A conjugate pair of self-aligning joints are formed in the peripheral edges of a relatively thick walled hemisphere which when brought together form a hermetically sealed ball shaped container. The interlocked joint utilizes oppositely disposed, grooved, deflecting flanges which nestle and lock one within the other. The hemispheres after being forcibly pushed together have an interlocked joint therein which resists inadvertent disassembly due to vibration or shock.

An interlocked joint which comprises: a hollow male section having an annularly triangularly shaped male flange located on a peripheral edge of said hollow male section, said male flange having a convex male flank surface disposed on an exterior wall of said male section, a male shoulder section positioned adjacent to said male flank surface, an annular male flank groove located adjacent to said male shoulder section, said male flank groove having an annular gasket groove operatively disposed therein, and a first annular deflecting groove disposed in an interior wall of said male section, said male flank groove and said first annular deflecting groove being oppositely positioned on said hollow male section to provide a male necked down flange section; a hollow female section having an annularly triangularly shaped female flange located on a peripheral edge of said hollow female section, said female flange having a convex female flank surface disposed on an interior wall of said female section, a female shoulder section positioned adjacent to said female flank surface, an annular female flank groove located adjacent to said female shoulder section, a second annular deflecting groove disposed in an exterior wall of said female section, said female flank groove and said second annular deflecting groove being oppositely on said hollow female section to provide a female necked down flange section; and gasket means proximately disposed in said annular gasket groove for providing an hermetic seal between said male section and said female section when said hollow male and female sections are axially aligned with each other and forcibly pushed into interlocking engagement with each other, said male and female flanges being deflected away from each other when said male and female flank surfaces slide over each other, said male flange entering into said female flank annular groove and said female flange entering into said male flank annular groove to permit said male and female shoulder sections to make contact with each other and to resist movement of said male and female sections away from each other.
