細長い喫煙用物品。
本発明は、本発明を例示するために記載されている、以下の実施例によって一層完全に例示され、これを限定するものとして解釈されるべきではない。各実施例において、各燃料素子の着火性は、図1において記載されている一般的な規格の喫煙用物品に燃料素子を配置することにより、およびホルダー中に喫煙用物品を置くことにより決定される。これ以降、燃料素子は、設定時間(例えば、0.5秒、1.0秒など)、火炎に晒され、次に、喫煙用物品に約55mlの体積の一吹きが行われる。次に、燃料素子は、火炎から取り出され、15秒間を経過させる。これ以降、同じ体積の第2の一吹きが行われる。燃料素子が、第2の一吹きの間にオレンジ色/赤色に燃える場合、それは着火していると見なされる。同じ一般的な実験を繰り返し、各実験は、燃料素子が、第2の一吹きの時に着火したと見なされるまで、火炎への曝露の設定時間を徐々に長くして使用する。燃料素子が第2の一吹きの時に着火し続けている最低の設定時間を、着火可能時間として記録する。したがって、例えば、特定の燃料素子が、上記の試験に従って、0.5秒間、火炎に晒され、第2の一吹きの間、オレンジ色または赤色に燃えないが、1.0秒の火炎への曝露時間において、再試験した場合にオレンジ色または赤色に燃えた場合、この着火可能時間は、1.0秒と見なされる。
ミル粉砕炭素、結合剤としてグアーガム、炭酸カルシウムおよびグラファイトを含むいくつかの燃料素子組成物を形成し、非燃焼加熱式シガレットをこれらと共に構成する。各燃料素子組成物に着火するために必要な時間を測定し、市販のECLIPSE製品(これは、燃料素子中に外側の溝を5つ有する。)および燃料素子に外側の溝を8つ有する別の対照となる燃料素子と比較する。試験した組成物は、0.05重量%、0.075重量%および0.1重量%のマイクロスフェア含有レベルを含めた、様々な量のセラミックマイクロスフィア(3Mから入手可能なW−610マイクロスフィア)を含む(この場合、ミル粉砕炭素の量は、セラミックマイクロスフィアを収容するよう減量される。)。実験組成物の一部は、外側の溝を5つまたは8つのどちらかを有する、燃料素子に作製され、一例において、8つの溝およびこれを介して中心孔の両方を有する。
実施例1と同様に、ミル粉砕炭素、結合剤としてグアーガム、炭酸カルシウムおよびグラファイトを含むいくつかの燃料素子組成物を形成し、非燃焼加熱式シガレットをこれと共に構成する。各燃料素子組成物を着火するのに必要な時間を測定し、市販のECLIPSE製品と比較する。試験した組成物は、以下を含む:(A)ミル粉砕炭素、グアーガム、炭酸カルシウム、グラファイト;(B)ミル粉砕炭素、グアーガム、炭酸カルシウム、グラファイト、および5重量%の含浸炭素(Calgon Corporationから入手可能なST1−X含浸炭素)であり、ミル粉砕炭素含有量が、(A)と比べて5%減量されている;(C)10重量%の含浸炭素を有することを除いて、(B)の組成物であり、ミル粉砕炭素含有量は、(A)と比べて、10%減量した;(D)15重量%の含浸炭素を有することを除いて、(C)の組成物であり、ミル粉砕炭素含有量は、(A)と比べて、15%減量した;(E)ミル粉砕炭素、グアーガム、炭酸カルシウム、グラファイト、および5重量%のセルロース粒子(Sigma−Aldrichから入手可能なSigmacellセルロース)であり、他のすべての成分は、(A)と比べて、実質的に比例して減量した;(F)ミル粉砕炭素、グアーガム、炭酸カルシウム、グラファイト、10重量%のST1−X活性炭および5重量%のSigmacellセルロースであり、他の成分はすべて減量したが、ミル粉砕炭素は、(A)と比べて、最も減量した;および(G)3重量%の含浸炭素を有することを除いて、(B)の組成物であり、グラファイト含有量は、(A)と比べて、3%減量した。
ミル粉砕炭素、結合剤としてグアーガム、炭酸カルシウムおよびグラファイトを含むいくつかの燃料素子組成物を形成し、非燃焼加熱式シガレットをこれと共に構成する。各燃料素子組成物に着火するために必要な時間を測定し、市販のECLIPSE製品(これは、燃料素子中に外側の溝を5つ有する。)および燃料素子に外側の溝を8つ有する別の対照の燃料素子と比較する。
