Provided is a bag with which the task of filling a bottle with liquid can be performed in a short time while preventing a pour spout from being blocked. A pour spout of a bag has a pair of pour spout seals that face each other across a boundary that is a bisector line bisecting the pour spout along the direction of pouring. The pair of pour spout seals includes a pair of first sealing portions that extend from a portion to be opened toward a main portion and a pair of second sealing portions positioned between the pair of first sealing portions and the main portion. The first sealing portion and the second sealing portion are configured such that a length L1 ≤ 9 mm, an angle α ≥ 30°, and the angle α < an angle β, where L1 is the length of the first sealing portion in the direction along the bisector, α is the angle formed by the inner edge of one of the pair of first sealing portions and the inner edge of the other of the pair of first sealing portions, and β is the angle formed by the inner edge of one of the pair of second sealing portions and the inner edge of the other of the pair of second sealing portions. |
