Description

[Detailed description of the invention] [Industrial field of application] The field of industrial application of the present invention is to attach the release paper to an object together with a transparent film, and when the transparent film is peeled off, only letters and designs are left. This field relates to stickers that are attached to objects and their manufacturing methods.

[Prior Art] Stickers on which only letters or designs can be attached to objects have been known.

Conventional stickers of this kind consist of a release paper and a transparent film.The release paper is peeled off, and the letters and designs attached to it are pasted on the object along with the transparent film.When only the transparent film is removed, the stamped letters and designs appear. The design is attached to the object through an adhesive applied to the design itself.

The conventional manufacturing method of this kind of sticker is shown in FIG. 9(A).
(B) to FIG. 11 (A>, (B).

That is, first, a release paper 25 that has been subjected to a release treatment is prepared, and the colored film 21 is adhered thereon via an adhesive 26.

Subsequently, as shown in FIG. 10 (A>), 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 21 is peeled off.
As shown in FIG. 1(A), only the character portion remains on the release paper 25. This character portion is indicated by the reference numeral 29.

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. 11 (A) and the corresponding FIG. Colored film 27 is also coated with adhesive.
When it is removed, the 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 even if a notch is formed to form the small piece 29b, the I! I
F! This is because the force A is large and the area of the small piece 29b itself is small, so a force that tends to remain with the letters 29 acts on the small piece 29b.

Therefore, the pattern becomes a pattern in which the characters are crushed.

In order to prevent such crushed characters and designs from sticking, conventionally, small pieces located in the spaces of the characters and designs that have been punched out by a mold are manually removed using a bottle, etc. method was adopted.

Therefore, there are problems in that the work is 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 on a release paper that serves as a mount, excluding the text and design portions, and then uses strong adhesive on top of the screen printing. 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 is attached via a strong adhesive. After applying the film, we used a cutting die that was slightly smaller than the letters and designs to punch 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 thus obtained sticker has characters printed in the desired color on a transparent film coated with a strong adhesive.
Since there is no adhesive force in areas other than the letters, etc., including the space surrounded by the strokes, etc., when the transparent film is peeled off after being affixed to the object through the transparent film, only the punched letters, etc. will be visible. remains on the object side, and small pieces corresponding to spaces such as letters do not have adhesive strength to the object, so they remain on the transparent film side coated with a weak adhesive.
Only the punched characters can be pasted onto 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, the present invention will be described in detail based on the 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, and the mask layer 4a formed by this ink 4 has a desired design, for example, an alph? These include bets and designed characters.

Next, an adhesive 5 containing a mask layer 4a made of ink 4 and having a strong adhesive force is applied to the colored film 11 for forming characters through a pair of left and right rows 56. Colored films 11 for forming characters are stacked on each other while being sandwiched between upper and lower rollers 9 and 10.

By the way, since the process of forming the mask layer 4a by screen printing and the process of adhering the colored film 11 are performed in extremely close positions and in a short time, the 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.

Subsequently, characters and designs are printed using green ink 14, for example, by screen printing while being sandwiched between the upper and lower 0-lines 12 and 13.

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

After that, the protective laminate film 17 is overlapped and bonded while being sandwiched between the upper and lower rows 515, 16.

Subsequently, the laminated film 17 was cut using a punching machine F118.
Letters, etc. are punched out until the release paper 1 is reached.

When punching out the characters, etc., a cutting die 18a that is slightly smaller than the characters remaining without screen printing is used to form cuts 18b.

That is, if there is a completely enclosed 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 as shown in FIG. 3(A). As shown in the figure, the width of the strokes that make up the characters is one width larger than the width of the strokes that make up the characters.

The size of the cutting die 18a of the punching machine 18 is shown in Fig. 6 (
In B), the dotted line Y, as shown by aX, is formed one size smaller than the size of the character 8 shown without screen printing.

Therefore, the space portion 8a is treated so as to become smaller inwardly by the amount W mentioned above.

After being punched out by the punching t118 and forming the notches 18b in this way, in the next step, a transparent film 19 is applied to the upper surface of the laminate film 17 using an adhesive 20 weaker than the strong adhesive 5 via rollers 21 and 22. The film is applied by the rollers 23 and 24 while being applied.

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

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 on the side of the transparent film 19 to which the transparent film 11 is attached.

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 not have adhesive strength, so the object will become an object. 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.

If the transparent film 11 and the transparent film 19 that are integrated in this state are peeled off, only the character 8 will remain on the object side, as shown in FIG. The characters shown are completely attached 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 strength, and remains on the transparent film 19 side, and the space 8a is completely punched out as shown in FIG. Only the character 8 can be pasted.

At this time, the letter 8 is printed on the transparent film side as shown in Figure 8.
A punched out space remains.

In this way, the space surrounded by the strokes of characters and designs can be reliably punched out to obtain a sticker for pasting characters, 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 seal 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 design is cut out using a cutting die that is one size smaller than the design, 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 text side can be pasted onto the object. However, by peeling off the transparent film side, only the characters and designs with the spaces between 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 conventional method, and a low-cost sticker can be obtained.
