Abstract
A method and apparatus for maintaining the proper shape and orientation of a carton with respect to a fill pipe of a liquid packaging machine during a liquid-filling operation. The apparatus, internal carton guides attached to a fill pipe, are elongated fin-shaped members which are adapted to engage opposite corners of a carton. The internal container guides include tapered lowered edges which gradually direct the corners of the carton to the outermost edges of the guides. The uppermost edges of the internal container guides include stop members which serve to engage the top edge of the container and inhibit any further upward movement. The internal container guides securely maintain the container in a stable and properly-oriented position throughout the liquid-filling operation.
