Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a display label that is applied to the surface of containers such as metal cans and bottles for packaging foods, beverages, and other products.

[Conventional technology and problems]

Information about the product (contents) is displayed on the body surface of metal can containers such as aluminum cans and tin cans used as sealed packaging materials for foods, beverages, and other products, as well as product image and design effects. In order to improve the product's quality, trademarks, letters/symbols, designs, designs, etc. are often printed.

Can containers with such required markings are manufactured through a can manufacturing process and a printing process, but the entire amount of manufactured can containers is not necessarily used as packaging containers as planned. However, some of them are often left unused due to changes in product demand and supply, changes in sales plans, etc. However, the surface of the body of the can container has printing related to the originally planned product, and this can also be used as a can container for packaging other products of different brands and types. Instead, they have no choice but to collect them as scrap, resulting in significant waste.

In addition to metal cans, plastic bottles, glass bottles, etc. have similar problems.

The present invention provides a label to solve the above problems.

[Means and actions for solving problems]

A tube-shaped label that is attached to the body surface of a container using heat shrinkage force and the adhesive force of an adhesive, in order to attach display content different from the display content printed on the body surface of the container. A printing ink layer for displaying the contents, a concealing ink layer for concealing the surface of the body of the container, and an adhesive layer are laminated in this order on the inner surface of the heat-shrinkable film, The hiding ink layer is characterized in that it can be peeled off from the heat-shrinkable film.

The fact that the hiding ink layer can be peeled off from the heat-shrinkable film means that if a force is applied to peel off the label of the present invention after it has been applied to the surface of the body of the container, the heat-shrinkable ink layer will peel off from the heat-shrinkable film. This means that even if the adhesive film detaches from the container surface, the hiding ink layer does not detach and remains attached to the container surface together with the adhesive layer.

The releasability of the above-mentioned hiding ink layer from the heat-shrinkable film is determined by, for example, a masking ink whose adhesion to the heat-shrinkable film surface and the printing ink layer is lower than the adhesion at the interface with the adhesive layer. or by providing a release ink layer between a heat-shrinkable film provided with a printing ink layer and a masking ink layer.

When the label of this invention is attached to the surface of a container such as a metal can or glass bottle, the surface of the container is hidden by the hiding ink layer laminated to the printing layer of the film. design,
Even if other indications are printed, the printing and
There is no overlap or confusion with the printed layer of the label.
The colors and patterns of the printed layer of the label can be clearly visualized. Furthermore, even if a force is applied to peel off the label of the present invention attached to the container surface, the hiding ink layer will not be peeled off together with the film and will remain on the container surface. Since the concealment function is maintained, the printed display contents on the container surface are not exposed.

〔Example〕

The label of the present invention is explained with reference to the attached drawings.
FIG. 1 is a cross-sectional view showing the layered structure of the label 10 of the present invention, where 11 is a heat-shrinkable film (hereinafter also referred to as "base film"), and 12 is a print formed on the surface of the base film 11 by printing. Layer 13 is an opaque ink layer laminated and printed on the printed layer 12, and 14 is an adhesive layer applied to the surface of the opaque ink layer 13.

FIG. 2 shows an example in which the label 10 of the present invention is formed into a tube shape before being fitted into a container such as a can, and an adhesive layer 14 is located on the inside, and a printing layer 12 is formed from the outside. Display contents M10 (the characters "ABC" in the figure) are visible.

As shown in FIG.
It is placed on a container 20 on which 0 is printed, and is shrunk by being subjected to a heat shrinkage treatment such as blowing hot air, and due to the shrinkage force and the adhesive force of the adhesive layer 14 on the inner surface, as shown in FIG. It is closely integrated with the surface of the container 20. Note that the label 10 does not necessarily have to be formed into a tube shape in advance, but can be prepared as a sheet, wrapped around the container 20 with the adhesive layer 14 on the inside, and bonded using the overlapping edges at both ends as an adhesive margin. Alternatively, the tube may be formed into a tube and then heat-shrinked.

By applying the label 10 of the present invention to the surface of the container 20 in this way, the printed display content M20 on the surface of the container 20 is hidden from view by the hiding ink layer 13, and only the display content M10 by the printed layer 12 is clearly visible. be seen.

The base film 11 of the label 10 of the present invention is, for example, a heat-shrinkable plastic film such as polyvinyl chloride, polyethylene, polypropylene, etc. If desired, a laminate film in which different types of films are laminated may be used.

The printing layer 12 is formed by printing appropriate colored ink in a pattern corresponding to a predetermined display content, and is formed by multicolor printing using two or more colored inks, if necessary.

The hiding ink layer 13 is typically printed with white or silver-white printing ink, and it visually blocks the printed display content on the container surface and is used to hide the label 1.
It may be any opaque ink that can prevent visual confusion due to overlap with the printed layer 12 of 0.

As the adhesive 14, a pressure-sensitive adhesive, a heat-sensitive adhesive, or the like can be used.

