Abstract
An integrating temperature-time indicator comprising: a hermetically closed envelope having upper and lower walls, each of them made of a gas-impermeable material, both walls being hermetically closed around their periphery; sealing means dividing said casing into a first indicator section and a second gas generation zone; a gas-generating material, in the second section; wick means extending from the first section to the second section, the wick means being the only means of communication of the gas between said sections, and an indicator composition that produces a color change in the presence of the gas being deposited on said wick generated by said gas-generating material.
