Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a packaging bag for storing flat service items, souvenirs, etc.

[Prior art and its problems] Synthetic resin pouches for storing flat service items, souvenirs, prizes, gifts, etc. when distributing them are well known. Although such pouches have space to print company names, trademarks, service marks, etc., it is impossible to print the amount of type that is listed in general guidebooks.

Therefore, when advertising and explaining new products or services, etc. by distributing service products, pamphlets, etc.
Unless a separate large bag is prepared that can store the business cards, etc. of the person in charge and the service items stored in the small bag all at once, these items will be separated after being delivered to the customer, resulting in insufficient advertising and explanation capabilities. I can't. However, preparing a separate bag and storing the items all at once is complicated and uneconomical.

Another method would be to make the pouch transparent and place a pamphlet or the like together with a service item or the like in the pouch. However, if there are a wide variety of products and services to be introduced, and if business cards of each person in charge are also included, it is very time-consuming to sort and stuff them into bags.

An object of the present invention is to provide a packaging bag that can easily attach pamphlets, business cards, etc. to service products.

[Means for Solving the Problems] The packaging bag of the present invention has a front surface and/or a synthetic resin packaging body.
Alternatively, a synthetic resin tape piece having the same width as the main body is provided on the back side, and both side edges of the tape piece are integrally welded to both side edges of the main body.

[Function] Since tape pieces are provided on the front and/or back of the main body, pamphlets, business cards, etc. can be easily inserted and attached here, and it is also easy to take them out when necessary.

Further, since the tape piece has the same width as the main body, it is possible to weld both sides of the bag main body and at the same time weld them together.

【Example] Next, embodiments of the present invention will be described with reference to the drawings.

Figures 1 to 3 show an embodiment of the packaging bag (1) according to the present invention, in which a synthetic resin packaging body (2) is provided with a bag of the same width as the packaging body (2) on the front and back sides. Transparent tape pieces (3) and (4) made of synthetic resin are provided. These tape pieces (
3) (4) is made of a transparent film,
Its side edges are integrally welded to both side edges (5) and (6) of the mounting body (2). Therefore, in FIG. 3 showing the cross section of the tape portion, the film (7) forming the packaging body (2) is
) (7) and films (8) and (9) forming the front and back tape pieces (3) and (4), a total of four layers of film appear, and these are welded together at both side edges (5) and (6). . A pamphlet or the like can be inserted between the front tape piece (3) and the main body (2) and between the back tape piece (4) and the main body (2).

As mentioned above, if the tape pieces (3) and (4) are made of transparent film, pamphlets, etc. can be printed on the tape pieces (3).
(4) Necessary information can be read without having to take it out one by one, and the advertising effect of pamphlets etc. will not be impaired even if it remains inserted into the tape piece. Furthermore, if a trademark or the like is printed on the main body of the case, it will have an advertising function even if the pamphlet or the like is taken out.

In addition, in this example, the front tape piece (3) is replaced with the back tape piece
4) It is better formed, and the front tape piece (3) can be used for relatively long items such as pamphlets and catalogs, and the back tape piece (3) can be used for relatively long items such as pamphlets and catalogs.
4) is suitable for inserting relatively short items such as business cards and memos. However, the length of the front and back tape pieces is not limited to this, and can be changed as appropriate depending on the quality of the pamphlet, etc., the purpose of the bag, etc.

For example, although not shown, it is possible to make the lengths of the front and back inner tape pieces the same, or to make the back tape piece longer than the front tape piece. Further, if it is necessary to insert a pamphlet or the like into only one of the front and back sides of the main body, a piece of tape may be provided only on one side.

Figure 4 shows that the lower ends of the front and back tape pieces (3) and (4) are folded and turned toward the mounting body (2) (10) and (11).
An example is shown in which these tape pieces (3> (4) are arranged on the front and back sides of the packaging body (2) so as to be shifted in the vertical direction.

By providing the flaps 10) and (11) in this manner, the inserted pamphlet, etc. can be inserted into this flap part, and the pamphlet, etc. will not fall out. In addition, the folding section 10) Hl) and the mounting body (2) are not welded together except for the above-mentioned side edges (5) and (6), and it is also possible to insert another pamphlet or the like between them. be.

