Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a flexible rectangular container which can be compacted by folding the container body when it is not used, while transporting the container body filled with powder or the like.

[0002]

[Prior Art]

 Conventionally, in this type of container, as shown in FIGS. 4 and 5, the container body 1'is formed into a flat rectangular shape by using a desired flexible sheet, and the long side and the short side of the container body 1'are formed. The base material 21 is welded to the outer surfaces of the respective side walls 11 ', 12' to attach the suspension band 2, and the diaphragm member 3'is laid between the inner surfaces of the adjacent side walls 11 ', 12'. The crane was used to carry a hanging rope between the belts 2 and 2. The suspension band 2 is provided in the center of the side walls 11 ', 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 as described above. 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 packed in the container body 1 ′, and a large number of containers filled with the powder / granular material. The purpose is to minimize the dead space that occurs when the main bodies 1'are arranged side by side, and their ends 3a ', 3b' 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]

[Problems to be solved by the device]

 By the way, the above-mentioned reduction of the dead space is achieved if the above-mentioned bulge is substantially uniform regardless of the difference between the long side and the short side, in other words, the length of the divided side wall portions 110 ′, 120 ′ is reduced. If they are almost the same, it will be 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 end portion 3a' is welded to the position away from the base material 21. Therefore, the length 120 'is 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 ends 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]

[Means for Solving the Problems]

 In order to achieve the above object, the container of the present invention forms a flat rectangular container body using a flexible sheet, and attaches a suspension band to the outer surfaces of the long side and short side walls of the container body. In addition, in a flexible rectangular container formed by bridging a diaphragm member between the inner surfaces of adjacent side walls, the central part of the side wall on the short side of the container body has an inner-outer double structure, and the hanging band is formed on the outer surface of the container. In addition, one end of each of the diaphragm members is welded.

[0005]

[Action]

 According to the above configuration, since the central portion of the short side wall has the inner-outer double structure, 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, if the other end of the diaphragm member, which is welded to the inner surface of the long side wall, is welded to the end of the same side by a length that bisects the short side wall, the long side and the short side are welded. The side wall is divided into almost equal lengths.

【Example】

 An embodiment of the container of the present invention will be described below with reference to FIGS. In the figure, 1 is a container body, 2 is a suspension band, and 3 is a diaphragm member. The container body 1 is made of a flexible sheet such as a tarpaulin, and is formed into a rectangular box shape having a rectangular shape using one and the other half peripheral walls 1a, 1a, a bottom wall 1b, and an upper wall (not shown). .

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

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 sides 12a forming the short side wall 12 and the central portion of the base material 21 welded to the outer surfaces of the long side wall 11, respectively. , For convenience of transportation by crane etc. through the hanging rope.

The diaphragm member 3 is made of, for example, a sheet material in which a woven cloth is pressure-bonded to a synthetic resin sheet such as vinyl, EVA, etc., and one end 3 a thereof is located at the center in the width direction on the inner surface of the short side wall 12, that is, the inner side wall 12 b. It is crimped to the back side of the suspension belt 2 in. Further, the other end 3b is located at the position shown in the inner surface of the long side wall 11, that is, the short side wall 12 is bisected between the other end 3b and the end of the side wall 11. The side wall portions 110 and 120 are welded to each other at the same length.

According to the container of the present embodiment having the above-described configuration, by welding the one end 3a and the other end 3b of the diaphragm member 3, the side walls 11 and 12 on the long side and the short side have substantially the same length. It is divided into equal parts. Therefore, the swelling of the side wall portions 110 and 120 when the container body 1 is filled with the granular material becomes substantially uniform over the entire side wall of the container body 1 as shown by the phantom line in FIG. It is possible to further reduce the dead space when a large number of container bodies 1 filled with bodies are arranged side by side.

In the present embodiment, the semi-peripheral wall portion 1a is formed such that one side wall side 12a is on the outside and the other side wall side 12b is on the inside. However, the present invention is not limited to this, and for example, both side wall sides may be formed. If the central part of the short side wall 12 has a double-sided inner / outer structure, such as using one half-peripheral wall part whose outer side is on the outside and the other half-peripheral wall part whose both side walls are on the inside. is there.

Further, in the present embodiment, the adjacent diaphragm members 3, 3 are integrally formed by connecting the adjacent ends 3a, 3a in series, and the diaphragm member 3 which has been conventionally used is two. Although the present invention is effective, the present invention is not limited to this, and the one ends 3a, 3a may be divided, and the adjacent diaphragm members 3, 3 may be formed separately.
