Abstract
A collapsible container having at least two opposed flexible walls, an opening through which liquid can be removed, and a flange around the opening. The inner surface of each of the two sidewalls and the internal surface of the spout flange preferably have depressions and raised areas between the depressions. Typically, the depressions are not continuous and the raised areas are continuous. The depressions of one wall or flange cooperate with the depressions on the opposed wall to form liquid flow pathways when the wall or flange contacts the opposed wall. The liquid flow pathways allow liquid to pass therethrough instead of being blocked by the contact between a wall or flange and the opposed wall. A method of use and a method of making the bag are also disclosed.
