included in the non-tobacco sheet in an amount such that the smoking article can provide a desirable aroma or flavor, for example, the amount is preferably 1 to 30% by weight, more preferably 1 to 30% by weight of the non-tobacco sheet. is 10 to 20% by weight.

また、香味発生基材は、清涼剤または風味料を含んでもよい。当該清涼剤の種類は、特に限定されず、良好な喫味の付与の観点から、例えば、メントール、カンファー、イソプレゴール、シネオール、ハッカオイル、ペパーミントオイル、ユーカリプタスオイル、2-l-メントキシエタノール(COOLACT(登録商標)5)、3-l-メントキシプロパン-1,2-ジオール(COOLACT(登録商標)10)、l-メンチル-3-ヒドロキシブチレート(COOLACT(登録商標)20)、p-メンタン-3,8-ジオール(COOLACT(登録商標)38D)、N-(2-ヒドロキシ-2-フェニルエチル)-2-イソプロピル-5,5-ジメチルシクロヘキサン-1-カルボキサミド(COOLACT(登録商標)370)、N-(4-(シアノメチル)フェニル)-2-イソプロピル-5,5-ジメチルシクロヘキサンカルボキサミド(COOLACT(登録商標)400)、N-(3-ヒドロキシ-4-メトキシフェニル)-2-イソプロピル-5,5-ジメチルシクロヘキサンカルボキサミド、N-エチル-p-メンタン-3-カルボアミド(WS-3)、エチル-2-(p-メンタン-3-カルボキサミド)アセテ-ト(WS-5)、N-(4-メトキシフェニル)-p-メンタンカルボキサミド(WS-12)、2-イソプロピル-N,2,3-トリメチルブチラミド(WS-23)、3-l-メントキシ-2-メチルプロパン-1,2-ジオール、2-l-メントキシエタン-1-オール、3-l-メントキシプロパン-1-オール、4-l-メントキシブタン-1-オール、メンチルラクテート(FEMA3748)、メントングリセリンアセタール(FrescolatMGA、FEMA3807、FEMA3808)、2-(2-l-メンチルオキシエチル)エタノール、グリオキシル酸メンチル、2-ピロリドン-5-カルボン酸メンチル、コハク酸メンチル(FEMA3810)、N-(2-(ピリジン-2-イル)-エチル)-3-p-メンタンカルボキサミド(FEMA4549)、N-(エトキシカルボニルメチル)-p-メンタン-3-カルボキサミド、N-(4-シアノメチルフェニル)-p-メンタンカルボキサミド、及びN-(4-アミノカルボニルフェニル)-p-メンタン等が挙げられる。清涼剤は単独で、または2種以上を併用してもよい。
In addition, the flavor-generating base material may contain a cooling agent or a flavoring agent. The type of the cooling agent is not particularly limited, and from the viewpoint of imparting a good smoking taste, for example, menthol, camphor, isopulegol, cineole, peppermint oil, peppermint oil, eucalyptus oil, 2-l-menthoxyethanol (COOLACT ( registered trademark) 5), 3-l-menthoxypropane-1,2-diol (COOLACT® 10), l-menthyl-3-hydroxybutyrate (COOLACT® 20), p-menthane- 3,8-diol (COOLACT® 38D), N-(2-hydroxy-2-phenylethyl)-2-isopropyl-5,5-dimethylcyclohexane-1-carboxamide (COOLACT® 370), N-(4-(cyanomethyl)phenyl)-2-isopropyl-5,5-dimethylcyclohexanecarboxamide (COOLACT® 400), N-(3-hydroxy-4-methoxyphenyl)-2-isopropyl-5, 5-dimethylcyclohexanecarboxamide, N-ethyl-p-menthane-3-carboamide (WS-3), ethyl-2-(p-menthane-3-carboxamide) acetate (WS-5), N-(4- methoxyphenyl)-p-menthanecarboxamide (WS-12), 2-isopropyl-N,2,3-trimethylbutyramide (WS-23), 3-l-menthoxy-2-methylpropane-1,2-diol, 2-l-menthoxyethan-1-ol, 3-l-menthoxypropan-1-ol, 4-l-menthoxybutan-1-ol, menthyl lactate (FEMA3748), menthone glycerin acetal (Frescolat MGA, FEMA3807, FEMA3808), 2-(2-l-menthyloxyethyl)ethanol, menthyl glyoxylate, menthyl 2-pyrrolidone-5-carboxylate, menthyl succinate (FEMA3810), N-(2-(pyridin-2-yl)- ethyl)-3-p-menthanecarboxamide (FEMA4549), N-(ethoxycarbonylmethyl)-p-menthane-3-carboxamide, N-(4-cyanomethylphenyl)-p-menthanecarboxamide, and N-(4- aminocarbonylphenyl)-p-menthane and the like. A cooling agent may be used alone or in combination of two or more.
当該風味料の種類は、特に限定されず、良好な喫味の付与の観点から、例えば、甘味料(糖(グルコース、フルクトース、異性化糖、カラメル等))、酸味料(有機酸等)、その他呈味料(うま味、苦味、塩味を呈する素材等)等が挙げられる。その他、任意で、脂質(ワックス、ろう、脂肪酸(短鎖、中鎖、長鎖脂肪酸等))を添加し得る。
The type of flavoring agent is not particularly limited, and from the viewpoint of imparting a good taste, for example, sweeteners (sugars (glucose, fructose, isomerized sugar, caramel, etc.)), acidulants (organic acids, etc.), and others. Flavoring agents (materials exhibiting umami, bitterness, salty taste, etc.) and the like. In addition, optionally, lipids (waxes, waxes, fatty acids (short-chain, medium-chain, long-chain fatty acids, etc.)) can be added.
