Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cargo transportation, and in particular provides a liquid bag for transporting bulk fluid. Background Art
[0002] As a sturdy and standardized loading tool, containers can be used to transport fluid goods. In the current logistics field, the use of containers to transport fluids has become a widely adopted new large-scale transportation mode. The core lies in the combination of containers and soft liquid bags designed specifically for fluids. This container fluid bag can effectively replace traditional packaging forms such as tank containers and iron drums with higher costs; it is suitable for multiple transportation routes such as sea, rail and road.
[0003] Although container fluid bags have demonstrated high efficiency in the transportation of large fluid cargoes, the fluidity of the fluid also brings challenges: during transportation, the fluid tends to sway inside the container, which may not only cause damage to the liquid bag, but also cause serious safety accidents, such as the transport vehicle overturning, resulting in casualties.
[0004] To avoid this situation, the existing technology often uses ropes, brackets, etc. to firmly fix the liquid bag in the container to prevent it from shaking or shifting during transportation. However, the fixing effect is limited, and the liquid bag may still be damaged due to shaking during transportation. Moreover, this method has a poor effect on suppressing the shaking of fluid cargoes, and it is difficult to ensure transportation and installation. During long-term transportation or encountering severe bumps, the ropes or brackets may become loose or damaged.
[0005] In summary, the existing liquid bags have poor effect in suppressing shaking during transportation and are easily damaged by shaking.
[0006] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention
[0007] The present invention aims to solve the above technical problem, that is, to solve the problem that the existing liquid bags have poor effect in suppressing shaking during transportation and are easily damaged due to shaking.
[0008] The present invention provides a liquid bag for transporting bulk fluid, the liquid bag comprising a bag body, a fluid storage space formed in the bag body, a fluid inlet and a fluid outlet connected to the fluid storage space being arranged on the bag body; a partition is arranged in the fluid storage space, the partition being configured to block the flow of fluid in the fluid storage space.
[0009] In the preferred technical solution of the above-mentioned fluid bag, there are multiple partition members, and the multiple partition members divide the fluid storage space into multiple fluid compartments, and the multiple fluid compartments are directly or indirectly connected.
[0010] In a preferred technical solution of the above-mentioned liquid bag, each of the partition members forms a gap with the inner bottom wall of the bag body, and the plurality of fluid compartments are directly or indirectly connected through the gap.
[0011] In the preferred technical solution of the above-mentioned liquid bag, each of the partition members forms a gap with the inner side wall of the bag body, and the plurality of fluid compartments are directly or indirectly connected through the gap.
[0012] In the preferred technical solution of the above-mentioned liquid bag, each of the partition members forms a gap with the inner top wall of the bag body, and the plurality of fluid compartments are directly or indirectly connected through the gap.
[0013] In the preferred technical solution of the above liquid bag, each of the partitions forms a gap with at least one of the inner bottom wall, the inner side wall and the inner top wall of the bag body, and the multiple fluid bins are directly or indirectly connected through the gap.
[0014] In the preferred technical solution of the above-mentioned fluid bag, each of the partition members is provided with a notch, and the plurality of fluid compartments are sequentially connected through the notch.
[0015] In the preferred technical solution of the above-mentioned liquid bag, the lateral projections of the multiple notches overlap; or, the lateral projections of the multiple notches are arranged up and down; or, the lateral projections of the multiple notches are arranged left and right; or, the line segment connecting the center points of the lateral projections of the multiple notches is an inclined line segment; or, the lateral projections of the multiple notches are distributed in an array.
[0016] In the preferred technical solution of the above-mentioned liquid bag, the bag body is formed by splicing a plurality of bag pieces, and the liquid bag also includes an outer bag, which wraps and covers the bag body; and / or the bag body and / or the partition piece are made of PE, PP, PVC or TPU; and / or a flexible ring is provided on one of the partition piece and the inner wall of the bag body, and an inflatable part inserted into the flexible ring is provided on the other of the partition piece and the inner wall of the bag body, and the partition piece is connected to the inner wall of the bag body when the inflatable part is inflated.
