A liquid container comprises a liquid container pouch of flexible sheets and a liquid outlet between the pair of flexible sheets to permit extraction of a liquid in the pouch. The pouch includes a pair of side portions and a lower gusseted portion defining a basal gusset and including bilateral edge portions overlapping individual lower border zones on the side constituting the lower borders of the pair of side portions during extraction of liquid. The individual lower border zones and the individual bilateral side edge portions overlap to define sealed portions; the lower gusseted portion has a fold line parallel to the lower border between the bilateral edge portions and is oriented in a folding direction to define a chevron shape pointing inwardly into the pouch; and the two sealed portions having regulators to restrain outward expansion by a greater extent than other faces on the pair of side portions.
