ABSTRACT:
A plastic container for storing and shipping semiconductor wafers comprising a wafer carrier of substantially rigid and transparent material supporting the wafers and maintaining the wafers in spaced relation to each other, top and bottom covers for the wafer carrier formed of stiff but resiliently flexibly yieldable material, the wafer carrier having upper and lower enlarged rim portions extending around the peripheries of the top and bottom of the wafer carrier and being embraced by enlarged peripherally extending rim portions of the top and bottom covers, the top and bottom covers having partially cylindrical panels with elongate beads or ridges formed thereon to engage and maintain the edges of the wafers spaced from the partially cylindrical surfaces, offset tabs on the wafer carrier and top and bottom covers facilitating of flexibly lifting small portions of the covers off the wafer carriers and then progressively disengaging the covers from the wafer carriers; a package comprising a multiplicity of cover trays with compartments receiving the shipping containers therein, the cover trays supporting the containers at the tab portions on the wafer carriers and the cover trays also bearing downwardly on the side edge portions of the cover to maintain the covers in closed condition on the wafer carrier.
