a pressure tank 49 via a gas line 50 the gas of the pressure tank 49 is preferably air or nitrogen gas and pressurization of the locking and sealing strip 29 takes place preferably automatically in response to the rotation of the inner chamber 33 into the vertical closing position on the end face parts 44 of the inner chamber 33 and on the closing end faces 39 is arranged a groove for the application of a sealing strip 29 the sealing strip 29 can also be constituted by some other expandable material than a rubber hose for example an expandable metal or metal alloy which expands via electric voltage or heating in order to reduce the clearance between the closing faces 39 and the inner chamber 33 during closing and opening the end faces 44 of the inner chamber 33 are convexly shaped and the two closing end faces 39 are concavely shaped fig6 if the baggage has been deemed to be at risk of detonation the inner storage chamber 33 is closed in the horizontal position by the steel blind 46 of the inner chamber 33 being lowered over the two open end face parts 44 the storage chamber 33 is thereafter rotated into its vertical position in which the locking mechanism of the closing end faces 39 is activated the function of the steel blind 46 is to close the inner storage chamber 33 for incoming and outgoing baggage and keep the baggage in place in the storage chamber 33 during the rotation of the storage chamber 33 on the inner side of the two sides 41 of the storage chamber 33 are arranged two vertical supporting walls 51 on which are mounted the drive rollers 53 of the.