たばこ刻中に香料、清涼剤、及び風味料が含まれる場合、一態様においてこれらの合計の含有量は、特に限定されないが、良好な喫味の付与の観点から、通常10000ppm以上であり、好ましくは20000ppm以上であり、より好ましくは25000ppm以上であり、また、通常70000ppm以下であり、好ましくは50000ppmであり、より好ましくは40000ppm以下であり、さらに好ましくは33000ppm以下である。また、別態様において前記合計量は、好ましくは2重量%以上、より好ましくは5重量%以上であり、好ましくは20重量%以下、より好ましくは10重量%以下である。
When the cut tobacco contains a flavoring agent, a cooling agent, and a flavoring agent, the total content thereof is not particularly limited in one aspect, but from the viewpoint of imparting a good smoking taste, it is usually 10000 ppm or more, preferably It is 20,000 ppm or more, more preferably 25,000 ppm or more, and usually 70,000 ppm or less, preferably 50,000 ppm, more preferably 40,000 ppm or less, and still more preferably 33,000 ppm or less. In another aspect, the total amount is preferably 2% by weight or more, more preferably 5% by weight or more, and preferably 20% by weight or less, more preferably 10% by weight or less.
弾性変形シート32は、85%以上95%以下の体積空隙率を有することが好ましい。これにより、香味を含むシート(弾性変形シート32又は後述するたばこシート34b)をよりヒータに対して適切に接触又は近接させることができる。弾性変形シート32の体積空隙率が85%未満であると、弾性変形シートの反発力が強すぎ、香味発生物品を変形させ難くなる。また、この場合、香味発生物品の通気抵抗が上がりすぎる虞がある。弾性変形シート32の体積空隙率が95%超であると、弾性変形シートの反発力が弱く、香味発生物品を変形させた際に、香味発生物品の内壁とヒータとの接触が弱くなり、デリバリに影響を与える虞がある。
The elastically deformable sheet 32 preferably has a volume porosity of 85% or more and 95% or less. As a result, the flavor-containing sheet (elastic deformation sheet 32 or tobacco sheet 34b, which will be described later) can be appropriately brought into contact with or close to the heater. If the volume porosity of the elastically deformable sheet 32 is less than 85%, the repulsive force of the elastically deformable sheet is too strong, making it difficult to deform the flavor generating article. Moreover, in this case, there is a possibility that the ventilation resistance of the flavor-generating article may be excessively increased. When the volume porosity of the elastically deformable sheet 32 is more than 95%, the repulsive force of the elastically deformable sheet is weak, and when the flavor generating article is deformed, the contact between the inner wall of the flavor generating article and the heater is weak, resulting in delivery. may affect
また、弾性変形シート32は、0mmH2O以上150mmH2O以下の通気抵抗を有することが好ましい。これにより、ヒータと弾性変形シート32との間に隙間が生じなくとも、ユーザの吸引時の通気抵抗を適切にすることができる。弾性変形シート32の通気抵抗が150mmH2O超であると、吸引抵抗が高くなりすぎ、ユーザが吸引に不快を感じる恐れがある。なお、ここでの弾性変形シート32の通気抵抗とは、弾性変形シート32の長さ方向、即ち、図1における左右方向(空気の流れ方向)の通気抵抗を意味する。
In addition, the elastically deformable sheet 32 preferably has a ventilation resistance of 0 mmH2O or more and 150 mmH2O or less. As a result, even if there is no gap between the heater and the elastically deformable sheet 32, the ventilation resistance when the user inhales can be made appropriate. If the airflow resistance of the elastically deformable sheet 32 exceeds 150 mmH 2 O, the suction resistance becomes too high, and the user may feel uncomfortable when sucking. The ventilation resistance of the elastically deformable sheet 32 here means the ventilation resistance in the longitudinal direction of the elastically deformable sheet 32, that is, in the left-right direction (air flow direction) in FIG.
弾性変形シート32は、厚さ方向において所定の硬さを有することが好ましい。硬さをコントロールすることで、香味発生物品10を変形させやすく、且つ香味発生物品10とヒータとが密着し、加熱効率を向上させることができる。
The elastic deformation sheet 32 preferably has a predetermined hardness in the thickness direction. By controlling the hardness, the flavor-generating article 10 can be easily deformed, and the flavor-generating article 10 and the heater can be brought into close contact with each other to improve the heating efficiency.
弾性変形シート32は、30g/m2以上100g/m2以下の坪量を有する非たばこシートであることが好ましい。これにより、香味を含むシートをよりヒータに対して適切に接触させることができる。弾性変形シート32の坪量が30g/m2未満であると、直ぐに香味を出し尽くしてしまったり、弾性変形シートが薄すぎて製造過程で破れ等が起きやすくなって、製造適性が悪くなったり、ヒータ挿入時に弾性変形シートが破れたりする虞がある。弾性変形シート32の坪量が100g/m2超であると、性変形シートを曲げ難くなり、香味発生物品10を変形させ難くなる。また、この場合、熱容量が大きくなるため、香味発生物品10の昇温が遅くなり、最初のパフが可能になるまでの時間がかかる虞がある。
The elastically deformable sheet 32 is preferably a non-tobacco sheet having a basis weight of 30 g/m 2 or more and 100 g/m 2 or less. As a result, the flavor-containing sheet can be brought into more appropriate contact with the heater. If the basis weight of the elastically deformable sheet 32 is less than 30 g/m 2 , the flavor is quickly exhausted, or the elastically deformable sheet is too thin to easily break during the manufacturing process, resulting in poor production aptitude. Also, the elastically deformable sheet may break when the heater is inserted. If the basis weight of the elastically deformable sheet 32 exceeds 100 g/m 2 , it becomes difficult to bend the elastically deformable sheet, making it difficult to deform the flavor generating article 10 . Moreover, in this case, since the heat capacity is increased, the temperature rise of the flavor generating article 10 is slowed down, and there is a possibility that it takes time until the first puff is possible.
