Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is particularly useful as a chargeable sticker for garbage bags, a seal sticker that cannot be peeled off illegally, a price display label, etc., and the traces after peeling off the sticking object or the label itself. Regarding the label that remains clearly in.

[0002]

In recent years, many municipalities have been charged a fee for waste disposal. In order to reuse resources or reduce disposal costs, various types of waste generated from general households and business establishments are sorted based on established standards, collected, and then transported to their respective treatment plants. Disposal fees differ depending on the type of garbage, and the way of paying the fees varies depending on the municipality, but generally, the costs are borne by purchasing designated collection bags, fs, labels, etc. for each type of garbage. Has been done.

By the way, when a label is attached, the label may be peeled off after the attachment depending on the material of the other party's dust and the way of attaching. At the time of collection, garbage that is not labeled will of course not be collected, but it is claimed that it was peeled off for some reason after labeling it, but this is said. It is very difficult to argue because there is no rebuttal. This is a problem that often occurs on the part of the administrative side such as municipalities and the user side.

On the other hand, a label is provided with perforations to make it easy to tear, or a label base material of a relatively weak material is used, and when some external force is applied, the entire label is torn without peeling. Labels have been proposed that are devised so that at least a part of them will remain and serve as evidence. However, with such a label, it is very difficult to balance the original mission of having to be properly applied without damage and the tendency of tearing. It is too easy to tear, leaving only broken dust left behind, or peeling off the entire label because it is difficult to tear, resulting in the same problems as before.

In view of the above-mentioned problems of the prior art, the inventor of the present invention is unlikely to peel or break, but when peeled off, the traces that were pasted clearly remain on the pasting target, which proves evidence. As a result of earnest studies to provide a label of the present invention, the present invention has been achieved.

[0006]

The gist of a label according to the present invention is that a release agent layer is provided on a part of the back surface of a label base material on which characters and patterns are printed, and
The colored adhesive is applied to a part or all of the back surface side.

In particular, the release agent layer forms letters and patterns.

Further, in particular, characters and patterns are printed on the surface of the label substrate.

Furthermore, the separator is polymerized on the coated surface of the pressure-sensitive adhesive so that the space between the separator and the pressure-sensitive adhesive is more easily dissociated than the space between the release agent layer and the pressure-sensitive adhesive.

Alternatively, the surface of the label substrate on which letters and patterns are printed has a higher releasability than the release agent layer.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a label according to the present invention will be described in detail with reference to the drawings.

FIG. 1 schematically shows an example of a label according to the present invention. In the label 10, a release agent layer 14 is provided on a part of a back surface 15 of a label base material 12 on which letters and patterns are printed, and the back surface 15 side is colored by overlapping the release agent layer 14. The adhesive 16 is applied and configured. The release agent layer 14 is provided as characters, symbols, patterns, pictures, etc., but its shape and arrangement pattern are not particularly limited. The back surface 15 of the label base material 12 here means one surface of the label base material 12 on the side to which the adhesive 16 is applied, and the other one surface is called the front surface 13.

When the label 10 is once attached and then peeled off, the following characteristics are exhibited. That is, as shown in FIG. 2A, the label 10 is attached to the attachment object 18 and then peeled off.
As a result, as shown in FIG.
The pressure sensitive adhesive 162 in the portion where is disposed will surely remain on the side of the attachment partner 18. This is because the release agent layer 14 has a good releasability, so that the release agent layer 14 and the pressure sensitive adhesive 162 are more easily peeled off than the sticking object 18 and the pressure sensitive adhesive 162.

