Abstract: A filling tube for use in a container filling machine in which the tube is vertically disposed within a container as the container is being filled with a liquid. The lower end of the tube is adapted for insertion downwardly into the container and the upper end of the tube is provided with means for attachment to the filling machine. The lower end of the tube has an externally threaded portion with a pair of annular sealing portions, one sealing portion on either side of the threaded portion. A protective end tip member formed of a soft, low moisture absorbent material is secured to the lower end of the tube. The soft tip member minimizes damage to glass containers as the filling tube is inserted into the container. The tip member has an internally threaded portion which engages the externally threaded portion of the tube to secure the tip to the tube.

Abstract: A vent tube for a container filling machine in which the fill height is adjusted by the replacement of a removable lower tip. The vent tube has an upper tubular body with an interior axial passage through which gas is vented. The removable tip is attached to the body by insertion into a socket formed in the lower end of the passage. The tip is a tubular member with a wall surrounding an interior axial passage which communicates with the passage of the tube body. An opening is provided through the wall of the tip at the level of the predetermined fill height. Locking means are provided by which the tip is removably held within the socket of the tube body.