[0017] In the preferred technical solution of the above-mentioned liquid bag, an inflatable part is provided on the partition piece, and a flexible ring is provided on the inner wall of the bag body, and the inflatable part is inserted into the flexible ring. When the inflatable part is inflated, the partition piece is connected to the inner wall of the bag body; preferably, an inflation valve port is provided in the area of the partition piece away from the inner wall of the bag body, and the internal space of the partition piece is connected with the internal space of the inflation part, so that the inflation part can be inflated after inflation through the inflation valve port.
[0018] In the case of adopting the above technical solution, the liquid bag for transporting bulk fluid of the present invention comprises a bag body, a fluid storage space is formed in the bag body, a partition is arranged in the fluid storage space, and the partition is arranged to block the flow of fluid in the fluid storage space. The present invention divides a large volume of bulk fluid into multiple small volumes by arranging a partition in the fluid storage space, effectively preventing the large volume of bulk fluid from shaking as a whole in a large extent. Compared with the external fixing method (rope or bracket), the partition arranged inside can better adapt to various transportation conditions, including severe bumps and long-term transportation, and significantly improves the effect of suppressing fluid shaking.
[0019] Furthermore, the present invention also forms a gap between the partition piece and the inner bottom wall of the bag body, so that multiple fluid bins are directly or indirectly connected at the bottom of the liquid bag. At the same time, since the fluid discharge port of the container is located at the bottom, the fluid outlet is connected to the fluid discharge port and the fluid can be released and discharged from the bottom of the liquid bag. By forming a gap between the partition piece and the inner bottom wall of the bag body, no matter how much fluid is in the liquid bag, it can effectively prevent shaking and facilitate the discharge of the fluid without changing the structure of the container.
[0020] Furthermore, the bag body of the present invention is formed by splicing a plurality of bag pieces, and an outer bag is used to wrap and cover the bag body, thereby effectively preventing the bag body from being worn and leaking during transportation; this design not only increases the overall sealing of the liquid bag, but the outer bag also provides an extra layer of protection for the inner bag, which can enhance the overall strength of the bag body, which is particularly important for liquid bags that need to withstand higher pressure or weight.
[0021] Furthermore, the present invention can ensure the shape of the liquid bag and prop up the bag body by setting the partition to be inflatable. When the internal fluid is less, the deformation and movement of the bag body can be reduced to a certain extent, thereby reducing the risk of the bag body being scratched or damaged.
[0022] Furthermore, the present invention can prevent the inflation valve opening from shaking or shifting and scratching the bag body by arranging the inflation valve opening in a region of the partition member away from the inner wall of the bag body. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.
[0036] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "front", "rear", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", "fourth", "fifth", and "sixth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0038] See first Figure 1 and Figure 2 ,like Figure 1 and Figure 2 As shown, the liquid bag for transporting bulk fluid of the present invention comprises a bag body 1, a fluid storage space 11 is formed in the bag body 1, a fluid inlet 12 and a fluid outlet 13 connected to the fluid storage space 11 are arranged on the bag body 1; a partition 2 is arranged in the fluid storage space 11, and the partition 2 is configured to block the flow of fluid in the fluid storage space 11.
[0039] Based on the above structural setting, a partition 2 is set in the fluid storage space 11 to divide a large volume of bulk fluid into multiple small volumes, effectively preventing the large volume of bulk fluid from shaking significantly as a whole and avoiding damage to the liquid bag. Compared with the external fixing method (rope or bracket) set internally, the partition 2 can better adapt to various transportation conditions, including severe bumps and long-term transportation, and significantly improves the effect of suppressing fluid shaking.
[0040] Preferably, there are multiple partitions 2, and the multiple partitions 2 divide the fluid storage space 11 into multiple fluid compartments, and the multiple fluid compartments are directly or indirectly connected, that is, the fluids in the multiple fluid compartments can flow. Figure 1 and 2As shown, there are 5 partition pieces 2, which are, from left to right, the first partition piece 21, the second partition piece 22, the third partition piece 23, the fourth partition piece 24 and the fifth partition piece 25. The 5 partition pieces 2 divide the fluid storage space 11 into 6 fluid compartments, which are, from left to right, the first fluid compartment 111, the second fluid compartment 112, the third fluid compartment 113, the fourth fluid compartment 114, the fifth fluid compartment 115 and the sixth fluid compartment 116, and the fluids in the six fluid compartments can circulate with each other. Of course, this is only a preferred setting method and is not restrictive. The number of partition pieces 2 can also be other numbers, such as 3, 4 or other values, and personnel in this field can set it according to actual conditions.
