Abstract
Description
−プリフォームをプラスチックのガラス転移温度よりも高い温度で加熱するステップと、
−このような加熱プリフォームを、金型底部及び側壁が配設された金型の内部に導入するステップであって、側壁が所定温度に加熱される、導入するステップと、
−プリフォームをブロー成形して容器を形成することにより、それに続いて高温内容物を充填するステップと、を含み、
−前記プリフォームの壁は、略円筒形の主セグメントと、底部に隣接する厚さが大きい下側セグメントと、を有することにより、前記下側セグメントが延伸して容器の高さのある自立用リングを形成し、底部が下側セグメントよりも薄い厚さを有することにより、底部が延伸すると、容器の反転可能なダイアフラムを形成するよう延伸し、
−プリフォームに、3.4〜3.9の長さ方向延伸倍率、及び3.5〜3.9のフープ方向延伸倍率が付与される。
−延伸倍率は3.6〜3.8である;
−フープ方向延伸倍率は3.7〜3.8である;
−プリフォームの下側セグメントは、主セグメントの壁厚よりも約10%大きい壁厚を有する;
