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 liquid applicator of claim 1, wherein the actuation means is removably or irremovably coupled to the container. 3. A liquid applicator of claim 1, wherein the actuation means is axially displaceable along the longitudinal axis of the liquid applicator. 4. A liquid applicator of claim 1, wherein the biasing member can be made up of metal, alloy or a thermoplastic polymer capable of providing resilient properties to the biasing member. 5. A liquid applicator of claim 1, wherein the bottom wall of the plug comprises a raised cylindrical post having an annular groove, a top surface and a radially extended circular rim, wherein the annular groove provides a guide path for the movement of the flow control unit. 6. A liquid applicator of claim 5, wherein the peripheral wall of the plug comprises on its inner side, at least one inwardly projected wall surface touching a top surface of the bottom wall of the plug, wherein the at least one inwardly projected wall surface results in the formation of a longitudinal furrow providing a path for the flow of the liquid content there through. 7. A liquid applicator of claim 6, wherein flow control unit comprises of a cylindrical wall portion, a conically tapered wall portion which tapers towards the top end, an annular projection at the bottom end, at least two flange discs on the cylindrical wall portion and wherein each of the two flange discs comprises a flat surface such that the flat surfaces do not completely circumscribe the cylindrical wall portion of the flow control unit. 8. A liquid applicator of claim 7, wherein each of the two flange discs of the flow control unit is in close proximity to the inner side of the peripheral wall of the plug. 9. A liquid applicator of claim 8, wherein the biasing member is enclosed within the cylindrical wall portion of the flow control unit and rests against the top surface of the cylindrical post of the bottom wall of the plug. 10. A liquid applicator of claim 9, wherein the collar holder comprises of a hollow cylindrical body having an open top end and an open bottom end, wherein the bottom end of the collar holder abuts on the flat surface of each of the two flange discs of the flow control unit. 11. A liquid applicator of claim 10, wherein the hollow cylindrical body of the collar holder comprises on its outer side, an annular flange at an appropriate position and an annular groove; wherein the annular groove further has a top end and a bottom end and wherein the annular groove is extended in a longitudinal direction up to a predetermined length. 12. A liquid applicator of claim 11 further comprises a collar attached to the collar holder, an application member attached to the collar, and a discharge barrel attached inside the collar holder for flow of the liquid content to the application member. 13. A liquid applicator of claim 12, wherein the actuation means includes threads on its inner side and a sealing flange above the threads; and wherein the actuation means is threadedly engaged to the mouth portion of the container. 14. A liquid applicator of claim 13, wherein in the closed position of the liquid applicator, the annular projection at the bottom end of the flow control unit sits in an annular furrow in the bottom wall of the plug to close the at least one aperture in a bottom surface of the bottom wall of the plug. 15. A liquid applicator of claim 14, wherein in the closed position of the liquid applicator, the top end of the annular groove of the collar holder abuts against an annular projection on an inner side of the peripheral wall of the plug. 16. A liquid applicator of claim 15 wherein, in the open position of the liquid applicator, the bottom end of the annular groove of the collar holder abuts against the annular projection on the inner side of the peripheral wall of the plug. 17. A liquid applicator of claim 16 wherein, in the open position of the liquid applicator, the inner side at the bottom end of the peripheral wall of the cylindrical portion of the flow control unit abuts against the radially extended circular rim of the post of the plug. 18. A liquid applicator comprising: a container comprising a main body containing a liquid content and a mouth portion;a plug fitted into an opening of the mouth portion, wherein the plug comprises a peripheral wall defining a hollow space and a bottom wall with at least one aperture;a flow control unit arranged to be moved inside the hollow space of the plug along a longitudinal axis of the liquid applicator, wherein the flow control unit comprises a cavity;a biasing member placed inside the cavity of the flow control unit providing an upward biasing force to the flow control unit;a collar holder arranged to be moved inside the hollow space of the plug along the longitudinal axis of the liquid applicator;a cap removably engaged to the mouth portion of the container, the cap is configured to displace the collar holder along the longitudinal axis of the liquid applicator to bring the liquid applicator to a closed position and to an open position;wherein to bring the liquid applicator to the closed position, the cap is displaced axially in a downward direction to displace the collar holder and the flow control unit axially in the downward direction along the longitudinal axis counter to the upward biasing force of the biasing member;wherein to bring the liquid applicator to the open position, the cap is displaced axially in the upward direction so that the upward biasing force of the biasing member displaces the collar holder and the flow control unit axially in the upward direction along the longitudinal axis;wherein, in the closed position, the flow control unit closes the at least one aperture in the plug;wherein, in the open position, the flow control unit opens the at least one aperture in the plug and the liquid content flows from the container through the at least one aperture to the collar holder such that the container, the plug and the collar holder are in fluid communication with each other; andwherein in the open position of the liquid applicator, the liquid content does not enter into the cavity of the flow control unit. 19. A liquid applicator comprising: a container comprising a main body containing a liquid content and a mouth portion;a plug fitted into an opening of the mouth portion, wherein the plug comprises a peripheral wall defining a hollow space and a bottom wall with at least one aperture;a flow control unit arranged to be moved inside the hollow space of the plug along a longitudinal axis of the liquid applicator, wherein the flow control unit comprises a cavity;a biasing member placed inside the cavity of the flow control unit providing an upward biasing force to the flow control unit;a collar holder arranged to be moved inside the hollow space of the plug along the longitudinal axis of the liquid applicator;a jacket engaged to the mouth portion of the container, the jacket is configured to displace the collar holder along the longitudinal axis of the liquid applicator to bring the liquid applicator to a closed position and to an open position;wherein to bring the liquid applicator to the closed position, the jacket is displaced axially in a downward direction to displace the collar holder and the flow control unit axially in the downward direction along the longitudinal axis counter to the upward biasing force of the biasing member;wherein to bring the liquid applicator to the open position, the jacket is displaced axially in an upward direction so that the upward biasing force of the biasing member displaces the collar holder and the flow control unit axially in the upward direction along the longitudinal axis;wherein, in the closed position, the flow control unit closes the at least one aperture in the plug;wherein, in the open position, the flow control unit opens the at least one aperture in the plug;wherein, in the open position, the container, the plug and the collar holder are in fluid communication with each other; and wherein in the open position of the liquid applicator, the liquid content does not enter into the cavity of the flow control unit. 20.