In this example, the folded length is shortened, but it is also possible to lengthen the folded length so that it has the same length as the tape piece. It is also possible to make it longer than the tape piece (3). Fifth
In the case shown in the figure, it is easy to insert pamphlets and the like.

In the embodiment shown in FIG. 6, the tape piece (3) has 10 folds not only at the lower end but also at the upper end toward the mounting body (2).
) (12). Tape pieces (3
), it is possible to reliably attach labels, business cards, etc. by inserting folded sections 10) and (12) at both the upper and lower ends of the section. In other words, if it is a label or the like that has a length slightly shorter than the longitudinal length of the tape piece (3) and a width shorter than the width of the bag (1), the tape piece (3)
) can be easily inserted by folding the top and bottom of (12) (10) apart a little to the extent that it does not tear. Furthermore, after insertion, the upper and lower ends of the label are securely stopped by the upper and lower folds 12) (10) of the tape piece (3), and will not come off. The packaging bag (1) provided with such a tape piece (3) is particularly preferable when it is necessary to prevent labels etc. from falling off from the bag, such as analytical sample storage bags or prescription drug storage bags. .

The tape piece (3) shown in FIG. 7 has both upper and lower ends folded back in the direction opposite to the main body (2).

Fold it back towards the outside of the bag like this 1G) (12
), it is easy to take out the label etc. as needed, and it is also possible to write the necessary information while inserting the label etc. into the folded parts 10) and 12).

Although FIGS. 5 to 7 show only the front side of the bag for convenience, it is also possible to provide such a folded tape piece on the back side of the bag. Further, the position at which the tape pieces are attached can be changed as appropriate in the vertical direction, and it is also possible to provide two or more tape pieces on one side of the bag.

The packaging bag (1) shown in FIG. 8 has a tape piece (3) formed into a trapezoidal shape, but it is also possible to form the upper part of the tape piece into a wave shape.

In the packaging bag (1) according to the present invention, the means for closing the opening at the top of the bag body is not particularly limited. In other words, any means normally used for closing synthetic resin bags may be used, but for example, as shown in FIGS. 1 and 2, among the films of the packaging body (2), The front side is longer than the back side, and the opening of the bag body is formed in different steps, and an adhesive part (14) made of adhesive or adhesive tape is provided on the protruding tongue piece (13) of the front film, and this is attached to the back film. It may be folded back and attached, or as shown in Fig. 4, a zipper (
15) may be closed.

Furthermore, when the main body (2) is also made of a transparent film, it is convenient to use because the contents stored in the main body (2) can be determined at a glance.

Next, an example of a method for manufacturing a packaging bag according to the present invention will be described.

In Fig. 9, (16) is a raw roll wrapped with synthetic resin film (7), which is the material of the packaging body (2), and (17)
and (18) are raw rolls wrapped with transparent synthetic resin films (8) and (9), which are the raw materials for tape pieces (3) and (4).
(8) (9) is sent out. Tape piece (3)
The raw fabric rolls (17) and (18) for (4) are coaxial,
Since they are arranged with a slight gap in the width direction, the two synthetic resin films (8) and (9) sent out are on the same plane and parallel to each other. The above three films (7)
(8) and (9) merge at the direction change roll (19) to form a double film and are sent upward. In this state, as shown in a, there is a wide film (7) for the mounting body.
2 narrow strips of film (8) for the tape strips (9)
) are overlapped. Then, add the film for the tape piece (8
) Depending on the width of (9), each tape piece (3) (
4) The length is determined.

Next, the film in this state <7><8)
(9) is transferred downwards via the deflection roll (20). At this time, a folding guide plate (21) is provided along the feeding path of the film (7), (8), and (9), and this folding guide plate (21) has an inverted triangular shape (no. (see Figure 10), film (7) (8)
(9) is bent along both side edges (22) (22) of the guide plate (21) as it is fed, and when it passes through the direction changing roll (23) at the lower end, it is completely folded into four layers. A polymerized film (24) is obtained. In that case, use two synthetic resin films for tape pieces (8) (9)
It is folded in two between.

