Storage container for receiving precision substrates such as wafers

摘要

A storage container for receiving precision substrates such as wafers, having increased strength and improved drying ability when washed. The storage container has a letter L-shaped circumferential wall ( 12 ) projectingly provided on an outer wall face, the circumferential wall functioning as a gasket insertion groove ( 12 a). A first flange ( 13 ) horizontally extending from the lower end face of the letter L-shaped circumferential wall ( 12 ) and a second flange ( 14 ) horizontally extending from a position 10-30 mm lower than the first flange are respectively formed integrally with the container. Vertical ribs ( 15 ) are formed between the lower face of the first flange ( 13 ) and the upper face of the second flange ( 14 ).
