Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tamperproof seal and a method for adhering it.

[0002]

2. Description of the Related Art Conventionally, in order to prevent contamination of poisonous substances such as medicines and foods, and to protect copyrights of recorded or recorded magnetic tapes, a sticker paper is attached to the packaging of sold products. Is proposed.

[0003] Then, a sealing paper to be attached to a product is coated with a colored adhesive on the entire back surface of the translucent film material as an adhesive surface.
The one having a set shape and a strong adhesive portion and another weak adhesive portion are preferably used on the adhesive surface.

[0004] Therefore, once the sealing paper attached to the product is peeled off, the set shape (usually, "open mark")
Or, it is set to a shape such as "a sales company mark". Only the part of the adhesive remains on the product for sale in an adhesive state, and the peeled paper wrapper has only the part having the above-mentioned set shape and the part to which the adhesive is not applied.

In other words, once the product for sale is opened, the translucent portion (setting shape) to which the adhesive is not applied is raised on the sealing paper, and the product cannot be sealed again after opening. Like

[0006] By the way, the above-mentioned paper seal is manufactured by some specialists, and in the work of sticking the paper seal to the product to be sold, the manufacturing process of manufacturing the product to be sold in a factory. This is done as part of the product packaging process.

[0007]

However, the sealing paper and the sticking method thereof, in which the adhesive is applied in a special shape as described above, have the following various problems.

That is, the paper wrapper having the above-mentioned structure is usually manufactured by some specialists because of the peculiarities of its manufacturing method, and when it is attached to a mass-produced product, it is manufactured. The cost is low, which is preferable, but on the other hand, when sealing a small-lot product, the production cost of the sealing paper is high, which is not suitable.

In addition, since the above-mentioned wrapping paper has an adhesive applied to the adhesive surface by a special method, it has a strong adhesive force even if the adhesive surface is slightly adhered to a portion other than the product. The adhesive adheres to other parts, making the paper seal unusable. In other words, the paper wrapper had to be handled carefully, which was inconvenient.

The present invention has been made in view of the above-mentioned conventional problems, and reduces the production cost of the sealing paper, the cost required for sealing, and moreover, it can be easily judged that the sealing paper has been opened. Another object of the present invention is to provide a method for adhering a paper wrapper.

[0011]

In order to solve the above problems, the wrapping paper according to the present invention is made of a film material that is thin enough to be easily stretched, and has a slit formed on the surface for damage at the time of peeling. At the same time, a strong adhesive layer is formed on the back surface.

The method for adhering a paper wrapper according to the present invention comprises a thin film material that can be easily stretched on the release surface of a release sheet having a release surface formed thereon.
In addition, a slit for breakage is formed on the front surface, and the back side of the sealing seal formed with a strong adhesive layer on the back side is overlapped and temporarily adhered to form a sealing seal tape, and the film material is attached to and detached from the back side. Sealing seal that can be easily adhered A band-shaped body on which a temporary adhesive surface is formed is used as a temporary adhesive tape, and the front surface of the sealing seal tape and the back surface of the temporary adhesive tape are pressed against each other to press the surface of the sealing seal to the temporary adhesive tape. The sealing seal is temporarily attached to the surface and the temporary adhesive tape with the sealing seal temporarily adhered is moved to a position facing the object to be sealed, and the sealing seal is pressed to the sealing position of the object to be sealed, and the strength of the sealing seal is increased. The adhesive layer adheres to the object to be sealed.

Further, as the temporary adhesive tape, the back surface is formed of a foam material, and the film material is temporarily adhered by the adsorbing force of the foam material, or the back surface of the temporary adhesive tape is charged with static electricity and the electrostatic attraction force of this static electricity is applied. Therefore, the one in which the film material is temporarily adhered is preferably used.

