A primary panel (10) is provided for cooperation with a liquid filled flexible packaging bag during withdrawal intermittently of the contents thereof. The primary panel has at least an operatively foward zone (9) adapted for attachment to a base (3), generally the bottom of a box (1), in a relatively fixed position with respect to the base. A normally inclined zone (10) attached to the forward zone is adapted to flex between a position in which it is generally parallel to the base under conditions corresponding to a full flexible packaging bag and positions in which it is inclined relative to the base under conditions corresponding to a partially filled or substantially empty flexible packaging bag. The inclined zone is resiliently biased relative to the forward zone towards said inclined position. Preferably a pinch panel (19) is provided on a lid (2) to the box and the two panels are arranged to squeeze a liquid filled flexible packaging bag positioned between them during withdrawal of the contents thereof in a progressive manner.
