Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to envelopes, and more particularly to a sealing means for a one-sided openable envelope in which an opening is provided on one side of the envelope.

BACKGROUND TECHNOLOGY In the case of a conventional one-sided openable envelope, a sealing piece extending from one edge of the opening is bent, and either the sealing piece or the other edge of the opening opposite to the inner surface of the sealing piece is folded. It is sealed by applying an adhesive such as glue, or by gluing a folded sealing piece with an adhesive tape.

Problems that the invention aims to solve: According to the conventional sealing methods mentioned above, to open the seal, you use scissors or a pepper knife, or break the seal by hand, but you don't have scissors or a paper knife at hand. Sometimes it is troublesome to search for the envelope, and it is not easy and clean to tear it apart by hand.In addition, both methods produce chips that are difficult to dispose of, and in some cases, the contents of the envelope are also included. It had many drawbacks, including breakage.

An object of the present invention is to provide an envelope equipped with a sealing means that eliminates such drawbacks.

Means for Solving the Problem A sealing piece is provided on one edge of the envelope opening, extending from the folded part as a boundary, while a sealing piece is provided on the other edge of the opening, separated from the folded part in the opposite direction from the sealing piece. A tear-off piece is provided which is folded back to the outside at a perforation for folding and cutting provided at a position, and at least one of the tear-off piece and the sealing piece is provided with a tear-off piece that is folded back at the folding part for sealing. An adhesive part is provided so that they can be attached to each other.

Function When sealing, the sealing piece is folded at the bending part and attached to the tear-off piece at the sticking part. When opening the seal, when the sealing piece is pulled up, the tear-off piece stuck to the sealing piece at the sticking part is removed. When a force is applied to the folding/cutting perforation located away from the folded portion, the perforation is easily broken and separated from the envelope, and the envelope is opened.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is a plan view of the envelope in an unused state, FIG. 2 is a sectional view of the envelope in a sealed state, FIG. 3 is a plan view of the envelope in an opened state, and FIG.
The figure is a sectional view thereof, and FIGS. 5 and 6 are plan views showing an example of an envelope manufacturing method.

First, the structure of the envelope will be explained along with its manufacturing method based on FIGS. 5 and 6.

First, the structure of envelope paper 1, which becomes an envelope, will be explained based on FIG. 5. Figure 5 shows the inner side of the envelope paper 1 (the side that becomes the inner surface when it is made into an envelope). A sealing piece 6 is arranged in series with the folding perforation 4 as a boundary, and a sealing piece 6 extends through the folding perforation 5, which is a folding portion, at the opposite end of the envelope top sheet 2 from the folding perforation 4. It is set up. A folding/cutting perforation 7 and a plurality of transfer holes 8 equally spaced from each other are provided along the edge of the lower envelope sheet 3 opposite to the folding perforation 4, and the folding/cutting perforation 7 The part on the end side from 7 constitutes a separation piece 9. Further, the sealing piece 6 is provided with a cutting perforation 10 and a plurality of transfer holes 11 spaced at equal intervals along the end opposite to the folding perforation 5, and the above-mentioned on the inner surface The tear-off piece 9 is placed at a position equal to the width of the tear-off piece 9 from the folding perforation 5.
An adhesive portion 12 having a width substantially the same as the width of the adhesive portion 12 is provided. The adhesive part 12 is composed of an adhesive 13 applied to the inner surface of the sealing piece 6 and a release paper 14 releasably adhered to the adhesive 13. Further, on the inner surfaces of each of the upper envelope sheet 2 and the lower envelope sheet 3, along both side edges extending perpendicularly to the folding perforation 4, there are lines symmetrical to the folding perforation 4, which are normally not bonded. , adhesives 15, 16, 1 that can be bonded under specific conditions such as pressure, heat, moisture, etc.
7 and 18 are applied. As is clear from FIG. 5, each of the adhesives 15, 16, 17, 18 is
The tear-off piece 9 portion of the lower envelope sheet 3 and the portion of the upper envelope sheet 2 from the folding perforation 5 that is approximately the same width as the tear-off piece 9 are not provided.