[0041] See next Figure 2 and 3 ,like Figure 2 and 3 As shown, each partition 2 forms a gap with the inner bottom wall of the bag body 1, and multiple fluid bins are directly or indirectly connected through the gap. Specifically, the lower surface of each partition 2 is spaced from the inner bottom surface of the bag body 1 to form a first gap 3, and each partition 2 has a first gap 3 below, that is, a gap is formed between the partition 2 and the inner bottom wall of the bag body 1, which enables multiple fluid bins to be directly or indirectly connected at the bottom of the liquid bag, and the bottom of each fluid bin can achieve mutual flow of fluids. At the same time, since the fluid outlet of the container is located at the bottom, the fluid outlet 13 is connected to the fluid outlet and the fluid can be released and discharged from the bottom of the liquid bag; by forming a gap between the partition 2 and the inner bottom wall of the bag body 1, no matter how much fluid is in the liquid bag, it can effectively prevent shaking and facilitate the discharge of the fluid without changing the structure of the container.
[0042] Furthermore, each partition 2 forms a gap with the inner top wall of the bag body 1, and multiple fluid compartments are directly or indirectly connected through the gap. Specifically, the upper surface of each partition 2 is spaced from the inner top surface of the bag body 1 to form a second gap 4, and there is a second gap 4 above each partition 2. When the fluid bag is loaded with fluid, it is generally not fully filled, so there is no need to connect the partition 2 to the top of the bag body 1, which can save materials, reduce the connection between the partition 2 and the top of the bag body, and reduce the connection process.
[0043] like Figure 3As shown, the front side of the partition piece 2 is connected to the front inner wall of the bag body 1, and the rear side of the partition piece 2 is connected to the rear inner wall of the bag body 1. When fluid is stored inside the bag body 1, the front side of the bag body 1 will be close to the front inner wall of the container (not shown in the figure), and the rear inner wall of the bag body 1 will be close to the rear inner wall of the container. At this time, the distance between the front inner wall and the rear inner wall of the bag body 1 reaches the preset maximum distance, and the partition piece 2 will also be stretched to become a partition piece that can block the flow of fluid, which can effectively prevent the fluid from shaking.
[0044] It should be noted that, although in the present preferred embodiment, the partition piece 2 forms a gap with the inner bottom wall and the inner top wall of the bag body 1, this is not restrictive. In other embodiments, each partition piece 2 only forms a gap with the inner side wall of the bag body 1, and multiple fluid bins are directly or indirectly connected through the gap; in other embodiments, each partition piece 2 only forms a gap with the inner bottom wall of the bag body 1, and multiple fluid bins are directly or indirectly connected through the gap; in other embodiments, each partition piece 2 forms a gap with both the inner side wall and the inner side wall of the bag body 1. A gap is formed, and a gap is formed with the inner bottom wall of the bag body 1, and multiple fluid compartments are directly or indirectly connected through the gap; in other embodiments, each partition piece 2 forms a gap with at least one of the inner bottom wall, the inner side wall and the inner top wall of the bag body 1, and multiple fluid compartments are directly or indirectly connected through the gap; it can be that the gaps formed by the multiple partition pieces 2 and the inner wall of the bag body 1 are located on the same side of the partition piece 2, or the gaps formed by the multiple partition pieces 2 and the inner wall of the bag body 1 are located on different sides of the partition piece 2. For example, the first method: as Figure 1 In the orientation shown, the first partition piece 21 forms a gap only with the front side wall, the second partition piece 22 forms a gap only with the rear inner wall, the third partition piece 23 forms a gap only with the upper inner wall, the fourth partition piece 24 forms a gap only with the lower inner wall, and the fifth partition piece 25 forms a gap only with the lower inner wall; The second way: the first partition piece 21 forms a gap only with the lower wall, the second partition piece 22 forms a gap only with the upper inner wall, the third partition piece 23 forms a gap only with the front inner wall, the fourth partition piece 24 forms a gap only with the rear inner wall, and the fifth partition piece 25 forms a gap only with the lower inner wall; Those skilled in the art can set it by themselves according to actual conditions, and the changes in the gap positions do not deviate from the basic principles of the present invention and shall fall within the protection scope of the present invention.
