Abstract: A flexible container includes a panel structure of flexible web material, including panels that are adjoined to define a pouch. The pouch has a top opening with a fitment, and is expandable from a collapsed, unfilled condition to an expanded, filled condition. When the pouch is in the filled condition and resting on a flat surface, the panel structure supports the pouch in an upright orientation in which the fitment opening faces upward. The panel structure also provides the pouch with a flat footprint upon which the pouch overlies the flat surface. The flat footprint is defined in part by the pouch and in part by the lower handgrip in a condition folded beneath the pouch.
