Description

  The present invention relates to a box-type sandbag.

  Box sandbags are sometimes used to construct simple structures. For example, a box-type sandbag is used when a temporary building or a defensive wall must be created immediately on the battlefield.

  Box sandbags usually have three or more side walls. The space surrounded by the side walls is filled with the contents so that it can function as a simple wall. The contents are generally procurable locally, for example, earth and sand, crushed stone, rock, gravel, concrete, or a mixture thereof, or a bag of these. As a result, the box-type sandbag can be protected against a direct fire power such as a small bullet or a rocket bullet or a curved fire power such as a cannonball, and functions as a sufficient protective wall although it is temporary.

  The side wall of the box-type sandbag is generally a wire mesh. The wire mesh is lighter than, for example, a wall surface made of a metal plate, and a certain degree of strength can be expected. In addition, the side wall made of a wire mesh can be easily hinged so that one side wall can be rotated with respect to the other side wall. Also suitable.

In order to further reduce the weight of the box-type sandbag and improve its handling, a technique is also known in which the side wall of the box-type sandbag is made of a film material such as cloth.
Since the side wall can be reduced in weight by using the side wall as a film material, the entire box-type sandbag becomes light. In addition, the side wall that is a metal mesh can be folded only at a portion where the side walls are connected in a hinge shape and cannot be folded in the middle of the side wall, but the side wall that is a film material is not only a connection portion between the side walls but also a side wall. Because it can be folded anywhere, this box-type sandbag is also easy to handle.

By the way, although it is a box-shaped sandbag made of a film material having various advantages, it is not without its points to be solved.
As described above, the box-type sandbag is used by putting contents in a space surrounded by side walls. As a result, it is possible to construct a temporary defensive wall or a building, but there are cases where it is desired to remove a temporary defensive wall or the like. And when removing a box-type sandbag, it is necessary to take out the contents put into the above-mentioned space inside a box-type sandbag.
However, in the case of a box-shaped sandbag made of a film material, the side wall is usually a series of adjacent side walls or is completely fixed by sewing, so that the contents can be taken out from the above-mentioned space. Can only lift the contents from above the space. The labor and cost are excessive.

  This invention makes it the subject to provide the box-type sandbag which the side wall which made it easy to remove the content from the space enclosed by the side wall in the case of the removal was made from the film | membrane material.

In order to solve the above-mentioned problems, the present inventor proposes the following invention.
The present invention has at least three side walls made of a film material, each of which is a rectangle of the same height, each having a vertical vertical side in both width directions and a horizontal horizontal side in both vertical directions. And a box shape that is formed by arranging the side walls in an annular shape as a whole, and is used by putting the contents in a space that is surrounded by the side walls and that is open at the top and bottom. It is a sandbag.
That is, the present invention is a box-type sandbag that is made of a film material and is light and has high handling properties.
And two adjacent vertical sides of the adjacent side wall in the box-type sandbag, together with the adjacent vertical side, constitute a joint part that connects the adjacent side walls to each other, and at least the joint part One is a releasable joint part that is freely releasable to connect the two side walls connected by the joint part. By releasing the connection of the two side walls at the releasable joint part, The space can be opened from the side surface to the outside.
In the box-type sandbag according to the present invention, two adjacent vertical sides of adjacent side walls constitute a joint portion that can rotate with each other. The joint part can be configured by, for example, sewing two vertical sides together. And at least 1 of the joint part of this box-type sandbag is made into the releasable joint part by which the connection of side walls was made releasable. Therefore, the box-type sandbag of this application can open | release the side surface of the space enclosed by the side wall with respect to the exterior by canceling | releasing connection of two side walls by the said releasable joint part. All of the joints may be releasable joints, but this need not be the case.
Thereby, this box-type sandbag can take out the content put in the space enclosed by the side wall from the side surface, when performing the withdrawal. This is much easier and more cost effective than removing the contents from the upper side of the space surrounded by the side walls.
As described above, the side wall is originally rectangular in shape, but since it is made of a film material, each side wall is placed when the contents are put into a space surrounded by the side wall and opened up and down. May bulge outward. In that case, the side wall is not “rectangular” in an accurate sense as used at least in mathematics. However, even in such a case, in the present invention, the condition that the side wall is rectangular is satisfied. To do.

