ABSTRACT:
A fill tube has a hollow interior with a product inlet orifice, a product discharge orifice and a fill rod orifice connected to the interior. A plunger rod having ends is mounted through the fill rod orifice such that its first end is located within the hollow interior of the tube adjacent the product discharge orifice. The plunger rod has a valve member on this end that is tear drop in shape and is sized to fit into and seal against the inside of the discharge orifice. A plurality of fill tubes and plungers can be mounted on a packaging machine in conjunction with a prime mover and a moving member that is operated by the prime mover. Each of the plungers are connected to the moving member so as to be moved within their fill tubes in conjunction with movement of the moving member imparted thereto by the prime mover.
