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 to an outlet 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 container processing path lies generally perpendicular to the primary fill pipe. A nozzle is connected at the outlet of the fill pipe. 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. The secondary fill pipe is concentrically disposed in the primary fill pipe and has an outlet that likewise overlies the container processing path. A valve mechanism is disposed, for example, concentrically within the secondary fill pipe and includes a sealing member positioned at the outlet of the secondary fill pipe. The sealing member is operable to control the flow of the secondary product from the secondary fill pipe. Operation of the fill system may be user controlled by a user interface and control system.
