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 package, a fitment and method for dispensing a flowable material is disclosed. The package includes a hollow body formed of a flexible material and a fitment secured thereto. The fitment includes an outer gland and a plunger and overlies a frangible penetration zone in the hollow body of the package. The outer gland includes a passageway extending through it. The plunger has a cylindrical wall defining a hollow interior and a free end disposed within the passageway of the gland. The plunger is arranged to be moved along the passageway, so that its free end penetrates through the penetration zone into the interior of the package to provide an exit port for the material. The free end of the plunger also serves to hold portions of the walls of the package away from the exit port to prevent blockage thereof.

1. A package including a fitment which when operated enables the dispensing of a flowable material from said package, said package comprising a hollow body and said fitment, said hollow body comprising of a first wall portion and a second wall portion and a cavity located between said first and second wall portions for holding the flowable material therein, said wall portions being formed of a flexible material, with said first wall portion having an exterior surface and a frangible penetration zone, said fitment being located on said exterior surface with no portion of said fitment being located within said cavity, whereupon said frangible penetration zone of said first wall portion is able to be engaged by said second wall portion without interference of any portion of said fitment, said fitment comprising an outer gland and a plunger, said outer gland comprising a flange fixedly secured to said exterior surface of said first wall portion and a passageway extending through said outer gland, said passageway overlying said penetration zone, said plunger comprising a cylindrical wall defining a hollow interior and a free end disposed within said passageway, said plunger being arranged to be moved longitudinally along said passageway relative to said flange when said fitment is operated, whereupon said free end of said plunger moves with respect to said flange and penetrates through said penetration zone to enter said cavity to provide fluid communication between said cavity and said interior of said plunger, said free end of said plunger being arranged to directly engage said second wall portion to hold said second wall portion in a spaced relationship to said first wall portion at said penetration zone after said penetration zone has been penetrated by said plunger and said free end of said plunger has entered said cavity. 2. The package of claim 1 wherein said penetration zone comprises at least one cut or perforation. 3. The package of claim 1 wherein said hollow interior of said plunger is arranged to releasably receive a tube of an associated dispensing device. 4. The package of claim 1 wherein said plunger includes at least one opening adjacent said free end into which said flowable material can flow. 5. The package of claim 4 wherein said free end of said plunger comprises a generally planar end wall. 6. The package of claim 5 wherein said cylindrical sidewall of said plunger includes said at least one opening. 7. The package of claim 1 wherein said outer gland comprises a cylindrical side wall, said cylindrical side wall forming said passageway. 8. The package of claim 7 wherein said plunger additionally comprises a collar arranged to extend about said cylindrical side wall. 9. The package of claim 8 wherein said hollow interior of said plunger is arranged to releasably receive a tube of an associated dispensing device. 10. A fitment for securement to package for enabling the dispensing a flowable material therefrom when said fitment is operated, the package comprising hollow body having a first wall portion, a second wall portion and a cavity located between the first and second wall portions for holding the flowable material therein, the wall portions being formed of a flexible material, with the first wall portion having an exterior surface and a frangible penetration zone, said fitment being located on the exterior surface with no portion of said fitment being located within the cavity, whereupon the frangible penetration zone of the first wall portion is able to be engaged by the second wall portion without interference of any portion of said fitment, said fitment comprising an outer gland and a plunger, said outer gland comprising a flange arranged to be fixedly secured to the exterior surface of the first wall portion and a passageway extending through said outer gland, said passageway overlying the penetration zone, said plunger comprising a cylindrical wall defining a hollow interior and a free end disposed within said passageway, said plunger being arranged to be moved longitudinally along said passageway relative to said flange when said fitment is operated, whereupon said free end of said plunger moves with respect to said flange and penetrates through the penetration zone to provide fluid communication between the cavity and said interior of said plunger, said free end of said plunger being arranged to directly engage the second wall portion to hold the second wall portion in a spaced relationship to the first wall portion at said penetration zone after the penetration zone has been penetrated by said plunger and said free end of said plunger has entered the cavity. 11. The fitment of claim 10 wherein said hollow interior of said plunger is arranged to releasably receive a tube of an associated dispensing device. 12. The fitment of claim 10 wherein said plunger includes at least one opening adjacent said free end into which said flowable material can flow. 13. The fitment of claim 12 wherein said free end of said plunger comprises a generally planar end wall. 14. The fitment of claim 13 wherein said cylindrical sidewall of said plunger includes said at least one opening. 15. The fitment of claim 10 wherein said outer gland comprises a cylindrical side, said cylindrical side wall forming said passageway. 16. The fitment of claim 15 wherein said plunger additionally comprises a collar arranged to extend about said cylindrical side wall. 17. The fitment of claim 16 wherein said hollow interior of said plunger is arranged to releasably receive a tube of an associated dispensing device. 18. A method for dispensing a flowable material from a flexible package by operation of a fitment, said method comprising: providing a flexible package comprising a hollow body and said fitment, said hollow body comprising of a first wall portion and a second wall portion and a cavity located between said first and second wall portions for holding the flowable material therein, said wall portions being formed of a flexible material, with said first wall portion having an exterior surface, and a frangible penetration zone, said fitment being located on said exterior surface with no portion of said fitment being located within said cavity, whereupon said frangible penetration zone of said first wall portion is able to be engaged by said second wall portion without interference of any portion of said fitment, said fitment comprising an outer gland and a plunger, said outer gland comprising a flange fixedly secured to said exterior surface of said first wall portion and a passageway extending through said outer gland, said passageway overlying said frangible penetration zone of said first wall portion, said plunger comprising a cylindrical wall defining a hollow interior and a free end disposed within said passageway; andoperating said fitment to move said plunger longitudinally along said passageway relative to said flange to cause said free end of said plunger to penetrate through said penetration zone to enter said cavity to provide fluid communication between said cavity and said interior of said plunger and with free end of said plunger directly engaging said second wall portion to hold said second wall portion in a spaced relationship to said first wall portion at said penetration zone after said penetration zone has been penetrated by said plunger and said free end of said plunger has entered said cavity. 19. The method of claim 18 additionally comprising connecting a tube of a dispensing apparatus to said plunger to cause said flowable material to flow into said tube. 20.
