A reusable container system comprising a container for holding a bulk quantity of liquid or other fluent material. The container has top, bottom and side walls, a port in the top wall of the container, a closure for the port having a tamper-evident connection with the container for indicating removal of the closure from the container, and a suction tube assembly attached to the closure and extending down into the container. A one-way check valve in the suction tube assembly permits flow of liquid out of the container but prevents flow into the container through the suction tube. The closure on the port is formed for releasable connection of a pump thereto whereby, after arrival of the container at a location where the contents of the container are to be dispensed, a pump may be releasably connected to the closure and then actuated to pump liquid from the container via the suction tube assembly. When the container is emptied the pump may be disconnected from the closure for transport of the container to another location for refilling. A method of using the system is also disclosed.

A reusable container system comprising a container for holding a bulk quantity of liquid or other fluent material, said container being adapted to be filled with said material at a first location and transported to a second location for unloading off material from the container, pump means for pumping said material out of the container at said second location, said container having top, bottom and side walls, a port in the top wall of the container through which material in the container may be unloaded by said pump means, a closure for closing said port, said closure having a tamper-evident connection with said container for indicating removal of the closure from the container, and a passage through the closure, suction tube means attached to said closure and extending down into the container, said suction tube means having an upper end communicating with said passage through the closure and a lower end adjacent the bottom wall of the container communicating with the interior of the container for suction of liquid from the container up through said suction tube means and then out of the container via said passage, a one-way check valve in said suction tube means permitting flow of liquid out of the container through said suction tube means but preventing flow of liquid into the container through said suction tube means, and connector means for releasably connecting said pump means and said container with said pump means in fluid-flow communication with said passage through the closure whereby, after arrival of said container at said second location, said pump means is adapted to be releasably connected to the container for removal of liquid from the container and disconnected from the container after the container is emptied for transport of the container to another location for refilling, said suction tube means comprising a tubular fitting attached to said closure, and a suction tube connected to said tubular fitting and extending downwardly to a point adjacent the bottom of the container, said suction tube and fitting being movable relative to one another to accommodate, for example, deformation of the top and bottom walls of the container, and spring means urging said suction tube downwardly relative to said fitting toward the bottom wall of the container.
