Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a folding envelope in which its own sheets constitute the top sheet, bottom sheet and communication paper of the envelope.

Until now, there have been many inventions related to folding envelopes,
The stacked state of paper pieces after folding was limited to eight pieces.

This is because in conventional simple folding, the misalignment due to the thickness of the multi-layered paper was missed during folding, making it difficult to fold, and the edges were not aligned and the folded shape after folding was poor, making it difficult to weave. be.

In addition, in the case of folding envelopes with folding features, the address entry area on the top envelope and the exposed area on the bottom of the envelope are both on the same side of the original folding envelope form, so a large amount of notification information can be printed and written on the same side. Even if you want to fold the envelope, the bottom side of the envelope will inevitably be exposed to the outside after the envelope is configured, and the number of folded sides (
In addition, if there is a large amount of information to be written, it must be written on the back side, making it unsuitable for use in printing out variable information using printing machines such as electronic computing devices. there were.

Therefore, in this invention, the folding error of the envelope form can be easily avoided before the envelope is created, making it easier to fold, and the same side of the envelope form as the address writing side is all inside the envelope, increasing the efficiency of paper usage. To provide an envelope that is easy to seal after folding and easy to use after opening.

Next, an explanation will be given based on drawings showing embodiments of the present invention.

FIG. 1 shows an envelope form 1 used for making a folding envelope according to the present invention.

Further, a transfer section 10 having transfer holes 10 on both left and right end sides.
' is provided. In order to create the folding envelope of the present invention from this envelope form 1, address information is written on the upper left paper piece al, which is the address piece, on the surface of the upper left paper piece al, which is the address piece, in the continuous envelope form 1', in which the envelope form 1 is continuous, and on the surface of the other paper pieces at predetermined places.
After printing out the notification information using the printing machine of the electronic computing device, as shown in FIG. The transfer part 10' is cut off, and then the envelope form 1 is sequentially cut into individual units using a cutting device consisting of low hooves 13, 13, fast-rotating rollers 13', 13', and a blade 14.
When the paper pieces are transferred between the rollers 16 and 17 of the first tri-folding device 15, the lower parts of the paper pieces cl, c2, and c3 abut against the first stopper 2, bend and bend along the folding perforations 3, and the portions are bent. Bitten into the loaves 17 and 18, the lower three pieces of paper cl, c2, c3 and the middle three pieces of paper bl, b2, b3
Roller 1 is folded so that the surfaces of the rollers overlap each other.
7', 18', and the folding perforation 2 is formed by the rollers 17', 18', the roller 19, and the second stopper 20.
Along the middle three pieces of paper bl, b2, b3 and the upper three pieces of paper al,
The envelope form 1 is folded so that the back surfaces of a2 and a3 overlap each other, thereby folding the envelope form 1 into an S-shape.

In this state, the sheet of paper is folded without being affected by the thickness of other sheets of paper. Next, roller 2
1 and 21, and is transferred along the stop guide 22 to the rollers 24 and 25 of the second tri-folding device 23, the right end side of the three right paper pieces a3, b3, c3 abuts the third stopper 29, and the folding machine It bends and bends along the grain 5, and that part is bitten by the rollers 25 and 26, and the upper right paper piece a3 and the upper inner paper piece a2 are folded so that their surfaces overlap, and the rollers 25' and 26' and the loaf 27 are folded. The lower inner paper piece c is folded along the fold perforation 4 by the fourth stopper 29'.
2 and the lower left paper piece cl are folded so that their surfaces overlap, and thereby the envelope form 1, which was previously folded into an S-shape, is further folded into a Z-shape.

In addition, in this state, the paper thickness of the three paper pieces that were previously folded into an S shape is simply folded, and the misalignment of the folding is released to each end, so the influence of the paper thickness is extremely small. be. Next, by applying heat and strength, which are the bonding conditions for the adhesive 8 applied to the envelope form, using heat and pressure rollers 30 and 31, the periphery of the envelope 4 is adhesively sealed and a folded envelope 1'' is completed.

