The surface forms a circulation flow SF (circulating turbulent flow) in the circulation space region CR (gas-liquid dissolving chamber MR). The circulation flow SF causes the bubbly water WG (water) to flow from the outflow interval δG along the bowl-shaped surface 26 and the inner peripheral surface 10C of the first container main body 10. It is a flow that flows along the rectifying surface (the flow dent curved surface 87A and the rectifying flat surface 4A excluding the flow dent curved surface 87A) and returns to the outflow interval δG.
