Abstract
A device to be incorporated in a container for valuables comprises a first reservoir (3) containing a liquid coloring material or a noxious gas, preferably an ink, a second reservoir (14) containing a pressurized gas, and an actuator (13) connected to a detection system. The pressurized gas is liberated if required by the detection system. The first reservoir (3) is able to collapse under the sudden increase in pressure resulting from the release of the gas. The content of the first reservoir is ejected through a retaining valve and an elongated perforated pipe (10) for spraying the valuables.
