Description

Carrying bags and hanging carriers

[0001] The present invention relates to a carrying bag and a hanging carrier.

[0002] Flexible container bags are known as packaging materials suitable for packing and transporting powdery materials such as grains, feed, and soil and sand. A known flexible container bag has an opening at the top, into which contents are filled and then removed through a discharge port at the bottom. Patent Document 1 proposes providing a slope at the bottom of the bag to facilitate removal of the contents through the discharge port.

[0003] Japanese Patent Application Laid-Open No. 2009-035326

[0004] However, the flexible container bag described in Patent Document 1 has a discharge port on the side of the bag, making it difficult to smoothly remove the contents. It takes a long time to remove powder with low fluidity in particular. Therefore, an object of the present invention is to provide a transport bag that allows for smooth removal of the contents.

[0005] The present invention provides a transport bag for transporting contents, which has a filling opening for the contents and a discharging opening for the contents, and has a sloping area from the filling opening to the discharging opening when viewed from the side of the transport bag.

[0006] The present invention also provides a hanging carrier comprising the transport bag and a hanging member arranged on the outside of the transport bag, wherein the hanging member has a central portion and an extension portion extending outward from the central portion, and the extension portion has a hanging engagement portion at its tip region.

[0008] The present invention will now be described based on preferred embodiments with reference to the drawings. Figure 1 shows one embodiment of a transport bag of the present invention. The transport bag 10 shown in the figure is suitable for transporting solid contents filled therein. Examples of solid contents include, but are not limited to, powders and granular materials.

[0009] The transport bag 10 has a hollow body 11. The transport bag 10 also has a contents discharge port 12 located at the lower end of the body 11. The transport bag 10 also has a contents filling port 13 located at the upper end of the body 11. In the embodiment shown in Figure 1, the discharge port 12 is located at the lower end of the body 11, and the filling port 13 is located at the upper end of the body 11. A line connecting the center position of the filling port 13 in a cross section and the center position of the discharge port 12 in a cross section (hereinafter, this line will be referred to as the "vertical center line") is parallel to the vertical direction.

[0010] The body 11 includes a first body 11a located on the discharge port 12 side and a second body 11b located on the filling port 13 side. Both the first body 11a and the second body 11b are cylindrical. In the embodiment shown in FIG. 1 , both the first body 11a and the second body 11b are cylindrical. The diameter of the first body 11a is larger than the diameter of the second body 11b. The center of the circle in the cross section of the first body 11a coincides with the center of the circle in the cross section of the second body 11b. The upper end of the first body 11a and the lower end of the second body 11b are smoothly connected.

[0011] In a side view, the transport bag 10 has a sloped region 14 extending from the filling port 13 toward the discharge port 12. The sloped region 14 is provided in the lower end region of the first body portion 11a of the body 11. The sloped region 14 has a sloped surface extending from the filling port 13 toward the discharge port 12 on at least a portion of its inner surface. In this specification, the term "slope" refers to a surface extending from any position on the inner surface of the transport bag 10 toward the longitudinal centerline of the transport bag 10 when viewed from the filling port 13 toward the discharge port 12 in a plan view of the transport bag 10. In the embodiment shown in FIG. 1, the entire inner surface of the sloped region 14 is sloped. Specifically, in the cross section of the sloped region 14, the diameter of the circle on the inner surface gradually decreases from the filling port 13 toward the discharge port 12. Similarly, in the inclined region 14, the diameter of the outer circle in its cross section gradually decreases from the filling port 13 side toward the discharge port 12 side. As a result, the inclined region 14 has a funnel-like shape.

[0012] As described above, in the transport bag 10 of the embodiment shown in FIG. 1 , the body 11 has a non-inclined region 15 in the area other than the inclined region 14 in the lower end region of the first body portion 11a. The non-inclined region 15 is cylindrical. In the transport bag 10 of the embodiment shown in FIG. 1 , the upper portion of the first body portion 11a and the entire second body portion 11b are non-inclined regions 15. As a result, the inclined region 14 in the transport bag 10 is located in the area from the position between the discharge port 12 and the filling port 13 to the discharge port 12. Specifically, the inclined region 14 is located only in the area from the lower end region of the first body portion 11a to the discharge port 12.

[0013] 1, a screw thread is provided on the outer surface of the discharge portion 12a including the discharge outlet 12. A closing member (not shown) for closing the discharge outlet 12 and preventing the contents of the transport bag 10 from falling out is screwed onto this screw thread. Instead of screwing, a ferrule joint, for example, may be used as a means for attaching the closing member to the discharge outlet 12.