[0045] See also Figure 1In the orientation shown, the detailed explanation of the inner side wall of the bag body 1 of the present invention is as follows: if a plurality of partition members 2 are arranged in parallel left and right (the partition member 2 can prevent the fluid from swaying left and right), then the inner side wall refers to the front inner wall and the rear inner wall of the bag body 1, and the bag body 1 forms a gap with the inner side wall, which means forming a gap only with the front inner wall, and may also refer to forming a gap only with the rear inner wall, or may also refer to forming a gap with both the front inner wall and the rear inner wall; if a plurality of partition members 2 are arranged in parallel front and back (the partition member 2 can prevent the fluid from swaying back and forth), then the inner side wall refers to the left inner wall and the right inner wall of the bag body 1, and the bag body 1 forms a gap with the inner side wall, which means forming a gap only with the left inner wall, and may also refer to forming a gap only with the right inner wall, or may also refer to forming a gap with both the left inner wall and the right inner wall.
[0046] Further, see Figure 1 In the orientation shown, when a gap is formed between the partition piece 2 and the inner side wall of the bag body 1, for example, the partition piece 2 only forms a gap with the front inner wall of the bag body 1, the upper and lower rear three sides of the partition piece 2 can be connected to the upper and lower rear three side inner walls of the bag body 1 respectively. At this time, there is no obstruction from the bottom to the top of the front space of the bag body 1, which is convenient for the flow of fluid; similarly, if the partition piece 2 only forms a gap with the rear inner wall of the bag body 1, the upper and lower front three sides of the partition piece 2 can be connected to the upper and lower front three side inner walls of the bag body 1 respectively. At this time, there is no obstruction from the bottom to the top of the rear space of the bag body 1, which is convenient for the flow of liquid.
[0047] See next Figure 4 In another preferred embodiment of the liquid bag, a first gap 3 is formed between the partition piece 2 and the lower inner wall of the bag body 1, a second gap 4 is formed between the partition piece 2 and the upper inner wall of the bag body 1, a third gap 6 is formed between the partition piece 2 and the rear inner wall of the bag body 1, and a fourth gap 7 is formed between the partition piece 2 and the upper inner wall of the bag body 1. The front side of the partition piece 2 is connected to the front inner wall of the bag body 1 through a plurality of connectors 8, and the rear side of the partition piece 2 is connected to the rear inner wall of the bag body 1 through a plurality of connectors 8. Of course, this is not restrictive. In other embodiments, the upper part of the partition piece 2 can be connected to the upper inner wall of the bag body through a plurality of connectors 8, and the lower part of the partition piece 2 can be connected to the lower inner wall of the bag body through a plurality of connectors 8; the partition piece 2 is connected to the inner walls on both sides of the bag body 1 opposite to each other through the arrangement of the connectors 8, and gaps are formed around the partition piece 2 to facilitate the flow of the fluid. When the fluid is injected, it can be evenly distributed to each fluid bin, and the discharge of the fluid is convenient at the same time.
[0048] The connecting member 8 is preferably made of the same material as the partition member 2, and may also be a flexible connecting rope, or other structures, which can be set by those skilled in the art according to actual conditions.
