ABSTRACT:
A threaded closure and container arrangement having complementary annular surfaces on the closure and container which engage each other during threading and unthreading to guide the closure and container into axial alignment and to shape the relatively flexible neck opening of the container into an accurate circular shape so that complementary sealing surfaces are brought into accurate engagement with each other and so that the complementary surfaces maintain an axial force tending to maintain the closure and container in sealing relationship during at least initial unthreading movement of the closure from a fully closed position on the container