There are three or more side walls as described above. This is because the space surrounded by the side walls cannot be created unless there are at least three side walls. For example, four or more side walls can be used. In that case, the shape of the space surrounded by the side walls when viewed in plan can be made rectangular, or can be made triangular depending on the width of each side wall. When the number of side walls is four or more, the number of sides of the polygon when the space surrounded by the side walls is viewed in plan matches the number of side walls at the maximum, but the space surrounded by the side walls Depending on the number of side walls and the width of each side wall, the shape in plan view can be a quadrangle or a triangle.
When the number of the side walls is four or more, the box sandbag of the present application can be as follows. That is, each of the spaces is made of a film material that has a vertical vertical side in both width directions and a horizontal horizontal side in both vertical directions, and is a rectangle having the same height as the side wall. In addition, at least one partition wall that divides the space into a plurality of divided spaces is provided, and the two vertical sides of the partition wall are the vertical sides of the side wall or the vertical sides of the other partition walls. Along with a side, the adjacent partition wall and the side wall are connected to each other, or the adjacent partition walls are connected to each other to form a joint portion, and at least one of the joint portions is connected at the joint portion And at least one of the side walls and at least one of the partition walls. The partition and Connection by releasing the all the plurality of the divided spaces may be made openable to the outside from the side surface.
A partition can be provided inside the space surrounded by the side walls. By providing the partition wall, the self-supporting property of the box-type sandbag can be increased, thereby facilitating the operation of putting the contents into the box-type sandbag. Moreover, the above-mentioned partition functions also to raise the intensity | strength of a box-type sandbag, and by extension, the intensity | strength of the constructed defense wall. On the other hand, since the partition wall is made of a film material like the side wall, the lightness of the box-type sandbag and the good handling property are not impaired.
By connecting the vertical sides at both ends in the width direction to the vertical sides of the side walls or the vertical sides of other partitions, the both ends in the width direction are connected to the side walls or other partitions. It is in a state. The vertical side of the partition wall and the vertical side of the side wall, or the vertical side of the partition wall and the vertical side of the other partition wall constitute a joint part similar to the above-described joint part formed by the vertical sides of the two side walls. And a part of the joint part becomes a releasable joint part similar to the above-mentioned releasable joint part. The releasable joint already described is capable of releasing the connection between the two side walls connected there. In this case, the releasable joint is located between the partition wall and the side wall connected there. Or the connection between the partition wall connected thereto and another partition wall can be released.
The space surrounded by the side wall of the box-type sandbag having the partition walls is partitioned by the partition walls into a plurality of divided spaces. The releasable joint portion is provided so that all of the plurality of divided spaces can be opened from the side surface to the outside. All of the joints may be releasable joints, but only the joints that are necessary to allow all of the plurality of divided spaces to be opened from the side to the outside are releasable joints. Is enough. Thereby, the contents put in all the divided spaces can be taken out from the side surface.
The releasable joint to which the partition wall is connected may be connected to the partition wall and the side wall, or may be connected to the partition wall and another partition wall, but only two partition walls or side walls are connected to it. For example, three side walls, four side walls, and two side walls may be connected to one releasable joint. The same applies to a normal joint.

At least one of the divided spaces may be either a triangle or a quadrangle in plan view. In addition, the shape of the divided space in the box-shaped sandbag in the plan view may or may not be the same. For example, even if the shape in the plan view is all triangular, Even if it is a rectangle, both a triangle and a rectangle may exist. Note that “triangles” and “quadrangles” are not used in a strict sense as used in mathematics. As described above, each side wall may bulge outward when the contents are put in a space surrounded by the side wall and opened at the top and bottom. In that case, at least one side of the “triangle” or “quadrangle” shape in the plan view of the divided space may bulge outward. Even in such a case, it is assumed that the condition that the divided space is either a triangle or a quadrangle in plan view is satisfied. The same applies to the following.
The divided space may be all quadrangular in plan view. By doing so, it becomes easy to make the shape of the space surrounded by the side wall a quadrangle when viewed in plan. A defense wall or the like constructed with such a box-type sandbag is square when viewed in plan, and is convenient for combining with other box-type sandbags.
There may be four or more partition walls, and at least one of the divided spaces may be a rectangular space surrounded by the partition walls.