[0014] To fill the transport bag 10 shown in FIG. 1 with contents, the discharge port 12 is first blocked with the above-described blocking member (not shown). The contents are then filled into the transport bag 10 through the filling port 13. After filling with the contents, the filling port 13 is closed, and the transport bag 10 is transported to a predetermined discharge position. Once the transport bag 10 is transported to the discharge position, the blocking member (not shown) unblocks the discharge port 12, allowing the contents to be discharged from the transport bag 10 through the discharge port 12. Because the transport bag 10 is provided with the inclined region 14 as described above, the contents flow smoothly down the inclined surface of the inclined region 14, allowing the contents to be discharged smoothly and quickly. Therefore, even if the contents are, for example, powder with low fluidity, it is possible to avoid requiring a long time to remove the contents.

[0015] To facilitate smoother discharge of the contents of the transport bag 10, it is preferable that the inclination angle of the inclined region 14 be a specific value. The inclination angle is the angle θ between the horizontal plane H and the inclined surface 16, as shown in FIG. 2 . When the angle θ between the horizontal plane H and the inclined surface 16 is 90 degrees, the inclined surface 28 is parallel to the vertical plane and is not inclined. When the angle θ between the horizontal plane H and the inclined surface 16 is 0 degrees, the inclined surface 16 is parallel to the horizontal plane and is not inclined. Therefore, the inclination angle θ is greater than 0 degrees and less than 90 degrees. The inclination angle θ is preferably 2 degrees or greater, more preferably 10 degrees or greater, and even more preferably 20 degrees or greater. The inclination angle θ is preferably 88 degrees or less, more preferably 80 degrees or less, and even more preferably 70 degrees or less.

[0016] To facilitate the smooth discharge of the contents of transport bag 10, inclined region 14 is preferably made of a material hard enough to be self-supporting. In this specification, "self-supporting" means that a 50 mm x 50 mm square sample taken from inclined region 14 can maintain a vertically aligned state. By making inclined region 14 self-supporting, deformation of the inclined surface of inclined region 14 is less likely to occur when the contents are removed, which allows the contents to flow down more smoothly along the inclined surface of inclined region 14.

[0017] If the inclined region 14 is self-supporting, the non-inclined region 15 may or may not be self-supporting. From the viewpoint of improving the handleability of the transport bag 10, for example, from the viewpoint of easy storage by folding when not in use, it is preferable that the non-inclined region 15 is not self-supporting. For example, the transport bag 10 may be configured to include a hollow body 11, a contents discharge opening 12 located at the lower end of the body 11, and a contents filling opening 13 located at the upper end of the body 11, and the body 11 may be configured to include a flexible region (i.e., a region that is not self-supporting) located on the filling opening 13 side and a rigid region (a region that is self-supporting) located between the flexible region and the discharge opening 12, and the rigid region may have an inclined surface on at least a portion of its inner surface that faces the discharge opening 12.

[0018] When the inclined region 14 and / or the non-inclined region 15 are self-supporting, these regions are preferably made of, for example, hard rubber, thermoplastic resin, thermosetting resin, or metal.

[0019] On the other hand, if the inclined region 14 and / or the non-inclined region 15 are not self-supporting, these regions are preferably made of a flexible material. Examples of such materials include woven or knitted fabrics made of synthetic or natural fibers, nonwoven fabrics made of synthetic fibers, films made of thermoplastic resins, laminated sheets of these, or composite sheets such as aluminum laminate sheets made by laminating these with a metal vapor deposition film such as an aluminum vapor deposition film, or aluminum foil.

[0020] Regardless of whether the inclined region 14 is self-supporting, the inclined region 14 and the non-inclined region 15 may be integrally formed or may be separate. The inclined region 14 and the non-inclined region 15 being integrally formed means that there is no seam between the inclined region 14 and the non-inclined region 15. The inclined region 14 and the non-inclined region 15 being separate means that the inclined region 14 and the non-inclined region 15 are joined by some means, such as adhesive, welding, fitting, or sewing. If the inclined region 14 is self-supporting and the non-inclined region 15 is not self-supporting, it is preferable that the two be separate from each other in terms of ease of manufacturing the transport bag 10.

