Abstract
A packing container assembly particularly for storing elongated objects is formed with inner and outer elongated interfitting hollow members each having a polygonal cross-sectional configuration with a closed end and an open end longitudinally slidable relative to each other. Each of the hollow members is formed with interlocking members which cooperate to fix the hollow members in engagement with each other. The interlocking members on the outer hollow member are inwardly projecting webs located adjacent the open end of the outer hollow member at corners thereof and the interlocking members of the inner hollow member are outwardly projecting elevations spaced apart in the longitudinal direction thereof with elevations being provided at at least two diagonally opposite corners of the inner hollow member lying in a common plane extending perpendicularly to the longitudinal direction thereof. The hollow members are formed with rounded corners having specific radii which differ from each other.
