Description
本発明は、電子的に制御されるヒーター等の熱源を備えた加熱式芳香具に装着されて加熱されることによってエアロゾル及び芳香を生成する、エアロゾルフォーマ、芳香原材、及び、結合剤等を含有する被加熱芳香発生基材の集合体である被加熱芳香発生源と、その長手方向に支持部材、冷却部材、及び、フィルターの少なくともいずれか一つを備えるマウスピースとを連接した被加熱芳香カートリッジにおいて、マウスピースが必要とする機能に有する支持部材に関し、及び、その支持部材を備えた被加熱芳香カートリッジを提供するものである。 The present invention relates to a heated aroma generating source, which is an assembly of heated aroma generating substrates containing an aerosol former, aroma source material, and binder, etc., which is attached to a heated aroma device equipped with a heat source such as an electronically controlled heater and heated to generate aerosol and aroma, and a mouthpiece equipped with at least one of a support member, a cooling member, and a filter in the longitudinal direction of the heated aroma generating source, in a heated aroma cartridge. The present invention relates to a support member having the functions required by the mouthpiece, and provides a heated aroma cartridge equipped with the support member.
特に、本発明は、マウスピースに求められる機能の中でも、被加熱芳香カートリッジの加熱式芳香具への装着時及び喫煙時における被加熱芳香発生基材及び被加熱芳香発生源を安定して支持する機能、加熱により被加熱芳香発生基材から発生するエアロゾルフォーマ及び芳香原材の揮発成分を冷却する機能、並びに、それらの揮発成分が抵抗なく通過する機能を備えた支持部材に関し、その支持部材を備えた被加熱芳香カートリッジを提供することができる。 In particular, the present invention relates to a support member that, among the functions required of a mouthpiece, has the function of stably supporting the heated aroma-generating substrate and the heated aroma-generating source when the heated aroma cartridge is attached to a heated aroma device and when smoking, the function of cooling the volatile components of the aerosol former and aroma raw material generated from the heated aroma-generating substrate when heated, and the function of allowing these volatile components to pass through without resistance, and it is possible to provide a heated aroma cartridge equipped with this support member.
従来、上記「被加熱芳香発生基材」は、「エアロゾル形成基材」と呼称されてきた。しかし、加熱することによって、エアロゾルを生成するエアロゾルフォーマと共に、芳香原材や芳香剤の香り成分も揮発され、エアロゾルの煙と芳香原材や芳香剤の香りを喫煙によって楽しむことから、本発明においては、「被加熱芳香発生基材」と呼称する。これに基づき、従来の呼称である、「エアロゾル形成体」（エアロゾル形成基材の集合体）、「電子タバコカートリッジ」、及び、「加熱式喫煙具」を、それぞれ、「被加熱芳香発生源」、「被加熱芳香カートリッジ」、及び、「加熱式芳香具」と呼称する。 The above-mentioned "heated aroma-generating substrate" has traditionally been called an "aerosol-forming substrate". However, when heated, the aroma components of the aroma raw materials and aromatics are volatilized along with the aerosol former that generates the aerosol, and the aerosol smoke and the aroma of the aroma raw materials and aromatics are enjoyed by smoking, so in this invention, it is called a "heated aroma-generating substrate". Based on this, the conventional names "aerosol-forming body" (an assembly of aerosol-forming substrates), "electronic cigarette cartridge", and "heated smoking device" are called "heated aroma-generating source", "heated aroma cartridge", and "heated aroma device", respectively.
近年、タバコの禁煙が、職場や飲食店等の人が集う空間に幅広く普及する傾向に従って、タバコを燃焼する火炎式喫煙の喫煙者数が減少するのに対し、エアロゾルを生成するエアロゾルフォーマ、ナス科タバコ属のタバコ植物を含む芳香原材を含有する、被加熱芳香発生基材の集合体である被加熱芳香発生源を備えた被加熱芳香カートリッジを、ヒーター等の熱源によって伝達された熱によって加熱する加熱式喫煙の喫煙者数が急激に増加している。 In recent years, as smoking bans have become more widespread in places where people gather, such as workplaces and restaurants, the number of smokers who use flame-based smoking, which burns tobacco, is decreasing, whereas the number of smokers who use heated smoking, which uses heated aroma cartridges that are equipped with a heated aroma generating source, which is an assembly of heated aroma generating substrates containing an aerosol former that generates an aerosol and aroma raw materials including tobacco plants of the genus Nicotiana, family Solanaceae, and that are heated by heat transferred from a heat source such as a heater, is rapidly increasing.
従来の火炎式喫煙の場合、タバコの燃焼によって、喫煙者の視覚的欲求を満足させる煙、喫煙者がタバコに依存する根源となるニコチン、そして、無数の芳香成分を十分に発生するため、愛好者数は極めて多かった。しかし、少なくとも燃焼するための６００℃を超える温度が必要であり、喫煙時には最高９００℃に達することがあり、火炎式喫煙の有害物質の発生量は極めて多く、健康志向の現在においては、受動喫煙を問題視する非喫煙者だけでなく、愛好者自身からも火炎式喫煙を敬遠する傾向が極めて顕著となっている。 In the case of traditional flame smoking, the number of enthusiasts was extremely large because the burning of tobacco produces smoke that satisfies the smoker's visual desires, nicotine that is the root cause of the smoker's addiction to tobacco, and a myriad of aromatic compounds. However, a temperature of at least 600°C is required for combustion, and can reach a maximum of 900°C during smoking, and flame smoking produces a very large amount of harmful substances, so in today's health-conscious world, there is a very clear tendency for enthusiasts, as well as non-smokers who are concerned about passive smoking, to shy away from flame smoking.
これに対し、加熱式喫煙によれば、タバコの葉の熱分解が開始する程度の温度である２００～３５０℃程度で喫煙できる上、タバコの葉以外の芳香原材が含まれているため、燃焼による有害物質の発生を防止できるばかりでなく、熱分解による有害物質の発生も低減される。そのため、加熱式喫煙を一層楽しむことを可能にする様々な技術開発が活発に行われている（例えば、特許文献１～１１）。 In contrast, heated smoking allows smoking at temperatures of around 200-350°C, the temperature at which tobacco leaves begin to decompose thermally, and contains aromatic materials other than tobacco leaves, which not only prevents the generation of harmful substances due to combustion, but also reduces the generation of harmful substances due to thermal decomposition. For this reason, various technologies that make heated smoking even more enjoyable are being actively developed (for example, Patent Documents 1-11).
このような加熱式喫煙のメカニズムは、加熱式喫煙具、被加熱芳香カートリッジ等の形態によって異なるが、ヒーターであるブレードを熱源とする加熱式芳香具に加熱芳香カートリッジを装着して喫煙する典型的な例を用い説明する。 The mechanism of such heated smoking varies depending on the form of the heated smoking device, heated aroma cartridge, etc., but we will explain it using a typical example of smoking by attaching a heated aroma cartridge to a heated aroma device that uses a heater blade as a heat source.
被加熱芳香カートリッジは、熱源から長手方向に、被加熱芳香発生源とマウスピースとがこの順に連接され構成されている。このマウスピースは、支持部材、冷却部材、及び、フィルターから少なくとも一つが選択されるが、複数用いる場合には、熱源から長手方向に、支持部材、冷却部材、及び、フィルターがこの順に連接され形成されるのが一般的である（特許文献１～１１）。 The heated aroma cartridge is configured by connecting a heated aroma generating source and a mouthpiece in this order in the longitudinal direction from the heat source. This mouthpiece is made of at least one selected from a support member, a cooling member, and a filter, but when multiple members are used, it is common for them to be formed by connecting a support member, a cooling member, and a filter in this order in the longitudinal direction from the heat source (Patent Documents 1 to 11).
