Description

非燃焼加熱型香味吸引物品用フィルタNon-combustion heating type filter for flavor sucking articles
　本発明は、非燃焼加熱型香味吸引物品用フィルタに関する。 The present invention relates to a non-combustion heating type filter for flavor inhalation articles.
　近年、燃焼しないタイプの香味吸引物品が開発されている。当該物品においては、エアロゾル発生基材を加熱してエアロゾルを発生させる。当該物品についても、従来の燃焼型喫煙物品と同様に香喫味の改善が望まれている。従来の燃焼型喫煙物品においては、好ましくない香喫味を与える成分を除去するためにアセテートフィルタ内に活性炭を充填することが知られている。特許文献１には、喫煙材ロッドと少なくとも１つの希釈剤を含む第１シートとを含む喫煙品が開示されている。当該シートは活性炭を含んでいてもよいとされる。また特許文献２には、活性炭含有紙の表面に活性炭を外添し、さらにこの紙を折り込んでラッパー内に充填してなるチャコールフィルターが開示されている。 In recent years, non-burning type flavor inhaling articles have been developed. In such articles, the aerosol-generating substrate is heated to generate an aerosol. Improvements in the flavor and taste of these articles are also desired, as with conventional combustion-type smoking articles. In conventional combustion-type smoking articles, it is known to fill the acetate filter with activated carbon in order to remove components that impart undesirable flavor and taste. US Pat. No. 6,200,000 discloses a smoking article comprising a rod of smoking material and a first sheet comprising at least one diluent. It is said that the sheet may contain activated carbon. Further, Patent Document 2 discloses a charcoal filter in which activated carbon is externally added to the surface of activated carbon-containing paper, and the paper is folded and filled in a wrapper.

　前記特許文献は具体的に燃焼型喫煙物品を開示するが、非燃焼加熱型香味吸引物品への言及はない。発明者らは、前記特許文献に記載されたフィルタをそのまま非燃焼加熱型香味吸引物品に適用すると、十分なろ過特性を発現できないことを見出した。かかる事情に鑑み、本発明は、非燃焼加熱型香味吸引物品において、香喫味に好ましくない影響を与える成分を効率的に除去できるフィルタを提供することを課題とする。 Although the above patent documents specifically disclose combustion smoking articles, there is no reference to non-combustion heating flavor inhalation articles. The inventors have found that if the filter described in the above patent document is applied as it is to a non-combustion heating type flavor inhaling article, sufficient filtration characteristics cannot be exhibited. In view of such circumstances, it is an object of the present invention to provide a filter that can efficiently remove components that adversely affect the flavor and taste of a non-combustion-heating flavor inhalation article.

１．非燃焼加熱型香味吸引物品用フィルタ
　非燃焼加熱型香味吸引物品用フィルタ（以下単に「フィルタ」ともいう）は、筒状のラッパーと、この中に充填されている吸着剤含有シートとを備える。ラッパーは通常、当該分野で使用されているものを使用できる。この中に充填されている吸着剤含有シートは、折り畳まれ、この折り畳みによって形成された稜線が長手方向に略平行となるように充填されていることが好ましい。 1. Filter for Non-Combustion Heating Flavor Inhalation Articles A non-combustion heating filter for flavor inhalation articles (hereinafter also simply referred to as "filter") comprises a cylindrical wrapper and an adsorbent-containing sheet filled therein. A wrapper commonly used in the art can be used. The adsorbent-containing sheet packed therein is preferably folded and filled so that the ridgeline formed by the folding is substantially parallel to the longitudinal direction.
　吸着剤の量（Ｃｈ）を増やすとカルボニル成分等の香喫味に好ましくない影響を与える成分を除去しやすい。一方で吸着剤の量（Ｃｈ）を増やすと通気抵抗（ＰＤ）が上昇し、香喫味に好ましい影響を与える成分が除去される傾向にある。そこで、発明者らはこれらのバランスを標準化するため、Ｃｈ／ＰＤという指標を設定した。かかる観点から、フィルタの通気抵抗あたりの吸着剤量（Ｃｈ／ＰＤ）は、５～１５（ｍｇ／ｍｍＨ2Ｏ）である。Ｃｈ／ＰＤが下限値未満であると、香喫味に好ましくない影響を与える成分の除去が十分でなくなり、さらには必要な成分まで除去されるため香喫味が低下する。一方、Ｃｈ／ＰＤが上記上限値を超えても、香喫味に好ましくない成分の低減能力は飽和する。以上から、Ｃｈ／ＰＤの下限値は、好ましくは６（ｍｇ／ｍｍＨ2Ｏ）以上であり、その上限値は、好ましくは１０（ｍｇ／ｍｍＨ2Ｏ）以下、より好ましくは８（ｍｇ／ｍｍＨ2Ｏ）以下である。 Increasing the amount of adsorbent (Ch) makes it easier to remove components that adversely affect flavor and taste, such as carbonyl components. On the other hand, increasing the amount of adsorbent (Ch) increases airflow resistance (PD) and tends to remove components that have a favorable effect on flavor and taste. Therefore, the inventors set an index of Ch/PD in order to standardize these balances. From this point of view, the amount of adsorbent per ventilation resistance (Ch/PD) of the filter is 5 to 15 (mg/mmH 2 O). If the Ch/PD is less than the lower limit, the removal of components that adversely affect the flavor and taste is insufficient, and even the necessary components are removed, resulting in a decrease in the flavor and taste. On the other hand, even if Ch/PD exceeds the above upper limit, the ability to reduce components that are undesirable for flavor and taste is saturated.