The recipient of this folding envelope 1'' is at opening perforations 6 and 7.
If the package is opened along the lines shown in FIG. 3, the package can be opened as shown in FIG.

In addition, in making the folding envelope of the present invention, a fourth adhesive is further added to the adhesive 8 of the envelope form 1 shown in FIG.
As shown in the figure, two paper pieces a2, a3 on the upper right side, inside the opening perforation 6 at the bottom of the back side, and two paper pieces b2, b on the right side in the middle.
3 At the top of the back, inside the opening perforation 6 and to the right of the middle 2 pieces of paper b2, b3 At the bottom of the surface, inside the opening perforation 6 and at the bottom right side 2 pieces of paper c2, c3 At the top of the surface, along the inside of the opening perforation 6, It is also possible to use an envelope form la coated with an adhesive 8' of the same quality as the adhesive 8, and the opened state of the envelope using this envelope form la is as shown in FIG. , c3 become continuous and easy to see.

2' and 3' are folding perforations.

Furthermore, the adhesive 8 applied to the sealing portion of the envelope form 1 described above may be applied to either one of the envelopes that overlap each other in the final folded form.

Further, in order to seal the envelope, an adhesive tape, adhesive tape, etc. may be adhered to the outer periphery of the opening perforation of the folded envelope. Further, the folding envelope of the present invention can be made from the above-mentioned envelope form in which the parts other than the transfer section 10' are rotated by 90 degrees.

In this case, the folding of the envelope form after printing is the same as described above, in the first Z-shaped or S-shaped fold, both of the two folding perforations in the same direction have opening perforations on both sides. The second folding is performed along a folding perforation orthogonal to the folding perforation.

Further, the opening perforations described above indicate opening locations, and may be formed by perforation or printing.

Note that the paper strips cl may be used as address strips; in this case, the upper three paper strips al, a2, a3 and the middle three paper strips bl, b2, b
3-6 Paper pieces around the surface 4 in the combined state and 2 paper pieces to the right at the bottom c2, c3 Around the surface 4 in the combined state and the middle paper piece b
2 pieces of paper around the back side 4 and the upper left side in the combined state of 6 paper pieces of l, b2, b3 and lower paper pieces cl, c2, c3
, A2 is formed by applying adhesives 8, 8 along the periphery of the back side 4 of the combined state, and the address information and notification information are printed on the surface of the CL and other pieces of paper at predetermined locations using a printing machine of an electronic computing device. After printing out, make horizontal fold perforation 2,
Fold so that the surface of CL, which is an address strip, is exposed from 3. Next, fold it so that the surface of CL, which is an address strip, is exposed from vertical fold perforations 4 and 5. A folding envelope may be obtained by applying the adhesive conditions 8 and 8 and sealing the periphery of 4.

As mentioned above, the folding envelope of the present invention is produced by printing a large number of notification items on the same side as the address display.
Not only is it very suitable for use with electronic computer printing machines, but it is very efficient in terms of paper usage and is very convenient, since the surface of the paper strips other than the address strips are located inside the envelope. Not only is printing on the front side suitable for many purposes, making it economical to print on envelope forms, but even more notifications can be sent if the back side is used for advertisements, promotions, etc. Ru.

In addition, since the envelope form is folded in an S-shape or Z-shape, the influence of the paper thickness is extremely small.The folded shape after folding is good, making it easy to seal, and the edges around the envelope are well aligned. It is very convenient to make everything from envelope forms to folded envelopes, such as the pre-made opening perforations do not shift, making it easy to open.

In addition, folding envelopes can be created without having other people's paper pieces mixed in with them, and various shapes can be obtained after opening, so each piece of paper can be used effectively depending on the purpose of use. statement, deposit statement,
This is a very useful folding envelope that can be used for a variety of purposes such as tax payment notices, transfer notices, and various reports.
