    • Means for dispensing simultaneously two liquids held in respective flexible containers (2,24), one within the other, comprise concentric tubular passages (16,38) for flows of the liquids from their containers when pressure is applied to the outer container. The inner passage has a narrow elongate 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 (52) of said conduit overlapping said 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 an, eg. coloured, flow from the inner passage is visible in the core of the stream. By adjusting the position of said conduit taper (52) relative to the inner passage termination it is possible to vary the proportions of the two components in the flow.
    • 用于同时分配保持在相应的柔性容器(2,24)中的两个液体的装置,一个在另一个容器中的装置包括同心的管状通道(16,38),用于当压力施加到外部容器时液体从其容器流动。 内部通道具有窄的细长形式并终止在外部通道内,其最终的出口部分为两个流动提供了共同的管道。 通过使所述导管的锥形上游端(52)与所述终端重叠,并且所述导管被配置成阻止所述流沿其长度的混合,在所述内部通道终端处产生降低的液体压力。 因此,这两种液体分配在单一流中,其中例如。 有色的,从内部通道的流动在流的核心中是可见的。 通过调节所述管道锥度(52)相对于内部通道终端的位置,可以改变流中的两个部件的比例。
