Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an envelope for the purpose of easily and surely opening the envelope without using an opening device after closing the envelope and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, to open envelopes, usually, using scissors, an opening device, or other device,
Or sometimes it was broken by hand.

Further, there has been known a device in which a peeling band with a cutoff line is provided in a part of an envelope (Japanese Utility Model Publication No. 57-10979), or an envelope in which a yarn for opening is provided in a fold of a lid piece of the envelope.

[0004]

Problems to be solved by the invention:
There was a problem that it was difficult to open the container neatly without using the device.

In addition, the invention of incorporating the yarn for opening in the fold of the lid piece of the envelope not only causes processing restrictions during bag making, but also requires a special process and material in that something other than paper is used. There was a problem.

Next, in the invention of providing a peeling strip with a cutting line, there is a problem that it is necessary to consider that the sewing machine wire portion of the sealing piece is not adhered and the starting point of the peeling strip should be clear and easy to cut. .

The sewing wire in the above-mentioned prior art is usually provided after bag making. However, since the envelope is individually performed by the user of the envelope, the sewing machine wire of the envelope and the sewing wire of the envelope are not always designed as intended by the inventor.
This is because the sewing lines of the sealing pieces are not sealed so that they overlap exactly. Further, the one in which the cutting perforation wire is provided in a place other than the lid piece not only requires a separate process after bag making, but also has a problem that psychological resistance is caused by opening a place other than the opening side. It was

[0008]

According to the present invention, a sewing machine wire for cutting a sealing lid piece and a cutting machine wire for cutting provided on the front and back sides of an envelope are designed to be precisely overlapped and sealed. The above-mentioned conventional problems have been solved. In the Western envelope, the short-side sealing piece can be opened by treating the short-side sealing piece in the same manner as the lid piece.

For example, when the peeling piece is used, there is a risk that the peeling piece may be cut, but according to the present invention, there is no possibility of the above, and it is possible to surely open without using a device for opening.

That is, the invention of the method is characterized in that a folding means is provided at the base of the lid piece portion of the sheet, and the folding means is sandwiched, and the perforating sewing lines are provided at equal intervals and in parallel, and then the bag is made. Is a method of manufacturing envelopes. Still another aspect of the present invention is to provide a folding sewing line of a lid piece on one side of a sheet, and symmetrically provide cutting perforation lines on both sides of the folding sewing line, and then punch the envelope into a developed form. Then, the method for producing envelopes is characterized by making a bag. Next, another invention is to provide a folding perforation line of the seal on one side of one short side of the Western-style envelope paper, and to provide perforating perforation lines symmetrically and in parallel on both sides of the perforation perforation line. After that, it is a method for manufacturing envelopes, which is characterized by punching into an expanded form of an envelope, and then making a bag. Another aspect of the invention is to form an envelope in the usual manner using envelope paper, provide a folding sewing line at the base of a lid piece of the envelope, and sandwich the folding sewing line. This is a method of manufacturing envelopes, which is characterized by symmetrically providing perforation lines for cutting.

Further, the invention of the product is such that, when the envelope is sealed to the opening side, a sewing machine wire for opening is provided at the same position of the lid piece and the front and back paper of the mouth, and a sewing machine for folding is provided at the base of the lid piece. An envelope characterized by having a line. The above-mentioned envelopes refer to long envelopes, rectangular envelopes, Western envelopes, and other paper bags in which lid pieces are stuck and sealed.

Next, as a means for preventing the movement of the contents document, a small piece of paper is folded or attached by dots so that the edge of the document does not move to the cutting sewing machine side.

[0013]

According to the present invention, the sewing machine wire for opening provided on the lid piece or the sealing piece and the sewing machine wire for opening provided on the front and back papers of the envelope are vertically aligned and overlap with each other. By cutting along the line, it can be opened accurately and neatly.

Since the opening is exclusively performed by cutting with the sewing machine wire, it is of course not necessary to use an opening tool, and the cutting can be surely performed. Further, since the user folds the lid piece along the fold perforation line, the opening perforation line is automatically overlapped and there is no risk of misalignment. Since the Western-style envelope is sealed at the time of bag making, the sewing machine wire for opening can be accurately overlapped.

[0015]

Example 1 The front and back papers 2 and 2a of the envelope, the lid piece 3 and the envelope piece 4 are printed on the band-shaped paper 1, and then the perforation line 5 is formed at a position corresponding to the fold of the lid piece 3. Set up. This sewing line 5
Is a fold easily, but a relatively small hole (for example, a hole and a connecting portion is 1: 1) of the sewing machine that is not easily cut. Next, perforation lines 6 and 7 for cutting are provided symmetrically and in parallel with the perforation line 5 as a center. The perforating machine lines 6 and 7 (for example, 2: 1 or 3: 1 to make the holes larger) are provided with relatively large perforations in a straight line so that they can be easily cut off by applying a force.
Next, the envelope paper 8 is punched from the band-shaped paper 1, glue is applied to the glue margin portions 9 and 10 (the back side in FIG. 2), and the edge 11 and the envelope 4 are sequentially stacked to form a bag. This bag making method is the same as a conventionally known method. However, each sewing wire can also be provided in the punching molding process (FIGS. 1 and 2).

