A container assembly is provided having a first container having an interior volume defined by a confining end wall and circumferential side wall terminating at a male member containing an opening into said first container. A container segment is provided configured to be detachably coupled to the male member of the first container to extend the volume of the container assembly. The segment includes a substantially tubular side wall, one end of which terminates in a male member surrounding an opening, and terminating at a second and opposite end in a concentric recess surrounding an opening. The concentric recess in the one end of the container segment is configured to receive and form a fluid-tight seal with the male member extending from said first container when in the closed position. A cap or top member having a circumferential sidewall closed at one end and open at an opposite end is also provided. The cap is designed in a manner similar to that of the recess so that it can be readily adapted to close any male member extending from the first container or any container segment.
