Abstract:
A method of forming a candle can including the steps of:deep drawing a cylindrical blank to produce a can having an upstanding cylindrical wall having a height which is at least 50% of the diameter of the cylinder; near the end of the deep drawing operation stamping a complex shape in the center of the blank to form a can bottom, the complex shape including; a peripheral annular ring forming the base of the bottom and occupying no more than about 30% of the cylinder diameter, and a central dome having a bottom wall surface and a mounting surface, the mounting surface raised from the bottom by at least {fraction (3/16)} inches to form a seat for locating and supporting a wick sustainer, the bottom wall surface joining the mounting surface to the peripheral annular ring; and forming the angle of the dome bottom wall surface with respect to a plane through the annular ring sufficiently shallow to allow formation of the peripheral annular ring and the central dome without puncture of the bottom during the metal stretching occasioned during stamping of the bottom configuration.
