Description

[Detailed Description of the Invention] [Industrial Field of Application] The field of industrial application of the present invention is to attach it to an object together with a transparent film with the release paper removed,
This field relates to stickers that have a structure in which only letters and designs are affixed to objects when the transparent film is peeled off, and their manufacturing methods.

[Prior Art] Stickers that can attach only letters or designs to objects have been known for some time now.

Conventional stickers of this type consist of a release paper and a transparent film.The release paper is peeled off and the letters and designs pasted together with the transparent film are affixed to the object.When only the transparent film is peeled off, the punched letters and designs appear on the object. It has a structure in which it is attached to an object via an adhesive applied to itself.

A conventional method for manufacturing this type of sticker is shown in FIGS. 7A to 7D.

That is, first, a release paper 20 that has been subjected to release treatment is prepared, and a colored film 2 is applied thereon via an adhesive 21.
Paste 2.

Next, as shown in FIG. 7C, cutting is performed using a cutting die (not shown) until the release paper 20 is reached, making cuts 23, and then the colored film 22 is peeled off, as shown in FIG. 7D. Only the character portion remains on the release paper 20. This character portion is indicated by the reference numeral 24.

Subsequently, as shown in FIG. 9, a release film 26 is attached via an adhesive 25 that is weaker than the adhesive 21.

When in use, the release paper 20 is peeled off, the letters 24 are pressed onto the object via the adhesive 21, and the release film 26 is peeled off, leaving the letters 24 on the object side.

[Problems to be Solved by the Invention] However, as can be seen from FIG. 7C and the corresponding FIG. 8, and FIG. 7D and the corresponding FIG. 10, the notch 23 is not formed. Even if the adhesive is applied to the back side of the small piece in the space 24a surrounded by the strokes of the characters 24, when the colored film 22 is removed, the space will be removed along with the characters 24 as shown in FIG. The small piece 24b is the release paper 2
It remains on the 0 side.

This phenomenon occurs because the adhesive is also applied to the back side of the small piece 24b, and the small piece 24b
Even if a notch is formed to form the small piece 24b, the frictional force at the notch part is large and the small piece 24b
This is because the area of the letter 24 is small, so there is a force acting on it that tends to remain with the letter 24.

As a result, the characters end up in a pattern with crushed characters.

In order to prevent such crushed letters and designs from being stuck, in the past, small pieces located in the spaces of the letters and designs that had been punched out using a mold were manually removed using pins, etc. The method used was to remove the

Therefore, there were problems in that the work was extremely complicated, inefficient, and costly.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention uses screen printing for a mask on the surface of a release paper serving as a mount, excluding the intended pattern (including characters). A colored film for pattern formation is pasted onto the release paper containing this mask layer using an adhesive with strong adhesive strength, and a cutting die that is one size smaller than the mask layer is used to cut the colored film onto the release paper. The mold was cut out until it reached the desired size, and then a transparent film was pasted onto it using an adhesive with weak adhesive strength.

[Function] The stickers obtained in this way have screen printing applied to the strong adhesive layer in the spaces such as letters and designs, so they have no adhesive force and can be glued through a transparent film. After pasting it on the object,
When the transparent film is peeled off, only the punched letters and designs remain on the object side, and a small piece corresponding to the space remains on the transparent film side, making it possible to reliably attach only the punched letters to the object. .

Therefore, there is no need to remove small pieces in the space as in the conventional method, making it possible to achieve mass production and significantly reduce costs.

[Example] Hereinafter, details of the present invention will be explained with reference to the drawings.

FIG. 1 and subsequent figures explain the method of the present invention, and FIG. 1 shows the entire manufacturing process.

In FIG. 1, reference numeral 1 denotes a release paper that is continuously formed into a strip, the surface of which is subjected to a release treatment by applying silicone or the like.

Screen printing for a mask is performed on the release paper 1 using a pair of upper and lower rollers 2 and 3, except for the intended pattern.

