Abstract
A vacuum actuated mechanical latch is attachable to a hermetically sealable container. The latch is attached, formed, or otherwise integral with the door of the container. The latch is easily engaged and disengaged by processing equipment. Also, the latch is designed to minimize the amount of abraded particulate and further isolate any particulate generated. Further, when the door is latched to the container, the latch is not easily overcome by jarring or bumping. The lead-in surface of the latch is angled to minimize friction when the latch is forced into a first locking position.
