DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label without a backing sheet, and more particularly to a label without a backing sheet in which cuts are formed in a broken shape when peeled after pasting once.

[0002]

2. Description of the Related Art In general, a notch for preventing fraud (hereinafter referred to as a tamper cut) is formed on a discount display label of a product or a label attached to a large product to indicate that the product has been settled. If the label is once peeled off after being pasted, the label is avoided along the tamper cut, so that the label can be prevented from being replaced with another product.

[0003] A conventional label having a tamper cut is temporarily attached to a backing sheet, and is used after being peeled off from the backing sheet. Therefore, the conventional label has a drawback that the mount becomes garbage when used. Therefore, it is conceivable to apply a release material to the surface of the label, wind it into a roll, and use it as a label without a mount. After unwinding the desired length from the roll body, the label without the backing sheet is cut by, for example, a simple cutting device using a saw-shaped blade (see FIG. 7) and attached to a product. Can be

[0004]

However, the conventional label without mount has a drawback that when the label without mount is cut by a simple cutting device, the label without mount is broken by a tamper cut. For this reason,
A conventional label without a backing sheet had to be cut by a high-cost special cutting device such as an electric cutter.

The present invention has been made in view of such circumstances, and has as its object to provide a label without a backing sheet that can be cut in the width direction without being broken along the cut.

[0006]

According to the present invention, in order to achieve the above object, a release material layer is formed on a surface of a label substrate formed in a belt shape, and an adhesive layer is formed on a back surface of the label substrate. A cut is formed through the label base material, and is a mountless label that is peeled off in the form of a cut triggered by the cut when peeled off once attached, wherein the cut is 0.2 ~ 0.5m
It is characterized by being formed in micro perforations at m intervals.

[0007] According to the present invention, the cut is made 0.2 to 0.
Micro-perforations at 5 mm intervals (that is, fine perforations) prevent the label without backing paper from being torn due to the cut when it is cut in the width direction by, for example, a simple cutting device. That is, the label with no mount of the present invention can be cut in the width direction without being broken along the cut.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention without a backing according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a roll body 12 around which a label 10 without a mount is wound, and FIG. 2 is a sectional view taken along line 2-2 of FIG.

As shown in these figures, the label 10 without a backing sheet has a label base material 14, and a release agent such as silicone is applied to the surface of the label base material 14 to form a release agent layer 18.
Is formed, and the pressure-sensitive adhesive is applied to the back surface of the label substrate 14 to form the pressure-sensitive adhesive layer 16. As the label base material 14, for example, paper materials such as high-quality paper and coated paper,
Films such as PET (pet) film, synthetic paper, thermal paper, and the like are used.

On the surface of the label substrate 14, if necessary, print the product name, code, amount, date, company name, etc.
2 is given. Also, on the back surface of the label substrate 14, a detection mark 26 for detecting one unit of the label when the label with the backing is run by a label printer or an automatic attaching machine.
Is printed as needed.

The label 10 without a backing is formed with a cut 20 for cutting the label into units. The cutting notch 20 is formed, for example, by forming a perforation 20A in the width direction of the label 10 without the backing paper.
In some cases, through portions 20B are formed at both ends of the perforation 20A to facilitate separation. As a result, the label 10 without a mount is cut only by applying a shearing force to the label 10 without a mount along the cut 20 for cutting, and becomes a single leaf label 11 as shown in FIG.

The tamper-cuts 24, 24... (Corresponding to the cuts in claim 1) 24, 24. The tamper cut 24 is formed radially and penetrating through the label substrate 14 and the release agent layer 18. Further, the tamper cut 24 is formed between the cuts 20 for cutting. Therefore, as shown in FIG. 3, when the label 10 without the backing paper is cut into the single leaf labels 11 along the cutting notches 20, tamper cuts 24 are formed on all the single leaf labels 11. When the single-leaf label 11 is once adhered to an adherend (not shown) and then peeled off, the tamper cut 24 triggers the single-leaf label 11 to break.

The tamper cut 24 is formed in a micro perforated shape. That is, the tamper cut 24
As shown in FIG. 4, the release agent layer 18 and the label substrate 1
4 are cut alternately, and the uncut connecting portions 24B are formed alternately, and the length L1 of the cut portion 24A and the length L2 of the connecting portion 24B are 0.2.
It is set to about 0.5 mm. On the other hand, the perforation 20A of the cutting notch 20 includes a connecting portion of 0.5 mm or more and a cut portion of 1.0 mm or more. Therefore, when a shearing force is applied to the label 10 without a mount, the label 10 without a mount becomes the tamper cut 24.
The cutting notch 20 is cut before the cutting. Note that L
1 and L2, the thickness of the label 10 without the backing paper is 0.1 to 0.1.
In the case of 15 mm, it is preferable to set it to 0.2 to 0.3 mm.