The configuration of the releasable joint portion may be any way. When a plurality of releasable joint parts are included in one box-type sandbag, the structures of all the releasable joint parts may or may not be the same.
At least one of the releasable joint portions is a horizontal provided in the vicinity of each vertical side of the wall member connected by the releasable joint portion when the side wall and the partition wall are defined as a wall member. And a plurality of the wall members by penetrating the plurality of the rings through the plurality of the rings. May be connected to the rod, and the wall member may be disconnected from the rod by pulling the rod upward from the wheel. By pulling out the through rod, it is convenient because the fixing of the wall material can be released collectively.
At least one of the releasable joint portions is provided in the vicinity of each vertical side of the wall member connected by the releasable joint portion when the side wall and the partition wall are defined as a wall member. It is possible to insert the thick part thicker than the other part of the wall material and the thick part, the width of the opening is narrower than the thick part, and wide toward the back. A connecting rod arranged in a vertical direction and having a plurality of grooves opened at least at the lower ends thereof, and running in the vertical direction, and inserting the thick portion into the grooves, The wall material can be connected to the connection rod, and the connection of the wall material to the connection rod is released by pulling the connection rod upward as the thick portion is pulled out from the groove. You may be able to do it. By pulling out the connecting rod, it is convenient because the fixing of the wall material can be released collectively.
At least one of the releasable joint portions is provided in the vicinity of each vertical side of the wall member connected by the releasable joint portion when the side wall and the partition wall are defined as a wall member. A locking piece capable of locking the linear body, and a linear body capable of locking an appropriate portion in the length direction to the plurality of the locking pieces, the linear body being The wall member can be connected to the releasable joint by engaging the plurality of the locking pieces, and by releasing the locking of the linear body to the locking pieces, The connection of the wall material to the releasable joint portion may be released.

  Hereinafter, preferred first to fourth embodiments of the present invention will be described with reference to the drawings. In addition, in each embodiment, the common code | symbol shall be attached | subjected to the common object and common description shall be abbreviate | omitted by the case.

  A box-shaped sandbag 101 according to an embodiment of the present invention is shown in FIG. The box-shaped sandbag 101 shown in FIG. 1 is in an assembled state. Since most or all of the box-type sandbag 101 is made of a film material, it can be folded when not in use.

The box-shaped sandbag 101 includes a large number of side walls 110. The side wall 110 is made of a film material. As the membrane material, for example, a sheet made of a synthetic fiber nonwoven fabric such as polyester, a sheet made of a synthetic fiber woven fabric, or a sheet coated with a synthetic resin can be used. This also applies to the film materials that appear below.
The side walls 110 are all rectangular. The side wall 110 includes a vertical side 111 that is a side perpendicular to both sides in the width direction, and a horizontal side 112 that is a horizontal side on both sides in the vertical direction. All side walls 110 are equal in height. On the other hand, the widths of all side walls 110 need not be equal. However, in this embodiment, the widths of all the side walls 110 are equal. More specifically, in this embodiment, all side walls 110 are squares of the same size.

The number of side walls 110 is three or more. In this embodiment, the number of side walls 110 is 14. As shown in FIG. 1, there are five side walls 110 on the front side and the back side in FIG. 1, and two side walls 110 on the right side and the left side in FIG.
Each side wall 110 is connected to the adjacent side wall 110 and its vertical side 111. Thereby, the side wall 110 is connected in an annular shape. More specifically, as shown in FIG. 1, the side walls 110 are arranged so as to be square in plan view. As will be described later, the contents are placed in a space 130 that is surrounded by the side wall 110 and that is open at the top and bottom of the square in plan view. Thereby, this box-shaped sandbag 101 can construct a temporary defense wall or a building. The contents are generally those that can be procured locally, such as soil, sand, crushed stone, Ryukyu lime, rubble, concrete, or a mixture thereof, or a bag of these.

