A container system which can provide for a wide variety of explosive charge configurations, including a suspended spherical or elliptical charge, using a container system which provides minimum interference with the action of the explosive agent while allowing the use of inexpensive liquid or pourable explosive agents. An important property of the invention is that of introducing a minimum of contamination into the blast field created by the detonation of the explosive agent. Therefor it is an objective of the invention to impose a minimum of non-explosive mass of the container system upon the overall mass of the system and its explosive agents.
