When welding,
The high-frequency induction heating means is used, and the welding protection by the ultrasonic vibration is used as the welding protection by the flange formed by melting and crushing the lower peripheral wall step portion of the opening surface with respect to the peripheral edge of the thin plate. . In this case, the high-frequency induction heating means heats only the thin aluminum foil of the barrier property, which is a conductor, and thus heats only the thin plate without heating and deforming the peripheral wall and the step of the pouring cylinder. Thus, the entire surface can be welded to the opening surface. Since high-frequency induction heating is instantaneous heat welding, unlike heat welding using a hot plate,
It is possible to reduce the influence of heat on the parts not to be welded. Therefore, this is a heating means that does not easily cause deformation of the molded article. Also, since the ultrasonic melting means generates heat of the thermoplastic resin itself, only the portion pressed by the ultrasonic melting device is heated and melted, and the lower peripheral wall step of the opening surface is crushed. The peripheral edge of the barrier thin plate is fused and protected at this portion. The lower peripheral wall step portion of this opening surface is easily melted and crushed by being pressed by an ultrasonic melting device to form a flange portion, so that the lower peripheral wall portion is heated and welded by a hot plate. No deformation due to heat.

て容易に効率よく製造することができる。The spout with a seat plate for a paper container manufactured by the method of the present invention has a barrier property in which a synthetic resin film is laminated or coated on an aluminum foil on the lower surface of an opening surface having a thin line for opening. Since the thin plate with the sheet is entirely welded by the high-frequency induction heating means, and its peripheral edge is welded and protected so that the lower peripheral wall of the opening surface is sandwiched by the flange formed by ultrasonic vibration. The gas generated in the container can block the permeation of gas, water vapor, etc. from the thin line portion, and can obtain the fragrance retention of the contents with high aroma, especially for the contents such as sake and vinegar. Even so, by preventing penetration from the peripheral edge of the thin plate, corrosion of the aluminum foil in the thin plate can be prevented, and the barrier property can be maintained. Moreover, since the welding to the opening surface of the thin plate having the barrier property is performed by the high-frequency induction heating means, the entire surface is easily welded, and the heating is instantaneous. Without applying, the peripheral edge of the thin plate is melted and crushed by ultrasonic vibration to form a flange by lowering the lower peripheral wall of the opening surface. There is no deformation. Therefore, it has good barrier properties,
In addition, a spout with a seat plate for a paper container, which is easy to open, can be easily and efficiently manufactured with high precision.
