Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carrier bag, and more particularly to a carrier bag made of a flexible sheet member.

In general, a carrier bag generally has an opening for loading and unloading articles and a grip section on one side of the bag.

A commonly cited example of this type of carrier bag is a carrier bag made of synthetic resin (for example, polyethylene) as shown in FIGS. 1 and 2, which is often found in supermarkets and the like.

That is, the carrier bag 1 shown in FIGS. 1 and 2 (perspective view of FIG. 1) has fold-in portions 11.1 folded inward on both sides.
2 and one end side (lower end side in the figure) is a connecting part 13
The other end side (upper end side in the figure) is connected by a connecting part 14, and a cut 1 is made on the inside of this end part, and the folded part 11.1
A rectangular notch 1 provided to remove a part of 2.
5a. In the carrier bag 1 configured in this way, the storage portion 10 is formed by the folding portions 11, 12 and the connecting portion 13, and the opening 1 is
5 are formed and located on both sides of the notch 15a. The protruding parts 16a and 16b serve as the gripping part 16.

By the way, the carrier bags shown in Figures 1 and 2 above are
3 (Al, (Bl, (C1) and C1. In other words, in FIG. 3 (4), a long tube-shaped sheet 2 is placed between the left and right sides of the figure. As shown in FIG. 6 (Bl), this sheet 2 is folded inward on both sides along the longitudinal direction to form folded portions 11 and 12 and to be flattened. Then, as shown in FIG. 6 (C1), the joint portion 13.1.i is applied using a heat sealing machine or the like, and the separation portions 21 and 22 are cut using a cutting machine or the like to form a rectangular disguise 2a. be done.

After stacking a predetermined number of 50 or 100 sheets of the temporary clasp a, cutouts 15a are cut out using a cutting machine, and the process is completed as shown in FIG. 3) (see FIGS. 1 and 2 above). Bag 1 is manufactured.

Since the retainer V116 is formed on the side part on the side where the joint part 14 is applied, the notch part 15a must be removed as a post-processing as described above (see Fig. 6 (C1)).
, (see DJ diagram), there was a problem in that the number of man-hours for manufacturing increased and the resulting bags were expensive.

Although I have omitted the illustrations, there are other handbags that have a handle attached to the bag body in post-processing, or have a rectangular shape cut out so that you can fit your hand in, but even these require a lot of man-hours to manufacture. There was a problem that it became more expensive.

The present invention has been made in view of the above points, and an object of the present invention is to provide an inexpensive carrier bag that reduces the number of manufacturing steps.

The first invention of the present application, which has been made to achieve the above object, has flexible sheet members stacked one on top of the other and formed into a rectangular shape, and a pair of opposite side portions of one of the sheet members are sealed. The carrier bag is constructed by forming a closed side part and a pair of opposing side parts each having a half-open side part with one end open and the other end closed.

Further, the second invention of the present application is such that a plurality of carrier bags having the structure of the first invention are connected in a separable state at the half-open side portion, and each carrier bag can be easily separated when used. This is an assembly of handbags that can be used for various purposes.

Next, embodiments of the present invention will be explained based on FIGS. 4 to 14. In these figures, the same reference numerals and parts as those in FIGS. 1 to 6 described above are denoted. , so detailed explanations of these forces will be omitted.

First, what is shown in FIGS. 4 to 7 is a carrier bag made of a sheet of synthetic polymer (for example, polyethylene, polypropylene, polyvinyl chloride, etc.) according to the first embodiment of the present invention. . As shown in FIG. 4, this carrier bag has a rectangular shape with a pair of closed sides (bent parts) 1a and 1b and a pair of half-open sides 1c*1d. A pair of half-opening sides 1c and 1dK are provided with connecting parts 16 and welds 14 of different lengths extending from one closed side 1a to the other closed side 1b, respectively. K thus forms half-open side portions 1C and 1d.

Moreover, one closed side s1a side is provided with a folding part 11 folded inward, as shown in FIGS. 4 and 5.

As is clear from the perspective view of FIG. 6, a single carrier bag constructed in this manner has a half-open side portion 1c.

The storage part 10 is formed by the part surrounded by the closing part (joint part 13, 141) in 1d and the folding part 11 in the closing side part 1a. This is the base of 10 (square base).

Further, the portion of the half-open side portions 1c and 1d on the side of the other closed side portion 'Ib' is not connected and can be opened freely, and serves as the opening 15. The portion 1b is pressed against the grip portion 16.

FIG. 7 (Al, Bl shows an example of the carrying bag 10 in use, the length of the closed length and the length of the joint part) are short and wide, and the half-open side 1C side is Opening 1
From the part 5, the article 3 such as canned beer is stored in the storage part 10.
Put it inside. At this time, the closing portion (joint portion 14) at the opposite half-open side portion 1d becomes a wall, and the article 6 can be smoothly placed into the storage portion 10. When the article 3 has been stored, when a finger is inserted into the opening 15 as shown in FIG.

