ABSTRACT:
An area where a liquid substance, for instance, is present inside a bag, that is, the area where the liquid substance adheres to the inner surface of the bag, is ultrasonically sealed (thus forming an ultrasonically sealed area), and then an area that is separated from the ultrasonically sealed area by a predetermined distance toward the edge of the mouth of the bag is heat-sealed (thus forming a heat-sealed area), so that the a portion of the liquid substance, that is separated and is present above the ultrasonically sealed area, is sealed inside the space between the two sealed areas.
