Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a carrier bag made of a synthetic resin material such as a synthetic resin sheet (film).

[Prior Art] In recent years, synthetic resin carrier bags have been widely used as storage bags for various products and various kinds of luggage. . That is, in the conventional carrier bag, a handle part 3 formed of a flexible string-like or band-like synthetic resin is placed at a predetermined position on the edge of the top opening 2 side of the bottomed storage part 1, and an eyelet part 4 is provided. Alternatively, it was attached in a substantially inverted U-shape via a heat seal portion (not shown).

[Problems to be Solved by the Invention] However, such conventional carrier bags have the following various drawbacks. That is, the handle portion 3 has flexibility and is formed into a substantially inverted U-shape, making it difficult to hold. In addition, since the handle portion 3 is flexible, the load is concentrated on some fingers, resulting in pain in the fingers.

Furthermore, the conventional carrier bag has the disadvantage that it is difficult to attach the handle part 3 to the storage part 1, the productivity is low, and it cannot be provided at a low price.

Moreover, since the handle part 3 is attached to the storage part 1 by an eyelet part 4 or a heat seal part (not shown), when a heavy item is put into the storage part 1, the load is concentrated on the eyelet part 4 or the heat seal part. However, there is a risk that the eyelet portion 4 and the heat seal portion may be damaged and the handle portion 3 may come off.

The purpose of the present invention is to overcome the various drawbacks mentioned above, and to provide a carrier bag that is easy to hold, applies a load evenly to the fingers, is easy to process, and can be provided at low cost.

[Means for Solving the Problems] The present invention forms double edges of synthetic resin bag material at the front and rear sides of the top opening side of the bottomed storage section, and also forms edges on both sides of these edges. A cutout part is formed by punching out the part including the side seal part, and a rod-shaped member of a predetermined length is inserted into each of the edges, and a substantially L-shaped or inverted L-shaped seal part is used to prevent the cutout part from coming out. Furthermore, a notch for gripping the rod-shaped member is provided at the edge adjacent to the center of the rod-shaped member, and this improves the ease of holding the rod-shaped member, and also improves the ease of holding the rod-shaped member and the synthetic resin material and its end. The object is to achieve the above object by improving the ease of processing by changing the shape of the part.

Here, the rod-shaped member may be exposed by the notch, or may not be exposed and may be covered with a synthetic resin material forming an edge.

[Example] Hereinafter, an example of the carrier bag according to the present invention will be described based on the drawings.

An embodiment of the present invention is shown in FIGS. 2 and 3, and in these figures, a storage section 1 made of synthetic resin is shown.
has a bottom portion 11 that is folded inward, and both side portions are welded by side seal portions 12.

The edge 1A of the storage portion 1 on the side of the top opening 2 is folded back to make the bag material double, and includes a side seal portion 12 so that two protrusions 13 having a predetermined interval are formed. It is punched out.
These two protrusions 13 have the side seal portion 1
2 is formed by the punching, and both ends of the rod-like member 14 serving as a handle are inserted into each cut-out portion 13A.
is approximately L provided close to this rod-shaped member 14.
It is fixedly secured by a seal portion 15 in the shape of a letter or an inverted L shape.

This rod-shaped member 14 is formed by cutting a pipe, rod, etc. made of synthetic resin such as polyvinyl chloride, polystyrene, polyethylene, or polypropylene into a predetermined length. The central part is formed by the two protrusions 13
It is configured to be exposed through a gripping notch 16 formed therebetween.

Note that the length of the rod-shaped member 14 is the length of the bottom portion 11 along the longitudinal direction of the rod-shaped member 14 when the top opening 2 is expanded, as shown in FIG.
It is preferable that the length is approximately the same as that of the length.

Next, an example of the manufacturing method of this embodiment configured as described above will be explained with reference to FIGS. 5 to 11.

As shown in FIG. 5, a so-called gazette tube 22 made of synthetic resin is shown in FIG. As shown in FIG.
1 (see Figure 8).

The folded part 21 on one end side is cut out, while the folded part 21 on the other end side is not cut out and is used as the bottom part 11.As shown in FIG. The side seal portion 12 is welded over the entire width in the direction.
is formed.

