Abstract
The invention relates to a method for retrieving a shut state and/or a location of a closable container as well as closable containers, wherein a transition between an open position and a closed position is achieved by a relative movement at least of a first container part with respect to a second container part, wherein the container has at least one RFID chip having a connected near field antenna and a far field antenna and the RFID chip having the connected near field antenna is arranged at the first or at the second container part and the far field antenna is arranged at the other one of the first and second container part, respectively, and the near field antenna, which is connected to the RFID chip, is arranged, as compared to the far field antenna, such that, in the closed position of the container, a noncontact electromagnetic coupling takes place between the near field antenna and the far field antenna. In the context of the method, due to the interaction of a sending unit and a receiving unit, a response signal can by generated by means of the RFID chip and can be transmitted, the range of said response signal depending on the shut position of the container.