The term "thin enough to be easily stretched" means that it is stretched even if it is carefully peeled off with fingers or a tool. The strong adhesive layer is an adhesive layer having a strong adhesive strength such that it cannot be easily peeled off once attached, and the temporary adhesive surface is sufficiently weaker than the adhesive strength of the strong adhesive layer and the release sheet. It is stronger than the adhesive force between the adhesive sheet and the adhesive sheet and has an adhesive force such that the sealing seal can be peeled off from the release sheet by adhering and lifting with a temporary adhesive surface.

The sealing sticker is a sticker that is always attached to a position where the medicine, food, video tape or the like is to be opened when it is opened.

When the temporary adhesion is performed, the sealing seal tape and the temporary adhesive tape may be moved at a constant speed, or may be intermittently stopped.

Even when the sealing seal is adhered to the object to be sealed, the temporary adhesive tape and the object to be sealed are moved at a constant speed, or the object to be sealed is rotated in accordance with the movement of the temporary adhesive tape. Alternatively, it may be stopped intermittently during the bonding.

[0018]

The tamper-evident sealing sticker according to the present invention is adhered on the product package and is damaged when the product package is once opened.

If the sealing seal itself is peeled off, the sealing seal will be deformed due to the film material stretching or the slits formed on the surface of the film material will be broken and broken.

The method for adhering the sealing seal according to the present invention is as follows.
A sealing seal made of a film material that is thin enough to be easily stretched is temporarily bonded to the temporary sealing tape temporary bonding surface of the temporary adhesive tape, and then the sealing seal is bonded to an object to be sealed. That is, since the sealing sticker is attached to the object to be sealed without picking it with a finger or the like, fingerprints do not remain on the sealing sticker and the extremely thin film material is not damaged.

[0021]

[Embodiment] About tamper-proof sealing seal: Fig. 1 shows a sealing seal 1 according to the present invention. As shown in Fig. 1, the sealing seal 1 includes a main body a and a lid of an object to be sealed, for example, a box-shaped object. The box-shaped material A is sealed by being attached to the joint with b.

As shown in FIGS. 2 and 3, the sealing seal 1 forms a sealing seal tape 6 by temporarily adhering to the peeling surface 5a formed on the surface of the strip-shaped release paper 5 at a set interval. The release surface 5a is the release paper 5
It is preferably formed by applying a silicone resin to the surface of the.

The sealing seal 1 has a rectangular thin film material 2 having slits 3 formed on the surface for damage during peeling, and a strong adhesive layer 4 coated with an adhesive B having strong adhesiveness on the back surface. Has been formed.

The film material 2 is a thin film that can be easily stretched. This is a seal sticker 1
A polypropylene film having a thickness of about 12 μ to 16 μ is preferably used because the film material 2 can be stretched even if it is pulled with a finger to peel off the film. Also,
For this film material 2, a mark indicating the responsibility of the sealing, a product description such as that the product cannot be returned once opened, or the duplication of the sealing sticker is prevented. It is also possible to put a tint block.

On the other hand, the slit 3 formed on the surface of the film material 2 is formed so as to be divided into two or more parts when the sealing seal 1 is peeled off. To be done. The depth of the slit 3 is so deep that it does not penetrate the film material 2. Therefore, even if the sealing seal 1 is once opened or if it is attempted to be peeled off illegally, the sealing seal 1 is torn in the middle and cannot be reused.

Adhesive B applied to the back surface of the film material 2
Has an adhesive force capable of adhering the sealing seal 1 to the adherend A sufficiently strongly.

A method of manufacturing the sealing seal 1 formed as described above will be described below.

First, on the entire release surface 5 a of the release paper 5,
A film material 2 having the same shape as the release paper 5 is laminated. The back surface of the film material 2 is coated with the adhesive B having a strong adhesive force over the entire surface, and the film material 2 is separated from the peeling surface 5a.
Is temporarily adhered to.

Next, on the surface of the film material 2 laminated on the peeling surface 5a, an outer shape cut line 7 which is a model of the outer shape of the sealing seal 1 and a lightning-shaped slit 3 for damage at the time of peeling are inserted (FIG. 4).

