Abstract

An RFID enabled waste/recycling container includes a molded plastic body; and a case containing an RFID device. The case includes a front surface and a rear surface defining a wedge-shape. The case is in-molded with the plastic body such that a substantial portion of the front surface and the rear surface are exposed. In another embodiment, the case is also designed to snap-fit to a waste/recycling container.

Claims

1. An RFID enabled waste/recycling container comprising:

a molded plastic container body; and

a case containing an RFID device, said case having a front surface and a rear surface defining a wedge-shape, said case molded to said plastic container body such that at least a substantial portion of both of said front surface and said rear surface are exposed.

2. The waste/recycling container of claim 1 wherein the container includes a rim, and wherein said plastic portion is a rib extending from said rim.

3. The waste/recycling container of claim 1 wherein said case includes first and second longitudinal ends, and first and second protrusions extending from said first and second longitudinal ends respectively.

5. The waste/recycling container of claim 1 wherein said RFID device is an RFID label, said label including a substrate, an antenna attached to said substrate, and an RFID chip in electrical connection with said antenna.

6. The waste/recycling container of claim 1 wherein said case includes a peripheral portion and a central portion, said central portion forming a majority of said front and rear surfaces of said case, said first and second longitudinal ends and a portion of said front and rear surfaces, said plastic portion molded to said peripheral portion, said plastic portion not molded to said central portion.

7. The waste/recycling container of claim 6 wherein said central portion of each of said front and rear surface protrudes outwardly from said front and rear surfaces.

8. The waste/recycling container of claim 7 wherein said central portion protrudes outwardly from said front and rear surfaces to define said wedge shape.

4. The waste/recycling container of claim 4 including a second said case, and first and second ribs extending from the container, each said rib defining a hole, said first and second protrusions on said second case snap-fitted into said holes of said first and second ribs respectively.

9. An RFID enabled waste/recycling container comprising:

a container body including first and second attachment portions;

a case including an interior and an exterior, said interior defining a cavity, said exterior having first and second attachment portions extending from said case, said first case attachment portion interfitted with said first container attachment portion, and said second case attachment portion interfitted with said second container attachment portion; and

an RFID device within said cavity within said case.

10. The RFID enabled waste/recycling container of claim 9 wherein said case includes first and second longitudinal ends, said first protrusion extending from said first longitudinal end, said second protrusion extending from said second longitudinal end.

11. The RFID enabled waste/recycling container of claim 10 wherein said case includes a front surface and a rear surface that combine to form a wedge shape.

12. The waste/recycling container of claim 10 wherein said case defines a first hole and a second hole, said holes each located proximate one of said longitudinal ends and extending through said front and rear surfaces.

13. The waste/recycling container of claim 9 wherein said container includes a sidewall, and a rim extending outwardly from said sidewall, said case first and second ribs extending from said rim.

14. The waste/recycling container of claim 9 wherein said first and second protrusions each include a curved surface.

15. The waste/recycling container of claim 9 including a second said case molded to said container.

16. A method of manufacturing a waste/recycling container with an RFID device, comprising:

placing an RFID device in a case, said case having a front surface and a rear surface that combine to form a wedge shape;

providing a mold having a mold surface, and a pocket defined in said mold surface, said pocket having two walls that converge to form a wedge shape corresponding to said wedge shape of said case;

placing said case in said pocket, such that a substantial portion of said front and rear surfaces of said case engage said converging walls of said pocket and other portions of said case are exposed;

injecting a thermoplastic onto said mold surface and over said pocket, said thermoplastic contacting only said exposed portions of said case;

curing said thermoplastic; and

removing said container including said case from said mold.

17. A method of molding a container comprising:

placing an RFID device within a case;

placing the case in a mold with a substantial majority of the case surface in substantial direct contact with the mold wall;

injection molding plastic into the mold;

allowing the plastic to solidify; and

removing the container from the mold.

18. An RFID assembly comprising:

a case having an interior defining a cavity, and an exterior including a front surface and a rear surface, said first and second surfaces converging such that said portions of said front and rear surfaces form a wedge shape; and

and RFID device disposed within said cavity within said case.

19. The RFID assembly of claim 18 wherein said front and rear surfaces each include a peripheral portion and a central portion, said central portion of said front surface defining said first plane, said central portion of said rear surface defining said second plane.

20. The RFID assembly of claim 18 including first and second longitudinal ends, each said end including a protrusion for snap-fitting said case to an item.

21. The RFID assembly of claim 20 including at least one fastener hole extending through said case for extending a fastener through said hole to attach said case to an item.

22. An RFID assembly comprising:

a case having an interior defining an opening, and an exterior including a first end, a second end, a first protrusion extending from said first end and a second protrusion extending from said second end; and

an RFID device within said opening of said case.

23. The RFID assembly of claim 22 wherein at least a portion of said case has a wedge shape.
