Abstract
A multi-component toothpaste pump dispenser utilizes a delivery tube extending below the reservoir of striping paste and into the reservoir of main paste. The delivery tube has holes at the juncture of the top of the tube and the top wall of the pump chamber to allow passage of the striping component while the main component flows axially through the tube. A valve closes all of the openings when the pump chamber reforms to incrementally advance a piston type follower.
