Using a laser device, semi-cutting cut lines a, a for cutting the pouring line 22 on the front and back of the pouring line 22 of the flexible packaging bag 20 made of a laminated resin film, and the cutting line a The two half-cut lines b, b, b, b each having a length of 15 mm orthogonal to a and a are cut into the base film layer 2 and the barrier film layer 3 so that the sealant layer 4 is not cut. And at the same time, shampoo and rinse 550 ml from the upper filling port d. To capacity. Then, the filling port d is heat-sealed to form a bottom folding seal commonly referred to as a standing pouch having a bottom width, a width and a height of 62 × 124 × 200 mm as shown in FIGS. A flexible packaging bag 20 of this example of a formula was produced.
[0020]
Subsequently, the intended cutting line a of the pouring line 22 of the flexible packaging bag 20 of this embodiment is cut by pulling with a finger, the spout 24 is opened, and the flexible packaging bag 20 is overturned and hung. However, as shown in FIG. 2 (A), the uncut sealant layer 4 is stretched by the impact of pulling and cutting with a finger and by the momentum of the liquid content to be poured first. In order for the two half-cut lines b, b, b, b on the front and back sides to open appropriately, the spout port 24 of the spouting pipe line 22 is greatly opened to form a regular plastic bottle with a pump. You can easily refill housed shampoos and rinses. Also, when the amount of the liquid contents decreases, even if the portion of the spouting channel 22 of the flexible packaging bag 20 becomes wrinkled due to the recoil of the bulge of the portion near the spouting channel 22 of the large body portion. As shown in FIG. 2 (B), once the stretched sealant layer 4 becomes wrinkled, and the half-cut lines b, b, b, b are not completely closed, the spout 24 is largely opened. The shampoo and the rinsing containing the last one drop can be poured out without softening the spout 24 of the pouring line 22 although the size is reduced. A bag 20 was obtained.
