<p>Method and apparatus are disclosed for filling open-top containers with material capable of flowing such as liquid while preventing contamination of the container exteriors by liquid overflow. The containers are advanced along a predetermined path. The liquid is discharged towards the open tops of the containers to be filled in a substantially continuous sheet, descending adjacent the predetermined path. The containers are advanced beneath the liquid sheet with the containers tilted at a predetermined angle to the vertical. The tilted containers are overfilled and the overflowing liquid leaves the tops of the containers generally at the tilted lower top portions thereof. Streams of air are directed towards the tilted containers below the open tops thereof to cause the air to pass around the peripheries of the containers adjacent the container tops. The air flow prevents the liquid from escaping the open tops of the containers except substantially at the lower tilted top portions thereof, where the air flow causes overflowing liquid to be deflected away from the sides of the containers. The exterior of each container is thereby kept free of liquid.</p> |
