PURPOSE: To simply perform pasteurization, disinfection or deodorization by providing the first storage section storing a material A, the second storage section storing a material B, a means communicating the first and second storage sections and bringing the material A and the material B into contact with each other, and an outflow hole feeding the generated pasteurizing, disinfecting or deodorizing gas to the outside of a container.

CONSTITUTION: The first storage section is watertightly constituted with a container main body 2 and a cover member 3, and the second storage section 4 is watertightly constituted with a tube body 5 and a partitioning cover member 6. A pressing bar 7 serving as a communicating means is provided at the portion corresponding to the second storage section 4. Water 10 as a material A is filled in the first storage section 1, and sodium hypochlorite powder 11 as a material B is filled in the second storage section 4. A protective cover member 12 is closed while a container is not in use so that an unnecessary external pressure is not applied to the top section 8. When the container is to be used, the protective cover member 12 is opened, the top section 8 is pushed in, and the partitioning cover member 6 is pushed by the tip of the pressing bar 7. The sodium hypochlorite powder 11 of the second storage section 4 is dropped and reacted with water 10 to generate hypochlorite gas. The hypochlorite gas flows to the outside of the container via a groove 9.
