Claim:
A container for holding a single wafer comprising: an enclosure portion having a top, a bottom, a pair of opposing sides, a back and an open front defined by a door frame, the door frame having a pair of latch recesses defined therein; a wafer support in the enclosure; and a door engagable in the door frame for sealingly closing the open front, the door comprising: a chassis defining a door enclosure; and at least one operable latching mechanism in the door enclosure, the latching mechanism including a selectively rotatable cam having a pair of laterally projecting opposing wings, the wings being fixedly coupled to the cam so as to rotate with the cam, the cam rotatably shiftable between a first favored position wherein the wings are completely within the door enclosure to enable the door to be engaged and disengaged from the door frame, and a second favored position wherein the wings extend laterally outward from the door enclosure so as to engage in the latch recesses in the door frame when the door is engaged in the door frame, the latching mechanism further including a spring disposed to provide a biasing force for urging the latching mechanism toward each of the first and second favored positions.
