Description

The present invention relates to a folded envelope obtained by folding a sheet of paper, which enables a large amount of information to be transmitted and is developed in various three-dimensional states after opening, which is of interest to the recipient and a method for manufacturing the folded envelope.

Conventionally, as a means for transmitting a large amount of information such as a guide letter or a pamphlet, a method of enclosing and sealing various advertising materials in an envelope and mailing it is common. However, recently, the management of personal information, etc. has become important, and accidents such as mistakenly describing other people's information in the content or misdelivering due to incorrect addressing must be avoided as much as possible. We also want to reduce the cost of enclosing and sealing a large amount of individual information. Under such circumstances, for example, a folding envelope sheet described in Japanese Patent Application Laid-Open No. 2000-43456 has been proposed.

The foldable envelope sheet described in the above-mentioned cited document is a foldable envelope in which information is described in a one-to-one correspondence on one sheet, so that the information of another person is not mistakenly mixed. In addition, it has the advantage of saving the trouble of enclosing and sealing because it is finished as a sealed letter by folding it. However, the protruding sealing side that requires special processing, the adhesive application for sealing, the cutting sewing machine processing to tear off the sealing piece at the time of opening, the peeling agent application processing to easily peel off the adhesive part, the two-row sewing machine It requires complicated and time-consuming processing such as opening means by eye, and it is expensive despite the above-mentioned advantages.

In view of the above problems, the foldable envelope of the present invention describes information on one sheet to complete a foldable envelope. Since accidents such as misdelivery do not occur and it is deployed in various states after opening, it is easy to check the information and attract the interest of the recipient, and it costs money to minimize the amount of pseudo-adhesive film sheet used. It is intended to provide no folding envelopes.

In order to achieve the above object, the folding envelope of the present invention is a sealed envelope in which a plurality of leaf pieces connected in a horizontal direction via a vertical fold line are connected in two rows in a vertical direction via a horizontal fold line. A foldable envelope in which the sheet is folded from the vertical fold line and then finally folded along the horizontal fold line, and the sheets are peelably bonded between arbitrary facing surfaces via a pseudo-adhesive film sheet. A group of leaf pieces that are sealed by the adhesion of a pseudo-adhesive film sheet that intervenes between the opposing leaf pieces when the edge of the envelope is finally folded along the horizontal fold line, and the left vertical edge is folded inside the folded envelope. The outer two leaf pieces are sealed by the adhesion of a pseudo-adhesive film sheet interposed between the facing surfaces of the edges protruding from the leaf piece group, and the top side is finally along the horizontal fold line with the right vertical edge. When folded, the pseudo-adhesive film sheet that intervenes between the opposing leaf pieces and the pseudo-adhesive film sheet that protrudes from the top of the outer two leaf pieces are sealed by adhesion, and the ground side is formed by folding each leaf piece. It is characterized by being sealed according to the aspect.
are doing.

In the folded envelope of the present invention, the lower edge is finally the folded line portion (folded portion) when the entire sealed sheet is folded in half, so that the folded line portion (folded portion) is closed like a bag. It is in a state of being. Therefore, the remaining three sides are configured to be sealed by a pseudo-adhesive film sheet formed in the minimum area and a folded form in which the width of the leaf piece is taken into consideration.

As the material used for the folding seal of the present invention, for example, ordinary paper such as high-quality paper, matte paper, coated paper, synthetic paper, non-woven fabric, resin film sheet and the like can be preferably used. Then, the pseudo-adhesive film sheet can be suitably used as a pseudo-adhesive means for adhering the folded facing surfaces to each other so as to be peelable and sealing the whole.

The pseudo-adhesive film sheet is compatible with thermal laminating in which a known heat-sensitive adhesive layer is formed on one surface of a base material such as polyethylene terephthalate or biaxially stretched polypropylene, and a pseudo-adhesive layer is formed on the remaining other surface. There is a thing. This product is coated on the surface of the paper to be pseudo-adhesive after printing, folded so that the pseudo-adhesive film sheets face each other, and is peelably bonded by applying pressure or heating / pressurizing treatment.

