A housing for the protection of explosive charges comprises several layers of different compositions surrounding the explosive charge. The successive layers have alternately a high and a low shock wave impedance, where further the outermost layer has the lowest melting point and the melting point increases toward the innermost layer.

A casing for the protection of explosive charges, comprising a plurality of layers of different compositions surrounding the explosive charge, said layers being successively arranged including an innermost layer adjacent said charge, an outermost layer the furthest from the charge in an envelope layer covering said outermost layer, said layers having successively different shock wave impedances alternating between a relatively high shock wave impedance and a relatively low shock wave impedance relative to each other and having different melting points, said envelope surrounding said outermost layer having at least one opening therein, the melting points of successive layers being different with the outermost layer having the lowest melting point and said layer adjacent said charge having the highest melting point so that upon heating the temperature at the explosive charge is the smallest, said outermost layer contiguous to the surrounding envelope having a high shock wave impedance, the next innermost layer having a low shock wave impedance, the next innermost layer having a high shock wave impedance and the layer contiguous to the explosive charge again having a low shock wave impedance.