[0021] Figures 3(a) to 3(c) show another embodiment of the transport bag 10 shown in Figure 1. Note that, for points not specifically explained in relation to the embodiment shown in Figures 3(a) to 3(c), the explanations for the embodiment shown in Figure 1 apply as appropriate.

[0022] The transport bag 10 shown in Figure 3(a) has a sloped region in the approximate center region of the transport bag 10, instead of the sloped region in the lower end region of the transport bag 10. Specifically, the transport bag 10 has a cylindrical first non-sloped region 15a that includes the filling port 13, and a cylindrical second non-sloped region 15b that includes the discharge port 12. The diameter of the cross section of the first non-sloped region 15a is larger than the diameter of the cross section of the second non-sloped region 15b. The transport bag 10 also has a sloped region 14 between the first non-sloped region 15a and the second non-sloped region 15b.

[0023] The transport bag 10 shown in FIG. 3( b) is configured with an inclined region throughout the entire length of the transport bag 10, rather than providing a non-inclined region. Specifically, the transport bag 10 is configured with an inclined region 14 extending from the inlet 13 to the outlet 12. While the inclination angle of the inclined region 14 is the same at every position in the inclined region 14 in this figure, a combination of multiple inclined regions with different inclination angles may be used instead. For example, the inclined region 14 may be configured with three inclined regions with different inclination angles, specifically, a first inclined region located closest to the inlet 13, a third inclined region located closest to the outlet 12, and a second inclined region located between the two inclined regions, with the inclination angles decreasing in the order of the first inclined region, the second inclined region, and the third inclined region. Alternatively, the inclination angles may increase in the order of the first inclined region, the second inclined region, and the third inclined region.

[0024] The transport bag 10 shown in FIG. 3( c) has multiple inclined regions and multiple non-inclined regions. Specifically, the transport bag 10 has a first non-inclined region 15a including the filling port 13. The first non-inclined region 14a is located directly below the first non-inclined region 15a. The second non-inclined region 15b is located directly below the first non-inclined region 14a. The second non-inclined region 14b including the discharge port 12 is located directly below the second non-inclined region 15b. Both the first non-inclined region 15a and the second non-inclined region 15b are cylindrical. The cross-sectional diameter of the first non-inclined region 15a is larger than the cross-sectional diameter of the second non-inclined region 15b. The inclination angles of the first inclined region 14a and the second inclined region 14b increase in this order. Alternatively, the inclination angles may decrease in the opposite order. Alternatively, the inclination angles of the first inclined region 14a and the second inclined region 14b may be the same.

[0025] In any of the above-described embodiments of the transport bag 10, the volume of the transport bag 10 can be appropriately changed depending on the contents. For example, the volume of the transport bag 10 may be 1 liter or more, 10 liters or more, or 100 liters. On the other hand, the volume of the transport bag 10 may be 10,000 liters or less, 5,000 liters or less, or 1,000 liters or less.

[0026] FIG. 4 shows another embodiment of the transport bag of the present invention. The transport bag 20 shown in this figure includes a cylindrical inner bag 21. The configuration of the inner bag 21 can be similar to that of the transport bag 10 of the embodiment shown in FIG. 1 described above. A filling port 23 can be located at the upper end of the inner bag 21. A discharge port 22 can be located at the lower end of the inner bag 21. Specifically, the inner bag 21 includes a hollow body 21A. The inner bag 21 also includes a discharge port 22 located at the lower end of the body 21A. The inner bag 21 also includes a filling port 23 located at the upper end of the body 21A. In the embodiment shown in FIG. 4, the discharge port 22 is located at the lower end of the body 21A, and the filling port 23 is located at the upper end of the body 21A.

[0027] The body 21A includes a first body 21a located on the discharge port 22 side and a second body 21b located on the filling port 23 side. The first body 21a and the second body 21b are both tubular, for example, cylindrical. The diameter of the first body 21a is larger than the diameter of the second body 21b. The upper end of the first body 21a and the lower end of the second body 21b are smoothly connected.

[0028] The inner bag 21 has a sloped region 24 in a side view. The sloped region 24 is provided in the lower end region of the first body portion 21a of the body portion 21A. The sloped region 24 has a sloped surface that slopes from the filling port 23 side toward the discharge port 22 side on at least a portion of its inner surface. In the embodiment shown in FIG. 4 , the entire inner surface of the sloped region 24 is shown as a sloped surface. Specifically, in the sloped region 24, the diameter of the inner circle in its cross section gradually decreases from the filling port 23 side toward the discharge port 22 side. Similarly, in the sloped region 24, the diameter of the outer circle in its cross section gradually decreases from the filling port 23 side toward the discharge port 22 side. As a result, the sloped region 24 has a funnel-like shape.

