<p>PROBLEM TO BE SOLVED: To provide a packaging container which can be smoothly opened or closed and does not break or contaminate a semiconductor wafer which is housed therein. SOLUTION: A first divided container 11 has a flat portion perpendicular to the right-left direction that opens and closes the container 11 at the end of the peripheral wall 11a, and the flat portion has a hole 11f elongated in the up-down direction. A rectangular projection 11g extends in the right-left opening direction from the center of the flat portion, and a plurality of retaining holes 11h are made in line in the vertical direction near the tip of the projection 11g. A second divided container 12 of the bottom side has a projection 12e, extending from the center of the end of the peripheral wall in the right-left direction and removably inserted into the hole 11f of the first divided container 11. Further, the second divided container 12 has a plurality of retaining projections 12f, retained by the retaining holes 11h of the first divided container 11 at the portion, corresponding to the retaining hole 11h of the first divided container 11 on the peripheral wall thereof.</p> |
