Closure having RFID and foil
View Patent ↗A closure comprising a top wall with an annular side wall depending there from. An induction foil is proximate an inner surface of the top wall and may have a ring or circular configuration. An RFID device is affixed or is integral with the closure a minimum distance from and/or orientation with the induction foil as to prevent damage to the RFID device during an induction sealing process and to reduce adverse operational effects of the RFID from the foil. The RFID may be active or passive and may be proximate or integral with the top wall or integral with the side wall of the closure. The RFID may be contained within a film wherein a portion of the film is inductively sealed to the closure.
1. A closure for use in an induction sealing process comprising:
a closure having a top wall;
an annular side wall depending from said top wall of said closure;
an induction sealing disc including an annular induction foil and a substantially circular sealing film combining to sealingly engage an opening of a container neck;
said annular induction foil proximate an inner surface of said top wall of said closure;
said substantially circular sealing film having an RFID device embedded therein, wherein said RFID device is centrally secured relative to each of said sealing film and said annular induction foil of said induction sealing disc, wherein said RFID device is positioned at a minimum distance of at least 0.2 inches from the interior radius of said annular induction foil so as to prevent damage to said RFID device during an induction sealing process and to reduce adverse operational effects of said RFID device from being too close to said annular induction foil after said induction sealing process; and
wherein said adverse operational effects include at least interference from being too close to said annular induction foil.
2. The closure of claim 1 wherein said sealing film has an outer edge portion adjacent said annular induction foil.
3. The closure of claim 2 wherein said outer edge portion of said sealing film is adjacent the interior radius of said annular induction foil whereby said RFID device is at least 0.2 inches away from said outer edge portion of said sealing film.
4. The closure of claim 2 wherein said annular induction foil having a top side and a bottom side, said top side of said annular induction foil secured against said inner surface of said closure top wall and said bottom side of said annular induction foil secured against said outer edge portion of said sealing film.
5. The closure of claim 2 wherein said annular induction foil having a top side and a bottom side, said top side secured against said outer edge portion of said sealing film and said bottom side secured against a rim surrounding the opening of the container neck, said sealing film secured against said inner surface of said top wall.
6. The closure of claim 2 wherein said annular induction foil having a top side and a bottom side, said top side secured directly to each of said outer edge portion of said sealing film and said inner surface of said top wall and said bottom side secured against a rim surrounding the opening of the container neck.
7. A closure comprising:
an induction sealing disc including a metallic annular induction foil and a film combining to sealingly engage an opening of a container neck;
said metallic annular induction foil having an inner radius; and
said film having a substantially circular configuration, said film containing an RFID fully embedded therein proximate the center of said film, wherein said RFID is spaced at a predefined distance from said inner radius of said annular induction foil, wherein said predefined distance is at least 0.2 inches so as to reduce reduction in performance of said RFID as a result of an induction sealing process and to reduce adverse interference of said RFID during operation from being too close to said annular induction foil.
8. The closure of claim 7 wherein said film is positioned below said metallic layer within said induction sealing disc.
9. The closure of claim 7 wherein said film is positioned on top of said metallic layer within said induction sealing disc.
