Abstract:
1. A sealing detection mechanism for detecting a condition of a seal of a closure fastened to a container having a top open end, said detection mechanism comprising: an RFID tag mounted at a selected position of the closure; at least one operable tear portion formed at the closure, the operable tear portion being provided with two inverted V-shaped notches at a bottom edge of the closure, a tear tab thereby being formed between two V-shaped notches; and at least one conductive unit electrically connected to the RFID tag and extended from the RFID tag to the closure to form a closed conductive circuit loop across the operable tear portion of the closure; wherein (1) when the closure is properly sealed on the top open end of the container, the conducting circuit loop forms a closed circuit and the RFID tag is operable to transmit a conductive code to an RFID reader; and (2) when the closure is not properly sealed or is, damaged, broken, or removed from the container, the conducting circuit loop forms an open circuit defining is in an open state, resulting from the fracture of the operable tear portion, and the RFID tag transmits an open-circuit code to the RFID reader.
