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.

A container assembly for holding a mixture of at least first and second different liquids mixed in a predetermined ratio and for enabling additional quantities of said liquids to be added to said mixture in the same ratio, said container assembly comprising an outer container having a closed lower end and having an upper end with a fill opening therein, said outer container having an upright side wall extending between said upper and lower ends, said outer container being partially filled to a first level with said mixture, an inner container disposed within said outer container and having a closed lower end and an open upper end, the entirety of said inner container being spaced inwardly from said side wall of said outer container whereby said inner container coacts with said side wall to define an annular chamber which completely surrounds said inner container, the volume of said inner container being substantially less than the volume of said outer container, a fixed orifice in the lower end portion of said inner container and enabling the mixture of said chamber to flow into said inner container and to fill said inner container to said first level, the open upper end of said inner container communicating with said fill opening to enable an additional quantity of said first liquid to be introduced into said inner container via said fill opening, the cross-sectional area of said inner container being substantially greater than the cross-sectional area of said orifice whereby said first liquid may be introduced into said inner container to a second level higher than said first level, an additional quantity of said second liquid being introduced into said container assembly by way of said fill opening and at least partially by way of the open upper end of said inner container whereby said second liquid intermixes with said first liquid to fill said container assembly to a level higher than said first level with a mixture of said predetermined ratio, a nozzle holder in the upper end portion of said inner container and adapted to support a filling nozzle with an automatic shut-off, said nozzle holder telescopically receiving said nozzle and having means for limiting insertion of said nozzle into said inner container, and an opening in said nozzle holder and establishing direct communication between said nozzle holder and said outer container to enable automatic shut-off of said nozzle when liquid reaches the level of said opening.
