Abstract
【選択図】図1
Description
別の実施形態によれば、喫煙物品は、タバコロッドとフィルタを含み、フィルタは、先端紙を用いてタバコロッドに取り付けられてチューブの下流端で開いた紙フィルタチューブと、フィルタチューブ内に収容されてフィルタチューブを上流空洞及び下流空洞に分割する流量制限器と、先端紙及びフィルタチューブを通って延びる複数の穿孔を含む、下流空洞に沿った位置の通気区画とを含む。
図4は、別の実施形態による流量制限器30の断面図を示している。図4に示すように、流量制限器30の圧力降下が開口面積に依存するので、複数のオリフィス34を使用することもできる。例えば、更に別の実施形態によれば、直径38が少なくとも0.2mmの少なくとも2つ又はそれよりも多くのオリフィス34をそれぞれ仕切り32に取り入れることができる。仕切り32内でオリフィス34の数、サイズ、及び配置又は位置は、通気区画40と組み合わせて、フィルタ14内で望ましい圧力降下を設定することができるように変えることができることを認めることができる。
図7は、別の実施形態による流量制限器30の断面図を示している。図7に示すように、流量制限器30は、紙発泡体ロッド66の外周部67の周りにV字形断面を有する複数の溝65の形態をした複数のチャンネル60を含む。溝65がV字形、矩形、楕円形、又は他の適切な構成にすることができることを認めることができる。
図9は、流量制限器30の別の代替的な実施形態の側面断面図を示している。流量制限器30は、少なくとも1つのオリフィス34と仕切り32の外周部33周りに延びる外側環46とを有する仕切り32を含む。図9に示すように、外側環46は、面取りした又は傾斜端部50を有する対称の基礎48を含み、流量制限器30の管状セグメント18への挿入を容易にすることができる。
本明細書に示して説明した実施形態は、望ましい量の吸引抵抗と共に高度に通気した喫煙物品の恩典を提供し、従来型のシガレット製造機械上での高速度シガレット製造を容易にする。
