There is disclosed an aseptic flexible walled container having a rigid fitment member cooperative with an aseptic filling apparatus and including a neck, outer flanges surrounding the neck, a frangible membrane and an outer end rim receptive of an hermetically sealed lid. The neck is formed with an internal chamferred seating shoulder for fluid-tight engagement with a fill tube. One outer flange cooperates with clamping jaws of the aseptic filling apparatus for detachably sealing the fitment to a sterilizing chamber and placing it in position for insertion of the filling tube which ruptures the membrane and permits the aseptic introduction of product to the container\s interior. The other outer flange is secured to an opening in a wall of the flexible container. The joined fitment and container are presterilized prior to filling. Selected materials for the multi-ply container walls and the fitment permit the container to withstand gamma ray and other sterilization treatment, heat and pressure while maintaining required strength. After the container is aseptically filled, such as with flowable food product, the fill tube is withdrawn and a lid is hermetically sealed onto the rim of the fitment. A heat shield adjacent a container wall surrounds the fitment to protect the container from excessive heat generated by the associated filling apparatus during filling.