上述したように、弾性変形シート32は、エアロゾル源又は香味発生基材を担持する非たばこシートであることが好ましい。これにより、弾性変形シート32がヒータに接触又は接近することにより効率よく弾性変形シート32が加熱されて、エアロゾル又は香味を発生させることができる。
As described above, the elastically deformable sheet 32 is preferably a non-tobacco sheet carrying an aerosol source or flavor-generating substrate. As a result, the elastically deformable sheet 32 is efficiently heated by contacting or approaching the heater, and aerosol or flavor can be generated.
図1及び図2に示すように、香味発生物品10は、香味発生シート34を有することが好ましい。図示の例では、香味発生シート34は、弾性変形シート32の内側に位置して、筒状に形成され、弾性変形シート32と共に貫通孔36の少なくとも一部を画定する。これにより、弾性変形シート32が変形して弾性変形シート32がヒータに接触又は接近することで、弾性変形シート32の内側に位置する香味発生シート34をヒータに接触又は接近させることができる。その結果、効率よく香味発生シート34が加熱されて、エアロゾル又は香味を発生させることができる。これに限らず、本実施形態では、貫通孔36が、弾性変形シート32又は香味発生シート34の内面により画定され得る。これにより、貫通孔36にヒータ120を挿入したときに、弾性変形シート32又は香味発生シート34の内面がヒータ120に直接接触し得るので、弾性変形シート32又は香味発生シート34が効率よく加熱され得る。
As shown in FIGS. 1 and 2, the flavor-generating article 10 preferably has a flavor-generating sheet 34 . In the illustrated example, the flavor-generating sheet 34 is positioned inside the elastically deformable sheet 32 , is formed in a tubular shape, and defines at least a portion of the through hole 36 together with the elastically deformable sheet 32 . As a result, the elastically deformable sheet 32 is deformed to contact or approach the heater, thereby allowing the flavor generating sheet 34 located inside the elastically deformable sheet 32 to contact or approach the heater. As a result, the flavor generating sheet 34 can be efficiently heated to generate an aerosol or flavor. Not limited to this, in the present embodiment, the through holes 36 may be defined by the inner surface of the elastically deformable sheet 32 or the flavor generating sheet 34 . As a result, when the heater 120 is inserted into the through-hole 36, the inner surface of the elastically deformable sheet 32 or the flavor generating sheet 34 can come into direct contact with the heater 120, so that the elastically deformable sheet 32 or the flavor generating sheet 34 can be efficiently heated. obtain.
図2に示すように、香味発生シート34は、エアロゾル源又は香味発生基材を担持する非たばこシート34aを含むことができる。これにより、非たばこシート34aのエアロゾル源又は香味発生基材が効率よく加熱されて、エアロゾル又は香味等を発生させることができる。なお、非たばこシート34aに担持されるエアロゾル源又は香味発生基材は、弾性変形シート32が担持し得る、上述したエアロゾル源又は香味発生基材とすることができる。
As shown in FIG. 2, the flavor generating sheet 34 can include a non-tobacco sheet 34a carrying an aerosol source or flavor generating substrate. As a result, the aerosol source or flavor-generating substrate of the non-tobacco sheet 34a can be efficiently heated to generate an aerosol, flavor, or the like. The aerosol source or flavor-generating substrate carried by the non-tobacco sheet 34a can be the above-described aerosol source or flavor-generating substrate that the elastically deformable sheet 32 can carry.
また、図2に示すように、香味発生シート34は、たばこシート34bを含むことができる。これにより、たばこシート34bが効率よく加熱されて、エアロゾル又は香味を発生させることができる。図2に示す例では、たばこシート34bは非たばこシート34aの内側に位置するが、たばこシート34bが非たばこシート34aの外側に位置してもよい。
Also, as shown in FIG. 2, the flavor generating sheet 34 can include a tobacco sheet 34b. As a result, the tobacco sheet 34b can be efficiently heated to generate an aerosol or flavor. In the example shown in FIG. 2, the tobacco sheet 34b is positioned inside the non-tobacco sheet 34a, but the tobacco sheet 34b may be positioned outside the non-tobacco sheet 34a.
たばこシート34bは、例えばたばこ(香味発生基材の一例に相当する)と、多価アルコール(エアロゾル源の一例に相当する)等を含み得る。多価アルコールには、グリセリン、プロピレングリコール、ソルビトール、キシリトール及びエリスリトールが含まれ得る。これらの多価アルコールは、単独で、または2種以上を組み合わせて、たばこシート34bに使用することができる。これらの多価アルコールは、上述した弾性変形シート32にも添加され得る。たばこシート34bは、粉状のたばこ及び多価アルコールにバインダを混ぜることでシート状に形成され得る。バインダとしては、例えば、グアーガム、キサンタンガム、CMC(カルボキシメチルセルロース)、CMC-Na(カルボキシメチルセルロースのナトリウム塩)、プルラン及びヒドロキシプロピルセルロース(HPC)、メチルセルロース、ヒドロキシルメチルセルロース等を使用することができる。このバインダは、上述した弾性変形シート32にも添加され得る。
The tobacco sheet 34b may contain, for example, tobacco (corresponding to an example of a flavor-generating base material) and polyhydric alcohol (corresponding to an example of an aerosol source). Polyhydric alcohols may include glycerin, propylene glycol, sorbitol, xylitol and erythritol. These polyhydric alcohols can be used singly or in combination of two or more for the tobacco sheet 34b. These polyhydric alcohols can also be added to the elastically deformable sheet 32 described above. The tobacco sheet 34b can be formed into a sheet shape by mixing powdered tobacco and polyhydric alcohol with a binder. As the binder, for example, guar gum, xanthan gum, CMC (carboxymethylcellulose), CMC-Na (sodium salt of carboxymethylcellulose), pullulan and hydroxypropylcellulose (HPC), methylcellulose, hydroxylmethylcellulose and the like can be used. This binder can also be added to the elastically deformable sheet 32 described above.