In this figure, all of the adhesive 161 in the portion where the release agent layer 14 is not provided is schematically shown to be peeled off together with the label base material 12. Depending on the material and surface condition of 18, the sticking object 18 may stick more strongly than the label base material 12, so that it is not always completely peeled off. However, if all of the adhesive 161 can be reliably removed, the release agent layer 1
Information such as characters and patterns drawn by 4 can be clearly left on the pasting object 18. For this reason, it is preferable that the back surface 15 of the label substrate 12 is provided with strong adhesiveness by, for example, corona treatment. In any case,
When the label 10 is once attached and then peeled off, a part of the colored adhesive 16 is surely left as a trace on the attachment object 18 side, so that it can be clearly determined whether or not it has been attached. The release agent layer 14 is the back surface 1 of the label substrate 12.
Since it is arranged only in a part of 5, the adhesive strength of the entire label 10 is not affected so much, and its adhesive strength is sufficiently secured.

If the surface of the pressure sensitive adhesive 16 is left open freely, it will stick to anything that it touches and is very difficult to handle. Therefore, it is preferable that the surface of the pressure-sensitive adhesive 16 is closed when it is transported or stored. In a preferred embodiment of the present invention, the label 10 is used by being polymerized with a separator. That is, as shown in FIG. 3, the separator 26 may be polymerized on the adhesive 16 side of the label 10 to form the label 20 with a separator.

When the label with separator 20 is used, the separator 26 is peeled off and the label 10 is used as it is. However, since the adhesive 162 on the release agent layer 14 provided on the label 10 is very easily dissociated,
It may come off together with the separator 26.
Therefore, the releasability of the separator 26 is controlled by the release agent layer 14
When the separator 26 is peeled off,
It must be ensured that the adhesive 162 remains on the label 10.

In another embodiment of the label with separator 20, the label 10 and the separator 26 are integrally manufactured. That is, as shown in FIG. 4, the release agent layer 14 and the pressure sensitive adhesive 1 are provided on the half of the back surface 15 of the label substrate 12.
6 is provided to form the label 10, and the release agent layer 2 is provided on the other half.
9 is provided to form the separator 26. Label substrate 1
2 is provided with perforations 27 between the label 10 and the separator 26. By folding the perforations 27 in two, the adhesive 16 of the label 10 as shown in FIG. A label 20 with a separator whose surface is covered with the separator 26 is obtained. At the time of use, as shown in FIG. 5B, the separator 26 may be peeled off to leave the label 10 bare.

Further, in another preferred embodiment of the present invention, the surface 13 of the label base material 12 is provided with a higher releasability than the release agent layer 14 and is used as a label superposing body or a label roll body. In these embodiments, since the separator is not used, there is an advantage that the labor of discarding the used separator can be saved.

FIG. 6 shows an example of the label superposed body 30. In the label superposed body 30, a plurality of labels 10 are arranged so that the surface 13 is in contact with the adhesive 16 of the adjacent label 10. 28 is overlaid. At the time of use, the labels 10 are peeled off one by one from the label superposed body 30 and used, but at this time, the adhesive 162 on the release agent layer 14 of the adjacent label 10 should not be peeled off together. Therefore, the releasability of the surface 13 of the label base material 12 must be higher than the releasability of the release agent layer 14.

The label 10 used as the label superimposing body 30.
7, it is convenient to provide a peeling portion 31 to which the adhesive 16 is not applied, at the end portion of the label base material 12, as illustrated in FIG. When the labels 10 are superposed, a gap is formed between the adjacent labels 10 at the peeling portion 31, so that the fingertip can be interrupted here and the labels 10 can be reliably peeled off one by one.

FIG. 8 schematically shows an example of the label roll body. The label roll body 40 is obtained by winding the strip-shaped body 34, to which the labels 10 are connected in series, in a roll shape with the label substrate 12 side facing the front side. Adhesive 16
However, since it is covered with the surface 13 of the label substrate 12, the handling becomes easy. Between the connected labels 10,
For example, a perforation 32 is provided so that the label 1 can be easily cut.
Separately use 0 one by one. Since the surface 13 of the label base material 12 is provided with a higher releasability than the release agent layer 14, the strip-shaped body 34 is smoothly removed without peeling off the adhesive 162 on the release agent layer 14 together. Can be withdrawn.

