As shown in FIG. 1, the packing bag 1 according to the present embodiment is mainly made of a sheet material, and has a hollow portion inside for accommodating an object to be packed 15 (for example, a material such as an angle steel material). It is provided with a bag main body 2 that covers the entire surface of the packaged object 15, and two belts 5 that are fixed to _{the outer bottom surface 2a 1 of the bag main body 2.}
Further, the bag main body 2 constituting the packing bag 1 according to the above-described embodiment is provided with an opening 3 for putting in and taking out the object to be packed 15 in the hollow portion thereof, and an opening / closing tool 4 for opening and closing the opening 3. It is equipped with.
In addition, in the packing bag 1 according to the present embodiment, the belt 5 is fixed only to _{the outer bottom surface 2a 1 of the bag main body 2.}
Then, in the packing bag 1 according to the present embodiment, as shown in FIGS. 2A and 2B, the belt 5 is placed on the peripheral side surface of the bag body 2 in a state where the packed object 15 is housed in the bag body 2. It is used by winding it in a bag.

In the packing bag 1 according to the present embodiment as described above, the belt 5 is _{fixed only to the outer bottom surface 2a 1} of the bag body 2, but is not fixed to the side surface 2d or the top surface 2b of the bag body 2. ..
Therefore, in the packing bag 1 according to the present embodiment, when the belt 5 is wound around the peripheral side surface of the bag body 2 on the lateral side, the belt is arranged on the side surface 2d or the top surface 2b of the bag body 2. 5 is not pulled by the sheet material constituting the bag body 2.
Therefore, as shown in FIG. 2B, after the belt 5 is wound around the peripheral side surface of the bag body 2, the tip portion 5a of the belt 5 is pulled up vertically upward to be packed together with the packing bag 1. When the 15 is hung, the object to be packed 15 can be tightly bound by the belt 5 from the outside of the bag body 2.
That is, according to the packing bag 1 according to the present embodiment, the packed object 15 can be hung and transported from the outside of the bag main body 2 while maintaining a state of being tightly bound by the belt 5.
Therefore, according to the packing bag 1 according to the present embodiment, it is preferable to prevent a part of the packed object 15 from falling off from the belt 5 and falling while the packed object 15 is suspended and transported. be able to.
Further, even if the packaged object 15 is not sufficiently bound by the belt 5, the entire surface of the packaged object 15 is covered by the bag body 2, so that the packaged object being transported by the bag body 2 is packed. It is possible to prevent the object 15 from falling.

More specifically, in the packing bag 1 according to the present embodiment, for example, an annular body having the same circumference is used as the belt 5 (see FIG. 6 (b) in the latter stage).
Further, in the packing bag 1 according to the present embodiment, the central portion 5b in the longitudinal direction of the elongated belt 5 having an annular shape as described above is fixed to _{the outer bottom surface 2a 1 of the bag body 2.} ..
Then, in the packing bag 1 according to the present embodiment, the longitudinal direction when the belt 5 is deformed into an elongated shape as described above is the arrangement direction of the packaged object housed in the bag main body 2 (the bag in FIG. 1). It is arranged so as to intersect with the longitudinal direction of the main body 2) and, more specifically, to be substantially orthogonal to the arrangement direction of the packaged object.
In addition, in the packing bag 1 according to the present embodiment, each of the belts 5 composed of two sets of annular bodies is located on the outer bottom surface 2a ₁ at a position separated from each of the longitudinal end faces 2c of the bag body 2 by approximately the same distance. It is fixed.
Therefore, as shown in FIG. 1, the packing bag 1 according to the present embodiment is provided with two sets of loop-shaped handles at positions separated from each of the longitudinal end faces 2c in the bag body 2 by substantially the same distance. It is in the form of a bag.