[0029] In addition, for the points not specifically described regarding the configuration of the inner bag 21, the explanation regarding the embodiment of the transport bag 10 shown in Figure 1 described above applies as appropriate.

[0030] 4, the transport bag 20 of this embodiment further includes a guide member 26 that covers the outer surface of the lower end region of the inner bag 21. The guide member 26 is attached to the inner bag 21 so as to cover the outer surface of the inclined region 24 located in the lower end region of the inner bag 21. The guide member 26 may cover only the outer surface of the inclined region 24 of the inner bag 21, or it may cover not only the outer surface of the inclined region 24 but also the outer surface of the inner bag 21 other than the inclined region 24.

[0031] The guide member 26 has an opening 27 in its central region when viewed from above. The shape of the opening 27 is not particularly limited as long as it allows the contents to be discharged. For example, it can be a circle, a rectangle, or any other polygonal shape. If the opening 27 is circular, its diameter is larger than the diameter of the discharge portion 22a, including the discharge port 22, of the inner bag 21. Therefore, for example, the discharge portion 22a can be passed through the opening 27 of the guide member 26, and the guide member 26 can be disposed in the inclined region 24 of the inner bag 21. Alternatively, as shown in FIG. 5, the guide member 26 can be a circular ring with a fan-shaped cutout. In this case, one of the two radially extending cutout ends is a locking portion 26a, and the other is a locked portion 26b. By locking the locking portion 26a to the locked portion 26b, the funnel-shaped guide member 26 shown in FIG. 4 can be formed. In this case, the guide member 26 can be easily attached and detached by simply wrapping the guide member 26 in the state shown in Figure 5 (i.e., the unlocked state) around the discharge section 22a of the transport bag 20 and then locking the locking section 26a with the locked section 26b. In either of the above-mentioned forms of the guide member 26, it is preferable that the guide member 26 is detachable from the inner bag 21, as this improves the handleability of the transport bag 20. However, the guide member 26 may not be detachable from the inner bag 21.

[0032] The guide member 26 has an inner surface that is complementary in shape to the outer surface of the inclined region 24 of the inner bag 21. The guide member 26 also has an inclined surface 28 that faces the discharge outlet 22 on at least a portion of its inner surface. Figure 4 shows a state in which the entire inner surface of the guide member 26 is inclined surface 28 that faces the discharge outlet 22. As a result, the guide member 26 shown in the figure has a funnel-like shape.

[0033] To fill the transport bag 20 shown in Figure 4 with contents, first, the discharge portion 22a is passed through the opening 27 of the guide member 26, and the guide member 26 is positioned in the inclined region 24 of the inner bag 21. This completes the transport bag 20. In this state, the discharge portion 22a protrudes downward from the guide member 26. Next, the discharge opening 22 is closed with a closing member (not shown). In this state, the inner bag 21 is filled with contents through the filling opening 23. After filling with contents, the filling opening 23 is closed, and the transport bag 20 is transported to a predetermined discharge position in this state. When the transport bag 20 is transported to the discharge position, the closing member (not shown) releases the discharge opening 22, allowing the contents filled in the inner bag 21 to be discharged to the outside of the inner bag 21 through the discharge opening 22. As described above, the inner bag 21 of the transport bag 20 is provided with the inclined region 24, and the guide member 26 is attached to the portion corresponding to the inclined region 24, so that the contents are guided along the inclined surface of the inclined region 24 and flow smoothly downward. As a result, the contents can be discharged more smoothly and quickly than in the embodiment shown in Fig. 1. Therefore, even if the contents are, for example, powder with low fluidity, it is further avoided that it takes a long time to remove the contents.

[0034] From the viewpoint of even smoother removal of the contents from inner bag 21, guide member 26 is preferably made of a rigid body. In this specification, the guide member being a rigid body means that when guide member 26 is placed on a horizontal table with its opening 27 facing downward (i.e., the state shown in FIG. 4 ), it has enough rigidity to maintain the inclination of inclined surface 28 of guide member 26. To impart rigidity to guide member 26 and make it a rigid body, guide member 26 may be made of, for example, thick hard rubber, thermoplastic resin or thermosetting resin, or metal.

