CONNECTION STRUCTURE Russian patent published in 2012 - IPC B65D41/06 

FIELD: machine building.

SUBSTANCE: proposed structure is designed to interconnect first and second elements. Note here that first element includes cylinder-shaped connection vertical section. Note also that multiple locking flanges extend from its outer lateral surface and are spaced along its circle. Second element comprises section of connecting sidewall superimposed on connecting vertical section. Note here that multiple locking ledges extend inward from inner lateral surface of said sidewall. Note also that multiple locking flanges have no grooves while their lower edges diverge downward to produce continuous strip along circle of aforesaid vertical section. Note that with second element superimposed on first element, top edges of locking ledges slide on locking flange curvilinear edges, on said strip, to get locked at bottom position of said convex curvilinear bottom edges.

EFFECT: ease of connection in whatever direction.
