본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 바닥과 목금형으로 사출성형된 패리슨(pasison)의 종단면도.
제2도는 스트레치 블로우 성형된 중간부와 목금형의 종단면도.
제3도는 확장된 부분을 절단함으로써 형성된 캔체의 종단면도.
제4도는 확장된 부분의 절단부를 나타내는 부분단면도.
제5도는 캔체에 이어맞춘 캔뚜껑과 함께 제조될 수 있는 합성수지 캔의 정면도.

Claims (4)

  1. 폴리에틸렌-테레프탈레이트와 같은 열가소성수지로 형성된 바닥이 있는 패리슨을 사출 또는 압출성형에 의하여 성형하는 단계와, 상기 패리슨을 미리 준비된 블로우 금형과 스트레치 막대를 사용하면서 몸체부분을 더욱 더 밖으로 팽창시킴으로써 상기 몸체부분의 상부끝에 형성된 동심원의 형태로 연속적으로 확장된 부분을 갖는 쌍축배향된 병모양 중간체로 형성시키는 단계와, 상기 중간부위를 상기 확장된 부분의 하부끝에서 상기 중간부위를 절단하는 단계, 그리고 몸체부분의 열린 주위 테두리가 상기 하부쪽에 의하여 측면으로 쌍축향배된 플랜지를 가지면서 바닥과 몸체 부분이 서로 완전히 캔체를 얻는 단계로 이루어지는 것을 특징으로 하는 합성수지 캔체의 제조방법.
  2. 제1항에 있어서, 상기 중간부위를 스트레치 블로우 성형하는데 있어서, 체벽과 하부쪽의 연결부분의 강도를 증가시키기 위하여 몸체부분의 상부끝은 안쪽으로 굽어지고 상기 확장된 부분의 상기 하부쪽의 연결되며 얕은 홈을 받는 이음매는 몸체부분의 상부끝에 형성되는 것을 특징으로 하는 합성수지 캔체의 제조방법.
  3. 제1항에 있어서, 상기 중간부위를 스트레치 블로우 성형하는데 있어서, 상기 확장된 부분의 측벽이 팽창되어 성형되는 것을 특징으로 하는 합성수지 캔체의 제조방법.
  4. 제1항에 있어서, 상기 중간부위를 스트레치 블로우 성형하는데 있어서, 상기 확장된 부분의 상부를 형성하는 패리슨의 입구부분의 아래쪽은 다른 부분의 온도보다 더 높은 온도로 가열되고 중간부위를 성형하는 시기에 확장된 부분의 상부는 수지의 양을 절감하기 위하여 벽두께가 얇게 형성되는 것을 특징으로 하는 합성수지 캔체의 제조방법.
