ABSTRACT:
A container for containing flowable material comprises a rigid tank having a top opening therein for filling the tank with flowable material. A bottom opening in the lowermost portion of the tank for evacuating the flowable material. A cap seals the top opening in the tank and a piping assembly is connected to the bottom opening. A collapsible bladder inside the tank prevents the flowable material from coming into contact with the tank. A mating top cover and bottom base assembly are shaped to receive and enclose the tank. The piping assembly includes a dispensing spout which utilizes a spout, a dry-lock or a spring valve.
