ABSTRACT:
The invention provides a closable container having an access opening closable by closure doors comprising preferably two hinged doors hingedly mounted on the container on opposed sides of the access opening, and a releasable locking mechanism for the doors. The locking mechanism includes a pair of T-shaped pressure plates hingedly mounted by means of hinge pins on opposed sides of the access opening, to be pivotally displaceable around axes disposed at right angles to the pivotal axes of the hinged doors, to a closed position in which they are positioned over the doors to overlap at least partially with the edges of each door. An engagement block with a handle is provided to hold the pressure plates and the doors in the closed position, the engagement block being rotatably displaceable from a disengaged position to an engaged position in which it engages the pressure plates to exert force on the plates so as to press the edge regions of the doors uniformly against the sides of the access opening.
