Patent number: 4399915Abstract: A corner post made of folded corrugated paperboard is inserted into the corner areas of cartons containing, for example, large appliances, such as stoves, refrigerators, washing machines, or the like. The corner post is a multi ply device which ensures that there will be adequate space between the appliance and the carton wall, and which provides strength for the carton so that multiple filled cartons can be stacked on top of each other. The post is provided with fold lines which are made up of alternating cuts and scores to provide for easy folding of the post. The post is machine folded and glued to a flattened form which is suitable for bulk shipment. The post is easily transformed from the flattened to the erected form and inserted into the corner areas of the cartons.Type: GrantFiled: October 15, 1981Date of Patent: August 23, 1983Assignee: Champion International CorporationInventor: John F.

Patent number: 4239148Abstract: A box for storing files is formed from a single blank of paperboard. The blank consists of a centrally located bottom wall panel having side wall panels foldably connected thereto. Each of the centrally located bottom walls panels and side wall panels have an end wall panel extending from a transverse edge thereof so that when the side wall panels are folded 90.degree. relative to the bottom wall panel, the end wall panels on the transverse edges of the side walls and bottom walls can be overlapped and locked together. Connected to the outer longitudinal edges of each of the side wall panels is a top wall panel substantially half the width of the centrally located bottom panel. The top wall panels are adapted to be folded 90.degree. relative to the side walls to form a cover for the box. Longitudinally extending tabs extend from the transverse edges of each of the top wall panels and can be inserted within an opening in the end walls to lock the top wall panels in place on the box.Type: GrantFiled: July 9, 1979Date of Patent: December 16, 1980Assignee: Champion International CorporationInventors: John F.
