ABSTRACT:
A bag has a bag body made of two sheets and sealed throughout the periphery except at one place. A flattened, cylindrical inlet-outlet spout is connected at a base end thereof to the one place and extends at another end outwardly of the bag body. A pocket disposed on the bag body at the base end of the inlet-outlet spout, and is adapted to receive the inlet-outlet spout in an axially folded state. This bag is simple in construction and yet capable of reliably preventing leakage of contents.
