Abstract:
1. A front opening wafer container for holding a plurality of wafers in a horizontal vertically stacked and spaced arrangement, the container comprising an enclosure portion with an open front and a door to close the open front, the door comprising a wafer cushion extending vertically on an inside surface of the door for engaging the wafers when the door is in place on the enclosure portion, the wafer cushion comprising a rigid rectilinear framework with a pair of horizontal endwall rails, a left vertical sidewall rail, and a right vertical sidewall rail, a first vertical row of wafer engaging members extending inwardly from the left sidewall rail and a second vertical row of wafer engaging members extending inwardly from the right sidewall rail, each wafer engaging member having an arm portion and a wafer engagement head, the arm portion presenting a longitudinal axis and extending substantially linearly from the respective rail when not deflected, wherein the wafer engagement heads of the row of wafer engagement members extending from the left vertical sidewall rail are positioned in close proximity to the wafer engagement heads of the row of wafer engagement members extending from the right vertical sidewall rail and the longitudinal axis of each arm portion of the row of wafer engagement members extending from the left vertical sidewall rail is substantially coaxial with the longitudinal axis of the arm portion of a separate one of the wafer engagement members in the row of wafer engagement members extending from the right vertical sidewall rail when the wafer engagement members are not deflected.
