Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a paper for keeping contents confidential and a method for handling the paper.

(Background of the Invention) For example, to keep written information secret, it is sufficient to put it in an envelope and seal it, but the envelope can be opened and it is also possible to seal it again. Moreover, when the package is opened and resealed in a clever manner, it is difficult to know whether the package was actually opened or not.

The reason why the question of whether the package was opened or not is that it raises suspicions that the contents are not original and have been tampered with. Therefore, the conventional envelope structure cannot solve this problem.

Also, although postcards are a simple means of communication without worrying about other people's opinions, you may hesitate to use them if you want to keep them confidential. But 2
A letter made of two or more sheets of paper glued together on its entire surface is not a sealed letter, but can be used as a postcard if the size and other conditions meet the requirements.

(Technical Problem) The present invention was made with attention to the above-mentioned problems, etc., and its purpose is to form the contents so that they cannot be seen from the outside, and at the same time, to be able to fix the whole thing together by adhesive. To provide a secret document paper which cannot be restored once opened, and a method for handling the same.

Another object of the present invention is to provide a secret document paper having a structure in which the inner paper is covered with a transparent adhesive means when the package is opened, and a method for handling the same.

(Technical Means) The object is to have three parts corresponding to a front cover, a back cover, and a content sheet, which constitute a continuous paper body that can be folded with the content paper inside, and the paper body has a back side. The adhesive means has a contact means removably attached to the adhesive via a release layer, and the adhesive means has a transparency that allows the contents written on the surface to be seen through when attached to the surface of the content paper. This is achieved by a secret document paper that is characterized by:

In addition, this secret document paper is constructed by attaching transparent adhesive means to the release layer on the back side of the paper body, which has three parts corresponding to the front cover, back cover, and content paper. Folding the content paper inward by stacking the back side of the back cover on one side of the paper and superimposing the back side of the cover on the other side of the content paper and gluing them together by the adhesive means, and placing the content paper on the inside and both sides thereof. For secret type 1 paper that is folded so that the front cover and actual cover are located at the same position and fixed together with adhesive means, by peeling off the cover from the side, the adhesive means on the back of the cover is transferred to one side of the content paper. The desired purpose is achieved by opening the package.

(Example) Referring to the drawings, the secret document paper S of the present invention is shown disassembled in FIG. It is composed of an adhesive means 20 attached to the back surface by vacuum adhesion and a release paper 30 attached with an adhesive of the adhesive means 20.

The paper main body 10 is made of ordinary paper, synthetic paper, or any other material, and is formed into a horizontally long rectangular shape, for example, and has a release layer 14 formed on at least the entire back surface 10b.

The release layer 14 is obtained by impregnating the back surface of the paper body 10 with a known release agent, and is vacuum-adhered to one side of the adhesive means 20 and does not re-adhere once it is separated.

11 is a front cover, 12 is a back cover, and 13 is a content sheet. When the rectangular paper main body 10 is divided into several equal parts in the longitudinal direction, the outermost of the two sections located at the other end is the cover 11, The inner side is used for the back cover 12, and all other sections are used for the content sheet 13. In reality, the content paper is slightly narrower than the cover by the amount of oriwa.

A folding display 15 is provided on the front surface 10a of the paper body 10 to indicate the boundaries between the front cover 11, back cover 12, and content sheets 13+ and 132. Reference numeral 16 indicates other indications such as an indication of a postage stamp affixing location.

The adhesive means 20 is attached to the entire back surface of the paper body 10, and only one surface (lower surface in FIG. 2) of the carrier 23 made of a transparent film or sheet is coated with adhesive or pressure-sensitive adhesive. !
22 is formed. In addition to vacuum adhesion, the means for fixing the back peeling layer 14 of the paper main body 10 so that once it is peeled off, it cannot be re-adhered can be used, as well as a so-called double-sided adhesive tape and a base material to which it is attached. However, the adhesive properties of the tape itself remain. 21 is the opening guide section,
It is formed by roughening one side of the cover 1, and is provided as necessary.

The release paper 30 maintains the adhesive @f@22 of the adhesive means 20 until use.
It has a peeling layer 31 on the contact surface with the adhesive means 20 and is made of a material that can be peeled off from the adhesive means 20 and re-adhered.

Although the secret document paper of the present invention is constructed as described above, the composition, structure, material, and other conditions of each part can be arbitrarily changed within the scope of the purpose. Of course, the number of content sheets 13 can be freely increased or decreased from one to many sheets.

Handling method: When the release paper 30 is attached to the back surface 10b of the paper main body 10 via the adhesive means 20 (FIGS. 3 and 4)
, write the necessary matters on the contents sheet 13, and also make necessary entries on the front cover 11 and back cover 12, if necessary.

Next, remove all the peeling paper 30 and insert the inner paper 13+, 132.
, overlap the back side of the back cover 12 on the - side,
When cover 11 is superimposed on the other side of content paper, content paper 1
3. ．． 132, the back cover 12, and the front cover 11 are closely fixed together by adhesive means 20 (fifth
Fig. 6).

② To open the secret document 40 which has been sealed in this way, the adhesive means 20 is pressed in the state shown in FIG.
Only the front cover 11 is peeled off from the adhesive means 20, and then only the back cover 12 is peeled off from the adhesive means 20. At that time, the presence of the opening guide part 21 makes it easier to open the package. Then, the content paper 13 that was covered
Since you can avoid exposing both sides of the first sheet (Figure 7),
You can read the information written on the content sheet 13.

At this time, the surfaces of the inner sheets 131 and 132 are covered with the transparent carrier 23 of the adhesive means 20 left behind when the cover 11 was peeled off. Therefore, the content paper 13+, 13
The information written on the surface of item 2 can be clearly read and at the same time is protected from tampering.

■The secret documents shown in Figures 5 and 6 are all sealed in one piece, so use the M8 mailbox as shown, write the address,
If you put a stamp on it and mail it, it will be treated as a postcard.

(Operations and Effects) Since the present invention is constructed as described above, - once it is folded, the whole is fixed so that the contents cannot be seen from the outside, and when it is peeled off from that state, the peeled part is Since it cannot be re-adhered, it has the effect of inhibiting anyone who knows the structure from opening the package, and even if the package is opened, the information written on the contents paper cannot be tampered with unless the adhesive is removed. First, if the adhesive is removed, the surface of the inner paper will be damaged, so tampering is impossible.

Therefore, the present invention is most suitable as a paper for filling in matters and matters to be kept confidential, and can also be used for a wide range of purposes such as postcards, bank notices, driver's licenses and other license cards, identification cards, wills, etc. It has remarkable practical effects, such as being able to be used for
