Description
本発明に係るブロー成形型の一実施形態として、その概略を図1に示す。
図1に示すブロー成形型1は、有底筒状のプリフォームPを二軸延伸ブロー成形によって、所定の容器形状に成形するためのものであり、開閉可能に構成された一対の分割型からなる側部型2と、側部型2の底部側に組み入れられる底部型3とを備えている。このようなブロー成形型1は、通常、ステンレス鋼、アルミニウム合金などを用い形成される。
これによって、底部中央型31を冷却しつつ、底部周縁型32を加熱することで、底部中央型31と底部周縁型32のそれぞれを所定の温度に調整し、底部型3の温度分布を好適に制御することを可能にしている。
本発明に係る合成樹脂製容器の製造方法は、上記したようなブロー成形型1を用いて実施することができ、その一実施形態について説明する。
X=(ρc(ρ−ρa))/(ρ(ρc−ρa))
ρa:非晶密度(g/cm3)
ρc:結晶密度(g/cm3)
なお、材料樹脂としてポリエチレンテレフタレートを使用した場合には、ρc=1.455(g/cm3)、ρa=1.335(g/cm3)として、結晶化度X[%]を算出することができる。
