Closure and package with induction seal and RFID tag
First Claim
1. A package that includes a container having a neck finish, and a closure that includes:
- a plastic shell having a skirt externally secured to said neck finish,a seal disk that includes an electrically conductive layer on a plastic substrate,a periphery of said plastic substrate being sealingly secured to said neck finish, said electrically conductive layer including a circumferentially continuous outer periphery overlying said periphery of said plastic substrate and an inner portion within said outer periphery structured as an rf antenna,an RFID tag on said seal disk electrically connected at least to said inner portion of said electrically conductive layer, anda liner disk between said closure and said seal disk.

Abstract
A package includes a container having a neck finish, and a closure having a plastic shell with a skirt externally secured to the container neck finish. A seal disk includes a metal layer on a plastic substrate. The periphery of the plastic substrate is sealingly secured to the neck finish of the container. The metal layer includes a circumferentially continuous outer periphery overlying the periphery of the plastic substrate and an inner portion structured as an rf antenna. An RFID tag is electrically connected at least to the inner portion of the metal layer. A liner disk may be disposed between the closure and the seal disk separate from the seal disk. The closure skirt may have an internal bead to engage the periphery of the liner disk and lift the liner disk off of the neck finish upon removal of the closure from the container neck finish.

9. A seal disk for placement in a closure and container package, which includes:
-
a plastic substrate disk having a circular outer periphery, an electrically conductive layer on said plastic substrate disk having a circumferentially continuous outer periphery overlying said outer periphery of said plastic substrate disk and an inner portion within said outer periphery structured as an rf antenna, said outer periphery of said plastic substrate disk underlying said outer periphery of said electrically conductive layer being adapted to melt and to bond said seal disk to a container neck finish upon application of electrical energy to said outer periphery of said electrically conductive layer, an RFID tag on said seal disk electrically connected at least to said inner portion of said electrically conductive layer, and a liner disk secured at least to said outer periphery of said electrically conductive layer by an adhesive layer that is adapted to evaporate upon application of electrical energy to said outer periphery of said electrically conductive layer to separate said liner disk from said electrically conductive layer. - View Dependent Claims (13)
