Abstract

1. 청구범위에 기재된 발명의 속한 기술분야
블로우 성형방법에 의해 제조되는 용기의 투시창 성형방법.
2. 그 발명이 해결하려고 하는 기술과제
종래에는 용기를 먼저 제작하고, 완전히 성형된 상태의 용기에 투시창을 결합시키는 방법을 사용하므로써 투시창과 용기 간에 완벽한 결합이 곤란할 뿐 만 아니라, 용기에 투시창을 결합시키는 공정이 늘어나는 폐단을 갖는 것임.
3. 그 발명의 해결방법의 요지
본 발명은 주형 내벽에 고착한 투시창이 한번의 블로우공정 중에 용기와 결합되도록 하되, 파리손이 오목부에 의해 형성되는 투시창의 밀폐된 중공부에는 접하지 못하고, 바깥쪽에만 열융착이 이루어지면서 용기가 성형되도록 하여 성형된 용기의 팽창부를 절단하므로써 투시창과 용기가 관통되도록 하는 것임.
4. 발명의 중요한 용도
액상물을 충진하는 용기에 투시창을 형성하기 위한 용도임.

Description

블로우 성형방법에 의해 제조되는 용기의 투시창 성형방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 용기에 투시창을 성형하기 위한 단계를 보이기 위한 주형장치의 개략적인 종단면도로써
(a)는 개방된 상태의 주형 내벽에 투시창을 고착시킨 상태.
(b)는 개방된 주형 사이에 파리손을 압출하는 상태.
(c)는 주형을 폐쇄하고, 주형 내부에 공기를 취입하여 용기가 성형되는 상태.
(d)는 파리손이 투시창을 감싸면서 투시창의 측면과 융착되는 상태.
(e)는 용기가 성형된 후 주형이 개방되고, 상기 주형으로부터 축출된 용기 내부에 팽창부가 형성된 상태.
제2도는 용기 내부에 형성된 팽창부와 돌기를 절단한 후 내용물이 충진된 용기의 사용상태를 보이기 위한 종단면도.
