Abstract: A pressure container made of aluminum, for example, is disclosed and includes a generally cylindrical body and a self-standing integral bottom which has a downwardly extending peripheral skirt portion. The bottom of the container has an inside radius of about R1 and an exterior configuration which, in vertical crosssection along a diameter line includes: I. A DISC-LIKE, CIRCULAR CENTRAL PORTION; II. A CONCENTRIC UPWARDLY CURVED PORTION WHICH IS CONTIGUOUS WITH THE CENTRAL PORTION AND HAS A RADIUS OF ABOUT 0.22 R1; iii. a concentric downwardly curved portion contiguous with the skirt portion and having a radius of about 0.19 R1; and IV. A GENERALLY FLAT CONCENTRIC PORTION CONTIGUOUS WITH AND BETWEEN THE CURVED PORTIONS. The thinnest portion of the bottom is in the upwardly curved portion and is not less than about 1.5, preferably 2 times the wall thickness of the cylindrical body.
