[Modes for carrying out the invention]

[0009] Hereinafter, embodiments of the present invention will be described with reference to the figures.

[0010] Figure 1 is a schematic perspective view of a flexible container transport member according to a first embodiment of the present invention. As shown in Figure 1, the flexible container transport member 1 comprises a lifting belt 11, a lifting rope 12, an upper belt 13, a support member 14, a first hook-and-loop fastener 15, a lower belt 16, and a bottom 17.

[0011] The suspension belt 11 is a belt that extends vertically, and as shown in Figure 1, one end (upper end) is connected to the end of the suspension rope 12, and the other end is connected to the bottom 17. The length of the suspension belt 11 is preferably 80 to 150 cm. The width of the suspension belt 11 is preferably 5 to 15 cm. Examples of materials for the suspension belt 11 include polypropylene.

[0012] The suspension rope 12 is connected at both ends to one end of each of the two suspension belts 11. The suspension rope 12 is used to suspend the flexible container when lifting it. As shown in Figure 1, there are two pairs of suspension ropes 12, which are connected to a total of four suspension belts 11. The material of the suspension rope 12 can be, for example, polypropylene.

[0013] The upper belt 13 is a ring-shaped belt that is connected to the suspension belt 11 at its upper part, approximately perpendicular to the suspension belt 11. The material of the upper belt 13 is not particularly limited, but examples include polypropylene. The connection position between the suspension belt 11 and the upper belt 13 is preferably a position where the suspension belt 11 protrudes 15 to 40 cm upward.

[0014] The support member 14 is a member provided on the inside (bag side) of the belts at the connection point between the suspension belt 11 and the upper belt 13. The support member 14 is fixed to the suspension belt 11 and / or the upper belt 13 on its outer surface, and is positioned so that its left-right center and the left-right center of the suspension belt substantially overlap. A first hook-and-loop fastener 15 is provided on the surface opposite to the fixing surface (inner surface). The support member 14 may also connect the suspension belt 11 and the upper belt 13, or it may reinforce the above connection point.

[0015] The first hook-and-loop fastener 15 is fixed to the support member 14 and adheres to the hook-and-loop fastener provided on the side of the bag. The method of fixing the first hook-and-loop fastener 15 to the support member 14 is not particularly limited as long as they are not separated during work, but for example, sewing is one option. The first hook-and-loop fastener 15 may be a male hook-and-loop fastener or a female hook-and-loop fastener. Examples of male hook-and-loop fasteners include hook tape and mushroom tape. Examples of female hook-and-loop fasteners include loop tape and napping tape. The vertical width of the first hook-and-loop fastener 15 is preferably 20 to 40 cm, and the horizontal width is preferably 10 to 30 cm. Furthermore, it is preferable that the upper end of the first hook-and-loop fastener protrudes 8 cm or more above the upper edge of the upper belt.

[0016] The lower belt 16 is a ring-shaped belt that is connected to the suspension belt 11 at its lower part, approximately perpendicular to the suspension belt 11. The material of the lower belt 16 is not particularly limited, but for example, polypropylene, similar to the suspension belt 11, can be used. The connection position between the suspension belt 11 and the lower belt 16 is preferably such that the suspension belt 11 protrudes 5 to 30 cm downwards.

[0017] The bottom portion 17 is connected to the other ends of the four suspension belts 11 and is intended to support all or part of the bottom of the bag. As shown in Figure 1, the bottom portion 17 may be provided with a discharge member 18, or, from the viewpoint of further stabilization, may be equipped with support ropes, auxiliary fabric, hook-and-loop fasteners, etc.

[0018] FIG. 2 is a schematic perspective view of an example of a flexible container including a member for transporting a flexible container according to the first embodiment of the present invention. As shown in FIG. 2, the flexible container 2 includes a member 1 for transporting a flexible container and a bag body 21.

[0019] The bag body 21 is a bag for accommodating the contents to be transported. As shown in FIG. 2, the bag body 21 includes a second surface fastener 22 and an opening 23. The bag body 21 may further be provided with a discharge portion for discharging the contents on the bottom surface.

[0020] The second surface fastener 22 is provided on the upper part of the side surface of the bag body 21 and is adhered to the first surface fastener 15. The second surface fastener 22 may be a male surface fastener or a female surface fastener, but in order to be adhered, it must be a surface fastener of a different type from the first surface fastener 15. Examples of the male surface fastener include hook tape and mushroom tape. Examples of the female surface fastener include loop tape and napping tape. The vertical width of the second surface fastener 22 is preferably 20 to 40 cm, and the horizontal width is preferably 10 to 30 cm. The size relationship between the first surface fastener 15 and the second surface fastener 22 is not particularly limited, but from the viewpoint of performing work stably, when the sizes are different, it is preferable that the smaller surface fastener is entirely adhered to the larger surface fastener.

