| abstract | A time-indicating apparatus based on the color change property of a reduced redox dye in the presence of oxygen is characterized by the initial introduction into a receptacle of a predetermined metered amount of a redox dye in its oxidized form together with a predetermined effective amount of a reducing agent in an alkaline medium. The conversion of the oxidized form of the redox dye into its reduced form occurs within the sealed receptacle. Precisely controlling the amount of both the oxidized dye and the amount of reducing agent introduced into the receptacle ensures that only a predetermined amount of the reduced form of the redox dye is able to be formed within the receptacle. The amount of reduced dye formed within the receptacle having a predetermined total surface area and the rate at which oxygen is able to enter into the receptacle allows the color transition time interval of the redox dye to the precisely controllable. Methods for making the time-indicating apparatus are also disclosed. Articles such as a container for a time-sensitive product and badge for indicating the expiration of a period of legitimacy incorporating the time-indicating apparatus are also disclosed. |
