An RFID sealing device for a bottle is disclosed, which provides information of production resumes, stock control, sale control and so like, where the information may be adapted for a computerized foods management system for the upstream manufacturer and the downstream sellers. Since the metal cap plays a part in the RFID sealing device, the RFID shall malfunction once the bottle cap has been turned or opened before sale, so that the present RFID sealing device plays a function of safety identifier to the bottled liquid or food in addition.

RFID sealing device for bottle

An inductor structure including a plurality of solenoids and at least one connecting line is provided. One of the solenoids serves as a core, and the remaining solenoids are sequentially wound around the core solenoid. Axes of the solenoids are substantially directed to the same direction. Each connecting line is correspondingly connected between ends of two adjacent solenoids to serially connect the solenoids.

Inductor structure

An antenna having a signal feeding structure, an antenna conductor coupled to the signal feeding structure and forming a slot in the antenna conductor. A closing portion capacitively closing the at least one slot at a mechanically open end of the slot.
