Description

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 which is cut so as to be broken when it is pasted on an object and then peeled off.

[0002]

2. Description of the Related Art In general, a notch (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 torn along the cut, so that it can be prevented from being replaced with another product.

A conventional label having a notch is temporarily attached to a backing sheet, and is used after being peeled off from the backing sheet. Therefore, there was a drawback that the mount became garbage after use.

[0003] The present invention has been made in view of such circumstances, and has as its object to provide a label without a backing sheet which does not require a backing sheet and which can be prevented from being replaced.

[0004]

In order to achieve the above-mentioned object, a feature of the constitution adopted in the present invention is that a cut for preventing cutting or re-pasting is formed in a label substrate of a label without a backing sheet.

[0005] Here, it is preferable that the cut for preventing re-placement is formed radially apart from the center of the label.

According to the above configuration, if the label is once peeled off after being pasted on an object, the label without the backing sheet is broken by the cut, so that the label can be prevented from being replaced and used.

[0007] In addition, since this release label has a release agent layer formed on the surface of the label base material and is wound in a roll shape, it is unnecessary to mount the release paper when it is unwound and cut off when necessary.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a label without a mount and a method of manufacturing a label without a mount 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 in 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 label 10 without a backing sheet is provided with a notch (hereinafter referred to as a tamper cut) 2 for preventing sticking.
4, 24... Are formed. Tamper cut 24
The label base material 14 and the release agent layer 1 are formed radially from the starting end which is separated from each other at the center of the label and located substantially on the same circumference.
8 and through. Further, the tamper cut 24 is formed between the cuts 20 for cutting. Therefore, as shown in FIG.
When 0 is cut along the cutting notch 20 into the single leaf labels 11, all the separated single leaf labels 11 have the tamper cut 24. When the single-leaf label 11 is once adhered to the adherend and then peeled off, the tamper cut 24 triggers the single-leaf label 11 to break.

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

FIG. 4 is a schematic structural view showing a manufacturing process of the label 10 without the backing paper. FIG. 5 is a sectional view of the label base material 14 in the course of the manufacturing process shown in FIG.

As shown in FIG. 4, a band-shaped label base material 14 is wound around and mounted on the supply shaft 30, and the label base material 14 is unwound from the supply shaft 30. 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 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, which conveys the label substrate 14 while pressing it between the plate cylinder 46 and the impression cylinder 48, and supplies an ultraviolet curable ink (an ink which 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. 5A, the prints 22, 22,... Are provided on the front surface of the label base material 14, and the detection marks 26 are printed on the back surface. In FIG. 4, a printing unit 44A is a unit that applies the print 22 to 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. 5B, a release agent layer 18 is formed on the surface of the label substrate 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.

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 dispersed in water), a solvent-type (one in which the pressure-sensitive adhesive is dissolved in an organic 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, ultra-strong, or frozen ( For example, 500g / 25mm
Above) is desirable. It is also preferable to use an adhesive suitable for a wrap film containing polyolefin as a main component.
Further, the viscosity of the pressure-sensitive adhesive applied to the label substrate 14 is preferably such that the pressure-sensitive adhesive does not exude onto the surface of the label substrate 14 through the cuts. For example, 500 cps
More preferably, it should be 3000 cps or more. 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 base material 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 (scraps) 60 are wound around a scrap removing 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.

The label 10 without the backing sheet manufactured as described above
After unwinding a predetermined length from the roll body 12 at the time of use, it is broken along the cutting notches 20 and attached to the adherend.

Next, the operation of the label 10 without the backing sheet configured as described above will be described with reference to FIG.

FIG. 6 shows a state in which the single-leaf label 11 of the label 10 without the backing sheet attached to the adherend is subjected to a “half price” printing 22 on the surface of the single-leaf label 11. I have. The single-leaf label 11 is attached only to a specific product (adherend), for example, when a time sale is performed in a retail store. Therefore, if the single-leaf label 11 is peeled off neatly and attached to another product, a great deal of damage will be incurred.

As shown in FIG. 6 (a), the label 10 without a backing sheet according to the present embodiment is
Is peeled off, for example, by pinching a corner portion, as shown in FIG.
As shown in (b), the single leaf label 11 starts to tear from the tamper cut 24. Then, as shown in FIG. 6C, the single leaf label 11 is peeled off in a broken shape.
Therefore, the single-leaf label 11 cannot be replaced with another product while keeping the original shape, and even if the single-leaf label 11 is replaced with another product, it is apparent from the change in the appearance of the single-leaf label 11 that the label has been incorrectly replaced. become.

As described above, according to the label 10 without a backing sheet of the present embodiment, since the tamper cut 24 is formed, the label 10 without the backing sheet once pasted cannot be replaced.

Since the label 10 without a backing sheet of the present invention is used by unwinding the roll body 12, the backing sheet is not generated as dust after use, and can contribute to resource saving. And, the label without the mount can be manufactured by the above manufacturing method.

The method for manufacturing the label 10 without the backing paper is not limited to the above embodiment. For example, the manufacturing process shown in FIG. 7 is different from the manufacturing process shown in FIG.
In the adhesive application step 40, an adhesive is applied to the release agent layer 18 side of the label substrate 14. Therefore, when the label substrate 14 is wound around the take-up shaft 42, the adhesive is transferred from the front surface side of the label substrate 14 to the rear surface side of the label substrate 14 which is superimposed on the outer circumference, and An adhesive layer 16 is formed on the back surface. In this way, the roll body 12 of the label 10 without the backing paper on which the tamper cut 24 and the cut 20 for cutting are formed can be manufactured similarly to the manufacturing process shown in FIG. In the case of this manufacturing method, the guide roll 7
2 is a non-adhesive processing of the surface.

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. 8 are formed in the width direction of the single leaf label 66 in parallel from the side edge to the center.
Single leaf label 66 on which the tamper cut 64 is formed
Also, similarly to the single leaf label 11 shown in FIG. 3, once it is pasted and then peeled off, it is torn from the tamper cut 64 to have a broken shape.

Further, in the above-described embodiment, as a method of cutting the label base material 14, a rotary type in which the bladed roller 54 is rotated to cut is adopted, but the present invention is not limited to this, and a flat die is adopted. May be.

Alternatively, thermal paper may be used as the label base material 14, and variable information such as numbers and bar codes may be thermally recorded by a label printer.

As described above, the label without mount of the present invention can eliminate the need for the mount while forming cuts (tamper cuts) and cutout lines for preventing sticking, so that the dust on the mount after use can be eliminated. Does not occur, processing costs are not required, and resources can be saved.
