Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an adhesive for preventing re-sticking, and is particularly suitable for use in, for example, price tags or labels for preventing re-sticking attached to openings of containers. This invention relates to an adhesive material for preventing repositioning.

(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, the adhesive paper pasted to the opening of a container to indicate its unopened status may be used, depending on the material of the opening of the pancage and its surface treatment method. It can be picked up and easily peeled off on the spot, and it can be reattached to prevent people from knowing that a foreign object has been mixed into the package. It is not possible to tell whether the package has already been opened or not. Therefore, there is a risk that the contents of the puff cage may be tampered with. For example, poisonous substances may be mixed into the sweets in the P7 cage.

Therefore, recently, adhesive films that can be easily peeled off after being applied have become available on the market.

FIG. 11 is a sectional view showing such an adhesive film.

This adhesive film 10 includes a film 12, and a silicon layer 14 is formed on a part of the back surface of this film 12. Then, metal is vapor-deposited on that surface ff16
is formed as. Therefore, a portion of this deposited layer 16 is not directly deposited on the film 12 due to the interposition of the silicon layer I4. Furthermore, the vapor deposition layer 16 and the release sheet 1-17 are temporarily attached with a pressure-sensitive adhesive layer 18.

This adhesive film 10 is adhered by peeling off the release sheet 17 and pressing the exposed surface of the adhesive N18 against an opening (not shown) of the pan cage.

Then, when the adhesive film 10 stuck to the opening is peeled off, only the portion of the vapor deposited layer 16' that was not directly deposited on the film 12 by the silicone layer 14 is adhered to the opening by the adhesive layer 18. A predetermined character such as ``opened j'' will appear depending on the remaining parts and peeled parts.Furthermore, if the opening part is opened, the vapor deposited layer 16' stuck there and remaining will be cut or removed. It will be torn open, which will tell you if it has been opened.

(Problems to be Solved by the Invention) However, in such an adhesive film 10, since the metal is vapor-deposited on the film 12 and the silicon layer 14,
The film used as the material to be vapor-deposited is limited to polyester or the like and must also meet various other conditions, which has the disadvantage of increasing costs. Also, film 1
When the adhesive layer 18 is peeled off together with the film 12, the exposed surface of the adhesive layer 18 that remains on the adhesive part of the material to be adhered becomes sticky and collects dust. The above also had problems. However, it was possible to reattach the film 12 due to the adhesive force of the exposed adhesive layer 18, making it impossible to achieve the intended purpose.

Therefore, the main object of the present invention is to provide an adhesive material that can be easily peeled off after application and does not require a vapor deposition process.

(Means for Solving the Problems) The present invention includes a first layer, a release layer laminated on the first layer, a second layer laminated on the release layer, and a second layer laminated on the release layer. An adhesive material comprising an adhesive layer laminated on a layer, where a is the force required to separate the first layer from the second layer at the release layer, and Adhesive force with material b
The adhesive material for preventing repositioning satisfies the following formula.

(Function) The adhesive layer provides adhesive strength to the adhesive material to adhere to the surface of the material to be adhered or the sealed portion.

The second layer retains its initial state when the first layer is removed.

The release 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 coating or the like, it can be produced without performing vapor deposition as in the prior art. Moreover, the second layer and the first layer are temporarily attached to each other through the release layer, making it impossible to reattach the label. Then, the first eyebrow peels off from the second layer and cannot be reattached, so it can be seen that the attached adhesive material has been peeled off. 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 adhesive material has been peeled off, and an adhesive material 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 adhesive material 10 of this embodiment is used as a label, etc., and as shown in FIG. 9, the adhesive material 10 is placed on the adhesive material 10A.
B is rolled up in a roll-down manner. Then, a release layer 14 is laminated on the surface of the surface layer 120 as the first layer, and a second layer is laminated on the surface of the release layer 14.
A resin layer 16 as a layer is laminated, and an adhesive layer 18 is further laminated on the surface of the resin layer 16. and,
A printing layer 24 is formed on the main surface of the surface layer 12, and further,
A second peeling layer 26 is formed on the surface of the surface layer 12 of the adhesive material 10A that is bonded to the adhesive layer 18 of the adhesive material 1'OB to be rolled up, and is subsequently formed in the same manner. Furthermore, a solid printing layer 23 such as full-print printing is formed on the main surface of the release layer 14 of the surface layer 12, and a printing layer 22 is also formed on the surface of the resin layer 16 on the adhesive layer 18 side. Therefore, the printing layer 23 increases the hiding power and makes it impossible to see through the printing layer 22 from the surface layer 12 side.
4. The coating film stability can be achieved.

