ABSTRACT:
An apparatus for liquid filling a flexible collapsible container in the form of a plastic pouch for packaging wine is disclosed. The pouch has a pouring spout and a closure for the spout. The apparatus comprises a base for firmly holding the spout and a frame movable relative to the spout. The frame supports a closure removal head and a liquid fill head, either of which may be brought into engagement with the spout upon movement of the frame. The closure removal head is adapted to grip the closure and, upon movement of the frame, remove the closure from the spout. The liquid fill head is adapted to apply a vacuum pump output to the spout to evacuate the pouch, apply liquid to fill the pouch and supply nitrogen to purge contaminants from the pouch. All operations are performed without the need to move the pouch.