被加熱芳香発生基材は、グリセリンやプロピレングリコール等のエアロゾルフォーマという沸点が約１５０～３００℃の有機溶媒と、芳香成分を有するタバコ植物を含む各種非タバコ植物や芳香剤とを、多糖類等の結合剤で塊状物としたものを成形加工したものである。喫煙に際しては、芳香カートリッジが、加熱要素を備えた加熱式芳香具のチャンバーに装着されると同時に、この被加熱芳香発生源に加熱要素が挿入される。その後、電子的に制御された加熱源により約２００～３５０℃に加熱されて、エアロゾルフォーマの揮発物（蒸気）並びにタバコ植物を含む各種非タバコ植物及び芳香剤の芳香成分の揮発物が生成される。 The heated aroma generating substrate is a mixture of an aerosol former such as glycerin or propylene glycol, an organic solvent with a boiling point of approximately 150-300°C, various non-tobacco plants including tobacco plants that contain aroma components, and aroma agents, which are formed into a mass using a binder such as polysaccharides. When smoking, the aroma cartridge is attached to the chamber of a heated aroma device equipped with a heating element, and at the same time, the heating element is inserted into this heated aroma generating source. It is then heated to approximately 200-350°C by an electronically controlled heating source, generating volatiles (vapor) from the aerosol former, as well as volatiles of various non-tobacco plants including tobacco plants and aroma components from the aroma agents.
マウスピースを構成する、支持部材、冷却部材、及び、フィルターには、それぞれ、次に示すような機能を有している（特許文献７～１１）。 The support member, cooling member, and filter that make up the mouthpiece each have the following functions (Patent Documents 7 to 11).
支持部材は、芳香カートリッジを加熱式芳香具に装着する際に、被加熱芳香発生基材及び被加熱芳香発生源を支持し、装着時及び喫煙時の被加熱芳香発生基材及び被加熱芳香発生源の破損やマウスピース側への移動の防止を主たる役割も果たすと共に、被加熱芳香発生基材が加熱されて生成する揮発物の流路となっており、揮発物が支持部材を通過する際の煙（核）の発生に大きな影響を及ぼす冷却部材の役割も果たしている（特許文献１１）。 The support member supports the heated aroma-generating substrate and the heated aroma-generating source when the aroma cartridge is attached to the heated aroma device, and plays a major role in preventing the heated aroma-generating substrate and the heated aroma-generating source from being damaged or moving toward the mouthpiece when the substrate is attached or when smoking. It also serves as a flow path for volatile matter generated when the heated aroma-generating substrate is heated, and also serves as a cooling member that has a significant effect on the generation of smoke (core) as the volatile matter passes through the support member (Patent Document 11).
冷却部材は、被加熱芳香発生基材が加熱されて生成する揮発物を積極的に冷却するための流路であり、支持部材以上に、冷却効果が高いと考えられる、揮発物との接触面積が大きい多孔質体によって形成されていることが多い（特許文献７、９、１０、及び、１１）が、有害物質を吸着する能力を有するフィルターの役割も果たしている場合がある（特許文献９）。 The cooling member is a flow path for actively cooling the volatiles generated when the heated aroma-generating substrate is heated, and is often made of a porous material with a large contact area with the volatiles, which is thought to have a greater cooling effect than the support member (Patent Documents 7, 9, 10, and 11), but may also act as a filter capable of adsorbing harmful substances (Patent Document 9).
フィルターは、揮発物や煙に含まれる有害物質等を濾過することができるセルロースアセテート繊維の束から形成された紙巻きタバコ同様のフィルターや物質吸着能に優れた細孔構造を有する炭素材料等が用いられる（特許文献７～１１）。 The filters used are similar to those used in cigarettes, made from bundles of cellulose acetate fibers that can filter out volatile matter and harmful substances contained in smoke, or made from carbon materials with pore structures that have excellent substance adsorption capabilities (Patent Documents 7 to 11).
このように、加熱式喫煙のメカニズムを要約すると、エアロゾルフォーマの揮発物が、支持部材や冷却部材を通過して冷却され生成する煙と、タバコ植物を含む各種非タバコ植物や芳香剤が揮発した芳香成分とを吸引して喫煙が楽しまれるのである。 To summarize the mechanism of heated smoking, the smoke generated when the volatiles in the aerosol former pass through a support member and a cooling member and are cooled, and the aromatic components volatilized by various non-tobacco plants, including tobacco plants, and aromatic agents are inhaled to enjoy smoking.
特に、エアロゾルフォーマの揮発物が冷却されて煙を生成する現象は、蒸気から液滴が形成される現象で、局所的な熱力学的相変化が現出する核生成現象の一つであることは興味深い。この核生成現象は、日常生活におけるコップや窓ガラスに付着する水滴、雲及び降雨の生成メカニズム、環境科学に関わる大気中におけるエアロゾル形成メカニズム、工場、病院等の蒸気を用いたプロセス、並びに、溶液から形成される結晶等において重要な意義があるため、古くから様々な理論的及び実験的研究が行われてきた（非特許文献１～８）。従って、被加熱芳香カートリッジを加熱式芳香具に装着して行う喫煙に関する開発は、核生成現象を利用したものであり、これまでの理論的及び実験的研究結果に基づいて行うことができるものと考えられる。 In particular, the phenomenon in which the volatile matter in the aerosol former cools to produce smoke is a phenomenon in which droplets are formed from vapor, and is interesting in that it is one of the nucleation phenomena in which a local thermodynamic phase change occurs. This nucleation phenomenon has important significance in the mechanisms of the formation of water droplets that adhere to cups and window panes in daily life, clouds and rainfall, the mechanism of aerosol formation in the atmosphere related to environmental science, processes that use steam in factories and hospitals, and crystals formed from solutions, and has been the subject of various theoretical and experimental research since ancient times (Non-Patent Documents 1-8). Therefore, the development of smoking by attaching a heated aroma cartridge to a heating aroma device utilizes the nucleation phenomenon and is considered to be possible based on the results of theoretical and experimental research to date.
この核生成現象と密接な関係にあるのが、エアロゾルフォーマの揮発物である蒸気が通過する流路となっているマウスピースである。特に、支持部材及び冷却部材は、核生成現象による煙を生成する場であり、蒸気が通過する流路でもあるため、支持部材及び冷却部材における煙の生成メカニズムは、核生成現象に流体力学に基づいた現象を合わせて考える必要がある（非特許文献８～１１）。 Closely related to this nucleation phenomenon is the mouthpiece, which acts as a passageway for the vapor, a volatile product of the aerosol former. In particular, the support member and cooling member are the site where smoke is generated by the nucleation phenomenon and are also the passageway through which the vapor passes, so the smoke generation mechanism in the support member and cooling member must be considered in terms of both the nucleation phenomenon and phenomena based on fluid mechanics (Non-Patent Documents 8-11).
そして、支持部材及び冷却部材における煙の生成メカニズムは、支持部材及び冷却部材設計上に大きな影響を及ぼすため、支持部材及び冷却部材における、エアロゾルフォーマの揮発物の核生成現象及び流れの状態について考える。 The mechanism of smoke generation in the support and cooling members has a significant impact on the design of the support and cooling members, so we consider the nucleation phenomenon and flow state of the volatile matter of the aerosol former in the support and cooling members.
まず、エアロゾルフォーマの揮発物の冷却による煙（核）生成、すなわち、エアロゾルの生成を、従来の熱力学に基づく核生成メカニズムから総合的に考えると、（１）気相中の均質凝縮核生成、及び、（２）壁面状の不均質凝縮核生成の二つの生成が考えられる（非特許文献１、４、及び、７）。 First, when considering smoke (nuclei) generation by cooling volatiles in an aerosol former, i.e., aerosol generation, from the perspective of conventional nucleation mechanisms based on thermodynamics, two types of generation can be considered: (1) homogeneous condensation nucleation in the gas phase, and (2) heterogeneous condensation nucleation on a wall surface (Non-Patent Documents 1, 4, and 7).
