Abstract

Apparatus for sealing the colorant-dispensing nozzles of machines adapted for coloring paint base material. Container assemblies of the machine provide storage of the colorants and may include metering apparatus to discharge preselected amounts of colorant through the nozzle into a quantity of paint base material. Flow control valves on the container assemblies block the discharge of colorant material from the metering apparatus. A sealing valve is attached to each nozzle to block the free end of the nozzle against air intrusion.
