Description of the Related Art In a carton container mainly made of paperboard for liquid packaging for packaging liquids for beverages such as sake and juice, a heat-sealing property of polyethylene resin or a blend resin of polyethylene resin and polyethylene terephthalate resin is used. When a plastic spout (spout) is provided, the spout is attached to the container in advance, and the spout is heated by ultrasonic welding means that is heated and welded by ultrasonic waves while pressing the attached spout toward the container side. There is a plug welding device for welding.

First, as shown in FIGS. 4A and 4B, a plug 3 is inserted into a plug mounting hole 2 formed in the upper end of the carton 1.
Is inserted from the inside of the carton 1 to the outside with the base 4 (flange) inside and the plug 5 (the cylindrical spout 5a and the cap 5b screwed into it) outside. Alternatively, as shown in FIG. 4C, the base 4 of the plug 3 is superimposed on the outer peripheral surface of the plug mounting hole 2 on the outer surface side of the carton 1 with the plug portion 5 facing outward.
