- the fiber spring part 46 of both side parts 20 C protrudes outside the body part 20 (Fig. 2 ( ⁇ )) and the one that folds inside the body part 20 (Fig. 2 ( ⁇ )).
- the self-standing bag 10 with the ⁇ -line portion 46 protruding outward has a smaller overall thickness in the folded state.
- the self-supporting bag 10 is suitable for use as a self-supporting bag which is a product containing a content agent containing at least one of 0.1% to 50% of a surfactant or 0.1% to 50% of a solvent.
- the self-supporting bag 10 is manufactured in a manufacturing line as schematically shown in FIG.
- Synthetic resin bag body 11 can be manufactured by direct molding.
- direct blow molding a parison is extruded into a mold, and is stretched in the circumferential direction by blowing air into the parison to form a bag body 11.
- Direct blow molding forms a bag body 11 composed of a single layer or a laminated resin layer.
- the resin material of the bag body 11 by direct blow molding is LD PE (low density) when it is a single layer.
- the outer layer may be HDPE and the inner layer may be LDPE or L-LDPE. It is also possible to adopt a structure in which the layer is HDPE and the outer layer is LDPE.
- the molded bag main body 11 has a tubular neck portion 12 having an air blowing opening 12 A at the tip thereof, which is connected to an upper portion of the filling port forming portion 22 described above.
- a vacuum suction tool 51 is inserted into the air blowing opening 1 2 A of the molded bag body 11, the internal pressure of the bag body 11 is reduced, the volume of the bag body 11 is reduced, and the bag body 11 is folded.
- the folded form of the bag body 11 is, for example, as shown in FIG. 2 described above.
- the bag body 11 may be one that is pressed by application of an external force to reduce its volume and folded into a canine.
- the degree of decompression is checked by a pressure gauge or the like provided in the piping system of the nocuum suction tool 51, thereby performing a leak ashes of the bag main body 11.
- the base connected to the filling port forming portion 22 of the cylindrical neck portion 12 is heat-sealed with a heat seal tool 52 to form a seal portion 12B, and the seal portion 12B Cut the top iron.

Also, since the spout forming portion 24 is formed into a three-shape when the bag body 11 is blow-molded, it is difficult to close the spout.
- the bag body 11 Since the bag body 11 is not formed by laminating sheets, it is not necessary or necessary to form the bag body 11 with a laminated resin having an adhesive layer interposed. Therefore, the bag body 11 can be constituted by a single-layer flute, and the surfactant and the solvent can be used. It is possible to stabilize the quality of the bag without causing the content agent contained to penetrate into the adhesive layer of the layer film to cause peeling of the laminated resin.
- the body 20 and the bottom 30 of the bag body 1 1 are formed into a body, which is strong against the impact of falling and hard to crack.
- the spout forming portion 24 formed in the bag body 11 is in a range of 0 to 90 degrees, preferably 30 to 60 degrees with respect to the horizontal direction parallel to the bottom 30 of the bag body 11. Of these, it is best to incline at 45 degrees to make it easier to pour.
- the spout forming portion 24 formed in the bag body 11 can be designed to be formed so as to protrude outward from the bag body 11, the projecting stab dog can be freely configured. Bags that are easy to pour out can be easily manufactured, for example, by increasing the protruding length of the mouth or widening the spout.
- the self-standing bag of the present invention is not limited to blow molding, but may be injection molding or the like as long as it is formed by die molding.
