Abstract

Disclosed is a bag adapted for lining the inside of a container, comprising side walls and a closed end wall comprised of a flexible synthetic resinous sheet material and an open end wall opposite to the closed end wall, wherein the inside circumference of the bag defined by the side walls becomes increasingly larger from an intermediate point on the side walls in the direction of the open end wall, while the outside circumference preferably remains substantially constant.