Then, the unnecessary portion 8 of the film material 2 located outside the outer shape cut line 7 is peeled and removed together with the strong adhesive layer 2 (see FIG. 5).

As a result, the sealing seal 1 remains on the release surface 5a of the release paper 5, and the temporary adhesive tape is formed.

The design of the sealing seal 1 according to the present invention can be changed appropriately.

For example, as shown in FIG. 6, when the slit 3 of the sealing seal 1 is pulled for improper peeling by making the width different between the peripheral portion and the central portion, the amount of expansion is different. The two-dot chain line in the figure indicates the joining line between the main body and the lid.

The sealing seal 1 shown in FIG. 7 is provided with a slit 3 so that the sealing seal 1 can be easily torn in the middle if the sealing seal 1 is to be peeled off by mistake.

Regarding the method for adhering the sealing seal 1: Next, the method for adhering the sealing seal 1 according to the present invention will be described.

FIG. 8 is a perspective view showing an example of an apparatus for carrying out the method for adhering a sealing seal according to the present invention, in which the sealing seal 1 is attached to the mating portion of the box-shaped main body a and the lid b. The case is shown. FIG. 9 is a partially enlarged front view of FIG.

The leading end of the sealing seal tape 6 wound around the sealing seal tape supply drum 11 is guided to the sealing seal peeling member 12 via a sealing seal tape guide roller 17 which is rotatably supported.

As shown in FIG. 9, the sealing seal peeling section 12 comprises a peeling guide base 12a and a temporary adhesive tape pressing base 12b. The peeling guide 12a has a sharp end 12
c is formed, and the temporary adhesive tape pressing base 12b is biased by the spring 19 to the acute angle end 12c of the peeling guide base 12a. The sealing seal tape 6 guided from the sealing seal supply drum 11 has the acute-angled end 12a.
Then, the sheet is folded back and wound around the release paper winding drum 13 via the release paper guide roller 18.

The release paper take-up drum 13 is rotatable by a drive device (not shown) with the shaft 13a as a drive shaft.

The temporary adhesive tape 14 is composed of an endless belt-shaped body, and the back surface 14a is formed of a foam material having a minute suction cup shape. The temporary adhesive tape 14 is temporarily adhesive tape guide rollers 15a, 15b, 15c rotatably provided by a driving device (not shown).
It is bridged over and draws an endless orbit. This temporary adhesive tape 14
The foamed material on the back surface 14a of the above is urged by the temporary adhesive tape pressing base 12b of the sealing seal peeling portion 12 to the surface of the sealing seal 1 of the sealing seal tape 6 guided on the peeling guide base 12a. The foamed portion of the foamed material functions as a suction cup, and the back surface 14a of the temporary adhesive tape 14 is adsorbed on the front surface of the sealing seal 1.

The sealing seal pressing device 16 is a sealing seal 1 that is temporarily adhered to the back surface 14a of the temporary adhesive tape 14.
Is attached to the object to be sealed A, and is composed of a drive device 16a, a drive shaft 16b, and a pressing base 16c. By operating the drive device 16a, the drive shaft 16b reciprocates, and the pressing table 16c attached to the tip of the drive shaft 16b reciprocates.
That is, the surface 14b of the temporary adhesive tape 14 is pressed onto the pressing base 16c.
Then, the back surface (strong adhesive layer 2) of the sealing seal 1 that is temporarily bonded to the back surface 14b of the temporary adhesive tape 14 is pressed and bonded to the sealed object A.

The operation of the sealing sticker sticking device 10 constructed as above will be described below.

When the sealing sticker attaching device 10 is activated, the release paper winding drum 13 rotates, and the sealing sticker tape 6 wound around the sealing sticker supply drum 11 is
The release paper winding drum 13 is sequentially wound up.

