Abstract:
A collapsible bag (100) for dispensing liquids which includes at least one sheet (104, 108) sealed to define an enclosure and a fitment (124) (spout) attached to the enclosure and out through which liquid in the enclosure is dispensed.

The bottom surface (246) of a lower flange (244) of the fitment may have concentric ridges (298) (or spirals) (256) and/or radial grooves (278). Also disclosed are methods of making the bag from one, two, three or four sheets.
