Disclosed is an unique reclosable metal bottle in which a trim portion of the neck can be reused and mounted on the neck as a collar, or a separate collar provided, that has the structural rigidity necessary to form threads or lugs for recloseability. Thin wall metal bottles, having thicknesses on the order of thin wall metal cans currently in use, can be made using this process with minimal material waste since the trim neck portion is reused as a threaded collar. Structural rigidity and strength can be added by using fillers to backfill the indentations of the threads in the collar. Threads or lugs can be used, including pressure release lugs, that add both safety and convenience. Since the reclosable metal bottle is an all-metal container, the bottle can be recycled without introducing contaminants.
