Method of preparing sterile water containing hypochlorous or chlorous acid, package of sterile source materials, sterile water preparation kit, method and apparatus for spatial sterilization

   
   

The upper end of a cylinder (8) located in a mouth (3) of a bottle (2) abuts the top plate (5b) of a seal cap (5). The cylinder (8) has formed in the outer surface thereof a circumferential recess (10) normally sealed by a sealing member (9). The bottle (2) contains hydrochloric acid (second component) of a diluted concentration, while the circumferential recess (10) in the cylinder (8) contains sodium hypochlorite as a first component. When a user removes a stopper ring (6) and next turns the seal cap (5) in the tightening direction, the circumferential recess (10) moves to and below the sealing member (9) and permits the first component to flow into the bottle (2) and mix with the second component. As a result, sterile water of a pH level within the slightly acidic or neutral region is produced. Then, the user can use the prepared sterile water for sterilization by hypochlorous acid.