However, the printing layers 22, 23, and 24 may not be formed.

The long strip-shaped adhesive material 1o is configured to have cuts 28 such as perforations at predetermined intervals so that it can be cut into predetermined strips.

The surface layer 12 is formed to prevent the resin layer 16 from being cut or torn, and the peeling layer 1
A resin layer 16 is temporarily attached through the resin layer 4. Examples of the surface layer 12 include paper 1 synthetic paper, cellophane,
Films such as polystyrene, polyester, aluminum foil, etc. can be mentioned, but when the adhesive piece 10a obtained by cutting off this adhesive material 1o is bent and attached to the sealing part, it resists the adhesive force of the resin layer 6. It is preferable to use a relatively flexible material that does not peel off when the surface layer 12 tries to restore its original state.

The peeling layer 14 is formed so that the resin layer 16 and the surface layer 12 can be easily peeled off in a state where they cannot be reattached, and is made of a peeling agent such as silicone resin, fluorine resin, or wax. is formed between the resin JEt16 and the surface N12.

The resin layer 16 is for, for example, sealing the opening of the package, and is also for opening the package by being cut or torn to create an unsealed state. This resin layer 16 is made of urethane resin or E
It is formed by coating the surface of the release layer 14 with a resin such as VA resin, PVA, vinyl acetate, acrylic, vinyl chloride, or nylon. Other examples of the resin layer 16 include a resin layer coated with a synthetic resin made by mixing metal powder with a synthetic resin and formed so that it can be cut or torn by applying a relatively weak force. can be given.

The adhesive layer 18 is for providing adhesive force to the adhesive piece 10a formed by the adhesive material 10 into a predetermined shape,
For example, the resin layer 1 is made of an adhesive such as a pressure-sensitive adhesive.
Formed on the surface of 6.

Note that this adhesive material 10 has a surface [12] where the force required to peel off the resin layer 16 with the release layer 14 is a, and the adhesive RIB is applied to a material to be adhered such as a package. The adhesive force with the adhesive material is b, and in the rolled adhesive material 10, among the adjacent adhesive materials 10A and IOB,
Adhesive material 1 with adhesive layer 18 of adhesive material 10B bonded thereto
Peel from the second peeling layer 26 of 0A! If the force required to separate the parts is C, then the force required to separate each part is expressed by the formula (<
It is configured to satisfy a<b.

To use, first, pull out the roll-shaped adhesive material 1o, peel it off from the adjacent adhesive material 10A and pull out a predetermined length, and then cut it into predetermined adhesive pieces 10a at cuts 28 such as perforations. The adhesive layer 18 allows, for example,
As shown in FIG. 10(a), it is pasted as a price tag or pasted on the opening of a candy package. Also, the 10th
As shown in Figures (b) and (C), when completely sealing the opening of the lid of a can or bottle, there is no need for cuts 28 such as perforations, and it is preferable to use a series of cuts 28.

In order to open the opening of the package to which the adhesive piece 10a consisting of the surface layer 12, the resin layer 16, etc. is attached, the attached adhesive piece 10a must be peeled off and the sealed portion must be opened. No. In this case, the surface layer 12
is weakly temporarily attached to the resin layer 16 via the release layer 14, while the resin layer 16 is attached to the opening of the package using adhesive JW18.
If you try to peel off the adhesive piece 10a, you can only peel off the surface layer 12, and the resin layer 16
remains stuck to the sealing part together with the adhesive jM18. Therefore, if the skin surface layer 12 is peeled off,
Since the surface layer 12 cannot be reattached to the surface of the resin layer 16 and does not return to its original state, it can be clearly seen that the package has been opened.

