Abstract

PROBLEM TO BE SOLVED: To form continuous envelopes which can receive even thick contents by pasting pasted bags formed with V-shaped folds which are folded inside of both right and left ends on a continuous sheet. SOLUTION: Three sides of a plurality of pasted bags 4 are sealed along a lengthwise direction of a continuous sheet 1 with numerous feed holes 2 provided along both length wise ends with equal intervals, and the sheet is cut off along perforations 3, 13 to form continuous envelopes 12. At this time, a V-shaped fold 9 folded inward is formed at both side rims of the pasted bag 4, and an outer rim of the fold 9 and a lower end of the bag 4 are folded to provide pasting margins for pasting on a rear face of the continuous sheet 1. Further, two vertically parallel bottom folds 14a, 14b are provided on the continuous sheet 1 and the pasted bag 4 at the lower end of the bag 4. Thus at the time of using the envelope 12, an opening width can be enlarged by the V-shaped fold 9 formed at both sides, while by making the continuous sheet or the bag 4 protrude inward in a V-shape from the lower bottom fold 14b, a bottom can be rectangular.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous envelope in which a large number of laminating bags are attached to continuous paper.

[0002]

2. Description of the Related Art Conventionally, continuous envelopes of this type have been disclosed in, for example, Japanese Utility Model Publication No. 62-110147 and Japanese Utility Model Publication No. 40-3.
In Japanese Patent No. 4316, two continuous papers are bonded to each other to form a bonding bag in which the three sides are sealed, and a large number of feed holes are formed in the longitudinal direction on both sides of the continuous paper to separate the feed hole portions. There is proposed a continuous envelope in which a slit or a perforation is provided between adjacent envelopes to form each of the perforations. This type of continuous envelope is one that feeds various information such as an address and an address by feeding feed holes provided on both sides of the continuous paper to a printing device by a feed mechanism such as a tractor, and puts a photograph. It is widely used in medicine bags, envelopes for direct mail, etc.

[0003]

The conventional continuous envelope described above is merely a continuous forming of a laminated bag for an envelope in which two continuous sheets are stuck together and sealed on three sides, and the separated envelope is simply Since it is a flat sheet made by pasting two continuous paper sheets together, only thin items such as postal items can be placed inside the envelope, and thick contents or large amounts of postal items cannot be put in. However, there is a problem in that the glued portion of the envelope is easily peeled off when trying to forcefully insert such a thick content into the envelope.

The present invention is intended to solve such a problem, and an object thereof is to provide a continuous envelope capable of accommodating a large amount of contents in the envelope.

[0005]

DISCLOSURE OF THE INVENTION The present invention is directed to a continuous paper provided with a large number of feed holes at equal intervals in the longitudinal direction on both sides, and a plurality of laminating sheets which are sealed on three sides in the longitudinal direction of the continuous paper. A continuous envelope having a laminated bag and perforations for separating the laminated bag formed on the continuous paper, wherein V-shaped folded portions folded inward are formed on both left and right edges of the laminated bag. Then, the outer edge of the folded portion and the lower edge of the bonding bag are folded back to form a margin of adhesive, and the margin of adhesive is bonded to one surface of the continuous paper to continuously bond the bonding bag. Therefore, if the laminating bag attached to the continuous paper is separated from the perforations, an envelope in which the laminating bag and the continuous paper are laminated is formed, and this envelope is folded inward on both left and right edges. Since the V-shaped folded portion is formed, the opening width of the envelope is wide and thick. It can be accommodated in volume products.

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 8 show an embodiment of the present invention, in which 1 is a continuous paper on which a plurality of feed holes 2 are formed at equal intervals along the longitudinal direction on both sides. Perforations 3 are formed in parallel with the edges to separate the portion of the feed hole 2 as a thin strip.

As shown in FIG. 1 (a), the laminating bag 4 to be attached to the back side of the continuous paper 1 has notches 5 on both lower end edges.
Is formed to form a trapezoidal flap 7 having both sides 6 on both sides. The flap 7 serves as a margin for the bottom portion of the envelope when gluing. Then, as shown in FIG. 1B, three fold lines 8a, 8b, 8c are engraved on the left and right edges of the bonding bag 4 by a creasing device (not shown). These fold lines 8a, 8b, 8c are habits of a folding part which will be described later, and the innermost fold line 8a is formed from the corner of the cutout 5 to the upper edge of the bonding bag 4, Fold lines 8b and 8c are sequentially formed in parallel on the outer side of the fold line 8a. When the crease lines 8a, 8b, 8c are engraved, the crease line 8d, which becomes the crease of the flap 7, is also formed on the lower side of the laminating bag 4 so as to connect the base corners of the notches 5 at the same time. Engrave.

