The bag further comprises expansion suppression means 30 disposed on an area where the liquid passes when the liquid moves from the storage part to the pouring mouth part, on the main body part. The expansion suppression means has a belt piece 31 which is thermally deposited to inner faces of the front face film and rear face film. The belt piece is divided into a first part 32 which is thermally deposited to the inner face of the front face film, a second part which is thermally deposited to the inner face of the rear face film, and a folding part between the first part and the second part.SELECTED DRAWING: Figure 1 |
