Embodiment Construction

[0031]A product package 2 is shown schematically in Figure 1, a label 1 affixed to the product package comprising a print 3 with information about the product in the package. The printed information may contain data on the product's characteristics, origin, price, best before date, etc. and is optically readable. The printed information is encoded, and in this case in the form of a barcode 3, which can be read optically by means of scanners commonly used by producers, sellers, and in shops and at checkouts.

[0032] The label 1 is made of a material for thermal printing and includes an upper layer 4 for said label prepared with a colouring substance or combination of substances which react with each other at a certain high temperature to take on the base colour of the label Contrasting colors, such as those mentioned at the beginning. The label includes an area or surface area for the printing or printing of the barcode 3 and does not occupy the entire surface of the label. ...

Abstract

In one aspect, the invention relates to a label (1) preferably intended for packages for goods, which label comprises, on one hand, a colouring substance of the type that has the capacity of producing a print by the effect of heat, the colour of which print contrasts with the base colour of the label, and on the other hand an agent having the purpose of, at least partially, destroying the contrast between said colours, if the label is exposed to a tem- perature above a predetermined maximum value, the label having a surface field for a print in the form of a bar-code (3). According to the invention, the label is manufactured from a porous, capil- lary-suctioning material, in addition to which said agent is included in a loading of a substance (7) of the type that is solid at temperatures up to said maximum value, but becomes liquid above the same, the substance loading being located beside the surface field of the bar-code (3). In other aspects, the invention also relates to a package for goods provided with a label, as well as to a method and equipment for the application of labels to packages for goods.

Description

technical field [0001] In a first aspect, the present invention relates to a type of label comprising, on the one hand, a colouring substance having the ability to produce an imprint by thermal effect, the colour of the imprint being contrasting with the base colour of the label, and on the other hand, the use of An agent that at least partially destroys the contrast between the colors if the label is exposed to a temperature above a predetermined maximum value, the label having a surface area for an imprint containing encoded information. [0002] In another aspect, the present invention also relates to a commodity package provided with a label. [0003] Furthermore, the present invention relates to a method and apparatus for applying a label to a package of goods. [0004] The commodity packaging in question is mainly used for food products that have a limited shelf life and therefore must be stored cold. For example, quick frozen foods should be stored below -18°C, while ...
