    Publication number: 20100107568
    Abstract: A heat welding member 23 of a seal head 21 formed in the shape of a flange portion 11a of a container 10 is heated by high frequency induction heating and a cap 12 is welded by pressing the heated seal head 21. By using the seal head 21 comprising the heat welding member 23 having a shape necessary for sealing the cap 12, influences by temperature drop and inflation of gas in a head space can be prevented and sealing at a high speed and in a stable manner can be achieved.
