Abstract

PURPOSE:To keep self standing of the erecting part of a bag container at the time of loading/unloading while making good use of the merit of a flexible container by attaching a flexible airtight chamber in which a gas is pressure- injectable, on a bag body wall. CONSTITUTION:An airtight chamber 8 which is provided on the whole outer surface of an erecting part 1 is formed by the erecting part 1 of a flexible container and a flexible film 9 which is provided on the outside of the erecting part 1, and the erecting part 1 and the film 9 are connected by connecting parts 10 with an appropriate distance. At the end of a pressure gas pipe 11 by which a compressed gas is pressure-injected/discharged to the airtight cham ber 8, a connector 12 is provided, and it is connected to a compressed gas source such as compressor or bomb, etc. By this method, the erecting part 1 of a flexible container can be made to stand by itself, and the work efficiency at the time of loading/unloading is improved. Also, an internal residue of the bag container after unloading decreases.

[Industrial Application Field] The present invention relates to a flexible container (hereinafter referred to as flexible container) used in various fields as a simple transport container for granules.
Regarding the structure of [Prior art 1] In general, a flexible container is made of durable woven or non-woven fabric and has a cylindrical shape with an upper plate and a lower plate at the upper and lower ends, respectively.The upper plate has an inlet and the lower plate has an outlet. , the mouths of these can be closed with robes, etc. If the schematic structure is explained in Figure 3 showing the side, ■ is the upright part;
la is an upper plate, lb is a lower plate, and 2 is a reinforcing belt. An input port 3 is provided in the upper plate 1a at the upper end of the upright part l, and a lower plate 1 at the lower end.
A discharge port 4 is provided at b. Squeezing tables 5 and 6 or squeezing lobes are attached to the input port 3 and the discharge port 4, respectively, and when charging material, the discharge port 4 is completely closed with a squeezing tape 6 or a squeezing lobe in advance. If necessary, after charging, the input port 3 is closed with the throttle table 5 or throttle lobe, and discharge is performed by loosening the throttle table 6 or the throttle lobe and opening the discharge port 4. Furthermore, a hanging lobe 7 is provided at the upper part of the upright part 1 in the form of an extension of the reinforcing belt 2. [Problem to be solved by the invention] The advantage of flexible containers is their simplicity; in addition to being inexpensive and economical, they can be folded up when there is no charge, so the difference in volume contributes greatly to transportation costs. ing. On the other hand, a major drawback of conventional flexible containers is that they cannot maintain their upright parts independently when loading and unloading, so they have to rely on manual labor to maintain an independent posture that makes loading and unloading easy. there were. Especially when discharging fine powder,
Due to the low bulk specific gravity of the charge, it was difficult to completely discharge it, and the actual situation was that people had to push the flexible container directly from the outside for a long time. The present invention aims to provide a flexible container whose upright portion can be maintained independently during loading and unloading of charges while taking advantage of the advantages of the flexible container. [Thousand Steps to Solve the Problems J] The present invention provides a flexible container in which a flexible airtight chamber into which gas can be freely pressurized is attached to the wall of the bag, and the airtight chamber can be formed into a mesh body. [Function 1] The present invention will be explained with reference to the drawings. Figure 1 is a partial cross-sectional side view of the case where the airtight chamber is provided on the entire outer surface of the upright part, and 8 is the airtight chamber and the upright part l of the flexible container and its outside. The upright part l and the membrane body 9 are connected by a connecting part 10 at an appropriate distance. 11 is a pressure air pipe for pressurizing and releasing compressed gas into the airtight chamber, l2
is a connector provided at the end of the pneumatic pipe, and is connected to a compressed gas source such as a compressor or cylinder. To explain the operation of the present invention, when the flexible container is not in use, when the compressed gas is removed from the airtight chamber, the airtight chamber is flexible and can be folded like a conventional flexible container, and the volume is extremely small. When compressed gas is injected into the airtight chamber when charging the charge, the airtight chamber expands into an automorphic shape, and the flexible container becomes a self-supporting cylindrical shape, making the charging process extremely easy. Once loaded, the compressed gas is removed and the container can be transported in the same way as conventional flexible containers. Furthermore, when discharging, the compressed gas is again pressurized into the airtight chamber, and then the discharge port is opened, and the charge is smoothly discharged in the same manner as discharge from the fixed container. Since the inner surfaces of the upright parts do not come into close contact with each other during discharge, the amount of charge remaining is also very small. After the discharge is complete, the compressed gas is removed, the airtight chamber contracts, and the flexible container can be folded. The airtight room is not only the outside of the upright part, but also the inside or inside.
Alternatively, as shown in a partially sectional side view in FIG. It can be provided not only on the outer surface of the part, but also on the inner or inner/outer surface. In either case, the action and effect of pressurizing and releasing compressed gas into the airtight chamber are the same. Note that the airtight chamber may be further provided on the outer surface and/or inner surface of the input port and/or the discharge port, and the same effect as in the upright portion can be obtained. As described above, the present invention has been able to take advantage of the advantages of flexible containers while covering their disadvantages, so it not only expands the field of use of flexible containers to six different areas, but also greatly reduces the cost of transportation packaging by improving workability.

Example 1 Example 1 A flexible container of the type shown in FIG. 1 was manufactured. The upright part has a diameter of 1100 mm, a height of 1100 mm, and a radial length of the connecting part of about 5 mm. The upright part, the membrane body, and the connecting body are all made of a nylon nonwoven laminate sheet. By injecting compressed air into the airtight chamber using a compressor, the airtight chamber expands into its own shape and the upright part becomes independent, and by releasing the compressed air, the airtight chamber contracts, allowing the flexible container to be folded. . Example 2 In place of the airtight chamber in Example 1, a mesh body made of synthetic rubber and consisting of mutually communicating pipes with an outer diameter of 10 mm and an inner diameter of 9 mm was provided by covering the outer surface of the upright part, as shown in FIG. A flexible container of the type shown in was manufactured. By pressurizing and releasing compressed air into the mesh, the same effect as in Example 1 was obtained. [Effects of the Invention] Since the upright part of the flexible container can stand on its own, the workability during loading and unloading, which is a drawback of conventional flexible containers, is greatly improved, and the amount of charge material remaining inside after discharge is reduced. was completed.
