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.

A fluid dispenser is described that includes a dispenser, a cap, and an insert. The dispenser is flexible and includes a body portion and a cylindrical mouth portion extending from the body portion. The mouth portion has an opening defining a lip. The cap is operable to engage the mouth portion of the dispenser, said cap has an aperture therethrough operable to dispense a fluid stored within the dispenser. The insert is sized for placement within the opening, between the mouth portion and the cap and includes a substantially solid plug having a first and a second axial hole therethrough, a first reed valve operably attached to the plug to close the first axial hole from an outside of the dispenser, and a second reed valve operably attached to the plug to close the second axial hole from an inside of the dispenser.

1. A fluid dispenser comprising: a dispenser comprising a flexible material, said dispenser comprising a body portion and a cylindrical mouth portion extending from said body portion, said mouth portion comprising an opening defining a lip extending about said opening;a cap operable to engage said mouth portion of said dispenser, said cap comprising an aperture therethrough operable to dispense a fluid stored within said dispenser; anda cylindrical insert sized for placement within said opening between said mouth portion and said cap, said cylindrical insert comprising: a substantially solid plug comprising a first axial hole extending therethrough, a second axial hole extending therethrough, and a protrusion extending about a perimeter of said plug to engage said mouth portion lip at a distal end of said mouth portion that is furthest from said body portion;a first reed valve operably attached to said plug to close said first axial hole from an outside of said dispenser;a second reed valve operably attached to said plug to close said second axial hole from an inside of said dispenser;a reed retainer operable to place a positive pressure onto said first reed valve with respect to said first axial hole; anda fastener attaching said first reed valve and said reed retainer to said plug, said fastener extending through a first aperture formed in said first reed valve and a second aperture formed in said reed retainer. 2. The fluid dispenser of claim 1 wherein said reed retainer comprises aluminum. 3. The fluid dispenser of claim 1, wherein said fastener comprises a threaded fastener, said threaded fastener operable to threadably engage said plug to maintain an orientation of said first reed valve and said reed retainer. 4. The fluid dispenser of claim 1 wherein said first reed valve and said second reed valve comprise steel. 5. The fluid dispenser of claim 1 wherein said first reed valve is operable to deflect away from said plug when a positive pressure is placed on said dispenser to allow a fluid to pass from said dispenser, through said first axial hole, and said aperture of said cap. 6. The fluid dispenser of claim 1 wherein said second reed valve is operable to deflect away from said plug when a negative pressure is placed on said dispenser to allow a fluid to pass into said dispenser, through said aperture of said cap and said second axial hole. 7. The fluid dispenser of claim 1 wherein said substantially solid plug comprises a plastic. 8. The fluid dispenser of claim 1 wherein said dispenser is approximately hand sized, and wherein said first reed valve and said second reed valve comprise a steel of about 0.003 inch in thickness. 9. The fluid dispenser of claim 1 wherein said protrusion forms a washer between said dispenser and said cap. 10. The fluid dispenser of claim 1 wherein said substantially solid plug comprises a recessed area, said first reed valve operably attached to said recessed area. 11. The fluid dispenser of claim 1 wherein said first reed valve comprises a biasing force for closing said first axial hole and said second reed valve comprises a biasing force for closing said second axial hole. 12. An insert sized for placement within an opening of a dispenser defined by a lip, said insert having a cylindrical shape and comprising: a substantially solid plug comprising a first surface, a second surface, a first axial hole extending from said first surface to said second surface, a second axial hole extending from said first surface to said second surface, and a protrusion extending about a perimeter of said plug and configured to engage the lip of the dispenser at a distal end of the dispenser that is furthest from a body portion of the dispenser;a first reed valve operably attached to said first surface of said plug to close said first axial hole;a second reed valve operably attached to said second surface of said plug to close said second axial hole;a reed retainer operable to place a positive pressure onto said first reed valve with respect to said first axial hole; anda fastener attaching said first reed valve and said reed retainer to said first surface, said fastener extending through a first aperture formed in said first reed valve and a second aperture formed in said reed retainer. 13. The insert according to claim 12 wherein said reed retainer comprises aluminum, said first reed valve and said second reed valve comprise steel, and said plug comprises plastic. 14. The insert according to claim 12 wherein: said first reed valve is operable to deflect away from said first surface when a positive pressure, originating proximate said second surface, is applied through said first axial hole; andsaid second reed valve is operable to deflect away from said second surface when a positive pressure, originating proximate said first surface, is applied through said second axial hole. 15. A method for dispensing a fluid from a flexible dispenser comprising: applying a positive pressure to the dispenser to force the fluid through a first axial hole formed in a plug placed in an opening of the dispenser defined by a lip, the pressure causing a first reed valve mounted on a side of the plug opposite the fluid storage to move away from the first axial hole to allow the fluid to pass through, the positive pressure further causing a second reed valve on a side of the plug where the fluid is contained to maintain placement to substantially seal a second axial hole formed in the plug, wherein the plug includes a protrusion that engages the lip of the dispenser at a distal end of the dispenser that is furthest from a body portion of the dispenser;utilizing a reed retainer to bias the first reed valve towards the first axial hole, wherein a fastener couples the first reed valve and the reed retainer to the plug, the fastener extending through a first aperture formed in the first reed valve and a second aperture formed in the reed retainer;releasing the positive pressure to allow the first reed valve to return to a position that substantially seals the first axial hole and allows the second reed valve to open thereby allowing air to enter the dispenser through the second axial hole until a difference in pressure between an interior and an exterior of the dispenser is reduced to substantially zero; andallowing the second reed valve to substantially reseal the second axial hole.