The envelope 12 made as described above is
When the lid piece 3 is bent and attached at the time of use, the sewing machine lines 6 and 7 are overlapped with each other as shown in FIG.

In the above embodiment, the sewing machine wire for opening is provided on the opening side of the envelope 12, but it can be provided on the bottom side of the envelope by the same method.

[0018]

[Embodiment 2] The sewing line 6 of the lid piece 3 is attached to the sealing side of the envelope 12.
And the perforation line 7 on the front and back sheets of the envelope 12 are provided so as to overlap with each other. At the base of the lid piece 3, a perforation line 5 is provided in parallel with the perforation line 6 so that the lid piece 3 can be folded at the correct position. Reference numeral 13 in FIG. 3 is a perforated sewing wire provided on the bottom side of the envelope.

All the means for accurately bending the lid piece 3, such as a kerf or an embossing wire, in place of the sewing line 5 for folding, belong to the scope of the present invention.

[0020]

[Third Embodiment] A perforation line 16 for folding the envelope 15 is provided on one side of the short-side forming paper of the Western envelope paper 14. The sewing line 16 is a fold easily, but it has a relatively small hole (for example, the size of the hole and the connecting portion is 1: 1) of the sewing machine that is not easily cut. Next, perforation lines 17 and 18 for cutting are provided symmetrically and in parallel with the perforation line 16 as a center. The cutting perforation lines 17 and 18 (for example, the ratio of the hole portion to the connecting portion is set to 2: 1 or 3: 1 to make the hole portion large) can be easily cut by applying an external force. A relatively large sewing hole is provided in a straight line.
Then, the glue margin portions 19 and 20 of the envelope sheet 14 (the back side in FIG. 5)
A glue is attached to the bag, and the sealing piece 15 and the end edge 21 are sequentially stacked to form a bag, thereby forming a Western envelope 22 (FIGS. 5 and 6). In the figure, 15a is a sealing piece on the other side, 23 is a lid piece, and 24 is a fold line for folding the lid piece 23.

In the above-described embodiment, the perforation lines 17, 1 for cutting are used.
Although 8 is provided only on the sealing piece 15 side, it may be provided on the sealing piece 15a side or both sealing pieces 15 and 15a.

In the above embodiment, the small hole 2 is formed in the sealing piece 15.
5 and 25 are provided (close to the perforation line for cutting), the end edges 21 are overlapped, and glue is applied to the glue margin portion 19 thereof so that a part of the glue in that portion passes through the small hole 25. Since it adheres to the inner wall on the cover side (shown by a chain line in FIG. 5), the document does not move beyond the cutting machine line for cutting to the edge when the document is put in the envelope.

A protrusion (emboss) is used instead of the small hole 25.
Alternatively, it may be a folded piece. In essence, a blocking means is provided so that the document does not move beyond the perforation line for cutting.

Next, the embodiment of FIG. 7 shows a case where the present invention is applied to a rectangular envelope, in which 26 is an envelope and 27 is a perforating machine wire, and the bag making method is the same as in the first embodiment.

[0025]

Fourth Embodiment Envelope 29 is formed using envelope paper 28,
A perforated sewing wire 31 is provided on the base of the lid piece 30 of the envelope 29.
Are drilled so that the ratio of the hole portion 31a to the connecting portion 31b is around 1: 1. Further, cutting machine lines 32, 33 for cutting are provided in a straight line symmetrical manner with the machine line 31 for folding being sandwiched therebetween.
The sewing machine wires 32 and 33 define the ratio of the hole portions 32a and 33a to the connecting portions 32b and 33b to about 2: 1 to 3: 1.

When the lid piece 30 is bent from the fold perforation line 31, the perforation perforation lines 32 and 33 are accurately overlapped, so that the perforation line can be easily cut and opened at the time of opening.

The glue allowance in each of the above embodiments is not necessarily constant because it may be provided on one or the other of the sticking portions. Therefore, it is provided on the side convenient for bag making.

[0028]

According to the present invention, since the lid piece (or the sealing piece) is provided with the folding means so that the lid piece can be bent accurately, the user of the envelope can seal the lid piece with normal caution. For example, the cutting perforation lines correctly overlap each other, and there is an effect that the perforation perforation lines can be cut off and opened without using an opening device.

Further, by providing the perforation sewing line, there is an effect that the folding can be performed accurately along the fold.
