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 have been known in which only characters and designs can be pasted onto objects.

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 attached to it are attached to the object along with the transparent film.When only the transparent film is peeled off, the stamped letters and designs appear. It has a structure in which it is attached to an object through an adhesive applied to itself.

A conventional method for manufacturing this kind of sticker is shown in FIGS. 9A and 9B to FIGS. 11A and 11B.

That is, first, a release paper 25 that has been subjected to release treatment is prepared, and then the colored film 2 is placed on top of it via an adhesive 26.
Paste 7.

Subsequently, as shown in FIG. 10A, cutting is performed using a cutting die (not shown) until the release paper 25 is reached and a cut 28 is made, and then the colored film 27 is cut out.
When it is removed, only the text remains on the release paper 25, as shown in FIG. 11A. Code 2 for this character part
Indicated by 9.

Subsequently, as shown in FIG. 12, a release film 31 is attached via an adhesive 30 that is weaker than the adhesive 26.

When in use, the release paper 25 is peeled off, the letters 29 are pressed onto the object via the adhesive 26, and the release film 31 is peeled off, leaving the letters 29 on the object side.

[Problems to be solved by the invention] However, Fig. 10 A and the corresponding Fig. 10 B
As can be seen from FIG. 11A and the corresponding FIG. Because it is coated with
When the colored film 27 is removed, a small space piece 29b remains on the release paper 25 side together with the letters 29, as shown in FIG.

This phenomenon occurs because the adhesive is also applied to the back side of the small piece 29b, and the small piece 29b
Even if a notch is formed to form the small piece 29b, the frictional force at the notch is large and the small piece 29b
This is because the area of the letter 29 is small, so there is a force acting on it that tends to remain with the letter 29.

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 with 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 performs screen printing for a mask except for the characters and designs on the release paper that serves as the mount, and then uses strong adhesive on top of it. A transparent film is attached via an adhesive, and then the desired characters and designs are printed on top of it by screen printing so as to overlap the printed area for the mask, and then a protective laminate film is attached via a strong adhesive. After pasting on the letters and designs, we used a cutting die that was slightly smaller than the letters and designs to cut out the paper until it reached the release paper, and then attached a transparent film on top of it using a weak adhesive.

[Function] The sticker obtained in this way has letters, etc. printed in the desired color on a transparent film coated with a strong adhesive, and parts other than the letters, etc., including the space surrounded by the strokes, etc. has no adhesive strength, so when the transparent film is pasted on an object and the transparent film is peeled off, only the punched letters, etc. remain on the object, and small pieces corresponding to the spaces of the letters, etc. Since it has no adhesion force to the object, it remains on the side of the transparent film coated with a weak adhesive, allowing only the punched characters to be affixed to the object.

Therefore, there is no need to remove small pieces of space such as characters as in the past, and mass production is possible, resulting in significant cost reductions.

[Example] Hereinafter, details of the present invention will be described based on an example shown in 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 and the ink of the mask layer 4a are fused and integrated into the adhesive 5.

Next, characters and designs are printed using green ink 14, for example, by screen printing while the paper is held between the upper and lower rollers 12 and 13.

Printing at this time is performed so as to overlap the printed portion for the mask.

Thereafter, a protective laminate film 17 is overlapped and bonded while being sandwiched between upper and lower rollers 15 and 16.

Subsequently, using a punching machine 18, characters and the like are punched out from the laminate film 17 until it reaches the release paper 1.

When punching out characters, etc., punching is performed using a cutting die 18a that is one size smaller than the characters, etc. that remain without screen printing, and a cut 18b is used.
form.

That is, if there is a completely surrounded space 8a in a part of the character 8 left unpainted when applying ink 4 by screen printing, for example, A, this space 8a is shown in FIG. 3A. As shown, the width is one width larger than the stroke width of the characters.

The size of the cutting die 18a of the punching machine 18, as shown by the solid line X in FIG. 6B, 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 18 to form the notches 18b, in the next step, a transparent film 19 is applied to the upper surface of the laminate film 17 with an adhesive 20 weaker than the strong adhesive 5.
is applied via rollers 21 and 22 and adhered by rollers 23 and 24.

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 are printed on the transparent film 1 to which the transparent film 11 is attached.
It's on the 9th side.

In this state, if the character 8 is pressed against the object together with the integrated transparent film 11 and transparent film 19, the background and the space 8a covered by the screen printing ink 4 will have no adhesive force. Therefore, it is not adhered to the object, and only the portion of the character 8 where the strong adhesive 5 is exposed is adhered to the object.

The transparent film 11 integrated in this state
When the transparent film 19 is removed, only the letter 8 remains on the object side as shown in FIG. 6, and the weak adhesive 2
The characters glued to the transparent film 19 side through the 0 are completely stuck to the object side.

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 19 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 corresponding to the desired characters or figures is screen printed on release paper, and a transparent film is adhered thereon using a strong adhesive. After printing desired characters and designs on top of the mask so as to overlap with the mask printing area, a protective laminate film is attached using a strong adhesive, and the characters and designs are printed from this laminate film until it reaches the release paper. The shape is cut using a cutting die that is one size smaller than the original, and then a transparent film is pasted on top of it using a weak adhesive, so the release paper can be peeled off and the letter side can be pasted onto the object. By peeling off the transparent film side, only the characters and designs with the spaces of the characters completely punched out can be pasted onto the 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.