また、壁面の濡れ性によって核生成メカニズムは異なるが、上記（２）壁面状の不均質凝縮核生成による一次核生成、及び、上記（１）気相中の均質凝縮核生成である二次核生成の二段階で核生成が生じているものと考えられる。 In addition, the nucleation mechanism differs depending on the wettability of the wall surface, but it is believed that nucleation occurs in two stages: (2) primary nucleation due to heterogeneous condensation nucleation on the wall surface, and (1) secondary nucleation, which is homogeneous condensation nucleation in the gas phase.
特に、二次核生成の均質凝縮核は、一次核生成の不均質凝縮核よりも小さく、二次核生成数が、一次核生成数よりも多く、芳香カートリッジが生成する煙の量及び大きさと密接に係わるものと推測される。そして、この二次核生成数は、冷却速度が増加する程、また、蒸気の流れが乱流である程増加するので、それに伴い、核の平均粒子径が低下するため、芳香カートリッジが生成する煙の量及び大きさに大きな影響を与える。 In particular, the homogeneous condensation nuclei of secondary nucleation are smaller than the heterogeneous condensation nuclei of primary nucleation, and the number of secondary nuclei is greater than the number of primary nuclei, which is presumably closely related to the amount and size of smoke produced by the fragrance cartridge. The number of secondary nuclei increases as the cooling rate increases and the vapor flow becomes more turbulent, and the average particle size of the nuclei decreases accordingly, greatly affecting the amount and size of smoke produced by the fragrance cartridge.
一方、一次核生成は、蒸気の壁面との濡れ性が高い程、核生成が生じやすく、芳香カートリッジの流路となる支持部材及び冷却部材の材質の影響を受けるものと考えられる。 On the other hand, primary nucleation is more likely to occur the more the steam wets the wall surface, and is thought to be influenced by the materials of the support and cooling members that form the flow path of the aroma cartridge.
次いで、流体力学に基づいた現象については、連続の式、ベルヌーイの定理、レイノルズ数等から明らかなように、流路を形成する支持部材や冷却部材の構造によって流体である被加熱芳香発生基材の揮発物の流速、流れ方、及び、冷却速度等の影響を強く受ける。例えば、流路の形状は、揮発物の流速や流れ方に大きく影響し、細い管を流れる揮発物は、流速や冷却速度が大きく、乱流になりやすいため、核生成現象が生じやすいものと考えられる（非特許文献８～１１）。 Next, with regard to phenomena based on fluid mechanics, as is clear from the equation of continuity, Bernoulli's theorem, Reynolds number, etc., the flow rate, flow manner, and cooling rate of the volatiles of the heated aroma-generating substrate, which is a fluid, are strongly influenced by the structure of the support members and cooling members that form the flow path. For example, the shape of the flow path has a significant effect on the flow rate and flow manner of the volatiles, and volatiles flowing through thin tubes have high flow rates and cooling rates and are prone to turbulence, which is thought to make nucleation phenomena more likely to occur (Non-Patent Documents 8-11).
このように、加熱式喫煙における煙の生成メカニズムを、核生成現象という熱力学的要素と流体の状態を示す流体力学的要素とから検討すると、その煙の生成に及ぼす支持部材及び冷却部材の構造及び材質が、煙の生成に大きな影響及ぼすことが分かる。 In this way, when the mechanism of smoke generation in heated smoking is examined from the perspective of the thermodynamic element of the nucleation phenomenon and the fluid dynamic element that indicates the state of the fluid, it is clear that the structure and materials of the support and cooling members that affect the generation of the smoke have a significant impact on the generation of the smoke.
しかし、従来技術のマウスピース、特に、支持部材及び冷却部材は、煙が核生成現象によって生成するものであるという熱力学及び気体の流路であるという流体力学に基づいた設計がなされていないため、構造が複雑で、喫煙者の好み及び操作に適した喫煙を可能とするものは提供されてこなかった（非特許文献８～１０）。 However, the mouthpieces of the prior art, particularly the support member and cooling member, are not designed based on thermodynamics, which is that smoke is generated by a nucleation phenomenon, and on fluid dynamics, which is that they are gas flow paths, so they have a complex structure and have not been provided with a design that allows smokers to smoke in a way that suits their preferences and operation (Non-Patent Documents 8-10).
その結果として、被加熱芳香カートリッジを加熱式芳香具への装着時及び喫煙時における被加熱芳香発生基材及び被加熱芳香発生源の破損や移動等を防止する機能を有する支持部材と、エアロゾルフォーマの揮発物からエアロゾルを生成する冷却部材とを、被加熱芳香カートリッジに分離して配設する必要があった（非特許文献８～１０）。 As a result, it was necessary to separately provide a support member, which has the function of preventing damage or movement of the heated aroma generating substrate and the heated aroma generating source when the heated aroma cartridge is attached to the heated aroma device and when smoking, and a cooling member, which generates an aerosol from the volatile matter of the aerosol former, on the heated aroma cartridge (Non-Patent Documents 8 to 10).
加熱されてエアロゾル及び芳香の成分となる揮発物を生成する被加熱芳香発生基材の集合体である被加熱芳香発生源を上流側に、少なくとも支持部材を備えたマウスピースを下流側に配設して長手方向に連接される被加熱芳香カートリッジにおいて、従来のマウスピースを構成する支持部材及び冷却部材は、煙が核生成現象によって生成するものであるという熱力学及び気体の流路であるという流体力学に基づいた設計がなされていないため、構造が複雑で、喫煙者の好み及び操作に適した喫煙を可能とするものは提供されてこなかった。その結果として、被加熱芳香カートリッジを加熱式芳香具への装着時及び喫煙時における被加熱芳香発生基材及び被加熱芳香発生源の破損や移動等を防止する支持部材と、エアロゾルフォーマの揮発物からエアロゾルを生成する冷却部材とを、被加熱芳香カートリッジに分離して配設する必要があった。 In a heated aroma cartridge that is connected in the longitudinal direction, a heated aroma generating source, which is an assembly of heated aroma generating substrates that are heated to generate volatiles that become aerosol and aroma components, is arranged upstream, and a mouthpiece equipped with at least a support member is arranged downstream. Conventional support and cooling members that make up mouthpieces are not designed based on thermodynamics, which states that smoke is generated by a nucleation phenomenon, and fluid dynamics, which states that it is a gas flow path, so that the structure is complex and no products that enable smoking suited to the smoker's preferences and operation have been provided. As a result, it has been necessary to separately arrange in the heated aroma cartridge a support member that prevents damage or movement of the heated aroma generating substrate and heated aroma generating source when the heated aroma cartridge is attached to a heated aroma device and when smoking, and a cooling member that generates aerosol from volatiles in the aerosol former.
そこで、本発明者は、このような加熱式タバコの煙の生成が、蒸気から液滴が形成される核生成現象であり、支持部材及び冷却部材の流路を流れる蒸気の流体力学的現象の影響を受けるという観点から、芳香カートリッジを構成するマウスピースを再検討した。その結果、被加熱芳香発生基材及び被加熱芳香発生源の破損や移動を防止し、喫煙者にとって心地よい煙及び芳香を味わうことができるためには、適切な構造の流路を有する支持部材が存在することを見出し、本発明の完成に至った。 The inventors therefore reexamined the mouthpiece that constitutes the aroma cartridge from the viewpoint that the generation of smoke from such heated tobacco is a nucleation phenomenon in which droplets are formed from steam, and is influenced by the hydrodynamic phenomenon of the steam flowing through the flow paths of the support member and cooling member. As a result, they discovered that there exists a support member with a flow path of an appropriate structure that can prevent damage or movement of the heated aroma-generating substrate and the heated aroma-generating source, and allow smokers to enjoy pleasant smoke and aroma, leading to the completion of the present invention.
