PROBLEM TO BE SOLVED: To provide a production method of carbon dioxide gas-containing hot water significantly improving carbonate spring bathing effects such as blood circulation promotion, a production apparatus for easily producing the carbon dioxide gas-containing hot water, and a tablet for a carbon dioxide gas dissolver.SOLUTION: A carbon dioxide gas dissolver provides carbon dioxide gas-containing hot water by dissolving the carbon dioxide gas in a gas phase in hot water. The production apparatus of carbon dioxide gas-containing hot water combines (1) bicarbonate or (2) bicarbonate and organic acid to be dissolved in the hot water for acquiring the carbon dioxide gas-containing hot water. The carbon dioxide gas is dissolved in hot water with PH of not less than 6.0 and not more than 9.5 under the presence of (1) bicarbonate or (2) bicarbonate and organic acid.COPYRIGHT: (C)2014,JPO&INPIT【目的】 本発明は血行促進などの炭酸泉入浴効果を著しく向上させる炭酸ガス含有湯水の製造方法、及び前記炭酸ガス含有湯水を簡易に得られる製造装置、並びに炭酸ガス溶解器用剤を提供する。【構成】 気体状態の炭酸ガスを湯水に溶解して炭酸ガス含有湯水を得る炭酸ガス溶解器と、湯水に溶解させ炭酸ガス含有湯水を得る(1)重炭酸塩又は(2)重炭酸塩及び有機酸と、を組合せる炭酸ガス含有湯水の製造装置であって、炭酸ガスを(1)重炭酸塩又は(2)重炭酸塩及び有機酸の存在下で、PH6.0以上9.5以下の湯水に溶解させる構成であることを特徴とする炭酸ガス含有湯水の製造装置である。【選択図】 図1
