Abstract
Enclosure for storing sensitive materials are disclosed. They may be in a special container (1), sealed and purged, replacing the internal atmosphere with an inert purge gas, and leaving the sealed container slightly pressurized. By hinging a lid or door (5) to the container via hinges (12, 13), the respective parts of which can move relative to one another translationally, at least when the door or lid (1) is in the closed position, and in a direction perpendicular to the plane of the door or lid, much improved sealing may be achieved. The invention also relates to methods used to deliver and duct the purge gas within the container to ensure good purge gas delivery and mixing.
Claims5
A storage enclosure comprising a sealable box having an open face fitted with at least one door or lid, said at least one door or lid being mounted via at least one hinge, wherein component parts of a hinge of said at least one hinge are attached respectively to said box and said at least one door or lid and are configured to provide a first degree of freedom of movement which is rotational and a second degree of freedom of movement which is translational, allowing the component parts of the hinge to be moved translationally relative to each other, and the box including a plurality of latches mounted around a perimeter of the open face of the box which, when actuated, effect translational movement of the component parts of the hinge one relative to another to seal the at least one door or lid closed against the box, and said box including inlet and outlet ports located on the box to enable purge gas to be passed through the storage enclosure, and further including a plurality of supporting compartments within the box.