すなわち、本発明は、被加熱芳香カートリッジを喫煙者が吸引する際の気流の流れの方向を基準として、加熱されてエアロゾル及び芳香の成分となる揮発物を生成する被加熱芳香発生基材の集合体である被加熱芳香発生源を上流側に、少なくとも支持部材を備えたマウスピースを下流側に配設して長手方向に連接される被加熱芳香カートリッジにおいて、支持部材が、少なくとも、被加熱芳香発生基材及び被加熱芳香発生源の破損や移動等を防止する支持部と、揮発物を通過し冷却する流路とを備え、支持部材の外周が形成する被加熱芳香カートリッジの長手方向に垂直な断面の面積に対する、流路の外周が形成する被加熱芳香カートリッジの長手方向に垂直な断面の面積の割合を空孔率と定義したとき、空孔率が異なる少なくとも二つ以上の流路を備えていることを特徴とする支持部材である。 That is, the present invention relates to a heated aroma cartridge that is connected in the longitudinal direction with respect to the direction of airflow when a smoker inhales through the heated aroma cartridge, with a heated aroma generating source, which is an assembly of heated aroma generating substrates that are heated to generate volatiles that become aerosol and aroma components, on the upstream side and a mouthpiece equipped with at least a support member on the downstream side, the support member at least comprises a support section that prevents damage or movement of the heated aroma generating substrates and the heated aroma generating source, and a flow path that passes through and cools the volatiles, and the support member is characterized by comprising at least two or more flow paths with different porosity, where the porosity is defined as the ratio of the area of the cross section perpendicular to the longitudinal direction of the heated aroma cartridge formed by the outer periphery of the flow path to the area of the cross section perpendicular to the longitudinal direction of the heated aroma cartridge formed by the outer periphery of the support member.
そして、このような空孔率が、約１～７０％の範囲にある流路を備えていることが好ましく、二つ以上の流路の最小空孔率と最大空孔率の差が、約１９～６９％であることがより好ましい。 It is preferable that the flow paths have a porosity in the range of about 1 to 70%, and it is even more preferable that the difference between the minimum and maximum porosity of two or more flow paths is about 19 to 69%.
このような構成とすることによって、被加熱芳香発生基材の集合体である被加熱芳香発生源を面で支持することが可能な面積の支持部が形成されるため、被加熱芳香カートリッジをブレード型熱源等が備えられた加熱式芳香具に装着する際に、被加熱芳香発生基材及び被加熱芳香発生源の破損及び移動等を防止することができる。また、喫煙時における喫煙者の吸引においても、被加熱芳香発生源が支持部材から受ける応力が低減され、被加熱芳香発生源の破損及び移動等を防止することができる。 By configuring in this way, a support portion is formed with an area capable of supporting the heated aroma generating source, which is an assembly of heated aroma generating substrates, on a surface, and therefore damage and movement, etc. of the heated aroma generating substrate and heated aroma generating source can be prevented when the heated aroma cartridge is attached to a heated aroma device equipped with a blade-type heat source or the like. In addition, when the smoker inhales while smoking, the stress that the heated aroma generating source receives from the support member is reduced, preventing damage and movement, etc. of the heated aroma generating source.
このような被加熱芳香発生基材及び被加熱芳香発生源の破損及び移動の原因は、被加熱芳香発生源を構成する被加熱芳香発生基材が、エアロゾルフォーマ、加熱により芳香成分が揮発するタバコ植物や各種植物、芳香剤、及び、これらを結着するための多糖類やセルロース繊維等の結合剤等の組成物から成形加工されるものであるという、加熱式喫煙のメカニズムを実現するための材料構成に由来している。このような組成物から成形加工された、角柱状、円柱状、及び、粒状等の被加熱芳香発生基材は、やや粘性を有し、塑性変形する塊状物で脆いため、僅かな応力によって破損してしまうのである。また、被加熱芳香発生源は、通常、被加熱芳香発生基材ラッピング部材で被加熱芳香発生基材が巻装されて成形されるが、このような物性の被加熱芳香発生基材を強く巻装すると、被加熱芳香発生基材が破壊されるという問題と共に、加熱時の揮発物の流路を閉塞するという問題があり、空隙を確保した巻装状態にあることも、上述した破損及び移動の原因となっている。 The cause of the damage and movement of such heated aroma-generating substrates and heated aroma-generating sources is due to the material composition for realizing the mechanism of heated smoking, in which the heated aroma-generating substrate that constitutes the heated aroma-generating source is molded from a composition including an aerosol former, tobacco plants and various other plants that volatilize aromatic components when heated, aromatic agents, and binders such as polysaccharides and cellulose fibers for binding these. The heated aroma-generating substrates, such as rectangular columns, cylinders, and granules, molded from such compositions are slightly viscous and brittle lumps that undergo plastic deformation, so they are damaged by even the slightest stress. In addition, heated aroma-generating sources are usually molded by wrapping the heated aroma-generating substrate with a heated aroma-generating substrate wrapping member, but if a heated aroma-generating substrate with such physical properties is wrapped tightly, there is a problem that the heated aroma-generating substrate is destroyed and the flow path of the volatile matter when heated is blocked, and the wrapping state that ensures air gaps is also a cause of the damage and movement described above.
従って、空孔率を約７０％以上にすると、支持部の断面積が低減し、被加熱芳香発生基材及び被加熱芳香発生源を面で支持することが困難となり、被加熱芳香カートリッジ装着時及び喫煙時におけるこれらの破損及び移動を防止することが困難となる。そのため、空孔率は、約５０％以下であることがより好ましい。また、流路は、空孔率によって限定されるものであり、このような空孔率を有する流路の長手方向に垂直な断面の形状及び流路が形成される位置は、特に限定されるものではない。従って、断面の形状は、円形状、半円形状、楕円形状、三角形状、四角形状、多角形状、及び、星型形状等の様々な形状とすることができる。また、流路を形成する位置は、支持部材の外周内であっても、外周上であってもよく、支持部材の中心に対象的な位置関係にあることが好ましい。しかし、不規則な位置関係であってもよい。 Therefore, if the porosity is about 70% or more, the cross-sectional area of the support part is reduced, making it difficult to support the heated aroma generating substrate and the heated aroma generating source on a surface, and making it difficult to prevent damage and movement of these when the heated aroma cartridge is attached and when smoking. Therefore, it is more preferable that the porosity is about 50% or less. In addition, the flow path is limited by the porosity, and the shape of the cross section perpendicular to the longitudinal direction of the flow path having such a porosity and the position where the flow path is formed are not particularly limited. Therefore, the cross-sectional shape can be various shapes such as a circle, a semicircle, an ellipse, a triangle, a square, a polygon, and a star. In addition, the position where the flow path is formed may be within or on the outer periphery of the support member, and is preferably in a symmetrical positional relationship with the center of the support member. However, an irregular positional relationship is also possible.
一方、加熱式喫煙において重要な要素の一つである煙は、エアロゾルフォーマの揮発物である蒸気が通過する流路となっているマウスピースで生成されるため、マウスピースの構成は、煙の生成に大きな影響を及ぼす。 On the other hand, smoke, which is one of the important elements in heated smoking, is generated in the mouthpiece, which acts as a passageway for the vapor, a volatile component of the aerosol former, so the configuration of the mouthpiece has a significant impact on smoke generation.
マウスピースは、支持部材、冷却部材、及び、フィルターから選択される一つ以上を備えているが、加熱された被加熱芳香発生基材から発生するエアロゾルフォーマの揮発物が通過する流路となる支持部材及び冷却部材が、凝縮という核生成現象による煙を生成する場として重要な役割を果たしている。 The mouthpiece is equipped with one or more selected from a support member, a cooling member, and a filter. The support member and the cooling member, which serve as the flow path through which the volatiles of the aerosol former generated from the heated aroma-generating substrate pass, play an important role as the site for generating smoke through the nucleation phenomenon of condensation.