Next, this polymerized film (24) is sequentially rolled onto a base roll (25).
) (26), and when it stops, as shown in FIG. 11, the hot iron (21) is used to fuse the entire width. By this fusing, the polymer film (24) is separated at each width of the packaging bag (1), and the packaging body film (7) is separated at both sides of the bag.
(7) and tape piece films (8) and (9) are welded together.

In this way, instead of welding and separating at the same time, first weld the polymeric film (24) to form a wide weld line at the same locations as above, and then cut the center of the width of the weld line. You may.

In the embodiment of FIG. 10, the film (7) (
8) The folding line (28) when (9) is folded in half by the folding guide plate (21) is
) does not match the center line of the width. That is, in the packaging body film (7), the portion on the right side of the fold line (28) (corresponding to the front side film) is longer than the portion on the left side (corresponding to the back side film) by the length of the tongue (13). Also, the widths of the tape piece films (8) and (9) are not the same;
The film (8) on the right side of the fold line (28) (corresponding to the film for the front side tape piece) is wider than the film (9) on the left side (corresponding to the film for the back side tape piece). Folded guide plate (
21) If the relative position 1ffi in the width direction of the packaging body film (7) and the tape piece films (8) and (9) and the width of the tape piece films (8) and (9) are adjusted in this way, the A packaging bag (1) shown in FIGS. 1 and 2 is manufactured.

On the other hand, if the center line of the width of the packaging body film (7) is adjusted to match the fold line (28), the front and back films of the packaging body (2) will have the same length as shown in FIG. Also, if the widths of the films for tape pieces (8) and (9) are the same, although not shown, it is possible to
) are formed to the same length.

In addition, like the packaging bag (1) in Figure 4, the tape piece (3)
To form (10) and (11) by folding back to (4), as shown in FIG.
Folding roll (29) with a width shorter than (9)
(30) and pushing pieces <31) (32) that sandwich the films (13) and (9) from above and below may be provided. That is, the tape piece films (8) (9) sent out from the original rolls (17) (18) pass through the folding rolls (29) (3G>, but the tape piece films (8) (9) ), only the negative edge of each
The original fabric rolls (17) (18) protrude outward from the folding rolls (29) (30) by a predetermined length.
) and the folding rolls (29) (30) in the axial direction, the tape piece film (8)
The protruding portion of (9) is the folding roll (2
9) Bend toward one end of (30). This bent piece is folded back by the pushing pieces (31) and (32).
0) (11) is formed.

On the other hand, as shown in FIG. 6, in order to provide folds 12) (10) at both the upper and lower ends of the tape piece (3), the axial direction of the folding roll (29) is determined by
8) so that both side edges of the film (8) protrude outward from the roll (29) by a predetermined length. In addition, as shown in FIG. 7, in order to fold the tape piece (3) in the direction opposite to the packaging body (2), the tape piece film (8) is placed on the folding roll ( 29) so that it passes below.

In the examples shown in FIGS. 9 to 11, the release film that covers the adhesive part (14) of the packaging body film (7) is omitted for convenience, but in actual manufacturing, the release film is not included. A packaging bag (1) is formed with the bag attached, and when used, it is peeled off and the upper opening of the bag body is closed.

Also, like the packaging bag <1) in Figure 4, a zipper (1
In the case of closing in step 5), a film provided with fitting protrusions and grooves on both sides may be used as the mounting body film <7).

In addition, in place of cutting the polymer film (24) in the final step, although not shown, a film for the packaging body (24) is used.
7) and tape piece films (8) and (9) are cut in advance to the same width as the packaging bag (1), stacked on top of each other, folded in half, and welded the edges on both sides to form the packaging bag. may be formed.

In each of the above embodiments, the tape pieces (3) and (4) are formed of transparent films, but the present invention is not limited thereto. It may be formed of a transparent film with characters, patterns, etc. printed on it, or it may be formed of an opaque film, and the means for closing the main body is provided at the top of the main body as in each of the above embodiments. [Effects of the Invention] (1) Since tape pieces are provided on the front and/or back of the packaging body, it can be used to attach pamphlets, business cards, etc. Easy to insert, attach and remove.

(2) Since both sides of the main body and the tape piece can be welded simultaneously and integrally, manufacturing is simple and inexpensive. Furthermore, since there is no additional process to the conventional synthetic resin bag manufacturing process, there is no need to change the manufacturing equipment.
