Abstract

A package for storing and shipping semiconductor wafers or memory disks is disclosed. The carrier includes a bottom, a cover and a cassette. An improved closure arrangement is provided that not only secures the cover to the bottom, but also compensates for pressure differentials between the inside and outside of the package and provides for improved drainage during washing operations.
