2. Description of the Related Art Recently, technological improvements in synthetic resin films such as polyethylene have been advanced and chemical resistance has been improved, and containers for storing various chemicals, foods, etc. have been manufactured using the films. . As a small-sized synthetic resin film (for example, polyethylene) bag-shaped container, 5 to 20
A liter capacity has been developed. As one of them, there has been proposed one in which a bag-shaped container is housed in a cardboard box and a cap is opened / closed in this state so that the contained liquid or the like can be used at any time.

This type of closed container is made of a synthetic resin film and is soft, and since it contains a liquid material, it does not retain its shape. Therefore, the use of the liquid material reduces the volume of the container. Even so, the advantage is that the outer corrugated cardboard box can be used as it is and is very convenient, and it has begun to spread in the technical field using various liquid materials. However, this type of closed container is difficult to hold by hand when taking out the contents from the cardboard box, and for this reason, there is a method of equipping one side edge of the container body with a gripping pipe or other members. Although it has been adopted, there are problems that it is difficult to manufacture and the gripped state is difficult to stabilize.

Therefore, the present inventor has proposed, as a closed container of this type, Japanese Patent Application No.
-240590 proposed a new closed container.
As shown in FIG. 8, this closed container constitutes a container body 1 by sealing a synthetic resin film 1a,