In order to completely open the opening of the package, the remaining resin layer 16 must be cut, torn, or peeled from the opening.

Note that even if the resin layer 16 is cut or torn at the same time when the surface N12 is peeled off to open the sealed portion, the unsealed state can be determined by looking at the state of the resin layer 16 in the same manner as described above.

In this example, the adhesive piece 10a was used for the package of sweets, but it was also used for the package of medicine and the envelope 1.
It goes without saying that it can be used as a part to be sealed, such as a bag, and as a price tag displaying the price.

Hereinafter, in order to further clarify the present invention, an explanation will be given based on an example of a method for manufacturing an adhesive material according to the present invention.

FIGS. 2 and 3 are illustrative views showing an example of an apparatus for manufacturing a laminate used in an embodiment of the present invention.

This laminate 30 has a release layer 14 and a resin N16 laminated in that order on the surface layer 12.

The device lOO includes a surface material 12 forming a strip-shaped surface layer 12.
It includes a holding roller 102 for holding a in a roll shape. One end of the surface material 12a held by the holding roller 102 is unwound and guided to the release agent coating device 104.

The release agent applicator 104 applies a release agent 1 such as silicone resin or fluororesin to one surface of the surface material 12a.
4a for printing and coating, and two rollers 1
04a and 104b. The lower part of the roller 104a is immersed in the release agent 14a stored in the pan 104c. Therefore, by rotating rollers 104a and 104b, the surface material 2 guided between them
A release agent 14a is printed and coated on the surface of 0a.

As the release agent coating device 104, a coating device such as a gravure roll coater, a reverse roll coater, or an air knife coater may be used, or a known printing machine such as an offset printing machine or a screen printing machine may be used. It's okay.

The surface material 12a coated with the release agent 14a is then led to a dryer 106 including, for example, a heater.

In the dryer 106, the release agent 14a printed and coated on the surface material 12a is dried and formed as the release layer 14. The surface material 12a on which the release layer 14 is formed in this way is
It is guided to a winding device 108.

Next, the roll-shaped surface material 12a wound on the winding device 108 is loaded onto the holding roller 102 of the release agent coating device 104 again. Then, in the same manner as described above, the peeled N
A second release layer 26 is formed by applying a release agent with a release force of 11, which is lighter than the release force of m14.

In this way, in this embodiment, the peeling force is made different on both sides of the surface material 12a. In other words, the release layer 14 has a heavier release force than the second GTT layer 26, but this may be achieved by, for example, varying the release force by varying the components of the release agent, or by changing the amount of the release agent applied. Make a difference by changing.

Then, the second peeling N26 is further formed, and the rolled surface material 12a is loaded into another resin 16a laminating apparatus 110 shown in FIG. 3.

Laminating device 110 includes two rollers 112 and 114. The lower part of the roller 112 is immersed in a resin 16a such as urethane resin or EVA resin stored in a pan 116. Thus, by rotating rollers 112 and 114, surface material 12 guided between them
A resin 16a is printed and coated on the surface of the release layer 14 of a. Then, the surface material 12 coated with the resin 16a
a is further led to a dryer 120 where it is dried and solidified. As a result, the surface of the release layer 14 on the surface of the surface layer 12 is coated with the resin 16a, and the resin layer 16
A laminate 30 is formed.

This laminate 30 is then sent to the next printing device 130. The printing device 130 is composed of a known printing machine such as an offset printing machine, and is provided on the transport path of the stacked body 30. The printing device 130 forms a printed layer 22 on the surface of the resin layer 16 with, for example, characters such as "opened" printed thereon. Also, for example, a predetermined line such as "opened" may be printed on the surface of the material to be adhered, such as a package, and when the surface layer 12 is peeled off, the lines formed on the material to be adhered may be printed through the resin layer 16. If the printed image line can be seen through, it is not necessary to form the printing layer 22.

