PURPOSE: To obtain a blast-resistant container having a simple structure, being light in weight and having reduced bulkiness by a method wherein an inner compressible layer of a mixture obtained by putting vermiculite in a binder is formed inside a high-strength outer housing.

CONSTITUTION: A blast-resistant container is composed of a high-strength housing 20 on the outside, an inner liner 24 separated from the inner surface of the outer housing and an inner compressible layer 26 of a mixture of vermiculite with gypsum or cement. An excellent effect is obtained in the case when the vermiculite has an average grain size of 5-10 mm and when a binder is the gypsum or the cement. The ratio of the vermiculite to the binder is preferably 2:1 to 10:1 on a volume basis. When the content of the vermiculite is made below 2:1, absorption of the energy of blast before transmitted to the outer housing becomes low, although resistance to penetration of fragments becomes high. When it is increased above 10:1, the resistance becomes small, although the absorption of the energy becomes high.
