Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a form paper for envelopes that is folded into three to form envelopes.

[Conventional technology]

BACKGROUND ART Conventionally, when financial institutions, service businesses, etc. send notification information to customers, a method has been adopted in which a sealed letter containing a piece of paper on which the notification information is printed is mailed to each customer. This envelope is often made of envelope form paper in which a top envelope sheet, an inner envelope sheet, and a bottom envelope sheet of the same size are connected through folding perforations. The customer's address is printed on the top of the envelope, and the notification information to the customer is printed on the inside of the envelope, and then the envelope form is folded in thirds and predetermined parts are glued to form the envelope. , when folded into three, the opening perforations made along the three sides of each piece of paper overlap at the same position, and by cutting out the three peripheries of this envelope from the opening perforations, it becomes possible to make a two-page spread. was.

The above-mentioned form paper for envelopes used to be printed in series with a printer, but in recent years, non-impact printers with excellent printing processing performance have been used, and as shown in Figure 3, form paper for envelopes a. It is also a single-sheet type in which a top envelope sheet b, an inner envelope sheet c, and a bottom envelope sheet d are consecutively arranged via folding perforations e and f, and is similar to the continuous form paper for envelopes. Form paper for envelopes is used, which has a sealing part g on the side of each piece of paper that faces each other when folded in three, and perforations h for opening. It was also possible to obtain a sealed letter by folding it into three using a combined folding machine.

As shown in FIG.
Five rotating rolls B ₁ to B ₅ arranged alternately in the conveyance direction, and a first blade part C and a second blade part arranged to face the upper two roll opposing parts on the insertion side. D, and to explain the operation of this folding machine A, an envelope form sheet a fed between rolls _B1 and _B2 is inserted into the first blade section C with the envelope sheet b at the tip, and hits the first blade section C. Then, envelope top paper B and envelope inner paper C are rolled from folding perforation e.
B ₂ and B ₃ are rolled up and folded together, and then the envelope form paper a is inserted into the second wing portion D with the folded envelope top paper b and envelope inner paper c as the tips, and when they collide, the envelope is folded. The inner sheet c and the envelope sheet d are rolled up between the rolls B ₃ and B ₄ from the folding perforation f and folded together. Then, the envelope paper form a, which has been folded into three, is fed between the rolls B ₄ and B ₅ while contacting the guide E, and is discharged.
Thereafter, by passing the paper through a pressure roller, the sealed portions g on opposite sides of each piece of paper adhered to each other, resulting in a sealed letter with all four sides sealed.

[Problem that the invention attempts to solve]

However, even when the envelope paper is inserted into the first and second wing sections, it continues to be fed toward the wing section by the roll. There was a problem in that the envelope was folded in at places other than the perforations, deteriorating the appearance of the envelope.

In addition, as mentioned above, the single-sheet form paper for envelopes has the same dimensions as the top envelope paper, inner envelope paper, and bottom envelope paper that are arranged in a row, so that it can be folded into three after passing through a folding machine. In this case, as shown in FIG. 5, for example, the sealing part g located on the side of the envelope sheet b is opposed to the sealing part g of the inner envelope sheet c located on the folding edge side when the two pages are spread. Therefore, if the sealing part is bonded with a pressure roll, the pressure roll i
There was a problem in that the folding perforation f was cut by the pressure, and the notification information printed on the inner envelope sheet c and the lower envelope sheet d was separated.

[Means for solving problems]

The present invention was created in consideration of the above-mentioned conventional problems, and involves folding together three pieces of paper: the top envelope sheet, the inner envelope sheet, and the bottom envelope sheet, which are connected through folding perforations. A form paper for forming an envelope by adhering a sealing part formed with an adhesive that is not normally attached to the sides of opposing pieces of paper, and of the above-mentioned upper envelope paper and lower envelope paper, At least the width of the top envelope paper and the width dimension of the adjacent envelope inner paper, when folded so that the back side of the top envelope paper and the back side of the inner envelope paper are facing each other, the width between the inner envelope paper and the bottom envelope paper. To solve the conventional problems by providing a form paper for envelopes, which is characterized by having a width dimension shorter than that of adjacent inner envelope sheets so that the upper envelope sheets do not overlap at the folding perforations located therein. It is.

[Effect]

In the present invention, even if the envelope paper with a small width dimension is inserted into the blade part with the top paper of the envelope at the tip, the envelope form does not wave inside the blade part, and the edge of the sealing part located on the side of the envelope top paper However, it becomes possible to apply the letter form to the pressure roller in a state where the edge of the envelope and the folded portion are shifted from each other without overlapping the folded portion of the envelope inner sheet and the lower envelope sheet.

