ABSTRACT:
A portable liquid dispenser for dispensing one of two liquids from a single vessel has a base with first and second separate horizontally disposed compartments separated by a liquid-impermeable barrier, a neck secured to the base and mounting handle, a valve assembly including first and second valve elements rotatably mounted in the neck for swinging between open and blocking relationship with the compartments and a valve seat in snap-fit relationship with the valve assembly. The valve elements swing downwardly for alternate abutment with the impermeable barrier and into sealing engagement with the valve seat. An actuator is coupled to the valve elements through a shaft and is positioned for actuation by the thumb of a user which grips the handle. The base can be formed in separate injection-molded sections which are secured together and which have a stainless steel bottom integrally molded into the bottom of the section.
