Abstract of the Disclosure A small-mouthed container having a continuous resinous coating covering the interior of said container and end, said interior coating having a thickness less than about one mil and being free of low molecular weight organic matter, is dis- closed herein. Typical containers are food and beverage con- tainers having cylindrical metal walls and circular disc-shaped ends. The coating is typically a comestible coating having a thickness of less than one mil and having no occluded solvent therein. Thermoset resinous coating are particularly useful. A coating is applied by flowing a mixture of gas and fine resin particles through a nozzle into the vicinity of a plasma arc flame which at least partially melts the surface of said particles and propels said particles into a rapidly spinning container having one closed end. A predetermined quantity of resin is pulsed through the nozzle to deposit on the interior of the container a uniform coating of resin par- ticles. A cured coating can be obtained by introducing the particles into a plasma flame for a sufficient residence time to liquify substantially said particles and to impart sufficient energy therein that said particles cure upon said substrate without subsequent addition of energy. Alternatively, the con- tainer coated with uncured particles can be heated in a curing oven for a period and at a temperature sufficient to produce a cured resinous coating.
