    Abstract: An indicator and method for showing an expiration of a predetermined, temperature-dependent time period, which indicator has a first element (1), containing a coating layer (4) and a second element (2) containing an activating layer (10). The indicator is activated while taken into use by placing the first (1) and second element (2) into contact with each other. Before the activation of the indicator in the coating layer (4) there is a visually distinctive colour zone (8) the colour of which changes after the activation of the indicator due to time and temperature effect.
