IMPROVEMENTS RELATING TO TAMPER PROOF CLOSURES |
摘要 |
A tamper proof closure (1) has a plurality of magnetic strips (7) attached thereto which are arranged to be broken if the closure is opened. The broken magnetic strips have a different magnetic characteristic as compared to when they are intact and this can be sensed with a Hall effect or other sensor. The tamper proof closure enables the condition of article closures such as the screw caps of liquor bottles to be remotely monitored.
