Description
突起3は、突起3の頂点と他のプリフォーム2の内面が接触すると、底部12と口部4の内面との間に若干の間隙を形成する高さを有している。また突起3は、ストレート部7の延長面より外方には突出しない高さである。
これは、突起3に代えて、底部12の中心から放射状に沿って突条5を設けた例である。このように突条5を形成しても、プリフォーム2が他のプリフォーム2内に進入した場合に、プリフォーム2どうしの固着を防止し、抜けなくなることを防ぐことができる。
尚、Rは底部12の曲率半径、αはプリフォーム2の口部4の内面角度である。

Claims (3)
- 樹脂製容器を形成するためのプリフォームであり、
該プリフォームは、口部と該口部に連続した有底の円筒状胴部を具え、
該胴部は、底部から所定の位置まで、前記口部の内径より細い外径であり、前記底部に、該プリフォームと同形の他のプリフォームの口部内部に前記胴部が進入した際、該他のプリフォームの内面奥部に接する突起を具えたことを特徴とするブロッキング防止プリフォーム。 - 突起は、底部の湾曲中心を中心に、該底部の最下点から上方に角度β(β=90−α)の位置に形成した(αは、口部内部の鉛直に対する傾斜角度)請求項1に記載のブロッキング防止プリフォーム。
- 口部は、該口部外周にキャップが螺合する雄ねじ部と、該雄ねじ部の下部に外方向に突出したネックリングを具え、胴部は、該ネックリングの下部から縮径して、前記口部内径より細く形成した請求項1または2に記載のブロッキング防止プリフォーム。
