The end wall of a Bliss-type container is secured to the flanges extending from the side walls and the bottom of the container, the securing being accomplished by a single stitching device. The container body is caused to move in a closed path on a carriage or platen for the stitching operation. The term 'stitching' herein is not intended to merely mean the use of staples, but is intended to mean, for example, the use of an eyelet machine, a riveting machine, or a commercial sewing machine.
