Abstract
An apparatus for the simultaneous dispensing of fluids from multiple containers in a pre-determined ratio. The apparatus has a pump, at least two fluid containers, a fluid transfer device including dip tubes to transfer fluid from the containers to the pump, a venting system that prevents the creation of pressure differentials between the containers, and a device to open and close the dip tubes so leakage from the containers can be prevented.
