A wafer container comprising an enclosure portion with a door frame defining an opening for insertion and removal of wafers and a door for insertion into the door frame for closing the opening and sealing with the door frame has an improved elastomeric seal. In a preferred embodiment of the invention an elastomeric seal encircles the door, is partially inset in a groove in the door, and has a cantilevered portion extending laterally outwardly from the door to engage a sealing surface of the door and a laterally displaced sealing surface of the door frame when the door is seated. Thus a seal can be provided that is effected almost totally by flexure of the cantilevered portion rather than by compression of the seal.

1. A sealable container for containing wafers, the container comprising an enclosure portion with a door frame portion defining a rectangular open side and a rectangular door sized for insertion towards and seating in the door frame thereby closing said open side, the door frame comprising a rectangular outwardly facing flat and radially extending sealing surface and at least one latch receiver, the door comprising an interior facing surface, a parallel exterior facing surface, and four side surfaces intermediate the interior facing side and the exterior facing side, a groove inset in the four sides and extending around said door, an elastomeric seal inserted in the groove and extending around the door, the seal, in cross section, having a greater dimension aligned radially and a lesser dimension aligned axially, an inset portion positioned in the groove and an exposed portion extending outwardly therefrom, the exposed portion having a cross section with a distal portion, the inset portion and exposed portion in substantial alignment in a radial direction, the distal portion having a protruding sealing section with a rounded engagement surface, the protruding sealing section protruding substantially axially toward the enclosure portion, the exposed door frame as the door is inserted into and removed from the door frame by moving axially in a direction transverse to the greater dimension of the seal, the distal portion deflecting axially when the door is seated in the door frame, the side of distal portion opposite the protruding sealing section not being in contact with the door or door frame when the door is seated in the door frame.
