Abstract
Disclosed is a sealing detection mechanism for detecting sealing of a closure fastened to a container having a top open end. The sealing detection mechanism includes a RFID tag mounted at a selected position of the closure, at least one operable tear portion formed at the closure, and at least one conductive unit electrically connected to the RFID tag and extended from the RFID tag to the closure to form a conductive circuit loop across the operable tear portion of the closure. A sealing guarantee device mounted is selectively mounted between the top open end of the container and the closure, which includes an upper portion, a lower portion, and a middle portion connected between the upper portion and the lower portion. The lower portion of the sealing guarantee device is provided with an annular flange protruding downward from the lower portion and a hollow portion between the lower portion and the flange.
