Abstract: Two-piece metal aerosol container and method of manufacture are provided in accordance with the present invention. A rolled and longitudinally welded cylindrical tube forms the container body, including a cylindrical sidewall and reduced diameter shoulder and neck portions (formed by a sequential necking process), while a separate metal base component is attached via a crimped seam. 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.

Abstract: The present invention relates to a metal container for microwave oven of the present invention which comprises an integrally molded body which in turn comprises: a base enabling the container to rest on a surface; and a wall divided into at least one wall section extending from the perimeter of the base in order to hold products, with a maximum height of 40 percent of the wavelength of the radiation emitted by the microwave oven; wherein all the angles formed by the inner part of the container at the intersection of planes between the sections are greater than 90° (?/2 radians) and said intersections have a chamfer shape with an arcuate section having a radius of at least 0.5 mm, the ends of the arc being at the points at which the planes which intersect in order to form the angles are tangential to the arc.
