PROBLEM TO BE SOLVED: To provide a pouch container for food and drinks, sealability of which can be secured without needing large-scale and expensive equipment, and residual air of which is caused to approach zero sufficiently and stably.SOLUTION: A pouch container 12 is supported so that its opening is positioned upward. Next, using a pair of deaerating members 6 in which a vertically communicating ventilation groove is formed, a side face of the pouch container 12, which is a section above the liquid level of a fluid accommodated in the pouch container 12, is held from the outside of the pouch container 12. Then, using a pair of liquid level raising members 7, a side face of the pouch container 12, which is a section below the liquid level of the fluid, is held from the outside of the pouch container 12. Thereby, residual air inside the pouch container 12 is guided upward through the ventilation groove of the deaerating members 6, and the fluid is raised to the height between a seal portion of the pouch container 12 and the deaerating members 6. Finally, the pouch contain 12 is sealed by the seal portion. |
