A detent structure is provided to locate the sliding dam at pre-marked measurement locations. The detent structure is centrally located to permit strengthening of the sliding attachment means and reduce wear.

Abstract: A container assembly includes an outer container and at least one inner container whose internal volume has the same ratio to the remaining internal volume of the outer container as the desired ratio of liquids to be mixed. An orifice in the inner container establishes communication between the lower end portions of the two containers so that a previously mixed liquid mixture of a predetermined ratio resides at the same level in both containers. The container assembly may be filled with additional mixture of the same ratio by filling the inner container with one liquid and by flushing that liquid from the inner container and into the outer container with a second liquid until the outer container is full.
