Abstract

A device, the purpose of which is to prevent theft from stores by rendering the stolen object unusable for the thief. There is a radio loop transmitting a directed and coded signal which in turn is received by a receiver in the device. The receiver decodes the signal and transforms it to a start impulse for the release mechanism in the device. Hereby a glass or plastic ampule in the device is destroyed and its content, a fluid, spreads under pressure through holes in the device and renders the theft-protected item unusable.
