Abstract:
1. A wafer container comprising: a top housing and a bottom housing, the bottom housing having an inner cavity for storage for at least one semiconductor wafer; the top housing having a base with at least one rib that extends perpendicular from the base of the top housing in an essentially circular orientation; the bottom housing having a base with at least one rib that extends perpendicular from the base of the bottom housing, wherein the at least one rib on the bottom housing is arranged concentric and at a different radius from the at least one rib that extends perpendicular from the base of the top housing, the at least one rib on the bottom housing having an arc angle of <360°; wherein the at least one rib on the bottom housing further includes at least one living hinge arranged normal to the base of the bottom housing wherein the living hinge is formed from at least one movable wall segment, wherein the at least one movable wall segment is a flexible panel within the at least one rib on the bottom housing, and wherein the at least one movable wall segment is unsupported on three sides; wherein the at least one movable wall has a first panel closing ramp, and the top housing has a second closing ramp configured to engage with the first panel closing ramp such that when the top housing is seated on the bottom housing the first closing ramp engages the second closing ramp to push the movable wall towards the inner cavity.
