Description

[Detailed description of the invention] This invention relates to a large-sized transporter that is used repeatedly when transporting rice grains, fertilizers, and other granular, powdery, or block materials.

Generally, this kind of bag is packed vertically, so it is hung vertically and loaded onto a truck, freight car, ship, etc. When unloading, it is hung vertically and moved directly above a hopper, etc. Since the contents are discharged from the lower end, there is an advantage that the work can be done consistently and the efficiency can be improved.

However, when attaching the sashing edge, it is difficult to increase the strength by constructing a weave structure made of only warp threads with no wefts directly on the main body of the garment, or by providing a string hole and inserting the sashing edge through this. Not only does the main body become weak, but the contents leak from the blind structure, and when the contents are filled, the bottom surface becomes uneven, resulting in a lack of stability.

This proposal was devised to eliminate this drawback,
A ring-shaped pouch-like part is formed on the lower outer periphery of the main body, and the pouch-like part is formed into a blind weave part consisting only of warp threads with the weft removed, or a hole is provided for strings to pass through this weave part or Insert the bag bottom main tightening string into the string passing hole at regular intervals so as to hide it from the front and back alternately, and also insert the bottom tightening string into the same blind tissue part or the string passing hole provided below the bag-shaped part. After inserting a string and pushing the bound part of the buttocks into the bag, the bag bottom can be closed with the bag bottom final tightening string, and a pair of left and right hanging bands are attached. This is a heavy bag that is attached vertically to the side of the main body.

The embodiments shown in the drawings will be described below.

First, see Figures 1 to 11. An explanation will be given starting from the embodiment shown in the figure.

1 is a woven fabric A in which the weft and warp yarns 2 and 3 are made of a synthetic resin that is strong in tensile strength so as to be able to withstand heavy objects, for example, flat yarns such as polyethylene or polypropylene as shown in FIG.
In the vicinity of both upper and lower ends of the screen, there are blind weave sections 4 and 5 consisting only of warp threads 2 with no weft threads 3, and H and h weave sections 5 at the lower end.
The main body is formed into a cylindrical shape by sewing a raw fabric in which a plurality of string passing holes 6 are bored at regular intervals in parallel to the main body, and the string passing holes 6 are formed as shown in FIG. This is a circular bag stitch 7.

Then, the closure rim 8 is inserted into the upper end of the blind weave 4 as shown in FIG.
is inserted through the bag bottom tightening string 10 through the string passing hole 6.

To make a bag like the one described above, first tie the bottom strap 9, push the tied part inward as shown in Fig. 4, and then tighten the bottom strap 1.
0 is squeezed to close the bottom of the bag, and after the contents are filled in this state, the closing edge 8 is squeezed and the bag is suspended and transported using a hanging band as described later.

When transported in the above manner, there is no risk of the bottom slipping off during hanging transportation as the bottom of the bag is squeezed in two stages.
It can be stably placed vertically on a freight car, etc.

When the main strap 10 at the bottom of the bag is loosened to release the contents, the weight of the contents forces the portion bound by the bottom strap 9 to fall.

By the way, there is a string passing hole 6 in the bag stitching section 7, and the bag bottom tightening string 10 is inserted through the hole, so the string passing hole 6 is not directly exposed on the inner surface of the main body. The contents will not leak, and the strength will not be weakened due to the provision of the large string hole 6.

In addition, the bag bottom is shaped by the bag-stitched perforations due to the filling pressure, and no unevenness occurs, so the outer shape can be changed stably.

In the above embodiment, the string passing hole 6 is provided in the 7 portions of the bag stitches, but the 7 portions of the bag stitches are configured to have a blind weave as shown in FIG. Even if it is inserted, the same effect is achieved.

The hanging pan 11 is stretched across the left and right openings of the light bag, and both sides are sewn vertically on the sides of the main body 1.

As shown in FIGS. 7 to 11, the sewing state is such that an overlapping part 13 is provided in which a part 12 of the bag is pinched and sewn from the left and right sides, and a suture thread 14 is provided below the overlapping part 13.
This is a so-called back muscle stitch.

When the hanging band 11 is put together in this way, the closing edge 8
Even if the bag opening is squeezed and a vertical wrinkle force is generated, the overlapping part 13 will not be stretched in the horizontal direction, and the downward force of the overlapping part 13 will cause a wide force to form. The stitching never comes off, and the overlapping portion 13 maintains the quadruple stitched structure of the band 11 and the part 12 of the bag 1 and performs the same function as adding reinforcing fabric.

Therefore, the burden on the lower end 17 of the sewing part 16, which originally tends to receive the load most intensively, is greatly reduced, and in addition, as the elongation rate is lowered from the overlapped part 13 to the lower end 17, Since the elongation rate gradually approaches that of the woven fabric portion of the bag 1, there is no risk of cracks occurring in the bag 1 around the lower end 17.

Furthermore, as shown in FIG. 5, the lower end 17 of the hanging band ends at a point that slightly faces the bottom surface when the contents are filled, so that the bottom part is not uneven and has a stable shape.