Next, a method for manufacturing the label 10 without a backing sheet according to the present invention will be described with reference to FIGS.

FIG. 5 is a schematic structural view showing a manufacturing process of the label 10 without the backing paper. FIG. 6 is a sectional view of the label base material 14 in the course of the manufacturing process shown in FIG.

As shown in FIG. 5, a band-shaped label substrate 14 is wound around and mounted on the supply shaft 30.
From 0, the label base material 14 is unwound. Label base material 14
Are guided by a large number of guide rollers 32, 32, and print step 34, release agent applying step 36, die cut step 3
8. After passing through an adhesive application step 40, the sheet is wound around a winding shaft 42. Hereinafter, each step will be described.

The printing step 34 is a step of performing printing on the front surface or the back surface of the label base material 14 unwound from the supply shaft 30, and includes a plurality of printing units 44.
The printing unit 44 includes, for example, a plate cylinder 46, an impression cylinder 48,
It comprises a UV lamp 50, conveys the label substrate 14 while pressing the label substrate 14 between the plate cylinder 46 and the impression cylinder 48, and supplies an ultraviolet curable ink (an ink that is instantly cured by irradiation of ultraviolet rays) to the plate cylinder 46. Printing is performed on the label base material 14. Then, ultraviolet light is irradiated from the UV lamp 50 to dry the ink printed on the label substrate 14. As a result, as shown in FIG. 6A, printings 22, 22,... Are performed on the front surface of the label base material 14, and the detection marks 26 are printed on the back surface. In FIG. 5, a printing unit 44A is a unit that prints 22 on the front surface of the label base material 14, and a printing unit 44B is a unit that prints the detection mark 26 on the back surface of the label base material 14. This printing unit 4
The number of 4A and 44B is determined by the presence or absence of the detection mark 26,
It is changed by the number of colors of 2.

The release agent application step 36 is a step of applying a release agent to the surface of the label substrate 14 after the printing step 34. The type and release ability of the release agent are selected according to the type of the adhesive used in the adhesive application step 40 described later, and for example, a release agent such as silicone is used. This release agent
It is applied to the surface of the label substrate 14 by the coating unit 51, and is cured by irradiating ultraviolet rays from a UV lamp 52. Thereby, as shown in FIG. 6B, a release agent layer 18 is formed on the surface of the label base material 14.

The die cutting step 38 includes a release agent coating step 3
This is a step of forming a cut 20 for cutting and a tamper cut 24 in the label base material 14 that has gone through 6. The cut 20 for cutting and the tamper cut 24 are formed by, for example, pressing a bladed roll 54 called a die roll against the label base material 14 and rotating the same. As a result, FIG.
The label substrate 14 and the release agent layer 18 as shown in FIG.
Notch 20 and tamper cut 24 penetrating through
Is formed. In place of the bladed roller 54, a flat blade advances and retreats with respect to the label base material 14, and cuts 2 for cutting.
0 and the tamper cut 24 may be formed.

The pressure-sensitive adhesive coating step 40 includes a die cutting step 3
This is a step of applying a pressure-sensitive adhesive to the back surface of the label base material 14 after passing through Step 8. As the pressure-sensitive adhesive, for example, a hot-melt type (one using thermoplasticity), an emulsion type (one in which the pressure-sensitive adhesive is decomposed into water), a solvent-type (one in which the pressure-sensitive adhesive is dissolved in a solvent) and the like are used. The adhesive property of the adhesive is selected according to the type of the adherend. However, in order to prevent re-sticking, an adhesive having a relatively strong adhesive strength called strong viscosity, super-strong viscosity, or frozen viscosity ( For example, 500 g / 25 mm or more is desirable. It is also preferable to use an adhesive suitable for a wrap film containing polyolefin as a main component. Furthermore, the viscosity of the adhesive when applied to the label substrate 14 is
It is preferable that the pressure-sensitive adhesive does not exude onto the surface of the label substrate 14 through the cut 20 for cutting or the tamper cut 24. For example, 500 cps or more, preferably 3000 cps
It is good to be more than ps. When such an adhesive is applied from the coating nozzle 56 to the back surface of the label substrate 14, the adhesive does not exude to the surface of the label substrate 14, and the adhesive layer 16 is formed only on the back surface of the label substrate 14. (See FIG. 2).

