摘要： The present invention relates to a printed elapsed time-temperature indicating labels and to a method of indicating the elapse of a predetermined period of time and/or temperature. More' specifically the present invention relates to a device that measures and visually indicates the passage of a predetermined period of time and the various components of which can be formed by inexpensive printing methods and by lamination of one or more printed layers, which can be activated at point of use. The present invention is intended to provide a solution to the longstanding problems of providing an indication of the exposure of foodstuffs to unacceptable time and/or temperature conditions. In accordance with a first aspect of the invention, there is provided an elapsed time indicator comprising a liquid reservoir, a migration medium and a trigger; wherein the liquid reservoir is operable to release a liquid upon activation of the trigger into the migration medium, wherein the extent of absorption of the liquid from the trigger area can be determined by a change in colour or brightness of the migration medium and is an indication of one or both of differences in temperature and a passage of time.

摘要翻译： 本发明涉及印刷经过的时间温度指示标签和指示经过预定时间段和/或温度的方法。 更具体地说，本发明涉及一种测量和目视地指示预定时间段的通过并且其各种部件可以通过廉价的打印方法形成并且通​​过层压可以被激活的一个或多个印刷层的装置 在使用点。 本发明旨在提供一种长期存在的问题的解决方案，其提供食品暴露于不能接受的时间和/或温度条件的指示。 根据本发明的第一方面，提供了一种经过时间指示器，包括液体储存器，迁移介质和触发器; 其中所述液体储存器可操作以在将所述触发器激活到所述迁移介质中时释放液体，其中所述液体从所述触发区域的吸收程度可以通过所述迁移介质的颜色或亮度的变化来确定，并且是指示 一个或两个温度差异和时间的流逝。
