Thin film material 801 package. At the same time, the short side 903 (see FIG. 9 (c)) adjacent to the end portion 905 is packaged. As a result, a package portion 119 that holds the nozzle 120 is formed at the end portion 905, and a package portion 117 that packages the back edge portions 112 c and 113 c is formed at the end portion 903. Subsequently, as in the first embodiment, the short side 906 on the upper side of the film material 801 is expanded to both sides, openings are provided (see FIG. 9 (d)), and the contents are filled from the openings.

Then, in the short side 906, the front and back surfaces of the thin film material 801 are respectively folded in half (see FIG. 9 (e)), and the upper short side 906, the corresponding surface, and the heat sealing are separately packaged. . Thereby, the package parts 115 and 116 are formed (see FIG. 1) (see FIG. 9 (f)).

As described above, a packaging container 800 with a nozzle as shown in FIG. 8 is completed.

A method of using the packaging container 800 with a nozzle is the same as the setting method of the specific embodiment 1 (see FIG. 4 and FIG. 5), and a description thereof is omitted.

The packaging container 800 with a nozzle according to Embodiment 3 can also achieve the same effects as the packaging container 100 with a nozzle according to Embodiment 1 described above.
