Description
しばしば、プラスチック容器は、−多層容器の場合少なくとも外層は−着色されている。例えば青色の栓付き樽、又は、電気的にアースされている外層を備えた導電性カーボンブラックで着色された黒のプラスチック容器等である。
全ての公知の多層構成は、内層の無色のプラスチック材料から成る一貫した表示用ストリップを有している。表示用ストリップのこのような製造は、装置的にも方法的にも極めて手間がかかる。即ち、表示用ストリップと容量スケールとを対応して配置させる際に、内部容器の表示用ストリップの周囲位置を、容量スケールの周囲位置に正確に適合させなければならない。内部容器に表示用ストリップを正確に鉛直方向に配置するのも、内部容器の製造の際にブロー成形時の延伸率が異なることにより、行うのは困難である。
プリフォームのホース状壁の内側で、内側から外側へと材料が変向されることに基づき、最終的にブロー成形された製品の壁の内側にも、一貫した分離線(鉛直方向に延びる、容器壁内部の分離線)が生じず、従って、完成された容器の(例えば落下テスト、液圧的な内圧テスト等のような)性能データに不都合な影響は生じない。ホース若しくは完成された容器の内側表面は無傷に維持され、分割されていない。挿入された中空管及び駆動される螺旋状スクリュを有した本発明による押出ヘッドによれば、約60〜1000リットルの種々様々な容積サイズを有する容器、例えば、キャニスタ、樽、又は、パレットコンテナのための大容量のプラスチック内部容器を製造することができる。付加的な押出機又は(逐次運転形式のための)付加的な材料貯え器は不要である。
