ABSTRACT:
A method and device for corrupting bar codes on articles and for packing the articles conveys the articles from an orienter to a packer. Each of the articles has a bar code which is positioned by the orienter to face a marking device. The orienter can be a linear device or a carousel device with a rotatable table. The marking device is either an ink jet or laser which will place a pattern through the bar code of each article. The packer will place a plurality of the articles in an open ended receptacle such as a carton. Some of the bar codes will be visible through the open end of the receptacle. Due to the mark through these bar codes, however, these exposed bar codes cannot be read by an optical scanner.
