Recording medium storage package having improved rosette

1. An enclosure for securing and storing at least one disc-shaped element having a central aperture therein, said enclosure comprising:

a substantially planar base having a first area for receiving a centrally apertured disc-shaped element;

a substantially planar cover;

a spine panel pivotably connecting said base and cover for allowing the base and cover to pivot between enclosure open and closed positions;

a two part rosette for securing said at least one disc-shaped element in said enclosure, said rosette including;

a first part centered in said area on said base, said first part comprising at least two upstanding, circularly spaced apart segments having arcuate outer peripheral surfaces dimensioned for engaging the central aperture of a disc-shaped element at circularly spaced apart positions around said central aperture;

a second part attached to said cover, said second part comprising at least two elongate, upstanding ribs extending radially from a position on said cover which is centered on said area of said base, the number of ribs on said cover corresponding to the number of segments on said base, the ribs being positioned and dimensioned such that, when the enclosure is closed, the ribs on the cover enter said first part radially inwardly of said segments on said first part with the a radial outermost edge of each of the ribs contacting the a radially inside surface of a corresponding one of said arcuate segments for biasing the arcuate segments radially outwardly to better retain a disc-shaped element when it is mounted on said arcuate segments in said first area;

wherein said cover includes a second area for receiving a centrally apertured disc, said ribs on said cover being centrally positioned within said second area, said second area being in registry with said first area when said enclosure is closed, said second part including at least two upstanding, circularly spaced apart segments having arcuate outer peripheral surfaces dimensioned for engaging the central aperture of a disc-shaped element at circularly spaced apart positions around said central aperture, said segments being positioned in said second area radially outwardly of said ribs on said cover, said first part including at least two elongate, upstanding ribs extending radially from a position on said base which is centered on said second area of said cover, the number of ribs on said base corresponding to the number of segments on said cover, the ribs on said base being positioned and dimensioned such that when the enclosure is closed, the segments on the base and cover do not contact each other and the ribs on the base enter said second part radially inwardly of said segments on said second part, without contacting the ribs on said cover, with said radial outermost edge of each of said ribs on said base contacting the radially inside surface of the corresponding segments on said cover for biasing the segments radially outwardly to better retain a disc-shaped element when said disc-shaped element is mounted on said segments in said second area, whereby said enclosure is capable of securing and storing at least two disc shaped elements having a central aperture therein.

2. An enclosure, as claimed in claim 1 , wherein there are three segments and three ribs on each of said base and cover.

3. An enclosure, as claimed in claim 1 , wherein the segments on said cover and said base are so positioned relative to each other that, when the enclosure is in the closed position, the segments on the cover are positioned between the arcuate segments on said base.

4. An enclosure, as claimed in claim 1 , wherein said segments and said ribs on said base are mounted on a raised hub centered in said first area.

5. An enclosure, as claimed in claim 1 , wherein said segments and said ribs on said cover are mounted on a raised hub centered in said second area.

6. An enclosure, as claimed in claim 1 , including radially outward extending protrusions along the upper, outer peripheral edges of said segments on said base and on said cover.

7. An enclosure, as claimed in claim 1 , wherein said first and second areas are each defined by a continuous or interrupted circular rim rising from said base and cover, respectively, said rim having a diameter dimension slightly larger than the diameter of a disc-shaped element.

8. An enclosure, as claimed in claim 6 , including at least one fingerwell defined in said upstanding circular rims and said base and cover, respectively, and communicating with said first and second areas, respectively.
