Patent

CA 2145940

A substantially transparent carrier for carrying a group of items, such as bottles which hold beverages, is made of a plastic material which includes a chemical blocking agent. The carrier includes a machine readable bar code thereon. Each item includes an individual machine readable bar code thereon which is at least partially covered by the carrier. The chemical blocking agent is capable of blocking, by reflection or absorption, light having a narrow wavelength "tuned" or selected to prevent the individual bar codes on the items from being read by a typical bar code reader beam while allowing the bar code on the carrier to be read.