  A portion where the side walls 110 are connected to each other is a joint portion 113 in the present application. Each side wall 110 may be rotatable with respect to the adjacent side wall 110 around the joint portion 113 as an axis. The structure of the joint part 113 should just be able to connect adjacent side walls 110 via the joint part 113. FIG. Although not limited to this, the joint portion 113 in this embodiment is configured by stitching the vertical sides 111 of adjacent side walls 110 together except for a releasable joint portion described later. Although not limited to this, the range of stitching in this embodiment extends from the upper end to the lower end of the side wall 110.

Although not necessarily required, partition walls 120 are provided vertically and horizontally in the space surrounded by the side walls 110 of this embodiment (FIGS. 1 and 2).
The partition wall 120 is configured similarly to the side wall 110. All the partition walls 120 are rectangular. The partition wall 120 includes a vertical side 121 that is a side perpendicular to both sides in the width direction, and a horizontal side 122 that is a horizontal side on both sides in the vertical direction. All the partition walls 120 have the same height, and the side wall 110 has the same height. On the other hand, the widths of all the partition walls 120 need not be equal. However, in this embodiment, all the partition walls 120 have the same width. More specifically, in this embodiment, all the partition walls 120 are squares having the same size.
The partition wall 120 divides a space 130 surrounded by the side walls 110 into a plurality of divided spaces 131. Although not limited to this, five partition walls 120 of this embodiment are arranged in the left-right direction in FIG. 1, and two partition walls 120 are arranged in four rows in the front-rear direction in FIG. As a result, the partition wall 120 divides the space 130 surrounded by the side wall 110 into 5 × 2 = 10 divided spaces 131. Although not limited to this, the divided spaces 131 in this embodiment are all quadrangular in plan view, and more specifically, square in plan view.

The vertical sides at both ends of the partition wall 120 are connected to the vertical sides 111 of the side wall 110 or the vertical sides 121 of the other partition walls 120.
Of the vertical sides 121 of the partition walls 120, those connected to the vertical sides 111 of the side walls 110 are actually connected to the joint portions 113 of the two side walls 110 in this embodiment. The partition wall 120 in this embodiment may be configured to be rotatable about the joint portion 113 as the two side walls 110 connected to the joint portion 113. The method of connecting the vertical side 121 of the partition wall 120 to the vertical side 111 of the side wall 110 is not limited to this as long as the joint portion 113 is not a releasable joint portion described later, but can be stitched.
In the vertical side 121 of the partition wall 120, a joint portion 123 similar to that described above is configured at a portion connected to the vertical side 121 of the other partition wall 120. In this embodiment, among the vertical sides 121 of the partition walls 120, the vertical sides 121 of the four partition walls 120 are abutted against the joint portions 123 connected to the vertical sides 121 of the other partition walls 120. The connecting method of the vertical sides 121 of the four partition walls 120 in the joint portion 123 is not limited to this as long as the joint portion 123 is not a releasable joint portion described later, but can be stitched.

Some of the joint portions 113 and 123 described above are releasable joint portions. The releasable joint part is a member that can freely release the connection between the side wall 110 and the partition wall 120 connected to the joint part 113 or the joint part 123 and the joint part 113 or the joint part 123.
In the example of FIG. 2, a portion with a black circle symbol is a releasable joint. The portion marked with a white circle is convenient to be a releasable joint, but is not necessarily a releasable joint, but is a joint 113 or a joint 123.
It may be possible that all the joint portions 113 and the joint portions 123 are releasable joint portions, but this is not the case in this embodiment. Which of the joint part 113 and the joint part 123 is the releasable joint part means that the connection between the side wall 110 and the partition wall 120 connected to the releasable joint part and the joint part 113 or the joint part 123 is released. By doing so, it is determined based on the rule that the condition of allowing all of the divided spaces 131 to be opened to the outside from the side surface is satisfied. This rule will be described in detail later.

