Abstract
A wafer container and improved door. The wafer container door has a latch mechanism cover adapted to retain and guide the latch mechanism components. The latch mechanism cover is form fitted to the latch mechanism components and may have apertures, creating a cover with an open architecture. The open architecture is of benefit for making the area under the mechanism cover more easily cleanable.
Claims21
A wafer container comprising:
- an enclosure portion having at least a top, a bottom, a pair of opposing sides, a back, an open front, and a door to close the open front, said door comprising:
- a door chassis;
- at least one latch mechanism disposed on said door chassis, said latch mechanism including an actuating portion and at least one longitudinally slidable elongate latch arm portion operably coupled therewith;
- and
- a latch mechanism cover disposed over said at least one latch mechanism, said latch mechanism cover including a panel portion substantially covering said latch mechanism and having an inner surface confronting said latch mechanism, said latch mechanism cover further including a pair of spaced-apart guide portions projecting from said inner surface adjacent said at least one latch arm portion, said at least one elongate latch arm portion being longitudinally slidably disposed between said guide portions, wherein said guide portions are adapted to slidably guide and locate said latch arm portion.

A wafer container comprising:
- an enclosure portion having at least a top, a bottom, a pair of opposing sides, a back, an open front, and a door to close the open front, said door comprising:
- a door chassis;
- at least a first latch mechanism on said door chassis, said latch mechanism including a rotatable cam and a pair of longitudinally slidable latch arms operably coupled to said rotatable cam;
- and
- a latch mechanism cover covering said first latch mechanism, said latch mechanism cover including a panel portion and a plurality of projecting guide ribs, said guide ribs being arranged so as to define a pair of channels for receiving said latch arms, each of said pair of latch arms being slidably disposed in a separate one of said channels.

A wafer container comprising:
- an enclosure portion having at least a top, a bottom, a pair of opposing sides, a back, an open front, and a door to close the open front, said door comprising:
- a door chassis;
- at least one latch mechanism disposed on the door chassis, said at least one latch mechanism including an elongate, longitudinally slidable latch arm;
- and
- a latch mechanism cover covering said at least one latch mechanism, said latch mechanism cover having means for guiding and laterally constraining said latch arm.

A wafer container comprising:
- an enclosure portion having at least a top, a bottom, a pair of opposing sides, a back, an open front, and a door to close the open front, said door comprising:
- a door chassis;
- at least one latch mechanism disposed on said door chassis;
- and
- a latch mechanism cover including an latch enclosure portion substantially coextensive with and enclosing said at least one latch mechanism, said latch mechanism cover further including a perimeter frame portion for attaching said latch mechanism cover to said door chassis, said latch enclosure portion and said perimeter frame portion defining a plurality of apertures for providing cleaning access to said door chassis and said latch mechanism.
