Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label protection seal for protecting characters and patterns printed on, for example, product labels and a method for manufacturing the label protection seal.

[0002]

2. Description of the Related Art Product names, designs, etc. are printed on a product label by a printing machine. These product names, designs, etc. do not easily come off or bleed, so special protection is required. do not need.

However, it is preferable to protect the manufacturing date and price printed on the label of the product when the product is shipped. This is because a thermal printer or inkjet printer is used to print the date of manufacture, etc.
Characters and patterns from these printers can be peeled off,
This is because it easily bleeds. Therefore, the coating liquid was applied to the label or the film piece was attached to the label.

[0004]

However, when the coating liquid is applied to the label, the characters or patterns printed on the label may be peeled off or smeared by the application of the coating liquid. Also, when sticking a piece of film on a label, put a larger film on the label,
After this, the film was punched out leaving the printed portion, but a die-cut roll for performing this punching had to be manufactured, and the cost for this was very high.

SUMMARY OF THE INVENTION An object of the present invention is to provide a label protection seal capable of reliably and inexpensively protecting characters and patterns printed on a label, and a method of manufacturing the same.

[0006]

In order to solve the above-mentioned problems, in the label protecting seal according to the present invention,
A plurality of protective sheet pieces are arranged on the back surface of the base sheet via a temporary adhesive layer, and an adhesive layer is applied to the back surface of these protective sheet pieces.

In the method for manufacturing a label protection seal according to another invention, a release paper is attached to a protection sheet via an adhesive layer, and the protection sheet is punched out to obtain the release paper. A plurality of protective sheet pieces are formed thereon, and a base material sheet is laid on each of the protective sheet pieces via a temporary adhesive layer.

[0008]

According to the label protection sticker of the present invention, since the adhesive layer is applied to the back surface of the plurality of protective sheet pieces, these protective sheet pieces are sequentially attached to, for example, a plurality of labels. You can wear it. After that, when the substrate sheet is peeled off from each protective sheet, each protective sheet remains attached to each label.

Further, according to the manufacturing method of another invention, each protective sheet piece is formed on the release paper via the pressure-sensitive adhesive layer, and the base sheet is temporarily adhered to each protective sheet piece. Since the layers are stacked via the layers, each protective sheet piece is sandwiched between the release paper and the base sheet. When this release paper is peeled off, the adhesive layer on one surface of each protective sheet piece is exposed. In this state, each protective sheet piece is sequentially attached to a plurality of labels, the base material sheet is peeled from each protective sheet, and each protective sheet is left attached.

A plurality of protective sheet pieces 3 are arranged via respective pressure-sensitive adhesive layers 4, and a base sheet 5 is superposed on these protective sheet pieces 3 via respective temporary adhesive layers 6. It

For example, a transparent synthetic resin sheet is used as each protective sheet piece 3, and another type of synthetic resin sheet is used as the base material sheet 5.

The temporary adhesive layer 6 is for temporarily adhering the base sheet 5 to each protective sheet piece 3, and firmly adheres to each protective sheet piece 3, and the base sheet 5 Is relatively weakly adhered to. As the temporary adhesive layer 6, various materials such as an ultraviolet curable adhesive and a thermosetting adhesive may be applied.

FIG. 3 shows a label sheet 8 in which a plurality of product labels 7 are lined up, and these product labels 7 are shown.
Are cut off one by one when attached to each product.
Each of these product labels 7 is provided with an entry field 7a for entering the date of manufacture. In the label protection sticker 1 of this embodiment, the intervals between the respective protection sheet pieces 3 match the intervals between the entry fields 7a of the respective product labels 7, and these protection sheet pieces 3 are used for the respective products as described later. The label 7 is attached to each entry field 7a.

Now, in the apparatus as shown in FIG. 4, the label sheet 8 is wound around the label sheet feeding roller 11, and is fed from this feeding roller 11, and the roller 12 → between the pressure contact rollers 13 and 14 → Laura 1
The sheet is conveyed along the route 5 and is wound around the label sheet winding roller 16. When the label sheet 8 is conveyed, the manufacturing date is sequentially printed by the printer 17 in the entry field 7a of each product label 7.

On the other hand, the label protection seal 1 is wound around the seal delivery roller 21 and is delivered from the delivery roller 21 as the label sheet 8 is conveyed. This label protection sticker 1 has a feeding roller 21.
The release paper 2 is peeled off during the transportation. The release paper 2 is taken up by the release paper take-up roller 23 via the roller 22. As a result, the adhesive layer 4 on the lower surface of each protective sheet piece 3 is exposed. In this state, the label protection seal 1 is conveyed along a route of the roller 24 → between the pressure contact rollers 13 and 14 → the roller 25.
During this conveyance, the protective sheet pieces 3 are sequentially pressed against the label sheet 8 via the pressure-sensitive adhesive layer 4 between the pressure contact rollers 13 and 14, and the protective sheet pieces 3 are sequentially transferred to the label sheet 8. To be glued. Along with this, the base material sheet 5 is wound around the base material sheet winding roller 18 via the roller 25.

Here, as described above, since the intervals between the respective protective sheet pieces 3 match the intervals between the entry fields 7a of the respective commodity labels 7, the respective protective sheet pieces 3 correspond to the respective commodity labels 7.
Will be adhered to the entry field 7a. As a result, FIG.
As shown in, each manufacturing date printed in the entry field 7a of each product label 7 is protected by each protective sheet piece 3.

