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 slider is adapted for use with a reclosable fastener for bags containing material. The reclosable fastener includes a first track and a second track. The first track includes a first profile, while the second track includes a second profile. The first and second profiles are releasably engageable to each other. At least one of the first and second profiles has an interior portion. The slider comprises a body that includes a top, a first side, a second side and a separation member on an underside of the top. The separation member is adapted to open and close the fastener and includes a slider finger that extends generally downwardly from the top. The slider finger extends into an interior portion of the first profile so as to assist in removing material trapped in the interior portion of the first profile when closing the reclosable fastener.

What is claimed is: 1. A reclosable fastener for use with bags having an interior space adapted to receive material, the reclosable fastener comprising: a first track comprising a first profile having an interior area, the first profile having a generally thin walled deflection shield that prevents or inhibits material from entering the interior area of the first profile; and a second track comprising a second profile, the first and second profiles being releasably engageable to each other by having a portion of the second profile enter the interior area of the first profile, wherein a portion of the generally thin walled deflection shield is adapted to break, rupture or slit in response to a portion of the second profile entering the interior area of the first profile. 2. The fastener of claim 1, wherein the generally thin walled deflection shield is formed by a seam portion. 3. The fastener of claim 2, wherein the seam portion is thinner than the remainder of the generally thin wall deflection shield. 4. The fastener of claim 1, wherein the first profile forms a general c-shape that includes at least two extensions having respective ends, the generally thin walled deflection shield attached to and extending between the respective ends. 5. The fastener of claim 4, wherein the generally thin walled deflection shield is perpendicular to the respective ends. 6. The fastener of claim 1, wherein the generally thin walled deflection shield upon breaking, rupturing or slitting in response to a portion of the second profile entering the interior area of the first profile forms two deflection shields. 7. The fastener of claim 1, wherein the first profile is integrally formed. 8. The fastener of claim 1, wherein the generally thin wall deflection shield is flexible. 9. The fastener of claim 1, wherein the generally thin wall deflection shield has a thickness of from about 0.5 to about 10 mils. 10. The fastener of claim 1, wherein the generally thin walled deflection shield is formed by a seam portion, the seam portion has a thickness of from about 0.2 to about 8 mils. 11. The fastener of claim 10, wherein the seam portion has a thickness of from about 1 to about 4 mils. 12. The fastener of claim 1, wherein the generally thin wall deflection shield comprises at least one polyolefin. 13. The fastener of claim 12, wherein the generally thin wall deflection shield comprises polyethylene, polypropylene, or combinations thereof. 14. A reclosable fastener for use with bags having an interior space adapted to receive material, the reclosable fastener comprising: a first track comprising a first profile, the first profile being a general c-shape in the open position and further including two generally thin walled deflection shields, the general c-shape being formed from two extensions spaced apart and attached to a first portion, the two extensions having respective outer ends each spaced from the first portion, each of the two generally thin walled deflection shields being attached or formed near a respective one of the outer ends of the two extensions so as to prevent or inhibit material from entering the interior area of the first profile when the reclosable fastener is in an open position; and a second track comprising a second profile, the first and second profiles being releasably engageable to each other, wherein the generally thin walled deflection shields are spaced slightly apart so as to form a gap and to allow a portion of the second profile to enter into the interior area formed by the general c-shape section, and wherein the two generally thin walled deflection shields extend generally perpendicular from a respective one of the outer ends of the two extensions when the first and second profiles are not releasably engaged to each other, the two generally thin walled deflection shields being generally coplanar with each other when the first and second profiles are not releasably engaged to each other, wherein the thickness of the gap is substantially less than the thickness of the general c-shape section and wherein the thickness of the two generally thin walled deflection shields is substantially less than the thickness of the general c-shape section. 15. The fastener of claim 14, wherein each of the generally thin walled deflection shields is perpendicular to a respective end thereof when the first and second profiles are not releasably engaged to each other. 16. The fastener of claim 14, wherein the first profile is integrally formed. 17. The fastener of claim 14, wherein the generally thin wall deflection shields are flexible. 18. The fastener of claim 14, wherein the generally thin walled deflection shields have a thickness of from about 0.2 to about 10 mils. 19. The fastener of claim 14, wherein the generally thin wall deflection shields comprise at least one polyolefin. 20. The fastener of claim 19, wherein the generally thin wall deflection shields comprise polyethylene, polypropylene, or combinations thereof 21. A reclosable fastener for use with bags having an interior space adapted to receive material, the reclosable fastener comprising: a first track comprising a first profile, the first profile being a general c-shape in the open position and further including two generally thin walled deflection shields, the general c-shape being formed from two extensions spaced apart and attached to a first portion, the two extensions having respective outer ends each spaced from the first portion, each of the two generally thin walled deflection shields being attached or formed near a respective one of the outer ends of the two extensions so as to prevent or inhibit material from entering the interior area of the first profile when the reclosable fastener is in an open position, the first track extending in a direction from one of the outer ends in an opposite direction from the interior area; and a second track comprising a second profile, the first and second profiles being releasably engageable to each other, the second track extending in a direction from the other one of the outer ends in an opposite direction from the interior area, wherein the generally thin walled deflection shields are spaced slightly apart so as to form a gap and to allow a portion of the second profile to enter into the interior area formed by the general c-shape section, and wherein the two generally thin walled deflection shields extend generally perpendicular from a respective one of the outer ends of the two extensions when the first and second profiles are not releasably engaged to each other, the two generally thin walled deflection shields being generally coplanar with each other when the first and second profiles are not releasably engaged to each other, wherein the thickness of the gap is less than the thickness of the general c-shape section and wherein the thickness of the two generally thin walled deflection shields is substantially less than the thickness of the general c-shape section.
