Abstract

An arrangement for locking and unlocking a door of a container for increasing operating reliability when locking and unlocking in a simple manner and for ensuring an opening and closing of the transport container in automated operation. Particle generation is reduced at the same time. Locking elements within a door, which can move in and out, penetrate into recesses of the container to be closed when moved out along a curved path. The arrangement is particularly applicable in transport containers for wafer-shaped objects of larger diameter, in which removal and charging are effected individually in a plane parallel to the surface of the wafer-shaped object and whose container cover is removed and inserted laterally.
