PURPOSE:To increase the amount of carbon dioxide dissolved in a liquid within a definite time, by providing the carbon dioxide injection hole from a carbon dioxide jet mechanism to a lid and attaching a jet pipe reaching in the vicinity of the inner bottom of a container from said injection hole to the lid. CONSTITUTION:A liquid L is received in a container 1 and a lid 2 is threaded with the container 1 to hermetically close said container 1 and, thereafter, carbon dioxide is supplied to an injection hole 21 from an external carbon dioxide emitting mechanism. Carbon dioxide reaches in the vicinity of the inner bottom of the container 1 through a jet pipe 27 and forcibly opens a check valve 28 to be injected from a nozzle 29 to be sent into the liquid L. Because the fine dividing effect of bubbles by the nozzle is high and the gas passing distance from the jet position to the surface of the liquid is long, the stagnation time of the gas in the liquid is long and the gas is sufficiently dissolved in the liquid. A stopcock 24 is unscrewed to be detached from the lid 2 and excessive gas is vented from a small hole 25 and, thereafter, the lid 2 is detached and the container 1 is tilted to take out the liquid including the gaseous component.
