Abstract

The invention relates to an external package, particularly one with a conductive coating and in whose surroundings an RFID tag is used. The conductive area of the electrically conductive layer is interrupted by a structure.

Claims

1. An external package for a product having an electric component, comprising:

at least one support and an electrically conductive layer coupled to the support, where the external package comprises one of a paper or a polymer film forming the support;

the electrically conductive layer having an electrically conductive area, the layer comprising a structure and/or a coating arranged to reduce the electrical shielding otherwise exhibited by the conductive area in the surroundings of the external package such that electromagnetic radiation penetrates through the electrically conductive layer, the use of the electric component which delivers or receives information externally through the external package and/or whose power supply is fed through the external package thereby being not adversely affected or thereby is adversely affected only to an extent such that the component remains is still operable, the structure for dividing the conductive area of the electrically conductive layer into at least two areas.

2. The external package as claimed in claim 1, wherein the structure comprises a recess in the conductive area of the electrically conductive layer.

3. The external package as claimed in claim 1 wherein the structure comprises at least two recesses

4. The external package as claimed in claim 1 wherein the coating for reducing the shielding comprises a metal layer with a maximum thickness of 1 μ

m with further layers for completing the external package.

6. The external package as claimed in claim 1 wherein the structure and/or portions of the structure form electric components, comprising at least one of an antenna, a capacitor, a conductor track, and a diode or portions thereof.

7. The external package as claimed in claim 1 wherein the structure at least partly exhibits not only its technical effect of reducing electrical shielding, but also a visual effect, comprising reproducing at least one of an image, a security feature, a lettering, a miscellaneous visual feature and/or a logo.

8. The external package as claimed in claim 1 wherein the structure is arranged to interrupts the electrically conductive area of the electrically conductive layer at least once.

9. The external package as claimed in claim 8 wherein the electrical component includes a coil adjacent to the conductive layer, the interruption dividing the conductive area in at least the area adjacent to the coil into two halves.

10. The external package as claimed in claim 9 wherein the coil has a center, the structure being arranged opposite the center of the coil.

11. The external package as claimed in claim 1 wherein the surface of the external package is arranged to exhibits an image.

12. The external package as claimed in claim 1 arranged for use in at least one of for a cigarette package, a grocery package, a medicine package, a radio, a remote control or a microwave oven.

14. The external package as claimed in claim 1 wherein the support has a thickness of less than or equal to about 50 μ

m.

15. The external package as claimed in claim 1 wherein the electrically conductive layer has a thickness of less than or equal to about 50 μ

m.

16. The external package as claimed in claim 1 wherein the structure has a width and a length, the width having a value of up to about 500 μ

m.

17. The external package as claimed in claim 1 wherein the external package has a side of a given extent, the structure extending over more than half of the given extent of the side of the external package.

5. (canceled)

13. A process for manufacturing an external package for an item comprising patterning an electrically conductive layer or coating employing dry phase patterning of a metallized layer to thereby form part of the package, which part permits electromagnetic radiation to penetrate there through.
