Abstract

A device for dispensing a striped mixture of two components of a paste-like flowable substance includes a lower container in which one of the components is retained. A dosing unit mounted on the container, includes a pushbutton which is depressed for forcing the first component from the container through a set of valves into a compartment of the dosing unit, through a centrally located tubular element within the compartment, and out of an upper outlet for dispensement from the device. The interior of the compartment between the tubular element is filled with a second component, which is forced upward by the first component entering the compartment, and into the tubular element via openings therethrough, for mixing with the first component as it moves through the tubular element and out of the outlet, for dispensing a striped mixture of the first and second components. The combination of the compartment and tubular element are replaceable as a module on the dosing unit, for selectively providing different second components for striping with the first component.
