PROBLEM TO BE SOLVED: To provide a container to be manufactured by minimizing as far as possible the quantity of scrap cut pieces as industrial wastes generated out of an inflation tube, easily recognizable in use and scarcely generating errors in use. SOLUTION: The bag-shaped container 1 is formed by heat sealing at least a given position in the width direction of the inflation tube 2 composed of a flexible plastic formed continuously into a cylindrical shape and cutting off a heat sealing zone 3 in the width direction to form an upper section and a bottom section of the container separated each other, and the heat sealing zone 3 on the bottom side of the container 1 is formed into an almost recessed shape having a recess facing downward, and the recess is left as it is as an unsealed section 7. |
