Zusammenfassung:	PROBLEM TO BE SOLVED: To easily check generation of pin holes and defective sealing. SOLUTION: A carbon dioxide indicator to which an ink composition for detecting carbon dioxide containing one or more kinds of pH indicators, a binder and a solvent, and capable of easily and visually checking any color reaction of an indication unit by the carbon dioxide concentration is applied, and a vessel for chemicals which is formed of a carbon dioxide permeable plastic and stores the chemical containing bicarbonate are packaged in a gas- substituting manner in a carbon dioxide atmosphere.