The ink 4 used at this time is, for example, red,
The mask layer 4a formed by this ink 4 is a desired pattern, such as an alpha alphabet or a design character.

Next, an adhesive 5 containing a mask layer 4a made of ink 4 and having a strong adhesive force is applied to a pair of left and right rollers 6,
The adhesive is applied to the colored film 11 for character formation through the adhesive 7, and then the colored film 11 for character formation is overlapped with the strong adhesive being sandwiched between upper and lower rollers 9 and 10.

By the way, the mask layer 4a by screen printing
The forming process and the adhesion process of colored film 11 are performed in extremely close positions and in a short time;
Mask layer 4a is not dry.

Therefore, the adhesive 5, the mask layer 4a, and the ink are fused and integrated into the adhesive 5.

A pattern or the like is punched out from the colored film 11 by a punching machine 12 until it reaches the release paper 1.

When punching with this punching machine, ink 4
Punching is performed using a cutting die 12a that is slightly smaller than the pattern etc. formed by.

That is, if there is a space 8a surrounded by a part of the character 8 shown in FIG. As shown in FIG. 3A, the space 8a is formed to be one width W larger than the width of the strokes constituting the character.

The size of the cutting die 12a of the punching machine 12, as shown by the solid line X in FIG. 4B, is slightly smaller than the size of the character 8, which is not screen printed, and is shown by the dotted line Y.

Therefore, the space 8a is punched out so that it becomes smaller inward by the amount W mentioned above.

After being punched out by the punching machine 12 in this manner, in the next step, a transparent film 13 is coated with an adhesive 14 weaker than the adhesive 5 via rollers 15 and 16 on the upper surface of the colored film 11. It is pasted by a roller 17.

Since the sticker manufactured in this manner is continuous in the form of a band, the sticker is cut into a product by a predetermined number of characters using a cutter (not shown).

When using the thus obtained sticker, the release paper 1 is first peeled off. When the release paper 1 is peeled off, the punched characters (red in this example) are on the side of the colored film 11 to which the transparent film 13 is attached, with the colored film 11 as the background.

In this state, if the character 8 is pressed against the object together with the integrated colored film 11 and transparent film 13, the background and the space 8a covered by the screen printing ink 4 will not have adhesive strength. It is not adhered to the object, but only the part of the character 8 where the strong adhesive 5 is exposed is adhered to the object.

Colored film 11 integrated in this state
When the transparent film 13 is removed, only the letter 8 remains on the object side as shown in Figure 6, and the letters glued to the transparent film 13 side with a weak adhesive are completely stuck to the object side. be done.

At this time, the part corresponding to the space 8a is not attached to the object because it has no adhesive force, and remains on the transparent film 13 side, as shown in FIG.
Only the letter 8 with a completely punched out can be pasted.

At this time, a space where the letter 8 is punched out remains on the transparent film side as shown in FIG.

In this way, it is possible to obtain a sticker for attaching letters, etc. to an object while the space surrounded by the strokes of the text or design is reliably punched out, and it is possible to obtain a sticker for pasting letters, etc. It is possible to obtain a sticker that does not require any manual removal work.

[Effects] As is clear from the above description, according to the present invention, a mask layer is formed on a release paper by screen printing with the target pattern portion removed, and a mask layer is formed on the release paper while covering this mask layer. It consists of a colored film layer for forming a design that is adhered to the entire surface with a strong adhesive force, and a transparent film that is adhered to this colored film layer through an adhesive that has a weak adhesive force. The part from the film to the release paper is cut out using a die that is one size smaller than the printed part of the mask layer, so simply peel off the release paper, stick the text side to the object, and peel off the transparent film side. For example, it is possible to paste only characters or designs whose spaces have been completely punched out onto an object.

Therefore, it is not necessary to remove small pieces in the spaces between characters as in the past, and a sticker can be obtained at a low cost.
