DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net bag made of synthetic resin and mainly used for shipping onions and other vegetables and grains.

[0002]

2. Description of the Related Art Net bags made of synthetic resin are mainly used for shipping onions and the like.
Onions or the like of which size is selected are usually stored in about 20 kg and shipped. Conventionally, in the handling work such as small transport and unloading of the bag, the binding part by the closing string at the bag mouth and the corner of the bag bottom are grasped with both hands, or the trunk is held with both hands. Although it was lifted, the weight of the stored contents was quite large, and it was difficult to grip the bottom of the bag, so the hand slipped and dropped, damaging the contents and reducing the product value. There was a problem.

Therefore, it has been proposed to attach a hand made of a band-shaped piece to a mesh bag made of a synthetic resin thread at the center of the bottom of the bag by means of suturing means (for example, Japanese Utility Model Publication No. 7-47336). ).

[0004] By the way, a conventional hand attached to this main mesh bag is a woven fabric obtained by slitting a synthetic resin film into a tape-like yarn and using it for warp and weft, or the tape-like yarn. A strip is used which is made of a sheet in which the yarns are crossed in the course of the process and joined at the intersections by means of fusion or the like, or other films are overlapped and joined.

When the end of the strip is sewn to the bottom of the bag by sewing or the like, one of the tape-like threads, for example, a weft thread, is parallel to the sewing section, and a number of sewing holes are continuous. There is a problem in maintaining the strength of the sewn portion because the material is scratched and the material is damaged.If the suturing portion is pulled with a strong force, the sewn portion of the strip may be torn and the handle may be cut. Was.

[0006] In particular, even when a carrying hand is provided at the bottom of the bag, it is desirable to hold the binding portion at the mouth of the bag and the carrying hand at the bottom of the bag and carry it up when carrying it. In some cases, the user may carry the product by holding only the bottom hand, so that a strong force may be applied to the hand to cause breakage and drop the bag.

In order to increase the strength by increasing the thickness of the strip used for the carrying hand or devising the suturing structure, the manufacturing cost increases and the net bag used for shipping onions or the like is used. Is not practical in terms of profitability.

[0008] The present invention has been made in view of the above, and as a net bag with a hand to be used for shipping onions and other vegetables and cereals, the strength of the hand is increased without increasing the cost. It is intended to provide a net bag which can be used without fear of breakage of a sewn portion or the like and which is easy to handle during transportation or the like.

[0009]

According to the present invention, there is provided a net bag with a handle, which is formed by a mesh knitted with synthetic resin yarns, and is attached to a part of the bag body. A net bag to which a hand is attached, wherein the hand is
It is made of a belt-shaped warp knitted fabric knitted with a synthetic resin monofilament yarn, and both ends in the longitudinal direction are stitched and attached to the bag body.

[0010] In this net bag with a hand, since the hand attached to the bag body is made of a warp knitted fabric of a synthetic resin monofilament thread, even if it is sewn to the bag body by sewing, The needle of the sewing machine is sewn through the synthetic resin monofilament yarn constituting the warp knitted fabric, and does not damage the material of the warp knitted fabric itself. In addition, many monofilament yarns with higher tensile strength than the spun yarn are entangled with each other by the knitting structure and are continuous in the knitting direction, so that even if a strong force is applied to the stitched part, it will easily break or break. There is no. In addition, the hand of the warp knitted fabric, even those with little growth,
It also has the effect of reducing the shock applied to the hand holding the bag when lifting the bag.

The above-mentioned hand is preferably a warp-knitted fabric having a warp-knitted structure with little elongation in the warp direction and knitted in a warp-wise belt shape. Thereby, excessive elongation of the hand when the bag is lifted can be restricted, and furthermore, breakage or breakage of the monofilament yarn continuous in the longitudinal direction is more unlikely to occur.

Further, the belt-shaped warp knitted fabric is knitted with a relatively coarse knitting structure having a warp knitting structure formed by a large number of stitch rows in a warp direction and an insertion yarn traversingly inserted over a plurality of stitch rows. Above is particularly preferred. That is, with this configuration, the needle of the sewing machine for sewing can easily pass between the monofilament threads, and the sewing can be easily and reliably performed without damaging the warp knitted fabric.

Further, both ends in the longitudinal direction of the hand made of the belt-shaped warp knitted fabric may be folded back, and the folded ends may be integrally sewn to the bottom of the bag body. This further increases the strength of the suturing portion,
It can be attached without fear of causing breakage, and it is easily possible to sew the bag body at the same time as the bottom of the bag body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the embodiments shown in the drawings.

FIG. 1 shows a net bag with a handle according to the present invention.
FIG. 2 is an enlarged view of an attached portion of a hand, FIG. 3 is an enlarged view of a part of a belt-like warp knitted fabric used for the hand, and FIG. It shows a diagram in use.

In the figure, a synthetic resin net bag (A)
As is well known, the bag body (1) is formed of a net-like knitted fabric knitted using synthetic resin yarns such as synthetic resin monofilaments such as polyethylene as constituent yarns. Is a closing cord (12) for closing the mouth (11)
Is inserted and attached to the edge of the opening where the bag is sewn.
The bag bottom part (13) is closed by knitting the knitted fabric constituting the bag body (1) in half, sewing it by overlock sewing, or the like. (2) shows the stitched portion. A hand (3) is attached to a part of the bag body (1), mainly at the center of the bag bottom (13) by suturing means.

