Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet forming an envelope.

[0002]

2. Description of the Related Art Conventionally, a sender of a letter often puts an envelope for reply in an envelope of outgoing credit when he / she wants a reply to the envelope.

[0003]

However, in order to fit this reply envelope into the outgoing credit envelope, the reply envelope must be folded smaller than the outgoing credit envelope, and must also be put together with the necessary contents into the outgoing credit envelope. Since this is not the case, it is troublesome and time-consuming and complicated, and there is a problem in that the whole is bulky and the mailing fee is high.

Therefore, the present invention is intended to enable the recipient to use the envelope received by the recipient as a reply envelope without having to prepare a separate return envelope.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a margin for gluing on the upper and lower edges and the outer side edges of a pair of left and right rectangular sheets that are connected to each other via a fold line. One side of the rectangular sheet is attached, and an adhesive portion is provided on the front surface of the adhesive sheet provided on one rectangular sheet and the back surface of the adhesive sheet provided on the other rectangular sheet. A break line for cutting the adhesive margin piece was provided in and to form an envelope sheet.

Further, the adhesive portion of the adhesive margin piece is constituted by an adhesive surface provided on the adhesive margin piece and a release sheet covering the adhesive surface from above, or becomes adhesive when it contains water. You may make it comprised by the solid paste which carries.

Further, a thread for cutting the adhesive margin piece may be attached along the breaking line.

With the above-mentioned structure, the destinations of outgoing credits are written on the front surface of the rectangular sheet, the destinations for reply are written on the back surface, and the front surface of these rectangular sheets is the front side. As shown in the figure, while folding in half along the crease line, the adhesive margin piece with the adhesive portion on the front surface is folded into the back surface side, and the adhesive margin piece with the adhesive portion on the back surface is folded in two to form a rectangular sheet. By adhering to the outer periphery via the adhesive portion, a publicly known envelope can be formed.

After the recipient receives the reciprocating envelope thus formed, the recipient envelope is cut along the breaking line provided on the envelope, and the glue strip attached to the outer periphery of the rectangular sheet is cut. When separated, the open credit envelope is opened.

Then, the back side of the rectangular sheet in which the reply address and the like is written is the front side, and the rectangular sheet is folded in two along the crease line, and the adhesive margin piece provided with the adhesive portion on the front surface is used.
When affixed to the outer circumference of a rectangular sheet folded in two via an adhesive portion, a return envelope is formed.

Further, on the adhesive surface of the adhesive portion provided on the adhesive margin piece,
When the release sheet is covered, the adhesive strip can be attached simply by peeling off the release sheet. Alternatively, when a solid paste that is tacky when it contains water is applied, the adhesive paste can be attached simply by wetting the solid paste.

Further, when a thread for cutting the adhesive margin piece is attached along the breaking line, the envelope can be opened by pulling the thread.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings.

The envelope sheets shown in FIGS. 1 and 2 are a pair of left and right rectangular sheets 1 and 2, which are connected to each other via a fold line 3 and have upper and lower sides of the left and right sheets 1 and 2, respectively. The glue margin pieces 4a and 4 which are continuously provided on the edge and the outer side edge.
b, 4c, 5a, 5b, 5c.

The left sheet 1 has a reply address entry field printed on the back surface thereof, and the right sheet 2 has an outgoing credit address entry field printed on the front surface thereof.

A strip-shaped adhesive surface 6 is provided on the front surface of the adhesive margin pieces 4a, 4b, 4c of the left sheet 1 and the back surface of the adhesive margin pieces 5a, 5b, 5c of the right sheet 2, respectively. A release sheet 7 is provided on the surface.

A breaking line 8 for cutting the glue margin pieces 5a, 5b, 5c is provided on the upper and lower edges and the outer side edge of the right sheet 2. Further, on the back surface of the right sheet 2, a thread 9 is provided along the breaking line 8 and the end portion 9 thereof is provided.
The a and 9b extend outward from the rectangular sheet from the upper end and the lower end of the fold line 3, respectively.

The envelope sheet configured as described above is
Used in the procedure described below.

First, as shown in FIG. 3, all the glue margin pieces 4a, 4b, 4c of the left sheet 1 are bent to the back surface side of the left sheet 1, and the back surface of the left sheet 1 and the back surface of the right sheet 2 are folded. Fold it along the line of sight 3. Next, as shown in FIG.
The side edge paste margin piece 5b and the lower edge glue margin piece 5c of the right sheet 2 are peeled off the release sheet 7 from the respective adhesive surfaces 6 and attached to the surface of the left sheet 1.

As a result, the envelope sheet becomes a bag body having an open upper portion, and contents such as letters can be accommodated through this opening, so that a forward envelope is formed. Further, when the upper edge paste margin piece 5a of the right sheet 2 is attached to the upper edge portion of the left sheet 1, this outgoing envelope is sealed as shown in FIG.

After the recipient receives the outgoing credit envelope, he pulls the ends 9a, 9b of the thread 9 extending outward along the rupture line 8 provided on the outer circumference of the envelope, The respective glue margin pieces 5a, 5b, 5c of the right sheet 2 are separated.
Then, the outgoing credit envelope is opened and the contents can be taken out.

As shown in FIG. 6, the recipient opens the folded glue margin pieces 4a, 4b, 4c and folds the surface of the right sheet 2 and the surface of the left sheet 1 on top of each other. And FIG.
As shown in FIG. 5, when the opened side edge paste margin piece 4b and the lower edge glue margin piece 4c are attached to the back surface of the right sheet 2 and after the contents are put in, the upper edge glue margin piece 4a is attached. Similarly to the outgoing credit envelope, a reply envelope as shown in FIG. 8 is completed. At this time, since the reply destination is described in advance in the reply envelope, the recipient may just post it in the post as it is.

In this embodiment, the strip-shaped adhesive surface 6 is used.
Although the release sheet 7 and the release sheet 7 are used, a solid paste which is tacky when it contains water may be used. In this case, when the solid paste is lightly wetted, its surface becomes tacky, and therefore the release sheet 7 is not required.

Further, as a means for opening the outgoing credit envelope,
The thread 9 was provided along the break line 8, but a pair of break lines parallel to each other were formed along the peripheral edge of the right sheet 2, and the portion between the break lines was peeled off from the right sheet 1. Good.

[0025]

As described above, in the envelope sheet according to the present invention, since the envelope used for outgoing credit can be used as it is for replying, the sender has to purposely prepare another envelope for replying. There is no extra effort and time.

Further, when this envelope sheet is used, only the necessary contents are contained in the outgoing credit envelope, so that the whole is not bulky or heavy, and the mailing cost can be saved.
