ABSTRACT:
A packing container is formed of a pair of cylindrically shaped axially elongated hollow bodies disposed in coaxial alignment with one fitting telescopically into the other. A row of teeth is formed on and projects outwardly from the inner hollow body and the row extends in parallel with and for the full axial extent of the inner hollow body. The teeth extend in the circumferential direction of the inner hollow body. However, the teeth extend for only a fractional angular portion of the circumferential dimension of the inner hollow body. Threads are formed on the inner surface of the outer hollow body adjacent its open end and the teeth interengage with the threads. Both the teeth and threads extend at the same oblique angle to the longitudinal axis of the hollow bodies. The teeth have a rectangular cross-sectional shape while the threads are formed as buttress threads.
