Abstract

An apparatus and method for manufacturing plastic containers having RFID tags embedded therein is disclosed. The bottles are manufactured using a blow-molding technique wherein an in-mold film having an RFID tag embedded therein is positioned or placed against the parison immediately prior to the blow mold being closed and the pressurized air being used to inflate the parison. The resulting container thus has an RFID tag fused thereto to allow for tracking and tracing of the container after manufacture, as well as providing a mechanism by which the authenticity of the bottle can be verified.

Claims

1. A method of molding a container having an RFID tag therein, comprising the steps of:

molding a heated parison;

positioning the heated parison between halves of a mold having a cavity in the form of the desired container;

placing an in-mold film in contact with the heated parison, the in-mold film having the RFID tag incorporated therein;

forcing the mold halves together;

inflating the heated parison to form the container; and

removing the container from the mold with the in-mold film and RFID tag fused thereto.

2. The method of claim 1, wherein the step of molding the parison is performed by injection molding the heated parison around a mandrel.

3. The method of claim 1, wherein the step of placing an in-mold film in contact with the heated parison does not include adhesives.

4. The method of claim 1, wherein the in-mold film placed in contact with the heated parison includes at least four layers.

5. The method of claim 1, wherein the in-mold film placed in contact with the heated parison includes a urethane layer.

6. The method of claim 1, wherein the in-mold film placed in contact with the heated parison includes a security layer.

7. The method of claim 1, wherein the in-mold film placed in contact with the heated parison includes a graphics layer.

8. The method of claim 1, wherein the in-mold film placed in contact with the heated parison includes a fusion layer.

9. The method of claim 1, wherein the step of forcing the mold halves together is performed by hydraulic cylinders.

10. A method of molding a container having an RFID tag therein, comprising the steps of:

injection molding a heated parison around a mandrel;

positioning the heated parison and mandrel between halves of a mold having a cavity in the form of the desired container;

placing an in-mold film into direct contact with the heated parison, the in-mold film having at least four layers and the RFID tag incorporated therein;

forcing the mold halves together;

inflating the heated parison to form the container; and

removing the container from the mold with the in-mold film and RFID tag fused thereto.

11. The method of claim 10, wherein the step of placing an in-mold film into contact with the heated parison does not include adhesives.

12. The method of claim 10, wherein the in-mold film placed into contact with the heated parison includes a urethane layer.

13. The method of claim 10, wherein the in-mold film placed into contact with the heated parison includes a security layer.

14. The method of claim 10, wherein the in-mold film placed into contact with the heated parison includes a graphics layer.

15. The method of claim 10, wherein the in-mold film placed into contact with the heated parison includes a fusion layer.

16. The method of claim 10, wherein the step of forcing the mold halves together is performed by hydraulic cylinders.

17. An apparatus for molding a container having an RFID tag therein, comprising:

a turn-table having a plurality of mandrels outwardly extending therefrom, the turn-table being rotatable in increments such that the mandrels sequentially move along a linear pathway; and

a plurality of stations positioned along the pathway such that each station is in close proximity to at least one mandrel at any one time, the plurality of stations including at least a first station having a parison mold for injection molding a parison onto the mandrel, a second station for positioning an in-mold film having the RFID tag therein directly onto the parison and having a blow mold for blow-molding the container, a third station for removing the container from the mandrel, and a fourth station for conditioning and preparing the mandrel for molding a new parison thereon.

18. The apparatus of claim 17, wherein the turn-table rotates in increments of 90 degrees.

19. The apparatus of claim 17, wherein the second station further includes hydraulic cylinders for sealing the blow mold.

20. The apparatus of claim 17, wherein the first and second stations are maintained at relatively elevated temperatures
