A method and system for aseptic filling of containers. The flexible containers (1) are presterilized and a rupturable membrane (41) covers the inlet to the container. The filling head (20) includes a recess (46) below the outlet valve (24) and this recess is closed by the rupturable membrane (41) when the container inlet is aligned with the filling head. After alignment sterilizing fluid is introduced into the recess to sterilize the outer surface of the membrane and the internal surfaces of the recess. Following sterilization the valve membrane (22) moves towards the rupturable membrane (41) allowing the piercing tool (25) to rupture said membrane. The outlet valve (24) of the filling head is opened and the liquid is allowed to flow into the container. Subsequent to completion of the filling cycle the inlet to the container is sealed and the sealed and filled container (1) is then removed from the filling head (20).

A method of aseptically filling containers through a container inlet from a filling dispenser comprising the steps of: (a) sterilizing sealed containers in which the container inlet has a heat sealable flap on one side of said inlet and is covered on the other side of said inlet by a rupturable closure; (b) maintaining the internal surfaces of the filling dispenser in a sterile state; (c) bringing the closed inlet of the container into abutment with the outlet nozzle of the filling dispenser by means of a movable container support; (d) introducing sterilizing fluid into the space between said nozzle and said closed inlet in a direction laterally of product flow from said outlet nozzle into said container inlet and withdrawing it laterally; (e) breaking said rupturable closure and filling said container; (f) closing said inlet by heat sealing said heat sealable flap to the interior side of said inlet; (g) introducing sterilizing fluid in to the space between said nozzle and said closed inlet in a direction lateral to product flow from said outlet nozzle in to said container inlet and withdrawing it laterally; (h) removing said container from said dispenser.