Further, the folding envelope of the present invention is completed by folding one envelope sheet vertically and horizontally, but the folding means such as perforations and creases formed in the folding line can be used as a material for the folding envelope in advance. It may be formed or may be formed together with a pseudo-adhesive film sheet coated during the manufacturing process. Further, depending on the nature of the material (weight, brand, etc.), it may be forcibly folded with a folding machine without applying anything.

The folding envelope of the present invention is initially folded from the vertical fold line, and then the leaf pieces divided vertically from the horizontal fold line are folded in half to finish, for example, a long 3 size or mail service size envelope. Then, when the leaves are folded from the lateral fold line, the facing surfaces of the opposing leaf pieces are detachably adhered to each other. By doing so, the lower edge is sealed in a folded state in a traditional Chinese bookbinding state, and the upper edge is sealed by bonding the pseudo-adhesive film sheets coated so as to protrude from the upper edge on the planned pseudo-adhesive surface. Further, the left and right edges are sealed with the edges of each leaf piece covered with the pseudo-adhesive film sheet.

The edge that is bound to the bag by folding from the final horizontal fold line is expressed as the lower edge, but the upper edge may be closed in a bag shape by the design of the folded envelope. In the case of designing in the lateral longitudinal direction, one of the left and right edges is a closed side in the shape of a bag.

The folding envelope of the present invention describes all the information on one sheet and finishes it as a folding envelope. And no serious accidents such as information leakage caused by it will occur.
Further, since the forming area of the pseudo-adhesive means is minimized, the cost can be kept low.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The material of the folding envelope used in this embodiment is ordinary matte coated paper (46-equivalent 70 kg).
Further, in the pseudo-adhesive film sheet G used in this embodiment, a known heat-sensitive adhesive layer made of polyethylene is formed on one surface of a base material made of biaxially stretched polypropylene or the like, and a pseudo-adhesive film sheet G made of polyethylene is formed on the other surface. It corresponds to the thermal laminating method in which an adhesive layer is formed, and is used for ordinary print lami.

[Folding Envelope F]
The folded envelope F of the present embodiment shown in FIGS. 1A, 1B and 2 is made from, for example, the envelope sheet S shown in FIGS. 3A and 3B. In the sealed sheet S, the first leaf piece 1, the second leaf piece 2, the third leaf piece 3, and the fourth leaf piece 4 connected in the horizontal direction by the vertical fold lines 9, 10 and 11 are similarly formed in the vertical fold line. The first leaf piece 1 and the fifth leaf piece via the fifth leaf piece 5, the sixth leaf piece 6, the seventh leaf piece 7, the eighth leaf piece 8, and the lateral fold line 12 connected laterally by 9, 10 and 11. 5. The second leaf piece 2 and the sixth leaf piece 6, the third leaf piece 3 and the seventh leaf piece 7, and the fourth leaf piece 4 and the eighth leaf piece 8 are vertically connected so as to be adjacent to each other.

As shown in FIG. 4A, the surface of the sealed sheet S is covered with the pseudo-adhesive film sheet G in a state where substantially the entire surface of the second leaf piece 2 and the sixth leaf piece 6 protrudes from the upper and lower edges. Further, as shown in FIG. 3B, the back surface of the sealed sheet S is covered with the pseudo-adhesive film sheet G in a state where substantially the entire surface of the first leaf piece 1 and the fifth leaf piece 5 protrudes from the upper and lower edges. According to the present invention, by covering the two places with the pseudo-adhesive film sheet G, it is possible to seal the periphery of the folded seal F (four edges on the left and right sides of the top and bottom).

It is also possible to form folding means such as a folding sewing machine or a folding streak on the vertical folding lines 9, 10 and 11 and the horizontal folding line 12 so that the folding lines can be folded accurately. In this embodiment, folding sewing machines are formed on all the folding lines.

