Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealed letter which can be mailed as a type 1 fixed form mail without using an envelope and a method for manufacturing the sealed letter.

[0002]

2. Description of the Related Art Conventionally, as an envelope without using an envelope, as shown in FIG. 7, a plurality of sheets are superposed on each other and a plurality of sheets are attached to each other at four sides 51 to 54, and three sides 52 are formed. A sewing machine wire 55-57 for cutting is provided in the vicinity of the cutting board 54 through 54. The recipient of this letter is three sewing lines 55-57.
Can be used to cut off the peripheral edges of the envelope on three sides, and a plurality of sheets can be opened in the direction of the side 51 to read the information written inside the sheets.

[0003]

However, in such a sealed letter, the peripheral portion of the sealed letter must be cut along the three lines 55-57 of the sewing machine, which not only takes time to open the sealed letter but also the peripheral portion. At the time of excision, the portion separated from the perforation lines 55 to 57 may be torn, which may be unsightly, and eventually the information may be difficult to read. Also, a sealed letter like that in Figure 5
There is also a problem in that it is necessary to bond the peripheral portions of a plurality of sheets together and to form sewing lines for cutting on three sides, which takes time and effort to manufacture.

The present invention has been made in order to solve the above problems, and it is possible to easily close a seal without using an envelope and to easily and neatly open a sealed letter and its manufacture. The purpose is to provide a method.

[0005]

The envelope according to the present invention is
A4 size paper is folded in three and two sets of surfaces that overlap each other are removably adhered, and the address is written on one surface exposed to the outside. The A4 size paper may be formed by folding the A3 size paper in two and completely adhering to each other.

According to the method of manufacturing an envelope according to the present invention, a sheet of A4 size is folded in three, and a heat formed by two seals whose inner surfaces are preliminarily removably adhered to each other between two sets of mutually overlapping surfaces. This is a method in which the pressure-bonded sheets are respectively inserted, and the A4 size sheets folded in three are pressed and heated so that both surfaces of the thermocompression-bonded sheets are completely bonded to the overlapping surfaces. The A4 size paper may have folding sewing lines formed on both sides thereof, and may be folded in three in a Z-shape in cross section so that these folding sewing lines are ridge lines, or 2 sheets are formed on one side. It is also possible to form folding fold perforation lines of a book and fold each of these fold perforation lines into a ridge line to form a tri-fold. A half-cut sewing line may be used as the folding sewing line.
It is also possible to obtain an A4 size sheet by folding the A3 size sheet into two and completely adhering them together. In this case, if the A3 size sheet is folded in two and further half-cut sewing lines are formed in advance in all the portions that will be the ridges when folding in three, folding becomes easy.

Embodiments of the present invention will be described below with reference to the accompanying drawings. Embodiment 1 FIG. FIG. 1 shows an A4 size sheet 1 used for an envelope according to Embodiment 1 of the present invention. As shown in FIG. 1A, the surface of the sheet 1 is divided into planes A to A by dividing lines 2 and 3.
Paper C is divided into three equal parts, and as shown in FIG.
The back surface of is divided into planes D to F by dividing lines 4 and 5. Surfaces F to D are located on the back sides of the surfaces A to C, respectively. Folding perforation lines 6 and 7 are formed along the dividing line 2 between the surfaces A and B on the front surface of the sheet 1 and the dividing line 4 between the surfaces D and E on the back surface, respectively. A postal code field 8 is printed on the side A of the sheet 1 and a spread mark 9 is printed on the side D in advance. Folding sewing lines 6 and 7
For this, a half-cut sewing line that cuts through the sheet 1 to the middle portion of the thickness of the sheet 1 can be used. Such a half-cut sewing line can be formed simultaneously with printing when printing on the front surface and the back surface of the paper 1.

The name on the surface A of such a sheet 1 is changed to the surface B.
After printing or writing the communication text on C and C, respectively, as shown in FIG. 2, the folding sewing line 6 on the front side of the sheet 1 and the folding sewing line 7 on the back side are ridge lines, respectively.
That is, the paper 1 is folded in three in a Z-shape in cross section so that the surfaces B and C overlap each other and the surfaces E and F overlap each other.

Further, as shown in FIG. 3, the thermocompression bonding sheet 10 is sandwiched between the surface B and the surface C and between the surface E and the surface F, respectively. This thermocompression-bonding sheet 10 has two transparent seals 11 whose inner surfaces are preliminarily adhered to each other so as to be removable from each other.
The outer surfaces of the transparent seals 11 and 12 are adhered to the contact material and heated to a predetermined temperature so as to be welded to the contact material. Thermocompression bonding sheet 10
Is a size obtained by dividing the A4 size paper 1 into three equal parts, that is, slightly smaller than the sizes of the respective faces A to F so as not to protrude from between the faces B and C or between the faces E and F. It is formed small.

