<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a hermetic container in which the laser beam irradiation energy to be supplied for welding a welding-scheduled part is reduced in a necessary minimum manner; the deterioration of the quality of the hermetic container such as leakage of a content, lid opening, and partial cloudy turbidity is suppressed, and further suppressing the decrease of the quality such as deterioration and degeneration of a content by consistently welding the welding-scheduled part even when the ambient temperature is changed. <P>SOLUTION: The method for manufacturing the hermetic container for welding a container barrel filled with a content to a lid fitted to a mouth part of the container barrel in an airtight manner by the laser beam welding method comprises an arrangement step of placing the container barrel in a laser beam irradiation area while the heated lid is placed on the mouth part of the container barrel, and a welding step of sealing the container by irradiating laser beams to the welding-scheduled part of the lid to the container barrel to weld the lid to the container barrel. <P>COPYRIGHT: (C)2008,JPO&INPIT |