また、たばこシート34bには、パルプが加えられてもよい。パルプは、たばこシート34bの強度を向上させ得る。他方、たばこシート34bにはパルプが加えられなくてもよい。パルプを使用しない場合、その分だけたばこシート34bにおけるたばこの割合が増加するので喫味の向上が期待される。
Pulp may also be added to the tobacco sheet 34b. Pulp may improve the strength of the tobacco sheet 34b. On the other hand, the tobacco sheet 34b may be free of pulp. If pulp is not used, the percentage of tobacco in the tobacco sheet 34b is increased by that amount, so an improvement in smoking taste is expected.
たばこシート34bに添加され得るバインダの重量%は、例えば、たばこシート34bの重量に対して、好ましくは0%以上60%以下、より好ましくは0%以上10%以下である。たばこシート34bは、例えば、多価アルコールが5%から40%、たばこが50%から90%、バインダが0%から10%、パルプが0%から10%の配合割合(重量パーセント)を有し得る。また、たばこシート34bには、乳酸、パルミチン酸、又は安息香酸等の酸を加えてもよい。
The weight percentage of the binder that can be added to the tobacco sheet 34b is, for example, preferably 0% or more and 60% or less, more preferably 0% or more and 10% or less, relative to the weight of the tobacco sheet 34b. The tobacco sheet 34b has a compounding ratio (weight percent) of, for example, 5% to 40% polyhydric alcohol, 50% to 90% tobacco, 0% to 10% binder, and 0% to 10% pulp. obtain. In addition, an acid such as lactic acid, palmitic acid, or benzoic acid may be added to the tobacco sheet 34b.
図2に示すように、香味発生シート34は、たばこシート34bと非たばこシート34aとを含むことができる。これに限らず、香味発生シート34は、たばこシート34bと非たばこシート34aのいずれか一方のみを含むことができる。
As shown in FIG. 2, the flavor generating sheet 34 can include a tobacco sheet 34b and a non-tobacco sheet 34a. However, the flavor-generating sheet 34 may include only one of the tobacco sheet 34b and the non-tobacco sheet 34a.
図3は、図1に示した矢視3-3における第2部分20の断面図である。図3に示すように、第2部分20は、筒状のラッピングシート21と、ラッピングシート21の内部に位置する第1ストッパ22と、を有する。本実施形態において、ラッピングシート21の坪量は、50g/m2以上150g/m2以下であることが好ましく、50g/m2以上100g/m2以下であることがより好ましい。ラッピングシート21は、図2に示すように弾性変形シート32の外側を取り囲むことが好ましい。具体的には、ラッピングシート21は、第2部分20から第1部分30まで延長することが好ましい。これにより、弾性変形シート32の変形に対してラッピングシート21が適切な形状を維持することができる。ラッピングシート21が50g/m2未満の坪量である場合、弾性変形シート32よりも変形しやすくなり、適切な形状を維持できなくなる恐れがある。ラッピングシート21が100g/m2超の坪量である場合、ラッピングシート21に取り囲まれた弾性変形シート32が変形しにくくなる恐れがある。
FIG. 3 is a cross-sectional view of the second portion 20 taken along line 3-3 shown in FIG. As shown in FIG. 3 , the second portion 20 has a tubular wrapping sheet 21 and a first stopper 22 located inside the wrapping sheet 21 . In the present embodiment, the basis weight of the wrapping sheet 21 is preferably 50 g/m 2 or more and 150 g/m 2 or less, more preferably 50 g/m 2 or more and 100 g/m 2 or less. The wrapping sheet 21 preferably surrounds the outside of the elastically deformable sheet 32 as shown in FIG. Specifically, the wrapping sheet 21 preferably extends from the second portion 20 to the first portion 30 . Thereby, the wrapping sheet 21 can maintain an appropriate shape against the deformation of the elastically deformable sheet 32 . If the basis weight of the wrapping sheet 21 is less than 50 g/m 2 , it may deform more easily than the elastically deformable sheet 32 and may not maintain its proper shape. If the basis weight of the wrapping sheet 21 exceeds 100 g/m 2 , the elastically deformable sheet 32 surrounded by the wrapping sheet 21 may be difficult to deform.
第1ストッパ22は、弾性変形シート32が第1部分30から第2部分20に向かって移動することを防止することができる。具体的には、本実施形態では、長手方向から見て、第2部分20の第1ストッパ22の少なくとも一部が、弾性変形シート32と同一半径上に位置する。言い換えれば、第1ストッパ22の少なくとも一部は、弾性変形シート32と長手方向において接触するように位置する。これにより、ヒータが貫通孔36に挿入されたときに、ヒータによって第2部分20に向かう方向に弾性変形シート32に力が加えられても、第1ストッパ22が弾性変形シート32に接触して、弾性変形シート32の移動が防止され得る。このため、ヒータ挿入時に香味発生物品10が破壊されることが抑制され得る。本実施形態においては、第1ストッパ22は、その両端が筒状のラッピングシート21の内面の異なる位置に接続され、その端部間の長さがラッピングシート21の直径よりも長い紙であり得る。これに限らず、第1ストッパ22は、弾性変形シート32が第1部分30から第2部分20に向かって移動することを防止できる任意の形態を採り得る。
The first stopper 22 can prevent the elastic deformation sheet 32 from moving from the first portion 30 toward the second portion 20 . Specifically, in this embodiment, at least a portion of the first stopper 22 of the second portion 20 is positioned on the same radius as the elastically deformable sheet 32 when viewed in the longitudinal direction. In other words, at least part of the first stopper 22 is positioned to contact the elastically deformable sheet 32 in the longitudinal direction. As a result, when the heater is inserted into the through hole 36 , even if the heater applies force to the elastically deformable sheet 32 in the direction toward the second portion 20 , the first stopper 22 does not come into contact with the elastically deformable sheet 32 . , the movement of the elastically deformable sheet 32 can be prevented. Therefore, it is possible to prevent the flavor generating article 10 from being destroyed when the heater is inserted. In this embodiment, the first stopper 22 can be a piece of paper whose both ends are connected to different positions on the inner surface of the cylindrical wrapping sheet 21 and whose length between the ends is longer than the diameter of the wrapping sheet 21. . Not limited to this, the first stopper 22 can take any form that can prevent the elastically deformable sheet 32 from moving from the first portion 30 toward the second portion 20 .