The material of the label base material 12 is not particularly limited. It may be opaque, semi-transparent, or transparent, and various materials such as cellophane paper, high-quality paper, art paper, kraft paper, and synthetic paper, cloth such as woven fabric and nonwoven fabric, and films made of various synthetic resins may be used. In addition, normally available tack papers, for example, SS quality tack paper, SS whitack paper, SS art tack paper, SS manufactured by Lintec Co., Ltd.
Glossak paper, high-quality tack paper manufactured by Oji Tack Co., Ltd., Marusho Chemical Industry Co., Ltd., and Tack Co., Miracoat Tack Paper, Whiltuck Paper, Art Tack Paper, etc. can also be used.

Characters and patterns are printed on the label substrate 12 according to the purpose of the label 10. For example, for waste trash, the name of the municipality to be collected or the type of trash is printed. Alternatively, if the product package is to be sealed, a company name, a product name, and a manufacturing number are printed. The printing may be performed on either the front or back surface of the label substrate 12, but is preferably printed on the front surface.

If the transparent or semi-transparent label substrate 12 is used, the label substrate 12 can be read through even if the back surface 15 is printed. However, if the printing color and the color of the pasting object 18 are similar, the contrast may be weakened and may be unclear, and it is difficult to use for the pasting object 18 whose color is not specified. On the other hand, the opaque label substrate 12
Clear characters and patterns can be printed on the surface without being influenced by the color of the pasting object 18. Label substrate 12
Each of the materials such as papers, cloths, films made of synthetic resin, and the like exemplified above includes opaque, semitransparent, and transparent materials. An appropriate material for the label substrate 12 is selected in consideration of strength, clearness of printing, cost, etc. according to the application of the label 10.

The release agent layer 14 is not particularly limited and various release agents can be used. For example, silicone resin,
Natural resins such as cellulose resin, alkyd resin, acrylic resin, polyurethane resin, polyester resin and varnish can be used. Particularly preferably, silicone resin, cellulose resin, acrylic resin or the like is used. These resins may be used alone or as a mixture with each other.
Further, in order to dispose the release agent on the back surface 15 of the label base material 12, various commonly used means such as coating, transfer and printing are adopted. It is also possible to adjust the release performance of the release agent by applying heat curing or photo-curing treatment after it is disposed on the back surface 15.

Further, as the adhesive 16, an ordinary adhesive or the like which has been used in a conventional adhesive label can be used. For example, a natural rubber-based or synthetic rubber-based adhesive, an acrylic resin-based adhesive, a polyvinyl ether resin-based adhesive, a urethane resin-based adhesive, or a silicone resin-based adhesive can be used. An acrylic resin-based pressure-sensitive adhesive is particularly preferable, but the pressure-sensitive adhesive used in the present invention is not limited to the types exemplified here.

The adhesive 16 may further include, if necessary, a tackifier such as a terpene resin or a styrene resin, a filler such as silica, calcium carbonate or barium sulfate, a softener such as a plasticizer, and an antioxidant such as anilide. You may mix | blend an agent, a crosslinking agent, etc.

Further, the adhesive 16 is colored. The coloring in the present invention has a broad meaning that it is not colorless and transparent, and includes each color obtained by mixing the three primary colors of red, blue and yellow, and black and white. The purpose of coloring the adhesive 16 is to make the adhesive 162, which remains as a trace after the label 10 is peeled off, stand out so that it can be easily found.

A pigment or dye is used for coloring. Examples of the inorganic pigments include white pigments such as zinc white and titanium white, black pigments such as carbon black, red pigments such as red pattern and red lead, blue pigments such as ultramarine blue and dark blue, and green such as chrome green and chromium oxide. Faces and the like are used, and examples of the organic pigments include insoluble azo dyes, insoluble dyes such as phthalocyanine, and lakes obtained by causing a metal compound to act on an aniline dye to precipitate. Examples of dyes include eosin, methylene blue, malachite
Green, methyl violet, etc. are used.

