DESCRIPTION OF THE PREFERRED EMBODIMENTS Some embodiments of the present invention will be described below with reference to the drawings. (1) Description of First Embodiment A first embodiment of the present invention shown in FIG. 1A shows a vertically long bag that can be used as a mail envelope or a storage bag used for storing documents. . As shown in the figure, this bag is provided with a bag main body 1 into which documents and the like are to be inserted, and a flap 2 integrally formed so as to protrude further upward from the front portion of the bag. For example, chemical pulp, Yupo special paper, Oper , Kraft paper, recycled paper, etc. Appropriate pictures, characters, colors and the like are printed on the outer surface side of the flap 2 to form an apparent sticker portion 3, and a sticking portion 2 a to be attached to the bag body 1 on the back surface side of the flap 2.
Are formed. Further, the flap 2 is formed with a separation portion 2b that can be separated from the attachment portion 2a.
The flap 2 is bent toward the back side of the bag and is adhered to the back side of the bag to seal the opening 2e of the bag.

Here, FIG. 1 (a) shows the front side of the bag, and a thick solid line 2c crossing substantially the center of the flap 2 indicates that a cut has been made. A part of the cut 2 c is formed on the flap 2 along the outline of a part of the sticker part 3 to the cut part 2 b side.

Further, the bag of this embodiment is provided with an opening confirmation section 2d. The unsealing confirmation portion 2d is formed by a dotted-line cut formed by penetrating along the other outline of the sticker portion 3 to the sticking portion 2a side. if,
If an unrelated third party tries to open the bag without permission, the broken line of the opening confirmation section 2d is broken, which is effective in preventing unauthorized opening.

FIG. 1B shows the back side of the bag. As shown in this figure, a release paper 5 that covers the adhesive applied to the flap 2 is attached to an attaching portion 2a that is attached to the bag body 1 on the back side of the flap 2. The release paper 5 is formed of a known paper or a thin synthetic resin film or sheet, and a silicone resin is applied to the surface of the sheet in contact with the adhesive in order to protect the adhesive surface of the adhesive and to provide releasability. ing. Note that the adhesive is applied to the attaching portion 2a of the flap 2.
, As well as at least a portion of the sticker portion 3 protruding to the cut-off portion 2b side, and the release paper 5 is formed in a shape that completely covers at least the adhesive surface. .

Here, as shown in FIG. 2A, the cut 2c between the sticking portion 2a and the cut-off portion 2b is formed by the adhesive layer 6
As shown in FIG. 2B, when the release paper 5 is removed, the cutout 2b and a part of the adhesive layer 6 are separated from the cutout 2c by the bag body 1 as shown in FIG. And is separated from the sticking portion 2a of the flap 2 which is formed integrally with the flap 2. The depth of the notch 2c only needs to reach at least the flap 2 and does not have to reach the adhesive layer 6, but it is necessary that the notch 2c be formed so as not to reach the release paper 5. Although not shown in FIGS. 2A and 2B, the dotted cut 2d is also formed by the cut 2c.
It is cut until it reaches the adhesive layer 6 in the same manner as described above.

When the opening 2e of the bag is sealed with the flap 2, as described above, when the release paper 5 attached to the back surface of the flap 2 is picked and peeled off with the fingers, the affixing portion 2a and the separating portion 2a are separated. 2b along the cut 2c between
Are separated as shown in FIG. At that time, in the sticker portion 3, the cut-off portion 2b is separated along the cut 2c provided along the contour of the protruding portion. Accordingly, as shown in FIG. 3A, the separation portion 2a of the flap 2 can be separated only by the operation of peeling the release paper 5. Thus, with the adhesive layer 6 of the sticking portion 2a of the flap 2 exposed, the flap 2 is folded toward the back side of the bag body 1 to seal the opening of the bag body 1 as shown in FIG. be able to.

Here, when the sealed bag is opened, the flap 2 is peeled off from the bag body 1 as shown in FIG.
Due to the dotted cut 2d formed along the outline of the sticker portion 3 of the flap 2, the sticker portion 3 is peeled off at a portion other than the sticker portion 3 in the sticking portion 2a while being stuck to the bag body 1 and opened. Will be done.