[0035] In this embodiment, the inner surface of the guide member 26 is provided with an inclined surface, which improves the ease of removal of the contents packed in the inner bag 21. Therefore, unlike the embodiment of the transport bag 10 shown in Figure 1 described above, it is not essential that the inclined region 24 of the inner bag 21 be self-supporting. However, it is not prohibited for the inclined region 24 to be self-supporting.

[0036] From the viewpoint of even smoother removal of the contents from the inner bag 21, it is preferable that the angle of inclination of the inclined surface on the inner surface of the guide member 26 approximately matches the angle of inclination of the outer surface of the inclined region 24 of the inner bag 21. This results in the outer surface of the inclined region 24 of the inner bag 21 and the inner surface of the guide member 26 having approximately complementary shapes, making it easier to stably maintain the inclined state of the inclined region 24 of the inner bag 21. In this specification, "approximately matches" means that the difference between the angle of inclination of the inclined surface on the inner surface of the guide member 26 and the angle of inclination of the outer surface of the inclined region 24 of the inner bag 21 is within ±10 degrees. Note that in this specification, the angle of inclination of the inner bag 21 refers to the angle measured when the inner bag 21 is placed on a flat surface without any contents inside.

[0037] Figure 6 shows a modified example of the embodiment shown in Figure 4. The transport bag 20' shown in Figure 6 is formed by covering the outside of the transport bag 20 shown in Figure 4 with an outer bag 25 made of a water- and air-impermeable material. The outer bag 25 has a generally cylindrical shape with open top and bottom. The outer bag 25 entirely covers the inner bag 21 to which the guide member 26 is attached. The lower end region of the outer bag 25 is airtightly fixed by a fastener 29 at the position of the discharge portion 22a located at the lower end of the inner bag 21. Although not shown, the upper end region of the outer bag 25 is airtightly sealed at a position above the upper end of the inner bag 21.

[0038] In this way, by covering the entire inner bag 21 with the guide member 26 attached by the outer bag 25, even if the inner bag 21 filled with contents is damaged, the contents that have spilled out of the inner bag 21 due to the damage are prevented from leaking further by the outer bag 25. As a result, contamination of the working environment by the contents is prevented. Furthermore, by airtightly covering the inner bag 21 with the outer bag 25, the contents that have spilled out of the inner bag 21 due to the damage can be prevented from coming into contact with the atmosphere, which also prevents the deterioration and degradation of the contents and the diffusion of compounds such as gases that are generated as a result.

[0039] From the above viewpoints, examples of materials for the outer bag 25 include films containing polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, or polyamides such as polyamide 6 and polyamide 66, or laminated films made of any combination of these resins. Composite films such as these films and metal vapor deposition films such as aluminum vapor deposition films, or aluminum laminate sheets made by laminating these films with aluminum foil can also be used.

[0040] Next, we will explain the contents to be filled into the transport bag of the present invention. While there are no particular limitations on the type of contents to be filled into the transport bag, the inclined region of the transport bag of the present invention allows for smooth and quick removal of even low-fluidity contents. In other words, the transport bag of the present invention is particularly suitable for filling with low-fluidity contents. From this perspective, the transport bag of the present invention is suitable for use in containing powders with a Carr fluidity index of 0 to 59, particularly 0 to 50. The Carr fluidity index is an evaluation index that comprehensively and quantitatively expresses the fluidity of a powder. It is an index that represents the fluidity of a powder calculated based on four parameters: the angle of repose, compressibility, spatula angle, and uniformity or cohesion of the powder. An index of 0 to 25 is assigned based on the measured values ​​of each parameter, and the sum of the four parameters is the Carr fluidity index, expressed as an index of 0 to 100. The closer the value is to 100, the better the fluidity of the powder.

[0041] In particular, sulfide compounds can be used as the contents to be filled into the transport bag of the present invention. Many sulfide compounds have low fluidity. In particular, the smaller the particle size of sulfide compounds, the lower their fluidity becomes. When these compounds are filled into conventional flexible containers and transported, they often cannot be discharged smoothly, which can be time-consuming. In addition, some sulfide compounds react with moisture in the air to generate gas, and if transporting such sulfide compounds requires a long time, there is a high risk of reaction with the air.