  The releasable joint portion is configured as follows, for example. The examples of the three types of releasable joints can be broadly divided into the following, but the three types of releasable joints can be freely selected as any of the releasable joints. It is also possible to adopt the part for one box-type sandbag 101.

The releasable joint portion may be configured as shown in FIG. In FIG. 3, the side wall 110 and the partition wall 120 are not distinguished from each other and are represented as a wall material 190.
In the example of the releasable joint shown in FIG. 3, two wall members 190 are connected to the releasable joint.
In the wall member 190L located on the left side in FIG. 3, a plurality of ring members 191L made of a film material are attached at a predetermined interval at a predetermined interval. The ring member 191L is a ring-shaped tape-shaped film material cut to a predetermined width, and is attached to the wall material 190L by, for example, sewing. The ring member 191L is not limited to this, but in this embodiment, the ring member 191L is provided over the entire length of the vertical side of the wall member 190L located on the left side in FIG.
On the other hand, ring members 191R are provided at predetermined intervals on the wall member 190R located on the right side in FIG. The configuration of the ring member 191R and how to attach it to the wall member 190R are the same as those of the ring member 191L. The ring member 191R is provided over the entire length of the vertical side of the wall member 190R so as to alternate with the ring member 191L. The ring member 191R can be positioned so as to overlap the ring member 191L in plan view.
The releasable joint shown in FIG. 3 is also provided with a rod 192 that can penetrate the plurality of ring members 191L and the plurality of ring members 191R together, and can move up and down as viewed from the arrow. Yes. The wall member 190L and the wall member 190R are rotatably connected to each other by penetrating the ring member 191L and the ring member 191R together by the rod 192 that is a metal rod-like body. The rod 192 can be pulled upward. Thereby, the connection between the wall material 190L and the wall material 190R can be released.
A modification of the releasable joint shown in FIG. 3 is shown in FIG.
The releasable joint shown in FIG. 4 has almost the same configuration as the releasable joint shown in FIG.
The releasable joint shown in FIG. 4 is shown in FIG. 3 only in that the other wall material 190L1 is connected to the wall material 190L and the other wall material 190R1 is connected to the wall material 190R. Different from the releasable joint. The releasable joint portion is formed by pulling the rod 192 upward, so that the four wall members 190L, 190L1, 190R, and 190R1 are integrated with the wall member 190L and the wall member 190L1, and the wall member 190R is integrated. And it becomes possible to divide into wall material 190R1. Thus, the wall material connected to the releasable joint portion does not need to be divided one by one.
However, as shown in FIG. 4, for example, when there are four wall members 190L, 190L1, 190R, and 190R1, the vertical sides of the respective wall members 190L, 190L1, 190R, and 190R1 are overlapped in a plan view. By providing the ring member in this way, it is possible to divide each of the four wall members 190L, 190L1, 190R, 190R1 one by one.

The releasable joint portion may be configured as shown in FIG. In FIG. 5, the side wall 110 and the partition wall 120 are not distinguished from each other and are represented as the wall material 190.
The releasable joint shown in FIG. 5 includes a connecting rod 194. The connecting rod 194 is a rod-like body and has a length corresponding to the height of the wall material 190. The connecting rod 194 is also provided with a groove 194A extending over the entire length in the length direction. The groove 194 </ b> A does not necessarily exist over the entire length of the connecting rod 194 but needs to reach at least the lower end of the connecting rod 194. The groove 194A is shaped so that its width increases toward the inside.
The wall member 190 is releasably connected to the connecting rod 194. As shown in FIG. 5B, the wall member 190 used in combination with the connecting rod 194 is provided with a thick portion 195 having a larger thickness than other portions of the wall member 190 in the vicinity of the vertical side thereof. It has been. The thick portion 195 is formed by folding the wall material 190 in the vicinity of the vertical side, and inserting, for example, a metal rod-like body or an insertion member 196 that is a rope into the inside of the ring-shaped portion formed by folding the wall material 190. can do. The thick portion 195 can be inserted into the groove 194A of the connecting rod 194 from the lower end side of the connecting rod 194, and has a shape that cannot be removed from the opening along the length direction of the groove 194A.
By inserting the thick portion 195 into the groove 194 </ b> A of the connecting rod 194, the wall member 190 can be releasably connected to the connecting rod 194 at its vertical side. Further, the connection of the wall member 190 to the connection rod 194 is released by pulling the connection rod 194 upward.
According to this method, basically, each wall member 190 can be connected to the connecting rod 194 one by one and can be disconnected from the connecting rod 194 one by one. However, as shown in the upper side of FIG. 5B, if the configuration in which the wall material 190A is connected to the wall material 190 is adopted, the two wall materials 190 are connected to the connecting rod 194 while being integrated. It is also possible to release the connection with the connecting rod 194 while the two wall members 190 are integrated.

