PROBLEM TO BE SOLVED: To solve the problem that a container is hard to handle if the container suitable for storing very small objects is small, the size of the container must therefore be increased to some extent, the objects are not stable therein, or the checking range of the contents is also increased. SOLUTION: The folding bag is a flat bag of a vertically symmetric trapezoidal shape. Another bag to insert an opening part is further provided in a triangular portion of a bottom part. The folding bag is folded into halves after contents are stored, and the opening part symmetric to the bottom part is inserted in the bottom part. The folding bag is easily handled and sealability thereof is ensured though the size of the folding bag is small. COPYRIGHT: (C)2004,JPO&NCIPI
