Abstract: Dispenser for dispensing simultaneously two liquids held in respective flexible containers, one within the other. Concentric tubular passages are provided for flows of the liquids from their containers when pressure is applied to the outer container. The inner passage has a narrow elonage form and terminates within the outer passage a final exit section of which provides a common conduit for both flows. A reduced liquid pressure is produced at the inner passage termination by having a tapered upstream end of the conduit overlapping the termination and the conduit is configured to inhibit mixing of the flows along its length. The two liquids are thus dispensed in a single stream in which, e.g., a colored flow from the inner passage is visible in the core of the stream. By adjusting the position of the conduit taper relative to the inner passage termination, it is possible to vary the proportions of the two components in the flow.