従来は、支持部材が被加熱芳香発生基材及び被加熱芳香発生源の移動を防止し、比表面積が大きい冷却部材で煙を生成するという考え方で、両者を備えた複雑な構造のマウスピースが設計されてきた。冷却部材は、流路が十分に確保された中空の円筒状であるものが代表例として挙げられる。一方、冷却部材は、揮発物との接触面積が大きくなるように、複雑な凹凸の激しい流路や多数の細い流路の集合体が用いられてきた。 Conventionally, mouthpieces with a complex structure incorporating both a support member to prevent the movement of the heated aroma-generating substrate and the heated aroma-generating source, and a cooling member with a large specific surface area to generate smoke, have been designed. A typical example of a cooling member is a hollow cylinder with a sufficient flow path. However, cooling members have been used that have complex, uneven flow paths or a collection of many thin flow paths to increase the contact area with the volatiles.
そのため、被加熱芳香発生基材及び被加熱芳香発生源を受ける支持部材の支持部の断面積が小さく、揮発物は流れ易いが、被加熱芳香カートリッジの装着時及び喫煙時における被加熱芳香発生基材及び被加熱芳香発生源の破損及び移動等を防止することが困難であった。一方、冷却部材は、揮発物との接触面積が大きく、煙の発生が多いが、セルロースアセテート繊維の束から形成された紙巻きタバコ同様のフィルターや物質吸着能に優れた細孔構造のように、有害物質と共に煙を付着してしまい、煙の生成量が不十分であるという問題があった。また、支持部材と冷却部材を設けるのは、マウスピースの構造を複雑にするという問題もあった。 As a result, the cross-sectional area of the support portion of the support member that receives the heated aroma-generating substrate and the heated aroma-generating source is small, and volatile matter flows easily, but it is difficult to prevent damage and movement of the heated aroma-generating substrate and the heated aroma-generating source when the heated aroma cartridge is attached and when smoking. On the other hand, the cooling member has a large contact area with the volatile matter and generates a lot of smoke, but unlike filters similar to those used in cigarettes made from bundles of cellulose acetate fibers and pore structures with excellent substance adsorption capacity, the smoke adheres to the cooling member along with harmful substances, resulting in insufficient smoke production. In addition, providing a support member and a cooling member also creates the problem of complicating the structure of the mouthpiece.
本発明の支持部材は、流路の空孔率が、約１～７０％、より好ましくは、約１～５０％の範囲にあって、異なる空孔率の流路を二つ以上、より好ましくは、三つ以上備え、流路の最小空孔率と最大空孔率の差が、約１９～６９％、より好ましくは、約１９～４９％である流路を備えていることを特徴としている。このような構造が、被加熱芳香発生基材及び被加熱芳香発生源の破損及び移動の防止に効果的であることは上述した通りであるが、このような構造は、煙の生成にも好ましい。 The support member of the present invention is characterized in that the porosity of the flow path is in the range of about 1-70%, more preferably about 1-50%, and has two or more, more preferably three or more, flow paths with different porosities, and the difference between the minimum and maximum porosities of the flow paths is about 19-69%, more preferably about 19-49%. As mentioned above, such a structure is effective in preventing damage and movement of the heated aroma-generating substrate and the heated aroma-generating source, and is also preferable for smoke generation.
エアロゾルフォーマの揮発物の冷却による煙の生成は、気相中の均質凝縮核生成と壁面状の不均質凝縮核生成の二つの生成が考えられ、壁面状の不均質凝縮核生成による一次核生成に引き続き、気相中の均質凝縮核生成である二次核生成が生じているものと考えられる。ここで、特に、二次核生成の均質凝縮核は、一次核生成の不均質凝縮核よりも小さく、二次核生成数が、一次核生成数よりも多く、芳香カートリッジが生成する煙の量及び大きさと密接に係わっていることが実験的に分かった。そして、この二次核生成数は、冷却速度が増加する程、また、蒸気の流れが乱流である程増加するので、それに伴い、核の平均粒子径が低下するため、芳香カートリッジが生成する煙の量及び大きさに大きな影響を与えることになる。 The generation of smoke by cooling the volatiles in the aerosol former is thought to occur in two ways: homogeneous condensation nucleation in the gas phase and heterogeneous condensation nucleation on the wall. It is believed that secondary nucleation, which is homogeneous condensation nucleation in the gas phase, occurs following primary nucleation by heterogeneous condensation nucleation on the wall. Here, it has been experimentally found that the homogeneous condensation nuclei of secondary nucleation are smaller than the heterogeneous condensation nuclei of primary nucleation, and the number of secondary nuclei is greater than the number of primary nuclei, which is closely related to the amount and size of smoke generated by the aroma cartridge. The number of secondary nuclei increases as the cooling rate increases and the steam flow becomes more turbulent, and as a result, the average particle size of the nuclei decreases, which has a significant impact on the amount and size of smoke generated by the aroma cartridge.
従って、空孔率が小さい流路においては、流路表面とエアロゾルフォーマの揮発物との接触面積が相対的に大きくなり、冷却速度が増加すると共に、冷却部材の流路を流体力学に基づいた、連続の式、ベルヌーイの定理、レイノルズ数から明らかなように、流速が大きくなり乱流を形成しやすいため、平均粒子径の小さな煙が多数生成する。一方、空孔率が大きい流路においては、その逆の現象から、平均粒子径の大きな煙が生成する。このように、空孔率の異なる流路を支持部材に形成することによって、喫煙に好ましい煙が生成されるのである。そして、種々実験を行った結果、流路の最小空孔率と最大空孔率の差は、約１９～６９％であることが好ましく、約１９～４９％であることがより好ましいことが明らかとなった。 Therefore, in a flow path with a low porosity, the contact area between the flow path surface and the volatiles of the aerosol former becomes relatively large, and the cooling rate increases. As is clear from the equation of continuity, Bernoulli's theorem, and Reynolds number, which are based on fluid mechanics, the flow velocity of the cooling member increases and turbulence is easily formed, generating a large amount of smoke with a small average particle size. On the other hand, in a flow path with a high porosity, the opposite phenomenon occurs, generating smoke with a large average particle size. In this way, by forming flow paths with different porosities in the support member, smoke that is suitable for smoking is generated. And, as a result of various experiments, it was revealed that the difference between the minimum and maximum porosity of the flow path is preferably about 19 to 69%, and more preferably about 19 to 49%.
更に、煙の生成と流路の揮発物との接触表面積も重要な要素であり、支持部材の長さ１ｍｍ当たり１８～５００ｍｍ２であることが好ましく、１８～３００ｍｍ２であることがより好ましく、１８～２５０ｍｍ２であることがより更に好ましい。このような観点から、流路の長手方向に垂直な断面の形状は、接触表面積に限定されるもので、特に限定されるものではなく、円形状、半円形状、楕円形状、三角形状、四角形状、多角形状、及び、星型状等の様々な形状とすることができる。また、流路を形成する位置は、支持部材の外周内であっても、外周上であってもよく、支持部材の中心に対象的な位置関係にあることが好ましいが、不規則な位置関係であってもよい。ただし、空孔率を一定にした場合、単位面積当たりの外周の長さが長い程接触面積が増加すること、及び、流路の形成が容易であることから、円形状よりも、四角形状、三角形状の方がより好ましい。また、流路内面に凹凸等を形成することも望ましい。 Furthermore, the contact surface area between the smoke generation and the volatile matter in the flow path is also an important factor, and is preferably 18 to 500 mm2 per mm of the length of the support member, more preferably 18 to 300 mm2 , and even more preferably 18 to 250 mm2. From this viewpoint, the shape of the cross section perpendicular to the longitudinal direction of the flow path is limited to the contact surface area, and is not particularly limited, and can be various shapes such as a circle, a semicircle, an ellipse, a triangle, a square, a polygon, and a star. In addition, the position where the flow path is formed may be within or on the outer periphery of the support member, and is preferably in a symmetrical positional relationship with the center of the support member, but may be an irregular positional relationship. However, when the porosity is constant, the longer the outer periphery length per unit area, the greater the contact area, and the easier it is to form the flow path, so a square shape or a triangular shape is more preferable than a circle. In addition, it is also desirable to form irregularities on the inner surface of the flow path.
