Patent

CA 2331654

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.

L'invention se rapporte à une fermeture de sécurité (1) à laquelle sont fixées plusieurs bandes magnétiques (7) qui sont disposées de manière à être brisées lorsque la fermeture est ouverte. Les bandes magnétiques brisées possèdent une caractéristique magnétique différente de celle correspondant à leur état intact, ce qui permet de détecter l'ouverture au moyen d'un capteur à effet Hall ou autre. Cette fermeture de sécurité permet de surveiller à distance l'état de dispositifs de fermeture d'articles tels que des capsules à vis de bouteilles de liqueur.