図4Aは、他の実施形態に係る香味発生物品10の側面図である。図4Aは、図1に示した矢視2-2における側面図を示す。香味発生物品10は、弾性変形シート32が第1部分30から第2部分20の反対側に向かって移動することを防止する第2ストッパ38を有することが好ましい。第2ストッパ38は、第1部分30の第2部分20とは反対側の位置において、長手方向から見て第2ストッパ38の少なくとも一部が弾性変形シート32と同一半径上に位置する。言い換えれば、第2ストッパ38の少なくとも一部は、第1部分30の第2部分20とは反対側の位置において、弾性変形シート32と長手方向において接触するように位置する。これにより、貫通孔36からヒータを抜いたときに、弾性変形シート32が第2部分20の反対側に向かって移動すること、即ち弾性変形シート32がヒータと共に第1部分30から抜けることを抑制することができる。このため、貫通孔36からヒータを抜いても、弾性変形シート32を第1部分30に残すことができるので、使用後の香味発生物品10を容易に廃棄処理することができる。
FIG. 4A is a side view of a flavor generating article 10 according to another embodiment. FIG. 4A shows a side view on arrow 2-2 shown in FIG. The flavor generating article 10 preferably has a second stopper 38 that prevents the elastically deformable sheet 32 from moving from the first portion 30 toward the opposite side of the second portion 20 . The second stopper 38 is positioned on the opposite side of the first portion 30 to the second portion 20, and at least a portion of the second stopper 38 is positioned on the same radius as the elastically deformable sheet 32 when viewed in the longitudinal direction. In other words, at least a portion of the second stopper 38 is positioned so as to contact the elastically deformable sheet 32 in the longitudinal direction at a position on the opposite side of the first portion 30 to the second portion 20 . This prevents the elastically deformable sheet 32 from moving toward the opposite side of the second portion 20 when the heater is removed from the through hole 36, that is, the elastically deformable sheet 32 is prevented from coming out of the first portion 30 together with the heater. can do. Therefore, even if the heater is pulled out from the through hole 36, the elastically deformable sheet 32 can remain in the first portion 30, so that the used flavor generating article 10 can be easily discarded.
図4Aに示す例では、第2ストッパ38は、弾性変形シート32の端面及び貫通孔36を覆う封止シートである。具体的には、第2ストッパ38は、香味発生物品10の第1部分30の径方向に延び、その略中央部にミシン目38aが形成され得る。図4Bは、ヒータが挿入された後の香味発生物品10の概略図である。図4Bにおいて、第1部分30は断面図で示される。図4Bに示されるように、ヒータが貫通孔36に挿入されると、第2ストッパ38はヒータによって、例えばミシン目38aに沿って切断され得る。第2ストッパ38を破るように貫通孔36にヒータを挿入することで、第2ストッパ38を弾性変形シート32の端面に位置させながら、香味発生物品10がヒータによって加熱され得る。このため、使用後に貫通孔36からヒータを引き抜くときに、弾性変形シート32の端面に位置する第2ストッパ38によって、弾性変形シート32がヒータと共に第1部分30から抜けることが抑制され得る。第2ストッパ38は、例えばセンターホールフィルタ等、弾性変形シート32が第1部分30から第2部分20の反対側に向かって移動することを防止できる任意の形態を採り得る。
In the example shown in FIG. 4A, the second stopper 38 is a sealing sheet that covers the end surface of the elastically deformable sheet 32 and the through hole 36 . Specifically, the second stopper 38 may extend in the radial direction of the first portion 30 of the flavor generating article 10 and may be formed with a perforation 38a substantially in the center thereof. FIG. 4B is a schematic illustration of the flavor generating article 10 after the heater has been inserted. In FIG. 4B, the first portion 30 is shown in cross-section. As shown in FIG. 4B, when the heater is inserted into the through hole 36, the second stopper 38 can be cut by the heater, for example along perforations 38a. By inserting the heater into the through hole 36 so as to break the second stopper 38 , the flavor generating article 10 can be heated by the heater while the second stopper 38 is positioned on the end surface of the elastically deformable sheet 32 . Therefore, when the heater is pulled out from the through-hole 36 after use, the second stopper 38 positioned at the end face of the elastically deformable sheet 32 can prevent the elastically deformable sheet 32 from coming out of the first portion 30 together with the heater. The second stopper 38 can take any form that can prevent the elastically deformable sheet 32 from moving from the first portion 30 toward the opposite side of the second portion 20, such as a center hole filter.
