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.

A dispensing system having a reverse taper dispensing orifice seal. The reverse tapered seal depends from a lid of a flip-top closure providing a sealing engagement with a dispensing spout of the flip-top closure body when in a closed position. As the dispensing spout may have a variety of shapes, the reverse tapered seal is shaped to conform to the irregularities of the contacted surfaces of the dispensing spout. The decreasing thickness of the reverse tapered seal decreases the complexity of the molding process as well as minimizing the weakening or br...

The flip-top closure as in claim 1 wherein said closure body includes an outer shell and an inner shell depending from said top wall of said closure body and said outer shell and said inner shell being interconnected by a plurality of gussets. 3. The flip-top closure as in claim 2 wherein said inner shell includes at least one depending drop lug. 4. The flip-top closure as in claim 2 wherein said raised elongated spout having a pair of elongated lateral walls that are non-parallel. 5. The flip-top closure as in claim 1 wherein said top wall of said closure body includes a depending plug seal engaging an interior surface of a container neck opening. 6. The flip-top closure as in claim 1 wherein the entire said second length of said seal depends at said acute angle from said lid. 7. The flip-top closure as in claim 1 wherein said closure body and said lid are oval in shape. 8. The flip-top closure as in claim 1 wherein said lid has a flat top surface. 9. The flip-top closure as in claim 1 further comprising a front lift point. 10. A flip-top closure with a reverse taper dispensing orifice seal comprising: a flip-top closure body having a top wall, said top wall having a top surface with a raised elongated spout projecting therefrom, said raised elongated spout having an opposed ovalized outer surface and an opposed ovalized inner surface defining an orifice through said top wall, said outer surface of said spout is substantially vertical; said top wall including a depending inner shell and an outer shell, said inner shell adapted to engage the neck of a container and said inner shell including at least one depending drop lug adapted to engage the lug stop integrally formed on the neck of the container and said top wall having a depending plug seal adapted to engage the opening of the container neck; said closure body having a flip-top lid hingedly attached thereto; said lid having a depending sleeve and a depending plug, said depending sleeve positioned to engage said outer surface of said raise elongated spout when said lid is closed upon said closure body, said sleeve having a first end adjacent said flip-top lid and a distal end opposite therefrom; said distal end of said sleeve having an inner surface and an outer surface, each of said inner surface and said outer surface of said distal end angularly positioned at an acute angle relative to the vertical axis of said orifice through said top wall, wherein said outer surface of said distal end is smaller in diameter than an outer surface of said first end of said sleeve and said inner surface of said distal end is smaller in diameter than an inner surface of said first end of said sleeve; said acutely angled distal end tapering from a first thickness to a second thickness in a direction away from said first end of said sleeve, wherein said first thickness is larger than said second thickness; said acutely angled distal end of said seal creating a line contact seal about the periphery of said substantially vertical outer surface of said raised elongated spout; said plug having a first length and said sleeve having a second length, wherein said first length is greater than said second length, said plug engaging said inner surface of said raised elongated spout and urges said outer surface of said raised elongated spout outwardly against said sleeve distal end enhancing said line contact seal about the periphery of said closure raised elongated spout when said lid is closed upon said closure body. 11.