The label substrate 14 which has passed through the adhesive application step 40
After the both ends are cut by a slitter 58 and cut to a predetermined width, the cut ends (scrap) 60 are wound around a scrap removal shaft 62, and the label base material 14 is wound around a winding shaft 42. Taken. As a result, the label 1 without the backing
Thus, the roll body 12 wound with 0 is manufactured.

According to the above-described manufacturing process, the roll body 12 of the label 10 without a mount can be manufactured without using a mount. Therefore, unnecessary mounts do not occur in the manufacturing process, and can contribute to resource saving.

Next, the operation of the label 10 without the backing sheet configured as described above will be described in detail.

FIG. 7 is a perspective view showing a cutting device 72 for cutting the label 10 without a mount in the width direction. As shown in the figure, the cutting device 72 has a simple structure, and has a saw-shaped blade 7.
4 is arranged upward, and the supply shaft 76 is rotatably supported. The roll body 12 of the label 10 without a mount is mounted on the supply shaft 76, and the leading end side of the label 10 without the mount is hung on the blade 74.

After unwinding the desired length of the backing-less label 10, the cutting notch 20 is aligned with the blade, and the leading end of the backing-less label 10 is pulled downward. As a result, a shearing force is applied to the cutting notch 20, and the label 10 without the backing sheet is cut in the width direction. At this time, the conventional label without mount may be broken by the tamper cut 24 and become unusable.

On the other hand, in the label 10 without the backing sheet according to the present embodiment, the tamper cut 24 is formed in a micro perforated shape, and is less likely to be cut than the cut 20 for cutting.
Even if the label 10 without a mount is cut along the cut 20 for cutting, it is not broken by the tamper cut 24. That is, the label 10 without the backing paper is
4, it can be easily cut to a desired length along the cutting notch 20 without being broken. As a result, an inexpensive cutting device 72 having a simple structure can be employed as the cutting means for the label 10 without the backing paper.

The label 10 without the backing sheet cut by the cutting device 72 is attached to a product. Once the attached label 10 without the mount is peeled off, the label 10 without the mount is torn along the tamper cut 24, so that unauthorized use such as replacement with another product can be prevented.

In the above-described embodiment, the cutting notch 20 is formed in the label 10 without the backing paper. However, even if the cutting notch 20 is not formed, the cutting device 72 shown in FIG.
Can be cut at a desired position.

Further, the cutting means for cutting the label without a mount 10 in the width direction is not limited to the above-described cutting device 72, and the necessary cutting force is applied to the cutting notch 20 to cut the label without the mount 10 in the width direction. What is necessary is just to cut into pieces. For example, the cutting device 78 shown in FIG. 8 is a bladeless type, and a cutting plate 80 is provided instead of the blade 74 in FIG. The cutting plate 80 has a top surface 80A coated with silicon and a corner 8 at the tip.
0B is formed. The cutting device 78 hangs the label 10 without a mount on the cutting plate 80, aligns the cut 20 for cutting with the corner portion 80 </ b> B, and pulls the leading end of the label 10 without the mount, thereby cutting the cut 20.
Is given a shearing force to cut the label 10 without the backing paper. Also in this case, the label 10 without the backing sheet can be cut in the width direction without being broken by the tamper cut 24 formed in a micro perforation.

Further, the cutting device 72 shown in FIGS.
An operator may manually cut the label 10 without a backing sheet in the width direction along the cut 20 for cutting without using the 78.
Also in this case, since the label 10 without the mount is cut along the cut 20 for cutting before the tamper cut 24 formed in the shape of the micro perforation, the breakage of the label 10 without the mount at the time of cutting can be prevented.

The shape of the tamper cut 24 is not limited to the above embodiment. For example, a plurality of tamper cuts 64 shown in FIG. 9 are formed in the width direction of the single leaf label 66 in parallel from the side edges toward the center. The tamper cut 68 shown in FIG. 10 is formed in a V-shape at the center of the single leaf label 70. These tamper cuts 64 and 68 are also the tamper cut 2 of FIG.
Similar to 4, by forming in a micro perforated shape,
It is possible to prevent the label without the mount 10 from being broken by the tamper cut 64 when the label without the mount 10 is cut.

[0033]

As described above, according to the label without the backing sheet according to the present invention, the cut (tamper cut) is set to 0.
Because it was micro-perforated at 2-0.5mm intervals,
When a label without a backing sheet is cut in the width direction by, for example, a simple cutting device, the label is not torn due to the cut. That is, the label with no mount of the present invention can be cut in the width direction without being broken along the cut.