次に、香味発生物品10を加熱するための香味吸引器について説明する。図5は香味吸引器100の要部をヒータ120の幅方向について示す断面図である。図6は、香味吸引器100の要部をヒータ120の厚み方向について示す断面図である。香味吸引器100は、香味発生物品10と共に喫煙システムを構成し得る。図5及び図6に示すように、香味吸引器100は、筐体110とヒータ120とを備える。筐体110は、一端に開口112を有し、開口112を介して、開口112に挿入される香味発生物品10の少なくとも一部を収容する。筐体110は、例えば、樹脂製であり、特に、PC(ポリカーボネート)、ABS(Acrylonitrile-Butadiene-Styrene)樹脂、PEEK(ポリエーテルエーテルケトン)または複数種類のポリマーを含有するポリマーアロイ等、あるいは、アルミ等の金属で形成され得る。ここで、筐体110は、筐体110の長手方向に直交する断面における断面積が、開口112近傍において最も小さくなるように構成されている。
Next, the flavor inhaler for heating the flavor generating article 10 will be described. FIG. 5 is a cross-sectional view showing the main part of the flavor inhaler 100 in the width direction of the heater 120. As shown in FIG. FIG. 6 is a cross-sectional view showing the main part of the flavor inhaler 100 in the thickness direction of the heater 120. As shown in FIG. Flavor inhaler 100 may constitute a smoking system together with flavor generating article 10 . As shown in FIGS. 5 and 6, the flavor inhaler 100 includes a housing 110 and a heater 120. As shown in FIGS. The housing 110 has an opening 112 at one end and accommodates at least a portion of the flavor generating article 10 inserted into the opening 112 through the opening 112 . The housing 110 is, for example, made of resin, particularly PC (polycarbonate), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), a polymer alloy containing a plurality of types of polymers, or the like, or It can be made of metal such as aluminum. Here, the housing 110 is configured such that the cross-sectional area of the cross section perpendicular to the longitudinal direction of the housing 110 is the smallest in the vicinity of the opening 112 .
また、筐体110は、整形ガイド114と抑えリブ116とを有する。整形ガイド114は、開口112に設けられ、筐体110に挿入される香味発生物品10の断面形状を変形させる。抑えリブ116は、筐体110の内周面に設けられ、筐体110に挿入される香味発生物品10をヒータ120に向けて付勢し、香味発生物品10の形状を変形させる。整形ガイド114及び抑えリブ116の詳細な構成及び香味発生物品10を変形させる機能については、後述する。
The housing 110 also has a shaping guide 114 and a restraining rib 116 . The shaping guide 114 is provided in the opening 112 and deforms the cross-sectional shape of the flavor generating article 10 inserted into the housing 110 . The restraining ribs 116 are provided on the inner peripheral surface of the housing 110 and bias the flavor generating article 10 inserted into the housing 110 toward the heater 120 to deform the shape of the flavor generating article 10 . The detailed configuration of the shaping guides 114 and the restraining ribs 116 and the function of deforming the flavor generating article 10 will be described later.
図示の例では、ヒータ120は、筐体110に収容された香味発生物品10に挿入され、香味発生物品10を内部から加熱する平板状のPTC(Positive Temperature Coefficient)ヒータである。また、ヒータ120は、筐体110に挿入される香味発生物品10の形状を、ヒータ120の形状に沿って変形させる。ヒータ120の香味発生物品10を変形させる機能については、後述する。ここで、整形ガイド114、抑えリブ116及びヒータ120は、筐体110に収容された後の香味発生物品10の形状を、筐体110に収容される前の香味発生物品10の形状から変形させるものである。なお、ヒータ120は、板状であればよく、本実施形態のように抵抗加熱式のヒータ120に限らず、例えば、サセプタとして用いられる、誘導コイルによって誘導加熱されるヒータであってもよい。
In the illustrated example, the heater 120 is a flat PTC (Positive Temperature Coefficient) heater that is inserted into the flavor generating article 10 housed in the housing 110 and heats the flavor generating article 10 from the inside. Also, the heater 120 deforms the shape of the flavor generating article 10 inserted into the housing 110 along the shape of the heater 120 . The function of the heater 120 to deform the flavor generating article 10 will be described later. Here, the shaping guide 114, the restraining rib 116, and the heater 120 deform the shape of the flavor generating article 10 after being housed in the housing 110 from the shape of the flavor generating article 10 before being housed in the housing 110. It is. Note that the heater 120 may be plate-shaped, and is not limited to the resistance heating type heater 120 as in the present embodiment.
続いて、香味発生物品10を香味吸引器100に収容するとき、すなわち香味発生物品10を筐体110の一端側から他端側に向けて挿入するときの香味発生物品10と筐体110及びヒータ120との関係について説明する。図7から図9は、香味発生物品10が香味吸引器100に収容される状態を示す断面図である。なお、図7から図9では、香味発生物品10の弾性変形シート32及び香味発生シート34を、1つの環状シート33として示す。
Subsequently, when housing the flavor generating article 10 in the flavor inhaler 100, that is, when inserting the flavor generating article 10 from one end side of the housing 110 toward the other end side, the flavor generating article 10, the housing 110, and the heater 120 will be described. 7 to 9 are cross-sectional views showing how the flavor generating article 10 is accommodated in the flavor inhaler 100. FIG. 7 to 9 show the elastically deformable sheet 32 and the flavor generating sheet 34 of the flavor generating article 10 as one annular sheet 33. FIG.
図7は、香味発生物品10が整形ガイド114を通過するときの状態を、ヒータ120の幅方向の断面、及び整形ガイド114の入口部118における、筐体110の長手方向に直交する断面について示す。図8は、香味発生物品10が抑えリブ116を通過するときの状態を、ヒータ120の幅方向の断面、並びに抑えリブ116の中間部及び他端側端部における、筐体110の長手方向に直交する断面について示す。図9は、香味発生物品10が筐体110の所定の収容位置に収容された状態を、ヒータ120の幅方向の断面、及びヒータ120の他端側端部近傍における、筐体110の長手方向に直交する断面について示す。
FIG. 7 shows a state in which the flavor generating article 10 passes through the shaping guide 114 in a cross section in the width direction of the heater 120 and a cross section perpendicular to the longitudinal direction of the housing 110 at the entrance portion 118 of the shaping guide 114. . FIG. 8 shows the state when the flavor-generating article 10 passes through the restraining rib 116 in a cross section in the width direction of the heater 120 and in the longitudinal direction of the housing 110 at the intermediate portion and the other end of the restraining rib 116. An orthogonal cross section is shown. FIG. 9 shows a state in which the flavor-generating article 10 is housed in a predetermined housing position in the housing 110, and shows a cross section in the width direction of the heater 120 and a longitudinal direction of the housing 110 in the vicinity of the other end of the heater 120. is shown for a cross section orthogonal to .
