ケーター。[Claims for Utility Model Registration] 1. An indicator characterized by containing a drug that reacts with oxygen and covering its surface with a film that allows oxygen to permeate over time. 2. An indicator characterized by containing a pre-moistened display material whose display color varies depending on the amount of water it contains, and covering this with a moisture-permeable film that allows water vapor to pass through. 3. An indicator characterized by encapsulating calcium chloride and covering it with a moisture permeable film. 4. An indicator characterized by containing a drug that causes changes such as discoloration by absorbing carbon dioxide, and covering this with a carbon dioxide selectively permeable membrane.
