Abstract
A filling system for filling soup into gable top cartons is disclosed wherein the dripping of soup from the fill tube is substantially diminished by the present invention. The filling system includes a product tank, a knife-gate valve, a pump mechanism, a fill tube with a circumferential recessed area, and a sealing cone with a cutting edge. The cutting edge of the sealing cone prevents particulates from interfering with the sealing of the fill tube by the sealing cone. The knife-gate valve prevents the flow of product from the product tank during filling of a carton. The product tank may have an agitating means for evenly distributing the particulates throughout the soup.
