Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a reuse-prevention label, and particularly to a reuse-prevention label used for, for example, a price tag or a label attached to the opening of a container.

(Prior art) Conventionally, labels used as price tags to prevent repositioning are made by making appropriate perforations or cuts in the surface base material.
For example, if you try to remove it at a store and replace it with another price tag, it will separate and break at the perforations and cuts, and
There are known devices that allow you to tell at a glance that an attempt has been made to peel them off.

On the other hand, depending on the abrasive material on the opening of the package and its surface treatment method, the adhesive paper that is pasted to the opening of the container to indicate its unopened status may be used for products displayed on a store shelf. You can pick it up and easily peel it off on the spot, and then paste it back on so that no one knows that it was reprinted with foreign objects mixed into the package, so you can remove the sticker from the outside. You can't tell if the buff cage has already been opened just by looking at it. Therefore, there is a risk that the contents of the package may be tampered with. For example, poisonous substances may be mixed into candy packages.

Therefore, recently, adhesive labels that can be seen to be peeled off after being pasted have come on the market, and are disclosed in Japanese Utility Model Application Publication No. 59-1077.

This adhesive label is attached by peeling off the release sheet and pressing the exposed adhesive layer against the opening of the package (not shown). When the adhesive label affixed to the opening is peeled off, only the portion of the deposited film that was not directly deposited on the film substrate by the release agent coating remains attached to the opening. . Furthermore, if the opening is opened, the remaining vapor deposited layer stuck there will be cut or torn, thereby indicating whether the opening has been opened.

(Problems to be Solved by the Invention) However, in such adhesive labels, metal is vapor-deposited on the film base material and the release agent coating layer, so the film as the material to be vapor-deposited is limited to polyester, etc. Furthermore, in order to complete the vapor deposition, it is necessary to satisfy various other conditions, which has the disadvantage of increasing costs.

In addition, when the film is peeled off, a part of the vapor deposited film is difficult to remain on the adhesive coated surface, and it is peeled off while adhering to the film surface, making it difficult to form characters etc. with the remaining vapor deposited film. It can't be done. Furthermore, when the film base material is peeled off, a part of the adhesive coating remains on the adhesive part of the material to be adhered, and the surface of the exposed adhesive coating becomes sticky and attracts dust. However, there were also problems in terms of hygiene.

Therefore, the main object of the present invention is to provide a label that can be recognized as having been peeled off after being pasted, does not become sticky due to adhesive buildup on the peeled surface, and does not require a vapor deposition process. be.

(Means for Solving the Problems) This invention provides a first scrap, an adhesive layer laminated on one main surface of the first layer, and between the first layer and the adhesive layer, A portion is removed so that the first layer and the adhesive layer are in direct contact with each other,
M-layered release agent layer, a second layer adhered to the first scrap by the adhesive layer and laminated, and a third layer laminated on the main surface of the second layer, In the region where the release agent layer is not formed, the second layer is adhered to the first layer by an adhesive layer, and the second layer is separated from the reuse prevention type label.

(Function) The third layer prevents the adhesive layer from being scratched when the second layer is peeled off.

When the first layer is peeled off, a portion of the second layer is pulled away while being adhered, and the first layer and other portions maintain their initial state.

The release agent layer allows the second layer and the first layer to be easily separated.

The first layer protects the second layer from cutting or tearing.

(Effects of the Invention) According to the present invention, since the second layer is laminated on the first layer by the adhesive force of the adhesive layer, it can be produced without performing vapor deposition as in the conventional method. Moreover, in the part where the release agent layer has been partially removed, the second eyebrow is torn from the remaining part with the second layer and the first layer adhering to each other, and the part that remains is torn together with the first layer. The remaining part can be used to draw various double lines, for example, characters such as ``opened''. Additionally, once the second layer is cut or torn, it does not return to its original state, indicating that the second layer has been separated. Therefore, it can be seen at a glance that the attached label has been peeled off, and a label that does not require the conventional vapor deposition process can be obtained.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Embodiment) FIG. 1 is a sectional view showing an embodiment of the present invention. The label 10 of this example is temporarily attached to a release sheet 12, and an adhesive layer 14. Third layer 24, second layer 22, adhesive N16. The peeling agent layer 18 and the first layer 20 are
They are layered in sequence. A printed layer 26 is formed on the surface of the first layer 20.

The adhesive layer 14 is for providing adhesive force to the label 10, is made of an adhesive such as a pressure-sensitive adhesive, and is formed between the release sheet 12 and the second Jii 22.