[0042] A typical example of the sulfide compound is a sulfide solid electrolyte. Various types of sulfide solid electrolytes are known. A typical sulfide solid electrolyte is Li ２ S-P ２ S ５ , Li ２ S-P ２ S ５ -LiX (where "X" represents one or more halogen elements), Li ２ S-P ２ S ５ -P ２ O ５ , Li ２ S-Li ３ P.O. ４ -P ２ S ５ , Li ３ P.S. ４ , Li ４ P ２ S ６ , Li １０ GeP ２ S １２ , Li ３．２５ Ge ０．２５ P ０．７５ S ４ , Li ７ P ３ S １１ , Li ３．２５ P ０．９５ S ４ , Li ａ P.S. ｂ X ｃ(where "X" represents one or more halogen elements, a represents a number of 3.0 or more and 9.0 or less, b represents a number of 3.5 or more and 6.0 or less, and c represents a number of 0.1 or more and 3.0 or less.) Other examples include the sulfide solid electrolytes described in WO 2013 / 099834 and WO 2015 / 001818, and sulfide solid electrolytes containing a crystalline phase having an argyrodite-type crystal structure.

[0043] When a sulfide compound is used as the content, the water vapor permeability of the transport bag 10 shown in FIG. 1 and the inner bag 21 shown in FIG. 4 is set to 2.0 g / (m ２ 24h) or less, and ２ 24h) or less, and 0 g / (m ２ The water vapor permeability is measured in accordance with JIS K7129.

[0044] Next, a method for transporting the tote bag described above will be described. A hanging member is used to transport the tote bag. The hanging member is placed on the outside of the tote bag and used together with the tote bag. The combination of the tote bag and the hanging member is referred to as a hanging carrier in this specification. Figure 7 shows a hanging member used in the present invention. The hanging member 30 shown in this figure has a central portion 32 with an opening 31 corresponding to the discharge outlet of the tote bag. Note that the tote bag 20 shown in this figure is similar to the tote bag 20 shown in Figure 4. The hanging member 30 also has multiple arms 33 extending radially from the central portion 32. Figure 7 shows the hanging member 30 with four arms 33 extending radially from the central portion 32. Each arm 33 has a base portion 33a extending from the central portion 32 and having a wide, band-like shape with a constant width. The arm portion 33 is connected to the tip of the base portion 33a and gradually decreases in width toward the tip. However, the arm portion 33 may have a constant width over its entire length.

[0045] It is preferable that the arms 33 are arranged so that the angles between any two adjacent arms 33 are equal when the hanging member 30 is viewed in plan, as this facilitates balancing the distribution of mass when a carrying bag is hung by the hanging member 30. Figure 7 shows a state in which the angles between any two adjacent arms 33 are all 90 degrees.

[0046] A fastening string 34 is attached to each arm 33. When the transport bag 20 is wrapped and suspended by the suspension member 30, the fastening strings 34 are used to fasten the fastening strings 34 attached to adjacent arm portions 33 together (see FIG. 9 ) to stabilize the suspended state of the transport bag 20. For this purpose, the fastening strings 34 are attached to the arm portions 33 so as to extend in a direction intersecting the extension direction of the arm portions 33 and extending outward from each side edge of the arm portions 33. FIG. 7 shows the state in which the fastening strings 34 extend outward from each side edge of the arm portions 33 perpendicular to the extension direction of the arm portions 33. The fastening strings 34 are attached to the arm portions 33 near the boundary between the base portion 33a and the tip region 33b. The tip region 33b is connected to the base portion 33a and is a region whose width gradually decreases toward the tip.

[0047] Each arm 33 has a hanging engagement portion at its tip region. Figure 7 shows a state in which a loop member 35 is attached as the hanging engagement portion. The loop member 35 is used for hanging the transport bag 20 from a hook (not shown) provided on the transport equipment when the transport bag 20 is wrapped and hung by the hanging member 30. For this purpose, the loop member 35 is attached to the tip region 33b so that the circumferential direction of the loop coincides with the extension direction of the arm 33.

