Title: Wall construction for containers

Abstract: A drawn and ironed container with a profiled bottom wall is disclosed herein. The profiled bottom wall includes an ellipsoidal dome surrounded by a substantially vertical wall portion which merges with the side wall of the container along an outwardly directed bead. The configuration of the bottom wall substantially increases the resistance to buckling when the container is filled with pressurized product.
