Description
ポリエチレンで作られた円形メッシュ(直径6.6cm、メッシュフィラメントの直径2mm、方形メッシュにおけるメッシュフィラメント間の隔離距離:10mm)と、発泡ポリエチレン(PE)(厚さ:3mm、密度:194kg/m3、直径:6.6cm)及び厚さ0.5mm(直径:6.6cm)のポリテトラフルオロエチレン層(PTFE)で作られた複合体とを、ねじ山付きの直径6.6cmの市販のポリエチレンクロージャキャップに挿入した。キャップはさらに、開封前の損傷の存在を示す安全リングを有していた。
ポリエチレンで作られた円形メッシュ(直径6.6cm、メッシュフィラメントの直径2mm、方形メッシュにおけるメッシュフィラメント間の隔離距離:10mm)と、発泡ポリエチレン(PE)(厚さ:3mm、密度:194kg/m3、直径:6.6cm)及び厚さ0.5mm(直径:6.6cm)のポリテトラフルオロエチレン層(PTFE)で作られた複合体とを、ねじ山付きの直径6.6cmの市販のポリエチレンクロージャキャップに挿入した。キャップはさらに、開封前の損傷の存在を示す安全リングを有していた。
6リットルの容量のアルミニウム製ボトルをねじ山付きの市販のキャップで6.7Nmのトルクで閉鎖した。圧縮された空気を使用して1.5バールの圧力を生成し、発生し得る圧力の低下を3日間にわたって観察した。ボトル内の圧力をボトルに一体化されたマノメータによって測定した。圧力の解放は測定されなかった。
実施例1の発泡ポリエチレン(PE)(6)及びポリテトラフルオロエチレン層(PTFE)(7)を含む複合体が挿入されるが追加メッシュ(4)を含まないキャップを使用して、3リットルのジメチルジカルボネート及び1リットルの水を含有する30リットルのガラスボトルを6.7Nmのトルクで閉鎖した。圧力増大の24時間後、ガラスは10バールの圧力で砕け散った。