[0021] The opening 23 is provided at the upper end of the bag body 21, and the contents are accommodated in the bag body 21 through the opening 23. After accommodation, it is tied with a tape, rope, or the like to close the opening 23.

[0022] FIG. 3 is a schematic perspective view showing an example of a conventional flexible container. As shown in FIG. 3, the conventional flexible container 3 includes a suspension member 31, a bag body 32, an opening 33, a patch 34, a bottom 35, and a discharge portion 36. The suspension member 31 is fixed to the bag body 32. Therefore, crushing becomes a large burden when disposing of it. In addition, the bag body 32 may be damaged when the patch 34 or the like peels off during work.

[0023] FIG. 4 is a schematic cross-sectional view around a surface fastener in an example of a flexible container provided with a member for transporting a flexible container according to a first embodiment of the present invention. As shown in FIG. 4, in this example, from the outermost side, an upper belt 13, a suspension belt 11, a support member 14, a first surface fastener 15, a second surface fastener 22, and a bag body 21 are arranged in this order.

[0024] In FIG. 4, the first surface fastener 15 is a hook tape and the second surface fastener 22 is a loop tape, but it is not limited thereto. The bag body 21 is supported at the upper part by the first surface fastener 15 and the second surface fastener 22 to be adhered, and the upper belt 13.

[0025] (Test on the tensile shear strength of the surface fastener) As a pair of male and female surface fasteners, two types of surface fasteners A with a male surface fastener being a hook tape and surface fasteners B with a male surface fastener being a mushroom tape were prepared. With the female surface fastener being a loop tape, first, a test on the tensile shear strength was conducted on the above surface fasteners according to the test on the tensile shear strength defined in JIS L 3416.

[0026] [Table 1]

[0027] [Table 2]

[0028] As shown in Tables 1 and 2, hook-and-loop fastener B had a higher tensile shear strength. However, for the flexible container according to the embodiment of the present invention, hook-and-loop fastener A was found to be preferable considering the ease of attachment and detachment during work. The tensile shear strength of hook-and-loop fastener A is preferably 10 to 20 N / cm². 2 That is the case.

[0029] (Performance testing of flexible containers) A flexible container equipped with a flexible container transport member according to the first embodiment of the present invention was tested using hook-and-loop fastener A, in accordance with the repeated top lifting test, compression and stacking test, and drop impact test specified in JIS Z 1651, to confirm that it meets the performance requirements. The tested flexible container has the following characteristics. Fineness: PP1500D Belt type: PP100mm Rope type: PP14mm Bag dimensions: 1100Φ × 1100H (mm) Maximum filling amount: 1000kg Volume: 1000 liters Substitute materials used in the test: resin pellets, iron balls, and gravel.

[0030] [Repeated top lifting test] Based on cross-standard test conditions, a lifting test was conducted with a load of 6000 kg (= 1000 kg (maximum filling capacity) × 6 (safety factor)). Additionally, a repeated top lifting test was performed for 70 cycles with a load of 4000 kg (= 1000 kg (maximum filling capacity) × 4). As a result, no problems were found in the post-test condition of the flexible container equipped with the flexible container transport member according to the embodiment of the present invention.

[0031] [Compression and stacking tests] The containers were stacked in three layers and subjected to a load of 5,400 kg, which is 5.4 times the maximum filling capacity of 1,000 kg, for 6 hours. As a result, there were no problems with the condition of the flexible container equipped with the flexible container transport member according to the embodiment of the present invention after the test.

[0032] [Drop Impact Test] The flexible container was dropped from a height of 0.8m onto a hard, flat horizontal surface. As a result, there were no problems with the condition of the flexible container equipped with the flexible container transport member according to the embodiment of the present invention after the test.

[0033] Performance tests of the flexible container described above revealed that a flexible container equipped with a flexible container transport component according to the embodiment of the present invention can be used in the same way as a conventional flexible container. Furthermore, when using hook-and-loop fastener A, although slight misalignment occurred at the adhesive surface during the test, it did not completely peel off, indicating that no problems occurred within the range of normal filling amounts.

[0034] In conventional flexible containers, when lifted, the lifting members are pulled vertically upward, and accordingly, the bag body to which the lifting members are fixed becomes longer vertically than when it is placed. As a result, a large load is placed on the fixing part between the lifting members and the backing cloth and the bag body, and in some cases, it may break. In contrast, in the flexible container according to the embodiment of the present invention, although the hook-and-loop fasteners are bonded to each other, the lifting belt is not fixed to the bag body. Therefore, when lifted, when the lifting belt is pulled vertically upward, the bag body sinks downward relative to the flexible container transport member. When it sinks downward, the hook-and-loop fasteners smooth the movement of the bag body, and the upper belt supports the bag body which tries to bulge outwards as it sinks. As a result, it is possible to work safely and stably without placing a large load on the flexible container. In addition, by providing a lower belt, the bag body is supported from below and lateral swaying during work can also be suppressed.

[0035] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
