Abstract

A sealing cap with an anti-counterfeit and identification capability comprises a cap body, an identification chip with a signal emitting device generating an identification signal, and a destructive device, characterized in that the cap body is electrically connected with the signal generating device and serves as an antenna of a relatively large area and in that the destructive device after dismounting of the cap destroys the capability to emit radiation and thus prevents said identifying chip from being dismounted and reused.

Claims

1. An anti-counterfeit sealing cap with identification capability, comprising:

a cap body, at least partially made of electrically conducting material, with an exterior surface thereof being a receiving and transmitting antenna;

a semiconductor identifying chip, attached on an inner side of said cap body, storing identification data, generating an identifying signal according to said identification data and being electrically connected with said cap body, so that said cap body radiates said generated identifying signal; and

a destructing device, preventing said identifying chip from being dismounted and reused;

wherein said cap body exterior surface radiates said identifying signal generated by said identifying chip, and wherein a destructing device prevents said identifying chip from being dismounted and reused.

2. The anti-counterfeit sealing cap with identification capability according to claim 1, wherein said cap body is made of electrically conducting material.

3. The anti-counterfeit sealing cap with identification capability according to claim 1, wherein said cap body is made of electrically non-conducting material, having a surface covered by an antenna which is made of electrically conducting material.

4. The anti-counterfeit sealing cap with identification capability according to claim 1, wherein said destructing device, upon opening of said cap body, physically destroys electrical connections of said identifying chip, so that emission of said identifying signal is terminated.

5. An anti-counterfeit sealing cap with identification capability, comprising:

a cap body, at least partially made of electrically conducting material, working as a receiving and transmitting antenna;

a semiconductor identifying chip, attached on an inner side of said cap body, storing identification data, generating an identifying signal according to said identification data and being electrically connected with said cap body, so that said cap body radiates said generated identifying signal; and

further comprising a destructing device which, upon opening of said cap body physically destroys said identifying chip, so that emission of said identifying signal is disabled;

wherein said cap body radiates said identifying signal generated by said identifying chip and where a destructing device prevents said identifying chip from being dismounted and reused; and

further

wherein said destructing device has a ring, which is separate from said cap body, and at least one connecting element connecting said ring and said cap body, so that, upon opening of said cap body, said identifying chip or said connectors are broken, disabling emission of said identifying signal.

6. The anti-counterfeit sealing cap with identification capability according to claim 5, wherein said destructing device has a plug, which is separate from said cap body, with at least one part of said identifying chip being connected with said plug, so that, upon opening of said cap body, said identifying chip or said connectors are broken, disabling emission of said identifying signal.

7. The anti-counterfeit sealing cap with identification capability according to claim 5, wherein said destructing device has a plug, which is separate from said cap body, with at least one of said connectors connecting said identifying chip and said plug, so that, upon opening of said cap body, said connectors are broken, disabling emission of said identifying signal.