Next, an example of a method for manufacturing a bag with a flap according to the first embodiment of the present invention will be described. In the following description, an example will be described in the case of forming a mail envelope.
As shown in FIG. 5, the paper 10 which is the material of the envelope wound around the roll 6a is pulled out, and the printing machine 6b uses the printing machine 6b to design the address, name, sticker part 3, etc. of the sender by offset printing, letterpress printing, etc. At a predetermined position on the paper 10. FIG. 5 shows a plate cylinder 6b which is a part of the printing machine 6b.
1 and the impression cylinder 6b2 are shown.

Next, in the first cutting section 6c, a cut is made in the paper 10 along the contour of a portion unnecessary for forming an envelope. This cutting is performed, for example, using the roller unit 15 shown in FIG. The roller unit 15 is composed of a roller 15b provided with a cutter C having an outline of an unnecessary part and a roller 15a for pressing the wound paper 10 against the roller 15b. A cut is made around an unnecessary portion (shaded portion in FIG. 7) shown in FIG.

Next, at the crimping portion 6d, a fold when the envelope is folded into a bag shape (the dashed line 1a shown in FIG. 8A).
On paper 10. The fold 1a is formed, for example, by pressing the two rollers when the paper 10 passes between the pair of rollers 20 and 21 shown in FIG. 8B. When the paper 10 is inserted into the rollers 20 and 21, the paper 10 is inserted so that the surface serving as the surface of the envelope contacts the roller 21. One portion 20 of the pair of rollers has a portion corresponding to the muscle pressing portion 6d (the left end in the drawing) protruding in an annular shape, and the annular protruding portion 20a is fitted into a concave portion 21b formed at an end portion of the roller 21 opposed thereto. The fold 1a is formed on the paper. After the creasing step, in the gluing section 6e, the glue contained in the glue tank 17 is adhered to the roller surface in contact with the paper 10 by the roller bearing 16 as shown in FIG. Then, when the paper 10 flowing downstream contacts the roller, the glue attached to the surface thereof is applied to, for example, a glue margin 1b indicated by oblique lines in FIG. 8A.

After the gluing, a cut is made in the paper 10 at the second cutting section 6f so as to cut the envelope 10 thereafter. Next, in the folded portion 6g, as shown in FIG. 10, each side surface of the envelope is folded at the fold 1a, and the side surfaces glued by the upstream gluing portion 6e are bonded to form a bag shape with both ends open. . Next, in the flap processing section 6h, the roller bearings 16 are fixed in the same manner as the gluing in the gluing section 6e.
Then, a release tape 5 is adhered on the paste.

Then, cuts 2c and 2d are formed in the flap 2 by the flap cut processing section 6i. These cuts 2c, 2d are, for example, etched in the form of cuts 2c (see FIG. 1 (a)) of one of the rollers 22 when passing between the two rollers 22, 23 as shown in FIG. Blade (or pinnacle blade, engraving blade) 2
4 by pressing the flap 2. The cut 2d for opening confirmation can be formed by the same method as the cut 2c. In this case, the roller 22 is cut along with the etching blade 24 along the dotted line 2d (FIG. 1).
(See (a)), if an etching blade (for example, a sewing machine blade) intermittently protruding is provided,
The cuts 2c and 2d can be formed at one time. The cuts 2c and 2d may be formed in separate steps.

Thereafter, in the bottom lid gluing section 6j, the lid at the bottom of the envelope body 1 is also glued. The bottom cover is glued by the roller bearing 16 in the same manner as the gluing in the gluing section 6e, and is bonded to the envelope main body 1, whereby the envelope shown in FIG. 1A is completed.

As described above, according to the method for manufacturing an envelope according to the first embodiment of the present invention, it is only necessary to insert a step of forming a cut into a flap into a known envelope manufacturing process.
It is relatively simple because only one process is required as compared with the production of a normal envelope. According to the envelope of the present invention manufactured in this way, since the sticker portion 3 is printed on the sticking portion 2a in advance, the sticker portion itself does not peel off or cut due to contact with another envelope, Does not reduce the decorative effect of the envelope.

Further, when the release paper 5 is peeled off, the separation portion 2b
Is separated from the affixing portion 2b together with the release paper 5, and a part of the sticker portion 3 is in a protruding state. Therefore, no special operation for peeling off the sticker portion 3 is required, and the sealing is performed without applying glue. Since it can be performed, complicated work can be omitted.

