【Task】 It is an object of the present invention to provide a chlorine dioxide gas sustained-release device that can easily maintain generation of chlorine dioxide gas without leakage of liquid containing chlorine dioxide. [Solution] In a closed container (4) composed of a rigid member (2) and a flexible member (3) provided with an opening (1) for chlorine dioxide gas release, A bag filled and sealed with a chlorine dioxide aqueous solution or a chlorite aqueous solution, containing an aqueous solution bag (5) that can be broken by an external pressure applied through the flexible member (3), and a gelling agent (6). A sustained-release device for chlorine dioxide gas is used. The opening (1) for releasing chlorine dioxide gas is preferably closed with a gas permeable film (7) so that the chlorine dioxide aqueous solution or the chlorite aqueous solution does not leak. It is preferable to provide a bag breaking projection (8) in the sealed container (4) for helping to break the aqueous solution bag (5). [Selection] Figure 1 |
