Abstract: In one aspect, a label (1) preferably intended for packages for goods, is provided which has, on one hand, a coloring substance of capacity of producing a print by effect of heat, the color of which print contrasts with the base color of the label, and on the other hand, an agent having the purpose of, at least partially, destroying the contrast between the colors, if the label is exposed to a temperature above a predetermined maximum value, the label having a surface field for a print in the form of a bar-code (3). The label is manufactured from a porous, capillary-suctioning material, in addition to which the agent is included in a loading of a substance (7) that is solid at temperatures up to the maximum value, but becomes liquid above the maximum value, the substance loading being located beside the surface field of the bar-code (3). A package for goods provided with a label, as well as a method and equipment for the application of labels to packages for goods, are also provided.

Abstract: A package (1) is provided for storing goods in a preservative state where the temperature must be maintained below a set value and having a bar-code (2) which is applied in a surface field (4) omitting extraneous prints and a temperature indicator (3) having variable optical properties when the temperature passes the set limit. The temperature indicator (3) at least partially overlaps the surface field (4) with one or more of the bars in the bar-code (2) being applied on top of the temperature indicator (3). A method for making the package (1) is also provided.

Abstract: 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.

Abstract: The invention relates to a package for goods having a bar-code (2) and a temperature indicator (3) having 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 connection to an outer code bar (4) thereof without covering the bar-code in order to, on one hand, in a first temperature state unimpededly enable scanning of the bar-code, but, on the other hand, after changing of the colour in the contrast medium make scanning impossible, more precisely by making an outer neutral field (5) opaque. The invention also relates to a temperature indicator as such as well as a method for marking packages.

Abstract: In a first aspect, the invention relates to a package (1) for keeping goods in a temperature-decreased, preservative state, in which the temperature should have a certain desired value. According to the invention, the package is connected to a temperature indicator (2) comprising means, which preserves a certain property when the temperature of the goods is decreased towards and past a predetermined limit value, which is at least somewhat higher than said desired value, but which alters this property in an irreversible way if the temperature during the storage would rise to or above said limit value. Advantageously, the temperature indicator (2) may be transparent as long as the temperature is lower than said limit value, but become opaque when the limit value is exceeded, e.g. in order to make reading of a bar-code (8) impossible. In a second aspect, the invention also relates to the temperature indicator as such.