If the sticker portion 3 is opened after being sealed, the sticker portion 3 may remain attached to the envelope body 1 without peeling off, so that the decorative effect of the sticker portion 3 can be ensured even after opening. On the other hand, once the sealed envelope is opened, the connected portion (the portion between the cuts) of the dotted line cut 2d for confirming the opening formed around the sticker portion 3 is also cut. Therefore, for example, if this connection is broken before the recipient opens, even if somebody glues and seals again after opening, it will be visible that the connection has already been opened. A person who can easily perform management and notices a dotted line cut 2d formed around the sticker portion 3 may give up opening, so that unauthorized opening can be prevented.

In the production of the envelope, the cuts 2e and 2d are made after the flap 2 is glued, and conversely, the gap between the sticking portion 2a and the separating portion 2b is first cut, and then the glue is cut. Compared to the operation of attaching the release paper 5,
The flap 2 can be easily manufactured.

(2) Description of a First Modification of the First Embodiment The envelope according to a first modification of the first embodiment shown in FIG. This is different from the envelope of the first embodiment in that glue is applied.

Therefore, the envelope according to the first modified example does not require the use of the release paper 5 unlike the envelope according to the first embodiment. Since the release paper is not used in this manner, as shown in FIG. 12A, the cuts to be made in the flap 2 are replaced by dotted line perforated lines 2e instead of the cut lines 2c as in the first embodiment. As shown in FIG. 12B, the sticking portion 2a and the separating portion 2b are separated from each other at the perforation line 2e.

After separating the cut-off portion 2b along the dotted line 2e, the water glue applied to the sticking portion 2a is wetted with water, and the flap 2 is folded into the envelope main body 1, whereby the envelope is folded. Seal.

The production of this envelope is similar to that of the first embodiment except that the step of attaching the release paper 5 in the flap processing section 6h is unnecessary.
Although it can be manufactured in the same manner as the envelope according to the embodiment, in the flap cut processing section 6i, the roller 22 is formed around the sticker section 3 together with the etching blade in the shape of the dotted line 2e. An etching blade corresponding to the perforation confirmation sewing line 2d is provided. Thereby, the paper 10 is pressed between the roller 22 and the roller 23, so that the perforations 2 e and 2 d are formed in the flap 2. Further, if a drying step of drying the moisture of the water paste by applying ultrasonic waves or hot air after applying the water paste used for sealing by the roller bearing 16 is added, the envelope can be manufactured quickly.

According to the envelope according to the first modification of the first embodiment, the sticker portion 3 is printed on the sticking portion 2a in advance, similarly to the envelope according to the first embodiment. In addition, the sticker portion 3 itself is not peeled off or cut off by being overlapped with another envelope or the like, and in use, the cut-off portion 2b is separated from the sticking portion 2a, and a part of the sticker portion 3 protrudes. The state is rich and interesting, and the sealing can be performed without applying glue, so that troublesome labor can be saved. Further, similarly to the envelope according to the first embodiment, when opening the sticker, the sticker 3 is not peeled off by the dotted-line cut 2d formed around the sticker 3 and remains attached to the envelope body 1 without peeling. As a result, unauthorized opening by anyone other than the legitimate recipient is prevented.

(3) Description of Second Modification of First Embodiment The envelope according to the second modification of the first embodiment shown in FIG.
The difference from the envelope of the first embodiment is that the cut 2c into the flap 2 is not formed at least at one end (the cut 2c is not formed at both ends in the illustrated example).

When the envelope is sealed, the release paper 5 is peeled off from the flap 2, the uncut portion between the end of the flap 2 and the cut 2c is cut off, and the cut off portion 2b is cut off from the sticking portion 2a. Later, sealing is performed.

The envelope according to the second modification can be manufactured in the same manner as the envelope according to the first embodiment. However, the etching blade 24 provided on the roller 22 of the flap notch processing unit 6i is different from the attachment unit 2a. The cutout 2b is set to a length that does not completely separate it. That is, in the present embodiment, the length of the blade 24 formed on the shaft of the roller 22 is made shorter than that of the first embodiment, so that the flap 2 can be formed so as not to cut a part thereof. In addition, cut 2
The length where c cannot be inserted can be set variously.

According to the envelope according to the second modified example, the same effect as that of the envelope according to the first embodiment can be obtained, and in addition, the flap 2 can be formed without making a cut 2c in a part thereof. In addition, it is possible to avoid a situation in which the separation portion 2b or the release paper 5 is peeled off due to the envelope being in contact with another envelope before the sealing and the adhesive 6 of the sticking portion 2a is exposed.

