Abstract

A packaging system having a bar code reader integrated therein for conveying information concerning the size and filling requirements of a product to a packaging machine which will produce the product. The packaging machine is capable of consecutively filling cartons with different products in a single production cycle. The bar code reader provides this information from the bar code placed on every blank that is to be produced into a formed, filled and sealed carton. The filling system of the packaging machine may have a primary and secondary product for mixing in a package to produce a final product. Alternatively, the filling system may have several filling pipes, each filling pipe dispensing a different product. The bar code reader instructs the conveyor under which fill pipe a particular carton should be filled to match the product with the carton.
