연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An easy-open container end includes a displaceable panel defined by a score line having curved tails which is in parallel relationship with adjacent means for reinforcing, thereby reducing opening failures, while controlling tearing. A score die and anvil is further provided wherein a four bolt pattern provides greater resistance to distortion and more even mounting stress distribution, resulting in more even score line residuals and reduced opening failures.

청구항

An easy-open container end comprising: an end wall adapted for attachment to a container body; and a displacable panel defined in said end wall by a rupturable score line having first and second ends, and an unscored hinge area defined between said first and second ends connecting said panel to said end wall; said rupturable score line further including first and second tail portions at said first and second ends, respectively, curving inward towards said hinge area; whereby an opening tab may be pivoted to exert axial pressure on a portion of said panel...
