Abstract

A work surface is subjected to a corona discharge treatment and then to printing or coating. A container surface is subjected to a corona discharge treatment and preheating and then to printing or coating. The printed or coated container is heated to dry the ink or coating material and the filled materials in the container are also heat-treated. The printing or coating used is of the non-spray type. The preheating device and heating device used are of the high frequency heating type. A direction change mechanism is provided to make it possible to apply printing or coating to one container at two or more places therein and to subject containers in general to preheating and a corona discharge treatment.
