A container is formed of a pair of paperboard tubular walls open at both ends and one telescoped within the other. A liquid impervious transparent liner is confined within the inner wall and the ends of the walls are closed by top and bottom closures. A fitment is attached to the liner and extends outward through the tubular walls for connection of a dispensing control valve. One or more liquid level indicating windows is provided by forming registering openings in the inner and outer tubular walls and pressing a transparent cup into each opening in the inner tubular wall before telescoping the inner and outer tubular walls together. A peripheral flange on the cup abuts the outer surface of the inner tubular wall and is secured in place by being sandwiched between the inner and outer tubular walls. In an alternative container construction, a single container wall is used, and the cup flange is abutted against and, if desired, secured to the confronting inner or outer surface of the container wall.