Next, FIGS. 8 and 9 schematically show an example of the manufacturing state of a carrier bag. As shown in FIG. The tubular sheet 2 wound into a shape is continuously rolled out, and a device (not shown, for example, a heat sealing machine) is used to form the joints 13 and 14 and to easily cut each carrier bag 1. The only thing you can do is let go. And when using carrier bag 1,
As shown in FIG. 9, the glove 1 is separated from each perforation 17 by pulling the end and ready for use.

Next, FIGS. 10 to 14 to 1 show carrier bags according to other embodiments of the present invention (2nd, 3rd, 4th, 5th, and 6th embodiments). The explanation will focus on the points that are different from the first embodiment, and the explanation of the common parts will be omitted.

First, FIG. 10 shows a carrier bag 1 according to the second embodiment,
The folding portion 1 is also attached to the portion of the closing side portion 1b where the grip portion 16 reaches.
2.

According to this carrier bag 1, the folding part 12 becomes the gripping part 16, so the opening part 15 is large (such that it is easy to put in and take out articles).Furthermore, as shown in FIGS. This has the advantage that the winding is less likely to be distorted when the winding is done.

FIG. 11 shows a carrier bag 1 according to the third embodiment,
Even if the lengths of the two connecting portions 13 and 14 are the same, this does not cause any inconvenience in putting in and taking out articles, and there are no practical problems. However, it seems that the case where the lengths of the connecting portions 13 and 14 are changed as in the first embodiment makes it easier to insert articles.

Furthermore, FIG. 1.2 shows the carrier bag 1 according to the fourth embodiment, in which a folding part 12 is also provided in the part of the closed side 's1b which becomes the grip part 16, and the part which becomes the bottom of the storage part 1o. The width of the closed side portion 1a is increased to form a trapezoidal shape. According to this carrier bag 1, the storage part 10 is not a scale that can be formed large, but the grip part 16 is small, so that it is easy to hold.

Next, FIGS. 13 and 14 show the strength of the p1 joint portions 13 and 14 of the carrier bag 1 from the left and second embodiments. That is, in the single carrier bag shown in FIG. 16 (Rth Example), the connecting parts 13 and 14 are located slightly inside the edges of the half-open side parts 1c and 1d, and at the inner end in the extending direction. Connecting portion 13 extending in the direction of the edge. ．． 14a
It is configured by providing. In addition, in the carrying bag shown in FIG. 14 (Embodiment Δ), the connecting portions 13 and 14 are connected to two connecting portions 13b, 13c and 14b, 14C, respectively, and the inner ends of these connecting portions in the extending direction. It is formed by connecting portions 13a and 14a extending in the direction of the edge provided on the holder.

In addition, each of the embodiments described above has been described as having a folding part 11 and configured so that this part becomes the bottom (square bottom) of the storage part 10, but this folding part 1
There is no practical problem even if there is no one digit. However, since the folding part 11 has the advantage of widening the bottom and improving the efficiency of storing items, it is desirable to construct a carrier bag with the folding part 11.

Furthermore, the materials forming the carrier bag of the present invention are not limited to the aforementioned synthetic resins such as polyethylene, polypropylene, and polyvinyl chloride, but can also be cloth, nonwoven fabric, or a combination of cloth and synthetic resin (for example, impregnation, coating, etc.). It is possible to use a material made of a composite material (such as a composite material by adhesion), but in short, any material with a high degree of flexibility can be constructed in the same way and produce the same effect.

Furthermore, the fixed parts 13.13a, 13b, 13c, and 14
．． The means for forming the carrier bags 14a, 14b, and 14c is performed by fusing with a heat sealing machine, adhering with an adhesive, or sewing, and is appropriately selected and used depending on the material from which the carrier bag 1 is formed. It is.

As is clear from the above description, the carrier bag according to the present invention has a pair of opposite closed side portions 1a.

1b, and a pair of opposite half-open side portions 1c+1d
Since the opening 15 and the gripping part 16 for putting in and taking out articles are formed on different sides, the carrying bag should be constructed in a simple rectangular shape. and can be manufactured at low cost.

Such a rectangular carrier bag can be manufactured at a lower cost by using a tube-shaped sheet. In other words, by providing a joining part 16.14 in the transverse direction of this sheet and cutting along this joining part, a half-open side part 1 can be obtained.
c, 'ld can be formed, and the closed sides 1a + 1b are formed by the tube itself, so
Compared to conventional carrier bags, the number of manufacturing steps can be significantly reduced, and an inexpensive carrier bag can be obtained.

Alternatively, a plurality of carrier bags may be formed continuously on a sheet, and each carrier bag may not be completely cut, but an aggregate of carrier bags (such as a roll) connected by intermittent cutting parts such as perforations may be formed. It can be configured and the elastic can be easily pulled apart to create individual carrier bags when used, so there is no need to form individual carrier bags in advance.
