<p>A collapsible bag (10) for use in containing and dispensing a liquid, such as in a bag-in-box arrangement, and a method for making the bag. Prior to sealing together two bag walls (20, 22) to form the bag, a one-piece spout (26) and evacuation strip unit (24) is attached to the outside surface of one bag wall and one or more openings (40) are provided through the bag wall in liquid communication with a plurality of liquid channels (34) in the strip. The two bag walls (20, 22) are then sealed together to form the bag and the evacuation strip (24) provides liquid passageways for the liquid in the bag to flow to the spout (26) to achieve complete withdrawal of the liquid from the bag as the bag collapses.</p> |
