US Patent 11427385 Returnable shipping container

Structures and a method for restraining a package within a returnable shipping container are provided to eliminate the need for buffering or filler materials (dunnage), particularly those materials that are environmentally unfriendly and otherwise likely to be discarded. Desirable shipping containers intended for reuse are provided with various features which enhance their utilization in a cycle of transportation out from and back to a source. These features include those associated with security, integrity, protection from the environment, addressing, automation, payment, inspection, education in volume for return, facilitation for tracking the container throughout the transport route and assurance of its eventual return.