(4) Description of Second Embodiment Next, a second embodiment of the present invention will be described. The envelope according to the second embodiment shown in FIG. 14 has an envelope body 1 and a flap 2 ′ provided at the envelope opening, similarly to the envelope according to the first embodiment. As described above, the flap 2 ′ is folded on the back side of the envelope body 1 and sealed with glue. However, the flap 2 ′ is different from the flap 2 according to the first embodiment as shown in FIG.
No separating portion 2b is provided.

Incidentally, also in the envelope according to the second embodiment, an apparent sticker portion 3 'is provided by printing an appropriate pattern, character or the like integrally with the flap 2'. The sticker portion 3 'is partially formed so as to protrude from the flap 2'. In the example shown in FIG. 14 or FIG.
Plum flower pattern flap 2 'as sticker part 3'
And two of the petals protrude from the flap 2 '.

The sticker portion 3 'formed to project is
When using the envelope, the flap 2 'is used as shown by the arrow in FIG.
On the back side 1'a of the envelope body 1 ',
It is arranged so as to be stuck over the envelope body 1 'and the flap 2', and has an appearance as if the flap 2 'was sealed using a separate sticker made with a plum blossom design. .

The envelope according to the second embodiment formed as described above can be manufactured in the same manner as the envelope according to the first embodiment. According to the envelope according to the second embodiment, by previously forming the sticker portion 3 'integrally with the flap 2', the operation of attaching a separate sticker at the time of sealing can be omitted, and the sticker can be separately attached. The same decorative effect as in the case of sealing can be obtained.

(5) Description of First Modification of Second Embodiment Next, some modifications of the second embodiment of the present invention will be described. First, the envelope according to the first modification is shown in FIG.
As shown in (a), the sticker portion 3 'is a flap 2'
Is formed without protruding from the inner region, that is, the flap 2 ′.

In this example, as shown in FIG.
By folding the flap 2 'on the back side 1'a of the envelope body 1', the sticker portion 3 'is arranged as if it was stuck on the flap 2'.

The envelope according to the first modified example formed as described above can be manufactured similarly to the envelope according to the first embodiment. According to the envelope of the present example, the same effect as that of the envelope according to the second embodiment can be obtained, and since the sticker portion 3 'is formed in the inner region of the flap 2',
Of course, it never cuts.

(6) Description of the Second Modification of the Second Embodiment Next, the envelope according to the second modification shown in FIG. 17 or FIG. A window 4 is formed. A printing portion 3 "is printed on the back side 1'a of the envelope body 1 'at a portion to which the flap 2' is to be attached, corresponding to the window portion 4. The printing portion 3" has the above-described embodiment. Sticker part 3, 3 'according to form
A pattern, a character, and the like are printed in the same manner as in.

The envelope shown in FIG.
The envelope shown in FIG. 18 has two windows 4 and each window 4 in a semicircular flap 2 ′. It has two printing units 3 ″ corresponding to the unit 4. According to the envelopes shown in FIGS. 17 and 18, when the flap 2 'is stuck, the picture, characters, and the like of the printing section 3 "are exposed through the window section 4. Therefore, the photograph of the face of the parents and the child is printed. You can print it on copy 3 "
By printing the pictures of the groom and the bride on the printing unit 3 ″ and using them as invitations for parties and weddings, an interesting decorative effect can be obtained.

The envelope of this embodiment can be manufactured in the same manner as the envelope according to each of the above-described embodiments. For example, in the flap processing section 6h, since the window section 4 is formed on the flap 2 ', the window is formed on the roller 22. The window portion 4 can be formed in a portion to be the flap 2 ′ by providing an etching blade having the contour of the portion 4 and passing the paper between the rollers 22 and 23.

According to the envelope according to the second modification, the decorative effect of the envelope having a three-dimensional effect can be obtained, and the designed printing portion 3 ″ is integrally formed on the envelope main body 1 ′. Therefore, when a sticker is separately attached, the sticker does not come off or come off in contact with another envelope or the like.