The above-mentioned hand (3) has a required width formed by warp knitting with a Raschel machine using a synthetic resin monofilament yarn such as polyethylene similar to the yarn constituting the bag body (1). It consists of a belt-shaped warp knitted fabric (30). As the warp knitted fabric (30), a warp knitted structure is used in which a strong tensile force is applied, and the warp knitted structure is particularly knitted in a warp-knitted structure with a structure which is less elongated in the warp direction. Is preferred.

As the warp knitted fabric (30) having such a knitting structure,
As shown in FIG. 3, a large number of stitch rows (31) formed by chain stitches extending while forming stitches in the warp direction are traversed and inserted across a plurality of stitch rows (31) so as to connect these stitch rows (31). A warp knitted fabric knitted with a relatively coarse knit by the warp knitting structure with the insertion yarn (32) can be exemplified.

When the knitting is relatively coarse, the sewing needle easily passes between the threads when sewing the sewing to the bag body (1), and the material is hardly damaged. Also, the amount of yarn used can be reduced, and the cost can be reduced. Of course, as long as the elongation in the warp direction can be appropriately suppressed, implementation using various warp knitting structures other than those described above is possible.

The attachment form of the hand (3) to the bag body (1) by the belt-like warp knitted fabric (30) is, for example, that the warp knitted fabric (30) is folded in two at the center in the longitudinal direction. It is also possible to sew together the bag bottom (13) in a state where both ends are overlapped. However, in the case of the illustrated embodiment, the belt-shaped warp knitted fabric (30) is attached to both ends in the longitudinal direction. (30a) Central part (30b) so that (30a) is parallel
And bent at substantially right angles to the both ends (30a)
The end of (30a) is folded back and this folded end (30
c) (30c) is integrally sewn to the bag bottom (13) simultaneously with the bottom stitch by sewing.

Both ends (30a) (30) of the warp knitted fabric (30)
It is possible to sew without folding back a), but it is preferable to fold and sew as shown in the figure from the viewpoint of maintaining the strength of the sewn portion.

As the constituent yarn of the warp knitted fabric (30) used in the hand (3), a monofilament yarn of 150 to 500 denier, preferably 200 to 400 denier is suitably used. Depending on the weight and the capacity of the net bag, a thread having a thickness other than the above may be used. Further, the warp knitted fabric (30) is not limited to a single layer as shown in FIG.
Although it is possible to fold it at the center in the width direction to form two layers or to use a plurality of layers, it is possible to use the monofilament yarn even if it is a single layer as shown in the figure.

Further, it is preferable to sew the carrying hand (3) at the same time as the bottom sewing of the bag body (1), because sewing work in manufacturing is easier. However, it is preferable to sew it separately from the bottom sewing. It is also possible. In addition, the attachment point of the hand (3) is not limited to the central portion of the bag bottom (13) as shown in the figure, but may be attached to the vicinity of the corner of the bag bottom (13). In the case of a side-sewn type net bag, the hand may be stitched and attached to the side to be sewn.

The mesh bag (A) configured as described above stores vegetables such as onions as shown in FIG. 4, for example, and closes the bag mouth (11) and binds it with a string (12) for use. I do. Then, when lifting the bag in handling work such as transportation, the binding portion of the bag mouth (11) with the binding string (12) and the bag bottom (13)
By grasping the carrying hand (3) attached to the vehicle, it can be easily lifted.

At this time, the hand (3) made of a warp knitted fabric made of a synthetic resin monofilament yarn has a smaller shock than a woven fabric or the like, even if the hand has the hand (3). Can be softened. Moreover, if it is knitted in a warp knit structure with a warp knitting structure with little warp elongation,
Excessive elongation at the time of lifting can be regulated, and it can be used without problems as a carrier.

[0026] Further, since the hand (3) is made of a warp knitted fabric knitted with a relatively coarse warp knitting structure using a monofilament yarn, the needle of the sewing machine for suturing the hand (3) holds the warp knitted fabric. It passes between the constituent synthetic resin monofilament yarns, and does not damage the material of the warp knitted fabric (30) itself, that is, the monofilament yarn. In addition, monofilament yarns have higher tensile strength than spun yarns and films, and many monofilament yarns are entangled by the knitting structure and are continuous in the knitting direction.
Even if a strong force is applied to the suturing portion of the hand, it does not easily break or break. In particular, when the warp knitted fabric is knitted in a belt shape with a small elongation in the warp direction, the warp knitted fabric itself has a high tensile strength in the longitudinal direction, and can maintain sufficient strength for use as a carrying hand. Therefore, the strength of the hand is higher than that of the hand made of a known sheet material, and the bag can be prevented from dropping due to the break of the hand during use.

Further, the hand (3) made of a warp knitted fabric can be easily manufactured by warp knitting, the material cost can be reduced by knitting with a coarse knitting, and sewing can be performed simultaneously with sewing at the bottom of the bag body by sewing. Can be attached and the manufacturing cost does not increase.

[0028]

As described above, according to the net bag with a handle according to the present invention, the strength of the hand is increased without increasing the cost, and it is used without any risk of breakage of the sewn portion or the like in handling work such as transportation. It can be suitably used as a net bag for shipping onions and other vegetables and cereals.
