Abstract
A cargo container of unitary construction surrounds a cargo hold and has an opening into the cargo hold defined by an edge. A flange extends along the edge of the opening and projects into the cargo hold to form a seat. A door having a panel defined by a border covers the opening. A bite extends along the border of the panel and projects away from the panel to contact the seat. When the door is covering the opening, the bite is positioned against the seat and is juxtaposed with the flange. In response to an explosive detonation in the cargo hold, the bite is forced against the seat and transfers the explosive force from the door to the container. If a seal is present on the seat, the bite is forced against the seal to form an airtight lock in the cargo container.