図7に示すように、整形ガイド114は、テーパ部117と、入口部118とを有する。テーパ部117は、筐体110の一端側に向けて拡管されるように構成され、香味吸引器100への香味発生物品10の挿入を案内する。香味吸引器100の開口112の最大直径は、香味発生物品10の最大直径より大きく、開口112の最小直径は、香味発生物品10の最小直径より小さいことが好ましい。この場合、香味発生物品10が香味吸引器100の開口112に挿入されることで、香味発生物品10が開口112の形状に合わせて変形し得る。具体的には、香味発生物品10は、開口112の最小直径に合わせて変形されて、その断面が扁平に変形され得る。これにより、香味発生物品10の弾性変形シート32がヒータ120に接触又は接近して、香味発生物品10が効率よく加熱され得る。なお、ここでの開口112は、香味発生物品10が挿入される香味吸引器100の開口112うち、最小の断面積を有する部分であり得る。具体的には、ここでの開口112は、図7に示す例では入口部118であり得る。入口部118は、楕円形の断面を有し、長径が筐体110に収容された後の香味発生物品10の直径よりも大きく、短径が筐体110に収容される前の香味発生物品10の直径とほぼ同じ長さになるように構成されてもよい。また、入口部118は、内周長が香味発生物品10の外周長よりも短くなるように構成されてもよい。
As shown in FIG. 7 , the shaping guide 114 has a tapered portion 117 and an entrance portion 118 . The tapered portion 117 is configured to expand toward one end of the housing 110 and guide the insertion of the flavor generating article 10 into the flavor inhaler 100 . Preferably, the maximum diameter of the opening 112 of the flavor inhaler 100 is greater than the maximum diameter of the flavor generating article 10 and the minimum diameter of the opening 112 is less than the minimum diameter of the flavor generating article 10 . In this case, by inserting the flavor generating article 10 into the opening 112 of the flavor inhaler 100 , the flavor generating article 10 can be deformed according to the shape of the opening 112 . Specifically, the flavor generating article 10 can be deformed to match the minimum diameter of the opening 112 to flatten its cross section. Thereby, the elastically deformable sheet 32 of the flavor generating article 10 contacts or approaches the heater 120, and the flavor generating article 10 can be efficiently heated. It should be noted that the opening 112 here may be a portion having the smallest cross-sectional area of the opening 112 of the flavor inhaler 100 into which the flavor generating article 10 is inserted. Specifically, the opening 112 here can be the inlet 118 in the example shown in FIG. The inlet portion 118 has an elliptical cross-section, a major axis larger than the diameter of the flavor generating article 10 after being accommodated in the housing 110, and a minor axis being larger than the flavor generating article 10 before being accommodated in the housing 110. may be configured to be approximately the same length as the diameter of the In addition, the inlet portion 118 may be configured such that the inner peripheral length is shorter than the outer peripheral length of the flavor generating article 10 .
図8に示すように、ヒータ120は、先鋭形状を有し、他端側に向かうにつれて幅が広がるように構成されている。これにより、香味発生物品10が整形ガイド114を通過して挿入されるにつれて、香味発生物品10の形状がヒータ120の形状に沿って変形される。具体的には、ヒータ120は、第1面120a及び第1面120aと対向する第2面120bを有する板状ヒータであり、図8に示すように、ヒータ120が貫通孔36に挿入されたとき、弾性変形シート32と第1面120a又は第2面120bとの間の距離が小さくなるように、弾性変形シート32が変形する。これにより、弾性変形シート32が変形して、弾性変形シート32がヒータ120の第1面120a又は第2面120bに接触又は接近するので、香味発生物品10が効率よく加熱され得る。
As shown in FIG. 8, the heater 120 has a sharp shape and is configured so that its width increases toward the other end. Thereby, the shape of the flavor generating article 10 is deformed along the shape of the heater 120 as the flavor generating article 10 is inserted through the shaping guide 114 . Specifically, the heater 120 is a plate heater having a first surface 120a and a second surface 120b facing the first surface 120a. As shown in FIG. At this time, the elastically deformable sheet 32 is deformed such that the distance between the elastically deformable sheet 32 and the first surface 120a or the second surface 120b is reduced. As a result, the elastically deformable sheet 32 is deformed and contacts or approaches the first surface 120a or the second surface 120b of the heater 120, so that the flavor generating article 10 can be efficiently heated.
