2068332 9108979 PCTABS00005 The invention relates to a container for successively dispensing substantially uniform volumes of a plurality of liquid ingredients such that the liquids are simultaneously dispensed in a desired proportion to form a mixture. The problem associated with tiltable trap chamber dispensers is their inability to proportionally dispense different liquids without cross contamination. The container has a plurality of separate compartments (12); each compartment (12) being adapted to house a different liquid ingredient. Each compartment has a tubular metering device (10) located therein. The metering device dispenses a previously metered volume and meters a second volume by controlling the venting of air within the compartment each time the container is tilted and uprighted as in a normal dispensing operation. A continuous lip (23) surrounds the dispensing opening of each metering device. The continuous lip (23) prevents a liquid ingredient from entering the dispensing opening of another liquid ingredient compartment (12) and contaminating that compartment.
