Abstract: A collapsible shipping container for lightweight materials, typically edible grain particles and flakes, including a box-like sealable container and a synthetic resinous lining element, all of which are disposable after a single usage. The containers are fully preassembled in collapsed condition for storage, and require only unfolding to erected condition prior to insertion of the liner, the filling of the liner with contents, the sealing of the liner, and the closing of the container with a lid or cover.

Abstract: A fibrous collapsible shipping container for transporting small articles and particulate material and discharging the same under gravity through a bottom wall opening after the horizontal movement of a sliding door. The container may include a liner element to provide increased rigidity where the loaded contents are relatively heavy. In a second embodiment, the container includes a second medially positioned bottom wall and sliding door to provide incremental discharge of the contents, as desired.

Abstract: A corner protector is provided for insertion between a shipping container and a packaged article generally at points likely to be impacted during shipping and storage to prevent or reduce damage caused to the article. The protector includes an inexpensive and lightweight outer shell which provides adequate cushioning for the packaged article against many types of compressive loads, and an impact resistant inner plug which is more pliable and has higher structural integrity than the shell. In one form, the shell is preferably constructed of an expanded polystyrene material having an inner tapered aperture, and the plug is preferably constructed of a molded polyethylene copolymer. The plug seats within the aperture and cooperates with the shell to form a tetrahedrally shaped corner protector having the plug at the apex to absorb an impact directed toward the protected corner of the article if the container is dropped or mishandled.
