A mobile container in which an explosive, such as an infernal machine or a time bomb, can be placed after discovery for transport to a suitable location for disarming and whereby, in the event of an accidental explosion within the container, there will be no resultant injury to persons or damage to property adjacent thereto. The container has an upright cylindrical shape with the shell and base thereof being made of aluminum armor plate. A cover, pivotally connected to the top of the container, is made in the form of a ballistic grille to vent explosion gases in an upwardly direction, and a wheel suspension system is provided allowing the container to resiliently deflect downward in response to a detonation within the container so as to seat the container upon the wheel support surface and thereby prevent damage to the wheel suspension system.