The second layer 22 is formed of aluminum foil or a resin film formed by coating a synthetic resin containing silver powder, gold powder, carbon black, or other pigments. This second layer 22 is for sealing the opening of the package, for example, and is also for opening the package by being cut or torn to create an unsealed state.

Adhesive layer 16 that adheres second layer 22 and first layer 20
is formed by coating the surface of the release agent layer 18 with a two-component reactive polymer resin such as urethane resin, other EVA resin, PVA, vinyl acetate, and acrylic resin. In addition,
Other examples of the adhesive layer 16 include an adhesive layer coated with a thermosetting adhesive such as polyester or polyurethane.

The release agent N18 is formed to facilitate the separation of the adhesive layer 16 and the first layer 20 so that they cannot be reattached, and is made of, for example, silicone resin, fluororesin,
It is formed between the adhesive layer 16 and the first 7520 by applying a release agent such as Wanx. This release agent layer 18 is formed on a part of the surface of the first layer 20, and for example, in the part where the release agent layer 18 is removed, double lines such as "opened" are formed. .

The first layer 20 is formed to prevent the adhesive layer 16 from being cut or torn, and is temporarily attached to the adhesive layer 16 via the release agent layer 18. The formed portion is in close contact with the adhesive layer 16. Examples of the first layer include relatively stiff materials such as polyester or nylon film.
Materials that do not shrink easily due to heat, such as paper or synthetic paper, can be used, but when this label is folded and attached to the sealing area, the first layer 2 resists the adhesive force of the adhesive layer 16.
It is preferable to use a relatively flexible material that does not peel off when the 0 tries to restore its original state.

The third FIF 24 prevents the adhesive layer 14 from being exposed when the second layer 22 is peeled off as described below, and is formed by coating with ethylene, vinyl acetate copolymer, or the like.

The release sheet 12 is for protecting the adhesive layer 14, and includes a release paper made of, for example, a paper 9 synthetic resin sheet, and a release agent such as silicone is coated and printed on the surface of a base material such as paper. A release agent Fi 12 a is formed.

As shown in FIG. 2, in this label 10, the force required to separate the first layer 20 from the adhesive layer 16 by the release agent layer 18 is a, and the adhesive layer 14 is attached to the adhered material. The adhesion force with the adhered material when bonded to the second layer 2 is b, and the second layer 2
If the force required to destroy the release sheet 12 is C, and the force required to peel the release sheet 12 from the adhesive layer 14 is d, then the force required to peel each part is expressed by the formula d<a<c<
Configure so as to satisfy b.

First, the label IO is peeled off from the release sheet 12, and is pasted on the adhesive layer 14 as a price tag or on the opening of a candy package, for example, as shown in FIG.

In order to open the opening of the package to which the label 10 made of the first 520, adhesive layer 16, etc. is attached, the attached label 10 must be peeled off and the sealed portion must be opened. In this case, the first layer 20
is weakly temporarily attached to the adhesive layer 16 via the release agent layer 18, while the second layer 22 is strongly attached to the opening of the package with the adhesive masonry 4, as shown in FIG. In the part of the release agent layer 18, when trying to remove the label 10, only the first layer 20 can be removed, and the adhesive layer 16 and the second layer 22 remain attached to the sealing part together with the adhesive layer 14. remain. As shown in FIG. 2, since the second layer 22 is bonded with the adhesive layer 16 in the part where the release agent layer 18 is missing, the second layer 22, which is relatively easy to tear, is The adhesive layer 18 is torn at the boundary between the part where the release agent layer 18 is formed and the part where it is not formed, and is peeled off from the adhesive layer 14 together with the first layer 20 .

Therefore, once the first layer 20 is peeled off, the first layer 20 cannot be reattached to the surface of the adhesive layer 16 and the original state cannot be restored, so the package is in an unsealed state. This is obvious at a glance.

In order to completely open the opening of the package, the remaining adhesive layer 16 and the third
layer 24 must be cut, torn, or peeled away from the opening.

Note that even if the adhesive layer 16 is cut or torn at the same time when the first layer 20 is peeled off to open the sealed part, the unsealed state can be determined by looking at the state of the adhesive layer 16 in the same way as above. be.

In this example, the label 10 was used for a package of sweets, but it could also be used for a medicine package, for parts to be sealed such as two envelopes, and as a price tag displaying the price. Of course.

Here, more specifically, it is as follows.