このように、本発明の空孔率及び接触面積を有する支持部材は、煙の発生と密接な関係にあると共に、既に述べたように、被加熱芳香発生基材及び被加熱芳香発生源を受ける支持部の面積を損なわないので、本発明の支持部材を用いることによって、支持部材と冷却部材を兼ね備えた、簡単な構造の被加熱芳香カートリッジを提供することができる。 In this way, the support member having the porosity and contact area of the present invention is closely related to the generation of smoke, and as already mentioned, does not impair the area of the support part that receives the heated aroma-generating substrate and the heated aroma-generating source. Therefore, by using the support member of the present invention, it is possible to provide a heated aroma cartridge of simple structure that combines a support member and a cooling member.
一方、一次核生成は、蒸気の壁面との濡れ性が高い程、核生成が生じやすいことも、実験的に確認され、支持部材の材質としては、水酸基、カルボキシル基、アミノ基、アミド基、及び、エーテル基を含有する親水性ポリマーであることが好ましい。このような親水性ポリマーの代表例としては、エチレン－ビニルアルコール共重合体、アクリル酸共重合体、メタクリル酸共重合体、マレイン酸共重合体、アクリルアミド共重合体、４級アンモニウム塩型共重合体、各種ナイロン、各種ポリエーテル等をあげることができる。 On the other hand, it has been experimentally confirmed that primary nucleation occurs more easily when the steam has a higher wettability with the wall surface, and the material of the support member is preferably a hydrophilic polymer containing hydroxyl groups, carboxyl groups, amino groups, amide groups, and ether groups. Representative examples of such hydrophilic polymers include ethylene-vinyl alcohol copolymers, acrylic acid copolymers, methacrylic acid copolymers, maleic acid copolymers, acrylamide copolymers, quaternary ammonium salt type copolymers, various nylons, various polyethers, etc.
このような支持部材によれば、空孔率の異なる流路から生成する平均粒子径の異なる煙を個別に吸引されることになるが、それぞれが混合されて吸引される場合と比較したところ、例えば、支持部材の下流側の端部付近に、二つ以上の流路から流出される揮発物が混合される合流流路を形成した方が、それぞれが個別に吸引されるよりも心地よい喫煙が行えることが分かった。 With such a support member, smoke with different average particle sizes generated from flow paths with different porosity is inhaled separately, but when compared to mixing and inhaling each of the smoke, it was found that a more comfortable smoking experience can be achieved by forming a confluence flow path near the downstream end of the support member where volatiles flowing out from two or more flow paths are mixed, rather than inhaling each of the smoke separately.
また、心地よい喫煙を楽しめる煙に占める小さな平均粒子径の煙と大きな平均粒子径の煙の割合は、平均的には、１対１であることが好ましく、空孔率の小さな流路の総空孔率と空孔率の大きな流路の総空孔率は等しいことが好ましいが、個人差があり、これらの総空孔率の異なる支持部材の被加熱芳香カートリッジを異なる製品とすることができる。 In addition, it is preferable that the ratio of smoke with a small average particle size to smoke with a large average particle size in the smoke that allows for a pleasant smoking experience is, on average, 1:1, and it is preferable that the total porosity of the flow paths with a small porosity is equal to the total porosity of the flow paths with a large porosity; however, there are individual differences, and heated aroma cartridges with support members having different total porosities can be made into different products.
しかし、様々な味わいの煙を楽しむため、様々な支持部材を交換できるように、被加熱芳香発生源と支持部材を配設されるマウスピースとが着脱できるように、例えば、被加熱芳香発生基材の最外装材としてコネクティング部材を用いることが好ましい。そして、このようなコネクティング部材の材質は、特に限定されるものではないが、ネジ等で嵌合され、着脱に耐えうる円筒状のプラスチックであることが好ましい。例えば、ポリオレフィン系樹脂、ポリエステル系樹脂、ナイロン系樹脂、ＥＶＡ系樹脂、アクリル系樹脂等の汎用樹脂が好ましく用いられるが、自然環境保護の観点から、生分解性プラスチックであることがより好ましい。 However, in order to enjoy smoke with a variety of flavors, and to allow various support members to be replaced, and to allow the heated aroma generating source and the mouthpiece to which the support member is attached to be detached, it is preferable to use, for example, a connecting member as the outermost material of the heated aroma generating base material. The material of such a connecting member is not particularly limited, but is preferably a cylindrical plastic that can be fitted with screws or the like and can withstand attachment and detachment. For example, general-purpose resins such as polyolefin resins, polyester resins, nylon resins, EVA resins, and acrylic resins are preferably used, but from the perspective of protecting the natural environment, it is more preferable that the connecting member be a biodegradable plastic.
このように、本発明の支持部材は、従来の支持部材及び冷却部材以上の機能を有すると共に、被加熱芳香カートリッジの構造を簡略化でき、扱いやすく、喫煙を楽しめる被加熱芳香カートリッジを提供することができる。 In this way, the support member of the present invention has functions equal to or superior to those of conventional support members and cooling members, and can simplify the structure of the heated aroma cartridge, providing a heated aroma cartridge that is easy to handle and allows for enjoyable smoking.
本発明の支持部材は、被加熱芳香発生基材及び前記被加熱芳香発生源の破損や移動等を防止する支持部と、揮発物が通過する空孔率の異なる少なくとも二つ以上の流路を備えているので、被加熱芳香発生基材及び被加熱芳香発生源が破損及び移動することなく受け止める面積を有する支持部が形成できる。 The support member of the present invention has a support section that prevents the heated aroma-generating substrate and the heated aroma-generating source from being damaged or moved, and at least two or more flow paths with different porosity through which volatiles pass, so that a support section having an area large enough to receive the heated aroma-generating substrate and the heated aroma-generating source without damage or movement can be formed.
以下、実施形態を用いて本発明をより詳細に説明するが、本発明はこれらに限定されるものではなく、本発明の主旨を逸脱しない範囲内で種々変更して実施することが可能であり、特許請求の範囲に記載した技術思想によってのみ限定されるものである。 The present invention will be described in more detail below using embodiments, but the present invention is not limited to these, and can be implemented with various modifications within the scope of the invention, which is limited only by the technical ideas described in the claims.

The heated aroma-generating substrate and the heated aroma-generating source, which is an assembly of the heated aroma-generating substrate, used in the examples of the present invention were prepared as follows: Dried and ground saffron flowers, konjac, peppermint leaves, and apricot fruit were used as plants that volatilize aroma components, and these were mixed with crosslinked PVP, β-cyclodextrin, microcrystalline cellulose, and CMC-Na that had been dissolved and mixed in a predetermined amount of pure water/ethanol, and then mixed with glycerin and propylene glycol, and further a potassium sorbate/sodium benzoate aqueous solution with konjac powder dispersed therein was added to prepare a heated aroma-generating substrate composition.

この組成物は、３本ロールを用い、シートの厚さが、０．２８±０．０２ｍｍとなるように成形された。そして、このように成形されたシートは、幅１．５±０．１ｍｍとなるように細断された被加熱芳香発生基材３１０とし、所定量の充填率となるように被加熱芳香発生基材ラッピング部材３２０で巻装された。次いで、この巻装された被加熱芳香発生基材３１０は、長さ１１．５～１２．０ｍｍとなるように断裁された後、水分量が１８～２０質量％となるまで乾燥され、被加熱芳香発生源３００が製造された。 This composition was formed using three rolls to a sheet thickness of 0.28±0.02 mm. The sheet thus formed was then cut into pieces to a width of 1.5±0.1 mm to form heated aroma-generating substrate 310, which was then wrapped with heated aroma-generating substrate wrapping member 320 to achieve a predetermined filling rate. Next, this wrapped heated aroma-generating substrate 310 was cut to a length of 11.5-12.0 mm and then dried until the moisture content was 18-20% by mass, producing heated aroma-generating source 300.
