Abstract
A corrugated paperboard corner post as utilized for packaging in a shipping container is formed by folding over a portion of corrugated, the upper and lower portions of the corrugated being divided into three panels each by slit score lines extending the length of the corner post, and gluing the outer panels of the upper and lower portions together. The corner post is initially formed in a flattened configuration to facilitate its shipment and handling in bulk and may be quickly and easily re-configured into its operable orientation by pushing both edges together and causing the panels to fold about their score lines.
Claims15
A corner post for insertion into each of the corners of a shipping container to hold an item contained therein in a spaced apart relationship from both adjacent sidewalls of said container as said container is shipped, said corner post being comprised of a single, continuous piece of substantially rectangular corrugated paperboard, said corner post having means defining a plurality of panels therein, at least two of said panels being joined over a substantial portion of their faces, said corner post having a first portion folded over a second portion in a first configuration so that said corner post is substantially flat in the first configuration, and wherein said corner post may be quickly and easily realigned by folding into a second, operable, configuration, said second configuration being characterized by space between said first and second portions wherein the first portion forms a substantially perpendicular angle and the second portion forms a substantially obtuse angle, said space being oriented to provide a cushioning effect between the item and both adjacent sidewalls.
A convertible corrugated, one piece, corner post for insertion into a shipping container, said corner post being adapted to contact an item to be boxed into said container and retain it in a spaced relationship from both adjacent sidewalls of said container as said container is shipped, said corner post having a first configuration characterized as being substantially flat to facilitate its bulk handling and shipping, and a second configuration characterized as having first and second members substantially perpendicular to each other for close fitting into the corners of the container and joining members which extend between said first and second members such that a joining member foldably extends from each of said first and second members at an acute angle and such that said joining members are foldably connected to each other to substantially form an obtuse angle, said joining members being spaced apart from the first and second members at the foldable connection for contacting the item to be boxed into said container and provide cushioned support therefor from both adjacent sidewalls, wherein said corner post has means to quickly and easily be re-configured from said first configuration to said second configuration, all of said first, second, and joining members being joined together.
