UV-C light has been used for sterilisation generally, including irradiating the external surface of bottles. UV-C lamps used in previous applications had certain blind spots, such as the ends (electrodes). Provided is a continuous packaging process, in aseptic conditions, which uses UV-C light to sterilise bottles and closure caps which are intended to contain alimentary, cosmetic and pharmaceutical products, wherein the entire internal surface of the bottles is innovatively sterilised by means of U-shaped lamps specially formed to be introduced through the mouth of the bottles, thus preventing irradiation blind spots, along with preliminary bottle preparation and formation, cap removal, filling and closing stages.
