Abstract: A container suitable for storing and transporting hazardous materials such as alkali wet cell batteries in an aviation environment includes a container body and a hinged lid made of cross linked polyethylene, latches, and a triple tongue-in-groove seal around the rim of the container opening. The triple tongue-in-groove seal includes two smaller tongue-in-groove seals with a larger tongue-in-groove seal disposed therebetween. The larger tongue-in-groove structure provides structural strength to help prevent the lid from skewing when the container suffers stress such as an impact at a corner, and also helps to guide the lid and base into proper alignment when the lid is being closed. The smaller tongue-in-groove seals provide double redundant sealing to help contain hazardous materials inside the container without making the rim of the container excessively wide.

Abstract: A universal airplane jet engine turbine blade packing case assembly for securely holding a matched turbine blade pair of various shapes, sizes, and profiles for safe shipping and storage includes a molded housing having a base and a hinged lid, with the housing being partitioned into two sections, one section for each turbine blade. Each section includes a dial rotatably affixed to the inside of the base, with a tapered slot in the dial for slidably receiving and engaging a turbine blade root when the slot is in a vertical loading position. When the root has been slid into the dial, rotating the turbine blade causes the dial to also rotate, which causes the slot opening to rotate behind a portion of the housing such that the turbine root is now positively held within the dial. The turbine blade and dial are rotated further until the turbine blade chord is aligned vertically in a stow position.
