BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a flexible rectangular container which can be compacted by filling a container body with powder particles or the like and transporting the container body when not in use.

[0002]

2. Description of the Related Art In the conventional container of this kind, as shown in FIGS. 4 and 5, a container body 1'is formed in a rectangular plane shape by using a desired flexible sheet, and a long side of the container body 1'is formed. , The side walls 11 'and 12' of the short sides are attached to the outer surfaces of the side walls 11 ', 12' by attaching the suspension band 2 and the adjacent side walls 1 '
A diaphragm member 3'is laid between the inner surfaces of 1'and 12 ',
A hanging rope was passed between the hanging bands 2 and 2 which were adjacent to each other, and was carried by a crane or the like. As described above, the suspension belt 2 is provided at the center of the side walls 11 'and 12' in the width direction so that the balance of the container body 1'will not be lost when it is lifted by a crane or the like. The diaphragm member 3 ′ suppresses the bulging of the side walls 11 ′ and 12 ′ (shown by phantom lines in FIG. 4) due to the load of the powder / granular material filled in the container body 1 ′, and a large number of containers filled with the powder / granular material. This is for minimizing the dead space that occurs when the main bodies 1'are arranged side by side, and the ends 3a ', 3b' thereof are welded to the positions shown on the inner surfaces of the side walls 11 ', 12', whereby the side walls 11 '. , 12 'are equally divided (110', 120 ') to contribute to the reduction of the dead space.

[0003]

By the way, the reduction of the dead space mentioned above is achieved by the above-mentioned bulge being almost uniform regardless of the difference between the long side and the short side, in other words, the divided side wall portion. If the lengths of 110 'and 120' are almost the same, it becomes more effective. However, according to the conventional container described above, the base material 21 for fixing the suspension band 2 is welded to the center of the side wall 12 'in the width direction, and the base material 2 is fixed.
Since the end portion 3a 'is welded at a position deviating from 1, the length 120' becomes shorter than the divided side wall portion 110 '. Therefore, the bulges have different sizes on the long side and the short side, and as a result, the dead space cannot be further reduced. The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to enable the end portion of the partition member and the suspension band to be welded to the inside and outside of the widthwise center of the short side wall. Another object of the present invention is to provide a flexible rectangular container that can further reduce the dead space when arranging a large number of container bodies filled with powder particles.

[0004]

In order to achieve the above-mentioned object, the container of the present invention comprises a container body having a flat rectangular shape formed by using a flexible sheet, and a long side and a short side of the container body. In a flexible rectangular container formed by attaching a suspension band to the outer surface of the side wall and straddling a diaphragm member between the inner surfaces of adjacent side walls, the central portion of the short side wall of the container body has an inner-outer double structure, and The suspension band is welded to the outer surface and one end of the diaphragm member is welded to the inner surface.

[0005]

According to the above construction, the central portion of the short side wall has an inner-outer double structure, so that the suspension band and one end of the diaphragm member can be welded to the inner and outer surfaces of the side wall at the center in the width direction.
Therefore, the other end of the diaphragm member welded to the inner surface of the long side wall is
If the short side wall is welded to the end of the same side with a length that bisects the short side wall, the long side wall and the short side wall are equally divided into the same length.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the container of the present invention will be described below with reference to FIGS.
Will be described with reference to. In the figure, 1 is a container body, 2 is a suspension band, and 3 is a diaphragm member. The container main body 1 is formed of a flexible sheet such as a tarpaulin and is formed in a rectangular box shape in a plane using one and the other half peripheral wall portions 1a, 1a, a bottom wall portion 1b, and an upper wall portion (not shown).

The semi-peripheral wall portion 1a has a side wall 12a extending from one end of the long side wall 11 and the other side wall 12 at the other end.
Side wall side 12b bent inward from the middle part by the thickness of a
The side walls 12a and 12b facing each other and facing each other on the other half peripheral wall portion 1a are overlapped inside and outside, and the side walls 12a and 12b on both sides are welded to form the short side wall 12 At the same time, the side peripheral wall of the container body 1 is formed.

A bottom wall portion 1b is welded to the bottom surface of the side peripheral wall, and an upper wall portion is welded to the upper surface thereof, whereby the box-shaped container body 1 is formed. The upper wall portion is provided with a powder supply port and the bottom wall portion 1b is provided with a discharge port at appropriate positions (both not shown).

A suspension band 2 is attached to the center of the outer surface of each of the side walls 11 and 12 in the width direction. Further, the diaphragm member 3 is bridged between the inner surfaces of the side walls 11 and 12 adjacent to each other.

The suspension band 2 is welded to the outer side wall side 12a forming the short side wall 12 and the central portion of the base material 21 welded to the outer surface of each of the long side wall 11, and is the same as in the prior art. ,
It is provided as a convenience for transportation by a crane through a hanging rope.

The diaphragm member 3 is made of a sheet material in which a woven cloth is pressure-bonded to a synthetic resin sheet such as vinyl or EVA. One end 3a of the diaphragm member 3 is the center of the inner surface of the short side wall 12 in the width direction.
That is, the inner side wall 12b is pressure-bonded to the back side of the suspension band 2. In addition, the other end 3b is positioned on the inner surface of the long side wall 11 at a position shown in the drawing, that is, between the end of the side wall 11 and the short side wall 1.