Although not shown, the envelope paper 1 is usually one in which a large number of paper envelopes 1 are arranged in a row in the width direction (in the upper and lower directions in FIG. 5) with cutting perforations as boundaries. When the envelope paper 1 is in such a connected state, the transfer holes 8 and 11 are engaged with tractor pins (not shown) and transferred in a predetermined direction, and the outer surface of the envelope paper 2 is similarly moved. A printer connected to a computer (not shown) prints out the destination and sender's information, and then the message is divided into single pieces. In this case, the separation portion 9 also serves as a marginal portion.

In order to create an envelope using the envelope paper 1 described above, first, the cutting perforation 10 of the sealing piece 6 is broken and the transfer hole 11 portion is cut off. Next, by folding along the folding perforations 4, the inner surfaces of the upper envelope sheet 2 and the lower envelope sheet 3 are overlapped, and adhesive 15 is applied.
and 17 and the adhesives 16 and 18 are brought into contact with each other to provide predetermined bonding conditions and bonded to each other. As a result, as shown in FIG. 6, an envelope 19 with an opening on the side of the sealing piece 6 is created, and the tear-off piece 9 is in a free state with respect to the envelope top paper 2 and can be folded and cut. The edge on the opposite side from the folding perforation 7 is located at a position that substantially corresponds to the folding perforation 5.

Next, how to use the envelope 19 will be explained based on FIGS. 1 to 4.

FIG. 1 shows a state where the tear-off piece 9 of the envelope 19 in the state shown in FIG. 6 is folded back outward at the perforation 7 for folding and cutting. 9 and the adhesive part 1 of the sealing piece 6
2 is located symmetrically with respect to the folding perforation 5. Here, the stored items 20 such as letters are placed in an envelope 19.
When the adhesive 13 is exposed by peeling off the release paper 14 and the sealing piece 6 is folded at the folding perforation 5, the adhesive 13 is positioned corresponding to the tear-off piece 9, and the tear-off piece 9 is The adhesive 13
It is attached to the sealing piece 6 (see FIG. 2) and becomes sealed. At this time, the adhesive 13 also comes into contact with the envelope bottom paper 3 through the transfer hole 8, so that the envelope bottom paper 3 and the sealing piece 6 are also stuck together by the adhesive 13 located in the transfer hole 8 portion. As a result,
The sealing piece 6 and the tearing piece 9 will not be turned over when the envelope 19 is mailed or the like.

When the end of the sealing piece 6 is pulled up from the sealed state shown in FIG. 3 and 4 by separating the envelope from the lower paper 3 in the attached state.
As shown in the figure, the envelope 19 is in an opened state. At this time, the sealing piece 6 is pasted to the envelope bottom paper 3, but this pasting is only done at each transfer hole 8, so it is easy to remove the sealing piece 6 from the envelope bottom paper 3. It can be peeled off quickly and does not interfere with the opening operation.

Note that the present invention is not limited to the embodiments described above, and for example, the transfer hole 8 of the cut-off piece 9 is not necessarily required. Furthermore, the adhesive part 12 is not limited to one in which the adhesive 13 is covered with a release paper 14;
An adhesive that adheres under special conditions such as pressure and moisture may be used, or an adhesive such as glue may be applied at the time of sealing.
may be provided not on the sealing piece 6 but on the surface of the separation piece 9 facing the sealing piece 6. Furthermore, the folded portion of the sealing piece 6 has folding perforations 5.
In addition, the envelope 19 has a folding line 2 that is continuous with the folding perforation 4 as a border.
Of course, it is not limited to the envelope paper 1 having the envelope paper 1 and the envelope bottom paper 3.

Effects As is clear from the above explanation, according to the present invention, the seal is opened by tearing off the tear-off piece attached to the sealing piece at a perforation provided at a position away from the folded part of the sealing piece. The package can be opened easily and cleanly without the use of tools such as scissors, and there are many advantages such as no chips are generated and the stored items are not damaged when the package is opened.
