发明名称 Plural-chambered dispensing device exhibiting constant proportional co-dispensing and method for making same
摘要 A plural-chambered, gravity-activated dispensing device that incrementally dispenses two or more flowable products at a substantially constant, predetermined ratio. In one preferred embodiment of the present invention, an inner container is positioned within an outer container, each container defining a chamber adapted to contain a flowable product, and having a discharge opening therein. An empty third container is sized and positioned within the inner container to impose on the inner chamber's pouring characteristics an effect similar to that imposed on the outer chamber's pouring characteristics by the inner container to thereby achieve a substantially constant dispensing ratio between the pourable products dispensed therefrom. In another particularly preferred embodiment, the effect of the third empty container mentioned above is superimposed on the inner container's shape and position within the outer container, thereby eliminating the third empty container. Also provided are a unique pouring spout and sealing cap to be used in conjunction with dual-chambered dispensing devices of the present invention, as well as a method of making such dispensing devices.