Then, as shown in FIG. 1 (c), a folding device (not shown) temporarily folds both side edges of the bonding bag 4 inward from the inner fold line 8a, and then the central fold line 8b. It is then folded back to form a V-shaped folded portion 9. (See FIG. 1 (d)) At this time, the portion outside the outermost fold line 8c overhangs the edge of the bonding bag 4, and the portion overhanging from the bonding bag 4 is re-bonded through the fold line 8c. Fold back inside the pouch 4. The portion folded back inward from the fold line 8c serves as a margin 10 for the bonding bag 4. And
By folding back the folding lines 8b and 8c on the outside from the folding line 8a on the inner side, the left and right sides of the bonding bag 4 are folded into a substantially M shape, and finally, as shown in FIG. The outer edge of is folded to fold the folding portion 9 into a flat shape.

After folding the folding portion 9 in this manner,
In order to attach the glue margin 10 of the folding portion 9 and the flap 7 to each other, as shown in FIG. 2A, after the lower end portion of the glue margin 10 is glued, the flap 7 is folded back from the fold line 8d. And glue 10 together. And FIG. 2 (b)
As shown in, the flap 7 and the glue allowance 10 are glued, and the glued portion 11 is pressed against the back surface side of the continuous paper 1 to bond the three-side sealed bonding bag 4 to the continuous paper 1. . In addition, in this embodiment, as shown in FIGS. 3 to 6, the bonding bags 4 are arranged in two rows in the lateral direction and are continuously bonded to the continuous paper 1. In addition, the continuous paper 1 is provided with perforations 13 along the outer contour of the laminating bag 4 for separating the envelope 12. In addition, the outer edges of the bonding bags 4 arranged in two rows are bonded along the perforations 3 which are vertically provided on both side edges of the continuous paper 1 in order to separate the feeding hole 2 portion. The perforation 3 for separating the hole 2 portion also has a function for separating the bonding bag 4.

By pressing the creasing blade (not shown) of the creasing device on the continuous paper 1 in a state where the bonding bag 4 is bonded to the continuous paper 1 so as to correspond to the lower end side of the bonding bag 4. Two bottom folding lines parallel to each other on the lower end side of the bonding bag 4
14a and 14b are engraved on the continuous paper 1 and the bonding bag 4. In each of these bottom folding lines 14a, 14b, the distance from the lower edge of the bonding bag 4 to the bottom folding line 14a on the upper side is the maximum opening width of the bonding bag 4, that is, the folding lines 8a, 8c of the folding part 9. The fold lines 14b on the lower side are set to be substantially equal to the interval, and the fold lines 14b on the lower side are carved in the middle portion between the bottom fold line 14a on the upper side and the lower edge of the bonding bag 4.

According to the present invention constructed as described above, a tractor (not shown) is hooked on the feed holes 3 formed on both side edges of the continuous paper 1, and the tractor is rotated to continuously connect to a printer (not shown). Then, various information such as customer name and date is printed. In this printing, the laminating bag 4 attached to the continuous paper 1 is fed with the flap 7 serving as the bottom toward the front side in the feeding direction (direction of arrow A in the figure). In this case, when the bonding bag 4 is stuck to the continuous paper 1, the V-shaped folding portions 9 are formed on both sides of the bonding bag 4, but the bottom side of the preceding bonding bag 4 is a flap. Since 7 is simply pasted onto the continuous paper 1 (see FIG. 7), the bottom side of the pasting bag 4 is extremely thin, and when sent out to a printing device (not shown), the bottom of the pasting bag 4 is caught and printing is disturbed. It can be smoothly supplied to the printing device without any fear of causing a trouble. After printing in this manner, the laminating bag 4 is separated from the perforations 3, 13 formed on the continuous paper 1 as shown in FIG. 4, thereby forming the envelope 12 bonded with the continuous paper 1. However, in the state where the envelope 12 is separated from the continuous paper 1 as described above, as shown in FIG. 7, the upper side of the envelope 12 spreads in the width direction by the folding portions 9 on both the left and right edges, but the lower end portion. It becomes V-shaped narrower toward the side. However, since two parallel bottom folding lines 14a and 14b are formed on the front and back sides of the envelope 12 on the lower end side, the continuous paper 1 or the bonding bag 4 (from the bottom folding line 14b on the lower side is formed as shown in FIG. (In FIG. 8, the bonding bag 4 side is shown)
The region from the bottom fold line 14a on the upper side to the lower end edge of the bonding bag 4 is folded at a substantially right angle by bending it so as to bite it inwardly in a V shape, whereby the envelope
The bottom of 12 is the corner bottom. Therefore, the V-shaped folding portions 9 formed on both sides of the envelope 12 (bonding bag 4) allow the envelope to be enveloped.
Since the opening width of 12 can be widened and the bottom of the envelope 12 has a square bottom, it is possible to store thick contents inside the envelope 12, and also to store such thick contents in an envelope. Even if it is put in 12, there is no concern that the glued part 11 will peel off.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments.
Various modifications can be made within the scope of the present invention.
For example, in the above-described embodiment, an example in which the left and right two rows of the bonding bags are continuously bonded to the continuous paper is shown, but one or more rows of the bonding bags may be continuously bonded.

Further, the laminated bag is not limited to being formed from a sheet, but may be formed by forming a V-shaped folding portion and a glue margin on a continuous paper supplied from a winding paper and then separating the same.