As described above, the paper 1 in which the thermocompression-bonding sheet 10 is sandwiched between the surface B and the surface C and between the surface E and the surface F is pressed by a heat sealer (not shown) and at a predetermined temperature or higher. By heating to 1, the both surfaces of one thermocompression bonding sheet 10 are completely bonded to the surfaces B and C, and the both surfaces of the other thermocompression bonding sheet 10 are completely bonded to the surfaces E and F. This produces a sealed letter.

The recipient of the sealed letter picks the lower end of the surface D on which the spread mark 9 is formed, peels the two transparent seals 11 and 12 of the thermocompression-bonding sheet 8 from each other, and separates the surfaces B and C from each other. By opening, the information displayed on these sides B and C can be read.

Printing on the surfaces A to C can be performed using a computer. Further, it is possible to print or write a communication message on the back side surfaces D to F. In particular, surface B
And C and surfaces E and F are overlapped and removably adhered to each other by the thermocompression-bonding sheet 10, so that confidential contents can be displayed on these surfaces. When the message is displayed on the surfaces E and F, the recipient of the sealed letter can open the surfaces E and F by pinching the lower end of the surface A on which the address is written. And the information displayed in F can be read.

An image may be printed instead of the communication text. In this case, the recipient of the sealed letter is the thermocompression bonding sheet 10.
When the two transparent stickers 11 and 12 are peeled off from each other and, for example, the faces B and C are opened, the face B on which the image is printed is
Since the transparent seals 11 and 12 are adhered on C and C, the image becomes clearer and more beautiful due to the laminating effect.

Instead of the heat sealer, the three-folded sheet 1 can be heated while being pressed by an iron.

Embodiment 2 In the above-described first embodiment, the sheet 1 is folded in three in a Z-shaped cross section, but as shown in FIG. 4, folding perforation lines 13 and 14 are formed along the dividing lines 2 and 3 on the surface of the sheet 1. However, as shown in FIG. 5, the folding perforation lines 13 and 14 may be folded into three folds so as to form ridge lines. In this case, the spread mark 15 is formed at the lower end of the surface B. In addition, it is also possible to write the address on the surface B of the central portion of the paper 1. Half-cut sewing lines can be used as the folding sewing lines 13 and 14.

Embodiment 3 The A3 size paper 21 is divided into six equal parts to divide the surfaces A to F, and a folding sewing line 22 is formed on the surface of the paper 21 so as to divide the paper 21 into two equal parts. The paper 21 is folded in two so that the folding sewing line 22 becomes the ridge line, and the back surfaces of the paper 21 are completely adhered to each other.
It is possible to obtain 4th version of the paper. The A4 size sheet thus formed is folded in three to manufacture the sealed letter as in the first and second embodiments. A half-cut sewing line can be used as the folding sewing line 22.

If the A3 size paper 21 is folded in two and half-cut sewing lines are formed in advance in all the portions that will be the ridges when the paper 21 is folded in three, folding of the paper 21 will be facilitated. That is, when forming the half-cut sewing line as the folding sewing line 22 on the surface of the paper 21,
A half-cut sewing line 23 is formed between the surfaces A and B, and a half-cut sewing line 24 is formed between the surfaces D and E, and the back surface portion of the boundary line between the surfaces B and C and the surface E are formed.
Half-cut sewing lines are formed on the back surface of the boundary line between F and F, respectively. These half-cut sewing lines can be formed simultaneously with printing during the printing process.

Further, an A4 size thermocompression-bonding sheet whose both surfaces are welded to a contact object by heating to a predetermined temperature is prepared, and after the paper 21 is folded in two with a folding sewing line 22, A thermocompression-bonding sheet of A4 size is inserted therebetween, and the thermocompression-bonding sheet 10 composed of two seals removably adhered between two sets of surfaces that are folded in three and overlap with each other as in the first embodiment. Insert each,
By heating the entire sheet of paper 21 while pressing it with a heat sealer or an iron, complete adhesion of the back surface of the sheet of paper 21 and releasable adhesion between two sets of surfaces that overlap each other can be performed at the same time.

As in the third embodiment, the A2 size sheet 2
By using No. 1, since the back side of the paper 21 is not used and the address and communication text are printed only on the front side, it is possible to print each side A to F at once using a computer or the like.

The paper 1 as described in each embodiment
Alternatively, if a series of folding and bonding processes of 21 are automatically performed using a general-purpose sealer, it becomes possible to easily and efficiently manufacture a sealed letter.

As described above, according to the present invention,
No need for envelopes, saving money. Further, since the address can be printed together with the communication text by using the computer, the address writing on the envelope is not necessary, which saves time and labor.
