[Sheathing step] ----- S1

In this step, as shown in FIG. 2, as shown in FIG. 2, this step may be performed by weaving only a long sloping width in the longitudinal direction, and the predetermined width at one end in the lengthwise direction is woven by the first reinforcing portion 100, And the second reinforcing part 110 is woven with a predetermined width,

Preferably, the first reinforcing portion 100 and the second reinforcing portion 110 are woven in a double-woven form to firmly fix the upper end portion, which receives the greatest load, so that a large amount of heavy or heavy heavy contents such as refractory materials are inserted, Unlike the outer casing of a container bag, it is intended to prevent damage to the outer skin as well as economic and time loss due to the discharge of the contents.

[Bending and cutting steps of the envelope] ----- S2

As shown in FIG. 2, in the state where the outer skin is woven as described above, the outer skin 10 woven in the longitudinal direction is divided into four equal parts in the longitudinal direction to form the folding lines 120, (121) in a longitudinal direction that is cut from the upper end of one side to the middle part of the second reinforcing part (110).

[Section 1 Formation of adhesive preparation] ----- S3

3, the longitudinally opposite ends of the outer sheath 10, which is woven long in the longitudinal direction, and the outer sheath 10, which is formed by the folding line 120 and the folding line 121, The first folding part 130 is formed by folding the inside of the triangle on both sides of the folding line 121 on the basis of the folding line 121 as shown in FIG.

[Section 2 Formation of the adhesive preparation] ----- S4

4, the upper end of the envelope 10 is folded to the transverse center line of the first reinforcing part 100 in a state of being folded by the first folding part 130, 140 and then sewing the first folding unit 130 and the second folding unit 140 together.

[Section 3 Formation Step of Adhesive] ----- S5

5, when the first and second folding units 130 and 140 are formed as described above, the first folding unit 130 and the second folding unit 140 are overlapped with each other, 2 reinforcement portion 110 in the transverse direction to form a third folded portion 150. The first folded portion 130 and the second folded portion 130 in the sewed state are then folded in the transverse direction to the end of the folded portion 121, 7, in the state where the through hole 151 is formed between the folding section 140 and the third folding section 150, the transverse end of the third folding section 150 is in the sewed state The first folding unit 130 and the second folding unit 140 of the second folding unit 140 are sewn.

[Foam forming step] ----- S6

6, after the third folding unit 150 is formed, the folding line 120 divided into four equal parts in the longitudinal direction of the envelope 10 woven in the lengthwise direction is bent In the vertical direction, in the vertical direction.

[Stitching step of reinforcing member] ----- S7

7, after the foam is formed, the first folded portion 130 and the second folded portion 140 in the sewn state, which are the lateral ends of the third folded portion 150, And a reinforcing member sewing step for further sewing the reinforcing member 160 in the transverse direction on the sewed portion.

That is, the first reinforcing part 100 and the second reinforcing part 110 are woven and reinforced by a double weave, and the reinforcing member 160 is further provided to be more rigid, Is a measure for inserting the cover 170 to prevent the load of the contents from being damaged and preventing the cover 10 from being damaged or the hook 170 from falling off or coming off due to damage of the outer cover 10. [

[Sewing step of cover member] ----- S8

8, a hooking member 170 is inserted into the through hole 151, and a lid member 20, which is formed by sewing an injection member 200 at the center, is attached to the upper side of the enclosure 10, The upper surface of the cover member 20 and the end surface of the cover member 20 are sewn.

[Step of sewing the bottom member] ----- S9

8, a closed bottom member 30 is sewed to the bottom of the outer shell 10 to sew the floor of the outer shell 10 and the end of the bottom of the bottom member 30, In the case of the conventional container bag, a separate outlet is formed in the bottom member. However, the present invention allows the bottom member 20 to be hermetically sealed due to the characteristics of the contents to be received.

The present invention, which has been manufactured through all of the steps described above, can be shaped as shown in FIG. 9, but such a shape can be modified in various ways, and the hooking member 170 is inserted into the through- It is.

The container bag of the present invention manufactured as described above is limited to being used for transporting large quantities of heavy or heavy contents such as refractories to land and sea, Unlike bags, it should be manufactured so that it is made to be relatively more rigid and able to withstand the weight, so that the four sides of the outer sheath are integrally weaved, and then the fabric is provided in a specific region, So that it can be manufactured by the above-mentioned progressive manufacturing method which is different from the conventional container bag as it is made rigid so as to prevent the contents from being discharged.
