    Patent number: 6158195
    Abstract: A fill system for use in a packaging machine is disclosed for filling a container with a primary and a secondary product. The fill system includes a primary pump system for pumping a predetermined amount of the primary product received at an inlet thereof. A primary fill pipe having an outlet overlying a container processing path along which the containers are filled and sealed by the packaging machine is connected to receive the predetermined amount of primary product from the outlet of the primary pump system. The fill system further includes a secondary pump system for pumping a predetermined amount of the secondary product received at an inlet thereof to an outlet thereof. A secondary fill pipe is connected to receive the predetermined amount of secondary product from the outlet of the secondary pump means.
