Abstract: A container assembly may include a regulated tank to contain a fluid, a free tank to replenish the fluid in the regulated tank, a first expandable member between an interior of the regulated tank and ambient atmospheric pressure, a second expandable member between the interior of the regulated tank and an inflation port, a first valve to selectively connect the free tank to the regulated tank based upon a pressure differential between the interior of the regulated tank and an interior of the free tank and a second valve actuatable between an open state permitting an interior of the free tank to be pressurized and a closed state. The second valve is actuatable between the open state and the closed state based upon a position of the first expandable member.

Abstract: Examples of a container assembly are disclosed herein. An example of the container assembly includes a regulated tank to supply printing composition and a free tank to supply reserve printing composition to the regulated tank. The container assembly also includes a regulator assembly to control flow of the reserve printing composition from the free tank to the regulated tank and an inflation assembly to prime the regulated tank to supply the printing composition. The container assembly additionally includes a labyrinth to fluidically isolate the flow of ambient air into and out of the regulator assembly from the flow of a supply of air into the inflation assembly.
