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.

Elongated packing container comprising a first and second cylindrically shaped axially elongated hollow body each having a closed end and an open end with the open end of said first hollow body telescopically insertable into the open end of and being coaxial with said second hollow body, said second hollow body being capable of telescopically receiving at least a part of the axial length of said first hollow body, said first hollow body has a row of teeth with the row extending for substantially the full axial length of said first hollow body and being parallel with the longitudinal axis thereof, said teeth extending outwardly from the outer surface of said first hollow body, each of said teeth extending substantially transversely of the axial direction of said first hollow body and in the circumferential direction of said first hollow body for a small angular extent thereof, and means on said second hollow body adjacent the open end thereof for engagement with said teeth on said second hollow body, wherein the improvement comprises that said teeth are disposed at an oblique angle to the longitudinal axis of said first hollow body, said means on said second hollow body comprises an annular portion of individual threads having a short axial length relative to the length of said row of teeth and to the axial length of said second hollow body, said threads being inclined to the longitudinal axis of said second hollow body at substantially the same angle as said teeth form with the longitudinal axis of said first hollow body, and said threads extending inwardly from the inner surface of said second hollow body.
