Abstract

The present invention relates to an RFID device that is intended to be used in connection with direct or indirect packaging of consumer food products, such as with the use of food trays, totes and other transport packaging for perishable items. The RFID device may include a RFID inlay assembly that has been encased in a laminate that is safe for use with food products.

First claim

What is claimed is:

1 . A consumer food tray for transporting consumer food goods, comprising:
a tray having a base with first and second sides, said base having end walls encircling said baseand extending generally upwardly from said base; a consumer food good; an RFID device, said RFID device comprising an RFID inlay, said inlay having a chip encoded with product information and an antenna bonded to said chip, said RFID device including first and second GRAS substrates each of said first and second substrates having first and second surfaces, said inlay is disposed between said first surface of said first substrate and said second surface of said second substrate; wherein said RFID device is in contact with said consumer food good; and wherein said second GRAS substrate has an area greater than each of an area of said RFID inlay and an area of said first GRAS substrate.

2 . A consumer food tray as recited in claim 1 , wherein said RFID inlay includes a strap connecting said chip to said antenna.

3 . A consumer food tray as recited in claim 1 , wherein said second GRAS substrate has an area greater than each of an area of said RFID inlay and an area of said first GRAS substrate.

4 . A consumer food tray as recited in claim 7 , wherein said RFID device is adhered to said consumer food tray by a GRAS adhesive.

5 . A consumer food tray as recited in claim 7 , wherein said RFID inlay includes a first substrate and a second substrate between which said chip and said antenna are disposed.

6 . A consumer food tray as recited in claim 9 , wherein said second GRAS substrate is permanently sealed to said RFID inlay.

7 . A method for producing a GRAS RFID device in connection with a food carrier, comprising the steps of:
providing an RFID inlay manufactured using a strap, the inlay having an antenna; placing said RFID inlay on a first GRAS substrate; covering said RFID inlay and said first GRAS substrate with a second GRAS substrate; adhering said first and second GRAS substrates together with said RFID inlay containeds there between to form a laminated assembly; and affixing said laminated assembly to a food carrier.

8 . A method as recited in claim 7 , including the further step of encoding the RFID inlay after the step of providing an RFID inlay.

9 . A method as recited in claim 7 , including the further step of testing the RFID inlay after the step of encoding the RFID inlay.

10 . A method as recited in claim 19 , including the further step of printing on said second GRAS substrate after the step of securing the laminated construction together.

11 . A method as recited in claim 19 , including the further step of reducing, covering or eliminating a portion of the antenna.

12 . An RFID device for use in direct or indirect food packaging applications, comprising;
an RFID inlay having a chip encoded with product information and an antenna bonded to said chip; first and second substrates, each of said substrates having first and second surfaces, and first and second transversely extending edges and first and second longitudinally extending sides and each of said substrates being GRAS; wherein said RFID inlay is disposed between each of said first and second substrates and each of said first and second longitudinally extending sides and each of said first and second transversely extending edges are sealed to one another so as to create a sealed enclosure for said RFID inlay; and wherein said RFID inlay includes a strap connection from said chip to said antenna.
