A method for washing a flexible container for liquid transport made of an air tight, water resistant sheet material, the flexible container including a top face portion, a bottom face portion, and a peripheral face portion connecting the top face portion and bottom face portion, and having an air tight, water resistant slide fastener mounted to the peripheral face portion with an exception of a non-opening and closing portion,

• the washing method including:
• opening the air tight, water resistant slide fastener;
• suspending the container to spread out and open a lower part of the peripheral face portion in a direction in which the top face portion and the bottom face portion are separated from each other as being fanned out about an upper basic point at the non-opening and closing portion of the peripheral face portion so that an inner face of the container is exposed to outside;
• and
• drying the flexible container, after washing or sterilizing treatment.

A method for washing a flexible container for liquid transport made of an air tight, water resistant sheet material, the flexible container including a top face portion, a bottom face portion and a peripheral face portion connecting the top face portion and bottom face portion and comprising a liquid stirring port having air evacuating means in accordance with an internal pressure and formed at the top face portion, an openable/closable liquid injecting and ejecting port formed on the peripheral face portion in the vicinity of the bottom face portion, and an air tight, water resistant slide fastener mounted to the peripheral face portion with an exception of a non-opening and closing portion,

• said washing method including:
• closing the air tight, water resistant slide fastener while the container is empty;
• forming the container to be in its swelled state;
• opening the liquid stirring port, and then, jetting washing liquid toward an internal wall of the flexible container via the stirring port;
