PACKAGE FOR CONTAINING STORAGE DISC

摘要

It is possible to prevent generation of micro-particles by friction between a storage disc and a package. The package includes a container body (1), a lower cover (2), and an upper cover (3). The container body (1) is a bottom-less and cover-less square container having holding grooves (15) at both side surfaces (4, 4) for inserting a storage disc D. The storage disc D has a circular shape and is contained in a row in the longitudinal direction of the container body (1). The lower cover (2) covers the lower opening of the container body (1). The upper cover (3) covers at least the open top of the container body (1) and has a notch (14) and an elastic protrusion (18). The notch (14) supports the upper end of the storage disc D inserted into the holding grooves (15, 15) and suppresses deflection in the row direction. The elastic protrusion (18) protrudes in an inversed V shape at the both sides of the notch (14) so as to press downward the both shoulders of the storage disc D by its elastic force, thereby suppressing the deflection of the storage disc D in the radial direction and preventing deflection of the storage disc.
