The security case (1) resists to all external attempts of breaching and is provided with a double envelope casing (2 and 3) of which one part (2) is depressurized, the other part (3) being filled with an indelible ink and a propulsing gas, and is provided with pressure switches (39) and temperature switches (54), the case being provided with a security system comprising the cartridges (11 and 12) which, when exploding, dispense their contents due to the shock of various strikers (32, 36, 37) arranged on the ramp (18), the explosion occuring upon an illicit opening or a forced opening. The unlocking of said security system is obtained by displacing two pushers (13) handled by the unlocking locks (9) which are all independent from each other, and operating either to the left or to the right, with zero return. The locks are provided with racks (45) and strikers (17) which, in the case of an incorrect opening, do not displace a pusher (13) but cause the bursting of a cartridge (11 or 12), the opening of the case (1) occuring only after a well defined cycle. |
