The invention concerns a coding process and coding device for applying an optically readable code mark on a container (2), in particular a plastic bottle. The container (2) on which the code marking is to be applied travels, by means of a conveying apparatus, past a coding station (3) where the code mark in the form of depressions is made by a laser beam. A coding process and coding device of this type are considerably simplified if the bottle (2) is fixed in relation to the conveying apparatus and the laser beam is directed onto a surface of the bottle from above or below, essentially along the axis of the bottle or at an angle of 7 to 15 DEG to the axis of the bottle, and moved over the surface, which has a horizontal component. |