Furthermore, as a method of sewing the suspension band, there is also a method of sewing as shown in FIG. 12.

That is, only the D portion is sewn with a pinch back stitch as shown in FIGS. 7 to 11, and the other E portion is sewn with a simple plain stitch.

In this way, if only the D section is pinched and sewn along the spine, the contents will be filled into the H section, and the main body will be squeezed at the H section when it is lifted, so the pinched seam allowance will be in its natural state and can easily be sewn for reinforcing stitches. It fulfills its purpose and can also prevent the seam allowance from elongating, and since most of the work can be done by hand, the sewing work can be done with high efficiency.

Alternatively, as shown in FIG. 13, only the upper and lower ends may be pinched and sewn along the spine to form a Japanese band.

In the above embodiments, the single-layer bag is provided with seven bag stitches, and a string hole through which the main strap 10 of the bag bottom is inserted is provided, or a blind weave part is provided that is made only of warp yarns with no weft yarns. □
Although the description has been made for a multilayer bag, a similar structure can be applied to a multilayer bag.

That is, FIGS. 14 to 17 show this, and the outer bag 1 is constructed in the same manner as that of the embodiment described above.

Therefore, the same reference numerals in FIG. 14 refer to the same parts as in the embodiment described above.

However, reference numeral 18 indicates a temporary bag suspension belt provided at the pinch back seam portion of the suspension belt 11.

The inner bag shown in FIGS. 15 and 16 is placed inside the outer bag 1 as described above as shown in FIG. 17.

First, the bag constituting the second layer of the inner bag is made into a cylindrical shape by overlapping the ends of the polyfilm 19 as shown in FIG. or, as shown in the opening in FIG. 15, a polytube 21.

Further, the third layer inner bag 22 is made of resin cloth similar to the outer bag 1, as shown in FIG.

Thus, the second and third layers of the inner bag are successively superimposed on the outer bag, and the upper and lower ends of the inner bag 19 or 21 have string passing holes 23 through which the closing edge 8 or the waist tightening string 9 is inserted. .24 is provided, and string passing holes 26 and 26 are also provided at both upper and lower ends of the third layer inner bag 22.

In this way, by inserting the closing edge 8 or the waist tightening string 9 into the string passage hole or the blind tissue part of the inner and outer bags, the inner and outer bags are integrated.

□When such a bag is used as a large returnable bag, it has the following advantages.

In other words, commonly used returnable bags that are said to have interior properties are those that simply have a thick polyfilm inner bag wrapped around the main body of the bag, and in such bags, the adhesion between the main body and the inner bag is extremely poor. There is a disadvantage that it is difficult to fill the contents because the plastic film wrinkles and adheres to each other due to static electricity, and the inner bag may tear even if it is reused, so the inner bag must be replaced. There is a complexity to it.

However, when the above multilayer bag is used as a large return bag, it is moisture-proof and dust-proof, and the innermost layer of the bag sticks together and does not tear, so it can be reused. It has the advantage of being able to be manufactured at low cost because it can be processed in an assembly line by just preparing the original fabric, inner bag, belt, and required rope, and it is effective as a one-way bag that is treated to prevent foreign matter from entering. .

However, in this case, the effectiveness (1
Since leakage of contents is prevented by the inner bag, only the reinforcement of the outer bag has an advantage.

In any case, the present invention is to form a ring-shaped bag-like part on the inner and outer periphery of the lower door of the main body, and to form the bag-like part into a blind weave part consisting only of warp threads, with no weft threads, or Alternatively, a string pass-through hole is provided, and the bag bottom main tightening strings are inserted into this tissue part or the string pass-through hole at intervals of one leg so as to be hidden alternately, and are provided below the bag-shaped 8 parts. The bag bottom can be closed with the bag bottom tightening string after the bottom tightening string is inserted into the same blind tissue part or the string passing hole, and the part tied up with the bottom tightening string is pushed into the bag. , and a pair of left and right suspension bands are attached vertically to the sides of the main body to hang the heavy goods bag. Push it in, then squeeze the bag bottom tightening string to close the bag bottom and fill it with the contents,
A bag that can be transported by hanging it using a hanging band by squeezing the bag opening with the closing edge: Since the bottom is a two-stage squeezer, the bag bottom will not open easily and may be damaged. The bottom of the bag is standardized with □-sewn perforations depending on the filling pressure, and has the characteristic that it can be stably placed vertically on trucks, freight cars, etc., and the bottom of the bag has a main tightening string to release the contents. When the belt is untied, the weight of the contents pushes the part tied up with the straps so that they fall, so the contents can be easily released by untying the straps.

However, since the bag bottom main tightening string is not directly inserted into the main body but is inserted through the bag-shaped part, the contents will not leak when there is no inner bag, especially when the bag bottom main tightening string is inserted. The contents will not leak even if there is a shock when the bag is opened, the bottom of the bag will not be torn by the contents when the contents flow down, and the bag-like part will prevent the binding part of the bag from leaking. The vehicle was strengthened and most of the strings were hidden in the bag-shaped island, so the 6 bags of bag-shaped strings were also soiled and damaged.)
There is a characteristic.
