Package for storing goods in a preservative state as well as a method for making such a package

A package for storing goods in a preservative state in which the temperature may not pass a certain limit value, comprising, on one hand, a bar-code (2) of the type that between two outer, light-absorbing code bars (4), includes a plurality of intermediate and likewise light-absorbing code bars or marks (4) mutually spaced-apart by neutral, light-reflecting fields (5), outer, neutral fields (5) being found also outside the outer code bars, and on the other hand a temperature indicator (3), which comprises a contrast medium (8) contained between a front wall (6) and a base wall (7), which medium in a first temperature state is transparent or light-reflecting, but which on transition to another temperature state is triggered so far that the same is irreversibly converted to an opaque or light-absorbing colour, characterized in that the temperature indicator (3) is located beside the bar-code (2) in close vicinity of one of the outer code bars (4) thereof without covering the bar-code, in order to, on one hand, in the first temperature state thereof without hindrance enable scanning of the bar-code, but on the other hand, after triggering, make scanning impossible, more precisely by making an outer, neutral field (5) opaque or light-absorbing.
