Novel optical disc storage units comprising transparent polypropylene are provided. Such storage units exhibit sufficient impact resistance to protect the target disc and sufficient clarity that any informational literature may be placed entirely within the storage unit and easily viewed and read through the walls thereof without impediment. Furthermore, the target storage unit must also include a spine section of sufficient width to permit a section of the informational literature to be placed internally thereon and viewed and easily read (such as, for example, the title and accompanying language describing the target disc placed therein) substantially without impediment as well. Specific novel storage units, in addition to these necessarily transparent walls and spine portions, are also possible to maximize the benefits of the transparent properties thereof.

We claim: 1. A transparent polypropylene-containing storage unit housing informational literature, the storage unit having a first side comprising a first substantially transparent wall having an interior surface and a second side comprising a second substantially transparent wall having an interior surface, said sides being separated and integrally connected by a spine portion, wherein a first living hinge connects said first wall with said spine portion to define a first hinge line and a second living hinge connects said second wall with said spine portion to define a second hinge line, said walls and said spine portion being integrally formed of one continuous piece of polypropylene material, said promotional literature being a single sheet and provided within said storage unit in a position that is in overlying contacting relation with at least a portion of the first and second hinge lines and at least a portion of the interior surfaces of said first and said second substantially transparent walls adjacent the hinge lines and with the interior of said spine portion, said spine portion having a top end, a bottom end, and a middle area between said top end and said bottom end, wherein at least said middle area of said spine portion consists essentially of clarified polypropylene, said storage unit being adapted such that said informational literature is readily visible through said first and second substantially transparent walls and through said middle area of said spine portion of said storage unit, said storage unit further comprising at least one support member adapted to releasably hold an optical disc such that said disc is normally disposed within said storage unit in overlying relation to at least a portion of said informational literature, and wherein said support member is hingedly connected to the storage unit such that the support member and disc may be rotated upwardly and away from an underlying portion of the informational literature, whereby said underlying portion of informational literature is visible without obstruction by said disc. 2. A transparent polypropylene-containing storage unit housing informational literature, the storage unit having a first side comprising a first substantially transparent wall having an interior surface and a second side comprising a second substantially transparent wall having an interior surface, said sides being separated and integrally connected by a spine portion, wherein a first living hinge connects said first wall with said spine portion to define a first hinge line and a second living hinge connects said second wall with said spine portion to define a second hinge line, said walls and said spine portion being integrally formed of one continuous piece of polypropylene material, said promotional literature being a single sheet and provided within said storage unit in a position that is in overlying contacting relation with the interior surfaces of said first and said second substantially transparent walls adjacent the hinge lines and with the interior of said spine portion, said spine portion having a top end, a bottom end, and a middle area between said top end and said bottom end, wherein at least said middle area of said spine portion consists essentially of clarified polypropylene, said storage unit being adapted such that said informational literature is readily visible through said first and second substantially transparent walls and through said middle area of said spine portion of said storage unit and wherein the storage unit further includes at least one peripheral edge, said edge including at least one holding means for releasably securing an optical disc, said at least one holding means being either permanently or temporarily attached to said at least one peripheral edge via a hinge, wherein said optical disc may be maneuvered outside of said storage unit while simultaneously being held within said holding means which in turn remains attached to said at least one peripheral edge of said storage unit.
