While being guided by means of a plurality of forming rings 15 disposed along the traveling direction, the vertically traveling packaging material 11 is formed into a tubular shape such that opposite side edges thereof overlap each other by a predetermined overlap quantity. A portion where the opposite side edges overlap each other; i.e., an overlap portion, is sealed in the longitudinal direction by means of an unillustrated longitudinal sealing device.
While the packaging material 11 is guided by means of a tube guide roller 17, liquid food is supplied from above to the tubular packaging material 11 via a filling pipe 16. Next, while being gripped from opposite sides by means of sealing jaw devices, the packaging material 11 is laterally sealed at predetermined longitudinal intervals and is formed into a pillow-like prototype container 18 through deformation effected by unillustrated forming flaps. The sealing jaw devices constitute a lateral sealing device.
Subsequently, each prototype container 18 undergoes cutting at a laterally sealed portion; i.e., a lateral seal portion, and folding along previously formed folding lines so as to be formed into a predetermined shape, thereby assuming the form of a brick-like packaging container which contains a predetermined amount of liquid food.
