The invention discloses a foam metal sandwiched closed spherical anti-explosion container. The foam metal sandwiched closed spherical anti-explosion container is high in designability, low in manufacturing cost and weight, simple in structure, convenient to operate and high in anti-explosion capacity. The foam metal sandwiched closed spherical anti-explosion container comprises two symmetrical hemispherical bodies. Each hemispherical body comprises an inner face plate, an outer face plate and foam metal, wherein the inner face plate and the outer face plate are arranged as hemispherical faces, and the space between the inner face plate and the outer face plate is filled with the foam metal. A flange is fixed to the end face of each outer face plate. The two hemispherical bodies are connected into a closed cavity spherical body through the mutually fixed flanges. A spherical cavity defined by the inner face plates is used for containing explosives, and a uniformly distributed foam metal sandwich layer is formed between the inner face plates and the outer face plates. The inner face plates and the foam metal sandwich layer can be plastically deformed to a great extent so as to absorb a large amount of explosion impact energy, and the speed of explosive debris in high speed motion is lowered, so that the influences of explosion impact waves on the outer face plates are effectively reduced, the impact resistance of the anti-explosion container is improved, and harms of the explosion impact waves to protected persons and the surrounding environment are greatly reduced.
