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.

A nozzle suitable for filling a flowable viscous material into a container, comprising a tubular body defined by an outer body wall, within the body there being a plurality of longitudinal channels for the longitudinal flow of the viscous flowable materials along with the nozzle, the longitudinal channels comprising: a central channel, bounded by a central channel wall, one or more first side channels, situated between the central channel wall and the outer wall, the first side channels having a cross section perpendicular to the longitudinal axis of the tubular body which narrows in the direction from the outer body wall towards the central channel, and, one or more second side channels, situated between the central channel wall and the outer body wall, the second side channels having a cross section perpendicular to the longitudinal axis of the tubular body which does not narrow in the direction from the outer body wall towards the central channel, all of the longitudinal channels being open at an outlet end of the nozzle.
