METAL AEROSOL CONTAINER AND METHOD OF MANUFACTURE

摘要

Two-piece metal aerosol container (20) and method of manufacture are provided in accordance with the present invention. A rolled and longitudinally welded cylindrical tube (15) forms the container body (26), including a cylindrical sidewall and reduced diameter shoulder (109) and neck portions (110) (formed by a sequential necking process), while a separate metal base component (104) is attached via a crimped seam (106). The open-top end of the container neck portion is curled to receive a manually actuatable dispensing valve assembly. The container is resistant to internal pressures in excess of 311 psi (2150 kPa) and offers increased strength and pressure resistance (compared to a three piece rolled metal aerosol container), while being easy to manufacture and low in cost.