Next, the laminate 30 is guided to a score forming device 136 that forms cuts 28 such as perforations for cutting. The cut forming device 136 has a cutting blade having a shape corresponding to the shape of the cut 28. A device including a blade roller or the like may be used.However, in the case of an adhesive material that does not form the cuts 28, it is of course not necessary to form the cuts 28 with the score forming device 136.

The laminate 30 with the printed layer 22 formed in this way is
It is wound up and held in a roll shape by a winding roller 140.

FIG. 4 is an illustrative view showing an example of an apparatus for further laminating an adhesive layer 18 using the laminate 30 shown in FIG. 3.

Apparatus 150 includes a coating device 152 .

The coating device 152 is for coating the adhesive 18a on the surface of the resin layer 16 of the laminate 30, and includes a main roller 154 and a roller 156 provided opposite to the main roller 154. The lower part of the main loaf 154 is immersed in the adhesive 18a stored in the pan 158, and the main loaf 154 is coated on the surface of the resin layer 16 of the laminate 30 sandwiched between the main roller 154 and the roller 156. Adhesive 18a is applied by roller 154.

The laminate 30 to which the adhesive 18a is printed and applied is
For example, it is led to a dryer 122 that includes a heater. In the dryer 122, the adhesive 18a printed and applied to the laminate 30 is
is dried to form an adhesive layer 18. and,
The adhesive material 10 formed by laminating the adhesive Fii 18 and the laminate 30 is guided to a take-up roller 160.

In order to make a label using the adhesive stamping die O manufactured in this manner, the laminate 30 may be loaded into a label manufacturing apparatus including a printing apparatus or the like.

In the embodiment described above, before forming the second peeling layer 26, a print [24] is formed by printing appropriate lines such as "product name" on the surface of the surface layer 12. However,
These printings N22, 23°24 may be formed alone or as a combination of two or more layers, or may not be formed at all.

Here, more specifically, it is as follows.

(1) Using a polyester film made by Toshi Co., Ltd. with a thickness of about 5 to 100 μ as the first layer, and using silicone resin ■ made by Toshi Co., Ltd. as a release agent to form release Fi14, after coating with a hardening agent. , and bake it with a dryer to form a release layer.

At this time, the force (C) required to peel off the adhesive layer 10 from the rolled up inner adhesive material 10 was 20 g. The thus constructed adhesive material was made into a label and affixed to a material to be pasted (paper, plastic, glass bottle, etc.). At this time, the adhesive strength (b) to the adhered material is 1,000
It was g. When I tried to forcibly remove the attached label from the material to which it was attached, the first layer of polyester film was peeled off first (see the margin below). Similar results were obtained when the urethane resin was coated as the second layer and the rest was the same as in the previous example.

(2) Use a nylon film made by Toshi Co., Ltd. with a thickness of about 5 to 100 μ as the first layer, and peel it off! Wax was applied as a release agent to form ttN and dried. Next, a second layer such as urethane resin or EVA resin is coated on the wax to a thickness of about 5 to 50 microns. At this time, the force (a) required to peel off the urethane resin or EVA resin from the wax surface was 100 g. A laminate of the film and the second layer thus prepared is coated with an adhesive manufactured by Toyo Ink Co., Ltd. to a dry film thickness of 5 to 5.
It was coated to have a thickness of 0μ. Thereafter, the laminate was rolled into a roll, and the force (C) required to peel off the adhesive portion from the second release layer was 20 g. The thus constructed adhesive material is labeled and attached to the adhesive material (
pasted on paper, plastic, glass bottles, etc.). At this time, the adhesive force (b) to the adhered material was 1.000 g.

When I tried to forcefully peel off the attached label from the material to which it was attached, the first layer of nylon film was peeled off first.

FIG. 6 is a sectional view showing another embodiment of the invention. In particular, the adhesive material 10 of this example differs from the example of FIG.
It is not formed by coating W14, but is superposed and bonded to the release layer 14 using the adhesive force of the adhesive layer 16b formed on the main surface of the resin layer 16.

The resin N16 is formed of a film made of a resin such as polyethylene, polypropylene, polystyrene, urethane, etc., and the adhesive layer 16b is formed of an adhesive 16b' having a weaker adhesive force than the adhesive layer 1.

