Abstract: A shipping container having an internal plastic bag is described, as is the method of forming the container. A flat container blank if first formed. This differs from a conventional blank only in that it has blind score lines centered vertically on each of the end panels. Adhesive strips are placed on or adjacent the major score lines separating the face and end panels of the container. Either a flat or gusseted bag is then laid on the blank with a sealed bottom edge adjacent the outside edges of the bottom flaps of the container. An open end of the bag extends beyond the upper edge of the container. The blank is then folded along the blind score lines to form a partially assembled container that can be shipped flat. Final assembly can be readily done in the field. The container eliminates the need for field insertion of the bag where one is required.

Abstract: A carton blank is etched with a laser to remove at least a portion of a coating material on a glue panel area of the carton blank. The laser-etching process allows the use of cold-resin or other standard glue in manufacturing a carton from the carton blank, instead of a more expensive specialized glue which would be otherwise required to provide an adequate bond for the carton. The laser-etching process is controlled as a function of the coating material required to be removed from the glue panel of the carton blank, the speed of the carton blank as it is processed through the system, and the dispersion characteristics of the laser beam.

After a blank has been cut out, a flexible material strip is connected with the side wall panels and a number of end wall panels through adhesion. The material strip is attached to each of a number of other end wall panels while leaving clear two triangular portions not provided with adhesive which are located adjacent the free edges of the corresponding end panel. The blank is then erected to form a box through folding and adhesion with the adhesive being applied to the blank by at least one stamp. The stamp is of such design that the adhesive layer on the relevant end wall panel terminates at some distance from the edge of the adjacent end wall panel.