By the way, during the distribution process of a product having the label 10 of the present invention attached to the surface of the body of the container 20, tampering such as peeling off the label 10 to expose the display contents printed on the surface of the container is prohibited. No. Furthermore, if part of the label 10 peels off from the surface of the container 20 for some reason after the product reaches the consumer, the display content M20 on the container surface, which is completely unrelated to the display content M10 on the label 10, may You can't help but feel strange when exposed. In view of this point, in the present invention, the concealing ink layer 13 is provided on the base film 11 so that it can be peeled off. This releasability can be achieved, for example, by using a concealing ink that has lower adhesion with the base film 11 and the printing ink layer 12 applied thereto than with the interface of the adhesive layer 14. Granted. The level of adhesion can be adjusted arbitrarily by selecting the ink vehicle (resin), etc. By doing so, even if the label 10 is peeled off, the interface between the printing layer 12 and the hiding ink layer 13 becomes the peeling surface, as shown in FIG. 20
Since it remains as it is on the surface, the printed display M20 on the surface of the container 20 is not exposed. In this case, instead of providing the adhesive layer 14 uniformly over the entire back surface of the label, it is provided in a suitable pattern, for example an "x" pattern, so that when the label is peeled off, the hiding ink layer 13 is If the adhesive is made to selectively remain on the container surface in accordance with the "X" pattern, the appearance of the "X" mark will indicate that the displayed content M20 on the container surface is unrelated to the contents of the container. This can be visually recognized by consumers.

Alternatively, as shown in FIG. 2, if a release ink layer 15 is provided between the base film 11 on which the printing layer 12 is applied and the hiding ink layer 13, the release ink layer Since 15 serves as a peeling surface, exposure of the printed display M20 on the surface of the container 20 can be prevented in the same manner as described above. In this case as well, if the release ink layer 15 is applied in an appropriate pattern,
When the label is peeled off, the masking ink layer 13 remains along the pattern on the container surface together with the adhesive layer, thereby achieving the same purpose as described above.

Note that if the adhesive layer 14, release ink layer 15, etc. of a label having the layer structure shown in FIGS. 1 and 2 are applied in an appropriate pattern instead of uniformly over the entire surface of the label, The masking ink layer 13 can be selectively left on the container surface along the pattern as shown in FIG. It can also be used as so-called hidden printing if it is applied in a pattern that indicates hits and misses and the product purchaser is asked to peel off part of the label.

The type of container 20 in which the label 10 of the present invention is used is arbitrary, such as a metal can, a bottle, etc.
Regardless of the material. Even if the container 20 has an unusual shape such as a gourd shape or a Daruma shape, the base film 11 has heat shrinkability, so the heat shrink treatment will eliminate wrinkles and wrinkles even on the uneven surface. It is possible to tightly adhere the container to the surface of the container by the adhesive force of the adhesive layer 14, without causing any bulges or the like.

In addition, when the container 20 is a can container, the edge portions 10, 1, 10, 2 of the label 10 of the present invention are caught in the tightened portion between the body body material and the top surface member of the can, or , the container 20 and the label 1 are attached by holding the edge portions 10, 1, 10, 2 to the top member.
It is possible to enhance the sense of closeness and unity with 0. FIG. 4 shows the label 10 of the present invention attached to a so-called two-piece can consisting of a top body 21 and a top member 22.
In this example, the upper end edges 10, 1 are bitten into the rolled-up part 24, and the lower end edges 10, 2 are hugged to the peripheral edge of the bottom surface 23 of the trunk body material 21. be. In this way, the edge 1 of the label 10
Container 20 and label 10 at 0, 1, 10, 2
Since the overlap is visually hidden, a visual effect as if the display content M10 of the label 10 were printed directly on the surface of the container 20 can be obtained. If the can container 20 is a three-piece can, such as a canned can, consisting of a cylindrical body body and two top members that are attached by tightening the top and bottom ends, each of the top and bottom ends is tightened. Invented label 10 on the section
The same visual effect as above can be obtained by engaging the upper and lower end portions 10, 1, 10, 2, respectively.

Depending on the type of contents to be filled into the container 20, if heat sterilization is performed after filling and sealing the contents, the label 10 is heat-shrinked using the heat of the heat sterilization process. You can do it like this. Further, when the adhesive 14 of the label 10 is a heat-sensitive adhesive, it is possible to generate adhesive force and bring the label into close contact with the surface of the container 20 at the same time as the label thermally shrinks.

[Effect of idea]

By using the label of this invention, even if a label for packaging another product is printed on the surface of the container, the container can be repurposed as a container for packaging a product of a different type or brand than what is displayed on the surface. be able to. Therefore, even if a large amount of containers prepared as product packaging containers remain unused due to a change in plans, they can be used effectively without being scrapped, and economic losses can be avoided. In addition, even if the label is peeled off during the distribution process of products with the label of this invention attached to the surface of the container, the concealment function will not be impaired, so there is no possibility of tampering that would expose the printed content on the surface of the container. It is possible to prevent such acts, and furthermore, there is no concern that consumers will be confused even if the label peels off after reaching the consumer's hands, so its practical value is extremely large.
