Description

콘테이너용 폐쇄마개와 그마개의 카스켓형성 조성물
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (13)

  1. 카스켓을 폴리프로필렌제마개에서 형성하기 위하여 그마개내에서 성형하는 데 적당한 열가소성 폴리머 조성물에 있어서, 가스켓이형재(gasket-releasing material)가 없도록 구성하며, 용융점 160℃ 이하이고 그 열가소성 폴리머조성물을 60wt% 이하인 양으로 구성시켜, 200℃ 이하의 온도로 상기 마개에서 성형한 가스켓이 그마개에 직접 접착되도록 구성하는 접착을 촉진시키는 프로필렌폴리머를 포함시킴을 특징으로하는 상기 조성물.
  2. 제 1 항에 있어서, 상기 프로필렌폴리머는 프로필렌 호모폴리머 또는 40%까지의 에틸렌과 프로필렌의 코폴티머임을 특징으로하는 상기 조성물.
  3. 제 1 항에 있어서, 상기 프로필렌 폴리머는 2-10%의 에틸렌과 프로필렌의 코폴리머임을 특징으로 하는 상기 조성물.
  4. 제 1 항 내지 3항중 어느 한항에 있어서, 상기 프로필렌폴리머는 산변성 프로필렌폴리머(acid modified propylene polymer)임을 특징으로하는 상기 조성물.
  5. 제 1 항 내지 제 4 항중 어느 한항에 있어서, 상기 프로필렌폴리머는 융점이 125-155℃의 범위임을 특징으로하는 상기 조성물.
  6. 제 1 항 내지 제 5 항중 어느 한항에 있어서, 상기 조성 물에서 상기 프로필렌폴리머의 량은 10-30wt%의 범위 임을 특징으로 하는 상기 조성물.
  7. 제 1 항 내지 제 6 항중 어느 한항에 있어서, 상기 프로필렌폴리머와, 폴리에틸렌, 에틸렌비닐아세테이트 및 그 혼합물에서 선택된 다른 열가소성 폴리머의 혼합물로 구성됨을 특징으로 하는 상기 조성물.

  9. 마개내에서 열가소성폴리머조성물로 200℃ 이하의 온도로 성형한 가스켓을 가진 폴리프로필렌제마개에 있어서, 상기 가스켓은 폴리프로필렌제마개의 직접 접착하며, 가스켓이형재가 없으며 융점이 160℃ 이하이고 열가소성폴리머조성물이 60wt% 이하인량으로 존재하는 접착을 촉진시키는 프로필렌폴리머를 포함하는 열가소성 폴리머조성물에서 형성됨을 특징으로하는 상기 폴리프로필렌제마개.
  10. 제 9 항에 있어서, 상기 가스켓은 상기 제1항 내지 제8항증 어느 한항에 의한 조성물에 형성됨을 특징으로하는 상기 마개.
  11. 열가소성 폴리머조성물을 폴리프로필렌제마개에서 용융압출시켜 그조성물로 그마개에서 성형하여 열가소성폴리머조성물로된 가스켓을 성형하는 방법이 있어서, 상기 성형은 200℃ 이하의 온도에서 실시하며, 상기 가스켓은 폴리프로필렌제 마개에 직접 부착하며 가스켓이형재가 실제로 없으며, 용융점이 160℃ 이하이고 열가소성폴리머조성물이 60wt% 이하인량으로 존재하는 접착촉진 프로필렌폴리머를 포함한 열가소성폴리머 조성물부터 형성됨을 특징으로 하는 상기 방법.
  12. 제 1 항에 있어서, 상기 성형은 140-190℃의 온도범위에서 실시함을 특징으로하는 상기 방법.
  13. 제11항 또는 제12항에 있어서, 상기 열가소성폴리머조성물은 청구범위 제 1 항 내지 제 8 항중 어느 한 항에 의한 조성물임을 특징으로하는 상기방법.
