aerosolbehallare of metal and with a vesentligen cylindrical behallarmantel and by crimping on the cape party bottom and seen to framstella such containment bottle

摘要

A metal aerosol dispensing can has a cylindrical side wall and a separate bottom fitted to the side wall by a rolled joint including overlapping edges of the bottom and of the side wall. After forming the joint, the bottom and joint are pushed wholly within the cylindrical side wall, the lower part of the side wall thus being folded inwardly. The folded parts of the side wall can then be inwardly deformed to form a rim supporting the joint.
