The back hole 9 is provided with an internal eyelet fitting 20 and an eyelet 21 made of anti-slip rubber that removably covers the internal eyelet fitting 20.
The combined outer diameter of the two eyelets is larger than the inner diameter of the eyelet tool 21.

Embodiment An embodiment of this invention will be described below with reference to the drawings. Reference numeral 1 denotes an opening, and the upper peripheral edge 3 of a flat square bag body 2 having an opening 1 at the upper part is folded back to form a double upper edge 4. A front hole 8 and a back hole 9 are formed at the same positions across the front surface 5 and back surface 6 of the bag body 2 near the left edge 7 of the upper edge 4, and the right side of the upper edge 4 Several holes 11 are bored except for the edge 10, and an eyelet fitting 1 is formed by penetrating the bottom corner portion of the bag body 2 over the front surface 5 and the back surface 6 located below the front and back surface holes 8 and 9.
A lower hole 13 is formed with a carrying strap 14.
The central part 15 of the carrying strap 14 is placed on the outer periphery of the right edge 10, and the end strap part 16 of one of the carrying straps 14 is sequentially inserted into the holes 11, 11... bored in the upper edge 4 of the surface 5. 8 through the hole 9 on the back side and the lower hole 13, and the other end string part 17 of the carrying strap 14 is inserted through the holes 11, 11 drilled in the upper edge 4 of the back side 6 sequentially. It is inserted into the surface hole 8 from the surface hole 9 and also inserted into the lower hole 13, and the binding portion 18 is formed by making both end string portions 16 and 17 prevent from coming out from the lower hole 13,
In addition, the front hole 8 and the back hole 9 are provided with an internal eyelet fitting 20 and an eyelet 21 made of anti-slip rubber that removably covers the internal eyelet fitting 20. The diameter is eyelet tool 21
The inner diameter of the bag body 2 is larger than that of the inner diameter of the bag body 2.
is made of a vertically long belt-shaped sheet, has a pleat in the bottom part 19, has an opening 1 in the upper part, folds back the upper peripheral edge 3 to form a double upper edge part 4, and has the entire length of the left and right edges 7, 10. It is formed by thermal welding over the following steps.

Effects of the invention This invention has the above-mentioned configuration, and the upper peripheral edge 3 of the flat square bag body 2 having the opening 1 at the upper part is folded back to form a double upper edge part 4. A front hole 8 and a back hole 9 are formed near the left edge 7 of the edge 4 at the same positions across the front surface 5 and the back surface 6 of the bag body 2, and a number of holes are formed excluding the right edge 10 of the upper edge 4. holes 1
1, and a lower hole 13 having an eyelet fitting 12 is formed in a lower corner portion located below the front and back holes 8 and 9 of the bag body 2, passing through the front surface 5 and the back surface 6, and In addition, the center part 15 of the carrying strap 14 is connected to the right edge 10.
located on the outer periphery of one end of the carrying strap 14.
6 and holes 11, 11, 11, 11, 11, 11, 6, and 6 formed in the upper edge 4 of the surface 5, respectively.
The hole 11 is inserted into the upper edge 4 of the back surface 6 through the hole 11, which is sequentially inserted through the surface hole 8, the back hole 9, and the lower hole 13. 11... and then the back hole 9, the front hole 8, and the lower hole 13. By tightening the opening 1 with the carrying strap 14, the state shown in FIG. 7 is achieved, which is extremely convenient for carrying by hanging it on the shoulder.

Furthermore, by forming a lower hole 13 with an eyelet fitting 12 penetrating the front surface 5 and the back surface 6 at the lower corner portion located below the front and back holes 8 and 9 of the bag body 2, a carrying strap 14 is formed. The lower hole 13 in which the binding portion 18 is provided by inserting the string portions 16 and 17 at both ends of the hole 13 does not require complicated machining, saves labor costs, and is easy to manufacture. The surface hole 9 is equipped with an internal eyelet fitting 20, and an eyelet fitting 21 made of anti-slip rubber that removably covers the internal eyelet fitting 20.
This is to prevent the carrying strap 14 inserted therethrough from slipping and loosening when the opening 1 is tightened as shown in FIG.
It can be carried safely without the items coming loose or falling out.

Furthermore, it has a simple structure, is suitable for mass production, and can be provided at low cost, and has many practical effects.