Effective surface area is the total area of adsorbent exposed on the surface of the sheet. This numerical range is based on:
　一態様において、吸着剤のシート内に埋没している面積は、平均すると、吸着剤１つの表面積の３０％～５０％と考えられる。すなわち、吸着剤の露出している面積は、平均して５０％～７０％である。吸着剤の表面積を１０００ｍ2／ｇ、シート中の吸着剤の含有量を１０ｇ／ｍ2とすると、平均して５０％の面積が露出している場合の有効表面積は以下のように算出される。
　１０ｇ／ｍ2×１０００ｍ2／ｇ×５０％＝５０００ｍ2／ｍ2
　吸着剤の表面積を２０００ｍ2／ｇ、前記含有量を５０ｇ／ｍ2とすると、平均して７０％の面積が露出している場合の有効表面積は以下のように算出される。
　５０ｇ／ｍ2×２０００ｍ2／ｇ×７０％＝７０，０００ｍ2／ｍ2 In one aspect, the area buried within the sheet of adsorbent is believed to be, on average, 30% to 50% of the surface area of a single adsorbent. That is, the exposed area of the adsorbent is 50% to 70% on average. Assuming that the surface area of the adsorbent is 1000 m 2 /g and the content of the adsorbent in the sheet is 10 g/m 2 , the effective surface area when an average of 50% of the area is exposed is calculated as follows. .
10g/ m2 x 1000m2 /g x 50% = 5000m2 / m2
Assuming that the surface area of the adsorbent is 2000 m 2 /g and the content is 50 g/m 2 , the effective surface area when 70% of the area is exposed on average is calculated as follows.
50g/ m2 x 2000m2 /g x 70% = 70,000m2 / m2

Crepe treatment is a treatment in which crepe-like creases are formed on a sheet by using a doctor on a roll or the like. The crepe depth is preferably 0.1-0.5 μm.
（７）フィルタの特性
　本実施態様にかかるフィルタは、香喫味に好ましくない影響を与える成分を効率的に除去するが、香喫味に重要である成分は除去しにくいという性能を備える。特に、従来のフィルタでは除去が困難であったホルムアルデヒド、アセトアルデヒド、およびアクロレインを効率よく除去できる。この理由は限定されないが、フィルタ内に適度な大きさの空隙が形成されるとともに、吸着剤がシートのマトリックスにしっかり保持されているためと推察される。また、当該フィルタは蔵置中に水分を吸着することができるので、使用者が吸引物品の初期パフにおいて熱いと感じることを回避できるという効果も奏する。 (7) Filter Characteristics The filter according to the present embodiment has the performance of efficiently removing components that adversely affect the flavor and taste, but it is difficult to remove components that are important to the flavor and taste. In particular, formaldehyde, acetaldehyde, and acrolein, which have been difficult to remove with conventional filters, can be efficiently removed. Although the reason for this is not limited, it is presumed that air gaps of a suitable size are formed in the filter and the adsorbent is firmly held in the matrix of the sheet. The filter can also absorb moisture during storage, thus avoiding the user feeling hot at the initial puff of the suction article.

Furthermore, a predetermined amount of the filtrate was added to the Trizma base solution and shaken to terminate the derivatization reaction. After the solution was filtered through a membrane filter again, it was subjected to HPLC-DAD to analyze the carbonyl component. The method for analyzing the carbonyl component was disclosed in WO2004/026054 and CORESTA Recommended Method No. 96-Determination of Formaldehyde and Acetaldehyde in E-Vapour Product Aerosol February 2021. Table 2 shows the results. Also, FIG. 3 shows the relationship between Ch/PD and the amount of formaldehyde.

　センターホールフィルタとペーパーフィルタを準備した。当該フィルタの物性を表１に示した。第２フィルタ５２の代わりに、当該センターホールフィルタとペーパーフィルタをそれぞれ用いた以外は、実施例と同じ方法で非燃焼加熱型香味吸引物品を調製し、たばこ煙中粒状物質を定量した。結果を表２に示した。 [Comparative Examples 1 and 2]
A center hole filter and a paper filter were prepared. Table 1 shows the physical properties of the filter. Except for using the center hole filter and the paper filter instead of the second filter 52, a non-combustion heating type flavor inhalation article was prepared in the same manner as in the example, and particulate matter in tobacco smoke was quantified. Table 2 shows the results.
　実施例で製造したフィルタは、香喫味に好ましくない影響を与える成分、特に従来のフィルタでは除去が困難であったホルムアルデヒド、アセトアルデヒド、およびアクロレインの除去に有効であることが明らかである。 It is clear that the filters produced in Examples are effective in removing components that adversely affect the flavor and taste, especially formaldehyde, acetaldehyde, and acrolein, which were difficult to remove with conventional filters.
