The hinged door of a cargo container is provided with a locking mechanism contained wholly or mainly within the thickness of the door to draw the door into a closed and sealed position with respect to its surronding door frame. In one arrangement the mechanism has a tapered locking bolt that can be slid into a receiving recess in the surrounding door frame such that engagement of one face of the bolt taper with the socket urges the door into its fully closed and sealed position as the bolt is extended into the recess, and when the bolt is retracted engagement of the recess with the opposite face of the bolt taper breaks the door seal. In another arrangement the mechanism has a rotary pin projecting into a cam track to effect locking engagement.

In a cargo container having at least one generally planar outer door, a locking mechanism for engagement with the surrounding door frame or the like to draw the door into a closed and sealed position therewith, the door having inner and outer faces defining its thickness and said mechanism being contained at least mainly within said thickness of the door, the locking mechanism comprising an inclined bolt having opposite faces that are inclined in the same direction away from the outer face of the door and that converge towards each other with increasing distance from said outer face in the form of an inclined wedge, guide means in the door for locating said bolt displaceably whereby the bolt is extendable from an edge of the door, a cooperating recess in the surrounding door frame receiving said extended bolt, said recess having opposite faces for engagement by said faces of the bolt, whereby one opposed pair of faces of the bolt and the recess are engaged with a wedging action as the bolt moves into the recess, thereby to urge the door into the fully closed and sealed position, and the remaining opposed pair of faces of the bolt and recess cooperate with a wedging action to break the seal between the door and its frame when the bolt is retracted from the recess.