一方、本発明の被加熱芳香カートリッジを構成するマウスピース４００は、図３に示すように、上流側から支持部材５１０とセルロースアセテート繊維の束から形成されたフィルター７００がこの順で連接され、マウスピースラッピング部材４１０で巻装され製造された。 On the other hand, the mouthpiece 400 constituting the heated aroma cartridge of the present invention is manufactured by connecting a support member 510 and a filter 700 formed from a bundle of cellulose acetate fibers in this order from the upstream side, and wrapping them with a mouthpiece wrapping member 410, as shown in FIG. 3.
そして、このようにして製造された被加熱芳香発生源３００とマウスピース４００は、図３に示すように、被加熱芳香カートリッジラッピング部材４１０でマウスピース４００と連接され、被加熱芳香カートリッジ２００が製造された。 The heated aroma generating source 300 and mouthpiece 400 manufactured in this manner were then connected to the mouthpiece 400 by the heated aroma cartridge wrapping member 410, as shown in FIG. 3, to manufacture the heated aroma cartridge 200.
このようにして製造された種々の支持部材を配設した被加熱芳香カートリッジ２００は、図1及び３に示すように、ブレード型熱源１３０が本体１１０のチャンバー１２０の底に備えられた加熱式芳香具であるアイコス（登録商標）１００を用いて評価した。 The heated aroma cartridge 200 with the various support members manufactured in this manner was evaluated using IQOS (registered trademark) 100, a heated aroma device in which a blade-type heat source 130 is provided at the bottom of the chamber 120 of the main body 110, as shown in Figures 1 and 3.
本発明の支持部材及びそれを用いた被加熱芳香カートリッジ２００を、従来の技術と比較するため、図１には、被加熱芳香発生源３００を、中空円筒状の支持部材５００、空孔率が７０％以上有する連続気泡の多孔質体で形成される冷却部材６００、及び、セルロースアセテート繊維の束から形成されたフィルター７００が、この順に連接された従来技術のマウスピース４００Ｒと連接された従来技術の被加熱芳香カートリッジ２００Ｒが、加熱式芳香具１００に装着された状態を示している。 In order to compare the support member of the present invention and the heated aroma cartridge 200 using the same with the prior art, Figure 1 shows a heated aroma generating source 300, which is connected in this order to a hollow cylindrical support member 500, a cooling member 600 made of an open-cell porous material with a porosity of 70% or more, and a filter 700 made of a bundle of cellulose acetate fibers, and a prior art heated aroma cartridge 200R connected to the prior art mouthpiece 400R, which is connected to the prior art heated aroma cartridge 200R, attached to a heated aroma device 100.
図1は、被加熱芳香カートリッジ２００Ｒの中心を通るＸＹ面で切断した断面図であるが、図から第一に分かるのは、支持部材５００の支持部５０２の長手方向に垂直なＹＺ面で切断した断面面積が円周部だけしかなく、被加熱芳香カートリッジ２００Ｒを加熱式芳香具１００に装着する際、及び、喫煙時に吸引する際、被加熱芳香発生基材３１０及び被加熱芳香発生源３００が受ける応力が大きく、破損及び移動という問題が発生することである。第二に、被加熱芳香発生基材３１０が加熱されて生成する揮発物が、支持部材５００の流路５０１を通過するが、流路５０１の内壁面積が小さく、揮発物が冷却され凝縮した煙の生成量は極めて少ないため、冷却部材６００が必要となり、被加熱芳香カートリッジ２００Ｒの構造が複雑になることである。 Figure 1 is a cross-sectional view taken along the XY plane passing through the centre of the heated aroma cartridge 200R. The first thing that can be seen from the figure is that the cross-sectional area taken along the YZ plane perpendicular to the longitudinal direction of the support part 502 of the support member 500 only comprises the circumferential part, and when the heated aroma cartridge 200R is attached to the heated aroma device 100 and when inhaling during smoking, the heated aroma generating substrate 310 and the heated aroma generating source 300 are subjected to great stress, resulting in problems such as breakage and movement. Secondly, the heated aroma generating substrate 310 is heated and generated, and the volatiles pass through the flow path 501 of the support member 500. However, because the inner wall area of the flow path 501 is small and the amount of smoke generated by the volatiles being cooled and condensed is extremely small, a cooling member 600 is required, which complicates the structure of the heated aroma cartridge 200R.
本発明の支持部材は、約１～７０％の空孔率の範囲にあり、空孔率の差が約１９％～６９％の異なる少なくとも二つ以上の流路を備えることによって、被加熱芳香発生基材及び被加熱芳香発生源を受け止める面積が大きな支持部５１２～５５２が形成されると共に、支持部材５１０～５５０の流路５１１１～５５１２から平均粒子径の異なる煙が十分に生成し、上記した従来の被加熱芳香カートリッジ２００Ｒの支持部材５００及び冷却部材６００の問題を解決することができた。 The support member of the present invention has a porosity range of approximately 1-70%, and by having at least two or more flow paths with a difference in porosity of approximately 19%-69%, support sections 512-552 are formed with a large area for receiving the heated aroma-generating substrate and the heated aroma-generating source, and smoke with different average particle sizes is sufficiently generated from the flow paths 5111-5512 of the support members 510-550, solving the problems with the support member 500 and cooling member 600 of the conventional heated aroma cartridge 200R described above.
図２は、本発明の一実施形態に係る、空孔率が約６％の円柱状気体流路５１１１と空孔率が約２５％の円柱状気体流路５１１２と、被加熱芳香源支持部５１２を備える第一支持部材５１０の、（ａ）斜視模式図、（ｂ）ＸＹ面で切断した断面模式図、（ｃ）Ｘ軸左方向から見た側面図、（ｄ）Ｘ軸右方向から見た側面図である。 Figure 2 shows (a) a schematic perspective view, (b) a schematic cross-sectional view cut along the XY plane, (c) a side view seen from the left along the X axis, and (d) a side view seen from the right along the X axis of a first support member 510 according to one embodiment of the present invention, the first support member 510 having a cylindrical gas flow path 5111 with a porosity of approximately 6%, a cylindrical gas flow path 5112 with a porosity of approximately 25%, and a heated aroma source support section 512.
図３は、本発明の一実施形態に係る、図２に示す第一支持部材５１０が配設されている被加熱芳香カートリッジ２００を加熱式芳香具１００に装着し喫煙時の状態を示す、被加熱芳香カートリッジの中心を通り、ＸＹ面で切断した断面模式図である。 Figure 3 is a schematic cross-sectional view taken along the XY plane passing through the center of the heated aroma cartridge, showing the heated aroma cartridge 200 having the first support member 510 shown in Figure 2 disposed thereon according to one embodiment of the present invention attached to the heated aroma device 100 during smoking.
このような支持部材５１０を用いることによって、図から明らかなように、被加熱芳香源支持部５１２の断面積が確保され、特に、被加熱芳香カートリッジ２００を加熱式芳香具１００に装着する際の被加熱芳香発生基材３１０及び被加熱芳香発生源３００の破損及び移動を確実に防止することができる。また、空孔率の小さな流路は、流速が大きいため乱流になるので、二次核生成による平均粒子径の小さな煙が大量に生成するのに対し、空孔率の大きな流路からは、平均粒子径の大きな煙が少量生成する。このように、空孔率の異なる二つの流路からは、異なる平均粒子径及び量の煙が生成することによって、心地よい喫煙を楽しめることが分かった。 By using such a support member 510, as is clear from the figure, the cross-sectional area of the heated aroma source support portion 512 is ensured, and in particular, damage and movement of the heated aroma generating substrate 310 and the heated aroma generating source 300 can be reliably prevented when attaching the heated aroma cartridge 200 to the heated aroma device 100. In addition, a flow path with a low porosity has a high flow rate and becomes turbulent, so a large amount of smoke with a small average particle size is generated due to secondary nucleation, whereas a flow path with a high porosity generates a small amount of smoke with a large average particle size. In this way, it was found that the two flow paths with different porosities generate smoke with different average particle sizes and amounts, allowing for a comfortable smoking experience.
