Patent ID: 7646306

Claim:
A transponder for the emission and reception of radio frequency signals comprising, a chip and a coil reel, a plastic film covering, said chip and said coil reel, said transponder thus covered, being housed between male and female portions of a capsule, said female portion comprising a compact base connected to an equally compact side forming a smooth end rim, the internal wall of said compact side has an edge with a configuration comprising a small straight path, distal from said compact base, followed by a “V”, shape indentation followed by a retracted bottom housing which has its width limited by a ring wall, said ring wall extends up about the vertex of said “V” indentation, with said ring wall having a bevel on the side of the male portion and rounded edge on the other side; the bottom of said compact base is located at a level above the retracted bottom; the male portion comprises a compact top whose diameter is substantially compatible with the straight path of the female portion, with said top comprising an attachment portion, comprising a correspondence straight path followed by a “V”-shaped projection which is coupled and fits under relative pressure to the “V” shaped indentation of the female portion, while an equally ring-shaped rim is settled over the retracted bottom, so to be restrained by the ring wall; said male and female portions become fitted between them under considerable pressure; a chamber is created between the bottom of the compact base and the maximum height of the ring wall, coinciding with the bottom of the compact top, inside which the transponder is housed, with a diameter adjustment existing in said chamber very near to the internal diameter of the ring wall.
