Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
273 words
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.
Claim 2
Dependent Claim
273 words
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.
Claim 3
Dependent Claim
30 words
Elongated packing container, as set forth in claim 1, wherein said teeth on said first hollow body have a rectangular cross-section in the axial direction of said first hollow body.
Claim 4
Dependent Claim
94 words
Elongated packing container, as set forth in claim 1, wherein said threads are shaped as buttress threads each having a first flank facing toward the open end of said second hollow body and a second flank facing toward the closed end of said second hollow body, said first flank extending from the root thereof is inclined toward the closed end and at an oblique angle to the longitudinal axis of said second hollow body and said second flank extends from the root thereof substantially perpendicularly to the longitudinal axis of said second hollow body.
Claim 5
Dependent Claim
42 words
Elongated packing container, as set forth in claim 3, wherein each of said threads has a crest portion extending between the ends of said first and second flanks remote from the roots thereof and said crest portions have a convex rounded shape.
Claim 6
Dependent Claim
44 words
Elongated packing container, as set in claim 4, wherein the center of each of said rounded crest portions is located on the root circle of said threads which are in juxtaposition to the outer crest surfaces of said teeth of said first hollow body.
Claim 7
Dependent Claim
58 words
Elongated packing container, as set forth in claim 1, wherein the closed end of at least one of said first and second hollow bodies has oppositely disposed surfaces located outwardly from and extending chordally of the longitudinal axis thereof for engagement with a tool for effecting rotation of the one of said hollow bodies relative to the other.
Claim 8
Dependent Claim
30 words
Elongated packing container, as set forth in claim 1, wherein two said rows of teeth are formed on said first hollow body with said rows located diametrically opposite one another.
Claim 9
Dependent Claim
34 words
Elongated packing container, as set forth in claim 1, wherein said teeth extend in the circumferential direction for an angle relative to the longitudinal axis of said inner body in the range of 15°-30°.
Claim 10
Dependent Claim
24 words
Elongated packing container, as set forth in claim 1, wherein said first and second hollow bodies are formed of a deformable elastic plastics material.
Claim 11
Dependent Claim
35 words
Elongated packing container, as set forth in claim 1, wherein said closed end faces of said first and second hollow bodies are formed of a resilient material and have a slightly outwardly directed curved configuration.
