The invention relates to a process and apparatus for aseptic filling of pre-sterilized non-rigid containers, especially foodstuffs containers. The said process involves taking laying hold of the container by means of air-suction, followed by sterilization of part of the container and the means holding same, then piercing of the actual container and subsequent introduction thereinto of sterile gas. This is followed by introduction of the foodstuff into the container and ultimate hermetical heat-sealing of the container thus filled. The apparatus used for carrying out the process comprises a movable workhead, positioned appropriately along a traverse overlying the conveyor bringing up containers for filling the workhead has means for taking hold of the container by suction, means for piercing the container, and for introducing sterile gas and foodstuff into the container. The workhead carries out such operations by moving into angularly distinct respective working postures. A series of movers in the apparatus provide for displacement of the workhead itself and of its individual parts. The apparatus also has feeder means for supply of foodstuff, sterile gas and sterilizer fluid, and means for controlling the start and finish of the individual stages, and regulating the operation thereof.

A process for aseptic filling of pre-sterilized, non-rigid containers comprising attaching a workhead to the outer surface of a small portion of the container, sterilizing the outer surface of the small portion and the attached parts of the workhead, piercing the small portion of the container, introducing sterile gas into the container through the pierced portion, introducing a feeder tube through the pierced portion, introducing foodstuff into the container through the feeder tube while permitting sterile gas to be expelled from the container through the pierced portion, terminating the flow of foodstuff into the container, withdrawing the feeder tube, hermetically sealing the container, separating the workhead from the container, and cleaning the workhead.
