Abstract
Inadvertent rupture of frangible tamper evidencing means during application of threaded closures is reduced by axially pressing the closure partially onto the container, without rotating the closure, until a downwardly tapered retaining means on the closure is engaged by an upwardly tapered locking rib around the container finish. This engagement centers and positions the closure so that the axis of the closure is aligned with the container axis. The closure is held in alignment to prevent cocking or misengagement of the threads until the closure is thereafter turned to tighten it on the container.
