a valve moveable from a closed position blocking flow from both the first and second dispensing paths and through the dispensing aperture and isolating the first and second liquids upstream of the valve to an open position permitting flow through both the first and second dispensing paths and the dispensing aperture to dispense the first and second liquids from the container; and

wherein each of the first and second enclosed bodies includes a neck and a downwardly extending ramp surrounding the neck, and wherein each of the first and second arcuate flanges of the common cap has a distal portion including an inwardly extending ramp configured to couple to the ramp of a respective one of the first and second enclosed bodies.

9. A container for isolating a first liquid and a second liquid prior to dispensing, the container comprising:

a first enclosed body for containing the first liquid and having a first body access opening;

a second enclosed body for containing the second liquid and having a second body access opening, the second body access opening being adjacent to the first body access opening;

a common cap including first and second arcuate flanges configured to couple the common cap to the first and second bodies, respectively, the common cap having a dispensing aperture;

an insert positioned between the access openings of the first and second bodies and the common cap, the insert including a first dispensing opening and a first tubular member around the first dispensing opening, a second dispensing opening and a second tubular member around the second dispensing opening, a first arcuate flange positioned at least in part around the first tubular member and opposite the first flange of the common cap and configured to couple the insert to the first enclosed body, and a second arcuate flange positioned at least in part around the second tubular member and opposite the second flange of the common cap and configured to couple the insert to the second enclosed body, the first and second tubular members and the first and second dispensing openings of the insert defining first and second dispensing paths each having an upstream entrance in fluid communication with the first and second body access openings and a downstream exit in fluid communication with the dispensing aperture; and

a valve moveable from a closed position blocking flow from both the first and second dispensing paths and through the dispensing aperture and isolating the first and second liquids upstream of the valve to an open position permitting flow through both the first and second dispensing paths and the dispensing aperture to dispense the first and second liquids from the container;

wherein each of the first and second arcuate flanges of the insert is shorter than each of the first and second arcuate flanges of the common cap.

10. The container of claim 9 , wherein the insert includes an upwardly projecting valve seat surrounding the dispensing aperture.

11. The container of claim 10 , wherein the valve is a flexible valve received in the valve seat.
