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 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.

The dispensing closure set forth in claim 9 wherein said arcuate cross section of said channel varies in radius around said central portion. 11. The dispensing closure set forth in claim 9 wherein said domed central portion of said deck has a greatest height equal to said greatest height of said raised wall. 12. The dispensing closure set forth in claim 9 including interlocking beads on said lid and said base for holding said lid in a closed position over said base. 13. The dispensing closure set forth in claim 9 wherein said base includes inner and outer skirts extending from said deck, and radial ribs integrally interconnecting said skirts. 14. The dispensing closure set forth in claim 9 wherein said deck has an annular wall underlying said deck around said dispensing opening and an annular channel on an undersurface of said deck interiorly adjacent to said annular wall, wherein said valve has a peripheral ledge with a bead received in said channel, and wherein a retaining ring is secured within said annular wall and captures said peripheral ledge between said ring and said undersurface of said deck. 15. The dispensing closure set forth in claim 14 wherein a central portion of said valve is angled inwardly from said dispensing opening, and wherein said lid has an annular bead that is received between said central portion of said valve and an inner periphery of said dispensing opening in a closed position of said lid over said base. 16. The dispensing closure set forth in claim 15 wherein said valve has an external bead around said central portion adjacent to said peripheral ledge for engaging and temporarily holding said valve within said dispensing opening until said retaining ring is secured to said base. 17. The dispensing closure set forth in claim 14 wherein said retaining ring includes a collar and a flange extending radially outwardly from said collar, said retaining ring being symmetrical on opposite sides of said flange. 18. The dispensing closure set forth in claim 17 including nubs on said flange for engaging said peripheral ledge of said valve. 19. A dispensing package for fluid products, which includes: a container having a body for holding a product to be dispensed and a finish extending from said body, and a dispensing closure that includes: a base having a lid integrally connected to said base by a hinge, said base having a deck with a central portion, a dispensing opening and a peripheral portion surrounding said central portion, said central portion of said deck being domed and having a greatest height at said dispensing opening, said peripheral portion including a raised wall partially surrounding said central portion, said raised wall having its greatest height adjacent to said hinge and decreasing in height around said central portion, said wall having an inner surface that blends with said central portion to form a concave channel surrounding said central portion, said channel surface having a base that is angled with respect to said peripheral portion down and away from said wall. 20.
