CONSTITUTION: A container(100) is formed which has an envelope shape as a front face of the film(110) and a back face of film(120) meet. A foldable and expandable bottom folding portion(130) of standing type is formed on the bottom between the front face and the back face of film. A top folding portion(140) folded by the same extension is formed on a certain upper region of the front face of the film. An unsealed portion(150) is formed which extends to a predetermined length above from the top folding portion. Both sides of the front and back face of the film having the top and bottom folding portions and, selectively, the bottom end are sealed as a sealed portion(170,180).
