Abstract
A seamless candle can is formed in a blank and draw operation, and includes a complex bottom structure formed at the end of the drawing process. The bottom structure includes an annular base which occupies less than 30% of the area of the bottom surface, and a raised central platform for supporting a wick structure. The platform is raised at least 0.25 inch above the container bottom. A gently sloping surface joins the annular support ring to the central platform. The distance by which the platform is raised and the angle of the connecting surface are adapted to prevent overstretching of the material during the formation of the bottom, so as to prevent the formation of holes in the seamless can which would cause leaks. The central platform serves to support a wick sustainer at a location above the bottom of the can in order to reduce the possibility of flash-over.
