An object of the present invention is to provide a bag which enables refilling of a container from the bag to be carried out smoothly, without the contents coming out of the pouring mouth all at once and without the bag losing its shape, and the pouring mouth to be set to a certain specific size; which eliminates the need of a special sealing device; and which is strong. Further, with the bag according to the invention, the refilling can be carried out easily, without scissors or the like being required for forming the pouring mouth, the overall shape of the bag does not have to be made long in the vertical direction; and without any of the contents remaining in the bag during pouring. In the bag of the present invention, heat sealed parts 5 and 6 are formed at the right and left side edges and the bottom is closed up; at the top, an upper heat sealed part 8 is formed along the upper edge portion, and an inclined heat sealed part 9 is formed diagonally to extend from the upper heat sealed part 8 to one of the left and right side heat sealed parts 5 and 6; when the bag is opened by ripping along the upper edge portion from a notch 10, the upper heat sealed part 8 is ripped away, and part of the inclined heat sealed part 9 remains behind on the main part of the bag.