The method of applying the pressure sensitive adhesive 16 to the label substrate 12 is not particularly limited. For example, the method of dissolving the pressure sensitive adhesive 16 in a suitable solvent and coating it, or dispersing or emulsifying it in a suitable medium and coating it. And so on. When manufacturing the label 20 with the separator, the separator 2 is used.
Alternatively, a method may be used in which the adhesive 16 is first applied to 6 and the label base 12 on which the release agent layer 14 is disposed is attached.

The separator 26 is usually obtained by applying a release agent to the surface of the separator base material. Although the release agents exemplified for the release agent layer 14 described above can be used, a release agent having a releasability superior to that of the release agent layer 14 must be selected. Or a film of polyolefin such as polyethylene or polypropylene,
When a silicone resin film or the like is used as the separator base material, the separator base material itself is excellent in releasability, so that it can be used as the separator 26 as it is without adding a release agent. The release property higher than that of the release agent layer 14 is imparted to the surface 13 of the label base material 12 by applying the release agent or the like described above for the release agent layer 14.

Although the label according to the present invention has been described in detail above, the present invention is not limited to the above citations and examples, and the shape of the label, the characters and patterns printed on the label,
With respect to the material of the label substrate, the type and forming method of the release agent layer, thickness and pattern, the type and color of the adhesive, the coating method and coating amount, the configuration and material of the separator, etc., within the scope of the present invention. The present invention can be implemented with various improvements, modifications and changes based on the knowledge of those skilled in the art.

EFFECTS OF THE INVENTION According to the label of the present invention, since a part of the colored adhesive always remains in the trace of peeling, it is possible to clearly judge whether or not the label is attached. For this reason, if it is used for a fee-based label for waste disposal, it is possible to easily solve the problem of whether or not the label is attached. Moreover, since the release agent layer is provided only on a part of the back surface of the label base material, the adhesive strength of the entire label is sufficiently secured and it is not unnecessarily peeled off.

Further, according to the label of the present invention, it is possible to develop applications such as lottery by utilizing the pattern of the release agent layer. That is, if the release agent layer is formed in the shape of O or X, when the label is peeled off, the colored adhesive having the shape of O or X appears on the sticking partner and can be used as a lottery. Since the shape of the release agent layer can be arbitrarily selected, such as first or second grade, hit or deviate, A, B, C, etc., it can be used for an interesting application that has never existed before.

Further, according to the label of the present invention, by making the label base material transparent, it can be used as a sealed label which is not peeled off illegally. When the label of the present invention is peeled off once, the colored adhesive on the release agent layer surely transfers to the sticking partner, and conversely, a transparent pattern of the release agent layer is formed on the label. For this reason, even if this peeled label is attached to the original place again, a slight difference from the original position can be seen through the transparent label base material, so it is easy to see that it was opened once. Will be clear.
As a result, for example, it becomes possible to prevent illegal replacement of products in the sealed container. In addition, once peeled off, it becomes immediately apparent by visual inspection, so even if the customer illegally moves the label, such as when it is used to display the discounted price of the product, it can be easily found. Being able to do this will certainly prevent such fraud.

In particular, by printing characters or patterns on the surface of the label base material, it becomes possible to perform clear printing having a large contrast with the opaque label base material.

In particular, by using a label with a separator in which a separator is polymerized on the pressure-sensitive adhesive side, the tackiness of the pressure-sensitive adhesive can be suppressed and the handling can be facilitated.

Further, in particular, by imparting a releasing property higher than that of the release agent layer to the surface of the label base material, a label superposed body or a label roll body is formed, and stickiness of the pressure-sensitive adhesive is suppressed to facilitate handling. become able to. Since no separator is used, it is possible to save the trouble of discarding the used separator.