〔Example〕

Next, the present invention will be explained in detail based on an embodiment shown in FIGS. 1 and 2.

1 in the figure is a form paper for envelopes, and the form paper 1 for envelopes is, as shown in FIG.
, an envelope inner sheet 3 and an envelope bottom sheet 4 are arranged consecutively through folding perforations 5 and 6.

Information such as the addressee's name and address are printed on the upper surface 2a of the upper envelope 2, and notification information for the customer is printed on the surfaces 3a and 4a of the inner envelope 3 and the lower envelope 4. Then, the envelope form paper 1 is hung on the folding machine as described above and folded into three (Z-fold) so as to hide the printed part of the notification information.
Then, a sealed letter is obtained by applying a pressure roll to adhere the sealing portions 7 located on opposing sides of each piece of paper 2, 3, and 4.

The above-mentioned sealing part 7 is formed by applying an adhesive that does not normally adhere to the sides of each piece of paper, but only becomes adhesive when it is pressurized (or heated). are the three sides of the back side of the envelope sheet 2 excluding the folding perforation 5 side, the three sides of the front side 3a of the inner envelope sheet 3 excluding the folding perforation 6 side, and the back side of the inner envelope sheet 3. They are provided on three sides excluding the folding perforation 5 side, and on three sides of the front surface 4a of the envelope sheet 4 excluding the folding perforation 6 side. Reference numeral 8 in the figure indicates an opening perforation made in each piece of paper. 8 are overlapped, and by removing three sides from this opening perforation 8, the sealed letter can be opened as a two-page spread.

In the form paper 1 for envelopes having the above structure, as shown in FIG. 1, the width R of the top envelope 2 and the bottom envelope 4 is smaller than the width S of the inner envelope 3, and When the paper 1 is folded into three to form an envelope, the edge of the sealing part 7 located on the side side of the upper envelope sheet 2 does not overlap the folding perforation 6, and the edge of the sealing part 7 located on the side side of the lower envelope sheet 2 does not overlap with the side edge of the lower envelope sheet. The edge of the sealing part 7 located at
The edge of the envelope and the folded part of the folding perforation 6 do not overlap, and the edge of the sealing part 5 of the envelope sheet 4 and the folded part of the folding perforation 5 do not overlap, and the folding perforations 5 and 6 do not overlap. Never broken.

In addition, the width dimension R of the upper envelope sheet 2 and the lower envelope sheet 4 is as follows.
Folding perforations 5 and 6 when folded into three
The edges of the sealing parts 5 and 7 do not overlap, and the sealing parts 5 and 7
The dimensions shall not impair the structure of the

Furthermore, even if the depth of the blade located on the upper insertion side of the folding machine is set to the width of two pieces of paper as before without any change, the upper part of the envelope
Since the width dimension of the envelope paper 3 is smaller than that of the envelope paper 3, when the envelope paper 1 is inserted into the folding machine, the envelope paper does not wave within the blade part, and the folding sewing machine can be used securely. It is designed to be folded in at eyes 5 and 6.

[Effect of idea]

As explained above, according to the present invention, the form paper for envelopes, which is a single sheet, consists of three pieces of envelope paper, the envelope top paper, the envelope inner paper, and the envelope bottom paper, which are connected through the folding perforations. A sealed letter is formed by folding the opposing pieces of paper together and gluing the sealing portions provided with an adhesive that is not normally bonded to the sides of each piece of paper, wherein the upper envelope sheet and the lower envelope sheet are bonded together. Of these, at least the width of the top envelope paper is determined by the folding perforation located between the inner envelope paper and the bottom envelope paper when folded with the back side of the top envelope paper and the back side of the inner envelope paper facing each other. In order to prevent the top sheet of the envelope from overlapping, the width of the inner sheet of the adjacent envelope is made shorter than the width of the inner sheet of the adjacent envelope, so there is room for the envelope sheet to move within the blades of the folding machine, and even if it bumps up against each other, it does not wave and is secure. The folding machine can be folded from the predetermined folding perforations without requiring changes to the folding machine. In addition, when folding into three, the edge of the sealing part of the envelope sheet that is glued to the folding side of the facing side does not overlap with the folding perforation, so the three-fold envelope form paper is placed on the pressure roll. However, due to the pressure applied to the three pieces of paper where the sealing part of the top envelope and the folding edges of the inner and bottom sheets of the envelope overlap, the folding of the inner and bottom sheets of the envelope close to these three pieces of paper will occur. The pressure applied to the part (i.e., the two pieces of paper) is reduced, and the folding perforation between the inner envelope sheet and the lower envelope sheet does not cut, and the facing side consisting of the inner envelope sheet and the lower envelope sheet is formed. This has excellent practical effects, such as printed notification information not being separated.
