Abstract

PROBLEM TO BE SOLVED: To make display label visually recognizable whether it has been heated or not, by coloring by heating so as to express a character or a figure showing that a commodity has been heated. SOLUTION: A thermosensitive coloring layer 6 coloring by heating is formed on one surface of a base material 5 of this display label 4 made of a paper or a plastic film, while a thermosensitive adhesive layer 7 is applied on the other surface as an adhesive layer. A concealing layer 8 formed on the surface of the thermosensitive coloring layer 6 covers areas except prescribed characters or letters to be colored by heating such as 'Heated' so that the coloring of the areas caused by heating do not appear. If required, pre-printing 9 is applied on the surface of the concealing layer 8 as fixed information. The concealing layer 8 is formed by coating, usually with colorless printing ink or the like containing a pigment such as calcium carbonate, or possibly with white or other color ink. The display label 4 is wholly white, while the thermosensitive coloring layer 6 can be colored in a single color or multicolor, such as black, red, or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display label having a heat-sensitive coloring layer which develops a color when heated.

[0002]

2. Description of the Related Art Conventionally, in a food section of a supermarket or a department store, there has been provided a service of placing a microwave oven and heating a packed product packed with prepared foods such as processed foods or a lunch box. However, for a while after heating in a microwave oven, the product itself is hot, and if it is touched without knowing that the product has become hot, problems such as burns and dropping of the product occur.

[0003] Electronic components that are destroyed by heat can be damaged by erroneous heat treatment. When the heat is cooled, it is possible to determine whether or not the electronic component has been exposed to heat treatment or high temperature. Problem that defective products are distributed.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is possible to visually judge whether or not a heat-treated product has been heated. Provide a display label to prevent burns and drop of products if touched without understanding. Further, the present invention provides a display label which can be determined even after the determination as to whether or not it has been exposed to a heat treatment or a high temperature, and which can be confirmed as a defective product.

[0005]

SUMMARY OF THE INVENTION The present invention focuses on the heat-sensitive coloring of characters and graphics by heating, and the coloring is achieved by heating the substrate or any one of the surfaces of the substrate. A display label having a heat-sensitive color-forming layer and partially coloring the heat-sensitive color-forming layer.

[0006] The display label is preprinted.

[0007] An adhesive layer is provided on the surface of the display label opposite to the surface on which the heat-sensitive coloring layer is provided.

[0008] Therefore, since characters and graphics indicating that the product has been heated can be displayed, the product can be visually recognized, and the product is carefully taken up.
No burns or falling items. Further, since it is possible to determine whether or not an electronic component or the like is erroneously heated for a long period after heating, the quality of the electronic component can be visually determined.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view of the display label of the present invention, and FIG. 2 is a sectional view taken along line II-II of FIG.

The display label 4 is provided with a heat-sensitive coloring layer 6 which is colored by heating on one surface of a base material 5 made of paper or plastic film, and a heat-sensitive adhesive layer as an adhesive layer on the other surface. 7 is applied. When a predetermined character, for example, a character such as “heated” is to be colored, a concealing layer 8 is provided on the surface of the heat-sensitive coloring layer 6 so that the region other than the character portion is not colored by heating. Also,
If necessary, the surface of the concealing layer 8 is pre-printed 9 as fixed information in advance.

The concealing layer 8 is applied with a printing ink, for example, a colorless ink containing a pigment such as calcium carbonate, but may be a white or other color printing ink. The entire display label 4 is white, and the heat-sensitive coloring layer 6 develops a color such as black or red. Each color can be colored as a single color or a plurality of colors as necessary.

The display label 4 configured as described above is a backing sheet 2 coated with a release agent 3 to protect the pressure-sensitive adhesive 7.
Is temporarily attached to. When sticking to a product such as a lunch box, the display label 4 is peeled off from the backing sheet 2 and attached to a lunch box (not shown). The lunch box to which the display label 4 is affixed is displayed, but may be heated in advance with a microwave oven (not shown) if desired. The lunch box heated and heated in the microwave oven itself is heated (heated),
In the display label 4, the character of "heated" is colored by heating, and the character can be visually recognized.

Even if such a heat-treated lunch box is displayed, the character of "heated" on the display label 4 can be recognized.
The purchaser can determine that the lunch box is heated and hot, and can purchase with care.

By attaching the display label 4 to an electronic component (not shown) or the like, the display label 4 can be used even if it is erroneously heated during the distribution process or if it is exposed to a high temperature for a long time. Since the exposed portion of the heat-sensitive coloring layer 6 is colored and the character of "heated" is colored, it is possible to determine that the electronic component has been heated or exposed to a high temperature, and it is highly likely that the electronic component has become defective. I can judge.

The display label 4 shown in the present embodiment has been described with an example in which the pre-printed display label 4 is affixed to the product, but the label continuum 1 in which a plurality of display labels are temporarily attached to the mount 2 is used. A desired character may be printed on a printer (not shown) and then attached to a product. The preferred printing position in this case is to print on the surface of the concealing layer 8.

In this embodiment, the character "heated" is colored. However, the present invention is not limited to this. Any character such as a character or a figure that can be visually recognized can be used. Although the pressure-sensitive adhesive layer has been described as an example of the pressure-sensitive adhesive layer, the pressure-sensitive adhesive layer is not limited to this, and can be applied to any pressure-sensitive adhesive.

[0017]

As described in detail above, the display label of the present invention can display characters and graphics indicating that the product has been heated, so that it can be visually recognized and attention paid to. Since the product is picked up, there is no burn or falling of the product. Further, since it is possible to determine whether or not an electronic component or the like is erroneously heated for a long period after heating, the quality of the electronic component can be visually determined.
