Abstract

본 발명은 적층용기 제조방법 및 이를 이용한 적층용기에 관한 것으로, 외층과 내층을 형성하기 위한 수지를 제 1 압출기를 통해 금형에 주입하는 제 1 주입단계와, 상기 제 1 주입단계 후 외층과 내층 사이에 중간층을 형성하기 위한 수지를 제 2 압출기를 통해 금형에 주입하는 제 2 주입단계와, 상기 제 2 주입단계 후 용기의 외형을 형성하는 성형단계와, 상기 성형단계 후 용기의 입구를 밀폐한 상태에서 용기 내부의 공기를 배기시켜 중간층에서 내층을 박리시키고 수축시키는 내층 수축단계를 포함하는 적층용기 제조방법이 제공된다. 이에 따라서, 적층용기에서 층간에 접착층이 없는 적층용기를 제조할 수 있어 제조원가를 낮출 수 있으며, 숨구멍을 형성하기 위한 별도의 후처리 가공이 필요없고 숨구멍 형성과 동시에 내층의 파손 여부를 확인할 수 있어 적층용기의 생산성을 향상시킬 수 있는 효과가 있다.
