ABSTRACT:
A metallic pressure vessel or container, made of a thin aluminum or aluminum alloy sheet coated with a resin suitably, used for a small size beer container. The vessel is composed of (a) a main body member of bottomed cylindrical form, with a bulge in the central part thereof precessed by a novel method, provided with at least three protrusions and recessed beads disposed therebetween alternately, for stable setting and reinforcing, and (b) a lid member, for covering the former body, which is made into an inverted bowl shape, with a mouth portion integrally formed for being crowned thereon, and provided with a plurality of small wave like patterns consisting of continuous and smooth hills and valleys. Those two parts are generally made by multiple deep-drawing processes and joined together by the double seaming method. The process of the mouth portion making is characteristic in its burling and curling processes.
