- 플라스틱 원료 수지를 사출하여 중간 제품인 프리폼을 만들고, 블로우 공정에서 상기 프리폼을 원료 수지의 유리전이온도 이상까지 적외선 히터를 사용하여 재가열한 후, 가열된 프리폼을 성형 몰드에 넣고 고압으로 블로우하여 용기로 성형시키는 플라스틱 용기의 제조방법에 있어서, 상기 프리폼의 적외선 히터에 의한 재가열과정은 적어도 하나의 공기 통로를 갖는 불투명 재질로 된 적어도 하나의 인서어트(insert)를 상기 프리폼의 내부에 삽입한 상태로 수행되며, 상기 공기 통로를 통해서 가열된 공기가 불어넣어져 순환되는 것을 특징으로 하는 플라스틱 용기의 제조방법.
- 제1항에 있어서, 상기 인서어트는 종방향의 공기 통로, 횡방향의 공기 통로 또는 이들이 조합되어 형성된 적어도 하나의 공기 통로를 갖는 것을 특징으로 하는 플라스틱 용기의 제조방법.
- 제1항에 있어서, 상기 가열된 공기는 상기 적외선 히터 주변의 가열된 공기로부터 공급되며, 상기 가열된 공기는 상기 인서어트 내부의 적어도 하나의 공기 통로를 통해서 인서어트와 프리폼 사이의 공간을 통과하여 순환되는 것을 특징으로 하는 플라스틱 용기의 제조방법.
- 제1항에 있어서, 상기 가열된 공기는 별도의 가열장치로부터 공급되며, 상기 가열된 공기는 상기 인서어트 내부의 적어도 하나의 공기 통로를 통해서 인서어트와 프리폼 사이의 공간을 통과하여 순환되는 것을 특징으로 하는 플라스틱 용기의 제조방법.
- 제1항에 있어서, 상기 인서어트의 재질은 상기 플라스틱 용기의 가공시 변형이 일어나지 않는 것임을 특징으로 하는 플라스틱 용기의 제조방법.
- 제1항 또는 제5항에 있어서, 상기 인서어트의 재질은 금속, 종이 또는 합성수지임을 특징으로 하는 플라스틱 용기의 제조방법.