[0049] In other embodiments, each partition member 2 is provided with a notch, and the plurality of fluid compartments are sequentially connected through the plurality of notches. Figure 5 , Figure 5 for Figure 1 Horizontal projection from left to right ( Figure 1 The partition piece 2 in the figure does not show the notch structure), the first partition piece 21 is provided with a first notch, which corresponds to Figure 5 The first notch projection 211 in the second partition piece 22 is provided with a second notch, which corresponds to Figure 5 The second notch projection 221 in the third partition sheet 23 is provided with a third notch, which corresponds to Figure 5 The third notch projection 231 in the fourth partition sheet 24 is provided with a fourth notch, which corresponds to Figure 5 The fourth notch projection 241 in the fifth partition sheet 25 is provided with a fifth notch, which corresponds to Figure 5 In the fifth notch projection 251 , the first notch projection 211 , the second notch projection 221 , the third notch projection 231 , the fourth notch projection 241 and the fifth notch projection 251 are arranged up and down.
[0050] In other embodiments, Figure 6 As shown, the first notch projection 211, the second notch projection 221, the third notch projection 231, the fourth notch projection 241 and the fifth notch projection 251 are arranged front to back. Figure 6 The multiple notches in the projection are set to be the front and back settings and the left and right settings in the paper direction.
[0051] In another embodiment, if Figure 7 As shown, the line segment connecting the center points of the first notch projection 211 , the second notch projection 221 , the third notch projection 231 , the fourth notch projection 241 and the fifth notch projection 251 is an inclined line segment, that is, the plurality of notches are arranged in sequence to be inclined downward.
[0052] It should be noted that the present invention does not impose any restrictions on the number and distribution of the notches. The lateral projections of multiple notches may overlap, or the lateral projections of multiple notches may be distributed in an array, or multiple notches may be provided on each partition member 2. Those skilled in the art may set them according to actual conditions.
[0053] See next Figure 8 ,like Figure 8As shown, the partition piece 2 is provided with an inflatable portion 202, and the inner wall of the bag body 1 is provided with a flexible ring 101. The inflatable portion 202 is inserted into the flexible ring 101. When the inflatable portion 202 is inflated, the partition piece 2 is connected to the inner wall of the bag body 1. Based on the above structural setting, the partition piece 2 is conveniently connected to the bag body 1. When the inflatable portion 202 is not inflated, it is in a contracted state and can be deeply inserted into the flexible ring 101. After the inflatable portion 202 is inflated, it is in a bloated state and can be firmly connected with the flexible ring 101.
[0054] Furthermore, the inflatable part 202 also includes a first limiting part 2021 and a second limiting part 2022. When the fluid impacts the partition 2 from right to left, the first limiting part 2021 and the second limiting part 2022 can prevent the inflatable part 202 from escaping from the flexible ring 101, thereby improving the connection strength between the inflatable part 202 and the flexible ring 101.
[0055] It should be noted that the present invention does not impose any limitation on the specific structure of the inflatable portion 202, which may be as follows: Figure 8 The "T"-shaped structure shown in the figure may also be an "L"-shaped structure, that is, only one first limiting portion 2021 or only one second limiting portion 2022 is provided, or the first limiting portion 2021 and the second limiting portion 2022 may form a disc-shaped structure, and those skilled in the art may set it according to actual conditions.
[0056] In addition, it should be noted that the present invention does not impose any restrictions on the specific connection method between the partition piece 2 and the inner wall of the bag body 1. One of the partition piece 2 and the inner wall of the bag body 1 may be provided with a flexible ring 101, and the other of the partition piece 2 and the inner wall of the bag body 1 may be provided with an inflatable part 202 inserted into the flexible ring 101, and the partition piece 2 and the inner wall of the bag body 1 are connected to the inner wall of the bag body 1 when the inflatable part 202 is inflated; or the partition piece 2 may be directly connected to the inner wall of the bag body 1 by gluing, sewing, heat sealing, ultrasonic welding or high-frequency welding.
