Integrally, extrusion blow molded container, label and RFID tag
An improved method for molding a plastic container within a mold including an RFID tag to generate a container which leaves a mold having an RFID tag bonded between the container and a label. This method provides for an improved integrally, extrusion blow molded container, label and RFID tag combination.
1. A combination of a mold and plastic container comprising:
at least two mold portions engaged to form an interior surface having a temperature of at least 420° F.;
a label and an electrical signal generator, the generator being fabricated from materials to retain its signal generating functionality after being heated over 420° F., the generator being fabricated to be compliable with the interior surface of the mold and the generator having first and second sides coated with a heat activated adhesive, the label being located adjacent to the interior surface, and separating the generator from the internal surface; and
a parison having at least an interior layer defining an interior and an exterior layer, the interior being pressurized to expand the parison to force the exterior layer into contact with the generator, label and interior surface to reshape the parison into a plastic container located within the mold portions, the plastic container including a threaded neck portion integrally molded with a vessel portion.
2. The combination of claim 1 , wherein the generator is an RFID tag.
3. The combination of claim 2 , wherein the RFID tag includes at least an IC chip coupled to an antenna, the chip and the antenna being enclosed by 2 sheets of material such that the signal generating functionality of the RFID tag is maintained after being heated over 420° F.
4. The combination of claim 1 , wherein the parison is at least 420° F.
5. The combination of claim 1 , wherein the interior layer is used for a barrier layer resin EVOH or PP if barrier not required use HDPE and the exterior layer is HDPE.
6. The combination of claim 2 , wherein the activatable adhesive is used to bond 2 dissimilar materials together to create a barrier layer, or if barrier is not required HDPE will be used for each layer.
7. A plastic container comprising:
a label and an electrical signal generator enclosed by 2 sheets of material to retain its signal generating functionality after being heated over 420° F., at least a portion of each the generator being fabricated to be compliable with the interior surface of a mold; and
a hollow plastic container fabricated from at least an interior layer of plastic and an exterior layer of plastic, the container including a neck portion integrally molded with a vessel portion, one of the sheets being bonded to the vessel portion by an heat activated adhesive and the other of the sheets being bonded to the label by a heat activated adhesive.
8. The container of claim 7 , wherein the generator is an RFID tag.
9. The container of claim 8 , wherein the RFID tag includes at least an IC chip coupled to an antenna, the chip and the antenna being enclosed by the 2 sheets of material such that the signal generating functionality of the RFID tag is maintained after being heated over 420° F.
10. The container of claim 9 , wherein one of the sheets is a ceramic material.
11. The container of claim 9 , wherein at least one of the sheets is a thermoset plastic material.
12. The container of claim 11 , wherein the interior layer is HDPE or a barrier resin if required and the exterior layer is HDPE.
13. The container of claim 12 , wherein the activated adhesive is HDPE or adhesive resin if required which has been heated to 420° F. then cooled to 25° C.