In the envelope shown in FIGS. 17 and 18, the window portion 4 is formed entirely in the inner region of the flap 2 ', but the window portion 4 has a recess formed by cutting off the periphery of the flap 2'. In addition, a printing portion 3 ″ may be provided on the envelope body 1 corresponding to the window portion 4 including the cutout portion (not shown). For example, a window formed by cutting off the end of a flap in a half-moon shape The full moon-shaped printing portion 3 ″ provided on the envelope body 1 corresponding to the portion 4 exposes the full moon-shaped printing portion 3 ″ when the flap is attached, and the flap and the envelope body are used as if using a sticker. Can be presented as if they were sealed across.

The same effect as that of the envelope shown in FIGS. 17 and 18 can be obtained by such an envelope in which the end of the flap 2 'is cut off to form a recess and the printing portion 3 "is exposed in the recess. .

(7) Description of Third Modification of Second Embodiment The envelope according to the third modification shown in FIG. 19A is similar to the envelope according to the second embodiment (see FIG. 14). A part of the sticker portion 3 'is formed so as to protrude from the flap 2'. As shown in FIG. 19A, another sticker portion 3 'having an appropriate design printed in the area of the flap 2'.
a, and a through hole or window 4 formed by cutting off a part of the flap 2 'is formed inside the sticker portion 3'a.

As shown in FIG. 19 (a), a printing portion 3 "is printed on the back side 1'a of the envelope body 1 'at the portion where the flap 2' is attached, corresponding to the window portion 4. The printed portion 3 "can be formed in the same shape as the cut-out portion of the sticker portion 3'a, but is printed in a belt shape in this example. The printing unit 3 ″ can be colored using a color (eg, green) different from the kanji of pine and bamboo, for example.

When using the envelope, as shown in FIG. 19 (b), when the flap 2 'is folded toward the envelope side, the printed portion printed through the window portion 4 on the back side of the envelope corresponding to the window portion 4 is printed. 3 "is exposed. The window 4 may be formed by cutting out the entire pine and bamboo characters.

According to the envelope according to the third modified example, the stickers 3 ', 3'a, the printing section 3 "and the window 4 are appropriately combined so as to be apparently sealed with a sticker. With the appearance as described above and the appearance of the printing portion 3 ″ through the window portion 4, a decorative effect with a three-dimensional effect can be obtained.

(8) Other Modifications In the above description of the first embodiment, the cut line for preventing unsealing shown in FIG. 1 has been described as being formed along the contour of the sticker portion 3. A cut line for opening prevention may be formed in 3. FIG.
6 (a), a perforated cut line for preventing opening may be formed along the outline of the sticker portion 3 'printed in the area inside the flap 2'.

Further, the case where the cut line for opening prevention is formed in a dotted line has been described. Alternatively, a plurality of holes having a relatively large diameter may be formed intermittently to collect a plurality of holes. Alternatively, a cut line for opening prevention may be formed. In this case, when the envelope is opened, the breakage of the connecting portion between the holes can be emphasized to an unauthorized person, and the effect of preventing the opening becomes more remarkable.

Although an example of the bag manufacturing process according to the present invention has been described with reference to FIG. 5, it is not necessary to follow this process. For example, the process of the bottom lid gluing section 6j may be performed before the process of the flap processing section 6i. The processes that can be performed in one of the plurality of processes illustrated in FIG. 5 may be performed collectively. As a method of applying glue to the flap 2, a hot melt adhesive may be sprayed from a nozzle. Further, in the above description, the case where the flap 2 is processed in a series of steps of manufacturing the envelope is taken as an example. However, after manufacturing the normal envelope, the flap 2 is additionally processed. You may. Also with glue,
The sticker part 3 etc. are printed by printing (offset, letterpress, letterpress, etc.) on the envelope made with the tape, etc.
Next, a cut 2c or a dotted cut 2e may be made.

Here, an example in which the sticker portion of the present invention is formed on a flap of a normal envelope will be described with reference to FIG. 20. For example, first, as shown in FIG. Is used to move the glue from the glue tank 17 to glue the flap 2 of each of the manufactured ordinary envelopes. Here, a sponge 16b is provided on a roller 16a for applying the glue to the flap 2 of the roller bearing 16, and this sponge 16b absorbs the glue sent from the glue tank 17 from another roller 16c and applies the glue to the flap 2. I do. Therefore, the glue is applied to the flap 2 in a rectangular shape in contact with the sponge 16b.

Then, the release paper 5 is pulled out from the roll 18a and cut to a length to be attached to the flap 2, and the cut release paper 5 adheres to the roller 18b by vacuum.
