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.

Deep drawn candle can with formed safety bottom

This invention is directed to a candle can of the type normally filled with an ignitable fuel. The candle can includes an upstanding continuous sidewall that is integrally coupled to a stamp formed candle can bottom structure at an outer periphery of the candle can bottom structure. The integral coupling of the sidewall to the bottom structure establishes a can support ring to engage a support surface. The stamp formed can bottom structure is so formed as to provide within the can an internally upwardly directed dome upon which a candlewick carrying element may be securely located within a dish shaped indentation in an apex region of the dome. In a preferred embodiment of the invention the intersection of the sidewall and the upwardly directed dome of the can bottom structure establishes an annular internal volume of fuel separated by the dome from a candlewick flame near the end of both the candlewick life and the supply of fuel. This just described arrangement of an annular internal volume of fuel which surrounds the dome minimizes flash-over while also creating the annular ring supporting surface for the candle can base which reduces heat transfer from the candle fuel and flame to the support surface.