The releasable joint portion may be configured as shown in FIG. In FIG. 6, the side wall 110 and the partition wall 120 are not distinguished from each other and are represented as the wall material 190.
In the example of the releasable joint shown in FIG. 6, two wall members 190 are connected to the releasable joint.
The wall member 190L located on the left side in FIG. 6 is not necessarily limited to this at a predetermined interval. For example, a plurality of locking members 197L made of metal and curved in a hook shape are attached at a predetermined interval. . The locking member 197L is not limited to this, but in this embodiment, the locking member 197L is provided over the entire vertical side of the wall member 190L located on the left side in FIG.
On the other hand, the wall member 190R located on the right side in FIG. 6 is provided with locking members 197R at predetermined intervals. The configuration of the locking member 197R is the same as that of the locking member 197L. The locking member 197R is provided over the entire length of the vertical side of the wall member 190R, for example, alternately with the locking member 197L.
The releasable joint shown in FIG. 6 also includes a restraining membrane material 198. The restraining film material 198 is a film material, and its length in the vertical direction is made to coincide with the length in the vertical direction of the wall material 190.

A modification of the releasable joint shown in FIG. 6 is shown in FIG.
The releasable joint shown in FIG. 7 has almost the same configuration as the releasable joint shown in FIG.
The releasable joint shown in FIG. 7 is shown in FIG. 6 only in that another wall material 190L1 is connected to the wall material 190L, and another wall material 190R1 is connected to the wall material 190R. Different from the releasable joint. According to this releasable joint part, the connection of the four wall members 190L, 190L1, 190R, and 190R1 and the release thereof are performed by integrating the wall member 190L and the wall member 190L1, and also integrating the wall member 190R and the wall member 190R1. It is done in the state.

Next, a method for using the box-type sandbag 101 will be described.
In order to use the box-type sandbag 101, first, the box-type sandbag 101 is installed in a suitable place for constructing a defense wall or a building. The space X surrounded by the side wall 110 of the box-type sandbag 101 is filled with the contents X in more detail, in each of the divided spaces 131 in which the space 130 is divided in this embodiment ( FIG. 8 (a)). The contents X are basically filled in all the divided spaces 131.
The height of the box-shaped sandbag 101 is not limited to this, but is generally about 60 cm to 1 m. If necessary, an appropriate heavy machine may be used for the work of filling the contents X into the divided space 131.
Note that when the contents X are placed in the space 130 or the divided space 131 obtained by dividing the content X, the side wall 110 may bulge to the outside. In that sense, FIG. 8 can be said to be a schematic one that lacks some accuracy. The same applies to FIG. 9 described below.

In this state, the box-type sandbag 101 functions as a defense wall or a building. If the box-type sandbag 101 is insufficient to function as a defense wall or a building, another box-type sandbag may be combined.
And when the box-shaped sandbag 101 is no longer needed, it is withdrawn.

