摘要： A tamper-proof barcoded quality indicator operative to provide a machine-readable indication of exceedance of time and temperature thresholds following actuation thereof, including a first barcode including a first colorable area and being machine-readable before exceedance of the time and temperature thresholds, a second barcode including a second colorable area and not being machine-readable before exceedance of the time and temperature thresholds, a coloring agent located at a first location on the indicator, a coloring agent pathway operative to allow the coloring agent to move, at a rate which is at least partially a function of time, from the first location to the first and second colorable areas simultaneously for simultaneous coloring thereof upon exceedance of the time and temperature thresholds, thereby causing the first barcode to become unreadable and at the same time causing the second barcode to become machine-readable, and a tamper-proof actuator element operative to actuate the indicator.

摘要： An activatable quality label operative to provide an indication of exceedance of a temperature threshold following activation thereof at a temperature less than or equal to an activation temperature, including a readable indicator located on the quality label and operative, following activation of the quality label at or below the activation temperature, to readably indicate exceedance of the temperature threshold, an actuator element operative to activate the quality label and indicia at least partially formed by thermochromic ink, the thermochromic ink having a first visual appearance at temperatures less than or equal to the activation temperature and a second visual appearance at temperatures above the activation temperature, such that a visual appearance of the indicia is indicative of whether the quality label is at a temperature less than or equal to the activation temperature and hence may be activated.
