Patent

CA 2505927

The invention relates to a package for goods having a bar-code (2) and a temperature indicator (3) including a contrast medium between a front wall and a base wall. According to the invention, the temperature indicator (3) is placed beside the bar-code (2) in close vicinity of an outer code bar (4) thereof without covering the bar-code, in order to, on one hand, in a first temperature state without hindrance enable scanning of the bar-code, but, on the other hand, after a colour alteration in the contrast medium make scanning impossible, more precisely by making an outer neutral field (5) opaque. The invention also relates to a method for marking packages.

L'invention concerne un conditionnement pour des marchandises, présentant un code à barres (2) et un indicateur de température (3) contenant un milieu de contraste entre une paroi frontale et une paroi de base. Selon le mode de réalisation décrit dans cette invention, l'indicateur de température (3) est placé à côté du code à barres (2) à proximité d'un code à barres extérieur (4) sans recouvrir le code à barres, de manière, d'une part, à permettre le balayage du code à barres sans gêne, dans un premier état de température et, d'autre part, à empêcher le balayage après une altération de la couleur du milieu de contraste, plus précisément en rendant opaque un champ neutre extérieur (5). La présente invention concerne également un procédé de marquage de conditionnements.
