PROBLEM TO BE SOLVED: To provide a simply structured pouch container whose spout device excellently retains the attitude.SOLUTION: The pouch container is structured such that a spout device 2 is mounted at the top end of a bag body 1. The bag body 1 formed from front and back sheets 3 and 4, and a bottom sheet 5 has self-supporting characteristic. Elongated reinforcement bodies 12 extending downward from under the spout device 2 is welded on the inside surface of the front and back sheets 3, 4. The body 1 swells more toward the bottom when a content is filled and the bending force to the outside force in the front and back direction increases toward the bottom. Because the body 12 stands up from a lower position where the bag body 1 is more rigid (has a stronger shape-keeping characteristic) even though it is provided only at an intermediate part in the lateral direction of the bag body 1, it exhibits a high reinforcement function. The body 12 is not bothersome when a person holds the bag body 1. |
