Title (EN) THERMAL-SENSITIVE APPEARANCE-CHANGING LABEL
(FR) ÉTIQUETTE THERMOSENSIBLE CHANGEANT D'ASPECT
Abstract:
(EN) A thermal -sensitive label includes a label-specific set point temperature visually displayed thereon, and a thermal indicator that changes visual appearance in dependence upon temperature change in comparison with a threshold temperature. The threshold temperature of the thermal indicator is set during manufacture to be a fixed amount above the set point temperature. The thermal indicator has a first visual appearance when a temperature measured by the thermal indicator is below the threshold temperature. The thermal indicator dynamically changes to a second visual appearance different than the visual appearance when a second temperature measured by the thermal indicator exceeds the threshold temperature. A label kit includes multiple labels with a variety of different set-points. Each of the labels may include one or both of a reversing thermal indicator for comparing current temperature to the threshold temperature and a non-reversing thermal indicator for comparing a maximum temperature to the threshold temperature.
(FR) Étiquette thermosensible comprend une température de point de consigne spécifique de l'étiquette affichée visuellement sur celle-ci, et un indicateur thermique qui change l'apparence visuelle en fonction d'un changement de température par rapport à une température seuil. La température seuil de l'indicateur thermique est réglée pendant la fabrication pour être une quantité fixée au-dessus de la température de point de consigne. L'indicateur thermique a un premier aspect visuel lorsqu'une température mesurée par l'indicateur thermique est inférieure à la température seuil. L'indicateur thermique passe de manière dynamique à un second aspect visuel différent lorsqu'une seconde température mesurée par l'indicateur thermique dépasse la température seuil. Un kit d'étiquettes comprend de multiples étiquettes ayant une variété de points de consigne différents. Chacune des étiquettes peut comprendre un ou les deux indicateurs thermiques d'inversion pour comparer la température actuelle à la température seuil et un indicateur thermique non réversible pour comparer une température maximale à la température seuil.
