Definitions

  • the temperature limit will be a maximum (rather than a minimum) temperature.
  • a particularly suitable way of producing the marking element as described in the previous paragraph is to print a layer of an ink on to a carrier sheet such that the channel is formed in the ink.
  • the absorbent material may be laid in position along the channel and then overlaid by a film providing the barrier layer.
  • the first material may then be provided in the region of the barrier layer above the absorbent material and the whole then- overlaid by a further film having a melting point higher than that of the barrier layer.
  • a probe heater to a temperature above the melting point of the barrier layer but below that of the outer film layer whereby the barrier layer is selectively punctured to "activate" the label.

Abstract

Elément marqueur destiné à indiquer si un état de température prédéterminé à été maintenu. Ledit élément (1) comporte un premier matériau (8) devenant fluide au-dessus d'un seuil de température prédéterminé, et séparé d'un second matériau absorbant (6) par une couche de séparation (7). Les premier et second matériaux sont tels que lorsque ladite couche de séparation (7) est percée et que le seuil de température prédéterminé est dépassé, le premier matériau (8) s'écoule le long du second (6) de manière à produire une modification détectable.
