Abstract
This invention relates to a novel, multisegmented nozzle for dispensing viscous materials, particularly for dispensing differently colored toothpaste into toothpaste tubes so as to produce toothpaste of striped appearance when dispensed from the tube. The nozzle has a tubular body defined by an outer body wall, and has within the tubular body a central channel and a plurality of longitudinal first and second side channels situated around the central channel. The first side channels have a cross section which narrows towards the central channel; the second side channels have a rectangular cross section. Because of this configuration the nozzle is able to load multicolored toothpaste tubes which dispense toothpaste in a substantially more uniform striped pattern than conventionally loaded multicolored toothpaste tubes.
