I and 2; FIG. 4 is a fragmentary sectional view taken substantially along the line 4-4 in ' FIG. 3; FIG. 5 is a perspective view of the seal disk in the package of FIGS. 1-2; FIGS. 6 and 7 arc fragmentary sectional views taken substantially along the respective lines 6-6 and 7-7 in FIG, 5; and FIG. 8 is a fragmentary sectional view similar to those of FIGS, 4 and 6 but illustrating a modification to the embodiment of FIGS, 1-7. Detailed Decription of Preferred Embodiment FIGS. 1-2 illustrate a package 10 in accordance with an exemplary embodiment of the present disclosure. Package 10 includes a container 12 having a neck fmish 14. Neck finish 14 is illustrated as being cylindrical in the exemplary embodiment of the disclosure, but could be oval or of any other suitable geometruy. Closure 16 includes a plastic she!) with a skin having internal threads or beads 20 for engagement with external threads or beads 22 onneck finish 14 to secure the closure to the container. Skirt 18 preferably is cylindrical, and may be a peripheral skirt as illustrated or an inner skirt within an outer skirt of suitable geometry such as can be of any suitable construction, such as molded plastic or glass. A seal disk 24 (FIGS. 1-2 and 5-7) includes at least an electrically conductive layer 26 deposited or otherwise disposed on a plastic layer or substrate 2S. Seal disk 34, including conductive layer 26 and plastic substrate 28, preferably is of circular geometry corresponding to the preferred cylindrical geometry of container neck finish 14. Plastic substrate 28 preferably is of a material, such as polyethylene tcrephthalate CPET), a type of polyethylene (e.g.,LDPE, MDPEorHDPE) or other suitable plastic, that can be induction bonded to the end of container neck finish 14. Conductive layer 26, which may be of alumuium or electrically conductive paint construction, preferably includes a circumfercnti ally continuous outer peripheral ring 30 that overlies the periphery of substrate 28, and an inner portion that is etched or otherwise formed on substrate 28 in an interrupted pattern. In the exemplary embodiment illustrated in the drawings, the inner portion of conductive layer 26 includes a ring-shaped inner periphery 32 and a plurality of radial spokes 34 that interconnect inner periphery 32 with outer periphery 30. Other inlemipted geometries can be employed. An RFID assembly 36 (FIGS. 1-4) is captured between seal disk 24 and the base wall of closure 16. RFID assembly 36 includes a substrate 3 8, preferably of plastic construction, and an rf antenna 40 deposited or otherwise disposed on substra«3S. Antenna 40 can be etched, painted or otherwise formed in any suitable antenna geometry. An RFID microcircuit or tag 42 is disposed on antenna layer 40 and electrically Connected to the antenna, which may be of aluminum constmction for example, Thus, lag 42 can be interrogated from outside of the container through antenna 40 to obtain information from tag 42 lo confirm genuineness of the package and/or to identify the product within the package such as forpricing or inventory control purposes. The structures of RFID tag 42, antenna 40 and the external circuitry for interrogating 4 ths RFID tag through the antenna can be of any suitable type known in the art. The interupted center portion of seal disk conductive layer 26 helps reduce or eliminate interference, which might otherwise be caused by seal disk conductive layer 26, in communications between RFID assembly 36 and the external interrogation circuitry. A liner disk -14 (FIGS. 1-2) optionally may be disposed between seal disk 24 and RFID assembly 36 within closure 16. Liner disk 44 may be of any suitable construction, such as cellulose, to function as a liner to seal the package after seal disk 24 has been removed. Liner disk 44 may be retained within closure 16 by means of an internal bead 46 (FIG. 1) on the closure skin. Bead 46 can be circumferentially continuous or segmented. Liner disk 44, in addition to functioning as a package seal after seal disk 24 has been removed, also captures RFID assembly 36 within closure 16. RFID assembly 36 can be adhered to the adjacent face of liner disk 14 to facilitate placement of the RFID assembly within the closure. After placement of product 4S within container 12, seal disk 24, RFID assembly 36 and closure 16, preferably including liner disk 44, sre placed over the container neck finish. Seal disk 24 is then induction bonded or otherwisesecured to the end of container neck finish 14. Induction bonding is facilitated by the circumferentially continuous outer peripheral ring 30 of conductive layer 26 CFIGS. 5 and 6). The closed package, including RFED assembley 36, can be interrogated to confion genuineness of product 48 within the package or to identify the package and/or product such as by product type, lot number or the like. To open the package, closure 16 is removed from the package, preferably simultaneously removing iiner disk 44 and RFID assembly 36, and seat disk 24 is ruptured to obtain access to the product within the package. Such rupturing of seal disk 24 provides a visual indication that the package has been opened, but does not impair communications with RFID assembly 36. no. 8 illustratcs a disk assembly 50 that includes RFID assembly 36 bonded to the upper surface of liner disk 44, and liner disk 44 bonded by an adhesion layer 52 at least to the outer peripheral ring 30 of seal disk 24. Adhesion layer 52 preferably is of a material, such as wax, [hat evaporates upon application of electrica! energy to ring 30. Thus, induction bonding of seal disk 24 to the container neck finish simultaneously functions in this embodiment to separate liner disk 44 and RFID assembly 36 from seal disk 24 so that the liner disk and RFID assembly thereafter are removable with the closure while leaving seal disk 24 in place on the container neck finish. This embodiment has the advantage that disk assembly 50, including RFID assembly 36, liner disk 44 and seal disk 24, can be applied in one step and liner disk 44 separated from seal disk 24 during the induction bonding operation. In the embodiment of FIGS. 1-7, seal disk 24 can be bonded to the container neck finish prior to assembly of closure 16 (with or without liner disk 36) to the container neck finish. There thus have been disclosed a package and a closure, with an RFID tag and with a seal disk constructed to reduce or eliminate interference in communications between the RFID assembly and external interrogation circuitry', which fully satisfy all of the objects and aims previously set forth. The disclosure has been presented in conjunction with several exemplary embodiments, and other modifications and variations have been discussed.