図４は、本発明の一実施形態に係る、空孔率が約６％の三角柱状気体流路５２１１と空孔率が約２５％の三角柱状気体流路５２１２と、被加熱芳香源支持部５２２を備える第二支持部材５２０の、（ａ）斜視模式図、（ｂ）ＸＹ面で切断した断面模式図、（ｃ）Ｘ軸左方向から見た側面図、（ｄ）Ｘ軸右方向から見た側面図である。 Figure 4 shows (a) a schematic perspective view, (b) a schematic cross-sectional view cut along the XY plane, (c) a side view seen from the left along the X axis, and (d) a side view seen from the right along the X axis of a second support member 520 according to one embodiment of the present invention, the second support member 520 having a triangular prism-shaped gas flow path 5211 with a porosity of approximately 6%, a triangular prism-shaped gas flow path 5212 with a porosity of approximately 25%, and a heated aroma source support section 522.
図５は、本発明の一実施形態に係る、空孔率が約６％の四角柱状気体流路５３１１と空孔率が約２５％の四角柱状気体流路５３１２と、被加熱芳香源支持部５３２を備える第三支持部材５３０の、（ａ）斜視模式図、（ｂ）ＸＹ面で切断した断面模式図、（ｃ）Ｘ軸左方向から見た側面図、（ｄ）Ｘ軸右方向から見た側面図である。 Figure 5 shows (a) a schematic perspective view, (b) a schematic cross-sectional view cut along the XY plane, (c) a side view seen from the left direction along the X axis, and (d) a side view seen from the right direction along the X axis of a third support member 530 according to one embodiment of the present invention, which is equipped with a rectangular columnar gas flow path 5311 having a porosity of approximately 6%, a rectangular columnar gas flow path 5312 having a porosity of approximately 25%, and a heated aroma source support section 532.
このように、空孔率は全く同じであるが、流路の断面形状が異なることによって、被加熱芳香発生基材３１０及び３００の破損及び移動を防止する効果に変化はないが、断面形状が異なることによって、流路の外周が、円、四角、三角の順に長くなるため、この順で流路の内壁の揮発物との接触面積が大きくなる。それに伴って、冷却速度が大きくなり、特に、二次核生成速度が大きくなり、平均粒子径が小さな煙が大量に生成することになり、喫煙時の吸引する煙の感覚及び味わいに変化が生じる。この感覚及び味わいは、個人差があるため、製品のバリエーションを高める手段として有効である。 Thus, although the porosity is exactly the same, the difference in the cross-sectional shape of the flow path does not affect the effect of preventing damage and movement of the heated aroma-generating substrates 310 and 300. However, due to the difference in the cross-sectional shape, the circumference of the flow path becomes longer in the order of circle, square, and triangle, and the contact area with the volatiles on the inner wall of the flow path increases in this order. As a result, the cooling rate increases, and in particular the secondary nucleation rate increases, resulting in the generation of large amounts of smoke with small average particle diameters, which changes the sensation and taste of the smoke inhaled when smoking. Since this sensation and taste vary from person to person, this is effective as a means of increasing product variety.
図６は、本発明の一実施形態に係る、空孔率が約３％の円柱状気体流路５４１１、空孔率が約９％の円柱状気体流路５４１２、及び、空孔率が約１８％の円柱状気体流路５４１３と、被加熱芳香源支持部５４２を備える第四支持部材５４０の、（ａ）斜視模式図、（ｂ）ＸＹ面で切断した断面模式図、（ｃ）Ｘ軸左方向から見た側面図、（ｄ）Ｘ軸右方向から見た側面図である。 Figure 6 shows (a) a schematic perspective view, (b) a schematic cross-sectional view cut along the XY plane, (c) a side view seen from the left along the X axis, and (d) a side view seen from the right along the X axis of a fourth support member 540 having a cylindrical gas flow path 5411 with a porosity of approximately 3%, a cylindrical gas flow path 5412 with a porosity of approximately 9%, and a cylindrical gas flow path 5413 with a porosity of approximately 18%, and a heated aroma source support section 542, according to one embodiment of the present invention.
この三つの異なる空孔率の総空孔率は約３０％で、第一支持部材５１０、第二支持部材５２０、及び、第三支持部材５３０の総空孔率３１％と大差ないが、揮発物との接触表面積が増加するため、全ての煙の生成量が多くなると共に、全ての煙の平均粒子径分布は更に広がり、喫煙の感覚及び味わいに変化がもたらされ、製品のバリエーションを高めることができる。 The total porosity of these three different porosities is approximately 30%, which is not significantly different from the total porosity of 31% for the first support member 510, the second support member 520, and the third support member 530. However, the increased surface area of contact with volatiles increases the amount of smoke produced overall and further widens the average particle size distribution of all smoke, resulting in changes to the smoking sensation and taste and increasing product variety.
図７は、本発明の一実施形態に係る、空孔率が約６％の円柱状気体流路５５１１及び空孔率が約２５％の円柱状気体流路５５１２、被加熱芳香源支持部５５２、並びに、これら空孔率が異なる二つの円柱状気体流路の円柱状合流流路５５３を備える、第五支持部材５５０の、（ａ）斜視模式図、（ｂ）ＸＹ面で切断した断面模式図、（ｃ）Ｘ軸左方向から見た側面図、（ｄ）Ｘ軸右方向から見た側面図である。 Figure 7 shows (a) a schematic perspective view, (b) a schematic cross-sectional view cut along the XY plane, (c) a side view seen from the left along the X axis, and (d) a side view seen from the right along the X axis of a fifth support member 550 according to one embodiment of the present invention, which is equipped with a cylindrical gas flow path 5511 having a porosity of approximately 6%, a cylindrical gas flow path 5512 having a porosity of approximately 25%, a heated aroma source support section 552, and a cylindrical merging flow path 553 of these two cylindrical gas flow paths with different porosities.
このような合流流路５５３は、支持部材の下流端に形成されるため、被加熱芳香発生基材３１０及び被加熱芳香発生源３００の破損及び移動の防止、並びに、流路からの煙の生成に大きな変化をもたらすことはないが、平均粒子径の異なる煙が混合されて口腔内に吸引されるため、合流流路５５３のない場合とは異なった煙の感覚及び味わいとなることが分かった。 Since such a confluence flow path 553 is formed at the downstream end of the support member, it prevents damage and movement of the heated aroma-generating substrate 310 and the heated aroma-generating source 300, and does not significantly change the smoke generated from the flow paths. However, it has been found that smoke with different average particle sizes is mixed and inhaled into the oral cavity, resulting in a different sensation and taste of the smoke than when the confluence flow path 553 is not present.
以上のように、本発明の支持部材は、被加熱芳香カートリッジの装着時及び喫煙時の被加熱芳香発生基材３１０及び３００の破損及び移動を防止できるだけでなく、空孔率の大きさ、流路の形状、流路の数、合流流路の形成等を制御することによって、同じ被加熱芳香発生基材から生成するエアロゾルフォーマ揮発物の冷却、凝縮により生成する煙の平均粒子径や量が異なり、異なった喫煙の感覚及び味わいを堪能することができる。 As described above, the support member of the present invention not only prevents damage and movement of the heated aroma generating substrates 310 and 300 when the heated aroma cartridge is attached and when smoking, but also varies the average particle size and amount of smoke generated by cooling and condensing the aerosol former volatiles generated from the same heated aroma generating substrate by controlling the porosity, shape of the flow paths, number of flow paths, formation of merging flow paths, etc., allowing different smoking sensations and flavors to be enjoyed.
そこで、このような本発明の支持部材の特徴を積極的に活用するため、図8に示すような着脱可能な被加熱芳香カートリッジコネクティング部材２２０を使用することによって、同一の被加熱芳香発生基材の被加熱芳香カートリッジを様々な感覚及び味わいで喫煙を堪能することができる。 In order to make the most of the features of the support member of the present invention, a detachable heated aroma cartridge connecting member 220 as shown in Figure 8 is used, allowing users to enjoy smoking with a variety of sensations and flavors using heated aroma cartridges made of the same heated aroma generating substrate.
