Abstract
Description
実施例1~5によるシガレットに対して霧化量を評価する実験を行った。具体的には、シガレットのフィルターセグメントに投入された紙物質が霧化量にある程度の影響を及ぼすかを評価するために、喫煙後に紙物質の重さ増加量(すなわち、液状カートリッジに発生したエアロゾルなどを吸湿することによって増加した重さ)を測定し、煙成分を分析する実験を行った。また、喫煙時に実際に肉眼で見える霧化量の程度(すなわち、可視霧化量)を相対的に評価した。温度が略20℃であり、湿度が略62.5%である喫煙室で液状カートリッジが装着されたハイブリッド型エアロゾル発生装置(図2または図3参照)を用いて実験を行い、成分分析のための煙捕集は、試料別3回ずつ、回別8パフを基準として反復実施され、3回ずつの捕集結果に対する平均値が下記の表3に記載されている。また、表3に記載されたフィルターセグメントの重さ増加量も、3回ずつの測定結果に対する平均値として算出された。
フィルターセグメント(e.g.211、213)に投入された紙物質の耐油度が霧化量に及ぼす影響を確認するために、有煙モードで実施例6および7によるシガレットの煙成分を分析して、TPM(Total Particulate Matter)含有量を測定する実験を行った。実験方式は、実験例1と同一の方式で行われ、実験結果は、下記の表4に記載されている。
タバコ顆粒のサイズがキャビティセグメント(e.g.212)内部の渦流の発生に及ぼす影響を確認するために、実施例6および8によるシガレットに対する喫煙実験を行い、喫煙後にタバコ顆粒が凝集している程度を確認する実験を行った。キャビティセグメント(e.g.212)内部で渦流がよく発生しうるほどタバコ顆粒が均一に混ざって凝集現象が減少するので、喫煙後にタバコ顆粒の凝集程度が渦流の発生程度を示す尺度になり得るためである。実験結果は、図14および図15に示されており、図14および図15は、喫煙後にタバコ顆粒が凝集している程度を撮影したものであり、それぞれ実施例6(約30メッシュ~45メッシュ)と実施例8(約20メッシュ~30メッシュ)に対する実験結果を示す。
タバコ顆粒の充填率がキャビティセグメント(e.g.212)内部の渦流の発生に及ぼす影響を確認するために、実施例6、9および10によるシガレットに対する喫煙実験を行い、喫煙後にタバコ顆粒が凝集している程度を確認する実験を行った。実験結果は、図16~図18に示されている。図16、図17および図18は、喫煙後にタバコ顆粒が凝集している程度を撮影したものであり、それぞれ実施例9(充填率約50体積%)、実施例6(充填率約75体積%)および実施例10(充填率約100体積%)に対する実験結果を示す。
フィルターセグメントの損傷度が大きいほどタバコ顆粒の脱落現象が加速化できるので、内部加熱要素(e.g.132)の厚さおよび形状がフィルターセグメント(e.g.213)の損傷度に及ぼす影響を確認する実験を行った。具体的には、内部加熱要素の厚さおよび形状を変更しながら、実施例6によるシガレットのフィルターセグメント損傷度を確認する実験を行った。実験結果は、図19~図21に示されている。図19~図21は、内部加熱要素により貫通したフィルターセグメント(e.g.213)の断面を撮影したものであり、それぞれ厚さ約2mmの半円錐型加熱要素、厚さ約2mmの円柱型(棒状)加熱要素および約3mm厚さの円柱型加熱要素に対する実験結果を示す。
