Abstract: A wafer container includes a container body and a door. The container body has a pair of upright side walls, a top wall, a bottom wall and a rear wall cooperatively defining a container space with a front access opening. The door is removably engaged with the container body to close and seal the front access opening, and includes a front door panel, a rear door panel, and sealing means which is disposed at a periphery of the front door panel and configured to seal the gap between the door and the container body when the door is engaged with the container body to close the front access opening.

Abstract: A wafer shipping box includes a case and a positioning unit. The case includes a base, a cover, and a receiving space defined by the base and the cover. The positioning unit is disposed in the receiving space and includes a lower retaining member connected to the base, an upper retaining member connected to the cover, and a cassette disposed therebetween. The cassette includes two upright holding walls spaced apart from each other, each of which has a plurality of lateral confining slots aligned in a front-rear direction. The lower retaining member is formed with a plurality of lower confining slots, each of which is defined by two slot walls interconnected at bottom ends thereof to form a slot bottom. The slot bottoms are respectively misaligned from central positions of the lateral confining slots along the front-rear direction.
