ABSTRACT:
The present invention is directed to a lid unit having a latching mechanism for firmly fixing the lid unit to a container body for containing semiconductor wafers and the like, which latching mechanism can be easily disassembled for cleaning and drying of its components, and to a wafer presser for retaining the semiconductor wafers in position when the container is shaken. The latching mechanism includes a locking member which, when projected, secures the lid unit to the container body; an actuator for moving the locking member between projected and retracted positions; a tip-side cam for pressing a tip portion of the locking member in one direction relative to the lid unit when the locking member is projected by the actuator; a base-end lower cam for pressing a base-end of the locking member in a second direction, opposite the one direction; and a base-end upper cam and a cam projection follower for pressing the base-end in the second direction. The wafer presser is supported by a supporting projection bar formed with its ends thinner than its center portion.
