US Patent 7237813 Box lifting device

A pair of devices for lifting boxes is disclosed. Each device comprises a handle, lifting surface, lifting plate and a plurality of lifting members in the form of angled teeth. During use, the teeth of each device are inserted into opposite sides of a corrugated box. A user is then able to lift the box using the temporary handles. The teeth are sized to avoid damage to the contents of the box. The teeth may be punched into a removable metallic lifting plate. The design of the teeth provides a sufficient amount of surface area for maintaining the box. During non-use the lifting plate may be removed and re-attached in an opposite orientation to prevent injuries which may be caused by the teeth.
