PROBLEM TO BE SOLVED: To shorten the time required for discharging the contents of an inner bag for a container by a method wherein impurities such as garbage or dust are prevented from getting into the inner bag so that the contents of the bag can be fed into and discharged from the bag surely and smoothly. SOLUTION: An inner package 1 for a container, which is placed in a container 20 having a takeout port at its lower part, comprises a closed bag body 2 made of a synthetic resin film, a hanging part 4 integrally formed to the top of the body 2, and a feed and discharge cylinder 6 which is integrally formed to the lower part of the bag body 2 so as to communicate with the body 2 and which has a flange 7 for engagement with the outer end of the takeout port. A coin spring 47 is fitted in the cylinder 6 and in the interior of the lower part of the bag body 2 to prevent crushing of the cylinder 6 and the lower part of the body 2.