[0057] Preferably, a first inflation cavity 201 is formed in the partition 2, a second inflation cavity 2023 is formed in the inflation portion 202, the first inflation cavity 201 is connected to the second inflation cavity 2023, and the partition 2 is set to an inflatable mode. After the partition 2 is inflated, it can give a certain support force to the inside of the liquid bag, so that the liquid bag maintains a straight shape. This is very important for the storage and transportation of the liquid bag, because it can ensure that the liquid bag maintains a stable shape during loading and unloading, and prevent fluid leakage or operational difficulties caused by shape changes. As the fluid in the liquid bag gradually decreases, the bag body 1 may be deformed due to the loss of fluid support. If the deformation is too large, it will not only affect the aesthetics of the liquid bag, but also increase the risk of the bag body 1 being scratched or damaged. The inflation of the partition 2 can reduce the deformation of the bag body 1 to a certain extent, so that the bag body 1 maintains a relatively stable shape; during transportation, the liquid bag may move due to bumps or vibrations. This movement may not only cause fluid leakage, but also cause additional wear to the liquid bag. Inflation of the partition 2 can reduce these risks by increasing the rigidity of the interior of the bag 1 to reduce the movement of the bag 1.
[0058] The partition 2 is set to be inflatable, which can ensure the shape of the liquid bag and prop up the bag body. When there is less fluid inside, it can also reduce the deformation and movement of the bag body 1 to a certain extent, thereby reducing the risk of the bag body 1 being scratched or damaged.
[0059] In other embodiments, the partition member 2 does not include the inflation portion 202 , and the partition member 2 is configured to be inflatable and connected to the bag body 1 after being filled with air.
[0060] Continue reading Figure 8 The first limiting portion 2021 is located below the second limiting portion 2022, which is the one away from the inner wall of the bag body 1. The first limiting portion 2021 is provided with an inflation valve 5, and the valve opening of the inflation valve 5 is downward. The inflation valve 5 is arranged on the side of the inflation portion 202 away from the inner wall of the bag body 1, which can prevent the inflation valve 5 from scratching the bag body 1. Of course, this is not restrictive, and the inflation valve 5 can also be arranged in the area of the partition 2 away from the inner wall of the bag body 1, such as Fig. 9 As shown in FIG. 1 , an inflation valve 5 is arranged in the middle area of the partition member 2 , and the inflation valve opening is also located in the middle area.
[0061] In addition, the bag body 1 is formed by splicing a plurality of bag pieces, which are sealed by laser welding or ultrasonic welding after splicing. Of course, this is not restrictive. The bag body 1 can also be formed in one piece. The liquid bag also includes an outer bag (not shown in the figure), which wraps and covers the bag body 1. The outer bag wraps and covers the bag body 1, thereby effectively preventing the bag body 1 from being worn and leaking during transportation; this design not only increases the overall sealing of the liquid bag, but the outer bag also provides an extra layer of protection for the inner bag (bag body 1), which can enhance the overall strength of the bag body 1, which is particularly important for liquid bags that need to withstand higher pressure or weight.
[0062] The materials of the bag body 1 and the partition 2 can be the same or different. The materials can be PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride) and TPU (thermoplastic polyurethane), or other film materials or sheet materials that can be formed into bags. The material is soft and can be deformed, and the shape depends on the container.
[0063] It should be noted that although the attached Figure 1 The shape of the bag body 1 is a rectangular parallelepiped, but this is not restrictive, and it can also be a pillow shape or other shapes. Those skilled in the art can set it according to actual conditions.
[0064] In other embodiments, a plurality of partitions 2 divide the fluid storage space 11 into a plurality of fluid compartments that are not connected to each other, and each fluid compartment is provided with a fluid inlet 12 and a fluid outlet 13 .
[0065] It should be noted that the present invention does not impose any restrictions on the specific location of the fluid inlet 12 and the fluid outlet 13. The fluid inlet 12 can be located in any area of the upper surface of the bag body 1, or in the middle and upper area of the side of the bag body 1. The fluid outlet 13 can be located in any area of the lower surface of the bag body 1, or in the bottom area of the side of the bag body 1. Those skilled in the art can set it according to actual conditions.
[0066] The fluid of the present invention is preferably a liquid, but may also be other fluids, such as a granular fluid.
[0067] It should be noted that although the liquid bag is drawn as a cuboid in the attached drawings, this is only for the convenience of illustration and description, because in actual use, the liquid bag is usually placed in a container or other rigid container, thereby limiting its shape to a cuboid. If there is no restriction of an external rigid container, since the liquid bag itself is made of flexible material, its shape is usually an arc after being filled with fluid.
[0068] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings.
