Sealed window for dry box

A storage box comprising

• a container having a bottom surface and a plurality of side walls that extend outward from a perimeter of the bottom surface and that collectively form a perimeter edge, the container configured and arranged to receive a portable electronic device;
• a lid configured and arranged to couple with the container, the lid having an inner surface, an outer surface, and a perimeter edge configured and arranged to mate with the perimeter edge of the container along the opposing perimeter edges of the lid and the container, the lid defining a window aperture having a circumference that is smaller than the perimeter edge of the lid;
• a hinge coupling the lid to the container, the hinge extending along a portion of the perimeter edge of the container, the hinge also extending along a portion of the perimeter edge of the lid, the hinge configured and arranged to enable the storage box to transition between an open position and a closed position in which the perimeter edge of the lid aligns with the perimeter edge of the container;
• a rigid first contact surface disposed along the inner surface of the lid, the first contact surface defining a first groove forming a closed loop extending around the circumference of the window aperture;
• a rigid second contact surface disposed opposite to the first contact surface, the second contact surface defining a second groove, the second groove forming a closed loop aligned with, and directly opposite, the first groove;
• and
• a window disposed along the inner surface of the lid beneath the entire window aperture, the window having a circumference that is larger than the circumference of the window aperture and smaller than the perimeter edge of the lid, wherein the window comprises
• a flexible membrane having a planar surface and a uniform thickness,
• at least one stiffener disposed along a portion of the flexible membrane extending directly beneath, and visible through, the window aperture, the at least one stiffener formed as an elongated strip of stiff yet resiliently-flexible material forming a closed loop of material extending along the surface of the flexible membrane beneath the window aperture, and
• a peripheral sealing lip disposed along the circumference of the window, the peripheral sealing lip formed as an increased thickness of the flexible membrane extending around the entire circumference of the window;
• wherein the peripheral sealing lip is configured and arranged for being compressed between the first contact surface and the second contact surface to form a seal between the first contact surface and the second contact surface;
• wherein when compression of the peripheral sealing lip between the first contact surface and the second contact surface causes the peripheral sealing lip to fill at least one of the first groove or the second groove.
