Abstract:
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.
