Abstract: A storage box which can be easily modified to store flat, rectangular objects with a plurality of different widths and thicknesses is disclosed. The storage box consists of a rectangular housing member which has a plurality of straight tracks mounted on the inside surfaces of the housing ends. Two rack members may be slid into the housing along the tracks and are held in position by hooks molded into the back of the housing. Each rack member has a planar central portion with a set of ribs mounted on each side of the central portion. Within each set, the ribs are equally spaced ribs, but the spacing between the ribs differs between sets. The rack members are arranged so that when both members are inserted into the housing the spaces between the ribs form a slot into which an object to be stored may be inserted.

Abstract: A storage case for two different sizes of boxed video cassettes has a rectangular base and a complementary rectangular cover. Ribs formed on the interior of the side walls of the base define spaces for a plurality of one size of boxed video cassette between one pair of opposed side walls and spaces for a plurality of the other size between the other pair of opposed side walls. Ribs on the interior of the end wall of the base raise the lesser height cassette so that it extends the same distance above the base end wall as the cassette of greater height, whereby either cassette will fit closely under the end wall of the cover.
