Abstract
The invention provides a dispenser for dispensing one or two liquids simultaneously. For two liquids the dispenser has a pair of inverted containers defining bottom openings with the containers arranged in side-by-side relationship. A base is sealingly attached to the containers and has two reservoirs and associated dispensing openings. The arrangement is such that liquid from the containers will pool in the reservoirs below the dispensing outlets creating a condition of equilibrium in the containers. When the user disturbs the equilibrium, liquids from both containers flow out through the respective dispensing outlets for mixing in use, and then after dispensing air, flows into the dispenser to replace dispensed liquid thereby allowing equilibrium to again be established. When the invention is used for dispensing a single liquid, one container contains liquid and the second container is squeezed to disturb the equilibrium and cause dispensing.
