发明名称 Multi-component striping paste dispenser
摘要 A dispenser for dispensing striped paste-like materials, e.g. toothpaste. The dispenser includes a striping assembly including a shoulder member having a central opening, preferably with a threaded neck portion, and a barrier member having a central opening and adapted to be located within the neck portion of the shoulder member. A tubular nozzle with a plurality of radial openings therein is located between the shoulder member and the barrier member to provide a striped effect upon extruding a paste-like material through the assembly. Forcing the paste-like materials from the dispenser can be effected, for example, by squeezing a collapsible tube attached to the striping assembly.