After this, as shown in FIG. 10, two protruding pieces 13 having a predetermined interval and these protruding pieces
It is punched out to form a bag body 25 having a notch 16 formed in between and having the length of one bag. (see FIG. 11). At this time, the front and rear edges of the cut folded portion 21 constitute a double edge 1A in which the bag material is folded back.

The rod-shaped members 14, each of which has both ends inserted into the protrusion 13, are fixedly attached to each other through seal portions 15 provided in the protrusion 13 in a substantially L-shape or an inverted L-shape so that they cannot fall off, as shown in FIG. - The carrier bag of this example as shown in FIG. 4 is formed.

According to this embodiment, the following effects can be obtained.

Since the rod-shaped member 14 is used as the handle, it is extremely easy to hold compared to conventional carrier bags, and when gripping the handle, the load is not concentrated on only some fingers, and the load is distributed over all the fingers. Load is applied evenly. Therefore, unlike conventional carrier bags, some fingers do not become sore when gripping the handle.

Moreover, a rod-shaped member 14 whose handle portion has a predetermined length
Since the bag is formed by the bag, it has the effect that the bag does not lose its shape even when the baggage is put in the storage section 1.

Furthermore, unlike conventional carrier bags, the load is not concentrated on the eyelet part 4, which is the joint between the storage part 1 and the handle part 3, and the joint is not damaged. This has the effect of providing a durable carrier bag. At this time, the upper end side of the edge 1A into which each rod-shaped member 14 is inserted is the position where the greatest load is applied, but in this embodiment, since this upper end side is formed by folding back a sheet of bag material, the upper end side It has greater strength than one whose sides are formed by welding, and from this point of view it can be made into a durable carrier bag.

In addition, when loading and unloading items into the storage section 1, since the two rod-shaped members 14 are arranged over a long range of the top opening 2, simply separating the rod-shaped members 14 from each other by an appropriate distance is enough. The top opening 2 can be easily opened to a large size, making it possible to take items in and out of the storage section 1 very easily and quickly (see FIG. 4).

Furthermore, since the seal portion 15 is provided close to the rod-shaped member 14, it is possible to effectively prevent the rod-shaped member 14 from moving or falling off.

In addition, according to this embodiment, not only is processing easy, but continuous production is possible and productivity is high.
It is effective because it can be provided at a low price. At this time, since the rod-shaped member 14 can be inserted into the protruding piece 13 from the cutout portion 13A, the insertion is easy and the workability can be improved.

Note that the shape of the protruding piece 13 and the notch 16 formed by punching out the edge 1A on the side of the top opening 2 is not limited to the shape shown in FIG. 2, but may be, for example, as shown in FIG. 12. In some cases, the protruding piece 13 is provided with an inclined cutout 13A on the side seal portion 12 side, or as shown in FIG. An arc-shaped cutout portion 13A may be formed on the side seal 12 side of the piece 13.

Furthermore, the substantially central portion of the rod-shaped member 14 has a notch 16.
The rod-shaped member 14 does not need to be exposed.
is surrounded by the folded end edge 1A of the storage portion 1 and is engaged by a substantially L-shaped or inverted L-shaped seal portion 15, and the end edge 1A adjacent to the substantially central portion of the rod-shaped member 14 A notch 16 may be formed in the hole.

In addition, although the rod-shaped member 14 has been described as being made of synthetic resin, it is not limited to synthetic resin, and may be made of wood, paper, etc.
Alternatively, it may be made of other materials such as synthetic paper. However, if it is made of synthetic resin, it has the advantage of good workability and productivity.

[Effects of the invention] As described above, the invention has the following effects.

That is, by using the rod-shaped member as the handle, it is easy to hold without causing pain in fingers due to unbalanced load, and the bag does not lose its shape. Furthermore, there is no damage caused by concentrated loads on the eyelet, which is the case in the past, and the strength can be increased by double folding. Furthermore, the use of a rod-shaped member makes it easy to open the bag, and when inserting into the edge of the rod-shaped member, it is also possible to insert it from the cutout, making it easy to manufacture and inexpensive, and moreover, it is approximately L-shaped. Or reverse L
The shaped seal portion effectively prevents the rod-shaped member from coming off.