香味発生物品10の貫通孔36の直径が、ヒータ120の挿入方向と直交する最大長さよりも小さいことが好ましい。この場合、図8に示すように、ヒータ120が貫通孔36に挿入されることにより、貫通孔36がヒータ120によって押し広げられ得る。これにより、香味発生物品10の弾性変形シート32が変形し得る。図示の例のように、ヒータ120が板状である場合には、貫通孔36の断面形状がヒータ120によって扁平に変形し、これに伴い、弾性変形シート32が板状のヒータ120の主面に接触又は接近し得る。また、ヒータ120がピン状である場合には、貫通孔36内にヒータ120が挿入されると、弾性変形シート32が厚さ方向に圧縮されて、弾性変形シート32がヒータ120の周面に接触又は接近し得る。これにより、香味発生物品10が効率よく加熱され得る。また、ヒータ120が香味発生物品10を押し広げることで、香味発生物品10の脱落を防止することができる。
It is preferable that the diameter of the through hole 36 of the flavor generating article 10 is smaller than the maximum length perpendicular to the insertion direction of the heater 120 . In this case, as shown in FIG. 8 , the through hole 36 can be expanded by the heater 120 by inserting the heater 120 into the through hole 36 . Thereby, the elastically deformable sheet 32 of the flavor generating article 10 can be deformed. As in the illustrated example, when the heater 120 is plate-shaped, the cross-sectional shape of the through hole 36 is flattened by the heater 120 , and the elastically deformable sheet 32 is deformed along the main surface of the plate-shaped heater 120 . can come in contact with or approach In addition, when the heater 120 is pin-shaped, when the heater 120 is inserted into the through hole 36 , the elastically deformable sheet 32 is compressed in the thickness direction, and the elastically deformable sheet 32 adheres to the peripheral surface of the heater 120 . can touch or come close. Thereby, the flavor-generating article 10 can be efficiently heated. In addition, the heater 120 spreads the flavor-generating article 10, thereby preventing the flavor-generating article 10 from coming off.
抑えリブ116は、ヒータ120の厚み方向に沿って筐体110の内周面に設けられ、互いに対向する一対のテーパ面により構成されている(図6参照)。また、抑えリブ116は、筐体110の長手方向について、ヒータ120の幅が徐々に広がる領域と重なるように配置されている。ここで、抑えリブ116は、筐体110の他端側に向けて突出距離が徐々に長くなるように構成され、ヒータ120の幅が最大になる位置で、突出距離が最大になるように構成されている。このとき、テーパ面間の長さは、香味発生物品10の直径よりも小さくなるように構成されている。これにより、香味発生物品10が抑えリブ116を通過するとき、ヒータ120の幅方向に押し広げられた香味発生物品10を、抑えリブ116がヒータ120の厚み方向に付勢することで、香味発生物品10が扁平形状に変形される。また、抑えリブ116が香味発生物品10を付勢することで、香味発生物品10の脱落を防止することができる。
The restraining rib 116 is provided on the inner peripheral surface of the housing 110 along the thickness direction of the heater 120, and is composed of a pair of tapered surfaces facing each other (see FIG. 6). In addition, the restraining rib 116 is arranged so as to overlap the region where the width of the heater 120 gradually widens in the longitudinal direction of the housing 110 . Here, the restraining rib 116 is configured such that the protrusion distance gradually increases toward the other end side of the housing 110, and the protrusion distance is maximized at the position where the width of the heater 120 is maximized. It is At this time, the length between the tapered surfaces is configured to be smaller than the diameter of the flavor generating article 10 . As a result, when the flavor-generating article 10 passes through the pressing rib 116, the pressing rib 116 biases the flavor-generating article 10, which has been pushed out in the width direction of the heater 120, in the thickness direction of the heater 120, thereby generating the flavor. Article 10 is deformed into a flattened shape. In addition, the pressing rib 116 urges the flavor-generating article 10, thereby preventing the flavor-generating article 10 from coming off.
香味発生物品10の貫通孔36の内周長は、ヒータ120の外周長以上であることが好ましい。これにより、図9に示すように香味発生物品10及び貫通孔36が変形しても、ヒータ120と香味発生物品10(貫通孔36を画定する香味発生物品10の内面)との間に隙間を生じさせることができるので、吸引抵抗の増加を防止し、且つ香味発生物品10で発生した香味又はエアロゾルをこの隙間を通じてより確実にユーザに送達することができる。
The inner peripheral length of the through hole 36 of the flavor generating article 10 is preferably equal to or longer than the outer peripheral length of the heater 120 . As a result, even if the flavor generating article 10 and the through hole 36 are deformed as shown in FIG. Therefore, an increase in suction resistance can be prevented, and the flavor or aerosol generated by the flavor generating article 10 can be more reliably delivered to the user through this gap.
図10は、他の実施形態に係る香味発生物品10の側面図である。図10は、図1に示した矢視2-2における香味発生物品の側面図を示す。図10に示す香味発生物品10は、図1及び図2に示した香味発生物品10と比べて、弾性変形シート32の構造が異なる。具体的には、図10に示す香味発生物品10の弾性変形シート32は、長手方向から見て波形断面を有する非たばこシートである。図示の例では、非たばこシートの波形断面が変形することで、弾性変形シート32がその厚さ方向に弾性変形することができる。また、波形断面の非たばこシートは、その長手方向に沿った隙間(波と波の間)を有するので、香味発生物品10で生じた香味等が通過する流路を画定することができる。図10に示す例では、香味発生シート34は、たばこシート34bのみを有する。
FIG. 10 is a side view of a flavor generating article 10 according to another embodiment. FIG. 10 shows a side view of the flavor generating article on arrow 2-2 shown in FIG. The flavor-generating article 10 shown in FIG. 10 differs from the flavor-generating article 10 shown in FIGS. 1 and 2 in the structure of the elastically deformable sheet 32 . Specifically, the elastically deformable sheet 32 of the flavor generating article 10 shown in FIG. 10 is a non-tobacco sheet having a wavy cross-section when viewed from the longitudinal direction. In the illustrated example, the elastically deformable sheet 32 can be elastically deformed in its thickness direction by deforming the corrugated cross section of the non-tobacco sheet. In addition, since the non-tobacco sheet with a corrugated cross section has gaps (between waves) along its longitudinal direction, it is possible to define channels through which the flavor and the like generated in the flavor generating article 10 pass. In the example shown in FIG. 10, the flavor generating sheet 34 has only the tobacco sheet 34b.