[0048] The method for transporting the carrying bag 20 using the hanging member 30 having the above-described configuration is as follows. First, as shown in FIG. 7 , the hanging member 30 is placed horizontally and each arm 33 is unfolded. In this state, the discharge portion 22a located at the lower end of the carrying bag 20 is passed through the opening 31 formed in the center portion 32 of the hanging member 30. This causes the discharge portion 22a to protrude below the hanging member 30. In this state, the inner bag 21 of the carrying bag 20 is empty. A closing member 36 is attached to the discharge portion 22a protruding below the hanging member 30. The closing member 36 may be, for example, a butterfly valve or a sealing valve equipped with an opening / closing lever 37. After the closing member 36 is attached to the discharge portion 22a, it is confirmed that the closing member 36 is closed, and then the inner bag 21 is filled with contents through the filling opening 23 of the inner bag 21. The content is preferably filled to the extent that it fills the space corresponding to the first body portion 21a in the inner bag 21. Depending on the type of content, the content may be filled into the inner bag 21 in the air or in an inert atmosphere such as nitrogen gas or argon gas.

[0049] 8, the second body 21b of the inner bag 21 (which is empty) is rolled up from the filling port 13 toward the first body 21a, and the rolled-up state is maintained by a fixing means (not shown), making the inside of the inner bag 21 airtight. This completes the preparation for hanging the transport bag 20 by the hanging member 30.

[0050] Next, as shown in Figure 9, the transport bag 20 is suspended by the suspension member 30. The suspension is performed by suspending the loop member 35 of the suspension member 30 from a hook 41 attached to a suspension jig 40 provided on the transport equipment. This completes the suspension carrier 50 consisting of the transport bag 20 and the suspension member 30. The suspension jig 40 is made of a high-strength material and has a cross shape, with a hook 41 attached to each end of the cross. The suspension jig 40 is movable along a running rail (not shown) provided on the transport equipment.

[0051] When the carrying bag 20 is suspended by the hanging members 30, the fastening strings 34 attached to adjacent arms 33 are fastened together to stabilize the suspended state of the carrying bag 20. In this state, the carrying bag 20 can be seen between the adjacent arms 33 of the hanging members 30. In other words, in the hanging carrier 50, the carrying bag 20 is suspended by the hanging members 30 so that the carrying bag 20 can be seen between the adjacent arms 33. This is advantageous in that the state of the carrying bag 20 can be visually confirmed while it is suspended and while the contents are being removed.

[0052] Once the hanging carrier 50 is completed as described above, the hanging jig 40 is moved to transport the hanging carrier 50 to a predetermined discharge position. To facilitate transportation, a loop (not shown) can be provided on the outer surface of one of the arms 33. There are no particular limitations on the location of the loop, but for example, the loop can be provided on the outer surface of the longitudinal center region of the arm 33. The hanging carrier 50 can be easily moved by engaging a moving hook with the loop and using a traction source (not shown) such as a winch to pull the hanging carrier 50 via the moving hook. Once the hanging carrier 50 has been transported to the discharge position, the discharge port of the closing member 36 is released, allowing the contents of the carrying bag 20 to be discharged to the outside of the carrying bag 20 through the discharge port. At this time, the state of the carrying bag 20, specifically, the state of the contents being discharged from the carrying bag 20 and the volume of the carrying bag 20 decreasing, can be easily observed through the gap formed between the two adjacent arms 33 of the hanging member 30.

[0053] While the present invention has been described above based on preferred embodiments, it is not limited to these embodiments. For example, in the transport bag 10 shown in FIG. 1 and the transport bag 20 shown in FIG. 4, the non-inclined region is composed of two parts, the first body section and the second body section. However, as shown in FIG. 10, the non-inclined region may instead be composed of only the first body section 11a. Furthermore, while the hanging member 30 shown in FIG. 7 has four arms 33, the number of arms 33 is not limited to this and may be, for example, three or fewer or five or more. Furthermore, the hanging carrier 50 shown in FIG. 9 relates to a combination of the transport bag 20 shown in FIG. 4 and the hanging member 30 shown in FIG. 7. Alternatively, the hanging carrier 50 may be formed by combining the transport bag 10 shown in FIG. 1 and the hanging member 30 shown in FIG. 7.

[0054] While the hanging member 30 shown in FIG. 7 is cross-shaped and includes a central portion 32 and multiple arms 33, a hanging member shaped like a flexible container bag may be used instead. In this case, the hanging member has a central portion and extensions extending outward from the central portion. The extensions may be provided with a hanging engagement portion at their distal end. However, it is advantageous for the extensions to be made of arms 33 shown in FIG. 7, as this allows for easy visual confirmation of the state of the carrying bag during hanging and removal of its contents. Furthermore, while the guide member 26 shown in FIG. 4 is funnel-shaped, a guide member shaped like an upside-down truncated pyramid, such as a truncated triangular pyramid or a truncated square pyramid, may be used instead.