Then, in the packing bag 1 according to the present embodiment as described above, the tip portion 5a side of each of the two belts 5 is wrapped around the peripheral side surface of the bag body 2 in the lateral direction, and the state is set to the bag body. When viewed from the end surface 2c side of 2 (see FIG. 2B), the tip portions 5a and 5a of the belt 5 are arranged so as to be symmetrical with the bag body 2 sandwiched between them, and the bag body 2 The distances from the top surface 2b to the tips 5a of the two belts 5 are substantially the same (see FIG. 2B).
Therefore, in the packing bag 1 according to the present embodiment, when the tip portions 5a of the belt 5 after being sacked are gathered together and hooked on a hook or the like and hung, they are housed in the bag main body 2. The belt 5 can be tightened on the peripheral side surface of the bag body 2 by the weight of the packaged object itself.
As a result, according to the packing bag 1 according to the present embodiment, the items to be packed contained in the bag main body 2 can be tightly tightened and fixed by the belt 5 while being bundled by the belt 5.

FIG. 3 is an image diagram showing a state in which a packed object packed in a packing bag according to the present invention is transported by a helicopter. The same parts as those shown in FIGS. 1 and 2 are designated by the same reference numerals, and the description of the configuration thereof will be omitted.
In the packing bag 1 of the form shown in FIG. 1 above, the fixing positions of the belts 5 and 5 from the end surface 2c of the bag body 2 are constant, and the two belts 5 are rotated around the bag body 2 in the lateral direction. The distances from the top surface 2b of the bag body 2 to the tips 5a of the two belts 5 when the bag is wound on the side surface are substantially the same.
Therefore, when the packed object 15 is packed using the packing bag 1 according to the present embodiment and the tip portion 5a of the belt 5 is suspended and held by, for example, a hook 11, the bag is as shown in FIG. The packaged object 15 housed in the main body 2 can be held substantially horizontally.
This means that it is difficult for a force such as pulling out from the bound portion of the belt 5 to act on the individual packages 15 bound by the belt 5.
Therefore, according to the packing bag 1 according to the present embodiment, it is unlikely that an accident will occur in which the packed object 15 breaks through the bag main body 2 and falls when the packed object 15 is transported.

Further, since the packing bag 1 according to the present embodiment is composed of the bag body 2 made of a sheet body and the belt 5 as described above, the packing bag 1 can be folded and stored compactly when not in use. ..
Therefore, according to the packing bag 1 according to the present embodiment, it is possible to provide the packing bag 1 having excellent storability.

In FIGS. 1 and 3, the case where the packing bag 1 according to the present embodiment includes two belts 5 made of an annular body is described as an example, but even if only one belt 5 is provided, the case is described. It is possible to exert the same action and effect as described above.
That is, when only one belt 5 is fixed to the outer bottom surface 2a ₁ of the bag body 2, this belt 5 is wrapped around the bag body 2 and the state is set to the end surface 2c side of the bag body 2. The tips 5a and 5a of the belt 5 are arranged symmetrically with the bag body 2 sandwiched between them, and the top surface 2b of the bag body 2 to the tips 5a and 5a of the belt 5 are arranged. The items to be packed by the packing bag 1 are configured so that the distances are substantially the same and the distances from the end faces 2c of the bag body 2 to the tips 5a and 5a of the belt 5 are substantially the same. When the 15 is suspended and held, the packaged object 15 housed in the bag main body 2 can be kept substantially horizontal.

Further, when the packaged object 15 is a long body, three or more belts 5 may be provided on _{the outer bottom surface 2a 1 of the bag body 2 for use.}
In this case, the individual belts 5 are wrapped around the bag body 2, and the arrangement of the tip portions 5a, 5a of the belt 5 when the state is viewed from the end surface 2c side of the bag body 2 sandwiches the bag body 2. The distances from the top surface 2b of the bag body 2 to the tips 5a and 5a of the belt 5 are substantially the same, and the attachment position of the belt 5 in the longitudinal direction of the bag body 2 is set. The belts 5 may be arranged so as to be symmetrical with respect to the center line in the longitudinal direction when viewed in a plan view, or the belts 5 may be evenly arranged in the longitudinal direction of the bag body 2.
Also in this case, when the packed object 15 packed by the packing bag 1 according to the present embodiment is suspended and held, the packed object 15 housed in the bag main body 2 can be kept substantially horizontal.

