ABSTRACT:
A high impact strength, flexible bag comprises a bag formed from spaced confronting walls of flexible sheet material joined together at the margins thereof to form a sealed enclosed space only partially filled with a liquid which is to be dispensed from the bag. There is immersed in the body of the liquid within the bag an open-cellular compressible body which extends throughout most of the liquid in the bag when the bag is lying on a horizontal support surface. The structure defining the open cells of the compressible body form such a substantial obstruction to the outward flow of liquid in the bag when a sudden external force is applied to the bag that the liquid therein cannot flow outward to rupture the bag walls.
