A packing container assembly having an inner and an outer elongated hollow member each having a closed end and an open end, with the open end of the inner hollow member insertable into the open end of the outer hollow member to place the hollow members in longitudinal sliding engagement. A pair of interlocking devices are formed, one on an inner surface of the outer hollow member which comprises an inwardly extending protuberance, and the other on an outer surface of the inner hollow member, which comprises a plurality of spaced depressions extending inwardly from an inner wall surface thereof. The plurality of depressions are each adapted to receive the protuberance when the two members are joined together. A pair of elongated slots extending through the wall portion of the outer hollow member are provided on each side of the protuberance to enhance the flexibility of the wall portion at the protuberance and minimize any resistance to slidability at the interface. In a different embodiment, an outwardly extending thumb-tab is provided between the elongated slots to permit manual withdrawal of the protuberance from the depressions.
