摘要:
Improved bottom for a seamless metal container body wherein the central portion of the bottom that includes a stiffening embossment is joined to the other portions of the bottom in an improved manner by a hinge-like section that permits selected and controlled outward flexing or bulging of the bottom when the container is sealed and subjected to internal pressures developed by the contents of the container. Despite such outward flexing of the bottom, the container still is provided with a stable bottom to rest upon in its sealed and pressurized condition.