(1) Use a polyester film with a thickness of about 50 g as the first layer, use silicone resin manufactured by Toshi Co., Ltd. as the release agent to form the release agent layer, leave some parts uncoated, and apply the curing agent. After coating with the film, a release agent layer is partially formed by baking with a dryer. Next, a urethane resin forming an adhesive layer is coated on the release agent layer to a thickness of about 5 to 50 microns. Furthermore, aluminum foil was laminated on the surface of the molten urethane resin, and the urethane resin was dried and solidified. Furthermore, the surface of the aluminum foil was coated with EVA resin shown in Table 1 below. At this time, the force required to peel off the urethane resin layer from the release agent layer was 50 g.

Separately, a release sheet is produced by coating a release paper manufactured by Shikoku Paper Industries with an acrylic adhesive (BPS-5127) manufactured by Toyo Ink to a dry film thickness of 5 to 50 μm. After that, it was laminated with the multilayer product. At this time, the force (c) required to tear the second layer was 100 g, and the force (d) required to peel the release paper from the adhesive was Log. The thus constructed pressure-sensitive adhesive paper was made into a label and pasted on a material to be pasted (paper surface, plastic, glass bottle, etc.). At this time, the adhesive force (b) to the adhered material was i, 500 g. When I tried to forcibly remove the attached label from the material to which it was attached, the first layer of film was peeled off from the adhesive layer along with the aluminum foil in the area where the release agent layer was not formed. .

(The following is a blank space) (2) A nylon film with a thickness of about 70 g was used as the first layer, and wax was applied as a release agent to form a release agent layer and dried. Next, a polyester adhesive or the like that forms an adhesive layer is coated on the wax to a thickness of about 5 to 50 mm. Furthermore, aluminum foil was laminated on the surface of this molten adhesive, and the polyester adhesive was dried and solidified. Furthermore, the surface of the aluminum foil was coated with EVΔ resin. At this time, the force (a) required to peel off the adhesive from the wax surface was 50 g. The multilayer product of the nylon film and the second layer thus prepared was laminated with a release sheet prepared by coating release paper with an adhesive to a dry film thickness of 5 to 50 μm. At this time, the force (d) required to peel off the release paper from the adhesive was Log. The pressure-sensitive adhesive paper thus constructed is made into a label and attached to the material to be affixed (paper surface,
(plastic, glass bottles, etc.). At this time, the adhesive strength (b) to the adhered material was 1.5°Og. When I tried to forcibly peel off the attached label from the material to which it was attached, the first layer of film was peeled off along with the portion of the aluminum foil where the release agent layer was not formed.

The coating device 116' includes two rollers 112' and 11
4' included. The lower part of the roller 112' is immersed in a resin 16a such as urethane resin or EVA resin stored in a pan. Therefore rollers 112' and 114'
By rotating the film 2o, the resin 16a is printed and coated on the surface of the release agent layer 18 of the film 2o guided between them. The film 20 coated with the resin 16a is further led to a dryer 120, where it is dried and solidified. By this, on the surface of the first layer 20,
The surface of the first group U agent layer 18 is coated with resin 16a to form an adhesive layer 16, and then sent to the next third layer laminating device 11O'. The laminating device 110' is comprised of a known printing machine or coating device, such as an offset printer rt+Ji2i, and is provided on the transport path of the substrate 30. Then, the surface of the adhesive 1' 516 is coated with a resin mixed with gold powder or silver powder by this laminating device 110', and the second shoe 22 is formed.

FIG. 9 is a sectional view of another embodiment.

In this embodiment, appropriate double-line lines 23 are printed on the surface of the aluminum foil or resin film forming the second layer 22, and when the first layer 20 is peeled off, the double-line layer 23 is printed. It is formed so that 23 is visible. This double line layer 23
For example, if the material forming the second layer 22 is aluminum foil, it is formed on the surface of the second layer 22 in advance and laminated. Moreover, when the second layer 22 is formed by coating with resin, printing may be performed after the resin film is formed. Also, on the back side of the third layer 24, an appropriate double line layer 2 is formed.
5 is printed and formed so that when the second layer 22 is separated from the third layer 24, the third layer 24 can be seen through. This double line layer 25 is formed by printing after the third layer 24 is formed.

Note that both line layers 23 and 25 may be colored by applying a paint or the like using an appropriate coating device.

By combining the two types of double-line layers 23 and 25, a predetermined character or pattern may be formed when the first layer 2o is peeled off.

As the synthetic resin that forms the resin film, we select a synthetic resin that is made by blending a total bending powder with a synthetic resin that can be cut or torn by applying a relatively weak force, and then coat it. A second layer 22 may also be formed.

In addition, if the second layer 22 is difficult to separate from the third layer 24 as shown in FIG. layer 2 of 2
After 2 is laminated and formed, a release agent such as silicone resin may be applied to the main surface thereof to make it easier to separate.
