る。2. Description of the Related Art In recent years, environmental pollution of organic halogen compounds such as polychlorinated biphenyl (PCB) contained in industrial waste has become a problem. As one of the detoxifying methods of these organic halogen compounds, a method of decomposing the organic halogen compound by reacting the organic halogen compound with an alkali metal is known (for example, JP-A-49-82570;
JP-A-59-20179, Journal of the Chemical Society of Japan (11)
pp. 1577-1582 (1978), JP-A-9-216
No. 838, Japanese Patent No. 2918542 and the like. ). Among them, the methods described in Japanese Patent Application Laid-Open No. 9-216838 and Japanese Patent No. 2918542,
This is a method using an alkali metal dispersion, which can easily and efficiently decompose an organic halogen compound.
Since the preparation of the alkali metal dispersion needs to be performed under an inert gas atmosphere and in a water-free condition, it is usually performed in a laboratory having appropriate facilities. On the other hand, it is necessary to perform a decomposition treatment using the transported alkali metal dispersion in a place where an organic halogen compound such as PCB is stored.

There was a case. Therefore, it is necessary that the container for storing the alkali metal dispersion be one that shields the alkali metal dispersion from the outside air and seals it. In addition, the time from preparation and transportation of the alkali metal dispersion to the actual use thereof often takes one day to several months, during which time the alkali metal dispersion becomes non-uniform due to sedimentation. In some cases. Therefore, a container of the alkali metal dispersion requires some agitation means, and it is common to rotate the agitation blade with a motor before use to re-agitate the container. However, when the stirring blades and the motor vibrate during transportation, the seal portion is damaged, and if the sealing of the container is not maintained, the deterioration of the alkali metal dispersion due to the intrusion of outside air or other chemicals into the container or the like. In this case, a fire occurs in the motor portion, and other troubles occur due to leakage of the alkali metal dispersion from the seal portion.
