AEROSOL CONTAINER

摘要

An aerosol container is produced from a feedstock comprising steel strip coated on one or each of its surfaces with a coherent laminated coating, the process including the steps of: (a) drawing the feedstock into a cup; (b) redrawing, and optionally ironing, the drawn cup to produce a cylindrical body in which the side walls are of reduced thickness; (c) shaping the open end of the cylindrical body (i) to form on its rim a flange to accommodate a separate preformed steel crown for receiving a valve cup, thereby producing a two-piece steel aerosol container; or, (ii) to form a neck for receiving a valve cup, thereby producing a one-piece aerosol container. Preferably, the feedstock comprises a low carbon steel strip, for example, steel strip with a carbon level of less than or equal to 0.04 % by weight.
