Abstract
Description
実施形態1:エアロゾル送達装置であって、ハウジングと、再生セルロース繊維から少なくとも部分的に形成された基材と、基材によって保持されるエアロゾル形成液体と、エアロゾル形成液体の気化のために動作可能に配置されたヒータとを備え、再生セルロース繊維が、中空の略円筒形の断面を有する再生セルロース繊維、多葉断面を有する再生セルロース繊維、疎水性添加剤を含む再生セルロース繊維のうちの1つ以上を含む、エアロゾル送達装置。
基材の吸収性を評価するために、複数の基材を単層基材または多層基材として作成した。サンプルの形成には、以下の3種類の異なる繊維が使用された:略円形または楕円形の断面を有するBRAMANTE中空セグメント化繊維(3.3dtex×40mm)(以下「B」と表記);条痕を有するGALAXY(R)三葉繊維(3.3dtex×30mm)(以下「G」と表記);および繊維形成材料に共有結合的に架橋された長鎖炭化水素を有するOLEA疎水性繊維(1.7dtex×30mm)(以下「O」と表記)。3種類の繊維は全て、再生セルロースから形成される。単層基材は、3種類の繊維のステープル繊維から形成され、各基材は、単一種類の繊維、すなわち、100重量%B繊維、100重量%G繊維、または100重量%O繊維のみから形成された。対照および比較サンプルを、プレーン酢酸セルロースを使用して作成した。全ての基材は、乾式プロセスを使用して形成された。全ての単層サンプルについて、各サンプルあたり80グラムの繊維を秤量した。繊維をカードに3回通して、完成したウェブの許容可能な開口および均一性を確保した。2層のサンプルでは、40グラムの繊維を使用して各層のウェブを作製した。繊維は、均一性および分散のために、カードに再度3回通された。そして、これらの層は、ニードリングのために互いに積み重ねられ、または接着剤による接着のために接着ウェブによって層状にされた。3層のサンプルでは、26.5グラムの各繊維が重量測定され、1層および2層のサンプルと同じ手順にしたがった。ニードルリングは、フェルト織機実験室ニードラーで行った。各サンプルをニードラーに4回通した(各側で2回)。ニードル織機の速度とインチあたりのパンチ(ppi)は、両方とも50%に設定された。使用したニードルは、ニードルごとに6本のバーブであった。「接着された」サンプルは、軽量ポリエチレン接着ウェブ(例えば、Bostik PO104ホットメルトウェブ接着剤)によって接着された。サンプルを接着ウェブと層状にし、240°Fで30秒間ホットプレスにかけた。基材サンプルは、プレーン酢酸セルロース基材、ニードル処理されたプレーン酢酸セルロース基材、および有機綿基材に対して試験された。本開示による基材の15個の発明サンプルが評価され、各基材の組成は、対照および比較サンプルの組成とともに以下の表1に示される。
エアロゾル形成のためにエアロゾル前駆体組成物を放出する基材の能力が、試験装置において例1からのサンプルのそれぞれを使用することにより評価された。試験は、図1に示すカートリッジ104と同様の構造のカートリッジを使用して実施された。各試験サンプルは、均一な寸法で提供され、図1に示されるリザーバ144として使用された。パフシミュレーションは、市販のパフシミュレーション装置、すなわち、タバコ喫煙機を利用して実施された。パフシミュレーションは、パフ間の時間間隔を30秒として3秒間のパフ(55cm3の容積)で実施された。パフグループの中間点が平均として使用された。パフ0で質量測定を行った後、各リザーバ基材材料について20回の単独のパフを収集し、パフは、タバコ煙に含まれる総粒子状物質(TPM)の収集に一般的に使用されるケンブリッジフィルタパッドで収集された。生成された総質量を20で除算して、パフあたりの質量を求めた。プロットの目的で、パフグループの中間点におけるパフあたりの平均質量(すなわち、パフ10における質量)を使用した。
