Method for incorporating an anti-counterfeiting device into a multi-walled container and the multi-walled container containing such device
View Patent ↗A method of incorporating an anti-counterfeiting device into a multi-walled container is provided. The multi-walled container includes an inner wall having an outer surface, an outer wall adjacent to the inner wall, and an anti-counterfeiting device sandwiched between the inner and outer walls. The method includes forming the inner wall from a polymeric composition, adhering the anti-counterfeiting device to the outer surface of the inner wall either during, or after formation of the inner wall, and then over molding the outer wall about the inner wall to form the multi-walled container. Suitable anti-counterfeiting devices for incorporation into the multi-walled container include RFID, printed or foil antennae, conductive inks, metal spheres, and x-ray readable foils.
1. A method for incorporating an anti-counterfeiting device into a molded multi-walled container wherein the multi-walled container comprises an inner sleeve having an outer surface, and an outer wall surrounding the inner sleeve, the method comprising the steps of:
(a) inserting an inner sleeve composition within a mold to form the inner sleeve of the container;
(b) adhering an anti-counterfeiting device to the outer surface of the inner sleeve;
(c) injection molding an outer wall composition over the inner sleeve and the anti-counterfeiting device to form the outer wall of the container and sandwich the anti-counterfeiting device between the inner sleeve and the outer wall of the container.
2. The method of claim 1 , wherein the anti-counterfeiting device is inserted into the mold prior to inserting the inner sleeve composition and the inner sleeve is injection molded so that the anti-counterfeiting device adheres to the outer surface of the inner sleeve.
3. The method of claim 1 , wherein the inner sleeve composition is injection molded to form the inner sleeve of the container and the anti-counterfeiting device is applied to the outer surface of the inner sleeve prior to or after removing the inner sleeve from the mold.
4. The method of claim 1 , wherein the anti-counterfeiting device comprises a label and a substrate material, and the substrate material is comprised of a polymeric material that is compatible with the inner sleeve composition.
5. The method of claim 1 , wherein the inner sleeve composition is extruded into a film and the film is cut and formed into a free-standing tubular structure which is inserted into the mold to form the inner sleeve of the container.
6. The method of claim 1 , wherein the anti-counterfeiting device is an antenna.
7. The method of claim 6 , wherein the antenna is printed using conductive ink.
8. The method of claim 6 , wherein the antenna is formed from a foil material.
9. The method of claim 8 , wherein the foil material is perforated or shaped.
10. The method of claim 6 , wherein the antenna is placed on a label.
11. The method of claim 1 , wherein the anti-counterfeiting device comprises a RFID.
12. The method of claim 1 , wherein the anti-counterfeiting device comprises a label printed with conductive ink.
13. The method of claim 1 , wherein the anti-counterfeiting device comprises conductive metal spheres incorporated into a carrier substrate.
14. The method of claim 1 , wherein the anti-counterfeiting device comprises a foil readable by x-ray.
15. The method of claim 1 , wherein a label comprising a tuner is applied to the outer wall of the container during or after the wall is molded.
16. The method of claim 15 , wherein the label amplifies or cancels a signal from the anti-counterfeiting device.
17. A molded multi-walled container including an anti-counterfeiting device comprising:
a container outer wall formed from a molded polymeric material and defining a storage space in which an item can be stored;
a container inner sleeve provided within the storage space defined by the container outer wall, said container inner sleeve being formed from a molded or extruded polymeric composition that is inserted within a mold and having an outer surface adjacent the container outer wall, the molded polymeric material of the container outer wall being injection molded over the container inner sleeve; and
an anti-counterfeiting device adhered to the outer surface of the inner sleeve so that the anti-counterfeiting device is sandwiched between the inner sleeve and the outer wall.
18. The container of claim 17 , wherein the anti-counterfeiting device comprises a label and a substrate material, and the substrate material is comprised of a polymeric material that is compatible with the inner sleeve polymeric composition.
19. The container of claim 17 , wherein the anti-counterfeiting device is an antenna.
20. The antenna of claim 19 , wherein the antenna is printed using conductive ink.
21. The antenna of claim 19 , wherein the antenna is formed from a foil material.
22. The antenna of claim 21 , wherein the foil material is perforated or shaped.
23. The antenna of claim 19 , wherein the antenna is placed on a label.
24. The container of claim 17 , wherein the anti-counterfeiting device comprises a RFID.
25. The container of claim 17 , wherein the anti-counterfeiting device comprises a label printed with conductive ink.
26. The container of claim 17 , wherein the anti-counterfeiting device comprises conductive metal spheres incorporated into a carrier substrate.
27. The container of claim 17 , wherein the anti-counterfeiting device comprises a foil readable by x-ray.
28. The container of claim 17 , wherein a label comprising a tuner is applied to the outer wall of the container.
29. The container of claim 28 , wherein the label amplifies or cancels a signal from the anti-counterfeiting device.
30. A molded multi-walled container having a RFID inlay, comprising:
a container outer wall formed from a molded polymeric material and defining a storage space;
a container inner wall provided within the storage space, the container inner wall being formed from a molded or extruded polymeric composition that is inserted within a mold and having an outer surface adjacent to the container outer wall, the molded polymeric material of the container outer wall being injection molded over the container inner wall; and
a RFID inlay housed between the inner wall and the outer wall.
31. The container of claim 30 , wherein the RFID inlay is adhered to the outer surface of the container inner wall.
