<P>PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a packaging container which allows refilling of a content into another container easily, and can be disposed easily. <P>SOLUTION: First, a funnel 508 part having a funnel 520 and a sidewall 523 is inserted into an open end of a cylindrical container body 510. Subsequently, coils 554a and 554b are arranged by providing a predetermined gap between an overlapping portion of the sidewall 523 of the funnel part 508 and the sidewall 517 of the container body 510. Dielectric heating of a metal layer which structures the sidewall 517 is conducted by supplying a high-frequency electric current from a power-supply apparatus which is not shown in the figure, to the coils 554a and 554b for a predetermined time. A thermoplastic resin layer provided at the inner side of the metal layer undergoes melt-solidification, and thus the funnel part 508 is deposited to the container body 510. <P>COPYRIGHT: (C)2010,JPO&INPIT |