At the same time as the above, the temporary adhesive tape guide rollers 15 rotate, and the temporary adhesive tape 14 rotates in an endless track.

The sealing seal tape 6 pulled out from the sealing seal supply drum 11 is passed through the sealing seal tape guide roller 17 and the sealing seal peeling section 12 is provided.
Will be guided to.

As shown in FIG. 9, the sealing seal tape 6 guided to the sealing seal peeling section 12 is peeled off by the peeling guide 12a and the sealing seal 1 is peeled off.
The sealing sticker 1 is temporarily adhered to the back surface 14a of the temporary adhesive tape 14 by the pressing force of the temporary adhesive tape pressing base 12b which is urged from above the temporary adhesive tape 14.

The sealing seal 1 temporarily adhered to the back surface 14 a of the temporary adhesive tape 14 is the temporary adhesive tape 14 as it is.
Along with the movement of, the sealing seal pressing device 16 is moved.

When the sealing seal 1 is located directly below the sealing seal pressing device 16, the pressing base 16c of the sealing seal pressing device 16 moves downward and presses the surface 14b of the temporary adhesive tape 14. As a result, the back surface (strong adhesive layer 2) of the sealing seal 1 that is temporarily adhered to the back surface 14a of the temporary adhesive tape 14 is pressed and adhered to the sealed object A.

In this way, once the sealing sticker attaching device 10 is activated, the sealing sticker 1, which is temporarily adhered to the sealing sticker tape 6 at the set intervals, is sequentially adhered to the object A to be sealed.

The method of adhering the paper wrapper according to the present invention is not limited to the above-mentioned embodiment, and can be changed as appropriate.

For example, the back surface 14a of the temporary adhesive tape 14 is preferably made of a foam material.
4 may be a smooth film material. That is, when the temporary adhesive tape 14 is made of a film material, the film material moves to cause friction with the temporary adhesive tape pressing base 12b urged by the film material to generate static electricity on the film material. Then, the sealing sticker 1 can be temporarily adhered by the electrostatic attraction.

The shape of the pressing table 16c is determined according to the shape of the object A to be sealed.

Further, the sealing seal 1 for the sealing object A
When adhering, the object to be sealed may be sealed while moving the object to be sealed at a constant speed with the temporary adhesive tape.
When the object is a cylindrical object, the object may be sealed by pressing the sealing seal while rotating the object to be sealed.

[0055]

The tamperproof seal according to the present invention is
Since it is made of a thin film material that can be easily stretched, and a slit for breakage is formed on the front surface and a strong adhesion layer is formed on the back surface, once it is adhered to the object to be sealed. However, it is impossible to peel off this sealing seal without damaging it.

That is, when the film material is pulled to peel off the sealing seal, the film material is deformed and the shape of the sealing seal is changed. Even if the film material could be peeled off without being deformed, the slits formed on the surface of the film material would cause the film material to be divided into small pieces and damage the wrapping paper.

Therefore, once the packaging of the product is opened or the sealing sticker is peeled off, the sealing sticker is deformed or dismembered, and it can be confirmed at a glance that the product has been opened.

Further, since the sealing sticker has only the strong adhesive layer formed on the back surface of the film material, for example,
Even when applying an adhesive to form a strong adhesion layer,
It is not necessary to apply this by a special method, and the production cost of the sealing seal can be reduced.

In the invention according to claim 2, after the sealing seal tape is temporarily adhered to the temporary adhesive tape, the sealing seal temporarily adhered to the temporary adhesive tape is moved to a position facing the object to be sealed, Since the sealing seal is pressed to the sealing position of the sealed object and adhered by the strong adhesive layer, the sealing seal is made of a thin film that can be easily stretched and has a strong adhesive layer on one side. In addition, it can be adhered to the object to be sealed cleanly.

In addition, since it is not necessary to pick up the sealing seal with each finger and to bond the sealing seal to the object to be sealed, it is possible to suitably perform a large amount of sealing.
