ABSTRACT:
An air cargo container includes a relatively-rigid housing defining an air-tight interior space of nominal volume within which to receive cargo. The housing substantially maintains the nominal volume of the interior space upon pressurizing or evacuating the interior space relative to ambient pressure, whereby a differential interior pressure is achieved before loading the container aboard an aircraft. Where the differential interior pressure is achieved by pressurizing the interior space, air or another suitable gas is injected under pressure into the housing. Where the differential interior pressure is obtained by evacuating the housing's interior space, or where the process of pressurizing the interior space includes a prior evacuation step, the gases drawn from within the housing are preferably analyzed to detect the presence of contraband within the received cargo. Sensors on the housing confirm that an achieved interior pressure is substantially maintained over time.
