An outer bag made of resin cloth having a discharge port at the bottom of the foldable tubular body and a hanging portion at the outer peripheral wall, and is relatively large on both side edges of the bottomed tubular body of the same size as the outer bag. A flexible container with a double structure in which an inner bag made of tough paper is used to form a pleated tubular shape with a deep fold.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flexible container having a double structure in which about 1 ton of rice, cement, and feed is stored and transported.

[0002]

[Prior Art]

 Conventionally, as a container for accommodating about 1 ton of storage, which is widely used, a synthetic resin sheet or a resin cloth is widely used as a material for the purpose of the bag in order to have sufficient strength.

[0003]

[Problems to be solved by the device]

 However, in a conventional container made of this kind of resin cloth or the like, a separate inlet, outlet, etc. are installed, and the upper and lower ports are sealed by them, which requires a lot of time and effort for the installation work. In addition, since a resin cloth made of synthetic resin is used as a material in order to have sufficient strength for lifting cargo to move the contents after they are poured, it is extremely difficult to dispose of after use, and it is generally widely used such as incineration. There were various deficiencies in its handling work and disposal method, such as the fact that it had to be disposed of as used industrial waste products. The present invention relates to a completely new technique developed in view of these problems in the past.

[0004]

[Means for solving the problem]

 The present invention was devised in order to eliminate the above-mentioned deficiencies.The inner bag is a one-way system made of strong paper such as kraft paper, and the outer bag has a discharge port on the bottom and a hanging part on the outer peripheral wall. A running type inner and outer bag made of the resin cloth provided was combined to have a structure capable of withstanding a weight of about 1 ton. After using this container, only the inner bag combined inside should be separated from the outer bag and disposed of, and the flexible container with a double structure that can avoid the complexity of disposal after use. Pertain to.

EXAMPLES Now, an example of the implementation will be described in detail with reference to the drawings. For example, a stretched tape obtained by cutting a film of polyethylene, polypropylene or the like into a certain width is woven as warp or weft, or a resin cloth laminated on one side of the resin cloth, for example, a length of 1150 m. The bottom of the foldable tubular rest 2 with the folds 1 and 1 formed by making a tubular body with dimensions of m × body width 900 mm × bottom width 900 mm and pushing both ends deeply into the tubular body is a rectangular shape. A bottom 3 having a body width of 900 mm and a bottom width of 900 mm is provided in accordance with a conventional method such as attaching a resin cloth, pasting glue, and sewing with a sewing machine. A discharge port 4 having a size of about 250 mm is provided at the center of the bottom portion 3. The shape of this outlet is generally square, and it is desirable to reinforce the four circumferences to prevent deformation of the shape of the outlet. Further, a hanging tool having a horizontal belt 5 and a hanging belt 6 laid in a square shape is attached to the outer peripheral wall of the tubular body to form an outer bag. Further, for example, two layers of tough paper such as extensible kraft paper 84 g / m ² base paper are used, and with the same dimensions as the tubular body, both side ends are deeply pushed into the tubular body and pleated with folds 7, 7. The lower end of the tubular body 8 is provided with a bottom portion 9 according to a conventional method such as pasting glue, sewing with a sewing machine, and the like to form an inner bag. The inner bag is combined with the inner bag to form a flexible container having a double structure according to the present invention.

[0006]

[Effect of the device]

 Since the inner bag is combined inside the outer bag in the present invention, after filling the contents from the upper mouth, the upper mouth can be folded inward and easily sealed by adhesive tape or glue. In order to transport or move this, since the hanging part attached to the outer peripheral wall of the outer bag is configured to be lifted by a crane or the like, it can be moved in a stable state. After that, to remove the contents, open the part of the inner bag corresponding to the outlet formed on the bottom of the outer bag with a knife, or use a triangular knife under the suspended container. It may be arranged, and the container itself may be lowered to open the bag. Therefore, since the container of the present invention has the depth of the folds located at the center of the bag, it becomes a square prismatic body having a substantially square shape after storing the contents, and the packing is neat and stable. Therefore, the container of the present invention has a double structure in which the inner bag is a one-way system and the outer bag is a running system, and after taking out the contents, the inner bag can be easily separated from the outer bag and discarded. On the other hand, since the outer bag can be used multiple times, it can be used as a new container by replacing and inserting a new inner bag inside. The container of the present invention has a double structure with a one-way inner bag and a running outer bag for the purpose of playing a role in industrial waste treatment. Since the amount of waste as a waste product is limited to the paper in the inner bag and the frequency of waste treatment in the outer bag can be minimized, it is possible to provide a container of great practical value that can contribute to economic reduction. is there.