Further, in the packing bag 1 according to the present embodiment shown in FIGS. 1 and 2, the central portion 5b of the belt 5 made of an annular body deformed into an elongated shape is attached to the bag main body 2 by using a fixing member 6 (for example, a rivet or the like). It may be fixed to the outer bottom surface 2a ₁ of the (arbitrary selection component).
In this case, in the portion where the fixing member 6 is not installed, the belt 5 becomes relatively movable with respect to the surface of the bag body 2.
Further, the fixing strength of the fixed portion can be increased as compared with the case where the belt 5 is sewn to the outer bottom surface 2a _{1 of the bag main body 2.}
Therefore, when the object to be packed 15 is bound by the belt 5 from the outside of the bag body 2, it is possible to preferably prevent the belt 5 from being unintentionally detached from the bag body 2.
In FIGS. 1 and 2, a _{case where one fixing member 6 is provided at each intersection of the outer bottom surface 2a 1} of the bag body 2 and the belt 5 is described as an example, but the fixing member 6 is required. A plurality of them may be provided depending on the situation.

In the packing bag 1 according to the present embodiment, the length up to the tip portion 5a based on the fixed position (for example, the central portion 5b) of the belt 5 on _{the outer bottom surface 2a 1 of the bag body 2 is at least the length of the bag body 2.} It is advisable to set it at least twice the total length of the peripheral side surface in the lateral direction.
In this case, when the belt 5 is wound around the peripheral side surface of the bag main body 2 in the packing bag 1 according to the present embodiment, the binding effect of the packed object 15 by the belt 5 can be surely exhibited.
Further, in FIGS. 1 to 3, the case where the distance from the fixed position of the belt 5 (for example, the central portion 5b) on _{the outer bottom surface 2a 1 of the bag body 2 to the tip portion 5a of the belt 5 is made substantially uniform is given as an example.} However, if the distance from the top surface 2b of the bag body 2 to the tip portion 5a of the belt 5 after the belt 5 is wound around the peripheral side surface of the bag body 2 can be made substantially constant. The fixed position of the belt 5 does not necessarily have to be the central portion 5b of the belt 5.
In this case, since the number of windings of the belt 5 on the peripheral side surface of the bag body 2 in the lateral direction is relatively reduced, the binding effect of the object to be packed 15 by the belt 5 is slightly reduced, but the packing bag according to the present embodiment. When packing the object to be packed 15 by 1, the work of winding the belt 5 on the peripheral side surface of the bag main body 2 can be simplified. As a result, it is possible to provide a packing bag 1 that can be easily attached to and detached from the object to be packed 15.

In the packing bag 1 according to the present embodiment, an impermeable material may be used as the sheet material constituting the bag main body 2 (arbitrary selection component).
In this case, the packing bag 1 according to the present embodiment can also be used as a storage container for temporarily storing the packed object 15 such as materials. In this case, when the packed object 15 in the packing bag 1 according to the present embodiment is accommodated and stored, the packed object 15 can be protected from rainwater.

Subsequently, the detailed structure of the packing bag 1 according to the present embodiment will be described with reference to FIGS. 1 to 6.
FIG. 4 is a plan view of the packing bag according to the present invention in a state where the opening is opened. Further, FIG. 5 is a perspective view showing a state in which the opening of the packing bag according to the present invention is opened. The same parts as those shown in FIGS. 1 to 3 are designated by the same reference numerals, and the description of the configuration thereof will be omitted.
As shown in FIGS. 4 and 5, even if the bag body 2 of the packing bag 1 according to the present embodiment is configured so that the entire _{inner bottom surface 2a 2 of the bag body 2 is exposed when the opening 3 is fully opened.} Good (optional component).
In this case, the object to be packed 15 (for example, materials such as angle steel are stacked while being horizontally arranged) is placed on _{the inner bottom surface 2a 2} that is exposed when the opening 3 of the bag body 2 is fully opened, for example, a crane or the like.