As shown in FIGS. 5 (A), 5 (B) and (C), the sealed sheet S having the above-described configuration has the first leaf piece 1 and the second leaf piece 2 having the back surface of the third leaf piece 3 and the fourth leaf piece 3 and the fourth. The back surface of the fifth leaf piece 5 and the sixth leaf piece 6 is folded from the vertical fold line 10 so as to face the back surface of the leaf piece 4, and the back surface of the fifth leaf piece 5 and the sixth leaf piece 6 faces the back surface of the seventh leaf piece 7 and the eighth leaf piece 8.

As shown in FIGS. 6 (A), 6 (B) and 6 (C), the sealed sheet S after the first folding is continuously folded so that the surfaces of the third leaf piece 3 and the fourth leaf piece 4 face each other. Also, the seventh leaf piece 7 and the eighth leaf piece 8 are folded from the vertical fold lines 9 and 11 so as to face each other.

As described above, the sealed sheet S that has been folded second is laterally oriented so that the surfaces of the second leaf piece 2 and the sixth leaf piece 6 (covered with the pseudo-adhesive film sheet G) face each other at the end. It is folded in half from the fold line 12 and folded in the state shown in the cross-sectional view of FIG. 1 (B). At this point, the pseudo-adhesive film sheets G of the second leaf piece 2 and the sixth leaf piece 6 are not adhered to each other, and the protruding pseudo-adhesive film sheets G of the first leaf piece 1 and the fifth leaf piece 5 face each other. The edge portion is also in an unbonded state, but the bonding is completed by applying a pressure or a heat-pressurization treatment.

As shown in FIG. 1 (B), the folded seal F thus formed is formed by bonding a pseudo-adhesive film sheet G having a vertical edge on the right side interposed between the facing surfaces of the second leaf piece 2 and the sixth leaf piece 6. It is sealed, and the left vertical edge is sealed by the adhesion of the pseudo-adhesive film sheet G interposed between the facing surfaces of the edges protruding from the left vertical edge of the other leaf pieces of the first leaf piece 1 and the fifth leaf piece 5. To.

Further, as shown in FIG. 2, the top side of the folded seal F is sealed by the adhesion between the pseudo-adhesive form sheets G protruding from the leaf piece group, and the ground side is closed in a bag shape by folding each leaf piece. In this way, all four laps of the folded seal F are sealed.

The recipient of this folded seal F is, for example, the second leaf piece 2 and the sixth leaf piece 6, or the sixth leaf piece 6 from the non-adhesive area not covered with the pseudo-adhesive film sheet G on the left and right vertical edges shown in FIG. 1 (B). The protruding sealing edges of the one-leaf piece 1 and the fifth leaf piece 5 are peeled off, and then the adhesive between the protruding pseudo-adhesive film sheets G on the top side is peeled off, and finally shown in FIGS. 4 (A) and 4 (B). It can be developed on a flat surface and the internal information can be confirmed as it is or through the transparent pseudo-adhesive film sheet G.

The present invention is not limited to the above examples.
For example, in the above embodiment, the sealed sheet S in which the leaf pieces of four leaf pieces are arranged vertically in two rows is used, but the number of leaf pieces may be a sealed sheet in which more leaf pieces are arranged. The point is that the right vertical edge is sealed by the adhesion of the pseudo-adhesive film sheet G that is interposed between the opposing leaf pieces when finally folded along the horizontal fold line, and the leaf pieces that are folded inside the folded envelope. Any configuration may be used as long as the left vertical edge is sealed by the adhesion of the pseudo-adhesive film sheet G interposed between the facing surfaces of the protruding edges of the two leaf pieces that enclose the group. The seals on the top and bottom are as described above.

In addition, there is no limit to the width of protrusion from the other leaf pieces of the two leaf pieces that are exposed and wrap around the whole, and the wider the protrusion width, the more reliably the left vertical edge is sealed, although it depends on the function of the manufacturing equipment. Can be done.