  When the box-type sandbag 101 is withdrawn, the connection of the side wall 110 or the partition wall 120 connected to the releasable joint part to the releasable joint part is released at the releasable joint part. In the case of the box-type sandbag 101 shown in FIG. 8, in the releasable joint portion existing at the black circles at the left and right ends in FIG. Disconnect. Then, the side wall 110 released from the connection to the releasable joint is rotated about the joint opposite to the side connected to the releasable joint so as to be positioned above and below the left and right ends of the box-type sandbag 101. The side surfaces of the four divided spaces 131 in total (side surfaces on the outer side in the horizontal direction in FIG. 8B) are opened to the outside. Each divided space 131 is filled with the contents X, but the contents X contained in the divided spaces 131 whose side surfaces are opened can be easily removed from the opened side surfaces of the divided spaces 131 to the outside. Can do. FIG. 8B shows a state in which the contents X are removed from a total of four divided spaces 131 at the left end and the right end of the box-type sandbag 101.

  Next, in this case, in the box-type sandbag 101 of FIG. 8C, the releasable joint part with the second black circle from the left and the releasable joint part with the second black circle from the right Then, the connection of the partition wall 120 to the releasable joint portion is released. Then, the partition wall 120 released from the connection with the releasable joint part is rotated about the joint part opposite to the side connected with the releasable joint part as an axis, and the second upper and lower parts from the left of the box-type sandbag 101 are rotated. The two outer surfaces in the left-right direction of the two divided spaces 131 and the upper and lower two divided spaces 131 from the right are opened to the outside. Then, the contents X contained in the four divided spaces 131 are removed to the outside from the opened portion. FIG. 8C shows a state in which the contents X are removed from the upper and lower two divided spaces 131 from the left of the box sandbag 101 and the second upper and lower divided spaces 131 from the right. Yes.

Then, the partition wall 120 released from the connection with the releasable joint part is rotated around the joint part on the single side with respect to the side connected with the releasable joint part, and the box-shaped sandbag 101 has a central upper and lower 2 The left and right side surfaces of one divided space 131 are opened to the outside. Then, the contents X contained in the two divided spaces 131 are removed to the outside from the opened part. FIG. 8D shows a state in which the contents X are removed from the two upper and lower divided spaces 131 in the horizontal direction of the box sandbag 101.
In this way, all the contents X filled in the space 130 of the box-type sandbag 101 are removed from the space 130.
As is clear from the above description, any of the divided spaces 131 is open to the outside at any stage of removal of the box-shaped sandbag 101. The releasable joint is provided on the box-type sandbag 101 so that it can be achieved. In other words, the box-type sandbag 101 of this embodiment is selected so as to be able to do so, and a necessary part of the joint parts is a releasable joint part.

  Since the box-shaped sandbag 101 from which the contents X have been removed from the space 130 is basically made of a film material, it may be removed by a known method such as folding or winding.

Assuming that there is a certain box-type sandbag 101, all the split spaces 131 are required to be released so that one of the side surfaces is open to the outside. The number and position of are not necessarily one.
For example, in the box-type sandbag 101 shown in FIG. 8 as described above, not only the joints with black circles but also the joints with white circles are set as releasable joints. It is possible.
In that case, for example, from the state in which all the divided spaces 131 shown in FIG. 9A are filled with the contents X, they are connected to the releasable joint as shown in FIG. 9B, for example. The connection of the side wall 110 and the partition wall 120 to the releasable joint portion is released, and then the contents X can be removed from the open side surface of each divided space 131. If the method for removing the box-shaped sandbag 101 shown in FIG. 9 is executed, any side surfaces of all the divided spaces 131 are already open to the outside in the state shown in FIG. 9B. Therefore, unlike the case where the method for removing the box-shaped sandbag 101 shown in FIG. 8 is executed, it is not necessary to release the connection of the side wall 110 or the partition wall 120 to the releasable joint portion step by step.
When the contents X are removed from all the divided spaces 131 (FIG. 9C), the remaining box-shaped sandbag 101 may be removed by folding, winding or the like.

  As described above, the box-shaped sandbag 101 in which the space 130 surrounded by the side wall 110 is divided into 5 × 2 = 10 divided spaces 131 is, for example, as shown in FIG. Even if the releasable joint portion is provided at the position, all of the divided spaces 131 are open to the outside on either side.
