Abstract
【解決手段】プリフォームの胴部に連なる底部をすり鉢状に形成する。底部は胴部よりも肉厚が薄肉で平坦な底面中央部と、ボトル底縁となる部分の高さ位置から胴下部を底面中央部の周囲まで屈曲して傾斜形成したボトル底面形成部と、そのボトル底面形成部の胴部と接する上部のボトル底縁形成部位と、ボトル底面形成部の下部と底面中央部との境の弯曲部とからなる。ボトル底面形成部の肉厚を、ボトル底縁形成部位を除く弯曲部までの内面の肉盛により、胴部の肉厚よりも厚肉に形成する。ボトル底縁形成部位の肉厚をボトル底面形成部の肉厚よりも薄肉に形成する。

上記比較例との対比から、この発明のプリフォームにより延伸ブロー成形されたボトルの方が、従来のプリフォームにより延伸ブロー成形されたボトルよりもボトル底面の肉厚が薄く形成され、ボトル底面の質量も減少している。この減少分はボトル胴部側に分配されて胴部肉厚の増加となる。よって、その減少量を減じた質量のプリフォームにより同様なボトルを延伸ブロー成形することが可能となる。これによりボトルの軽量化を図ることができる。
