Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a flexible rectangular container, specifically a rectangular parallelepiped container, which can be filled with powder and granular materials for transportation, and can be folded and compacted when not needed.

(Prior art and its problems) Most of the conventional rectangular parallelepiped flexible square containers have a square planar shape as described in Utility Model Application No. 103441/1982; Although there was no square-shaped container, depending on container transportation circumstances, such as the shape of the pallet on which the container is placed, a rectangular parallelepiped with a rectangular planar shape may improve loading efficiency, so there is strong demand from users. Ta.

In addition, since flexible square containers are foldable and soft, their side walls tend to bulge due to the load of the powder and granules being filled and the load when loading the container, so preventing the side walls from bulging (deforming). In order to do this, a diaphragm member is spanned between the inner surfaces of adjacent side walls.In the conventional container described above, two diaphragm members are spanned in parallel at a predetermined interval to divide each side wall surface into the same number of parts (each The side wall surface was divided into five sections).

However, in the case of the above-mentioned conventional container with a square planar shape, since the container is spanned between side walls of the same shape, two membrane members are simply spanned in parallel with a desired spacing in the front and back, and each Even if the side wall surfaces are divided into the same number, there will be no difference in the bulge of each side wall, but if this configuration is used in a rectangular parallelepiped flexible square container with a rectangular planar shape, the short side side wall surface and the long side If the number of divisions between the side walls is the same, the lengths of the side walls spanned are different, so when the above load is applied, there will be a significant difference in bulge between the short side wall and the long side wall, causing the container to collapse. The rectangular planar shape of the container was greatly disrupted, and as a result, there was a strong possibility that the container would have poor loading efficiency.

(Problem to be solved by the invention) The present invention was devised in view of the above-mentioned problems of the prior art, and its purpose is to create a flexible angle whose planar shape is a rectangle and is new and useful. To provide a molded container, and to maintain the square shape of the container having a rectangular planar shape by minimizing the difference in bulge between the short side side wall and the long side side wall when filling the container with contents. .

(Means for Solving the Problems) The technical means of the present invention to achieve the above object is to provide a rectangular parallelepiped flexible container body having a rectangular planar shape, and a rectangular parallelepiped flexible container body having a rectangular planar shape. A diaphragm member is spanned between each adjacent inner surface of the short side side wall and the inner surface of the long side side wall on the side wall surface orthogonal to the upper surface, and the diaphragm member is a diaphragm member having a substantially V-shaped planar shape. Each membrane piece is provided with a through hole, and its V-shaped base end is fixed to the inner surface of the side wall on the short side of the container body, and the tips of both V-shaped membrane pieces are attached to the inner surface of the side wall on the long side. They are fixedly arranged at predetermined intervals.

(Function) By the technical means described above, the V-shaped proximal ends of adjacent diaphragm members are fixed to predetermined locations on the inner surface of the short-side side wall, dividing the short-side side wall into two or three parts, and the V-shaped The inward membrane pieces of the shaped membrane pieces are fixed to a desired location on the inner surface of the long side side wall, and the outward membrane pieces are fixed to the long side side wall to which the inward diaphragm member is fixed. It sticks between the fixed part and the corner part and further divides the space in between, and as a result, the long side side wall is divided into 4 to 5 parts, and the long side due to the load when filling the powder or the load when loading the container. The bulge on the side wall is subdivided into the bulge on the short side side wall.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the figure, A is a flexible rectangular container, and the container A consists of a container body a and a diaphragm member b. The top surface part A ₁ and the bottom surface part A ₂ are provided with a powder inlet A ₃ and a powder discharge port A ₄ respectively, and squeeze ropes A ₅ and A ₅ are attached respectively to the upper and lower ends. It can be opened/closed and folded freely, and the injection port a ₃
The structure of the discharge port _a4 is merely an example and is not limited to the illustrated example.

Note that a ₆ , a ₆ , a ₆ ′, and a ₆ ′ in the figure are slings that are vertically attached to the approximate center of the outer surface of the short side walls a ₇ , a ₇ and the long side walls a ₈ , a ₈ . A rope or the like is inserted through the container to facilitate transportation during loading and unloading using a crane or the like.

The diaphragm member b is made of, for example, a substantially rectangular synthetic resin sheet such as vinyl or EVA that is shorter than the longitudinal length of the side wall a ₇ or a ₈ of the container body a, and a synthetic resin sheet having the same shape as the synthetic resin sheet. It consists of two membrane pieces 1 and 1' made of a desired woven fabric which are sandwiched in a press-contact manner with the sheet at the front and back, and one edge of each is welded, glued, etc. It is fixed by the above means and formed into a substantially V-shaped planar shape.

