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 fitment for package holding a liquid and a package including such a fitment. The fitment is a metering dispensing valve arranged to be secured to a flexible bag for selectively dispensing a metered quantity of the liquid therefrom. It includes a compressible bulb and a piercing member which when actuated pierces through the bag to enable a metered amount of the liquid to be drawn into a reservoir in the bulb. The bulb can then be compressed to dispense the metered amount of liquid from the reservoir. The dispensing valve also includes a inlet valve to ...

What is claimed is: 1. A fitment for package holding a liquid therein, said fitment being arranged for selectively dispensing an amount of the liquid from the package, the package comprising a flexible bag in which the liquid is located and having a planar wall portion bounding the liquid, said fitment being a metering dispensing valve having a body, a fluid inlet check valve, a fluid outlet check valve, a bulb, a piercing element and an outlet, said body comprising a planar flange arranged for securement to the planar wall portion of the bag, said bulb being compressible and defining a collapsible reservoir into which the amount of the liquid from the bag can be transferred for dispensing, said inlet check valve being arranged to isolate said reservoir from the bag, said outlet check valve being arranged to isolate said reservoir from said outlet, said inlet check valve being coupled to said bulb and arranged to close in response to a compression of said bulb and open in response to the release of said bulb, said outlet check valve being coupled to said bulb and arranged to open in response to the compression of said bulb and close in response to the release of said bulb, said piercing element comprising a movable tubular member coupled to said bulb and having a passageway therethrough in fluid communication with said inlet check valve, said piercing element being arranged to be moved with respect to the planar wall portion of the bag and pierce through the planar portion of the wall of the bag in response to the compression of said bulb, whereupon the amount of the liquid in the bag is drawn into said reservoir through said inlet check valve, said bulb also being arranged to be compressed after the amount of liquid is drawn into said reservoir to dispense the amount of the liquid through said outlet check valve to said outlet said fitment additionally comprising an inlet barrier and an outlet barrier, said inlet barrier being initially disposed over said inlet and said outlet barrier being initially disposed over said outlet, whereupon the interior of said fitment is initially sealed and isolated from the ambient atmosphere so that the interior of said fitment can be exposed to ionizing radiation to render its internal surfaces sterile, whereupon said fitment is ready to be secured to the wall of said bag. 2. The fitment of claim 1 wherein said inlet barrier comprises a thin membrane heat sealed over said inlet and arranged to be pierced by said piercing element. 3. The fitment of claim 1 wherein said inlet barrier comprises a thin membrane that is molded over said inlet and arranged to be pierced by said piercing element. 4. The fitment of claim 1 wherein said outlet barrier comprises a membrane releasably secured over said outlet. 5. An aseptic fitment for package holding a liquid therein, the package comprising a flexible bag having a wall, said a fitment being in the form of a metering valve comprising a body, an inlet, an inlet barrier, a fluid inlet check valve, a fluid outlet check valve, a compressible bulb, a piercing element, an outlet and an outlet barrier, said inlet barrier being disposed over said inlet and said outlet barrier being disposed over said outlet, whereupon the interior of said fitment is initially sealed and isolated from the ambient atmosphere, said fitment being arranged to be exposed to ionizing radiation to render its internal surfaces sterile and thereafter fixedly secured to the wall of the flexible bag for selectively dispensing a metered quantity of the liquid from the package, said outlet bather being arranged to be removed from said outlet, said compressible bulb defining a collapsible reservoir into which a portion of the liquid from the bag can be transferred for dispensing, said inlet valve being arranged to isolate said reservoir from the bag, said outlet valve being arranged to isolate said reservoir from said outlet, said piercing element being coupled to said compressible bulb, whereupon when said bulb is compressed it causes said piercing element to pierce through said inlet barrier and a portion of the wall of the bag, said valve being arranged when said bulb is thereafter released for automatically opening said inlet valve and closing said outlet valve, whereupon a metered amount of the liquid is drawn into said reservoir, said metering valve being further arranged so that when said bulb is compressed after the liquid is drawn into said reservoir said outlet valve is automatically opened to dispense the metered amount of the liquid through said outlet. 6. The fitment of claim 5 wherein said inlet bather comprises a thin membrane heat sealed over said inlet and arranged to be pierced by said piercing element. 7. The fitment of claim 5 wherein said inlet barrier comprises a thin membrane that is molded over said inlet and arranged to be pierced by said piercing element. 8. The fitment of claim 5 wherein said outlet barrier comprises a membrane releasably secured over said outlet. 9. A package for holding and selectively dispensing an amount of a liquid therefrom, said package comprising a flexible bag and a fitment, said bag having a hollow interior in which the liquid is located and a planar wall portion bounding the liquid, said fitment being a metering dispensing valve having a body, a fluid inlet check valve, a fluid outlet check valve, a bulb, a piercing element and an outlet, said body comprising a planar flange arranged for securement to the planar wall portion of the bag, said bulb being compressible and defining a collapsible reservoir into which the amount of the liquid from said bag can transferred for dispensing, said inlet check valve being arranged to isolate said reservoir from said bag, said outlet check valve being arranged to isolate said reservoir from said outlet, said inlet check valve being coupled to said bulb and arranged to close in response to a compression of said bulb and open in response to the release of said bulb, said outlet check valve being coupled to said bulb and arranged to open in response to the compression of said bulb and close in response to the release of said bulb, said piercing element comprising a movable tubular member coupled to said bulb and having a passageway therethrough in fluid communication with said inlet check valve, said piercing element being arranged to be moved with respect to said planar wall portion of said bag and pierce through the planar portion of said wall of said bag in response to the compression of said bulb, whereupon the amount of the liquid in said bag is drawn into said reservoir through said inlet check valve, said bulb also being arranged to be compressed after the amount of liquid is drawn into said reservoir to dispense the amount of the liquid through said outlet check valve to said outlet, said fitment additionally comprising an inlet barrier and an outlet barrier, said inlet barrier being initially disposed over said inlet and said outlet barrier being initially disposed over said outlet, whereupon the interior of said fitment is initially sealed and isolated from the ambient atmosphere so that the interior of said fitment can be exposed to ionizing radiation to render its internal surfaces sterile, whereupon said fitment is ready to be secured to said wall of said bag. 10. The package of claim 9 wherein said inlet barrier comprises a thin membrane heat sealed over said inlet and arranged to be pierced by said piercing element. 11. The package of claim 9 wherein said inlet barrier comprises a thin membrane that is molded over said inlet and arranged to be pierced by said piercing element. 12. The package of claim 9 wherein said outlet barrier comprises a membrane releasably secured over said outlet.
