Abstract
A method and apparatus for accurately discharging the entire contents of a container is disclosed. A rigid container has an open upper end and at least one hole in the bottom of the container. The container has a flexible liner with a neck portion which is folded back around the upper end of the container to form a cuff. The cuff is sealed against the sides of the container and the container is inverted. A gas is injected through the hole or holes in the bottom of the container into the space between the flexible liner and the container. This everts the liner and insures that all of the contents of the container are dispensed.