In addition, the membrane pieces 1 and 1' have approximately elliptical through holes 2.
..., 2'... are respectively drilled.

Then, four of the V-shaped diaphragm members b...
A short side side wall a ₇ and a long side side wall a ₈ are adjacent to each other and are perpendicular to the top surface of the container body a which has a rectangular planar shape.
..., respectively, by fixing the V-shaped base end 3 to the inner surface between the corner a _{9 of the short-side side wall a 7 and} the sling a ₆ , so that the side wall a ₇ Divide into three approximately equally.

Then, the tip part 4 of the inward membrane piece 1 of the membrane pieces 1, 1' expanded in a V-shape is connected to the corner part _a9 of the long side side wall _a8 and the sling _a6 '. It is fixed to the inner surface between the film piece 1 and the fixed part of the tip 4 of the membrane piece 1 and the corner part.
a ₉ , fix the tip 4' of the other outer membrane piece 1' to further divide the space into two;
As a result, when each section is divided into five parts approximately equally and spanned so as to form an approximately V-shape in plan, a void portion 5 having an approximately triangular cross section in cross section is formed at each of the four internal corners a ₉ .
...is formed.

Therefore, the bulge of the long-side side wall _a8 due to the load during powder filling or the load during container loading is subdivided with respect to the bulge of the short-side side wall _a7 .

Note that the fixing means may be any desired means such as welding or adhesion, and the upper and lower ends b ₁ ,
A slight gap is provided between b ₂ and the inside of the top surface a ₁ and the inside of the bottom surface a ₂ of the container body a, respectively, to facilitate the injection and discharge of the powder and granular material.

By the way, in the illustrated example, the powder to be filled is 0.8 cm.
In the case of large-sized soybeans, the positions of the through holes 2 and 2' provided in the front and rear membrane pieces 1 and 1' of the diaphragm member b are set at an angle of repose so as to improve the discharge efficiency of the soybeans filled in the cavity 5. Although they are shifted up and down by x, the present invention is not limited to this.

Here, the angle of repose is the slope y when the center part of the packed powder is concavely concave when the discharge port _A4 is opened to discharge the powder. The angle x formed with the horizontal plane z is defined as the angle x formed behind the through hole 2 so that the soybeans in the cavity 5 are discharged through the through holes 2 and 2' on the slope forming the angle of repose x. The through hole 2' is positioned at the upper level.

For reference, an example of each angle of repose in various powders and granules is shown below: Powder Angle of repose Sand (dry) 12−30 mesh 32.5° 30−45 mesh 32.5° 45−85 mesh 35° (wet) Moisture content 1% 30-45 mesh 37.5° Water content 2% 30-45 mesh 41° Crushed stone 0.5-0.64 mesh 40.5° Sawdust 12-30 mesh 47.5° Soybean 0.8cm 28° Sesame 12-30 38.5°.

Note that the V-shape of the diaphragm member b is not limited to the expansion angle shown in the illustrated example, and although not shown, a single membrane piece is folded in half and the folded portions are overlapped to form a V-shape. The diaphragm member b may be provided with a letter-shaped base end portion 3.

(Effect of the invention) The present invention has the above-mentioned configuration, and the V-shaped base end portions of adjacent diaphragm members are fixed to predetermined locations on the inner surface of the short side side wall, so that the short side side wall is Divide into three parts, and fix the inward membrane piece of the V-shaped membrane pieces to a desired location on the inner surface of the long side wall, and fix the outward membrane piece to the above-mentioned inward membrane member. It sticks between the fixed part of the long side side wall and the corner part, further dividing the space into two, and as a result, the long side side wall is divided into four or five parts, and the load when filling the powder or container Since the bulge of the long side side wall due to the load during loading can be subdivided into smaller parts relative to the bulge of the short side side wall, the bulge of the long side side wall becomes smaller one by one, and the bulge of the short side side wall becomes smaller. As a result, the square shape of the flexible container, which has a rectangular planar shape, can be maintained.

Therefore, a flexible square container with a rectangular planar shape that has excellent loading efficiency can be provided, which is very useful and of great practical value.

In addition, since the V-shaped base end portions are overlapped and fixed to the inner surface of the side wall, the strength of the fixed portion is improved, and the short side side wall is provided with a strap provided on the outer surface for hanging the diaphragm member. Although the surface is narrow, since it is a single piece with a V-shaped base end, it is easy to set the attachment part to the hanging surface, and the side wall on the short side prevents bulging. It is enough.
