Claims (5)
- 試験管状の有底筒状体を熱可塑性樹脂で成形し、筒状体の開口部を掴み、筒状体を宙吊りにして開口部以外の部分を加熱して溶融し、これを吹込成形型に入れ、少なくとも2個の溶融された筒状体が1つの型窩内で宙吊りにされて互いに近接して並んだ状態にし、各筒状体の間に溶着面の位置決め板を挿入するとともに、各筒状体の開口からそれぞれ気体を圧入して各筒状体を容器状に膨らませ、膨らんだ胴部同士が互いに接触しようとする直前に、上記位置決め板を移動させて吹込成形型の型窩内から除き、その後も各筒状体内に気体を圧入し、隣接する容器の向き合った胴部同士を溶着させることを特徴とする、連結容器の製造方法。
- 筒状体を成形する際の成形型のうち、筒状体の開口部を成形するための口部外型をその余の部分と切り離しておき、筒状体と口部外型を係止させた状態で宙吊りにして次の工程へ移すことを特徴とする、請求項1に記載の連結容器の製造方法。
- 吹込成形型内で筒状体内に延伸棒を挿入し、延伸棒を降下させて筒状体を延伸することを特徴とする、請求項1又は2に記載の連結容器の製造方法。
- 位置決め板の移動後に、位置決め板のあとに形成された隙間へ別の補充型を挿入して吹込成形型の型窩面を完成させたのち、筒状体内に気体を圧入することを特徴とする、請求項1−3の何れか1つの項に記載の連結容器の製造方法。
- 位置決め板の先端面を吹込成形型の型窩面に合致する形状にしておき、位置決め板の先端面が吹込成形型の型窩面と面一になるまで移動させて型窩面を完成させたのち、筒状体内に気体を圧入することを特徴とする、請求項1−3の何れか1つの項に記載の連結容器の製造方法。