FIG. 5 shows the surface layer 12, peeling M14 shown in FIG. FIG. 3 is an illustrative view showing an example of an apparatus for manufacturing a laminate 30 including a resin layer 16 and a resin layer 16. FIG.

In this device, unlike the device shown in Fig. 3,
In place of the laminating device 110 that coats the resin 16a, a laminating device 110' is provided that stacks and laminates the film 16' on the surface of the release layer 14 on the surface of the surface layer 12.

The laminating device 110' includes a device 117 that applies adhesive 16b' to the surface of the release layer 14 of the laminate 30, and a film 16.
It includes a device 118 for loading a roll of rolls. The adhesive applicator 117 includes a roller 112' and an adhesive 1.
After applying the adhesive 16b' to the surface of the peeling N14 of the laminated material 32 pulled out and guided from the supply device as the roller 112' rotates,
A film 16', which is separately looped from a device 118 for loading the rolled and stacked body, is overlapped and adhered to the surface of the adhesive 16b'.

In this way, the adhesive layer 16 is placed on the surface of the release layer 14 of the laminated material 32.
The laminate 30 in which the film 16' is laminated via b is as follows:
It is guided to a bonding device 119. For the adhesive device, when using an adhesive containing a water-soluble resin such as PVA, vinyl acetate, or acrylic, or a solvent-based adhesive such as vinyl acetate, urethane, or acrylic, as the adhesive 16b', When using a rubber-based or EVA-based hot melt adhesive, a "cooler" is used.

The laminate 3° in which the films 16' are stacked together to form the second resin layer 16 is then led to a score forming device 136 for forming perforations for cutting.

The cuts 28 are formed to divide a large number of identical arrays, and facilitate dividing the adhesive material 10 one by one.

The laminate 30 with the cuts 28 formed in this way is guided to the printing device 130, and an "opened" mark is appropriately marked on the surface of the resin layer 16.
The printing device 130 prints appropriate drawing lines such as the following, and the image is wound onto the winding roller 140.

Next, the laminate 30 thus wound around the winding roller 140 is loaded into, for example, an adhesive 18a applicator 158 shown in FIG. Similarly, adhesive 18a is applied to form adhesive layer 18.

Note that the adhesive 18a forming the adhesive layer 18 at this time
The same pressure-sensitive adhesive as in the above embodiment may be used, but a sheet-like adhesive material 10 as shown in FIG. 7 may be used.
When forming a pressure-sensitive adhesive, the adhesive will adhere inadvertently, so a rewetting adhesive that immediately dissolves when wetted with water and exhibits strong adhesive strength may be applied.

As this rewetting type adhesive, for example, a starch-based adhesive such as water-soluble polyethylene, PVA (PVA), or starch glue is used. In the case of such a single-leaf (sheet-like) adhesive material 10, unlike the adhesive material 10 shown in FIG. 6, the second release layer 26 is attached to the surface W12. The printed layer 24a may be formed by appropriately printing lines such as "product name" and "price j" on the surface N12 as shown in FIG. 7.

Furthermore, as shown in FIG. 7, the wide sheet-like adhesive material 10 is divided into a predetermined size by a widthwise cut 28a consisting of perforations and a lengthwise cut 28b, and the cut 28a By separating at 28b and 28b, the adhesive piece 10a of an appropriate size may be formed.

Further, as the adhesive 18a forming the adhesive layer 18,
A heat-sensitive type adhesive may be used, which has no tackiness on the surface at room temperature, but becomes activated and becomes adhesive when heated. As heat-sensitive adhesives, adhesives that are activated by heating, such as adhesives that are mainly made of heat-melting resin such as polyethylene and bond when cooled, may also be used. good. When applying such an adhesive to the surface of the resin layer 16, which is the second layer of the laminate 30, for example, a coating device as shown in FIG. 8 that applies the adhesive while heating it to an appropriate temperature is used. It is sufficient to apply it using 158,
The laminate 30 on which the adhesive 18a has been printed is introduced into a dryer 124 that includes a device for blowing cold air, and the adhesive 18a is dried to form the adhesive layer 18.