As described above, in the above-mentioned embodiment, since each protective sheet piece 3 is adhered to the entry column 7a of each product label 7, the manufacturing date printed in the entry column 7a of each product label 7 You can surely prevent the sun from peeling or bleeding. Moreover, the work is relatively simple, and can be performed only manually without using the device shown in FIG. Moreover, it is not necessary to use a die-cut roll, and it can be realized at low cost.

By the way, as shown in FIG. 1, in the range of the protective sheet piece 3, a notch 26 surrounding the remaining portion 26.
It is also possible to form a on the release paper 2 in advance. in this case,
Peel off the release paper 2 and attach the protective sheet piece 3 to the product label 7
6A, a residual portion 26 remains between the protective sheet piece 3 and the product label 7 as shown in FIG.
As shown in (b), the protective sheet piece 3 can be rolled at the remaining portion 26. Roll it up and press, for example, a size to remove the remaining portion 26, and attach this portion to the product label 7
When pressed against, the protective sheet piece 3 protects the date of manufacture and the format. Therefore, the entry field of the product label 7 can be entered twice.

In the above embodiment, the protective sheet piece 3 is used.
Although a transparent synthetic resin sheet is exemplified as the material of the above, an opaque material may be used in some cases. For example, as shown in FIG. 7, the product label 27 is transparent, and the product label 2
When the manufacturing date (using the letters on the inside out) is printed on the back side of 7, the product label 27 is viewed from the front side even if the opaque protective sheet piece 28 is attached to the back side of the product label 27. Therefore, the protective sheet piece 28 does not get in the way. Since the protective sheet piece 28 is opaque, various materials can be used as the material, and for example, paper may be used.

Further, in the above-mentioned embodiment, the label protection sticker in which the rectangular protection sheet pieces are arranged in a row is exemplified, but the present invention is not limited to this, and the label protection seal may be selected depending on the shape and position of the portion to be protected. Thus, the label protection seal may be formed by appropriately arranging protection sheet pieces of various shapes. In addition to the label, the label protection sticker of the present invention can be applied as long as it has characters or patterns on which it is easy to peel or bleed.

Although the release paper 2 is used in the label protection sticker of the above-mentioned embodiment, instead of applying the adhesive layer on one surface of each protective sheet piece 3, an adhesive layer is applied,
The release paper 2 may be omitted. In this case, as shown in FIG. 8, each protective sheet piece 33 is arranged on the lower surface of the base material sheet 31 via the temporary adhesive layer 32, and the adhesive layer 34 is applied to the lower surface of these protective sheet pieces 33. It becomes the cross-section structure. The adhesive layer 34 is preferably one that melts in response to heat, light and pressure to generate an adhesive force. Further, here, since the temporary adhesive layer 32 is not separated for each protection sheet piece 33, when the protection sheet piece 33 is peeled off,
The temporary adhesive layer 32 is left on the side of the base material sheet 31. For this reason, the temporary adhesive layer 32 firmly adheres to the base sheet 31 and relatively weakly adheres to the protective sheet pieces 33, so that the temporary adhesive layer 32 adheres to the protective sheet pieces 33 relatively weakly. The material of is selected in advance.

Next, a method of manufacturing a label protecting seal according to another invention will be described.

FIG. 9 schematically shows a manufacturing apparatus to which an embodiment of the manufacturing method according to this another invention is applied. The manufacturing apparatus of this embodiment is for manufacturing the label protecting seal 1 shown in FIGS. 1 and 2.

In this manufacturing apparatus, the release paper 2 is wound around the release paper feed roller 41, and the release paper 2 fed from this is conveyed through the roller 42. A protective sheet 44 having one surface coated with an adhesive is wound around the protective sheet delivery roller 43. The protective sheet 44 delivered from here has a pressure-sensitive adhesive layer facing downward, Release paper 2 is conveyed through 45
Are overlaid on.

A UV curable ink, for example, is applied to the upper surface of the protective sheet 44 by the printing device 46 during the transportation, and the ink is dried by the drying device 47. After this, the protective sheet 44 is removed by the punching device 4
8 is punched out, thereby protecting sheet 44
Is divided into a plurality of protective sheet pieces 3 and the residue 49 of the other portion. The residue 49 is wound around the residue winding roller 52 via the roller 51. With the winding of the residue 49, a plurality of protective sheet pieces 3 remain on the release paper 2.

The UV-curable ink applied by the printing device 46 is used not only for printing but also as a temporary adhesive layer between each protective sheet piece 3 and the base sheet 5, so that these inks are used. Even when printing is not performed on the upper surface of the protective sheet piece 3, the colorless and transparent ultraviolet curable ink is applied. Further, as this printing, for example, there is a method of drawing the edge of each protective sheet piece 3.

Subsequently, the base material sheet 5 is superposed on each protective sheet piece 3 on the release paper 2. The base material sheet 5 is fed from the sheet feeding roller 53,
It is conveyed through rollers 54 and is stacked on each protective sheet piece 3. At this time, since the ultraviolet curable ink is interposed between each protective sheet piece 3 and the base sheet 5, the base sheet 5 is pressure-bonded to each protective sheet piece 3. As a result, each protective sheet piece 3 is sandwiched between the release paper 2 and the base sheet 5, and the label protective seal 1 is formed. The label protection sticker 1 reaches the sticker take-up roller 56 via the roller 55 and is taken up there.

[0028]

As described above, according to the present invention, the release paper is peeled off, and the protective sheet pieces are sequentially attached to, for example, a plurality of labels, so that the characters and patterns printed on these labels can be formed. It can be surely protected.
Further, since it is not necessary to use a die-cut roll, the cost can be relatively low.
