ABSTRACT:
A cardboard carton lid is constructed so that the carton may be securely packed and shipped without the necessity for plastic strapping, and using lower strength paperboard than is conventionally provided, yet allow the carton lid to be reused. The lid has elongated side panels with first and second parallel lines of weakness (e.g. perforations) formed in them. The bottom, fastening portion of the side panels is secured--as by adhesive--to the carton body side walls. A blank, and enlarged grasping portion in the carton lid side panels at the lines of weakness allow a user to grasp the strip between the lines of weakness and detach the lid from the securing portions of the side panels. The lid can be reused after detachment. The carton is packed with nondeformable material such as business forms which extend above the top edge of the carton. After the lid is compressed, to reduce voids in the material, the components are maintained in the compressed condition, and the side panels are glued to the carton body side walls, without interfering with the ability of the lid to flex at the lines of weakness. The lid will flex at the lines of weakness during use.
