Electronic label
Electronic labels consist of an electronic chip ( 4 ) and an antenna ( 3 ) assembled on a flexible support ( 2 ). The electronic chip ( 4 ) needs a rigid zone in order to not be damaged. This is why it is generally covered with a resin that makes this rigid region bigger. In order to reduce this zone the resin that covers the chip is suppressed and replaced with a protection ( 5 ) ensured by a rigid element added to the flexible support ( 2 ).
1. A flexible electronic label comprising at least a flexible support, an antenna, and an electronic chip, said chip being rigidly assembled with said flexible support and connected to the antenna, a rigid non-removable element disposed on at least one face of the support and above and/or underneath the chip, said rigid non-removable element being disposed in such a way that said element has a larger extent than an extent occupied by the chip alone and that said element is fixed on an area of said flexible support surrounding said chip.
2. The electronic label according to claim 1 , wherein the rigid non-removable element is a part of an element that serves as a closing element or fixation of the label.
3. The electronic label according to claim 1 , wherein the rigid non-removable element is an independent element serving as protection for the chip.
4. The electronic label according to claim 3 , wherein the independent element is assembled on the flexible support by gluing, welding, or by engagement.
5. The electronic label according to claim 1 , wherein at least one conductive wire is displayed along all a length of said label and whose interruption causes a cessation of functioning of said label.
6. The electronic label according to claim 5 , the at least one conductive wire is a part of the antenna.
7. The electronic label according to claim 5 , the at least one conductive wire is linked by two ends of the at least one conductive wire to the electronic chip.
8. The electronic label according to claim 5 , the at least one conductive wire crosses a separation zone with reduced solidity.
9. The electronic label according to claim 1 , wherein the rigid element has means to produce a destruction of the chip and/or the antenna during the separation of the said rigid non-removable element from the flexible support.
10. The electronic label according to claim 9 , the means comprise a glue placed between the chip and the rigid non-removable element, an adhesive power of the glue is greater than that of a binding agent placed between the chip and the flexible support.
11. The electronic label according to claim 9 , wherein the flexible support has a least two orifices between which passes at least one conductor of the antenna, at least two spigots that are connected to the rigid non-removable element and that cross said orifices, said spigots being widened at spigot ends either by adding a piece or by deformation.
12. The electronic label according to claim 1 , wherein a space is provided between the inner face of the rigid non-removable element and the chip.
13. The electronic label according to claim 12 , wherein the space between the inner face of the rigid non-removable element and the chip is filled with an epoxy resin filling material.
14. The electronic label according to claim 12 , additionally comprising a silicone filling material in the space between the inner face of the rigid non-removable element and the chip.
