  The flexible packaging bags described in the prior art have the advantage of being easy to handle and environmentally friendly, but have the disadvantage of not being self-supporting. Therefore, if there is no spout with a cap, it is necessary to transfer the liquid remaining after opening to another container, and even if there is a spout with a cap, it takes up space. Exceptionally, the stand pack is self-supporting, but it also loses self-supporting when the liquid content decreases. Therefore, even if a flexible packaging bag has a cap, there is a problem that it is difficult to use for a purpose of putting a liquid such as soy sauce or dressing to be dispensed on a table.
